Description
Technical field
The present invention relates to the manufacturing and processing equipments of plastic film, and in particular to one kind in production thin-film process for being used to give
The vane cooler of film cooling.
Background technique
In the production process of plastic film, need to just being cooled down from the plastics membrane tube that head is drawn, so that plastics
The temperature of membrane tube is reduced and is formed, and is carried out cooling device to plastics membrane tube and is known as vane, currently, common vane by being divided on
Under two-part vane body and vane lid rent at, and be threadedly coupled, rotary wind ring cowling can change the gap of air outlet,
Use air volume change.Air inlet there are three setting up on vane body, compressed air is from air inlet along vane tangential direction
Enter simultaneously, vane body and vane lid are both provided with baffle plate, and the air of feeding is allowed to be buffered and be gradually reduced, and guarantee from out
The air of air port blowout has more stable and uniform wind pressure and air quantity, keeps the cooling velocity of each point on membrane tube circumference consistent, with
Guarantee that film thickness is uniform.
Since the air compartment of this vane is less, disengaging air quantity it is also less, cooling efficiency is lower, especially workshop temperature compared with
Gao Shi, cooling efficiency is lower, to guarantee cooling efficiency, it is necessary to freezing equipment additionally be arranged, cool down to cooling wind, to mention
High cooling efficiency, this not only increases the purchase commodity of equipment, and also increases the processing cost of film.
Summary of the invention
To solve the above problems, the cooler can not increase freezing equipment the invention proposes a kind of cooler
In the case of, guarantee to avoid the increase of film production cost, the specific technical solution of the present invention is as follows to the cooling efficiency of film cylinder:

Medial surface bottom, the wind for enabling the second air outlet to be discharged at once to from molding die outlet discharge the modern designs of plastics pipe
It being cooled down, the first air outlet continues to cool down the modern designs of plastics pipe on the basis of the second air outlet is cooling to the modern designs of plastics pipe,
The setting of double air outlets can carry out secondary cooling to the modern designs of plastics pipe, avoid primary cooling in the prior art be unable to complete pair
When the cooling of the modern designs of plastics pipe, need additionally to carry out the problem of cooling just can guarantee cooling effect to cooling wind, the invention avoids
Cooled down using freezing equipment to cooling wind, avoids the raising of the processing cost of film.
Further, the outlet section includes first shell, the first cylinder and the second cylinder, and the first shell includes up and down
The three pieces of annular slabs and a cylinder of superposition, three pieces of annular slabs are followed successively by upper annular plate, middle annular slab and lower annular plate from the top down,
The outer peripheral surface of three pieces of annular slabs is seamlessly connected on the inner wall of cylinder；Second cylinder is located at the inside of the first cylinder, upper annular plate
Inner edge connect the bottom surface of first cylinder, the inner edge of middle annular slab is connected to the middle part of the lateral surface of the second cylinder,
First air outlet is formed between the medial surface of one cylinder and the lateral surface of the second cylinder；The bottom surface of second cylinder and lower annular
There is gap, which forms second air outlet between plate；Offered on the cylinder of cylinder first air inlet and
Second air inlet.
After setting split type for outlet section, the expense of processing and fabricating is advantageously reduced, utilizes the more cheap plate of price
The production of outlet section can be completed in material, and can carry out batch machining to all parts of outlet section, further decreases cooler
Cost of manufacture.
Further, the medial surface of the lower annular plate is rounded.It, can be with after the medial surface of lower annular plate is provided in round
The present invention is easily mounted on to the outlet end of molding die, and installs and seals between the present invention and the outlet end of molding die
Part is spread under the wind direction that the second air outlet is discharged with being effectively prevented from, and then influences the temperature of the outlet end of molding die, and
The modern designs of plastics pipe is influenced normally to produce.
Further, the inlet section is in horizontally disposed ring-type, the rectangular in cross-section tubulose of the ring body of inlet section, the master
Air inlet is arranged on the downside of inlet section.After setting rectangular tubular for inlet section, both can using existing channel steel or
Rectangular tube makes after being bent, and can also be welded using plate.The downside of inlet section is arranged in main air inlet
On, the outlet of blower is attached with main air inlet with can be convenient.
