Description

Technical Field

[0001] This utility model relates to the field of loom technology, and in particular to a double-cylinder clamping transmission device. Background Technology

[0002] During the operation of a rapier, the clamping and transmission of materials such as yarn and fabric require positional adjustments to coordinate with different weaving processes. The double-cylinder clamping transmission device, as a core component, directly impacts the production efficiency and operational flexibility of the rapier due to the ease of its positional adjustment. This device clamps materials via cylinder drive and simultaneously relies on a transmission mechanism to achieve positional changes in forward / backward and up / down directions. This adapts to the material transfer and positioning during the rapier process and the weaving requirements of fabrics of different specifications, making it a crucial foundation for ensuring the continuous and stable operation of the rapier.

[0003] However, existing double-cylinder clamping transmission devices for rapiers suffer from inconvenient position adjustment. The adjustment mechanisms for forward / backward movement and up / down pulling in some devices are scattered and lack a coordinated linkage mechanism. Multiple drive components must be operated step-by-step during adjustment, and the adjustment accuracy is difficult to control, easily leading to positional deviations. Furthermore, the position adjustments of the clamping mechanism and the transmission mechanism interfere with each other, requiring repeated calibration of transmission parameters when adjusting the clamping position. This cumbersome operation not only increases the intensity of manual labor but also prolongs process changeover time, making it difficult to meet the high-efficiency and flexible production requirements of rapiers. Therefore, a double-cylinder clamping transmission device is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dual-cylinder clamping transmission device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-cylinder clamping transmission device includes a main body, a vertical moving mechanism at the bottom of the main body, a plate at one end of the main body, a threaded screw on the outer wall of the main body, a forward and backward moving mechanism between the plate and the threaded screw, a first slider and a second slider on both sides of the outer wall at one end of the plate, and a clamping mechanism on the outer walls of the first and second sliders.

[0007] Preferably, the up-and-down moving mechanism includes a first cylinder and a connecting piece. A bracket is provided at the bottom of the main body of the equipment. The first cylinder and the bracket are fixedly connected. The connecting piece is rotatably connected to the top of the first cylinder. The connecting piece and the transmission threaded screw are rotatably connected.

[0008] Preferably, the forward and backward moving mechanism includes a tripod and a moving block. One side of the tripod is fixedly connected to the equipment plate. The tripod has the ability to rotate in opposite directions. The moving block is fixedly connected to one end of the tripod. The moving block is threadedly connected to a transmission threaded screw.

[0009] Preferably, the main body of the device is fixedly connected to a mounting plate, a servo motor is fixedly connected to the outer wall of the mounting plate, a drive wheel is fixedly connected to the servo motor, a driven wheel is fixedly connected to the transmission threaded screw, and a transmission belt is used to drive the drive wheel and the driven wheel.

[0010] Preferably, the clamping mechanism includes a second cylinder and a third cylinder. Fixed blocks are fixedly connected to both ends of the outer wall of one side of the equipment plate. The first slider and the second slider are located at both ends of the equipment plate, respectively. The two ends of the second cylinder are fixedly connected to the first slider and the fixed blocks, respectively. The fixed blocks and the second slider are connected and fixedly connected by two third cylinders, and the third cylinders are fixedly connected to each other. A spring is fixedly connected to the outer wall of the second slider. The second cylinder drives the first slider to move to the left, and the third cylinder drives the second slider to move to the right to achieve clamping.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. Multi-directional moving mechanism linkage improves operating efficiency. The first cylinder of the up and down moving mechanism drives the transmission threaded screw to rise and fall through the connecting part. The servo motor of the front and back moving mechanism drives the transmission threaded screw to rotate through the transmission belt, so that the moving block and the tripod push the equipment plate to move back and forth.

