[0020] Please refer to Figs. 1-3 A wire slot traction machine, comprising a body 1, a motor 2 is fixedly installed on the body 1, a traction roller 3 is fixedly connected to the output end of the motor 2, a fixed frame 4 is fixedly connected to the body 1, a fixed rod 5 is fixedly connected to the inner side of the fixed frame 4, a sliding plate 6 is slidingly connected to the outer surface of the fixed rod 5, a spring 7 is fixedly connected to the outer surface of the sliding plate 6, and the spring 7 is movably sleeved on the outer surface of the fixed rod 5, a rubber plate 8 is slidingly connected to the outer surface of the fixed rod 5, and the outer surface of the rubber plate 8 is fixedly connected to the end of the spring 7 away from the sliding plate 6, a plurality of arc grooves 9 are formed in the outer surface of the rubber plate 8, the sizes of the arc grooves 9 are slightly different, and the arc grooves 9 can adapt to cables of different sizes, a manual driving mechanism is arranged on the fixed frame 4, and a guide mechanism is arranged on the fixed frame 4.

[0021] Through the above technical solution, the motor 2 drives the traction roller 3 to rotate during use, thereby tractioning the cable. In this process, the traction position of the cable can be changed through the guide mechanism, and the distance between the two groups of sliding plates 6 can be adjusted under the action of the manual driving mechanism, thereby cooperating with the spring 7 to wrap the cable with the rubber plate 8 at a suitable flexible force, so that the cable passes through the corresponding arc groove 9.

[0022] Specifically, the manual driving mechanism comprises a guide shaft 10 fixedly connected to the inner side of the fixed frame 4, and a sliding seat 11 is slidingly connected to the outer surface of the guide shaft 10, and the bottom of the sliding seat 11 is fixedly connected to the top of the sliding plate 6.

[0023] Through the above technical solution, the guide shaft 10 is provided with two groups, and the two groups of sliding seats 11 jointly play a relative limiting role, so that the sliding seat 11 can only slide along the surface of the guide shaft 10 at a fixed track (moving closer or farther away from each other).

[0024] Specifically, the top of the fixing frame 4 is threadedly connected with a screw rod 12, the top of the screw rod 12 is provided with a rotating handle 13, and the bottom end of the rotating handle 13 is rotationally connected with a lifting platform 14.

[0025] Through the above technical scheme, the screw rod 12 passes through the top of the fixing frame 4 and is threadedly connected with the fixing frame 4, so that the screw rod 12 moves longitudinally during rotation.

[0026] Specifically, the inner side of the lifting platform 14 is fixedly provided with an upper shaft 15, the outer surface of the upper shaft 15 is rotationally connected with a swing arm 16, the inner side of the sliding seat 11 is fixedly provided with a lower shaft 17, and the outer surface of the lower shaft 17 is rotationally connected with the bottom of the swing arm 16.

[0027] Through the above technical scheme, the upper shaft 15 and the lower shaft 17 cooperate with the swing arm 16, and the three are cooperated to convert the lifting of the lifting platform 14 into the horizontal movement of the sliding seat 11.

[0028] Specifically, the guide mechanism includes a horizontal rod 18 fixedly connected to the inner side of the fixing frame 4, the outer surface of the horizontal rod 18 is slidingly connected with a guide platform 19, and the guide platform 19 is provided with a guide hole 20.

[0029] Through the above technical scheme, in the process of sliding the guide platform 19 along the horizontal rod 18 by actuating the push rod 21, the position of the cable passing through the guide hole 20 also changes.

[0030] Specifically, the top of the guide platform 19 is fixedly connected with a push rod 21, and the outer surface of the push rod 21 is slidingly connected with the inner side of the fixing frame 4.

[0031] Through the above technical scheme, the top of the fixing frame 4 is provided with a rectangular hole, which is used for facilitating the movement of the push rod 21, and the push rod 21 is used for manually adjusting the traction position of the cable.

[0032] Working principle: during use, the traction machine needs to be started to drive the traction roller 3 to rotate, so that the traction roller 3 can pull the cable, during which the cable passes through the arc grooves 9 on the surface of the rubber plate 8 and the guide holes 20 on the guide table 19, and the guide table 19 can be slid along the cross rod 18 by pulling the lever 21 during the traction process, so as to adjust the traction position of the cable, so as to smoothly pull the cable and avoid the situation that the cable is entangled and cannot be normally pulled. When the cable passes through the arc grooves 9 on the surface of the rubber plate 8, the corresponding height of the arc grooves 9 on the rubber plate 8 can be selected according to the specifications of the cable. Considering that the cable is prone to shaking and deviation during the traction process, which may cause the cable to be subjected to additional stretching and bending forces, the flexibility of the rubber plate 8 to the cable can be adjusted according to the diameter and type of the cable. At this time, only the rotating handle 13 needs to be manually rotated to drive the screw rod 12 to rotate, and the screw rod 12 will displace longitudinally during the rotation, thereby driving the lifting table 14 to move vertically. During this process, the two ends of the swing arm 16 will rotate along the upper shaft 15 and the lower shaft 17, respectively. At the same time, the swing arm 16 can push and pull the slide 11 through the lower shaft 17 during deflection, so that the two sets of slides 11 slide along the guide shaft 10 (the two sets of slides 11 move closer or farther away synchronously). During the movement of the slide 11, the slide 11 will displace synchronously, i.e. the two sets of slides 6 will push the rubber plate 8 through the corresponding springs 7, respectively. Finally, under the elastic action of the spring 7, the rubber plate 8 will exert a suitable flexible force on the cable at the arc groove 9, so that the cable is flexibly clamped by the two rubber plates 8 when passing through the arc groove 9. This flexible clamping design allows the cable to have a certain degree of freedom during the traction process, which means that the cable will not be subjected to unnecessary stress due to excessive rigidity of the clamping. At the same time, the design of the arc groove 9 can better fit the shape of the cable, reducing the sliding of the cable in the arc groove 9, thereby to some extent alleviating the shaking and deviation of the cable. Although the cable may still be affected by a certain shaking or deviation during the traction process, the elasticity and buffering performance of the rubber plate 8 in cooperation with the spring 7 can help to disperse these stresses. When the cable passes through the arc groove 9, the rubber plate 8 can absorb part of the stress, reducing the risk of damage to the internal wires or insulation layer of the cable due to stress concentration.

[0033] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
