Description

Technical Field

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

[0002] In the textile production process, after the fabric is woven, it is often only a short length. To facilitate further processing, the fabric needs to be sewn together to form a longer piece of cloth. To improve the efficiency of sewing, a sewing machine is often used. During operation, the sewing machine needs to flatten the fabric, and the flattening effect directly determines the overall smoothness of the fabric after the sewing is completed.

[0003] However, in the existing technology, when sewing the fabric, it is necessary to press the fabric together. When sewing different fabrics, the width of the fabric is different, but the pressing length on the sewing machine is relatively fixed.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention features a sewing assembly. When the motor is started, it drives a take-up drum to rotate, which in turn drives a gear. The gear meshes with a toothed plate, causing it to roll. This rolling motion moves a mounting plate, which in turn moves the rotating take-up drum, winding up the pressure strip to a length matching the fabric width. Then, a cylinder is activated, pushing a moving plate. This moving plate moves a rectangular plate, which in turn moves a slider within a slide rail. The moving plate pushes the mounting plate and pressure strip together, pressing and fixing the fabric. Finally, a motor is started, driving a screw to rotate. Simultaneously, the screw moves an adjusting block, which in turn moves the sewing head. The sewing head then pulls the thread to sew the fabric ends together. This design allows for adjustment based on fabric width, ensuring the pressing length matches the fabric width and preventing wrinkles during sewing that could affect the seam.

[0014] This invention utilizes a stretching assembly. Fabric is placed on a placement rod, which is then pushed into the mounting groove. The roller is pulled, causing a rotating rod to move, which in turn moves a moving block. The moving block slides within a groove, compressing a spring. This compression causes the spring to deform and accumulate elastic force. The fabric head is then pulled through the roller. Releasing the roller releases the spring's compression force, pushing the roller back to its original position. This allows the roller to adhere to the fabric and roll it, pulling the fabric head in an S-shape around the stretching cylinder, stretching and straightening the fabric. Accumulated tension in the fabric head further pulls the fabric head to adhere to the top cylinder and fold it back, causing the fabric head to fold towards the placement plate. This method provides the advantages of limiting and clamping the fabric, rolling it, stretching and straightening it, and preventing wrinkles. Attached Figure Description

The placement rod 104 is placed in the two mounting slots 103. The PLC controller 105 is fixedly mounted on the corresponding upright plate 102.

[0028] like Figure 1As shown, in some embodiments, the stretching assembly 3 includes a roller pressing assembly and a folding assembly. The roller pressing assembly is mounted on the base assembly 1, and the folding assembly is mounted on the roller pressing assembly. The roller pressing assembly includes a rectangular frame 301, two sliding grooves 302, four springs 303, four moving blocks 304, two rotating rods 305, and two roller pressing cylinders 306. The rectangular frame 301 is fixedly installed on the top of the two upright plates 102. The two sliding grooves 302 are both formed on the rectangular frame 301. The four springs 303 are respectively fixedly installed in the two sliding grooves 302. The four moving blocks 304 are respectively slidably installed in the sliding grooves 302. The four springs 303 are respectively fixedly connected to the four moving blocks 304. The two rotating rods 305 are respectively rotatably installed on the four moving blocks 304. The two roller pressing cylinders 306 are respectively fixedly sleeved on the two rotating rods 305. More specifically, the fabric is sleeved on the placement rod 104, and the fabric is placed on the placement rod 104. The placement rod 104 is pushed into the mounting groove 103, at which point the roller cylinder 306 is pulled. The roller cylinder 306 drives the rotating rod 305 to move, and the rotating rod 305 drives the moving block 304 to move. The moving block 304 slides in the slide groove 302 and compresses the spring 303. The spring 303 is compressed and deforms, accumulating elastic force. At this time, the fabric head is pulled and passes through the roller cylinder 306. Then, the roller cylinder 306 is released, the spring 303 loses its compressive force and releases its elastic force. The force pushes the roller cylinder 306 back to its original position, causing the roller cylinder 306 to adhere to the fabric and roll it. This pulls the fabric head, causing the fabric to wrap around the stretching cylinder 309 in an S-shape, stretching and straightening the fabric. Accumulated force pulls the fabric head, causing the fabric to adhere to the top cylinder 312 and fold back, so that the fabric head folds towards the placement plate 201. The fabric head is then placed on the placement plate 201. This method has the advantages of limiting and clamping the fabric, rolling it, stretching and straightening it, and preventing wrinkles.

[0029] In some embodiments, the folding assembly includes two side plates 307, two connecting rods 308, two stretching cylinders 309, two support plates 310, a fixing rod 311, and a top cylinder 312. The two side plates 307 are fixedly installed on the top of the rectangular frame 301. The two connecting rods 308 are rotatably installed on the two side plates 307 respectively. The two stretching cylinders 309 are fixedly sleeved on the two connecting rods 308 respectively. The two support plates 310 are fixedly installed on the two side plates 307 respectively. The fixing rod 311 is rotatably installed on the two support plates 310. The top cylinder 312 is fixedly sleeved on the fixing rod 311. The placement plate 201 is fixedly installed on the two side plates 307.

[0030] In addition, four grooved plates 4 are fixedly installed on the bottom of the movable plate 205, and four sliding plates 5 are slidably installed on the four grooved plates 4 respectively. The four sliding plates 5 are fixedly connected to the four mounting plates 207 respectively.

[0031] Working principle:

[0032] Step 1: Roller stretching. Place the fabric onto the placement rod 104 and push the rod 104 into the mounting groove 103. At this time, pull the roller cylinder 306, which in turn moves the rotating rod 305. The rotating rod 305 then moves the moving block 304, which slides within the groove 302 and compresses the spring 303. The spring 303 deforms under pressure and accumulates elastic force. This pulls the fabric head through the roller cylinder 306. At this point, the roller cylinder 306 is released, the spring 303 loses its squeezing force and releases its elasticity to push the roller cylinder 306 back to its original position, so that the roller cylinder 306 is attached to the fabric and rolls the fabric, pulling the fabric head and wrapping the fabric in an S-shape around the stretching cylinder 309 to stretch and straighten the fabric, accumulating and pulling the fabric head to attach the fabric to the top cylinder 312 and fold it back, so that the fabric head is folded towards the placement plate 201 and placed on the placement plate 201. At this time, the roller pressing and stretching is completed.

[0033] Step Two: Press and sew. Start motor 2151. Motor 2151 drives take-up drum 211 to rotate. Take-up drum 211 drives gear 210 to rotate. When gear 210 rotates, it meshes with toothed plate 206, causing gear 210 to roll on toothed plate 206. When gear 210 rolls, it drives mounting plate 207 to move. Simultaneously, mounting plate 207 moves, driving the rotating take-up drum 211 to move. The rotating take-up drum 211 winds up the pressing strip 215, adjusting the pressing strip 215 to a length that matches the width of the fabric. At this time, cylinder 204 is activated. 04. Push the moving plate 205, which drives the rectangular plate 212 to move. The rectangular plate 212 drives the slider 214 to move. The slider 214 slides in the slide rail 213. The moving plate 205 pushes the mounting plate 207 and the pressure strip 215 to move, pressing and fixing the fabric. Start the motor 218, which drives the screw 217 to rotate. While the screw 217 rotates, it drives the adjusting block 219 to move. The adjusting block 219 drives the sewing head 220 to move. Start the sewing head 220, which pulls the thread to sew the fabric ends together.
