Abstract
Description
Technical Field
[0001] This application relates to the field of cable pay-off equipment, and particularly to a horizontal double-wheel dancer for cable pay-off. Background Art
[0002] During the process of cable production, a dancer is required to control the stability during the cable pay-off process.
[0003] The existing pendulum-type dancer mainly consists of a guide wheel, a transmission main shaft, a counterweight, an eccentric wheel, a sensor, a guide wheel pendulum, etc. During use, the main machine drives the cable forward. The cable passes around the guide wheel, and the guide wheel is connected to the guide wheel pendulum. A counterweight is installed at the rear end of the pendulum, and the center of the pendulum is connected to the eccentric wheel through a shaft. The displacement sensor controls the pay-off speed by detecting the distance change. After the pay-off speed is fast, the cable will become loose, the pendulum will drop, and then the sensor will detect it and slow down the pay-off speed, and the pendulum will rise accordingly.
[0004] However, since the tension is not in a stable state all the time, the pendulum will swing up and down significantly, with poor stability, resulting in a thick-leg phenomenon during cable extrusion, causing quality problems. It is only applicable to large wire gauges with slow speeds and has a poor control effect on small wire gauges with uneven speeds. Summary of the Utility Model
[0005] In order to improve the problem of poor cable tension control effect during the pay-off process, this application provides a horizontal double-wheel dancer for cable pay-off.
[0006] This application provides a horizontal double-wheel dancer for cable pay-off, adopting the following technical solutions:
[0007] The horizontal double-wheel dancer for cable pay-off includes a frame body, a fixed guide wheel mechanism, a movable guide wheel mechanism, and a control mechanism. The frame body is arranged in a horizontal state. The fixed guide wheel mechanism is fixedly arranged at one end of the frame body, and the movable guide wheel mechanism is movably arranged at the other end of the frame body. The control mechanism is arranged in the middle of the frame body and between the fixed guide wheel mechanism and the movable guide wheel mechanism. The control mechanism is used to control the movable guide wheel mechanism to slide horizontally on the frame body and control the pay-off speed of the cable.
[0008] By adopting the above technical solutions, the cable is wound around the fixed guide wheel mechanism and the movable guide wheel mechanism. At this time, the tension of the cable will form a reverse pressing effect on the movable guide wheel mechanism. When the pay-off speed is too fast, the cable becomes loose, and the movable guide wheel mechanism will move in the direction where the cable becomes loose under the control of the control mechanism to realize the re-tensioning of the cable. On the contrary, when the cable becomes tight, the movable guide wheel mechanism will move in the direction away from the cable tensioning, so that the tension of the cable can always be maintained in a constant state, thereby quickly and accurately controlling the tension of the cable.
[0009] Optionally, the fixed guide wheel mechanism includes a fixed wheel, a fixed shaft, and a first retaining ring. The fixed shaft is fixedly connected to the front surface of the frame body. A plurality of the fixed wheels are rotatably connected to the fixed shaft through first bearings. The plurality of fixed wheels are arranged at intervals along the length direction of the fixed shaft. The adjacent two fixed wheels are limited by the first retaining ring. The fixed wheel can rotate around the axis of the fixed shaft.
[0010] By adopting the above technical solution, multiple fixed wheels can realize the simultaneous winding of multiple cables. With the cooperation of the first retaining ring and the first bearing, the fixed wheel can rotate reliably on the fixed shaft, thereby ensuring that the cable can be wound stably on the fixed wheel.
[0011] Optionally, the movable guide wheel mechanism includes a movable wheel, a movable shaft, and a second retaining ring. A slide rail and a mounting plate are provided on the front surface of the frame body. The slide rail extends along the length direction of the frame body. A slider is adaptively provided on the slide rail. The mounting plate is connected to the slider. The movable shaft is fixedly arranged on the mounting plate. A plurality of the movable wheels are rotatably connected to the movable shaft through second bearings. The plurality of movable wheels are arranged at intervals along the length direction of the movable shaft. The adjacent two movable wheels are limited by the second retaining ring. The movable wheel can rotate around the axis of the movable shaft.
