Make great efforts to improve process for machining and manufacturing and optimization mechanical structure to improve coating accuracy, but in terms of feed and online froth breaking still
By the way of traditional.Point type is fed, it is necessary to which manually or mechanically mode laterally shakeouts coating fluid.Storing plate is open type, is caused
A large amount of solvent volatilizations, are unfavorable for artificial operation and influence coating performance.Air can be brought during coating into, make to adulterate largely in coating fluid
Bubble.
Utility model content
For above-mentioned the deficiencies in the prior art part, the problem of the utility model is solved is：There is provided one kind can effectively drop
The volatilization of low solvent, stable coating fluid viscosity, coating fluid is avoided to flow down the closed feed comma of the bubble brought into caused by air
Apparatus for coating.
To solve the above problems, the technical scheme that the utility model is taken is as follows：
A kind of closed feed comma apparatus for coating, including back flow roll, comma roller, sealing feeding system；Described back flow roll and
Comma roller is arranged in an axially parallel mode；Described back flow roll and the side of comma roller mutually recline；Described sealing feeding system is located at
Between back flow roll and comma roller；Described sealing feeding system includes feed bottom plate, gas-tight silo, charging pump；Described gas-tight silo peace
On feed bottom plate；Described charging pump is arranged in gas-tight silo；The outside of described gas-tight silo is provided with feeding mouth；It is described
Gas-tight silo inner side be provided with discharging opening.
Further, described gas-tight silo is in bending structure；The medial end and bottom plate of described gas-tight silo leave gap structure
Into discharging opening.
Further, described discharging opening is located at back flow roll side.
Further, in addition to negative pressure extractor fan；Described negative pressure extractor fan is arranged on above sealing feeding system；Institute
The negative pressure extractor fan stated produces closed suction function to sealing feeding system.
Further, described negative pressure extractor fan includes negative pressure cabin, air draft pipe；Described air draft pipe is arranged on negative pressure
The outside in storehouse；Described negative pressure cabin is covered in the upper end of gas-tight silo；Described negative pressure cabin extends to the sidepiece of comma roller.
The beneficial effects of the utility model
Sealing feeding system of the present utility model can effectively reduce solvent volatilization, stable coating fluid viscosity；Using feed
Pump can effectively control the coating fluid accumulated at comma coating head with the mode that feed chamber is combined, and discharging opening gap is uniform,
Avoid the pollution manually or mechanically to coating fluid；Vacuumized inside negative pressure cabin, can effectively remove the dirty band of liquid at comma roller
Enter the bubble caused by air, and the peripheral environment at coating head can be optimized significantly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model content is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of closed feed comma apparatus for coating, including back flow roll 2, comma roller 1, sealing feeding system 3.
Described back flow roll 2 and comma roller 1 are arranged in an axially parallel mode.Described back flow roll 2 and the side of comma roller 1 mutually recline.Described
Feeding system 3 is sealed to be located between back flow roll 2 and comma roller 1.Described sealing feeding system 3 includes feed bottom plate 32, gas-tight silo
31st, charging pump.Described gas-tight silo 31 is arranged on feed bottom plate 32.Described charging pump is arranged in gas-tight silo 31.Institute
The outside for the gas-tight silo 31 stated is provided with feeding mouth 33.The inner side of described gas-tight silo 31 is provided with discharging opening 34.Further preferably, institute
The gas-tight silo 31 stated is in bending structure.The medial end and bottom plate of described gas-tight silo 31 leave gap and constitute discharging opening 34.Enter
Preferably, described discharging opening 34 is located at the side of back flow roll 2 to one step.Further preferably, in addition to negative pressure extractor fan 4.Described is negative
Extractor fan 4 is pressed to be arranged on the top of sealing feeding system 3.Described 4 pairs of sealing feeding systems 3 of negative pressure extractor fan produce closed
Suction function.Further preferably, described negative pressure extractor fan 4 includes negative pressure cabin 41, air draft pipe 42.Described air draft pipe
42 are arranged on the outside of negative pressure cabin 41.Described negative pressure cabin 41 is covered in the upper end of gas-tight silo 31.Described negative pressure cabin 41 extends
To the sidepiece of comma roller 1.
Sealing feeding system 3 of the present utility model can effectively reduce solvent volatilization, stable coating fluid viscosity；Using feed
Pump can effectively control the coating fluid accumulated at comma coating head with the mode that feed chamber is combined, and discharging opening gap is uniform,
