[0042] The film blowing machine body 1, film blowing group 2, axial flow fan 9, electric heating tube 10, plasma emission end 11, servo motor 12, external electromagnet 23 and internal electromagnet 37 in this embodiment are all conventional equipment purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of the instruction manual, and will not be described in detail here.

[0043] 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. A 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 storage structure. The granular raw materials for extrusion are loaded into the film blowing machine body 1. When in use, the film blowing machine body 1 is started, and the film blowing machine body 1 is powered on to heat the granular raw materials, and the melted granular raw materials are injected into the film blowing group 2. After being processed by the film blowing group 2, the plastic film is output. A curved guide column is provided on the film blowing group 2. The guide column can form an auxiliary guide for the output plastic film, and control the plastic film guided by the guide column so that It is guided into the vertical box body 3 by the guide cutting roller 4, and then passes through the primary turning roller 5, two adjacent turning rollers 7 and a tail-stage turning roller 6 in the vertical box body 3 in sequence, and finally is wound and stored by the rotary storage structure. Since the rotary storage structure has a dynamic traction effect on the plastic film wrapped relative to it, it will form a traction drive on the plastic film in the vertical box body 3. As the plastic film moves, 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 are operated in conjunction, they can heat the plastic film passing through the primary turning roller 5 and the tail-stage 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 increase the surface performance.

[0044] Furthermore, when the rotating storage structure forms a winding storage for the plastic film, it is necessary to pre-install the inner support cylinder 16 on the corresponding winding roller 15 so that the plastic film is wound on the inner support cylinder 16. This can avoid the difficulty in unloading the plastic film caused by the plastic film being directly wound on the winding roller 15. When the corresponding winding roller 15 forms a winding operation for the plastic film, the external electromagnet 23 should be controlled to be in a power-off state. At this time, the elastic action of the set spring 27 will push the sliding transmission frame 24 to move closer to the external electromagnet 23. This movement process will cause the sliding transmission frame 24 to 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 energized and running, the synchronous pulley is driven by the synchronous transmission belt 21. During the rotation of 19, the synchronous pulley 19 will only drive the rotating drum 17 to rotate, and the rotating rotating drum 17 will not drive the main rotating disk 13 to rotate when driving the sliding transmission frame 24 to rotate, and because the movement of the sliding transmission frame 24 will drive the cylindrical frame 31 to form movement, the movement of the cylindrical frame 31 will cause the two inner support sliding rods 25 to be pushed out relative to the main rotating disk 13 through the two transmission rods 32, and then provide the main rotating disk 13 with the function of forming an inner support rotation limit in the rotation port 14, and then control a magnetic transmission component corresponding to the transmission gear 18 installed on the winding roller 15 to operate, so that the rotating drum 17 rotates and drives the driving gear 20 to form a synchronous rotation, thereby realizing the rotation drive of the corresponding transmission gear 18, and finally To achieve the corresponding rotation drive of the winding roller 15, when the magnetic transmission component is running, the built-in electromagnet 37 is powered on to generate an electromagnetic field acting on the magnetic column 36, which will overcome the elastic effect of the separation spring 33 and cause 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 form an engagement and cutting relative to the driving gear 20 and the transmission gear 18. After that, the driving gear 20 rotates again to drive the cutting-in gear 38 meshing with it to rotate, and the rotation of the cutting-in gear 38 can realize the rotation drive of the corresponding meshing transmission gear 18, and finally realize the rotation drive and control of the winding roller 15 to facilitate the winding and storage operation of the plastic film. After power is cut off, under the elastic restoring action of the separation spring 33, the cutting gear 38 will be separated from the driving gear 20 and the transmission gear 18, so that the driving action of the driving gear 20 on the transmission gear 18 becomes invalid. When the winding roller 15 of 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 energized and generates an electromagnetic field, it acts on the permanent magnet block 28 to prompt the sliding transmission frame 24 to be inserted into the insertion drive hole 29, so that the transmission action between the sliding transmission frame 24 and the main rotating disk 13 is effective. In addition, due to the movement of the sliding transmission frame 24, the two inner supporting sliding rods 25 are also pulled, so that the two inner supporting sliding rods 25 move synchronously and are both retracted relative to the main rotating disk 13.After that, the rotation limit between the main rotating disk 13 and the rotating mouth 14 fails. When the servo motor 12 is powered on and drives the rotating drum 17 to rotate, the rotating drum 17 can drive the main rotating disk 13 to rotate through the sliding transmission frame 24, and then achieve the position adjustment drive of the two winding rollers 15, so as to facilitate the replacement of the winding roller 15 after the winding operation is completed, and the other winding roller 15 is used in place. In order to ensure that the plastic film does not slip relative to the inner support cylinder 16 in the initial stage of winding, it can be manually fixed or added in a form such as tape until the plastic film and the inner support cylinder 16 do not slip, and then the winding operation of the plastic film can be started. After the plastic film is wound relative to one inner support cylinder 16 and then wound relative to the other inner support cylinder 16, the plastic film cutting operation between the two inner support cylinders 16 can be achieved with the manual assistance of the operator or with the assistance of additional cutting equipment.