[0013] 2. Dual-cylinder coordinated clamping improves positioning accuracy. The second cylinder drives the first slider to move to the left, and the third cylinder drives the second slider to move to the right to form a symmetrical clamping force, ensuring that the material is in the middle position. The spring on the outer wall of the second slider can buffer the clamping impact, prevent the first slider from being displaced due to collision, reduce clamping deviation, and ensure the stability and consistency of material clamping on the loom.

The first cylinder 9 of the vertical moving mechanism drives the transmission threaded screw 3 to rise and fall through the connecting piece 10. The servo motor 8 of the front-back moving mechanism drives the transmission threaded screw 3 to rotate through the transmission belt 6, so that the moving block 11 cooperates with the tripod 12 to push the device plate 18 to move back and forth. The coordinated linkage of the various mechanisms reduces step-by-step operation, reduces manual intervention, and is suitable for the rapid conversion of multiple processes on a loom.

The connecting piece 10 and the transmission threaded screw 3 are rotatably connected. The first cylinder 9 of the up-and-down moving mechanism drives the transmission threaded screw 3 to rise and fall through the connecting piece 10.

[0024] The forward and backward moving mechanism includes a tripod 12 and a moving block 11. One side of the tripod 12 is fixedly connected to the equipment plate 18. The tripod 12 has the ability to rotate in opposite directions. The moving block 11 is fixedly connected to one end of the tripod 12. The moving block 11 is threadedly connected to the transmission threaded screw 3. The equipment body 1 is fixedly connected to a mounting plate 4. A servo motor 8 is fixedly connected to the outer wall of the mounting plate 4. A drive wheel 7 is fixedly connected to the servo motor 8. A driven wheel 5 is fixedly connected to the transmission threaded screw 3. A transmission belt 6 is connected between the drive wheel 7 and the driven wheel 5. The first cylinder 9 of the up and down moving mechanism drives the transmission threaded screw 3 to rise and fall through the connecting piece 10. The servo motor 8 of the forward and backward moving mechanism drives the transmission threaded screw 3 to rotate through the transmission belt 6, so that the moving block 11 cooperates with the tripod 12 to push the equipment plate 18 to move forward and backward.

[0025] The clamping mechanism includes a second cylinder 14 and a third cylinder 16. Fixed blocks 13 are fixedly connected to both ends of the outer wall of one side of the equipment plate 18. A first slider 15 and a second slider 17 are located at both ends of the equipment plate 18.

[0026] Working Principle: In the idle area of ​​this device, all the aforementioned components, specifically the structural parts, are connected. The specific connection methods should refer to the working principle described below, where the components are connected sequentially. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, without further explanation. When using this device, the up-and-down moving mechanism operates first. The first cylinder 9 on the support 2 extends and retracts, causing the connecting piece 10 to rotate, thereby driving the transmission threaded screw 3 to adjust its up-and-down position along the main body 1 of the equipment to adapt to the material clamping requirements of different heights. During forward and backward movement adjustment, the servo motor 8 on the mounting plate 4 starts, and its output drive wheel 7 drives the driven wheel 5 to rotate through the transmission belt 6, causing the transmission threaded screw 3 to rotate synchronously. The moving block 11, which is threadedly connected to the transmission threaded screw 3, moves along the screw axis. The moving block 11 drives the tripod 12 to unfold or retract, thereby pushing the equipment plate 18 to adjust its position in the forward and backward directions. When material needs to be clamped, the clamping mechanism starts working. The fixing blocks 13 at both ends of the equipment plate 18 serve as support points. The second cylinder 14 extends and pushes the first slider 15 to the left towards the center. At the same time, the two third cylinders 16 extend synchronously and drive the second slider 17 to the right towards the center. The two form opposing clamping forces to fix the material. The spring 19 on the outer wall of the second slider 17 undergoes elastic deformation when it contacts the first slider 15 during the clamping process, buffering the impact force at the moment of clamping and preventing the first slider 15 from being displaced due to hard collision. This ensures accurate clamping position. All mechanisms work together to complete the multi-directional position adjustment and stable clamping of the material.
