Description

Technical Field

[0001] This utility model relates to the field of fabric conveying technology, specifically a fabric misalignment correction device for overlock sewing machines. Background Technology

[0002] Fabrics are commonly used materials in decoration, including various types such as synthetic fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tape, and flannel. Fabrics are typically made from various raw materials processed into yarn, then woven into greige fabric, and finally dyed to become finished products. Fabrics are widely used in clothing, home decoration, automotive interiors, and many other fields.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221439858U) discloses a multi-layer fabric conveying device. Its general description includes a support plate on which conveying structures are mounted. The number of conveying structures is not less than two, and they are equidistantly distributed on the support plate. Each conveying structure includes a circular groove, a second bearing, a conveying roller, a fixed sleeve, a movable sleeve, and fabric. The circular groove is formed on the support plate. The outer ring of the second bearing is installed within the circular groove, and the conveying roller is installed within the inner ring of the second bearing. The fixed sleeve is installed on the conveying roller, and the movable sleeve is fitted onto the conveying roller. The fabric is placed between the fixed sleeve and the movable sleeve. The corresponding conveying roller is installed according to the number of fabric layers. The distance between the movable sleeve and the fixed sleeve is adjusted according to the width of the fabric. After adjustment, a spring in the groove applies an inward force to the ball, fixing the movable sleeve onto the conveying roller, allowing the fabric to pass between the fixed sleeve and the movable sleeve for positioning and conveying.

[0004] The above technical solution achieves flexible adjustment and conveying of fabric through the conveying structure and the movable sleeve. However, during the conveying process, the conveying roller is prone to double-layer misalignment of the fabric, which reduces the conveying efficiency of the fabric and affects the subsequent sewing process, resulting in creases and defective products.

[0005] Therefore, this utility model provides a fabric misalignment correction device for overlock sewing machines to solve the above-mentioned problems. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a fabric misalignment correction device for overlock sewing machines, such as... Figure 1and Figure 2 As shown, the material rack structure 1 includes a support 101. Each support 101 has a limit rod 102 installed inside it. Each support 101 has a roller 103 connected to its bottom. A workbench 4 is provided on one side of the material rack structure 1. A blade assembly structure 2 and a fabric clamp 3 are installed on the top of the workbench 4. An automatic correction structure 6 is installed at the bottom of the blade assembly structure 2. The automatic correction structure 6 includes an adjustment structure and a correction structure. Boxes 401 are connected to both sides of the workbench 4.

[0028] Limiting rods 102 are fixedly installed on both sides inside the bracket 101. Rollers 103 are symmetrically installed at the bottom of the bracket 101. The surface of the limiting rods 102 is covered with fabric 104.

[0029] When the equipment is in use, the material rack structure 1 moves via the bottom rollers 103, and the limiting rods 102 guide the fabric 104 into the worktable 4. The symmetrically distributed limiting rods 102 constrain the lateral movement range of the fabric 104, preventing the fabric 104 from curling or tilting, thereby ensuring the efficiency of the fabric 104 conveying operation. The rollers 103 roll synchronously to ensure the convenience of feeding.

[0030] Furthermore, in order to improve the conveying efficiency, such as Figure 3 , Figure 4 and Figure 5 As shown, the workbench 4 includes a housing 401, and a support frame 402 is fixedly connected to the top of the housing 401. The support frame 402 has two sets of symmetrically distributed support frames. A guide rail is connected to the inner side of the support frame 402, and a fabric clamp 3 is installed on one side of the guide rail.

[0031] The blade assembly structure 2 includes a mounting base 201. The mounting base 201 has two sets of blades located on both sides of the top of the workbench 4. A slide rod 202 is fixedly installed on the inner side of the mounting base 201, and a cutter 203 is movably sleeved on the outer surface of the slide rod 202.

[0032] The top of the workbench 4 is equipped with an overlock machine 5, which is located on one side of the mounting base 201. The overlock machine 5 includes an operating box 502, and multiple sets of adjustment knobs 501 are evenly arranged on the outside of the operating box 502. A fixed blade 503 is installed on one side of the operating box 502.

[0033] The adjustment structure includes a connecting seat 601, with several sets of tension rollers 602 arranged inside the connecting seat 601, and a motor 603 installed outside the connecting seat 601. The motor 603 is electrically connected to one end of the pressure roller 604 inside the connecting seat 601.

[0034] When the equipment is in use, after the fabric 104 is tensioned by the fabric clamp 3, the cutter assembly 2 cuts the fabric. The automatic correction structure 6 at the bottom, through the linkage of the adjustment structure and the correction structure, guides the fabric clamp 3 to slide along the direction of fabric 104 movement via the guide rail of the support frame 402. The pressure roller 604 rotates to press creases onto the surface of the fabric 104, increasing the crease marks on the fabric 104, which facilitates the subsequent winding and packaging work. The tension roller 602 automatically adjusts its position according to the tightness of the fabric 104, preventing wrinkles in the fabric 104, thereby ensuring the fabric 104 moves smoothly during transport. The fabric 104 maintains stable tension during conveying, ensuring its smoothness and preventing positional deviation. During shearing, the cutter 203 cuts the fabric 104 by moving laterally along the slide bar 202. During overlocking, the control knob 501 sets the overlocking parameters, and the fixed blade 503 works in conjunction with the correction device to ensure the fabric 104 edges are aligned, guaranteeing the overlocking effect.

[0035] Furthermore, in order to enhance the effectiveness of the conveying process, such as Figure 6 and Figure 7 As shown, the correction structure includes a side plate 605. The side plate 605 has two sets of corresponding distributions with the connecting seat 601. The inner side of the side plate 605 is symmetrically provided with sliding grooves. The two sides inside the sliding grooves are installed with the two ends of the connecting rod 607. A clamping device 606 is fixedly inserted into the top of the side plate 605. An indentation roller 608 is provided in the center of the inside of the side plate 605. A corrector 609 is sleeved on the outside of the connecting rod 607.

[0036] When the device is in use, the clamping device 606 presses down to fix the fabric 104, and the corrector 609 slides along the connecting rod 607. When the fabric 104 shifts laterally, the sensor built into the corrector 609 triggers the control system displacement command. The corrector 609 slides laterally along the connecting rod 607, pushing the edge of the fabric 104 to move towards the target position. After completing a single correction, the corrector 609 returns to the initial position, ready for the next action. At the same time, the synergistic action of the indentation roller 608 and the corrector 609 aligns the edge of the fabric 104 and presses out guide marks.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
