[0024] In this embodiment, the spacing adjustment mechanism includes a bidirectional ball screw 21, which is rotatably connected in a groove. The groove is opened in the middle of the upper end surface of the support platform 2. The first ball screw pair 22 and the second ball screw pair 27 are symmetrically installed on both sides of the bidirectional ball screw 21. The top surface of the first ball screw pair 22 is fixedly connected to the first bracket 23, and the top surface of the second ball screw pair 27 is fixedly connected to the second bracket 26. The first straightening roller 24 is installed in the first bracket 23, and the first straightening roller 24 is rotatably connected to the first carrier 236. The second straightening roller 25 is installed in the second bracket 26, and the second straightening roller 25 is rotatably connected to the second carrier 237. The spacing between the first straightening roller 24 and the second straightening roller 25 can be adjusted so that it is suitable for straightening processing of cables of different specifications.

[0025] In this embodiment, the cable outlet 1 is fixedly connected to one side of the upper end surface of the base 3, and the support platform 2 is fixedly connected to the middle of the upper end surface of the base 3, which can output the cable and facilitate the straightening process of the cable.

[0026] In this embodiment, the output end of the first light emitter 231, the output end of the first light receiver 232, the output end of the second light emitter 233 and the output end of the second light receiver 234 are all connected to the input end of the controller, and the output end of the controller is connected to the input end of the first relay and the second relay, so as to facilitate the transmission of the light curtain blocking signal to the controller, and then the controller issues a corresponding instruction.

[0027] In this embodiment, the upper part of the first platform 236 is slidably connected in the first guide groove, and the first guide groove is opened at the top position in the first bracket 23. The upper part of the second platform 237 is slidably connected in the second guide groove, and the second guide groove is opened at the top position in the second bracket 26, thereby improving the guiding properties of the first platform 236 and the second platform 237 during movement.

[0028] In this embodiment, one end of the bidirectional ball screw 21 is connected to the output shaft of the variable frequency motor through a reducer. The variable frequency motor is located on one side surface of the support platform 2. The variable frequency motor is electrically connected to the external power supply through a connecting line, and can control the speed reduction rotation of the bidirectional ball screw.

[0029] Working principle: When the present invention is in use, the frequency conversion motor circuit is first connected, and the frequency conversion motor drives the bidirectional ball screw 21 to rotate, and the first ball screw pair 22 and the second ball screw pair 27 move to both sides or the center of the bidirectional ball screw 21 at the same time, and the first ball screw drives the first bracket 23 to move, and the second ball screw pair 27 drives the second bracket 26 to move, and the first bracket 23 drives the first straightening roller 24 to move, and the second bracket 26 drives the second straightening roller 25 to move. When the first straightening roller 24 and the second straightening roller 25 move to a specified distance, the frequency conversion motor is stopped, and then the cable outlet 1 passes the cable through the first straightening roller 24 and the second straightening roller 25, and the first straightening roller 24 and the second straightening roller 25 straighten the cable. When the straightness of one side of the straightened cable is insufficient, one end of the cable blocks the second straightening roller 25. A light curtain is formed between a light emitter 231 and a first light receiver 232. When the light curtain blocking signal is transmitted to the controller, the controller model is an AT89C51 single chip microcomputer. The controller issues a control instruction and connects the circuit of the first electric push rod 235 through the first relay. The first electric push rod 235 pushes the first carrier 236 to move. The first carrier 236 drives the first straightening roller 24 to move and increases the straightening force of the first straightening roller 24 so that the straightening force of the first straightening roller 24 is the same as that of the second straightening roller 25, and the cable is straightened. Similarly, when one end of the cable blocks the light curtain between the second light emitter 233 and the second light receiver 234, the controller controls the movement of the second electric push rod 238 through the second relay, and adjusts the straightening force of the second straightening roller 25 through the second electric push rod 238, thereby straightening the cable.
