Description

Technical Field

[0001] This utility model relates to an overlock machine, and more specifically, to an overlock machine that prevents deviation. Background Technology

[0002] Garment production refers to the garment production and processing process in the textile industry, including design, cutting, sewing, sizing and packaging. During garment processing, overlock machines are used to sew the edges of the fabric.

[0003] A utility model patent with patent number CN222349286U discloses a garment overlock machine, including a base plate. The overlock machine is bolted to the top right side of the base plate. A controller is bolted to the front right side of the overlock machine. A first frame is bolted to the front side of the base plate. A drive motor is bolted to the right side of the first frame. The output end of the drive motor passes through the inner cavity of the first frame and is fixedly connected to a lead screw. An adjustment plate is threaded on the left side of the lead screw. A movable plate is riveted to the front side of the adjustment plate. A positioning plate is riveted to the rear side of the movable plate. A chip removal mechanism is bolted to the front and rear sides of the left side of the positioning plate. A bracket is riveted to the front and rear sides of the left side of the positioning plate. An electric push rod is bolted to the left side of the inner cavity of the bracket. A dust suction pipe is fixedly connected to the output end of the electric push rod. The right side of the dust suction pipe passes through the positioning plate.

[0004] In this invention, a positioning plate is used to assist in positioning the left side of the fabric. The left side of the fabric is the side furthest from the overlock machine's stitches. Since the fabric is usually soft, it is prone to wrinkling during movement, especially when the fabric is long. Therefore, when positioning at the far end, the fabric is prone to wrinkling and folding. Moreover, when wrinkles occur on the side furthest from the overlock machine's stitches, it is difficult to visually determine whether the fabric below the stitches has shifted, making it difficult for the positioning plate to ensure that the right side of the fabric to be overlocked is aligned with the overlock machine's stitches. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a simple, anti-deviation overlock machine that is positioned close to the presser foot of the overlock machine.

[0006] The technical solution of this utility model is implemented as follows: a lockstitch machine for preventing deviation includes a base and a suspension lockstitch machine set on the base. The suspension lockstitch machine includes a machine body, a pressure foot is provided at the end near the free end of the machine body, and a horizontal moving component that moves along the length direction of the suspension lockstitch machine is provided on the base near the side of the pressure foot. A moving bracket is provided on the horizontal moving component, and a positioning baffle perpendicular to the suspension lockstitch machine is provided on the moving bracket.

[0007] In the aforementioned anti-deviation overlock machine, the horizontal movement component includes a horizontal guide rail mounted on a base on one side of the machine body, a sliding seat mounted on the horizontal guide rail, and an adjusting screw that cooperates with the sliding seat mounted on the horizontal guide rail via a bearing.

[0008] In the aforementioned anti-deviation overlock machine, the movable support includes a mounting suspension mounted on a sliding seat, a mounting plate is provided at the front end of the mounting suspension, and a positioning baffle is provided at the bottom of the mounting plate.

[0009] In the aforementioned anti-deviation overlock machine, the positioning baffle includes several positioning plates, and an angle adjustment component that cooperates with the positioning plates is provided on the movable support; when overlocking the round neck of a garment, the angle adjustment component makes each positioning plate cooperate to form a polygonal guide plate that is close to an arc shape.

[0010] In the aforementioned anti-deviation overlocking machine, the positioning plate includes two first baffles, and two mounting holes are symmetrically provided on the movable support. The first baffles are hinged to the mounting holes via a rotating shaft, and a second baffle is hinged to the free end of each first baffle.

[0011] In the aforementioned anti-deviation overlock machine, the angle adjustment component includes a first screw located at the upper end of the hinge shaft between the first baffle and the second baffle, and a first arc-shaped elongated hole that cooperates with the first screw is provided on the movable bracket, wherein the first arc-shaped elongated hole is concentrically arranged with the mounting hole.

[0012] A second screw is provided at the free end of the second baffle, and a second arc-shaped elongated hole that mates with the second screw is provided on the movable bracket. A third arc-shaped elongated hole is provided at the end of the second arc-shaped elongated hole away from the presser foot. The second arc-shaped elongated hole is concentric with the mounting hole, and the third arc-shaped elongated hole is concentric with one end of the first arc-shaped elongated hole. Nuts are provided on both the first screw and the second screw for clamping and fixing the movable bracket.

