Plastic forming material pretreatment auxiliary device capable of efficiently improving melt uniformity

Abstract

The invention provides a plastic forming material pretreatment auxiliary device capable of efficiently improving melt uniformity, and belongs to the technical field of plastic forming material pretreatment devices. The plastic forming material pretreatment auxiliary device comprises a driving supporting column, the top end of the driving supporting column is connected with a melt transfer chamber, the driving supporting column is sequentially sleeved with an annular filtering cavity and an annular bearing cavity, through holes are evenly formed in the bottom face of the annular filtering cavity, a friction shaft is arranged in the annular filtering cavity, and a limiting ring is connected between the friction shaft and the driving supporting column. According to the plastic forming material pretreatment auxiliary device capable of efficiently improving the melt uniformity, the annular filtering cavity and the melt transfer chamber are synchronously driven to rotate through rotation of the driving supporting column, and through combined use of through holes, the friction shaft and a magnetic limiting piece, the activity of the melt can be increased, remedial treatment can be conducted, meanwhile, the through holes are subjected to anti-blocking treatment, so that the filtering efficiency and the uniformity of the melt are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pretreatment devices for plastic molding materials, in particular to an auxiliary device for pretreatment of plastic molding materials that improves the uniformity of melt with high efficiency. Background technique [0002] The plastic molding process is mainly a process of plasticizing plastic molding materials through a series of processing procedures. One of the main processing procedures is to melt and decompose the plastic molding materials. An important factor of quality, which mainly affects the quality of molding from the uniformity of the melt and the concentration of the melt. [0003] In order to improve the uniformity of the melt, the existing filter device is usually used to pre-filter the melt before forming to improve the uniformity of the melt. Adhesion affects the filtration amount of the melt per unit time and reduces its filtration efficiency. At the same time, it will also cause block...

Problems solved by technology

[0003] In order to improve the uniformity of the melt, the existing filter device is usually used to pre-filter the melt before forming to improve the uniformity of the melt. Adhesion will affect the filtration amount of the melt per unit time and reduce its filtration efficiency. At the same time, it will also cause blockage of the mesh, which seriously affects the filtration of the melt. Concentration and uniformity have a certain influence
