Description

Technical Field

[0001] This utility model belongs to the field of textile processing technology, specifically a textile edge anti-loosening locking device. Background Technology

[0002] Textiles refer to products made from textile fibers through processing and weaving. The definition can be divided into narrow and broad senses. In a narrow sense, it mainly refers to two categories: woven fabrics and knitted fabrics. In a broad sense, it covers the entire chain from spinning to finished products, including raw materials such as yarn, silk, and chemical fibers, as well as finished products such as clothing, home textiles, and industrial fabrics. It even extends to products that use yarn, such as fabric toys and hand-crocheted items. Textile processing techniques include cutting, overlocking, and folding. Among them, overlocking is used to prevent the edges from unraveling, curling, or fiber shedding, thereby improving the structural stability of the fabric and extending its service life.

[0003] During the edge-locking process of textiles, the sewing device is used to sew along the corresponding edge. However, during the edge-locking process, the textile edge fabric is prone to gradually shifting, increasing the alignment error and requiring repeated adjustments, which in turn increases the workload and affects the overall efficiency and quality consistency of the edge-locking process.

[0004] Therefore, a textile edge-locking device to prevent fraying is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a textile edge anti-loosening locking device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The textile edge anti-loosening locking device of this utility model includes an installation structure, the installation structure includes an installation base and a pressure foot, the pressure foot is provided with locking structures on both sides, the locking structure includes a pressure plate, the top two sides of the pressure plate are connected to fixed seats, the fixed seats are inserted with connecting shafts, and the bottom of the pressure plate is equipped with an anti-rolling pressing component, the anti-rolling pressing component includes a lateral limiting plate and a pressing plate.

[0007] Preferably, the mounting base has an internal mounting slot, a matching pressure foot is fixedly mounted on the bottom of the mounting base, the outer wall of the pressure foot has a connecting groove, the connecting groove extends to the other side of the pressure foot, and the connecting groove has a circular hole structure.

[0008] Preferably, the pressure plate in the locking structure has a sewing area inside, the fixing seat has two sets symmetrically distributed, the outer wall of the fixing seat has a round hole, and the connecting shaft is inserted into the fixing seat through the round hole.

[0009] Preferably, the connecting shaft extends through the connecting groove on the pressure foot to the outside of the fixed seat, and fixed retaining rings are fixedly sleeved at both ends of the connecting shaft.

[0010] Preferably, the anti-rolling edge pressing assembly has two sets located on both sides of the bottom of the pressing plate, and the outer side of the lateral limiting plate is fixedly connected with pressing plates of equal length.

[0011] Preferably, the outer wall of the pressing plate is provided with a "U"-shaped groove, which extends along its length and penetrates to the other end face of the pressing plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model provides a textile edge anti-loosening overlock device. It is fixed to the sewing machine head by a mounting base. The bottom of the presser foot presses the textile surface. When the textile edge is fed in, the pressure plate in the overlock structure is floatingly connected to the presser foot through a connecting shaft, which can adapt to the fabric thickness. The lateral limiting plate of the anti-rolling pressure assembly clamps the edge from both sides to prevent lateral displacement. The pressing plate presses the fabric edge flatly to the sewing area through its "U"-shaped groove, so that the sewing needle performs overlock sewing along the "U"-shaped groove. The pressing plate provides uniform pressure while avoiding interference with the stitches, so as to keep the edge flat and tight, suppress the sewing fabric edge from unraveling and curling, and improve the firm and efficient overlock effect.

[0014] 2. This utility model provides a textile edge anti-loosening locking device, which is equipped with an anti-rolling pressing component. Through the cooperation of the lateral limiting plate and the pressing plate, the edge of the fabric is firmly pressed against the sewing area, avoiding the lateral movement of the fabric caused by the needle bar during the sewing process. This preemptively curbs the tendency of the fabric edge to curl, thereby ensuring the continuity and safety of the sewing process. Attached Figure Description

[0022] 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.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a textile edge anti-loosening locking device, including an installation structure 1, which includes an installation base 101 and a presser foot 102. Locking structures 2 are provided on both sides of the presser foot 102. The locking structure 2 includes a pressure plate 201. Fixed seats 202 are connected to the top two sides of the pressure plate 201. A connecting shaft 203 is inserted into the fixed seat 202. An anti-rolling pressing component 3 is installed at the bottom of the pressure plate 201. The anti-rolling pressing component 3 includes a lateral limiting plate 301 and a pressing plate 302.

