[0024] The application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 The electrostatic elimination device disclosed in the application comprises at least one set of electrostatic elimination mechanism, which is used to contact the roller and / or the film. The electrostatic elimination mechanism comprises a support rod 1, a conductive brush 2, an ion blower, an air supply pipe and a lead wire. In the embodiment, the conductive brush 2 and the support rod 1 are both two sets and one-to-one corresponding, and the conductive brush 2 is installed on the support rod 1. The support rod 1 is provided with a plurality of flow holes 11 which are not communicated with each other. The conductive brush 2 comprises a support column 21 and a conductive fiber 22. In the embodiment, the conductive fiber 22 is made of flexible material (such as carbon black fiber, conductive polymer fiber, conductive nylon wire, conductive plastic polyethylene wire, etc.), and the support column 21 is made of rubber material. The conductive fiber 22 has a plurality of roots and is arranged in a cylindrical shape and concentrically with the support column 21. The support column 21 is further provided with a plurality of air outlet holes 23 which are arranged in a ring shape and surround the cylindrical conductive fiber 22. The ion blower is connected to the pipeline and the electromagnetic valve through the air supply pipe and the plurality of flow holes 11, and the flow holes 11 and the air outlet holes 23 are communicated. The lead wire is connected to the conductive fiber 22 and grounded. In use, at least one set of conductive brush 2 contacts the film, and the air outlet hole 23 faces the contact position of the roller and the film.

[0026] The control system further comprises a control module and a notification module. The control module acquires the film parameters to make a judgment. The film parameters include the width. After the control module acquires the width, it makes a judgment. If the width is less than the length of a single conductive brush 2 (i.e. the length of the conductive brush 2 on a single support rod 1 along the length direction of the support rod 1), the control module controls the ion blower to run and controls the electromagnetic valve to run in turn, i.e. only one flow hole 11 is conducted at the same time. The state of the conductive fiber 22 is collected by the camera and judged, or the judgment is made by the pressure sensor in the flow hole 11. If it does not meet the standard, i.e. the air outlet hole 23 is blocked, the position of the flow hole 11 is judged, and the width and the relative position of the support rod 1 are recalculated. Then the position of the corresponding support rod 1 is notified, so that the operator adjusts the position of the support rod 1 according to the position information.

[0027] When the width of the film is greater than the length of a single set of conductive brush 2, the control module controls the ion fan to operate, and controls the electromagnetic valve to operate in turn, the state of the conductive fiber 22 is collected and judged by the camera, or is judged by the pressure sensor in the overflow hole 11, if it does not meet the standard, that is, there is a blockage in the air outlet hole 23, the position of the overflow hole 11 is judged, and the width and the relative position of the supporting rod 1 are recalculated. Then the positions of the two sets of supporting rods 1 are notified, so that the operator adjusts the position of the supporting rod 1 according to the position information.

[0028] The implementation principle of the embodiment is: in use, the combination of the ion fan and the conductive fiber 22 makes the removal effect of static electricity better, that is, the gas generated by the ion fan is discharged through the air outlet hole 23, the position of the conductive fiber 22 is corrected, the contact effect of the conductive fiber 22 with the roller and / or the film is better, and then a good static electricity removal effect is achieved.

[0029] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
