[0002] The hot pressing plate of the laminating machine is very important in improving temperature uniformity. In the manufacturing process of laminated boards, hot pressing is an important link. Through the action of high temperature and high pressure, raw materials such as resin and fiber are fused and formed within a certain period of time, thus obtaining laminated boards with certain strength and performance.

[0003] The internal flow channel structure of the existing hot plate structure is a single-channel structure, and the heat transfer oil enters from one side and exits from the other side. Because the heat of the heat transfer oil will be absorbed, there will be a temperature difference between the inlet and outlet of the heat transfer oil, which makes the temperature uniformity of the entire hot plate surface worse. Therefore, those skilled in the art provide a laminator hot pressing plate structure with improved temperature uniformity to solve the problems raised in the above background technology.

[0006] Through the above technical scheme, the design of the first flow channel and the second flow channel allows the heat transfer oil to circulate inside the hot plate, thereby transferring heat to the entire surface of the hot plate more evenly. The setting of the first heat transfer oil inlet and the second heat transfer oil outlet can ensure the continuous circulation and conduction of heat, so that the convection mode on both sides can offset the temperature difference of the oil temperatures of the first heat transfer oil inlet, the second heat transfer oil inlet, the first heat transfer oil outlet and the second heat transfer oil outlet, thereby improving the temperature uniformity of the hot plate surface.

[0007] Furthermore, the first flow channel and the second flow channel are arranged in parallel;

[0008] Through the above technical solution, the heat exchange efficiency of the hot pressing plate is improved, thereby improving the temperature uniformity of the hot pressing plate.

[0009] Further, the first flow channel and the second flow channel are both S-shaped;

[0010] The above technical solutions can help to distribute the temperature more evenly during the lamination process and improve the quality and consistency of the product.
