Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Binding machines play a vital role in many scenarios, such as daily office work and document organization. Traditional ring binding machines are mostly operated manually, requiring considerable force to complete the binding action, which is laborious and inefficient. Furthermore, the binding quality of manual binding machines is easily affected by uneven force applied by the operator, leading to inconsistent binding quality.

[0027] Therefore, this utility model proposes an electric ring-pressing binding machine, referring to... Figures 1 to 7 It includes a frame 100 and a tool assembly 200, a pressure ring assembly 300, a drive motor 400, and a transmission assembly 500, all mounted on the frame 100. The frame 100 has a first guide rail 110 and a second guide rail 120. The tool assembly 200 is movably mounted on the frame 100 and is slidably connected to the first guide rail 110. The tool assembly 200 has a first rack 210. The pressure ring assembly 300 is movably mounted on the frame 100 and is slidably connected to the second guide rail 110. The tool assembly 200 has a first rack 210. The pressure ring assembly 300 is movably mounted on the frame 100 and is slidably connected to the second guide rail 110. 20. A sliding connection is provided. The pressure ring assembly 300 is provided with a third rack 310. The drive motor 400 is used to drive the tool assembly 200 to slide along the first guide rail 110. The drive motor 400 is used to drive the pressure ring assembly 300 to slide along the second guide rail 120. A drive gear 410 is coaxially rotatably provided on the output end of the drive motor 400. The drive gear 410 is connected to the first rack 210 through the transmission assembly 500. The drive gear 410 is connected to the third rack 310 through the transmission assembly 500.

[0028] Under the action of the drive motor 400 and the transmission component 500, the cutter assembly 200 slides along the first guide rail 110 to punch holes in paper and other materials. The clamping ring assembly 300 slides along the second guide rail 120 in cooperation with the drive motor 400 and the transmission component 500 to complete the clamping ring binding action and ensure secure binding. The transmission component 500 connects the drive gear 410 of the drive motor 400 with the first rack 210 of the cutter assembly 200 and the third rack 310 of the clamping ring assembly 300, effectively transmitting the power of the drive motor 400 to the cutter assembly 200 and the clamping ring assembly 300, ensuring that the two can work in a coordinated and linked manner. Through the effective connection of the transmission component 500, the cutter assembly 200 and the clamping ring assembly 300 achieve linkage and orderly complete various binding-related operations of the binding machine, replacing the traditional manual binding machine binding method that requires a large amount of manual force, is laborious to operate, and is difficult to control precisely.

[0029] When using this electric ring-pressing binding machine, first arrange the documents to be bound and place them in the punching station of the binding machine. Start the electric ring-pressing binding machine, and the drive motor 400 starts working. The drive gear 410 at its output end rotates, and the drive gear 410 transmits power to the first rack 210 of the cutter assembly 200 through the transmission component 500, causing the cutter assembly 200 to slide up and down along the first guide rail 110 to complete the action of punching holes in the paper. The drive motor 400 reverses, and the cutter assembly 200 returns to the initial position, removing the punched paper. Install the binding ring on the paper and place it in the ring-pressing station of the binding machine. The drive gear 410 transmits power to the third rack 310 of the ring-pressing assembly 300 through the transmission component 500, causing the ring-pressing assembly 300 to slide up and down along the second guide rail 120, fastening the binding ring to the punched paper, completing the ring-pressing operation. The drive motor 400 reverses, and the ring-pressing assembly 300 returns to the initial position, ending the entire binding process.

[0030] Traditional transmission methods may suffer from problems such as complex structure, low transmission efficiency, and insufficient precision in the coordination between components, resulting in poor coordination between the cutting tool and the pressure ring during operation, affecting the efficiency and quality of binding. Therefore, in one embodiment, the transmission assembly 500 includes a first transmission shaft 510, a half gear 520, a second transmission shaft 530, a third gear 540, two second racks 550, two first gears 560, and two second gears 570. The first transmission shaft 510 is mounted on the frame 100 and is rotatable relative to the frame 100. The first gears 560 are coaxially rotatably mounted at both ends of the first transmission shaft 510. The half gears 520 are coaxially rotatably mounted on the first transmission shaft 510. Two first racks 210 are provided, with each first gear 560 meshing with a corresponding first rack 210. The half gears 520... The second gear 570 is coaxially rotatably disposed at both ends of the second drive shaft 530. The second rack 550 is disposed at both ends of the pressure ring assembly 300. The second gear 570 meshes with the second rack 550 in a one-to-one correspondence. The third gear 540 is disposed on the frame 100 and can rotate relative to the frame 100. The third gear 540 meshes with the third rack 310 and with one of the first gears 560. When the drive gear 410 drives the half gear 520 to rotate, it drives the first gear 560, which is coaxial with it, to rotate. The first gear 560 meshes with the first racks 210 located at both ends of the cutter assembly 200, so that the driving force on the cutter assembly 200 is balanced at both ends, thus moving strictly according to the predetermined linear trajectory to achieve precise perforation of the paper. At the same time, the first gear 560 meshes with the third gear 540 during rotation, and the third gear 540 meshes with the third gear on the pressure ring assembly 300. The racks 310 mesh with each other, and the power is transmitted to the pressure ring assembly 300 through the first gear 560, the third gear 540, etc., so that the pressure ring assembly 300 moves downward along the second guide rail 120 to perform the pressure ring operation on the paper. The second racks 550 set at both ends of the pressure ring assembly 300 mesh with the second gears 570 set at both ends of the second drive shaft 530, so that the driving force on the pressure ring assembly 300 is balanced at both ends, thus moving strictly according to the predetermined linear trajectory and achieving precise pressure ring operation.

