Description

Technical Field

[0001] This invention relates to the field of punching equipment technology, specifically to a punching machine and a punching process. Background Technology

[0002] Punching is a process that involves using specific tools or equipment to create holes of predetermined shapes, sizes, and arrangements on fabric, thereby forming decorative, functional, or artistic patterns. A CNC punching machine (or simply punching machine) is a common piece of equipment used to perform this process. It is primarily used to punch holes in fabric according to set patterns, creating the desired designs to achieve functional requirements (such as breathability) while also enhancing aesthetics or decoration. For example, in the automotive industry, leather fabrics used in car interiors often require punching to achieve a decorative effect and significantly improve the perceived quality of the car's interior.

[0003] A pattern punching machine is a type of CNC punching machine that can punch various patterns of holes in various fabrics. It is widely used in the punching processing of leather products such as car seats, floor mats, leather shoes, leather clothing, and leather bags. Existing pattern punching machines are usually equipped with a punching platform, a punch module that can move laterally along the platform, a clamping module that can move longitudinally along the platform, and a control module. The punch module is equipped with vertically set punches, the clamping module is equipped with a template, the template is used to fix the fabric, and the control module controls the punch module and the clamping module to work together to process the required holes in the fabric on the template. Specifically, the general process of punching using an existing pattern punching machine is as follows: First, the fabric is cut into pieces of the required size. At the same time, padding paper (referred to as paper) needs to be prepared and cut into pieces suitable for the size of the fabric pieces. Then, assembly is performed. During assembly, the paper pieces are first laid on the template, then the fabric pieces are laid on the paper pieces, and finally, the paper pieces and fabric pieces are fixed together on the template. Finally, the machine is started to punch according to the preset pattern. During the punching process, the punch will leave a punch mark on the paper piece after penetrating the fabric piece (the paper piece has a certain thickness and usually will not be punched through). The paper piece not only serves to cushion and protect the fabric and the platform, but also assists in chip removal, which helps ensure punching accuracy. Furthermore, in some other punching machines, the paper piece may be directly fixed (e.g., pasted) to the platform. After punching one fabric piece, a new piece of paper needs to be replaced. In short, in existing punching processes, the paper piece is indispensable.

[0004] Currently, existing punching machines and processes suffer from severe paper waste. The main reasons are: First, existing punching machines and processes require cutting paper into pieces suitable for fabric sheets, and a new piece of paper needs to be replaced after punching each fabric sheet. Since the paper is cut into pieces, punching is typically only done near the center of the corresponding piece, leaving large areas at the edges unused, significantly reducing paper utilization. Second, in existing patterns, the spacing between punches is relatively large. For example, the hole diameter is typically 1.0-1.5mm, while the spacing between punches is usually greater than 3.5mm. Correspondingly, the spacing between adjacent punch marks on the paper sheet is also greater than 3.5mm. Because a new piece of paper needs to be replaced after punching each fabric sheet, the areas between punch marks on the paper sheet are also unused, resulting in paper waste. This leads to high paper consumption and high costs in traditional punching processes. Therefore, how to save paper and reduce the cost of punching processes urgently needs to be addressed. Summary of the Invention

[0005] The first aspect of this invention is to solve the above-mentioned technical problems by providing a punching machine that saves more paper during the punching process. This not only significantly reduces paper consumption, thereby greatly reducing costs, but also makes the punching process simpler and more efficient.

[0006] A punching machine includes a frame, a punching unit, and a control unit. The frame includes a crossbeam and a platform disposed below the crossbeam. The punching unit includes a slide table movable along the width direction of the platform and a punching module mounted on the slide table. The punching module is equipped with vertically arranged punches. The machine also includes a template unit and a paper feeding unit.

[0007] The template unit includes an adjustment module and a clamping module for holding the template. The adjustment module is connected to the clamping module for adjusting the position of the clamping module along the width direction of the platform and the position along the length direction of the platform.

[0008] The paper feeding unit includes a paper feeding module and a paper receiving module arranged opposite to each other along the length of the platform. The paper feeding module is located at the front end of the platform, and the paper receiving module is located at the rear end of the platform. The paper feeding module includes a first drive module for driving the paper to move, and the paper receiving module includes a first drive module for driving the paper to move. The paper passes through the first drive module of the paper feeding module, goes around the upper surface of the platform, and exits through the first drive module of the paper receiving module. The clamping module is located above the paper.

[0009] The punching unit, adjustment module, and first drive module are electrically connected to the control unit. The paper is pressed tightly against the platform by the cooperation of the two first drive modules, and the paper is driven to move forward or backward on the platform by the cooperation of the two first drive modules. In this solution, by configuring a paper feeding module and a paper receiving module, and through the cooperation of two first drive modules, the paper is held tightly to the platform. The position of the paper on the platform is also adjusted by the cooperation of the two first drive modules. This eliminates the need for pre-cutting of the paper during the punching process, and the paper can be used continuously. This not only effectively utilizes the large areas between paper sheets in existing technologies, thus greatly improving paper utilization, but also allows for automatic replacement of the paper under the template, making paper replacement simpler, faster, and more efficient. By configuring the clamping module to move along the width and length directions of the platform, and through the cooperation of the two first drive modules to adjust the position of the paper along the length direction of the platform, the area between two adjacent punches on the pad paper can also be effectively utilized based on the synergy of these two aspects. Compared with existing technologies, the overall paper utilization rate can be increased by more than 70%, making this punching machine very paper-saving, achieving a more energy-efficient and environmentally friendly effect, and significantly reducing the cost of the punching process.

[0010] Preferably, the template unit is positioned above the platform and below the crossbeam to ensure better punching cooperation with the punching unit and the platform.

