[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a pressure uniform distribution device for cutting tuning paper, comprising a fixed frame 1, a pressure mechanism 2 fixedly connected to the top of the inner wall of the fixed frame 1, the pressure mechanism 2 being used to uniformly distribute pressure, and an adjustment mechanism 3 slidably connected to the bottom of the outer wall of the pressure mechanism 2, the adjustment mechanism 3 being used to adjust the cutting angle. The pressure mechanism 2 includes a fixed plate 201, the fixed plate 201 being slidably connected to the top of the inner wall of the fixed frame 1, a counterweight plate 202 fixedly connected to the top of the outer wall of the fixed plate 201, and a plurality of sliding strips 203 fixedly connected to the middle of the inner wall of the counterweight plate 202. A counterweight 204 is slidably connected to the top of the outer wall of multiple sliders 203. Springs 205 are fixedly connected to the four corners of the top of the counterweight plate 202. A drive assembly 206 is fixedly connected to the top of the outer wall of multiple springs 205. The drive assembly 206 includes a hydraulic push rod 2061. The hydraulic push rod 2061 is fixedly connected to the top of the outer wall of the spring 205. An air inlet 2062 is opened on the right side of the top of the hydraulic push rod 2061. A push plate 2063 is fixedly connected to the output end of the hydraulic push rod 2061. A gasket 2064 is fixedly connected to the bottom of the outer wall of the push plate 2063.

[0032] Specifically, when the tuning paper needs to be cut, the hydraulic push rod 2061 takes in air through the air inlet 2062. The internal gas pushes the push plate 2063 downward, and the pad 2064 at the bottom of the push plate 2063 applies downward pressure accordingly. During this process, the spring 205 acts as a buffer and shock absorber to prevent damage to the tuning paper caused by excessive pressure. It can also assist the pressure mechanism 2 in resetting after cutting to achieve even pressure distribution. The weight of the counterweight plate 202 can be adjusted by moving the position of the counterweight block 204 on the slide bar 203. The counterweight 204 is placed in a suitable position according to the actual cutting requirements, so that different areas can bear the corresponding proportion of pressure when the pressure mechanism 2 is pressed down. This allows the fixed plate 201 to evenly transfer the pressure to the tuning paper. The adjustment mechanism 3, which is slidably connected to the bottom of the outer wall of the pressure mechanism 2, can flexibly adjust the cutting angle according to different cutting requirements. While the pressure mechanism 2 provides uniform pressure when it is pressed down, the adjustment mechanism 3 ensures that the cutting blade 304 cuts the tuning paper at a suitable angle, thereby meeting diverse production needs.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The adjustment mechanism 3 includes a movable frame 301, which is slidably connected to the middle of the inner wall of the fixed frame 1. A fixed frame 302 is rotatably connected to the middle of the inner wall of the movable frame 301. Rollers 303 are rotatably connected to the four corners at the bottom of the fixed frame 302. A cutting blade 304 is slidably connected to the middle of the inner wall of the fixed frame 302. Nuts 305 are threadedly connected to the left and right ends of the outer wall of the cutting blade 304. A rotating assembly 306 is fixedly connected to the right side of the outer wall of the movable frame 301. The rotating assembly 306 includes a motor 3061, which is fixedly connected to the right side of the inner wall of the movable frame 301. A turntable 3062 is fixedly connected to the output end of the motor 3061. An adjusting rod 3063 is rotatably connected to one side of the top of the turntable 3062. The other side of the adjusting rod 3063 is rotatably connected to the right side of the outer wall of the fixed frame 302. Connecting rods 3064 are rotatably connected to the four corners at the top of the fixed frame 302.

[0034] Specifically, the motor 3061 in the rotating assembly 306 starts, driving the turntable 3062 to rotate, which in turn changes the angle and position of the adjusting rod 3063, pushing the fixed frame 302 to rotate to adjust the cutting angle. The roller 303 at the bottom of the fixed frame 302 provides support during rotation to ensure a smooth process. The cutting blade 304 can slide on the inner wall of the fixed frame 302 to adjust its extension length and is fixed by a nut. The moving frame 301 can slide on the inner wall of the fixed frame 1, driving the adjusting mechanism 3 to move horizontally and align with different cutting positions. Under the uniform pressure provided by the pressure mechanism 2, the adjusting mechanism 3 makes the cutting blade 304 cut the tone paper at a suitable angle and position to meet production needs.

[0035] Reference Figure 1 , Figure 2 and Figure 3 An operating table 4 is fixedly connected to the front side of the outer wall of the fixed frame 1. Multiple buttons 5 are fixedly connected to the top of the outer wall of the operating table 4. A nut 7 is fixedly connected to the top of the outer wall of the spring 205. A washer 6 is fixedly connected to the middle of the inner wall of the nut 7. Buffer pads 8 are fixedly connected to the left and right sides of the bottom of the fixed frame 1. Multiple vent holes 9 are opened in the middle of the inner wall of the buffer pad 8. Limiting rods 10 pass through the four corners of the bottom of the fixed plate 201. Limiting plate 11 is fixedly connected to the bottom of the outer wall of the limiting rod 10.

[0036] Specifically, the operator can issue a command through the button 5 on the top of the control panel 4 to start the equipment. The fixed frame 1 contacts the external support surface through the buffer pad 8 at the bottom. The vent hole 9 on its inner wall can discharge air when under force, which enhances the buffering effect and ensures the stability of the equipment operation. The limiting rod 10 at the bottom of the fixed plate 201 passes through and cooperates with the limiting plate 11 to play a guiding and limiting role, preventing the fixed plate 201 from deviating from the displacement. The nut 2 7 and washer 6 connected to the top of the spring 205 can flexibly adjust the preload of the spring 205. The washer 6 can also prevent the nut 2 7 from loosening, thus providing stable elastic support and buffer for the relevant components during the operation of the equipment.

[0037] Working principle: The hydraulic push rod 2061 is started by air intake through the air inlet 2062. Its output end drives the push plate 2063 to move down. The pad 2064 at the bottom of the push plate 2063 contacts the lower component to transmit pressure. At the same time, the spring 205 plays a role in buffering and elastic support, which can initially adjust the pressure. The counterweight plate 202 on the fixed plate 201 and its slide bar 203 and counterweight block 204 constitute an adjustable counterweight system. By sliding the counterweight block 204, the counterweight distribution is changed. In conjunction with the hydraulic push rod 2061, the pressure is output to achieve uniform pressure distribution. The pressure mechanism 2 transmits the uniformly distributed pressure to the slidingly connected adjustment mechanism 3, providing stable and uniform pressure support for the cutting work after adjusting the cutting angle.

[0038] When the equipment needs to perform a cutting operation, the motor 3061 starts, driving the turntable 3062 to rotate. The adjusting rod 3063 on one side of the top of the turntable 3062 moves accordingly. Since the other side of the adjusting rod 3063 is rotatably connected to the right side of the outer wall of the fixed frame 302, the fixed frame 302 is pushed to swing back and forth within the moving frame 301, thereby adjusting the cutting angle. The roller 303 at the bottom of the fixed frame 302 can reduce the frictional resistance between it and the moving frame 301, ensuring smooth movement. At the same time, the operator can adjust the position of the cutting blade 304 through the nut 305 to adapt to different cutting needs. The connecting rod 3064 at the top of the fixed frame 302 plays an auxiliary support and stabilizing role during the movement, ensuring that the entire adjusting mechanism 3 operates smoothly and reliably.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
