Description

Technical Field

[0001] The utility model relates to the technical field of garment-making equipment, and specifically relates to a garment-making fabric cutting device. Background Art

[0002] In garment production, since there are generally frayed edges on both sides of the fabric and the frayed edges are prone to unthreading, when cutting garment fabrics, the frayed edges are usually cut off to make the two sides of the fabric smoother, so that the clothes made are not easy to unthread. The existing methods for cutting the frayed edges on both sides of the fabric are generally carried out by manual and machine cutting. Manual cutting is slow, time-consuming and laborious, and the labor intensity is relatively large. The edge cutting speed of machine equipment is relatively fast, but the existing edge cutting equipment usually cannot limit the fabric, and it is easy to deviate. Moreover, since most of the fabrics for making clothes are relatively soft, during the cutting process, the fabric is prone to wrinkling under the action of the cutting knife, which makes the edge cutting prone to deviation. At the same time, the edge cutting position needs to be measured manually, which not only has many operation steps, increases the workload, but also is time-consuming and laborious, with low working efficiency and is not conducive to actual use. In addition, the cut frayed edges need to be manually cleaned and collected, which is not only time-consuming and laborious, but also has potential safety hazards and affects the normal production of garments.

In actual manufacturing, the edge cleaning sweeping piece 47 is preferably made of rubber material.

[0030] Embodiment 7:

[0031] According to the attached drawings of the specification Figure 1-2 As shown, the difference between this embodiment and Embodiments 1-6 is that inclined guide plates 52 are respectively fixed on the frame 1 near the left and right edges of the workbench 2. Material truck slides 53 are respectively provided on the left and right sides of the frame 1 and a waste material truck 54 is installed. The waste material truck 54 is located below the inclined guide plate 52 at the corresponding position, and rollers are installed at the lower end of the waste material truck 54. When the edge cleaning and sheet sweeping device 47 sweeps the fabric frayed edge away from the workbench 2, the fabric frayed edge slides down along the inclined guide plate 52 at the corresponding position and falls into the corresponding waste material truck 54 below, realizing the collection of the fabric frayed edge.

[0032] The usage process of Embodiment 7 of the present utility model is as follows: During use, first, place the fabric with the to-be-cut frayed edge for garment making on the workbench 2, start the lifting air cylinder 12, and the lifting air cylinder 12 drives the lifting cross frame 3 to approach the workbench 2. The lifting cross frame 3 drives the left head slider 4, the right head slider 5, the left knife seat 6, the right knife seat 7, the left bearing seat 8, the right bearing seat 9, the left edge cleaning device, the right edge cleaning device, the left pressing device, and the right pressing device to approach the workbench 2. Secondly, adjust the left and right positions of the left head slider 4 and the left trimming knife 22 through the left head motor 55 and the left lead screw 17, and adjust the left and right positions of the right head slider 5 and the right trimming knife 29 through the right head motor 56 and the right lead screw 19. Thirdly, finely adjust the left and right positions of the left roller slider 41 through the left adjusting knob 43 to adjust the distance between the left pressing roller 20 and the left trimming knife 22. Then, the left roller hydraulic rod 44 extends the piston rod downward, driving the left pressing roller 20 of the left pressing device to press the left part of the fabric with the to-be-cut frayed edge on the workbench 2. Next, adjust the distance between the right pressing roller 21 on the right pressing device and the right trimming knife 29, and then press the right part of the fabric through the right pressing roller 21. Then, adjust the cutting depth of the cutter mounting seat 28, the left trimming knife 22, and the right trimming knife 29 through the cutting depth adjusting motor 24, so that the left trimming knife 22 and the right trimming knife 29 can penetrate the fabric with the to-be-cut frayed edge. At this time, the edge cleaning rotating shaft 46 drives the edge cleaning sweeping piece 47 to abut against the fabric with the to-be-cut frayed edge on the workbench 2. Then, start the left feeding motor 33 and the right feeding motor 34. The left feeding gear 35 and the right feeding gear 36 rotate, and the left sliding seat 31, the right sliding seat 32, and the gantry guide frame 10 move relative to the left rack 37 and the right rack 38, thereby driving the left trimming knife 22 and the right trimming knife 29 to continuously cut the fabric with the to-be-cut frayed edge, realizing the trimming of the frayed edge, and separating the frayed edge of the fabric from the fabric body. At the same time, start the sweeping piece driving motor 48. The sweeping piece driving motor 48 drives the sweeping piece driving wheel 49 to rotate. The sweeping piece driving wheel 49 drives the sweeping piece driving wheel 50 to rotate through the sweeping piece transmission belt 51, driving the edge cleaning rotating shaft 46 to drive the edge cleaning sweeping piece 47 to rotate. Under the action of the frictional force between the edge cleaning sweeping piece 47 and the frayed edge of the fabric, the edge cleaning sweeping piece 47 sweeps the frayed edge of the fabric off the workbench 2, realizing the cleaning of the frayed edge of the fabric on the workbench 2. Finally, the frayed edge of the fabric swept off the workbench 2 by the edge cleaning sweeping piece 47 will slide down along the inclined surface of the inclined guide plate 52 into the waste material cart 54, completing the waste collection of the frayed edge of the fabric. When there is more or the waste material cart 54 is full of the frayed edge of the fabric collected, the waste material cart 54 can be pulled out from the side of the frame 1 through the waste material cart slide rail 53, facilitating other treatments for the frayed edge of the fabric in the waste material cart 54. At the same time, the operator can also install other empty waste material carts 54 on the waste material cart slide rail 53 on the side of the frame 1, slide the new waste material cart 54 under the inclined guide plate 52, and continue to collect the frayed edge of the fabric.