[0011] To address the issue of paper wrinkling during the driving process, which could affect punching accuracy, the first drive module further includes a drive roller, a driven roller, and a tensioning power source. The drive roller and driven roller are connected to the frame via bearings and are arranged parallel to each other along the width of the platform. The tensioning power source is driven by the drive roller and electrically connected to the control unit. A gap exists between the drive roller and driven roller for clamping the paper. The paper passes between the drive roller and driven roller and is clamped by them. In this solution, by configuring the drive roller and driven roller in the first drive module, the paper is clamped using these rollers. The friction between the drive roller and the paper drives the paper to move relative to the drive roller, achieving the purpose of driving the paper to move forward or backward. Simultaneously, the friction between the paper and the driven roller drives the driven roller to rotate, effectively reducing the resistance during paper movement and preventing paper wrinkling. This effectively protects the paper and ensures that the paper feeding unit can deliver and adjust the paper position more smoothly, thus contributing to ensuring punching accuracy.

[0012] Furthermore, the paper feeding module also includes a paper feeding position set on the frame. The paper feeding position is used to place the paper roll assembly. The paper roll assembly typically includes a feeding shaft and a paper roll sleeved on the feeding shaft. The paper roll is detachably sleeved on the feeding shaft, and the feeding shaft is rotatably mounted on the paper feeding position. The paper roll does not contact the ground, and the paper in the paper roll passes through the first drive module. By configuring the paper feeding position and the paper roll assembly, paper can be continuously supplied to the first drive module in the paper feeding module, realizing continuous paper utilization, which is beneficial to improving punching efficiency and paper utilization rate.

[0013] Preferably, the paper feeding position includes a space for accommodating the paper feeding assembly and a constraint structure for constraining the feeding shaft. The feeding shaft is rotatably constrained by the constraint structure and arranged along the width direction of the platform.

[0014] To address the issue of facilitating the installation and replacement of the paper roll assembly, the constraint structure further includes symmetrically arranged limiting grooves on both sides of the frame. The depth of the limiting grooves is greater than or equal to the radius of the feeding shaft, and the width of the limiting grooves is greater than the diameter of the feeding shaft. The bottom of the limiting grooves is constructed as an arc-shaped structure to fit the feeding shaft, allowing the feeding shaft to be engaged within the limiting grooves and rotate within them. This not only provides rotatable constraint on the feeding shaft but also facilitates the installation and replacement of the paper roll assembly, making it extremely simple and convenient.

[0015] Furthermore, the paper receiving module also includes a paper receiving position set on the frame, which is used to place the paper receiving assembly. The paper receiving assembly includes a feed shaft and a core, which is detachably sleeved on the feed shaft and used to wind the used paper.

[0016] Preferably, the paper receiving position includes a space for accommodating the paper receiving assembly, a constraint structure for restraining the feed shaft, and a paper receiving power assembly for driving the feed shaft to rotate. The feed shaft is rotatably limited by the constraint structure. The paper receiving power assembly is drively connected to the feed shaft and electrically connected to the control unit to drive the feed shaft to rotate. This allows for the automatic and continuous winding of used waste paper, achieving the purpose of automatic waste paper winding.

[0017] Preferably, the punching unit further includes a first power source and a first linear module. The first linear module is disposed on the crossbeam and arranged along the length direction of the crossbeam. The first power source is driven to the first linear module, and the first linear module is driven to the slide table. The first power source and the first linear module are electrically connected to the control unit. The first power source drives the slide table to move linearly along the width direction of the platform through the first linear module.

[0018] Preferably, the punching module also includes a punching power source, which is mounted on the slide table, connected to the punch drive, and electrically connected to the control unit to drive the punch to perform a vertical punching action.

[0019] To address the issue of arbitrarily adjusting the template position within a horizontal plane, the preferred adjustment module comprises a second power source, a second linear module, a crossbeam, a third power source, and a third linear module. The second linear module is arranged along the length of the platform, with the second power source and the second linear module being drive-connected, and the second linear module being drive-connected to the crossbeam. The crossbeam is arranged along the width of the platform, with the third power source and the third linear module mounted on it. The third linear module is also arranged along the width of the platform, with the third power source and the third linear module being drive-connected, and the third linear module being drive-connected to the clamping module. The second and third power sources are electrically connected to the control unit. This allows for arbitrary adjustment of the clamping module position within a horizontal plane, enabling the template position to be adjusted arbitrarily to achieve the required punching fit with the punching unit. This not only meets the punching requirements but also achieves greater paper savings.

[0020] Furthermore, the adjustment module includes two symmetrically arranged second linear modules, which are respectively positioned on both sides of the platform width direction. The second power is connected to the two second linear modules for transmission. This not only allows the clamping module to have a larger operating space to meet the punching requirements of larger area fabrics, but also improves the synchronization of the two second linear modules, which is more conducive to achieving high-precision punching.

[0021] To further improve the punching progress, the adjustment module includes a synchronous shaft connected to the frame via bearings. The synchronous shaft is arranged along the width of the platform, and its two ends are respectively connected to the second linear modules on both sides. This allows the two second linear modules to be driven synchronously by a second power source. The second power source is connected to the middle of the synchronous shaft via a transmission mechanism, ensuring uniform power distribution at both ends of the synchronous shaft, ensuring synchronous operation of the two second linear modules, and thus ensuring that the crossbeam is always distributed along the width of the platform, thereby improving punching accuracy.

[0022] Preferably, the clamping module includes a clamping structure and a clamping power for clamping the template. The clamping structure is fixedly installed on the adjustment module, the clamping power is connected to the clamping structure via a transmission connection, and the clamping power is electrically connected to the control unit. The clamping structure is used to clamp or release the template.

[0023] Furthermore, the clamping module also includes a pressure plate, and the clamping structure is connected to the pressure plate in a transmission manner. The pressure plate is used to press the template.

[0024] To address the issue of paper conservation, this invention also provides a punching process, including determining whether there is space between two adjacent punches on the design drawing to accommodate at least one punch. If there is space between two adjacent punches, the punching process includes the following two steps: Step A, according to the design drawing, controlling the punching unit to punch at least two adjacent punches on the fabric and correspondingly forming adjacent punch marks on the paper; Step B, adjusting the position of the pad and / or clamping module so that the punch of the punching module is directly facing the position between two adjacent punch marks, and punching a hole at that position. This fully utilizes the area between two adjacent punch marks on the paper, thereby significantly improving paper utilization, greatly reducing costs, and achieving a more energy-efficient and environmentally friendly effect.

