The bottom of the cable is supported by the guide rail 1e, and the movement direction of the cable is guided, so that the cable can enter the working end of the next feeding wheel set 1 a. Can compress tightly transmission part of transmission assembly 1c through tensioning assembly 1d, the staff can also adjust the rate of tension through manual regulation tensioning assembly 1 d. When the cable passes through the last feeding wheel set 1a and enters the spraying mechanism 2, the controller sends a signal to the spraying mechanism 2, and the spraying mechanism 2 uniformly sprays oil mist on the peripheral wall of the cable after receiving the signal. The controller also sends a signal to the air drying mechanism 3, the working end of the air drying mechanism 3 surrounds the cable, the working direction of the air drying mechanism is inclined towards the direction of the spraying mechanism 2, the wind is blown towards the direction of the spraying mechanism 2 while being concentrated towards the peripheral wall of the cable, and the oil mist is blocked inside the spraying mechanism 2 by the input end of the spraying mechanism 2 so as to be fully contacted with the surface layer of the cable. And by this means, the oil mist is prevented from overflowing from the output end of the air drying mechanism 3, which is helpful for improving the working environment. The winding mechanism that sets up in air-dry 3 backs of mechanism is comparatively common, does not do here and gives unnecessary details, and the cable inlet wire rolling of accomplishing spraying and air-drying through winding mechanism further provides traction force for the motion of cable simultaneously.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
