Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a coating device for an adhesive. Background Art

[0002] The function of the coating machine is to coat the polymer adhesive on the substrate of the workpiece, cure it by heating, and form a composite board after laminating it with the cover board or film by roller pressing. The viscosity of the adhesive is greatly affected by temperature, and the production plant where the coating is carried out is large, and temperature differences are prone to occur between morning and evening and between winter and summer, resulting in large fluctuations in the viscosity of the adhesive. The coating machine is prone to uneven coating during coating, which in turn leads to large fluctuations in the coating effect, unstable product quality, and in severe cases, unqualified products, resulting in a reduced product qualification rate.

[0003] After searching, a Chinese patent publication number CN217615644U discloses a constant temperature coating device for a metal composite plate adhesive, including a material tray, which is a semi-cylindrical sandwich structure, the material tray including an inner wall and an outer wall of the material tray, a thermal insulation interlayer is formed between the inner wall and the outer wall of the material tray, and the thermal insulation interlayer is connected to a constant temperature water circulation system; an adhesive barrel is provided below the material tray, and an adhesive coating system is provided above the material tray; the bottom end of the material tray is connected to the adhesive barrel through a feed pipe, the top end of the feed pipe passes through the thermal insulation interlayer and is connected to the semi-cylindrical inner cavity of the material tray, the upper part of the material tray is connected to a return pipe, one end of the return pipe is connected to the inner cavity of the material tray, and the other end is connected to the adhesive barrel, and a feed pump is connected to the feed pipe. The device can effectively ensure that the temperature of the adhesive is constant, the viscosity is stable, and the coating is uniform, so that the quality stability of the produced metal composite plate is improved. However, compared with the prior art, the temperature of the adhesive drops after it leaves the barrel and before it is coated, which affects the bonding effect of the adhesive and causes the coating effect to deteriorate. The practicality of the device needs to be improved. Utility Model Content
