Description

Technical Field

[0001] This utility model relates to the field of denim processing technology, and in particular to a device for distressing and polishing denim holes. Background Technology

[0002] Denim is a relatively thick, yarn-dyed twill cotton fabric. The warp yarns are dark, usually indigo, while the weft yarns are light, usually light gray or bleached off-white yarn. It is also known as indigo workwear. When making denim clothing, the fabric is usually distressed. The distressing is done by sanding, and the warp or weft yarns are usually preserved, or even completely torn.

[0003] Existing sanding devices are not convenient for securing denim before sanding, usually requiring manual securing, which makes the operation cumbersome. Furthermore, when changing the sanding direction, the fabric is usually rotated manually, which further increases the complexity of the operation and reduces work efficiency. Utility Model Content

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-2 A denim distressing device includes a worktable 1, a first moving component 3 mounted on the worktable 1 via a bracket 2 for adjusting the position of a distressing machine 6 along the x-axis, a second moving component 4 mounted on the first moving component 3 for adjusting the position of the distressing machine 6 along the y-axis, a third moving component 5 mounted on the second moving component 4 for adjusting the position of the distressing machine 6 along the z-axis, a distressing machine 6 mounted on the third moving component 5, and a positioning adjustment mechanism mounted on the worktable 1. Its distinguishing feature is that:

[0024] The positioning adjustment mechanism includes an angle adjustment component 7, a cylinder 8, a pressure application part 9, and a placement platform 10. The placement platform 10 is mounted on the angle adjustment component 7, and its angle is controlled by the angle adjustment component 7. There are four cylinders 8, which are respectively distributed on the four sides of the placement platform 10. The pressure application part 9 is installed at the output end of the cylinder 8.

[0025] The angle adjustment assembly 7 includes a chassis 701, a gear seat 702, a guide rail 703, a rack 704, and an electric push rod 705. The gear seat 702 is rotatably mounted on the top of the chassis 701. The rack 704 is meshed with the gear seat 702 and slides along the guide rail 703. The output end of the electric push rod 705 is fixedly connected to one end of the rack 704.

[0026] The denim fabric is placed flat on the placement table 10, with its four sides hanging down at the four sides of the placement table 10. Then, the drive cylinder 8 pushes the pressure unit 9 to move towards the groove 1001. The pressure unit 9 clamps the denim fabric at the groove 1001. Then, the drive 3 adjusts the position of the second moving component 4 (that is, adjusts the position of the sanding machine 6 in the x-axis direction). The drive 4 adjusts the position of the third moving component 5 (adjusts the position of the sanding machine 6 in the y-axis direction). Then, the drive 5 adjusts the position of the sanding machine 6 in the z-axis direction, so that the third moving component 5 contacts the denim fabric, thereby sanding the denim fabric in the weft direction through the third moving component 5.

[0027] When the denim warp is sanded as needed, the electric push rod 705 can be driven to push the rack 704 to move along the guide rail 703. The rack 704 synchronously drives the tooth seat 702 to rotate until the placement table 10 rotates ninety degrees. The denim is then positioned again through the pressure part 9, and the sanding machine 6 can be controlled to sand the denim warp.

[0028] The device can easily fix the denim fabric before sanding without manual operation or additional fixing mechanisms. It can also easily switch the sanding direction of the denim fabric, and can still fix the fabric after switching. The operation process is simple and efficient.

[0029] The first moving component 3, the second moving component 4, and the third moving component 5 each include a motor, a lead screw, a guide rail, and a slide. The lead screw is fixedly connected to the output end of the motor, and the slide is driven by the lead screw and slides along the guide rail. The second moving component 4 is horizontally mounted on the slide of the first moving component 3, and the third moving component 5 is vertically mounted on the slide of the second moving component 4. The sander 6 is mounted on the slide of the third moving component 5. The sander 6 can be moved to the position where holes need to be sanded in the denim fabric through the first moving component 3, the second moving component 4, and the third moving component 5. It can be rotated in conjunction with the placement table 10 through the angle adjustment component 7 to sand the warp and weft threads of the denim fabric, making it highly adaptable.

[0030] The placement platform 10 has slots 1001 on all four sides, and the slots 1001 are chamfered. With the slots 1001 provided, after the cylinder 8 drives the pressure unit 9 to move, the pressure unit 9 can apply pressure and clamp the denim fabric at the slots 1001. After limiting the four sides of the denim fabric, the denim fabric can be stably sanded.

[0031] Multiple evenly arranged protruding teeth are provided on one side of the pressure part 9, and the protruding teeth are arranged in a trapezoidal structure; the length of the pressure part 9 is less than the width of the placement table 10; the pressure part 9 is provided with protruding teeth so that the pressure part 9 can apply stable pressure to the denim fabric, and restrict the four sides of the denim fabric at the groove 1001, so as to facilitate the subsequent sanding treatment of the denim fabric by the sanding machine 6.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
