Principle of operation

When the film blowing system starts from a static state, a material enters the machine body 10 from the hopper 27, the heating coil 11 starts to heat to a certain temperature, the material is melted into a liquid state in the machine body 10, air on the upper side of the air compression piston 26 in the air compression piston cylinder 25 close to the heating coil 11 is heated to expand, the air compression piston 26 moves downwards, the machine head motor 24 starts to drive the toothed ring 23 to rotate, the heating coil 11 sequentially passes through the air compression piston cylinders 25, the expanded air in the air compression piston cylinders 25 is cooled and contracted after leaving the heating coil 11, the material is sucked from the feeding ball 29, when the heating coil 11 passes through the air compression piston cylinder 25 sucked with the material again, the air expands again, the material is pressed to the core mold 18 from the discharging ball 30, and the air compression piston cylinders 25 sequentially operate to extrude the material from a gap between the die mold 19 and the core mold 18. When the material is discharged unevenly, the size of the gap is adjusted by rotating the core die adjusting plate 14 and the die adjusting plate 21, so that the film is produced evenly. At the same time, the air pump 12 is started, the air blowing channel 17 starts blowing air, and the blow molding operation starts.

At this time, the film is rolled after being blown, the film reaches the machine frame 40, the film is positioned between the rollers 38 at the upper side and the lower side, the rollers 38 rotate, and the linear speed at the outer side is consistent with that of the film. When the stretching sleeve 47 rotates along with the roller 38 and contacts with the reset baffle 39, when the stretching sleeve rotates to a side far away from the film, the hook-shaped position of the stretching block 48 is clamped at a side, far away from the stretching spring 45, of the supporting block 46 due to the acting force of the reset baffle 39, when the stretching sleeve 47 rotates to contact with the film, the stretching wheels 50 at the upper side and the lower side are contacted and mutually extruded, the stretching block 48 moves towards the direction of the extrusion spring 49, the hook-shaped position of the stretching block 48 is separated from the supporting block 46, the stretching sleeve 47 drives the stretching wheels 50 to move towards the direction of the rack 40, the tension spring 53 is stretched to play a role in buffering, and the film is straightened towards two sides. When the film is stretched but the force of the tension spring 45 is still present and the tension spring 53 is pulled to the limit, in order to prevent the film from being broken, the tension rod 51 compresses the protective film spring 52 to separate from the tension wheel 50 and enter the rotating shaft block 54, the tension wheel 50 starts to rotate around the rotating shaft block 54, the contact surface of the tension wheel 50 and the film is changed from sliding friction to rolling friction, and the film is ensured not to be broken by over-tension.
