Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to a cable synchronous traction system. Background Art

[0002] The wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion are mainly made by drawing, twisting and coating. In the coating process of the cable, one end of the wire core needs to be wound on the unwinding roller and the other end on the winding roller. The unwinding roller and the winding roller cooperate to realize the transmission of the wire core. The wire core passes through the inside of the extruder during the transmission to the side of the winding roller. The extruder uses a screw of a specific shape to rotate in a heated barrel to extrude the plastic sent from the hopper forward, so that the plastic is evenly plasticized (i.e. melted). Through the head and molds of different shapes, the plastic is extruded into continuous plastic layers of various shapes required, and then extruded on the wire core. At present, the unwinding and reeling system of the existing technology cable cannot keep the wire core in a tensioned state at all times during use. The bamboo knot phenomenon caused by uneven wire core release during extrusion has a low product qualification rate. In addition, the existing technology cannot quickly cool the cable after extrusion. People are prone to burn their skin when storing the cable, and the operation is unsafe. Summary of the invention

[0012] (III) Beneficial effects

[0013] The present invention provides a cable synchronous traction system, which has the following beneficial effects:

[0014] (1) The present invention is provided with a traction gear, a transmission tooth chain, a transmission mechanism and a driving motor. When in use, the driving motor drives the small pulley in the transmission mechanism to rotate, the small pulley drives the large pulley to rotate through the belt, and the large pulley drives the traction gear at one end of the coaxial wire-retrieving mechanism to rotate.

The blower installed on the top of the cooling box continuously blows external cold air into the cooling box. The cold air is guided by the guide plate and blows toward the cable, taking away the heat on the cable, and is discharged through the heat dissipation holes at the bottom of the cooling box, thereby cooling the cable. This can prevent people from getting skin burns when storing the cable, thereby improving the safety of processing. BRIEF DESCRIPTION OF THE DRAWINGS

The electric telescopic rod 20 can be contracted under the control of the PLC controller 5 to drive the movable plate 14 to slide toward the end away from the fixed plate 13, so as to facilitate the personnel to disassemble and install the line roller 19. The bottom of the movable plate 14 is slidably connected to the slide rail 15 arranged on the bottom plate 12, and the fixed plate 13 and the movable plate 14 are symmetrically provided with shaft sleeves 16. The internal transmission connection of the shaft sleeve 16 is connected with a hollow shaft tube 17. A wire roller 19 is arranged between the two hollow shaft tubes 17. The wheel axles at both ends of the wire roller 19 are inserted into the hollow shaft tubes 17 on both sides. A traction gear 7 is installed at the outer end of the hollow shaft tube 17 installed on the fixed plate 13. A transmission tooth chain 8 is installed between the two traction gears 7 at the outer ends of the wire release mechanism 2 and the wire take-up mechanism 3. The bottom of the frame 1 is located at the wire take-up machine A drive motor 10 is installed directly below the wire take-up mechanism 3, and a transmission mechanism 9 is arranged between the drive motor 10 and the traction gear 7 located at the outer end of the wire take-up mechanism 3. The cooling mechanism 6 includes a cooling box 24, a guide plate 26 and a blower 27. Two guide plates 26 are symmetrically installed inside the cooling box 24, and a blower 27 is installed on the upper end of the guide plate 26. The PLC controller 5 model is S7-200, which is an existing disclosed technology.

[0026] Furthermore, cable holes 25 are provided at both ends of the cooling box 24, and the two cable holes 25 are at the same height and consistent with the transmission direction of the cable. The diameter of the cable hole 25 is twice the diameter of the cable. The purpose of this design is to facilitate the cable to pass through the cable hole 25, and when the cable is tensioned, it will not be damaged by friction with the side wall of the cable hole 25.

[0027] Furthermore, a power storage box 11 is installed at the bottom of the rack 1, and the output end of the power storage box 11 is electrically connected to the input end of the PLC controller 5. The power storage box 11 is used to provide power to the PLC controller 5 and provide power to other electrical equipment through the PLC controller 5.

[0028] Working principle: When in use, the driving motor 10 drives the small pulley 22 in the transmission mechanism 9 to rotate, and the small pulley 22 drives the large pulley 21 to rotate through the belt 23, and the large pulley 21 drives the traction gear 7 at one end of the coaxial take-up mechanism 3 to rotate, and the traction gear 7 drives the traction gear 7 at one end of the pay-off mechanism 2 to rotate synchronously through the transmission tooth chain 8, thereby driving the pay-off mechanism 2 and the take-up mechanism 3 to pay out and take up the wire synchronously, so that the wire core is in a tensioned state when passing through the cable extruder 4. When the wire core is coated with plastic skin in the cable extruder 4, its surface temperature is relatively high. At this time, the cable enters the cooling box 24 through the cable hole 25 opened in the cooling box 24 under the drive of the wire roller 19, and the blower 27 installed on the top of the cooling box 24 continuously blows external cold air into the cooling box 24.

[0029] In summary, the present invention sets a cooling mechanism 6, a traction gear 7, a transmission tooth chain 8, a transmission mechanism 9 and a driving motor 10. The driving motor 10 drives the two traction gears 7 to rotate synchronously through the transmission mechanism 9 and the transmission tooth chain 8, and then drives the wire-releasing mechanism 2 and the wire-retrieving mechanism 3 to be driven synchronously through the two traction gears 7, thereby solving the bamboo knot phenomenon easily caused by uneven wire-releasing and the low product qualification rate in the prior art. The cooling mechanism 6 can cool the cables after extrusion processing, thereby solving the problem that the prior art cannot quickly cool the cables after extrusion, which easily causes burns to people.