[0025] Furthermore, based on the punch size W in the design drawing and the center distance D between two adjacent punches, the minimum spacing d between two adjacent punches is calculated. min Compare whether the minimum distance between two adjacent punches is greater than the punch size W. If d min >W indicates that there is space between two adjacent punches to accommodate at least one punch.

[0026] Compared with existing technologies, the punching machine and punching process provided by this invention can not only significantly reduce the amount of paper used, thereby increasing the overall utilization rate of paper by more than 70%, thus greatly reducing costs and achieving a more energy-saving and environmentally friendly effect, but also make the punching process simpler and more efficient.

[0056] Fabric 9, Perforation 91. Detailed Implementation

[0057] Example 1

[0058] This embodiment provides a punching machine, including a frame 1, a punching unit 2, a template unit 3, a paper feeding unit, and a control unit. The frame 1 primarily serves a load-bearing function, acting as the mounting foundation for the other structures. The frame 1 includes a crossbeam 11 and a platform 12 disposed below the crossbeam 11, such as... Figure 1 As shown, there is sufficient spacing between the crossbeam 11 and the platform 12 to provide the necessary space for the installation and operation of the punching unit 2. For ease of description, in this embodiment, as... Figure 1 As shown, the length direction of platform 12 is the X direction, also known as the longitudinal direction; the width direction of platform 12 is the Y direction, also known as the transverse direction. In implementation, the crossbeams 11 are arranged along the width direction of platform 12, as follows: Figure 1 As shown, it is parallel to the platform 12 below; the direction perpendicular to the platform 12 is the Z direction, also known as the vertical direction.

[0059] like Figures 1-2 As shown, in implementation, the punching unit 2 includes a first power source 22, a first linear module, a slide table 21, and a punching module 24 mounted on the slide table 21. The first linear module is disposed on the crossbeam 11 and arranged along the length direction of the crossbeam 11. The first power source 22 is driven by the first linear module, and the first linear module is driven by the slide table 21, so that the first power source 22 can drive the slide table 21 to move linearly along the width direction of the platform 12 through the first linear module. In implementation, the first power source 22 can be a motor, such as a stepper motor or a servo motor. Of course, the first power source 22 can also be a pneumatic motor or other power equipment. The first linear module can be an existing conventional linear module, such as a synchronous belt 343 type linear module, a ball screw 391 type linear module, or a rack and pinion 232 type linear module. For example, in this embodiment, the first linear module is a rack and pinion 232 type linear module, which includes a rack 232 arranged along the length of the crossbeam 11, a drive gear 231 adapted to the rack 232, a guide rail 233 arranged along the length of the crossbeam 11, and a slider 234 adapted to the guide rail 233. The rack 232 and the guide rail 233... The slider 234 is movably constrained by the guide rail 233, and the slide table 21 is fixedly connected to the slider 234, so that the slide table 21 can move linearly along the guide rail 233. The first power 22 is installed on the slide table 21 and is connected to the drive gear 231. The drive gear 231 meshes with the rack 232. The first power 22 is electrically connected to the control unit and is used to drive the entire slide table 21 to move linearly along the rack 232 under the control of the control unit, so as to adjust the position of the punching module 24 along the width direction of the platform 12 according to the punching requirements.

[0060] To improve stability, it is preferable to configure at least two parallel guide rails 233 during implementation, which is more conducive to the stable support of the slide 21. In this embodiment, guide rails 233 are provided on the side of the crossbeam 11, and guide rails 233 are also provided on the top of the crossbeam 11, such as... Figures 1-2 As shown, each of the two guide rails 233 is provided with at least two sliders 234, so that the slide table 21 is connected to at least four sliders 234. The sliders 234 on different guide rails 233 are located in different positions of the crossbeam 11, which can significantly improve the anti-eccentric load capacity of the slide table 21, so that the slide table 21 has a greater load-bearing capacity and higher stability, which is beneficial to improving the punching accuracy.

[0061] In implementation, the punching module 24 includes a punching power unit 25 and a punch 26. The punching power unit 25 is mounted on the slide table 21, and the punching power unit 25 is connected to the punch 26 via a transmission connection. The punch 26 is typically arranged vertically, such as... Figure 2 As shown, the punching power unit 25 is electrically connected to the control unit and is used to drive the punch 26 to perform a vertical punching action under the control of the control unit, so as to punch the required holes in the fabric and achieve the purpose of punching. In implementation, the punching power unit 25 can be an electric motor, such as a stepper motor or a servo motor. Of course, the punching power unit 25 can also be a pneumatic motor or other power equipment.

[0062] like Figure 1 and Figure 3 As shown, in the height direction, the template unit 3 is positioned above the platform 12 and below the crossbeam 11 to form a punching fit with the punching unit 2 and the platform 12. In implementation, the template unit 3 includes an adjustment module with at least two degrees of freedom and a clamping module 4 for holding the template 43. The adjustment module is mounted on the frame 1 and is drive-connected to the clamping module 4, used to adjust the position of the clamping module 4 along the width direction and the length direction of the platform 12. In implementation, the adjustment module can adopt a planar two-dimensional adjustment structure commonly used in the prior art. In this embodiment, the adjustment module includes a second power unit 31, a second linear module, a crossbeam 37, a third power unit 38, a third linear module, and a clamping module 4 for holding the template, wherein, as... Figure 1 and Figure 3As shown, the second linear module is arranged along the length of platform 12. The second power unit 31 is driven by the second linear module, which is driven by the crossbeam 37. The second power unit 31 is electrically connected to the control unit, enabling the second power unit 31 to drive the crossbeam 37 to move linearly along the length of platform 12 via the second linear module, thereby adjusting the position of the crossbeam 37 along the length of platform 12. In implementation, the second power unit 31 can preferably be a motor, such as a stepper motor or a servo motor. The second linear module can be an existing conventional linear module, such as a synchronous belt 343 type linear module, a ball screw 391 type linear module, or a gear and rack 232 type linear module.

