[0002] As is well known, a vertical film blowing machine is a device widely used in the plastic processing industry. Its working principle is to put plastic particles into the hopper of an extruder, heat and melt them to form high-viscosity molten plastic, which is then pushed by the screw of the extruder to the die head. In the die head, the molten plastic is extruded through the gap of the die to form a circular film bubble shell. This bubble shell is inflated by air flow to keep its stable shape, and the stretching speed is adjusted by a stretching device, then cooled and solidified by a cooling system and pulled out, finally forming a continuous plastic film.

In the present invention, we only use them and do not improve their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they are in accordance with the requirements of their operation manuals, and will not be elaborated here.

[0026] In summary, the working principle of the vertical film blowing machine and the film blowing method is as follows. Before use, the film blowing group 2 is installed relative to the film blowing machine body 1, and the vertical box body 3 is set to a matching position relative to the film blowing group 2. The control power supply is installed for the film blowing machine body 1, the axial flow fan 9, the electric heating tube 10, the plasma emission end 11 and the rotating body storage structure. The granular raw material for extrusion is loaded into the film blowing machine body 1. When in use, the film blowing machine body 1 is started. The film blowing machine body 1 is powered on and operates to heat the granular raw material, and the melted granular raw material is injected into the film blowing group 2. After being processed by the film blowing group 2, a plastic film is output. A curved guiding column is provided on the film blowing group 2, and the guiding column can assist in guiding the output plastic film. The plastic film guided by the guiding column is controlled to be guided into the vertical box body 3 through the guiding cutting roller 4, and then sequentially bypasses the primary turning roller 5, two adjacent turning rollers 7 and a final turning roller 6 in the vertical box body 3, and finally forms winding storage through the rotating body storage structure. Since the rotating body storage structure has a power traction effect on the plastic film wound relative to it, it will form a traction drive on the plastic film in the vertical box body 3. Along with the movement of the plastic film, the electric heating tube 10 is energized to generate heat, and the axial flow fan 9 is energized to form air flow. Therefore, when the electric heating tube 10 and the axial flow fan 9 operate in cooperation, they can heat the plastic film passing through the primary turning roller 5 and the final turning roller 6. At the same time, when the plastic film passes through the plasma emission end 11, the plasma emission end 11 emits plasma to modify the surface of the plastic film to improve the surface performance.

[0027] Further, when the swivel storage structure winds and stores the plastic film, an inner support cylinder 16 needs to be installed on the corresponding winding roller 15 in advance so that the plastic film is wound around the inner support cylinder 16. This can avoid the difficulty of unloading the plastic film caused by directly winding the plastic film on the winding roller 15. When the corresponding winding roller 15 winds the plastic film, the external electromagnet 23 should be controlled to be in the power-off state first. At this time, under the elastic action of the sleeve spring 27, the sliding transmission frame 24 will be pushed to move closer to the external electromagnet 23. During this movement process, the sliding transmission frame 24 will be pulled out relative to the insertion drive hole 29, and the driving effect of the sliding transmission frame 24 on the main rotating disk 13 will fail. When the servo motor 12 is powered on and running, when driving the synchronous belt wheel 19 to rotate through the synchronous transmission belt 21, the synchronous belt wheel 19 will only drive the rotating cylinder 17 to rotate. When the rotating rotating cylinder 17 drives the sliding transmission frame 24 to rotate, it will not drive the main rotating disk 13 to rotate anymore. And because the movement of the sliding transmission frame 24 will drive the cylindrical frame 31 to move, the movement of the cylindrical frame 31 will cause both inner support sliding rods 25 to be pushed out relative to the main rotating disk 13 through the two transmission rods 32, thereby providing the main rotating disk 13 with the function of inner support rotation limit in the rotation port 14. After that, control one of the magnetic transmission components corresponding to the transmission gear 18 installed on the winding roller 15 to operate. When the rotating cylinder 17 rotates to drive the driving gear 20 to rotate synchronously, the rotation of the corresponding transmission gear 18 is driven, and finally the rotation drive of the corresponding winding roller 15 is achieved. When the magnetic transmission component operates, the internal electromagnet 37 is powered on to generate an electromagnetic field that acts on the magnetic attraction column 36, overcoming the elastic action of the position separation spring 33 and causing the sliding mounting frame 34 to form a relative displacement in the sliding groove 35, thereby realizing the position adjustment of the corresponding cutting-in gear 38, so that the cutting-in gear 38 can be meshed and cut into the driving gear 20 and meshed and cut into the transmission gear 18. After that, when the driving gear 20 rotates again, it can drive the cutting-in gear 38 meshed with it to rotate. The rotation of the cutting-in gear 38 can realize the rotation drive of the transmission gear 18 corresponding to it, and finally realize the rotation drive and control of the winding roller 15 to facilitate the winding and storage operation of the plastic film. When the internal electromagnet 37 is powered off, under the elastic reset action of the position separation spring 33, the cutting-in gear 38 will move away from the driving gear 20 and the transmission gear 18, so that the driving effect of the driving gear 20 on the transmission gear 18 fails. When the winding roller 15 for the winding operation has completed the winding operation of a sufficient amount of winding film, the power supply of the external electromagnet 23 is turned on. After the external electromagnet 23 is powered on to generate an electromagnetic field, it will act on the permanent magnet block 28 to cause the sliding transmission frame 24 to be inserted into the insertion drive hole 29, so that the transmission effect between the sliding transmission frame 24 and the main rotating disk 13 takes effect. And because the movement of the sliding transmission frame 24 will also pull the two inner support sliding rods 25, causing the two inner support sliding rods 25 to move synchronously and be received relative to the main rotating disk 13,Afterwards, the rotational limit between the main rotating disk 13 and the rotating port 14 fails. When the servo motor 12 is powered on and operates to drive the rotating cylinder 17 to rotate, the rotating cylinder 17 can drive the main rotating disk 13 to rotate through the sliding transmission frame 24, thereby achieving the position adjustment drive for the two winding rollers 15, so as to facilitate replacing the winding roller 15 after the winding operation is completed, and another winding roller 15 is put into application. And to ensure that the plastic film does not slip at the initial stage of winding around the inner support cylinder 16, it can be fixed manually or by adding forms such as tape sticking until the plastic film does not slip relative to the inner support cylinder 16, and then the winding operation of the plastic film can be started. After the plastic film is wound around one inner support cylinder 16 and then around the other inner support cylinder 16, the cutting operation of the plastic film between the two inner support cylinders 16 can be realized with the manual assistance of the operator or with the assistance of additional cutting equipment.
