The cable guide includes a guide cylinder vertically arranged at one end of the paint box, with its lower portion immersed in the paint and a wire inlet at its bottom. The top of the guide cylinder is located above the paint box and has a wire outlet. This utility model prevents paint from leaking from the bottom of the paint box while simplifying the device structure and saving production costs.

[0004] However, the above utility model patent still has some shortcomings:

[0005] During the use of the above-mentioned utility model patent, the enameled wire is painted from the bottom of the paint roller using the paint in the paint box. The paint is prone to solidification if it remains stationary in the paint box for a long time, and the operator needs to try to stir and shake the paint in the paint box. In addition, the paint in the paint box is in direct contact with the outside air, which is easily contaminated with dust and also emits irritating odors in the working environment.
