Detailed Implementation

[0027] 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.

[0028] Example: Figure 1-7 As shown, this utility model provides an auxiliary device for cutting release paper, including a base 36. A feeding roller 1 is provided at one end of the base 36, and release paper is placed in the middle of the feeding roller 1. A first support frame 2 is fixedly connected to the base 36 adjacent to the feeding roller 1. Vacuum cleaners 3 are respectively provided at the upper and lower ends of the first support frame 2, and a vacuum hood 4 is connected to the input end of the vacuum cleaner 3. Slide rods 5 are respectively fixedly connected to the upper and lower ends of the first support frame 2 and the vacuum cleaner 3. The slide rods 5 are slidably connected to the vacuum cleaner 3. A lead screw 6 is rotatably connected to a vacuum cleaner 3. The lead screw 6 is threadedly connected to the vacuum cleaner 3. A drying box 7 is fixedly connected to the base 36 adjacent to the first support frame 2. A synchronous pulley 8 is fixedly connected to one end of the lead screw 6. The two synchronous pulleys 8 are driven by a synchronous belt 9. A first motor 10 is fixedly connected to one end of the top of the first support frame 2. The output end of the first motor 10 is fixedly connected to the lead screw 6. A hot air blower 11 is fixedly connected to the upper and lower ends of the drying box 7. Through holes 12 are provided on the side walls of both ends of the drying box 7. Release paper passes through the through holes 12 into the drying box 7.

[0029] In this embodiment, when cutting the release paper, the free end of the release paper wound on the unloading roller 1 is first pulled to pass between the two dust hoods 4 and through the two through holes 12 into the drying chamber 7. Then, the two vacuum cleaners 3 are turned on. Under the action of the vacuum cleaners 3, the dust on the top and bottom surfaces of the release paper is sucked into the vacuum cleaners 3 through the dust hoods 4. During this process, the first motor 10 is turned on. Driven by the first motor 10, the lead screw 6 located at the top of the first support frame 2 rotates. At this time, the lead screw 6 located at the bottom of the support frame rotates. The lead screw 6 of the part rotates synchronously under the transmission of the synchronous pulley 8 and the synchronous belt 9, so that the two vacuum cleaners 3 will start to move, thereby expanding the dust collection range of the vacuum cleaners 3, allowing the vacuum cleaners 3 to absorb the dust in the middle and both edges of the release paper. After passing through the dust removal part and the first support frame 2, the release paper will enter the drying box 7. At this time, the two hot air blowers 11 are turned on, and the damp release paper can be dried under the action of the hot air blowers 11. By removing dust and drying the release paper, the accuracy and stability of subsequent cutting can be improved.

[0030] Two electrostatic dust removal rollers 13 are rotatably connected to the side wall of the drying oven 7 away from the first support frame 2. The two electrostatic dust removal rollers 13 are located at the upper and lower ends of the through hole 12, respectively.

[0031] In this embodiment, the electrostatic dust removal roller 13 can further remove dust from the release paper, thereby improving the dust removal effect.

[0032] A second support frame 14 is fixedly connected to one end of the base 36 adjacent to the drying chamber 7. A first transition shaft 15 is rotatably connected to the top of one end of the drying chamber 7. A second transition shaft 16 is rotatably connected to the top of the second support frame 14 away from the first transition shaft 15. A third transition shaft 17 is rotatably connected between the second support frame 14 and the first transition shaft 15 and the second transition shaft 16. The third transition shaft 17 is located below the first transition shaft 15 and the second transition shaft 16.

[0033] In this embodiment, after the free end of the release paper passes through the drying box 7, it needs to be bypassed from the top of the first transition shaft 15, then from the bottom of the third transition shaft 17, and then from the top of the second transition shaft 16, thereby increasing the tension of the release paper and thus improving the stability during subsequent cutting.

[0034] The top of the second support frame 14 is fixedly connected to a support arm 18 between the first transition shaft 15 and the second transition shaft 16. One end of the support arm 18 is fixedly connected to a first cylinder 19. The output end of the first cylinder 19 is fixedly connected to a first U-shaped frame 20. One end of the first U-shaped frame 20 is rotatably connected to a pressing roller 21. The pressing roller 21 is located directly above the second transition shaft 16. One end of the side wall of the first U-shaped frame 20 is fixedly connected to a second motor 22. The output end of the second motor 22 is fixedly connected to the pressing roller 21.

[0035] In this embodiment, when the release paper passes over the top of the second transition shaft 16, the first cylinder 19 is opened, allowing the first cylinder 19 to drive the extrusion roller 21 to move downwards, so that the extrusion roller 21 and the second transition shaft 16 clamp the release paper. At this time, the second motor 22 is turned on to drive the extrusion roller 21 to rotate, so that the release paper can be conveyed for subsequent cutting.

