Description

Technical Field

[0001] This utility model relates to the technical field of garment processing machinery, and more specifically to a circulating plate moving and interchangeable device for a bag opening machine. Background Technology

[0002] Pocket opening machines are essential equipment in the garment manufacturing industry for producing pocket lips or zippered bags. The lower support plate, as a key component supporting the pocket lip or zipper, has a highly interchangeable movement mechanism that is crucial for achieving continuous production. As the garment manufacturing industry continues to demand higher production efficiency and automation, the interchangeable movement mechanism of the lower support plate in pocket opening machines is also constantly being improved and perfected.

[0003] Currently, most common bag-opening machine lower tray movement and interchangeability devices on the market mainly adopt a multi-axis drive structure. For example, CN214060880U discloses a circulating tray movement and interchangeability device for a bag-opening machine. This device includes a worktable and a clamping mechanism. The lower tray is moved and reset through an x-axis drive mechanism and a pair of y-axis drive mechanisms that can move synchronously. This structure makes the clamping mechanism more stable when completing x-axis and y-axis movements.

[0004] CN214060869U discloses a clamping mechanism for resetting the lower support plate of a bag opening machine. This mechanism includes a reset bracket and a clamping assembly mounted on the reset bracket. A lifting support plate brings the clamping assembly closer to the worktable of the bag opening machine, completing the clamping and releasing actions of the lower support plate. Regarding continuous production, CN112430916A discloses a continuous production garment bag opening machine. This machine utilizes an upper plate mechanism to position the lower support plate below the bag folding device and to support the bag lip or zipper. After the lower support plate moves with the material setting device and completes processing in the sewing device, the lower support plate reset device transfers it to below the bag folding device, achieving continuous processing.

[0005] CN214060872U discloses a lower tray reset device for a bag opening machine. This device uses an x-axis drive mechanism and a y-axis drive mechanism to move the clamping mechanism in the x and y directions on the worktable, retracting the lower tray in the sewing station and conveying it back to the bag folding station for release. CN223262403U discloses a tray circulation device for a bag opening machine. This device includes an x-axis guide rail assembly, a y-axis guide rail assembly, and a clamping assembly for gripping or releasing the tray. By simplifying the mechanical structure and configuration, the cost is reduced.

[0006] Existing pallet moving and interchangeable devices for bag-opening machines still suffer from the following technical problems: First, existing devices typically require independent lifting cylinders to achieve the pallet lifting function, resulting in structural redundancy and increased equipment costs and maintenance points; lifting and clamping actions need to be performed step by step, reducing processing efficiency; the integration of multiple drive components easily leads to patent infringement risks; excessive load can affect movement accuracy and product quality. These problems seriously restrict the further improvement of bag-opening machine production efficiency and the in-depth development of automation. Summary of the Invention

[0007] To address the technical problems of existing bag-opening machine lower pallet devices that require independent lifting cylinders, resulting in structural redundancy, increased equipment costs and maintenance points, separate lifting and clamping actions reducing processing efficiency, the risk of patent infringement due to the integration of multiple drive components, and the impact of excessive load on movement accuracy, this invention provides a bag-opening machine lower pallet device without independent lifting drive, achieving the technical effects of structural simplification, efficiency improvement, enhanced stability, and reduced patent infringement risk.

[0008] The technical solution adopted by the present invention to solve its technical problem is: to provide a circulating plate moving and interchangeable device for a bag opening machine, including a fixing member set on the bottom connecting plate; the fixing member is provided with a conical surface; a clamping cylinder fixed on the support frame; the clamping cylinder drives the clamping component to move toward the fixing member, and the fixing member moves along the axis of the fixing member under the action of the clamping component.

[0009] Preferably, the support frame moves on the X-axis and the Y-axis, and the support frame is equipped with a clamping cylinder; the clamping cylinder is equipped with a clamping component, the clamping component is equipped with a V-shaped groove, and the fixing component is located inside the V-shaped groove.

[0010] Furthermore, there are two clamping components, distributed on both sides of the clamping component, and the thickness of the clamping component is less than the height of the fixing component.

[0011] Furthermore, the thickness of the clamping component is less than the height of the protrusion of the fixing member on the bottom connecting plate.

[0012] Optionally, the clamping component contacts the tapered surface on the fixing member, and the clamping component does not extend beyond the tapered surface on the fixing member in the direction of the fixing member's axis.

[0013] Preferably, the V-grooves on the clamping components are of the same size and shape.

