Description

Technical Field

[0001] This utility model relates to the field of webbing manufacturing technology, and in particular to a webbing edge locking structure. Background Technology

[0002] When processing ribbon, it is necessary to use sewing thread to overlock the raw edges or seams of the ribbon to prevent it from unraveling. This process is also known as "overlocking," "locking," or "binding." In ancient times, this was done by hand, but modern overlocking machines or sewing machines are used. The most common method is a 3-needle, 5-thread overlock stitch, but 4-needle or 5-needle overlock stitches are also used to reinforce the stitches. During the overlocking process, an additional thread is pressed, double-threaded, or chain-cut thread is applied to further strengthen the stitches and prevent fraying or tearing. Currently, overlocking devices for ribbon processing are usually hand-sewn, which is inefficient, results in inconsistent sewing widths, and makes it difficult to fix the sewn fabric in place, leading to poor sewing quality. Therefore, the use of overlocking devices for ribbon is increasing, gradually replacing manual labor.

[0003] Currently, existing webbing overlocking devices still have shortcomings. When processing, users still need to manually fold the edge of the fabric and place it under the sewing needle. However, the high-speed movement of the sewing needle is very dangerous for users, increasing the risk of labor. In addition, the overlocking operation can only be performed on one side of the webbing at a time, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a webbing edge locking structure.

[0005] The technical solution of this utility model is a webbing edge locking structure, comprising:

[0006] frame;

[0007] Two fabric support platforms are symmetrically arranged and slidably mounted on the upper part of the frame. The frame is equipped with a power unit for driving the two fabric support platforms to move closer or further apart.

[0008] Two limiting shells are symmetrically arranged and fixedly connected to the fabric support platforms on both sides respectively;

[0009] Two sewing machines are arranged side by side on the top of the frame. Sewing machine mounting brackets are connected to fabric support platforms on both sides, and the two sewing machines are mounted on the sewing machine mounting brackets on both sides respectively. Two sewing machine bases are slidably installed on the frame, and the two sewing machine bases are located directly below the two sewing machines, and the two sewing machine bases are connected to the fabric support platforms on both sides respectively.

[0010] Preferably, it also includes a flattening mechanism, which includes a pressure roller. Two mounting seats are arranged side by side on the upper end of the frame. Each mounting seat has a sliding hole. A rotating seat is slidably installed on the inner side of each sliding hole. The pressure roller is rotatably installed between the two rotating seats.

[0011] Preferably, a spring is vertically arranged inside the sliding hole, the rotating seat is slidably arranged on the spring, and a guide rod is sleeved on the spring.

[0012] Preferably, the power assembly includes an electric push rod, a gear, and two racks. The electric push rod is mounted on the frame and its output shaft is connected to a fabric support platform on one side. The gear is rotatably mounted on the frame, and the two racks are meshed with the gear and connected to the fabric support platforms on both sides respectively.

[0013] Preferably, the cross-section of the limiting shell is U-shaped.

[0014] Preferably, the cross-section of the fabric support platform is "L" shaped.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] 1. In the technical solution, the fabric support platform and the limiting shell are designed to form a U-shaped channel between the limiting shell and the fabric support platform so that the end of the fabric can pass through, thereby facilitating the automatic folding of the end of the fabric and making it easier to lock the edges of the fabric later.

[0017] 2. The distance between the two fabric support platforms can be adjusted by the set power component, so it can be used for overlock processing of fabrics of different widths, and its applicability is strong. Attached Figure Description

Detailed Implementation

[0022] Example 1

[0024] Two fabric support platforms 3 are symmetrically arranged and slidably mounted on the upper end of the frame 1. The cross-section of the fabric support platform 3 is "L" shaped. The frame 1 is equipped with a power component for driving the two fabric support platforms 3 to move closer or further apart. The power component includes an electric push rod 5, a gear 14 and two racks 13. The electric push rod 5 is mounted on the frame 1 and its output shaft is connected to one side of the fabric support platform 3. The gear 14 is rotatably mounted on the frame 1. The two racks 13 are meshed with the gear 14 and are respectively connected to the fabric support platforms 3 on both sides. Two limiting shells 4 are symmetrically arranged and fixedly connected to the fabric support platforms 3 on both sides respectively. The cross-section of the limiting shells 4 is "U" shaped. Two sewing machines 6 are arranged side by side above the frame 1. Sewing machine mounting brackets 7 are connected to the fabric support platforms 3 on both sides. The two sewing machines 6 are respectively mounted on the sewing machine mounting brackets 7 on both sides. Two sewing machine bases 2 are slidably installed on the frame 1. The two sewing machine bases 2 are located directly below the two sewing machines 6 respectively, and the two sewing machine bases 2 are respectively connected to the fabric support platforms 3 on both sides.

[0025] In this embodiment, the fabric support platform 3 and the limiting shell 4 are configured to form a U-shaped channel between the limiting shell 4 and the fabric support platform 3, allowing the fabric end to pass through. This facilitates automatic folding of the fabric end, which in turn facilitates subsequent hemming. One end of the fabric is fixed to the take-up roller (not shown), and the take-up roller is driven to rotate and move the fabric. During the movement of the fabric, two sewing machines 6 are started, which enables synchronous hemming of both sides of the fabric, improving the working efficiency of the device.

[0026] It should be added that the equipment is controlled by the PLC controller 10 in this technical solution.

[0027] The distance between the two fabric support platforms 3 can be adjusted by the set power component, so that it can be used for overlock processing of fabrics of different widths, and its applicability is strong.

[0029] like Figures 1-4 As shown, the webbing overlock structure proposed in this embodiment includes a frame 1, a flattening mechanism, two fabric support platforms 3, two limiting shells 4, and two sewing machines 6.

[0030] Two fabric support platforms 3 are symmetrically arranged and slidably mounted on the upper end of the frame 1. The cross-section of the fabric support platform 3 is "L" shaped. The frame 1 is equipped with a power component for driving the two fabric support platforms 3 to move closer or further apart. The power component includes an electric push rod 5, a gear 14 and two racks 13. The electric push rod 5 is mounted on the frame 1 and its output shaft is connected to one side of the fabric support platform 3. The gear 14 is rotatably mounted on the frame 1. The two racks 13 are meshed with the gear 14 and are respectively connected to the fabric support platforms 3 on both sides.

[0031] The flattening mechanism includes a pressure roller 11. Two mounting seats 12 are arranged side by side on the upper end of the frame 1. Each mounting seat 12 has a sliding hole 121. A rotating seat 15 is slidably installed on the inner side of each sliding hole 121. The pressure roller 11 is rotatably installed between the two rotating seats 15.

Under the elastic force of the spring 17, the pressure roller 11 is pressed tightly against the upper surface of the fabric, thereby flattening the fabric surface, reducing wrinkles, and allowing the fabric in the overlock section to be in a taut state, thus improving the overlock effect of the fabric. The fabric mentioned above is webbing.