[0012] By adopting the above technical solution, the number of movable wheels is the same as that of fixed wheels. And with the cooperation of the second retaining ring and the second bearing, it is ensured that each cable can be reliably wound between the corresponding movable wheel and fixed wheel. The mounting plate is used to install and fix the movable shaft, and the mounting plate is connected to the slider. In this way, when the slider moves on the slide rail, the movable shaft and the movable wheel can move in the length direction of the frame body, thereby reliably adjusting the tension of the cable.
[0013] Optionally, a displacement plate is provided on the back surface of the frame body. The displacement plate is connected to the slider through a connecting plate. The displacement plate and the connecting plate are arranged in an L shape. The connecting plate is located below the frame body and is connected to the bottom of the slider.
[0014] By adopting the above technical solution, the connecting plate connects the slider and the displacement plate, enabling the displacement plate to move synchronously with the movable shaft. And the setting of the displacement plate can balance the movable shaft, making the movement of the movable shaft more stable.
[0015] Optionally, the control mechanism includes a cylinder and a sensing unit, the cylinder is arranged on the front side of the frame, and the push rod of the cylinder extends along the length direction of the frame and pushes and pulls the slider; the sensing unit includes a displacement sensor and a mounting bracket, the mounting bracket is arranged on the back side of the frame and is used to install the displacement sensor, the displacement sensor is used to collect motion data of the displacement plate and transmit it to the controller, and the controller is used to control the pay-off speed of the cable.
[0016] By adopting the above technical solution, when the tension changes, the cable will compress the push rod of the cylinder to retract or promote the push rod of the cylinder to extend, thus ensuring that the push rod of the cylinder can automatically displace. After the push rod of the cylinder is displaced, the displacement plate will also displace at the same time and move within the monitoring range of the displacement sensor. At this time, the displacement sensor will collect the movement data of the displacement plate, thereby reliably controlling the pay-off speed of the cable, thereby controlling the tension of the cable more accurately and quickly.
[0017] Optionally, a two-piece joint and a pressure regulating valve are further provided on the back of the frame, and the gas output from the gas source is delivered to the cylinder after passing through the two-piece joint and the pressure reducing valve.
[0018] By adopting the above technical solution, with the cooperation of the two-piece and the pressure regulating valve, the gas delivered to the cylinder by the gas source can be adjusted and the lubrication of the cylinder push rod can be achieved, ensuring that the cylinder push rod can be reliably extended and retracted without getting stuck.
[0019] Optionally, the radial cross-section of the slide rail is convex, and the radial cross-section of the slider is concave, the inner wall of the slider is matched with the outer wall of the slide rail, a through hole is provided in the middle of the slider, and a lubrication mechanism is provided in the through hole; the lubrication mechanism includes a mounting seat and a graphite column, the mounting seat slides adaptably in the through hole, a groove is provided on the side of the mounting seat facing the slide rail, one end of the graphite column is adaptably provided in the groove, and the other end of the graphite column is fitted with the outer wall of the slide rail.
[0020] By adopting the above technical solution, when the slider is sliding, friction will be generated between the graphite column and the slide rail, thereby forming a graphite layer on the slide rail to play a lubricating role and ensure that the slider can slide reliably on the slide rail.
[0021] Optionally, a spring, a spacer and a driving block are further provided in the through hole, one end of the spring is connected to the mounting seat, the other end of the spring is connected to the spacer, the spacer is fitted with the driving block, the driving block is connected to the through hole by a thread, and a hexagonal hole is provided on the side of the driving block away from the spacer.
[0022] By adopting the above technical solution, after rotating the driving block, the driving block will exert a squeezing effect on the spring, thereby ensuring that the graphite column can have sufficient pressure to contact the slide rail, thus improving the continuity of the lubricating effect.
[0023] In summary, the present application includes the following beneficial effects:
[0024] 1. During the wire pay-off process, the change in the wire tension will cause a corresponding change in the force exerted by the wire on the push rod of the air cylinder. Thus, the displacement plate triggers the displacement sensor through the passive expansion and contraction of the push rod of the air cylinder, and then the controller adjusts the wire pay-off speed, so that the wire tension can be controlled reliably and quickly.
[0025] 2. The lubricating effect between the slide rail and the slider is achieved through the friction between the graphite column and the slide rail, thereby ensuring that the slider can slide reliably on the slide rail, and further ensuring that the expansion and contraction accuracy of the push rod of the air cylinder is higher, improving the control effect of the wire tension.

