Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more particularly to a wire drawing device for cable processing. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for controlling installation, connecting equipment, transmitting electricity, and other multiple functions. They are common and indispensable in daily life. Because cables are charged, installation requires special care. Cable paralleling is the process of connecting the same power cores of more than two cables. The application scenarios of cable paralleling include paralleling of multiple cables and paralleling of single-strand hard copper wire cables.

[0003] Different paralleling methods may be required for cables of different materials and specifications. For example, the paralleling methods for copper and aluminum conductors are different because the surface of aluminum core wires is extremely susceptible to oxidation. Directly hinged or crimped connection may cause galvanic corrosion, resulting in increased contact resistance and overheating, which can cause line failures. Therefore, aluminum conductors are usually connected by tight compression and copper or aluminum sleeves are used to maintain the connection. In addition, for paralleling multi-strand cables, the copper core of the multi-strand cable is soft and relatively easy to parallel. The core wires of the multi-strand cable can be twisted and tightened first, then tightly wrapped around the core wire of another conductor, and finally the excess wire ends can be cut off. When paralleling cables, if the tension between the cores is uneven or too large, the cores may break. In the prior art, when a cable breaks during the winding process, the taut wire core quickly rebounds and falls to the ground. Although the cable processing site is cleaned regularly, impurities are inevitable. If the impurities adhere to the surface of the wire core, additional cleaning steps must be completed before winding can continue, which affects the processing efficiency of the cable. Summary of the Invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a wire drawing device for cable processing.

[0005] To solve the above problems, the present invention adopts the following technical solution, which can lock the rebounding wire core in time after the wire core breaks during the wire winding process, effectively preventing the wire core from falling to the ground due to breakage, thereby saving the subsequent step of cleaning impurities on the surface of the wire core.

[0008] Furthermore, a pressing assembly is provided on both the inside and outside of the fixed cylinder, and the pressing assembly includes sliding grooves provided on the front and rear sides of the inner wall of the movable groove.

[0009] Furthermore, the slide groove is slidably connected to a slider, and the slider is fixedly connected to the back side of the connecting bracket.

A first magnetic block is provided on the upper and lower sides of the front end of the clamping ring, and a second magnetic block is provided on the upper and lower sides of the inner surface of the connecting strip.

[0010] Furthermore, the movable groove passes through the left side of the fixed cylinder, the shapes of the first connecting plate and the second connecting plate are adapted to the shape of the movable groove, and the first magnetic block and the second magnetic block are magnetically attracted to each other.

[0011] Furthermore, a warning component is provided on the outside of the body, and the warning component includes a pressure spring fixedly connected to the left side of the slider.

[0012] Furthermore, the other end of the pressure spring is fixedly connected to the inner left side of the slide, a firing pin is fixedly connected to the left side of the slider, a pressure sensor is provided on the inner left side of the slide, the pressure spring is wrapped around the outside of the firing pin and the pressure sensor, and the firing pin is squeezed and contacted with the right side of the pressure sensor after movement, a controller is provided on the front side of the body, and a warning light is provided on the front side of the body.

[0013] Furthermore, an adjusting component is provided on the right side of the driving disk, and the adjusting component includes electric push rods arranged on the front and rear sides of the right end of the driving disk.

[0014] Furthermore, the telescopic end of the electric push rod is fixedly connected to a push plate, and the interior of the push plate is provided with limiting grooves arranged in a circular array.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The rubber sheet provided in the present invention allows the wire core to pass smoothly when it moves to the right, and is locked by the rubber sheet when the wire core rebounds. Since the wire core breaks during the winding process, the rebounding wire core will be locked by multiple rubber strips, effectively preventing the wire core from falling to the ground due to the breakage. This not only facilitates the re-docking of the wire core, but also saves the subsequent step of cleaning impurities on the surface of the wire core, thereby ensuring the winding efficiency of the wire core.

[0017] (2) The present invention uses a clamping ring to press the wire core when the second connecting plate is separated from the movable groove. Since the rubber sheet wraps the wire core, the second connecting plate separated from the movable groove will quickly press the wire core through the clamping ring, which further improves the locking effect of the wire core and again prevents the wire core from falling to the ground due to breakage. After the driving disk stops rotating, the wire core can continue to be pressed by the magnetic adsorption of the first magnetic block and the second magnetic block.

[0018] (3) The present invention provides a striker that contacts the pressure sensor after movement, and then activates the warning light and turns off the drive disk through the controller. Since the wire core is locked after breaking, the warning light will be activated at the same time, which not only serves as a warning to the staff, but also facilitates the timely processing of the wire core after the drive disk stops running, so as to ensure the quality of the wire core after winding, and reduce the frequency of defective cables.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 , a doubling device for cable processing, comprising a body 1 and a drive disc 11 arranged on the right side of the upper end of the body 1, a locking component 2 is provided on the right side of the drive disc 11; The locking component 2 includes a connecting strip 21 arranged in a circular array and hinged on the right side of the driving disk 11. The inner surface of the connecting strip 21 is fixedly connected to a fixed cylinder 22. A movable groove 23 is provided on the inner wall of the fixed cylinder 22. The left and right sides of the movable groove 23 are slidably connected to movable disks 24. The outer sides of the left and right corresponding movable disks 24 are commonly fixedly connected with a connecting bracket 25. The connecting bracket 25 is slidably connected to the inside of the movable groove 23. The right side of the movable disk 24 is fixedly connected with a rubber sheet 26 arranged in a circular array.

