At present, the special coater for waterproof zipper coating is equipped with a feed wheel at the front side of the coating head platform, a coating mechanism at the upper end of the coating head station, a hot air box placed at the front side of the coating mechanism, a guide roller at the inner side of the hot air box, at least four groups of hot air fans on the top plate of the hot air box, a hot air box at the middle of the top plate of the hot air box, a waste gas discharge channel, and the outside of the discharge wheel is wound, The end of the fiber mesh passes through the feed wheel and the coating mechanism. Now, the operating principle of circulation is used. In the existing photoresist supply system and coating machine, when the photoresist flow in the pipeline overheats the exchange device, the heat is exchanged between the photoresist and the heat exchange device, so that the temperature of the photoresist rises. The photoresist adhesive supply system, the photoresist participating in the heat exchange, is heated by the heat exchange device, It increases the heat exchange area between the photoresist and the heat source, ensures the temperature rise effect of the photoresist, improves the temperature treatment efficiency of the photoresist, shortens the temperature treatment time of the photoresist, and improves the productivity. The coil of the new coater known at present can be output through the tail end of the hot drying channel during the coil conveying process, which makes the coater more compact, which makes the new coater take up less space. Due to the curling setting of the hot drying channel, the coater takes up less space. The coater can be equipped with a shell, which covers the whole hot drying channel, and the shell separates the external air, Make the thermal drying tunnel in a relatively closed space, so that the heat of the thermal drying tunnel is not easy to lose. Because the new coating machine is more energy-saving, in the current field of PCB manufacturing, especially in the vertical arm coating machine clamp and coating method, by changing the shape of the pinion into a rectangle, the wear of the contact surface is reduced and the life of the clamp is extended. The improved pinion is not easy to accumulate ink, and the occurrence rate of ink accumulation is greatly reduced.
