Description

Technical Field

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

[0002] Archives management and preservation are of vital importance to all types of institutions. Binding, as the final key link in archive organization, is directly related to the regularity, firmness, ease of access and long-term preservation of the archives. Among them, thread-bound archives are still widely used in important archives, historical documents and other fields that need to be preserved for a long time because of their high firmness, good durability, relatively low cost and not easy to age and fall off.

[0003] When binding thread-bound files, the user stacks the organized files on the work surface, positions them, starts the machine, and presses down the drill bit group at the same time to drill through holes on the edge of the files. Then, the user uses binding wire to pass through the holes and manually bind and secure them.

[0004] However, the drilling device of this type of binding machine usually has a pre-set and fixed hole spacing between the punches, which means that the same device can only drill a combination of holes with a fixed center distance. If the thickness of the file exceeds the design adaptation range, the fixed hole spacing may not provide sufficient support span and binding tension, resulting in the middle of the file being loose, bulging outward and uneven after binding, which significantly reduces the stability of the overall structure and the tightness of the bonding between the papers. As a result, the file is loose and prone to falling apart, and may even cause the paper to tear near the edge of the spine. Summary of the Invention

[0020] (2) By setting up a servo motor, a first bidirectional threaded rod and a connecting plate and other structures, the position of the circular pressure plate is adjusted, which drives the top line block to move synchronously, and by starting the first electric telescopic rod to make it rise, the binding line is lifted and passed through the file hole, achieving the effect of assisting threading and facilitating manual bundling; at the same time, the paper scraps generated during the punching process are collected by the limit frame into the recycling box, achieving the effect of reducing the workload of manual cleaning.

[0021] (3) By setting up structures such as alignment plates, adjustment rods, slides, rollers and spring coils, in order to avoid the problem that the blank area at the edge of the hole is inconsistent due to the file not being in the center of the processing table, which in turn causes problems such as unsightly appearance and uneven distribution of binding lines after binding, the driving mechanism uses a belt transmission structure to drive the third bidirectional threaded rod to rotate, and uses a transmission belt to realize the process of the limit seat and the push plate moving closer to the middle, thereby realizing the automatic centering operation of the file, ensuring that the hole position is centered and the blank area is uniform, thereby improving the appearance quality of the binding.

[0043] The following describes in detail a multi-mode adjustable file binder provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0044] like Figures 1 to 7 As shown, an embodiment of the present invention provides a multi-mode adjustable file binding machine, comprising a box body 1, a wire trough 2 is provided 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 interior of the protective frame 9, a punching mechanism 12 is provided on 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 provided on the rear side of the partition plate 10; a fixing mechanism 5 for determining the file holes is provided 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; a driving mechanism 4 is provided on the inner top of the box body 1;

[0045] 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 two-way threaded rod 44 is rotatably connected to the inside of the first limit frame 41. One end of the first two-way threaded rod 44 passes through the first limit frame 41 and is fixedly connected to the box body 1 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 two-way threaded rod 44 are provided on both sides of the first sleeve. 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 provided on the side of the first two-way threaded rod 44 close to the servo motor 45, and a receiving component used in conjunction with the transmission mechanism 13 is provided on one side of the punching mechanism 12.

[0046] In order to solve the problem that the traditional binding machine cannot provide sufficient support span and binding tension for thicker files due to the fixed hole spacing between the punches, resulting in the middle part of the file being loose, bulging outward and uneven after binding, which is loose and not firm, and easily loose pages, or even causing paper to tear near the edge of the spine, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution mainly consists of a driving mechanism 4, a transmission mechanism 13, and a receiving assembly. When binding the 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 reverse, and the servo motor 45 is used to drive the first bidirectional threaded rod 44 to rotate; and during the rotation of the first bidirectional threaded rod 44, since the first sleeve is fixed to the middle part of the first limiting 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, so the first T-shaped slide 47 connected to it in the middle position and the fixing mechanism 5 part thereon (i.e., the middle circular pressure plate 57) are fixed in position. At the same time, since the threads on both sides of the first bidirectional threaded rod 44 rotate in opposite directions, when it rotates, the first threaded sleeves 46 on both sides move synchronously toward or away from each other along the axial direction of the first bidirectional threaded rod 44 under the limiting and guiding action of the first T-shaped slide 47 and the second limiting groove 43, and the first T-shaped slide 47 is used to drive the fixing mechanism 5 fixed thereon to move, thereby adjusting the distance between adjacent circular pressure 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 when the servo motor 45 drives the first bidirectional threaded rod 44 to rotate to adjust the spacing between the circular pressure plates 57, the rotational power of the first bidirectional threaded rod 44 is synchronously transmitted to the adjustment mechanism inside the punching mechanism 12 through the transmission mechanism 13 and the receiving assembly thereon. This driving The movement causes the multiple punches 129 in the punching mechanism 12 to move synchronously toward or away from each other, and dynamically adjust the hole spacing between adjacent punches 129. During this operation, for thicker files, the hole spacing of the punches 129 can be increased through this linkage adjustment, providing a larger effective support span for thick files, significantly increasing the effective coverage of the binding line in the middle of the file spine, ensuring that the binding line tension can be more evenly distributed on more paper layers, thereby providing a stronger restraining force to firmly "bundle" the middle area of ​​the file; at the same time, by enhancing the restraining force in the middle, the loosening and outward bulging deformation of the middle part of the file after binding is effectively prevented, and the overall flatness of the bound file is significantly improved; and for thinner files, the hole spacing of the punches can be reduced, significantly reducing the local stress at the edge of a single hole, and effectively avoiding paper tearing.After the spacing between the circular pressure plates 57 and the hole spacing between the punching needles 129 are adjusted to the correct position, the circular pressure plate 57 of the fixing mechanism 5 is pressed down to firmly press the edge of the file on the processing table 3. The center hole of the circular pressure plate 57 usually corresponds to the preset punching point position. Before starting the punching operation, the power connection between the transmission mechanism 13 and the punching mechanism 12 is disconnected by operating the receiving assembly, and the cylinder 11 is started to retract its piston rod, driving the U-shaped plate 111 and the entire punching mechanism 12 fixed thereon to move downward, and the punching needle 129 is used to pass through the center hole of the circular pressure plate 57 to perform a punching operation on the edge of the file fixed below.

[0047] like Figure 1 、 Figure 3 、 Figure 5 As shown, the punching mechanism 12 includes a second limit frame 121 fixedly connected to the front end of the U-shaped plate 111, and a slide groove 122 is provided at the bottom of the second limit frame 121. The second limit frame 121 is internally rotatably connected to a second bidirectional threaded rod 123, and one side of the outer cylindrical surface of the second bidirectional threaded rod 123 is fixedly connected to a first baffle 124, and one end of the second bidirectional threaded rod 123 passes through the second limit frame 121 and is fixedly connected to the second baffle 125; the middle of the second limit frame 121 is fixedly connected to a second sleeve, and second threaded sleeves 126 meshing with the second bidirectional threaded rod 123 are provided on both sides of the second sleeve, and the second threaded sleeve 126 and the bottom of the second sleeve are fixedly connected to a second T-shaped slide 127, the second T-shaped slide 127 passes through the slide groove 122 and is fixedly connected to the limiting cylinder 128, and the internal thread of the limiting cylinder 128 is connected to the punching needle 129.

[0048] like Figure 4 、 Figure 5 As shown, the receiving assembly 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, and one side of the outer surface of the box body 1 is fixedly connected to a tripod 8 for supporting the servo motor 45 and the transmission mechanism 13, and the transmission mechanism 13 includes a fixed seat 131 fixedly connected to one side of the top of the tripod 8, and the internal rotation connection of the fixed seat 131 is connected to a receiving tube 132, and the interior of the receiving tube 132 is provided with a card slot 133 adapted to the receiving block 141, and both sides of the outer surface of the fixed seat 131 are provided with partitions 134 fixedly connected to the receiving tube 132, and a first pulley 135 is fixedly connected to the middle of the outer circumferential surface of the receiving tube 132, and a second pulley 136 is fixedly connected to the side of the first bidirectional threaded rod 44 close to the servo motor 45, and a belt 137 is commonly sleeved on the outer surface of the second pulley 136 and the first pulley 135.

[0049] In the process of using the servo motor 45 to drive the first bidirectional threaded rod 44 to rotate, the second pulley 136 fixedly connected thereto drives the first pulley 135 to rotate synchronously with the belt 137, so that the receiving tube 132 rotates in the fixed seat 131 and the tripod 8 under the limiting action of the partition 134; and because the receiving block 141 is stuck in the internal slot 133 of the receiving tube 132 when the second electric telescopic rod 14 is extended, the receiving block 141 drives the receiving block 141 and the second electric telescopic rod 14 to rotate synchronously, thereby causing the second bidirectional threaded rod 123 to rotate between the first baffle 124 and the second baffle Under the limiting action of 125, it rotates in the second limiting frame 121, so that the second threaded sleeve 126 drives the second T-shaped slide 127 to move synchronously toward or away from each other along the slide groove 122, and makes multiple punches 129 move synchronously toward or away from each other, dynamically adjusts the hole distance between adjacent punches 129, so as to increase or decrease the hole distance of the punches 129, and provides an effective support span for files of different thicknesses or widths. By strengthening the restraining force in the middle, it effectively prevents the loosening and outward bulging deformation of the middle part of the file after binding, significantly improves the overall flatness of the bound file, reduces the local stress at the edge of a single hole, and effectively avoids paper tearing. After the hole spacing adjustment is completed, when it is necessary to perform a punching operation on the file, the servo motor 45 is stopped and the second electric telescopic rod 14 is started again to retract, so that the receiving block 141 is disengaged from the card slot 133 and the receiving tube 132 is contacted to drive the receiving block 141 to a limited position. Then, the cylinder 11 is started to retract its piston rod to an appropriate length, driving the U-shaped plate 111 and the entire punching mechanism 12 fixed thereon to move downward, and the punching needle 129 is used to pass through the center hole of the circular pressure plate 57 to perform a punching operation on the edge of the file fixed below.

[0050] like Figure 4 、 Figure 6 、 Figure 7 As shown, the fixing mechanism 5 also includes a limiting rod 51 fixedly connected to one side of the top of the first T-shaped slide 47, the top of the limiting rod 51 is fixedly connected to a fixing plate 52, the internal rotation of the fixing plate 52 is connected to an adjusting rod 53, the outer cylindrical surface of the adjusting rod 53 is threadedly connected to a threaded sleeve 55, the bottom of the threaded sleeve 55 is fixedly connected to a slide 54, and one side of the inside of the slide 54 is sleeved on the adjusting rod 53 for limiting; one side of the outer surface of the slide 54 is fixedly connected to a first support arm 56, and one end of the first support arm 56 is fixedly connected to a circular pressure plate 57.

[0051] like Figure 4 、 Figure 5 、 Figure 6As shown, the first bidirectional threaded rod 44 and the second bidirectional threaded rod 123 have the same structure and function, and thread rings with the same pitch are provided on both sides of the outer cylindrical surface, so that the first bidirectional threaded rod 44 and the second bidirectional threaded rod 123 can rotate synchronously through the servo motor 45, the transmission mechanism 13, and the supporting component, thereby adjusting the punching position to complete the hole spacing adjustment.

[0052] During the rotation of the first bidirectional threaded rod 44, the first threaded sleeve 46 drives the first T-shaped slide 47 to move synchronously toward or away from the second limiting groove 43, and uses the first T-shaped slide 47 to drive the fixing mechanism 5 fixed thereon to move, thereby adjusting the distance between adjacent circular ring pressure plates 57 to make it 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 when the punching operation is required, it is only necessary 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 the first support arm 56 and the circular ring pressure plate 57 that are fixedly connected move downward synchronously, thereby using the downward pressure of the first support arm 56 and the circular ring pressure plate 57 to fix the file on the processing table 3, thereby ensuring that the side of the file that needs to be bound is fixed will not be offset, further making the punching more stable. In the process of adjusting the annular pressure plate 57 by using the servo motor 45 and the first bidirectional threaded rod 44, the transmission mechanism 13 and the receiving assembly are used to make the second bidirectional threaded rod 123 for adjusting the position of the punching needle 129 rotate synchronously, thereby synchronously adjusting the hole distance position.

