A chemical coil dip coating device

Abstract

The invention belongs to the field of chemical product processing and particularly relates to a chemical coiled material dip coating device which comprises fetal substrate fabric, a material tank, feeding modules, guide rollers, tensioning rollers, lifting mechanisms, a thickness-adjusting roller couple and a cooling module, wherein each of the feeding modules comprises a shell, landing legs, feeding gears, extrusion rollers and a filter screen; the landing legs are fixed with the position above the bottom of the material tank; the shells and the landing legs are fixed above the landing legs; the symmetrical feeding gears are arranged in each shell, are meshed with each other, and are in seal connection with the corresponding shell through shafts; a plurality of extrusion rollers are arranged between each of the feeding gears and the corresponding shell; and the heat conductive filter screen is arranged at the lower part of the shell. The chemical coiled material dip coating device adopts the heat conductive filter screens, heating blocks and the heat conductive extrusion rollers to rapidly heat coating in the feeding modules so as to shorten the preheating time of coating; in addition, the filter screens and the extrusion rollers are adopted to extrude and smash small particulate matters to prevent the situation that the small particulate matters scratch the fetal substrate fabric, so that the product quality is improved.

Description

technical field [0001] The invention belongs to the field of chemical product processing, in particular to a dip coating device for chemical coils. Background technique [0002] A common dip-coating processing device for waterproof coils includes a material pool, which is filled with paint, and coils are arranged on the side walls around the paint, and heat-conducting oil is passed through the coils to heat to form a heated material pool. There are multiple impregnating rollers in the pool to squeeze the tire base cloth. The impregnating rollers are soaked in the paint, and the impregnating rollers are connected with the lifting mechanism. There are multiple guide rollers above the material pool. After passing through the guide roller and the impregnating roller, it enters the forming thickening roller composed of the upper forming thickening roller and the lower forming thickening roller. After the thickness is adjusted, it leaves the material pool and enters the next proce...

AI Technical Summary

Problems solved by technology

This technical scheme realizes the automatic feeding of tire base cloth, but this technical scheme still has the following defects: the technical scheme transports the paint to the surface of the upper belt material roller through the material transfer roller, and the efficiency is low; The cloth transports the paint located on the lower side of the base fabric to the trough, and the upper side of the base fabric can be coated only after the trough is full, resulting in uneven coating on both sides of the base fabric and a decline in the quality of the finished base fabric
