The electronic jacquard special machine has multiple loop forming systems, high speed, high output, fast pattern change, good fabric quality, fewer processes, and strong product adaptability, so it develops rapidly.

[0003] The existing positioning device of the electronic jacquard machine is generally fixedly installed at the yarn feeder, but the textile thread may break due to friction at the through hole of the positioning device. When the textile thread breaks, the textile thread will rebound due to tension. When repairing, the staff needs to pass the textile thread through the loom, yarn feeder and positioning device hole again. The yarn sections are easy to get tangled and knotted, and the broken yarn part needs to be found at a close distance.

[0004] Therefore, a special electronic jacquard machine with a positioning mechanism is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an electronic jacquard machine with a positioning mechanism to solve the problems raised in the above background technology.

[0016] Beneficial effects of the utility model:

[0017] 1. The utility model designs a positioning mechanism. The yarn tension can compress the first spring, push the push rod to move backward, and the connecting rod rotates clockwise to pull the hinged rod forward to disconnect the two electrodes on the switch. Conversely, when the yarn breaks, the first spring releases the elastic force, the metal block moves backward to connect the two electrodes on the switch, and the machine alarms, which can quickly and accurately locate the yarn outlet mechanism where the yarn is broken.

[0018] 2. The utility model designs a clamping mechanism. When the yarn breaks, the tension is lost and the alarm mechanism is triggered. The compressed first spring releases the elastic force to push the clamp as a whole to move forward. After the inner wall of the positioning detector fits against the pad, it is squeezed and pushes the clamp to move to the right. The space of the wire groove is reduced so that the yarn can be clamped to prevent the yarn from being entangled with other yarns after breaking. The staff can quickly connect the yarn and continue to operate the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 5 As shown, the specific embodiment of the utility model provides an electronic jacquard special machine with a positioning mechanism, including a jacquard machine body 1, a fixing frame 2 is arranged at the upper end of the jacquard machine body 1, a plurality of positioning detectors 4 and an alarm light 5 are arranged at the upper end of the fixing frame 2, and a sand discharge mechanism 3 is arranged correspondingly at the upper end of the positioning detector 4;

[0029] The positioning mechanism includes a control frame 13 disposed inside the positioning detector 4, a metal block 14 is disposed at the upper end of the control frame 13, and a switch 15 is disposed at the rear end of the metal block 14;

[0030] The clamping mechanism includes a wire clamp 19 and a rotating wheel 20 arranged at the front end of the positioning detector 4, a wire groove 24 is arranged between the wire clamp 19 and the rotating wheel 20, a support rod 22 is arranged inside the wire groove 24, and a third spring 21 is sleeved on the outer side of the support rod 22.

[0031] By adopting the above technical scheme, the utility model is designed with a positioning mechanism and a clamping mechanism. The positioning mechanism can be combined with the opening and closing of the yarn tension control switch 15, so as to facilitate employees to identify the normal operation of the machine. The clamping mechanism can control the left and right movement of the clamp 19 through the yarn tension, thereby reducing the size of the wire groove 24 and clamping the yarn when the yarn breaks.

[0032] Specifically, Figures 3 to 5As shown, grooves are provided on the left and right sides of the front end of the positioning detector 4, a slider 6 is slidably connected inside the groove on the left side, a bearing 23 is rollingly connected inside the groove on the right side, a support rod 22 is fixedly connected inside the bearing 23, the left end of the support rod 22 is fixedly connected to the right side of the slider 6, two groups of guide rods 7 are arranged throughout the inside of the slider 6, the guide rods 7 are fixedly connected to the positioning detector 4, a push rod 9 is arranged throughout the left end of the positioning detector 4, the push rod 9 is horizontally arranged between the two groups of guide rods 7, the front end of the push rod 9 is fixedly connected to the rear end of the slider 6, the rear end of the slider 6 is provided with a first spring 8, the first spring 8 is sleeved on the outside of the push rod 9, A connecting rod 10 is provided at the rear end of the rod 9, and the right end of the connecting rod 10 is rotatably connected to the upper part of the fixed seat 12, and the fixed seat 12 is fixedly connected to the inside of the positioning detector 4. A control frame 13 is also provided inside the positioning detector 4. The left side of the control frame 13 is slidably connected to the hinged rod 11, and the front end of the hinged rod 11 is rotatably connected to the connecting rod 10. The front end of the hinged rod 11 is slidably connected to the outside of the sliding rod 16, and the sliding rod 16 is fixedly connected to the left side of the control frame 13 and is sleeved with a second spring 17. A switch 15 is provided at the upper end of the control frame 13, and the switch 15 is adapted for use with the metal block 14, and the metal block 14 is fixedly connected to the front end of the hinged rod 11.

