Description

Technical Field

[0001] The utility model relates to the technical field of protective film blowing bubble stabilizing frame structures, in particular to a bubble stabilizing frame structure used for protective film blowing processing equipment. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into film. The molten plastic is filtered through the machine head to remove impurities and comes out from the die head. It is cooled and inflated by the air ring and then passed through the bubble stabilizing rack, herringbone plate, traction roller, and winding to roll the finished film into a tube. The bubble stabilizing rack plays an important role in the protective film blowing process and meets the needs of protective film blowing processing.

[0003] The bubble stabilizing frame structure on the market is generally used as a guiding component to guide the protective film cooled by the air ring to the herringbone plate through conveying. During the conveying process, the protective film may not fit the inner wall or expand well, resulting in a decrease in the yield of the protective film, causing certain economic losses to the enterprise. Therefore, we propose a bubble stabilizing frame structure for protective film blowing processing equipment. Utility Model Content

[0010] Preferably, the air inlet end of the sealing connection seat is connected to an air inlet pipe, and the upper end of the air inlet pipe is connected to an external threaded connector.

[0011] Preferably, the air intake pipe is threadedly connected to a pump pressure input pipe via an external threaded connector.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the bubble stabilizing frame structure for protective film blowing processing equipment is used, the multiple second fixed seats and the first fixed seat form a complete bubble stabilizing frame structure. Through the bubble stabilizing frame structure, the demand for smooth transportation of the protective film intended for film blowing can be effectively met, and the situation in which the inner walls of the protective film are closely attached to each other during the film blowing process can be reduced, thereby providing the necessary transportation requirements for the production of the protective film.

At the same time, to ensure that the protective film can be expanded as much as possible, an electrostatic roller is fixed on the surface of the inner solid plate. Through the principle of thin film electrostatic adsorption and the internal air pressure push of the protective film, the requirement of the protective film to expand to the surroundings as much as possible is met, the possibility of the inner walls of the protective film sticking to each other is reduced, and the yield rate of the protective film is improved.

[0014] The inner solid disk serves as a constraint protection for the protective film. Multiple inner solid disks cooperate with each other to form a concentric circle structure.
