[0033] The pressure roller assembly is driven by a pressure roller drive device to press or release the rubber block, which is more efficient than manually controlling the pressure roller to press or release the rubber block.

[0034] like Figures 6-7 As shown, the pressure roller mechanism 3 also includes a guide assembly, which includes a pressure roller guide rod 30 and a sliding sleeve 31. The sliding sleeve 31 is mounted on the pressure roller bracket 32. The pressure roller guide rod 30 is arranged parallel to the movement direction of the pressure roller assembly and is slidably connected within the sliding sleeve 31. One end of the pressure roller guide rod 30 near the output end of the pressure roller drive device is connected to the pressure roller assembly. Preferably, there are four guide assemblies, respectively arranged around the pressure roller drive device. This arrangement helps to limit the movement direction of the pressure roller assembly and improves the stability of its movement.

[0035] By electrically connecting the controller to the conveying mechanism, pressure roller drive device and slicing mechanism, the rubber cutting process can be automated, which is conducive to further improving the rubber cutting efficiency.

[0036] The operating process is as follows: The controller activates conveyor mechanism 2 to transport the rubber block. The conveying distance and speed can be set by the controller according to actual conditions. When the rubber block reaches the corresponding position of the pressure roller assembly, the controller pauses conveyor mechanism 2 and then activates the pressure roller drive device to extend the pressure roller assembly and press down on the rubber block. Next, the controller activates slicing mechanism 4 to slice the rubber block. After slicing, the controller closes slicing mechanism 4, then retracts the pressure roller assembly. The controller then activates conveyor mechanism 2 again to move the sliced ​​rubber sheet to the discharge hopper. Finally, the slices are collected in the finished product tray. This process is repeated continuously for slicing.

[0037] like Figures 6-7 As shown, the pressure roller mechanism 3 also includes a distance adjustment assembly.
