[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-6The slot cover paper shearing mechanism shown in the figure comprises an upper knife seat 18, a lower knife seat 2 and a shearing drive mechanism, an upper cutter 7 is provided at the bottom of the back of the upper knife seat 18, a lower cutter 4 is provided at the top of the lower knife seat 2, a mounting base plate 14 is fixedly connected to the bottom of the lower knife seat 2, a guide groove 21 is provided at the top of the mounting base plate 14, and a discharge port 20 connected to the guide groove 21 is provided at the bottom of the front of the mounting base plate 14. The mounting base plate 14 is used to support and position the lower knife seat 2 to ensure that the position of the lower knife seat 2 is stable. At the same time, the cut material can be discharged from the discharge port 20 along the guide groove 21, making the discharge more convenient. A fastening screw 23 is threadedly inserted between the lower knife seat 2 and the lower cutter 4 and between the upper cutter 7 and the upper knife seat 18. The lower knife seat 2 and the lower cutter 4 are connected and fixed by the fastening screw 23. At the same time, the upper knife seat 18 and the upper cutter 7 are connected and fixed by the fastening screw 23. A fastening screw 23 is also used to connect and fix them, so that the upper cutter 7 on the upper cutter seat 18 and the lower cutter 4 on the lower cutter seat 2 can be disassembled and replaced. In this way, different cutting materials can be produced by replacing the lower cutter 4 and the upper cutter 7 with different incision shapes. Compared with the prior art, the shearing mechanism of this embodiment can be more adaptable to various production needs and has higher adaptability. At the same time, only the upper cutter 7 and the lower cutter 4 with different incision shapes need to be replaced, thereby reducing the cost of changeover, transformation and production; the shearing drive mechanism is arranged on the outside of the upper cutter seat 18 and the lower cutter seat 2, and the shearing drive mechanism is used to drive the upper cutter 7 and the lower cutter 4 to engage with each other to shear the slot cover paper. The shearing drive mechanism can drive the upper cutter 7 and the lower cutter 4 to engage with each other to cut the slot cover paper located between the two.

[0026] It should be noted that a guide block 19 is movably provided at the bottom of the upper knife seat 18 and located at the front position of the upper cutter 7. A fastening screw 22 is movably inserted in the long through hole opened at the top of the guide block 19. The fastening screw 22 is threadedly inserted with the front face of the upper knife seat 18. The top of the lower knife seat 2 is fixedly connected to the limit adjustment block 15. The guide block 19 is located directly above the limit adjustment block 15. The guide block 19 is installed on the upper knife seat 18 by a fastening screw 22. The long through hole on the guide block 19 for the fastening screw 22 to pass through is used to enable the guide block 19 to be installed on the upper knife seat 18. After being moved horizontally to the left and right, the lateral position of the guide block 19 can be adjusted; a guide adjustment seat 17 is fixedly connected to the front face of the upper knife seat 18, and a groove concave upward is provided in the middle of the bottom end of the guide adjustment seat 17. The top of the guide block 19 is located in the groove of the guide adjustment seat 17. Adjustment screws 24 are threadedly connected to the bottom of both sides of the adjustment seat 17, and the opposite ends of the two adjustment screws 24 extend into the groove of the guide adjustment seat 17 and fit with the side wall of the guide block 19. By manually screwing the adjustment screws 24 on the left and right sides of the guide adjustment seat 17, the guide block 19 can be pushed to move laterally through the adjustment screws 24. At the same time, the two adjustment screws 24 clamp each other to limit the position of the adjusted guide block 19, so that the guide block 19 is aligned with the limit adjustment block 15, which can eliminate the defect problem of inconsistent cutting caused by the reverse displacement of the material due to the processing error of the workpiece and the vibration generated by the operation of the machine in the prior art. By adjusting the lateral position of the guide block 19, it can be ensured that the boring machine is always on the symmetrical center line during operation, thereby achieving consistency in cutting and achieving the purpose of reducing the error generated during production cutting.

[0027] In addition, the shearing drive mechanism includes a guide sleeve 1 arranged on both sides of the lower knife seat 2, a connecting rod 3 is movably inserted inside the guide sleeve 1, a steel ball bushing 8 is fixedly sleeved on the outer wall of the connecting rod 3, a spring 9 is fixedly connected between the steel ball bushing 8 and the guide sleeve 1, and a connecting plate 12 is fixedly connected to the bottom ends of the two connecting rods 3. A cylinder 13 is provided above the connecting plate 12, and a floating joint 11 is fixedly connected to the bottom end of the connecting plate 12. A cylinder joint 10 is fixedly provided on the inner side of the floating joint 11, and the telescopic end of the cylinder 13 is connected to the cylinder joint 10. The connecting rod 3 can be driven to move by the action of the cylinder 13 in conjunction with the cylinder joint 10 and the floating joint 11. Since the position of the guide sleeve 1 is fixed, a relative position is generated between the guide sleeve 1 and the steel ball bushing 8 to squeeze the spring 9, so that the spring 9 is deformed to generate a reverse thrust, thereby facilitating the subsequent resetting of the connecting rod 3, so that the lower cutter 4 and the upper cutter 7 can be driven by the cylinder 13 to cut the slot cover paper.

[0028] The top ends of the two connecting rods 3 are fixedly connected with a mounting plate 5, and a cover plate 6 is provided on the front side of the mounting plate 5. The top of the upper knife seat 18 extends to the position between the mounting plate 5 and the cover plate 6. Plug screws 16 are inserted at both ends of the front side of the cover plate 6. The outer wall of the plug screw 16 passes through the back side of the upper knife seat 18 and is threadedly connected to the mounting plate 5. The mounting plate 5 cooperates with the cover plate 6 and the plug screw 16 to realize the connection and fixation of the upper knife seat 18 on the mounting plate 5. At the same time, for disassembly, you only need to remove the plug screw 16 and the cover plate 6 to disassemble the upper knife seat 18. The disassembly and assembly process is efficient and convenient, and better meets the use requirements.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