[0032] The following will further describe the present application in detail with reference to the attached Figures 1-5 drawings.
[0033] Figure 1 is a schematic perspective view of the present application,Figure 2 is the main view of this application. Figure 1 and Figure 2 The invention discloses a line-releasing horizontal double-wheel dancing device, comprising a frame 1, a fixed guide wheel mechanism 2, a movable guide wheel mechanism 3 and a control mechanism 4. The frame 1 is arranged in a horizontal state, the fixed guide wheel mechanism 2 is fixed at one end of the frame 1, and the movable guide wheel mechanism 3 is movably arranged at the other end of the frame 1, and the cables are wound between the fixed guide wheel mechanism 2 and the movable guide wheel mechanism 3 in sequence.
[0034] Figure 3 yes Figure 2 The left view of Figure 4 yes Figure 2 See also Figure 3 and Figure 4 Combined with Figure 1 The fixed guide wheel mechanism 2 includes a fixed wheel 21, a fixed shaft 22 and a first retaining ring 23. One end of the fixed shaft 22 is fixedly arranged at the front end of the frame 1, and the other end of the fixed shaft 22 is suspended. A plurality of fixed wheels 21 are sleeved on the other end of the fixed shaft 22. A plurality of fixed wheels 21 are spaced apart on the fixed shaft 22. The first retaining ring 23 is used to limit the position of two adjacent fixed wheels 21 to ensure that the fixed wheel 21 will not slip in the axial direction of the fixed shaft 22. Moreover, a first bearing 24 is provided between the fixed wheel 21 and the fixed shaft 22. Under the support of the first bearing 24, the fixed wheel 21 can reliably rotate around the axis of the fixed shaft 22.
[0035] See also Figure 1 and Figure 4 The movable guide wheel mechanism 3 includes a movable wheel 31, a movable shaft 32 and a second retaining ring 33. A slide rail 5 and a mounting plate 320 are provided at the other end of the front of the frame 1. The slide rail 5 extends along the length direction of the frame 1. A slider 6 is adapted to be provided on the slide rail 5. The slider 6 can slide on the slide rail 5 and will not fall off the slide rail 5. The mounting plate 320 is connected to the slider 6, and one end of the movable shaft 32 is fixedly connected to the mounting plate 320. The other end of the movable shaft 32 is suspended. A plurality of movable wheels 31 are sleeved on the other end of the movable shaft 32. A plurality of movable wheels 31 are spaced apart on the movable shaft 32. The second retaining ring 33 is used to limit the position of two adjacent movable wheels 31, so as to ensure that the movable wheel 31 will not slip in the axial direction of the movable shaft 32. Moreover, a second bearing 34 is provided between the movable wheel 31 and the movable shaft 32. Under the support of the second bearing 34, the movable wheel 31 can reliably rotate around the axis of the movable shaft 32. The same cable is wound around the fixed wheel 21 and the movable wheel 31 in the same plane and is in a tensioned state.
[0036] See also Figure 1 and Figure 4, the control mechanism 4 is arranged in the middle of the frame body 1 and between the fixed guide wheel mechanism 2 and the movable guide wheel mechanism 3. The control mechanism 4 is used to control the movable guide wheel mechanism 3 to slide horizontally on the frame body 1. Specifically, the control mechanism 4 includes a cylinder 41 and a gas source. The push rod of the cylinder 41 extends along the length direction of the frame body 1, and the pushing and pulling effects of the cylinder 41 on the slider 6 can be realized by supplying and exhausting gas to the cylinder 41 through the gas source, so that the slider 6 can slide reliably on the slide rail 5. When the gas source supplies or exhausts gas to the cylinder body of the cylinder 41 through the air pipe, it will also pass through the double union 13 and the pressure regulating valve 14 in sequence. The double union 13 can filter the gas, so that the gas delivered to the cylinder 41 is clean and can play a lubricating role for the push rod of the cylinder 41.
