Gear pump glue stock filtering extruder

Abstract

The invention relates to a gear pump glue stock filtering extruder. The invention is characterized in that the extruder is provided with an extruder body; a glue stock flow channel straightly penetrates though the extruder body; first and second gears are arranged at the upper and lower positions of the front side of the glue stock flow channel in front and back mesh modes, wherein the two first gears are meshed; two meshed third gears are arranged at the front side of the glue stock flow channel; a glue stock divergent die is transversely arranged in the middle of the back half section of the glue stock flow channel; and a filtering discharging device is combined with the front end of the glue stock flow channel. When using the extruder, material slices are put in the glue stock flow channel from the back and pressurized by the two first gears, the material slices are mixed at the periphery of the glue stock divergent die, and then pressurized by the two third gears again to be forwardly output through the filtering discharging device at the front end. Because the glue stock is mixed and pressurized in a gear pump manner, the extruder has the effect of no raw material residue, big pressure and good mixing effect.

Description

Technical field [0001] The invention relates to a rubber material filtering and extruding machine, in particular to a gear pump rubber material filtering and extruding machine with no remaining rubber and good filtering effect. Background technique [0002] The existing rubber filter and extruder is equipped with a motor-driven screw in the machine body. When the rubber material is put in from the upper hopper, the rubber material is pushed forward along the pipe in the machine body through the rotating screw. In the process of rubber material mixing, the rubber material can be mixed by the pressure of pushing, and then the rubber material is pushed to the front end of the pipe, filtered through the filter screen at the front in order, and finally extruded into the desired shape by the mold. Output. [0003] Although the aforementioned existing rubber filter extruder can mix the rubber and filter it out, it is easy to leave the rubber between the rear end of the screw and the pipe...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned existing rubber material filter extruder can mix the rubber material and then filter and output, but because the screw is rotated to pressurize, the rubber material is easy to remain in the gap between the rear end of the screw and the surrounding pipe during the transportation process. In addition, the pressure generated by the screw rotation conveying method is small, so the mixing effect generated during the conveying process is not good, and it is impossible to produce better quality rubber output