[0063] During implementation, both the third power unit 38 and the third linear module are mounted on the cross frame 37. The cross frame 37 is mainly used to support the third power unit 38 and the third linear module. Therefore, the existing structure of the cross frame 37 can be used during implementation. However, to better support the third linear module, the cross frame 37 can preferably adopt a long strip structure, and the cross frame 37 is arranged along the width direction of the platform 12, such as... Figure 1 and Figure 3 As shown, this provides more stable support for the third linear module, which helps improve punching accuracy.

[0064] In implementation, the third linear module is mounted on the crossbeam 37, and the third linear module is arranged along the width direction of the platform 12, such as... Figure 1 and Figure 3 As shown; in implementation, the third power unit 38 is installed on the crossbeam 37 and is connected to the third linear module via transmission. The third linear module is connected to the clamping module 4 via transmission. The third power unit 38 is electrically connected to the control unit. Under the control of the control unit, the third power unit 38 can drive the clamping module 4 to move along the width direction of the platform 12 so as to adjust the position of the clamping module 4 along the width direction of the platform 12 according to the punching requirements. At the same time, the second power unit 31 can drive the clamping module 4 to move along the length direction of the platform 12 under the control of the control unit so as to adjust the position of the clamping module 4 along the length direction of the platform 12 according to the punching requirements. This achieves the purpose of arbitrarily adjusting the position of the clamping module 4 in the horizontal plane, thereby allowing the template position to be arbitrarily adjusted in the horizontal plane to form the required punching fit with the punching unit 2. This not only meets the punching requirements but also achieves the purpose of saving paper.

[0065] Similarly, in implementation, the third power source 38 can preferably use a motor, such as a stepper motor or a servo motor. The third linear module can use existing conventional linear modules, such as the synchronous belt type 343 linear module, the ball screw type 391 linear module, and the gear and rack type 232 linear module.

[0066] In implementation, template unit 3 can be configured with one second straight line module or two second straight line modules. For example, in this embodiment, template unit 3 includes two symmetrically arranged second straight line modules, such as... Figure 3 As shown, the two second linear modules can be preferentially positioned on either side of the width of the corresponding platform 12, giving the clamping module 4 a larger operating space to meet the punching requirements of larger areas of fabric. In implementation, each of the two second linear modules can be equipped with a second power source 31, or a single second power source 31 can be used to drive the two second linear modules to move synchronously, resulting in better synchronization and facilitating high-precision punching. Figure 3 As shown, template unit 3 also includes a synchronous shaft 33, which can be connected to bearing housing 14 via bearing 13. Bearing housing 14 is connected to frame 1. The synchronous shaft 33 is arranged along the width direction of platform 12. Both ends of the synchronous shaft 33 are respectively connected to the second linear modules on both sides for transmission. The second power 31 can be set on frame 1, and can preferably be set near the middle of synchronous shaft 33 to avoid uneven load. The second power 31 is connected to synchronous shaft 33 through a transmission mechanism so as to drive the two second linear modules to move synchronously. At the same time, both ends of cross frame 37 are respectively connected to the two second linear modules for transmission. The synchronous shaft 33, the two second linear modules, and cross frame 37 can together form a rectangular structure, such as... Figure 3 As shown, the second power source 31 is connected to the middle of the synchronous shaft 33 via the transmission mechanism 32, ensuring uniform power distribution at both ends of the synchronous shaft 33, ensuring synchronous operation of the two second linear modules, and thus ensuring that the crossbeam 37 is always distributed along the width direction of the platform 12, thereby improving the punching accuracy. In implementation, the transmission mechanism can be one or a combination of gear transmission mechanisms and synchronous belt transmission mechanisms, for example, as... Figure 3 As shown, the transmission mechanism is a synchronous belt drive mechanism, which includes a driving pulley, a driven pulley, and a transmission belt. The driven pulley is sleeved at the middle position of the synchronous shaft 33. The driving pulley is connected to the output shaft of the second power 31. The transmission belt is tensioned between the driving pulley and the driven pulley, as shown. Figure 3 As shown, the second power 31 can be used to drive the synchronous shaft 33 to rotate.

[0067] More specifically, in this embodiment, the second linear module is a synchronous belt 343 type linear module, which includes a driving pulley 341, a driven pulley 342, a synchronous belt 343, a guide rail 233, a slider 234 adapted to the guide rail 233, and a movable seat 36. The driving pulley 341 is mounted on the synchronous shaft 33, the driven pulley 342 is connected to the frame 1 through a bearing 13, and the synchronous belt 343 is tensioned between the driving pulley 341 and the driven pulley 342. Figure 3As shown, the synchronous belt 343 is arranged horizontally along the length of the platform 12; the guide rail 233 is fixed to the frame 1 and arranged horizontally along the length of the platform 12, the guide rail 233 is parallel to the synchronous belt 343, the slider 234 is movably mounted on the guide rail 233 and has the freedom to move along the guide rail 233, the movable seat 36 is fixedly connected to the slider 234, and a local area of ​​the synchronous belt 343 is fixed to the movable seat 36 by the clamp 35, as shown. Figure 3 As shown, the synchronous belt 343 enables the movable seat 36 to move linearly; simultaneously, the two ends of the crossbeam 37 are respectively fixedly connected to the movable seats 36 in the second linear modules at both ends, enabling the movable seats 36 to drive the crossbeam 37 to move linearly. In actual operation, the second power 31 drives the synchronous shaft 33 to rotate, the synchronous shaft 33 drives the synchronous belt 343 to rotate, the rotation of the synchronous shaft 33 causes the movable seat 36 to move along the guide rail 233, and the movement of the movable seat 36 causes the crossbeam 37 to move back and forth along the length direction of the platform 12 to adjust the position of the clamping module 4 along the length direction of the platform 12.

