Abstract
The utility model relates to a casing machine, in particular to a casing machine which is used for producing polyester films and sheet materials, which mainly comprises a casing nozzle and a casing roll and is characterized in that the casing roll is made of an outer cylinder which is connected with a speed reducer and an inner cylinder which is fixed on an inner frame of the outer cylinder, and a hollow cavity is arranged between the outer cylinder and the inner cylinder. The casing machine has the advantages of compact structure and fast cooling, which can enable polyester melt when pressing close to the surface of a cooling roll to be cooled fastly, thereby forming regular solid casing pieces under the situation for not increasing the width and diameter of the cooling roll face of the casing machine.
Description
Technical field:
The utility model relates to a kind of casting machine, specifically is a kind of casting machine that polyester film and sheet material are used of producing.
Technical background:
To be a kind of external force effect by electrostatic adsorption device press close to chill roll surface at low temperature, best bright finish rapidly with polyester fondant with casting machine, melt cooled off fast form the device of solid casting sheet.Polyester fondant is cooling fast when making the casting sheet, otherwise degraded easily, in order to realize this purpose, present casting machine generally is width and the diameter that strengthens the curtain coating roll surface, to increase the flow of cooling water in the casting roller.The raising of manufacturing cost of casting machine and the waste of the energy have so just been caused.
Summary of the invention:
The utility model is under the situation of width that does not strengthen casting machine cooling roll surface and diameter, a kind of casting machine that polyester fondant is cooled off when pressing close to the chill roll surface fast.
The technical solution of the utility model adopts following technical characterictic to constitute:
A kind of casting machine mainly is made up of curtain coating mouth and casting roller, it is characterized in that: casting roller is made of inner core and urceolus, and inner core is fixed on the urceolus internal rack, and urceolus links to each other with reductor.The casting roller inner core is by eccentric tube, the punching pipe, and sparge pipe constitutes, interior all diameters of eccentric tube are less than outer circumference diameter, the outer tube inner surface of perimeter surface and casting roller forms a cavity in the eccentric tube, and the punching pipe links to each other with sparge pipe in the middle of being positioned at eccentric tube, and sparge pipe is the Zhou Kaiyou water spout in eccentric tube.
The utility model compact conformation, cooling can make polyester fondant be cooled to qualified solid casting sheet fast when pressing close to the chill roll surface under the situation of width that does not strengthen casting machine cooling roll surface and diameter rapidly.

Specific embodiment:
A kind of casting machine as shown in Figure 1 mainly is made up of curtain coating mouth (1) and casting roller (2).Casting roller (2) has a cavity (3) by constituting with inner core as shown in Figure 2 between urceolus (1) and the inner core (2), and inner core is fixed on urceolus (1) internal rack, and urceolus (1) can uniform rotation under the drive of reductor.Inner core (2) is by as shown in Figure 3 eccentric tube (2), punching pipe (3), sparge pipe (4) constitutes, interior all diameters of eccentric tube (2) are less than outer circumference diameter, the outer tube inner surface of perimeter surface and casting roller forms a cavity in the eccentric tube, punching pipe (3) links to each other with sparge pipe (4) in the middle of being positioned at eccentric tube (2), and sparge pipe is Zhou Kaiyou hole for water spraying (5) in eccentric tube.During work, cooling water is through as shown in Figure 3 punching pipe (3) and sparge pipe (4), spray the position that the high-temperature polyester melt that flows out touches casting roller (2) by hole for water spraying (5) from curtain coating mouth (1) as shown in Figure 1, also form cooling water flow in the cavity (3) between urceolus as shown in Figure 1 (1) and the inner core (2), and cavity (3) is big more, cooling water flow is big more, the high-temperature polyester melt can in time carry out heat exchange fully with casting roller (2), melt can cool off fast, when it peels off casting roller (2), formed qualified polyester solid casting sheet.
