Description

Technical Field

[0001] This utility model belongs to the field of garment processing technology, specifically relating to a garment fabric cutting, positioning, and punching device. Background Technology

[0002] In garment processing, fabric needs to be cut into pieces. To ensure cutting quality, positioning holes are usually drilled at the cutting inflection points before cutting. Excluding expensive fully automatic slicing machines, the tools currently used for drilling positioning holes in garment fabric are mostly handheld drilling devices. The basic structure of this device involves pressing the fabric down against a pressure head and then pressing it against the machine frame, causing the drill bit fixed to the frame to pass through a guide hole in the center of the pressure head and drill a positioning hole in the fabric. The process is then repeated at the next point.

[0003] The drawbacks of existing drilling equipment are that it requires frequent manual movement, resulting in high labor intensity. Furthermore, operators must visually align the drill bit with the drilling point during drilling, which is prone to positional errors and visual fatigue. Therefore, it is necessary to improve manual drilling equipment to address these issues. Utility Model Content

[0004] This utility model provides a device for cutting, positioning, and punching holes in clothing fabric, which aims to reduce the labor intensity of manual punching operations and improve the accuracy of punching position.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a clothing fabric cutting, positioning, and punching device, comprising: The gantry frame is mounted across the cutting platform and moves along the length of the cutting platform; The punching mechanism is slidably connected to the gantry frame and has a punching rod that moves vertically downward to punch or drill holes in the clothing fabric stacked on the cutting platform. The drive mechanism, located on the gantry traveling frame and connected to the punching mechanism, is used to drive the punching mechanism to slide along the width direction of the cutting platform; A laser emitter, located on the punching mechanism and to the side of the punching rod, is used to emit a laser towards the fabric of the garment and form a positioning light spot on the fabric. The lower end of the punch rod coincides with the positioning light point when it comes into contact with the fabric of the garment.

[0006] In one possible implementation, the punching mechanism includes: A connecting seat is slidably connected to the gantry frame, and the connecting seat is provided with a connecting bracket for mounting a laser emitter; The telescopic drive component is fixedly connected to the connector with its output end facing downwards. The lifting frame is vertically slidably connected to the connecting seat and connected to the output end of the telescopic drive component; The rotary drive component is fixedly connected to the lifting frame and has a detachable perforated rod at its output end.

[0007] In some embodiments, the connecting frame includes a first connecting plate and a second connecting plate; one end of the first connecting plate is fixedly connected to the connecting seat, and the other end extends beyond the boundary of the connecting seat along the length direction of the cutting platform; one end of the second connecting plate is fixedly connected to the extended end of the first connecting plate, and the other end extends downward at an angle. The laser emitter is fixed to the second connecting plate and aligned with the punching rod along the length of the cutting platform; the first connecting plate has a connecting hole extending along the length of the cutting platform, and a fastener connected to the connecting seat passes through the connecting hole.

[0008] For example, the punching mechanism also includes a fabric pressing frame, which is vertically slidably connected to the lower part of the lifting frame, and a first elastic member is provided between the fabric pressing frame and the lifting frame. The first elastic member is used to push the fabric pressing frame downward so that the fabric pressing frame elastically presses against the clothing fabric.

[0009] For example, the pressing frame includes a pressing plate and two guide columns. The two guide columns are vertically connected to both ends of the pressing plate, and both guide columns are slidably connected to the lifting frame along their respective axes. A first elastic element is sleeved on each of the two guide columns. The center of the pressing plate is provided with a drill sleeve suitable for the drilling rod to pass through.

[0010] In one possible implementation, the drive mechanism includes a pull cable, two unidirectional rope threaders, several guide wheels, and a drive wheel; wherein... Two unidirectional rope threaders are placed on both sides of the punching mechanism along the length of the cutting platform. Each guide wheel is located at each corner of the gantry frame. The pull line passes through the two rope threaders and the drive wheel based on the guiding action of each guide wheel. A one-way rope threader is used to provide the pull wire with a unidirectional degree of freedom of movement, and the pull wire has opposite directions of movement in the two one-way rope threaders; the drive wheel exerts a traction force on the pull wire in the corresponding direction based on its rotation direction.

[0011] In some embodiments, the unidirectional threader includes: The sleeve is fixedly connected to one side of the punching mechanism and has a rope threading hole that runs through it along the length of the cutting platform. Several elastic clips are distributed at intervals along the circumference of the sleeve in the rope hole. One end of the elastic clip is hinged to the sleeve, and the other end extends obliquely to elastically press against the pull line.

