Abstract
A plastics film blowing device, comprising an extrusion device, a die head, a gable and a winding device. A top and a bottom cooling air rings are equipped above the die head. Both air rings are below the condensate line, and their annular air outlets are upward. Two cooling air rings of the plastics film blowing equipment of the present new utility can carry out air blast cooling for the foaming pipes in turn. The cooling effect above the circle of the foaming pipes is uniform, and can increase the cooling velocity without increasing the wind speed, therefore allow the foam pipe stable. The cooling is rapid and can improve the film production and quality.
Description
Technical field
The utility model belongs to the plastic processing machinery field, is specifically related to a kind of plastic membrane blowing equipment.
Background technology
In the technology of plastic foil blow molding, cooling vane plays effects such as cooling and stable bubble, and cooling procedure all has a significant effect for the quality of production and the speed of production of film, and the cooling velocity of cooling vane directly limits and determined the speed of production of film.
Traditional plastic membrane blowing equipment is all only established a cooling vane, therefore, and in order to improve the speed of production of film, people can only take to strengthen the mode of cold air blast velocity, and with the cooling velocity of hope raising film, but wind speed is excessive, cause the film bubble unstable conversely easily, influenced the blowfilm shaping quality.
In recent years, people have designed another kind of blown film equipment, it is provided with two cooling vanes, but wherein have only a cooling vane to be positioned at below the condensate line, another cooling vane then is positioned at more than the condensate line, and film steeps the moulding of having condensed fully more than condensate line, thereby the cooling vane that is positioned at more than the condensate line has little significance to the cooling velocity that improves the film bubble.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned shortcoming and a kind of plastic membrane blowing equipment is provided, and it can effectively improve film bubble rate of set, improves the blown film speed of production, and can avoid having influenced the blowfilm shaping quality.
For realizing above purpose, plastic membrane blowing equipment of the present utility model comprises pressurizing unit, die head, collapser, wrap-up, its main feature is, above die head, be provided with two cooling vanes up and down, two cooling vanes all are positioned at below the condensate line, and the ring-type air outlet of two cooling vanes is all towards the top.
Realization above-mentioned purpose scheme preferably is: the cooling vane that wherein is positioned at the below is near die head.
Realize that the better scheme of above-mentioned purpose is: the vertical range between two cooling vanes is adjustable up and down.
Up and down the air inlet of two cooling vanes preferably separately separate connection one typhoon machine is arranged.
The utlity model has following advantage and effect:
1, the utility model is owing to be provided with two cooling vanes below condensate line, and two cooling vanes are stacked up and down, after the bubble pipe is extruded, two cooling vanes can be successively to the cooling of drying of bubble pipe, cooling effect is even on the bubble pipe circumference all directions, need not rely on the raising wind speed to improve cooling velocity, makes the bubble pipe stable, cooling velocity is fast, can improve foil production speed and quality.
2, up and down the air inlet of two cooling vanes respectively separately separate connection one typhoon machine is arranged, can carry out independent regulation to the wind speed of two cooling vanes up and down.
3, the vertical range of two cooling vanes is adjustable up and down, can adapt to the production needs of the plastic sheeting of unlike material, different-thickness.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
The specific embodiment
Plastic membrane blowing equipment shown in Figure 1 comprises die head 1, collapser, wrap-up, pressurizing unit, above die head, be provided with two cooling vanes 2,3 up and down, two cooling vanes all are positioned at below the condensate line, each cooling vane is provided with air inlet and ring-type air outlet 22 (32), and the ring-type air outlet 22 (32) of two cooling vanes is all towards the top.The cooling vane 2 that wherein is positioned at the below is near die heads 1, and the cooling vane 3 of top utilizes screw rod 4 swivel nuts 5 structures to be connected with the cooling vane 2 of below, and screw rod 4 stretches out the adjustable length of swivel nut 5, and the vertical range about making between two cooling vanes is adjustable.
Up and down the air inlet of two cooling vanes respectively separate connection one typhoon machine is arranged.
The foregoing description in process of production, after film bubble 6 was extruded by die head 1, two cooling vanes 2,3 made film steep 6 cooling formings respectively to the blowing of film bubble up and down.
In the foregoing description, each cooling vane can be provided with two ring-type air outlets, also a ring-type air outlet can only be set.
Claims (5)
1, a kind of plastic membrane blowing equipment, comprise pressurizing unit, die head, collapser, wrap-up, it is characterized in that: be provided with two cooling vanes up and down above die head, two cooling vanes all are positioned at below the condensate line, and the ring-type air outlet of two cooling vanes is all towards the top.
