A spreader and method for automatic spraying of idlers

Abstract

The invention relates to a carrier roller processing device and method, in particular to a lifting appliance and method for automatic carrier roller spray coating. The lifting appliance and method solve the technical problem of automatic carrier roller skin spray coating hanging. The lifting appliance comprises a U-shaped shifting fork opened and closed pneumatically, a lifting rod spring piece base, a gravity conical blocking rod, a spring hanging plate fixing sleeve, two spring hanging plates, a spring hanging plate opening and closing base and the like. The method comprises the steps that a coating hanging chain is made to run to a specific position according to a set trail and is stopped; a carrier roller assembly and disassembly mechanical arm clamps a coating carrier roller and enables the coating carrier roller to move to the position of the axis of the lifting appliance and then the coating carrier roller moves upwards; the U-shaped shifting fork opened and closed pneumatically moves towards the left to be connected with the spring hanging plate opening and closing base in a clamping mode and lift the spring hanging plate opening and closing base, and at the moment, external hooks at the lower ends of the spring hanging plates enter the lower face of the bottom of a bearing seat; then the U-shaped shifting fork opened and closed pneumatically moves downwards, and the spring hanging plate opening and closing base also moves downwards to unfold the spring hanging plates, the external hooks on the lower portions of the spring hanging plates expand outwards to enable the lower face of the bottom of the carrier roller bearing seat to be supported and hung. The device and method are high in automation degree, high in efficiency and capable of saving working hours.

Description

technical field [0001] The invention relates to a processing device and method for idler rollers, in particular to a spreader and method for automatic spraying of idler rollers. Background technique [0002] Idler rollers are the load-bearing parts of belt conveyors and other conveying machinery. There are a large number of them. During the manufacturing process, in order to achieve anti-rust, aesthetics or other special functions, they need to be sprayed. The existing problem is that the current domestic idler spraying equipment and technology are relatively backward, basically a semi-mechanized spraying line, loading and unloading the idler on the hanging chain spreader is done manually, the labor intensity is high, the labor efficiency is low, and the cost of working hours is high. The key to realize the fully automatic spraying of idler rollers is to solve the hanging technology for automatic spraying of idler rollers or idler roll skins. Contents of the invention [...
