Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to an automated sewing device for fabric. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. Generally, a sewing machine consists of four parts: the machine head, the base, the transmission, and accessories. Sewing machines are classified into three categories according to their use: household machines, various industrial machines, and various service industry machines. Modern clothing styles are diverse, and hooded garments are popular due to their strong sense of fashion and windproof and warm properties. When making hooded garments, webbing is often sewn onto the joint between the garment body and the hood to form a back collar strip (also called a neckline strip). This webbing can cover the rough fabric threads at the joint, reducing neck discomfort and improving the aesthetics of the joint. The hood joint is usually sewn using a sewing machine.

[0003] In the process of sewing the seams of clothing and hats using existing sewing machines, the fabric is usually folded and placed under the needle. During the sewing process, the fabric is pushed backward by hand to sew it together. However, the degree of automation is low, the sewing process is cumbersome, and the sewing efficiency is low.

[0004] Therefore, it is necessary to invent an automated sewing device for fabrics to solve the above problems. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 5 An automated fabric sewing device is shown, comprising an equipment bracket 1, an mounting frame 11 fixedly connected to the upper end of the equipment bracket 1, a mounting plate 2 that can slide left and right on the upper side of the mounting frame 11, a sewing machine body 21 fixedly mounted on the upper surface of the mounting plate 2, a synchronizer 22 fixedly mounted on the right end of the sewing machine body 21, a pull tube 25 engaged at the front side of the needle in the sewing machine body 21, and a transmission assembly provided at the rear side of the needle in the sewing machine body 21. The transmission assembly includes an equipment box 3, a second motor 31, a first transmission wheel 32, a second transmission wheel 33, a first conveyor belt 34, a connecting shaft 35, a third transmission wheel 36, a connecting plate 37, a transmission roller 38, a fourth transmission wheel 39, and a second conveyor belt 310.

[0034] The pull tube 25 has a buckle on its lower side, and the surface of the mounting plate 2 has a slot. The buckle is snapped into the slot to fix the pull tube 25 to the surface of the mounting plate 2. The pull tube 25 is available in different styles. The appropriate pull tube 25 is selected according to the sewing style. The pull tube 25 can be disassembled during the overall sewing of the garment to improve ease of use. During use, after the fabric strip is passed through the pull tube 25, it passes under the transmission roller 38. At this time, the second motor 31 drives the transmission roller 38 to rotate, which automatically moves the fabric strip to the rear. The sewing speed is controlled by the synchronizer 22 to synchronize the sewing speed with the fabric strip movement speed, so as to realize automatic sewing of the fabric strip and improve the sewing quality.

[0035] See Figure 2 , Figure 4 and Figure 5The equipment box 3 is fixedly connected to the rear surface of the sewing machine body 21 near the left end. The second motor 31 is fixedly installed on the right side surface of the equipment box 3. The first transmission wheel 32 is rotatably connected to the inner wall of the equipment box 3 near the upper side. The right end of the first transmission wheel 32 is fixedly connected to the output end of the second motor 31. The second transmission wheel 33 is rotatably connected to the inner wall of the equipment box 3 near the lower side. The first conveyor belt 34 is connected to the first transmission wheel 32 and the second transmission wheel 33. The left end of the second transmission wheel 33 is fixedly connected to the connecting shaft 35. The connecting shaft 35 is rotatably connected to the side wall of the equipment box 3. The third transmission wheel 36 is fixedly connected to the left end of the connecting shaft 35. The connecting plate 37 is rotatably connected to the lower end of the right side surface of the equipment box 3. The transmission roller 38 is rotatably connected to the lower end of the connecting plate 37. The fourth transmission wheel 39 is fixedly connected to the left end of the transmission roller 38. The second conveyor belt 310 is connected to the third transmission wheel 36 and the fourth transmission wheel 39.

[0036] Specifically, the output of the second motor 31 drives the first transmission wheel 32 to rotate. The first transmission wheel 32, in conjunction with the first conveyor belt 34, drives the second transmission wheel 33 to rotate. The second transmission wheel 33, through the connecting shaft 35, drives the third transmission wheel 36 to rotate. The third transmission wheel 36, in conjunction with the second conveyor belt 310, drives the fourth transmission wheel 39 to rotate, which in turn drives the transmission roller 38 to rotate, pulling the fabric strip backward.

[0037] In addition, the upper end of the connecting plate 37 can rotate around the lower end of the equipment box 3 and can be suspended at different heights to adjust the height of the transmission roller 38. During the feeding process, the transmission roller 38 is first rotated upward to raise its position. Then, the cloth strip is moved to the lower side of the transmission roller 38, and then the transmission roller 38 is rotated downward to press it against the surface of the cloth strip.

[0038] See Figure 1 , Figure 3 and Figure 6 A precision screw 12 is rotatably connected to the middle position between the inner walls of the left and right sides of the mounting bracket 11. Linear guide rails 13 are fixedly connected to the inner walls of the left and right sides of the mounting bracket 11 at the positions before and after the precision screw 12. A first motor 14 is fixedly installed at the left end of the mounting bracket 11. The output end of the first motor 14 is fixedly connected to the left end of the precision screw 12. A transmission block 23 is fixedly connected to the middle position of the lower surface of the mounting plate 2. Two sets of linear bearings 24 are fixedly connected to the lower surface of the mounting plate 2 at the positions before and after the transmission block 23. The transmission block 23 is threadedly connected to the precision screw 12, and the linear bearings 24 are slidably connected to the linear guide rails 13.

[0039] Meanwhile, during use, the first motor 14 drives the precision screw 12 to rotate. As the precision screw 12 rotates, it drives the transmission block 23 to slide left and right on its surface, thereby causing the mounting plate 2 to slide left and right on the upper side of the mounting frame 11. The linear bearing 24 cooperates with the linear guide rail 13 to improve the smoothness of the sliding of the mounting plate 2, making it easy to adjust the left and right position of the mounting plate 2. This, in turn, makes it easy to adjust the left and right position of the sewing machine body 21, so that it can adapt to different body positions of the user. It can also be adjusted at any time during use, effectively improving the comfort and convenience of use.

[0040] The working principle of this utility model is as follows: By using the pull tube 25 to fold the fabric strip into the shape to be sewn, the second motor 31 drives the transmission roller 38 to rotate, pulling the rear end of the fabric strip to move backward. At the same time, the sewing speed of the sewing machine body 21 is controlled by the synchronizer 22 to synchronize with the movement of the fabric strip, thereby realizing automatic sewing of the fabric strip and improving sewing efficiency and quality. Meanwhile, the first motor 14 drives the mounting plate 2 to slide left and right on the surface of the mounting frame 11, thereby adjusting the left and right position of the sewing machine body 21 on the surface of the mounting plate 2. During use, the position of the sewing machine body 21 can be adjusted at any time according to changes in body position, improving user comfort and ease of use.
