Description

Technical Field

[0001] This utility model belongs to the field of electrical transmission technology, specifically relating to an energy-saving servo motor for jacquard machines. Background Technology

[0002] Jacquard machines are key equipment in the textile industry used for weaving complex patterned fabrics. Energy-saving jacquard machines use servo motors as important drive components, and their performance directly affects the machine's automation level, production efficiency, and product quality. They are closely integrated with the overall design of textile machinery, weaving processes, and automated control systems, serving as a crucial support for the development of textile machinery automation technology.

[0003] In some existing energy-saving jacquard machines, the servo motors often suffer from the problem of wires coming loose due to the high-frequency vibrations generated during operation. During the operation of the jacquard machine, the servo motor is responsible for precisely controlling the formation of the fabric's pattern. If the wires come loose, it will directly lead to malfunction of the motor control, causing the movement of components such as the knitting needles and shuttles to be unable to follow the preset program. This results in quality problems such as disordered patterns, incomplete designs, and uneven weft threads, which in turn leads to an increase in the product defect rate. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving servo motor for jacquard machines, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy-saving servo motor for a jacquard machine includes a servo motor body, a motor housing, an output shaft, and a wire plugged into the wiring port of the motor housing.

[0007] The wiring mechanism includes a wire clamping assembly for clamping the wire, which is located outside the wiring port of the motor housing;

[0008] The wire clamping assembly includes an internally threaded cylinder fixedly connected to the outside of the motor housing terminal, an externally threaded cylinder threadedly connected to the inner surface of the internally threaded cylinder, a tapered opening on the inner wall of the externally threaded cylinder, a plurality of elastic blocks fixedly connected to the inner wall of the internally threaded cylinder and used to clamp the wire, and a force-receiving end fixedly connected to the outer end face of the elastic block and cooperating with the tapered opening to drive the elastic block to tighten.

[0009] An energy storage component, located outside the wiring mechanism, is used to store elastic potential energy for resetting during the clamping process of the wire clamping assembly.

[0010] As a preferred embodiment of this utility model, a plurality of elastic blocks are arranged in a circumferential array on the inner wall of the internally threaded cylinder. When the conical opening contacts the force-bearing end, it can drive the plurality of elastic blocks to tighten inward simultaneously.

[0011] As a preferred embodiment of this utility model, the energy storage component includes a rotating rod fixedly mounted on the outer surface of the internal threaded cylinder via a bearing, a toothed column fixedly sleeved on the outer surface of the rotating rod, a toothed disc meshing with the outer surface of the toothed column and used in conjunction with the external threaded cylinder, a first torsion spring sleeved on the outer side of the internal threaded cylinder, and a fixing block fixedly connected to the outer surface of the internal threaded cylinder and used to support the first torsion spring.

[0012] As a preferred embodiment of this utility model, a rotating bearing sleeve is installed at the connection between the rotating rod and the fixed block, the outer end face of the first torsion spring is fixedly connected to the outer end face of the toothed column, and its other end is fixedly connected to the outer surface of the fixed block.

[0013] As a preferred embodiment of the present invention, the wiring mechanism further includes a limiting component that cooperates to ensure that the first torsion spring can release its elastic potential energy only when the wire is removed, which is located on the outside of the internal threaded cylinder.

[0014] As a preferred embodiment of this utility model, the limiting component includes a swivel fixedly connected to the outer surface of the internal threaded cylinder, a pawl rotatably sleeved on the outer surface of the swivel, a ratchet fixedly sleeved on the outer surface of the rotating rod and used in conjunction with the pawl, and a second torsion spring sleeved on the outside of the swivel and used in conjunction with the pawl.

[0015] In a preferred embodiment of this utility model, the pawl and the ratchet engage, the outer end face of the second torsion spring is fixedly connected to the outer surface of the pawl, and its other end is fixedly connected to the outer surface of the swivel column.

