Spiral forced feeding device

Abstract

The invention relates to a spiral forced feeding device. The spiral forced feeding device comprises a material conveying barrel, a material conveying screw, a material conveying motor, a material storage hopper, a material falling barrel, a propulsion motor, a propulsion shaft, a spiral propulsion blade and an anti-bridging shaft, wherein the material conveying screw is mounted in the material conveying barrel; the material conveying motor is in transmission connection with the material conveying screw; a charging opening is formed in a barrel body of the material conveying barrel; a material falling opening of the material storage hoper is communicated and connected with the charging opening through the material falling barrel; the upper end of the propulsion shaft is rotatably mounted at the top of the material storage hopper; the propulsion shaft is positioned in the material storage hopper, and the lower end of the propulsion shaft extends to the charging opening; the propulsion motor is in transmission connection with the propulsion shaft; the spiral propulsion blade is mounted at the lower part of the propulsion shaft; the upper part of the spiral propulsion blade is positioned in the material storage hopper, and the lower part of the spiral propulsion blade is positioned in the material falling barrel; the anti-bridging shaft is mounted at the upper part of the propulsion shaft.

Description

technical field [0001] The invention relates to a feeding device, in particular to a screw forced feeding device. Background technique [0002] The feeding device of the current sheet extruder generally includes a feeding barrel, a feeding screw, a feeding motor and a storage funnel. The feeding screw is installed in the feeding barrel, and the feeding screw is in close contact with the inner wall of the feeding barrel. One end is transmission-connected, and the body of the feeding cylinder is provided with a feed port, and the discharge port of the storage funnel communicates with the feed port. The plastic granules in the storage funnel fall into the feeding barrel by their own gravity, and under the push of the feeding screw, the plastic granules are sent out from one end of the feeding barrel to complete the feeding of the sheet extruder. [0003] However, with the advancement of extrusion technology and technology, as well as the control of production costs, waste recy...

AI Technical Summary

Problems solved by technology

Because the recycled materials are rough, irregular in shape and large in particle size, and in order to prevent the feeding screw from arching the plastic upward into the storage funnel, the feeding port of the feeding cylinder is generally designed to be small, so that the recycled materials often get stuck. Bridging occurs at the connection between the feeding cylinder and the storage funnel, causing blockage, which leads to a shortage of material in the sheet extruder, and must be shut down for cleaning and maintenance, which affects the smooth progress of production and reduces production efficiency.
