Raw material melting device for dust-free PE bag production

Abstract

The invention discloses a raw material melting device for dust-free PE bag production. The raw material melting device comprises rolling wheels, a melting box and an inclined plate; when the raw material melting device is in use, the raw materials are pushed into a heating box through a feeding hole, and the heating box carries out first heating on the raw materials; then the raw materials are pushed into the melting box through a spiral pushing rod, and an extruding condition exists in the pushing process; the raw materials can be extruded and crushed, so that better subsequent heating and melting can be facilitated; furthermore, the raw materials enter a vibration net, and second heating is carried out through a heating net on the vibration net; the small particle raw materials are leaked to the bottom of the melting box through vibration during the heating process; the raw materials at the bottom of the melting box are finally heated and melted through a heating pipe inside a stirring rod and a heating block in the inclined plate; and after being completely heated and melted, the raw materials are discharged through a discharging port. By virtue of the overall design of the device, the raw materials can be fully melted, so that the quality of the product is guaranteed; and the device is convenient and rapid to use and operate, very high in practicability and convenient to popularize.

Description

technical field [0001] The invention relates to the field of plastic bag production equipment, in particular to a raw material melting device for dust-free PE bag production. Background technique [0002] PE is the abbreviation of polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin; it is a kind of transparent plastic bag, which can be used for packaging of clothing, bags, electronic products, etc. In the production process of PE bags, the raw materials required for production need to be processed first. Melting, and then through film injection and cooling to finally make a finished product. At present, many enterprises have uneven heating of raw materials in the process of raw material melting, resulting in incompletely melted raw material particles at the time of final film injection, which affects the quality of the final product. , In addition, more and m...

Problems solved by technology

In industry, it also includes copolymers of ethylene and a small amount of α-olefin; it is a kind of transparent plastic bag, which can be used for packaging of clothing, bags, electronic products, etc. In the production process of PE bags, the raw materials required for production need to be processed first. Melting, and then through film injection and cooling to finally make a finished product. At present, many enterprises have uneven heating of raw materials in the process of raw material melting, resulting in incompletely melted raw material particles at the time of final film injection, which affects the quality of the final product. , In addition, more and more companies are beginning to pay attention to the development of energy conservation and environmental protection. Therefore, it is very necessary to design a raw material melting device for PE bag production.
