Description

Technical Field

[0001] The utility model belongs to the technical field of rapier looms, and particularly relates to a rapier loom edge finishing device. Background Art

[0002] Rapier looms are the most widely used shuttleless looms. In addition to the characteristics of high speed, high automation, and high efficiency of shuttleless looms, their positive weft insertion method has strong variety adaptability and can adapt to the weft insertion of various yarns. Moreover, rapier looms also have obvious advantages in multi-color weft weaving and can produce figured fabrics with up to 16 color wefts. With the replacement of shuttle looms by shuttleless looms, rapier looms will become the main production machines for woven fabrics.

[0003] After retrieval, Chinese Patent No. CN218989720U discloses a knitting garment edge finishing device, which includes an operating table. A support block is installed on the top of the operating table. Arc-shaped grooves are arranged at both ends of the support block along the width direction of the support block. A fixed roller is arranged above the arc-shaped grooves along the length direction of the arc-shaped grooves. Both ends of the fixed roller are connected with fixing plates through rotating bearings. The fixing plates are perpendicular to the operating table and are fixedly connected with the support block; A cylinder is coaxially arranged in each arc-shaped groove, and both ends of the cylinder are vertically installed on the fixing plate. When the utility model is used, the limiting plates at both ends of the cylinder move linearly under the action of a bidirectional lead screw to limit the knitted fabric passing under the fixed roller. With the tensioning effect of the fixed roller on the fabric, it is ensured that the fabric will not be distorted during the edge finishing process, improving the neatness and straightness of the circular cutting knife when finishing the edge of the fabric.

[0004] However, the above patent has the following problems:

[0005] Although the setting of the limiting plates limits the knitted fabric passing under the fixed roller and, combined with the tensioning effect of the fixed roller on the fabric, ensures that the fabric will not be distorted during the edge finishing process and improves the neatness and straightness of the circular cutting knife when finishing the edge of the fabric, the same principle applies to rapier looms. However, after the fabric is tensioned by the limiting plates, since the limiting plates are fixed in position, the edge finishing device cannot be adjusted in position, resulting in the inability of the rapier loom edge finishing device to perform edge finishing on different positions of the fabric during use. Therefore, different models need to be used to perform edge finishing on different positions of the fabric when the rapier loom edge finishing device is in use, thereby reducing the practicability of the rapier loom edge finishing device. Therefore, a rapier loom edge finishing device is proposed. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide an edge trimming device for a rapier loom, which solves the problem that the existing edge trimming device for a rapier loom cannot perform edge trimming on different positions of the fabric during use, so that different models need to be used for edge trimming of different positions of the fabric during use, thus reducing the practicability of the edge trimming device for a rapier loom.

[0007] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0008] The present utility model is an edge trimming device for a rapier loom, including a rapier loom main body. Both inner walls of the rapier loom main body are fixedly connected with mounting plates through bolts. One side of one of the mounting plates is fixedly connected with a driving motor. The output end of the driving motor is rotationally connected to the corresponding mounting plate. The output end of the driving motor penetrates through the corresponding mounting plate and is fixedly connected with a bidirectional threaded rod. Both ends of the bidirectional threaded rod are rotationally connected to the corresponding mounting plates. Both sides of the surface of the bidirectional threaded rod are threadedly connected with moving blocks. The lower surface of the moving block is fixedly connected with an electric push rod. The output end of the electric push rod is fixedly connected with a mounting box. One side of the mounting box is provided with a telescopic mechanism. A rotating rod is rotationally connected inside the mounting box. A cutting knife is fixedly connected to the surface of the rotating rod. A cutting motor for connecting with the rotating rod is fixedly connected to one side of the mounting box. Tensioning mechanisms are installed on both inner walls of the rapier loom main body.

[0009] Furthermore, both sides of the surfaces of the two moving blocks are jointly slidably inserted with stabilizing rods. Both ends of the two stabilizing rods are fixedly connected to the corresponding mounting plates. The stabilizing rods correspond to the bidirectional threaded rod.

[0010] Furthermore, the tensioning mechanism includes a fixing plate fixedly connected to the inner wall of the rapier loom main body. Sliding grooves are opened on both sides of the upper surface of the fixing plate. Two corresponding sliding blocks are slidably connected inside the two sliding grooves. The upper surfaces of the four sliding blocks are jointly fixedly connected with a mounting block.

