Description

Technical Field

[0001] This utility model relates to the field of paper fixing clamp technology, specifically a paper fixing clamp device for a punching machine with anti-slip function. Background Technology

[0002] In the paper processing industry, hole punchers are important pieces of machinery and are widely used in document binding, invoice processing, and other scenarios. The hole puncher's fixing fixture is a core component of the hole puncher. Its main function is to reliably position and fix the paper to ensure that the paper does not shift during the punching process, thereby ensuring the accuracy and consistency of the punching.

[0003] However, existing paper clamping devices for punching machines have a significant problem in practical use: insufficient anti-slip performance. When punching smooth paper or thick stacks of paper, traditional clamps often fail to provide enough friction, causing the paper to easily slip and shift during the punching process. This not only affects the accuracy and quality of punching but may also lead to paper waste due to punching position deviations, reducing production efficiency and increasing production costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a paper fixing clamp device for a punching machine with anti-slip function, which has the advantages of facilitating paper positioning and punching, preventing paper from slipping during the punching process, and solving the above-mentioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paper fixing clamp device for a punching machine with anti-slip function, comprising a paper placement plate, a positioning plate inserted into the side of the paper placement plate, a square hole through the upper surface of the positioning plate, a rectangular through hole through the top surface of the paper placement plate, a support plate fixedly connected to the lower surface of the paper placement plate, a collar fixedly connected to the center of the upper surface of the support plate, a spring I sleeved inside the collar, a sleeve sleeved on the outer surface of the spring I, a buckle plate fixedly connected to the top of the sleeve, a bending plate fixedly connected to the side of the buckle plate, a locking block fixedly connected to the upper surface of the bending plate, an L-shaped plate fixedly connected to one end of the positioning plate, a sleeve rod inserted into the top of the L-shaped plate, a spring II sleeved on the outer surface of the sleeve rod, a ball head fixedly connected to the top of the sleeve rod, and a pressure plate threadedly connected to the bottom end of the sleeve rod.

[0008] Preferably, the positioning plate has a rounded corner at one end relative to the L-shaped plate, and the paper placement plate has slots on both sides that fit the positioning plate.

[0009] Preferably, the upper surface of the positioning plate has a plurality of square holes arranged at equal intervals, and the top surface of the paper placement plate has a circular hole through which a buckle plate is inserted.

[0010] Preferably, the locking block fits into the square hole, the top end of the first spring abuts against the buckle plate, and the bottom end of the first spring abuts against the bracket plate.

[0011] Preferably, the top end of the second spring abuts against the bottom of the ball head, and the bottom end of the second spring abuts against the pressure plate, and the outer surface of the pressure plate is covered with an anti-slip silicone sleeve.

[0012] Preferably, the top surface of the paper placement plate is provided with a through groove, a limit block is slidably connected inside the groove, a screw is inserted inside the limit block, a knob is threaded on the outer surface of the screw, a perforated pad is fixedly connected to the upper surface of the paper placement plate, and a mounting bracket is fixedly connected to the side of the paper placement plate.

[0013] Compared with the prior art, this utility model provides a paper fixing clamp device for a punching machine with anti-slip function, which has the following beneficial effects:

[0014] 1. This utility model achieves precise positioning of paper of different sizes through an adjustable positioning plate, L-shaped plate and limiting block structure; after pressing the buckle to disengage the locking block from the square hole, the positioning plate can be flexibly pulled out to adjust the position, and the limiting block can be moved by loosening the knob, so that the side of the paper abuts against the L-shaped plate and the limiting block respectively. Combined with the punching pad to determine the punching position, the punching accuracy is ensured and paper waste is avoided due to positioning deviation.

[0015] 2. This utility model uses a pressure plate and an anti-slip silicone sleeve in conjunction with a positioning plate to clamp the paper, thereby improving the anti-slip performance. Pulling the ball head causes the pressure plate to move upward and compress the second spring. After placing the paper, releasing the ball head causes the second spring to return to its original position, causing the pressure plate to press down. The anti-slip silicone sleeve on its outer surface increases the friction force, which, together with the positioning plate, firmly fixes the paper on the paper placement plate, effectively preventing the paper from sliding or shifting during punching, ensuring punching quality, and reducing the problems of reduced production efficiency and increased costs caused by slippage.

[0021] 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.

[0022] Please see Figures 1-4 A paper fixing clamp device for a punching machine with anti-slip function includes a paper placement plate 1, a positioning plate 2 inserted into the side of the paper placement plate 1, a square hole 3 through the upper surface of the positioning plate 2, a rectangular through hole 4 through the top surface of the paper placement plate 1, a support plate 5 fixedly connected to the lower surface of the paper placement plate 1, a collar 6 fixedly connected to the center of the upper surface of the support plate 5, a spring 7 sleeved inside the collar 6, a sleeve 8 sleeved on the outer surface of the spring 7, a buckle plate 9 fixedly connected to the top of the sleeve 8, a bending plate 10 fixedly connected to the side of the buckle plate 9, a locking block 11 fixedly connected to the upper surface of the bending plate 10, an L-shaped plate 12 fixedly connected to one end of the positioning plate 2, a sleeve rod 13 inserted into the top of the L-shaped plate 12, a spring 14 sleeved on the outer surface of the sleeve rod 13, a ball head 15 fixedly connected to the top of the sleeve rod 13, and a pressure plate 16 threadedly connected to the bottom end of the sleeve rod 13.

