Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an automatic fabric cutting device. Background Technology

[0002] Fabrics need to be cut when they are put into sewing production. Currently, three-axis cutting is used, which drives the cutting head to cut. However, because the fabric cannot be positioned, it is prone to wrinkles, resulting in poor cutting effect. Therefore, it is very important to obtain an automatic cutting device for textile fabrics that overcomes the above defects. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic fabric cutting device, comprising:

[0004] The work platform is equipped with at least one fabric laying area;

[0005] A three-axis moving platform, with a laser cutting head fixed on the Z-axis slider;

[0006] A fabric positioning assembly is disposed around the fabric laying area, comprising two upright blocks, a rotating shaft rotatably connecting the two upright blocks, a first torsion spring disposed between the two ends of the rotating shaft and the rotating groove opened on the upright blocks, a U-shaped rod fixed on the rotating shaft, a pressure cylinder sleeved on the U-shaped rod, and a second torsion spring cooperating between the pressure cylinder and the U-shaped rod.

[0007] The above technical solution improves the cutting effect, increases work efficiency, and reduces burrs by setting up the laser cutting head.

[0008] The first torsion spring can press the U-shaped rod down at least partially, thus increasing the positioning of the fabric. When the second torsion spring is put into use, the pressure cylinder rotates against the torque of the second torsion spring and then releases. Then, the pressure cylinder rotates counterclockwise, pulling the fabric outward to achieve the stretching and flattening of the fabric.

[0009] A silicone layer can be fixed on the surface of the pressure cylinder to increase the friction of contact.

[0010] A horizontal plate is also fixed to the Z-axis slider, and a pressure block is connected to the horizontal plate by a spring. The pressure block is located around the laser cutting head. A guide groove is opened upward at the bottom of the horizontal plate, and a guide post is fixed on the pressure block, which moves axially within the guide groove in at least part of its length. The spring is fixed between the bottom of the guide post and the bottom of the guide groove. Several ball bearings are rolledly connected to the bottom of the pressure block.

[0011] Through the above technical solution, the guide groove and guide post can ensure that the pressure block can only move up and down, and with the help of the ball bearings, it can help to hold down the fabric during cutting without affecting the three-axis movement of the laser cutting head.

[0012] Alternatively, the slider of the Z-axis may also have an air blowing channel and an air pulse generator connected to the air blowing channel via a pipe.

[0013] The air-blowing channel allows the fabric to be blown out before cutting, thus flattening it.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses an existing three-axis moving platform in conjunction with an existing laser cutting head to achieve a good edge cutting effect on the fabric. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0019] Referring to the accompanying drawings, this utility model adopts the following technical solution: an automatic fabric cutting device, comprising:

[0020] Work platform 1 is equipped with at least one fabric laying area;

[0021] The three-axis moving platform 2 has a laser cutting head 3 fixed on its Z-axis slider;

[0022] The fabric positioning component 4 is disposed around the fabric laying area and includes two upright blocks 5 fixed on the working platform 1. A rotating shaft 6 is rotatably connected between the two upright blocks 5. A first torsion spring 7 is disposed between the two ends of the rotating shaft 6 and the rotating groove opened on the upright block 5. A U-shaped rod 8 is fixed on the rotating shaft 6. A pressure cylinder 9 is sleeved on the U-shaped rod 8. A second torsion spring 10 is engaged between the pressure cylinder 9 and the U-shaped rod 8.

[0023] Through the above technical solution, the laser cutting head 3 is designed to improve the cutting effect, increase work efficiency, and reduce the generation of burrs.

[0024] The first torsion spring 7 is configured to at least partially press the U-shaped rod 8 downwards, increasing the positioning of the fabric; when the second torsion spring 10 is put into use, the pressure cylinder 9 rotates against the torque of the second torsion spring 10 and then releases, so that... Figure 1 As shown in the fabric positioning component 4 on the right, the pressure cylinder 9 rotates counterclockwise to pull the fabric to be cut outward, thereby stretching and laying the fabric flat.

[0025] A silicone layer can be fixed on the surface of the pressure cylinder 9 to increase the friction of contact.

[0026] A horizontal plate 11 is also fixed on the Z-axis slider. A pressure block 12 is connected to the horizontal plate 11 via a spring 15. The pressure block 12 is located around the laser cutting head 3. A guide groove 13 is formed at the bottom of the horizontal plate 11, and a guide post 14, which moves axially within the guide groove 13, is fixed on the pressure block 12. The spring 15 is fixed between the bottom of the guide post 14 and the bottom of the guide groove 13. Several ball bearings 16 are rolledly connected to the bottom of the pressure block 12.

[0027] Through the above technical solution, the guide groove 13 and guide post 14 can ensure that the pressure block 12 can only move up and down, and together with the ball bearing 16, it can help to press down the fabric during cutting without affecting the three-axis movement of the laser cutting head 3.

[0028] Alternatively, the slider of the Z-axis may also have an air blowing channel 17, and may also include an air pulse generator connected to the air blowing channel 17 via a pipe.

[0029] The air-blowing channel allows the fabric to be blown out before cutting, thus flattening it.
