Description
Technical field
Blowing device technical field is the utility model is related to, specially a kind of blown film blowing device.
Background technology
Plastic sheeting is processed into frequently with the method for injection machine blown film in system moulds industry, the processing technology is by plastic pellet
After sub- heating and melting again blow out film, this film can be widely applied to weight packaging, have fresh keeping property it is good, it is moistureproof, freeze proof,
The advantages that oil resistant, but often there is rough, became uneven in film made of injection machine blown film device of the prior art
The quality problems such as even, the fragile easily broken, holes of poor flexibility, the blowing mouth of blown film device of the prior art is less, and blowing is uneven,
Cause the film bubble of blowout rough, in uneven thickness, while film bubble is blown in forming process in die head by tubulose, if cooling
Effect is poor, necessarily causes film bubble the problems such as poor flexibility, holes occur, greatly reduces final product quality, adds financial cost.
Utility model content
For blowing is uneven, cooling effect is poor, final product quality is low existing for blown film blowing device of the prior art, warp
The problems such as cost of helping is high, the utility model provides a kind of blown film blowing device, and its device is reasonable in design, and blowing is uniform, blowout
Film bubble it is uniform, smooth, and the device has good cooling effect, is greatly improved final product quality, reduces financial cost.
A kind of blown film blowing device, it includes die head, blowing ring, blast pipe, backwind tube, it is characterised in that it also includes
Cooling vane, low-temperature receiver is provided with the cooling vane, passes through the blast pipe between the cooling vane and the blowing ring
Connection, the air outlet of the cooling vane are opened on the inner side of the film outlet port of the die head；The backwind tube passes through the die head
Core rod after its one end connects with the cooling vane, the other end stretches out from the film outlet port of the die head.
It is further characterized by, and the blast pipe is provided with 6 to 8；
The die head is provided with below the cooling vane, the film outlet port of the die head is arranged on the upper of cooling vane
Side；
The blowing ring connecting fan；
The film outlet port side wall of the die head is provided with circular radiating hole in one week.
The utility model is used in blown film processing, the setting for ring of drying and the increase of blast pipe make the wind of blowout more equal
Even, raw material cools down through cooling vane and blows out shaping, and the film bubble of blowout further speeds up cold through the circular radiating hole at film outlet port
But, so as to ensure that film outlet port blowout film bubble surface is smooth, thickness is uniform, substantially increase product quality, and reduce through
Ji cost.
Brief description of the drawings
Fig. 1 is schematic device of the present utility model；
Fig. 2 is top view illustration of the present utility model（Omit blower fan）；
Fig. 3 is die head, film outlet port, the air outlet of cooling vane, the position view of backwind tube in Fig. 1.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of blown film blowing device, it includes die head 1, blowing ring 2, blast pipe 3, backwind tube
4, blast pipe 3 is provided with 6 to 8, and it also includes cooling vane 7, and low-temperature receiver, cooling vane 7 and blowing are provided with cooling vane 7
Connected between ring 2 by blast pipe 3, the lower section of cooling vane 7 is provided with die head 1, and the film outlet port 5 of die head 1 is arranged on cooling wind
The top of ring 7, the air outlet 10 of cooling vane 7 are opened on the inner side of the film outlet port 5 of die head 1, and 5 side wall of film outlet port is provided with for one week
Circular radiating hole 9, backwind tube 4 connects through its one end after the core rod of die head 1 with cooling vane 7, the other end is from the membrane of die head 1
Mouth 5 stretches out, the connecting fan 8 of ring 2 of drying.
Its operation principle is as described below, and the utility model is used in blown film processing, and wind is delivered to blowing ring 2 by blower fan 8
Interior, the wind dried in ring 2 is entered in cooling vane 7 by blast pipe 3, and raw material enters in die head 1 to be extruded after heated thawing
Into in cooling vane 7, it is blown into the wind of cooling vane 7 raw material after thawing is cooled down and blown out and blown out through film outlet port 5 after shaping,
Circular radiating hole 9 at film outlet port 5 further speeds up film bubble 6 and cooled down, so as to ensure that the surface light of film bubble 6 of the blowout of film outlet port 5
Cunning, thickness are uniform, and the wind in film bubble 6 is most discharged through discharge pipe 4 afterwards.
