Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to an edge inserting device for a film blowing machine and a film blowing machine. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into thin films. The principle is to add dry polyethylene particles into the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface produces a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, the plastic gradually melts due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and the external heating of the barrel. The molten plastic is filtered through the die head to remove impurities and comes out from the die head. It is cooled by the air ring, blown, and rolled into a tube through the herringbone plate, traction roller, and winding. After searching, application number 202221988710.6 discloses a new type of edge insertion device for film blowing machine, which belongs to the technical field of film blowing machine, including a conveying frame and a base arranged under the conveying frame, a receiving frame is fixedly welded on the top wall of the conveying frame, a mobile motor is welded on the side wall of the receiving frame, and a double-thread screw coaxially connected to the output shaft of the mobile motor is provided on the inner side of the receiving frame, wherein both ends of the double-thread screw are threadedly sleeved with upper slide seats, and the threads at both ends of the double-thread screw have opposite rotation directions, and a limiting slide bar welded with the receiving frame is provided above the double-thread screw, wherein two upper slide seats are slidably sleeved on the limiting slide bar, and the bottom walls of the two upper slide seats are provided with hydraulic telescopic rods and vertical plates, and the two ends of the hydraulic telescopic rods are respectively welded and fixed to the upper slide seat and the vertical plate, and cutting motors are welded to the opposite side walls of the two vertical plates.