[0023] The connecting strip 21 is arranged at an angle, the shape of the movable plate 24 is adapted to the shape of the movable groove 23 , and the rubber sheet 26 is arranged at an angle.

[0024] By adopting the above technical solution, the machine body 1 is equipped with a wire core and the wire core passes through the driving disk 11, and then the wire core is pulled so that the wire core passes through the fixed cylinder 22 fixed by the connecting strip 21. In the process of the wire core passing through the fixed cylinder 22, the wire core passes through multiple gathered rubber sheets 26, so that the rubber sheets 26 are pushed open. When the wire core breaks due to excessive tension during the winding process, the wire core in a taut state rebounds quickly. In this process, because the multiple gathered rubber sheets 26 are always in contact with the outside of the wire core, when the wire core moves to the right, the wire core will stretch the multiple rubber sheets 26 so that the wire core can pass smoothly. When the wire core moves in the opposite direction due to rebound, the force points of the multiple rubber sheets 26 change, so that the multiple rubber sheets 26 begin to gather and fit tightly to the outside of the wire core, making it difficult for the wire core to break. To continue moving, at the same time, multiple rubber sheets 26 are fixed to the side of the same moving disk 24, and the two moving disks 24 are fixed inside the same connecting bracket 25. When the wire core pulls the rubber sheet 26 to the left, the connecting bracket 25 will slide inside the moving groove 23 due to the push from the moving disk 24. When the connecting bracket 25 moves to the side of the moving groove 23, the connecting bracket 25 cannot continue to move, and the wire core locked by the rubber sheet 26 will also not be able to continue to move. After the wire core breaks during the wire winding, the rebounding wire core will be locked by multiple rubber sheets 26, which effectively prevents the wire core from falling to the ground due to breakage. It is not only convenient for re-docking the wire core, but also saves the subsequent steps of cleaning impurities on the surface of the wire core, so that the wire winding efficiency of the wire core is guaranteed.

[0025] like Figures 4 to 8 As shown, a pressing assembly 27 is provided on both the inner and outer sides of the fixing cylinder 22 . The pressing assembly 27 includes sliding grooves 271 provided on the front and rear sides of the inner wall of the movable groove 23 .

[0026] The inside of the slide groove 271 is slidably connected to a slider 272, and the slider 272 is fixedly connected to the back of the connecting bracket 25. A movable groove 273 is provided on the inner back side of the back slide groove 271. The back side of the slider 272 is fixedly connected to a first connecting plate 274, and the first connecting plate 274 is slidably connected to the movable groove 273. The left side of the first connecting plate 274 is hinged with a second connecting plate 275, and the right end of the second connecting plate 275 is slidably connected to the inside of the movable groove 273. The front end left side of the second connecting plate 275 is fixedly connected to a snap ring 276, and the inner surface of the snap ring 276 is fixedly connected to a rubber strip 277 arranged in a horizontal linear array. The upper and lower sides of the front end of the snap ring 276 are provided with first magnetic blocks 278, and the upper and lower sides of the inner surface of the connecting strip 21 are provided with second magnetic blocks 279.

[0027] The movable groove 273 passes through the left side of the fixed cylinder 22 . The shapes of the first connecting plate 274 and the second connecting plate 275 match the shape of the movable groove 273 . The first magnetic block 278 and the second magnetic block 279 are magnetically attracted to each other.

[0028] When the second connecting plate 275 is completely separated from the movable groove 273, the slider 272 can only continue to move a small distance. Because the driving disk 11 is in a rotating state, after the second connecting plate 275 is separated from the movable groove 273, it will move toward the connecting bar due to the rotation of the driving disk 11. 21, as the snap ring 276 on the other side of the second connecting plate 275 contacts the connecting strip 21, after the driving disk 11 stops rotating, the second magnetic block 279 on the side of the snap ring 276 will be magnetically attracted to the first magnetic block 278 on the side of the connecting strip 21. At this time, the snap ring 276 will also press the wire core, and at the same time, the rubber strip 277 inside the snap ring 276 will contact the outside of the wire core, so that the wire core is locked. As the rubber strip 277 wraps the wire core, the second connecting plate 275 detached from the movable groove 273 will quickly press the wire core through the snap ring 276, further improving the locking effect of the wire core, and once again avoiding the wire core from falling to the ground due to breakage. After the driving disk 11 stops rotating, the wire core can continue to be pressed by the magnetic attraction of the first magnetic block 278 and the second magnetic block 279.

[0029] like Figures 6 to 8 As shown, a warning assembly 28 is provided on the outside of the body 1 , and the warning assembly 28 includes a pressure spring 281 fixedly connected to the left side of the slider 272 .