[0011] Furthermore, the tensioning mechanism further includes a mounting groove opened on the upper surface of the mounting block. A tensioning plate is slidably connected inside the mounting groove. The tensioning plate corresponds to the cutting knife. The tensioning plate is slidably connected to the mounting block through the mounting groove.

[0012] Furthermore, a through groove is opened on one side of the mounting block. A rotating plate is rotationally connected inside the through groove through a rotating shaft. One side of the upper surface of the rotating plate is in contact with the lower surface of the tensioning plate. A return spring is fixedly connected to the other side of the upper surface of the rotating plate.

[0013] Furthermore, the reset spring is fixedly connected to the inner top wall of the through groove. The rotating plate is rotatably connected to the inside of the mounting block. A hollow tube is fixedly connected to the surface of the rotating plate, and a connecting rod is slidably inserted into the inside of the hollow tube.

[0014] Furthermore, the telescopic mechanism includes two corresponding main rods. One of the main rods is fixedly connected to the mounting box, and the other main rod is slidably connected to the surface of the mounting plate. One of the main rods is fixedly connected to the connecting rod. A secondary rod is slidably connected to the opposite sides of the two main rods. An activity groove corresponding to the other main rod is formed on the surface of the mounting plate.

[0015] The utility model has the following beneficial effects:

[0016] Through the settings of structures such as the mounting plate, bidirectional threaded rod, moving block, mounting box, cutting knife, and tensioning mechanism, when the rapier loom main body processes the yarn, the driving motor can be started as needed, so that the bidirectional threaded rod drives the two moving plates to adjust relatively, thereby making the electric push rod and the cutting knife move to the required positions. When the rapier loom main body trims the edge of the fabric, the trimming position can be adjusted according to the demand, improving the practicability of the rapier loom edge trimming device. Then, the electric push rod is started, so that the mounting box moves downward, thereby making the cutting knife move synchronously. At the same time, when the mounting box moves downward, it drives the telescopic mechanism to move synchronously, making the connecting rod push the rotating plate to rotate, so that the rotating plate drives the tensioning plate to move upward, thereby making the tensioning plate drive the produced fabric to move synchronously, so that the fabric is tensioned. Then, through the mutual cooperation of the cutting knife and the cutting motor, the edge trimming of the fabric is carried out, solving the problem that the existing rapier loom edge trimming device cannot perform edge trimming at different positions of the fabric during use, so that different models need to be used for edge trimming at different positions of the fabric when the rapier loom edge trimming device is in use, thereby reducing the practicability of the rapier loom edge trimming device.

[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

The output end of the driving motor 3 is rotationally connected to the corresponding mounting plate 2. The output end of the driving motor 3 penetrates through the corresponding mounting plate 2 and is fixedly connected with a bidirectional threaded rod 4. Both ends of the bidirectional threaded rod 4 are rotationally connected to the corresponding mounting plates 2. Both sides of the surface of the bidirectional threaded rod 4 are threadedly connected with moving blocks 5. Both sides of the surfaces of the two moving blocks 5 are commonly slidably inserted with a stabilizing rod 11. Both ends of the two stabilizing rods 11 are fixedly connected to the corresponding mounting plates 2. The stabilizing rod 11 corresponds to the bidirectional threaded rod 4. The lower surface of the moving block 5 is fixedly connected with an electric push rod 6. The output end of the electric push rod 6 is fixedly connected with a mounting box 7. Start the driving motor 3 to drive the bidirectional threaded rod 4 to rotate through its output end, so that the two moving blocks 5 move relatively, driving the electric push rod 6 and the mounting box 7 to move synchronously, so that the cutting knife 9 moves to the required position. Tensioning mechanisms are installed on both inner walls of the rapier loom main body 1. The tensioning mechanism includes a fixing plate 12 fixedly connected to the inner wall of the rapier loom main body 1. Both sides of the upper surface of the fixing plate 12 are provided with sliding grooves 13. Two corresponding sliding blocks 14 are slidably connected inside the two sliding grooves 13;