[0068] More specifically, in this embodiment, as Figure 3 and Figure 4 As shown, the third linear module adopts a ball screw 391 type linear module, which includes a guide rail 233 set on the crossbeam 37, a slider 234 adapted to the guide rail 233, a ball screw 391, a nut 392, and a movable seat 393. The ball screw 391 is connected to the crossbeam 37 through a bearing 13 and is arranged along the width direction of the platform 12. The guide rail 233 is arranged along the width direction of the platform 12, and the ball screw 391 is parallel to the guide rail 233. The slider 234 is movably set on the guide rail 233, and the nut 392 is threadedly connected to the ball screw. 391. Meanwhile, nut 392 is fixedly connected to movable seat 393, and slider 234 is also fixedly connected to movable seat 393. Guide rail 233 serves to guide and prevent nut 392 from rotating with lead screw 391. In implementation, third power 38 is connected to lead screw 391 in third linear module. For example, third power 38 can be connected to one end of lead screw 391 through coupling to drive lead screw 391 to rotate. The rotation of lead screw 391 can drive movable seat 393 to move horizontally along the width direction of platform 12.

[0069] It is understandable that, during implementation, the third linear module can be installed inside the crossbeam 37 or outside the crossbeam 37, depending on the actual needs.

[0070] like Figure 3 and Figure 4As shown, in implementation, the clamping module 4 is fixedly mounted on the movable base 393, giving the movable base 393 the freedom to move along the width direction of the platform 12, so as to adjust the position of the clamping module 4 along the width direction of the platform 12. In implementation, the clamping module 4 includes a clamping structure 41 for clamping the template and a clamping power source. The clamping structure 41 is fixedly mounted on the movable base 393 in the adjustment module. The number of clamping structures 41 can be one or more to stably clamp the template. The clamping power source is drive-connected to the clamping structure 41 and electrically connected to the control unit, so that the clamping power source can drive the clamping structure 41 to clamp or release the template under the control of the control unit. In implementation, the clamping structure 41 can use existing clamps, and the clamping power source can preferably be a cylinder. Of course, to achieve a better clamping effect, the clamping module 4 is also equipped with a pressure plate 42. The clamping structure 41 can be connected to the pressure plate 42 for transmission. In actual use, the fabric 9 to be punched can be tensioned to the template. The template can be clamped to the clamping module 4 by the pressure plate 42, so that the moving seat 393 can drive the template to move horizontally synchronously through the clamping module 4. At the same time, the template is located below the punch 26 in the punching module 24, such as... Figure 1 As shown, this allows the punch 26 to punch holes in the fabric of the template.

[0071] For ease of description, in this embodiment, the two ends along the length of platform 12 are the front end and the rear end, respectively. In implementation, the paper feeding unit includes a paper feeding module 5 and a paper receiving module 6 arranged opposite each other along the length of platform 12. The paper feeding module 5 can be located at the front end of platform 12, specifically below the front end of platform 12, such as... Figure 1 As shown, correspondingly, the paper receiving module 6 can be located at the rear end of the platform 12, specifically below the rear end of the platform 12, such as... Figure 5 As shown.

[0072] In implementation, the paper feeding module 5 includes a first driving module 51 for driving the paper to move. The first driving module 51 is electrically connected to the control unit and is used to drive the paper to move forward (moving along the direction from the front end to the rear end of the platform 12, which will not be described in detail below) or backward (moving along the direction from the rear end to the front end of the platform 12) under the control of the control unit.

[0073] Similarly, in this embodiment, the paper receiving module 6 includes a first driving module 51 for driving the paper to move. The first driving module 51 is electrically connected to the control unit and is used to drive the paper to move forward (moving along the direction from the front end to the rear end of the platform 12, which will not be described in detail below) or backward (moving along the direction from the rear end to the front end of the platform 12) under the control of the control unit.

[0074] The first drive module 51 of the paper feeding module 5 is arranged opposite to the first drive module 51 of the paper receiving module 6. The paper 8 first passes through the first drive module 51 of the paper feeding module 5, goes around the upper surface of the platform 12 and is laid on the platform 12, and then passes through the first drive module 51 of the paper receiving module 6, as shown. Figure 1 , Figure 6 As shown, on platform 12, the paper is positioned below the clamping module 4 and the template, so that the paper is placed directly under the fabric to protect the punch 26. In actual use, the cooperation of the two first drive modules 51 can tension the paper 8 on platform 12, making the paper lay flatter on platform 12 and placed under the fabric, which is beneficial for achieving better punching results.

[0075] In implementation, the first drive module 51 can have multiple implementation methods, such as... Figure 1 and Figure 6 As shown, the first drive module 51 includes a drive roller 52, a driven roller 53, and a tensioning power 54. The drive roller 52 and the driven roller 53 are respectively connected to the frame 1 via bearings 13. The drive roller 52 and the driven roller 53 are arranged parallel to each other along the width direction of the platform 12, and there is a gap between the drive roller 52 and the driven roller 53 for clamping the paper. The paper passes through the drive roller 52 and the driven roller 53 and is clamped by the drive roller 52 and the driven roller 53. The tensioning power 54 can be connected to the drive roller 52 through a coupling, gear transmission mechanism, or belt transmission mechanism. For example, in this embodiment, the tensioning power 54 is fixed to the frame 1 and is a motor. The tensioning power 54 is rotatably connected to the drive roller 52 through a belt transmission mechanism so that the drive roller 52 can be driven to rotate through the belt transmission mechanism. The tensioning power 54 is electrically connected to the control unit so that the control unit can control the tensioning power 54, thereby accurately controlling the tension or movement distance of the paper. In actual use, the paper is clamped between the drive roller 52 and the driven roller 53. When the tensioning power 54 drives the drive roller 52 to rotate, the friction between the drive roller 52 and the paper can drive the paper to move relative to the drive roller 52, so as to achieve the purpose of driving the paper to move forward or backward. At the same time, the friction between the paper and the driven roller 53 can drive the driven roller 53 to rotate, thereby effectively reducing the resistance of the paper movement process and preventing the paper from wrinkling. This can effectively protect the paper and ensure that the paper feeding unit can deliver and adjust the paper position more smoothly.

