Description

Technical Field

[0001] This utility model relates to an overlocking device, specifically an overlocking device for garment processing, and belongs to the technical field of garment processing. Background Technology

[0002] As people's living standards improve, their demands for clothing are also increasing, with more and more styles and quantities of clothing available. The clothing manufacturing process generally involves several steps, including cutting, sewing, and ironing. To prevent the threads at the edges of the fabric from fraying during later use, the edges are usually finished with an overlock. This requires an overlock device, which sews a line around the edge of the fabric to wrap around it and prevent it from fraying. It also enhances the aesthetic appeal of the garment and is now widely used.

[0003] In existing methods of overlocking fabric, the edge of the fabric is typically placed below the sewing machine or similar device. The fabric passes under the sewing machine at a constant speed, while the machine sews the edge from above. During this process, to prevent wrinkles from forming at the fabric edge and affecting the overlocking effect, it is generally necessary to manually tighten both ends of the fabric to keep it taut before moving it at a constant speed. This requires workers to constantly pull the fabric, resulting in a significant workload. To address these issues, we provide an overlocking device for garment processing. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This overlocking device for garment processing, through the setting of components such as an extrusion plate and an elastic mechanism, and the power mechanism driving the fabric to move at a uniform speed, the overlocking machine body overlocks the fabric. During the movement of the fabric, the elastic mechanism provides an elastic force to the movable plate away from the overlocking machine body, so that when the extrusion plate moves close to the overlocking machine body, it will continuously apply a force to the fabric away from the overlocking machine body, thereby keeping the fabric in a taut state, achieving the effect of reducing manpower, thus solving the problem that existing workers need to constantly pull the fabric, resulting in a large workload.

[0014] 2. This garment processing overlocking device, through the setting of components such as a squeezing mechanism and a limiting mechanism, allows the first spring to provide a downward elastic force to the squeezing plate, enabling the squeezing plate to press down on the fabric. Lifting the pull plate upward can drive the squeezing plate upward away from the fabric, thereby releasing the pressure on the fabric. When the movable plate slides, the limiting plate limits the movable plate, and together with the movable block and the fixed rod, it prevents the movable plate from tilting, ensuring that the movable plate can only slide horizontally, thus increasing its stability.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1-5 The machine includes a flat plate 1 and a serger body 2 mounted on top of it. A transmission mechanism 3 is located at the lower part of the flat plate 1. A power mechanism 4 is located on one side of the flat plate 1 and on the other side of the flat plate 1 and the serger body 2. A pressing mechanism 6 is located at the lower part of the moving plate 5. A pressing plate 7 is located at the lower part of the pressing mechanism 6 and is located above the transmission mechanism 3. A limit mechanism 9 is located at one end of the moving plate 5 and an elastic mechanism 8 is located on one side of the limit mechanism 9. A support structure is also provided at the lower part of the flat plate 1 to separate the components on it from the ground and to protect the internal components. The power mechanism 4 can drive the fabric to move below the serger body 2 to serge the fabric. The transmission mechanism 3 is used to reduce the friction between the fabric and the flat plate 1 to facilitate the movement of the fabric. The pressing plate 7, in conjunction with the transmission mechanism 3, clamps the fabric in the middle. The elastic mechanism 8 provides the pressing plate 7 with an elastic force away from the serger body 2 to prevent the fabric from wrinkling during movement and to keep it in a taut state.

[0023] The transmission mechanism 3 includes a fixed plate 301, the upper surface of which is fixedly connected to the plate 1. A rotating shaft 302 is rotatably connected to the inner wall of the fixed plate 301. A conveyor belt 303 is provided on the outer surface of the rotating shaft 302. There are two rotating shafts 302, which are located on the inner sides of both ends of the conveyor belt 303. This allows the conveyor belt 303 to be kept taut. The rotating shafts 302 enable the conveyor belt 303 to rotate. When the fabric on the upper part of the conveyor belt 303 moves, it will drive the conveyor belt 303 to move, thereby facilitating the movement of the fabric. Compared with the existing method, this reduces the friction between the fabric and the plate 1.

