Description

Technical Field

[0001] The present invention relates to the field of cable winding, and particularly to a winding device for power detection. Background Art

[0002] To facilitate the transportation and sale of the produced cables, it is necessary to wind the cables onto a winding wheel so that the cables are wound into independent coils. During the winding process of cables of the same length, the tightness of the cable winding determines the size and neatness of the coil. The tightly wound cables reduce the probability of the cables becoming loose during transportation. During the cable processing and production process, to ensure the insulation of the cables, an insulating jacket is added outside the conductor, and the flame retardancy of the insulating jacket must be ensured to improve the safety during the use of the cables. Existing cables often use low-smoke and halogen-free wire sheaths, which are composed of thermoplastic or thermosetting plastics with low smoke emission when heated and no halogen in themselves. After adding a low-smoke and halogen-free protective sleeve outside the conductor, qualified cables are formed.

[0003] When winding cables, a winding device is required. However, the existing cable winding devices cannot provide a stable resistance when winding cables, resulting in the situation of loose cable winding. It is not convenient to wind the cables neatly on the winding disc, and when continuing to wind, it will be sandwiched between the loose cables of the next layer, eventually leading to misalignment and other situations, resulting in cable winding during the subsequent wire feeding process, and the loose coils are prone to uncoiling during transportation. Summary of the Invention

[0004] The present invention provides a winding device for power detection to solve the problem that the existing cable winding devices do not wind the cables tightly.

[0012] Further, a limiting groove is arranged on the slider, the limiting groove is parallel to and spaced from the first slideway, a plurality of limiting blocks are arranged in the limiting groove, the plurality of limiting blocks are spaced apart, and each limiting block can slide along the depth direction of the limiting groove; a second elastic member is arranged between the top pressing rod and the end of the first slideway, and the second elastic member urges the top pressing rod to approach the winding wheel; a convex block is fixedly arranged on the top pressing rod, the convex block slides along the limiting groove, and the limiting block prevents the convex block from approaching the winding wheel.

[0013] The beneficial effects of the present invention are as follows: A winding device for power detection of the present invention includes a fixing frame, a winding wheel, a detection component, and a pressing component. One end of the cable is fixed in the locking hole, and the winding wheel is driven to rotate by a power source.

[0020] An embodiment of a winding device for power detection of the present invention is as follows Figures 1 to 7 As shown, it includes a fixing frame, a winding wheel 120, a detection component and a tightening component.

[0021] The fixing frame includes a base plate 111 and a support plate 112. The base plate 111 is horizontally arranged. The support plate 112 is fixed by a connecting rod and is arranged parallel to the base plate 111. Three groups of brackets are fixedly arranged on the base plate 111. The three groups of brackets are divided into a first bracket 113, a second bracket 114 and a third bracket 115 from left to right, and the third bracket 115 is provided with a mounting groove 116 opening upward.

[0022] The winding wheel 120 has a first axis, which is horizontally arranged. The winding wheel 120 extends forward and backward. Limit plates 130 are fixedly arranged at both ends of the winding wheel 120. The limit plates 130 are coaxially arranged with the winding wheel 120. The diameter of the limit plates 130 limits the maximum diameter of the cable that can be wound on the winding wheel 120. The end of the peripheral side wall of the winding wheel 120 is provided with a locking hole opening outward. When winding the cable, one end of the cable is first inserted into the locking hole. The rotating shaft of the winding wheel 120 is rotatably arranged in the mounting groove 116 of the third bracket 115, so that the cable can be easily disassembled after winding on the winding wheel 120. A first transmission wheel 140 is fixedly arranged on the rotating shaft of the winding wheel 120. A support plate 160 is fixedly provided on the front side wall of the third bracket 115, and the support plate 160 is horizontally arranged. A motor 170 is fixedly provided on the upper end surface of the support plate 160, and a second transmission wheel 150 is fixedly provided on the power output shaft of the motor 170. The second transmission wheel 150 and the first transmission wheel 140 are arranged with an interval up and down, and the second transmission wheel 150 and the first transmission wheel 140 are connected through a transmission belt 180. When the motor 170 rotates, the winding wheel 120 rotates around the first axis.

