Industry；Gather cruel film and polyamide film and be mainly used as insulating materials and packaging material.
In the preparation method of thermoplastic film by thermoplastic resin high temperature melt after, by chill roll carry out cooling and shaping, prevent
Contract on cooling influences final product quality after winding, and existing chill roll is substantially by the way of water cooling, and cooling water is from chill roll
One end flows to the other end, and in this course, and the temperature of cooling water constantly raises, so that the temperature of cooling roller surface is along cold
But water flows into end and is constantly raised to the direction that cooling water flow out of end, causes the inhomogeneous cooling to thermoplastic film even, when being wound
Influence its final product quality.
Utility model content
The utility model is intended to provide a kind of chill roll, to solve even to thermoplastic film inhomogeneous cooling in the prior art ask
Topic.
A kind of chill roll, including deflector roll, deflector roll are internally provided with cavity, and one end of deflector roll is connected with first flange, deflector roll
Another section be connected with second flange, clutch shaft bearing is fixedly installed in first flange, second is fixedly installed in second flange
Bearing, is equipped with multiple annular cooling tubes, cooling tube and deflector roll coaxial line in cavity successively, the outer wall of cooling tube and deflector roll it is interior
Wall fits closely, and the tube wall of cooling tube is equipped with water inlet and water outlet, and water inlet and water outlet are symmetrical arranged, are equipped with cavity
With the water inlet pipe and outlet pipe of deflector roll coaxial line, the first connecting tube, water outlet and water outlet are communicated between water inlet and water inlet pipe
The second connecting tube, water inlet pipe and clutch shaft bearing rotation connection, outlet pipe and second bearing rotation connection are communicated between pipe.
The operation principle of the utility model：When being cooled down to thermoplastic film, it is fixed that thermoplastic film by chill roll cool down
Type, in the heat transfer of thermoplastic film to deflector roll, the water in water inlet pipe is cold by being flowed into annular after the first connecting tube and water inlet
But in pipe, the outer wall of cooling water pipe and the inner wall of deflector roll fit closely, and the heat heat transfer on deflector roll is into cooling water, cooling water
By being flowed into outlet pipe after water outlet and the second connecting tube after absorption heat, so during water circulates, multiple annulars
Cooling tube is cooling down deflector roll, because water inlet and water outlet are symmetrical arranged, water is flowed into annular cooling by water inlet
Pipe, then flowed out from water outlet, by making water inlet and water outlet to being symmetrical arranged, cooling path of the water in cooling tube is maximum,
Whole cooling tube can be cooled down, beneficial to the cooling of deflector roll, while in the maintenance in later stage, by dismantling deflector roll both ends
Flange, can take out cooling tube, beneficial to the maintenance in later stage.
The beneficial effects of the utility model：During cooling down to deflector roll, multiple annular cooling conduits are respectively to it
The region being bonded with deflector roll cools down, and annular cooling conduit is constantly intake and water outlet, and water is in annular cooling conduit by once following
Just flowed out after ring from outlet pipe, circulating path is short, and water inlet pipe and outlet pipe are separate in temperature-fall period, so just make
The surface cooling of deflector roll is uniform, beneficial to the shaping of thermoplastic film, by dismantling the flange at deflector roll both ends, can take cooling tube
Go out, beneficial to the maintenance in later stage.
Further, the surface of the outlet pipe is equipped with thermal insulation layer.Water heats up after one cycle and is flowed into outlet pipe,
In order to avoid outlet pipe Water transport heat in water inlet pipe, by setting thermal insulation layer on the surface of outlet pipe, slow down the biography of heat
Pass.
Further, the surface of the cooling tube is equipped with wearing layer.Chill roll is when rotating, the outer wall of its inner wall and cooling tube
Rub, by setting wearing layer to improve the service life of cooling tube.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of chill roll of the utility model.
