Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a cable insulation core wire wrapping device. Background Art

[0002] Cables are devices used to transmit electrical energy or electrical signals. During the cable production process, an insulating layer needs to be wrapped around the outside of the core wire to avoid interference between the electrical energy and electrical signals between multiple core wires. This is mainly achieved by rotating the wrapping wheel on the core wire wrapping equipment around the core wire, thereby fitting and fixing the insulating layer to the outer ring of the core wire.

[0003] A PTFE microporous cable wrapping tape winding device with application number 202321948589.9 includes a support base, a drive motor, a driving gear, a driven gear ring, a clamping ring, an upper winding support platform, a limit platform, a lower winding support platform, a PTFE microporous cable, a clamping spring, a tightening knob, a cutting blade, a wrapping tape roll, and a winding positioning roller. The bottom of the support base has support legs and a winding avoidance groove, and the support legs are distributed on both sides of the winding avoidance groove. The top of the support base has a gear ring positioning platform and a clamping ring positioning platform. The clamping ring positioning platform is distributed in the front of the winding avoidance groove, and the gear ring positioning platform is distributed in the rear of the winding avoidance groove. The rear of the support base has a motor support platform, and the upper part of the motor support platform is fixedly connected to the drive motor. The front drive shaft of the drive motor is fixedly connected to the driving gear, and the driven gear ring is adapted to the gear ring positioning platform.

[0004] This technical solution compresses the insulating layer through elastic material. Since the compressing springs apply pressure to the insulating layer, the friction between the compressing springs and the insulating layer is increased, which can easily cause the compressing springs and the insulating layer to be worn. Moreover, when another roll of cable needs to be clamped after the production of this roll of cable is completed, the staff has to bend multiple compressing springs to place the core wire between the multiple compressing springs. Otherwise, the elasticity of the multiple compressing springs themselves will reduce the gap between the three, making it impossible for the core wire to pass through, making it inconvenient to insert the core wire. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a cable insulation core wire winding device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable insulation core wire wrapping device, comprising a base, a fixing frame and a bracket fixed on the top of the base, a swing frame connected to the inside of the fixing frame through a torsion spring shaft, and a pressure wheel connected to the inside of the swing frame, a control ring sleeved on the outside of the fixing frame, and a cable connected between the control ring and the swing frame.

[0007] By adopting the above technical solution, pressure is applied to the swing frame axially through the torsion spring to make the swing frame continuously move toward the core wire direction, so that the pressure wheel always presses the insulation layer, so that the core wire body is evenly stressed during the wrapping process, thereby improving the wrapping effect. At the same time, the pressure wheel can be rotated under force, thereby avoiding wear between the pressure wheel and the insulation layer; when the core wire body needs to be inserted, the control ring can be rotated through the handle on the top of the control ring. After the control ring is rotated, the cable is pulled to make multiple swing frames move away from the core wire body at the same time, thereby making multiple pressure wheels move away from the core wire body, which makes it convenient to pass the core wire body through the fixed frame.

[0008] Furthermore, the swing frame is rotatably connected to the fixed frame via a torsion spring shaft, and the pressure wheel is rotatably connected to the swing frame.

[0009] By adopting the above technical solution, the axial pressure of the torsion spring is applied to the swing frame to allow the swing frame to continuously move toward the core wire, and at the same time the pressure wheel can be rotated under force, thereby avoiding wear between the pressure wheel and the insulation layer.

[0010] Furthermore, a handle is fixed on the top of the control ring, and the control ring is rotatably connected to the fixing frame.

[0011] By adopting the above technical solution, the control ring is rotated by the handle on the top of the control ring. After the control ring is rotated, the rope is pulled to make multiple swing frames move away from the core wire body at the same time, thereby making multiple pressure wheels move away from the core wire body. At this time, it is convenient for the staff to pass the core wire body through the fixed frame.

[0012] Furthermore, the pull cables, torsion spring shafts, swing frames and pressure wheels are provided in plurality, and the plurality of pull cables, torsion spring shafts, swing frames and pressure wheels are distributed in a ring array.

[0013] By adopting the above technical solution and increasing the number of pressing wheels, the contact area between the pressing wheels and the insulation layer and the core wire body is increased, thereby improving the pressing effect.

