Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothing processing, and specifically relates to a laser marking machine for clothing processing. BACKGROUND

[0002] In the modern clothing processing industry, laser marking machines are widely used in the pattern and logo processing of clothing materials such as cloth and leather due to their high marking precision, fast efficiency and flexible pattern customization. However, the existing laser marking machines for clothing processing still have many drawbacks in actual use. 1. The unwinding and winding mechanism of the traditional laser marking machine lacks an effective auxiliary feeding device. The cloth needs to be manually pulled from the unwinding roller to the winding roller and fixed, which not only increases the labor intensity of the workers, but also takes a long time to feed, seriously affecting the overall processing efficiency. 2. Clothing materials are soft and prone to wrinkling. The existing equipment cannot quickly and automatically flatten the cloth before marking. Some equipment uses hydraulic cylinders to pull the cloth with clamping clamps, which can easily damage the edges of the cloth and cause stretching and deformation, affecting product quality. Manual flattening is inconsistent and can cause the marking pattern to shift or blur.

[0003] Therefore, the present application provides a laser marking machine for clothing processing, which can eliminate the drawbacks of the existing device. SUMMARY

A rotating shaft is fixedly connected to one end of the adsorption roller, and a rotating cylinder is fixedly connected to the other end. Both the rotating shaft and the rotating cylinder are connected to the installation block through bearings. Several air holes are opened on the periphery of the adsorption roller. An air pipe is rotatably connected to the rotating cylinder, and the rotating cylinder is connected to an external negative pressure generator through the air pipe. The side wall of the placement box is provided with a guide rail four, and a slider three is slidably connected to the inner wall of the guide rail four. A rack frame is fixedly connected to the slider three, and a gear is fixedly connected to the rotating shaft. Two racks are provided in the rack frame, and the two racks are located on both sides of the rack frame. The two gears mesh with the two racks of the rack frame respectively. A push rod is fixedly connected to the side wall of the rack frame. An abutting horizontal plate is installed on the side wall of the processing seat. The abutting horizontal plate is provided with an inclined surface. The push rod passes through the placement box and abuts against the abutting horizontal plate.

[0007] In one alternative: the lower positioning block has two opposing sliders four fixedly connected to its side wall, and the placement box has four opposing guide rails three on its side wall, with the sliders four slidably connected to the inner walls of the guide rails three.

[0008] In one alternative: the push rod is fixedly connected to a retaining ring, and a spring is fixedly connected between the retaining ring and the side wall of the placement box.

[0009] In one alternative: the side wall of the placement box is connected to a bidirectional screw rod II via a bearing, and the bidirectional screw rod II is threadedly connected to two lower positioning blocks.

[0010] In one alternative embodiment: the pressing and positioning module includes a second slider, an upper positioning block, and a lifting plate. The side wall of the placement box has two symmetrical guide rails, the inner wall of the guide rails is slidably connected to the second slider, the bottom wall of the second slider is fixedly connected to two symmetrical guide rails, the inner walls of the two guide rails are slidably connected to limit sleeves, the two limit sleeves are fixedly connected to the lifting plate, the bottom wall of the lifting plate is connected to the upper positioning block through a telescopic rod, and a spring is fixedly connected between the lifting plate and the upper positioning block. A lifting rod is slidably connected through the side wall of the placement box. The lifting rod is fixedly connected to a limit block. The lifting rod is slidably connected through two limit sleeves. A guide rail is installed on the side wall of the processing seat. The lifting rod is slidably connected to the inner wall of the guide rail. Inclined tracks are provided at both ends of the guide rail.

[0011] In one alternative embodiment, the upper and lower positioning blocks each have toothed grooves on their opposite surfaces.

[0012] In one alternative: a fixing plate is fixedly connected to the side wall of the placement box, and a spring is fixedly connected between the limiting block and the fixing plate.

[0013] In one alternative: the placement box is connected to a bidirectional screw via a bearing, the bidirectional screw is threadedly connected to two sliders, the mounting block and the bidirectional screw are connected by a sprocket and chain drive, and a rotating handle is provided at one end of the bidirectional screw.

