Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical technology and relates to a sewing equipment, particularly a quick-change mechanism for a circulating plate in a sewing equipment. Background Technology
[0002] Clothing pockets come in a wide variety of types, including single-lip pockets, double-lip pockets, slanted pockets, and zippered pockets. Fully automatic laser pocket opening machines, with their high-precision laser cutting and automated sewing technologies, are capable of efficiently processing various complex pocket shapes. This capability allows them to significantly reduce labor costs in the clothing pocket manufacturing industry.
[0003] The current bag opening machine processing technology involves first opening the bag opening on the fabric, and then sewing the pre-processed bag lip and bag lip zipper and other structures onto the bag opening in sequence, thus completing the overall processing of the bag.
[0004] To improve pocket processing efficiency, Chinese utility model patent CN217298233U discloses a mold tray alternating device, including a worktable, a bag opening structure disposed above the worktable, and an X-axis drive mechanism for driving the bag opening structure to move horizontally along the length direction of the worktable. It also includes: at least two trays disposed on the worktable; a tabletop drive mechanism for driving the trays to move along the width direction of the worktable at one end of the worktable; a Y-axis drive mechanism for driving the trays to move along the width direction of the worktable on the X-axis drive mechanism; a Y-axis gripping component for gripping and fixing the trays on the Y-axis drive mechanism; and a clamping component on the bag opening structure for picking up the trays and cooperating with the X-axis drive mechanism to complete the workstation transition.
[0005] The aforementioned replacement device can continuously and smoothly place the materials to be processed, enabling continuous processing and thus effectively improving processing efficiency. However, in order to stabilize the pallet, limit blocks and limit grooves need to be added to the pallet, and correspondingly, a holding structure needs to be added to the holding cylinder. This increases processing costs and debugging difficulty. Moreover, the stability and synchronization of ordinary cylinders are poor, and a clamping mechanism also needs to be set in front, making the overall structure more complex. Utility Model Content
[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a simple, quick-change mechanism for a circulating plate in sewing equipment.
[0007] The purpose of this utility model can be achieved through the following technical solution: a quick replacement mechanism for a circulating plate in sewing equipment, wherein one side of the circulating plate is a long strip-shaped plate base, and both ends of the plate base have connecting holes arranged along the thickness direction of the plate base. This replacement mechanism includes a base plate, a frame, a slide, and a horizontally arranged connecting plate. The frame is provided with a first driving mechanism for driving the slide to move left and right, and the slide is provided with a lifting component for driving the connecting plate to move up and down. The characteristic is that the base plate is provided with a second driving mechanism for driving the frame to move back and forth. Both ends of the connecting plate are vertically fixed with guide rods that match the connecting holes, and the lower ends of the two guide rods are respectively inserted into the two connecting holes to align the position of the circulating plate. A vacuum suction cup is vertically fixed in the middle of the connecting plate, and the bottom surface of the guide rod is lower than the vacuum suction cup.
[0008] This replacement mechanism is used in conjunction with the pocket processing equipment, and the specific operating process is as follows: There are two circulation plates, arranged side by side in the feeding area; the operator places the bag lip and zipper on the front circulation plate, the pocket processing equipment moves to the feeding area and pulls the front circulation plate into the processing area, with the processing area and feeding area arranged side by side; then the lifting component drives the connecting plate to move down, first inserting the lower ends of the two guide rods into the two connecting holes to align the position of the rear circulation plate, and as the connecting plate continues to move down, the vacuum suction cup will attract the rear circulation plate, and through the action of the second drive mechanism, the rear circulation plate will be moved forward, and then the connecting plate will be reset; when the processing step is completed, with the cooperation of the first drive mechanism, the second drive mechanism and the lifting component, the connecting plate is moved to the processing area and grabs the circulation plate at that position and resets it to the rear of the feeding area, thus completing the replacement of the circulation plates.
[0009] This application uses only the guide rod and the connecting hole set on the circulation plate to align the position of the circulation plate, and the circulation plate can be stably and accurately fixed on the connecting plate by vacuum suction cup adsorption. It has the advantages of simple structure, low cost and low debugging difficulty.
