Problems solved by technology

[0004] In order to make up for the shortcomings of the existing technology, the area of ​​the shear groove of the existing extruder is fixed, and the area of ​​the shear groove cannot be adjusted according to the material. The applicability is poor, and the material with good extrusion performance will pass through the shear groove in large quantities. , so as to block the suction port of the vacuum machine, and the materials with poor extrusion performance will pass through the shearing groove in a small amount, which will lead to the problem of glue shortage in the extrusion section. The present invention proposes a pin exhaust in the vacuum section with adjustable flow rate extruder

Abstract

The invention belongs to the field of extruders, and particularly relates to a vacuum section flow adjustable plasticizing section pin exhaust extruder. The vacuum section flow adjustable plasticizing section pin exhaust extruder comprises a rack, a first shell, a second shell, a screw, an exhaust assembly and a plasticizing assembly; the first shell is mounted at the top of the rack; a feeding groove is formed in the top of the first shell; the second shell is fixedly connected to the side face of the first shell; the screw is arranged in the first shell and the second shell; and the end part of the screw is mounted in the first shell. According to the vacuum section flow adjustable plasticizing section pin exhaust extruder, an adjusting ring, the screw and an adjusting rod are arranged, through mutual cooperation of the parts, the size of the section of a shearing groove can be adjusted, so that the section of the shearing groove is matched with the extrusion performance of materials, the screw does not need to be replaced independently according to the materials, the applicability is high, factory production is facilitated, and meanwhile the stability of the section of the product can be improved.

Description

technical field [0001] The invention relates to the field of extruders, in particular to a plasticizing section pin exhaust extruder with adjustable vacuum section flow. Background technique [0002] Extruder is a kind of machinery for plastic rubber production. Extruder can be roughly divided into twin-screw extruder, single-screw extruder, multi-screw extruder and screwless extruder. [0003] In the current existing technology, the extruder can be divided into a feeding section, a plasticizing section, an exhaust section, a pumping section, and an extrusion section. The material will be extruded, the plasticizing section relies on high temperature to melt the material, the exhaust end discharges the air in the material through the shear groove and the screw, and the air extraction section extracts the air discharged from the material through a vacuum machine, so as to enhance the material's durability. Physical properties, but there are many kinds of materials, and the vi...
