Description

Technical Field

[0001] This utility model relates to the field of tension buffer devices, specifically a tension buffer device for a wire feeding machine. Background Technology

[0002] A wire-laying machine is an auxiliary device used in the production and processing of wires such as electric wires, cables, optical fibers, enameled wires, and fibers. Its main function is to continuously and stably release the wire from a reel or spool for use in subsequent processes. Based on application scenarios and functional requirements, wire-laying machines can be divided into powered wire-laying machines and passive wire-laying machines.

[0003] Existing wire feeding machines lack a buffer device during wire feeding, which can cause wires to fall off or become tangled when the wire feeding is too fast or too slow, thus reducing the quality of the wire feeding.

[0004] Therefore, a tension buffer device for a wire feeding machine is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Preferably, the adjusting rod has a groove on the side near the steel cable; the groove is provided with multiple counterweights; through the cooperation of the groove and the counterweights, the tension spring can be coarsely adjusted by placing the counterweights, thereby improving the convenience of the device in adjusting the tension of the wire harness.

[0008] Preferably, a fixed pulley is fixedly connected to the side of the frame near the first cantilever plate; the steel cable and the fixed pulley are in contact; by setting the fixed pulley, the steel cable will be subject to the additional guiding effect applied by the fixed pulley when moving, reducing the possibility of the steel cable contacting other components due to its excessive length when moving.

[0009] Preferably, the rotating part and the first cantilever plate have multiple positioning holes on their surfaces; the positioning holes are arranged in a circumferential array; by setting multiple positioning holes, after the tension of the tension spring is finely adjusted by the screw, the rotating part can be fixed by inserting a pin through the positioning holes inside the first cantilever plate and the rotating part, so that when the first guide wheel is squeezed by the wire harness, the screw will not rotate under the pulling action of the steel cable, thus improving the stability of the screw.

[0010] Preferably, a plurality of connecting rods are fixedly connected to the outer wall of the second pick plate; the connecting rods and the second guide wheel are correspondingly arranged; a spring telescopic rod is fixedly connected to the end of the connecting rod; a connecting frame is fixedly connected to the bottom of the spring telescopic rod; a third guide wheel is rotatably connected inside the connecting frame, and the inner wall of the third guide wheel has a V-shaped structure; the third guide wheel is located on one side of the second guide wheel; through the cooperation of the third guide wheel and the spring telescopic rod, the spring telescopic rod will apply elastic force to the connecting frame and the third guide wheel so that they can fit tightly against the outer wall of the second guide wheel and place the wire harness between the third guide wheel and the second guide wheel. Since the inner wall of the third guide wheel has a V-shaped structure, the wire harness can receive additional guiding action when being laid out, reducing the deviation that occurs when the wire harness is laid out and improving the stability of the device when laying out the wire harness.

[0011] Preferably, a sponge is fixed to the inner wall of the third guide wheel; the surface of the sponge has an arc-shaped structure; by setting the sponge, when the wire harness comes into contact with the third guide wheel, the sponge on the third guide wheel will also come into contact with the wire harness and scrape off the dust attached to the surface of the wire harness, thereby achieving the cleaning of the wire harness during wire harness unloading and improving the smoothness of the wire harness surface.

A connecting plate 16 is rotatably connected to the top of the frame 1; the connecting plate 16 and the steel cable 110 are fixedly connected; a rotating part 15 is fixedly connected to the bottom of the screw 14; a second cantilever plate 111 is fixedly connected to the other side of the frame 1; a pair of second guide wheels 112 are rotatably connected to the surface of the second cantilever plate 111; the second guide wheels 112 are located above the wire feeding machine 12; during operation, the wire bundle wound on its surface can be fed out by the motor set on the wire feeding machine 12, specifically by passing the wire bundle through the second guide wheel 112 and the first guide wheel 18 in sequence, and then fixing its end. The wire is then fixed onto another roller, and the wire feeding machine 12 can be started to feed the wire bundle. During the process, the tension of the tension spring 19 on the adjusting rod 17 can be adjusted according to the feeding speed. Specifically, by rotating the rotating part 15, the screw 14 moves vertically along the first pick plate 13. During this process, the connecting plate 16 moves vertically along with the screw 14, and the steel cable 110 pulls or releases one end of the adjusting rod 17 as the connecting plate 16 moves. The adjusting rod 17 rotates accordingly with the force of the steel cable 110, causing the tension spring 19 to... Corresponding tensile deformation will also occur to ensure the tension applied to the adjusting rod 17. The tension applied to the adjusting rod 17 by the tension spring 19 makes the tension of the first guide wheel 18 controllable during wire harness feeding, ensuring that the wire harness can be stably fed by the feeding machine 12. The tension of the tension spring 19 on the adjusting rod 17 can be adjusted by rotating the screw 14, realizing the adjustable tension compression between the first guide wheel 18 and the wire harness, so that the wire harness can be kept in a taut state whether the feeding speed is too fast or too slow, improving the quality and stability of the device when feeding the wire harness.

[0025] Please see Figure 3As shown, the adjusting rod 17 has a groove 2 on the side near the steel cable 110; the groove 2 has multiple counterweights 22 inside; through the cooperation of the groove 2 and the counterweights 22, when adjusting the tension of the tension spring 19 on the adjusting rod 17, an appropriate number of counterweights 22 can be placed into the groove 2 first, so that a certain pressure is applied to the side of the adjusting rod 17 near the steel cable 110 in advance. Then, the rotation angle of the adjusting rod 17 and the tension applied by the tension spring 19 can be finely adjusted by rotating the screw 14 through the steel cable 110; through the cooperation of the groove 2 and the counterweights 22, the tension of the tension spring 19 can be coarsely adjusted by placing the counterweights 22, improving the convenience of the device in adjusting the tension of the wire harness.

