Description

Technical Field

[0001] The present invention relates to the technical field of file binding, and more specifically, to a multi-mode adjustable file binding machine. Background Art

[0002] File management and preservation are crucial for various institutions. Binding, as the last key link in file sorting, is directly related to the neatness, firmness, convenience of access, and long-term preservation effect of files. Among them, thread-bound files are still widely used in important files that need to be preserved for a long time, historical documents, etc. due to their high firmness, good durability, relatively low cost, and resistance to aging and shedding.

[0003] When binding thread-bound files, the user stacks the sorted files on the workbench for positioning, starts the machine, and the drill bit group presses down simultaneously to drill through holes at the edge of the files. Subsequently, binding threads are used to pass through the holes for manual bundling and fixing.

[0004] However, for the drilling device of such binding machines, the hole distance between the punch needles is usually preset and fixed. This means that the same device can only drill a combination of holes with a fixed center distance. If the thickness of the files exceeds the designed adaptation range, the fixed hole distance may not provide sufficient support span and bundling tension, resulting in a loose, outwardly bulging non-flat shape in the middle of the bound files, significantly reducing the stability of the overall structure and the tightness of the binding between the papers. Therefore, they are loose and not firm, prone to page scattering, and even cause tearing of the papers near the spine at the edge. Summary of the Invention

[0024] The following is a detailed description of a multi-mode adjustable file binder provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 7 As shown, an embodiment of the present invention provides a multi-mode adjustable file binding machine, including a box body 1, a wire placing groove 2 is opened inside the box body 1, a processing table 3 is fixedly connected to one side of the upper surface of the box body 1, a protective frame 9 is fixedly connected to the other side of the upper surface of the box body 1, a partition plate 10 is fixedly connected to the inside of the protective frame 9, a punching mechanism 12 is arranged at the inner top of the protective frame 9, and a cylinder 11 and a U-shaped plate 111 for adjusting the height of the punching mechanism 12 are arranged at the rear side of the partition plate 10; a fixing mechanism 5 for determining the file hole is arranged on the side of the processing table 3 close to the protective frame 9, and the fixing mechanism 5 includes a circular pressing plate 57 for pressing and fixing the file before punching, and a driving mechanism 4 is arranged at the inner top of the box body 1; Among them, the driving mechanism 4 includes a first limit frame 41 fixedly connected to the top of the box body 1, a second limit groove 43 is opened on the top of the first limit frame 41, and the first limit frame 41 is internally rotatably connected with a first bidirectional threaded rod 44, one end of the first bidirectional threaded rod 44 passes through the first limit frame 41, and the box body 1 is fixedly connected with a servo motor 45, a first sleeve is fixedly connected to the middle of the first limit frame 41, and first threaded sleeves 46 meshing with the first bidirectional threaded rod 44 are arranged on both sides of the first sleeve, and the first threaded sleeve 46 and the top of the first sleeve are fixedly connected with a first T-shaped slide 47 for supporting the fixing mechanism 5; a transmission mechanism 13 is arranged on the side of the first bidirectional threaded rod 44 close to the servo motor 45, and a receiving component used in conjunction with the transmission mechanism 13 is arranged on one side of the punching mechanism 12.

