Abstract

The utility model provides a novel air knife comprising a body and a base. The inner of the air knife is provided with an air guide structure communicated with an outside guide duct. The body of the air knife is positioned on the base by spiral group holes at both sides, wherein, the front end of the base of the air knife is provided with a guide plate bulging above a convex part of a tangent plane of a tuyere. The utility model has the advantages of simple and reasonable structure, convenient manufacture and easy use, can effectively remove liquor or water solidified and left on a plate body and provide convenience for following processes.

Description

Novel air knife

The utility model relates to a kind of wind-guiding cutter in the pressurized air drainage of outside can being gone into.

The structure of existing air knife as shown in Figure 3, mainly be by a body 2 and base 5 combinations, be provided with the structure of wind-guiding in inside, and communicate with the Gas inlet tube 3 of outside, in the pressurized air drainage of outside is gone into, average diffusion 8 blows out from the air port again, is provided with spiral shell group hole 4 in the both sides of the body 2 of air knife 1, so that air knife 1 is positioned on the tool rest.Air knife 1 is owing in the plate body process equipment, in order to the liquor or the moisture content that are stayed with fixed attention on the plate body are caught up with row, handle in order to subsequent drying.But there is following shortcoming in it: 8 inside, air port at air knife 1 are provided with slot-shaped spray road 10, regardless of the distance of spraying 10, will make pressurized gas be certain angular spread and 8 blow out from the air port, as the waterfall shape that flowing water was of water tap.Therefore the pressurized gas of not concentrating when diffusion blows out, no matter the angular adjustment of air knife why, all can't effectively catch up with venting to remove the liquor or the moisture content that are stayed with fixed attention on the plate body, its shortcoming is that gas that air port 8 blows out can't concentrate and constitute line planar 11 as the scraper, and be diffusion treatment only to the liquor or the moisture content of the brush row of catching up with, liquor of can't be effectively, thoroughly will stay with fixed attention or moisture content are removed, and this will or apply processing by great adverse effect to subsequent drying.

The purpose of this utility model just provides a kind of novel air knife, its tuyere bottom at air knife is protruded the plate body that forms water conservancy diversion, go out in action radius by water conservancy diversion restriction wind, for indiffusible existing planar, constitute invisible scraper, catch up with venting to remove stay with fixed attention liquor or moisture content on the plate body effectively, in order to follow-up processing.

The purpose of this utility model is achieved in that a kind of novel air knife, it comprises body and base, the structure that its inside is provided with wind-guiding communicates with the guide duct of outside, the body of air knife is positioned on the base by spiral shell group hole, both sides, and wherein said air knife base front end is provided with the guide plate that protrudes from air port tangent plane protuberance.

The utility model is simple and reasonable, and manufacturing, easy to use in use can will be removed liquor or the moisture content of staying with fixed attention on the plate body effectively, handles facilitating for following process.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a user mode schematic representation of the present utility model;

Fig. 2 is the air knife effect schematic representation of prior art.

Referring to Fig. 1, the utility model is a kind of novel air knife, air knife 1 comprises body 2 and base 5, the structure that is provided with wind-guiding in inside communicates with the guide duct 3 of outside, in the pressurized air drainage of outside is gone into, average diffusion 8 blows out from the air port again, is provided with spiral shell group hole 4 in the both sides of the body 2 of air knife 1, so that air knife 1 is positioned on the tool rest.Wherein air knife 1 base 5 front ends are provided with and protrude from air port 8 tangent plane protuberances 6, form guide plate 7.Can make air port 8 compression blow gas by guide plate 7, be that line is planar 11 in coloured distance, concentrates and the gas of line planar 11 blows out, and can reach the purpose of thorough removal liquor or moisture content effectively with the liquor or the moisture content that go to brush except that staying with fixed attention on the plate body.

Referring to Fig. 2, air knife 1 uses in the manufacturing equipment of plate body 9, is the processing before the drying process.Its upper and lower each one group of air port 8 is oppositely arranged (group only is shown among the figure), can make liquor or moisture content by being stayed with fixed attention on the plate body between the upper and lower air knife 1 be brushed eliminating by air knife 1.Use in the time, air knife 1 is optimum distance with 1-2mm with the distance of plate body 9, and the air port 8 of air knife 1 is the best with the angle of plate body 9 with 45 degree, and by both angle and distances, the gas that the air port 8 of air knife 1 is blown out is caught up with row's best results to the liquor or the moisture content that stay with fixed attention on the plate body 9.Moreover, because of the effect of guide plate 7, make the gas that blows out interior planar 11 for line in effective distance, by concentrating just as scraper, liquor or the moisture content stayed with fixed attention on the plate body 9 can be got rid of, handle facilitating for following process.

Claims

1, a kind of novel air knife, it comprises body and base, the structure that its inside is provided with wind-guiding communicates with the guide duct of outside, and the body of air knife is positioned on the base by spiral shell group hole, both sides, it is characterized in that: described air knife base front end is provided with the guide plate that protrudes from air port tangent plane protuberance.