[0023] The detection component includes a detection plate 210 and a telescopic rod 220. The detection plate 210 is horizontally arranged and is disposed above the winding wheel 120. The length of the detection plate 210 is the same as that of the winding wheel 120. The telescopic rod 220 is vertically arranged. The lower end of the telescopic rod 220 is fixedly arranged on the detection plate 210, and the upper end of the telescopic rod 220 is fixedly arranged on the support plate 112. A first elastic member is arranged inside the telescopic rod 220, and the first elastic member is a first spring. In the initial state, the first spring is in the original length state, and the telescopic rod 220 is in the longest state, so that the distance between the detection plate 210 and the side wall of the winding wheel 120 is less than the diameter of the cable. During the winding process of the cable, the cable is arranged between the detection plate 210 and the side wall of the winding wheel 120. The cable is always squeezed by the detection plate 210 during the winding process on the winding wheel 120, so that the cables are closely arranged in the radial direction of the winding wheel 120. When the thickness of the cable wound on the winding wheel 120 increases, the cable pushes the detection plate 210 to move upward, and the detection plate 210 squeezes the first spring. When the detection plate 210 moves upward, the transmission ratio of the motor 170 driving the winding wheel 120 to rotate is adjusted through the speed change component.

[0024] In this embodiment, the speed change component includes an adjustment plate 310. The first transmission wheel 140 is frustum-shaped. The end with a smaller diameter of the first transmission wheel 140 is fixedly arranged on the rotating shaft of the winding wheel 120, so that the end with a larger diameter of the first transmission wheel 140 is on the front side of the end with a smaller diameter. The second transmission wheel 150 is frustum-shaped, and the size of the second transmission wheel 150 is the same as that of the first transmission wheel 140. The end with a smaller diameter of the second transmission wheel 150 is fixedly arranged on the power output shaft of the motor 170, so that the end with a smaller diameter of the second transmission wheel 150 is on the front side of the end with a larger diameter. The second transmission wheel 150 and the first transmission wheel 140 are arranged up and down. A third slideway 117 extending in the front-rear direction is arranged on the upper right end surface of the bottom plate 111, and the third slideway 117 is arranged parallel to the first axis. The adjustment plate 310 is a rectangular plate structure. The adjustment plate 310 is vertically arranged. The lower end of the adjustment plate 310 is slidably arranged along the third slideway 117. A switching plate 320 is fixedly arranged in the middle of the adjustment plate 310. The switching plate 320 is horizontally arranged and extends left and right. A switching slot 321 penetrating up and down is arranged on the switching plate 320. The middle part of the transmission belt 180 is arranged in the switching slot 321. When the adjustment plate 310 slides back and forth along the third slideway 117, it drives the transmission belt 180 to move back and forth, so that the positions where the transmission belt 180 is connected to the first transmission wheel 140 and the second transmission wheel 150 are changed, and thus the transmission ratio between the first transmission wheel 140 and the second transmission wheel 150 is changed.

[0025] A pushing component is arranged between the detection plate 210 and the adjustment plate 310. When the detection plate 210 gradually moves upward, the adjustment plate 310 slides along the third slideway 117 to change the transmission ratio between the first transmission wheel 140 and the second transmission wheel 150. Specifically, the pushing component includes a pushing bent rod 330 and a fixed block 340. The fixed block 340 is in the shape of a right trapezoidal plate, the length of the upper base of the fixed block 340 is greater than the length of the lower base, the lower base of the fixed block 340 is fixedly connected to the upper end of the adjustment plate 310, and the right-angled side of the fixed block 340 is on the same straight line as the front side edge of the adjustment plate 310, so that the fixed block 340 has an inclined second inclined surface, and the lower end of the second inclined surface is in front of the upper end of the second section plane. The pushing bent rod 330 has a first section and a second section. The first section of the pushing bent rod 330 extends left and right. The left end of the first section of the pushing bent rod 330 is fixedly connected to the detection plate 210. The second section of the pushing bent rod 330 extends front and back. The rear end of the second section of the pushing bent rod 330 is fixedly connected to the right end of the first section of the pushing bent rod 330. The front end of the second section of the pushing bent rod 330 abuts against the second inclined surface of the fixed block 340. As the thickness of the cable wound on the winding wheel 120 gradually increases, the detection plate 210 squeezes the first spring, and the second section of the pushing bent rod 330 squeezes the fixed block 340, so that the adjustment plate 310 slides forward to slow down the speed of the motor 170 driving the winding wheel 120 to rotate.