[0026] To solve the problem that the traditional binding machine has a fixed hole distance between the punching needles, which cannot provide enough support span and bundling tension for thicker files, resulting in a loose, outwardly bulging non-flat shape in the middle of the bound file, so that the file is loose and not firm, easy to fall apart, and even cause paper tearing at the spine near the edge. Now, the above technical solution is adopted to solve this problem. The above technical solution mainly consists of a driving mechanism 4, a transmission mechanism 13, and a receiving component. When binding a file, one side of the file to be bound, usually the binding edge, is placed on the processing table 3. According to the actual width of the file, the servo motor 45 is started to rotate forward or backward, and the servo motor 45 is used to drive the first bidirectional threaded rod 44 to rotate. During the rotation of the first bidirectional threaded rod 44, since the first seat is fixed in the middle of the first limit frame 41 and sleeved in the middle of the first bidirectional threaded rod 44 (non-threaded section or fixed connection point), its position remains unchanged. Therefore, the first T-shaped slider 47 at the middle position connected to it and the fixed mechanism 5 part thereon (i.e., the middle circular ring pressing plate 57) are fixed in position. At the same time, since the thread directions on both sides of the first bidirectional threaded rod 44 are opposite, when it rotates, the first thread sleeves 46 on both sides move synchronously towards or away from each other along the axis direction of the first bidirectional threaded rod 44 under the limiting and guiding action of the first T-shaped slider 47 and the second limit groove 43, and drive the fixed mechanism 5 part fixed on the first T-shaped slider 47 to move, thereby adjusting the distance between adjacent circular ring pressing plates 57 to accurately match the width of the current file. This step ensures the accurate positioning of the punching position along the width direction of the file. And while the servo motor 45 drives the first bidirectional threaded rod 44 to rotate to adjust the distance between the circular ring pressing plates 57, through the transmission mechanism 13 and the receiving component thereon, the rotational power of the first bidirectional threaded rod 44 is synchronously transmitted to the adjustment mechanism inside the punching mechanism 12. This drive makes the multiple punching needles 129 in the punching mechanism 12 move synchronously towards or away from each other, dynamically adjusting the hole distance between adjacent punching needles 129. During this operation process, for thicker files, the hole distance of the punching needles 129 can be increased through this linkage adjustment, providing a larger effective support span for the thick files, significantly increasing the effective coverage range of the binding line in the middle of the file spine, ensuring that the binding line tension can be more evenly distributed to more paper layers, thereby providing stronger binding force to firmly "bundle" the middle area of the file; at the same time, by enhancing the binding force in the middle, effectively preventing the loosening and outward bulging deformation of the middle of the bound file, significantly improving the overall flatness of the bound file; for thinner files, the hole distance of the punching needles can be reduced, significantly reducing the local stress at the edge of a single hole, effectively avoiding paper tearing.After the distances between the circular ring pressing plate 57 and the hole distances of the punching pins 129 are both adjusted in place, the circular ring pressing plate 57 of the fixing mechanism 5 is pressed down to firmly press the edge of the file on the processing table 3. The central hole of the circular ring pressing plate 57 usually corresponds to the preset punching point position. Before starting the punching operation, by operating the receiving component, the power connection between the transmission mechanism 13 and the punching mechanism 12 is disconnected, and the air cylinder 11 is started, causing its piston rod to contract, driving the U-shaped plate 111 and the entire punching mechanism 12 fixed thereon to move downward. The punching pin 129 is used to pass through the central hole of the circular ring pressing plate 57 to perform a punching operation on the edge of the file that has been fixed below. As Figure 1 , Figure 3 , Figure 5 shown, the punching mechanism 12 includes a second limiting frame 121 fixedly connected to the front end of the U-shaped plate 111. A chute 122 is provided at the bottom of the second limiting frame 121. A second bidirectional threaded rod 123 is rotatably connected inside the second limiting frame 121. A first baffle 124 is fixedly connected to one side of the outer cylindrical surface of the second bidirectional threaded rod 123, and one end of the second bidirectional threaded rod 123 penetrates through the second limiting frame 121 and is fixedly connected to a second baffle 125. A second socket is fixedly connected to the middle of the second limiting frame 121, and second threaded sleeves 126 engaged with the second bidirectional threaded rod 123 are provided on both sides of the second socket. Second T-shaped sliding seats 127 are fixedly connected to the bottoms of the second threaded sleeves 126 and the second socket. The second T-shaped sliding seats 127 penetrate through the chute 122 and are fixedly connected to a limiting cylinder 128. A punching pin 129 is threadedly connected inside the limiting cylinder 128.

[0027] As Figure 4 , Figure 5 shown, the receiving component includes a second electric telescopic rod 14 fixedly connected to the outside of the second baffle 125. One end of the second electric telescopic rod 14 is fixedly connected to a receiving block 141. A triangular bracket 8 for supporting the servo motor 45 and the transmission mechanism 13 is fixedly connected to one side of the outer surface of the box body 1. The transmission mechanism 13 includes a fixed seat 131 fixedly connected to one side of the top of the triangular bracket 8. A receiving pipe 132 is rotatably connected inside the fixed seat 131. A slot 133 adapted to the receiving block 141 is provided inside the receiving pipe 132. Partition plates 134 fixedly connected to the receiving pipe 132 are provided on both sides of the outer surface of the fixed seat 131. A first pulley 135 is fixedly connected to the middle of the outer cylindrical surface of the receiving pipe 132. A second pulley 136 is fixedly connected to one side of the first bidirectional threaded rod 44 close to the servo motor 45. A belt 137 is sleeved on the outer surfaces of the second pulley 136 and the first pulley 135.

