Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically to a rotary bag opening machine template moving device. 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 existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: After the existing bag opening machine cuts the fabric, it is necessary to remove the cutting template placed on the slitting device and put in the bag fabric and sewing template. At this time, a template moving device is required to grab and replace the template. The existing template moving device is driven by multiple servo motors and transmission components, and multiple slots need to be opened under the machine table. There are many parts, and maintenance and installation are very complicated. Moreover, when grabbing the template, it can only be grabbed and transported by moving horizontally and vertically, and the time spent on each template replacement is long. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a rotary bag opening machine template moving device that is simple in structure, easy to maintain, and fast in template replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary bag-opening machine template moving device, comprising a transverse slot integrally formed on the bag-opening machine worktable and a gripping device installed inside the bag-opening machine and extending out of the worktable at the top. The gripping device includes a bracket fixedly installed inside the bag-opening machine and a rotating motor installed on the end of the bracket. A screw with its end movably engaged with the inner wall of the bracket is connected to the rotating shaft of the rotating motor. A moving plate with its bottom engaged with the outer wall of the screw is also slidably provided on the bracket. A transverse extension block is provided on the upper surface of the moving plate. A rotating cylinder is movably engaged on the transverse extension block. A rotary gripping device is also fixedly installed on the moving plate.

[0006] A further improvement is that the top surface of the bracket is also provided with a guide rail plate whose top surface fits against the bottom surface of the movable plate and can slide against each other.

[0007] A further improvement is that the rotating gripping device includes a fixed frame whose bottom is fixedly connected to the top surface of the moving plate and a rotating column that penetrates and is movably engaged with the fixed frame. The bottom surface of the rotating column is provided with a connecting rod that is movably engaged with the end of the rotating cylinder. The top surface of the rotating column is provided with a placement tray, and a template fixing device is provided on one side edge of the placement tray.

[0008] A further improvement is that the top surface of the placement tray is also provided with a side-push cylinder, and the end of the side-push cylinder is fixedly connected to one side of the template fixing device.

[0009] A further improvement is made to the template fixing device, which includes a gripping tray and a hook integrally formed on one side edge of the gripping tray. The gripping tray is equipped with a gripping cylinder, and the end of the gripping cylinder is equipped with a movable locking block with a through groove. The gripping tray is equipped with a gripping hook in the middle section that is movably engaged with the gripping tray. One end of the gripping hook is slidably connected to the inner wall of the through groove of the movable locking block.

[0010] A further improvement is that a positioning stud is provided on the top edge of the gripping tray.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After opening the fabric and overlapping the bag fabric with the opened fabric, the template for placing the bag fabric can be taken out by the gripping device. During the gripping process, the moving plate is moved laterally on the support by rotating the motor and screw, and the rotating column is driven to rotate by rotating the cylinder and connecting rod, so that the placement tray loaded on the rotating column can rotate synchronously. With the help of the hook on the gripping device and the gripping hook that can be opened and closed by the gripping cylinder, the columnar protrusion on the template is gripped, and the template is quickly separated from the separating device by rotation. Compared with the traditional gripping device driven by the servo mechanism to move laterally, the separation speed is faster by separating the template by rotation, and there is no need to set up a complex servo transmission mechanism. The structure is simpler, the operation is easier, and the maintenance is more convenient. Attached Figure Description

