Egg tray machine product inspection standard

In order to ensure the development of egg tray machinery, we must constantly improve the performance and role of the product.

Safety Detection Technology: 

Safety is the number one keyword in any industry, especially in the egg tray industry. In the food industry, safety detection technology has developed rapidly in recent years. At present, the implementation of food safety on egg tray machinery is not limited to the scope of simple physical parameters, but also the color, raw materials and other factors of food. The range of egg tray machinery applications is expanding, which continues to place new demands on machinery manufacturers and automation product suppliers.

Motion control technology: 

The development of motion control technology in China is very rapid, but the development momentum in the packaging machinery industry seems to be weak. The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements, mainly for loading, unloading, conveying, marking, palletizing, depalletizing and other processes. Professor Li believes that motion control technology is one of the key factors distinguishing high, medium and low-end packaging machinery, and it is also the technical support for the upgrading of packaging machinery in China.

Flexible production: 

At present, in order to adapt to the fierce competition in the market, major enterprises are getting shorter and shorter. It is understood that the production of cosmetics can generally be changed in three years, even in a quarter, and the production volume is relatively large. Therefore, the flexibility and flexibility of the packaging machinery are highly demanded: the life of the packaging machinery is Far greater than the life cycle of the product. Because only in this way can meet the economic requirements of product production. The concept of flexibility should be considered in three ways: the flexibility of the quantity, the flexibility of the construction, and the flexibility of the supply.

Manufacturing Execution Systems: 

In recent years, integration technology has grown rapidly in the packaging industry. There are many types of packaging machinery and equipment such as egg tray machines, which makes the transmission interface between different manufacturers' products interface, equipment, and industrial computer, and information and equipment encounter great problems. In this case, the packaging company turned to the manufacturing execution system for a solution.

Egg tray machine mechanical properties and uses

The pulp molded product production line is made into pulp by using the pulp, if necessary, with appropriate chemical raw materials, and after vacuum, adsorption molding on a molding machine by a molding die, (some need to be dried and shaped) to produce various pulp molded products. The complete set of equipment, egg tray machine is one of the typical representatives.

Pulp molded products can be widely used in the inner packaging of various commodities such as eggs, fruits, bottled beverages, glass ceramics, handicrafts, small machinery, parts, electronics, electrical products, toys, etc., gradually replacing EPS Foam plastic and corrugated paper liner not only have good protection performance and cushioning performance, but also reduce the damage of goods, improve the packaging grade, and reduce the cost, do not pollute the environment, can be recycled and reused, which is the new wave of green packaging that is rapidly emerging today. typical.

Pulp molded products are also useful in medical, agricultural, and horticultural applications, such as disposable medical supplies that have been successfully developed, sericulture clusters, seedling nursery, seedling trays, flower baskets, flower pots, etc.; It is convenient for patients, preventing the spread of germs, promoting agricultural production, improving people's quality of life and protecting the environment.

Pulp molding is a new technology that is popular in the world and popularized in China. The country has identified it as a key environmental protection promotion project. It will grow faster with the development of the market economy and the expansion of commodity circulation. It has broad prospects. And a very strong vitality, the new requirements for the packaging of goods have also met the international standards, pulp molding is a great place. At present, the production of pulp molded products is a hot spot for investment in various places. In a short period of time, pulp molding in China will bloom like the plastics industry.

How much influence does the egg tray forming process have on the quality of the egg tray?

  The egg tray machine is a new sight in the industry after 2018, but in the face of this new scene, many customers have become hesitant about how to look at the status of the egg tray production line, because on the surface, most customers It is only seen that the increase in costs, the increase in investment is that the profit has not increased.

    At present, the egg tray production line and the pulp molding equipment production equipment are a period of industry change, that is, an excessive period that makes our industry more standardized. For investing in a new type of egg tray production line and transforming a coal-fired production line into a new gas production line, it must be the new investment in the egg tray production line, the transformation period of the transformation line is very long, and there is a reconfiguration of the old equipment and the new production line. Even some of the original production lines could not transform the gas production line.

