What problems can be solved by the base material deviation prevention device of coater oven
Due to the special coating machine for waterproof zipper coating, there is a feed wheel at the front of the coating head platform, a coating mechanism at the upper end of the coating head platform, a hot air hood at the front, a guide roller at the inner side of the coating mechanism, at least four groups of hot air fans at the top plate of the hot air box, an exhaust emission channel at the middle part of the top plate of the hot air box, and the end of the winding material outside the discharge wheel passes through the feed wheel and the coating mechanism, It is wound on the outer periphery and the surface of the guide roller in the hot air box.
A coating machine that automatically adjusts the surface density of the coating, including a densitometer for measuring the surface density, one end of the densitometer is electrically connected to the control cabinet of the coating machine, the end of the densitometer, the screw pump motor servo control valve block and the adjusting screw are electrically connected, the coating machine control cabinet is respectively connected to the screw pump motor servo control valve, and the servo control valve block is arranged above the coating nozzle, The adjusting screw is used to adjust the distance between the coating nozzle and the rear roll.
Now, through the connection between components, a new closed loop control system has been formed, and automatic monitoring is used to adjust the surface density of the substrate spray, thus solving the problems of manual monitoring and manual monitoring and calculation. In the existing technology, the adjustment of the surface density is low in accuracy and adjustment. Now there are new wheels with a heat dissipation structure, including the wheel core of the wheel body, multiple baffle fins, and the outer wall of the wheel core, It also has a good heat dissipation effect by blocking the fins connected to the inner wall of the wheel body.