[0014] In one alternative: a limiting roller is rotatably mounted on the side wall of the processing seat; two lifting blocks are slidably connected through the side wall of the processing seat; lifting rollers are rotatably connected to the lifting blocks; two lifting motors are mounted on the side wall of the processing seat; the output end of the lifting motors is connected to the lifting blocks; and a processing table is placed on the bottom wall of the processing seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides an auxiliary feeding assembly consisting of a slider, a placement box, and a threaded rod. Workers only need to place one end of the fabric through the perforation into the placement box, and the threaded rod driven by the motor will move the placement box to automatically pull the fabric to the take-up roller position. This eliminates the need for manual long-distance pulling and fixing, significantly reducing the labor intensity of workers, shortening the feeding time, and effectively improving the overall efficiency of mass production.

[0016] The flattening module of this invention employs a negative pressure adsorption roller combined with a gear and rack transmission structure. An external negative pressure generator causes the adsorption rollers to adsorb the fabric surface. Simultaneously, during the movement of the placement box, the push rod engages with the inclined surface of the contact plate, driving the two adsorption rollers to rotate in opposite directions, uniformly stretching both ends of the fabric to achieve automatic flattening. Compared to traditional clamping and pulling methods, the flattening method combining negative pressure adsorption and roller rotation is gentler, avoiding fabric damage and stretching deformation, and providing high flatness consistency, thus ensuring high-precision marking later.

[0017] The pressing and positioning module of this invention works in conjunction with the leveling module. While the adsorption roller levels the fabric, the lifting rod automatically descends along the inclined track of guide rail one, driving the upper positioning block to press down and cooperate with the lower positioning block to achieve precise fixing of the fabric. The toothed grooves on the opposing surfaces of the upper and lower positioning blocks increase the contact pressure, further improving the fixing stability and preventing the fabric from shifting or loosening during marking. Moreover, the positioning process requires no manual intervention, has a high degree of automation, and effectively ensures the consistency and accuracy of the pattern during continuous marking.

[0018] This invention utilizes the linkage design of bidirectional screw one, bidirectional screw two, and sprocket and chain drive components. By rotating the handle, the distance between the upper and lower positioning blocks can be adjusted synchronously, quickly adapting to fabrics of different widths. At the same time, the upper positioning block is connected to a spring via a telescopic rod, providing a certain buffer adjustment space to adapt to clothing fabrics of different thicknesses. This eliminates the need to replace specialized mechanisms, expanding the applicability of the equipment and reducing the equipment investment for different products. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-9 As shown, a laser marking machine for garment processing includes a processing base 1, a planar mover 4, a laser emitter 10, and an auxiliary feeding assembly 11. The processing base 1 has an unwinding roller 2 and a rewinding roller 3 driven by an independent motor and a hydraulic cylinder installed on its side wall. The processing base 1 also has a planar mover 4 installed on its side wall to drive the laser emitter 10 to move horizontally. The planar mover 4 is used to laser mark the fabric. The processing base 1 has a through hole 18 for placing one end of the fabric. An auxiliary feeding assembly 11 is installed on the side wall of the processing base 1 to feed the fabric roll on the unwinding roller 2 to the position of the winding roller 3. The auxiliary feeding assembly 11 includes a slider 14 and a placement box 16. The slider 14 is fixedly connected to the side wall of the placement box 16. The slider 14 is slidably connected to the processing base 1. A threaded rod 15 is installed on the side wall of the processing base 1. The threaded rod 15 is driven to rotate by a motor. The threaded rod 15 is threadedly connected to the slider 14. The placement box 16 is equipped with a pressing and positioning module and a flattening module; The pressing and positioning module is used to fix the fabric placed in the placement box 16; The leveling module is used to automatically level the fabric placed in the placement box 16.

