Wherein, the diameter of the opening at the two sides of the limiting groove 401 is larger than that of the top position, the limiting groove 401 is used for cutting off the electricity of other electrodes 6 which are not positioned in the vertical direction and does not work, so as to play a role of protection, the top 801 is U-shaped, the bottom of the top is jointed with the outer ring of the dielectric plate 7 without friction, the height of the inner bottom surface of the top 801 is lower than that of the electrodes 6, the inside of the corrugated pipe 802 is fixedly provided with an extension spring, the top 801 is jointed at the outer side of the dielectric plate 7 and is propped against the side edge of the film 18 by the side edge, thus, the U-shaped top 801 and the corrugated pipe 802 can shield the electrodes 6 with more width than the film 18 on both sides, so that the electrodes do not form corona effect with the dielectric plate 7, and the top 801 and the corrugated pipe 802 are made of insulating materials, and meanwhile, the spring is arranged in the corrugated pipe 802, so that the top 801 can guarantee certain abutting pressure, and adjustment is convenient.

Similarly, the opening of the adjusting groove 901 on the side close to the film outlet direction of the thin film 18 is equal to the length of the two dielectric plates 7, the opening of the adjusting groove 901 on the side close to the film inlet direction of the thin film 18 is equal to the length of the heat dissipating groove 201, the driving roller 16 movably mounted on the bottom of the side close to the small opening of the adjusting groove 901 has strong magnetic force, the magnetic force of the magnetic block 17 on the side of the dielectric plates 7 is greater than the magnetic force between the dielectric plates 7, the driving roller 16 has strong magnetic force to attract the two dielectric plates 7 at the middle position of the bottommost part on the roller 2, then the driving roller 16 is driven to move forward continuously and attracted to the edge by the magnetic block 17 on the side close to the large opening of the adjusting groove 901, and then after the magnetic force of the driving roller 16 is reduced, the dielectric plates 7 are attracted back again by the magnetic chuck 202, but the attracted dielectric plates 7 are already at the edge position, this achieves that the adjustment of the dielectric plate 7 by the change of the magnetic force and the transmission of the rotation ensures the uniformity of use.

The working principle is that when the device works, a power supply is firstly switched on to turn on a switch, a film 18 passes through the outer ring of a roller consisting of dielectric plates 7 on a roller 2 through the guide of a guide roller 3, at the moment, a conductive core 12 transmits current to a conductive head 13 through a lead, the current of the conductive head 13 received by the side edge of an electrode 6 in the vertical direction is transmitted and then electrified, corona is formed between the conductive core and the dielectric plate 7 at the bottom, the corona treatment is carried out on the film 18 by utilizing the corona, after the width of the film 18 is narrowed, a top 801 is pushed towards the middle under the action of the elastic force in a corrugated pipe 802 and the corrugated pipe 802 is elongated, the top 801 and the corrugated pipe 802 completely cover the electrode 6 which is not positioned above the film 18, so that the part generating the corona is reduced, the content of ozone is reduced, the corona treatment of the film 18 is facilitated, and after the electrode 6 works for a long time, a rotating shaft 5 can be rotated to enable the next electrode 6 to work in the vertical direction, and the electrode 6 which is just finished is rotated into the limit groove 401;

meanwhile, in the process of corona treatment, when the adjusting device 9 is started, the dielectric plate 7 of the portion just subjected to corona treatment is rotated to the bottom position along with the rotation of the roller wheel 2, the two dielectric plates 7 in the middle are attracted into the adjusting groove 901 under the action of strong magnetic force of the bottom driving roller 16 close to the small opening side of the adjusting groove 901, the dielectric plates 7 on the two sides are moved to the middle and aligned under the action of mutual magnetic force, the driving roller 16 in the adjusting groove 901 is powered by the roller wheel 2 and the driving device 10 to drive the attracted dielectric plates 7 and the magnetic chuck 202 to keep the same angular velocity, then when the dielectric plates are driven to the large opening side of the adjusting groove 901, the two electrolyte plates 7 are respectively attracted to the two sides under the action of the magnetic block 17, then the magnetic force action of the driving roller 16 is lost, and the dielectric plates 7 are attracted upwards and clamped together under the action of the magnetic chuck 202, this completes the adjustment of the dielectric plate 7.
