Description

Technical Field

[0001] This invention relates to the field of printing consumables technology, and more particularly to a punching and binding machine. Background Technology

[0002] A hole punching and binding machine is a modern office equipment that integrates punching and binding functions, designed specifically for office environments where document organization and binding are frequent. A hole punching and binding machine generally includes a punching mechanism and a binding mechanism. Currently, the market typically offers punching mechanisms with a fixed number of holes and clamping ring mechanisms with a fixed iron ring diameter, which are insufficient to meet diverse and personalized usage needs.

[0003] Regarding punching mechanisms, existing equipment is mostly designed for A4 paper size and has a fixed number of holes, making it impossible to flexibly adjust the number of holes according to actual needs, thus limiting its applicability. Furthermore, during the punching process, the punches typically fall in a uniform order, lacking optimized control over the punching sequence. This results in significant resistance when penetrating multiple sheets of paper, often requiring users to apply additional force to complete the operation, affecting ease of use and operational comfort. As for the clamping ring mechanism, the metal rings sold on the market come in various specifications and diameters, each requiring different clamping ring strokes and limit positions during the clamping process. Additionally, due to differences in manufacturing processes and material selection among manufacturers, even metal rings with the same nominal diameter may have slight deviations in actual size. Existing clamping ring mechanisms generally lack the ability to precisely adjust the clamping ring stroke, making it difficult to adapt to the binding needs of different sized metal rings, leading to insufficient or excessive clamping, affecting binding quality and document aesthetics.

[0004] To address these issues, this invention provides a punching and binding machine that effectively solves the aforementioned problems. It features a simple structure, convenient operation, controllable punching quantity, adjustable pressure ring limit, and effective optimization of the punching sequence. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a punching and binding machine with a simple structure, convenient operation, controllable punching quantity, adjustable pressure ring spacing, and effective optimization of punching sequence.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A punching and binding machine, comprising:

[0008] Base;

[0009] A bracket, which is fixed to the base;

[0010] A drive mechanism, which is connected to the bracket;

[0011] A drilling mechanism includes a limiting plate, a drilling blade, and an adjusting pin. The limiting plate is slidably connected to the driving mechanism, and the adjusting pin is connected to the top end of the drilling blade. The limiting plate is provided with a limiting groove that allows the adjusting pin to slide into the groove. The driving mechanism drives the limiting plate to move, and the adjusting pin moves between an abutting state and a sliding state. In the abutting state, the adjusting pin abuts against the limiting point of the limiting groove, and the limiting plate drives the drilling blade to move synchronously. In the sliding state, the limiting groove allows the adjusting pin to move within it.

[0012] A pressure ring mechanism is slidably connected to the bracket, and the driving mechanism drives the pressure ring mechanism to move between a pressure ring position and a release position.

[0013] The beneficial effects of this invention are as follows: With the above-described structure, both the punching mechanism and the ring-pressing mechanism are mounted on the same base via a bracket. The drive mechanism simultaneously drives both the punching mechanism and the ring-pressing mechanism to perform punching and ring-pressing operations respectively. An adjusting pin is connected to the top of the punching blade, allowing the punching blade to move synchronously with the adjusting pin. The drive mechanism drives the limiting plate to move between the punching position and the release position. In the contact state, the punching blade's punching operation is controlled by the contact between the adjusting pin and the limiting point on the limiting groove. When the adjusting pin contacts the limiting point of the limiting groove, the power of the drive mechanism is transmitted to the punching blade via the limiting plate, thereby driving it to perform the punching operation. At this time, the limiting plate moves to the punching position. In the sliding state, the adjusting pin is freely inserted into the limiting groove (i.e., uncontrolled and freely moving), and the punching blade cannot receive the driving force from the drive mechanism, so it will not perform the punching action. At this time, the limiting plate moves to the release position. The drilling function of the punch is started and stopped by adjusting the contact between the adjusting pin and the upper limit point of the limiting groove or by adjusting the free movement of the adjusting pin. At the same time, the drive mechanism also drives the pressure ring mechanism to move between the pressure ring position and the release position. Attached Figure Description

Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] Reference Figures 1 to 17 A punching and binding machine, comprising:

[0042] Base 100;

[0043] A bracket 200 is fixed to the base 100;

[0044] A drive mechanism 300 is connected to the bracket 200;

[0045] A drilling mechanism 400 includes a limiting plate 410, a drilling blade 420, and an adjusting pin 430. The limiting plate 410 is slidably connected to the driving mechanism 300, and the adjusting pin 430 is connected to the top end of the drilling blade 420. The limiting plate 410 is provided with a limiting groove 411 that allows the adjusting pin 430 to slide. The driving mechanism 300 drives the limiting plate 410 to move, and the adjusting pin 430 moves between an abutting state and a sliding state. In the abutting state, the adjusting pin 430 abuts against the limiting point of the limiting groove 411, and the limiting plate 410 drives the drilling blade 420 to move synchronously. In the sliding state, the limiting groove 411 allows the adjusting pin 430 to move within it.

[0046] A pressure ring mechanism 500 is slidably connected to the bracket 200, and the driving mechanism 300 drives the pressure ring mechanism 500 to move between the pressure ring position and the release position.

[0047] With the above-described structure, both the drilling mechanism 400 and the ring-pressing mechanism 500 are mounted on the same base 100 via the bracket 200. The drive mechanism 300 simultaneously drives the drilling mechanism 400 and the ring-pressing mechanism 500 to perform drilling and ring-pressing operations respectively. The adjusting pin 430 is connected to the top of the drilling blade 420, allowing the drilling blade 420 to move synchronously with the adjusting pin 430. The drive mechanism 300 drives the limiting plate 410 to move between the drilling position and the release position. In the abutting state, the drilling blade 420 is controlled to perform a drilling operation by the abutting engagement between the adjusting pin 430 and the limiting point on the limiting groove 411. When the adjusting pin 430 abuts against the limiting point of the limiting groove 411, the power of the drive mechanism 300 is transmitted to the punching knife 420 via the limiting plate 410, thereby driving it to perform a punching operation. At this time, the limiting plate 410 moves to the punching position. In the sliding state, the adjusting pin 430 is freely inserted in the limiting groove 411 (i.e., uncontrolled and free to move). The punching knife 420 cannot receive the driving force from the drive mechanism 300, and the punching knife 420 will not perform a punching action. At this time, the limiting plate 410 moves to the release position. The punching function of the punching knife 420 is started and stopped by the abutment of the adjusting pin 430 against the upper limit point of the limiting groove 411 or by the free movement of the adjusting pin 430. At the same time, the drive mechanism 300 also drives the pressure ring mechanism 500 to move between the pressure ring position and the release position. Preferably, there are twelve punching blades 420 and twelve adjusting pins 430, and the punching blades 420 and adjusting pins 430 are in a one-to-one correspondence. Each adjusting pin 430 independently controls its corresponding punching blade 420, thereby achieving multi-point synchronous punching.

[0048] In this embodiment, the drilling mechanism 400 further includes a limiting block 431 protruding from the surface of the adjusting pin 430. In the abutting state, the limiting block 431 abuts against the limiting point, and the limiting plate 410 drives the drilling blade 420 to move downwards synchronously. In the sliding state, the limiting groove 411 allows the adjusting pin 430 to move within it. Through the above structure, at least a portion of the adjusting pin 430 (the portion without the limiting block 431) is always inserted into the limiting groove 411 and can move freely within it, thereby achieving a linkage connection between the limiting plate 410 and the drilling blade 420. Figures 11-13 As shown, the limiting block 431 protrudes from the outer peripheral surface of the adjusting pin 430. When it abuts against the limiting point on the limiting groove 411, it can transmit the power of the limiting plate 410 to the adjusting pin 430. Through the connection between the adjusting pin 430 and the punching knife 420, the punching action of the punching knife 420 is triggered. Figure 12 and 13 The diagram shows that when the adjusting pin 430 is pulled outward (i.e., the limiting block 431 cannot abut against the limiting point on the limiting groove 411), all or part of the punching tool 420 is pressed down to participate in the punching operation; for example Figure 11 As shown, when the limiting block 431 does not abut against the limiting point on the limiting groove 411, the adjusting pin 430 can move freely up and down within the limiting groove 411 (with the limiting plate 410 as the reference point). (If the driving mechanism 300 controls the up and down movement of the limiting plate 410, then with the adjusting pin 430 as the reference point, the limiting plate 410 is moving up and down). The adjusting pin 430 and the punch 420 connected to it cannot receive the drive from the driving mechanism 300, and therefore cannot trigger the punching function of the punch 420. Through the mechanical cooperation between the limiting block 431 and the limiting groove 411, the reliable triggering of the punching action of the punch 420 is achieved, which can meet the user's personalized needs for the number of holes punched.

