Abstract
The utility model discloses a step type multi-purpose cooling wind-tubing for the production of the blown moulding plastic film, and the utility model is applied to the cooling process in the production of the tubular blown moulding plastic film. The wind-tubing adopts a blower and a set of blower tubes to complete wind blowing for more than two multi-step wind chambers, and the cold wind blows to the position in which the thin film is required to cool from more than two wind outlets with constant pressure and constant quantity and constant velocity. The wind-tubing can blow a plurality of tubular thin films with different folding paths on the same machine set and mould. The instance of the production indicates that the wind-tubing is positioned at the range of which the blow-up ratio is smaller than 5, and the mould is not replaced to produce the tubular thin films with a plurality of specifications stably. Compared with the common wind-tubing with a single wind port, the production capacity of the machine set is enhanced 60%, and the thickness common difference of the thin film is reduced 20%. In particular the wind-tubing is suitable for the fields of the production of the agricultural thin film, the large shed film, the packaging film, the composite thin film, etc., which are produced by the blow moulding method.
Description
The utility model is to use cooling vane about the ladder type in the inflation film production more, is applied to the cooling procedure in the tubular blown film production.This vane adopts the above ladder type cooling air compartment of a typhoon machine, one group of ajutage and second order, and from a plurality of air outlet level pressure, quantitatively, constant speed blow to the position that the film bubble needs cooling, realization is to the abundant cooling of all kinds of inflation films with cold wind.
In tubular blown film is produced, dispose suitable cooling vane, can improve the condition of molding of inflation film.Existing various cooling vane all adopts structures such as single air compartment list air port, the two air ports of single air compartment and the two air ports of double-wind chamber, and its air outlet is all below three.The specificity of these vanes is stronger, and common one pair of vane can only be blown the folding footpath and be changed little tubular film on same unit and mould.
The utility model provides a kind of ladder type to use cooling vane more.The cooling air quantity of this vane, cooling air band and cooled region can be according to the specifications vary flexible modulation of film.
Concrete solution is: the air compartment more than two is arranged to staged, and adopt a typhoon machine and one group of ajutage that runs through a plurality of air compartments, branch air port on ajutage is assigned to each air compartment with cold wind, each air compartment has an air outlet that the air-out angle is certain, the air output of each air compartment is controlled by the opening amount that adjusts the air port, all is provided with voltage stabilizing dykes and dams plate in the air compartment.
Compared with prior art, how ladder type can by regulating the use number and the air output of ladder air compartment air outlet, satisfy various special cooling requirements with cooling vane when producing the film of different size.Make one pair of vane can on same unit and mould, blow the tubular film of multiple folding footpath and varied in thickness.Production instance shows: use when three stageds are many blows the LDPE tubular film with cooling vane, because three air outlets that the air-out angle is different are arranged, cooling zone field width, adjustable range are big, blow-up ratio less than 5 scope in, use same pair of mould to produce the tubular film of plurality of specifications.The result who uses with the contrast of single air compartment list air port vane shows that the production capacity of unit has improved 60%, and the film thickness tolerance has reduced 20%.This vane is specially adapted to production fields such as agricultural film, awning film, packaging film and laminated film.
Accompanying drawing has been described an embodiment of the present utility model.
(1) tubular blown film;
(2) air outlet;
(3) voltage stabilizing dykes and dams plate;
(4) air compartment;
(5) ajutage;
(6) pole;
(7) divide the air port;
(8) blowing head;
(9) air-filled pore;
(10) blower fan;
(11) corrugated flexible hose;
(12) steady wind device.
Claims (2)
1, how the ladder type that is used for tubular blown film production cooling procedure mainly is made up of blower fan, air compartment, ajutage and air outlet with the cooling vane device.It is characterized in that: the air compartment more than two is arranged to staged.The ajutage that has a plurality of minutes air ports connects each air compartment, and multistage air compartment is only used a typhoon machine air feed.
2, use cooling vane according to the ladder type of claim 1 more, it is characterized in that: it is certain that every rank air compartment all has an air-out angle, and the adjustable air outlet of opening amount is provided with voltage stabilizing dykes and dams plate in the air compartment.
