[0002] Soft polyurethane is mainly a linear structure with thermoplasticity. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, has smaller compression deformation, and has good heat insulation, sound insulation, earthquake resistance and anti-toxic properties. Therefore, it is used as packaging, sound insulation and filtration materials.

[0003] For example, Chinese patent CN216917455U discloses a heat dissipation mechanism for a polyurethane wear-resistant roller. The device drives the outlet pipe and the infrared thermometer on the connecting block to move when the threaded rod rotates. When the infrared thermometer detects that the surface temperature of the polyurethane roller body is too high, the signal is transmitted to the controller, and the controller opens the control valve to spray dry ice gas from the outlet pipe to the polyurethane roller body and the conveyor belt to cool down, thereby effectively preventing the polyurethane roller body and the conveyor belt from frictional heating, which leads to poor wear resistance.

[0004] However, there are certain defects in this patent. The device cools down the side walls of the polyurethane roller body by spraying dry ice to the bottom of the polyurethane roller body. However, the dry ice is always sprayed to the bottom of the polyurethane roller body, which will cause uneven heat dissipation at different positions of the polyurethane roller body.

The two support legs 2 are symmetrically arranged relative to the middle surface of the fixing plate 1 in the left and right directions. The support legs 2 can support the position of the entire device.

[0031] and a processing assembly 4 disposed on the side wall of the fixed plate 1;

[0032] The processing assembly 4 includes an adjustment mechanism 41 installed at a side wall position of the fixed plate 1;

[0033] A heat dissipation mechanism 42 is installed at the top of the fixing plate 1 , and one end of the heat dissipation mechanism 42 is connected to one end of the adjustment mechanism 41 .

[0034] The adjusting mechanism 41 includes a support frame 418 and a limiting rod 4111. The support frame 418 is fixedly installed on the side wall of the column 3. A motor 417 is fixedly installed on the top of the support frame 418. The motor 417 is installed with a reciprocating screw rod 4110 through the rotating shaft transmission at the output end. The other end of the reciprocating screw rod 4110 movably passes through the inner wall of the column 3 and extends to the inner wall of the column 3. The motor 417 is installed with a belt 419 through the rotating shaft transmission at the output end. The other end of the belt 419 is installed with a connecting rod 413. One end of the connecting rod 413 is rotatably connected to the side wall of the column 3 through a bearing, and the other end of the connecting rod 413 is fixedly installed with a limiting block 412. A driving gear 411 is slidably installed on the side wall of the connecting rod 413. A driven gear 414 is contacted with the side wall of the driving gear 411. A rotating rod 415 is fixedly installed on the inner wall of the driven gear 414. The side wall of the rotating rod 415 is rotatably connected to the inner wall of the column 3.

[0035] In this embodiment, both ends of the limiting rod 4111 are fixedly connected to the inner wall of the column 3 , and the limiting rod 4111 is located at the bottom position of the reciprocating screw rod 4110 .

[0036] Furthermore, a polyurethane wear-resistant roller body 416 is fixedly mounted on the side wall of the rotating rod 415 , and the polyurethane wear-resistant roller bodies 416 are equidistantly distributed on the side wall of the rotating rod 415 .

[0037] Example 2

[0038] On the basis of Example 1, a preferred embodiment of a heat dissipation mechanism for a polyurethane wear-resistant roller provided by the utility model is as follows: Figures 1 to 5 As shown: the heat dissipation mechanism 42 includes a second support frame 421, the second support frame 421 is fixedly installed on the side wall of the column 3, a dry ice blasting device 422 is fixedly installed on the top of the second support frame 421, a transport pipe 423 is fixedly installed on the output end of the dry ice blasting device 422, an air outlet pipe 424 is fixedly installed on the other end of the transport pipe 423, and a base 425 is fixedly installed on the bottom of the air outlet pipe 424.

[0040] In the specific implementation process, when the operator uses the device, the position of the device is first supported by the support legs 2 at the bottom of the device. When the surface of the polyurethane wear-resistant roller body 416 needs to be cooled, the operator can directly push the position of the driving gear 411, and the driving gear 411 slides on the surface of the connecting rod 413. After the connecting rod 413 slides, the side wall of the driving gear 411 will mesh with the driven gear 414. Then the operator can directly turn on the motor 417, and the motor 417 drives the belt 419 and the reciprocating screw 4110 to rotate through the rotating shaft at the output end. When the reciprocating screw rod 4110 rotates, it will drive the base 425 to move back and forth, the belt 419 will drive the position of the connecting rod 413 to rotate, and the connecting rod 413 will drive the position of the driving gear 411 to rotate. At this time, the driving gear 411 and the driven gear 414 are meshed. Therefore, when the driving gear 411 rotates, it can drive the position of the driven gear 414 and the rotating rod 415 to rotate, and the position of the polyurethane wear-resistant roller body 416 is further driven to rotate through the rotating rod 415. At this time, when the outlet pipe 424 is working, it will evenly dissipate heat at different positions on the surface of the polyurethane wear-resistant roller body 416.