[0012] For example, a ring cavity is provided in the middle of the rope hole, each elastic clip is hinged to one side of the ring cavity wall, and a second elastic element is provided between the elastic clip and the ring cavity wall. The end of the elastic clip away from its hinge part forms a toothed surface, which is used to press against the pull wire.

[0013] For example, drive wheels include: The first clamping plate has a central shaft, one end of which is rotatably connected to the gantry traveling frame, and the other end is equipped with a crank handle; The pressure plate, ring-shaped handle, and fixed to the central shaft; The second clamping plate is slidably mounted on the central shaft and located between the pressure plate and the first clamping plate. A clamping groove is formed between the second clamping plate and the first clamping plate. Multiple connecting posts are distributed around the central shaft on the second clamping plate. Each connecting post passes through the pressure plate and is connected to a lock nut. A third elastic element is mounted on each connecting post.

[0014] In some embodiments, the garment fabric cutting, positioning, and punching device also includes a controller, which is located at one end of the gantry frame and electrically connected to the punching mechanism.

[0015] The advantages of this invention's garment fabric cutting, positioning, and punching device are as follows: Compared with existing technologies, this invention utilizes a gantry frame straddling the cutting platform as the mounting base for the punching mechanism. By moving the gantry frame along the length of the cutting platform and allowing the punching mechanism to slide along the width of the platform, the punching mechanism can be moved to any position on the cutting platform. The operator only needs to push the gantry frame and operate the drive mechanism from one side of the cutting platform, significantly reducing labor intensity compared to the traditional method of manually moving the punching mechanism. Because the positioning light spot formed by the laser emitter on the fabric coincides with the lower end of the punching rod when it touches the fabric, the position of the positioning light spot is the punching position of the punching rod on the fabric. Therefore, the punching position can be determined by observing the positioning light spot when moving the punching mechanism. Compared with the existing technology that requires observing whether the punching rod is aligned with the positioning mark, the positioning light spot formed by the laser emitter has a higher contrast with the fabric. This not only alleviates the visual fatigue of the operator, but also helps to improve the alignment accuracy of the positioning mark, thereby improving the punching position accuracy of the fabric.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0020] Please refer to the following: Figures 1 to 6 The present invention provides a device for cutting, positioning, and punching clothing fabrics. The device includes a gantry frame 10, a punching mechanism 20, a drive mechanism 30, and a laser emitter 40.

[0021] The gantry frame 10 spans across the cutting platform 60 and moves along the length of the cutting platform 60; the punching mechanism 20 is slidably connected to the gantry frame 10 and has a punching rod 200 that moves vertically downward to punch or drill holes in the fabric of the garment stacked on the cutting platform 60.

[0022] The drive mechanism 30 is mounted on the gantry frame 10 and connected to the punching mechanism 20, and is used to drive the punching mechanism 20 to slide along the width direction of the cutting platform 60; the laser emitter 40 is mounted on the punching mechanism 20 and located to the side of the punching rod 200, and is used to emit laser towards the clothing fabric and form a positioning light spot 400 on the clothing fabric; wherein, the lower end of the punching rod 200 coincides with the positioning light spot 400 when it touches the clothing fabric.

[0023] It should be noted that perforation methods for clothing fabrics typically include punching and drilling. Punching is more commonly used for single-layer or minimally layered clothing fabrics, while drilling is more commonly used for clothing fabrics with multiple layers. Regardless of whether punching or drilling is used, the perforation mechanism 20 employed in this embodiment can adopt the same structural form as existing technologies, the only difference being that it is mounted on the gantry frame 10 via a sliding connection.

[0024] In this embodiment, the installation method of the gantry traveling frame 10 and the cutting platform 60 can be based on the rollers on both sides clamping the two sides of the roller cutting platform 60 in the width direction respectively. Considering the walking stability, at least two pairs of rollers are provided on each side.

[0025] The purpose of the laser emitter 40 is to emit a laser beam that illuminates the fabric of the garment, thereby forming a light spot, namely the positioning light spot 400, on the fabric. Before the actual punching operation, the slicing template is usually laid flat on the fabric of the garment. The slicing template has markings on the positions where punching is required, namely the positioning marking points. Before punching, the laser emitter 40 is first adjusted.

[0026] The specific adjustment method is to press down the punching rod 200 of the punching mechanism 20 until it is in contact with the slicing template, and then adjust the laser emitter 40 so that it coincides with the lower end of the punching rod 200; or, first make the punching mechanism 20 punch holes in the remaining material of the clothing fabric, and then raise the punching rod 200 to the initial position and adjust the laser emitter 40 so that the positioning light spot 400 formed by the laser emitter 40 coincides with the hole position.

