[0021] Furthermore, a horizontal moving module for driving the moving plate 2 to move is provided at the top of the machine base 1. The output end of the horizontal moving module is fixedly connected to the bottom end of the moving plate 2. The start and stop of the horizontal moving module is controlled by the control panel 3, thereby controlling the moving distance of the moving plate 2, so that the moving plate 2 drives the polishing pad stacked on the top of the moving plate 2 to move synchronously, and the polishing pad is moved to the bottom end of the mounting frame 4 for cutting.

[0022] Specifically, an installation cavity for installing the cutting mechanism is opened inside the installation frame 4, the top of the cutting mold 8 is fixedly connected to a pressing plate 6 for pressing the cutting mold 8, the top of the pressing plate 6 is provided with a hydraulic cylinder 5 for driving the pressing plate 6, the bottom end of the hydraulic cylinder 5 is fixedly connected to a mounting plate 7 for installing the hydraulic cylinder 5, both ends of the mounting plate 7 are respectively fixedly connected to the inner wall of the mounting cavity, the output end of the mounting plate 7 is fixedly connected to the top of the pressing plate 6, both ends of the pressing plate 6 are respectively fixedly connected to guide blocks 14, and guide grooves for inserting the guide blocks 14 are respectively opened on both sides of the inner wall of the mounting cavity.

[0023] Furthermore, the hydraulic cylinder 5 is electrically connected to the control panel 3, and the start and stop of the hydraulic cylinder 5 can be controlled by the control panel 3. The hydraulic cylinder 5 is fixedly connected to the pressing plate 6 through a connecting flange. The hydraulic cylinder 5 is installed in the middle position of the pressing plate 6, and the end of the mounting plate 7 is fixedly connected to the inner wall of the mounting cavity by welding. The size of the guide groove is 1.01 times the size of the guide block 14, thereby ensuring that when the hydraulic cylinder 5 drives the pressing plate 6, the pressing plate 6 will not rotate and maintain vertical movement.

[0024] Specifically, a cutting groove for cutting the polishing pad is provided at the bottom end of the cutting die 8, the top end of the cutting die 8 is fixedly connected to the bottom end of the pressing plate 6, the pushing rod 9 is connected through the cutting groove, the top end of the pressing plate 6 is fixedly connected to a fixing plate 10, a round hole is provided at the top end of the fixing plate 10, the pushing rod 9 is connected through the round hole, the top end of the pushing rod 9 is fixedly connected to a baffle 12, the outer wall of the pushing rod 9 is provided with a pushing spring 11 for pushing the baffle 12, the top end of the baffle 12 is provided with a limit plate 13 for limiting the movement of the baffle 12, and the two ends of the limit plate 13 are fixedly connected to the inner wall of the mounting cavity.

[0025] Further, a plurality of cutting dies 8 are provided at the bottom end of the pressing plate 6. The plurality of cutting dies 8 are arranged at equal intervals on both sides of the bottom end of the pressing plate 6 with the hydraulic cylinder 5 as the symmetry axis. The shape of the cutting dies 8 is the same as the shape required for cutting. The size of the cutting groove is the same as the shape of the cutting dies 8. The size of the cutting groove is the size required for cutting the polishing pad. The thickness of the cutting dies 8 is 1.02 times the thickness of the cutting and superimposed polishing pad. The size of the circular hole is 1.02 times the size of the pushing rod 9.

The top of the fixed plate 10 is fixedly connected, and the limit plate 13 is not fixedly connected to the baffle plate 12, but only in close contact. When the hydraulic cylinder 5 drives the pressing plate 6 to retract, the limit plate 13 will push the baffle plate 12, driving the baffle plate 12 to insert into the position of half the thickness of the cutting groove or the bottom of the cutting groove, so as to ensure that the polishing pad completely falls off from the cutting groove after cutting, and realize automatic unloading. When cutting is required, the hydraulic cylinder 5 drives multiple cutting dies 8 to squeeze and cut the polishing pad by pushing the pressing plate 6, and the polishing pad squeezes the pushing rod 9, so that the pushing rod 9 The baffle plate 12 is driven to move away from the cutting die 8, and the baffle plate 12 drives the pushing spring 11 to stretch the pushing spring 11. When the hydraulic cylinder 5 drives the pressing plate 6 to retract, the restoring force of the pushing spring 11 drives the baffle plate 12 to move close to the cutting die 8, and the baffle plate 12 drives the pushing rod 9 to move synchronously, thereby squeezing the polishing pad nested in the cutting groove and pushing it in the direction of leaving the cutting groove to realize automatic unloading. When the polishing pad is firmly nested and cannot be unloaded under the action of the pushing spring 11, the baffle plate 12 is moved away from the cutting die 8. The plate 12 moves to the bottom end of the limit plate 13, and the limit plate 13 limits the movement of the baffle 12. The pressing plate 6 continues to be recovered along with the output end of the hydraulic cylinder 5, so that the pushing rod 9 squeezes the polishing pad, thereby ensuring that the polishing pad completely falls out of the cutting groove. No manual unloading is required, thereby saving manpower. At the installation position of the hydraulic cylinder 5, if the hydraulic cylinder 5 and the pushing rod 9 cannot be installed, the part of the polishing pad that has not been cut will be moved to the place where the cutting mold 8 is installed for cutting after cutting in other parts, so as to ensure the utilization rate of the polishing pad raw material.
