Mesh belt type composite foaming device for plastic floor production

Abstract

The invention discloses a mesh belt type composite foaming device for plastic floor production, and relates to the technical field of plastic floor production. The mesh belt type composite foaming device for plastic floor production comprises a barrel, a stirring ventilation mechanism, an extrusion mechanism and a circulation mechanism are arranged on the barrel, two sets of arc-shaped frames arewelded to the top of the barrel and are symmetrically distributed, an installation frame is welded to the outer surface of the bottom of the barrel, and a sealing cover is installed at an opening at the front side of the barrel in a threaded manner. According to the mesh belt type composite foaming device for plastic floor production, a stainless steel mesh belt extrudes a plastic raw material anda foaming agent which are reacting in the barrel in a reciprocating manner, the plastic raw material and the foaming agent continuously penetrate through gaps in the stainless steel mesh belt to achieve forced cutting and mixing, and therefore the plastic foaming quality of the device is improved; and the reaction efficiency rate is increased, the reaction time is shortened, the practicability and production efficiency of the device are improved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of plastic floor production, in particular to a mesh belt type composite foaming device for plastic floor production. Background technique [0002] Plastic floor, also known as plastic floor, is a floor laid with plastic materials. Plastic floor can be divided into two types according to its use state: block material and coil material. According to its material, it can be divided into hard, semi-rigid and soft (elastic) Three types, according to their basic raw materials can be divided into several kinds of polyvinyl chloride plastic, polyethylene plastic and polypropylene plastic, etc. Some soft coiled plastic floors mostly use foamed plastics as raw materials, and the microporous structure of the foamed plastics itself It has the characteristics of light weight, good cushioning, heat insulation and sound absorption performance, and is suitable as a decoration material. [0003] In the production process o...

AI Technical Summary

Problems solved by technology

[0003] In the production process of foamed plastic flooring, it is necessary to mix the granular plastic raw materials with the foaming agent to make them fully react to obtain a foamed plastic melt, and then Extruders are used for molding processing. At present, most plastic foaming devices can only carry out simple stirring and heating treatment. There is a problem of uneven mixing of plastics and foaming agents, and the air circulation speed inside the device is slow during the production process. When reacting with the foaming agent, there is not enough air as a support, the reaction rate and quality are low, and the micropore size and distribution in the actual foamed plastic melt are not uniform, which affects the actual quality of the finished product, and this type of device is difficult to clean The problem is that the foamed plastic melt is easy to stick and solidify in the device, which affects the subsequent production operations and the service life of the device, and the actual use effect is poor