[0016] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of various components in the wiring mechanism, the wire can be firmly clamped when the jacquard machine is in use, preventing the wire from falling off due to the high-frequency vibration of the jacquard machine. During the clamping process, the first torsion spring is driven to twist and store energy. When removing the wire, it is only necessary to move the pawl to the position where it is no longer in contact with the ratchet, and the energy can be released by the first torsion spring to assist in loosening the wire clamping assembly. This achieves the effect of ensuring the accuracy of the servo motor body control while reducing the difficulty and time cost of removing the wire. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1-5 This is an embodiment of the present invention, which provides an energy-saving servo motor for a jacquard machine, comprising:

[0029] The servo motor body 100 includes a motor housing 110, an output shaft 120, and a wire 130 that is plugged into the wiring port of the motor housing 110.

[0030] It should be noted that the motor housing 110 provides physical protection for the windings, iron core, etc. inside the servo motor body 100, preventing them from being corroded by external environmental factors such as dust and moisture. At the same time, it provides a mounting base for the output shaft 120 and the wiring port, ensuring the stability of the overall structure of the motor. The output shaft 120 is used to transmit the rotational mechanical energy of the servo motor body 100 to the jacquard machine, driving the knitting needles, shuttles, and other actuators of the jacquard machine to realize the weaving action of the fabric pattern. The wire 130 is responsible for transmitting electrical energy, introducing the electrical energy of the external power supply into the servo motor body 100, providing power support for the operation of the servo motor body 100, and also used to transmit control signals so that the servo motor body 100 can operate accurately according to the preset program.

[0031] The wiring mechanism 200 includes a wire clamping assembly 210 for clamping the wire 130, which is located outside the wiring port of the motor housing 110.

[0032] The wire clamping assembly 210 includes an internally threaded cylinder 211 fixedly connected to the outside of the wiring port of the motor housing 110, an externally threaded cylinder 212 threadedly connected to the inner surface of the internally threaded cylinder 211, a tapered opening 213 opened on the inner wall of the externally threaded cylinder 212, a plurality of elastic blocks 214 fixedly connected to the inner wall of the internally threaded cylinder 211 and used to clamp the wire 130, and a force-receiving end 215 fixedly connected to the outer end face of the elastic block 214 and cooperating with the tapered opening 213 to drive the elastic block 214 to tighten.

[0033] It should be noted that the internal threaded cylinder 211 is used to provide an installation position for the external threaded cylinder 212 and the elastic block 214. The wire 130 is inserted into the terminal, and then the external threaded cylinder 212 is screwed into the internal threaded cylinder 211. The tapered opening 213 on its inner wall can squeeze the force-bearing end 215. The force-bearing end 215 drives the elastic block 214 to contract. The elastic block 214 tightens and clamps the wire 130 inward. The elastic block 214 can also use its own elastic force to automatically return to the initial position when the external threaded cylinder 212 is screwed out.

[0034] An energy storage component 220 is located outside the wiring mechanism 200 and is used to store elastic potential energy for reset during the clamping of the wire 130 by the clamping assembly 210.

[0035] Specifically, a number of elastic blocks 214 are arranged in a circumferential array on the inner wall of the internally threaded cylinder 211. When the conical opening 213 and the force-bearing end 215 come into contact, they can drive the elastic blocks 214 to tighten inward simultaneously.

[0036] Furthermore, the energy storage component 220 includes a rotating rod 221 fixedly mounted on the outer surface of the internal threaded cylinder 211 via a bearing, a toothed post 222 fixedly sleeved on the outer surface of the rotating rod 221, a toothed disc 223 meshing with the outer surface of the toothed post 222 and used in conjunction with the external threaded cylinder 212, a first torsion spring 224 sleeved on the outside of the internal threaded cylinder 211, and a fixing block 225 fixedly connected to the outer surface of the internal threaded cylinder 211 and used to support the first torsion spring 224.

[0037] Preferably, a rotating bearing sleeve is installed at the connection between the rotating rod 221 and the fixing block 225, the outer end face of the first torsion spring 224 is fixedly connected to the outer end face of the toothed column 222, and its other end is fixedly connected to the outer surface of the fixing block 225.