[0076] In actual use, the control unit can control the two first drive modules 51 to work together. Through the coordinated cooperation of the two first drive modules 51, the paper is clamped and held firmly on the platform 12. This not only drives the paper to move forward or backward, but also allows for more precise adjustment of the paper's movement distance. This facilitates more precise adjustment of the position of the punches on the paper, thereby making full use of the paper, improving paper utilization, and achieving the goal of saving paper and reducing costs.

[0077] like Figure 7 As shown, in a more complete embodiment, the paper feeding module 5 further includes a paper feeding position 56 disposed on the frame 1. The paper feeding position 56 is used to place the paper roll assembly 55. The paper roll assembly 55 typically includes a feeding shaft 551 and a paper roll 552 sleeved on the feeding shaft 551. The paper roll typically includes a core 553 and paper wound around the outside of the core 553 in a cylindrical shape. During assembly, the paper roll 552 is detachably sleeved on the feeding shaft 551 through the core 553, so that the paper roll and the feeding shaft 551 are connected as one unit. The feeding shaft 551 is rotatably mounted on the paper feeding position 56, so that the paper roll does not contact the ground, so as to continuously supply paper to the first drive module 51 in the paper feeding module 5, which is beneficial to improving the punching efficiency. In implementation, the paper feeding position 56 includes a space for accommodating the paper feeding assembly and a constraint structure 57 for restraining the feeding shaft 551. The feeding shaft 551 is rotatably constrained by the constraint structure 57 and arranged along the width direction of the platform 12. The constraint structure 57 may be a limiting groove 571, a mounting hole 72, etc., provided on the frame 1 and located on both sides of the space. For example, Figure 1 and Figure 5 As shown, the constraint structure 57 includes limiting grooves 571 symmetrically arranged on both sides of the frame 1. The depth of the limiting grooves 571 is greater than or equal to the radius of the feeding shaft 551, and the width of the limiting grooves 571 is greater than the diameter of the feeding shaft 551. The bottom of the limiting grooves 571 is constructed as an arc-shaped structure 582 adapted to the feeding shaft 551, so that the feeding shaft 551 can be inserted into the limiting grooves 571. Figure 1 and Figure 5 As shown, it can rotate within the limiting groove 571, and a larger opening is provided above the limiting groove 571 to facilitate the installation and replacement of the feeding shaft 551. It can be understood that, in implementation, in the paper feeding module 5, the paper roll assembly 55 can passively rotate under the drive of the first drive module 51 to achieve the purpose of releasing the paper. Of course, in other embodiments, an independent drive structure can also be configured for the paper roll assembly 55 to drive the paper roll assembly 55 to rotate, achieving the purpose of automatically releasing the paper. In implementation, the drive structure can be implemented using existing technology, which will not be elaborated here.

[0078] In a simple implementation, after the used waste paper is driven by the second drive module, it passes through the second drive module of the paper collection module 6 and can be directly stacked on the ground at the rear of the platform 12, where it can be cleaned up manually later. In a more preferred implementation, such as... Figure 5 and Figure 7As shown, the paper receiving module 6 also includes a paper receiving position 61 disposed on the frame 1. The paper receiving position 61 is used to place the paper receiving assembly 62. The paper receiving assembly 62 includes a feed shaft 63 and a core 553. The core 553 is detachably sleeved on the feed shaft 63, so that the core 553 and the feed shaft 63 are connected as one unit. The paper receiving position 61 includes a space for accommodating the paper receiving assembly 62, a constraint structure 57 for constraining the feed shaft 63, and a paper receiving power assembly for driving the feed shaft 63 to rotate. The feed shaft 63 is rotatably constrained by the constraint structure 57. The constraint structure 57 may be a limiting groove 571, a mounting hole 72, etc. disposed on the frame 1 and located on both sides of the space. During assembly, the feeding shaft 63 is rotatably mounted on the constraint structure 57 of the paper feeding position 56 and arranged along the width direction of the platform 12. The core 553 is located in the space. After the feeding shaft 63 is installed, the paper take-up power assembly is connected to the feeding shaft 63 and is electrically connected to the control unit so that the control unit can control the paper take-up power assembly, so that the paper take-up power assembly can drive the feeding shaft 63 to rotate under the control of the control unit, so as to automatically and continuously wind the used waste paper to achieve the purpose of automatically winding the waste paper. In implementation, the paper delivery power assembly can be implemented using existing technology. For example, the paper delivery power assembly includes a motor, an active friction wheel connected to the motor, and a driven friction wheel disposed on the feed shaft 63. The motor is electrically connected to the control unit. The active friction wheel is disposed next to the constraint structure 57 (such as the limiting groove 571) (as shown below). When the feed shaft 63 is constrained within the constraint structure 57 (such as the limiting groove 571), the driven friction wheel is in contact with the active friction wheel, allowing the active friction wheel to drive the driven friction wheel to rotate through friction, thereby driving the feed shaft 63 to rotate and achieving the purpose of automatically winding the padding paper. In implementation, both the feed shaft 551 and the feed shaft 63 can preferably use existing air expansion tubes to tighten the core 553 by air expansion, which will not be elaborated here.

[0079] The punching machine provided in this embodiment has a control unit that controls two first drive modules 51 to work together to precisely adjust the position of the paper along the length of the platform 12; controls the first power 22 to precisely adjust the position of the punch head along the width of the platform 12; controls the second power 31 to simultaneously and precisely adjust the position of the template and the material on the template along the length of the platform 12; and controls the third power 38 to simultaneously and precisely adjust the position of the template 43 and the material on the template along the width of the platform 12. This allows the paper feeding unit, the punching unit 2, and the template unit 3 to work together to achieve high-precision punching on the material. The entire process does not require paper cutting, which greatly simplifies the process flow and enables continuous use of paper, significantly improving paper utilization and achieving the goals of saving paper and reducing costs.

