The invention discloses a cross-linked rubber line powder coating device, and relates to the technical field of rubber line production, the cross-linked rubber line powder coating device comprises a base, a nicking assembly and a powder coating assembly, the outer side of the top of the base is provided with a winding seat, the end part of the winding seat is provided with a first motor, and the outer end of the winding seat is wound with a cross-linked rubber line; a nicking assembly is arranged at the top end of the base. According to the device, the pushing seat is electrically controlled to work, the first creasing head can press longitudinal shallow marks on the surface of the cross-linked rubber line, after the first creasing head completes creasing on the cross-linked rubber line, the first motor works to drive the cross-linked rubber line to be wound, the position, where the longitudinal marks are pressed, of the cross-linked rubber line can move to the pushing block, and at the moment, the electric push rod works to drive the cross-linked rubber line to be wound. By means of the operation, the device can press net-shaped indentations on the surface of the cross-linked rubber line, and the contact area of mica powder and the cross-linked rubber line in the follow-up powder coating process can be increased by pressing the indentations.

This utility model discloses a carton flipping device, relating to the field of carton storage and transportation technology. It includes a main body with a conveyor belt rotatably connected to its inner side. A pusher plate is fixedly connected to the outside of the conveyor belt. A flipped carton is placed on the upper side of the conveyor belt between two sets of pushers. The flipped carton has creases on its outer surface, and a box stud is riveted to its end. A baffle is fixedly connected to the upper end of the main body. An auxiliary flipping mechanism is installed on the upper side of the main body, and a stacking mechanism is fixedly installed at the end of the main body.