[0026] Please see Figure 3 As shown, a fixed pulley 3 is fixedly connected to the side of the frame 1 near the first cantilever plate 13; the steel cable 110 and the fixed pulley 3 are in contact; by setting the fixed pulley 3, the steel cable 110 will be subject to the additional guiding effect applied by the fixed pulley 3 when it moves, reducing the situation where the steel cable 110 comes into contact with other components due to its excessive length when it moves.

[0027] Please see Figure 3 As shown, the rotating part 15 and the first pick plate 13 are provided with a plurality of positioning holes 4; the positioning holes 4 are arranged in a circumferential array; by providing a plurality of positioning holes 4, after the tension of the tension spring 19 is finely adjusted by the screw 14, the rotating part 15 can be fixed by inserting a pin through the positioning holes 4 inside the first pick plate 13 and the rotating part 15, so that when the first guide wheel 18 is squeezed by the wire harness, the screw 14 will not rotate under the pulling action of the steel cable 110, thereby improving the stability of the screw 14.

[0028] Please see Figure 4 and Figure 5 As shown, multiple connecting rods 5 are fixed to the outer wall of the second pick plate 111; the connecting rods 5 and the second guide wheel 112 are correspondingly arranged; a spring telescopic rod 52 is fixed to the end of the connecting rod 5; a connecting frame 53 is fixed to the bottom of the spring telescopic rod 52; a third guide wheel 54 is rotatably connected inside the connecting frame 53, and the inner wall of the third guide wheel 54 has a V-shaped structure; the third guide wheel 54 is located on one side of the second guide wheel 112; through the cooperation of the third guide wheel 54 and the spring telescopic rod 52, the spring telescopic rod 52 will apply elastic force to the connecting frame 53 and the third guide wheel 54 so that they can be tightly attached to the outer wall of the second guide wheel 112 and the wire harness is between the third guide wheel 54 and the second guide wheel 112. Since the inner wall of the third guide wheel 54 has a V-shaped structure, the wire harness can receive additional guidance when it is being laid out, reducing the deviation that occurs when the wire harness is laid out and improving the stability of the device when laying out the wire harness.

[0029] Please see Figure 5As shown, a sponge 6 is fixed to the inner wall of the third guide wheel 54; the surface of the sponge 6 is an arc-shaped structure; by setting the sponge 6, when the wire harness comes into contact with the third guide wheel 54, the sponge 6 on the third guide wheel 54 will also come into contact with the wire harness and scrape off the dust attached to the surface of the wire harness, thereby achieving the cleaning of the wire harness during wire feeding and improving the smoothness of the wire harness surface.

[0030] Working principle: The wire harness wound on the surface of the wire feeding machine 12 is fed out by a motor. Specifically, the wire harness passes through the second guide wheel 112 and the first guide wheel 18 in sequence, and its end is fixed to another roller. Then, the wire feeding machine 12 can be started to feed out the wire harness. During the process, the tension of the tension spring 19 on the adjusting rod 17 can be adjusted according to the feeding speed. Specifically, by rotating the rotating part 15, the screw 14 moves vertically along the first pick plate 13. During the process, the connecting plate 16 moves vertically along with the screw 14, and the steel cable 110 pulls or releases one end of the adjusting rod 17 as the connecting plate 16 moves. The adjusting rod 17 moves with the steel cable 110. The force applied by screw 10 causes corresponding rotation, resulting in a corresponding stretching deformation of tension spring 19, ensuring the tension applied to adjusting rod 17. Through the tension applied by tension spring 19 to adjusting rod 17, the tension of first guide wheel 18 during wire harness feeding is controllable, ensuring stable feeding of the wire harness by feeding machine 12. Through the cooperation of groove 2 and counterweight 22, when adjusting the tension of tension spring 19 on adjusting rod 17, an appropriate number of counterweights 22 can be placed into groove 2 to pre-apply a certain pressure to the side of adjusting rod 17 closest to steel cable 110. Subsequently, the rotation angle and tension of adjusting rod 17 can be adjusted by rotating screw 14 via steel cable 110. The tension of the tension spring 19 is finely adjusted; by setting a fixed pulley 3, the steel cable 110 is given additional guiding action when moving, reducing the possibility of the steel cable 110 contacting other components due to its excessive length; by setting multiple positioning holes 4, after the tension of the tension spring 19 is finely adjusted by the screw 14, the rotating part 15 can be fixed by a pin passing through the positioning holes 4 inside the first cantilever plate 13 and the rotating part 15, so that when the first guide wheel 18 is squeezed by the wire harness, the screw 14 will not rotate under the pulling action of the steel cable 110, thus improving the stability of the screw 14; by the third guide wheel 54 and the spring telescopic rod 52 In conjunction with the spring telescopic rod 52, the connecting frame 53 and the third guide wheel 54 are subjected to elastic force, which allows them to fit tightly against the outer wall of the second guide wheel 112 and position the wire harness between the third guide wheel 54 and the second guide wheel 112. The inner wall of the third guide wheel 54 has a V-shaped structure, which provides additional guidance for the wire harness during wire feeding, reducing the deviation that occurs during wire feeding and improving the stability of the device during wire feeding. By setting the sponge 6, when the wire harness comes into contact with the third guide wheel 54, the sponge 6 on the third guide wheel 54 also comes into contact with the wire harness and scrapes off the dust adhering to the surface of the wire harness, thus achieving the cleaning of the wire harness during wire feeding and improving the smoothness of the wire harness surface.