[0049] In this embodiment, the limiting groove 411 includes a first groove 4111 and a second groove 4112 communicating with the first groove 4111, and the limiting point is located at the connection between the first groove 4111 and the second groove 4112. Through the above structural arrangement, as... Figure 10As shown, the position of the connection between the first groove 4111 and the second groove 4112, near the upper inner wall of the second groove 4112, is defined as the limiting point. The first groove 4111 provides a guide and sliding path for the adjusting pin 430, ensuring its smooth movement and accurate positioning. The upper inner wall of the second groove 4112 can abut against the limiting block 431, forming a trigger mechanism for the punching knife 420 to perform the punching action. When the limiting block 431 abuts against the limiting point, the punching driving force is transmitted from the limiting plate 410 through the limiting block 431 to the adjusting pin 430, thereby driving the punching knife 420 to press down and complete the punching. In the released position, part of the adjusting pin 430 (the part without the limiting block 431) can move freely up and down in the first groove 4111 and the second groove 4112, the limiting block 431 disengages from the effective abutment position of the limiting point, the transmission of the punching driving force is interrupted, and the punching action of the punching knife 420 cannot be performed. This structure achieves controllable triggering of the drilling mechanism 400 by designing the limiting groove 411 as a first groove 4111 with a guiding function and a second groove 4112 with a triggering function for drilling. At this time, the first groove 4111 and the second groove 4112 are used to allow the insertion and movement of the adjusting pin 430 (the part without the limiting block 431), mainly serving a guiding and accommodating function; the upper inner sidewall of the second groove 4112 is used to abut against the limiting block 431, mainly serving to transmit the drilling driving force to trigger the drilling action of the drilling knife 420. Preferably, the width of the first groove 4111 is smaller than the width of the second groove 4112; the width of the limiting block 431 is smaller than the width of the second groove 4112, and the width of the limiting block 431 is larger than the width of the first groove 4111. This arrangement allows the limiting block 431 to abut against the upper inner wall of the second groove 4112, while preventing it from being movably inserted into the first groove 4111; the width of the adjusting pin 430 is smaller than the width of the first groove 4111, allowing part of the adjusting pin 430 to be movably inserted into the first groove 4111 and the second groove 4112. Preferably, Figure 11 As shown, when the adjusting pin 430 is pulled outward, it is in a sliding state. The limiting block 431 and the limiting groove 411 have no corresponding relationship. Under the drive of the driving mechanism 300, the limiting block 431 will not abut against the second groove 4112. Part of the adjusting pin 430 (the part without the limiting block 431) can be movably inserted into the first groove 4111 and the second groove 4112, so the punch 420 cannot perform the punching operation. Figure 11 , 12 As shown, the adjusting pin 430 is in the abutting state. The adjusting pin 430 is pressed inward and pushed. The limiting block 431 and the limiting groove 411 have a corresponding relationship, so that the limiting block 431 and the second groove 4112 abut against each other.

[0050] In this embodiment, the vertical distance from the bottom to the opening of each of the second grooves 4112 is not exactly the same. Through the above structural arrangement, as... Figure 10As shown, the vertical distance from the bottom to the opening of the second groove 4112 is defined as h, and the h value is not exactly the same. Different h values ​​of the second groove 4112 correspond to different punching trigger sequences or punching strokes. When the limiting plate 410 moves with the drive mechanism 300, the limiting blocks 431 on each adjusting pin 430 sequentially abut against the upper inner wall within the second groove 4112 at different heights, i.e., different h values. The second groove 4112 with a smaller h value will cause the limiting block 431 to reach the abutment position earlier, thereby controlling the start of the corresponding punching knife 420 earlier. Therefore, by designing second grooves 4112 with different h values, time-sharing punching and staggered punching of multiple punching knives 420 can be achieved, effectively avoiding the resistance caused by the paper during the punching operation.

