[0021] In view of the technical problems described in the background art, as Figures 1-7As shown, a film machine winding electrostatic adsorption device is provided, comprising: a guide rack 1, the guide rack 1 is provided with a guide wheel set 2, the guide wheel set 2 is arranged along the winding direction of the film roll; slide rails 3 are respectively arranged on both sides of the discharge direction of the guide rack 1; a base plate assembly 4 is respectively arranged on the slide rails 3, and the base plate assembly 4 can move longitudinally along the slide rails 3; an electrostatic generating device 5 is installed at both ends of the base plate assembly 4; a cutting device 6 is installed at both ends of the base plate assembly 4, and the cutting device 6 is arranged on one side of the electrostatic generating device 5; a telescopic device 7 is respectively arranged below the slide rails 3, and the telescopic end of the telescopic device 7 is connected with the base plate assembly 4; a turnover tower 8 is provided with a turnover frame 9, and the turnover frame 9 is provided with a first inflatable shaft 10 and a second inflatable shaft 11 for collecting film rolls; a control device is used for receiving instructions and outputting instructions; wherein when the first inflatable shaft 10 winds the film roll and changes the roll, the turnover frame 9 drives the first inflatable shaft 10 and the second inflatable shaft 11 to switch, the electrostatic generating device 5 is driven to move to the paper tube of the second inflatable shaft 11 by the telescopic device 7 to discharge, so that the paper tube is attached to the film roll; the cutting device 6 drives the film roll to cut.

[0022] The present application provides a film machine winding electrostatic adsorption device, mainly used in the process of winding the film roll, through the electrostatic adsorption effect to make the film roll closely attached to the paper tube, and automatically cut the film roll when changing the roll, to ensure the continuity and efficiency of the film roll winding process. The above technical solution is the specific embodiment of the present application: the guide rack 1 is used to guide the running direction of the film roll in the winding process, and the slide rails 3 are used to provide guidance and support for the movement of the base plate assembly 4. The base plate assembly 4 is used as the mounting platform of the electrostatic generating device 5 and the cutting device 6, which can be adjusted according to the position of the film roll.
