Analysis on the development trend of food packaging machinery

according to the information provided by the World Packaging Organization, the global packaging turnover has exceeded US $500billion. The development of food packaging machinery in the world is aimed at the requirements of large customers, so as to drive the development of related machinery. The requirements of large customers are mainly reflected in the following aspects:

first, the higher the requirements for production efficiency, the better. In this way, the standard can be increased by 10000 times, the cost of a single product can be reduced, the delivery time can be met, and the process circulation cost can be reduced. At the same time, the high-speed packaging machine requires relevant connection with the previous process, without handling links, including control connection. The whole production line should be started in reverse order and stopped in sequence according to the production and packaging process. For example, the cold filling production line automatically goes online from plastic raw materials to beverage filling and large package stacking in the closed workshop

second, it can adapt to the update and change of products. Because the life cycle of the product is much shorter than the service life of the equipment, changing the product and packaging will not replace the expensive packaging production line, so the packaging machinery is required to have high flexibility and flexibility, and the production line allows the size of the packaging to be changed within a certain range

third, input the common faults and solutions of the equipment into the computer in advance. When the equipment has common faults, it can diagnose by itself, and can also implement remote diagnosis and troubleshooting

fourth, automatic recognition function. On the one hand, it can automatically identify the thickness, hardness, rebound force, etc. of packaging materials, and feed back to the machine through the computer to make the machine adjust the action. On the other hand, it has the function of high-speed vision. The arrangement of various products is regular, while the products delivered by the production line are disordered. You can scan with a probe to determine the position of materials of different shapes, and then feed back to different manipulators. It will accurately put the items into the package according to the exact position and direction, which is fast and accurate, unlike the fatigue of vision and fingers caused by manual work

fifth, minimize pollution in the production and packaging process, including noise, dust pollution, sewage, etc., and minimize waste. The internationally advanced method is to adopt computer simulation technology, which greatly shortens the design cycle of packaging machinery (production line) and greatly improves customer satisfaction

the application of this simulation technology reminds that the manufacturing of packaging machinery should be modularized according to the functions of components. Each component has a unified interface, and each module can be freely combined. In this way, the single piece small batch production of packaging machinery can be changed into the batch production of various modules, so as to reduce the production cost. Even if it is not a production line but a single machine, modular combination can also shorten the design and manufacturing cycle and reduce production costs. Modularization can make non-standard parts standardized, make it convenient for users to troubleshoot, and reduce users' operating costs

foreign food packaging machinery has been ahead of China for many years in terms of production process, equipment stability, manufacturing level and design concept. For example, the international advanced filling production line can achieve 120000 cans per hour long ago; A filling production line can sell for 200million yuan; There are only 3 people in the whole filling production line; The film wrapping machine can open 300 bags per minute

in recent years, the domestic dairy industry has developed explosively, and only a few leading companies have imported dozens of production lines, which undoubtedly provides a broader market for foreign equipment suppliers

fortunately, due to the development and expansion of the domestic food packaging machinery industry, China is rapidly catching up, shortening the gap, providing products that can meet most of the domestic demand, and creating a "China threat" in the world, which greatly reduces the price and profit of foreign products and enhances the competitiveness of domestic equipment

the domestic food packaging machinery market has a huge space

in China, food is the most important thing for the people. With the reform and opening up and the improvement of people's living standards, especially in the past ten years, China's food and beverage industry has shown a momentum of sustained and rapid development, with the total output increasing by more than 20% every year. The annual sales volume of the food industry reaches more than 200 billion yuan. In recent years, the imported equipment can not be manufactured domestically or the manufacturing level is far from it. Import represents our gap

the problem of food safety has been concerned by the whole country. If it is left unchecked, it will affect people's physical ability to flexibly change the speed and methods of experiments, physical health, reduce people's living standards, and will have a serious negative impact on social stability, the food industry and even the entire economic development. Therefore, the state will strive to improve the level of science and technology and equipment in the field of food

as China's food and packaging machinery industry has been formed for only 20 years, which is the period of the world's fastest technological development, new technologies are constantly applied in this industry, while the domestic industry has a weak foundation and insufficient technology and scientific research strength, and its development is relatively lagging behind, dragging down the food and packaging industry to some extent. Although the overall development is fast, the food and packaging industry is developing faster, and the gap has widened. It is predicted that by 2010, the total output value of the domestic industry will reach 130billion yuan (current price), while the market demand may reach 200billion yuan. The hole in this market will be filled by foreign equipment. The goal of our country is to narrow this hole, to catch up with the world's advanced level for the food industry, and to make the big packaging country move forward to the powerful packaging country, to provide advanced technical equipment, so that the imported equipment can only play the role of picking up the leftovers and filling the gaps in the domestic market. This requires the annual development rate of domestic food and packaging machinery to exceed 18%, and the output value rate of new products to reach 25%

