Description

TECHNICAL FIELD

[0002] In the plate processing, composite material manufacturing, rubber vulcanization and other industries, materials often need to be heated and pressed to achieve specific physical or chemical changes, so as to obtain the required product performance. The hot pressing plate, as a key processing equipment, can provide uniform heating and stable pressure to meet the production needs of these industries. The temperature uniformity of the traditional hot pressing plate is difficult to guarantee. When heating different specifications and different materials, local temperature may be too high or too low, which not only affects the quality of the product, but also may cause deformation, cracking and other adverse consequences of the material due to uneven heating. Therefore, there is an urgent need for a layered hot pressing plate structure in the market.

[0033] The clamping mechanism 2 comprises a round groove 22 opened on one side of the heat insulation frame 1, the inside of the round groove 22 is provided with a clamping ring 23 and a fixed ring 26, the size of the fixed ring 26 and the clamping ring 23 is the same, the end opposite to the fixed ring 26 and the clamping ring 23 is provided with a spring 24, the inner surface of the spring 24 is in close contact with the outer surface of the clamping rod 21, the inside of the round groove 22 is fixedly connected with the clamping ring 23, the inside of the round groove 22 is slidably connected with the fixed ring 26, the fixed ring 26 and the clamping ring 23 are slidably connected with the clamping rod 21, and one side of the processing plate 4 is provided with a clamping groove 14 matched with the clamping rod 21.

[0034] The two sides of the clamping rod 21 opposite to each other are welded with pull rings 25, and the two pull rings 25 are the same in size and are mirror image distributed.

[0035] The lower inner wall of the hot pressing plate body 16 is provided with a heating pipe 15, the heating pipe 15 is in a wave shape, which is convenient to improve the uniformity of heating, the two ends of the heating pipe 15 penetrate through the hot pressing plate body 16 and the heat insulation frame 1 and extend to the outside of the heat insulation frame 1, the two sides of the heating pipe 15 outside the heat insulation frame 1 are fixedly provided with connecting heads 11, the heating pipe 15 can be connected with an external power source through the connecting heads 11, and the current passes through the heating pipe 15 to make it heat.

[0036] Working principle: first, the processing plate 4 is placed on the hot pressing plate body 16, the positioning strip 13 at the bottom of the processing plate 4 is matched with the positioning groove 12 at the top end of the hot pressing plate body 16, which ensures that the processing plate 4 is accurately installed on the hot pressing plate body 16 and prevents lateral movement during subsequent work.
