Description

Technical Field

[0001] This utility model relates to the field of curtain fabric processing technology, specifically to a curtain fabric edge cutting mechanism. Background Technology

[0002] Curtain fabric is a decorative material used to make curtains. It is usually made of a variety of materials, such as pure cotton, linen, polyester, and silk. It is sewn together through design and is often used in home decoration. It has functions such as blocking light, heat insulation, and light regulation. Different fabrics and designs can meet diverse needs.

[0003] Patent No. 201821610153.8 discloses a curtain processing and cutting device. The device uses a pressing block set at the top corner of the worktable to facilitate the lifting and pressing of the curtain fabric by the lifting column, which facilitates the efficient and accurate cutting of the curtain fabric by the cutting knife, avoids cutting errors caused by wrinkles, has a simple structure, and the lifting column adopts the principle of hydraulic device, which can lift and lower quickly and is easy to use.

[0004] However, existing curtain processing and cutting devices use a cutting blade to process the curtain fabric. However, the position of the cutting blade is fixed. When cutting the edges of the curtain fabric, the operator needs to manually adjust the position of the cutting blade, which is cumbersome and affects the processing efficiency of the curtain fabric. Therefore, a curtain fabric cutting mechanism is designed. Utility Model Content

[0005] In view of the problems in the background art, the present invention provides a curtain fabric cutting edge mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is a curtain fabric trimming mechanism, including a base frame. A fixed frame is bolted to the outside of the base frame. A drive plate A and a drive plate B are slidably connected to the inside of the fixed frame, with drive plate A located above drive plate B. A drive assembly for moving drive plate A and drive plate B is provided inside the fixed frame. A connecting frame is welded to the outside of drive plate A. Cutting blades A and B for trimming curtain fabric are slidably connected to the bottom of the connecting frame. An adjustment assembly for moving cutting blades A and B is provided inside the connecting frame. A bracket is welded to the end of drive plate A away from the connecting frame, and a pressure roller is rotatably connected to the inside of the bracket. A fixed plate for supporting the curtain fabric is screwed to one side of drive plate B.

[0007] By adopting the above technical solution, when the curtain fabric is to be edge-trimmed, the drive assembly inside the fixed frame drives drive plate A and drive plate B to move longitudinally towards each other. Then drive plate A drives the connecting frame to move, drive plate B drives the fixed plate to move, and then the fixed plate supports the curtain fabric. The cutter A and cutter B at the bottom of the connecting frame trim the curtain fabric, thereby improving the processing efficiency of the curtain fabric.

[0008] Specifically, a conveyor roller for feeding the curtain fabric is rotatably connected to one side of the base frame, and a motor A is bolted to one side of the base frame. The power output end of the motor A is keyed to a take-up roller for winding the curtain fabric.

[0009] By adopting the above technical solution, when the curtain fabric needs to be rolled up, the motor A outside the base frame converts the received electrical energy into mechanical energy, and the motor A drives the winding roller to rotate, thereby facilitating the winding up of the curtain fabric.

[0010] Specifically, the adjustment assembly includes a motor C, a bidirectional threaded rod, a threaded sleeve A, and a threaded sleeve B. The motor C, which provides power, is externally bolted to the connecting frame, and a bidirectional threaded rod is keyed to one side of the motor C. The bidirectional threaded rod is externally threaded to the threaded sleeve A and the threaded sleeve B. A cutter A is fixed to the bottom of the threaded sleeve A with a screw, and a cutter B is fixed to the bottom of the threaded sleeve B with a screw.

[0011] By adopting the above technical solution, when the positions of cutter A and cutter B need to be adjusted, the motor C outside the connecting frame converts the received electrical energy into mechanical energy. The motor C drives the bidirectional threaded rod to rotate. Subsequently, the threaded sleeves A and B outside the bidirectional threaded rod are limited by the external symmetrical structure, so that the threaded sleeves A and B move laterally in opposite directions or towards each other through the positive and negative threads opened on the surface of the bidirectional threaded rod. Then, the threaded sleeve A drives the cutter A to move, and the threaded sleeve B drives the cutter B to move, thereby facilitating the adjustment of the positions of cutter A and cutter B.

[0012] Specifically, the drive assembly includes a motor B, a bidirectional lead screw, a lead sleeve A, and a lead sleeve B. The motor B, which provides power, is bolted to the top of the inside of the fixing frame, and the power output end of the motor B is keyed to the bidirectional lead screw.

[0013] By adopting the above technical solution, when the bidirectional lead screw needs to be rotated, the motor in the fixed frame converts the received electrical energy into mechanical energy, thereby driving the bidirectional lead screw to rotate.

[0014] Specifically, the bidirectional lead screw is externally threaded with sleeve A and sleeve B. Sleeve A is welded to the outside of drive plate A, and sleeve B is welded to the outside of drive plate B.