[0051] In this embodiment, the driving mechanism 300 includes a handle 310, a drive shaft 320, and a driving component 330. The drive shaft 320 is rotatably connected to the bracket 200. The handle 310 is rotatably sleeved on both sides of the drive shaft 320. The driving component 330 is arranged adjacent to the handle 310 and is connected to the limiting plate 410. The handle 310 drives the drive shaft 320 and the driving component 330 to rotate synchronously, so that the limiting plate 410 moves up and down. With the above structure, when the user presses down on the handle 310, the driving force drives the driving component 330 to rotate synchronously through the drive shaft 320, thereby driving the limiting plate 410 to move along a predetermined trajectory. When the limiting plate 410 moves to the preset position, the second groove 4112 abuts against the limiting block 431, thereby driving the punch 420 to press down and complete the punching operation.

[0052] In this embodiment, the driving component 330 includes a snap-fit ​​portion 331 and an engagement portion 332. The limiting plate 410 is provided with a snap-fit ​​hole 413 that allows the snap-fit ​​portion 331 to snap into place. The snap-fit ​​portion 331 and the engagement portion 332 are located on both sides of the driving shaft 320. With the above-described structure, the engagement portion 332 is positioned away from the upper end of the handle 310, while the snap-fit ​​portion 331 is positioned close to the upper end of the handle 310. This arrangement allows the handle 310 to simultaneously achieve two motion behaviors when pressed down: the snap-fit ​​portion 331 drives the limiting plate 410 to move downwards synchronously, and the engagement portion 332 rotates.

[0053] In this embodiment, the bracket 200 is provided with a first guide rail 210, and a plug-in portion 412 protrudes from the end of the limiting plate 410. The plug-in portion 412 is slidably inserted into the first guide rail 210 and moves up and down along the first guide rail 210. Through the above structure, the first guide rail 210 and the plug-in portion 412 constitute a guiding and mating mechanism, precisely guiding the up and down movement trajectory of the limiting plate 410, ensuring that the limiting plate 410 runs stably along a predetermined straight path under the drive of the driving mechanism 300. The guiding structure improves the repeatability and reliability of the drilling action, ensuring the consistency of the synchronous action of the limiting plate 410 and each drilling blade 420.

[0054] In this embodiment, the punching mechanism 400 further includes a punching frame 440 connected to the base 100. The upper end of the punching frame 440 is provided with a second through hole 441. The driving mechanism 300 drives the punching blade 420 to move up and down along the second through hole 441. Through the above structural arrangement, the punching frame 440 is a device for placing punched paper and a key structure for realizing the punching operation. The second through hole 441 guides and positions the punching action of the punching blade 420. The driving mechanism 300 drives the punching blade 420 to press down into the second through hole 441, thereby ensuring the accuracy of the punching position and the consistency of the shape of the second through hole 441. Simultaneously, the fixed connection between the punching frame 440 and the base 100 ensures the rigidity and stability of the overall structure, further improving the punching accuracy and the reliability of equipment operation.

[0055] In this embodiment, the punching mechanism 400 further includes a guide frame 450. The lower end of the guide frame 450 has a first through hole 451. The punching blade 420 passes through the first through hole 451 and corresponds one-to-one with the second through hole 441. Through this structure, the guide frame 450 and the first through hole 451 guide the punching operation of the punching blade 420, effectively enhancing the straightness and stability of the punching blade 420 during reciprocating motion. The first through hole 451 forms a linear constraint on the punching blade 420, preventing it from bending, swaying, or jamming during frequent movements, thereby further improving punching accuracy and the service life of the punching blade 420. Simultaneously, the blade tip of the punching blade 420 passes through the first through hole 451 and protrudes from the bottom surface of the guide frame 450, ensuring that the punching blade 420 can smoothly enter the second through hole 441 and effectively punch the paper, guaranteeing the reliable completion of the punching action.

