Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jacquard machines, in particular to an improved composite fabric jacquard machine. Background Technique
[0002] A jacquard machine is a textile tool that can weave fabrics with complex patterns, while ordinary looms can only weave plain fabrics. During the operation of the jacquard machine, the warp threads often break. If the break of the warp thread pair is not dealt with in time, it will cause defects on the produced fabric surface and affect the quality. For advanced electronic jacquard machines, when the warp thread breaks, the intelligent control system installed on it comprehensively analyzes the data of various sensors, including tension, position, speed, etc., and the information provided by image recognition technology, and then judges whether the warp thread breaks through algorithm analysis of these data. For most ordinary jacquard machines, they judge whether the warp thread breaks through the warp stop motion installed on the warp thread. When the warp thread breaks, the warp stop motion on the warp thread falls under its own gravity and touches the power equipment, so that the jacquard machine stops working.
[0003] Since most warp stop motions are installed on the warp thread by threading the warp thread through the slots of the warp stop motion, the movement of the warp thread during the operation of the jacquard machine will cause continuous friction between it and the warp stop motion. Therefore, although the warp stop motion can judge the break of the warp thread, its long-term friction with the warp thread will cause the slots at the friction part of the warp stop motion to be worn or the protective coating on the surface of the warp stop motion to be worn. This kind of wear not only affects the service life of the warp stop motion and requires regular replacement, but also when the wear is serious and the slots are worn unevenly, it will cause the warp thread to be subjected to uneven friction and tension, and it is easy to deviate, twist or break.
[0004] Therefore, an improved composite fabric jacquard machine is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide an improved composite fabric jacquard machine to solve the problem that since most warp stop motions are installed on the warp thread by threading the warp thread through the slots of the warp stop motion, the movement of the warp thread during the operation of the jacquard machine will cause continuous friction between it and the warp stop motion. Therefore, although the warp stop motion can judge the break of the warp thread, its long-term friction with the warp thread will cause the slots at the friction part of the warp stop motion to be worn or the protective coating on the surface of the warp stop motion to be worn. This kind of wear not only affects the service life of the warp stop motion and requires regular replacement, but also when the wear is serious and the slots are worn unevenly, it will cause the warp thread to be subjected to uneven friction and tension, and it is easy to deviate, twist or break, which is mentioned in the above background technique.
[0006] To achieve the above object, the present utility model provides the following technical solution: An improved composite fabric jacquard machine, comprising a jacquard machine body and warp threads provided in the jacquard machine body. A limit seat is fixedly installed on the jacquard machine body. A warp stop is provided in the limit seat. A rolling assembly for removing friction is provided between the warp stop and the warp threads. The rolling assembly includes balls provided in the warp stop. A connecting piece is fixedly connected to the bottom end of the warp stop. A roller is provided at the bottom end of the connecting piece. It further includes a top plate provided at the top end of the limit seat. A connecting assembly for quickly removing the top plate is provided between the top plate and the limit seat.
[0007] Preferably, a rotating shaft is fixedly connected in the warp stop, and the balls are rotatably connected to the rotating shaft. There are two balls, and the two balls are distributed in a staggered manner in the vertical position.
[0008] Preferably, a chute adapted to the balls is opened in the limit seat, and the balls are slidably connected in the chute.
[0009] Preferably, a connecting rod is fixedly connected to the bottom end of the connecting piece, and the connecting rod is rotatably connected to the roller. The warp thread is slidably connected to the roller.
[0010] Preferably, a long groove is opened in the connecting piece, and a lifting handle is fixedly connected to the top end of the warp stop.
[0011] Preferably, a bearing frame is fixedly connected to the bottom end of the limit seat. A pressure sensor is fixedly installed on the bearing frame. The top end of the pressure sensor is fixedly connected to a support plate. Path grooves for the connecting piece to move are opened on both the support plate and the bearing frame.
[0012] Preferably, the connecting assembly includes a pull rod slidably connected in the limit seat. A moving plate is fixedly connected to the pull rod. A spring is fixedly connected between the moving plate and the limit seat. A card slot is opened on the protruding panel of the top plate, and the pull rod is embedded in the card slot.