[0023] Specifically, the positioning plate 2 has a rounded corner at one end relative to the L-shaped plate 12, and the paper placement plate 1 has slots on both sides that fit the positioning plate 2.

[0024] Specifically, the upper surface of the positioning plate 2 has multiple square holes 3 arranged at equal intervals, and the top surface of the paper placement plate 1 has a round hole through which a buckle plate 9 is inserted.

[0025] Specifically, the locking block 11 fits into the square hole 3, the top of the spring 7 abuts against the buckle plate 9, and the bottom of the spring 7 abuts against the bracket plate 5.

[0026] The advantage is that before punching the paper, by placing the paper on the upper surface of the paper placement plate 1 with the side of the paper abutting against the inner side of the L-shaped plate 12, and pressing the top of the buckle plate 9 to move it downward, the buckle plate 9 will compress the spring 7. At this time, the buckle plate 9 will drive the bending plate 10 to move downward, and the bending plate 10 will drive the locking block 11 connected to its upper surface to move downward. At this time, the locking block 11 will be removed from one of the square holes 3, so the positioning plate 2 is no longer limited. By pulling the positioning plate 2, it can be moved in the slots on both sides of the paper placement plate 1. This allows the position of the positioning plate 2 to be adjusted, which is convenient for flexibly adjusting the position of the positioning plate 2 according to the paper size, and achieving precise positioning.

[0027] Specifically, the top of spring 14 abuts against the bottom of ball head 15, and the bottom of spring 14 abuts against pressure plate 16, the outer surface of pressure plate 16 is covered with anti-slip silicone sleeve.

[0028] The advantage is that by pulling the ball head 15, it causes the sleeve rod 13 to move upward, and the sleeve rod 13 causes the pressure plate 16 to move upward. At this time, the pressure plate 16 compresses the second spring 14. When the edge of the paper touches the inside of the L-shaped plate 12 and the ball head 15 is released, it will touch the pressure plate 16 under the action of the second spring 14, causing it to move downward. The pressure plate 16 then works with the positioning plate 2 to press the paper down, which can prevent the paper from slipping during the subsequent punching process.

[0029] Specifically, a groove 17 is provided through the top surface of the paper placement plate 1. A limit block 18 is slidably connected inside the groove 17. A screw 19 is inserted inside the limit block 18. A knob 20 is threadedly connected to the outer surface of the screw 19. A perforated pad 21 is fixedly connected to the upper surface of the paper placement plate 1, and a mounting bracket 22 is fixedly connected to the side of the paper placement plate 1.

[0030] The advantages are that the position of the limiting block 18 can be adjusted by loosening the knob 20, and the side of the limiting block 18 abuts against the other side of the paper placement plate 1. In this way, together with the L-shaped plate 12 and the positioning plate 2, the paper punching position can be accurately positioned. A limiting piece is fixedly connected to the bottom of the screw 19 and abuts against the lower surface of the paper placement plate 1. The limiting block 18 can be locked by tightening the knob 20. The punching pad 21 is provided for contacting the punching tool during the punching process, and the mounting bracket 22 can be used to connect the punching machine.

[0031] In use, first, place the paper on the upper surface of the paper placement plate 1, so that the side of the paper abuts against the inner side of the L-shaped plate 12; then, press the top of the buckle plate 9 to compress the spring 7, which drives the bending plate 10 and the locking block 11 to move downward, causing the locking block 11 to retract from the square hole 3, releasing the positioning plate 2 from its limit, and pulling the positioning plate 2 to move within the slot. Adjust its position according to the paper size. After adjustment, release the buckle plate 9, the spring 7 returns to its original position, and the locking block 11 engages with the corresponding square hole 3 to fix the positioning plate 2; then, pull the ball... The head 15 moves the sleeve rod 13 and pressure plate 16 upward, compressing the second spring 14. After the edge of the paper touches the inside of the L-shaped plate 12, the head 15 is released, the second spring 14 returns to its original position, and the pressure plate 16 moves downward, cooperating with the positioning plate 2 to press the paper. By loosening the knob 20, the position of the limit stop 18 in the slide groove 17 is adjusted so that its side touches the other side of the paper. This, together with the L-shaped plate 12 and the positioning plate 2, completes the precise positioning of the paper punching position. Tightening the knob 20 locks the limit stop 18 through the screw 19.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
