Description
Technical Field
[0001] This invention relates to the field of garment production technology, and in particular to a garment fabric cutting device. Background Technology
[0002] Early garment production relied on manual cutting. The use of tools such as scissors and cutting knives was entirely dependent on the skills of the operators, which was not only inefficient but also made it difficult to standardize the precision of the cut pieces. With the rise of the ready-made garment manufacturing industry, large-scale production has placed higher demands on cutting speed and consistency, and manual cutting has gradually become unable to match the production rhythm of the assembly line.
[0003] Because some existing garment fabric cutting devices do not clean various impurities attached to the fabric surface before cutting, including dust picked up during storage and transportation, fiber debris and hair left over from the production process, these devices are prone to blade wear during cutting or irregular gaps on the edges of the cut pieces, affecting cutting accuracy. Therefore, improvements are needed. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that some existing devices do not clean various impurities attached to the fabric surface before cutting, including dust picked up during storage and transportation, fiber debris and hair left over from the production process, which can easily cause blade wear or irregular gaps on the edges of the cut pieces, affecting the cutting accuracy. Therefore, this invention proposes a garment fabric cutting device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a garment fabric cutting device, comprising a support leg, a worktable fixedly connected to the top of the support leg, an mounting frame fixedly connected to one side of the top of the worktable, a driving component provided on the upper surface of the mounting frame, a cutting component fixedly connected to the output end of the driving component, the cutting component being movably connected to the interior of the mounting frame, flattening devices provided on both sides of the worktable, each flattening device including a mounting groove, the mounting groove being opened on both sides of the worktable, a threaded rod provided inside the mounting groove, a movable frame threadedly connected to the surface of the threaded rod, the movable frame being movably connected to the surface of the worktable, movable grooves being opened on both sides of the movable frame, movable rods being movably connected inside the movable grooves, and a flattening roller provided on one side of the movable rod.
[0006] Furthermore, a hydraulic telescopic rod is provided at the top of the movable frame, and the bottom of the hydraulic telescopic rod is fixedly connected to the top of the movable rod.
[0007] Furthermore, connecting rods are fixedly connected to both sides of the movable rod, and a movable shaft is rotatably connected to the side of the connecting rod away from the movable rod. The movable shaft is rotatably connected between the two connecting rods.
[0008] Furthermore, the flattening roller is fixedly connected to the surface of the movable shaft, a support block is fixedly connected to one side of the support leg, a limit seat is fixedly connected to the top of the support block, and a small gear is rotatably connected to the upper surface of the limit seat.
[0009] Furthermore, a large gear is meshed with the bottom of the small gear, and a rotating roller is fixedly connected inside both the small gear and the large gear. The rotating roller is disposed between two limiting seats, and a cleaning roller is fixedly connected to the surface of the rotating roller.
[0010] Furthermore, a first motor is provided on one side of the rotating roller, and the output end of the first motor is fixedly connected to one side of the rotating roller.
[0011] Furthermore, there are two threaded rods. One threaded rod is fixedly connected to one side of a sprocket, and the other threaded rod is fixedly connected to one side of a sprocket. The surfaces of the sprocket and the sprocket are connected to the same chain. A second motor is installed inside the sprocket, and the output end of the second motor is fixedly connected to the inside of the sprocket.
[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0013] 1. In this invention, by setting a flattening device, the fabric is first passed between two cleaning rollers. Simultaneously, the output of the first motor drives the rotating rollers to rotate, which in turn drives the pinion gear, which in turn drives the large gear, thus driving both rotating rollers to rotate simultaneously. This allows the two cleaning rollers to clean the dust and impurities on the surface of the fabric. The fabric is then placed on the worktable. At this point, the output of the second motor drives the second sprocket to rotate, which in turn drives the chain to rotate, causing both sprockets to rotate simultaneously. This causes the threaded rods to rotate, and the rotation of the two threaded rods to move the movable frame back and forth. Simultaneously, the fabric can be... The hydraulic telescopic rod drives the movable rod to rise and fall inside the movable groove, thereby causing the movable shaft between the connecting rods to drive the flattening roller to rotate, flattening the fabric. Then, the drive component drives the cutting component to cut the fabric. The cleaning device can effectively remove various impurities attached to the fabric surface, including dust picked up during storage and transportation, fiber debris and hair left over from the production process. If these impurities are not treated, they can easily cause blade wear during cutting or cause irregular gaps on the edges of the cut pieces, affecting the cutting accuracy. Flat fabric is subjected to more even force during cutting, which can avoid uneven local stretching caused by wrinkles, ensure that the shape of the cut pieces matches the design size highly, and reduce misalignment problems during splicing.