[0030] The other end of the pressure spring 281 is fixedly connected to the inner left side of the slide groove 271, and the left side of the slider 272 is fixedly connected to the striker 282. A pressure sensor 283 is provided on the inner left side of the slide groove 271. The pressure spring 281 is wrapped around the outside of the striker 282 and the pressure sensor 283. After the striker 282 moves, it is squeezed and contacted with the right side of the pressure sensor 283. A controller 284 is provided on the front side of the body 1, and a warning light 285 is provided on the front side of the body 1.

[0031] By adopting the above technical solution, when the slider 272 slides to the left inside the slide groove 271, the slider 272 can drive the striker 282 to move and squeeze the pressure spring 281. When the striker 282 contacts the pressure sensor 283 inside the slide groove 271, the pressure sensor 283 transmits the information to the controller 284. Then, the controller 284 starts the warning light 285 and the controller 284 will also turn off the drive disk 11. Since the wire core is locked after breaking, the warning light 285 will be started, which not only serves as a warning to the staff, but also facilitates the timely processing of the wire core after the drive disk 11 stops running, so as to ensure the quality of the wire core after paralleling and reduce the frequency of defective cables.

[0032] like Figures 2 to 4 As shown, an adjusting component 3 is provided on the right side of the driving disc 11 , and the adjusting component 3 includes an electric push rod 31 provided on the front and rear sides of the right end of the driving disc 11 .

[0033] The telescopic end of the electric push rod 31 is fixedly connected to a push plate 32, and the interior of the push plate 32 is provided with limit slots 33 arranged in a circular array. The interior of the limit slots 33 is rotatably connected to the limit rods 34. The adjacent left and right corresponding limit slots 33 are a group, and the adjacent left and right corresponding limit rods 34 are a group.

[0034] The outer side of the push plate 32 is arranged in a circular array and rotated in contact with a movable ring 35. Each set of limit rods 34 is located on the left and right sides of the movable ring 35 respectively. The movable ring 35 is slidably sleeved on the outer side of the connecting bar 21.

[0035] When the cam 33 is in the unlock state, the cam 33 is unlocked, and the cam 33 is unlocked, so that the cam 33 is unlocked and the cam 33 is unlocked.

[0036] Working principle: When the wire core passes through the fixed cylinder 22, it will pass through multiple gathered rubber sheets 26, so that the rubber sheets 26 are pushed open. When the wire core breaks due to excessive tension during the winding process, the wire core in a taut state rebounds quickly. When the wire core moves to the right, the wire core will stretch out the multiple rubber sheets 26, so that the wire core can pass smoothly. When the wire core moves in the opposite direction due to rebound, the force points of the multiple rubber sheets 26 change, so that the multiple rubber sheets 26 begin to gather and fit tightly to the outside of the wire core, making it difficult for the wire core to continue moving. When the wire core pulls the rubber sheet 26 to the left, the connecting bracket 25 will be pushed by the movable disk 24 and The movable groove 23 slides inside. When the connecting bracket 25 moves to the side of the movable groove 23, the connecting bracket 25 cannot move further, and the wire core locked by the rubber sheet 26 will also be unable to move further. The slider 272 on the back side is fixed with the first connecting plate 274, and the first connecting plate 274 is inside the movable groove 273. When the slider 272 drives the first connecting plate 274 to slide inside the movable groove 273, the second connecting plate 275 hinged to the first connecting plate 274 will gradually move out of the movable groove 273. Because the driving disk 11 is in a rotating state, after the second connecting plate 275 is disengaged from the movable groove 273, it will move toward When the connecting strip 21 moves in the direction of the connecting strip 21, as the snap ring 276 on the other side of the second connecting plate 275 contacts the connecting strip 21, after the driving disk 11 stops rotating, the second magnetic block 279 on the side of the snap ring 276 will be magnetically attracted to the first magnetic block 278 on the side of the connecting strip 21. At this time, the snap ring 276 will also press the wire core. At the same time, the rubber strip 277 inside the snap ring 276 will contact the outside of the wire core, so that the wire core is locked. When the slider 272 slides to the left inside the slide groove 271, the slider 272 can drive the striker 282 to move and squeeze the pressure spring 281. When the striker 282 contacts the pressure sensor 283 inside the slide groove 271, the pressure The force sensor 283 transmits the information to the controller 284, and then the controller 284 activates the warning light 285. At the same time, the controller 284 will also turn off the drive disk 11, and then start the electric push rod 31 to push or pull the push disk 32. Because the movable ring 35 on the outside of the connecting strip 21 is connected to the limiting groove 33 inside the push disk 32 through the limiting rod 34, as the push disk 32 drives the movable ring 35 to move on the outside of the connecting strip 21, the movable ring 35 will push the connecting strip 21, so that the inclination angle of the connecting strip 21 originally hinged on the right side of the drive disk 11 and the right side of the drive disk 11 will change, so that the tension of the wire core will change.

[0037] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