[0031] The fabric of the garment is placed on the unwinding roller 2. The hydraulic cylinder that drives the unwinding roller 2 to expand and contract is activated by the controller to fix and support the fabric. The worker then passes one end of the fabric through the perforation 18 and drapes it on the placement box 16. The motor that drives the unwinding roller 2 to rotate and the motor that drives the threaded rod 15 to rotate are activated, so that the placement box 16 moves the fabric towards the take-up roller 3. The worker does not need to pull one end of the fabric to the position of the take-up roller 3, which reduces the workload of the worker and is more efficient and convenient. The worker only needs to place one end of the fabric in the placement box 16.

[0032] In one embodiment, the leveling module includes an adsorption roller 22 and a lower positioning block 23. Two symmetrical lower positioning blocks 23 are slidably connected to the bottom wall of the placement box 16. An installation block 31 is fixedly connected to the side wall of the lower positioning block 23. A rotating shaft 35 is fixedly connected to one end of the adsorption roller 22, and a rotating cylinder 37 is fixedly connected to the other end. Both the rotating shaft 35 and the rotating cylinder 37 are connected to the installation block 31 through bearings. Several air holes are opened on the periphery of the adsorption roller 22. An air pipe is rotatably connected to the rotating cylinder 37. The rotating cylinder 37 is connected to an external negative pressure generator through the air pipe. The side wall of the placement box 16 is provided with a guide rail 20. The inner wall of the guide rail 20 is slidably connected to a slider 26. The slider 26 is fixedly connected to a rack frame 24. The rotating shaft 35 is fixedly connected to a gear 36. Two racks are provided in the rack frame 24. The two racks are located on both sides of the rack frame 24. The two gears 36 mesh with the two racks of the rack frame 24 respectively. A push rod 32 is fixedly connected to the side wall of the rack frame 24. The side wall of the processing seat 1 is equipped with an abutting horizontal plate 13. The abutting horizontal plate 13 is provided with an inclined surface. The push rod 32 passes through the placement box 16 and abuts against the abutting horizontal plate 13.

[0033] As the placement box 16 moves toward the take-up roller 3, the external negative pressure generator is activated, causing a negative pressure to be generated inside the adsorption roller 22. The adsorption roller 22 adsorbs the fabric onto the surface. At the same time, the push rod 32 abuts against the inclined surface of the abutting plate 13. As the placement box 16 moves, the push rod 32 is pushed into the placement box 16. At this time, the rack frame 24 drives the two gears 36 to rotate in opposite directions, causing the two adsorption rollers 22 to rotate in opposite directions. Since there is a negative pressure inside the adsorption roller 22, the two ends of the fabric are adsorbed and pulled, thus achieving automatic flattening of the fabric. The negative pressure adsorption combined with the adsorption roller 22 flattens the fabric, which is less likely to damage the fabric compared to the traditional hydraulic cylinder and clamping clamp for pulling and flattening.

[0034] In one embodiment, the lower positioning block 23 has two opposing sliders 40 fixedly connected to its side wall, and the placement box 16 has four opposing guide rails 19 on its side wall. The sliders 40 are slidably connected to the inner walls of the guide rails 19, providing sliding limit for the lower positioning block 23.

[0035] In one embodiment, the push rod 32 is fixedly connected to a retaining ring 33, and a spring is fixedly connected between the retaining ring 33 and the side wall of the placement box 16.

[0036] The spring drives the push rod 32 to reset.

[0037] In one embodiment, the side wall of the placement box 16 is connected to a bidirectional screw 30 via a bearing, and the bidirectional screw 30 is threadedly connected to two lower positioning blocks 23.

[0038] The distance between the two lower positioning blocks 23 can be adjusted by rotating the bidirectional screw 30.

