Abstract

The utility model discloses a film cooling device of a film blowing machine, which is provided with a blower. The blower is assembled with a wind ring. The film cooling device is characterized in that: the film cooling device further comprises an inner cooling system; the inner cooling system is composed of a cold water machine, a radiator and a cold wind pipe; the cold water machine is connected with the radiator by a pipeline, the blower is matched with the radiator, the cold wind pipe comprises a wind inlet cold pipe and a wind exhaust hot pipe, and the wind exhaust hot pipe is assembled with an exhaust blower. The film cooling device is designed into the structure with inner and outer cooling at the same time, and the inner cooling system can carry out circulation, so that the internal temperature of a film can be kept stable, thereby achieving the purpose of controlling the film blowing thickness; moreover, an ultrasonic wave sensor can monitor the diameter of a film bubble in real time, and can automatically adjust the wind inlet and exhaust volume at any time, so as to lead gases in the film bubble to reach a balance state; therefore, the cooling effect is obvious, the output is increased, the transparency is enhanced, and the thickness of the film is ensured as well.

Description

A kind of film cooling device of inflation film manufacturing machine

Technical field:

The utility model relates to a kind of improvement invention of inflation film manufacturing machine film cooling device, what be specifically related to is a kind of hydronic inflation film manufacturing machine film cooling device that carries out.

Background technology:

Inflation film manufacturing machine cooling device of the prior art is to adopt high pressure positive blower to blow into the external cooling vane to carry out the film external refrigeration, and its weak point is that cooling effect is not obvious, output is proposed not high, the difficult control of film thickness and film clarity is bad.

Summary of the invention:

Given this, the technical problem that the utility model solved is for a kind of good cooling results is provided, can obviously improve output and film thickness can be controlled in positive and negative 4 millimeters with interior film cooling device.In order to achieve the above object, the utility model adopts following technical scheme to realize: the film cooling device of this kind inflation film manufacturing machine, has blower fan, described blower fan is fitted with vane, it is characterized in that described film cooling device also includes an internal cooling system, this internal cooling system is by cooling-water machine, radiator, cool air hose is formed, cooling-water machine is connected with radiator by pipeline, blower fan matches with radiator, described cool air hose includes blast pipe and exhaust duct, exhaust duct is fitted with exhaust blower, and outer cooling system then is that the wind air supplying ring of outer air-cooler is used for to the film external refrigeration and plays styling.

Described film cooling device is fitted with ultrasonic sensor.

The utility model is owing to the structure of cooling off simultaneously inside and outside the film cooling device is set to, and internal cooling system can circulate, make the film internal temperature keep stable with this, and can reach the purpose of blown film controllable thickness system, and ultrasonic sensor is monitored vesicle diameter in real time, at any time regulate intake and exhaust air rate automatically, thereby make the gas in the film bubble reach a kind of poised state, not only cooling effect is obvious, and output has improved, transparency has also increased, and guarantees film thickness simultaneously.

Description of drawings:

The utility model has following accompanying drawing:

Fig. 1 the utility model structural representation;

Fig. 2 is the utility model cooling system structure schematic diagram.

The specific embodiment:

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing is only for reference and explanation, is not to be used for the utility model is limited.

As shown in Figure 1, the utility model is by two high pressure positive blowers, cooling-water machine 6, radiator 7, external cooling vane 2, internal cooling system is formed, the wind of outer air-cooler blows into external cooling vane 2, be used for to the film external refrigeration, film bubble 5 is played support and cooling and styling, in the cold water inflow radiator of cooling-water machine, the wind of a high pressure positive blower blows into radiator, the cold wind that comes out enters in the film bubble through three passages under the die head, inwall to the film bubble cools off, other three air exhaust passages are discharged hot gas under the effect of another air draft blower fan simultaneously, and ultrasonic sensor 3 is the monitoring vesicle diameter in real time, regulates intake and exhaust air rate at any time automatically, thereby make the gas in the film bubble reach a kind of poised state, guarantee film thickness.

During the utility model work, in cold be to enter into radiator 7 by the recirculated water that cooling-water machine 6 provides, the wind that interior cold anticyclone blower fan 8 blows out forms cold wind behind radiator 7, A by film head 1 below, B, three air inlets of C enter in the film bubble 5, inwall to film bubble 5 cools off, thermal current in the film bubble 5 is by behind the blast pipe 4 simultaneously, pass through the exhaust passage D in the die head 1 again, E, F, under the effect of exhaust blower 9, thermal current is discharged at last, form heat exchange, and intake and exhaust air rate are to steep four ultrasonic sensors on 5 peripheries and monitor the diameter of film bubble in real time and control intake and exhaust air rate for signal feedback high pressure positive blower 8 and air draft blower fan 9 by being installed in film, thereby make the gas in the film bubble reach a kind of poised state.

But the above only is a preferable possible embodiments of the present utility model, is not in order to limiting to claim of the present utility model, and the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all in like manner is included in the scope of the present utility model.