    The electric appliance controls the solenoid valve and the cylinder part. Each solenoid valve has a proximity switch control. The cylinder has a proximity switch control solenoid valve and a solenoid valve control cylinder. The cylinder then controls the dehydration valve, wherein the four parts are mutually constrained. Failure to work causes a chain reaction that prevents the machine from working. In order to minimize the failure rate of the machine, use the machine as much as possible, reduce the number of electrical appliances, and use pneumatic components as little as possible. The machine composition should be as simple as possible and simpler. The mechanical structure is used as much as possible to make the machine simple and easy to find and easy to repair.

    The hydroforming method of paper forming is mostly used for the molding of industrial packaging products. It is used in the paper forming of egg tray machine but it is not as widely used in vacuum forming. The hydraulic forming technology of paper mold has been widely applied to our industrial packaging. Among the equipment

    In the molding process, mainly through the adsorption molding of pulp, there is a problem involving the quality of egg tray products, that is, the adsorption is not enough (vacuum degree), the product quality will be greatly reduced (such as egg tray products, no toughness, It is not caused by insufficient adsorption. The force of adsorption is derived from the suction force of the vacuum pump, that is, the force of dehydration. If it is too large, it will easily cause the mold of the egg tray product to be damaged. If it is too small, the quality will be too poor. Control of suction is important.

    Pulp molded paper products are typical green products, environmentally friendly and reusable. They are the best alternative to traditional expanded polystyrene-EPS foam products, which can effectively alleviate the problem of “white pollution”.

The pulping machine of pulp molding equipment can be divided into three types

According to the different processing materials of the egg tray machine, the pulping machine of the pulp molding equipment can be divided into three types: the high concentration pulper operating at high concentration can reach 19%; the middle concentration can be operated. Concentration pulper, the concentration can reach 12%; the operation at low concentration is called low concentration pulper, the concentration is 6%. High and medium concentration pulpers are typically operated intermittently, while low concentration pulpers are typically operated continuously. The size of the rotor is determined by the concentration of the slurry and the pulping system.

    Egg tray equipment molds are used at a high frequency. Each time the mold is opened and closed, it will cause wear and tear on itself. Under long-term use, the wear will accumulate to a certain extent, and the mold performance will decrease until the end of life is scrapped. Therefore, it is necessary to summarize the experience of egg tray equipment mold operation.

    Precautions for the use of egg tray equipment molds Remember to lubricate the mold before use, try to reduce the friction of each mold operation and prolong the service life. Do not directly touch the mold with your hands before the machine stops working to prevent people from being hurt. When not in production, the egg tray machine equipment mold should first clean the mold cavity debris, and then put on anti-rust oil. Use special clamps to pick and place products and reduce work. Regularly check the measurement mold size, record the data, and perform mold loss analysis to control the product quality within the qualified range.

    The use of low-grade raw materials to packaging high-value items is the economic basis for paper mold industrial packaging materials to obtain better returns. Paper mold industrial paper trays generally use paper box scraps and old newspapers as raw materials. They are low in value and sufficient in supply, and the packaging objects are often high-end electronic products, mechanical parts, and crafts. For example, computer hardware, audio, mobile phones, fax machines, high-end phones, micro motors, auto parts, lamps, and so on.

    In the forming process of pulp molded products, it is necessary to enter the mold multiple times to complete the manufacturing process of the product. It is said that the pulp molded products are formed on a single convex or concave mold, and the cavity must be formed after the forming of the concave and convex molds after forming. In the middle transfer, the wet paper blank transferred to the shaping die is formed by pressing and heating in the shaping die. Therefore, the pulp molding mold is divided into a forming mold, a shaping mold, a shaping mold, and a die-cutting mold. There are two types of forming processes, one is adsorption forming, the other is press forming, and the press forming mold is somewhat similar to a rubber plastic mold. The adsorption forming mold is special and complicated.
