Abstract

The utility model discloses a film bubble closed type cooling water ring which comprises a water inlet pipe and a water return pipe and is characterized in that the upper end of the water inlet pipe is communicated with the bottom end of an inner cavity of a dual-layer sealed ring sleeve, the upper end of the water return pipe is communicated with the upper end of the inner cavity of the dual-layer sealed ring sleeve, the lower end of the water inlet pipe is communicated with a water storage pond by a high pressure water pump, the lower end of the water return pipe is provided with a water spray pipe, and the water spray pipe is mounted on the upper side of the water storage pond through a bracket. In the film bubble closed type cooling water ring, water is circulated in a sealing manner and cannot directly act on the film bubble, therefore, the extruding quality of film blowing is improved under the sufficient cooling situation, furthermore, water is recycled, so the production cost of film bubbles is reduced, and the film bubble closed type cooling water ring is particularly applicable to the blow molding production of ultra-thick films.

Description

Film bubble closed cooling water ring

Technical field

The utility model relates to a kind of improvement of film bubble cooling water ring, specifically a kind of film bubble closed cooling water ring.Be applicable to inflation film manufacturing machine on the plastics.

Background technology

In plastic sheeting blowing was produced, the film bubble temperature that blows out was higher, just can batch after must cooling off.For the cooling of film bubble, blow a cold wind on the film bubble through vane mostly and cool off, but air-cooled effect is relatively poor at present.The employing water-cooling ring that also has cools off, and this water-cooling ring comprises upper and lower annular tank, and is excessive after the water in the last annular tank is full of, the water that overflows outward along the outer wall of film bubble to dirty, thereby make film bubble cooling cooling.The existing deficiency of this water-cooling ring is: when water flows on film bubble surface; Can not distribute uniformly, cause film bubble cooling velocity uneven, gauffer often appears in the film bubble; It particularly is the superthick film of 0.2-2mm for thickness; Occur gauffer more easily, influence the transparency and the quality of production, and cooling effect is also relatively poor; Because current back down evaporate and run off, thereby cause the waste of water, improved production cost.

Summary of the invention

The purpose of the utility model is to provide a kind of can improve extruding quality, preventing gauffer of film bubble; Thereby can make water circulation use reduce production costs, improve output again, be specially adapted to the film bubble closed cooling water ring that the blowing of superthick film is produced.

For reaching above purpose; The technical scheme that the utility model adopted is: this film bubble closed cooling water ring, comprise water inlet pipe and return pipe, and it is characterized in that: the upper end of water inlet pipe is connected with the inner chamber bottom of double-layer seal ring set; The upper end of return pipe is connected with the inner chamber upper end of double-layer seal ring set; Lower end at water inlet pipe is inserted in the tank through high-pressure hydraulic pump, is provided with sparge pipe in the lower end of return pipe, and sparge pipe is installed in the upside of tank through support.

The utility model is also implemented through following measure: described double-layer seal ring set is two-layer stainless steel cylinder, and the overall diameter of internal layer is 40-160mm, and wall thickness is 3mm, and outer field interior diameter is 56-176mm, and the end is provided with sealing ring; Be provided with slow water cavity in the bottom of double-layer seal ring set, water inlet pipe inserts in the slow water cavity.

The beneficial effect of the utility model is: with at present in blown film employed air-cooled or cold water ring compare; Because water is the sealing circulation, water does not directly act on the film bubble, so under the situation of fully cooling; Improved the quality of extruding of blown film; Can make water circulation use again, thereby reduce the production cost of film bubble, be specially adapted to the blowing production of superthick film.

Description of drawings

Fig. 1 is the structure cross-sectional schematic vertically of the utility model.

Among the figure: 1, water inlet pipe; 2, return pipe; 3, double-layer seal ring set; 4, high-pressure hydraulic pump; 5, sparge pipe; 6, support; 7, sealing ring; 8, slow water cavity.

The specific embodiment

Make the utility model with reference to Fig. 1.This film bubble closed cooling water ring; Comprise water inlet pipe 1 and return pipe 2; It is characterized in that: the upper end of water inlet pipe 1 is connected with the inner chamber bottom of double-layer seal ring set 3, and the upper end of return pipe 2 is connected with the inner chamber upper end of double-layer seal ring set 3, inserts in the tank through high-pressure hydraulic pump 4 in the lower end of water inlet pipe 1; Be provided with sparge pipe 5 in the lower end of return pipe 2, sparge pipe 5 is installed in the upside of tank through support 6.When using the utility model, double-layer seal ring set 3 is enclosed within the film bubble upward fixes, when high temperature membrane is steeped upwards blowing, start high-pressure hydraulic pump 4; Cold water in the tank is squeezed in the double-layer seal ring set 3, and water flows in double-layer seal ring set 3 from bottom to top, and carries out heat exchange with the high temperature membrane bubble; Make the cooling of film bubble, the water that absorbs heat flows out from return pipe 2, gets into sparge pipe 5; Make water for cooling through sparge pipe 5, get into tank, successively circulation.

As the improvement of the utility model, described double-layer seal ring set 3 is two-layer stainless steel cylinder, and the overall diameter of internal layer is 40-160mm, and wall thickness is 3mm, and outer field interior diameter is 56-176mm, and the end is provided with sealing ring 7; Be provided with slow water cavity 8 in the bottom of double-layer seal ring set 3, water inlet pipe 1 inserts in the slow water cavity 8, makes the water of water inlet pipe 1 be introduced into slow water cavity 8, makes the pressure of water reach consistent all around.