[0080] To further reduce paper consumption, based on the punching machine provided in this embodiment, this embodiment also provides a method of using the punching machine, specifically a process method that saves more paper during the punching process. This includes determining whether there is space between two adjacent punches on the design drawing to accommodate at least one punch. If there is space between two adjacent punches, the punching process includes the following two steps: Step A, according to the design drawing, control the punching unit 2 to punch at least two adjacent punches on the fabric and correspondingly form adjacent punch marks 81 on the paper; Step B, adjust the position of the pad and / or clamping module 4 so that the punch 26 of the punching module 24 is directly opposite the position between the two adjacent punch marks 81, and punches a hole at that position. This fully utilizes the area between the two adjacent punch marks 81 on the paper, thereby significantly improving paper utilization, greatly reducing costs, and achieving a more energy-efficient and environmentally friendly effect. It is understood that in implementation, ensuring step A comes first and step B comes later is sufficient.

[0081] To facilitate understanding, a more specific embodiment is provided. For example, a batch (or multiple batches) of fabric needs to be processed, and a rectangular pattern (i.e., a design drawing) consisting of a 30×20 perforation array needs to be processed on the fabric. In the rectangular pattern, the size W of the perforation is generally 1.0 to 1.5 mm (for example, when the perforation is a round hole, the size is the diameter of the perforation; when the perforation is a square hole or other irregularly shaped hole, the size is the diagonal length of the perforation). As an example, the perforation is a round hole, and the diameter W of the perforation is 1.5 mm. The center distance D between two adjacent perforations is generally 3.0 to 5.0 mm. As an example, the center distance D between two adjacent perforations is 3.5 mm.

[0082] Based on this, according to the punching machine provided in this embodiment, a paper-saving process may include the following steps:

[0083] Step S1, material preparation. This includes placing the fabric 9 on the template 43 of the punching machine and fixing the template to the template unit 3, so that the template is above the platform 12 and below the punch 26 in the punching unit 2; it also includes passing the paper sequentially through the first drive module 51 of the paper feeding unit, the platform 12, and the first drive module 51 of the paper receiving module 6, with the paper tightly between the two first drive modules 51, and the paper between the template and the platform 12 kept flat to cooperate with the punch 26, such as... Figure 8 and Figure 9 As shown.

[0084] Step S2, determining whether there is space between two adjacent punches to accommodate at least one punch, specifically includes obtaining the design drawing (including but not limited to template drawing, pattern drawing, or pattern drawing, etc.), and calculating the minimum spacing d between two adjacent punches based on the punch size W in the design drawing (i.e., the graphic of the punches required on the fabric) and the center distance D between two adjacent punches. min=DW=2.0mm, compare whether the minimum distance between two adjacent punches is greater than the punch size W. If d min >W indicates that there is space between two adjacent punches to accommodate at least one punch, that is, there is space between two adjacent punch marks 81 to accommodate at least one punch mark 81, then continue to execute step S3; if d min If ≤W, it indicates that there is no space between two adjacent punches to accommodate the punches, then proceed to step S4.

[0085] Step S3: Determine the number N of holes that can be accommodated between two adjacent holes on the design drawing; since the minimum spacing d between two adjacent holes... min =2.0mm, punching hole size W=1.5mm, .

[0086] Step S4: Plan the punching strategy along the width of platform 12. Since the design drawing shows that one punch can be accommodated between two adjacent punches, in implementation, the punch can be preferentially positioned in the middle of two adjacent punches. At this time, on the paper, the distance between two adjacent punch marks 81 is F=D / 2=1.75mm. Therefore, the punching strategy along the width of platform 12 includes: controlling the punching unit 2 to punch at intervals W along the width of platform 12 to complete the punching work of the first row of punches on the fabric, such as... Figure 10 and Figure 11 As shown, template unit 3 needs to control the template to move the fabric a distance of D / 2 towards the rear end of platform 12, and also needs to control the template to move the fabric a distance of F along the width direction of platform 12. Correspondingly, punching unit 2 needs to move a distance of F in the same direction as the fabric movement, as shown. Figure 12 As shown, the punching unit 2 can then punch holes at intervals of W along the width direction of the platform 12, completing the punching work of the second row of holes on the fabric, as shown. Figure 13 As shown, at this point, only one row of punch marks 81 is formed on the paper below the fabric, and the distance between two adjacent punch marks 81 is F=D / 2, as shown. Figure 14 As shown, this achieves the goal of making full use of paper.

[0087] Step S5: Plan the punching strategy along the length of platform 12. After fully utilizing one row of space on the paper, the paper needs to be moved. Since the design drawing allows for one punch between two adjacent punches, the spacing between two adjacent punch marks 81 on the paper can be F=D / 2=1.75mm. Therefore, the punching strategy along the length of platform 12 includes: after completing the punching of two rows of punches on the fabric, controlling the two first drive modules 51 to drive the paper to translate a distance F along the rear end of platform 12, and then repeating the aforementioned punching strategy along the width of platform 12 to complete the punching of the third and fourth rows of punches on the fabric, and so on, as follows. Figure 15 and Figure 16 As shown.

[0088] Step S6: Determine an initial punching point. The initial punching point is typically the location of a punch at the edge of the graphic on the design drawing, and there should be no punch marks on the paper below this initial punching point 81; if d min If the value is greater than W, then the punching machine will be controlled to perform punching operations according to the planned punching strategy, starting from the initial punching point, until the desired pattern is obtained on the fabric, such as... Figure 15 As shown. If d min If W ≤ W, then punching operation is performed according to the existing punching strategy. The existing punching strategy is as follows: (1) Control the punching unit 2 to punch at intervals W along the width direction of the platform 12 to complete the punching work of the first row of punches on the fabric; (2) Then the template unit 3 controls the template to move the fabric to the rear end of the platform 12 by a distance D; (3) Then control the punching unit 2 to punch at intervals W in the opposite direction along the width direction of the platform 12 to complete the punching work of the second row of punches on the fabric; (4) Then the template unit 3 controls the template to move the fabric to the rear end of the platform 12 by a distance D; repeat (1)-(4) until the required pattern is obtained on the fabric.

