Spray booth double chain conveyor mechanism

Abstract

The invention discloses a double-chain delivery mechanism for a spray booth and aims at overcoming the defects that work-pieces can slide laterally easily during delivery and affect the spray quality due to poor limit reliability of supports of prior ground chain structure supporting skids; ground chains are prone to loose and affect the chain transmission after the long-time operation; supports are prone to deformation due to the gravity action of work-pieces and affect the skid steady operation. The mechanism comprises two opposite chain transmission delivery frames. Each chain transmission delivery frame comprises a base and a chain mounting casing. Transmission chains are arranged in the chain mounting casing, connection supports are connected onto the transmission chains, limit bends bend upwards are arranged at the end edges of the horizontal planes of the supports, limit protrusions are arranged at the other opposite edges of the horizontal planes of the supports, and the skids are clamped between the limit bends and the limit protrusions. Supporting retaining plates are connected with the upper ends of the chain mounting casings, and buffering universal wheels are connected with the supports and are supported on the supporting retaining plates.

Description

technical field [0001] The invention relates to a conveying structure, more specifically, it relates to a double-chain conveying mechanism for a painting booth with stable transmission. Background technique [0002] At present, most of the spray booths adopt the transmission mode of ground chain, and the transmission of workpieces is realized through the transmission of ground chain. The usual structure is to connect the bracket on the ground chain, the skid is supported on the upper end of the bracket, the workpiece is supported on the skid, and the transmission of the chain drives the movement of the skid. The stability of the ground chain transmission directly affects the stability of the workpiece transmission. Now many ground chain brackets have poor limit reliability, and the skid is easy to slide left and right on the bracket, which causes the distance between the spraying robot and the workpiece to change, causing the spraying flow. Problems such as hanging and insu...

AI Technical Summary

Problems solved by technology

[0004] The present invention overcomes the deficiencies in three aspects of the existing ground chain structure: firstly, the position limit reliability of the bracket supporting the skid is poor, and the workpiece is easy to slide left and right during the conveying process, which affects the spraying quality; It is prone to slack and affects the transmission of the chain; third, the bracket is prone to deformation due to the gravity of the workpiece for a long time, which affects the smooth operation of the skid
