[0019] Embodiment 1

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3, the present utility model provides a technical solution: when the hot press roll is working, the hot press roll rotates relative to another pressure roll to form a nip. When the material passes through the nip, it is heated and pressured by the hot press roll, thereby realizing the compounding, flattening or shaping of the material. The magnitude of the pressure is usually controlled by adjusting the distance between the two pressure rolls, which can be achieved through the adjustment of an eccentric mechanism, a worm and worm gear or a hydraulic system. A hot press roll device for fiber layer composite processing includes a roll body 100. At both ends of the roll body 100, there are roll shaft mounting rods 101. Inside the roll body 100, there is a hollow hot press oil cavity groove 102. At both inner ends of the roll body 100, there are also heating grooves 207. At both ends of the roll body 100, there are also mounted hot press mounting ring seats 200. On one side of the hot press mounting ring seat 200, there is a hot press resistance wire 202. The outside of the hot press resistance wire 202 is sleeved and fixed with a mica sleeve 201. One end of the mica sleeve 201 is fixedly installed with a rotary contact head 300. On one side of the hot press mounting ring seat 200, there is fixedly installed a hot press connection seat 204. When using the hot press roll in this application to perform composite processing on the fiber layer, the heating component in this application is modularly designed, and the heating structure and the roll body 100 are detachable structures. When in use, take out the hot press mounting ring seat 200, align and insert the mica sleeve 201 on the hot press mounting ring seat 200 into the heating grooves 207 on both sides of the roll body 100, and align the alignment holes 205 on the hot press mounting ring seat 200 with the roll shaft mounting rods 101 at both ends of the roll body 100. After insertion and alignment, use bolts to install them into the threaded assembly holes 203, thereby fixing the hot press mounting ring seat 200 at both ends of the roll body 100. And during operation, the hot press resistance wire 202 converts electrical energy into heat energy and conducts it to the surface of the roll body 100. At the same time, the roll body 100 will also heat the oil in the hot press oil cavity groove 102 during the heating process. The heated hot press oil cavity groove 102 can better ensure the uniform heating of the surface of the roll body 100. During the use of this device, through the detachable modular design, it is convenient for overhaul and maintenance, easy to maintain, and at the same time improves the practicability and convenience of this device.

[0021] Specifically, the hot pressing resistor wire 202 and the hot pressing mounting ring seat 200 are fixedly installed by means of a rotating contact 300 to ensure the stability of the hot pressing resistor wire 202 after installation. A threaded assembly hole 203 is provided on the surface of the hot pressing mounting ring seat 200. The hot pressing mounting ring seat 200 and the roller body 100 are fixedly installed by bolts penetrating the threaded assembly hole 203. While providing a more stable installation, a sealing gasket 206 is also bonded and installed on one side of the hot pressing mounting ring seat 200. The hot pressing mounting ring seat 200 and the roller body 100 are sealed by the sealing gasket 206 during installation to ensure the sealing after installation and prevent dust and water stains from entering the heating tank 207 during operation. The mica sleeve 201 is aligned with the heating tank 207 and installed. After installation, the mica sleeve 201 fits against the inner wall of the heating tank 207 for better heat conduction.

[0022] Example 2

During use, if a single hot pressing resistor wire 202 is damaged, it can be disassembled by rotating the contact head 300 and the hot pressing seat 204. When rotating, the rotating contact head 300 is connected to the conductive contact piece 301 through the conductive contact piece 301. The elastic contact seat 304 is squeezed into contact to ensure a stable connection. The screw-on structure can facilitate the individual replacement of damaged thermocompression resistor wires 202, thereby improving the convenience of replacement and the practicality of the device. Specifically, the rotary contact 300 is screwed onto the thermocompression connector 204 through the screw-on groove 302. At the same time, after the rotary contact 300 is screwed, it contacts the elastic contact seat 304 through the conductive contact piece 301. The contacting conductive contact piece 301 and the elastic contact seat 304 can ensure electrical conductivity, so that the thermocompression resistor wire 202 can convert electrical energy into thermal energy for thermocompression work when working.
