Description

Technical Field

[0001] The invention relates to the technical field of file punching equipment, in particular to an automatic alignment punching machine for file binding. Background Art

[0002] In the work of archive management, in order to facilitate the preservation and consultation of archives, scattered archive papers need to be bound into volumes. Punching is an important part of the archive binding process. Therefore, the hole puncher used for archive binding and punching is an indispensable equipment in archive management work.

[0003] In the prior art, for example, Chinese patent publication number CN106272664A discloses a punching machine for file binding, which includes a base, a punching head connected to the base, a punching head with an operating rod, a punching operation port formed between the punching head and the base, and elastic connecting pieces fixedly connected to one side of the punching head symmetrically in front and back, a pressure roller connected to the two elastic connecting pieces for relative rotation, and the pressure roller is located outside the punching operation port. The elastic connecting piece is connected to the punching head on the upper side of the punching operation port, the elastic connecting piece is tilted, and the pressure roller contacts the base. A front and back transparent slide groove is provided on the base, the slide groove is provided along the left and right directions of the base, a slide plate is slidably connected to the slide groove, the front side and the rear side of the slide plate are respectively recessed inwards and slots are provided, a telescopic plate is movably inserted in the slot, and a baffle is fixedly connected to the outer end of the telescopic plate. Stoppers are fixedly connected to the front and back ends of the slide plate, respectively, and the stoppers are located outside the base, and the stoppers are in close contact with the base for relative sliding. The stoppers are located outside the telescopic plate.

[0004] Although the above-mentioned archive binding and punching machine can solve the sagging problem by setting a telescopic plate to hold up the paper and improve the binding effect, the existing archive punching machine is usually simple in structure. When in use, it is simply to place the stacked archive papers in the punching position and manually press the operating lever to generate pressure to squeeze the punching rod through the archive papers to form holes. In actual use, due to the lack of automatic alignment function, the stacked papers are often misaligned, which leads to deviations in the positions of the punched holes, resulting in the subsequent neat binding of the archives. In addition, during the binding process, when punching a large number of archive papers at one time, the punching rod contacts the topmost archive paper and continues to move downward. The pressure generated is likely to cause the lower archive paper to slide and shift, thereby causing the hole position to deviate, affecting the punching effect.

[0005] Therefore, an automatic alignment punching machine for file binding is proposed to solve the problems mentioned in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figure 1-Figure 10As shown, the present invention provides a technical solution: an automatic alignment punching machine for file binding, comprising: a shell component 1, a supporting component 2, a knocking component 3, a reinforcement component 4 and a punching component 5, the shell component 1 comprises a bottom shell 101, a triangular seat 102 is fixedly connected to the inner bottom of the bottom shell 101 near the front side, a fixed rack 103 is fixedly connected to the top of the triangular seat 102, guide grooves 105 are provided on the outer surfaces of both sides of the bottom shell 101 near the bottom, the supporting component 2 comprises a bottom plate 201, The rear surface of the bottom plate 201 is fixedly connected to the rear plate 203, and the outer surfaces of both sides of the bottom plate 201 near the edges are fixedly connected to guide shafts 202, and the guide shafts 202 are slidably inserted between the inner walls of the guide grooves 105. The knocking assembly 3 includes a wheel frame 301, and the wheel frame 301 is fixedly connected to a position near the front side of the bottom plate 201, and a rotating wheel 302 is rotatably connected between the inner walls of the wheel frame 301, and circular blocks 303 are rotatably connected to the outer surfaces of both sides of the wheel frame 301, and the rotating wheel 302 cooperates with the fixed rack 103.

