Description

Technical Field

[0001] This utility model relates to the field of wire stripping machine technology, and more specifically, to a wire pulling device for a wire stripping machine. Background Technology

[0002] A wire stripper is a machine that strips the plastic sheath from the metal core of wires. Different models are suitable for different wire diameters, materials, and compositions: computer-controlled wire strippers for short and thin wires, large square wires, ribbon cables, sheathed wires, coaxial cables, etc.

[0003] A search revealed that utility model patent CN212694908U discloses a wire pulling device for an automatic electrical wire stripper, comprising a stripping device body and a discharge port. The discharge port is fixedly installed at the middle position of one side of the outer wall of the stripping device body. Two sets of fixing frames are symmetrically welded to the upper and lower sides of the outer wall of the stripping device body. Each of the two sets of fixing frames has a fixed wheel rotatably mounted inside via a rotating shaft. Multiple sets of support rods are welded to the outside of the two sets of fixed wheels. A pressure plate is welded to the end of each support rod opposite to the fixed wheel. A drive wheel is fixedly installed on the back side of each of the two sets of fixing frames. This wire pulling device for the automatic electrical wire stripper improves the ease of use of the device through the cooperation of the fixed wheels, support rods, pressure plates, drive wheels, belts, and drive motor. Furthermore, the wire pulling device ensures adaptability to different cables through the cooperation of grooves, movable rods, springs, pressure plates, and rubber sheets.

[0004] However, the above patent still has the following shortcomings: although it can pull the stripped cable, it is not convenient to rewind the stripped cable, and its practicality is not good; when the length of the cable to be stripped is short, it is dangerous for the staff to manually extend the cable into the stripping machine. Therefore, we have proposed a cable pulling device for the stripping machine. Utility Model Content

Multiple wire inlets 2 are provided on one side of the wire stripping machine body 1, and multiple wire outlets 3 are provided on the other side. A feeding mechanism 4 is provided on one side of the wire stripping machine body 1, and a mounting frame 5 is fixedly connected to the other side of the wire stripping machine body 1. A second motor 6 is fixedly mounted on the mounting frame 5. A transmission column 7 is fixedly connected to the output shaft of the second motor 6. Two take-up drums 8 are sleeved on the outer side of the transmission column 7. Each of the two take-up drums 8 is provided with a clamping and fixing mechanism 9. Multiple screw holes 10 are provided on the transmission column 7. A fixing seat 11 is fixedly connected to the side of the take-up drum 8. A mounting hole 12 is provided on the fixing seat 11. A wing screw 13 is sleeved on the inner side of the mounting hole 12, and the end of the wing screw 13 is threaded into the inner cavity of the screw hole 10.

[0028] In this embodiment, the inner diameters of the multiple inlet ports 2 and the multiple outlet ports 3 are different, so as to strip cables of different diameters.

[0029] For details, please refer to Figure 1 and Figure 3 The feeding mechanism 4 includes two support frames 14 fixedly connected to one side of the wire stripper body 1. Two conveying cylinders 15 are rotatably connected between the two support frames 14. Sponge cylinders 16 are fixedly sleeved on the outer side of the two conveying cylinders 15 respectively. Two first motors 17 are fixedly installed on the outer side of one support frame 14. The output shafts of the two first motors 17 are respectively connected to one end of the rotating shaft of the two conveying cylinders 15.

[0030] In this embodiment, the height between the two conveying cylinders 15 is matched with the height of the inlet 2.

[0031] For details, please refer to Figure 1 and Figure 5 The clamping and fixing mechanism 9 includes a movable groove 18 opened inside the winding drum 8. A bidirectional lead screw 19 is rotatably connected to the inner cavity of the movable groove 18. Clamping plates 20 are threaded onto the outer sides of both ends of the bidirectional lead screw 19. One end of the bidirectional lead screw 19 extends to the outside of the winding drum 8 and is fixedly connected to a lever block 21.

[0032] In this embodiment, the two clamping plates 20 are brought closer together by the threaded engagement between the bidirectional lead screw 19 and the two clamping plates 20, thereby clamping and fixing the cable, and then winding up the stripped inner core and outer tube.

[0033] For details, please refer to Figure 1 The front of the wire stripper body 1 is hinged with a maintenance door 22, and a control panel 23 is fixedly installed on the maintenance door 22.

[0034] In this embodiment, the control panel 23 is used to control the first motor 17 and the second motor 6, and at the same time, the control panel 23 is used to control the wire stripping mechanism in the wire stripping machine body 1.

[0035] For details, please refer to Figure 2 and Figure 5 The inner diameter of the mounting hole 12 is equal to the outer diameter of the wing screw 13.

[0036] In this embodiment, the stability of the wing screw 13 being fitted into the mounting hole 12 is ensured, thereby ensuring the stability of the winding drum 8 being mounted on the transmission column 7.

[0037] For details, please refer to Figure 5 The side of the clamping plate 20 fits against the inner wall of the moving groove 18.

[0038] In this embodiment, the clamping plate 20 is limited by the inner wall of the moving groove 18, so that the clamping plate 20 can only move along the axial direction of the bidirectional lead screw 19.

[0039] Working principle: In use, firstly, two take-up drums 8 are fitted onto the drive column 7, and the take-up drums 8 are fixed to the drive column 7 through the cooperation of screw holes 10, fixing seats 11, mounting holes 12 and wing screws 13. Then, the two first motors 17 are started to drive the two conveying drums 15 and the two sponge drums 16 to rotate inward. The two sponge drums 16 push the cable to be stripped into the stripper body 1, so that the cable enters the stripper body 1 from the inlet 2 for stripping. In addition, the stripped inner core and outer tube are output from the outlet 3. Then, the stripped inner core is inserted into a take-up drum. Between the two clamping plates 20 inside the drum 8, the rotating lever 21 drives the bidirectional lead screw 19 to rotate. Through the threaded engagement between the bidirectional lead screw 19 and the two clamping plates 20, the two clamping plates 20 clamp and fix the inner wire core. In addition, the stripped outer wire tube is inserted between the two clamping plates 20 inside another winding drum 8. The two clamping plates 20 fix the outer wire tube. Finally, the second motor 6 is started to drive the transmission column 7 and the winding drum 8 to rotate. The winding drum 8 winds up the stripped inner wire core and outer wire tube, and at the same time pulls the stripped cable in the stripping machine body 1.
