Description

Technical Field

[0001] This utility model belongs to the field of bag opening machine technology, and specifically relates to an inner pressure frame module of a bag opening machine. Background Technology

[0002] In the bag opening process of clothing and bags, the positioning plate is the basic component for positioning and pressing the fabric. Multiple positioning plates are often combined with a drive mechanism to complete the initial fixing of fabrics of different specifications, providing support for subsequent bag opening folding, sewing and other processes.

[0003] In actual processing scenarios, some positioning plates adopt an integral structure design, and the adjustment of multiple positioning plates is mostly concentrated in a single dimension. When faced with fabrics of uneven thickness, the integral positioning plate is difficult to adapt to the local thickness differences of the fabric. Moreover, the single-dimensional adjustment method is also difficult to cover the positioning requirements of different sized pockets in the length and width directions at the same time. This will cause the fabric to have insufficient local pressing and fluctuations in positional accuracy during processing, which will affect the consistency of the quality of the bag opening processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an internal pressure frame module for a bag opening machine.

[0005] To achieve the above objectives, this utility model provides an inner pressure frame module for a bag opening machine, including a bag opening machine bracket. The upper end of the bag opening machine bracket is provided with an inner frame assembly for fabric positioning. The inner frame assembly includes a servo motor fixedly installed on one side of the bag opening machine bracket. A first pulley is fixedly installed on the output end of the servo motor. A second pulley is rotatably connected to the side of the bag opening machine bracket near the servo motor. The first pulley and the second pulley are jointly fitted with a synchronous belt. A first transmission frame and a second transmission frame are alternately fixedly installed on opposite sides of the synchronous belt. An assembly plate is fixedly connected to the lower end of both the first transmission frame and the second transmission frame.

[0006] In the above technical solution, a first guide rail is fixedly connected to one side of each assembly plate, and the first guide rail is slidably connected to the bag opening machine bracket. A second guide rail is fixedly connected to one side of each assembly plate, and a support arm is slidably connected to each of the second guide rails. A cylinder is fixedly installed on each assembly plate corresponding to the support arm, and the output end of the cylinder is fixedly connected to the support arm. A first grid-shaped steel plate is fixedly connected to the middle position of the support arm. A plurality of first material fixing plates are sandwiched between the first grid-shaped steel plate and the support arm. A plurality of second material fixing plates are fixedly installed on one side of the lower end of the support arm.

[0007] In the above technical solution, a bracket is fixedly connected to the side of the support arm near the first fence-shaped steel plate, and an extension frame is fixedly connected to the other side of the support arm near the first fence-shaped steel plate. The bag opening machine bracket is fixedly installed with a first base plate corresponding to the support arm. A third guide rail is fixedly installed on one side of the first base plate, and a second base plate is slidably connected to the third guide rail.

[0008] In the above technical solution, two second cylinders are fixedly connected to one side of the first substrate, and the output ends of the two second cylinders are fixedly connected to the second substrate. Two fourth guide rails are slidably connected to one side of the second substrate. A transmission frame is fixedly connected to one end of each of the two fourth guide rails that are far apart from each other. A transmission rod is fixedly connected to one side of each transmission frame, and the transmission rod cooperates with the bracket.

[0009] In the above technical solution, the lower end of the second substrate is provided with two sets of first base plates, one set of which is fixedly connected to the second substrate, and the upper end of each of the first base plates is fixedly installed with a second fence-shaped steel plate, and a third fixed plate is movably inserted between the second fence-shaped steel plate and the first base plate.

[0010] In the above technical solution, a guide block is further provided on one side of the first base plate of another group, and a fifth guide rail is fixedly connected to one side of each extension frame, and the fifth guide rail is slidably connected to the guide block.

[0011] In the above technical solution, the two ends of the second fence-shaped steel plate are recessed downwards, and the recesses naturally form protrusions. The upper end of the third material plate has two slots corresponding to the protrusions.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The inner pressure frame module of this bag opening machine uses multiple sets of fixed plates as core functional components. The first and second fixed plates are driven by motors to achieve telescopic adjustment. At the same time, the third fixed plate, which can be telescopically adjusted, is used to build a positioning system. The position of the fabric is constrained from both length and width directions. This not only meets the processing requirements of different sized pockets, but also ensures the positional accuracy of the fabric during the processing.

[0013] (2) The positioning plate of this module adopts a segmented structure design. At the same time, the grid-shaped steel plate above the positioning plate is also flexible. When facing fabrics with uneven thickness or different thicknesses, the segmented positioning plate can deform autonomously according to the local thickness of the fabric, ensuring that each piece of fabric can be fully pressed. This solves the problem of insufficient pressing caused by differences in fabric thickness, which not only improves the adaptability of fabric positioning, but also ensures the quality stability of pocket processing, and is suitable for various fabric opening processing scenarios.