[0027] It should be explained that the drive mechanism 30 in this embodiment can be electrically driven or manually driven. Considering that electric drive requires complex control programs and coordinate calculations, and this application is intended to be developed for manual drilling scenarios with small batch operations, the latter method, i.e., manually operating the drive mechanism 30 to output power, is preferred. Specifically, the drive mechanism 30 can be a lead screw and nut pair that drives the drilling mechanism 20 to move, or a telescopic rod that drives the drilling mechanism 20 to move, or a traction member that drives the drilling mechanism 20 to move.

[0028] The drive mechanism 30 can be set at one end of the gantry frame 10, or it can be set at both ends to improve operational flexibility. The movement of the gantry frame 10 on the cutting platform 60 can be driven by a single person on one side or by two people on both sides.

[0029] Compared with the prior art, the garment fabric cutting and positioning punching device provided in this embodiment utilizes a gantry frame 10 straddling the cutting platform 60 as the mounting base for the punching mechanism 20. By moving the gantry frame 10 along the length of the cutting platform 60 and sliding the punching mechanism 20 along the width of the cutting platform 60 on the gantry frame 10, the punching mechanism 20 can be moved to any position on the cutting platform 60. The operator only needs to push the gantry frame 10 and operate the drive mechanism 30 from one side of the cutting platform 60, which greatly reduces labor intensity compared to the traditional method of manually moving the punching mechanism 20. Because the laser emitter 40 is located on the garment fabric... When the positioning light spot 400 formed on the fabric and the lower end of the punching rod 200 abut against the fabric, they coincide. Therefore, the position of the positioning light spot 400 is the punching position of the punching rod 200 on the fabric. Thus, the punching position can be determined by observing the positioning light spot 400 when the punching mechanism 20 is moved. Compared with the existing technology that requires observing whether the punching rod 200 is aligned with the positioning mark, the positioning light spot 400 formed by the laser emitter 40 has a higher contrast with the fabric. This not only alleviates the visual fatigue of the operator, but also helps to improve the alignment accuracy of the positioning mark, thereby improving the punching position accuracy of the fabric.

[0030] In some embodiments, see Figure 2 and Figure 3 The drilling mechanism 20 includes a connecting seat 21, a telescopic drive component 23, a lifting frame 24, and a rotary drive component 25. The connecting seat 21 is slidably connected to the gantry traveling frame 10, and the connecting seat 21 is provided with a connecting frame 22 for installing the laser emitter 40. The telescopic drive component 23 is fixedly connected to the connecting seat 21 with its output end facing downward. The lifting frame 24 is vertically slidably connected to the connecting seat 21 and connected to the output end of the telescopic drive component 23. The rotary drive component 25 is fixedly connected to the lifting frame 24, and its output end is detachably connected to a drilling rod 200.

[0031] Specifically, the telescopic drive component 23 can be an electric push rod, and the rotary drive component 25 can be a motor. The connection between the connecting seat 21 and the gantry frame 10 can be achieved by having two sliding grooves spaced apart and opposite each other along the length of the cutting platform 60 on the gantry frame 10, with the two sides of the connecting seat 21 respectively slidingly embedded in one of the sliding grooves. The sliding connection between the lifting frame 24 and the connecting seat 21 can be achieved by using the sliding column on the lifting frame 24 and the sliding sleeve on the connecting seat 21. The drilling rod 200 is equivalent to the drill rod of a drilling machine in the prior art. The output end of the rotary drive component 25 is provided with an openable clamp to clamp and fix the drilling rod 200 and to flexibly replace the drilling rod 200.

[0032] In actual operation, the rotary drive 25 can always be kept open. When the drilling mechanism 20 moves to the position light point 400 and the mark point, the telescopic drive 23 pushes the lifting frame 24 downward so that the drilling rod 200 is aligned with the position light point 400 to drill. This not only makes the operation simple and labor-saving, but also improves the drilling position accuracy.

[0033] As one specific embodiment of the connecting bracket 22 described above, please refer to Figure 3 and Figure 4 The connecting frame 22 includes a first connecting plate 221 and a second connecting plate 222; one end of the first connecting plate 221 is fixedly connected to the connecting seat 21, and the other end extends beyond the boundary of the connecting seat 21 along the length direction of the cutting platform 60; one end of the second connecting plate 222 is fixedly connected to the extended end of the first connecting plate 221, and the other end extends downward at an angle.

