[0025] The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings.

[0026] Example:

[0027] The accompanying drawings show a specific embodiment of the double roller machine roller mechanism of the present invention. Figure 1 It mainly includes a first roller 1 and a second roller 2. Both ends of the first roller 1 and the second roller 2 are respectively provided with a supporting shaft 3.

[0028] The first roller 1 includes a first intermediate straight cylinder section 101 and first conical cylinder sections 102 respectively connected to both ends of the first intermediate straight cylinder section 101. The small end of the first conical cylinder section 102 is connected to the first intermediate straight cylinder section 101. The first intermediate straight cylinder section 101 and the first conical cylinder sections 102 at both ends are integrally formed.

[0029] The second roller 2 includes a second intermediate straight cylinder section 201 and second conical cylinder sections 202 respectively connected to both ends of the second intermediate straight cylinder section 201. The large end of the second conical cylinder section 202 is connected to the second intermediate straight cylinder section 201. The second intermediate straight cylinder section 201 and the second conical cylinder sections 202 at both ends are integrally formed.

[0030] The surfaces of the first cone section 102 and the second cone section 202 on the same side rotate in conjunction with each other. Through the cooperation of the cone sections at both ends, the first roller 1 and the second roller 2 can achieve axial positioning to avoid axial movement.

[0031] The internal structure of the first roller 1 and the second roller 2 is the same. Figure 2 Taking the internal structure of the first roller 1 as an example, a cooling water channel 4 is provided inside the first roller 1. The cooling water channel 4 includes a main channel 401. The inner diameter of the main channel 401 gradually increases from the middle to the two ends. The two ends of the main channel 401 are respectively connected to a water collection groove 402. The water collection grooves 402 at both ends are also connected to a connecting channel 403. The inner diameter of the connecting channel 403 gradually decreases from the inside to the outside and then remains unchanged. The support shafts 3 at both ends are respectively connected to the two connecting channels 403. A first sealing ring 8 is provided between the support shaft 3 and the connecting channel 403 to prevent water leakage. The support shaft 3 is also provided with an inlet and outlet water channel 6 connected to the cooling water channel 4. The cooling water circulates from the support shaft 3 into the interior of the roller.

[0032] Two extension channels 5 connected to the cooling water channel 4 are also provided in the first roller 1. Each extension channel 5 includes a water collection channel 501. Diversion channels 502 are respectively provided between the water collection channel 501 and the main channel 401 and the water collection groove 402. The water collection channel 501 is inclined to facilitate drainage.

[0033] The first cone sections 102 at both ends of the first roller 1 are respectively provided with sealing plugs 7 connected to the two extension channels 5. Figure 3 The specific structure of the sealing plug 7 is that the sealing plug 7 includes a plug rod 701, which is threadedly connected to the water collection channel 501. One end of the plug rod 701 is connected to a plug head 702, which blocks the water collection channel 501. A second sealing ring 9 is also provided in the water collection channel 501. The plug head 702 fits tightly with the second sealing ring 9 to prevent water leakage.

[0034] The two extended channels 5 are closer to the roller surface, which can improve the cooling water's regulating effect on the roller surface temperature. When drainage is needed, just unscrew the sealing plugs 7 at both ends and rotate the roller. The cooling water in the cooling water channel 4 can be discharged through the extended channel 5 and automatically drained. The operation is simple and convenient.

[0035] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included within the scope of protection of the present invention.
