[0024] The tops of both the support seat 1 and the support seat 2 14 are fixed with a support rod 9, which is fixedly connected to the shielding cover 7, and the bottom of the shielding cover 7 is fixedly connected with a dense curtain 6.

Through the setting of the counterweight, the dense curtain 6 can maintain a vertical state when in use, which is convenient for the dense curtain 6 to block debris.

[0026] The utility model provides a pressure device for a rubber roller grinding machine, comprising a rubber roller clamping structure 1 and a rubber roller clamping structure 2, wherein the rubber roller clamping structure 1 comprises two first rotating blocks 3, one of which is fixedly connected to a first rotating rod 12, and the other first rotating block 3 is movably connected to a second rotating rod 11, and when the first rotating rod 12 rotates, the rubber roller clamping structure 1 can rotate.

[0028] The dense curtain 6 is composed of a plurality of strip-shaped door curtains that are in contact with each other, and the material of the dense curtain can be wear-resistant cloth.

[0029] The other ends of the first rotating block 3 and the second rotating block 10 are both fixedly connected to a hydraulic telescopic rod 15, and the other end of the hydraulic telescopic rod 15 is fixedly connected to a moving block 8. Under the action of the hydraulic telescopic rod 15, the distance between the moving block 8 and the first rotating block 3 or the second rotating block 10 can be changed.

[0030] A hydraulic telescopic rod 24 is movably connected in the inner cavity of the moving block 8, and the other end of the hydraulic telescopic rod 24 is fixedly connected to a clamping sleeve 19 adapted to the rubber roller.

[0032] It can be seen from the above description that when the device is in use, the rubber roller can be replaced during the rubber roller grinding process, and the dense curtain and the shielding cover 7 can intercept the grinding debris to prevent the debris from splashing everywhere.

[0033] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods.

The hydraulic telescopic rods 24 drive the clamping sleeve 19 to be sleeved on the end of the rubber roller, and the clamping sleeve 19 can clamp the rubber roller to fix the rubber roller. The rotating motor adapted to the above-mentioned rubber roller clamping structure is started, and the rotating motor is used to drive the above-mentioned rubber roller clamping structure to rotate until the above-mentioned rubber roller clamping structure is changed from a horizontal state to a vertical state. At this time, the rubber roller is moved to the side of the dense curtain 6 away from the rubber roller support plate 5. The height of the rubber roller can be changed by extending and retracting the hydraulic telescopic rod 15, so that the pressure between the rubber roller and the grinding tool can be changed during the grinding process, thereby realizing the grinding pressurizing operation. And during the grinding process of the rubber roller, the shielding hood 7 and the dense curtain can shield the grinding debris, and the staff can use another rubber roller clamping structure to clamp and fix another rubber roller to be grinded. When the rubber roller needs to be replaced, the grinded rubber roller is moved back to the rubber roller support plate 5 under the action of the matching rotating motor, and the rubber roller to be grinded is moved to the grinding position under the action of the matching rotating motor, so as to realize the rapid replacement of the rubber roller.