[0010] In the aforementioned quick-change mechanism for the circulating plate in sewing equipment, the lower end of the guide rod is a frustum with a diameter that gradually decreases from top to bottom, and the wall of the connecting hole has a conical surface for contacting and engaging with the frustum. This contact engagement between the frustum and the conical surface further enhances the positioning accuracy of the circulating plate, thereby improving the quality and precision of pocket processing.
[0011] In the aforementioned quick-change mechanism for the circulating plate of the sewing equipment, the connecting hole is through-hole to facilitate its processing.
[0012] In the aforementioned quick-change mechanism for the circulating plate of the sewing equipment, there are at least two vacuum suction cups distributed along the arrangement direction of the two guide rods to enhance the adsorption force on the circulating plate and ensure that the circulating plate is transported smoothly.
[0013] In the aforementioned quick-change mechanism for the circulating plate in sewing equipment, the connecting plate includes a long plate body and a connecting frame. The aforementioned lifting component acts on the upper end of the connecting frame, and the aforementioned vacuum suction cup and guide rod are both mounted on the long plate body. The long plate body is connected to the lower end of the connecting frame via a connecting structure, allowing the long plate body to slide up and down relative to the connecting frame and lock in the sliding position. The long plate body can slide up and down independently to adjust the positions of the vacuum suction cup and guide rod, facilitating subsequent adjustments.
[0014] In the aforementioned quick-change mechanism for the circulating plate in the sewing equipment, the long plate has an L-shaped cross-section, and the lower end of the connecting frame presses against the front side of the upper end of the long plate. The connecting structure includes a strip groove that runs through the connecting frame from front to back, and the strip groove is vertically arranged. The long plate has a corresponding threaded hole, and a screw is provided in the strip groove. The screw shank is screwed into the threaded hole, and the screw head is pressed against the connecting frame. In this way, rotating the screw can control the tightness of the long plate, which is convenient to use.
[0015] In the aforementioned quick-change mechanism for the circulating plate of the sewing equipment, the frame and the base plate are slidably connected to improve the smoothness of the frame's sliding.
[0016] In the aforementioned quick-change mechanism for the circulating plate of the sewing equipment, the second drive mechanism includes a second motor fixed on the base plate, which drives the frame to move through a screw and nut transmission structure.
[0017] Compared with existing technologies, the quick-change mechanism for the circulating plate in this sewing equipment has the following advantages:
[0018] 1. This application uses only the guide rod and the connecting hole set on the circulation plate to align the position of the circulation plate, and the circulation plate can be stably and accurately fixed on the connecting plate by vacuum suction cup adsorption. It has the advantages of simple structure, low cost and low debugging difficulty.
[0019] 2. The contact fit between the frustum and the conical surface can further enhance the positioning accuracy of the circulation plate, thereby improving the processing quality and precision of the pocket. Attached Figure Description

[0025] like Figure 1 As shown, one side of the circulation plate 1 is a long strip-shaped plate base 1a, and both ends of the plate base 1a have connecting holes 1b arranged along the thickness direction of the plate base 1a. Preferably, the connecting holes 1b are through-holes to facilitate processing.

[0027] This replacement mechanism is used in conjunction with the pocket processing equipment, and the specific usage process is as follows: There are two circulation plates 1, which are arranged side by side in the feeding area; the operator places the bag lip and zipper on the front circulation plate 1, the pocket processing equipment moves to the feeding area and drives the front circulation plate 1 into the processing area, and the processing area and the feeding area are arranged side by side; then the lifting component 6 drives the connecting plate 5 to move down, first inserting the lower ends of the two guide rods 7 into the two connecting holes 1b to align the position of the rear circulation plate 1, and as the connecting plate 5 continues to move down, the vacuum suction cup 8 will attract the rear circulation plate 1, and through the action of the second drive mechanism, the rear circulation plate 1 will be moved forward, and then the connecting plate 5 will be reset; when the processing process is completed, with the cooperation of the first drive mechanism, the second drive mechanism and the lifting component 6, the connecting plate 5 is moved to the processing area and grabs the circulation plate 1 at that position and resets it to the rear of the feeding area, so as to complete the alternation of the circulation plates 1.
[0028] This application uses only the guide rod 7 and the connecting hole 1b set on the circulation plate 1 to align the position of the circulation plate 1, and the circulation plate 1 can be stably and accurately fixed on the connecting plate 5 by the vacuum suction cup 8. It has the advantages of simple structure, low cost and low debugging difficulty.
