Security inspection machine and its conveying device

Abstract

Provided are a conveying apparatus (100) and a security-check machine using said conveying apparatus (100), comprising a belt (15) used for transmitting items, a support frame (20) for supporting the belt (15), a driving cylinder (13) for driving the belt (15) to rotate, and a driven cylinder (12) fitting with the driving cylinder (13) and supporting the belt (15); the driven cylinder (12) and the driving cylinder (13) are arranged on the two ends of the support frame (20), respectively; the support frame (20) comprises a plurality of rectangular profiled materials (21) joined and connected together. The plurality of rectangular profiled materials (21) are arranged and the plurality of rectangular profiled materials (21) are joined to form the support frame (20), and assembly is convenient; rectangular profiled materials (21) are used for joining and the fabrication of the structures of each of the rectangular profiled materials (21) is the same; thus major errors in machining can be avoided, and the two ends of the support frame (20) are guaranteed to be parallel, thereby preventing the problem of the belt (15) running toward one side when in operation.

Description

technical field [0001] The invention belongs to the field of security inspection equipment, and in particular relates to a conveying device used in a security inspection machine and a security inspection machine using the conveying device. Background technique [0002] The conveying device of the security inspection machine generally includes a conveyor belt, a bracket supporting the conveyor belt, and a roller that drives the conveyor belt to rotate. The brackets in the conveying device of the current security inspection machine are generally formed by laser cutting sheet metal, bending, and then welding strong ribs. The various mounting flange positions of the bracket are usually processed according to the drawings during the laser cutting process, and then bent and welded to be positioned on the overall bracket. Due to the large tolerance of sheet metal bending, deformation will occur during bending and welding, and after welding, sheet metal parts will continue to produ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a conveying device, aiming to solve the problem that the conveying device in the existing security inspection machine has a large deviation and deformation during manufacture, which will cause the two ends of the conveying device to be non-parallel, and the belt will deviate when it is working. question
