Description

Technical Field

[0001] This application relates to the field of fabric edge cutting technology, and in particular to a laser edge cutting device for printed fabrics. Background Technology

[0002] Printed fabric is a product in which patterns or text are printed onto the fabric using a special printing process. This process gives the fabric rich visual effects and personalized designs, and it is widely used in clothing, home furnishings, and other fields. During the production of printed fabric, the edges of both sides need to be trimmed to meet the different width requirements of various customers.

[0003] Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating the material to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf, thus completing the cutting of the material.

[0004] Traditional edge trimming methods typically use a blade to trim the fabric edges. Due to the inherent structural characteristics of the fabric, edges cut with a blade are prone to fraying, forming rough edges that affect the fabric's appearance, reduce durability and processing performance, and require separate treatment, significantly reducing overall production efficiency. Later, laser cutting was adopted for fabric edge trimming. However, during laser cutting, the laser power, cutting speed, and fabric material all contribute to the release of incompletely vaporized microparticles as debris. These fabric debris scattered in the air can affect the workshop environment and pose a potential threat to workers' health. If debris remains on the cut surface of the fabric, it can also affect the overall aesthetics of the product.

[0005] However, existing laser edge-cutting equipment for fabrics lacks a device for handling the aforementioned fabric debris. For example, utility model patent application number 202420002024.X—a fabric cutting device—includes a fabric cutting workbench, a support frame fixedly connected to the upper end face of the workbench, a servo second motor fixedly connected to the right side face of the support frame, a groove opened on the lower end face of the support frame, a reciprocating lead screw rotatably connected in the groove, a limit block threadedly connected to the surface of the reciprocating lead screw, a first telescopic cylinder fixedly connected to the center of the lower end face of the limit block, a connecting plate fixedly connected to the telescopic end of the first telescopic cylinder, a second telescopic cylinder fixedly connected to the upper end face of the fabric cutting workbench, a laser cutter fixedly connected to the lower end face of the connecting plate, and a heating edge-sealing block fixedly connected to the lower end face of the connecting plate.

[0028] like Figures 1-4 As shown, a laser cutting device for printed fabrics includes a worktable 1, a laser cutting device 2 mounted on top of the worktable 1, and a fixedly connected mounting plate 3. A cavity 4 is provided in the middle of the mounting plate 3. The mounting plate 3 is connected to a horizontal adjustment structure 5 and a vertical adjustment structure 6. The horizontal adjustment structure 5 is connected to the mounting plate 3, one end of the vertical adjustment structure 6 is fixedly connected to the horizontal adjustment structure 5, and the other end of the vertical adjustment structure 6 is connected to the laser cutting device 2. An air jet device 7 is provided on one side of the mounting plate 3. The air jet device 7 includes a nitrogen cylinder 71, an output pipe 72, and a high-pressure nozzle 73.

The suction hood 83 is located on the other side of the laser cutting device 2 and is connected to the suction pipe 82, which in turn is connected to the dust collector 81. By setting up an air jet device 7 and a dust collection device 8, the dust collection device 8 can efficiently and promptly adsorb tiny debris that is not completely vaporized when the laser cutting device 2 cuts the fabric 25, significantly reducing the suspended concentration of fabric debris in the air, effectively improving the environmental hygiene conditions of the operating area, and reducing the safety and health risks faced by operators due to inhaling such dust. The air jet device 7 can blow up debris that is electrostatically adhered to the cut fabric, and the blown debris will be promptly adsorbed and cleaned by the dust collection device 8, improving the cleanliness and aesthetics of the fabric surface after cutting, reducing the impact of debris residue on subsequent processing steps, and improving the overall processing quality.

[0029] It should be noted that support frames 9 are provided on both sides of the workbench 1. The upper end face of the support frame 9 is fixedly connected to the lower end face of the mounting plate 3. A slide rod 10 is fixedly installed in the cavity 4 of the mounting plate 3.

[0030] Furthermore, the lateral adjustment structure 5 includes a first cylinder 51 and a first connecting plate 52. The first connecting plate 52 is slidably connected to the slide rod 10, and the first connecting plate 52 is fixedly connected to the output end of the first cylinder 51.

[0031] It should be noted that the vertical adjustment structure 6 includes a second cylinder 61 and a second connecting plate 62. The upper end of the second connecting plate 62 is fixedly connected to the output end of the second cylinder 61, the second cylinder 61 is fixedly connected to the first connecting plate 52, and the lower end of the second connecting plate 62 is fixedly connected to the laser cutting device 2.

[0032] Furthermore, a pressure plate 16 with the laser cutting device 2 as the axis of symmetry is fixedly provided on the lower end face of the second connecting plate 62; the main purpose of this structure is to gently press the fabric against the rotating roller 11, so that the laser cutting device 2 can cut the fabric, prevent the fabric from moving during the cutting process, and ensure the accuracy and consistency of the cutting.

[0033] It should be noted that fixed plates 17 are also fixedly installed on both sides of the workbench 1. A second motor 18 is fixedly installed on one side of the fixed plate 17. A screw 19 is rotatably installed between the two fixed plates 17. One end of the screw 19 passes through the fixed plate 17 and is fixedly connected to the output end of the second motor 18.

[0034] It should be noted that a rotating roller 11 is rotatably arranged between the two support frames 9. One end of the rotating roller 11 is fixedly connected to a synchronous pulley A12. A first motor 15 is arranged below the worktable 1. A reducer is fixedly connected to the output end of the first motor 15. A synchronous pulley B13 is fixedly connected to the output end of the reducer. A synchronous belt 14 is arranged between the synchronous pulley B13 and the synchronous pulley A12. This structure is mainly used for conveying fabric.

[0035] The working principle and process of this utility model are as follows:

[0036] The first motor 15 is started, and it transmits power to the synchronous pulley B13 via a reducer. The synchronous pulley B13 then transmits the power to the synchronous pulley A12 via the synchronous belt 14. The synchronous pulley A12 drives the rotating roller 11 to rotate, and the rotation of the rotating roller 11 drives the movement of the printed fabric. The first cylinder 51 is started, and it drives the two first connecting plates 52 to move in opposite directions along the slide bar 10. The movement of the first connecting plates 52 drives the second cylinder 61, the second connecting plates 62, the laser cutting device 2, and the pressure plate 16 to move in opposite directions together until the laser cutting device 2 reaches the preset value of the fabric cutting width. Then, the second cylinder 61 is started, and it drives the second connecting plate 62, the laser cutting device 2, and the pressure plate 16 to move downwards until the pressure plate 16 gently presses the printed fabric against the rotating roller 11. The cutting device 2 is activated to begin cutting the printed fabric passing below. Simultaneously, the vacuum cleaner 81 is turned on, and the vacuum hood 83 absorbs the fabric debris generated by the laser cutting device 2 during the cutting of the printed fabric, sending it into the vacuum cleaner 81 for processing through the vacuum pipe 82. During the process of the first cylinder 51 starting and driving the first connecting plate 52, the second motor 18 is activated, driving the screw 19 to rotate. The rotation of the screw 19 will drive the two movable blocks 20 to move in opposite directions along the screw 19. The movement of the movable blocks 20 will cause the nitrogen cylinder 71 above to move as well. The movement of the nitrogen cylinder 71 will cause the output pipe 72 and the high-pressure nozzle 73 to move. When the laser cutting device 2 is working, the high-pressure nozzle 73 will spray air at the cutting edge of the printed fabric, blowing the debris adhering to the fabric toward the vacuum hood 83 in a timely manner.