[0028] During the process of driving the first bidirectional threaded rod 44 to rotate by using the servo motor 45, the second pulley 136 fixedly connected thereto drives the first pulley 135 to rotate synchronously by using the belt 137, so that the receiving pipe 132 rotates within the fixed seat 131 and the triangular frame 8 under the limiting effect of the partition plate 134; and when the second electric telescopic rod 14 extends, the receiving block 141 is stuck in the internal card slot 133 of the receiving pipe 132, so that the receiving pipe 132 drives the receiving block 141 and the second electric telescopic rod 14 to rotate synchronously, and further enables the second bidirectional threaded rod 123 to rotate within the second limiting frame 121 under the limiting effect of the first baffle 124 and the second baffle 125, so that the second thread sleeve 126 drives the second T-shaped sliding seat 127 to move synchronously towards or away from each other along the sliding groove 122, and enables a plurality of punching needles 129 to move synchronously towards or away from each other, dynamically adjusting the hole distance between adjacent punching needles 129, increasing or decreasing the hole distance of the punching needles 129, providing an effective support span for files of different thicknesses or widths, effectively preventing the middle part of the bound file from being loose and bulging outwards by enhancing the binding force in the middle part, significantly improving the overall flatness of the bound file, reducing the local stress at the edge of a single hole, and effectively avoiding paper tearing. After the hole distance adjustment is completed and when the file needs to be punched, stop the operation of the servo motor 45, start the second electric telescopic rod 14 again, and make it contract, so that the receiving block 141 disengages from the card slot 133, and the limiting drive of the receiving pipe 132 on the receiving block 141 is released. Then, by starting the cylinder 11 and making its piston rod contract to an appropriate length, drive the U-shaped plate 111 and the entire punching mechanism 12 fixed thereon to move downwards, and use the punching needles 129 to pass through the central hole of the circular pressing plate 57 to punch the edge of the file fixed below.

[0029] As Figure 4 , Figure 6 , Figure 7 shown, the fixing mechanism 5 further includes a limiting rod 51 fixedly connected to one side of the top of the first T-shaped sliding seat 47. The top of the limiting rod 51 is fixedly connected with a fixing plate 52. An adjusting rod 53 is rotatably connected inside the fixing plate 52. A threaded sleeve 55 is threadedly connected to the outer circumferential surface of the adjusting rod 53. The bottom of the threaded sleeve 55 is fixedly connected with a sliding seat 54, and one side inside the sliding seat 54 is sleeved on the adjusting rod 53 for limiting; one side of the outer surface of the sliding seat 54 is fixedly connected with a first arm 56, and one end of the first arm 56 is fixedly connected with a circular pressing plate 57.

[0030] As Figure 4 , Figure 5 , Figure 6As shown, the structures and functions of the first double-threaded rod 44 and the second double-threaded rod 123 are the same, and thread coils with the same pitch are provided on both sides of the outer cylindrical surface, so as to synchronously rotate the first double-threaded rod 44 and the second double-threaded rod 123 through the servo motor 45, the transmission mechanism 13, and in cooperation with the receiving assembly, thereby adjusting the punching position to complete the hole pitch adjustment.

[0031] During the rotation of the first double-threaded rod 44, the first thread sleeve 46 drives the first T-shaped slide 47 to move synchronously towards or away from each other along the second limiting groove 43, and uses the first T-shaped slide 47 to drive the fixed mechanism 5 fixed thereon to move partially, thereby adjusting the distance between adjacent circular pressing plates 57 to accurately match the width of the current file. This step ensures the accurate positioning of the punching position along the width direction of the file; when punching is required, only need to rotate the adjusting rod 53 according to the thickness of the file, so that the threaded sleeve 55 drives the slide 54 to move downward under the action of the limiting rod 51, and makes the fixedly connected first arm 56 and the circular pressing plate 57 move downward synchronously, thereby using the downward pressure of the first arm 56 and the circular pressing plate 57 to fix the file on the processing table 3, so as to ensure that the side of the file to be bound will not shift in position after being fixed, and further make the punching more stable. And during the process of adjusting the circular pressing plate 57 by using the servo motor 45 and the first double-threaded rod 44, the second double-threaded rod 123 for adjusting the position of the punching needle 129 is synchronously rotated by using the transmission mechanism 13 and the receiving assembly, thereby synchronously adjusting the hole pitch position.

