Background technology

A large amount of smog are the hard nut to cracks in the industry in the dispense tip air knife demister system, coating head device is meant: as shown in Figure 1, it by the strip on the coiled strip tube 51 52 around being coated with roller 53 to giving, give and be coated with roller 53 belows and immerse being coated with in the feed liquid of coating material cartridge 58, be coated with roller 53 coating is coated onto on the strip 52 by giving, strip 52 has become the needed strip product that has been coated with coating by breast roll 54 backs behind drying baker 55.Unnecessary coating need separated with strip 52 through the strip that gives after being coated with roller 53, in device commonly used, air knife 56 is set above breast roll 54, air knife 56 high speed thin layer air-flows with unnecessary coating along the breast roll axial surface with its strip that blows off, clout is set below breast roll collects box collection clout 57, can produce a large amount of smog in the collection process like this, contain a large amount of harmful substances in the smog, product quality is impacted, indoor environment is caused great pollution and the health of the staff under the working environment is constituted threat greatly.

The utility model content

The purpose of this utility model is in order to solve the smog hard nut to crack that present dispense tip air knife produces at work, and a kind of dispense tip air knife demister that overcomes above problem is provided.

Adopt following technical scheme for achieving the above object:

A kind of dispense tip air knife demister, it mainly comprises frame, air knife, separator box, air-introduced machine, gas-liquid separating box upper port one inclined-plane of particular design is provided with a breast roll opening, the outer upside of breast roll opening is provided with an air blowing air knife, be provided with walking roller below the separator box, separator box is arranged on the guide rail of frame by walking roller, the bottom side relative with the breast roll opening is arranged to a rare air outlet of drawing downwards, the air outlet lower end is can be to breast roll opening reverse slide butt joint inclined-plane, fixing and the corresponding guide duct of air outlet on the frame, the guide duct upper port is provided with and docks the inclined-plane applying interface that the inclined-plane connects, the guide duct lower end is provided with manifold trunk, manifold trunk is connected with induced duct, and the other end of induced duct connects air-introduced machine.

Be provided with in the wherein said separator box and the corresponding deep bead of air knife.

The beneficial effects of the utility model are: the dispense tip air knife demister of this spline structure, coating head device is installed in position, the walking roller of separator box is passed separator box on guide rail to coating head device, make the breast roll of the breast roll opening of separator box over against the holding portion coating head device, the inclined-plane applying interface of the butt joint inclined-plane of air outlet lower end and guide duct is fitted closely, in the use, the air knife high speed thin layer air-flow that is arranged on the outer upside of breast roll opening with unnecessary coating along the breast roll axial surface with its arcuation strip surface of blowing off, the gas that is mixed with coating is blown into separator box, under the effect of separator box inner chamber deep bead gas is separated with coating, coating is collected the clout groove by the collection mouth of bottom with it; Gas after the separation is extracted out outdoor down by the drive of air-introduced machine by air outlet, manifold trunk and induced duct, the mixing smog that can avoid fully producing in the process causes great pollution to indoor environment and influence product quality and to the threat of the health of the staff working environment under formation; This device can move with coating head device in orbit by walking roller and easily separate, and is simple to operate, convenient.

Description of drawings

Fig. 1 is the coating head device of prior art;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:
