Description

Technical Field

[0001] This utility model relates to the field of binding machine technology, and mainly to a binding machine. Background Technology

[0002] Binding machines, as common office equipment, are widely used in the organization and binding of various documents and materials, playing a vital role in people's daily office work. However, traditional binding machines mostly use a purely manual punching method. This not only requires operators to exert considerable strength to complete the punching operation, but also consumes a lot of physical energy when processing large volumes of documents, resulting in low punching efficiency and failing to meet the needs of efficient document organization. In addition, operators are prone to fatigue from prolonged use of manual punching devices, which in turn affects the accuracy and consistency of punching, leading to inconsistent document binding quality and low efficiency.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a binding machine that solves the problems of labor-intensive and inefficient traditional manual punching binding machines.

[0006] This utility model provides a binding machine, including a frame, wherein the binding machine further includes a drive motor and a cutting tool assembly disposed on the frame; the drive motor is connected to the cutting tool assembly in a transmission manner, and the drive motor is used to drive the cutting tool assembly to move up and down to punch holes in the paper;

[0007] The binding machine also includes a pressing ring assembly disposed on the frame, the pressing ring assembly being used to press the binding ring together.

[0008] In this invention, a drive motor is mounted on the frame and connected to the cutter assembly. The drive motor drives the cutter assembly to move up and down. After paper is placed at the corresponding position, the cutter assembly moves downwards to punch holes in the paper. After punching, the cutter assembly moves upwards and withdraws from the punched holes, completing the punching operation. After punching, the binding ring is opened and inserted into the punched holes in the paper. Then, the binding ring is pressed and tightened by the provided pressure ring assembly, completing the binding operation.

[0009] Furthermore, the pressure ring assembly includes a second drive shaft, a pressure ring handle, a second synchronous gear, an L-shaped fixing plate, and an L-shaped pressure plate. The second drive shaft is rotatably mounted on the frame. The second drive shaft is coaxially rotatably mounted with the pressure ring handle and the second synchronous gear. The L-shaped pressure plate has a meshing hole that meshes with the second synchronous gear. The second drive shaft is used to drive the L-shaped pressure plate away from or closer to the L-shaped fixing plate. A space for inserting the binding ring is formed between the L-shaped pressure plate and the L-shaped fixing plate.

[0010] In this invention, rotating the pressure ring handle drives the second drive shaft to rotate, which in turn drives the second synchronous gear. The rotation of the second synchronous gear drives the L-shaped pressure plate meshing with it, bringing the L-shaped pressure plate closer to the L-shaped fixing plate. This presses the binding ring, placed between the L-shaped pressure plate and the L-shaped fixing plate, together, ensuring the binding ring engages with the holes in the paper without disengaging, thus completing the binding operation. After binding is complete, rotating the pressure ring handle in the opposite direction moves the L-shaped pressure plate away from the L-shaped fixing plate, facilitating the removal of the bound paper.

[0011] Furthermore, a drive gear is coaxially rotatably mounted on the output end of the drive motor; a rack is mounted on the tool assembly;

[0015] Furthermore, a second guide rail is provided on the L-shaped fixing plate, and a limit block is provided on the L-shaped pressure plate;

[0016] The pressure ring assembly also includes a positioning inclined plate, which is slidably connected to the second guide rail, and the inclined side of the positioning inclined plate is used to abut against the limiting block.

[0019] Furthermore, the binding machine also includes a margin adjustment assembly, which includes an adjustment rod, an adjustment plate, and an adjustment block. One end of the adjustment rod is fixedly connected to the adjustment block, and the other end extends out of the frame. The adjustment plate is disposed between the cutter assembly and the base plate of the frame. The adjustment plate is provided with a slanted guide rail, and the adjustment block is slidably connected to the slanted guide rail for abutting against the edge of the paper.

[0020] Furthermore, the binding machine also includes a positioning component, which includes a positioning block and a third guide rail both mounted on the frame. The positioning block is slidably connected to the third guide rail and is used to abut against the edge of the paper.

Detailed Implementation

[0031] This utility model provides a binding machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description of this utility model. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit this utility model.

[0032] Reference Figures 1-5 The present invention provides a binding machine, including a frame 100, wherein the binding machine further includes a drive motor 200 and a cutter assembly 300 disposed on the frame 100; the drive motor 200 is connected to the cutter assembly 300 in a transmission manner, and the drive motor 200 is used to drive the cutter assembly 300 to move up and down to punch holes in the paper.

[0033] The binding machine also includes a pressing ring assembly 400 disposed on the frame 100, which is used to press the binding ring.

[0034] In this invention, a drive motor 200 is mounted on the frame 100. The drive motor 200 is connected to the cutter assembly 300, which moves the cutter assembly 300 up and down. After paper is placed at the corresponding position, the cutter assembly 300 moves downward to punch holes in the paper. After punching, the cutter assembly 300 moves upward and withdraws from the punched holes, completing the punching operation. After punching, the binding ring is opened and inserted into the punched holes in the paper. Then, the binding ring is pressed and tightened by the provided pressure ring assembly 400, completing the binding operation.

[0035] Reference Figure 1 and Figure 2 In one specific embodiment of this utility model, a drive gear 210 is coaxially rotatably mounted on the output end of the drive motor 200; a rack 310 is mounted on the tool assembly 300.

[0036] The binding machine also includes a first drive shaft 320, a half gear 330, and a first synchronous gear 340. The first drive shaft 320 is rotatably mounted on the frame 100. The half gear 330 is coaxially rotatably mounted with the first drive shaft 320 and meshes with the drive gear 210. The first synchronous gear 340 is coaxially rotatably mounted with the first drive shaft 320 and meshes with the rack 310.

[0037] In this utility model, the drive motor 200 drives the drive gear 210 to rotate, the drive gear 210 meshes with the drive half gear 330, the first transmission shaft 320, which is coaxially rotated with the half gear 330, rotates, and the first synchronous gear 340, which is coaxially rotated with the first transmission shaft 320, rotates, driving the rack 310 meshing with it to move up and down, thereby enabling the tool assembly 300, which is fixedly connected to the rack 310, to move up and down to realize the drilling operation.

[0038] The number of first synchronous gears 340 can be set to two, and the two first synchronous gears 340 are respectively located at both ends of the first transmission shaft 320. The racks 310 provided on the tool assembly 300 can be set to two, corresponding to the first synchronous gears 340 at both ends of the first transmission shaft 320. When drilling, the tool assembly 300 applies force more evenly, which is conducive to ensuring drilling accuracy.

[0039] Specifically, after the tool assembly 300 moves down to a suitable stroke, the motor can reverse to drive the tool assembly 300 to move up, so that the tool head in the tool assembly 300 is pulled out of the hole.

[0040] Specifically, in this invention, a first guide rail can be provided on the frame 100, which is slidably connected to the rack 310 to further ensure smooth up-and-down movement of the tool assembly 300. Furthermore, switches (not shown in the figure) electrically connected to the drive motor 200 can be provided at suitable locations on the frame 100, such as at both ends of the first guide rail. These switches, through the interaction of the rack 310 or the top and bottom of the tool assembly 300 with the trigger terminals of the switches, control the drive motor 200 to stop or reverse after the tool assembly 300 moves down to a predetermined position, and control the drive motor 200 to stop after the tool assembly 300 moves up to a predetermined position. Specifically, the switches can be limit switches, magnetic switches, optocoupler switches, or proximity switches.

[0041] Reference Figures 1-3In one specific embodiment of this utility model, the pressure ring assembly 400 includes a second drive shaft 410, a pressure ring handle 420, a second synchronous gear 430, an L-shaped fixing plate 440, and an L-shaped pressure plate 450. The second drive shaft 410 is rotatably mounted on the frame 100. The second drive shaft 410 is coaxially rotatably mounted with the pressure ring handle 420 and the second synchronous gear 430. The L-shaped pressure plate 450 has a meshing hole 451 that meshes with the second synchronous gear 430. The second drive shaft 410 is used to drive the L-shaped pressure plate 450 away from or closer to the L-shaped fixing plate 440. A space for inserting the binding ring is formed between the L-shaped pressure plate 450 and the L-shaped fixing plate 440.

[0042] In this invention, rotating the pressure ring handle 420 drives the second transmission shaft 410 to rotate, and the second synchronous gear 430, which rotates with the second transmission shaft 410, drives the L-shaped pressure plate 450 meshing with it. This causes the L-shaped pressure plate 450 to move closer to the L-shaped fixing plate 440, pressing the binding ring placed between the L-shaped pressure plate 450 and the L-shaped fixing plate 440. This ensures the binding ring engages with the hole in the paper and does not come off, completing the binding operation. After binding, rotating the pressure ring handle 420 in the opposite direction moves the L-shaped pressure plate 450 away from the L-shaped fixing plate 440, facilitating the removal of the bound paper. The movement of the L-shaped pressure plate 450 closer to and further away from the L-shaped fixing plate 440 is achieved by providing a slider on the L-shaped pressure plate 450 and a corresponding guide rail structure on the frame 100, allowing for relative movement via sliding on the guide rails.

[0043] The pressure ring handle 420 can be detachably connected to the second drive shaft 410, and then installed on the second drive shaft 410 when manual pressure ring is required.

[0044] The number of second synchronous gears 430 can be set to two, and the two second synchronous gears 430 are respectively located at both ends of the second transmission shaft 410. The L-shaped pressure plate 450 can be provided with corresponding meshing holes 451 at both ends of the L-shaped pressure plate 450 according to the second synchronous gears 430. When pressing the ring, the force applied by the L-shaped pressure plate 450 is more uniform, which is conducive to ensuring the ring pressing effect.

[0045] Reference Figures 1-3 In one specific embodiment of this utility model, a second guide rail 441 is provided on the L-shaped fixing plate 440, and a limit block 452 is provided on the L-shaped pressure plate 450.

[0046] The pressure ring assembly 400 also includes a positioning inclined plate 460, which is slidably connected to the second guide rail 441, and the inclined side of the positioning inclined plate 460 is used to abut against the limiting block 452.

[0047] In this invention, a positioning inclined plate 460 is provided. The positioning inclined plate 460 abuts against a limiting block 452 provided on an L-shaped pressure plate 450 via its inclined edge. When the L-shaped pressure plate 450 is engaged by the pressure ring handle 420, the limiting block 452 will abut against the positioning inclined plate 460 when the L-shaped pressure plate 450 approaches the L-shaped fixing plate 440 to a certain extent, stopping the pressure ring operation and preventing excessive pressing that could deform or damage the binding ring. Simultaneously, by providing a slidable connection between the positioning inclined plate 460 and a second guide rail 441 provided on the L-shaped fixing plate 440, the position of the positioning inclined plate 460 can be controlled to allow different parts of its inclined edge to abut against the limiting block 452. This controls the different strokes of the L-shaped pressure plate 450 to accommodate binding rings of different sizes, preventing damage caused by insufficient or excessive pressing of the binding ring.

[0048] The positioning inclined plate 460 can be equipped with a slider to slide and connect with the second guide rail 441, ensuring that the positioning inclined plate 460 can slide along the extension direction of the second guide rail. The positioning inclined plate 460 can also be provided with a positioning hole, and a positioning knob that is threaded into the positioning hole can be provided to fix the position of the positioning inclined plate 460 after adjustment, so as to avoid the positioning inclined plate 460 from shifting during the pressing ring process and affecting the fastening effect of the binding ring.

[0049] Among them, while ensuring that the tool assembly 300 can make holes, the size of the positioning inclined plate 460 can be adjusted to ensure that the stroke control of the positioning inclined plate 460 on the limit block 452 does not affect the drilling effect that needs to be performed simultaneously.

[0050] Reference Figure 1 and Figure 2 In one specific embodiment of this utility model, a transmission gear 500 meshes between the first synchronous gear 340 and the second synchronous gear 430.

[0051] In this invention, a transmission gear 500 is arranged between the first synchronous gear 340 and the second synchronous gear 430. Simultaneously, the drive motor 200 drives the tool assembly 300 to complete its operation, and also synchronously drives the punching and pressing ring operation, improving binding efficiency. Furthermore, the tool assembly 300 can also be driven to complete the punching operation when passing the punching and pressing ring. Even in the event of a power outage, the binding operation can be completed manually, making it convenient to operate.

[0052] Specifically, the transmission gears 500 are rotatably mounted on the frame. When there are two of each of the first synchronous gear 340 and the second synchronous gear 430, the number of transmission gears 500 can be set accordingly to ensure smooth transmission.

[0053] Reference Figure 2In one specific embodiment of this utility model, a return spring 600 is sleeved on the first drive shaft 320. One end of the return spring 600 is fixedly connected to the first drive shaft 320, and the other end is fixedly connected to the frame 100.