[0032] As Figure 4 、 Figure 6 shown, the driving mechanism 4 further includes a connecting plate 48 fixedly connected to the first thread sleeve 46 and the first socket. A first limiting groove 42 is provided on one side of the outer surface of the first limiting frame 41. The connecting plate 48 penetrates through the first limiting groove 42 and is fixedly connected with a thread topping component 7. The thread topping component 7 includes a support plate 71 fixedly connected to one side of the connecting plate 48. A first electric telescopic rod 72 is fixedly connected to the upper surface of the support plate 71. The top of the first electric telescopic rod 72 is fixedly connected with a thread topping block 73.

[0033] As Figure 1 、 Figure 2 shown, an alignment plate 33 is fixedly connected to one side of the upper surface of the processing table 3. A U-shaped notch for the first arm 56 to move is provided inside the alignment plate 33; a thread passing groove 31 is provided directly below the punching needle 129 on the processing table 3, and the thread passing groove 31 is directly above the thread topping block 73, so as to use the first electric telescopic rod 72 to drive the thread topping block 73 to lift the binding thread inside the thread releasing groove 2 to complete the thread topping operation.

[0034] As Figure 2As shown, a limiting frame 15 is fixedly connected to the inner bottom of the box body 1, and a recycling box 16 for recycling debris is slidably connected to the inner bottom of the limiting frame 15.

[0035] During the process of adjusting the position of the circular pressing plate 57 by using the servo motor 45 and the first bidirectional threaded rod 44, the first threaded sleeve 46 synchronously moves in the first limiting groove 42 by using the connecting plate 48, and drives the support plate 71, the first electric telescopic rod 72 and the top wire clamping block 73 to move synchronously; and after the punching needle 129 completes punching the file, only need to start the first electric telescopic rod 72 to make it extend, so that the top wire clamping block 73 rises synchronously, and use the receiving slot at the inner top of the top wire clamping block 73 to lift the binding wire in the wire releasing groove 2 and pass through the hole of the file from the wire passing slot 31, so that the operator can manually bundle and fix the file with the binding wire passing through the hole of the file, ensuring that the bound file will not have loose pages; during this process, the paper scraps generated during the punching process with the punching needle 129 are uniformly collected in the recycling box 16 through the limiting frame 15, reducing the workload of manual cleaning.

[0036] As Figure 1 , Figure 2 shown, symmetric fixing grooves 32 are opened at the middle of the upper surface of the processing table 3, and a positioning mechanism 17 for assisting in file alignment is arranged inside the fixing grooves 32. The positioning mechanism 17 includes a third bidirectional threaded rod 171 rotatably connected to the inside of the box body 1. Limiting seats 172 fixedly connected to the box body 1 are arranged at both ends of the third bidirectional threaded rod 171. A first fixed wheel 173 is fixedly connected to one end of the third bidirectional threaded rod 171, a second fixed wheel 174 is fixedly connected to the other end of the first bidirectional threaded rod 44, a transmission belt 175 is sleeved on the outer circumferential surfaces of the first fixed wheel 173 and the second fixed wheel 174, and adjusting seats 176 are threadedly connected to both sides of the outer circumferential surface of the third bidirectional threaded rod 171. The adjusting seats 176 penetrate through the fixing grooves 32 and are fixedly connected with push plates 177.

[0037] As Figure 6 , Figure 7 shown, an auxiliary limiting mechanism 6 is arranged on one side of the outer circumferential surface of the circular pressing plate 57. The auxiliary limiting mechanism 6 includes a second arm 61 fixedly connected to one side of the outer circumferential surface of the circular pressing plate 57. A top plate 62 is placed on the upper surface of the second arm 61. Fixed rods 63 are fixedly connected to both sides of the bottom of the top plate 62. The fixed rods 63 penetrate through the second arm 61 and are fixedly connected with a bottom plate. A limiting sleeve seat 64 slidably connected to the fixed rods 63 is arranged on the upper surface of the bottom plate. A spring coil 65 is sleeved on the outer circumferential surface of the fixed rods 63. A support rod 66 is rotatably connected to the inside of the limiting sleeve seat 64. A roller 67 is fixedly connected to the middle of the outer circumferential surface of the support rod 66.