[0039] In one embodiment, the pressing and positioning module includes a second slider 21, an upper positioning block 25, and a lifting plate 42. Two symmetrical guide rails 17 are provided on the side wall of the placement box 16. The second slider 21 is slidably connected to the inner wall of the guide rails 17. Two symmetrical guide rails 43 are fixedly connected to the bottom wall of the second slider 21. Limiting sleeves 44 are slidably connected to the inner walls of the two guide rails 43. A lifting plate 42 is fixedly connected between the two limiting sleeves 44. The upper positioning block 25 is connected to the bottom wall of the lifting plate 42 through a lifting rod 41. A spring is fixedly connected between the lifting plate 42 and the upper positioning block 25. A lifting rod 27 is slidably connected through the side wall of the placement box 16. The lifting rod 27 is fixedly connected to a limit block 28. The lifting rod 27 is slidably connected through the two limit sleeves 44. A guide rail 12 is installed on the side wall of the processing seat 1. The lifting rod 27 is slidably connected to the inner wall of the guide rail 12. Inclined tracks are provided at both ends of the guide rail 12.

[0040] As the adsorption roller 22 rotates, it feeds the fabric upwards to the lower positioning block 23. At the same time, the lifting rod 27, driven by the placement box 16, moves downwards along the inclined track of the guide rail 12. The lifting rod 27 drives the two limiting sleeves 44 to move downwards, and the two limiting sleeves 44 drive the lifting plate 42 to move downwards until the lifting rod 27 moves to the horizontal track of the guide rail 12. The lifting plate 42 then drives the upper positioning block 25 to move to the position of the lower positioning block 23 and fixes the straightened and flat fabric. This prevents the fabric from detaching from the placement box 16 during subsequent movement and ensures that the fabric remains in a stable and flat state.

[0041] In one embodiment, the upper positioning block 25 and the lower positioning block 23 are both provided with toothed grooves on their opposite surfaces.

[0042] The toothed grooves on the opposite surfaces of the lower positioning block 23 and the upper positioning block 25 can increase the pressure and improve the stability of fixing the fabric.

[0043] In one embodiment, a fixing plate 34 is fixedly connected to the side wall of the placement box 16, and a spring is fixedly connected between the limiting block 28 and the fixing plate 34.

[0044] In one embodiment, the placement box 16 is connected to a bidirectional screw 29 via a bearing. The bidirectional screw 29 is threadedly connected to two sliders 21. The mounting block 31 and the bidirectional screw 29 are connected by a sprocket and chain drive 38. One end of the bidirectional screw 29 is provided with a rotating handle 39.

[0045] This device can also be adjusted according to different widths of fabric. Before using the device, simply rotate the rotating handle 39 manually. Rotating the handle 39 will drive the bidirectional screw 29 to rotate. The bidirectional screw 29 will drive the bidirectional screw 30 to rotate synchronously through the sprocket and chain drive component 38. This can adjust the distance between the two upper positioning blocks 25 and the two lower positioning blocks 23 to adapt to different widths of fabric and improve the applicability of the device.

[0046] In one embodiment, a limiting roller 6 is rotatably installed on the side wall of the processing base 1, two lifting blocks 8 are slidably connected through the side wall of the processing base 1, and lifting rollers 7 are rotatably connected to the lifting blocks 8. Two lifting motors 9 are installed on the side wall of the processing base 1, and the output end of the lifting motors 9 is connected to the lifting blocks 8. A processing table 5 is placed on the bottom wall of the processing base 1.

[0047] Start the two lifting motors 9, which drive the lifting block 8 to descend. The lifting block 8 drives the lifting roller 7 to descend, so that the fabric is attached to the upper surface of the processing table 5. Then start the plane mover 4 to drive the laser emitter 10 to move horizontally and print the required pattern on the fabric. Then, the rotating motors of the unwinding roller 2 and the winding roller 3 are started to make the fabric move for continuous laser marking.

