Automatic alignment punching machine for file binding

Abstract

The present invention discloses an automatic alignment punch for file binding, which belongs to the technical field of punching machines. An automatic alignment punch for file binding comprises a punch body and a support platform fixedly installed on the inner bottom surface thereof, wherein a plurality of file bags to be punched are stacked on the surface of the support platform, and a front clamping plate and two side clamping plates are slidably connected to the surface of the support platform. Compared with traditional punching devices, the automatic alignment punch for file binding can complete the centering and positioning of the stacked file bags during the punching process, and at the moment of punching, since the lower hole ring and the upper hole ring are in contact with the top and bottom surfaces of the stacked file bags, when the punch punches the stacked file bags, the lower hole ring and the upper hole ring can effectively prevent the occurrence of dents or cracks around the cut holes, which not only improves the punching speed of the punch body on the file bags, but also improves the punching quality of the punch body on the file bags.

Description

Technical Field

[0001] The present invention relates to the technical field of hole punchers, and more particularly to an automatic alignment hole puncher for file binding. Background Art

[0002] A hole punch is a tool that uses physical means to make holes in materials such as paper, leather, and plastic. It is widely used in office, handicrafts, financial binding and other fields.

[0003] Chinese patent application number CN202510300674.1 discloses an automatic alignment punching machine for file binding, which relates to the technical field of file punching equipment, including: a shell assembly, a supporting assembly, a knocking assembly, a reinforcement assembly and a punching assembly. The shell assembly includes a bottom shell, and a triangular seat is fixedly connected to the inner bottom of the bottom shell near the front side, and a fixed rack is fixedly connected to the top of the triangular seat. Guide grooves are provided on the outer surfaces of both sides of the bottom shell near the bottom.

[0004] The above technical solution solves the problem that the hole position deviation will occur when the misaligned stacked papers are subsequently punched, thereby improving the neatness of the files bound subsequently. In addition, the squeezed and fixed file papers are less likely to slide and shift with each other during the subsequent binding process, thereby further ensuring the accuracy of the punching and improving the punching effect. When punching file bags with traditional punching machines, multiple file bags are manually stacked neatly, and then the stacked file bags are pre-fixed by external clamps or manual pressing, and then the punching device is started to complete the punching operation. However, the traditional punching machine needs to divide "fixing" and "punching" into two independent steps, resulting in a cumbersome process. Especially when processing large quantities of file bags, manual stacking, fixing and repeated loading and unloading operations are time-consuming, and the fixing link is prone to alignment deviation due to differences in human operation, affecting the punching accuracy and speed of the file bag by the punching machine. Moreover, during the punching process, the instantaneous extrusion pressure applied by the puncher will be concentrated around the hole, resulting in dense compression of local paper fibers in the file bag and formation of concave deformation around the hole. In severe cases, the punched holes of the file bag will crack, affecting the punching quality of the file bag. Traditional punching machines lack an effective debris collection system, and the paper scraps generated by punching are directly scattered on the surface of the file bag and the work surface, requiring manual secondary cleaning.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) When the automatic alignment punching machine for file binding is in use, the lifting plate moves downward, bringing the lifting frame and roller downward. The downward movement of the roller first squeezes the inclined rail, and at this time, the multiple inclined rails are squeezed and move with the front splint and the two side splints in the middle. The stacked file bags are clamped and fixed by the front splint, the two side splints and the fixed plate. The upper rail is squeezed and moves with the common fixed frame. The common fixed frame moves and brings multiple vertical frames to slide inside the slot. The vertical frame moves with the guide rod and the slide plate at the same time. The guide rod and the slide plate slide and the lower hole ring and the upper hole ring slide at the same time. The lower hole ring and the upper hole ring move. When the holes are moved to correspond to the positions of the holes, the lower hole ring and the upper hole ring have a slight clamping effect on the stacked file bags. Compared with the traditional punching device, this device can complete the center clamping and positioning of the stacked file bags during the punching process, and at the moment of punching, since the lower hole ring and the upper hole ring are in contact with the top and bottom surfaces of the stacked file bags, when the hole puncher punches holes in the stacked file bags, the lower hole ring and the upper hole ring can effectively prevent dents or cracks around the cut holes, which not only improves the punching speed of the punch body on the file bags, but also improves the punching quality of the punch body on the file bags.

[0019] 2) When using this automatic alignment punching machine for file binding, open the switch door according to the thickness of the file bag, hold the handle and push and pull. At this time, the movement of the interval tooth plate drives the adjustment gear to rotate, and the rotation of the adjustment gear drives the rotating shaft to rotate, which makes the screw rotate, and then the slide plate moves inside the vertical frame. At the same time, the slide plate slides up and down in the slide groove, realizing the adjustment of the spacing between the lower hole ring and the upper hole ring, so that the spacing between the lower hole ring and the upper hole ring is suitable for the thickness of the stacked file bags to be punched, and the punching machine body can punch file bags with different stacking thicknesses, increasing the practicality of the equipment.

