Raw material melting treatment system for film production

Abstract

The invention discloses a raw material melting treatment system for film production, and relates to the technical field of film production. The raw material melting treatment system comprises a raw material preheating box, wherein a servo quantity control mechanism is fixedly arranged on the top end surface of the raw material preheating box; the servo quantity control mechanism comprises an anglesensor and a servo motor which are correspondingly and fixedly arranged on the top end surfaces of a support plate A and a support plate B; the servo quantity control mechanism also comprises a quantity control assembly fixedly connected with the top end surface of a discharging hopper; through being matched with the front servo motor, a linkage tube B can be linked; further, a regulating disc Bfixedly connected with the linkage tube B is driven to synchronously rotate; in the rotating process of the regulating disc B, each material falling hole A and each material falling hole B generate relative displacement; the control on the raw material falling quantity can be realized, so that the problem of blockage in the whole melting treatment system due to nonuniform falling quantity can be avoided; and the repair frequency of the whole melting treatment system in the daily use process is reduced.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a raw material melting processing system for film production. Background technique [0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as laminations. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] In the production process of the film, it is necessary to turn the raw material of the film into a molten state, and then use the film blowing machine to blow the film raw material in the molte...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a raw material melting processing system for film production, which solves the problem of adding film to the feeding place of the whole system through the external feeding pipe structure when the melting processing system is working normally. Granular raw materials, after the above-mentioned raw materials enter the whole system, because of the inability to accurately control the amount of blanking, the problem of blockage often occurs in the melting chamber of the whole system, which makes the frequency of downtime for refurbishment higher and the melting processing system in During normal operation, the melting chamber of the system is exposed to the environment and lacks a protective structure. On the one hand, the heat inside the melting chamber spreads outward, resulting in waste of thermal energy resources. On the other hand, it is easy to cause safety accidents and the safety factor of the staff Lowering the problem
