DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] An automatic oiling device for escalator roller waterproof cover, such as Figure 1 and Figure 3 As shown, it includes a mounting frame 1, a servo motor 2, a belt 3, a roller 4, a conveyor belt 5, a positioning mold 6, a connecting pipe 7, a control valve 8 and a control mechanism 9. A support frame is connected to the upper left side of the rear portion of the mounting frame 1, and the servo motor 2 is connected to the support frame. The support frame supports the servo motor 2, and a transmission wheel is connected to the output shaft of the servo motor 2.

The belt 3 is wound around the two transmission wheels, and the conveyor belt 5 is connected between the rollers 4. Twelve positioning molds 6 are connected to the upper side of the conveyor belt 5. The positioning mold 6 is a hollow cylinder, which is convenient for positioning and fixing the escalator roller. The connecting pipe 7 is connected to the upper rear side of the supporting frame, and the control valve 8 is connected to the lower left side of the connecting pipe 7. The bottom of the control valve 8 is connected with a screw through a thread, which is convenient for docking with the rotating frame 102.