[0014] Furthermore, the cable is a steel wire rope.

[0015] By adopting the above technical solution and using steel wire rope as the pull rope, the structure has high strength and long service life, and can well transmit power to rotate the control ring to rotate the swing frame.

[0016] Furthermore, the top of the bracket is connected to a top frame, and a half gear ring is connected to one side of the bracket and the top frame. A mounting seat is fixed to one side of the half gear ring, and a limiting bolt passes through the top of the mounting seat. A wrapping wheel is sleeved on the outside of the mounting seat. A motor is installed on the other side of the bracket, and a gear is connected to the output end of the motor.

[0017] By adopting the above technical solution, the staff turns on the motor. After the motor starts, the output end drives the gear to rotate. The gear engages with the two half gear rings in turn to rotate the two half gear rings, thereby causing the mounting seat, the limit bolt and the wrapping wheel to revolve, and the subsequent winding equipment begins to rewind the core wire body so that the core wire body begins to move on the wrapping equipment. The wrapping wheel revolves in coordination with the displacement of the core wire body, so that the insulation layer is wrapped around the core wire body to complete the wrapping.

[0018] Furthermore, the wrapping wheel is detachably connected to the mounting seat, and the limiting bolt abuts against the wrapping wheel.

[0019] By adopting the above technical solution, the staff unscrews the limiting bolt and puts the wrapping wheel with the insulation layer on the mounting seat. Then the staff replaces the limiting bolt and tightens it to limit the wrapping wheel and prevent it from falling off during subsequent revolution.

[0020] Furthermore, wheel frames are fixed on both sides of the top of the base, and four guide wheels are connected to the inside of the two wheel frames respectively, and the core wire body is connected between the four guide wheels.

[0021] By adopting the above technical solution, the core wire body is allowed to pass through the wrapping equipment horizontally through the setting of the guide wheel, thereby preventing the core wire body from sagging, thereby ensuring the winding effect.

[0022] Furthermore, the outer portion of the pressure wheel is sleeved with a sheath, and the sheath is made of silicone material.

[0023] By adopting the above technical solution, the core wire body is buffered by the setting of the sheath, thereby avoiding the phenomenon that the core wire body and the insulation layer are compressed, deformed and sunken due to excessive pressure applied by the torsion spring axial swing frame and the pressure wheel.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. The utility model is provided with a control ring, a cable, a torsion spring shaft, a swing frame and a pressure wheel. The torsion spring shaft applies pressure to the swing frame to make the swing frame continuously move toward the core wire direction, so that the pressure wheel always presses the insulation layer tightly, so that the core wire body is evenly stressed during the wrapping process, improving the wrapping effect. At the same time, the pressure wheel can be rotated under force, thereby avoiding wear between the pressure wheel and the insulation layer; when the core wire body needs to be inserted, the control ring can be rotated by the handle on the top of the control ring. After the control ring is rotated, the cable is pulled to simultaneously move multiple swing frames away from the core wire body, thereby moving multiple pressure wheels away from the core wire body, making it easier to pass the core wire body through the fixed frame; the structure is stable, less worn, and convenient for passing the core wire body;

[0026] 2. The utility model buffers the core wire body through the setting of the sheath, thereby avoiding the phenomenon that the core wire body and the winding distance are compressed, deformed and sunken due to excessive pressure applied by the torsion spring axial swing frame and the pressure wheel; it is convenient to protect and avoid damage to the core wire body and the insulation layer.

Multiple cables 4, torsion spring shafts 5, swing frames 6 and pressure wheels 7 are distributed in a circular array. The staff rotates the control circle 3 through the handle on the top of the control circle 3. After the control circle 3 rotates, the cable 4 is pulled to make multiple swing frames 6 move away from the core wire body 11 at the same time, thereby making multiple pressure wheels 7 move away from the core wire body 11, which makes it convenient for the staff to pass the core wire body 11 through the fixed frame 2.