[0053] like Figure 4 、 Figure 6 As shown, the driving mechanism 4 also includes a connecting plate 48 fixedly connected to the first threaded sleeve 46 and the first sleeve seat, a first limiting groove 42 is opened on one side of the outer surface of the first limiting frame 41, the connecting plate 48 passes through the first limiting groove 42 and is fixedly connected to the top line assembly 7, the top line assembly 7 includes a support plate 71 fixedly connected to one side of the connecting plate 48, the upper surface of the support plate 71 is fixedly connected to the first electric telescopic rod 72, and the top of the first electric telescopic rod 72 is fixedly connected to the top of the top line block 73.

[0054] like Figure 1 、 Figure 2 As shown, an alignment plate 33 is fixedly connected to one side of the upper surface of the processing table 3, and a U-shaped groove is provided inside the alignment plate 33 to facilitate the movement of the first arm 56; the processing table 3 is provided with a threading groove 31 directly below the punching needle 129, and the threading groove 31 is directly above the top line block 73, so that the first electric telescopic rod 72 can be used to drive the top line block 73 to lift the binding line inside the wire groove 2 to complete the top line operation.

[0055] like Figure 2As shown, the inner bottom of the box body 1 is fixedly connected to a limit frame 15, and the inner bottom of the limit frame 15 is slidably connected to a recovery box 16 for recovering debris.

[0056] In the process of adjusting the position of the annular pressure plate 57 by using the servo motor 45 and the first bidirectional threaded rod 44, the first threaded sleeve 46 moves synchronously in the first limit groove 42 by using the connecting plate 48, and drives the support plate 71, the first electric telescopic rod 72 and the top line clamping block 73 to move synchronously; and after the punching of the file is completed by using the punching needle 129, it is only necessary to start the first electric telescopic rod 72 to extend it, so that the top line clamping block 73 rises synchronously, and use the storage slot at the top of the top line clamping block 73 to lift the binding wire in the wire groove 2 and pass it through the hole of the file from the threading groove 31, so that the operator can manually bind 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; in the process, the paper scraps generated during the punching process with the punching needle 129 are uniformly collected in the recycling box 16 through the limit frame 15, reducing the workload of manual cleaning.

[0057] like Figure 1 、 Figure 2 As shown, a symmetrical fixing groove 32 is provided in the middle of the upper surface of the processing table 3, and a positioning mechanism 17 for assisting file centering is provided inside the fixing groove 32. The positioning mechanism 17 includes a third bidirectional threaded rod 171 rotatably connected to the inside of the box body 1, and both ends of the third bidirectional threaded rod 171 are provided with a limit seat 172 fixedly connected to the box body 1. One end of the third bidirectional threaded rod 171 is fixedly connected to the first fixed wheel 173, and the other end of the first bidirectional threaded rod 44 is fixedly connected to the second fixed wheel 174. The outer circumferential surfaces of the first fixed wheel 173 and the second fixed wheel 174 are jointly sleeved with a transmission belt 175. Both sides of the outer circumferential surface of the third bidirectional threaded rod 171 are threadedly connected with an adjustment seat 176, and the adjustment seat 176 passes through the fixing groove 32 and is fixedly connected to a push plate 177.