[0020] 3) When the automatic alignment punch for file binding is in use, when the hole punch passes through the lower hole ring and the upper hole ring to punch holes in the file bag, there will be paper scraps inside the hole punch. As the hole punch continues to move downward to pass through the hole, the ball head contacts the surface of the file bag and is squeezed. The lifting gear plate moves upward to squeeze the fourth spring, and at the same time drives the rotating gear to rotate. The rotating gear drives the chip removal rod to move downward in the hole punch. The chip removal rod moves to push out the paper scraps inside the hole punch, and the pushed out paper scraps fall into the paper scrap box for collection, preventing the paper scraps from being scattered directly on the surface of the file bag and the work surface, thereby ensuring the cleanliness of the file bag surface and the work surface.

The punchers 18 are conventional punchers 18 in the prior art. The number of punchers 18 and the holes 37 are the same and their positions correspond. The lifting plate 16 moves downward, bringing the lifting frame 17 and the roller 19 downward. The roller 19 first squeezes the inclined rail 7 downward.

[0041] A common fixing frame 26 is fixedly installed on the surface of multiple vertical frames 24, a vertical rail 28 is fixedly installed on the surface of the common fixing frame 26, and an upper rail 27 connected to the vertical rail 28 is fixedly installed on the surface of the vertical rail. The slope of the upper rail 27 is greater than the slope of the inclined rail 7, and the height of the upper rail 27 is lower than the height of the inclined rail 7, thereby achieving the purpose of first clamping the file bag 3 and then punching the file bag 3.

The telescopic end of the telescope 38 is fixedly connected to the surface of the lifting plate 16. A switch door 39 corresponding to the position of the handle 34 is opened on the surface of the punch body 1.

[0045] The steps of using the present invention are as follows: when using the automatic alignment punching machine for file binding, first manually stack multiple file bags 3 together, and then place them on the surface of the support table 2. According to the thickness of the file bags 3, open the switch door 39, hold the handle 34 to push and pull, and at this time, the spacing tooth plate 31 moves and drives the adjustment gear 30 to rotate, and the rotation of the adjustment gear 30 drives the rotating shaft 29 to rotate, so that the screw rod 25 rotates, and then the slide plate 14 moves inside the vertical frame 24. At the same time, the slide plate 14 slides up and down in the slide groove 13, realizing the adjustment of the spacing between the lower hole ring 12 and the upper hole ring 15, so that the spacing between the lower hole ring 12 and the upper hole ring 15 is suitable for the thickness of the stacked file bags 3 to be punched, and the telescopic device 38 extends and drives the lifting plate 16 to descend, and the lifting plate 16 moves downward and drives the lifting frame 17 and roller 19 move downward, the downward movement of roller 19 first squeezes the inclined rail 7, at this time, multiple inclined rails 7 are squeezed and respectively carry the front splint 4 and the two side splints 5 to move in the center, the front splint 4 and the two side splints 5 move in the center to move multiple stacked file bags 3 in the center, when the roller 19 moves to the junction of the inclined rail 7 and the vertical flat rail 8, the stacked file bags 3 are clamped and fixed by the front splint 4, the two side splints 5 and the fixed plate 6, when the roller 19 moves to the junction of the inclined rail 7 and the vertical flat rail 8, one of the rollers 19 contacts the surface of the upper rail 27, as the lifting plate 16 continues to descend, at this time one of the rollers 19 squeezes the upper rail 27, and the other rollers 19 move to the surface of the vertical flat rail 8, and the upper rail 27 is squeezed and moves with The common fixing frame 26 moves, and the common fixing frame 26 moves with multiple vertical frames 24 to slide inside the slot 9. The vertical frame 24 moves with the guide rod 11 and the slide plate 14 to slide at the same time. The guide rod 11 and the slide plate 14 slide and respectively bring the lower hole ring 12 and the upper hole ring 15 to slide at the same time. When one of the rollers 19 moves to the surface of the vertical rail 28, the lower hole ring 12 and the upper hole ring 15 move to the position corresponding to the hole 37, and the lower hole ring 12 and the upper hole ring 15 contact the top and bottom surfaces of the stacked file bags 3, and the bottom surface of the upper hole ring 15 is provided with a chamfer 36 (to prevent the upper hole ring 15 from squeezing the edge of the file bag 3). After the movement of the lower hole ring 12 and the upper hole ring 15 is completed, the lower hole ring 12 and the upper hole ring 15 have a slight clamping effect on the stacked file bags 3. As the lifting plate 16 continues to move down The lifting plate 16 moves downward, and multiple rollers 19 move on the surface of the vertical flat rail 8 and the surface of the vertical rail 28 respectively. The lifting plate 16 moves downward and also moves with multiple punches 18. The punches 18 move downward to punch holes in the stacked file bags 3. The lifting plate 16 of this scheme moves downward, and the lifting frame 17 and the rollers 19 move downward. The rollers 19 first squeeze the inclined rail 7 when they are squeezed. At this time, the multiple inclined rails 7 move in the middle with the front splint 4 and the two side splints 5 respectively. The stacked file bags 3 are clamped and fixed under the action of the front splint 4, the two side splints 5 and the fixed plate 6. The upper rail 27 moves after being squeezed, and moves with the common fixing frame 26. The common fixing frame 26 moves and drives multiple vertical frames 24 to slide inside the slot 9. The vertical frames 24 move and drive the guide rods 11 and the slide plate 14 to slide at the same time.The guide rod 11 and the slide plate 14 slide with the lower hole ring 12 and the upper hole ring 15 respectively, and the lower hole ring 12 and the upper hole ring 15 move to the position corresponding to the hole 37. The lower hole ring 12 and the upper hole ring 15 have a slight clamping effect on the stacked file bags 3. Compared with the traditional punching device, the device can complete the centering and positioning of the stacked file bags 3 during the punching process, and at the moment of punching, since the lower hole ring 12 and the upper hole ring 15 are in contact with the top and bottom surfaces of the stacked file bags 3, when the punch 18 punches the stacked file bags 3, the lower hole ring 12 and the upper hole ring 15 can effectively prevent the occurrence of depressions or cracks around the cut holes, which not only improves the punching machine body 1 The punching speed of the file bag 3 is increased, and the punching quality of the file bag 3 by the punch body 1 is also improved; according to the thickness of the file bag 3, the switch door 39 is opened, and the handle 34 is held to push and pull. At this time, the spacing tooth plate 31 moves and drives the adjustment gear 30 to rotate. The rotation of the adjustment gear 30 drives the rotating shaft 29 to rotate, causing the screw rod 25 to rotate, thereby causing the slide plate 14 to move inside the vertical frame 24. At the same time, the slide plate 14 slides up and down in the slide groove 13, realizing the adjustment of the spacing between the lower hole ring 12 and the upper hole ring 15. The spacing between the lower hole ring 12 and the upper hole ring 15 is suitable for the thickness of the stacked file bags 3 to be punched, and the punch body 1 can punch file bags 3 of different stacked thicknesses, thereby increasing the practicality of the device.

