The utility model belongs to the technical field of corrugated pipe coating, and particularly relates to PVC corrugated pipe surface coating equipment which comprises a corrugated pipe and a fixing frame. The coating unit is internally provided with two coating rollers which are oppositely distributed on the two sides of the fixing frame in a staggered mode, and the outer side of the coating unit is provided with arc-shaped protrusions for filling the wave troughs of the fixing frame; the rotating rods are located at the two ends of the coating roller, are perpendicular to the section of the coating roller and extend in the direction of the side wall of the fixing frame, and the rotating motion drives the coating roller to roll. According to the utility model, the coating mechanism does not need to move circumferentially, and the coating mechanism can form traction on the pipe body, so that continuous coating operation is achieved, support is formed, and deformation and sagging of the pipe body are prevented.

The invention discloses a device and a method for preparing a solid-state battery cell material through magnetothermal evaporation and magnetic deposition, and the method specifically comprises the following steps: taking a roll of polymeric membrane to be unfolded as a substrate, and forming an aluminum metal current collector I on one side of the polymeric membrane through evaporation and deposition; an aluminum metal current collector II is formed on the other side of the polymeric membrane, and the surface of the aluminum metal current collector I is sequentially coated with a positive electrode material layer, an electrolyte layer and a negative electrode material layer; and taking another roll of polymeric membrane as a substrate after being unfolded, forming a copper metal current collector I on one side of the polymeric membrane through evaporation deposition, forming a copper metal current collector II on the other side of the polymeric membrane, and carrying out calendering compounding on the polymeric membrane attached with the negative electrode material layer and the polymeric membrane on the side of the copper metal current collector I to obtain the lithium ion battery negative electrode material. The problems of high production cost, low production efficiency and low drying efficiency in the preparation process of an existing solid-state battery cell material are solved.