[0038] It should also be noted that rotating the lever 221 can drive the toothed column 222 and ratchet 233 to rotate synchronously. The toothed column 222 drives the toothed disc 223 and the external threaded cylinder 212 to rotate synchronously. At the same time, the lever 221 drives the first torsion spring 224 to store torsion energy through rotation, so that the first torsion spring 224 can release rotational energy to assist in loosening the wire clamping assembly 210 when the wire 130 is removed. The fixing block 225 is used to provide a fixed end for the first torsion spring 224 to ensure that its energy storage and release process is stable.

[0039] It should be noted that the wiring mechanism 200 also includes a limiting component 230 located on the outside of the internal threaded cylinder 211, which cooperates to ensure that the first torsion spring 224 can release its elastic potential energy only when the wire 130 is removed.

[0040] Furthermore, the limiting assembly 230 includes a rotating post 231 fixedly connected to the outer surface of the internal threaded cylinder 211, a pawl 232 rotatably sleeved on the outer surface of the rotating post 231, a ratchet 233 fixedly sleeved on the outer surface of the rotating rod 221 and used in conjunction with the pawl 232, and a second torsion spring 234 sleeved on the outside of the rotating post 231 and used in conjunction with the pawl 232.

[0041] It should be explained that the rotating column 231 provides an installation position for the pawl 232 and the second torsion spring 234. The pawl 232 is used to limit the rotation direction of the ratchet 233 and the rotating rod 221, so that the rotating rod 221 can only rotate in one direction, thereby preventing the first torsion spring 224 from releasing energy. When the wire 130 is removed, the pawl 232 is moved to the position where it is disengaged from the ratchet 233, so that the ratchet 233 is reset by the reaction force of the first torsion spring 224 along with the rotating rod 221. The second torsion spring 234 is used to provide a reset elastic force for the pawl 232, so that it remains engaged with the ratchet 233.

[0042] Specifically, the pawl 232 and the ratchet 233 are engaged, the outer end face of the second torsion spring 234 is fixedly connected to the outer surface of the pawl 232, and its other end is fixedly connected to the outer surface of the swivel column 231.

[0043] When using,

[0044] Insert wire 130 into the wiring port of motor housing 110 to transmit electrical energy and control signals, so that the servo motor body 100 runs according to the preset program.

[0045] Next, rotating the lever 221 drives the toothed column 222 and ratchet 233 to rotate synchronously. The toothed column 222 drives the toothed disc 223 to rotate, and the toothed disc 223 drives the external threaded cylinder 212 to screw into the internal threaded cylinder 211. The tapered opening 213 on the inner wall of the external threaded cylinder 212 squeezes the force-bearing end 215 on the outer end face of the elastic block 214, causing several elastic blocks 214 to tighten inward at the same time, clamping the wire 130 and preventing it from falling off due to the vibration of the jacquard machine.

[0046] During the clamping process: while the rotating rod 221 drives the first torsion spring 224 to twist and store energy, it also drives the ratchet 233 to squeeze the pawl 232. The second torsion spring 234 ensures that the pawl 232 and the ratchet 233 remain engaged, thereby limiting the rotation direction of the rotating rod 221 and preventing the first torsion spring 224 from accidentally releasing energy.

[0047] When removing wire 130: move pawl 232 to a position where it is no longer in contact with ratchet 233, and release energy through first torsion spring 224 to help loosen wire clamp assembly 210.

[0048] In summary, through the cooperation of the various components in the wiring mechanism 200, the wire 130 can be firmly clamped during the use of the jacquard machine, preventing the wire 130 from falling off due to the high-frequency vibration of the jacquard machine. During the clamping process, the first torsion spring 224 is driven to twist and store energy. When removing the wire 130, it is only necessary to move the pawl 232 to the position where it is disengaged from the ratchet 233, and the energy can be released by the first torsion spring 224 to assist in loosening the wire clamping assembly 210. This achieves the effect of ensuring the accuracy of the control of the servo motor body 100 while reducing the difficulty and time cost of removing the wire 130.