[0026] The outer surfaces of both sides of the wheel frame 301 are fixedly connected to the positions near the rear side, the front side and the top of the mounting shell 305 are open, and the impact rack 306 is slidably connected between the inner surface walls, and the second spring 307 is fixedly connected between the bottom of the impact rack 306 and the inner bottom of the mounting shell 305. The two rotating wheels 302 are fixedly connected to the rotating wheels 302 through the shaft, and the outer surfaces of the rotating wheels 302 are symmetrically fixedly connected with tooth groups 304. The positions of the tooth groups 304 on the outer surfaces of the two rotating wheels 302 are staggered. The front surfaces of the group 304 and the impact rack 306 are meshed, and the mounting shell 305 is fixed on both sides of the wheel frame 301, and is used to install and accommodate the impact rack 306 and the second spring 307. The top of the impact rack 306 is provided with a rubber round head, which can reduce the impact damage to the bottom plate 201. The bottom of the impact rack 306 is provided with a hole, and the upper end of the second spring 307 is embedded in the impact rack 306, so that the impact rack 306 can move to the bottom of the mounting shell 305 when it moves downward, which can effectively shorten the length of the mounting shell 305. When the bottom plate 201 is pushed backward, the rotating wheel 302 and the fixed rack 103 are in meshing state. As the bottom plate 201 moves backward, the rotating wheel 302 will continue to rotate, and the rotating wheel 302 will drive the circular blocks 303 on both sides to rotate during the rotation process. Since the circular blocks 303 are symmetrically provided with tooth groups 304 on the surface, and each tooth group 304 occupies a quarter of the surface area of ​​the circular blocks 303, when the circular blocks 303 rotate, the two tooth groups 304 on the surface rotate to the rear side and collide with the inside of the mounting shell 305. When the rack 306 is engaged, as the circular block 303 rotates, the tooth group 304 will pull the impact rack 306 downward and squeeze the second spring 307 to contract. When the tooth group 304 passes over the impact rack 306, the impact rack 306 loses its limit. At this time, the second spring 307 will rebound and bounce the impact rack 306 and hit the bottom of the bottom plate 201. At the same time, since the tooth groups 304 on the surfaces of the two circular blocks 303 are staggered, the impact racks 306 on both sides will bounce up and hit the bottom of the bottom plate 201 in turn.

[0027] The position of the guide groove 105 near the front side is inclined upward, and the position of the front side of the guide groove 105 is parallel to the fixed rack 103. A first magnetic plate 104 is fixedly connected to the position near the top of the front side between the inner surface walls of the bottom shell 101. The first magnetic plate 104 and the bottom of the bottom plate 201 are magnetically connected. A second magnetic plate 108 is embedded in the inner surface wall of the rear side of the bottom shell 101 near the middle position below. The second magnetic plate 108 and the rear plate 203 are magnetically connected. The guide groove 105 plays a role in limiting the path of the guide shaft 202. Therefore, the push-pull bottom plate 20 1, the bottom plate 201 will move along the guide groove 105 as a whole. When the bottom plate 201 is in a front inclined position and a rear horizontal position, the bottom plate 201 and the guide groove 105 are both in a parallel state. When the bottom plate 201 is in the middle position of the guide groove 105, since the front and rear guide shafts 202 are respectively in the front and rear areas of the guide groove 105, the striking component 3 at the bottom of the bottom plate 201 will be in a suspended state, and the first magnetic plate 104 and the second magnetic plate 108 can be adsorbed and fixed to the bottom plate 201 and the rear plate 203 to improve the stability of the bottom plate 201.

[0028] An L-shaped plate 204 is symmetrically and slidably connected to the top of the bottom plate 201 near the edges on both sides, and a first bidirectional screw rod 212 is rotatably connected between the outer surfaces of the two sides of the bottom plate 201. The outer surfaces of the first bidirectional screw rod 212 are respectively threaded through the outer surfaces of the L-shaped plate 204. One end of the first bidirectional screw rod 212 is provided with a hexagonal head, and the positions of the hexagonal head and the guide groove 105 correspond. This design allows a hexagonal sleeve to be used to pass through the guide groove 105 and connect with the first bidirectional screw rod 212. By rotating the first bidirectional screw rod 212, the two L-shaped plates 204 that limit the paper size will approach or separate from each other under the action of the thread, and a scale corresponding to the L-shaped plate 204 is provided at the front edge of the bottom plate 201 to improve the adjustment accuracy.