[0026] The pressing component includes a slider 410, a pressing rod 420 and an adjusting unit. A slide rail 118 is fixedly arranged on the second bracket 114. The slide rail 118 extends forward and backward and is on the same horizontal plane as the first axis. The slider 410 is slidably arranged along the slide rail 118. On the upper end surface of the slider 410, there is a first slideway 411 with an upward opening and a limiting groove 412. The first slideway 411 extends in the left-right direction. The limiting groove 412 is parallel to and spaced from the first slideway 411. The slider 410 is slidably arranged along the slide rail 118, and when the slider 410 slides along the slide rail 118, it has a constant resistance. The pressing rod 420 is horizontally arranged and extends left and right. The left end of the pressing rod 420 is slidably arranged along the first slideway 411. A convex block 421 is fixedly arranged on the left side of the lower end of the pressing rod 420. The convex block 421 can slide along the limiting groove 412. A second elastic member is fixedly connected between the left end of the pressing rod 420 and the right end of the first slideway 411. Specifically, the second elastic member is a second spring, and the second spring is in a stretched state, so that the pressing rod 420 always has a tendency to slide to the right. A plurality of limiting blocks 413 are arranged in the limiting groove 412. Each limiting block 413 is in the structure of a right triangular prism, and each limiting block 413 can slide in the depth direction of the limiting groove 412. A third spring is arranged between the lower end of each limiting block 413 and the inner end of the limiting groove 412. The limiting block 413 hinders the convex block 421 from sliding to the right along the limiting groove 412, so that the right end of the pressing rod 420 has a fixed distance from the cable winding wheel 120 or the cable wound around the cable winding wheel 120. During the process of the cable gradually winding around the cable winding wheel 120, the cable gradually advances along the first axis direction of the cable winding wheel 120, so that the side wall of the right end of the pressing rod 420 abuts against the side wall of the cable in the advancing direction along the first axis direction. The cable pushes the pressing rod 420 to move synchronously along the first axis direction, driving the slider 410 to slide along the slide rail 118. The slider 410 has a constant resistance when sliding along the slide rail 118. The pressing rod 420 hinders the cable from moving along the first axis direction, so that the cable is closely arranged around the cable winding wheel 120.

[0027] The adjusting unit is used to make the pressing rod 420 slide along the first slideway 411 by a distance equal to the diameter of the cable when the cable is wound around the end of the winding wheel 120. Specifically, the adjusting unit includes an adjusting baffle 510 and an adjusting rod 520. There are two adjusting baffles 510, which are fixedly arranged at both ends of the slide rail 118, and the adjusting baffle 510 is fixedly connected to the second bracket 114. Adjusting grooves 511 are arranged on the two side walls of the two adjusting baffles 510 that are close to each other. The opening directions of the two adjusting grooves 511 are opposite to each other, and a plurality of guiding blocks 512 are arranged in each adjusting groove 511. Each guiding block 512 has a right triangular prism structure, so that the guiding block 512 has a first inclined surface. The length of the right-angled side of the guiding block 512 is the same as the diameter length of the cable. The plurality of guiding blocks 512 are arranged at intervals along the adjusting groove 511. In the same vertically extending vertical plane, one end of the vertical plane is on the first inclined surface of the guiding block 512 in one of the adjusting grooves 511, and the other end of the vertical plane is between two guiding blocks 512 in one of the adjusting grooves 511, so that the guiding blocks 512 in the two adjusting grooves 511 are staggered. The adjusting rod 520 is horizontally arranged and is parallel to the slide rail 118. The middle of the adjusting rod 520 is fixedly arranged at the left end of the pressing rod 420, and the distances from both ends of the adjusting rod 520 to the pressing rod 420 are the same. When the cable is wound around the end of the winding wheel 120, the advancing direction of the cable wound on the winding wheel 120 is changed, and the thickness of the cable wound on the winding wheel 120 increases. The cable gradually pushes the pressing rod 420 to move along the first axis direction, so that the end of the adjusting rod 520 gradually abuts against the first inclined surface of the guiding block 512. As the cable continues to push the pressing rod 420 to move along the first axis direction, the adjusting rod 520 slides along the first inclined surface, driving the pressing rod 420 to slide along the first slideway 411 by a distance equal to the width of one guiding block 512. At this time, the pressing rod 420 no longer abuts against the cable. After the thickness of the cable wound around the winding wheel 120 increases, the pressing rod 420 abuts against the side wall of the cable advancing along the first axis again.

