Chamber, is provided with rotation handle on foam-discharging valve, and the front of the upper cover is provided with lock, and it is not plane that, which there is the gradient at the back side of upper cover,
The shape of upper cover both sides of the face is the triangle of a unfilled corner, and the shape of the liquid storage cylinder matches with upper cover to be snapped together,
The clamp of locking lock corresponding with upper cover is installed on liquid storage cylinder, inlet is installed at the center of the face view of liquid storage cylinder, is born
Pressure chamber is arranged on extrusion coated head and the centre position of applicator roll is supported by supporting rack, and the bottom of negative pressure cavity is connected with a negative pressure
Pipe is connected with negative pressure surge tank, and a pipeline with negative-pressure cup perforation, the centre of the pipeline are connected with the negative pressure surge tank
Equipped with pneumatic ball valve, being connected on this end pipe road of negative-pressure cup has another bye-pass, and active regulating valve is housed on another bye-pass,
Equipped with threshold switch is adjusted, there is the pipeline being connected with wind turbine in the another side of negative-pressure cup for the end of another pipeline.The feed liquor
The diameter of mouth is more than the diameter of inlet outlet.The pipeline connected between the negative-pressure cup and negative pressure surge tank is another higher than negative-pressure cup
The pipeline that one side is connected with negative-pressure air fan.
The utility model has the following effects that：The coater head that the technical program is related to is easy to clean, coating fluid buffer stream
It is dynamic not produce bubble, ensure product quality, the generation of waste product is reduced, so as to improve the economic benefit of enterprise；The technical program energy
Good working environment is protected, excludes the generation of dust, increases coating clearance, stablizes a kind of negative pressure system of meniscus level.

Embodiment
The coater head transverse direction half section that the technical program is related to is in clothes rack shape, and equipped with corner angle, upper cover can open, and overcome
The shortcoming that prior art upper cover cannot be opened, and the upper cover of head leads to liquid storage cylinder and is provided with foam-discharging valve, prevent bubble
Produce, improve the quality of coating, increase the storage capacity of liquid storage cylinder, liquid stabilising can be made, buffering flowing is in drops by liquid outlet
It is sticked and coated on applicator roll and quickly spreads, the cured film thickness of coating is uniform, quality of finished product good.
For specific embodiment as shown in Figure 1, coater head 1 is fixed in rack against applicator roll, coater head 1 includes upper cover
With liquid storage cylinder 6, the upper cover and liquid storage cylinder are to be flexibly connected, and upper cover 2 can be opened, the outer shape of the upper cover and liquid storage cylinder
In variable cross-section clothes hanger shape type, there is no corner angle on round and smooth transition face, its both ends of the top surface flat smooth of upper cover are provided with foam-discharging valve
3, the foam-discharging valve valve body is provided with exhaust pipe, and exhaust pipe, through liquid storage cylinder is fallen into, is pacified in the hole that upper cover is processed on foam-discharging valve
Equipped with rotation handle, by the opening and closing of rotation handle control foam-discharging valve, due to being provided with exhaust pipe in liquid storage cylinder, therefore in coating fluid such as
It can be discharged in time by air bleeding valve after there is bubble.The front of the upper cover is provided with lock, and the back side of upper cover has the gradient not to be
Plane, the shape of upper cover both sides of the face are the triangles of a unfilled corner.
The shape of the liquid storage cylinder matches with upper cover to be snapped together, and locking lock corresponding with upper cover is provided with liquid storage cylinder
5 clamp is detained, inlet 4 is installed at the center of the face view of liquid storage cylinder, the diameter of the inlet is exported more than inlet
Diameter, effectively mixed liquor can be controlled to slowly enter liquid storage cylinder, avoid producing bubble, the inside of the liquid storage cylinder as shown in Fig. 2,
Coating fluid is in laterally homogeneous drawout from import, is extruded by the liquid outlet 7 of coating head and uniformly spread on base material, is solved very well
The shortcomings that finished product thickness is uneven, liquid storage cylinder inner chamber body be according to fluid mechanics principle be designed as half droplet-shaped variable cross-section of longitudinal direction and
Horizontal clothes hanger type section cavities.
Negative pressure cavity 15 is arranged on extrusion coated head and the centre position of applicator roll is supported by supporting rack, the bottom of negative pressure cavity
It is connected with a negative tube 14 to connect with negative pressure surge tank 13, a pipe with negative-pressure cup perforation is connected with the negative pressure surge tank 13
Road 10, the centre of the pipeline are equipped with pneumatic ball valve 11, and being connected on this end pipe road of negative-pressure cup has another bye-pass 16, another
Active regulating valve 5 is housed, equipped with threshold switch 17 is adjusted, the another side of negative-pressure cup has for the end of another pipeline on bye-pass
The pipeline being connected with negative-pressure air fan 8.
The pipeline 10 connected between the negative-pressure cup and negative pressure surge tank connects higher than negative-pressure cup another side and negative-pressure air fan
The pipeline connect.
During work, the mixed liquor that upstream is made is entered by the inlet set on liquid storage cylinder, is in by the outlet of liquid storage cylinder
Drops is dripped on rotating applicator roll, when bubble is such as had in coating process, the foam-discharging valve of upper cover is opened in time, by gas
Bubble discharge, reduces the generation of waste product, when work will such as clean liquid storage cylinder after a certain period of time, need to only open on liquid storage cylinder main-vision surface
Lock on clamp and upper lid, upper cover just can be opened, easy to clean, quick, so as to improve final product quality；Negative pressure in negative pressure cavity
Formation is worked by negative-pressure air fan, under the action of draft, gas unnecessary in negative pressure cavity is run through pipeline and buffering is negative
Press tank discharge outdoor.Pressure in negative pressure cavity is less than ambient pressure, therefore mixed liquor enters between applicator roll from liquid outlet and can stablize
Meniscus, eliminates bubble, increase coating clearance improves the coating appearance, so as to reach a resistant-walled working region.