[0029] The outer surfaces of both sides of the bottom shell 101 are symmetrically fixedly connected to the rear surface, and the outer surfaces of the two rotating shafts 107 are rotatably connected to the rotating plates 109. A pressure plate 110 is fixedly connected to the upper position between the outer surfaces of the two rotating plates 109. A gripping rod 111 is rotatably connected to the front side between the outer surfaces of the two rotating plates 109. A chip removal groove 112 is provided near the rear side of the bottom of the bottom shell 101, and an avoidance groove 112 is provided near the front side of the bottom of the bottom shell 101. 06. When in use, hold the handle 111 and press downward. At this time, the two rotating plates 109 will rotate forward with the rotating shaft 107 as the center and drive the pressure plate 110 to squeeze the punching component 5 downward. The chip groove 112 is in a through state from top to bottom. After the punching is completed, the paper scraps will fall downward through the chip groove 112. By providing a bottom bracket and a collection box for receiving the paper scraps for the device, the paper scraps generated by the punching can be easily collected. The avoidance groove 106 is mainly used to avoid the knocking component 3 that moves backward and gradually lowers.

[0030] The reinforcement component 4 includes a top plate 401, and the punching component 5 includes a connecting sleeve 501. The top plate 401 is fixedly connected between the inner surface walls of the bottom shell 101 near the rear side. A mounting bracket 406 is fixedly connected to the top of the top plate 401 near the rear edge. The mounting bracket 406 is L-shaped. A fixed punching rod 502 is connected to the bottom of the connecting sleeve 501 near the middle. The bottom of the connecting sleeve 501 is symmetrically slidably connected to the sliding punching rod 503 near the edges on both sides. A plurality of extension rods 505 are fixedly connected to the top of the connecting sleeve 501. The top of the extension rod 505 slides through the outer surface of the mounting bracket 406 and extends upward. The tops of the plurality of extension rods 505 are fixedly connected to each other. There is a connecting strip 506, and the outer sleeve of the extension rod 505 is provided with a third spring 507. The third spring 507 is arranged between the connecting sleeve 501 and the connecting strip 506. The top plate 401 and the bottom shell 101 are fixedly connected. The mounting frame 406 is installed at the top rear side of the top plate 401 for installing the punching assembly 5. The third spring 507 plays the role of pushing the connecting strip 506 upward. When the connecting strip 506 is pushed upward by the third spring 507, the connecting sleeve 501 will be driven to move upward through the extension rod 505. When the connecting sleeve 501 moves upward, it will drive the fixed punching rod 502 and the sliding punching rod 503 inserted with the archive paper to move upward, and the reset is completed at this time.

[0031] A pressure plate 206 is arranged above the L-shaped plate 204, and a plurality of connecting rods 207 are fixedly connected to the bottom of the pressure plate 206. The bottom end of the connecting rod 207 slides through the top of the L-shaped plate 204 and extends downward, and the bottom end of the connecting rod 207 is fixedly connected to the extrusion plate 208. A first spring 205 is sleeved on the outside of the connecting rod 207, and the first spring 205 is arranged between the L-shaped plate 204 and the pressure plate 206. The rear end of the pressure plate 206 is tilted downward, and avoidance openings 113 are symmetrically opened near the bottom of the rear surface of the bottom shell 101, and the positions of the avoidance openings 113 and the pressure plate 206 correspond to each other. The bottom of the top plate 401 is symmetrically slidably connected to sliding plates 402 near the edges on both sides, and the bottom of the sliding plate 402 is fixedly connected to a spring rod 403, and a pressure wheel 404 is installed at the bottom end of the spring rod 403. The surface of the pressure plate 206 is in conflict with the top of the pressure plate 206. During use, when the bottom plate 201 supporting the archival paper continues to move backward, the inclined rear side of the pressure plate 206 above the L-shaped plate 204 will be inserted under the pressure wheel 404 in the reinforcement component 4. As the bottom plate 201 continues to move, when the plane position of the pressure plate 206 is in contact with the pressure wheel 404, since the elastic force of the spring rod 403 connecting the pressure wheel 404 and the sliding plate 402 is greater than the elastic force of the first spring 205, the pressure plate 206 will be squeezed downward and the squeezing plate 208 is driven by the connecting rod 207 to squeeze and fix the paper. The archival paper that is squeezed and fixed is difficult to slide and shift relative to each other during the subsequent binding process. When the bottom plate 201 moves to the punching area on the rear side, the inclined rear end of the pressure plate 206 will pass through the avoidance opening 113.