[0025] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 101 has a mounting slot inside, and a matching presser foot 102 is fixedly mounted on the bottom of the mounting base 101. The outer wall of the presser foot 102 has a connecting groove 103 that extends to the other side of the presser foot 102. The connecting groove 103 has a circular hole structure. During operation, the mounting base 101 is fixed to the corresponding parts of the sewing machine through the mounting slot inside. The connecting groove 103 at the bottom of the presser foot 102 is a through circular hole for passing through the connecting shaft 203, so that the presser foot 102 and the overlock structure 2 form a movable connection. During sewing, the presser foot 102 and the overlock structure 2 can be finely adjusted relative to each other to adapt to changes in the position of the fabric during movement.

[0026] Furthermore, such as Figure 2 and Figure 4As shown, the pressure plate 201 in the overlock structure 2 has a sewing area inside, and the fixing seat 202 has two sets symmetrically distributed. The outer wall of the fixing seat 202 has a round hole, and the connecting shaft 203 is inserted into the fixing seat 202 through the round hole. During operation, the sewing area in the middle of the pressure plate 201 provides a channel for the sewing needle to ensure that the stitches are formed normally. The pressure plate 201 in the overlock structure 2 is floatingly connected to the presser foot 102 through the connecting shaft 203. The symmetrically distributed fixing seats 202 are connected to the connecting shaft 203 through their round holes, so that the pressure plate 201 can swing slightly around the shaft, automatically adjusting the pressure when the fabric passes through, avoiding excessive compression or loosening.

[0027] Furthermore, such as Figure 3 As shown, the connecting shaft 203 extends through the connecting groove 103 on the presser foot 102 to the outside of the fixed seat 202, and fixed retaining rings are fixedly sleeved at both ends of the connecting shaft 203. During operation, the connecting shaft 203 passes through the connecting groove 103 of the presser foot 102 and extends out of the fixed seat 202. The fixed retaining rings at both ends limit the connecting shaft 203 to prevent it from falling off, so that the presser plate 201 can rotate around the axis while maintaining axial stability, thus maintaining the positional accuracy of the overlock structure 2 during sewing.

[0028] Furthermore, such as Figure 3 and Figure 4 As shown, the anti-rolling edge pressing assembly 3 has two sets located on both sides of the bottom of the pressing plate 201, and a pressing plate 302 of equal length is fixedly connected to the outer side of the lateral limiting plate 301. During operation, the two sets of anti-rolling edge pressing assemblies 3 are located on both sides of the bottom of the pressing plate 201, and the lateral limiting plate 301 provides lateral obstruction from the outer side of the fabric edge to prevent the fabric from tilting. The "U"-shaped groove inside the pressing plate 302 restricts the direction of the fabric, effectively suppressing edge curling and offset, thereby improving the efficiency of the overlocking work.

[0029] Furthermore, such as Figure 4 As shown, the outer wall of the pressing plate 302 has a "U"-shaped groove that extends along its length and extends to the other end face of the pressing plate 302. During operation, the "U"-shaped groove on the pressing plate 302 extends along its length to form a continuous opening. This groove accommodates the seam thread and reduces the contact area with the fabric during pressing, ensuring the pressing effect while avoiding interference with stitch formation. At the same time, it allows the fabric to pass through smoothly, reducing frictional resistance.

[0030] Working principle: This device works in a coordinated manner through mechanical linkage to prevent fraying and curling of textile edges. At the start of operation, the mounting base 101 fixes the entire device to the sewing machine. The fabric edge is guided under the presser foot 102, which presses down to stabilize the fabric body. The overlock structures 2 on both sides adaptively wrap around the fabric edge under the adjustment of the connecting shaft 203. The lateral limiting plate 301 and the pressing plate 302 on one side of the anti-curling pressing component 3 at the bottom firmly press the fabric edge against the sewing area, preventing the fabric from shifting laterally due to the needle bar during sewing, thus improving the firmness and efficiency of the overlock effect. The anti-curling pressing component 3, in conjunction with the overlock structure 2, can make slight dynamic adjustments as the needle moves during the overlock operation, maintaining constant pressure. The "U"-shaped groove on the pressing plate 302 ensures smooth thread passage and reduces friction. The fabric edge is continuously pressed and guided to complete the stitching, improving the efficiency and quality of the overlock work.

[0031] 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.