at present, a prominent problem of China's food and packaging machinery is the long development cycle of new products, more imitation and less new creativity, which is not only related to the development of related industries, but also related to the knowledge level of designers

the high labor and after-sales service costs of foreign equipment will force them to expand with users at a low cost and localize production and services. Many large companies have decided to give priority to similar domestic equipment, which brings additional opportunities to the development of China's packaging machinery industry; At the same time, with the rapid progress of domestic basic industry and the unremitting efforts of domestic peers, the status of domestic equipment has become higher and higher, such as the filling production line with about 20000 bottles per hour has been difficult to see foreign equipment

development of secondary packaging machinery

all mechanical equipment for post-processing of finished products are collectively referred to as secondary packaging machinery, which is actually what we often call general packaging machinery, which can be roughly divided into product inspection, sorting, counting, weighing, bagging, packing, film packaging, packaging, labeling, inkjet, transportation, stacking, winding, unmanned transit Many models such as automatic storage decided to carry out relevant industrialization research in the field of polylactic acid. Now let's take a look at two specific solutions for secondary packaging, with a view to discussing the new development of packaging automation

automated production of film packaging machine

Coca Cola and the latter part of the fifth quarter used a simple film packaging machine. The machine adopts automatic bottle separation technology and can run; The whole machine is controlled by PLC, with a high degree of automation and intelligence; Adapt to a variety of bottle types, easy to adjust; With multiple safety protection, with touch screen control; Adopt high-efficiency heating and insulation technology, and shrink the tunnel with less heat dissipation; Imported famous brand components are used for motors, cylinders and electric controls; It can be analyzed and set according to the specific requirements of users to effectively ensure the quality of finished products

the simple film packaging machine implements full-automatic film packaging, offline manual film packaging, and the automatic operation is divided into the following steps: conveying bottles: the products to be packaged enter the conveyor belt through oscillating bottles, and it is convenient to change the bottle type and change the arrangement and combination; Bottle stacking: the products to be packed are divided into the same bottle stack by the bottle splitting servo motor; Film transport: transport the film through the given signal; Hot cutting film: the film is cut into equal lengths by the rotating hot cutting film knife. When packaged with color film, the cutting can always reach the exact position; Film coating: the film driving rod guides the film around the package to be packaged and overlaps at the bottom of the package. The film driving rod driven by the servo motor can always tightly wrap the film around the package; Film package heat shrinkage: the film is tightly shrunk around the package by the hot air, so that the package to be packed closely together, and the temperature can be fast and high-speed to achieve the best shrinkage effect; Cooling: the finished film package after heat shrinkage is cooled through the cooling channel, and finally unloaded from the conveyor belt or connected to the storage bin

in addition, products must enter the machine at a relatively stable speed, and the conveying speed of upstream products should be controlled to prevent excessive extrusion between products. At the outlet, the packaged products must be carefully and timely removed to ensure the normal packaging process

automated production of destacker

Hong Kong Swire Coca Cola uses destacker to destack cans. Its working principle is: the forklift truck places the empty can stack on the stacking conveyor belt, and then transports it to the unpacking platform. After manual unpacking, it is sent to the preparation area, and then enters the shaft bottom platform, which is driven by the lifting shovel to the set position. The paper suction tray mechanism sucks up the paper sheet (or layer partition) and sends it to the paper sheet (or layer partition) conveyor trolley, and then the bottle clamping trolley clamps the can layer and pushes it onto the can conveyor belt. At the same time, The paper sheet (or layer partition) conveying trolley transports the paper sheet (or layer partition) to the stacking mechanism and returns to the original position. This series of actions are cyclic, unloading the cans layer by layer onto the can conveyor belt, completing the unloading of objects like sesame seeds, which are actually quartz crystal resonator shell cans. After the whole stack of empty cans is unloaded, the pallet is lowered to the stacking conveyor belt and transported to the bin machine for stacking. After the pallet is stacked to the set height, it is transported to the stacking out position, and the pallet is forked away by a forklift

at present, the competition of food packaging machinery is becoming increasingly fierce. In the future, the technical requirements of food packaging machinery for industrial automation will be higher and higher, so as to improve the overall level of packaging equipment. Packaging machinery enterprises will also develop food packaging equipment with multi-function, strong performance, high efficiency and low consumption
