Free Fall Feeder

Abstract

The invention relates to a free falling feeding machine. The feeding machine comprises a first layered tapered hopper which is connected with a lower outlet of a tapered mixer, wherein the lower outlet of the tapered mixer leans on the right side of the hopper wall of the first layered tapered hopper; a second layered tapered hopper, wherein the outlet of the first layered tapered hopper leans on the right side of the border wall of the second layered tapered hopper; and a third layered tapered hopper, wherein the outlet of the second layered tapered hopper is disposed on the center of the material inlet of the third layered tapered hopper, the material outlet of the third layered tapered hopper is disposed in a vertical direction of the material inlet of a twin-screw rubber making machine, and a triangular blade which is connected with a speed regulating motor is arranged in a part over the material outlet of the second layered tapered hopper. The free falling feeding machine of the present invention has the advantages that the increase and decrease in discharge caused by the gravitational acceleration can be forcedly controlled, the purpose of uniform feeding can be reached, and stable performances of products can be ensured.

Description

technical field [0001] The invention relates to a synthetic rubber production line, in particular to a feeder in the production line. Background technique [0002] The production line of synthetic rubber machine is: put 20% of rubber SIS, 30% of naphthenic oil, and 50% of petroleum resin into the conical stirring pot to stir evenly, and the prepared raw materials are delivered to the inlet of the twin-screw rubber making machine In the feed port, the twin-screw rubber machine is used for high-temperature roasting and high-speed mixing, and the adhesive extruded through filtration becomes synthetic rubber. [0003] Depend on figure 1 Visible: the structure of the feeder that the kind of prior art adopts is: connect the feed port of the rectangular hopper 20 of conical mixer pot 10, earlier freely fall on a vertical edge of rectangular by the prepared raw material, on the other Two small screws 40 are installed at the right angles of one side, and the two screws are rotated ...

AI Technical Summary

Problems solved by technology

[0004] Due to the screw feeding, there is a huge friction force with the screw sleeve wall, and the resin has a strong viscosity after friction and high-temperature melting, which often sticks or blocks the screw of the feeder, overloading the motor of the feeder. Carrying, the motor is often burned out, which brings great inconvenience and trouble to production;

[0005] Due to the non-stop friction temperature of the two small screws rising above 200 degrees Celsius, the aging point of the resin and rubber is at 160 degrees Celsius, which causes the resin and rubber to age after high temperature, thus greatly reducing the adhesion of the product;

[0006] Due to the different feeding angles, all feeds are fed by screw forced extrusion, the uniformity is extremely poor, and the feeding size is often uneven, resulting in an unbalanced formula ratio in the twin-screw rubber making machine, which seriously affects product stability