[0089] like Figure 15 and Figure 16 As shown, after punching a piece of fabric, the area of ​​the pattern formed by the punch marks 81 on the paper is only about 25% of the area of ​​the pattern on the fabric. This means that punching a piece of fabric using this method requires only 1 / 4 of the paper used by traditional punching methods, thus significantly reducing paper consumption and achieving the goals of paper saving and cost reduction. In this specific embodiment, only one additional punch can be accommodated between two adjacent punches, increasing paper utilization by more than 70%. It can be understood that when two or three additional punches can be accommodated between two adjacent punches, the paper utilization will be even higher, and the paper-saving effect will be even more significant.

[0090] In addition, according to the punching machine provided in this embodiment, another paper-saving process may include the following steps: Step S1, same as above; Step S2, same as above, if there is no space to accommodate the punch between two adjacent punches, then the punching operation is carried out according to the existing punching strategy; Step S3, same as above, taking N=1 as an example, at this time, Step S4, an initial punching point is determined. At this time, the position of the paper is the initial position, and the position of the clamping module 4 is also the initial position. Then, the punching machine is controlled to complete all the punching work of the first sheet of fabric. At this time, a 30×20 punch mark 81 array will be formed on the paper; Step S5, the first sheet of fabric is removed and the second sheet of fabric is installed; Step S6, the paper is adjusted back to the initial position, the clamping module 4 is adjusted to the position horizontally offset from the initial position by D / 2, and the punching module 24 is adjusted to the position horizontally offset from the initial punching point by D / 2. At this time, the punch 26 is directly opposite the position between two adjacent punch marks 81 on the paper. Starting from this position, the punching machine is controlled. Complete all punching work on the second fabric; Step S7, remove the second fabric and install the third fabric; Step S8, adjust the paper to the initial position offset by D / 2 along the length of platform 12, adjust the punching module 24 to the initial punching point, adjust the clamping module 4 to the initial position, and then control the punching machine to complete all punching work on the third fabric; Step S9, remove the third fabric and install the fourth fabric; Step S10, adjust the paper to the initial position offset by D / 2 along the length of platform 12, adjust the clamping module 4 to the initial position offset by D / 2 horizontally, and adjust the punching module 24 to the initial punching point offset by D / 2 horizontally. At this time, the punch 26 is directly opposite the middle of two adjacent punch marks 81 on the paper. Starting from this position, control the punching machine to complete all punching work on the fourth fabric; Repeat steps S4-S10 to make full use of the space on the paper, increasing the paper utilization rate by more than 70%.

[0091] Example 2

[0092] To address the issue of more stable fabric clamping and prevent manufacturing and assembly errors from affecting punching quality and accuracy, the main difference between this embodiment 2 and embodiment 1 is that the punching machine provided in this embodiment, such as Figures 17-19 As shown, the first drive module 51 also includes two elastic clamping mechanisms 7. The two ends of the driven roller 53 are rotatably connected to the two elastic clamping mechanisms 7. The two elastic clamping mechanisms 7 are respectively set on the frame 1. The elastic clamping mechanism 7 is used to provide elastic pressure to the driven roller 53 toward the driving roller 52. Under the elastic force of the elastic clamping mechanism 7, the driven roller 53 clamps the fabric between the driven roller 53 and the driving roller 52.

[0093] The elastic clamping mechanism 7 has various implementations. As one example, the elastic clamping mechanism 7 includes a slide 71 and an elastic component 74. The slide 71 is provided with a mounting hole 72. The driven roller 53 is connected to the mounting hole 72 of the slide 71 via a bearing 13, allowing the driven roller 53 to have a degree of freedom of rotation relative to the slide 71. Simultaneously, the slide 71 is also provided with a constraint part 73, and the frame 1 is provided with a guide part 15 adapted to the constraint part 73. The slide 71 forms a sliding pair through the cooperation of the constraint part 73 and the guide part 15, and the driven roller 53 is located on one side of the driving roller 52, allowing the driven roller 53 to approach or move away from the driving roller 52. The elastic component 74 is located on the side opposite to the driving roller 52. One end of 4 is connected to the slide block 71, and the other end is connected to the frame 1, so that the elastic component 74 can provide the slide block 71 with an elastic force close to the drive roller 52, so that the driven roller 53 can continuously and tightly clamp the paper under the elastic force of the elastic component 74. On the one hand, by configuring the elastic component 74 with different elastic forces, the clamping force between the driven roller 53 and the drive roller 52 can be changed to meet the needs of different paper thicknesses and different clamping force occasions. On the other hand, it can provide a continuous clamping force to the driven roller 53, preventing the paper from not being clamped tightly due to manufacturing errors and assembly errors, which would cause the paper to slip during the drive process, and the paper position not to be adjusted properly, thus seriously affecting the punching quality and punching accuracy.

[0094] In implementation, the elastic component 74 can be a spring, but in the preferred embodiment provided in this example, the elastic component 74 is a cylinder, such as... Figures 17-19 As shown. The cylinder is connected to the control unit so that the pressure of the cylinder can be precisely controlled, thereby adjusting and controlling the clamping force between the driven roller 53 and the driving roller 52 according to actual needs, avoiding the problem of frequent replacement due to mismatched spring force.

[0095] In implementation, the guide part 15 can be a guide rail 233 disposed on the frame 1, and correspondingly, the constraint part 73 is a slider 234 adapted to the guide rail 233; the guide part 15 can also be a guide rod disposed on the frame 1, and correspondingly, the constraint part 73 is a guide hole adapted to the guide rod. For example, Figures 17-19 As shown, the guide part 15 is a guide slot constructed in the side plate of the frame 1, and the constraint part 73 is a guide groove adapted to the guide slot, as shown. Figures 17-19 As shown, this facilitates a simpler structure and lower costs.

[0096] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