[0034] The laser emitter 40 is fixed to the second connecting plate 222 and aligned with the punching rod 200 along the length of the cutting platform 60; the first connecting plate 221 is provided with a connecting hole 2211 extending along the length of the cutting platform 60, and a fastener 2212 connected to the connecting seat 21 is inserted into the connecting hole 2211.

[0035] The connecting frame 22 forms a V-shaped structure based on the first connecting plate 221 and the second connecting plate 222, thereby enabling the laser emitter 40 to be tilted on the second connecting plate 222. This allows it to avoid the punching mechanism 20 and enable the laser beam emitted by the laser emitter 40 to illuminate the clothing fabric to form a positioning light spot 400.

[0036] Since the laser emitter 40 and the punching rod 200 are aligned along the length of the cutting platform 60, the positioning light spot 400 can change in the height direction when the first connecting plate 221 is adjusted along the length of the connecting hole 2211. This allows for positioning of clothing fabrics of different thicknesses, thereby improving applicability.

[0037] For some possible implementations, please refer to [link / reference]. Figure 2 The punching mechanism 20 also includes a fabric pressing frame 26, which is vertically slidably connected to the lower part of the lifting frame 24. A first elastic element 2621 is provided between the fabric pressing frame 26 and the lifting frame 24. The first elastic element 2621 is used to push the fabric pressing frame 26 downward so that the fabric pressing frame 26 elastically presses against the clothing fabric. By setting the fabric pressing frame 26, the clothing fabric around the punching position can be elastically pressed, thereby avoiding the clothing fabric from wrinkling and deforming, which would affect the accuracy of the punching position and the punching quality.

[0038] As an optional structural form of the aforementioned fabric pressing frame 26, please refer to Figure 2The pressing frame 26 includes a pressing plate 261 and two guide posts 262. The two guide posts 262 are vertically connected to both ends of the pressing plate 261, and both guide posts 262 are slidably connected to the lifting frame 24 along their respective axes. A first elastic element 2621 is sleeved on each of the two guide posts 262. The center of the pressing plate 261 is provided with a drill sleeve 2611 suitable for the drilling rod 200 to pass through.

[0039] When punching, the lifting frame 24 first drives the pressing frame 26 to descend together. When the pressing plate 261 presses against the fabric, the first elastic element 2621, like a spring, begins to be compressed, and the pressing plate 261 stops descending. When the punching is completed, the process of the punching rod 200 rising and retracting ensures that the pressing plate 261 can always press against the fabric due to the release of the elastic force of the first elastic element 2621. The pressing plate 261 then rises and resets together with the lifting frame 24 after the punching rod 200 is completely removed. This avoids the punching rod 200 pulling the fabric upwards during the retraction process, which would affect the accuracy of the punching position in the next step.

[0040] For specific details, please refer to the following for easier operation: Figure 2 , Figure 5 and Figure 6 In this embodiment, the drive mechanism 30 includes a pull wire 31, two one-way rope threaders 32, several guide wheels 33, and a drive wheel 34. The two one-way rope threaders 32 are positioned on both sides of the punching mechanism 20 along the length of the cutting platform 60. Each guide wheel 33 is located at each corner of the gantry frame 10. The pull wire 31 passes through the two rope threaders and the drive wheel 34 based on the guiding effect of each guide wheel 33. The one-way rope threaders 32 provide the pull wire 31 with a unidirectional degree of freedom of movement, and the movable directions of the pull wire 31 in the two one-way rope threaders 32 are opposite. The drive wheel 34 exerts a traction force on the pull wire 31 in a corresponding direction based on its rotation direction.

[0041] By turning the drive wheel 34 clockwise, a traction force is generated on the pull cable 31 to move clockwise around the gantry frame 10. At this time, the pull cable 31 drives the punching mechanism 20 to move through one of the one-way rope threaders 32, while the pull cable 31 slides in the opposite direction to the movement of the punching mechanism 20 in the other one-way rope threader 32. When the drive wheel 34 is turned counterclockwise, the traction force generated on the pull cable 31 is reversed. At this time, the pull cable 31 changes from the previous sliding state to the locked state in one of the one-way rope threaders 32, and changes from the previous locked state to the sliding state in the other one-way rope threader 32. Thus, the pull cable 31 drives the punching mechanism 20 to move in the opposite direction through the locked one-way rope threader 32.

[0042] By turning the drive wheel 34, the pull wire 31 can drive the punching mechanism 20 to move on the gantry frame 10, thereby adjusting the position of the punching mechanism 20 in the width direction of the cutting platform 60. The operation is simple and labor-saving.