[0013] With the above-described structure, this invention features a positioning baffle mounted on the base of the overlock machine near the presser foot. During overlocking, the positioning baffle is positioned close to the presser foot, shortening the distance between the fabric overlocking point and the positioning baffle. This effectively reduces the possibility of wrinkles occurring during fabric movement and allows for timely detection and adjustment of any fabric shift below the stitches after wrinkles develop. This effectively prevents fabric shifting and ensures the accuracy of the overlocking process. Attached Figure Description

Detailed Implementation

[0020] See Figure 1-4 As shown, this utility model discloses an anti-deviation overlock machine, comprising a base 1 and a suspended overlock machine 2 mounted on the base 1. The suspended overlock machine 2 includes a body 3, with a presser foot 4 near the free end of the body 3. A horizontal moving component 5, moving along the length of the suspended overlock machine 2, is mounted on the base 1 near the presser foot 4. A moving bracket 6 is mounted on the horizontal moving component 5, and a positioning baffle 7 perpendicular to the suspended overlock machine 2 is mounted on the moving bracket 6. The positioning baffle is located on the base near the presser foot of the overlock machine. During overlocking, the positioning baffle moves close to the presser foot, shortening the distance between the overlocked area of ​​the fabric and the positioning baffle. This effectively reduces the possibility of wrinkles occurring during fabric movement and allows for timely detection and adjustment of the fabric below the stitches after wrinkles occur. This effectively prevents fabric deviation and ensures the accuracy of the overlocking process.

[0021] Meanwhile, the position of the positioning baffle can be adjusted by the horizontal moving component to match the overlock position of different fabrics.

[0022] In this embodiment, preferably, the horizontal movement component 5 includes a horizontal guide rail 5a mounted on a base 1 on one side of the body 3, a sliding seat 5b mounted on the horizontal guide rail 5a, and an adjusting screw 5c that cooperates with the sliding seat 5b mounted on the horizontal guide rail 5a via a bearing. A knob is provided at the end of the adjusting screw for adjusting the position of the sliding seat. In addition, for ease of operation, a servo motor and a corresponding control unit can be connected to the end of the adjusting screw to improve the convenience of operation.

[0023] More preferably, the movable support 6 includes a mounting suspension 6a disposed on the sliding seat 5b, a mounting plate 6b at the front end of the mounting suspension 6a, and a positioning baffle 7 disposed at the bottom of the mounting plate 6b. This structure, combined with a horizontal guide rail mounted on one side away from the worker's operating position, prevents the horizontal guide rail and the movable support from obstructing the worker during edge locking and avoids injury to the worker's hands from collisions with the movable support during use.

[0024] In this embodiment, the positioning baffle 7 includes several positioning plates 8, and an angle adjustment component 9 that cooperates with the positioning plates 8 is provided on the movable bracket 6. When hemming the round neck of the garment, the angle adjustment component 9 makes the positioning plates 8 cooperate to form a near-arc-shaped polygonal guide plate. By rotating the positioning plates through the angle adjustment component, the multiple positioning plates can be changed between straight guide lines and polygonal guides to meet the hemming needs of different parts of the garment.

[0025] In this embodiment, preferably, the positioning plate 8 includes two first baffles 8a, and two mounting holes 8b are symmetrically provided on the movable bracket 6. The first baffles 8a are hinged to the mounting holes 8b via a pivot, and a second baffle 8c is hinged to the free end of each first baffle 8a. The hinged arrangement of the second baffles with the first baffles ensures that the connection between the second baffles and the first baffles is maintained when the ends of the positioning baffles are bent, ensuring a smooth transition of the fabric between them and avoiding slight displacement of the fabric when it passes through due to unevenness.

[0026] More preferably, the angle adjustment component 9 includes a first screw 9a disposed at the upper end of the hinge shaft between the first baffle 8a and the second baffle 8c, and a first arc-shaped elongated hole 9b provided on the movable bracket 6 to cooperate with the first screw 9a, wherein the first arc-shaped elongated hole 9b is concentrically disposed with the mounting hole 8b.

[0027] A second screw 9c is provided at the free end of the second baffle 8c. A second arc-shaped elongated hole 9d is provided on the movable bracket 6 to cooperate with the second screw 9c. A third arc-shaped elongated hole 9e is provided at the end of the second arc-shaped elongated hole 9d away from the pressure foot 4. The second arc-shaped elongated hole 9d is concentric with the mounting hole 8b, and the third arc-shaped elongated hole 9e is concentric with one end of the first arc-shaped elongated hole 9b. Nuts 9f are provided on both the first screw 9a and the second screw 9c for clamping and fixing the movable bracket 6.

[0028] The first and second baffles rotate synchronously by cooperating with the first and second arc-shaped elongated holes. When the first baffle reaches the farthest end of the first arc-shaped elongated hole, the second baffle continues to rotate along the third arc-shaped elongated hole, so that the first and second baffles on both sides cooperate to form a polygonal guide plate.

[0029] During operation, the first and second baffles are rotated to the appropriate positions to form a straight guide plate or a polygonal guide plate, according to the shape of the fabric to be edged. The guide plates are then locked with nuts.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