[0054] Specifically, the return spring 600 can be configured such that when the tool assembly 300 moves downward, the return spring 600 is stretched, accumulating elastic potential energy. The return spring 600 releases the elastic potential energy, pulling the tool assembly 300 upward.

[0055] In this utility model, by setting a return spring 600 that is fixedly connected at both ends to the first drive shaft 320 and the frame 100 respectively, after being sleeved on the first drive shaft 320, when the first drive shaft 320 is rotated to drive the tool assembly 300 to move downward, the return spring 600 is stretched to accumulate elastic potential energy. After the drilling is completed, the return spring 600 resets and releases the elastic potential energy, helping to pull the tool assembly 300 upward so that the tool assembly 300 can be pulled out of the drilled hole and return to its initial position.

[0056] Specifically, in the embodiment of this invention that includes a transmission gear 500, the reset spring 600 can also drive the L-shaped pressure plate 450 to reset during resetting, eliminating the need for manual resetting of the pressure ring assembly 400 and improving binding efficiency. Furthermore, manual binding operation can be achieved even in the event of a power outage. After the operation, the reset spring 600 can reset the cutter assembly 300 and the L-shaped pressure plate 450, effectively ensuring the continuation of repeated binding operations.

[0057] Reference Figure 2 and Figure 5 In one specific embodiment of this utility model, the frame 100 is provided with a pull-out hole 110 and a drop hole 120. The pull-out hole 110 is located on one side of the frame 100, and the drop hole 120 corresponds to the tool assembly 300.

[0058] The binding machine also includes a collection box 130, one end of which is provided with a pull-out part 131, and the other end of the collection box 130 is movably connected to the frame 100 through the pull-out hole 110. The opening of the collection box 130 is connected to the drop hole 120.

[0059] In this invention, by providing a drop hole 120 corresponding to the cutter assembly 300, the cutter head in the cutter assembly 300 can better penetrate the paper, maintaining a good punching effect even when punching multiple sheets of paper simultaneously. After punching, a large amount of debris is generated, which is collected by a collection box 130 connected to the drop hole 120, keeping the punching operation clean. The collection box 130 is movably connected to the frame 100, and can be pulled out via the pull-out part 131 to promptly clean up accumulated debris.

[0060] Reference Figure 4 In one specific embodiment of this utility model, the binding machine further includes a margin adjustment assembly 700. The margin adjustment assembly 700 includes an adjustment rod 710, an adjustment plate 720, and an adjustment block 730. One end of the adjustment rod 710 is fixedly connected to the adjustment block 730, and the other end extends out of the frame 100. The adjustment plate 720 is disposed between the cutter assembly 300 and the base plate of the frame 100. An inclined guide rail 721 is provided on the adjustment plate 720. The adjustment block 730 is slidably connected to the inclined guide rail 721 and is used to abut against the edge of the paper.

[0061] In this invention, the edge adjustment component 700 allows for adjustment of the punching distance of the paper edge to meet practical usage needs. During adjustment, the adjusting rod 710 is fixedly connected to the adjusting block 730, and the adjusting block 730 is slidably connected to the inclined guide rail 721 on the adjusting plate 720. Thus, the adjusting rod 710 and the adjusting block 730 slide together along the inclined guide rail 721. After adjusting to a suitable distance, paper is placed and pressed against the edge of the adjusting block 730. Once positioned, punching is performed to meet the required punching distance. The adjusting plate 720 must have a corresponding through hole when crossing the drop hole 120 to allow the blade head of the blade assembly 300 to pass smoothly.

[0062] Reference Figure 5 In one specific embodiment of this utility model, the binding machine further includes a positioning component, which includes a positioning block 810 and a third guide rail 820 both disposed on the frame 100. The positioning block 810 is slidably connected to the third guide rail 820 and is used to abut against the edge of the paper.

[0063] In this utility model, by setting a positioning block 810 that abuts against the paper, the positioning block 810 can slide along the third guide rail 820. In conjunction with the adjusting block 730 that also abuts against the paper, the paper is conveniently positioned so that holes can be punched at the required positions. At the same time, when punching multiple sheets of paper, it can also keep them neat and ensure the punching accuracy.

