Abstract
The invention discloses the negative pressure system installed before coating machine, negative pressure cavity is arranged on extrusion coated head and the centre position of applicator roll is supported by support frame, the bottom of negative pressure cavity is connected with a negative tube and connected with negative pressure surge tank, the pipeline of one and negative-pressure cup insertion are connected with the negative pressure surge tank, the centre of the pipeline is equipped with pneumatic ball valve, being connected on this end pipe road of negative-pressure cup has another bye-pass, active regulating valve is housed on another bye-pass, the end of another bye-pass is equipped with regulation threshold switch, and there is the pipeline being connected with blower fan the another side of negative-pressure cup.The pipeline connected between the negative-pressure cup and negative pressure surge tank is higher than the pipeline that negative-pressure cup another side is connected with negative-pressure air fan.The technical program can protect good working environment, exclude the generation of dust, and increase coating clearance, which improves, is coated with a kind of apparent, negative pressure system of stable meniscus level.
Description
Technical field
The present invention relates to the negative pressure system installed between a kind of coater head and applicator roll.
Background technology
When the mixed liquor of existing coating is from the liquid outlet of coater head into applicator roll, it can be produced when mixed liquor is coated in applicator roll
A raw meniscus, if this meniscus is stablized not in time, can increase coating clearance, mixed liquor can be drawn with substrate surface with wind
It is long, the more attached dust being invisible to the naked eye is understood on substrate surface, so that the quality that product will be directly affected.
The content of the invention
The task of the present invention is to propose that one kind, by the rapid discharge of powder ash, eliminates the bubble easily occurred when being coated with, stable bent moon
Face, increase coating clearance improves the negative pressure system installed before the coating machine of the apparent negative pressure system of coating.
The task of the present invention, which is done in such a way that, is characterized in that：Negative pressure cavity is arranged on extrusion coated head and applicator roll
Centre position supported by support frame, the bottom of negative pressure cavity is connected with a negative tube and connected with negative pressure surge tank, and the negative pressure is delayed
Rush on tank and be connected with one and the pipeline of negative-pressure cup insertion, the centre of the pipeline is equipped with pneumatic ball valve, close to this end pipe of negative-pressure cup
Connect to have on road and active regulating valve is housed on another bye-pass, another bye-pass, the end of another bye-pass is equipped with regulation
There is the pipeline being connected with blower fan threshold switch, the another side of negative-pressure cup.The pipe connected between the negative-pressure cup and negative pressure surge tank
Road is higher than the pipeline that negative-pressure cup another side is connected with negative-pressure air fan.
The present invention has the following effects that：The technical program can protect good working environment, exclude the generation of dust, increase
Coating clearance, which improves, is coated with a kind of apparent, negative pressure system of stable meniscus level.
Brief description of the drawings
Fig. 1 is the structural representation of negative pressure system of the present invention.
Drawing explanation：1st, negative-pressure air fan, 2, negative-pressure cup, 3, pipeline, 4, pneumatic ball valve, 5, active regulating valve, 6, negative pressure delays
Rush tank, 7, negative tube, 8, negative pressure cavity, 9, another bye-pass, 10, regulation threshold switch.
Embodiment
Embodiment is described in detail with reference to the figures above, negative pressure cavity 8 is arranged on the interposition of extrusion coated head and applicator roll
Put and supported by support frame, the bottom of negative pressure cavity is connected with a negative tube 7 and connected with negative pressure surge tank 6, on the negative pressure surge tank 6
The pipeline 3 of one and negative-pressure cup insertion are connected with, the centre of the pipeline 3 is equipped with pneumatic ball valve 4, on this end pipe road of negative-pressure cup
Connection, which has, is equipped with active regulating valve 5 on another bye-pass 9, another bye-pass, the end of another bye-pass is equipped with regulating valve
Switch 10, there is the pipeline being connected with negative-pressure air fan 1 another side of negative-pressure cup.
The pipeline 3 connected between the negative-pressure cup and negative pressure surge tank is connected higher than negative-pressure cup another side with negative-pressure air fan
Pipeline.
During work, the formation of negative pressure is worked by negative-pressure air fan in negative pressure cavity, in the presence of draft, will be many in negative pressure cavity
Remaining gas runs through pipeline and buffering negative-pressure cup discharge is outdoor.Pressure in negative pressure cavity is less than ambient pressure, therefore mixed liquor
Energy stable meniscus between from liquid outlet into applicator roll, eliminates bubble, and increase coating clearance improvement is coated with apparent so as to reach
One resistant-walled working region.
Claims (2)