[0028] In this embodiment, a damping rod 610 is fixedly arranged on the first support 113. The axis of the damping rod 610 is arranged parallel to the first axis. The damping rod 610 has a damping cavity with a hollow interior, and the length of the damping cavity is the same as the length of the winding wheel 120. There is damping liquid in the damping cavity. Two damping rings 611 are coaxially arranged in the damping cavity. The circumferential side wall of the damping ring 611 abuts against the side wall of the damping cavity, and the two damping rings 611 can slide synchronously along the damping cavity. First notches 612 are arranged on both damping rings 611, so that there are flow channels for the damping liquid on both sides of the two damping rings 611. The two damping rings 611 are rotatably connected. When one damping ring 611 rotates relative to the other damping ring 611, the flow channels of the damping liquid on both sides of the two damping rings 611 are changed. Specifically, when one damping ring 611 rotates clockwise or counterclockwise, the other damping ring 611 rotates counterclockwise or clockwise. A transmission assembly is arranged between the pressing rod 420 and the damping ring 611. When the pressing rod 420 slides along the first slideway 411, the advancing speed of the cable along the first axis direction of the winding wheel 120 decreases. Then the sliding speed of the two rotating rings in the damping cavity slows down, and the two damping rings 611 rotate synchronously in opposite directions, reducing the flow channels of the damping liquid on both sides of the two damping rings 611, so that the resistance of the two damping rings 611 sliding inside the damping cavity remains unchanged.

[0029] In this embodiment, the transmission assembly includes a transmission rod 710 and a driving rod 720. The driving rod 720 includes a third section and a fourth section. The third section is horizontally arranged and extends left and right. The third section is on the same straight line as the pressing rod 420, and the right end of the third section is fixedly connected to the left end of the pressing rod 420. A guiding rod 730 is fixedly arranged on the slider 410. The guiding rod 730 is horizontally arranged and extends left and right. The fourth section of the driving rod 720 is vertically arranged, and the upper end of the fourth section is fixedly connected to the left end of the third section, and the fourth section is slidably connected to the guiding rod 730. Two second slideways 740 that penetrate through from front to back are arranged on the fourth section. Both second slideways 740 extend in the left-right direction. Both second slideways 740 are inclined, and the inclination directions of the two second slideways 740 are opposite, so that the distance between the left ends of the two second slideways 740 is smaller than the distance between the right ends. There are two transmission rods 710. Each transmission rod 710 is U-shaped. Each transmission rod 710 is divided into two long rods and one short rod. One ends of the two long rods are fixedly connected through the short rod. One end of one long rod is slidably arranged in the second slideway 740, and the other end of the long rod is fixedly connected to the damping ring 611. When the pressing rod 420 slides leftward along the first slideway 411, the two transmission rods 710 slide along the second slideways 740 respectively, so that the two damping rings 611 rotate simultaneously and in opposite directions, reducing the flow channel area of the damping liquid on both sides of the two damping rings 611.

[0030] Combined with the above embodiments, the working principle and process of the present invention are as follows: During operation, by detecting the thickness of the cable wound on the take-up wheel 120, the rotation speed of the take-up wheel 120 is adjusted in a timely manner to keep the length of the cable wound on the take-up wheel 120 per unit time stable. Under the combined action of the pressing rod 420 and the detection plate 210, the cables are closely arranged on the take-up wheel 120.

[0031] The detection plate 210 is arranged directly above the take-up wheel 120. There is a telescopic rod 220 fixedly connected between the upper end of the detection plate 210 and the support plate 112, and a first spring is arranged inside the telescopic rod 220. When the first spring is in its original length, the distance between the detection plate 210 and the take-up wheel 120 is less than the diameter of the cable. When winding the cable, the cable is passed through the space between the take-up wheel 120 and the detection plate 210, and the end of the cable is arranged in the locking hole. At this time, the motor 170 is started, and the power output shaft of the motor drives the second transmission wheel 150 to rotate. The second transmission wheel 150 is connected to the first transmission wheel 140 fixedly arranged on the rotating shaft of the take-up wheel 120 through a transmission belt 180. When the motor 170 rotates, the take-up wheel 120 rotates to wind the cable.