[0024] The inner wall of the plate 1 is rotatably connected to a support shaft 304. The outer surface of the support shaft 304 is in contact with the conveyor belt 303. There are multiple support shafts 304, and the distance between each pair of support shafts 304 is less than the width of the extrusion plate 7. During the rotation of the conveyor belt 303, the support shaft 304 can support the conveyor belt 303 from the inside to prevent the middle part of the conveyor belt 303 from sinking downward.

[0025] The power mechanism 4 includes an electric motor 401. The output end of the electric motor 401 is connected to a drive roller 402. A rotating roller 403 is arranged above the drive roller 402. Support blocks fixed on the plate 1 are provided at both ends of the drive roller 402 and one end of the rotating roller 403 to support the drive roller 402 and the rotating roller 403. Pins are provided at the ends of the drive roller 402 and the rotating roller 403, which can rotate on the support blocks to achieve fixed-point rotation of the drive roller 402 and the rotating roller 403. The electric motor 401 can drive the drive roller 402 to rotate. When the fabric is located between the drive roller 402 and the rotating roller 403, it can drive the fabric to move.

[0026] The extrusion mechanism 6 includes a sliding rod 601. The outer surface of the sliding rod 601 is slidably connected to the movable plate 5. One end of the sliding rod 601 is fixedly connected to the extrusion plate 7, and the other end of the sliding rod 601 is connected to a pull plate 602. A first spring 603 is sleeved on the outside of the sliding rod 601. One end of the first spring 603 is fixedly connected to the extrusion plate 7, and the other end of the first spring 603 is fixedly connected to the movable plate 5. The first spring 603 can provide a downward elastic force to the extrusion plate 7, so that the extrusion plate 7 can press down on the fabric. Lifting the pull plate 602 upward can drive the extrusion plate 7 to move upward away from the fabric, thereby releasing the pressure on the fabric.

[0027] The elastic mechanism 8 includes two fixed blocks 801. The lower surface of the fixed blocks 801 is fixedly connected to the plate 1. A fixed rod 802 is fixedly connected between the two fixed blocks 801. A movable block 803 is slidably connected to the outer surface of the fixed rod 802. The upper surface of the movable block 803 is fixedly connected to the movable plate 5. A second spring 804 is connected to one side of the movable plate 5. The end of the second spring 804 away from the movable plate 5 is connected to the fixed block 801. The second spring 804 can give the movable plate 5 an elastic force away from the overlock machine body 2, so that when the extrusion plate 7 moves close to the overlock machine body 2, it will continuously give the fabric a force away from the overlock machine body 2, thereby keeping the fabric in a taut state.

[0028] A limiting plate 901 is installed on the upper surface of the plate 1. The inner wall of the limiting plate 901 is slidably connected to the movable plate 5. A limiting block 902 is connected to the end of the movable plate 5. When the movable plate 5 slides, the limiting plate 901 limits the movable plate 5. In conjunction with the movable block 803 and the fixed rod 802, the movable plate 5 is prevented from tilting and can only slide horizontally, thereby increasing its stability.

[0029] The electric motor 401 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

[0030] In use, the fabric edge is placed on the transmission mechanism 3, with one end inserted between the drive roller 402 and the rotating roller 403. The extrusion mechanism 6 pulls the extrusion plate 7 upward, so that the other end is inserted between the conveyor belt 303 and the extrusion plate 7. Then, the extrusion mechanism 6 drives the extrusion plate 7 downward to squeeze the fabric. During use, the power mechanism 4 drives the fabric to move at a uniform speed, and the overlock machine body 2 overlocks the fabric. During the movement of the fabric, the elastic mechanism 8 gives the movable plate 5 an elastic force away from the overlock machine body 2, so that when the extrusion plate 7 moves close to the overlock machine body 2, it will continuously give the fabric a force away from the overlock machine body 2, thus keeping the fabric in a taut state. It does not require manual pulling, only assistance from the side is needed, thus achieving the effect of reducing manpower.

[0031] When the movable plate 5 moves to a position close to the overlock machine body 2, the pressing mechanism 6 is pulled upward so that the pressing plate 7 stops pressing the fabric. Under the action of the elastic mechanism 8 and human force, the movable plate 5 moves to the side away from the overlock machine body 2. The above steps are repeated to perform long-distance overlocking.

[0032] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