[0038] When performing the punching operation on the file, in order to avoid problems such as inconsistent blank areas at the edges of the holes caused by the file not being in the central position of the processing table 3, resulting in an unattractive appearance after binding and uneven distribution of the binding lines; first, align the side of the file to be bound with the alignment plate 33, and then, according to the thickness of the file, rotate the adjustment rod 53, so that the threaded sleeve 55 drives the sliding seat 54 to move downward under the guiding action of the limiting rod 51, and the first support arm 56 and the circular pressing plate 57 fixedly connected to the sliding seat 54 will also move downward synchronously; during this process, the second support arm 61 also moves downward accordingly. When the roller 67 mounted on it touches the upper surface of the file, stop rotating the adjustment rod 53. At this time, the spring ring 65 exerts an elastic pressure to push the limiting sleeve seat 64, so that the roller 67 maintains a stable height, thereby preventing the file from being scattered during the subsequent centering process; at the same time, start the driving mechanism 4, so that the first double-threaded rod 44 makes the second fixed wheel 174 rotate, and uses the transmission belt 175 to make the first fixed wheel 173 drive the third double-threaded rod 171 to rotate synchronously, so that the limiting seat 172 moves closer to the middle along the fixed groove 32, and then the push plate 177 moves closer to the middle, realizing the automatic centering operation of the file on the processing table 3; during this centering process, the roller 67 will drive the support rod 66 to rotate flexibly in the limiting sleeve seat 64, and at the same time rely on the elastic force of the spring ring 65 to maintain the pressure on the file, further preventing the paper from being misaligned or scattered. In addition, while performing the centering operation, the system is also adjusting the hole pitch. Since the pitch of the third double-threaded rod 171 is smaller than the pitch of the first double-threaded rod 44, during the adjustment process, the circular pressing plate 57 for fixing the file and the punching needle 129 can accurately stay between the two push plates 177, ensuring that accurate punching operations can be immediately performed after centering, thereby improving work efficiency and punching accuracy.

[0039] When the present invention is in use, firstly, one side of the file to be bound is placed on the processing table 3, and aligned with the alignment plate 33 to ensure the accuracy of the initial position. Then, according to the thickness of the file, the adjusting rod 53 is rotated to make the slide 54 move downward under the guidance of the limiting rod 51, driving the first arm 56 and the circular pressure plate 57 to move downward synchronously; at the same time, the roller 67 on the second arm 61 contacts the surface of the file, and maintains a stable pressure under the elastic pressure of the spring coil 65 to prevent the paper from being misplaced or scattered in the subsequent operation; next, the driving mechanism 4 is started, and the servo motor 45 drives the first bidirectional threaded rod 44 to rotate forward or reverse, and because the first T-shaped slide 47 is sleeved on the non-threaded section and fixed in the middle of the first limiting frame 41, its position remains unchanged, and the first threaded sleeves 46 on both sides are guided by the second limiting groove 43 along the axial direction. The plurality of punching pins 129 are moved toward or away from each other synchronously, thereby driving the circular pressure plate 57 fixed thereon to move synchronously, adjusting the spacing thereof to match the actual width of the current file, and ensuring accurate positioning of the punching position; at the same time, the power of the servo motor 45 is transmitted to the punching mechanism 12 through the transmission mechanism 13, and drives the second bidirectional threaded rod 123 to rotate through the receiving assembly, so that the second threaded sleeve 126 drives the second T-shaped slide 127 to move along the slide groove 122, and then drives the plurality of punching pins 129 to move toward or away from each other synchronously, and dynamically adjusts the hole spacing between adjacent punching pins 129: for thicker files, the hole spacing is increased to provide a larger support span, enhance the coverage and bundling force of the binding line in the middle area, and effectively prevent the middle part from being loose and bulging; for thinner files, the hole spacing is reduced to reduce the local stress at the edge of a single hole and avoid paper tearing. After completing the linkage adjustment of the hole spacing and the pressure plate spacing, continue to rotate the adjustment rod 53 to further press the annular pressure plate 57 downward, firmly press the file on the processing table 3 to prevent deviation during the punching process, then operate the receiving assembly to disconnect the power connection between the transmission mechanism 13 and the punching mechanism 12, and then start the cylinder 11 to shrink its piston rod, drive the U-shaped plate 111 and the entire punching mechanism 12 to move downward, and use the punch needle 129 to pass through the center hole of the annular pressure plate 57 to punch the fixed file; after the punching is completed, start the first electric telescopic rod 72 to drive the top line block 73 to rise, lift the binding line in the wire groove 2, and pass it through the file eyelet from the threading groove 31, so as to facilitate manual bundling, improve binding efficiency and stability, and the paper scraps generated during the punching process are uniformly collected into the recycling box 16 through the limit frame 15, so as to reduce the workload of manual cleaning.
