Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically to a bag opening machine slitting frame that facilitates adjustable spacing. Background Technology

[0002] A pocket opening machine is a professional sewing device used to cut and sew pocket openings on garments. Its main body is a large flat platform equipped with a servo drive system, a laser cutting system, a slitting device, and a sewing machine head. The servo drive system precisely moves the fabric clamping mechanism on the platform. The laser cutting system achieves non-contact cutting of the fabric, resulting in clean, burr-free cuts. The slitting device separates the laser-cut fabric into the shape of the pocket opening. Finally, the sewing machine head sews the opening onto the garment, thus shaping the pocket. The slitting device is typically fixedly installed on the pocket opening machine. On the large flatbed of the machine, directly below the laser cutting system, the servo drive system moves the fabric to the position of the slitting device. The slitting device then fixes the fabric, which is then cut by the laser cutting system. After cutting, the slitting device separates the two sides of the opening in the fabric and folds the fabric at the opening. Then, in conjunction with the servo drive system, the template is moved so that the cut fabric is sewn by the sewing machine head to form a fabric with pockets. This process is highly automated, has good slitting stability, and produces consistently high-quality fabric with pockets.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: After the existing fabric is laser-cut, it needs to be lowered by a slitting frame and inserted into the opening formed by the laser cut to stretch the fabric and press the edges of the cut fabric downwards. In this way, the two fabric pulling frames of the slitting device pull the fabric and separate it to form a pocket opening. The existing slitting frame has a square block structure, and the square block corresponding to the width of the pocket opening needs to be selected according to the width of the fabric pocket opening. When adjusting the fabric pocket opening, it is often necessary to stop the machine and disassemble the entire slitting frame to replace the square block. The adjustment is very cumbersome and inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a bag-opening machine slitting frame that is easy to adjust the opening width and has good adaptability for adjusting the spacing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bag-opening machine slitting frame that facilitates adjustable spacing, comprising a connecting rod detachably connected to the rear plate of the slitting device and a second forward-pushing cylinder detachably mounted on the rear plate. The end of the second forward-pushing cylinder is provided with a forward-moving plate with a slide rail on the front. A sliding frame is slidably mounted on the slide rail of the forward-moving plate. A descending plate is fixedly connected to the bottom of the sliding frame. A downward-pushing cylinder with its bottom end fixedly connected to the top surface of the descending plate is also mounted on the forward-moving plate. A second downward-pushing cylinder is also provided through the descending plate. An opening pressure frame is fixedly connected to the bottom end of the second downward-pushing cylinder.

[0006] A further improvement is that the bottom surface of the descending plate is also provided with a positioning rod that penetrates the descending plate, and the bottom end of the positioning rod is fixedly connected to the top surface of the opening pressure frame.

[0007] A further improvement is that the open pressure frame includes a top plate fixedly connected to the bottom end of the second push cylinder and four extension blocks symmetrically distributed on the bottom edge of the top plate and detachably mounted on the bottom surface of the top plate. A crossbar is provided between two of the extension blocks, and two symmetrically distributed pressing devices are slidably mounted on the crossbar.

[0008] A further improvement is that the tablet pressing device includes a sliding plate slidably mounted on a crossbar and a tablet that is detachably mounted on the side of the sliding plate and extends downwards via bolts.

[0009] A further improvement is that the sliding plate has an integrally formed threaded hole perpendicular to the crossbar, and a fastener, which is a stud, is engaged in the threaded hole.

[0010] A further improvement is that a rubber block is provided on the end of the stud near the crossbar.

[0011] A further improvement is that a handle is provided on the end of the stud away from the crossbar.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When this utility model is used, after the fabric is laser-cut, the second push cylinder can be used to push the opening pressure frame downward, thereby causing the top plate of the opening frame to drive the pressure plates of the two pressure plates to move downward, thus pressing down the fabric to be opened, so that the fabric is pressed open along the opening position. After the specifications of the opening fabric are changed in the bag opening machine, the distance between the two pressure plates needs to be adjusted. At this time, the fastener can be quickly tightened to make the fastener untighten, so that the fastener loses its contact with the crossbar. Then, the sliding plate of the pressure plate device can be manually pulled to move laterally along the crossbar, thereby changing the distance between the two pressure plates. After adjusting to a suitable width, the fastener can be tightened again, so that the fastener abuts against the crossbar and squeezes the crossbar to achieve the effect of fixing the sliding plate. There is no need to disassemble the entire dividing frame for adjustment, making it simpler and more convenient to adjust the pocket adaptation width of the dividing frame.

Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figure 1-5As shown, the technical solution adopted in this specific embodiment is: a bag-opening machine slitting frame that facilitates adjustable spacing, including a connecting rod 442 detachably connected to the rear plate 41 of the slitting device and a second forward-pushing cylinder 441 detachably mounted on the rear plate 41. The end of the second forward-pushing cylinder 441 is provided with a forward-moving plate 443 with a slide rail on its front. A sliding frame 444 is slidably mounted on the slide rail of the forward-moving plate 443. A descending plate 446 is fixedly connected to the bottom of the sliding frame 444. A downward-pushing cylinder 445 is also mounted on the forward-moving plate 443, with its bottom end fixedly connected to the top surface of the descending plate 446. The descending plate 446 is also... A second downward-pushing cylinder 447 is provided, and an open pressure frame 448 is fixedly connected to the bottom end of the second downward-pushing cylinder 447. The open pressure frame 448 includes a top plate 31 fixedly connected to the bottom end of the second downward-pushing cylinder 447 and four detachable extension blocks 32 symmetrically distributed on the bottom edge of the top plate 31. A crossbar 34 is provided between two extension blocks 32. Two symmetrically distributed pressing devices are slidably mounted on the crossbar 34. The pressing device includes a sliding plate 33 slidably mounted on the crossbar 34 and a pressing plate 35 detachably mounted on the side of the sliding plate 33 and extending downward by bolts. At this time, the fabric is placed on the slitting device, and the fabric is cut at the designated position using a laser cutter. Then, the position of the forward moving plate 443 can be adjusted by the second forward pushing cylinder 441 of the slitting frame, and the forward moving plate 443 is made to move along a straight path by the connecting rod 442. When the opening pressure frame 448 moves to the position of the fabric opening, the second forward pushing cylinder 441 stops running. At this time, the second downward pushing cylinder 447 can push the opening pressure frame 448 downward, which in turn causes the top plate 31 of the opening pressure frame 448 to drive the pressure plates 35 of the two pressure plate devices to move downward, thereby opening the fabric. Pressing down the fabric at the opening causes it to open along the opening. After changing the fabric specifications on the bag opening machine, the distance between the two pressing devices needs to be adjusted. At this time, the sliding plate 33 of one of the pressing devices can be manually moved laterally along the crossbar 34, thereby causing the sliding plate 33 of the pressing device to move the pressing plate 35 along the crossbar 34. This makes the distance between the pressing plates 35 of the two pressing devices larger or smaller. After adjusting to a suitable width, it can be used without disassembling the entire dividing frame for adjustment. Adjusting the pocket fit width of the dividing frame is simpler and more convenient. The bottom surface of the descending plate 446 is also provided with a positioning rod 449 that penetrates the descending plate 446. The bottom end of the positioning rod 449 is fixedly connected to the top surface of the open pressure frame 448, which helps to make the descending trajectory of the open pressure frame 448 more straight when it descends, and avoids skewness. The sliding plate 33 has an integrally formed threaded hole perpendicular to the crossbar 34. A fastener 36 is engaged in the threaded hole. The fastener 36 is a stud 362. During use, by screwing the fastener 36 into the threaded hole, the end of the fastener 36 abuts against the crossbar 34, generating strong friction to prevent the sliding plate 33 from sliding abnormally. This fixes the sliding plate 33 and ensures the accurate width of the opening. When adjusting, simply unscrew the fastener 36 to allow the sliding plate 33 to slide normally and adjust the opening width. This makes adjusting the distance between the two sliding plates 33 simpler and more convenient, and provides a better fixing effect for the sliding plates 33. A rubber block 363 is provided on the end of the stud 362 near the crossbar 34, which helps to increase the frictional resistance between the end of the stud 362 and the crossbar 34 after it is screwed in, further preventing the sliding plate 33 from shifting laterally and reducing the squeezing damage to the crossbar 34. A handle 361 is provided on the end of the stud 362 away from the crossbar 34, which makes it easier and less strenuous to unscrew the stud 362.

[0017] The working principle of this utility model is as follows: When using this utility model, the fabric is placed on the slitting device, and a laser cutter is used to cut the fabric at a designated position. Then, the position of the forward-moving plate 443 can be adjusted by the second forward-pushing cylinder 441 of the slitting frame, and the connecting rod 442 ensures that the forward-moving plate 443 moves along a straight path. When the opening pressure frame 448 moves to the position of the fabric opening, the second forward-pushing cylinder 441 stops operating. At this time, the second downward-pushing cylinder 447 can push the opening pressure frame 448 downward, thereby causing the top plate 31 of the opening pressure frame 448 to drive the pressure plates 35 of the two pressure plate devices towards... The downward movement presses down the fabric to be opened, causing it to open along the opening. After changing the fabric specifications on the bag opening machine, the distance between the two pressing devices needs to be adjusted. At this time, the sliding plate 33 of one of the pressing devices can be manually moved laterally along the crossbar 34, causing the sliding plate 33 of the pressing device to move the pressing plate 35 along the crossbar 34. This increases or decreases the distance between the pressing plates 35 of the two pressing devices. After adjusting to a suitable width, it can be used without disassembling the entire dividing frame for adjustment, making it simpler and more convenient to adjust the pocket fit width of the dividing frame.
