Abstract
The utility model discloses a main cold roll of a cast film line, which comprises an outer barrel. an inner barrel arranged in the outer barrel, a water inlet arranged at one end of the outer barrel, and a water outlet arranged at the other end of the outer barrel. The main cold roll is characterized in that a spiral groove is arranged on the outer surface of the inner barrel; the inner wall of the outer barrel and the spiral groove form a spiral water flow channel, and the water inlet and the water outlet are communicated with the spiral water flow channel. The utility model overcomes the deficiency in the prior art, and provides a double-layer and large-diameter main cold roll of a cast film line which has the advantages that the plastic film can be duly cooled, the cooling is sufficient, and the production efficiency is high.
Description
Technical field
The utility model relates to the casting roller that is used to cool off in a kind of plastic film production process, particularly the cold roller of a kind of master of cast film machine.
Background technology
At present, utilize cast film machine to produce in the process of plastic sheeting, plastics under the molten condition are extruded from flat-die head lip and are poured into the chill roll surface, back formation film is cooled rapidly, chill roll generally relies on water quench, but its diameter of chill roll that is used to cool off film in the prior art is generally all smaller, cool off untimely, insufficient, cause the transparency of film not high, the quality instability, because the restriction of chill roll size, make that the linear velocity of plastic sheeting is not high in the production process, thereby influenced the efficient of producing.The wall thickness that adds existing its roller of chill roll is generally all bigger, and heat-conductive characteristic is relatively poor.
The utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, to provide a kind of and can make the plastic sheeting cooling in time, cooling off fully the bilayer that production efficiency is high, the cold roller of major diameter cast film machine master.
In order to achieve the above object, the utility model adopts following scheme:
The cold roller of the master of cast film machine, comprise urceolus, in urceolus, be provided with inner core, urceolus one end is provided with water inlet, the other end is provided with delivery port, it is characterized in that: be provided with helicla flute on its outer surface of inner core, outer tube inner wall and helicla flute form the spiral water flow passage, described water inlet and delivery port and spiral water flow channel connection mutually.
The cold roller of the master of aforesaid cast film machine is characterized in that being provided with the spiral stream guidance bar on its outer surface of described inner core, and its outer surface of spiral stream guidance bar and inner core forms helicla flute.
The cold roller of the master of aforesaid cast film machine, it is characterized in that being respectively equipped with the gripper shoe that to seal urceolus at the urceolus two ends, described gripper shoe and inner core form intake antrum and water chamber respectively, on the gripper shoe of urceolus one end, be provided with into water spindle nose, the gripper shoe of the other end is provided with out water tap, be positioned at described water inlet spindle nose on the axis body of intake antrum and be evenly equipped with a plurality of inlet openings, go out on the axis body that water tap is positioned at water chamber to be evenly equipped with a plurality of apopores described.
The cold roller of the master of aforesaid cast film machine is characterized in that its diameter of described urceolus is for being not less than 1200mm.
The cold roller of the master of aforesaid cast film machine is characterized in that its wall thickness of described urceolus is 8mm.
The cold roller of the master of aforesaid cast film machine is characterized in that at described water inlet spindle nose and go out to be evenly equipped with six holes on the water tap respectively.
In sum, advantage of the present utility model: it adopts the double layer large diameter design the utility model, add that the outer tube wall thickness makes the film of extruding from cast film machine to obtain in time and cooling fully by cold roller the master of the utility model cast film machine, so because the linear velocity of film running can be bigger in the big production process of the diameter of main cold roller, thereby enhance productivity.
Description of drawings
Fig. 1 is a generalized section of the present utility model;
Fig. 2 be among Fig. 1 water inlet spindle nose A-A to generalized section.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further described:
As illustrated in fig. 1 and 2, the cold roller of the master of the utility model cast film machine, comprise urceolus 1, in urceolus 1, be provided with inner core 2, urceolus 1 one ends are provided with water inlet 4, and the other end is provided with delivery port 5, it is characterized in that: be provided with helicla flute 3 on inner core 2 its outer surfaces, urceolus 1 inwall and helicla flute 3 forms the spiral water flow passages, described water inlet 4 and delivery port 5 and spiral water flow channel connection mutually.
On described inner core 2 its outer surfaces, be provided with spiral stream guidance bar 6 in the utility model, spiral stream guidance bar 6 forms helicla flute 3 with inner core 2 its outer surfaces, be respectively equipped with the gripper shoe 7 that to seal urceolus 1 at urceolus 1 two ends, described gripper shoe 7 forms intake antrum 8 and water chamber 9 respectively with inner core 2, on the gripper shoe 7 of urceolus 1 one ends, be provided with into water spindle nose 10, the gripper shoe 7 of the other end is provided with out water tap 11, be positioned at described water inlet spindle nose 10 on the axis body of intake antrum 8 and be evenly equipped with a plurality of inlet openings 12, go out on the axis body that water tap 11 is positioned at water chamber 9 to be evenly equipped with a plurality of apopores 13 described.
Wherein 1 its diameter of the urceolus described in the utility model is not less than 1200mm, and urceolus 1 its wall thickness is 8mm; At described water inlet spindle nose 10 with go out to be evenly equipped with six holes on the water tap 11 respectively.
Cooling water is entered from the water inlet 4 of the water inlet spindle nose 10 of main cold roller, flow to intake antrum 8 through six side inlet openings 12, flow into six helical flow paths again, flow back into water chamber 9 then, the delivery port 5 that is pooled to out water tap 11 from six side apopores 13 that go out water tap 11 spills out at last.
The effect of main cold roller is in order to cool off film.The film of extruding from cast film machine is pasting the surface cool of leading cold roller, because the diameter of main cold roller is the major diameter of 1200mm in the utility model, the girth that is it is very long, make the film cooling in time, fully, also by having only 8mm because of the outer tube wall thickness of main cold roller, make that the heat exchange of the utility model product is rapid, the film cooling is accelerated.