[0032] A second bidirectional screw 407 is rotatably connected between the outer surfaces of both sides of the top plate 401. The outer surface of the second bidirectional screw 407 is threaded through the outer surfaces of the two sliding plates 402. The two sliding plates 402 are L-shaped. The outer surfaces of the opposite sides of the two sliding plates 402 are provided with sliding openings 405 near the rear side. The outer surfaces of the two sliding punching rods 503 on the opposite sides are both installed with sliding strips 504. The outer surfaces of the sliding strips 504 are slidably fitted with the inner surface walls of the sliding openings 405. The fixed punching rods 502 and the sliding punching rods 503 are both connected to the chip removal groove 1 12 positions correspond to each other, and the design makes it possible to use a hexagonal socket to pass through the reserved holes corresponding to the side of the bottom shell 101 and the position of the second bidirectional screw rod 407 and then connect with the second bidirectional screw rod 407. Then, after the second bidirectional screw rod 407 is rotated, the two sliding plates 402 at the bottom of the top plate 401 can be driven to move closer to or away from each other under the action of the thread, while the slide bar 504 and the sliding opening 405 are in an up and down sliding state. Therefore, when the sliding plate 402 moves horizontally, the slide bar 504 will follow the movement and drive the sliding punching rod 503 to move at the same time.

[0033] Slide grooves 211 are symmetrically provided at the top of the bottom plate 201 near the rear surface, and the bottoms of the two L-shaped plates 204 near the rear surfaces are fixedly connected with perforated blocks 209. The outer surface of the perforated block 209 is slidably connected to the inner wall of the slide groove 211. Avoidance holes 210 are provided on the outer surfaces of the perforated block 209 and the bottom plate 201. The three avoidance holes 210 correspond to the positions of the fixed punching rod 502 and the two sliding punching rods 503 respectively. When the positions of the two L-shaped plates 204 are adjusted by the first bidirectional screw rod 212, the L-shaped plates 204 will drive the perforated blocks 209 to move synchronously in the slide groove 211, thereby adjusting the positions of the avoidance holes 210 corresponding to the positions of the sliding punching rods 503.

