Description

Technical Field

[0001] This utility model relates to a coating liquid heating device for a coating machine. Background Technology

[0002] A coating machine applies a coating liquid or other substance to the surface of fabrics or paper through a coating device, and then dries and stores them, thereby giving the fabrics or paper a certain property to meet specific needs. A common example is that a coating machine is used to give paper a waterproof function.

[0003] However, there are also many problems in the use of the coating machine. For example, the device used to store the coating liquid in the coating machine is a tank. The optimal coating temperature of the coating liquid is about 20°C. In winter, due to the low temperature, the fluidity of the coating liquid becomes worse, resulting in a poorer delivery effect of the coating liquid.

[0004] Our company previously used a heating layer on the outer surface of the tank to heat the coating liquid inside. However, because the coating liquid contains chemical components, the continuous heating of the tank while the coating liquid remained stagnant caused the following problems:

[0005] The first problem is uneven heating, with the center temperature being lower than the surrounding temperature;

[0006] The second problem is that continuous heating will cause changes in the chemical composition of the coating solution, leading to changes in the performance of the coating solution. Utility Model Content

[0007] The purpose of this utility model is to provide a heating device for the coating liquid of a coating machine, solving the problem of uneven heating in the prior art. The specific solution is as follows:

[0008] A coating liquid heating device for a coating machine includes a tank for storing the coating liquid and a circulating heating circuit drawn from the tank;

[0009] The circulating heating circuit includes a second delivery pipe led out from the tank body;

[0010] A support frame is set on the side of the tank, and a circulation pump is installed on the support frame. The second delivery pipe is connected to the inlet of the circulation pump.

[0011] The upper end of the curved pipe is connected to the outlet of the circulating pump, one end of the return pipe is connected to the lower end of the curved pipe, and the other end of the return pipe is connected to the inside of the tank.

[0012] The support frame is also equipped with a heating component for heating the bent tube;

[0013] The circulating pump is used to draw out the coating liquid from the tank and, after being heated by the heating element, deliver it back into the tank.

[0014] Optionally, the heating component includes a pair of heating plates, and the heating plates have a hot water circulation passage inside;

[0015] The heating plate is used to clamp the curved tube from both sides;

[0016] It also includes a protective shell that acts as a enclosure, which is used to surround the heating plate.

[0017] Furthermore, the heating plate is provided with a curved tube placement groove for storing curved tubes, and the outer wall of the curved tube is in contact with the inner wall of the curved tube placement groove.

[0018] Optionally, the heating plate is made of iron-based sheet material.

[0019] The beneficial effects of this utility model are as follows:

[0020] A heating circulation loop is set up on the side of the tank to achieve flow heating of the coating liquid and avoid the problem of uneven heating of the coating liquid;

[0021] To prevent the coating solution from settling;

[0022] This addresses the issue of altered coating liquid properties caused by overheating in a static state, a problem present in existing technologies. Attached Figure Description
