Description

Technical Field

[0001] The utility model relates to the technical field of PTFE air purification membrane production, in particular to an electrostatic elimination device for a PTFE air purification membrane degreasing tractor. Background Technique

[0002] The air purification membrane is made of polytetrafluoroethylene as raw material, and after being expanded, calendered and biaxially stretched, a microporous film is formed. During the winding process of the film, it is easy to adsorb dust particles in the air due to the static electricity on the surface, which affects the subsequent use. Therefore, an electrostatic elimination bar is usually used to eliminate the static electricity on the surface of the film. For example, a winding device for aluminum film processing disclosed in Chinese Patent CN215222560U includes a winding table and a winding assembly arranged on the winding table. The winding assembly includes a traction mechanism, a correction mechanism, a transfer mechanism and a winding frame arranged on the winding table in sequence. The traction mechanism is arranged at one end of the winding table, the winding frame is arranged at the other end of the winding table, a winding roller is arranged on the winding frame, the correction mechanism is used to adjust the transmission state of the aluminum film traction by the traction mechanism, and the transfer mechanism includes a transfer frame, a transfer roller and an inclined frame. The transfer frame is arranged on the winding table, the transfer roller is arranged on the transfer frame, the inclined frame is arranged in the middle of the transfer frame, and an electrostatic elimination bar is arranged at the top of the inclined frame. The electrostatic elimination bar is close to the aluminum film conveyed between the transfer roller and the winding roller.

[0003] In order to eliminate the static electricity on the surface of the PTFE air purification membrane, the existing degreasing tractor needs to separately set up a mounting frame to fix the electrostatic elimination bar. The installation position of the electrostatic elimination bar is fixed, resulting in it being difficult for the electrostatic elimination bar to effectively ensure the distance from the air purification membrane, and the electrostatic elimination effect is not good.
