The water cooling component 22 of side；The water cooling component 22 includes water tank 221, the tank 222 in closed hoop, connects the water tank 221
Water pipe 223 with the lateral wall 222a of the tank 222, the control valve 224 on the water pipe 223 and it is cylindrical in shape and upper end
It is connected to the madial wall 222b of the tank 222 cooling cloth 225；Wherein, the madial wall 222b of the tank 222 is less than described
The lateral wall 222a of tank 222；
Shaping mechanism 3, its two extruding deflector roll 32 for including two heating plates 31 of V-shaped arrangement and be arrangeding in parallel, two
The individual lower end of heating plate 31 is formed between the first gap 311, two extruding deflector rolls 32 and formed between the second gap 321, described first
Gap 311 is set in parallel in directly over the second gap 321；
Coiled body 4, it includes transition deflector roll 41 and the wind-up roll 42 being be arranged in parallel with the transition deflector roll 41.
During specific coextrusion mold, the tubular film 5 extruded by die head 11 is constantly moved downward, and is sent in air-cooled component 21
Secondary sizing is carried out into water cooling component 22 after the lower preliminary cooling and shaping of progress of gentle breeze effect, preliminary cooling and shaping, it is specific cold
But water is entered in tank 222 by water tank 221, and when the water in tank 222 is higher than the madial wall 222b of tank 222, it is by water
The madial wall 222b of groove 222 overflows and drenches the cooling cloth 225 on the madial wall 222b of tank 222, cooling cloth 225
Internal diameter may be configured as the external diameter slightly larger than tubular film 5 so that film 5 can contact drench cold during moving downward
But cloth 225, and then film 5 is cooled and shaped, the film 5 after shaping enters the second gap 321, this reality through the first gap 311
Apply the settable thickness being folded into after plane film 5 with tubular film 5 in the second gap of example 321 mutually to agree with, in order to by its roller
Molded, the film 5 after roll-in, which can bypass, has wind-up roll 42 to wind after transition deflector roll 41.Wherein, two heating plates of the present embodiment
31 are set to V-type, and two faces of itself and the film 5 before the roll-in slabbing of film 5 are mutually agreed with, in order to the washmarking on film 5
Dried, the temperature of heating plate 31 is unsuitable too high, is advisable with not resulting in the softening transform of film 5.
Wherein, control valve 224 is preferably arranged to flow valve, its cooling current direction tank that can be used in control water tank 221
222 flow, and then the spilling speed of cooling water in tank 222 is controlled to control the moist degree of cooling cloth 225, so as to reach
Control cooling cloth 225 cools down the efficiency of film 5.
Water cooling component 22 described in the present embodiment also includes the absorption being coaxially covered on the madial wall 222b of the tank 222
Layer 226, cooling cloth 225 upper end is connected to the inwall of the adsorption layer 226, and tank can be adsorbed in real time by adsorption layer 226
222 cooling waters overflowed, its cooling water adsorbed can be moved downward along cooling cloth 225 makes cooling cloth 225 be in dampness, and sets
Appropriate cooling water can be stored by putting adsorption layer 226, and it can adjust the dampness that cooling cloth 225 is in a certain degree, it is to avoid overflow
The cooling water gone out, which is flowed directly on cooling cloth 225, to be caused cooling dilutional hyponatremia on cooling cloth 225 and its lower end is dripped.Moreover, adopting
Being homogenized after being conducive to the cooling for overflowing tank 222 with adsorption layer 226, and then ensure that cooling cloth 225 is circumferential has phase
Same wetness, and then the harmony for promoting film 5 to cool down.Specifically, adsorption layer 226 described in the present embodiment is preferably sponge material
Matter, cooling water and uniform is dispersed on cooling cloth 225 by it compared with the absorption cooling water of limits.
Air-cooled component 21 described in the present embodiment include bellows 211 annular in shape and with the annular housing in the bellows 211
The cooling blower 212 of 211a connections；The multiple and annular housing 211a has been evenly arranged in the inside side walls of bellows 211 to connect
Logical air vent 211b, when specifically acting on, the driving gas stream of cooling blower 212 enters annular housing 211a, and passes through air vent
211b is formed carries out air-cooled air-flow to the outer peripheral face of tubular film 5.Wherein, in order to improve multiple air vent 211b air-flow
Multiple airducts 213 are can be set in harmony, the present embodiment, and the outlet air end of multiple airducts 213 is connected with annular housing 211a, and many
The outlet air end of individual airduct 213 is arranged circumferentially along the bellows 211.
Unformed film 5 is caused to deform in order to avoid the cooling wind discharged by air vent 211b is excessive, the present embodiment
The air vent 211b is tapered, and its aperture gradually increases along the airflow direction in the air vent 211b, passes through its aperture
Gradually increase, so that air-flow be disperseed and small air-flow is formed, and then be easy to the tentatively sizing of film 5.
Compared with prior art, the utility model is cooled down to film successively by air-cooled component and water cooling component, its
Middle water cooling component makes cooling cloth be in moist device to cool down film by the way that cooling water is overflowed by the madial wall of tank
Shaping, it advantageously ensures that cooling effect, it also avoid forming water stain on film, and right respectively using V-shaped heating plate