[0058] like Figure 6 、 Figure 7 As shown, an auxiliary limiting mechanism 6 is provided on one side of the outer circular surface of the circular pressure plate 57, and the auxiliary limiting mechanism 6 includes a second arm 61 fixedly connected to one side of the outer circular surface of the circular pressure plate 57, and a top plate 62 is placed on the upper surface of the second arm 61, and both sides of the bottom of the top plate 62 are fixedly connected with a fixing rod 63, and the fixing rod 63 passes through the second arm 61 and is fixedly connected to the bottom plate, and the upper surface of the bottom plate is provided with a limiting sleeve 64 that is slidingly connected to the fixing rod 63, and the outer circular surface of the fixing rod 63 is sleeved with a spring ring 65, and the internal rotation of the limiting sleeve 64 is connected to the support rod 66, and the middle of the outer circular surface of the support rod 66 is fixedly connected to the roller 67.

[0059] When punching files, in order to avoid the problem of inconsistent blank areas on the edges of the holes due to the file not being in the center of the processing table 3, which will cause problems such as unsightly appearance and uneven distribution of binding lines after binding; 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 adjusting rod 53 to make the threaded sleeve 55 drive the slide 54 to move downward under the guidance of the limit rod 51, and the first arm 56 and the circular pressure plate 57 fixedly connected to the slide 54 will also move downward synchronously; in this process, the second arm 61 also moves downward accordingly, and when the roller 67 installed thereon contacts the upper surface of the file, stop rotating the adjusting rod 53. At this time, the spring coil 65 applies elastic pressure to push The limit sleeve 64 is moved to keep the roller 67 at a stable height, thereby preventing the files from loosening during the subsequent centering process. At the same time, the driving mechanism 4 is started, so that the first bidirectional threaded rod 44 causes the second fixed wheel 174 to rotate, and the transmission belt 175 is used to make the first fixed wheel 173 drive the third bidirectional threaded rod 171 to rotate synchronously, so that the limit seat 172 moves toward the center along the fixed groove 32, and then the push plate 177 moves toward the center, realizing the automatic centering operation of the files on the processing table 3. During this centering process, the roller 67 will drive the support rod 66 to rotate flexibly in the limit sleeve 64, and at the same time rely on the elastic force of the spring coil 65 to maintain pressure on the files, further preventing the papers from being misplaced or scattered. In addition, while performing the centering operation, the system is also adjusting the hole pitch. Since the pitch of the third bidirectional threaded rod 171 is smaller than the pitch of the first bidirectional threaded rod 44, during the adjustment process, the annular pressure plate 57 and the punch 129 for fixing the file can be accurately stopped between the two push plates 177, ensuring that accurate punching operations can be performed immediately after the centering is completed, thereby improving work efficiency and punching accuracy.

[0060] When the present invention is in use, one side of the file to be bound is first placed on the processing table 3 and aligned with the alignment plate 33 to ensure that the initial position is accurate. 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 limit 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 during subsequent operations; 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 since the first T-shaped slide 47 is sleeved on the non-threaded section and fixed in the middle of the first limit frame 41, its position remains unchanged, and the first threaded sleeves 46 on both sides are aligned along the axial direction under the guidance of the second limit groove 43. The second punching pins 129 are moved toward or away from each other, thereby driving the circular pressure plate 57 fixed thereon to move synchronously, adjusting the spacing to match the actual width of the current file, and ensuring that the punching position is accurately positioned; 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 multiple 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 from being loose or 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 adjusting rod 53 to further press the annular pressure plate 57 downward, firmly pressing the file on the processing table 3 to prevent deviation during the punching process. Subsequently, the receiving assembly is operated to disconnect the power connection between the transmission mechanism 13 and the punching mechanism 12, and then the cylinder 11 is started to retract its piston rod, driving the U-shaped plate 111 and the entire punching mechanism 12 to move downward, and the punching needle 129 is used to pass through the center hole of the annular pressure plate 57 to perform a punching operation on the fixed file. After the punching is completed, the first electric telescopic rod 72 is started to drive the top line block 73 to rise, lift the binding wire in the wire groove 2, and pass it through the file hole from the wire groove 31, which is convenient for manual bundling and improves the binding efficiency and stability. The paper scraps generated during the punching process are uniformly collected in the recycling box 16 by the limit frame 15, reducing the workload of manual cleaning.
