Description

Technical Field

[0002] A quilting machine is a textile machine used to sew linear patterns on mattresses, bedspreads, quilts, etc. Quilting is the process of sewing interlayered textiles with long needles to fix the cotton wool inside. Taking quilts as an example, quilts are generally composed of two parts: the base material and the outer textile. In order to make the outer textile and the inner core of the quilt fit tightly and evenly, the outer textile and the inner core are sewn together in side-by-side straight lines or decorative patterns. This process of increasing beauty and practicality is called quilting.

[0003] During the use of a quilting machine, it is necessary to press the quilt with a presser foot. When the quilting machine is quilting quilts of different materials, different presser feet need to be replaced to avoid damage to the outer surface of the quilt by the presser foot. However, most of the current quilting machines usually use manual replacement when replacing the presser foot, which is cumbersome and affects production efficiency. Secondly, during the use of most quilting machines, it is necessary to manually fix the quilt, and when the quilting is completed, the quilt needs to be manually released before it can be taken out and the next quilt can be placed in for processing, which affects the processing efficiency.

The movement of the moving plate 303 drives the machine body 307 to move close to the position of the second motor 108, and the movement of the slide bar 302 drives the tooth plate 310 to move. At this time, the meshing of the tooth plate 310 and the first gear 111 drives the first gear 111 to rotate, and the rotation of the first gear 111 drives the transmission rod 110 to rotate, and the rotation of the transmission rod 110 drives the rotating drum 112 to rotate, and the rotation of the rotating drum 112 drives the worm 209 to rotate, and the rotation of the worm 209 drives the worm wheel 208 to rotate, and the rotation of the worm wheel 208 drives the rotating rod 207 to rotate, and the rotation of the rotating rod 207 drives the rotating claw 204 to rotate, so that the outer surface of the pressing wheel 205 contacts the upper surface of the quilt, and the quilt is limited;

[0055] Secondly, the No. 2 electric cylinder 309 is turned on to drive the machine body 307 to move, so that the machine body 307 is lowered to a suitable position to quilt the quilt. When the quilting is completed, the No. 2 motor 108 drives the mounting frame 301 back to its original position. At this time, the engagement of the tooth plate 310 and the No. 1 gear 111 drives the rotating claw 204 to rotate, so that the pressing wheel 205 and the outer surface of the quilt are not in contact, and the contact is limited to the quilt. The No. 1 motor 104 is turned on to drive the quilt to move, so that the processed quilt is moved out of the quilting area, and the unprocessed quilt is moved to the quilting area for processing;

[0056] Then, when the pressure plate 509 needs to be replaced, the No. 2 electric cylinder 309 is turned on to drive the body 307 to move to the top, and then the No. 5 motor 506 is turned on to drive the sixth bevel gear 507 to rotate, and the rotation of the sixth bevel gear 507 drives the fifth bevel gear 505 to rotate, and the rotation of the fifth bevel gear 505 drives the vertical rod 504 to rotate, and the rotation of the vertical rod 504 drives the rotating disk 503 to rotate, and the rotation of the rotating disk 503 drives the moving column 508 to make a circular motion, so as to adjust the position of the moving column 508. After the adjustment is completed, the electric telescopic rod 510 is turned on to push the moving column 508 downward, so that the moving column 508 moves to the bottom;

[0057] Finally, turn on the No. 4 motor 402 to drive the connecting rod 414 to rotate, and the rotation of the connecting rod 414 drives the No. 3 gear 415, the gear ring 416 and the No. 4 gear 418 to rotate. At this time, the No. 3 gear 415 and the No. 5 gear 420 are first meshed, and the No. 3 gear 415 drives the No. 5 gear 420 to rotate ninety degrees, and the rotation of the No. 5 gear 420 drives the fixed rod 419 to rotate, and the rotation of the fixed rod 419 drives the moving rod 403 to rotate, and the rotation of the moving rod 403 drives the cross plate 404 to rotate, so that the two ends of the cross plate 404 are respectively in contact with the upper outer surfaces of the two pressure plates 509. At this time, when the stopper 422 contacts the outer surface of the pressure plate 509, the stopper 422 is pushed to move inward, so that the pressure plate 509 is clamped at the two ends of the cross plate 404, and the pressure plate 509 is limited by the stopper 422 to prevent the pressure plate 509 from being separated during the rotation. When the clamping of the pressure plate 509 is completed;

[0058] The fourth gear 418 is meshed with the second gear 413, and the fourth gear 418 drives the second gear 413 to rotate 180 degrees. At this time, the rotation of the second gear 413 drives the rotating rod 411 to rotate, and the rotation of the rotating rod 411 drives the fourth bevel gear 412 to rotate, and the rotation of the fourth bevel gear 412 drives the third bevel gear 410 to rotate, and the rotation of the third bevel gear 410 drives the cross bar 407 to rotate, and the rotation of the cross bar 407 drives the rotating plate 408 to rotate, and the rotation of the rotating plate 408 drives the guide rod 409 to rotate semi-rotating. Circular motion, at this time, the semicircular motion can be decomposed into lateral movement and vertical movement. When the guide rod 409 moves horizontally, the guide rod 409 is slidably set inside the lifting plate 405. When the guide rod 409 moves vertically, the lifting plate 405 is driven to move vertically. At this time, the movement of the lifting plate 405 drives the moving rod 403 to move, and the movement of the moving rod 403 drives the horizontal plate 404 to move. At this time, the horizontal plate 404 moves downward. Through the downward movement of the horizontal plate 404, the two pressure plates 509 are separated from the moving column 508 and the mounting rod 311 respectively. When the separation is completed;

[0059] The third gear 415 and the fifth gear 420 are meshed again, and the third gear 415 drives the fifth gear 420 to rotate, and the rotation of the fifth gear 420 drives the cross plate 404 to rotate 180 degrees, so that the two pressure plates 509 are replaced. After the replacement is completed, the fourth gear 418 and the second gear 413 are meshed again, and the fourth gear 418 drives the second gear 413 to rotate 180 degrees. At this time, the rotation of the second gear 413 drives the cross plate 404 to move upward, so that the pressure plate 509 is installed with the moving column 508 and the installation rod 311 respectively. When the installation is completed, the gear ring 416 and the fifth gear 420 are meshed, driving the fifth gear 420 to reverse 90 degrees, so that the cross plate 404 returns to its original position, which is convenient for the next replacement.