Detailed Implementation

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] See Figure 1-5As shown, the technical solution adopted in this specific embodiment is: a rotary bag-opening machine template moving device, including a transverse sliding slot 22 integrally formed on the bag-opening machine worktable 2 and a gripping device 6 installed inside the bag-opening machine and extending out of the worktable 2 at the top. The gripping device 6 includes a bracket 61 fixedly installed inside the bag-opening machine and a rotary motor 66 installed on the end of the bracket 61. A screw 65 with its end movably engaged with the inner wall of the bracket 61 is connected to the rotating shaft of the rotary motor 66. A movable plate 64 with its bottom engaged with the outer wall of the screw 65 is also slidably provided on the bracket 61. A transverse extension block 68 is provided on the upper surface of the movable plate 64, and a rotary cylinder 69 is movably engaged on the transverse extension block 68. A rotating gripping device 67 is also fixedly installed on the movable plate 64. The rotating gripping device 67 includes a fixed frame 672 whose bottom is fixedly connected to the top surface of the movable plate 64, and a rotating column 678 that penetrates and is movably engaged with the fixed frame 672. The bottom surface of the rotating column 678 is provided with a connecting rod 671 that movably engages with the end of the rotating cylinder 69. The top surface of the rotating column 678 is provided with a placement tray 673. A template fixing device 676 is provided on one side edge of the placement tray 673. The template fixing device 676 includes a gripping tray 71 and a hook 711 integrally formed on one side edge of the gripping tray 71. A gripping cylinder 72 is provided on the gripping tray 71, and the end of the gripping cylinder 72 is provided with a penetrating... The slot's movable locking block 73 and the gripping tray 71 are equipped with a gripping hook 74 that engages with the gripping tray 71 in the middle. One end of the gripping hook 74 is slidably connected to the inner wall of the slot of the movable locking block 73. In use, after opening the fabric and overlapping the fabric with the opened bag, the template for placing the bag can be removed by the gripping device 6. During the gripping process, the moving plate 64 is moved laterally on the support 61 by rotating the motor 66 in conjunction with the screw 65, while the rotating cylinder 69 in conjunction with the connecting rod 671 drives the rotating column 678 to rotate, thereby causing the placement tray 673 loaded on the rotating column 678 to rotate synchronously, cooperating with the gripping... The hook 711 on device 6 and the gripping hook 74 which can be controlled to open and close by gripping cylinder 72 can cause the inner end of the gripping hook 74 to be pushed outward under the action of moving block 73 when gripping cylinder 72 extends, thereby causing its outer end to retract. At this time, it can work with hook 711 to grip the columnar protrusion on the template. The thrust generated by rotating cylinder 69 causes template fixing device 676 to rotate, thereby quickly rotating and separating the template from the splitting device 4. Compared with the traditional servo mechanism driven transverse movement device, separating the template by rotation makes the separation speed faster, and there is no need to set up a complex servo transmission mechanism. The structure is simpler, the operation is easier, and the maintenance is more convenient. The top surface of the support 61 is also provided with a guide rail plate 63 that is in contact with the bottom surface of the moving plate 64 and can slide against each other, which helps to make the moving trajectory of the moving plate 64 straighter and avoids it from tilting and affecting the gripping action of the gripping device 67. The top surface of the tray 673 is also provided with a side-push cylinder 674. The end of the side-push cylinder 674 is fixedly connected to one side of the template fixing device 676, which facilitates the template fixing device 676 to move laterally under the action of the side-push cylinder 674, thereby enabling the template fixing device 676 to obtain a larger lateral movement range and greater flexibility in use. The top edge of the gripping tray 71 is also provided with a positioning stud 75, which is convenient to turn the positioning stud 75 to move it up and down. By moving the lower end of the positioning stud 75 up and down, it can make the lower end abut against the template when the gripping tray 71 is moved to a suitable height during the gripping process. This means that when gripping the template, there is no need to wait for the gripping tray 71 to be fully lowered, and the gripping speed is faster.

[0016] The working principle of this utility model is as follows: When using this utility model, after making an opening in the fabric and overlapping the fabric bag with the opened fabric, the template for placing the bag fabric can be removed by the gripping device 6. During the gripping process, the moving plate 64 is moved laterally on the support 61 by rotating the motor 66 in conjunction with the screw 65. Meanwhile, the rotating cylinder 69, in conjunction with the connecting rod 671, drives the rotating column 678 to rotate, thereby causing the placement tray 673 loaded on the rotating column 678 to rotate synchronously. This is coordinated with the hook 711 on the gripping device 6 and the opening and closing controllable by the gripping cylinder 72. When the gripping cylinder 72 extends, the gripping hook 74, under the action of the moving block 73, pushes its inner end outward, causing its outer end to retract. At this time, it can work with the hook 711 to grip the columnar protrusion on the template. The thrust generated by the rotating cylinder 69 causes the template fixing device 676 to rotate, quickly separating the template from the separating device 4. Compared with the traditional servo mechanism driven transverse device, separating the template by rotation makes the separation speed faster, and there is no need to set up a complex servo transmission mechanism. The structure is simpler, the operation is easier, and the maintenance is more convenient.
