Abstract
The utility model provides a single-layer curtain head device for a curtain coating. A left cavity and a right cavity of the device are connected by a connecting bolt, an end plate is fixed on an end face of a cavity encircled by the left cavity and the right cavity by a fixing bolt, reflux holes are formed on the end plate, a feed hole is formed on the left cavity, the left cavity, the right cavity and the end plate form a large refining cavity, a slot is arranged at the lower part of the large refining cavity, the lower part of the slot is provided with a small refining cavity, the refining cavity is encircled by the left cavity, the right cavity and the end plate, and a metering slot is arranged at the lower part of the small refining cavity. Material is fed from the two ends on a whole horizontal banner and the middle in a multi-point manner, and the banner of material feeding is ensured to be uniform; by adopting two-cavity structure, refining is further realized; the two ends of the large cavity are provided with the reflux holes, and a dead point is prevented from being generated in fluid in the cavities.
Description
Technical field
The utility model relates to the papermaking equipment field, specially refers to a kind of individual layer for curtain coating curtain head unit that falls.
Background technology
The curtain head that falls of curtain coating is that coating is measured into the device that banner keeps the coating curtain of uniform thickness.Current, the curtain head unit that falls that is used for curtain coating still adopts one-sided charging, single chamber refining, and this structure can't accurately guarantee coating in the homogeneity of banner upward pressure, thereby causes the unstable of coating curtain, and can only produce a coating curtain.
Summary of the invention
The purpose of this utility model is to provide a kind of multiple feed, the curtain coating individual layer of metering and the multi-cavity refining curtain head unit that falls repeatedly.
For achieving the above object, the technical solution of the utility model is:
A kind of individual layer for curtain coating curtain head unit that falls, comprise left cavity, right cavity, end plate, charging hole, large refining chamber, slit, little refining chamber, metering slit and return port, the left cavity of this device is connected with connecting bolt with right cavity, end plate is fixed on the end face of the cavity that left cavity and right cavity form with set bolt, have return port on the end plate, have charging hole on the left cavity, left cavity, right cavity and end plate consist of large refining chamber, slit is arranged at the bottom in large refining chamber, the bottom of slit has by left cavity, the little refining chamber that right cavity and end plate consist of, the metering slit is arranged at the bottom in little refining chamber.
Technique effect of the present utility model is:
1, this device two ends and simultaneously charging of middle multiple spot on whole banner, the banner uniformity of assurance charging;
2, adopt two cavity configurations, further refining, and large two ends, chamber is provided with return port, guarantees that the chamber inner fluid does not have the dead point;
3, adopt twice slit metering, further make the fluid layer fluidisation;
4, this device can guarantee that coating grows banner homogeneous behind the curtain head, stable.
Description of drawings
Fig. 1, the curtain coating individual layer curtain head unit front section view that falls;
Fig. 2, the curtain coating individual layer curtain head unit side view that falls.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with Fig. 1 and Fig. 2.
Referring to Fig. 1 and Fig. 2, left cavity 1 and right cavity 3 are fixed together by some connecting bolts 2, and two end plates 4 are fixed on the end face of the cavity that left cavity 1 and right cavity 3 form by some hold-down screws 5; Left cavity 1 inside is provided with the charging hole 6 more than three, and left cavity 1, right cavity 3, end plate 4 consist of large refining chamber 7, slit 8, little refining chamber 9 and metering slit 10.
During work, coating enters large refining chamber 7 by each charging hole 6 on the left cavity 1, coating homogenize in this chamber, part coating enters little refining chamber 9 by slit 8, and coating is 9 interior further homogenizes in little refining chamber, and unnecessary coating is back to vanish system by the return port 11 on the two ends end plate 4, further the coating of homogenize is again by after long metering slit 10 laminarizations, flow out the curtain head, fall to page, form the coating curtain.
