Description

Technical Field

[0001] The invention relates to a production process of composite stretch fabric. Background Art

[0002] Stretch fabric, as the name suggests, is stretchy grey fabric. The ribbed structure gives the grey fabric greater elasticity and is often used as an inner interlayer shaping material for handbags and wallets. It can also be used for the collar and cuffs of T-shirts to give them a better slimming effect. There are many composite structures derived from the rib structure, mainly ribbed air layer structure and point pattern structure. The ribbed air layer structure is composed of ribbed structure and plain needle structure. This structure has small lateral extensibility and good dimensional stability. It has the advantages of thickness and stiffness. The point pattern structure is composed of incomplete rib structure and incomplete plain needle structure. According to the configuration order of the two coils in a complete structure, there are Swiss type and French type. The Swiss type point pattern structure has a compact structure, small extensibility and good dimensional stability, while the French type point pattern structure has clear longitudinal coil lines, a plump surface and a large width. Both structures are widely used in the production of knitted outerwear. Currently, in the production process of composite stretch fabrics, manual cutting of the composite stretch fabrics is usually required to facilitate subsequent use of the composite stretch fabrics. However, manual cutting is not only labor-intensive, but also easily leads to uneven cutting, resulting in great waste. Summary of the Invention

[0021] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] The technical solution specifically implemented in the present invention is:

[0023] like Figures 1 to 4 As shown, a production process of composite stretch fabric, using a cutting device to cut the composite stretch fabric, the cutting device includes a frame 1, a cutting mechanism, a pressing mechanism and a conveying mechanism;

[0024] A cutting table 2 is provided on the top of the frame 1, and the conveying mechanism is installed on one side of the cutting table 2 through a bracket 3;

[0025] The cutting mechanism includes a cutting groove 4 provided on the cutting table 2, one end of the cutting groove 4 passes through the front end side wall of the cutting table 2, a support plate 5 is provided below the cutting table 2, a mounting plate 6 is provided on the top of the rear end of the support plate 5, a cutting motor 7 and two horizontal guide rods 8 respectively located on both sides of the cutting motor 7 are provided on the mounting plate 6, a slide 9 is mounted on the two horizontal guide rods 8, the output shaft of the cutting motor 7 is connected to a horizontal screw rod 10 threadedly connected to the slide 9, a knife seat 11 is provided on the top of the slide 9, a cutter 12 is installed on the top of the knife seat 11, and the top of the cutter 12 passes through the cutting groove 4 and extends above the cutting table 2;

[0026] The pressing mechanism includes a vertical plate 13 provided at the top of the rear end of the cutting table 2, a horizontal plate 14 provided on the vertical plate 13, a pressing cylinder 15 provided on the top of the horizontal plate 14, a piston rod of the pressing cylinder 15 passing through the horizontal plate 14 and connected to a lifting plate 16, two long strip-shaped pressing blocks 17 provided at the bottom of the lifting plate 16, the two pressing blocks 17 being respectively located on either side of the cutting groove 4, and the length direction of the pressing blocks 17 being parallel to the length direction of the cutting groove 4; the specific process of cutting the composite stretch fabric using the cutting equipment is as follows:

[0027] First, the composite stretch fabric to be cut is conveyed to the cutting table 2 by the conveying mechanism;

[0028] Then, the piston rod of the pressing oil cylinder 15 is controlled to extend to move the lifting plate 16 downward, and the lifting plate 16 drives the pressing block 17 downward to press and fix the composite stretch fabric;

[0029] Finally, the cutting motor 7 is controlled to rotate in the forward direction to rotate the horizontal screw rod 10, which drives the slide 9 to move from the rear end to the front end of the cutting table 2, so that the cutter 12 moves along the cutting groove 4 and cuts the composite stretch fabric.