[0015] By adopting the above technical solution, when the bidirectional lead screw rotates, the threaded sleeves A and B on the outside of the bidirectional lead screw are both limited by the external structure, so that the positive and negative threads opened on the surface of the bidirectional lead screw of the threaded sleeves A and B can move laterally towards each other or in opposite directions, thereby facilitating the adjustment of the position of the drive plate A and the drive plate B.

[0016] The beneficial effects of this utility model are:

[0017] (1) The curtain fabric trimming mechanism of this utility model, when the cutter A and cutter B trim the curtain fabric, the motor C outside the connecting frame converts the received electrical energy into mechanical energy. The motor C drives the bidirectional threaded rod to rotate. Then, the threaded sleeves A and B outside the bidirectional threaded rod are limited by the external symmetrical structure, so that the threaded sleeves A and B move laterally in opposite directions or towards each other through the positive and negative threads opened on the surface of the bidirectional threaded rod. Then, the threaded sleeve A drives the cutter A to move, and the threaded sleeve B drives the cutter B to move, so that the positions of the cutter A and cutter B can be adjusted, thereby facilitating the adjustment of the trimming position of the curtain fabric and improving the processing efficiency of the curtain fabric.

[0018] (2) The curtain fabric cutting mechanism of this utility model, when the drive plate A drives the connecting frame to move, the drive plate A drives the bracket on one side to move, so that the pressure roller in the bracket contacts the curtain fabric on the conveying roller, thereby facilitating the compression of the conveying and avoiding wrinkles in the curtain fabric.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To improve the processing efficiency of curtain fabric, as one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the curtain fabric trimming mechanism of this utility model includes a base frame 7. A fixing frame 1 is bolted to the outside of the base frame 7. A drive plate A2 and a drive plate B16 are slidably connected to the inside of the fixing frame 1, with the drive plate A2 located above the drive plate B16. A drive assembly 12 is provided inside the fixing frame 1 to drive the drive plate A2 and the drive plate B16 to move. A connecting frame 10 is welded to the outside of the drive plate A2. A cutter A11 and a cutter B19 for trimming the curtain fabric are slidably connected to the bottom of the connecting frame 10. An adjustment assembly 18 is provided inside the connecting frame 10 to drive the cutter A11 and the cutter B19 to move. A bracket 3 is welded to the end of the drive plate A2 away from the connecting frame 10, and a pressure roller 4 is rotatably connected to the inside of the bracket 3. A fixing plate 6 for supporting the curtain fabric is screwed to one side of the drive plate B16.

[0026] When the curtain fabric is to be trimmed, the drive assembly 12 inside the fixed frame 1 drives the drive plate A2 and drive plate B16 to move longitudinally towards each other. Then, the drive plate A2 drives the connecting frame 10 to move, and the drive plate B16 drives the fixed plate 6 to move. Then, the fixed plate 6 supports the curtain fabric, and the cutter A11 and cutter B19 at the bottom of the connecting frame 10 trim the curtain fabric, improving the processing efficiency of the curtain fabric.

[0027] For example, when retracting curtain fabric, such as... Figure 1 As shown, the present invention also includes a conveying roller 5 for conveying the curtain fabric rotatably connected to one side of the base frame 7, a motor A9 bolted to one side of the base frame 7, and a winding roller 8 for winding the curtain fabric keyed to the power output end of the motor A9.

[0028] When in use, when the curtain fabric needs to be rolled up, the motor A9 outside the base frame 7 converts the received electrical energy into mechanical energy, and the motor A9 drives the winding roller 8 to rotate, thus facilitating the winding up of the curtain fabric.

[0029] To adjust the positions of cutter A11 and cutter B19, for example, as follows: Figure 3 As shown, this utility model also includes the adjustment assembly 18, which includes a motor C20, a bidirectional threaded rod 21, a threaded sleeve A22, and a threaded sleeve B23. The connecting frame 10 is externally bolted to the motor C20, which provides power. The motor C20 is keyed to one side of the motor C20. The bidirectional threaded rod 21 is externally threaded to the threaded sleeve A22 and the threaded sleeve B23. The bottom screw of the threaded sleeve A22 is fixed with a cutter A11, and the bottom screw of the threaded sleeve B23 is fixed with a cutter B19.

[0030] In use, when the positions of cutter A11 and cutter B19 need to be adjusted, the motor C20 outside the connecting frame 10 converts the received electrical energy into mechanical energy. The motor C20 drives the bidirectional threaded rod 21 to rotate. Subsequently, the threaded sleeves A22 and B23 outside the bidirectional threaded rod 21 are limited by the external symmetrical structure, so that the threaded sleeves A22 and B23 move laterally in opposite directions or towards each other through the positive and negative threads opened on the surface of the bidirectional threaded rod 21. Then, the threaded sleeve A22 drives the cutter A11 to move, and the threaded sleeve B23 drives the cutter B19 to move, thereby facilitating the adjustment of the positions of cutter A11 and cutter B19.