[0036] See Figure 1 、 Figure 2 and Figure 4 In the above embodiment, the top of the bracket 12 is connected to the top frame 13, and one side of the bracket 12 and the top frame 13 is connected to a half gear ring 16. A mounting seat 17 is fixed to one side of the half gear ring 16. A limiting bolt 18 passes through the top of the mounting seat 17. A wrapping wheel 19 is sleeved on the outside of the mounting seat 17. The wrapping wheel 19 is detachably connected to the mounting seat 17, and the limiting bolt 18 abuts against the wrapping wheel 19. A motor 14 is installed on the other side of the bracket 12, and a gear 15 is connected to the output end of the motor 14. After the motor 14 is started, the output end drives the gear 15 to rotate, and the gear 15 engages with the two half gear rings 16 in turn to make the two half gear rings 16 rotate Rotate, thereby making the mounting seat 17, the limiting bolt 18 and the wrapping wheel 19 revolve, and the subsequent winding device starts to rewind the core wire body 11 so that the core wire body 11 starts to move on the wrapping device, and the wrapping wheel 19 revolves to cooperate with the displacement of the core wire body 11, so that the insulation layer is wrapped on the core wire body 11 to complete the wrapping; wheel frames 9 are fixed on both sides of the top of the base 1, and four guide wheels 10 are respectively connected to the inside of the two wheel frames 9, and the core wire body 11 is connected between the four guide wheels 10. Through the setting of the guide wheels 10, the core wire body 11 is horizontally passed through the wrapping device to avoid the core wire body 11 from sagging, thereby ensuring the winding effect.

[0037] Example 2:

[0038] On the basis of the above-mentioned embodiment 1, in order to prevent the core wire body 11 from being crushed, the following configuration is adopted.

[0039] See Figure 1-Figure 3In the above embodiment, the outer surface of the pressure wheel 7 is covered with a sheath 8, which is made of silicone material. The sheath 8 is provided to buffer the core wire body 11, thereby preventing the torsion spring shaft 5 from applying excessive pressure to the swing frame 6 and the pressure wheel 7, thereby preventing the core wire body 11 from being deformed and sunken due to pressure.

[0040] The working principle of the present invention is as follows: first, the staff unscrews the limiting bolt 18 and puts the wrapping wheel 19 equipped with the insulation layer on the mounting seat 17. Then the staff replaces the limiting bolt 18 and tightens it, thereby limiting the wrapping wheel 19 and preventing it from falling off during subsequent revolutions.

[0041] The staff passes the core wire body 11 through the gap between the guide wheels 10, the fixing frame 2 and the bracket 12, and then the staff fits the insulation layer on the wrapping wheel 19 with the core wire body 11, thus completing the threading work; when the core wire body is passed through the fixing frame 2, the staff rotates the control ring 3 by the handle on the top of the control ring 3. After the control ring 3 rotates, the cable 4 is pulled to simultaneously move the multiple swing frames 6 away from the core wire body 11, thereby moving the multiple pressure wheels 7 away from the core wire body 11, making it easier for the staff to pass the core wire body 11 through the fixing frame 2;

[0042] After the preparation work is completed, the staff turns on the motor 14. After the motor 14 is started, the output end drives the gear 15 to rotate, and the gear 15 engages with the two half gear rings 16 in turn to rotate the two half gear rings 16, thereby causing the mounting seat 17, the limit bolt 18 and the wrapping wheel 19 to revolve, and the subsequent winding device begins to rewind the core wire body 11 so that the core wire body 11 begins to move on the wrapping device. The wrapping wheel 19 revolves to match the displacement of the core wire body 11, so that the insulation layer is wrapped around the core wire body 11 to complete the wrapping. Then, pressure is applied to the swing frame 6 through the torsion spring shaft 5 to make the swing frame 6 continuously move toward the core wire body 11, so that the pressure wheel 7 always presses the insulation layer tightly, so that the insulation layer is evenly stressed during the wrapping process, thereby improving the wrapping effect. At the same time, the pressure wheel 7 can be rotated under force, thereby avoiding wear between the pressure wheel 7 and the insulation layer, and the core wire body 11 is buffered by the setting of the sheath 8, thereby avoiding the phenomenon that the pressure applied by the torsion spring shaft 5 to the swing frame 6 and the pressure wheel 7 is too large, resulting in the core wire body 11 and the insulation layer being compressed, deformed and sunken.