A rotating gear 43 is rotatably connected between the two supports 42. A chip removal rod 44 is slidably connected to the inside of any punch 18 for pushing the paper scraps inside it. The surface of the chip removal rod 44 is provided with a tooth groove 45 that meshes with the rotating gear 43. A fixing frame 47 is fixedly installed on the surface of the two supports 42. A lifting tooth plate 46 that meshes with the rotating gear 43 is provided on one side of the rotating gear 43. Lifting grooves 48 that match the fixing frame 47 are provided on both sides of the lifting tooth plate 46. A fourth spring 49 is elastically connected between the fixing frame 47 and the lifting groove 48. A ball head 50 is fixedly installed on the bottom surface of the lifting tooth plate 46. When the hole puncher 18 moves downward to punch the file bag 3, when the hole puncher 18 passes through the lower hole ring 12 and the upper hole ring 15 to punch the file bag 3, there will be paper scraps inside the hole puncher 18. As the hole puncher 18 continues to move downward to pass through the hole 37, the ball head 50 contacts the surface of the file bag 3 and is squeezed. The lifting gear plate 46 moves upward to squeeze the fourth spring 49, and at the same time drives the rotating gear 43 to rotate. The rotating gear 43 rotates and drives the chip discharge rod 44 to move downward in the hole puncher 18. The chip discharge rod 44 moves to push out the paper scraps inside the hole puncher 18. The pushed out paper scraps fall into the paper scrap box 51 for collection, preventing the paper scraps from being directly scattered on the surface of the file bag 3 and the work surface, thereby ensuring the cleanliness of the surface of the file bag 3 and the work surface.

[0048] The steps of using the present invention are as follows: when the automatic alignment punching machine for file binding is in use, since the punch 18 is designed as a circular knife, the punch 18 moves downward to punch the file bag 3. When the punch 18 passes through the lower hole ring 12 and the upper hole ring 15 to punch the file bag 3, there will be paper scraps inside the punch 18. As the punch 18 continues to move downward to pass through the hole 37, the ball head 50 contacts the surface of the file bag 3 and is squeezed. The lifting gear plate 46 moves upward to squeeze the fourth spring 49, and at the same time drives the rotating gear 43 to rotate. The rotating gear 43 rotates and drives the chip discharge rod 44 to move downward in the punch 18. The chip discharge rod 44 moves to push out the paper scraps inside the punch 18. The pushed out paper scraps fall into the paper scrap box 51 for collection, preventing the paper scraps from being directly scattered on the surface of the file bag 3 and the work surface, thereby ensuring the cleanliness of the surface of the file bag 3 and the work surface.