[0037] See Figure 3 and Figure 4 , a displacement plate 11 is arranged on the back of the frame body 1. The displacement plate 11 is connected to the slider 6 through a connecting plate 12. The connecting plate 12 is located below the frame body 1 and connected to the bottom of the slider 6. The displacement plate 11 and the connecting plate 12 are in an L shape after being connected. In this way, when the cylinder 41 pushes the slider 6 to slide on the guide rail, the connecting plate 12 and the displacement plate 11 can also move synchronously. The control mechanism 4 further includes an induction unit. The induction unit includes a displacement sensor 42 and a mounting bracket 43. The mounting bracket 43 is arranged on the back of the frame body 1 and used to mount the displacement sensor 42. That is to say, the displacement sensor 42 is also arranged on the back of the frame body 1 and above the displacement plate 11, and the displacement sensor 42 is used to collect the motion data of the displacement plate 11 and transmit it to the controller, and the controller is used to control the wire release speed.
[0038] The working principle of this embodiment is as follows: When the dancer is not running, the cable is wound around the fixed wheel 21 and the movable wheel 31 and kept in a tensioned state. In this way, the cable will exert a force on the push rod of the cylinder 41 in the opposite direction to the cable transmission direction. When the dancer starts to run, as the wire release speed gradually increases, the cable will become loose, so that the force applied to the push rod of the cylinder 41 becomes smaller. Under the action of the original air pressure in the cylinder body of the cylinder 41, the push rod of the cylinder 41 will extend outwards. That is to say, the loosening of the cable will cause the push rod of the cylinder 41 to be pushed out passively. During this process, the slider 6 will slide on the slide rail 5, and the displacement plate 11 will also slide accordingly. In this way, the displacement sensor 42 will collect the motion data of the displacement plate 11, and then transmit the motion data to the controller. The controller will control the wire release speed and ensure that the cable can be in a tensioned state by reducing the wire release speed.
[0039] When the wire pay-off speed is adjusted to an overly slow state, the wire cable will become tight, and the acting force applied to the push rod of the air cylinder 41 will increase, thereby causing the push rod of the air cylinder 41 to passively contract inward. At this time, the slider 6 and the displacement plate 11 will generate displacements in the opposite direction to when the wire cable becomes loose, and further cause the controller to ensure that the wire cable can be in a tensioned state by increasing the wire pay-off speed. By sensing the displacement direction and displacement speed of the displacement plate 11 through the sensing unit, the wire pay-off speed of the wire cable can be adjusted in a timely and rapid manner to ensure that the wire cable can maintain a tensioned state and the tension force will not be too large.
[0040] Figure 5 is an internal structural sectional view of the slider and the slide rail. Refer to Figure 5 and in combination with Figure 4 , the slide rail 5 is arranged on the front surface of the frame body 1. The radial cross-section of the slide rail 5 is convex-shaped, and the radial cross-section of the slider 6 is concave-shaped. The inner wall of the slider 6 is adapted to the outer wall of the slide rail 5. A through hole 61 is provided in the middle of the slider 6, and a lubrication mechanism is arranged in the through hole 61. The lubrication mechanism includes a graphite column 63, a mounting seat 62, a spring 64, a spacer 65, and a driving block 66 arranged in sequence. One end of the mounting seat 62 is provided with a clamping groove 620, one end of the graphite column 63 is adaptively arranged in the clamping groove 620, the other end of the graphite column 63 is in contact with the outer wall of the slide rail 5, the other end of the mounting seat 62 is connected to one end of the spring 64, the other end of the spring 64 is connected to one side of the spacer 65, the other side of the spacer 65 is in contact with one side of the driving block 66, and an internal hexagonal hole 660 is provided on the other side of the driving block 66, and the driving block 66 is connected to the through hole 61 by threads.
[0041] Before the dancer starts to work, insert an internal hexagonal wrench into the internal hexagonal hole 660, so as to realize the rotation of the driving block 66 through the internal hexagonal wrench, and further enable the driving block 66 to move axially in the through hole 61. During the movement of the driving block 66, the driving block 66 will push the spacer 65 to move towards the direction close to the mounting seat 62, so that the spring 64 is compressed. In this way, the elastic force of the spring 64 can maintain the pushing effect on the graphite column 63 to ensure that the graphite column 63 can always be in contact with the outer wall of the slide rail 5. When the dancer starts to work and the slider 6 slides on the slide rail 5, friction will occur between the graphite column 63 and the slide rail 5, thereby continuously forming a graphite layer on the surface of the slide rail 5, effectively reducing the friction force of the slider 6 moving on the slide rail 5, and improving the smoothness of the sliding process of the slider 6.
[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