[0016] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-10The inner pressure frame module of the bag opening machine shown includes a bag opening machine bracket 1. The upper end of the bag opening machine bracket 1 is provided with an inner frame assembly for fabric positioning. The inner frame assembly includes a servo motor 2 fixedly installed on one side of the bag opening machine bracket 1. A first pulley 3 is fixedly installed at the output end of the servo motor 2. A second pulley 4 is rotatably connected to the side of the bag opening machine bracket 1 near the servo motor 2. The first pulley 3 and the second pulley 4 are together fitted with a synchronous belt 5. A first transmission frame 6 and a second transmission frame 7 are fixedly installed on opposite sides of the synchronous belt 5. An assembly plate 8 is fixedly connected to the lower end of both the first transmission frame 6 and the second transmission frame 7. One side of the assembly plate 8 is fixedly connected to a first guide rail 9, which is slidably connected to the bag opening machine bracket 1. One side of the assembly plate 8 is fixedly connected to a second guide rail 10, and a support arm 11 is slidably connected to each second guide rail 10. A cylinder 12 is fixedly installed on the assembly plate 8 corresponding to the support arm 11, and the output end of the cylinder 12 is fixedly connected to the support arm 11. A first grid-shaped steel plate 13 is fixedly connected at the middle position of the support arm 11. Several first fixed material plates 14 are sandwiched between the first grid-shaped steel plate 13 and the support arm 11. Several second fixed material plates 15 are fixedly installed on one side of the lower end of the support arm 11. A bracket 16 is fixedly connected on the side of the support arm 11 near the first grid-shaped steel plate 13. An extension frame 17 is fixedly connected on the other side of the support arm 11 near the first grid-shaped steel plate 13. A first base plate 18 is fixedly installed on the bag opening machine bracket 1 corresponding to the support arm 11. A third guide rail 19 is fixedly installed on one side of the first base plate 18, and a second base plate 20 is slidably connected to the third guide rail 19. Two second cylinders 21 are fixedly connected to one side of the first substrate 18. The output ends of the two second cylinders 21 are fixedly connected to the second substrate 20. Two fourth guide rails 22 are slidably connected to one side of the second substrate 20. A transmission frame 23 is fixedly connected to the ends of the two fourth guide rails 22 that are far apart from each other. A transmission rod 24 is fixedly connected to one side of each transmission frame 23. The transmission rod 24 cooperates with the bracket 16. Two sets of first base plates 25 are provided at the lower end of the second substrate 20. One set of first base plates 25 is fixedly connected to the second substrate 20. The upper end of the first base plate 25 is fixedly installed with a second fence-shaped steel plate 26. A third fixed plate 27 is movably inserted between the second fence-shaped steel plate 26 and the first base plate 25. A guide block 28 is provided on one side of another set of first base plates 25, and a fifth guide rail 29 is fixedly connected to one side of the extension frame 17. The fifth guide rail 29 is slidably connected to the guide block 28. The two ends of the second fence-shaped steel plate 26 are recessed downwards, and the recesses naturally form protrusions 30. The upper end of the third fixed plate 27 has two slots 31 corresponding to the protrusions 30.

[0018] Working principle: When servo motor 2 is started, its output drives the first pulley 3 to rotate. Since the first pulley 3 and the second pulley 4 are both fitted with a synchronous belt 5, the first pulley 3 drives the second pulley 4 to rotate synchronously through the meshing transmission of the synchronous belt 5. The first transmission frame 6 and the second transmission frame 7, which are fixed to opposite sides of the synchronous belt 5, move away from or closer to each other along the length of the bag-opening machine bracket 1 along the synchronous belt 5. The assembly plate 8, connected to the lower ends of the first transmission frame 6 and the second transmission frame 7, moves synchronously with them. The first guide rail 9 on one side of the assembly plate 8 slides along the bag-opening machine bracket 1, providing horizontal guidance for the assembly plate 8. During this process, the support arm 11 is connected to the assembly plate 8 via the second guide rail 10. The fifth guide rail 29 on one side of the extension frame 17 slides synchronously along the guide block 28, further constraining the movement trajectory of the support arm 11 until the assembly plate 8 drives the first elastic material fixing plate 14, the second elastic material fixing plate 15, the third elastic material fixing plate 27 and other material fixing components to move to a preset position that matches the size of the bag opening to be processed; wherein, the servo motor 2 is used as the power source, and the synchronous belt 5 ensures the synchronicity of the movement of the first transmission frame 6 and the second transmission frame 7, avoiding displacement deviation that leads to processing misalignment; the first guide rail 9 and the fifth guide rail 29 together play a guiding, constraining and bearing role, preventing the assembly plate 8 and the support arm 11 from shifting when they move, laying a precise positional foundation for subsequent processing.

