A spring three 22 is arranged inside the spacer 17, and one end of the spring three 22 is fixedly connected to one side of the inner wall of the spacer 17, and the other end of the spring three 22 is fixedly connected to one side of the block 21. The rear end of the bracket 2 is rotatably connected with a cleaning component, and the cleaning component here is used to clean up the fine debris on the surface of the circular knife 13 to ensure the quality of the product.

[0039] Reference Figures 5-7 The cleaning assembly includes two rotating shafts 3 23, the outer side walls of the two rotating shafts 3 23 are rotatably connected to the inner walls of the left and right sides of the bracket 2, and the adjacent sides of the two rotating shafts 3 23 are fixedly connected with a brush box 24, and the inner wall of the brush box 24 is slidably connected with a brush 25. The brush 25 here is used to clean the circular knife 13, and the other side of the brush 25 is fixedly connected with a limiting plate 26, and the limiting plate 26 here is used to prevent the brush 25 from escaping from the sliding space of the brush box 24. The outer side of the limiting plate 26 is slidably connected to the inner wall of the brush box 24, and the other side of the limiting plate 26 is fixedly connected with a plurality of inner plates 27, and the other side of the inner plate 27 is slidably connected with two sliders 28, and the inner wall of the slider 28 is rotatably connected with a support rod 29, and the brush 25 here transmits force to the inner plate 27 when being squeezed by the knife roller 12 and the circular knife 13, so that the two support rods 29 rotate and drive the slider 28 to slide to both sides;

[0040] The outer wall of the support rod 29 is rotatably connected to the inner column 30, and the outer side of the inner column 30 is slidably connected to the outer column 31. A spring four 32 is arranged inside the outer column 31, and one end of the spring four 32 is fixedly connected to one side of the inner column 30. At the same time, the support rod 29 here will squeeze the inner column 30, thereby further squeezing the spring four 32 to shrink it, provide a reaction force, and then feed this force upward, so that the brush 25 can be squeezed tighter with the knife roller 12 and the circular knife 13, thereby improving the cleaning effect. The other end of the spring four 32 is fixedly connected to one side of the inner wall of the outer column 31, and one end of the two support rods 29 is rotatably connected to a turntable 33, and the other side of the turntable 33 is rotatably connected to an outer plate 34, and one side of the outer plate 34 is fixedly connected to the inner wall of the brush box 24. The brush box 24 here provides stable support for the outer plate 34.

[0041] Working principle: First, the material to be punched is bypassed from the top of the pulling roller 16, then passes through the airspace above the cutter roller 12, and then passes through the airspace above the grinding roller 8. The bracket 2 here mainly provides a stable support for the pulling roller 16, the cutter roller 12, and the grinding roller 8. At this time, the motor 4 on the inner wall of the bottom block 3 can be started. At this time, the motor 4 will drive the main shaft 5 to rotate, thereby driving the rotation of the first gear 6, the first rotating shaft 7, and the grinding roller 8. Also, because the first gear 6 and the second gear 9 here are meshed, the second gear 9, the second rotating shaft 10, the hollow shaft 11, and the cutter roller 12 will be driven to rotate simultaneously. During rotation, the circular cutter 13 on the surface of the cutter roller 12 will punch the material into the shape required by the customer, and then the ejector rod 14 and the first spring 15 cooperate to eject the waste material and output the punched material.

[0042] At this time, if it is necessary to replace the template, the button 18 can be pressed first. At this time, the button 18 will slide into the inside of the clamping block 21, so that it is disengaged from the clamping with the bracket 2. The limiting disc 20 here mainly plays a limiting role, while the second spring 19 and the third spring 22 play a resetting role. Then the spacer block 17 is taken out. At this time, the cutter roller 12 is slightly rotated so that the notch of the second rotating shaft 10 faces oneself, and then the cutter roller 12 can be taken out to replace the template. After completion, the cutter roller 12 and the spacer block 17 are put back and re-clamped.

[0043] When this equipment is operating, the brush 25 inside the brush box 24 here will sweep the fine debris formed on the surface of the circular cutter 13 during punching to prevent it from affecting the product quality. And when the brush 25 presses against the circular cutter 13 here, the acting force will be transmitted to the limiting plate 26 and further to the inner plate 27. At this time, the support rod 29 will rotate towards both sides around the turntable 33 under the pressure, and at the same time drive the slider 28 to slide towards both sides. Also, the support rod 29 here will press against the inner column 30, so that it presses the spring four 32 inside the outer column 31, causing it to contract, and at the same time generating a reaction force, making the brush 25 press against the circular cutter 13 more tightly and improving the cleaning effect.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
