Abstract

The invention relates to the technical field of packaging films, and provides a preparation device of a fruity beverage packaging film. The preparation device comprises a screw rod, the outer wall of the screw rod is movably connected with a conveying pipe, the top of the screw rod is fixedly connected with a rotating shaft, the left side and the right side of the rotating shaft are fixedly connected with transverse frames, the ends, away from the rotating shaft, of the transverse frames are fixedly connected with limiting plates, and the outer walls of the transverse frames are slidably connected with an unfolding frame. According to the fruity beverage packaging film and a preparation process thereof, a connecting plate slides downwards due to gravity and drives an arc block to move downwards, reset springs are compressed due to the fact that extrusion blocks are extruded at the beginning, when the connecting plate drives the arc block to move downwards, the arc block does not extrude the extrusion blocks any more, the extrusion blocks are rebounded by the reset springs, so that the extrusion blocks drive push rods to move, the resistance of rheostats is increased by means of the push rods , so that the rotation speed of the screw rod is reduced, the feeding speed of rotation of the screw rod is maintained, and the situation that the raw material melting speed fails to follow the feeding speed is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a fruity beverage packaging film and a preparation process thereof. Background technique [0002] Packaging film is used for winding packaging to make the packaging more stable and tidy. With the development of the times, packaging film not only plays the role of winding packaging and protection, but also makes it easy to move the packaged object, and the packaging film also makes the protected object oxidized . [0003] In the prior art, during the reproduction process of fruity beverage packaging film, the screw rod stalls, which will cause the progress of raw material feeding to change, making the thickness of the extruded film uneven, and feeding too fast, the raw material cannot be completely melted, which will make the The quality of the film deteriorates, and the amount of feed is unstable, causing the film to break. [0004] Therefore, the demand for high-reliab...
