Description
Technical field
The utility model belongs to the blown film apparatus technology, is specifically related to a kind of cooling water loop device of bottom blowing type inflation film manufacturing machine.
Background technology
Existing bottom blowing type inflation film manufacturing machine is provided with one deck cooling water ring, and this layer cooling water is equipped with the inwall of annular, the internal diameter of inwall than the big 6mm of vesicle diameter about, the inwall periphery is formed with the water storage cavity of annular, water storage cavity is provided with water inlet.During work, the film bubble passes from the annular inner wall centre and is constantly descending, and the water in the water storage cavity covers the upper edge of inwall, steeps the water curtain that peripheral shape circularizes at film, thereby can steep cooling off by film.Said structure can be satisfied the demand under the situation of speed of production low (being that film bubble extruded velocity is lower).But if speed of production improves, film bubble extruded velocity is accelerated; Need to improve cooling velocity to the film bubble; Cooling water inflow just must correspondingly and then strengthen, and the water curtain weight of steeping perimeter surface attached to film will increase, and current also strengthen the downward scouring force of film bubble; Film bubble under the scouring force three acting in conjunction under own wt, the water curtain weight of adhering to, the current direction, the tenesmus that is very easy to cause, drawn, problem such as distortion.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and cooling water loop device that a kind of bottom blowing type inflation film manufacturing machine is provided, and it can improve the cooling velocity to the film bubble, and prevents film bubble tenesmus distortion.
Its purpose can realize by following scheme: the cooling water loop device of this bottom blowing type inflation film manufacturing machine comprises the cooling water ring, and last cooling water is equipped with the last inwall of annular, and last inwall periphery is formed with the water storage cavity of annular; Water storage cavity is provided with water inlet; Its main feature is, on cool off the water ring below and also be provided with down the cooling water ring, following cooling water ring comprises the following inwall and the annular following outer wall of annular; Inwall and annular are formed with toroidal cavity between the outer wall down under the annular; Top at this toroidal cavity is provided with annular roof plate, is provided with annular bottom plate in the bottom of toroidal cavity, and toroidal cavity is provided with and is communicated with outside pump orifice; The big up and small down tapering of inwall under the annular, the annular upper edge diameter of inwall down equals the annular lower edge diameter of going up inwall, and the central axis of annular upward inwall is overlapping with the central axis of annular inwall down; The annular down wall body of inwall is a double-decker, and its ectomesoderm is the metal guard, and internal layer is the elasticity cylindrical body with a plurality of apertures, the elasticity cylindrical body metal guard that reclining.
Be preferably, the annular roof plate while of following cooling water ring toroidal cavity is as the diapire of annular water storage cavity.
The upper edge diameter of inwall is than the big 4～9mm of lower edge diameter under the annular.
The metal guard is the stainless steel guard.
The annular wall body internal layer of inwall down is the rubber mass cylindrical body with a plurality of apertures.
Above-mentioned going up cooled off the cooling water ring that water ring is equivalent to existing bottom blowing type inflation film manufacturing machine.
The utlity model has following advantage and effect:
When 1, the utility model used, pump orifice connected the negative pressure suction pump.In the process of blow moulding machine blown film, inwall lower edge diameter is identical down with annular for vesicle diameter; The water that last cooling water ring overflows circularizes water curtain in the peripheral shape of film bubble, and the annular water curtain annular of flowing through goes up the gap between inwall and the film bubble, and continues trickling downwards, flows into annular inwall and the film gap of steeping down; The toroidal cavity that cools off water ring down forms the space of a relative closure under the surrounding of outer wall under horizontal annular base plate, horizontal annular top board, annular water curtain and film bubble, the annular.The suction pump that pump orifice connects is constantly taken the water of annular water curtain, the air that leaks into away, and toroidal cavity forms and remain negative pressure space; Like this, can prevent film bubble tenesmus problem from three aspects: first aspect, toroidal cavity keep the certain negative pressure degree always, and film bubble the inside air pressure is bigger than outer surface pressure, and the film bubble just touch elastomer, can alleviate the tenesmus that the weight of film bubble own causes greatly; Second aspect, the current on film bubble surface are constantly taken away from elastomeric aperture, water curtain can not gathered in a large number, for a long time and attached on the film bubble surface, can alleviate the tenesmus that current weight causes greatly; The third aspect, elastomer can reduce degradation degree under the current direction, alleviates the tenesmus that scouring force causes under the current direction.Because above-mentioned three aspect factor, make the utility model can strengthen the cold water flow and can not cause and the tenesmus of film bubble can improve cooling velocity, and then can improve film bubble speed of production.