[0048] The above embodiments disclose a laser marking machine for garment processing, the specific working principle and process of which are as follows: S1: The fabric of the garment is placed on the unwinding roller 2. The hydraulic cylinder that drives the unwinding roller 2 to expand and contract is started by the controller to fix and support the fabric. The worker puts one end of the fabric through the perforation 18 and drapes it on the placement box 16. The motor that drives the unwinding roller 2 to rotate and the motor that drives the threaded rod 15 to rotate are started, so that the placement box 16 moves the fabric towards the take-up roller 3. The worker does not need to pull one end of the fabric to the position of the take-up roller 3, which reduces the workload of the worker and is more efficient and convenient. The worker only needs to drape one end of the fabric in the placement box 16. S2: While the placement box 16 moves toward the take-up roller 3, the external negative pressure generator is activated, which generates negative pressure inside the adsorption roller 22. The adsorption roller 22 adsorbs the fabric onto the surface. At the same time, the push rod 32 abuts against the inclined surface of the abutting plate 13. As the placement box 16 moves, the push rod 32 is pushed into the placement box 16. At this time, the rack frame 24 drives the two gears 36 to rotate in opposite directions, causing the two adsorption rollers 22 to rotate in opposite directions. Since there is negative pressure inside the adsorption rollers 22, the two ends of the fabric are adsorbed and pulled, thus achieving automatic flattening of the fabric. The negative pressure adsorption combined with the adsorption roller 22 flattens the fabric, which is less likely to damage the fabric compared to the traditional hydraulic cylinder and clamping clamp for pulling and flattening.

[0049] S3: When the adsorption roller 22 rotates, it will send the fabric up to the lower positioning block 23. At the same time, the lifting rod 27, driven by the placement box 16, moves down along the inclined track of the guide rail 12. The lifting rod 27 drives the two limiting sleeves 44 to move down, and the two limiting sleeves 44 drive the lifting plate 42 to move down until the lifting rod 27 moves to the horizontal track of the guide rail 12. The lifting plate 42 drives the upper positioning block 25 to move to the position of the lower positioning block 23 and fixes the straightened and flat fabric to prevent one end of the fabric from falling off the placement box 16 during the subsequent movement of the placement box 16, and also to keep the fabric in a stable and flat state. The inclined track position of guide rail 12 corresponds to the inclined surface position of one end of the horizontal plate 13, which can automatically and continuously realize the flattening of the fabric and the fixing after flattening.

[0050] S4: When the auxiliary feeding component 11 moves one end of the fabric close to the position of the take-up roller 3, but before it moves to the other end of the inclined track of the guide rail 12, the fabric is placed at the jaws of the take-up roller 3 and clamped by the clamping device of the take-up roller 3. This can be done manually or with the assistance of a robotic arm. After clamping, the auxiliary feeding component 11 continues to move a short distance towards the position of the take-up roller 3. At this time, the external negative pressure generator is turned off, and the lifting rod 27 rises under the drive of the inclined track of the guide rail 12. The lifting rod 27 drives the upper positioning block 25 to rise, releasing the fixation of the flat fabric. S5: Start the two lifting motors 9, the two lifting motors 9 drive the lifting block 8 to descend, the lifting block 8 drives the lifting roller 7 to descend, and put the fabric into contact with the upper surface of the processing table 5. Then start the plane mover 4 to drive the laser emitter 10 to move horizontally and print the required pattern on the fabric. Then, the rotating motors of the unwinding roller 2 and the winding roller 3 are started to make the fabric move for continuous laser marking; This device can also be adjusted according to different widths of fabric. Before using the device, simply rotate the rotating handle 39 manually. Rotating the handle 39 will drive the bidirectional screw 29 to rotate. The bidirectional screw 29 will drive the bidirectional screw 30 to rotate synchronously through the sprocket and chain drive 38. The distance between the two upper positioning blocks 25 and the two lower positioning blocks 23 can be adjusted at the same time to adapt to different widths of fabric and improve the applicability of the device. The upper positioning block 25 cooperates with the lifting rod 41 and the spring. The upper positioning block 25 has a certain range of motion and can be used to fix fabrics of different thicknesses in a suitable way. The toothed grooves on the opposite surfaces of the lower positioning block 23 and the upper positioning block 25 can increase the pressure and improve the stability of fixing the fabric.

[0051] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
