DETAILED DESCRIPTION
[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0027] Reference Figure 1-5 , a wrinkle-proof device for a garment sewing machine comprises a sewing machine body 1, a mounting block 2 is fixedly connected to one side of the sewing machine body 1, an anti-wrinkle device 3 is rotatably connected to the outer surface of the mounting block 2, the anti-wrinkle device 3 comprises a rotating plate 4, two limiting rods 5 are inserted on one side of the rotating plate 4, a connecting plate 6 is fixedly connected to the bottom of the limiting rod 5, a through slot 7 is respectively provided on both sides of the connecting plate 6, a plurality of pressure rollers 8 are rotatably connected to the inside of each through slot 7, a lifting rod 9 is rotatably connected to one side of the connecting plate 6, and the lifting rod 9 is inserted on one side of the rotating plate 4. The specific structure and working principle of the sewing machine body 1 are existing mature technologies and will not be repeated here.
[0028] An annular rotating groove 201 is formed on the outer surface of the mounting block 2, and a collar 401 is fixedly connected to the interior of the rotating plate 4. The shape of the collar 401 matches the shape of the rotating groove 201, and the collar 401 is rotatably connected to the interior of the rotating groove 201. Through the cooperation between the collar 401 and the rotating groove 201, the entire anti-wrinkle device 3 can be rotated. When the sewing direction of the garment fabric changes, the fabric is pulled along the sewing direction. Due to the friction between the fabric and the pressure roller 8, the entire anti-wrinkle device 3 is driven to rotate, so that the rotation direction of the pressure roller 8 matches the pulling direction of the fabric, thereby playing an anti-wrinkle role when the fabric is sewn in different directions.
[0029] The rotating plate 4 is a circular plate-shaped structure. Two insertion holes 402 and a threaded hole 403 are provided on one side of the rotating plate 4 . The two insertion holes 402 are symmetrically arranged on both sides of the threaded hole 403 .
[0030] The outer surface of the limiting rod 5 is adapted to the inner surface of the insertion hole 402 . The outer surfaces of the two limiting rods 5 are respectively inserted into the inner surfaces of the two insertion holes 402 . The top of each limiting rod 5 is fixedly connected to a limiting block 501 .
[0031] The outer surface of each limiting rod 5 is sleeved with a spring 502, and the upper and lower sides of the spring 502 are respectively in contact with the bottom of the rotating plate 4 and the top of the connecting plate 6. The elastic force of the spring 502 is relatively small, and it only serves to press the connecting plate 6 to slightly increase the pressure of the pressing roller 8 on the fabric, and will not cause the pressing roller 8 to have a large pressure and friction on the clothing fabric, making the fabric difficult to pull.
[0032] A rotating hole 601 is opened on one side of the connecting plate 6, and a rotating block 901 is fixedly connected to the bottom of the lifting rod 9. The outer surface of the rotating block 901 is adapted to the inner surface of the rotating hole 601, and the outer surface of the rotating block 901 is rotatably connected to the inner surface of the rotating hole 601.
[0033] The upper side of the lifting rod 9 is inserted into the inside of the threaded hole 403, and the top of the lifting rod 9 is fixedly connected to the handle 902. The outer surface of the lower side of the lifting rod 9 is provided with a thread that matches the threaded hole 403. When the anti-wrinkle device 3 is not needed, the lifting rod 9 is pulled by the handle 902 to pull the connecting plate 6 upward until the threaded part on the lifting rod 9 is close to the inside of the threaded hole 403. The lifting rod 9 is rotated so that its threaded part is connected to the internal thread of the threaded hole 403. At this time, the connecting plate 6 will be pulled and kept high, without affecting the normal movement of the clothing fabric on the surface of the sewing machine body 1.
[0034] Two through slots 7 are symmetrically opened on both sides of the connecting plate 6 . A plurality of rotating shaft holes 701 are opened on both sides of each through slot 7 . The plurality of rotating shaft holes 701 are arranged in a linear array.
[0035] Several pressure rollers 8 are distributed in a linear array, and the bottom of the pressure roller 8 contacts the upper surface of one side of the sewing machine body 1. A rotating shaft 801 is fixedly connected to both sides of each pressure roller 8. The rotatable pressure roller 8 can reduce the friction with the fabric during the pulling process, avoiding excessive squeezing of the fabric, making it inconvenient to pull, and causing damage to the fabric.
[0036] The outer surface of the rotating shaft 801 is adapted to the inner surface of the rotating shaft hole 701, and the outer surface of the rotating shaft 801 is rotatably connected to the inner surface of the rotating shaft hole 701. The fabric is placed from one side of the connecting plate 6 to the bottom of the pressure roller 8. The pressure roller 8 presses the fabric downward through the elastic force of the spring 502. The fabric is manually pulled toward the side of the connecting plate 6 and sewing begins. During the pulling process, the fabric will remain taut and smooth. Even if you let go and stop pulling during this process, the fabric will remain smooth and will not shrink due to the downward pressure of multiple pressure rollers 8, thereby achieving the purpose of preventing wrinkles during the sewing process.
[0037] In the present invention, the fabric is placed under the pressure roller 8 from one side of the connecting plate 6, and the pressure roller 8 presses the fabric downward by the elastic force of the spring 502. The fabric is manually pulled toward one side of the connecting plate 6 and sewing begins. During the pulling process, the fabric will remain taut and smooth. Even if the pulling is stopped during this process, the fabric will remain smooth and will not shrink due to the downward pressure of multiple pressure rollers 8, thereby achieving the purpose of preventing wrinkles during the sewing process. The entire anti-wrinkle device 3 can be rotated through the cooperation between the ring 401 and the rotating groove 201. When the sewing direction of the clothing fabric changes, the fabric is pulled along the direction of the sewing. Due to the friction between the fabric and the pressure roller 8, the entire anti-wrinkle device 3 will be driven to rotate, so that the rotation direction of the pressure roller 8 is adapted to the pulling direction of the fabric, thereby playing an anti-wrinkle role when the fabric is sewn in different directions.
[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