[0056] In this embodiment, the punching mechanism 400 further includes a return torsion spring 460, one end of which is connected to the guide frame 450 and the other end to the drive shaft 320. With this structure, after the punching operation is completed, the user releases the handle 310, and the potential energy stored in the return torsion spring 460 due to the elastic torsion during the punching process is released, generating a restoring torque. This drives the drive shaft 320 to rotate in the opposite direction, thereby causing the limit plate 410, adjusting pin 430, and punching blade 420 to retract upwards, returning to their initial standby position. Simultaneously, this restoring force also causes the guide frame 450 to separate from the punched paper, releasing the pressure and facilitating the removal of the punched paper and the next punching operation.

[0057] In this embodiment, the driving mechanism 300 further includes a transmission shaft 340 and a transmission gear 350. The transmission shaft 340 is rotatably connected to the bracket 200, and the transmission gear 350 is sleeved on the transmission shaft 340 and connected to the pressure ring mechanism 500. The transmission gear 350 meshes with the meshing part 332. The handle 310 drives the meshing part 332 to rotate, causing the transmission gear 350 to rotate synchronously, thereby moving the pressure ring mechanism 500 up and down. With the above structural configuration, as... Figure 8 The diagram illustrates the operational states of each component of the drive mechanism 300. When the user presses down on the handle 310, the driving force drives the drive component 330 to rotate via the drive shaft 320. The meshing part 332 drives the transmission gear 350 to rotate synchronously through gear engagement, which in turn drives the transmission shaft 340 to rotate, causing the connected pressing ring mechanism 500 to perform the pressing ring operation. The drive mechanism 300 distributes the power of the handle 310 to the pressing ring mechanism 500 through gear transmission, realizing the transmission path of "handle 310 - drive shaft 320 - meshing part 332 - transmission gear 350 - transmission shaft 340 - pressing ring mechanism 500".

[0058] In this embodiment, the driving mechanism 300 further includes a transmission plate 360. The transmission plate 360 ​​has a gear groove 361 that meshes with the transmission gear 350. The transmission plate 360 ​​is slidably connected to the bracket 200 and fixedly connected to the pressing ring mechanism 500. When the transmission gear 350 rotates, it drives the transmission plate 360 ​​to move up and down, thereby driving the pressing ring mechanism 500 to move up and down. With the above structure, the transmission gear 350 is connected to the pressing ring mechanism 500 through the transmission plate 360. When the transmission gear 350 rotates under the drive of the meshing part 332, its teeth mesh with the gear groove 361 on the transmission plate 360, converting the rotational motion into the linear motion of the transmission plate 360, thereby driving the transmission plate 360 ​​to move downward along the bracket 200, and then driving the pressing ring mechanism 500 to press down synchronously to complete the pressing ring operation. The transmission plate 360 ​​and the transmission gear 350 form a "gear-rack transmission mechanism," which realizes a reliable conversion from rotary motion to linear motion and can efficiently transmit the power of the drive mechanism 300 to the pressing ring operation of the pressing ring mechanism 500. At the same time, the sliding connection between the transmission plate 360 ​​and the bracket 200 provides good guidance and support, ensuring the reliability of the pressing ring operation.

[0059] In this embodiment, the bracket 200 is provided with a second guide rail 220, and a transmission part 362 protrudes from the end of the transmission plate 360. The transmission part 362 is slidably inserted into the second guide rail 220 and moves up and down along the second guide rail 220. Through the above structural arrangement, as... Figure 15 , 16 As shown, driven by the handle 310, the drive mechanism 300 engages with the gear groove 361 on the transmission plate 360 ​​via the transmission gear 350, causing the transmission plate 360 ​​to move downwards, so that the transmission part 362 slides linearly back and forth within the second guide rail 220. The second guide rail 220 and the transmission part 362 form a guiding engagement mechanism, which guides and constrains the linear movement of the transmission plate 360, effectively preventing it from deflecting during its vertical linear sliding movement, and ensuring that the transmission part 362 slides smoothly along the predetermined linear path of the second guide rail 220.

