Abstract
The utility model 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, a pipeline with negative-pressure cup insertion is 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, equipped with regulation threshold switch, there is the pipeline being connected with blower fan the another side of negative-pressure cup for the end of another bye-pass.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
It the utility model is related to the negative pressure system installed between a kind of coater head and applicator roll.
Background technology
The mixed liquor of existing coating from the liquid outlet of coater head enter applicator roll when, can be produced when mixed liquor is coated in applicator roll
A raw meniscus, if this meniscus is stablized not in time, it be able to can be drawn with substrate surface with wind increase coating clearance, mixed liquor
It is long, the more attached dust being invisible to the naked eye is understood on substrate surface, so as to which the quality of product will be directly affected.
The content of the invention
Task of the present utility model is to propose that one kind discharges rapidly powder ash, eliminates the bubble easily occurred when being coated with, stable
Meniscus, increase coating clearance improve the negative pressure system for being coated with and being installed before the coating machine of apparent negative pressure system.
Task of the present utility model, which is done in such a way that, is characterized in that：Negative pressure cavity is arranged on extrusion coated head and painting
The centre position of cloth rewinder roll is supported by support frame, and the bottom of negative pressure cavity is connected with a negative tube and connected with negative pressure surge tank, described negative
A pipeline with negative-pressure cup insertion is connected with pressure surge tank, the centre of the pipeline is equipped with pneumatic ball valve, close negative-pressure cup this
Being connected on end pipe road has another bye-pass, active regulating valve is housed on another bye-pass, the end of another bye-pass is equipped with
Threshold switch is adjusted, there is the pipeline being connected with blower fan the another side of negative-pressure cup.Connected between the negative-pressure cup and negative pressure surge tank
Pipeline be higher than the pipeline that is connected with negative-pressure air fan of negative-pressure cup another side.
The utility model has the following effects that：The technical program can protect good working environment, exclude the generation of dust,
It is apparent to increase coating clearance improvement coating, a kind of negative pressure system of stable meniscus level.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model negative pressure system.
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
A pipeline 3 with negative-pressure cup insertion is 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 has another bye-pass 9, and active regulating valve 5 is housed on another bye-pass, and 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, will be more in negative pressure cavity in the presence of draft
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
From liquid outlet enter applicator roll between can stable meniscus, eliminate bubble, it is apparent so as to reaching that increase coating clearance improves coating
One resistant-walled working region.
