AI Technical Summary
The existing clothing fabric sewing positioning devices are mainly suitable for longitudinally moving clothing fabrics. They cannot effectively deal with the situation where the fabric needs to change the angle during the sewing process, resulting in wrinkles, reducing work efficiency and insufficient rotation angle.
A garment fabric sewing positioning device including a tiling mechanism and a rotating mechanism is designed. The tiling mechanism can open and position the clothing fabric through driving motors, transmission boxes and threaded rods; the rotation mechanism can achieve the fold-free rotation of the clothing fabric through the rotation ring, the rotation wheel and the rotation block, and the rotation angle is more accurate.
The device can accurately change the angle of the clothing fabric without creating creases, improve the efficiency and accuracy of the sewing process, and ensure the flatness and positioning accuracy of the clothing fabric.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabric sewing, in particular to a clothing fabric sewing positioning device. Background Art
[0002] Clothing is a general term for clothes, shoes, accessories, etc., mostly referring to clothes. The national standard defines clothing as: products that are sewn and worn on the human body for protection and decoration, also known as clothes.
[0003] Chinese Patent (Authorization Announcement No.: CN 216338319
[0004] U, authorization announcement date: 2022.04.19) proposes a sewing positioning device for polymer fiber clothing fabrics. By setting a positioning component, the clothing fabric can be positioned, and then the sliding component can be used to assist the movement of the positioning component, so as to determine the sewing route and avoid deviation during sewing. The problem that the existing device is prone to errors during sewing is solved. By setting a limiting component, one side of the sewing position of the clothing fabric can be limited, thereby playing a role in auxiliary positioning.
[0005] The existing sewing positioning device for clothing fabrics can generally only position the clothing fabrics that move longitudinally during sewing. However, in actual use, the angle of the clothing fabrics needs to be changed during sewing. However, since the clothing fabrics are relatively soft, wrinkles will occur when the clothing fabrics are rotated, which reduces work efficiency, and the rotation angle is not accurate enough. Therefore, we propose a sewing positioning device for clothing fabrics. Utility Model Content

[0024] The paving mechanism includes a driving motor 8 fixedly installed at the bottom of the inner wall of the avoidance groove 2, and four transmission boxes 9 are fixedly installed at the bottom of the inner wall of the avoidance groove 2. The four transmission boxes 9 are arranged at four corners.

The output end of the driving motor 8 is fixedly connected to the corresponding transmission end of the transmission box 9. The avoidance groove 2 is internally rotatably connected with two unidirectional threaded rods 11, and the thread directions of the two unidirectional threaded rods 11 are opposite. The two ends of the two unidirectional threaded rods 11 are respectively fixedly connected to the corresponding transmission ends of the transmission box 9.

Specifically, when it is necessary to sew the clothing fabric, the bottom cloth is placed on the top of the workbench 1, so that the bottom of the clothing fabric is in contact with the outside of the driving roller 10, the two unidirectional threaded rods 11 and the bidirectional threaded rod 12. At this time, the top cloth is placed at the required sewing position and can be sewn. When sewing, the driving motor 8 is started, and the output end of the driving motor 8 drives the driving roller 10 to rotate, and the clothing fabric is transmitted at a limited speed, so that the spacing of each stitch is consistent. At the same time, the two unidirectional threaded rods 11 rotate in the opposite direction to stretch the clothing fabric to both sides, so that the clothing fabric is flatter and convenient for sewing positioning and sewing. When the two unidirectional threaded rods 11 rotate, the bidirectional threaded rods 12 are driven to rotate, and the clothing fabric is further stretched to facilitate sewing.
[0025] The auxiliary rotating mechanism includes a first rotating frame 15 fixedly connected to the bottom of the sewing machine 4, the bottom of the first rotating frame 15 is rotatably connected to the second rotating frame 16, the bottom of the second rotating frame 16 is fixedly connected to two first sliding bars 17, the outsides of the two first sliding bars 17 are slidably connected to the second sliding bars 18, the bottoms of the two second sliding bars 18 are fixedly connected to the same fixing ring 19, the insides of the two first sliding bars 17 are provided with first tension springs 20, the tops of the two first tension springs 20 are fixedly connected to the tops of the inner walls of the corresponding first sliding bars 17, the bottoms of the two first tension springs 20 are fixedly connected to the bottoms of the inner walls of the corresponding second sliding bars 18, the outsides of the two second sliding bars 18 are rotatably connected to the rotating handles 21. Specifically, the rotating An adapting groove 26 is provided on the top of the movable block 7, and the fixing ring 19 is adapted to the adapting groove 26.

At this time, the rotating handle 21 is rotated around the sewing opening, so that the garment fabric can be rotated without creases, and the rotation angle is more precise. After the rotation, the driving motor 8 is started to comb and flatten the part outside the fixing ring 19, and then the rotating handle 21 is released, so that the fixing ring 19 rises under the tension of the two first tension springs 20, and the garment fabric can continue to be sewn.

The output end of the driving motor 8 drives the driving roller 10 to rotate, and the clothing fabric is transmitted at a limited speed, so that the spacing of each stitch is consistent. At the same time, the two unidirectional threaded rods 11 rotate in opposite directions to stretch the clothing fabric to both sides, so that the clothing fabric is flatter and convenient for sewing positioning and sewing. When the two unidirectional threaded rods 11 rotate, the bidirectional threaded rods 12 are driven to rotate, and the clothing fabric is further stretched to facilitate sewing. When the garment fabric is rotary sewn, one of the rotating handles 21 is held and moved downward, so that the two first tension springs 20 are stretched, and the two second slide bars 18 slide outside the corresponding two first slide bars 17, and the bottom of the fixed ring 19 contacts the garment fabric. At this time, the rotating handle 21 is rotated around the sewing opening to rotate the rotating ring 5 and the rotating block 7 at the same time, so that the garment fabric can be rotated without creases, and the rotation angle is more precise. After the rotation, the driving motor 8 is started to comb and flatten the part outside the fixed ring 19, and then the rotating handle 21 is released, so that the fixed ring 19 rises under the tension of the two first tension springs 20, and the garment fabric can continue to be sewn.