[0060] In this embodiment, the ring-pressing mechanism 500 includes a connecting plate 510 and a ring-pressing plate 520 slidably connected to the connecting plate 510. The upper end of the transmission plate 360 ​​is fixedly connected to the connecting plate 510. The transmission plate 360 ​​drives the connecting plate 510 to move up and down, thereby driving the ring-pressing plate 520 to move up and down. Through the above structural arrangement, the connecting plate 510 and the ring-pressing plate 520 are slidably connected, and the transmission plate 360 ​​is fixedly connected to the upper part of the connecting plate 510. In the ring-pressing position, when the transmission plate 360 ​​moves downward under the action of the driving mechanism 300, it drives the connecting plate 510 to move downward synchronously, and drives the ring-pressing plate 520 to move downward along a predetermined path, thereby performing a ring-pressing operation on the perforated paper with the iron ring, realizing the operation process of "transmission plate 360 ​​- connecting plate 510 - ring-pressing plate 520 - ring-pressing operation". In the release position, the handle 310 is released, and the transmission plate 360, connecting plate 510, and ring-pressing plate 520 move upward. Preferably, as... Figure 7 As shown, the connecting plate 510 and the pressure ring plate 520 can be slidably connected through the insertion and sliding fit of two hollow pillars, which can ensure a stable connection and power transmission between the connecting plate 510 and the pressure ring plate 520. Preferably, the pressing surface of the pressure ring plate 520 is covered with a fleece cloth. The fleece cloth acts as a buffer and protective layer, and can contact the surface of the iron ring during the pressing process, effectively preventing scratches, wear, or damage to the metallic luster of the outer surface of the iron ring during pressing.

[0061] In this embodiment, the pressing ring mechanism 500 further includes a base plate 530 for placing the iron ring. The base plate 530 is connected to the base 100. When the pressing ring plate 520 moves down close to the base plate 530, the pressing ring plate 520 applies pressure to the iron ring. Through the above structural arrangement, as... Figure 15 As shown, the base plate 530 is used to place and position the iron ring to be pressed. When the pressing plate 520 moves downward under the drive of the drive mechanism 300, the pressing surface of the pressing plate 520 gradually approaches and presses against the iron ring placed on the base plate 530, causing it to undergo plastic deformation and close the open iron ring, thus completing the pressing operation. Preferably, the base plate 530 is fixed inside the base 100 and is consistent with the plane of the base 100, and corresponds to the position of the pressing plate 520 in the vertical direction to ensure accurate correspondence of the vertical forces during the pressing process; and the base plate 530 is a magnetic plate, which can magnetically attract and fix the iron ring to be pressed, stably placing the open iron ring on the base plate 530, preventing it from shifting, rotating or misaligning before or during the pressing operation.

[0062] In this embodiment, the pressing ring mechanism 500 further includes an adjusting member 540, which is connected to both the pressing ring plate 520 and the connecting plate 510. The adjusting member 540 adjusts the distance between the connecting plate 510 and the pressing ring plate 520. Through this structure, the adjusting member 540 adjusts the distance between the pressing ring plate 520 and the base plate 530. Preferably, the adjusting member 540 is a threaded connection structure, such as an adjusting screw or lead screw assembly, with one end connected to the connecting plate 510 and the other end connected to the pressing ring plate 520. Rotating the adjusting member 540 drives the pressing ring plate 520 to move up and down, thereby precisely setting the initial distance between the pressing ring plate 520 and the base plate 530. Flexible adjustment of the distance between the pressing ring plate 520 and the base plate 530 controls the limiting position and compression amount of the pressing ring action, meeting the pressing ring requirements of iron rings of different diameters and specifications.