[0032] There is a fixed distance between the right end of the pressing rod 420 and the side wall of the take-up wheel 120, and the distance is less than the radius of the pressing rod 420. As the take-up wheel 120 rotates, the cable is wound on the take-up wheel 120. The cable is squeezed by the detection plate 210, so that the cable is wound on the take-up wheel 120 in a single layer. When the cable winds around the take-up wheel 120 for one week, the side wall of the cable abuts against the pressing rod 420. When the cable advances along the first axis direction, the cable pushes the pressing rod 420 to advance synchronously along the first axis direction. The pressing rod 420 drives the slider 410 to slide along the slide rail 118. The damping rod 610 is fixedly arranged on the left side of the slide rail 118. The damping rod 610 has a damping cavity inside. Two damping rings 611 are slidably arranged in the damping cavity. The two damping rings 611 are rotatably connected. When the damping rings 611 slide in the damping cavity, the resistance received by the damping rings 611 depends on the sliding speed of the damping rings 611 and the size of the flow channels of the damping liquid on both sides of the damping rings 611. The driving rod 720 is fixedly arranged at the left end of the slider 410. The damping rings 611 are connected to the driving rod 720 through the transmission rod 710. When the slider 410 slides along the slide rail 118, the driving rod 720 drives the two damping rings 611 to slide in the damping cavity through the transmission rod 710, so that the slider 410 receives a certain resistance when sliding along the slide rail 118, and further makes the cables closely arranged in the first axis direction of the take-up wheel 120.

[0033] When the cable is wound to the end of the take-up wheel 120, the cable needs to change its advancing direction along the first axis. During the process of the cable advancing along the first axis, the adjusting rod 520 fixedly arranged on the pressing rod 420 first abuts against the first inclined surface of the guiding block 512. As the cable continues to push the pressing rod 420, the pressing rod 420 slides leftward along the first slideway 411 by a distance equal to the diameter of the cable. At the same time, the convex block 421 arranged on the left side of the lower end of the pressing rod 420 squeezes a limiting block 413 to move inside the limiting groove 412, stretching the second spring between the pressing rod 420 and the right end of the first slideway 411. The limiting block 413 in the limiting groove 412 restricts the rightward sliding of the pressing rod 420, so that there is a fixed distance between the right end of the pressing rod 420 and the outer sidewall of the cable.

[0034] The pressing rod 420 drives the driving rod 720 to move leftward synchronously. The two second slideways 740 arranged on the fourth section of the driving rod 720 have opposite inclined directions. When the driving rod 720 moves leftward, the end of one long rod of each transmission rod 710 slides along the second slideway 740, and the damping ring 611 fixedly connected to the end of the other long rod rotates, and the rotation directions of the two damping rings 611 are opposite, so that the first notches 612 arranged on the two damping rings 611 are gradually blocked, and the areas of the flow channels of the damping liquid on both sides of the two damping rings 611 are reduced.

[0035] As the cable changes its winding direction on the take-up wheel 120, the winding thickness of the cable on the take-up wheel 120 increases. The detection plate 210 is pushed by the cable to move radially outward of the take-up wheel 120. The detection plate 210 drives the pushing bent rod 330 to move upward synchronously. The second section of the pushing bent rod 330 squeezes and pushes the second inclined surface of the fixed block 340, so that the adjusting plate 310 fixedly connected to the fixed block 340 moves forward along the third slideway 117. The switching plate 320 is fixedly connected to the middle of the adjusting plate 310. The switching groove 321 is arranged on the switching plate 320, and the middle of the transmission belt 180 passes through the switching groove 321. Driven by the adjusting plate 310, the switching plate 320 changes the meshing positions of the transmission belt 180, the first transmission wheel 140 and the second transmission wheel 150, changes the transmission ratio between the second transmission wheel 150 and the first transmission wheel 140, and reduces the rotation speed of the take-up wheel 120. Since the areas of the flow channels of the damping liquid on both sides of the two damping rings 611 are reduced, the resistance suffered by the sliding of the damping rings 611 in the damping cavity remains unchanged all the time, further making the horizontal tightness of the cable wound on the take-up wheel 120 consistent.

[0036] When the cable finishes winding on the take-up wheel 120, the take-up wheel 120 is removed from the third fixing bracket and replaced.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
