Description
Technical Field
The invention relates to the field of plastic film production, in particular to a wind ring device for blow molding.
Background
With the progress of human science and technology, plastic films are used as packages to replace most of paper packages, the demand of the films is huge, and the films can be formed by a flat extrusion up-blowing method.
The wind ring device in current production generally adopts single wind gap wind ring device, but the cooling efficiency who adopts single wind gap wind ring device is lower, chinese utility model patent that bulletin number is CN206884159U among the prior art has announced a two wind gap wind rings of degradation inflation film manufacturing machine, wind ring device in this patent has two air outlets, the area of contact of the cold air that two air outlets blown off and film pipe is bigger, so cooling efficiency is higher, two air outlets blow to the film pipe from different positions simultaneously and make the cooling of film pipe more even.
Although the technical scheme in the patent solves the problem of low cooling efficiency, the technical scheme still has the following problems:
first, in the actual production, often need produce the film pipe of different diameters according to the demand of difference, and the film pipe of different diameters blows off the requirement of angle and is different to the cold air, and two air outlets are all fixed among this technical scheme, so the angle that the cold air blew off is fixed all the time, can't satisfy under the different diameters film pipe to the different demands that blow off the angle of cold air.
Second, the air outlet position is in open state for a long time, and the dust enters into the inside of wind ring device through the air outlet easily, accumulates for a long time that the dust inside wind ring device can be driven by the cold air and blow to the film pipe, on the one hand, writes to be done away and makes to be stained with the dust on the film pipe, on the other hand, the existence of dust can influence the homogeneity that the cold air blew out, and then causes the film pipe cooling inhomogeneous, is unfavorable for the promotion of film quality.
Thirdly, the indoor and outdoor temperatures in summer of China are higher, the cooling air required by cooling the film tube is more, and the indoor and outdoor temperatures in winter are lower, the cooling air required by cooling the film tube is less; therefore under the different ambient temperature, the required cold air amount of wind of film pipe cooling is different, but this technical scheme's cold air blows off the back from the air outlet, and the cold air is on the one hand through the louvre effluvium, continues to blow on the film pipe on the one hand and cools down, because of the unable adjustment of louvre size for the amount of wind of the cold air that blows on the film pipe accounts for than being fixed, therefore can't satisfy under the different ambient temperature to the cold air amount of wind demand of blowing to the film pipe.
Disclosure of Invention
The invention aims to provide an air ring device for blow molding, and aims to solve the problems that the angle of cold air blown out from an air outlet cannot be adjusted and dust is accumulated in the air ring in the prior art.
In order to achieve the above object, the basic scheme of the invention is as follows: the air ring device for blow molding comprises an air disk base and an upper air disk, wherein the upper air disk covers the air disk base, a lower air lip is fixedly connected to the upper air disk, an annular main air duct is formed among the air disk base, the upper air disk and the lower air lip, a lower air duct blowing towards a film tube is formed between the air disk base and the lower air lip, and the lower air duct is communicated with the annular main air duct; the lower air lip is provided with a plurality of upper air channels blowing to the thin film tube, the lower air lip is provided with an annular groove, the annular groove is provided with an opening, the annular groove is internally and slidably connected with an adjusting ring, the adjusting ring is provided with a through hole, and each upper air channel can be communicated with the annular main air channel through the through hole and the opening.
The working principle is as follows: when the blow molding machine does not work, the adjusting ring is slid, so that the through hole is not communicated with any upper air duct, and then the adjusting ring blocks the communication between all the upper air ducts and the annular main air duct, and dust is prevented from entering the annular main air duct through the upper air duct. When the blow molding machine works, a proper upper air channel can be selected to be communicated with the annular main air channel according to the production requirement of the film tube, and then cold air at a specific angle is blown out.
