Non-return device for waste material sliding groove

Abstract

The invention discloses a non-return device for a waste material sliding groove. The non-return device comprises the waste material sliding groove, a telescoping mechanism and a rotating mechanism, wherein an opening is formed in the side wall of the waste material sliding groove; the rotating mechanism comprises a non-return block, a pin seat and a hinge pin; the non-return block is provided with a triangular point; one surface of the point is a guide oblique surface, and the other surface of the point is a right-angle surface; the non-return block is rotatably connected with the pin seat through the hinge pin; the pin seat is fixedly mounted on the outer side wall of the waste material sliding groove; the telescoping mechanism comprises a non-return frame, a spring push rod and a spring; the spring push rod is mounted in the non-return frame in a sliding manner; the spring is arranged on the spring push rod in a sleeving manner; one end of the spring is connected with the spring push rod, and the other end of the spring is connected with the non-return frame; the non-return frame is fixedly mounted on the outer side wall of the waste material sliding groove; and the spring push rod pushes the non-return block to rotate in or out of the opening under the action of the spring. The non-return device can prevent waste material blocks in the sliding groove from sliding backwards, can be effectively implemented for a long time, and is convenient to maintain.

Description

technical field [0001] The invention specifically relates to a non-return device for waste chutes, which is suitable for all pushing equipment with chutes, especially for waste pushing equipment with chutes. Background technique [0002] According to the different strip width requirements of customers, there will be trimming function in the cold rolling process. There are two methods of waste edge processing on the continuous unwinding line: one is the waste edge coiling method, and the waste edge is rolled into a ball through a set of small winding mandrels, and then the mandrel shrinks to push the waste edge roll away; the other is The first is the crushed edge extrusion method. The waste edge is cut into pieces by the waste edge extruder and extruded into pieces in the bin, and then the extruded waste block is pushed out of the bin body and transported to the waste hopper through the chute for transport. Since the third cold rolling continuous annealing line has a large ...

AI Technical Summary

Problems solved by technology

Due to the relatively heavy actual production tasks and the relatively harsh on-site environment, the stopper at the entrance of the chute channel is easily worn or buried by the accumulated iron debris, so that it cannot prevent the waste block from slipping backwards, resulting in waste extrusion The door of the machine compartment cannot be closed, resulting in the failure of the equipment to squeeze the waste edge normally, resulting in a fault alarm and shutdown affecting production
