Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of raw material melting, in particular to a raw material melting device for producing fresh-keeping film. Background Art
[0002] Cling film is a plastic packaging product, usually made through polymerization reaction with ethylene as the masterbatch. Cling film can be divided into three categories: the first is polyethylene. PE film has moderate water permeability and air permeability, which is suitable for food preservation, and its safety is higher than PVC. The second is polyvinyl chloride, referred to as PVC. PVC cling film has good transparency, certain viscosity, and is inexpensive. If it comes into contact with greasy food, is heated at high temperature or heated in a microwave oven, plasticizers may migrate out. The third is polyvinylidene chloride, referred to as PVDC. PVDC cling film has high barrier properties and is suitable for packaging cooked food and meat products. It has the highest heat resistance and can be used for microwave heating, but the price is relatively high;
[0003] It is widely used in food packaging fields such as microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging, etc., in family life, supermarkets, hotels and restaurants, and industrial production;
[0004] In this way, when the cling film is processed and produced, the raw materials and Xining need to be melted and processed. However, the traditional melting device cannot achieve stirring and screening of the raw materials during processing. In this way, the raw materials cannot be fully mixed during the processing, resulting in incomplete melting, which affects the processing quality of the cling film.
[0005] After searching, Chinese patent publication number CN202122188640.8 discloses a raw material melting device for cling film production; it comprises a box body, a protection box is fixedly installed on the left side of the top of the box body, a motor is fixedly installed in the inner cavity of the protection box, a rotating shaft is fixedly installed on the output end of the motor through a coupling, a driving wheel is fixedly installed on the bottom end of the rotating shaft, a heating plate is fixedly installed in the inner cavity of the box body, a connecting rod is fixedly installed on the top of the inner cavity of the box body, a driven gear is fixedly installed on the bottom end of the connecting rod, a rotating column is fixedly installed on the bottom end of the driven gear, and a stirring paddle is fixedly installed on the bottom end of the rotating column. The raw material melting device for cling film production drives the driven gear to rotate forward and reversely through the rotation of the driving wheel, and the rotation of the driven gear drives the stirring paddle to rotate forward and reverse, and cooperates with the synchronous rotation of the small agitator, thereby achieving the effect of uniform melting of the cling film raw material;
[0006] The device in the above patent uses a stirring paddle to stir the raw materials when melting them, which cannot effectively ensure that the raw materials are fully mixed during stirring. In addition, the filter plate in the above patent may be missed during stirring by the stirring paddle, which will cause different melting times of the raw materials, resulting in different processing qualities of the cling film, affecting the quality of the cling film.
[0007] In view of the above situation, we provide a raw material melting equipment for the production of cling film. In this device, the raw materials are loaded into the upper barrel through a feed pipe, and the raw materials are transmitted to the top of the upper barrel through spiral feeding teeth. The connecting plate is driven to rotate by the rotating shaft, and the connecting rod installed on the connecting plate is driven by the driven runner to rotate along the inner ring of the gear ring. While realizing the rotation of the connecting rod, the stirring teeth on the connecting rod can also mix the raw materials. The mixed raw materials fall into the heating plate below through the sieve plate, and the heating plate is used to melt the raw materials. The melted raw materials fall into the bottom of the tank through the gap between the heating plate and the upper barrel, and are then connected to the negative pressure device through the discharge pipe to extract the melted raw materials.
