Background

At present, in the known technology, the air ring on the plastic blow molding machine head is only processed with an air ring body with an annular mixed air channel, the upper part of the mixed air channel is provided with a sealing gland matched with the mixed air channel, and the air ring body at the inner side of the mixed air channel is radially provided with a whole circle of air outlets. When the blow molding machine starts to work, air blown in through the air inlet pipe connected with the air ring is mixed and equalized in the annular mixed air duct, and then cooling air is supplied to blow film bubbles through the whole circle of air outlet of the air ring. However, in the actual production process, the air output is not uniform because the structure cannot adjust the local air volume according to the longitudinal narrow range of the film, so that the thickness difference of the longitudinal narrow part of the film bubble is influenced, the thin point part of the film is aged prematurely, the lighting of the thick point part of the film is poor, and the heating rate is reduced. In addition, because of the precision deviation of the used die, the adjustment slight difference and the temperature deviation in the heating of the electric appliance, the temperature of the die is easy to be uneven, so that the quality of the product is difficult to ensure, and the production cost is increased.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to figures 1-4 of the drawings,

the cooling air ring capable of realizing fine adjustment of the film blowing machine comprises an annular air chamber 2, an upper sealing cover plate 8, a lower sealing cover plate 9, a first air adjusting ring 7, a second air adjusting ring 6 and a plurality of air inlet nozzles 1 which are arranged on the outer periphery of the annular air chamber and communicated with the annular air chamber. The upper sealing cover plate and the lower sealing cover plate are respectively fixedly connected with the inner ring of the annular air chamber, and an inner air duct 11 is formed among the annular air chamber, the upper sealing cover plate and the lower sealing cover plate. The first air adjusting ring is in threaded connection with the upper sealing cover plate, and the second air adjusting ring is located below the first air adjusting ring and in threaded connection with the lower sealing cover plate. And a gap is formed between the first air adjusting ring 7 and the second air adjusting ring 6 to form an upper air channel 5 communicated with the inner air channel 11, and the upper air channel is communicated with the inner cavity of the first air adjusting ring through an upper air channel outlet 12. This cooling wind ring accessible screw thread adjusts first air register and upper seal apron, and then adjusts the size of wind channel 5 on. A plurality of lower air duct through holes 14 are uniformly distributed in the lower sealing cover plate, a lower air duct sealing cover plate 15 is arranged at the joint of the bottom of the lower sealing cover plate and the second air regulating ring, a lower air duct 13 and a lower air duct outlet 10 which are communicated with the inner cavity of the second air regulating ring are arranged between the lower air duct sealing cover plate and the lower sealing cover plate as well as between the lower air duct sealing cover plate and the second air regulating ring, and the lower air duct is communicated with the lower air duct through holes 14. And the upper sealing cover plate is positioned on the outer circumferential ring of the first air adjusting ring and is provided with a plurality of adjusting mechanisms for longitudinally fine adjusting the film.

Specifically, the adjusting mechanism comprises a fine adjustment bolt 4 and a fine adjustment nut 3, and the fine adjustment bolt 4 penetrates through the upper sealing cover plate.

Specifically, the distance between two adjacent adjusting mechanisms is 15-25 mm.

Specifically, the distance between two adjacent lower air duct through holes 14 on the lower air duct is 10 mm.

The working principle of the invention is as follows:

when the blow molding machine starts to work, the fan respectively enters the annular air chamber 2 from the air inlet nozzle 1, the air is mixed and equalized in the annular air chamber, enters the first air adjusting ring 7 through the inner air duct 11 and the upper air duct 5, enters the second air adjusting ring 6 through the inner air duct 11 and the lower air duct 13, and is blown out through the first air adjusting ring and the second air adjusting ring to blow film bubbles. When the product quality is affected by the fact that a certain longitudinal position of a film bubble blown out from a machine head is too thick or too thin, the fine tuning bolt 4 and the fine tuning nut 3 can be adjusted to enable the fine tuning bolt 4 to penetrate through the upper sealing cover plate to move up or down, and the air quantity of the corresponding position of the inner air duct 11 is adjusted. When a certain part of the film bubble in the longitudinal direction is too thick, the fine adjustment bolt 4 can be loosened and fine adjusted downwards, so that the air volume passing through the part is slightly reduced; when a certain part of the film bubble in the longitudinal direction is too thin, the fine adjustment bolt 4 can be loosened and fine adjusted upwards, so that the air volume passing through the part is slightly increased; therefore, the air output of the part is kept balanced with the air output of other parts, so that the thickness of the film bubble at the part is ensured, and the quality stability is realized.

The embodiments of the invention that are illustrated in the drawings are exemplary only and should not be taken as limiting the invention.
