preferably, described drain pipe is provided with for controlling the pilot operated valve device of described drain pipe flow quantity.

preferably, described escape pipe is provided with for controlling the Pneumatic valve of described escape pipe throughput.

utilization due to technique scheme, the utility model compared with prior art has following advantages: spray equipment of the present utility model, wherein by base material being closely attached to pressure roller bottom, and adopt Compressed Gas to make bubbler spray out vaporific liquid towards substrate surface with spraying the form of confluxing with liquid, thereby make liquid spray comparatively even of substrate surface, after spraying, through the pressure roller with annular recess, push again, can make spraying with uniform liquid cover the surface of base material, promote the effect of spraying, be beneficial to the rolling of base material simultaneously, promoted the rolling efficiency of base material.This spray equipment is simple in structure, easy to use, has effectively improved spraying effect and the spray efficiency of base material.

Accompanying drawing explanation

the structural representation that accompanying drawing 1 is spray equipment of the present utility model.

The specific embodiment

below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.

spray equipment shown in Figure 1, this spray equipment comprises frame 2, is located at rotating pressure roller 3 in frame 2, frame 2 is provided with liquid storage tank 4, pressure roller 3 in frame 2, be positioned at liquid storage tank 4 above.The base material 1 of processing to be sprayed transmits by outside winding device length direction along himself in frame 2, the axis parallel of pressure roller 3 is in the width of base material 1, and base material 1 is closely attached to the lower surface of pressure roller 3 and the extruding that stands pressure roller 3 is squeezed even in the process transmitting.In frame 2, be also provided with bubbler 5, the mouth spray of this bubbler 5 is aimed at the surface that base material 1 is positioned at pressure roller 3 rears, and this fore-and-aft direction refers to the fore-and-aft direction that base material 1 transmits.

this spray equipment also comprise store the fluid reservoir 6 of liquid for spraying, with the drain pipe 7 of fluid reservoir 6 intracavity inter-connections, for control the liquid outlet quantity size of drain pipe 7 pilot operated valve device 9, store Compressed Gas air accumulator (not shown), and the escape pipe 8 of the intracavity inter-connection of above-mentioned air accumulator, for controlling the Pneumatic valve 10 of escape pipe 8 throughputs, spraying can be the mixed liquor of antitack agent and water with liquid, the mouth of pipe of drain pipe 7 intersects with the mouth of pipe of escape pipe 8 and is connected with the mouth spray of bubbler 5.Like this, when spraying, first regulate pilot operated valve device 9, in mouth spray, spray liquid spraying liquid, regulate again Pneumatic valve 10, compressed air is passed in bubbler 5 to conflux with liquid with spraying, now the mouth spray of bubbler 5 sprays out the liquid that is vaporific, this vaporific liquid spray is on the surface of base material 1, externally, under the rolling active force of winding device, base material 1 transmits along its length, is with dynamic pressure roller 3 to rotate in transport process, pressure roller 3 rolls base material 1 in rotation process, make vaporific spraying with liquid more even in the surface distributed of base material 1.Meanwhile, base material 1 is closely attached to the tension force of capable of regulating base material 1 on pressure roller 3, prevents from occurring the phenomenons such as sideslip in base material 1 wrapup procedure, has improved the rolling efficiency of base material 1.

shown in Figure 1, for make pressure roller 3 to base material 1 roll process in damage is not caused in base material 1 surface, pressure roller 3 comprises roll body, be coated on the elastic rubber layer of above-mentioned roll body outer surface, on this elastic rubber layer, also offer a plurality of long and narrow annular recess, these a plurality of annular recess are axially spaced apart thick and fast along pressure roller 3, the groove depth of annular recess, groove width is 0.05～0.1mm, like this, base material 1 is when pressure roller 3 rolls, the lip-deep spraying of base material 1 moves in the annular recess on pressure roller 3 with liquid rotating, when departing from base material 1 surface, pressure roller 3 can cover equably the surface of base material 1, what make that the lip-deep spraying of base material 1 applies with liquid is more even.Meanwhile, when base material 1 thickness is when bigger than normal, also can guarantee that base material 1 and pressure roller 3 lower surfaces fit tightly, what make that spraying applies with liquid is more abundant.

shown in Figure 1, in spraying, unnecessary spraying uses liquid from the width two side inflow liquid storage tanks 4 of base material 1, can reclaim use again.Liquid storage tank 4 bottoms offer the return port 11 with its intracavity inter-connection, and the aperture of return port is 2～4cm, is connected with return duct 12 on return port 11, and by outside, connecting reservoir vessel can use the spraying of reclaiming in liquid storage tank 4 by liquids recovery, avoid waste.

above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
