Recently, the author ’s mobile phone friend circle was screened by Alibaba ’s “unmanned supermarket”. There is no salesperson or cashier, just swipe the QR code to enter the store, select the goods and take them away, and the mobile phone will automatically deduct the corresponding amount. It is understood that the goods in the store are using RFID technology. Electronic tags are affixed to the articles and can be sensed when passing through the area of the reader. At present, although the penetration rate of "unmanned supermarkets" is still low, the use of RFID technology in supermarket products has promoted the development of smart packaging. Reflected from the side, smart packaging will become a development trend in the packaging industry in the future.
As the saying goes, "People rely on clothes and saddles." Appearance packaging is very important for various industries, and of course the food packaging industry is no exception. With the arrival of the concept of Industry 4.0, product packaging is gradually developing towards high-end, so smart packaging has also emerged as the times require. Recently, companies such as Shenzhen Jinjia Color Printing and Meiyingsen (002303) have announced their entry into the field of smart packaging, and predict that the smart packaging market space will reach trillions. At present, the technology used in smart packaging is RFID technology, which can identify multiple electronic tags at the same time, and the operation is fast and convenient. There is a variable data barcode, and smart label QR code is also a technology widely used in smart packaging. Intelligent packaging intelligence mainly reflects three aspects. We take food packaging as an example. On the one hand, it can detect the environmental conditions of packaged food. On the other hand, it can provide information about the quality of food packaging during circulation and storage. , To maximize the protection of consumer rights and interests, to achieve product traceability. As a new industry, smart packaging has developed rapidly abroad and its applications are also widely used. However, China's development is still immature and is still in its infancy.
It is understood that there was a report in the United States on "Active and Intelligent Packaging", showing that while the population of the United States is aging, the trend of intelligent packaging is also expanding. Relevant experts predict that the market value of intelligent packaging in the United States in 2017 will reach more than 3 billion US dollars. In the next three years, its compound annual growth rate will be 8%. Among them, pharmaceutical packaging is expected to become the fastest growing application market for intelligent packaging in the United States in the next few years. Recently, Jones Packaging Company of London, Ontario, Canada has begun to "smart packaging" medicines. The introduction of an interactive "smart label" through a convenient method has changed the traditional way consumers buy medicines, especially over-the-counter medicines. The "smart tag" has built-in sensors and tracking devices that enable consumers to "talk" to the product. In addition, Finland has begun to use smart packaging technology in alcoholic products. By applying Speed Tap tags to wine bottles, remote tag management, customized content delivery, data analysis and reporting can be achieved. The most important thing is that each tag is unique, it is almost impossible to copy, and then through NFC technology, users can read the relevant information. Compared with foreign countries, China's smart packaging technology and applications are relatively mature in terms of modified atmosphere packaging and aroma release packaging, but the technical content is not high. The application and popularization of smart packaging technology as a whole will take time.
The future development trend of smart packaging and the huge potential market indicate that this industry is expected to become a new growth point for China's economic development, and will also lead the packaging industry to develop in an intelligent direction, especially the food packaging industry. At present, China's food packaging industry has basically realized automation, such as the application of automatic packaging machines, but intelligent packaging has not yet gained popularity. Compared with foreign countries, the application of smart packaging technology in China is still very low. They all say, "People go high, and water flows low." The packaging industry has always been pursuing new intelligent packaging machinery with high technological content, high degree of automation and high production efficiency. With this, I hope that packaging machinery companies can seize this development opportunity, accelerate the pace of scientific and technological research and development, and promote the development of intelligent food packaging in China, so that intelligent packaging can enter consumers'
Several keys to the maintenance of packaging machinery: cleaning, fastening, adjustment, lubrication, and corrosion protection. In the normal production process, each machine maintenance staff should do, according to the maintenance manual and maintenance procedures of the machine packaging equipment, strictly perform various maintenance work within the prescribed cycle, reduce the wear rate of parts, eliminate the hidden danger of failure, and prolong The life of the machine. Anhui Xinyuan Packaging Editor shared with you the maintenance is divided into: routine maintenance, regular maintenance (points: first-level maintenance, second-level maintenance, third-level maintenance), special maintenance (points: seasonal maintenance, out of service).
Primary maintenance of mold:
The first-level maintenance of the mold refers to the daily maintenance of the mold by the operator during production. The main content is cleaning, lubrication and inspection.
A. Maintenance during mold loading:
1. Clean the upper and lower surfaces of the mold before loading the mold to ensure that the mold mounting surface and the press table are not crushed and the parallelism of the upper and lower mounting surfaces of the mold during production;
2. After the mold is installed, open the mold and clean all parts of the mold, especially the guide mechanism. For the surface part mold, the profile should be cleaned to ensure the quality of the part;
3. Lubricate and grease the sliding parts of the mold;
4. Inspection of all parts of the mold, especially safety parts. Such as: safety side pins, safety screws, side guards, punching waste channels, etc.
B. Maintenance during production:
1. Periodically oil the corresponding part of the mold during production. Such as: blanking rings and rounded corners of the drawing die; knife edge parts of the trimming die; flanging knife block parts, etc .;
2. Regularly clean the small hole waste channel of the trimming punching die.
C. Post-production maintenance:
1. A comprehensive inspection of the mold is required after production is completed;
2. Comprehensively clean the mold to ensure the cleanliness of the mold;
3. Clean up the waste in the mold to ensure that there is no waste in the waste box;
4. Feedback the usage status of the mold and the actual situation to the "Working Ticket for Mold Use".
Secondary maintenance of the mold:
The secondary maintenance of the mold refers to the regular systematic maintenance of the mold based on the technical status and complexity of the mold. This maintenance work is completed by the mold repair personnel, and a record is made according to the maintenance situation. The requirements and methods of the second warranty are described below for different parts:
A, drawing die convex die, concave die:
The main problem of the convex and concave dies of the drawing die is the burring of the burrs and the profile. During the maintenance, the rounded burrs of the mold are polished. If pitting occurs, repair the mold and repair it.
B. Guide parts (guide post, guide bush, guide plate, etc.):
There will be pull marks and other phenomena during the work of the mold. The main causes are dirty lubricant and uneven guide clearance. When the guide part has a pull mark, it is eliminated by pushing it with a stone and then polishing it;
C. Trimming edge:
During the use of the mold, the knife edge part is prone to chipping and edge collapse. At this time, the damaged part of the mold must be repaired and repaired;
D, spring and other elastic parts:
During use, the spring is one of the most vulnerable parts of the mold, and it usually shows fracture and deformation. The method adopted is replacement, but the specifications and models of the springs must be paid attention to during the replacement process. The specifications and models of the springs are determined by the three items of color, outer diameter and length, and they can only be replaced if all three items are the same;
E, punch, punch sleeve:
Most of the punches and punches used on the mold are standard parts. During the use of the mold, the punches are prone to break, bend and chip, and the punches are generally chipped. The damage of the punch and the sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the mounting part, and the length.
F. Fastening parts:
Check whether the fastening parts are loose or damaged. The approach taken is to find replacement parts of the same specifications;
G. Pressing and discharging parts:
Pressing parts such as blanking plate, urethane, etc., unloading parts such as unloading plate, pneumatic jacking device, etc. Check the assembly relationship of each part for damage during maintenance and repair the damaged part. Inspect the pneumatic jacking for leaks and take action on specific conditions. If the trachea is damaged, replace it. (Reprinted from the mold material network)