[0034] The use method and working principle of the device: When the device is used to punch holes in archive paper during the archive management process, first move the supporting assembly 2 located at the rear side to the front side, and directly pull the bottom plate 201 during the movement. At this time, the guide shafts 202 inserted into the guide grooves 105 on both sides of the bottom plate 201 play a role in limiting the bottom plate 201, so that the bottom plate 201 is in a 30° inclined state after being pulled to the frontmost position, and when the bottom plate 201 is pulled to the frontmost position, the first magnetic suction plate 104 will absorb and fix the bottom plate 201 to stabilize the bottom plate 201. At this time, the bottom plate 201 and the rear plate 203 cooperate with the L-shaped plates 204 on both sides to form a shell for accommodating archive paper, and then place the archive paper to be punched on the bottom plate 201. At this time, the bottom of the paper will fit with the rear plate 203, and the two sides will fit with the L-shaped plates 204, completing the paper placement operation; Then the bottom plate 201 is pushed backwards. At this time, the rotating wheel 302 in the knocking assembly 3 below the bottom plate 201 and the fixed rack 103 on the top of the triangular seat 102 are in a meshing state. Therefore, as the bottom plate 201 moves backwards, the rotating wheel 302 will continue to rotate, and the rotating wheel 302 will simultaneously drive the circular blocks 303 on both sides to rotate during the rotation. Since the circular blocks 303 are symmetrically provided with tooth groups 304 on the surface, and each tooth group 304 occupies a quarter of the surface area of ​​the circular block 303, when the circular block 303 rotates, the two tooth groups 304 on the surface rotate to the rear position and mesh with the impact rack 306 inside the mounting shell 305. As the circular block 303 rotates, the tooth group 304 will pull the impact rack 306 downward and squeeze the second spring 307 to contract. When the impact rack 306 loses its limit, the second spring 307 will rebound and bounce the impact rack 306 and hit the bottom of the bottom plate 201. At the same time, since the tooth groups 304 on the surfaces of the two circular blocks 303 are staggered, the impact racks 306 on both sides will bounce up and hit the bottom of the bottom plate 201 in turn, so that the bottom plate 201 will be directly hit four times every time the rotating wheel 302 rotates one circle, and the bottom plate 201 in an inclined state and continuously hit will vibrate, which will destroy the friction between the stacked papers above, so that after relative movement, the bottom of all the papers will fit with the surface of the lowest rear plate 203, achieving the effect of simulating manual alignment of the papers, having the effect of automatically aligning the papers, solving the problem that the hole position of the misaligned stacked papers will be deviated when the holes are punched later, and improving the neatness of the files bound later; When the rear side of the bottom plate 201 supporting the archive paper slides to the horizontal position of the guide groove 105, the rotating wheel 302 will be in a suspended state and disengaged from the fixed rack 103. At this time, the archive paper will be in a stable state, and as the bottom plate 201 continues to move backward, the rear inclined part of the pressure plate 206 above the L-shaped plate 204 will be inserted under the pressure wheel 404 in the reinforcement component 4. When the plane position of the pressure plate 206 is in contact with the pressure wheel 404, since the elastic force of the spring rod 403 connecting the pressure wheel 404 and the sliding plate 402 is greater than the elastic force of the first spring 205, the pressure plate 206 will be squeezed downward and the squeezing plate 208 will be driven by the connecting rod 207 to squeeze and fix the paper. The squeezed and fixed archive paper is unlikely to slide and shift with each other during the subsequent binding process, thereby further ensuring the punching accuracy and improving the punching effect. When the rear plate 203 on the rear side of the bottom plate 201 is fixedly attached to the second magnetic plate 108 on the rear inner wall of the bottom shell 101, the bottom plate 201 can be stopped from being pushed, and then the gripping rod 111 is held and pressed downward. At this time, the two rotating plates 109 will rotate forward with the rotating shaft 107 as the center of the circle and drive the pressure plate 110 to press the connecting strip 506 in the punching assembly 5 downward. After the connecting strip 506 is pressed downward, it will squeeze the fixed punching rod 502 and the two sliding rods below through the extension rod 505 and the connecting sleeve 501. The punching rod 503 moves toward the file paper. When the bottom ends of the fixed punching rod 502 and the sliding punching rod 503 pass through the paper, the file punching operation is completed. The device is easy to operate. It only needs to place the file paper inside the supporting component 2 and then push the bottom plate 201 backward to automatically align the paper and press the paper, which greatly improves the file binding punching effect and punching efficiency. After the punching is completed, the bottom plate 201 is pulled to the front side and fixed to the first magnetic suction plate 104, and then the paper can be pulled out; Furthermore, when the device needs to be borrowed and holes need to be punched on papers of other sizes, a hexagonal sleeve can be used to pass through the guide groove 105 and then connected to the first bidirectional screw rod 212. By rotating the first bidirectional screw rod 212, the two L-shaped plates 204 that limit the paper size will approach or separate from each other under the action of the thread, and the scale on the front side of the bottom plate 201 can be observed during the adjustment of the L-shaped plate 204. During the adjustment process, the L-shaped plate 204 will drive the perforated block 209 to move synchronously in the slide groove 211, thereby adjusting the position of the avoidance hole 210 corresponding to the position of the sliding punching rod 503. Subsequently, the hexagonal sleeve can be used to pass through the side of the bottom shell 101 and the reserved hole corresponding to the position of the second bidirectional screw rod 407 and then connected to the second bidirectional screw rod 407. Then, the second bidirectional screw rod 407 is rotated. Under the action of the thread, the screw rod 407 can drive the two sliding plates 402 at the bottom of the top plate 401 to move closer to or away from each other. When the sliding plate 402 moves, it will not only drive the pressure wheel 404 to move through the spring rod 403, but also through the cooperation of the sliding opening 405 and the sliding bar 504, the sliding punching rod 503 will move synchronously with the sliding plate 402. During the adjustment process, the adjustment distance of the sliding punching rod 503 can be observed through the reserved opening on the rear side of the bottom shell 101 and the scale above the reserved opening. After the adjustment is completed, the pressure wheel 404 and the pressure plate 206 will be in the same straight line, and the sliding punching rod 503 and the avoidance hole 210 on the perforated block 209 will correspond to each other. No additional redundant operation is required to perform punching operations on papers of other sizes, thereby improving the practicality of the device.
