[0002] Winding machine is one of the key equipment in the film blowing production line, and automatic winder is widely used. To achieve normal winding, the winding air shaft must be in contact with the winding machine rubber roller and maintain appropriate pressure. The existing winding swing arm adjustment mechanism has one air shaft pressure arm on each side of the winder. The left and right swing arms are pressed by two left and right cylinders to make the winding air shaft contact with the rubber roller and maintain a certain pressure. The swing arm and the swing arm shaft are connected by the swing arm fixing half screw. During the initial adjustment, the winding air shaft should be placed in the swing arm working position, the fixing screws of the swing arms on both sides should be loosened, and the swing arm and half should be loosened. Under the force of the cylinder, the winding air shaft and the winding rubber roller are fully in contact, and then the screws are tightened. However, in the production of blown film, the half and the swing arm will often become loose after long-term use, resulting in inconsistency between the two swing arms, affecting normal winding.

[0006] Preferably, a resistance wire is provided in the clamping shaft.

[0007] Through the above scheme, the setting of the resistance wire heats the pressing shaft to soften the film it abuts against, so that the film can be rolled up on the winding roller tightly without generating large gaps, thereby avoiding the situation of frequent replacement of the winding shaft.

[0009] Through the above scheme, the arrangement of the first motor, the pull rope and the coil makes it easy to adjust the positional relationship between the clamping shaft and the winding roller, thereby facilitating the replacement of the winding roller.

[0010] Preferably, the first motor is connected to a controller, and the controller is connected to the winding mechanism; the controller is linked to the winding motor via electrical signals.

[0011] Through the above scheme, the provision of the air device facilitates the control of the operation of the first motor and the winding motor, thereby simplifying the operation.

[0012] Preferably, the winding motor is connected to the winding roller; one end of the winding roller is connected to a first gear, a chain belt is connected to the first gear, the other end of the chain belt is sleeved with a second gear, one end of the second gear is meshed with a third gear, the third gear is connected to the winding motor, and the winding motor is connected to the winding mechanism.
