Specific embodiment
In order to it is clearer, completely illustrate the technical solution of the utility model, with reference to the accompanying drawing to the utility model
It is described further.
Please refer to Fig. 1 to Fig. 3, the utility model proposes chill roll include roller wall 2 and roll shaft 1；The roll shaft 1 includes position
In partition 11 helical on 1 surface of roll shaft, the partition 11 makes to form multiple spiral shells between the roller wall 2 and the roll shaft 1
Revolve channel 13.
In chill roll, there is gap between roll shaft 1 and roller wall 2, water can flow in the gap between roll shaft 1 and roller wall 2
Dynamic, being absorbed heat by heat transfer reduces the temperature of roller wall 2.Roller wall 2 connect with cast film machine to produce in cast film machine
Casting films are cooled down.The utility model proposes chill roll in, be provided on roll shaft 1 it is helical partition 11, partition 11
Gap between roll shaft 1 and roller wall 2 is divided to form multiple helical ducts 13, water is mobile to roller wall in helical duct 13
2 are cooled down.
The utility model proposes chill roll in, the roll shaft 1 include multiple baffles vertical with 1 axis of roll shaft
12, the baffle 12 makes the helical duct 13 form multiple cooling ducts 130.
In the present embodiment, the baffle 12 can further segmentation forms cooling duct 130 by helical duct 13.It is cooling
The length in channel 130 is shorter, and temperature difference of the water body before and after pipeline is smaller, and the temperature gap of different location can also be got in roller wall 2
It is small.The utility model proposes chill roll can guarantee that the temperature gap in roller wall 2 is small, guarantee casting films it is each in roller wall 2
The cooling effect of position is identical, prevents the cooling effect difference of casting films chill roll different location from causing membrane body damage or membrane body greatly
Ropy problem.
The roll shaft 1 include outlet pipe 15 among the roll shaft 1 and be located at 15 periphery of outlet pipe with it is described
Intake antrum 16 between 1 inner wall of roll shaft, the intake antrum 16 are connected to the cooling duct 130 by inlet opening 14a.It is described go out
Water pipe 15 is connected to the cooling duct 130 by apopore 14b；Water is in the cooling duct 130 by the inlet opening 14a
Flow to the apopore 14b.
In the present embodiment, water enters cooling duct 130 by intake antrum 16 and inlet opening 14a, in cooling duct 130
After cooling down to the heat absorption of roller wall 2, the roll shaft 1 is flowed out via apopore 14b and outlet pipe 15.Since water body is logical through supercooling
Road 130 cools down roller wall 2 after absorbing heat to roller wall 2, and the water temperature in outlet pipe 15 is greater than the water body temperature in intake antrum 16
Degree, for intake antrum 16 between outlet pipe 15 and cooling duct 130, the water body in intake antrum 16 can be in cooling duct 130
Water body cooled down, reduce cooling duct 130 in water temperature, improve cooling duct 130 in cooling of the water body to roller wall 2
Effect.
The utility model proposes chill roll in, in the same cooling duct 130, include at least an inlet opening
14a and include at least an apopore 14b；It is logical that the inlet opening 14a and apopore 14b is located at the cooling
130 both ends of road.
In the present embodiment, described to avoid lacking in cooling duct 130 problem that water body causes roller wall 2 that can not cool down
There are the inlet opening 14a and apopore 14b for the water body that circulates in cooling duct 130.Inlet opening 14a and apopore 14b distinguishes
Positioned at 130 two sides of cooling duct can guarantee that water body circulates in cooling duct 130 after be not detained in cooling duct 130,
Cause the problem of cooling effect difference.
Meanwhile it is opposite by the water (flow) direction in 11 two adjacent cooling ducts 130 of the partition.The same spiral
Water (flow) direction is identical or opposite in cooling duct 130 in channel 13.
In the present embodiment, the water body at 130 both ends of cooling duct has temperature difference.To prevent 2 edge of chill roll roller wall
The problem of 130 direction temperature of cooling duct is gradually increasing, causes 2 point-to-point transmission excessive temperature differentials of roller wall, the utility model proposes it is cold
But different from the position of inlet opening 14a by the apopore 14b in 11 two adjacent cooling ducts 130 of partition in roller, thus
Water body flow direction in 11 two adjacent cooling ducts 130 of partition is also just opposite.Water body in two cooling ducts 130
It complements each other to the cooling effect of roller wall 2, the water body in cooling duct 130 can be made to play the roller wall 2 of Different Plane identical
Cooling effect.
Since the water body being located in 11 two adjacent cooling ducts 130 of partition can be mutual to the cooling effect of roller wall 2
Supplement.So for (two i.e. adjacent along baffle 12 cooling ducts of different cooling ducts 130 in same helical duct 13
130), the position of inlet opening 14a and apopore 14b can be identical or different.If the position phase of apopore 14b and inlet opening 14a
Together, then water body flow direction is consistent in cooling duct 130 in same helical duct 13.If the position of apopore 14b and inlet opening 14a
Difference is set, then water body flow is contrary in cooling duct 130 in same helical duct 13.
The axis of the inlet opening 14a in the same cooling duct 130 and the axis angle of the apopore 14b exist
Between 90 ° to 180 °.
In the present embodiment, the too long water body that can reduce in cooling duct 130 is to the cooling effect of roller wall 2,130 mistake of cooling duct
Short, the water of consumption just will increase.In order to guarantee production requirement, while the consumption of water resource is reduced, cooling duct 130 should be kept
In a certain range.Due to the cooling duct 130 helically state, the axis of inlet opening 14a and apopore 14b be two not
Coplanar line.Cooling duct 130 is shorter, and the position of inlet opening 14a and apopore 14b are closer to inlet opening 14a and apopore
14b axis is formed by angle less than 90 °, will cause the waste of water body at this time.And cooling duct 130 is too long, inlet opening 14a with
The axis of apopore 14b is formed by angle greater than 180 °, and water body reduces the cooling effect of roller wall 2 at this time, 2 point-to-point transmission of roller wall
The temperature difference becomes larger.The axis angle of inlet opening 14a and apopore 14b is at 90 ° between 180 degree in turn, it is ensured that needs in production
Water body consumption is reduced in the case where asking, and reduces production cost.
The outlet pipe 15 includes multiple communicating pipe 14c, and the communicating pipe 14c is connected to the outlet pipe 15 and the cooling
Channel 130, the apopore 14b are located at the one end the communicating pipe 14c；The communicating pipe 14c is located in the intake antrum 16.
In the present embodiment, the outlet pipe 15 is located at 1 axle center of roll shaft, the cooling duct 130 be located at roll shaft 1 with
Between roller wall 2, the multiple communicating pipe 14c being arranged in intake antrum 16 are prevented for being connected to outlet pipe 15 and cooling duct 130 into water
The problem of water mixing in chamber 16 and outlet pipe 15, thermal convection causes water body to reduce by 2 cooling effect of roller wall in water body.
Certainly, the utility model can also have other numerous embodiments, be based on present embodiment, the ordinary skill of this field
Personnel's obtained other embodiments under the premise of not making any creative work, belong to the utility model and are protected
Range.
