Description

Technical Field

[0001] The utility model relates to the technical field of fabric overlocking, in particular to a textile fabric overlocking machine. Background Art

[0002] Overlock is a term in the clothing industry. In the process of producing clothing, since the materials used, such as polyester, are generally synthetic fibers with relatively hard texture, after cutting, the silk threads at the edges of the cut clothes will spread out due to their high hardness, so overlocking is required. A special overlocking machine is used to overlock a circle of edges at the edges to prevent the silk threads in the fabric from spreading out.

[0003] General overlock machines are universal and are not classified according to the thickness and width of the fabric. Therefore, it is difficult to press the fabric tightly during overlocking. As a result, the silk thread will not be pulled tightly, resulting in looseness, bubbles and other undesirable phenomena. Utility Model Content

[0024] The bottom of the right top plate 102 of the overlocking device 103 is fixedly connected with an elastic component 2, the bottom of the elastic component 2 is rotatably connected with a pressing wheel 201, the side edge of the surface of the bottom plate 1 is fixedly connected with a side plate 202, the side wall of the side plate 202 is threadedly connected with a threaded bolt 203, and the end of the threaded bolt 203 is rotatably connected with an L-shaped plate 204;

[0025] The surface of the L-shaped plate 204 is slidably connected to a sliding column 205, and the bottom end of the sliding column 205 is fixedly connected to a pressing plate 206;

[0026] The top of the sliding column 205 is fixedly connected to the circular plate 207, and a first spring 208 is fixedly connected between the circular plate 207 and the L-shaped plate 204, and the first spring 208 is located outside the sliding column 205;

[0027] It should be noted that: when overlocking, the elastic force of the elastic component 2 is used to press the pressing wheel 201 on the side of the fabric to be overlocked, and then the threaded bolt 203 on the side wall of the side plate 202 is rotated, and the threaded bolt 203 drives the L-shaped plate 204 at its bottom to slide, and the inner wall of the L-shaped plate 204 is pressed against the other side of the fabric, and then the sliding column 205 is pulled upward, and the first spring 208 located between the circular plate 207 and the L-shaped plate 204 is stretched, and the fabric is placed on the sliding column 20 5, and then release the sliding column 205. Under the elastic force of the first spring 208, the sliding column 205 drives the pressing plate 206 to press down, pressing the cloth tightly against the surface of the bottom plate 1. The L-shaped plate 204 limits one side of the cloth, so when the cloth is pulled on the surface of the bottom plate 1, the cloth will not deviate sideways, and the cloth will not wrinkle due to the flattening effect of the pressing wheel 201 and the pressing plate 206, which is conducive to the hemming of the cloth by the hemming device 103.

[0028] Reference Figure 1-3The elastic component 2 includes a sleeve 3, a telescopic column 301 and a second spring 302. The sleeve 3 is fixedly mounted on the bottom of the top plate 102. The inner wall of the sleeve 3 is slidably connected with the telescopic column 301, and the telescopic column 301 is rotatably connected to the pressure wheel 201. The second spring 302 is fixedly connected between the telescopic column 301 and the sleeve 3;

[0029] A frame 303 is fixedly connected to the surface of the bottom plate 1 on the right side of the top plate 102, and sliding blocks 304 are slidably connected to both sides of the inner wall of the frame 303;

[0030] A sticky roller 305 is rotatably connected between the sliding blocks 304, and a third spring 306 is fixedly connected between the sliding blocks 304 and the frame 303;

[0031] It should be noted that: the telescopic column 301 is pressed down under the action of the second spring 302 in the inner cavity of the sleeve 3, and the cloth is squeezed onto the surface of the bottom plate 1 by the pressing wheel 201 to facilitate the subsequent flanging. Before the cloth is flanged, the cloth is passed under the sticking roller 305 in the inner cavity of the frame 303. At this time, the sticking roller 305 slides down with the sliding block 304 under the elastic force of the third spring 306. The sticking roller 305 is pressed against the surface of the cloth, and as the cloth slides, the sticking roller 305 rolls to stick the wire remaining on the surface of the cloth to avoid affecting the subsequent flanging.

[0032] Reference Figure 1-3 The side wall of the bottom plate 1 is fixedly connected with a connecting plate 307, the side wall of the connecting plate 307 is fixedly connected with a servo motor, and the side wall of the servo motor is fixedly connected with a rotating shaft 308;

[0033] A cloth rolling roller 309 is fixedly connected to the side wall of the rotating shaft 308, and the side wall of the bottom plate 1 located on one side of the cloth rolling roller 309 is arranged in an arc shape;

[0034] It should be noted that: when the cloth is hemmed, one side of the cloth is wound around the side wall of the cloth roller 309, and then the servo motor on the side wall of the connecting plate 307 is turned on. The servo motor drives the rotating shaft 308 and the cloth roller 309 to rotate, and the cloth roller 309 rotates to tighten the cloth, thereby facilitating the hemming of the cloth on the surface of the base plate 1, without the need for manual intervention, thus saving manpower.

[0035] Operation method: Before the fabric is overlocked, the fabric is passed under the sticking roller 305 in the inner cavity of the frame 303. At this time, the sticking roller 305 slides down following the sliding block 304 under the elastic force of the third spring 306, and the sticking roller 305 is pressed against the surface of the fabric. As the fabric slides, the sticking roller 305 rolls to stick the wire remaining on the surface of the fabric to avoid affecting the subsequent overlocking. When overlocking, the telescopic column 301 is pressed down under the action of the second spring 302 in the inner cavity of the sleeve 3, so that the pressing wheel 201 is pressed against the side of the fabric that needs to be overlocked, and then the threaded bolt 203 on the side wall of the side plate 202 is rotated, and the threaded bolt 203 drives the L-shaped plate 204 at its bottom to slide, and the L-shaped plate 20 4 The inner wall is squeezed on the other side of the cloth, and then the sliding column 205 is pulled up. At this time, the first spring 208 located between the circular plate 207 and the L-shaped plate 204 is stretched, and the cloth is placed under the pressing plate 206 at the bottom of the sliding column 205. Then the sliding column 205 is released. Under the elastic force of the first spring 208, the sliding column 205 drives the pressing plate 206 to press down, pressing the cloth tightly against the surface of the bottom plate 1, and the L-shaped plate 204 limits one side of the cloth, so when the cloth is pulled on the surface of the bottom plate 1, the cloth will not deviate sideways, and the cloth will not wrinkle due to the flattening effect of the pressing wheel 201 and the pressing plate 206, which is conducive to the hemming of the cloth by the hemming device 103;

[0036] When the cloth is hemmed, one side of the cloth is wound around the side wall of the cloth roller 309, and then the servo motor on the side wall of the connecting plate 307 is turned on. The servo motor drives the rotating shaft 308 and the cloth roller 309 to rotate, and the cloth roller 309 rotates to tighten the cloth, thereby facilitating the hemming of the cloth on the surface of the bottom plate 1, without the need for manual intervention, thus saving manpower.