[0013] Preferably, an inclined surface is opened on the pull rod, and an inclined surface adapted to the inclined surface is provided at the bottom end of the protruding panel of the top plate.
[0014] The beneficial effects of the present utility model:
[0015] When the warp thread breaks in the present utility model, through the setting of the rolling assembly, components such as the warp stop and the roller move downward to the support plate under the action of gravity, so that the pressure sensor on the bearing frame senses the signal, and then sends a signal to make the external controller pause the jacquard machine body, avoiding the jacquard machine body continuing to work in the case of thread breakage and affecting the product quality.
[0016] The setting of the roller makes the warp thread no longer contact with the warp stop pin to generate friction, so that the warp stop pin is not affected by friction and surface wear occurs, making its service life longer, avoiding the influence on the warp thread caused by the surface wear of the warp stop pin, and the friction between the warp thread and the roller is rolling friction. Therefore, compared with the sliding friction between the warp thread and the warp stop pin in the traditional jacquard machine body, the friction force is greatly reduced, further enhancing the protection of the warp thread.

Detailed Description of the Embodiments
[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further elaborate on the present invention in combination with specific embodiments.

[0027] As Figures 1 to 6 shown, a specific embodiment of this utility model provides an improved composite fabric jacquard machine, which includes a jacquard machine body 1 and warp threads 2 arranged in the jacquard machine body 1. A limit seat 3 is fixedly installed on the jacquard machine body 1. A warp stop 4 is arranged in the limit seat 3. A rolling assembly for removing friction is arranged between the warp stop 4 and the warp threads 2. By setting the rolling assembly, no friction will be generated between the warp stop 4 and the warp threads 2, thereby avoiding the situation that the warp stop 4 is worn for a long time and the surface wears unevenly, which affects the warp threads 2, extending the time when the warp stop 4 needs to be replaced and prolonging its service life. The rolling assembly includes balls 5 arranged in the warp stop 4. A connecting piece 6 is fixedly connected to the bottom end of the warp stop 4. A roller 7 is arranged at the bottom end of the connecting piece 6. It also includes a top plate 8 arranged at the top end of the limit seat 3. A connecting assembly for quickly removing the top plate 8 is arranged between the top plate 8 and the limit seat 3. By setting the connecting assembly, the top plate 8 can be quickly removed, so as to take out the warp stop 4 and other components for maintenance or replacement.
[0028] As Figures 2 to 5As shown in the figure, specifically, a rotating shaft is fixedly connected in the warp stop motion 4, and the ball 5 is rotatably connected to the rotating shaft. There are two balls 5, and the vertical positions of the two balls 5 are staggered. A sliding groove 9 adapted to the ball 5 is formed in the limit seat 3, and the ball 5 is slidably connected in the sliding groove 9. The bottom end of the connecting piece 6 is fixedly connected with a connecting rod 10, and the connecting rod 10 is rotatably connected to the roller 7. The warp 2 is slidably connected to the roller 7. When the jacquard machine body 1 is working, the warp 2 is lifted upward by the roller 7 under the action of tension. The roller 7 pushes the connecting piece 6 at the top through the connecting rod 10, and the connecting piece 6 pushes the warp stop motion 4 at the top, so that the warp stop motion 4 moves upward. The ball 5 on the warp stop motion 4 rolls and rubs in the sliding groove 9 and rotates on the rotating shaft while moving upward. A long groove is formed in the connecting piece 6. The top end of the warp stop motion 4 is fixedly connected with a lifting handle 11. Until the warp stop motion 4 pushes the lifting handle 11 upward to contact the top plate 8 and then stops moving. At this time, the entire warp stop motion 4 is in a suspended state in the limit seat 3 under the support of the bottom warp 2. During the continuous movement of the warp 2, the warp 2 no longer rubs against the warp stop motion 4, but slides in the roller 7 and rolls and rubs with it. The friction between the warp 2 and the roller 7 replaces the friction between the warp 2 and the warp stop motion 4, so that the warp stop motion 4 is not affected by friction and surface wear occurs, avoiding the influence on the warp 2 caused by the surface wear of the warp stop motion 4. And the friction between the warp 2 and the roller 7 is rolling friction. Therefore, compared with the sliding friction between the warp 2 and the warp stop motion 4 in the traditional jacquard machine body 1, the friction force is greatly reduced, further enhancing the protection of the warp 2 and making the wear degree smaller. At the same time, the roller 7 is subjected to less friction force, enhancing the protection of itself and reducing the wear degree. At the same time, the warp stop motion 4 is restricted in the limit seat 3, and its position is not easy to move under the action of the warp 2. Compared with the traditional warp stop motion 4 installed on the warp 2, this installation method in the limit seat 3 restricts the movement of the warp stop motion 4, making it not easy to collide with surrounding components, reducing vibration and noise.