[0019] In the initial state, the third elastic positioning plate 27 is in a retracted state. The protrusions 30 at both ends of the second fence-shaped steel plate 26 engage with one of the slots 31 on the upper end of the third elastic positioning plate 27, causing the third elastic positioning plate 27 to retract between the two sets of first base plates 25. At the same time, the bracket 16 of the support arm 11 near the first fence-shaped steel plate 13 is separated from the transmission rod 24. The piston rod of the second cylinder 21 remains retracted. The second base plate 20 is relatively fixed to the first base plate 18 through the third guide rail 19, and the fourth guide rail 22 is in the initial retracted position. The retraction and positioning of the third elastic positioning plate 27 is achieved by the engagement of the protrusions 30 and the slots 31, avoiding collision and interference between the support arm 11 and the third elastic positioning plate 27 when it moves. The first base plate 18 and the third guide rail 19 provide stable support for the second base plate 20, ensuring the accuracy of subsequent power transmission.

[0020] During positioning, the second cylinder 21 is activated, and the piston rod of the second cylinder 21 extends, pushing the second base plate 20 to move along the third guide rail 19 towards the support arm 11. The fourth guide rail 22 on one side of the second base plate 20 moves synchronously, driving the transmission frame 23 and transmission rod 24 at both ends to advance synchronously until the transmission rod 24 engages with the bracket 16 on the support arm 11. This facilitates the subsequent transmission of the support arm 11 to move the assembly plate 8 and the support arm 11 to the preset position. The extension frame 17 on the other side of the support arm 11 slides along the guide block 28 via the fifth guide rail 29 to ensure that the support arm 11 moves smoothly. As the support arm 11 moves, the second elastic positioning plate 15 at the lower end of the extension frame 17 moves closer to the fabric, and at the same time, the third elastic positioning plate 27 is pulled out, so that the third elastic positioning plate 27 slides along the gap between the first base plate 25 and the second fence-shaped steel plate 26 until the other slot 31 at the upper end of the third elastic positioning plate 27 engages with the protrusion 30 for a second time, realizing the extension and positioning of the third elastic positioning plate 27. The second cylinder 21 serves as the power source, and power is transmitted through the second base plate 20, the fourth guide rail 22, the transmission frame 23, and the transmission rod 24 to ensure that the support arm 11 and the third elastic material plate 27 move synchronously. The secondary engagement of the protrusion 30 and the slot 31 ensures the positional stability of the third elastic material plate 27 after it extends, providing precise edge support for the bag opening fold.

[0021] When the fabric is pressed, after the third elastic fixing plate 27 is positioned, the cylinder 12 is activated. The piston rod of the cylinder 12 extends, pushing the support arm 11 to move downward along the second guide rail 10. The first grid-shaped steel plate 13 in the middle of the support arm 11 follows synchronously, causing the first elastic fixing plate 14 between the first grid-shaped steel plate 13 and the support arm 11 to move downward. The second elastic fixing plate 15 at the lower end of the extension frame 17 and the extended third elastic fixing plate 27 move closer to the fabric synchronously until all three press against the upper surface of the fabric. During this process, the first elastic fixing plate 14, the second elastic fixing plate 15, and the third elastic fixing plate 27, as flexible components, conform to the fabric surface of different thicknesses through elastic deformation, avoiding indentations. The system uses cylinder 12 as a power source and transmits power through support arm 11 to achieve synchronous pressing of the fabric by three sets of elastic fixing plates. The first fence-shaped steel plate 13 and the second fence-shaped steel plate 26 provide limiting support for the first elastic fixing plate 14 and the third elastic fixing plate 27, respectively, to prevent the elastic fixing plates from shifting. The three sets of elastic fixing plates work together to ensure that the fabric does not shift or wrinkle during processing, providing a neat bag edge for subsequent sewing processes.

[0022] During the processing reset, after the processing of a single bag opening is completed, cylinder 12 is first activated. The piston rod of cylinder 12 retracts, pulling the support arm 11 upward along the second guide rail 10. The first elastic fixing plate 14, the second elastic fixing plate 15, and the third elastic fixing plate 27 simultaneously leave the fabric surface. Next, cylinder 21 is activated. The piston rod of cylinder 21 retracts, driving the second base plate 20 to move in the opposite direction along the third guide rail 19. The fourth guide rail 22, transmission frame 23, and transmission rod 24 are simultaneously reset. The transmission rod 24 separates from the bracket 16, and the support arm 11 returns to its initial horizontal position. The slot 31 and protrusion 30 of the third elastic fixing plate 27 return to their initial state. Finally, servo motor 2 is activated to rotate in the opposite direction. Servo motor 2 drives the first pulley 3 to rotate in the opposite direction. Through the synchronous belt 5 and the second pulley 4, the first transmission frame 6 and the second transmission frame 7 move closer to each other. The assembly plate 8 resets along the first guide rail 9, and all fixing components return to their initial positions, completing the entire processing cycle. Among them, the retraction of cylinder 12 enables the elastic material plate to detach from the fabric, the resetting of the second cylinder 21 enables the transmission mechanism to return to its initial state, and the reverse rotation of servo motor 2 enables the material fixing component to be horizontally reset, ensuring that the equipment can continuously perform bag opening processing and improve production efficiency.
