Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric cutting machine for garment production. Background Technology

[0002] A fabric cutting machine is a mechanical device specifically designed for cutting various fabrics. It is widely used in the production processes of industries such as clothing, home textiles, leather, and automotive interiors. The cutting machine mainly consists of a frame, on which a horizontal bar that can move back and forth is mounted, and on the horizontal bar, a movable cutter is installed.

[0003] During the fabric cutting process, wrinkles may occur. Wrinkles can cause the cutting line to deviate from the predetermined path, resulting in inaccurate cutting dimensions. This can then affect the smooth progress of subsequent sewing, splicing, and other processes, thereby impacting the cutting accuracy.

[0004] Chinese Patent Publication No. CN 216072440 U discloses a CNC fabric cutting machine, relating to the field of fabric processing technology. It includes a cutting table, a laser cutting head, and a flattening mechanism. Support legs are installed at the four corners of the cutting table, and multiple fixing mechanisms for securing the fabric are installed on the left and right sides above the cutting table. Forward and backward moving mechanisms are provided on both sides of the cutting table, and support plates are installed on the outer sides of the two forward and backward moving mechanisms. This invention utilizes the coordinated use of a first electric telescopic rod, a telescopic spring, a flattening roller, and a motor. The first electric telescopic rod drives the flattening roller downwards to contact the fabric. The motor drives the two flattening rollers to rotate in opposite directions, thereby stretching the fabric between the two rollers to make it flat. Simultaneously, the flattening rollers further secure the fabric. The telescopic springs buffer the vibrations generated during the movement of the flattening rollers, resulting in better fabric cutting. It can be seen that although existing technologies include flattening rollers, the pressing effect of the flattening rollers cannot be controlled for different fabrics, leading to poor cutting accuracy.

[0034] One embodiment of this utility model provides a fabric cutting machine for garment production, comprising:

[0035] Rack 1;

[0036] The cutting section is located on the upper part of the frame 1 and includes a first slide rail 21, a second slide rail 22, a first crossbeam 23, and a cutting device 24. The first slide rail 21 is located on one side of the frame 1, the second slide rail 22 is located on the side of the frame 1 away from the first slide rail 21, one end of the first crossbeam 23 is slidably connected to the first slide rail 21, the other end of the first crossbeam 23 is slidably connected to the second slide rail 22, and the cutting device 24 is slidably connected to the first crossbeam 23.

[0039] The chassis 5 is located below the conveyor section and has a hollow structure. The main power supply is installed inside the chassis 5, and the frame 1 is mounted on the chassis 5.

[0040] Specifically, the cutting device 24 includes a mounting plate 241, a cutting tool 242, a positioning camera 243, a laser marker 244, a first universal wheel 245, and a second universal wheel 246. The mounting plate 241 is sleeved on the first crossbeam 23. The first universal wheel 245 is disposed on the bottom surface of the mounting plate 241. The second universal wheel 246 is symmetrically disposed with respect to the first universal wheel 245.

The positioning camera 243 is disposed between the cutting tool 242 and the second universal wheel 246. The laser marker 244 is disposed between the positioning camera 243 and the second universal wheel 246.

[0041] In this embodiment, the cutting device 24 is disposed between the first flattening roller 451 and the second flattening roller 452. The placement of the cutting device 24 between the flattening rollers ensures that the fabric has undergone sufficient flattening treatment before cutting, thereby reducing the impact of wrinkles on cutting accuracy.

[0042] In this embodiment, an electrical control box is also provided inside the chassis 5, which is used to control the cutting device 24 and control the machine.

[0043] In this embodiment, the cutting tool 242 is a milling cutter;

[0044] The positioning camera 243 captures image information on the fabric and monitors in real time whether the fabric may be slightly stretched or deformed due to factors such as tension and friction. Through the coordinated work of the electrical control box, it automatically tracks and compensates for the movement path of the cutter 242 to ensure the consistency of the cutting results.

[0045] The laser marker 244 emits a high-brightness laser line, which serves as a reference line for the movement of the cutter 242, thereby ensuring the accuracy of the cut.

[0046] Specifically, the leveling device includes a first leveling roller 451, a second leveling roller 452, a plurality of connecting rods, a plurality of bolts 454, a plurality of springs 455, and a plurality of sleeves 456; the first leveling roller 451 and the second leveling roller 452 are symmetrically arranged, each end of the first leveling roller 451 and the second leveling roller 452 is perpendicularly connected to a plurality of the connecting rods, the other end of the plurality of connecting rods is connected to a plurality of the springs 455, the end of each spring 455 away from the connecting rod is connected to a plurality of the bolts 454, the end of each bolt 454 away from the spring 455 is threadedly connected to a sleeve 456, and the sidewalls of the plurality of sleeves 456 are connected to a plurality of support rods of the leveling frame 44.

[0047] In this embodiment, before the fabric cutting machine starts working, the bolt 454 is tightened to apply a preload to the spring 455. During the operation of the fabric cutting machine, if the fabric thickness increases, the spring 455 automatically compresses, increasing the gap between the first leveling roller 451 and the second leveling roller 452 and the fabric respectively. If the fabric thickness decreases, the spring 455 automatically extends, reducing the gap between the first leveling roller 451 and the second leveling roller 452 and the fabric respectively. This eliminates the influence of changes in fabric thickness on the flattening pressure of the fabric.

[0048] Specifically, the connecting rods include a first connecting rod 453, a second connecting rod 457, a third connecting rod 458, and a fourth connecting rod 459; the first connecting rod 453 is connected to one end of the first leveling roller 451 via a bearing, the second connecting rod 457 is connected to the other end of the first leveling roller 451 via a bearing, the third connecting rod 458 is connected to one end of the second leveling roller 452 via a bearing, and the fourth connecting rod 459 is connected to the other end of the second leveling roller 452 via a bearing.

[0049] Specifically, the outer surfaces of the first leveling roller 451 and the second leveling roller 452 are both covered with anti-slip rubber.

[0050] Specifically, a cooling fan 51 is provided on the side wall of the chassis 5.

[0051] Specifically, the conveyor belt 31 is made of felt.

[0052] The working process of this utility model is as follows: the cutting machine is started, the conveying part starts to work, the first drive shaft 32 and the second drive shaft 33 drive the conveyor belt 31 to move, thereby conveying the fabric; when the fabric passes through the flattening part, the spring 455 automatically adjusts the gap between the first flattening roller 451 and the second flattening roller 452 and the fabric according to the actual thickness of the fabric, to ensure that the fabric is flat and wrinkle-free; when the cutting device 24 starts to work, the industrial camera monitors the image information of the fabric in real time, and the laser marker 244 emits a high-brightness laser line as a reference line for the movement of the cutter 242. When the first universal wheel 245 and the second universal wheel 246 support the mounting plate 241 and the cutter 242, the cutter 242 cuts the fabric by applying pressure.

[0053] For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