[0031] If the fit between the upper and lower dies is not precise enough during the pressing process, problems such as loose pressing rings and uneven paper binding may occur. Therefore, in one embodiment, the pressing ring assembly 300 includes an upper pressing ring die 320 and a lower pressing ring die 330. The upper pressing ring die 320 is slidably connected to the first guide rail 110. The upper pressing ring die 320 and the lower pressing ring die 330 are arranged opposite to each other. The upper pressing ring die 320 is fixedly connected to the second rack 550 and the third rack 310. The lower pressing ring die 330 is fixedly mounted on the frame 100. The upper die 320 of the pressing ring is slidably connected to the first guide rail 110 and fixedly connected to the second rack 550 and the third rack 310. It can move precisely along the guide rail under the drive of the transmission component 500 and cooperate with the lower die 330 of the pressing ring fixed on the frame 100 to achieve accurate installation and positioning of the pressing ring. The lower die 330 of the pressing ring is fixedly installed on the frame 100 to ensure that pressure can be applied stably during the pressing ring process, so that the pressing ring is firmly fixed on the material and avoids the pressing ring from becoming loose or not being securely attached.

[0032] The upper die 320 and lower die 330 of the pressing ring move relative to each other during operation to complete the pressing ring operation. Operators may accidentally come into contact with the moving die, potentially causing injury. Therefore, in one embodiment, the pressing ring assembly 300 further includes a protective cover assembly 340. The protective cover assembly 340 includes a protective cover body 341 and a connector 342. The connector 342 is fixedly connected to the frame 100, and the protective cover is hinged to the connector 342, allowing the protective cover body 341 to rotate along the hinge axis to cover the upper die 320 and lower die 330. The rotatable protective cover body 341, rotating to cover the upper die 320 and lower die 330 during binding machine operation, effectively prevents operators from unknowingly coming into contact with the moving die, avoiding injuries such as pinching or impact caused by die movement, and providing reliable safety protection for operators.

[0033] A lack of fine-tuning in the ring-pressing process can easily lead to problems such as the ring being too tight and damaging the material, or the ring being too loose and causing the binding to be insecure. Therefore, in one embodiment, the electric ring-pressing binding machine further includes a ring-pressing adjustment device 600, which includes an adjustment shaft 610, a slider 620, a first switch 630, and a stop block 640. The adjustment shaft 610 is mounted on the frame 100, the slider 620 is slidably connected to the adjustment shaft 610, the first switch 630 is mounted on the slider 620 and is electrically connected to the drive motor 400, and the stop block 640 is mounted on the upper die 320 of the ring-pressing machine, and the stop block 640 has an inclined portion 641 that cooperates with the trigger end of the first switch 630. By adjusting the position of the slider 620 on the adjusting shaft 610, the position of the first switch 630 can be changed. When the upper die 320 of the pressing ring descends, the inclined part 641 on the stop block 640 cooperates with the trigger end of the first switch 630 to precisely control the start and stop of the drive motor 400, thereby accurately controlling the descent height and position of the upper die 320 of the pressing ring, ensuring that the pressing ring operation achieves the ideal effect, and avoiding the impact on binding quality due to excessive or insufficient pressing ring.

[0034] Specifically, the first switch 630 is a limit switch, a magnetic switch, an optocoupler switch, or a proximity switch.

[0035] During the operation of the binding machine, the position of the slider 620 may change, affecting the precise control of the upper die 320 of the pressure ring, and thus affecting the binding quality. Therefore, in one embodiment, the pressure ring adjusting device 600 further includes a fixing knob 650 and a retaining ring 660. One end of the fixing knob 650 is provided with a bidirectional screw, and the retaining ring 660 is disposed on the slider 620. The two ends of the retaining ring 660 are respectively threadedly connected to the bidirectional screw. By rotating the fixing knob 650, the bidirectional screw rotates accordingly. The two ends of the retaining ring 660 are threadedly connected to the bidirectional screw. The rotation of the screw changes the tightness of the retaining ring 660, thereby realizing the locking or unlocking operation of the slider 620. This prevents the slider 620 from shifting position due to machine vibration, external force interference during operation, etc., ensuring that the upper die 320 of the pressure ring works according to the preset height, stroke, etc., and ensuring the stability of the binding quality.