[0064] Reference Figure 5 and Figure 6 In one specific embodiment of this utility model, the binding machine also includes a corner protector 900, which is disposed at the bottom edge of the frame 100;

[0065] The corner protector 900 is provided with a backing tooth 910, and the frame 100 is provided with a locking hole 140 that mates with the backing tooth 910.

[0066] In this invention, by providing corner protectors 900 at the bottom edge of the frame 100, the corners of the bottom of the frame 100 can be protected, and the stability of the binding machine can be improved. Especially when the ring pressing operation is required, it can prevent the binding machine from slipping and ensure the binding effect. Specifically, by providing undercut teeth 910 on the corner protectors 900 and providing locking holes on the frame 100 that cooperate with the undercut teeth 910, when the corner protectors 900 are installed on the frame 100, the undercut teeth 910 can be engaged with the locking holes 140 to lock the corner protectors 900, making them less likely to fall out and facilitating the installation and removal of the corner protectors 900.

[0067] In the specific implementation of the binding machine provided by this utility model, the working principle is as follows:

[0068] Connect the power supply, adjust the position of the positioning block 810 on the third guide rail 820, adjust the position of the adjusting rod 710, and adjust the edge distance adjustment component 700 to control the edge distance to be punched. Specifically, this is done by controlling the sliding position of the adjusting block 730 on the inclined guide rail 721 on the adjusting plate 720. Place the paper so that its edge abuts against the positioning block 810 and the adjusting block 730. At the same time, adjust the positioning inclined plate 460 to a suitable sliding position on the second guide rail 441 and fix it. Arrange the punched paper to be bound, insert the opened binding ring into the opening of the paper, and extend the binding ring into the space between the L-shaped pressure plate 450 and the L-shaped fixing plate 440.

[0069] When the power is turned on, the drive gear 210 at the output end of the drive motor 200 rotates, meshing with the half gear 330. The first transmission shaft 320, which meshes with the half gear 330, rotates, and the first synchronous gear 340 rotates simultaneously, meshing with and driving the rack 310 of the cutter assembly 300 to move, thereby driving the cutter assembly 300 to move downward and punch holes in the paper.

[0070] During the downward movement of the cutting tool assembly 300 to punch holes, the corner guards 900 located at the bottom edge of the frame 100 ensure that the binding machine does not slip. The return spring 600, sleeved on the first transmission shaft 320, is stretched to accumulate elastic potential energy. At the same time, the debris generated by the cutting head in the cutting tool assembly 300 cutting the paper enters the collection box 130 through the drop hole 120. Simultaneously, the first synchronous gear 340 drives the second synchronous gear 430 to rotate through the transmission gear 500. The second synchronous gear 430 drives the L-shaped pressure plate 450 to move towards the L-shaped fixing plate 440 through the meshing hole 451 on the L-shaped pressure plate 450, pressing and tightening the binding ring placed between the L-shaped pressure plate 450 and the L-shaped fixing plate 440, thus completing the binding.

[0071] After drilling is completed, the tool assembly 300 moves upward and returns to its initial position under the action of motor reversal or return spring 600 reset. At this time, the second drive shaft 410 and L-shaped pressure plate 450 are also returned to their initial positions. Then, the collection box 130 is pulled out from the pull hole 110 through the pull part 131 to clean up the debris.

[0072] When manually driven by the pressure ring handle 420, the second drive shaft 410 is rotated by engaging the pressure ring handle 420, causing the L-shaped pressure plate 450 with the meshing hole 451 to move towards the L-shaped fixing plate 440, pressing the pressure ring placed between them. Simultaneously, the second synchronous gear 430, which rotates coaxially with the second drive shaft 410, drives the first synchronous gear 340 to rotate via the drive gear 500. The first drive shaft 320, which rotates coaxially with the first synchronous gear 340, rotates, stretching the return spring 600 to accumulate elastic potential energy. At this time, the tool assembly 300 moves down, and drilling can also be performed. After the pressure ring operation is completed, the pressure ring handle 420 is released. Similarly, the return spring 600 resets the second drive shaft 410, the L-shaped pressure plate 450, and the tool assembly 300, completing the drilling and binding.

[0073] With the design of this utility model, the binding machine can perform punching and ring pressing operations simultaneously, improving binding efficiency. Furthermore, by setting the transmission gear 500 and the return spring 600, the machine can be reset after punching or pressing, which also helps to improve binding efficiency.

[0074] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of this utility model.
