Description

Technical Field

[0001] This invention relates to the field of textile processing technology, specifically to a pattern sewing device for quilt production and processing. Background Technology

[0002] Sewing equipment mainly includes flatbed sewing machines, overlock sewing machines, coverstitch sewing machines, buttonhole machines, button attaching machines, knotting machines, embroidery machines, and so on. The main function of these machines is to complete processes such as sewing garment pieces together and joining edges. For example, Brother industrial sewing machines include various models such as single-needle flatbed sewing machines, chain lockstitch machines, knotting machines, buttonhole machines, button attaching machines, and automatic sewing machines. In addition, some companies, such as Bruce Industrial Sewing Machines, have introduced advanced technologies and equipment to ensure the stability and reliability of their products. In general, the selection of sewing equipment should be based on specific usage needs and budget.

[0003] Sewing is an indispensable part of garment manufacturing, primarily involving the stitching and covering of fabrics, leather, and other materials using a sewing machine. Depending on the machine and stitch used, there are many types of sewing techniques. These include straight seam, French seam, inside seam, outside seam, double-folded seam, rolled seam, and binding seam, among others. For example, a straight seam involves placing two layers of fabric right sides together and sewing a single line evenly along the wrong side, following the prescribed seam allowance. A French seam is further divided into two types: a topstitch (where the wrong sides of the garment are placed together, a topstitch is sewn 0.5cm from the edge, and then the seam allowance is trimmed to 0.3cm); and a topstitch (where the two garment pieces are turned inside out, right sides together, the seam is hand-stitched, and a second line is sewn 0.6cm along the edge). The choice of these techniques varies depending on the specific design and usage requirements.

[0004] However, in the existing technology for producing duvet covers with pleats, the sewing of the pleats is quite complicated and mainly involves manually folding the fabric for sewing. This process is inefficient, the pleat width is inconsistent, and the final product is of poor quality, failing to meet actual needs and customer requirements. Therefore, we have proposed a sewing device that improves the efficiency and quality of pleating during the sewing process. Summary of the Invention

A second lifting rod 213 is fixedly installed at the left end of the limiting piece 210. A circular groove 214 is fixedly provided at the inner end of the rotating housing 207. 14 passes through the inner end of the rotating housing 207 and extends to the left end of the rotating housing 207. The first lifting rod 212 and the second lifting rod 213 are movably installed in the inner end of the circular groove 214. The inner end of the workbench 1 is fixedly provided with a magnetic suction groove 215. The lower end of the inner end of the magnetic suction groove 215 is fixedly installed with a first magnet 216. The upper end of the first magnet 216 is movably installed with a second magnet 217. The upper end of the second magnet 217 is fixedly installed with a rocker 218. The rocker 218 is movably installed in the upper end of the workbench 1.