[0029] The upper surfaces of the four sliding blocks 14 are commonly fixedly connected with a mounting block 15. The tensioning mechanism further includes a mounting groove 16 opened on the upper surface of the mounting block 15. A tensioning plate 17 is slidably connected inside the mounting groove 16. When the mounting box 7 moves, synchronously make one of the main rods 23 move along with it, so that the main rod 23 drives the connecting rod 22 to move synchronously, thereby making the connecting rod 22 push the hollow tube 21 to move, so that the rotating plate 19 pushes the mounting block 15 to slide on the fixing plate 12, so that the tensioning plate 17 is continuously perpendicular to the cutting knife 9. The tensioning plate 17 corresponds to the cutting knife 9. The tensioning plate 17 is slidably connected to the mounting block 15 through the mounting groove 16. A through groove 18 is opened on one side of the mounting block 15. A rotating plate 19 is rotationally connected inside the through groove 18 through a rotating shaft. The rotating plate 19 is rotationally connected inside the mounting block 15. The surface of the rotating plate 19 is fixedly connected with a hollow tube 21.

One of the main rods 23 is fixedly connected to the mounting box 7;

[0030] Another main rod 23 is slidably connected to the surface of the mounting plate 2. One of the main rods 23 is fixedly connected to the connecting rod 22. The electric push rod 6 is started, causing the mounting box 7 to move downward, so that the mounting box 7 drives the cutting knife 9 and the rotating rod 8 to move synchronously. When the mounting box 7 moves downward, it synchronously drives the corresponding main rod 23 to move, causing the connecting rod 22 to move downward, causing the rotating plate 19 to rotate inside the through groove 18, and causing one side of the upper surface of the rotating plate 19 to push the tensioning plate 17 upward, causing the tensioning plate 17 to move relative to the cutting knife 9, causing the fabric to fit against the cutting knife 9, and at the same time causing the tensioning plate 17 to tension the fabric. A secondary rod 24 is slidably connected to the opposite sides of the two main rods 23. An activity groove corresponding to the other main rod 23 is provided on the surface of the mounting plate 2. A rotating rod 8 is rotatably connected inside the mounting box 7. A cutting motor 10 for connecting to the rotating rod 8 is fixedly connected to one side of the mounting box 7. A cutting knife 9 is fixedly connected to the surface of the rotating rod 8. The cutting motor 10 is started, and its output end drives the rotating rod 8 to rotate, so that the cutting knife 9 rotates synchronously to perform a cutting process on the fitted fabric, thereby performing an edge trimming process on the fabric produced by the rapier loom main body 1.

[0031] Specifically, when this rapier loom edge trimming device is in use: after the rapier loom main body 1 processes the yarn into fabric, according to the edge trimming requirements, the drive motor 3 is started, and its output end drives the bidirectional threaded rod 4 to rotate, so that the two moving blocks 5 move relative to each other, driving the electric push rod 6 and the mounting box 7 to move synchronously, causing the cutting knife 9 to move to the required position. When the mounting box 7 moves, it synchronously causes one of the main rods 23 to move along, causing the main rod 23 to drive the connecting rod 22 to move synchronously, so that the connecting rod 22 pushes the hollow tube 21 to move, causing the rotating plate 19 to push the mounting block 15 to slide on the fixed plate 12, so that the tensioning plate 17 remains perpendicular to the cutting knife 9. Then the electric push rod 6 is started, causing the mounting box 7 to move downward, so that the mounting box 7 drives the cutting knife 9 and the rotating rod 8 to move synchronously. When the mounting box 7 moves downward, it synchronously drives the corresponding main rod 23 to move, causing the connecting rod 22 to move downward, causing the rotating plate 19 to rotate inside the through groove 18, and causing one side of the upper surface of the rotating plate 19 to push the tensioning plate 17 upward, causing the tensioning plate 17 to move relative to the cutting knife 9, causing the fabric to fit against the cutting knife 9, and at the same time causing the tensioning plate 17 to tension the fabric. Then the cutting motor 10 is started, and its output end drives the rotating rod 8 to rotate, so that the cutting knife 9 rotates synchronously to perform a cutting process on the fitted fabric, thereby performing an edge trimming process on the fabric produced by the rapier loom main body 1.