[0036] The cutting tool assembly 200 may exceed its travel range due to control errors, mechanical failures, or other reasons. This can damage the cutting tool assembly 200 itself, affecting its service life, and may also damage other related components of the binding machine, even causing safety hazards. Therefore, in one embodiment, the electric ring-pressing binding machine further includes a second switch 220 and a third switch 230. The second switch 220 is mounted on the frame 100, and its trigger end engages with the bottom of the cutting tool assembly 200. The second switch 220 is electrically connected to the drive motor 400. The third switch 230 is mounted on the frame 100, and its trigger end engages with the top of the cutting tool assembly 200. The third switch 230 is also electrically connected to the drive motor 400. By engaging the bottom of the cutting tool assembly 200 with the second switch 220 and the top of the cutting tool assembly 200 with the third switch 230, the position of the cutting tool assembly 200 during its vertical sliding process can be accurately monitored. When the tool assembly 200 reaches the preset stroke boundary, the corresponding switch will be triggered, and the signal will be transmitted to the drive motor 400 in time, thereby controlling the tool assembly 200 to stop moving, preventing it from exceeding the stroke, ensuring that the tool assembly 200 completes the drilling operation within the specified range, and improving the accuracy and stability of the drilling action.

[0037] Specifically, the second switch 220 and the third switch 230 are limit switches, magnetic switches, optocoupler switches, or proximity switches.

[0038] In practical applications of binding documents and other materials, different users often have diverse needs regarding binding margins. Therefore, in one embodiment, the electric ring binding machine further includes a margin adjustment device 700. The margin adjustment device 700 includes an adjustment rod 710, an adjustment bracket 720, and an adjustment block 730. The adjustment rod 710 is disposed on the frame 100 and is slidable relative to the frame 100. One end of the adjustment rod 710 is fixedly connected to the adjustment bracket 720. The adjustment bracket 720 is provided with a slanted guide rail 721. The adjustment block 730 is disposed between the cutter assembly 200 and the base plate of the frame 100. The adjustment block 730 is slidably connected to the slanted guide rail 721 and is used to abut against the edge of the paper. When the punching margin needs to be adjusted, the adjusting lever 710 is pulled left or right, causing the adjusting bracket 720 to move synchronously. The adjusting bracket 720 is equipped with a slanted guide rail 721, and the adjusting block 730 is slidably connected to the slanted guide rail 721. As the adjusting bracket 720 moves, the adjusting block 730 slides back and forth along the slanted guide rail 721. During this movement, the adjusting block 730 abuts against the edge of the paper to limit the distance between the paper edge and the cutter assembly 200. This allows the binding machine to adapt to binding more types of documents, expanding its applicability and improving its versatility.

[0039] If the paper is not placed in a fixed position or is randomly offset, the bound documents will be uneven and will not meet the binding specifications and aesthetic requirements. Therefore, in one embodiment, the electric ring binding machine further includes a positioning device 800. The positioning device 800 includes a positioning block 810 and a third guide rail 820, both mounted on the frame 100. The positioning block 810 is slidably connected to the third guide rail 820, and the positioning block 810 is used to abut against the edge of the paper. The positioning block 810 can slide along the third guide rail 820, and by abutting against the edge of the paper, it provides a positioning reference for the paper. Regardless of the size of the paper, the paper can be accurately placed according to the position of the positioning block 810, improving the accuracy and standardization of punching.

[0040] When the cutting tool assembly 200 punches holes in paper, it generates a large amount of paper scraps, which scatter inside and around the binding machine, affecting its cleanliness and appearance. Therefore, in one embodiment, the electric ring binding machine further includes a collection assembly 900. The collection assembly 900 includes a collection box 910 and a fourth guide rail 920, both mounted on the frame 100. The fourth guide rail 920 is located below the cutting tool assembly 200, and the collection box 910 is slidably connected to the fourth guide rail 920. The collection box 910, located below the cutting tool assembly 200, receives and stores the paper scraps that fall during punching, providing a centralized storage space for easy subsequent cleaning. The fourth guide rail 920 provides sliding support for the collection box 910, allowing the operator to easily remove the collection box 910 for cleaning or push it back into place to continue collecting paper scraps.

[0041] In one embodiment, the electric ring-pressing binding machine further includes an operation panel mounted on the frame 100 and electrically connected to the drive motor 400. The operation panel allows the operator to conveniently control the start, stop, and speed adjustment of the drive motor 400 via various buttons, knobs, or touch areas on the operation panel. This enables precise control of binding operations such as cutting by the cutter assembly 200 and ring pressing by the ring-pressing assembly 300, improving operational efficiency.
