Automatic roller coating machine for mining PVC pipe conductive carbon black

Abstract

The invention discloses an automatic roller coating machine for mining PVC pipe conductive carbon black. The machine comprises a base, a working plate, a working hole, a bearing, a rotating mechanism, a shaft sleeve, a gear disc, a driving motor, a coating device, a dowel pin, a spring, a crank mechanism, a roller, a spraying device, a spraying pipe, a valve, a liquid pump, a rotating handle, a connecting rod, a rolling shaft and a nozzle. The automatic roller coating machine for the mining PVC pipe conductive carbon black has the following beneficial effects that a plastic extruding machine continuously extrudes out PVC pipes; then, the roller coating work of the PVC pipes is completed through the continuously rotating roller and continuously sprayed paint in the extruding engineering; and as the machinery replaces the manual spraying mode, the nonuniform spraying condition is effectively prevented, and the health of workers is effectively protected.

Description

technical field [0001] The invention relates to an automatic roll coater for PVC pipes, in particular to an automatic roll coater for PVC pipe conductive carbon black used in mines. Background technique [0002] Due to the existence of gas and other flammable gases in underground mines, PVC mainly uses polyvinyl chloride as the main raw material, and is mainly used for underground gas drainage, ventilation, drainage, and spraying by coating an appropriate amount of auxiliary agents such as flame retardant and antistatic. etc. Generally, conductive carbon black is sprayed on the surface of PVC pipes to increase the performance of PVC pipes. At present, the surface spraying of PVC pipes in production is manual spraying. High, due to the volatilization of paint, the health of human body is affected and the area of ​​spraying is easy to be missed, so the present invention proposes a solution in order to solve this problem. Contents of the invention [0003] The object of the ...
