Description
Technical field
The utility model relates to technical field of plastic, especially a kind of PVA inflation film manufacturing machine.
Background technology
Existing inflation film manufacturing machine is formed primarily of parts such as drive unit, main body, die head and vanes, plastic raw materials is heated to molten state by main body, then by the screw rod in machine, the plastics of molten state are pressed to die head, finally by vane, the plastics extruded from die head are cooled, current vane used is the hollow structure being connected with multiple blast pipe, wind enters vane from blast pipe and is blown out by the air outlet of vane inwall, thus realizes drying the object making it cool to film blowing machine tubular membrane.
Because existing vane is mainly cooled film by the velocity of liquid assets increasing air, when in summer, air themperature is higher, and the temperature of inside plants may be higher, but by weak effect that the air in suction environment cools the plastic foil that die head is extruded, have a strong impact on the quality of plastic foil, cause stretching uneven.
Utility model content
The technical problems to be solved in the utility model is: in order to solve existing inflation film manufacturing machine cooling vane when environment temperature is higher to the weak effect problem of film blowing machine tubular membrane cooling, the utility model provides a kind of PVA inflation film manufacturing machine, by the blast pipe cooling device at vane, effectively solve existing cooling air ring for film blowing machine when environment temperature is higher to film blowing machine tubular membrane cooling difference problem.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of PVA inflation film manufacturing machine, comprise drive unit, feed hopper, main body machine, screen pack mould body, die head, vane, folder and support, the outlet of die head is fixedly connected with vane, described vane comprises vane body, air intake passage and blast pipe, the madial wall of described vane body is provided with air outlet, the lateral wall of described vane body is provided with air inlet, described air intake passage outlet is communicated with air inlet, described air intake passage import is communicated with blast pipe, described blast pipe outer setting has the cooling device cooled the wind in blast pipe.
Further, described cooling device is the sleeve pipe be set in outside blast pipe, described sleeve pipe and blast pipe form the Inner cavity being used for cooling blast pipe, described sleeve pipe is arranged and the water inlet of Inner cavity connects and delivery port, water enters internal cavity from water inlet, and from the delivery port of internal cavity out, with the heat on blast pipe, reach the effect of cooling wind-warm syndrome.
Further, set temperature sensor on described air intake passage, detects cooled air themperature by temperature sensor, adjusts the flow velocity of water, ensures the stable of air themperature.
Particularly, described main body machine arranges attemperator, prevents the loss of heat, ensure that plastic grain can melt as early as possible.
The beneficial effects of the utility model are: a kind of PVA inflation film manufacturing machine that the utility model provides, simple to operate, easy to use, by cooling the blast pipe of vane, when environment temperature is too high, ensure the cooling effect to periosteum of vane, cooled air themperature is detected by temperature sensor, adjust the flow velocity of water, ensure the stable of air themperature, ensure when environment temperature is very high, vane is still very good to the cooling effect of periosteum, and ensure that quality, by arranging the loss that attemperator prevents temperature on main body machine, cause the heating of main body to plastics uneven.
