The film roll installation roller 24 is arranged on the frame 1 and is tangent to the rubber wheel 21 driven by the synchronous motor, and the film roll installation roller 24 is tangent to the film roll roller 25 . During work, the film roll 4 is located on the film roll installation roller 24 and is driven by the synchronous motor drive rubber wheel 21 so that the film is delivered to the film and tape transmission mechanism, and the film and tape transmission mechanism transport the film to the place of use. The relationship between the unwinding speed n of the film roll installation roller 24 and the film feed speed V is: V constant=2πnr, where n is the rotating speed, and r is the radius of rotation of the film roll. Film roll roller 25 two ends are provided with bearing respectively, and film roll installation roller 24 is located on the two bearings of tangent.

The rubber wheel 21 driven by the synchronous motor is the power drive for unwinding the film roll, and cooperates with the weight 22 to realize synchronous unwinding, and the speed of the synchronous motor can be adjusted according to demand. And swing arm 23 is to guarantee that film reel can be pressed on the film reel when big roll and small roll, realizes stable transmission. Swing arm 23 is hinged on the frame, and its hinged end is equipped with bearing, and rotates flexibly. The counterweight hammer 22 is to adjust the pressing force of the rubber wheel driven by the synchronous motor to ensure the torque required for the transmission, and the weight of the counterweight can be increased or decreased according to the demand. The film installation roller 24 inserts the roller into the inner hole of the film roll, the chucks at both ends are locked, and is placed on the film roll roller 25 to realize the synchronous rotation of the roll and the film roll. In addition, the adhesive film installation roller 24 is located on the two bearings tangent to the adhesive film rolling wheel 25, so it can rotate flexibly. Furthermore, there is a positioning bayonet on it, which prevents the deviation and axial movement of the film roll. Film reel roller 25 two ends are installed two bearings respectively, and roller shaft is placed in tangency between two bearings, thereby guarantees that roller shaft rotates flexibly.

The film and tape conveying mechanism includes a film hot-pressing connector 31 , a film fast-feed conveying roller 32 , a tape storage tank 33 , a film tensioning roller 34 and a supporting roller 35 . Film hot-pressing connector 31, tape storage tank 33, film tensioning roller 34 and support flat roller 35 are arranged on the frame in turn, and film fast-feed conveying rollers are installed at both ends of the slot of tape storage tank 33 Stick 32.