[0031] To drive the bidirectional lead screw 14 to rotate, for example, as follows: Figure 2 As shown, the present invention also includes the following: the drive assembly 12 includes a motor B13, a bidirectional lead screw 14, a lead sleeve A15 and a lead sleeve B17; the motor B13, which provides power, is bolted to the top of the inside of the fixing frame 1; and the bidirectional lead screw 14 is keyed to the power output end of the motor B13.

[0032] When in use, when the bidirectional lead screw 14 needs to be rotated, the motor B13 in the fixed frame 1 converts the received electrical energy into mechanical energy, thereby driving the bidirectional lead screw 14 to rotate.

[0033] To adjust the positions of driver board A2 and driver board B16, for example, as follows: Figure 2 As shown, the present invention also includes a threaded sleeve A15 and a threaded sleeve B17 externally connected to the bidirectional lead screw 14. The threaded sleeve A15 is welded to the outside of the drive plate A2, and the threaded sleeve B17 is welded to the outside of the drive plate B16.

[0034] When the bidirectional lead screw 14 rotates, the threaded sleeves A15 and B17 on the outside of the bidirectional lead screw 14 are limited by the external structure, so that the positive and negative threads on the surface of the bidirectional lead screw 14 of the threaded sleeves A15 and B17 can move laterally towards each other or in opposite directions, thereby facilitating the adjustment of the position of the drive plate A2 and the drive plate B16.

[0035] In use, the curtain fabric is first fixed to the outside of the take-up roller 8 via the conveyor roller 5. The conveyor roller 5 is installed in the bearing seat of the base frame 7 via a deep groove ball bearing, and the bearing seat is welded to the inner wall of the base frame 7. Then, the motor C20 outside the connecting frame 10 is driven by the PLC controller to rotate the bidirectional threaded rod 21. The bidirectional threaded rod 21 is installed in the bearing seat of the connecting frame 10 via a deep groove ball bearing, and the bearing seat is welded to the inner wall of the connecting frame 10. Limiting sliders are symmetrically welded to the outside of the threaded sleeves A22 and B23 outside the bidirectional threaded rod 21, and the corresponding positions of the limiting sliders on the inner side of the connecting frame 10 are as follows. A limit slide bar is provided, and the limit slider slides in cooperation with the limit slide bar to restrict the running direction of threaded sleeves A22 and B23. This allows threaded sleeves A22 and B23 to move laterally in opposite directions or towards each other through the positive and negative threads on the surface of the bidirectional threaded rod 21. Then, threaded sleeve A22 drives cutter A11 to move, and threaded sleeve B23 drives cutter B19 to move, thereby adjusting the positions of cutters A11 and B19. Subsequently, motor C20 in the fixed frame 1, driven by the PLC controller, drives bidirectional lead screw 14 to rotate. Bidirectional lead screw 14 is mounted on the fixed frame 1 through a deep groove ball bearing. Inside the bearing housing, the bearing housing is welded to the inner wall of the fixed frame 1. The threaded sleeves A15 and B17 on the outside of the bidirectional lead screw 14 are both limited by the external structure. Limiting blocks are symmetrically arranged on the outside of threaded sleeves A15 and B17, and limiting grooves are provided on the inner side of the fixed frame 1 at the corresponding positions of the limiting blocks. The limiting blocks and limiting grooves slide in a sliding fit, restricting the running direction of threaded sleeves A15 and B17, so that threaded sleeves A15 and B17 move laterally towards each other on the positive and negative threads opened on the surface of the bidirectional lead screw 14. Then, threaded sleeve A15 drives the connecting frame 10 on the drive plate A2 to move, and threaded sleeve B17 moves... The fixed plate 6 on the drive plate B16 is moved, and the fixed plate 6 supports the curtain fabric. The cutter A11 and cutter B19 at the bottom of the connecting frame 10 trim the edges of the curtain fabric, improving the processing efficiency of the curtain fabric. At the same time, the bracket 3 on the drive plate A2 drives the pressure roller 4 to contact the curtain fabric on the conveying roller 5, so that the curtain fabric is squeezed to prevent the curtain fabric from shifting. Then, the motor A9 outside the base frame 7 is driven by the PLC controller to rotate the winding roller 8. The winding roller 8 is installed in the bearing seat of the base frame 7 through a deep groove ball bearing. The bearing seat is welded to the inner wall of the base frame 7, which facilitates the winding of the trimmed curtain fabric.