[0043] For example, such as Figure 5 As shown, the unidirectional rope threader 32 includes a sleeve 321 and several elastic clips 322; the sleeve 321 is fixedly connected to one side of the punching mechanism 20 and has a rope threading hole 3211 extending through it along the length of the cutting platform 60; each elastic clip 322 is distributed circumferentially in the rope threading hole 3211 along the sleeve 321, one end of the elastic clip 322 is hinged to the sleeve 321, and the other end extends obliquely and is used to elastically press against the pull wire 31.

[0044] When the pull wire 31 moves away from the hinge end of the elastic clip 322 in the rope hole 3211, the elastic clip 322 cannot lock the pull wire 31 due to the force that drives it to swing away from the center of the pull wire 31. When the pull wire 31 receives a reverse traction force, the force on the elastic clip 322 is towards the center of the pull wire 31. Therefore, each elastic clip 322 will tighten and lock the pull wire 31, so that the pull wire 31 can only move through the rope hole 3211 in one direction. The structure is simple and reliable.

[0045] It should be noted that, as Figure 5 As shown, the above-mentioned rope hole 3211 has an annular cavity 3212 in the middle. Each elastic clip 322 is hinged to one side wall of the annular cavity 3212. A second elastic element 323 is provided between the elastic clip 322 and the wall of the annular cavity 3212. The end of the elastic clip 322 away from its hinged part forms a toothed surface 3221, which is used to press against the pull wire 31.

[0046] By setting the annular cavity 3212 to form a space that can accommodate the elastic locking element 322, it is ensured that the portion of the rope hole 3211 located on both sides of the annular cavity 3212 can effectively constrain the pull wire 31, which is beneficial to improving the stability of the pull wire 31 passing through the rope hole 3211; the second elastic element 323 can be a torsion spring sleeved on the hinge shaft of the elastic locking element 322, or a spring piece clamped between the elastic locking element 322 and the peripheral wall of the annular cavity 3212; by setting the toothed surface 3221, the locking reliability of the elastic locking element 322 on the pull wire 31 can be improved.

[0047] For example, please refer to Figure 6The aforementioned drive wheel 34 includes a first clamping plate 341, a second clamping plate 342, and a pressure plate 343. The first clamping plate 341 has a central shaft 3411, one end of which is rotatably connected to the gantry traveling frame 10, and the other end is provided with a crank handle 3412. The pressure plate 343 is fitted around the crank handle 3412 and fixed to the central shaft 3411. The second clamping plate 342 is slidably fitted onto the central shaft 3411 and is located between the pressure plate 343 and the first clamping plate 341, forming a clamping groove 3421 between the second clamping plate 342 and the first clamping plate 341. The second clamping plate 342 has a plurality of connecting posts 3422 spaced around the central shaft 3411. Each connecting post 3422 passes through the pressure plate 343 and is connected to a lock nut 3423. Each connecting post 3422 is fitted with a third elastic element 3424.

[0048] The cooperation of the pressure plate 343 and each of the third elastic elements 3424 applies an elastic pushing force to the second clamping plate 342, thereby enabling the second clamping plate 342 and the first clamping plate 341 to form an elastic clamping force on the pull cable 31 portion passing through the clamping groove 3421. This allows the pull cable 31 to obtain traction force when the crank handle 3412 drives the central shaft 3411 to rotate. Simultaneously, considering that a greater clamping force results in greater resistance for the pull cable 31 entering and exiting the clamping groove 3421, the clamping force of the clamping groove 3421 is adjusted by turning each lock nut 3423. This minimizes the clamping force while preventing the pull cable 31 from slipping within the clamping groove 3421, thereby reducing the rotational resistance of the drive wheel 34 and ensuring convenient and effortless operation.

[0049] In some embodiments, such as Figure 2 As shown, the garment fabric cutting, positioning, and punching device also includes a controller 50, which is located at one end of the gantry frame 10 and electrically connected to the punching mechanism 20. The controller 50 can be equipped with switches and buttons to control the punching mechanism 20. Specifically, it should include buttons to control the rotation of the punching rod 200 (i.e., the start and stop of the rotation drive 25) and buttons to control the lifting and lowering of the punching rod 200 (i.e., the movement of the telescopic drive 23). By setting up the controller 50, the operator can control the movement of the gantry frame 10, the punching mechanism 20, and the punching rod 200 from one side of the cutting platform 60, improving the convenience of the punching operation.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
