Polyethylene plastic bag preparing and processing system

Abstract

The invention provides a polyethylene plastic bag preparing and processing system. The polyethylene plastic bag preparing and processing system comprises a supporting frame, a mixing and stirring mechanism and an extruding and slitting mechanism. The system can solve the following problems that exist in the preparation process of polyethylene plastic bags a, in the granulation preparation process of polyethylene plastic, raw materials are mainly heated and melted for mixing and stirring, a traditional stirring device is limited in stirring range, has one-sidedness in stirring and cannot achieve the degree of sufficient stirring during stirring, and meanwhile, the molten raw material has a certain adhesion type, so that the molten raw material is prone to being adhered to the inner side wall of a stirring container; and b, when the molten raw material is extruded and shaped, the raw material is in a non-solidified state during extrusion due to a certain high temperature, and when the raw material is cut off by using a cutter, the raw material is prone to being adhered to the cutter, even the granulation cutting effect is influenced, and the wire drawing phenomenon is easily caused.

Description

technical field [0001] The invention relates to the technical field of polyethylene plastic bags, in particular to a preparation and processing system for polyethylene plastic bags. Background technique [0002] Polyethylene (PE) is one of the five major synthetic resins. It is the variety with the largest production capacity and the largest import volume among synthetic resins in my country. Polyethylene is mainly divided into linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene. Polyethylene (HDPE) three categories. PE is relatively soft and has a waxy texture to the touch. Compared with the same plastics, it is lighter in weight and has a certain degree of transparency. When it burns, the flame is blue, and it is non-toxic and harmless to the human body. It is widely used in plastic wrap, vest-style plastic bags, plastic food bags, baby bottles, pails, kettles, etc. [0003] At present, the following problems exist in th...

Problems solved by technology

[0005] The invention provides a preparation and processing system for polyethylene plastic bags, which can solve the following problems in the preparation process of polyethylene plastic bags: a. During the granulation and preparation of polyethylene plastics, the raw materials are mainly mixed and stirred by heating and melting , the traditional stirring device has a limited stirring range during stirring, and the stirring is one-sided, which cannot achieve a sufficient degree of stirring. At the same time, because the molten raw material has a certain adhesion type, it is easy to stick to the inner wall of the stirring container; b. The molten raw material is in the When extruding and shaping, due to its high temperature, the raw material is not yet solidified during extrusion. At this time, when cutting with a cutter, the raw material is easy to stick to the cutter, and even affects the cutting effect of granulation, and is prone to stringing Phenomenon