[0036] The base 36 is located adjacent to the second support frame 14 and is fixedly connected to a cutting table 23. A lower blade 24 is fixedly connected to one end of the cutting table 23, and the top of the lower blade 24 is flush with the top of the cutting table 23. A second U-shaped frame 25 is fixedly connected to one end of the top of the cutting table 23. A second cylinder 26 is fixedly connected to one end of the top of the second U-shaped frame 25. A fixing plate 27 is fixedly connected to the output end of the second cylinder 26. Three springs 28 are fixedly connected to one end of the bottom of the fixing plate 27, and the fixing plate 27 is located inside the three springs 28. A damper 29 is fixedly connected to the plate 30, and a pressure plate 30 is fixedly connected to the spring 28 and the damper 29. An upper blade 31 is fixedly connected to the plate 27 located directly above the lower blade 24. A support frame 32 is fixedly connected to the base 36 located adjacent to the cutting table 23. A third cylinder 33 is fixedly connected to the upper and lower ends of the support frame 32. A third U-shaped frame 34 is fixedly connected to the output end of the third cylinder 33. A conveyor belt 35 is installed at one end of the third U-shaped frame 34. The two conveyor belts 35 are located at the upper and lower ends of the release paper, respectively.

[0037] In this embodiment, when the release paper is conveyed to the cutting table 23 by the pressure roller 21 and the second transition shaft 16, the free end of the release paper will pass through the cutting table 23 and fall onto the conveyor belt 35 below the support frame 32. At this time, the two conveyor belts 35 are opened, and the third cylinder 33 is opened, so that the two conveyor belts 35 clamp the release paper and convey it. At this time, the free end of the release paper is clamped. Then, the second cylinder 26 is opened, so that the second cylinder 26 drives the fixed plate 27 to move downward. During this process, the pressure plate 30 will press the release paper firmly on the cutting table 23. At this time, the fixed plate 27 continues to be driven downward by the second cylinder 26. At this time, the upper cutter will come into contact with the release paper. Under the action of the upper cutter and the lower cutter, the release paper can be cut. The release paper is clamped on both sides at the cutting point, so there will be no shaking, thereby improving the cutting stability.

[0038] Working principle: When cutting the release paper, the free end of the release paper wound on the unloading roller 1 is first pulled, allowing it to pass between the two dust hoods 4 and through the two through holes 12 into the drying chamber 7. Then, the two vacuum cleaners 3 are turned on. Under the action of the vacuum cleaners 3, the dust on both sides of the release paper is sucked into the vacuum cleaners 3 through the dust hoods 4. During this process, the first motor 10 is turned on. Driven by the first motor 10, the lead screw 6 located at the top of the first support frame 2 rotates. At this time, the lead screw 6 located at the bottom of the support frame rotates synchronously under the transmission of the synchronous pulley 8 and the synchronous belt 9. When the lead screw 6 rotates, the vacuum cleaners 3 begin to move, allowing the vacuum cleaners 3 to pass through the release paper. The vacuum cleaner 3 moves from the middle to both edges to expand its suction range. During dust removal, the release paper remains stationary. Each time the vacuum cleaner 3 completes one cycle, the release paper is conveyed again, achieving comprehensive dust removal. After passing through the dust removal section and the first support frame 2, the release paper enters the drying chamber 7. At this point, two hot air blowers 11 are turned on, drying the damp release paper. After passing through the drying chamber 7, the release paper passes between two electrostatic dust removal rollers 13. These rollers further remove dust, improving the dust removal effect. By performing dust removal and drying on the release paper, the precision and stability of subsequent cutting can be improved.

[0039] After the free end of the release paper passes through the two electrostatic dust removal rollers 13, it needs to be routed around the top of the first transition shaft 15, then around the bottom of the third transition shaft 17, and then around the top of the second transition shaft 16. This increases the tension of the release paper and improves the stability during subsequent cutting. When the release paper passes over the top of the second transition shaft 16, the first cylinder 19 is opened, driving the pressure roller 21 downwards. The pressure roller 21 and the second transition shaft 16 clamp the release paper. At this time, the second motor 22 is turned on to drive the pressure roller 21 to rotate, thus conveying the release paper for subsequent cutting. When the release paper is conveyed to the cutting table 23 by the pressure roller 21 and the second transition shaft 16, the release paper... The free end of the release paper passes through the cutting table 23 and falls onto the conveyor belt 35 below the support frame 32. At this time, the two conveyor belts 35 are opened, and the third cylinder 33 is opened at the same time, so that the two conveyor belts 35 clamp the release paper and transport it. At this time, the free end of the release paper is clamped. Then, the second cylinder 26 is opened, so that the second cylinder 26 drives the fixed plate 27 to move downward. During this process, the pressure plate 30 will press the release paper firmly on the cutting table 23. At this time, the fixed plate 27 continues to be driven downward by the second cylinder 26. At this time, the upper cutter will come into contact with the release paper. Under the action of the upper cutter and the lower cutter, the release paper can be cut. The release paper is clamped on both sides at the cutting point, so there will be no shaking, thereby improving the cutting stability.

[0040] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