[0029] As Figures 2 to 5As shown, specifically, a carrier frame 12 is fixedly connected to the bottom end of the limit seat 3. A pressure sensor 13 is fixedly installed on the carrier frame 12, and a support plate 14 is fixedly connected to the top end of the pressure sensor 13. Path grooves 15 for the connecting piece 6 to move are formed on both the support plate 14 and the carrier frame 12. When the warp thread 2 breaks, the warp thread 2 no longer lifts the warp stop lever 4 through components such as the roller 7. Thus, the warp stop lever 4 and components such as the roller 7 move downward under their own gravity. The downward movement of the warp stop lever 4 drives the ball 5 to move downward. The downward movement of the ball 5 causes it to roll and have a rolling friction with the chute 9. The frictional force generated by the rolling friction is smaller than the sliding frictional force between the warp stop lever 4 and the limit seat 3. Therefore, the setting of the ball 5 is more conducive to the downward movement of the warp stop lever 4 under gravity. When the warp stop lever 4 moves downward to the top of the support plate 14, the self-gravity of the warp stop lever 4 exerts a pressure on the support plate 14, so that the pressure sensor 13 on the carrier frame 12 senses the pressure signal. Then the pressure sensor 13 transmits the signal to an external controller to control the jacquard loom body 1 to pause. At this time, the staff can observe which position of the roller 7 has dropped, so as to judge which position of the warp thread 2 has broken. After connecting the wire, the jacquard loom body 1 continues to work to move the warp thread 2, so as to lift the roller 7 and components such as the warp stop lever 4 upward again.
[0030] As Figure 1 , Figure 2 and Figure 6 shown, specifically, the connecting component includes a pull rod 16 slidably connected in the limit seat 3. A moving plate 17 is fixedly connected to the pull rod 16, and a spring 18 is fixedly connected between the moving plate 17 and the limit seat 3. A card slot 19 is formed on the protruding panel of the top plate 8, and the pull rod 16 is embedded in the card slot 19. An inclined surface is formed on the pull rod 16, and an inclined surface adapted to the inclined surface is provided at the bottom end of the protruding panel of the top plate 8. When the warp stop lever 4 and components such as the roller 7 need to be maintained and replaced, the pull rod 16 is pulled to drive the moving plate 17 to move, so that the spring 18 is stressed and contracts to generate a reaction force. The pull rod 16 moves out of the card slot 19 during the movement. Thus, the top plate 8 can be removed at this time. After the top plate 8 is removed, the pull rod 16 is released. The pull rod 16 moves back under the reaction force of the spring 18. After the top plate 8 is removed, the warp stop lever 4 and components such as the roller 7 can be moved upward through the path groove 15 by pulling the lifting handle 11. After the maintenance and replacement are completed, it is put back so that the ball 5 enters the chute 9 and the roller 7 is placed on the warp thread 2 again. Then the top plate 8 is put back and pressure is applied to it. Since an inclined surface is formed on the pull rod 16 and an inclined surface adapted to the inclined surface is provided at the bottom end of the protruding panel of the top plate 8, the pull rod 16 can be forced to move, and the spring 18 is stressed and contracts to generate a reaction force. Until the top plate 8 moves downward until the pull rod 16 is located at the card slot 19, the pull rod 16 enters the card slot 19 under the reaction force of the spring 18, thus completing the limit fixation of the top plate 8.
