Blocking device for low space

Abstract

A blocking device for a low space comprises a push rod assembly connected to a bottom plate, a guide block assembly is connected to the push rod assembly, and a blocking assembly is connected to the guide block assembly; the blocking assembly comprises polyurethane and a baffle, the polyurethane and the baffle are connected to the upper portion of a blocking plate, the lower portion of the blocking plate is connected to the upper portion of a swing arm, the lower portion of the front end of the swing arm is matched with the push rod assembly, the rear end of the swing arm is connected to a swing arm support, and the swing arm support is connected to the bottom plate. The push rod assembly comprises a push rod which is fixed to the bottom plate through a push rod fixing base and connected with the middle of a transmission shaft, the transmission shaft is connected to the guide block assembly, and follow-up bearings are connected to the two ends of the transmission shaft and make contact with the lower portion of the swing arm. The guide block assembly comprises a guide block, the guide block is connected to the bottom plate, a guide bearing is arranged on the guide block, and the transmission shaft is sleeved with the guide bearing; the space occupation in the height direction is reduced, and large horizontal force and impact force can be borne; installation is simple and fast, and universality is high.

Description

technical field [0001] The invention belongs to the technical field of conveying lines, and in particular relates to a blocking device for low space. Background technique [0002] The blocking device used in the field of the existing conveyor line (China Patent Application No. 201922435305.6, named: A pneumatic blocker for conveyor), its structure is a cylinder plus two guide rods, the working principle is that the cylinder extends, However, its disadvantages are: it occupies a large space in the vertical direction, and it is difficult to withstand a large horizontal impact force. Even if it can withstand a relatively large horizontal impact force, many devices need to be added to achieve it; in addition, in the case of long-term large impact force The service life will also be greatly shortened and other defects. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a b...