[0014] Furthermore, the number of the fixing components is at least one, and each fixing component is equipped with a clamping cylinder that functions accordingly.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Simplified structure: This invention eliminates the independent lifting cylinder. The clamping cylinder drives the clamping component to move towards the fixed part. The lifting function of the pallet is achieved by the cooperation of the conical surface and the V-shaped groove, which reduces the number of parts, lowers equipment cost and maintenance points.

[0017] 2. Improved efficiency: This invention achieves simultaneous "clamping + lifting". While the clamping cylinder clamps the conical fixing part, the fixing part automatically moves up along the axis due to the guiding effect of the conical surface, reducing unnecessary movements, shortening the time of a single action, and improving the efficiency of continuous processing.

[0018] 3. Enhanced stability: The present invention adopts a combination of conical fixing parts and V-shaped grooves to automatically center the pallet during the lifting process. Compared with the existing lifting cylinders, the positioning accuracy is higher, which improves the stability and accuracy of pallet positioning.

[0019] 4. Reduce patent coverage risk: Through innovative structural design, this invention avoids the patent coverage risk of multi-drive component integration in existing technologies, achieving the goals of cost reduction, efficiency improvement, and patent compliance.

[0026] A movable interchangeable device for the lower support plate 8 of a bag opening machine includes a fixing member 5 disposed on a bottom connecting plate 6 and a clamping cylinder 10 fixed on a support frame 1. The fixing member 5 is provided with a conical surface 51. The clamping cylinder 10 drives the clamping component 4 to move toward the fixing member 5, and the fixing member 5 moves along the axis of the fixing member 5 under the action of the clamping component 4.

[0027] The support frame 1 can move on the X-axis 2 and also on the Y-axis 3. The support frame 1 is equipped with a clamping cylinder 10, the clamping cylinder 10 is equipped with a clamping component 4, the clamping component 4 is equipped with a V-groove 41, and the fixing component 5 is located inside the V-groove 41.

[0028] There are two clamping components 4, distributed on both sides of the clamping component 4. The thickness of the clamping component 4 is less than the height of the fixing member 5, specifically, the thickness of the clamping component 4 is less than the height of the fixing member 5 protruding from the bottom connecting plate 6. This design ensures that the clamping component 4 can effectively contact the fixing member 5 without interfering with the movement of the bottom connecting plate 6.

[0029] The clamping component 4 contacts the tapered surface 51 on the fixing component 5, and the clamping component 4 does not extend beyond the tapered surface 51 on the fixing component 5 in the direction of the axis of the fixing component 5. This structural design ensures that the clamping component 4 can accurately act on the tapered surface 51 of the fixing component 5 during the clamping process, thereby achieving precise positioning and clamping of the fixing component 5.

[0030] In a preferred embodiment, the V-grooves 41 on the clamping member 4 are all the same size and shape. This design ensures that the clamping force of the clamping member 4 on the fixing member 5 is evenly distributed, avoiding the displacement of the fixing member 5 due to uneven clamping force.

[0031] The number of fixing parts 5 is at least one, and each fixing part 5 is equipped with a clamping cylinder 10 that functions accordingly. When multiple fixing parts 5 are used, the stability and reliability of the entire mobile interchangeable device can be improved.

[0032] In actual operation, when the lower support plate 8 needs to be moved and reset, the support frame 1 first moves to the predetermined position on the X-axis 2 and Y-axis 3, and then the clamping cylinder 10 drives the clamping component 4 to move towards the fixing component 5. Since the V-groove 41 on the clamping component 4 matches the conical surface 51 on the fixing component 5, when the clamping component 4 contacts the conical surface 51, a component force is generated along the axis of the fixing component 5, causing the fixing component 5 to move upward. This movement method ensures that the fixing component 5 can accurately return to the predetermined position, thereby achieving accurate reset of the lower support plate 8. The Y-axis power system 7 drives the support frame 1 to move along the Y-axis 3, the clamping cylinder 10 drives the clamping cylinder claw 9 to move, the clamping cylinder claw 9 drives the clamping component 4 to clamp the fixing component 5, and the conical surface 51 on the fixing component 5 drives the bottom connecting plate 6 to move along the axis of the fixing component 5 under the action of the clamping component 4, thereby realizing the movement of the lower support plate 8.

[0033] The design of this movable interchangeable device ensures that the lower support plate 8 of the bag opener remains stable during operation and can accurately return to its original position when needed, improving the working efficiency and product quality of the bag opener. Furthermore, due to the cylinder drive and conical surface 51 contact design, the device is easy to operate, has low maintenance costs, and a long service life.

[0034] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