[0030] Furthermore, the clamping mechanism also includes two elongated pulling blocks 18, the two pressing blocks 17 are located between the two pulling blocks 18, and the two pressing blocks 17 correspond one-to-one to the two pulling blocks 18, the bottom surface of the pressing block 17 is located above the bottom surface of the pulling block 18, and the side of the pressing block 17 is provided with a first inclined surface 19, the side of the pulling block 18 is provided with a second inclined surface 20, and the second inclined surface 20 of the pulling block 18 is in contact with the first inclined surface 19 of the corresponding pressing block 17, the first inclined surface 19 is provided with an inclined groove 21, the second inclined surface 20 is provided with a slider 22 slidably connected to the inclined groove 21, the pulling block 18 is provided with a fixed block 23 on the side facing away from the corresponding pressing block 17, the fixed block 23 is fixedly connected to the bottom of the lifting plate 16, and an inclined return spring 24 is connected between the fixed block 23 and the pulling block 18. By adopting the above scheme, when the pressing mechanism is pressing and fixing the composite elastic fabric, first, the lifting plate 16 drives the pressing block 17 and the pulling block 18 to move downward together, and then the pulling block 18 first contacts the composite elastic fabric and presses it, and then the lifting plate 16 continues to drive the pressing block 17 downward. During this process, the pressing block 17 will make the pulling block 18 move toward the fixed block 23 and compress the return spring 24 through the contact and cooperation between the first inclined surface 19 and the second inclined surface 20, so that the two pulling blocks 18 will pull the pressed composite elastic fabric toward both sides of the cutting groove 4, so that the composite elastic fabric is tightened, so as to better cut the composite elastic fabric; until the pressing block 17 descends to contact the composite elastic fabric and applies a certain pressure to it, the lifting plate 16 stops descending, thereby completing the pressing operation of the composite elastic fabric.

[0031] Furthermore, a protective pad 25 is provided at the bottom of the pressing block 17. By adopting the above solution, the protective pad 25 contacts the composite stretch fabric, thereby preventing the pressing block 17 from directly contacting the composite stretch fabric and causing damage to the composite stretch fabric.

[0032] Furthermore, a friction plate 26 is provided at the bottom of the pull block 18. By adopting the above solution, the friction plate 26 contacts the composite stretch fabric, and the friction plate is used to increase the friction between the pull block 18 and the composite stretch fabric, so that the pull block 18 can better pull the pressed composite stretch fabric.

[0033] Furthermore, the conveying mechanism includes a first roller frame 27 fixed to the top of the bracket 3. A conveying roller 28 and a pressure roller 29 are rotatably mounted on the first roller frame 27. The conveying roller 28 is located below the pressure roller 29, and the rotating shaft of the conveying roller 28 is connected to a conveying motor 30. By adopting this solution, the composite stretch fabric is pressed between the conveying roller 28 and the pressure roller 29. By controlling the operation of the conveying motor 30 to drive the conveying roller 28 to rotate, the rotation of the conveying roller 28 drives the composite stretch fabric to move, thereby achieving the conveyance of the composite stretch fabric.

[0034] Furthermore, the cutting device further includes a guide mechanism comprising a second roller frame 31 fixed to the top of the bracket 3. The second roller frame 31 is positioned between the first roller frame 27 and the cutting table 2. A guide roller 32 is rotatably mounted on the second roller frame 31. Two limiting rings 33 are sleeved on the guide roller 32. The limiting rings 33 are movable along the axial direction of the guide roller 32. The limiting rings 33 are provided with a jackscrew hole into which a jackscrew 34 is threadedly connected. One end of the jackscrew 34 abuts the guide roller 32. With this arrangement, the composite stretch fabric passes between the two limiting rings 33 on the guide roller 32 during transport, where the two limiting rings 33 prevent the composite stretch fabric from deflecting, ensuring accurate transfer to the cutting table. Furthermore, the limiting rings 33 are movable along the axial direction of the guide roller 32, thereby adjusting the distance between the two limiting rings 33 to match the width of the composite stretch fabric.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
