Hollow plate double-sided film covering device based on tension synchronous adjustment

Abstract

The utility model discloses a hollow plate double -sided film covering device based on tension synchronous regulation relates to hollow plate film covering technical field, including fixed roll axle, the bottom surface of fixed roll axle is provided with the transmission unit of can assist hollow plate feeding stable, the inside of transmission unit is provided with the activity unit of can to hollow plate carry out double -sided film covering, and transmission unit fixed mounting is in the base of fixed roll axle bottom surface, the utility model discloses through with two film rolls installation in the outer surface of fixed axle, and through the side plate fixed, ensure that two film roll direction is opposite, and the one end of film roll is passed the outer surface of pull rod, finally one end clamping of two film rolls between the clamping lever, in order to subsequent hollow plate carries out film covering operation, under the drive of transmission unit, hollow plate moves forward, passes between two pull rod, further extrudes between two clamping lever, hollow plate and film roll contact to this moment, and through motor drive biaxial screw rod rotates, make pull rod prop open the surface of two film rolls, with adjusting film roll tension.