[0032] The trigger assembly 3 includes a pedal 313, which is positioned below the workbench 1. A first support rod 301 is hingedly mounted to the lower end of the pedal 313. A trigger cavity 302 is hingedly mounted to the lower end of the pedal 313. A metal insert rod 303 is fixedly mounted to the upper end of the inner end of the trigger cavity 302. A trigger block 304 is movably mounted to the inner end of the trigger cavity 302. A baffle 305 is fixedly mounted to the upper end of the trigger block 304. A slot 306 is fixedly provided to the inner end of the trigger block 304, extending through the inner end of the trigger block 304 and to the upper end of the baffle 305. The trigger block 304 extends through the inner end of the trigger cavity 302 and to the lower end of the trigger cavity 302. A first support rod 301 is hingedly mounted to the lower end of the trigger block 304. The first fixed block 307 has a second support rod 308 fixedly installed at its inner end. The outer end of the second support rod 308 is hinged to a first hinge block 309. A telescopic rod 310 is fixedly installed at the upper end of the first hinge block 309. A second hinge block 311 is fixedly installed at the upper end of the telescopic rod 310. A second spring 312 is movably installed at the outer end of the telescopic rod 310. The inner end of the second hinge block 311 is hinged to the lower end of the pedal 313. When pleating is required, the fabric is placed behind the presser foot 6 and then onto the rocker arm 218. The left hand presses down on the fabric on the worktable 1, while the right hand pulls the fabric behind it, tautning it and allowing it to pass through the rocker arm 218 so that the fabric does not adhere to the worktable 1. The first guide rod 212 passes through the gap between the fabric and the worktable 1. When the pedal 313 is stepped on, the sewing machine body 5 starts working. The presser foot 6 presses the fabric needle bar 7 to sew. At the same time, the metal insert 303 and the trigger block 304 in the trigger cavity 302 come into contact to close the circuit and start the motor 202. The output shaft of the motor 202 rotates, causing the rotating housing 207 to rotate together. When the inclined surfaces of the two second inclined groove protrusions 209 contact the inclined surface of the first inclined groove protrusion 206, the second inclined groove protrusions 209 overcome the force of the first spring 211 and move to the left. The first guide rod 212 and the second guide rod 213 extend out from the inside of the rotating housing 207 to the left under the push of the second inclined groove protrusions 209. At this time, with the rotation and extension of the first guide rod 212, the first guide rod 212 extends out from the inside of the rotating housing 207 to the left. 12. Moved between the fabric and workbench 1, the first lifting lever 212 rotates upward from below, carrying the fabric. The second lifting lever 213 is now above the fabric and presses it downward. At this time, the right hand slightly loosens to release the fabric. As the rotation continues, when the plane of the second inclined groove protrusion 209 is misaligned with the first inclined groove protrusion 206, the second inclined groove protrusion 209 is pushed to the right by the force of the first spring 211. The first lifting lever 212 and the second lifting lever 213 retract to the right. Before retraction, the left hand presses down on the already formed pleats and pushes the fabric forward to sew the pleats. The first support rod 301 provides support to make the structure more stable. The metal insert 303 and the trigger block 304 are made of metal with good conductivity and are electrically connected to the motor 202.The sewing machine body 5 operates simultaneously with the motor 202. The baffle 305 limits the trigger block 304, preventing it from disengaging from the trigger cavity 302. The second support rod 308 provides support while facilitating the installation and activation of the trigger assembly 3. The pedal 313 controls the kinetic energy output of the sewing machine body 5 and also triggers the motor 202 to operate.

[0033] The lower end of the workbench 1 is fixedly connected to a support leg 4, which is symmetrically distributed on the left and right. The two ends of the second support rod 308 and the first support rod 301 are fixedly connected between the two support legs 4. The upper end of the workbench 1 is fixedly installed with a sewing machine body 5. The lower end of the sewing machine body 5 is provided with a presser foot 6 and a needle bar 7. The support legs 4 can provide support and stability.

[0034] Working principle: When pleating is required, the fabric is placed behind the presser foot 6 on the rocker arm 218. The left hand presses down on the fabric on the worktable 1, while the right hand pulls the fabric behind, tautning it and allowing it to pass through the rocker arm 218 without touching the worktable 1. This facilitates the first take-up bar 212 passing through the gap between the fabric and the worktable 1. When the pedal 313 is pressed, the sewing machine body 5 starts working. The presser foot 6 presses down on the fabric needle bar 7 to sew, simultaneously triggering the metal insert 303 and trigger block 304 in the trigger cavity 302 to contact, closing the circuit and starting the motor 202. The output shaft of the motor 202 rotates, causing the rotating housing 207 to rotate as well. When the inclined surfaces of the two second inclined groove protrusions 209 contact the inclined surface of the first inclined groove protrusion 206, the second inclined groove protrusions 209... Overcoming the force of the first spring 211, the first and second rods 212 and 213 extend out from the inside of the rotating housing 207 to the left under the push of the second inclined groove protrusion 209. At this time, as the rotation and extension occur, the first rod 212 moves between the fabric and the worktable 1. With the counterclockwise rotation, the first rod 212 rotates upward from below with the fabric. The second rod 213 is now above the fabric and presses the fabric downward. At this time, the right hand is slightly loosened to release the fabric. As the rotation occurs, when the plane of the second inclined groove protrusion 209 is misaligned with the first inclined groove protrusion 206, the second inclined groove protrusion 209 is pushed to the right under the force of the first spring 211. The first rod 212 and the second rod 213 retract to the right. Before retraction, the left hand presses down the pleats that have already been made and pushes the fabric forward to sew the pleats.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
