[0025] Embodiment 1

[0026] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown in the figure, the device includes an operation table 1 and a bracket 2. The bracket 2 is fixedly arranged on the top of the operation table 1. A cutting component 3 is arranged inside the bracket 2. The cutting component 3 includes a first motor 301 fixedly arranged at the upper right end inside the bracket 2. A crankshaft 302 is fixedly arranged on the left side of the first motor 301. A slide plate 303 is slidably connected to the middle end inside the bracket 2. A pull rod 304 is rotatably connected to the top of the slide plate 303. And one end of the pull rod 304 away from the slide plate 303 is rotatably sleeved on the middle end of the crankshaft 302. A second motor 305 is fixedly arranged on the left side of the top of the slide plate 303. An external part of the head end of the second motor 305 is fixedly sleeved with a cam 306. Guide holes 307 are integrally arranged on the left and right sides inside the slide plate 303. Mounting plates 308 are slidably connected to the left and right sides inside the guide holes 307. Blades 309 are fixedly arranged at the bottoms of the mounting plates 308. First springs 310 are fixedly arranged at the front and rear ends on the outer sides of the right mounting plates 308. And the right sides of the first springs 310 are fixedly connected to the mounting plates 308. Connecting rods 311 are fixedly arranged at the front and rear ends between the mounting plates 308 in pairs.

[0027] One end of the crankshaft 302 away from the first motor 301 is rotatably connected to the bracket 2. The first motor 301 is a stepping motor. And the first motor 301 stops running every time it rotates one week. A controller 4 is fixedly arranged on the outer wall of the bracket 2. The controller 4 is connected to the first motor 301 and the second motor 305 through wires. The second motor 305 is a high-speed motor. The staff first places the damping sheet on the operation table 1 and makes the area of the damping sheet to be cut coincide with the blades 309. Then the first motor 301 and the second motor 305 are started simultaneously. The first motor 301 drives the crankshaft 302 to drive the pull rod 304 to control the slide plate 303 together with the mounting plates 308 and the blades 309 to move along the direction of the damping sheet, so that the blades 309 perform a downward extrusion cutting process on the damping sheet. At the same time, the second motor 305 drives the cam 306 to rotate. The rotating cam 306 repeatedly squeezes the left mounting plate 308, so that the left mounting plate 308 drives the connecting rod 311 together with the blades 309 and the right mounting plate 308 to move along the direction of the guide holes 307, that is, the right mounting plate 308 repeatedly squeezes the first spring 310 to deform. By the above method, the blades 309 move reciprocally left and right along the direction of the guide holes 307, thereby increasing the cutting force of the blades 309 on the damping sheet, that is, improving the cutting effect of the blades 309 on the damping sheet.

[0028] Embodiment 2

[0029] As Figure 1 、 Figure 4As shown in the figure, a relief hole 5 is integrally provided at the inner top of the operating table 1. The relief hole 5 is designed as a through hole. The relief hole 5 corresponds to the blade 309 one by one. The width of the top view cross-section of the relief hole 5 is greater than the thickness of the top view cross-section of the blade 309. The length of the top view cross-section of the relief hole 5 is greater than the length of the top view cross-section of the blade 309. Connecting plates 6 are fixedly provided at the front and rear ends of the bottom of the sliding plate 303. A guiding groove 7 is integrally provided inside the connecting plate 6. A pressing plate 8 is slidably connected inside the guiding groove 7. A plurality of second springs 9 are fixedly provided on the top of the pressing plate 8 from left to right. The end of the second spring 9 away from the pressing plate 8 is fixedly connected to the connecting plate. The distance between the connecting plate 6 and the blade 309 is one centimeter. The distance between the bottom surface of the pressing plate 8 and the top surface of the operating table 1 is greater than the distance between the bottom surface of the blade 309 and the top surface of the operating table 1.

[0030] According to the operation method in Embodiment 1, when the sliding plate 303 drives the blade 309 to move along the direction of the damping sheet, the sliding plate 303 simultaneously drives the connecting plate 6 and the pressing plate 8 to move along the direction of the damping sheet. As a result, the pressing plate 8 squeezes the front and rear ends of the damping sheet to be cut, thereby fixing the position of the damping sheet. Through the reaction force of the damping sheet, the pressing plate 8 moves upward along the direction of the guiding groove 7, ensuring the stability of the blade 309 passing through the damping sheet and moving into the relief hole 5. At this time, the second spring 9 is deformed. Through the resilience of the second spring 9, the pressing plate 8 applies a soft squeezing force to the damping sheet, preventing the pressing plate 8 from applying too much squeezing force and damaging the damping sheet, and providing a protective treatment for the damping sheet.
