DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will combine the drawings and specific embodiments to elaborate on the utility model in detail.

[0022] Embodiment: Please refer to Figures 1 to 5, this embodiment provides a device for aligning patterns and stripes in fabric cutting, including a workbench 1. The top surface of the workbench 1 is embedded with a laying table 2 for placing the fabric. Thread nails are inserted through the laying table 2. The laying table 2 is made of a flexible material, such as smooth rubber material, to facilitate the insertion of the subsequent thread nails. On the bottom surface of the workbench 1, there are symmetrically arranged legs 20 on the left and right for supporting the workbench 1 to stand on the ground. On the top surface of the workbench 1, there are symmetrically arranged support frames 3 on the left and right. Above the two support frames 3, there is a horizontally arranged mounting frame 4. The bottom surface of the mounting frame 4 is fixedly connected to the top of the two support frames 3. An installation groove 5 is inwardly opened on the bottom wall of the mounting frame 4, and the installation groove 5 is arranged along the length direction of the mounting frame 4 within the mounting frame 4. A lead screw 6 is rotatably connected in the installation groove 5. An installation block 7 is slidably connected to the lead screw 6 and a lead screw nut 8 is threadedly connected to the lead screw 6. The installation block 7 is fixedly connected to the lead screw nut 8, so that when the lead screw nut 8 moves, it can drive the installation block 7 to move accordingly. A laser lamp 9 is provided at the bottom of the installation block 7. The laser emission end of the laser lamp 9 is oriented towards the laying table 2. The laser lamp 9 can emit a cutting positioning beam. When the cutting positioning beam emitted by the laser lamp 9 irradiates the fabric on the laying table 2, an appropriate cutting line can be formed on the fabric, and this cutting line can be used as a reference line for subsequent cutting. The shape of the cutting line formed by the laser lamp 9 on the fabric can be determined according to the actual situation. The laser lamp 9 can be replaced by a cutting lamp of the brand Tengtuo Machinery and model One-word Cross in the existing technology. A driving motor 10 is provided on the right side wall of the mounting frame 4. The electric spindle of the driving motor 10 is fixedly connected to the lead screw 6, so that when the driving motor 10 starts to work, it can drive the lead screw 6 to rotate accordingly.

[0023] Through the foregoing settings, when the fabric needs to be cut, the fabric is laid flat on the laying table 2. Then, by turning on the laser lamp 9, the cutting positioning beam emitted by the laser lamp 9 will form an appropriate cutting line on the fabric, which can be used as a reference line for cutting, facilitating the staff to draw a straight and smooth cutting line. The staff can pass thread nails through the fabric, and the thread nails pass through the fabric and are nailed into the laying table 2, which can not only fix the fabric but also play a guiding role, facilitating the drawing of the cutting line. After that, the staff can cut and sew the fabric according to the drawn cutting line. After sewing is completed, by removing the thread nails, the sewn fabric can be taken off the laying table 2. At the same time, the staff can control the driving motor 10 to start working. After the driving motor 10 works, it can drive the lead screw 6 to rotate. After the lead screw 6 rotates, the lead screw nut 8 can move along the lead screw 6 accordingly to drive the installation block 7 to move, so as to adjust the position of the laser lamp 9 and thus adjust the position of the cutting line formed on the fabric to meet different cutting requirements.

[0024] The quantity and distribution of the laser lamps 9 can be determined according to actual needs. In this embodiment, the number of the laser lamps 9 is two, and they are symmetrically arranged in the installation groove 5. Correspondingly, the number of the installation blocks 7 and the lead screw nuts 8 is also two to adapt to the number of the laser lamps 9. The screwing directions of the two lead screw nuts 8 with the lead screw 6 are set in the opposite direction, so that when the lead screw 6 rotates, the two lead screw nuts 8 can move in opposite directions, thereby enabling an appropriate adjustment of the distance between the two laser lamps 9 to adapt to clothing with different size requirements to be cut out.

[0025] To facilitate the fixation of the fabric and ensure the flatness of the fabric placed on the laying table 2, a limiting component 11 for limiting the fabric is arranged on the workbench 1. The limiting component 11 is arranged at each vertex position of the workbench 1. The limiting component 11 includes a first mounting plate 12 which is arranged on the workbench 1. A first fixing plate 13 is arranged on the first mounting plate 12. A first adjusting screw 14 is threadedly connected to the first fixing plate 13. The first adjusting screw 14 is vertically arranged through the first fixing plate 13. A first turning handle 15 is arranged at the top of the first adjusting screw 14. A limiting block 16 is rotatably connected to the bottom of the first adjusting screw 14. The limiting block 16 is made of a flexible material, such as rubber material, to avoid damaging the fabric when the fabric is subsequently pressed. The limiting block 16 in each limiting component 11 is located above the corresponding vertex position of the laying table 2. A second fixing plate 17 is also fixedly arranged on the workbench 1. The limiting component 11 further includes the second fixing plate 17 which is fixedly arranged on the workbench 1. A second adjusting screw 18 is threadedly connected to the second fixing plate 17. The second adjusting screw 18 is horizontally arranged through the second fixing plate 17. One end of the second adjusting screw 18 is rotatably connected to the first mounting plate 12. The bottom of the first mounting plate 12 does not contact the workbench 1. The first mounting plate 12 is indirectly connected to the workbench 1 through the connection with the second adjusting screw 18. A second turning handle 19 is arranged at the other end of the second adjusting screw 18. At the same time, each second fixing plate 17 is obliquely arranged on the workbench 1. The inclined angle between each second fixing plate 17 and the corresponding side of the laying table 2 is 45°. The included angle between each second adjusting screw 18 and the corresponding second fixing plate 17 is 90°. The midpoint of each limiting block 16 and the center line of the corresponding second adjusting screw 18 are arranged on the same horizontal line.

[0026] With the above settings, when the fabric is laid flat on the laying table 2, by placing the four corners of the fabric under the limiting blocks 16 at corresponding positions, and then, by using the first turning handle 15 to rotate the first adjusting screw 14, the limiting blocks 16 move downward, thereby pressing the four corners of the fabric. After that, by using the second turning handle 19 to rotate the second adjusting screw 18, the second adjusting screw 18 moves away from the laying table 2, so that the second adjusting screw 18 can drive the first mounting plate 12 to move, thereby driving the first fixing plate 13, the first adjusting screw 14 and the limiting blocks 16 to move, so as to pull the whole fabric flat by pulling the four corners of the fabric, thereby ensuring the flatness of the fabric on the laying table 2 and facilitating the subsequent cutting work.

[0027] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