[0033] By adopting the above technical scheme, the yarn at the lower end of the sand discharge mechanism 3 is passed through the inside of the wire groove 24. During the normal weaving process of the machine, the yarn has a certain tension, and its tension acts on the wire groove 24, driving the support rod 22 to slide to the rear end, and the push rod 9 moves to the rear end with the support rod 22 and pushes the connecting rod 10 to rotate, pulling the hinged rod 11 to move backward to separate the metal block 14 and the switch 15, and the machine operates normally. When the yarn breaks, due to insufficient tension, the compressed first spring 8 releases the elastic force to push the slider 6 to slide forward, and the push rod 9 moves forward with the slider 6. Without the thrust of the push rod 9, the second spring 17 compressed by the clockwise rotation of the connecting rod 10 releases the elastic force, pushing the hinged rod 11 to move backward, and the metal block 14 and the switch 15 are attached. After the two electrodes are energized, the alarm light 5 turns red and the machine stops running, which is conducive to workers quickly finding problems when guarding the machine and accurately locating which part of the yarn is broken, thereby improving production efficiency.

[0034] Specifically, Figure 2 and Figure 3 As shown, a wire clamp 19 is provided at the front end of the positioning detector 4, a through hole is opened on the right side of the wire clamp 19, the size of the through hole is adapted to the wire groove 24, the wire groove 24 is provided on the left side of the rotating wheel 20, the rotating wheel 20 is rotatably connected to the outer side of the support rod 22, the middle part of the support rod 22 is fixedly connected to a limit plate, the left end of the limit plate is provided with a third spring 21, the third spring 21 is sleeved on the outer side of the support rod 22, the outer side of the support rod 22 is slidably connected with the wire clamp 19, and a pad 18 is provided on the left side of the wire clamp 19.

[0035] By adopting the above technical solution, at the moment the yarn breaks, the first spring 8 compressed due to the tension releases the elastic force, pushing the slider 6 to move forward, and when the pad 18 fits against the side wall of the positioning detector 4, the clamp 19 moves to the right side due to extrusion to fit against the rotating wheel 20, so that the yarn inside the wire groove 24 is clamped. When the yarn is connected and the tension is restored, the clamp 19 is always kept on the left side under the push of the elastic force of the third spring 21, which is beneficial to prevent the yarn from being mixed with other yarns after breaking, and is convenient for the staff to quickly connect the broken yarn.

[0036] Working principle: The yarn at the lower end of the sand discharge mechanism 3 is passed through the inside of the wire groove 24. During the normal weaving process of the machine, the yarn has a certain tension, and its tension acts on the wire groove 24, driving the support rod 22 to slide to the rear end, and the push rod 9 moves to the rear end with the support rod 22 and pushes the connecting rod 10 to rotate, pulling the hinged rod 11 to move backward to separate the metal block 14 and the switch 15, and the machine operates normally. When the yarn breaks, due to insufficient tension, the compressed first spring 8 releases the elastic force to push the slider 6 to slide forward, and the push rod 9 moves forward with the slider 6. Without the thrust of the push rod 9, the second spring 17 compressed by the clockwise rotation of the connecting rod 10 releases the elastic force, pushing the hinged rod 11 to move backward, and the metal block 14 and the switch 15 are attached. After the two electrodes are energized, the alarm light 5 lights up red and the machine stops running, which is conducive to workers quickly discovering problems when guarding the machine and accurately locating which part of the yarn is broken, thereby improving production efficiency;

[0037] At the moment the yarn breaks, the first spring 8 compressed due to tension releases its elastic force, pushing the slider 6 forward. When the pad 18 fits against the side wall of the positioning detector 4, the wire clamp 19 moves to the right to fit against the rotating wheel 20 due to extrusion, so that the yarn inside the wire groove 24 is clamped. When the yarn is connected and the tension is restored, the wire clamp 19 is always kept on the left side under the push of the elastic force of the third spring 21, which helps prevent the yarn from being mixed with other yarns after breaking and facilitates the staff to quickly connect the broken yarn.
