Description
Technical field
The present invention relates to inflation film manufacturing machine technical equipment fields, and in particular to a kind of inflation film manufacturing machine film bubble quickly cooling cover.
Background technique
Squeezing out upper blowing method inflation film moulding process is the film forming technique that current thin film manufacturing enterprise largely uses.This
The advantages of kind technique is that bubble tube shape is stablized, and occupied area is small, and folding diameter easy to produce is big, the big film of thickness；The disadvantage is that seek survival
It produces workshop and chooses higher, be not suitable for the small particle of viscosity, be unfavorable for the cooling of film.The cooling of upper blowing method inflation film is blow molding
The key link of membrane system, the cooling effect of film bubble directly influence film yield and quality.During extrusion-blown modling
It need to guarantee that film bubble is stable, does not shake, cooling surrounding is cooling uniformly in time, can just produce thickness, all qualified thin such as width
Film, and film has good physical and mechanical property.The unstable fluctuation that will cause film thickness and width of extrusion blown film film bubble,
The problems such as scratch and tearing.Thus it is guaranteed that inflation film workshop interior air-flow is stablized, temperature is stablized, for squeezing out upper blowing method
The production of film, it is particularly important.
In inflation film actual production, some enterprises usually use common Workshop Production blown film to save cost,
In workshop not can the steady steady temperature of air-flow central air conditioner system, or there is air-conditioning system to be but reluctant to being switched on, if encountered
High temperature season produces blown film, it is necessary to which cooling system is more powerful, and in the small range around film bubble, it is steady to create air-flow
It is fixed, the suitable subenvironment of temperature.
It is known that current upper blowing method inflation film manufacturing machine is typically all to use the cooling film bubble inner wall of internal cold wind wind column inflation,
Blown film steeps the outer wall type of cooling to external cold wind vane from lower to upper, be around film bubble it is open unobstructed, if there is crossflow,
The disturbance of film bubble will be directly contributed, the width and thickness of film is all inaccurate, influences film quality.If added outside film bubble
The current stabilization cover for blocking crossflow externally has radiation thermal conduction since film bubble self-temperature is higher, will stationary part in heating mantles
The air divided, increases case temperature, is unfavorable for film bubble cooling.In order to not only prevent crossflow, but also not influence film bubble cold
But, it is necessary to develop a kind of film bubble outer cover, should guarantee to cover film bubble surrounding, prevent crossflow, also to guarantee to cover interior temperature
It spends constant, does not influence film bubble heat loss through radiation around.

Partition, the outer cover stent are set to the outside of the interior cover stent, and the central axis of the outer cover stent and the blown film
The central axis of machine die head is overlapped, and is uniformly provided with the cover glass partition, the cold wind on the circumferential surface of the outer cover stent
Pipe is set between the interior cover stent and the outer cover stent, and the cool air hose bends to quadrangle form, described cold
Air hose it is closed at one end, the other end connect with external air-cooler, and direction downwards described is designed in the cool air hose each edge
Air outlet, the air outlet are equipped with the manually-operated gate.
Further, the cool air hose is bent in each edge of quadrangle form at least provided with two air outlets.
Further, the cross section of the interior cover stent is octagon.
Further, the cross section of the outer cover stent is square.
(3) beneficial effect
The present invention provides a kind of inflation film manufacturing machine film bubble quickly cooling cover, and cool air hose is equipped between inside and outside cover, can keep between inside and outside cover
Be full of Cryogenic air in gap, thereby reduce inner cover temperature, envelope temperature and between them clearance air temperature, film bubble
Due to being mounted with inside and outside cover, crossflow can not interfere film bubble for outside, be full of Cryogenic air always between inside and outside cover, film bubble
Radiant heat energy is constantly taken away by cold air, and the heat loss through radiation efficiency of film bubble improves, and further improves the cooling efficiency of film bubble.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
