Abstract
The utility model discloses an air knife with uniform coating, which comprises an air inlet cavity and an air outlet cavity, wherein the air inlet cavity is connected with a flue pipe, an air outlet of the air outlet cavity is an air knife edge in a long and straight sew shape, the width of the air knife edge is bigger than the width of a painted matter, the width direction of the air knife edge is vertical to the length direction of the painted matter, the air knife edge is parallel to the surface of the painted mater, an included angle between the air knife edge and the direction of motion is an acute angle, and the direction of blowing wind of the air knife edge is opposite to the direction of motion of the painted mater. The utility model has the advantages of uniform surface coat, better painting quality, simple structure, and lower investment cost.
Description
Technical field
The utility model relates to the external coating technology, especially relates to a kind of air knife that is used for equilibrium surface coverage.
Background technology
The external coating quality of ribbon, especially the uniformity quality of face coat, very big to the influence of the attractive in appearance and durability after its application, and for the ribbon of surface-coated insulating barrier, because of the uniformity of face coat can not get guaranteeing that its insulating properties can be subjected to severe impairment.The face coat uniformity not only depends on coating quality, spraying equipment, and also depend on uniform coating technology to a great extent, general uniform coating adopts material soft and that have an adsorption capacity to embrocate the ribbon of application or use the uniform coating roller, effect with first kind of mode uniform coating is relatively poor, the particularly very easy coating at two edges of ribbon that makes is wiped, and adopt the uniform coating roller can obtain preferable quality, but the Adjustment System of roll gap makes its complex structure, invests bigger.
The utility model content
In order to solve the deficiency in the above-mentioned technology, the purpose of this utility model is to provide a kind of uniform coating quality good, simple in structure uniform coating air knife.
In order to solve the problems of the technologies described above, the utility model uniform coating air knife comprises air-inlet cavity, the air-out chamber; It is characterized in that: described air-inlet cavity links to each other with airduct, the air outlet in air-out chamber is the air knife mouth, it is a long vertical masonry joint, the width of air knife mouth is greater than the width of painting object, the width of air knife mouth is vertical with the length direction of painting object, and the air knife mouth is surperficial parallel with painting object, and the angle of the air knife and the painting object direction of motion is an acute angle, and the air-out direction of air knife mouth is opposite with the direction of motion of painting object.The cross-sectional area of air knife mouth is less than the cross-sectional area of airduct.
The utility model adopts the air knife uniform coating, because the air knife mouth is a long vertical masonry joint, the cross-sectional area of air knife mouth is less than the cross-sectional area of airduct, the wind of certain pressure enters air knife from airduct, and evenly spraying the wind of certain pressure along the length direction of air knife mouth, this wind is removed unnecessary coating as cutter on the coating of ribbon, make its face coat even, do not wipe the coating at two edges of ribbon, thereby guaranteed the external coating quality.And, satisfy the coating of different viscosities and the external coating quality requirement of coating layer thickness by regulating the blast and the air quantity of blast pipe.The utility model uniform coating quality is good, and structure is very simple, and cost of investment is low.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is the structural representation of the utility model uniform coating air knife.
Fig. 2 looks schematic diagram for the left side of Fig. 1.
The A-A generalized section of Fig. 3 the utility model uniform coating air knife.
Fig. 4 is the enforcement schematic diagram of the utility model uniform coating air knife.
The specific embodiment
From Fig. 1-as can be known shown in Figure 4, the utility model uniform coating air knife comprises air-inlet cavity 4, air-out chamber 5; The top of air-inlet cavity 4 and airduct 3 welderings connect, the bottom weldering of the top in air-out chamber 5 and air-inlet cavity 4 is linked as an integral body, and two chambeies communicate, the air outlet of 5 bottoms, air-out chamber is air knife mouths 2, is a long vertical masonry joint, and the width of air knife mouth 2 is greater than the width of painting object 6, the width of air knife mouth 2 is vertical with the length direction of painting object 6, and air knife mouth 2 is surperficial parallel with painting object 6, and air knife 1 is an acute angle with the angle of painting object 6 directions of motion, and the air-out direction of air knife mouth 2 is opposite with the direction of motion of painting object 6.The cross-sectional area of air knife mouth 2 is less than the cross-sectional area of airduct 3.
Painting object 6 is the aluminium strip (for Breadth Maximum) of 260 * 0.23mm, coating is insulated paint, and the width of air knife mouth 2 is 300mm, and an air knife 1 is equipped with on the two sides of aluminium strip 6 respectively, air knife 1 is 45 ° with the angle of aluminium strip 6 directions of motion, and air knife 1 is installed in the upper right side of paint bath 8.Aluminium strip 6 enters the paint bath 8 that insulated paint is housed from a left side, walk around the back from the below of cylinder 9 and go out paint bath 8 from the right side, the aluminium strip 6 of this moment is coated with full insulated paint, when aluminium strip 6 moves to air knife 1 place, the air knife 1 reverse wind that blows scrapes off unnecessary insulated paint gently as cutter, the insulated paint that scrapes flows in the paint bath 8, and through staying the layer of even paint film around 6 surfaces of the aluminium strip behind the air knife 1, the insulated paint on aluminium strip 6 surfaces solidifies behind baking oven 7 again.
Claims (2)