[0063] In this embodiment, the punching mechanism 400 further includes a scrap box 470, which is disposed below the punching frame 440, and the receiving space of the scrap box 470 is connected to the second through hole 441. With the above structure, during the punching process, the cut scraps are dislodged from the second through hole 441 and fall into the scrap box 470 under the drive of the output end of the punching mechanism 400. The scrap box 470 is used to collect the scraps generated during the punching operation, effectively preventing debris from scattering inside the punching and binding machine or on the base 100 surface, maintaining a clean punching environment, and avoiding malfunctions of the punching mechanism 400 caused by scrap accumulation. At the same time, the detachable design of the scrap box 470 facilitates regular cleaning and maintenance by the user.

[0064] In this embodiment, a housing 600 is also included. The bracket 200 is disposed inside the housing 600. The housing 600 has a scale line on the side near the pressing ring mechanism 500 to indicate the diameter of the iron ring. The housing 600 has a fixing pin 610 and a first fixing hole 620 on the side near the handle 310. The fixing pin 610 passes through the first fixing hole 620 and is detachably connected to the bracket 200. The handle 310 has a second fixing hole 311 corresponding to the first fixing hole 620. With the above structure, the bracket 200 is installed inside the housing 600, and the housing 600 provides protection, support, and aesthetic enhancement for the internal structure. The scale line on the side of the housing 600 near the pressing ring mechanism 500 corresponds to the position of the iron ring to be pressed, visually displaying the diameter of the iron ring. This allows the user to adjust the adjusting member 540 according to the iron ring size, moving the distance between the pressing ring plate 520 and the base plate 530. Figure 17As shown, the outer casing 600 has a fixing pin 610 and a first fixing hole 620 on the side near the handle 310. The handle 310 has a second fixing hole 311 that cooperates with the fixing pin 610. Preferably, one end of the fixing pin 610 is detachably fixed to the bracket 200 through the first fixing hole 620. When the punching and binding machine is in standby mode, the handle 310 can be rotated downward to the storage position, the first fixing hole 620 and the second fixing hole 311 can be aligned, and the fixing pin 610 can be fixed by passing through the first fixing hole 620 and the second fixing hole 311, thereby realizing the storage and locking of the handle 310.

[0065] In this embodiment, a positioning block 480 is provided on one side of the punching mechanism 400, and a positioning hole 110 corresponding to the positioning block 480 is provided on the base 100. The positioning block 480 is movably inserted into the positioning hole 110. Through the above structure, the positioning block 480 is detachably inserted into the positioning hole 110 to achieve precise positioning of the punching mechanism 400 during punching operations. The positioning block 480 and the positioning hole 110 form a positioning mating structure, used to position the paper to be punched, ensuring that it maintains an accurate spatial relative relationship with the punching blade 420 and the second through hole 441 during the punching process. In use, when the user needs to punch holes in A3 paper, after punching a portion of the A3 paper, the remaining portion needs to be bound. The completed holes are aligned with the positioning hole 110, and the positioning block 480 passes through the holes and the positioning hole 110 in sequence before punching the remaining portion. This structure ensures the consistency of the punching position for large-format paper.

[0066] In this embodiment, a positioning plate 120 is provided on the surface of the base 100 near the punching mechanism 400; an anti-slip component 130 is provided at the bottom of the base 100. Through the above structural arrangement, the positioning plate 120 is used to limit the perforated paper laterally or longitudinally. In standby mode, the positioning plate 120 can rotate and retract towards the edge of the base 100. The bottom of the base 100 is provided with the anti-slip component 130, which is preferably a rubber pad or anti-slip foot pad, increasing the friction between the base 100 and the worktable surface, effectively preventing slippage during punching or ring pressing operations. The positioning plate 120 and the punching mechanism 400 work together to ensure that the position of the perforated paper is consistent each time, improving the relative accuracy of the punched hole position and the edge of the paper, which is beneficial for subsequent assembly and matching with the iron ring. Preferably, as shown... Figure 14 As shown, one side of the base 100 is provided with a positioning area or groove structure for an open iron ring (iron ring to be pressed). During operation, one end of the open iron ring can be placed in this position, and the other end is used to receive the punched paper that has been punched, so that the punched paper can be accurately put into the iron ring, completing the pre-assembly of the paper ring and the iron ring, which provides convenience for the subsequent pressing ring operation.