[0021] Please see Figure 1-5 The present invention provides a technical solution: a garment fabric cutting device, including a support leg 1, a workbench 2 fixedly connected to the top of the support leg 1, a mounting frame 3 fixedly connected to one side of the top of the workbench 2, a drive component 4 provided on the upper surface of the mounting frame 3, a cutting component 5 fixedly connected to the output end of the drive component 4, and flattening devices 6 provided on both sides of the workbench 2.
[0022] The specific setup and function of its flattening device 6 will be explained below.
[0023] In this embodiment: the flattening device 6 includes a mounting groove 61, which is opened on both sides of the workbench 2. A threaded rod 62 is provided inside the mounting groove 61. A movable frame 63 is threadedly connected to the surface of the threaded rod 62. Movable grooves 64 are opened on both sides of the movable frame 63. A movable rod 65 is movably connected inside the movable groove 64. A flattening roller 69 is provided on one side of the movable rod 65.
[0024] Specifically, a hydraulic telescopic rod 66 is provided on the top of the movable frame 63, and the bottom of the hydraulic telescopic rod 66 is fixedly connected to the top of the movable rod 65.
[0025] Specifically, connecting rods 67 are fixedly connected to both sides of the movable rod 65, and a movable shaft 68 is rotatably connected to the side of the connecting rod 67 away from the movable rod 65.
[0026] Specifically, the flattening roller 69 is fixedly connected to the surface of the movable shaft 68, a support block 610 is fixedly connected to one side of the support leg 1, a limit seat 611 is fixedly connected to the top of the support block 610, and a small gear 612 is rotatably connected to the upper surface of the limit seat 611.
[0027] Specifically, the bottom of the small gear 612 is meshed with the large gear 613, and a rotating roller 614 is fixedly connected inside both the small gear 612 and the large gear 613. The rotating roller 614 is located between the two limit seats 611, and a cleaning roller 615 is fixedly connected to the surface of the rotating roller 614.
[0028] Specifically, a first motor 616 is provided on one side of the rotating roller 614, and the output end of the first motor 616 is fixedly connected to one side of the rotating roller 614.
[0029] Specifically, there are two threaded rods 62. One threaded rod 62 is fixedly connected to one side of a sprocket 617, and the other threaded rod 62 is fixedly connected to one side of a sprocket 618. The surfaces of sprocket 617 and sprocket 618 are connected by the same chain 619. A second motor 620 is installed inside sprocket 618, and the output end of the second motor 620 is fixedly connected inside sprocket 618.
[0030] The effect achieved by the above components is as follows: by setting the flattening device 6, the output end of the second motor 620 can drive the second sprocket 618 to rotate. During the operation, the chain 619 will rotate, which will drive the first sprocket 617 and the second sprocket 618 to rotate simultaneously, thereby causing the threaded rod 62 to rotate. The rotation of the two threaded rods 62 will drive the movable frame 63 to move back and forth. At the same time, the hydraulic telescopic rod 66 can drive the movable rod 65 to rise and fall inside the movable groove 64, thereby causing the movable shaft 68 between the connecting rods 67 to drive the flattening roller 69 to rotate, so that the flattening roller 69 flattens the fabric. Flattening the fabric can increase its accuracy during cutting.
[0031] Working principle: By setting up the flattening device 6, the fabric is first passed between two cleaning rollers 615. At the same time, the output of the first motor 616 drives the rotating roller 614 to rotate, which in turn drives the small gear 612 to rotate. The rotation of the small gear 612 drives the large gear 613 to rotate, thereby driving the two rotating rollers 614 to rotate simultaneously. This causes the two cleaning rollers 615 to rotate and clean the dust and impurities on the surface of the fabric. The fabric is then placed on the surface of the worktable 2. At this time, the output of the second motor 620 drives the second sprocket 618 to rotate. During the rotation, the chain 619 rotates, which in turn drives the first sprocket 617 and the second sprocket 618 to rotate simultaneously, thereby rotating the threaded rod 62. The rotation of the two threaded rods 62 drives the movable frame. The fabric moves back and forth. While moving, the hydraulic telescopic rod 66 drives the movable rod 65 to rise and fall inside the movable groove 64, thereby causing the movable shaft 68 between the connecting rods 67 to drive the flattening roller 69 to rotate, flattening the fabric. Then, the drive assembly 4 drives the cutting assembly to cut the fabric. The cleaning device can effectively remove various impurities attached to the fabric surface, including dust picked up during storage and transportation, fiber debris and hair left over from the production process. If these impurities are not treated, they can easily cause blade wear during cutting or cause irregular gaps on the edges of the cut pieces, affecting the cutting accuracy. Flat fabric is subjected to more even force during cutting, which can avoid uneven local stretching caused by wrinkles, ensure that the shape of the cut pieces matches the design size highly, and reduce misalignment problems during splicing.
