Background

The spraying method is a coating method for spraying or flowing paint on the surfaces of arches. The coating method is an improvement of dip coating, needs to be added with a plurality of devices, is suitable for a mass flow line production mode, and is a relatively economic and efficient coating method. It is to pour the coating onto the object through a nozzle by pressure or gravity; there are also these many differences in the requirements of the spray coating.

The coating thickness of the product is controlled by the size of the nozzle or the width of the narrow slit, and the coating thickness can directly influence whether defective products appear after the materials are dried.

Disclosure of Invention

The invention provides a pressure-adjustable quick spray knife which combines gas and liquid, adjusts spraying pressure and sprays uniformly.

In order to solve the technical problem, the invention provides a pressure-adjustable quick spray knife which comprises a knife body and a knife head, wherein the knife head is fixed at the bottom of the knife body; the utility model discloses a coating machine tool, including blade, trachea and coating pipe, the blade top is passed through splint and is connected with trachea and coating pipe, the input port of trachea and coating pipe is connected with cylinder hose and feed hose respectively, it has gaseous reposition of redundant personnel passageway and coating reposition of redundant personnel passageway to put through respectively on trachea and the coating pipe bottom lateral wall, gaseous reposition of redundant personnel passageway and coating reposition of redundant personnel passageway are terminal to be communicated with the tool bit through converging the groove.

Furthermore, the air pipe is connected with the coating pipe in a sealing mode through a connecting piece, and a temporary storage cavity is expanded on a feeding and distributing channel connected with the bottom of the coating pipe.

Furthermore, the front and the back of the output port of the cutter head are respectively provided with a gas nozzle and a coating nozzle, and a round-head metal sheet is fixedly inserted between the gas nozzle and the coating nozzle.

Furthermore, two groups of turning nuts are screwed at two ends of the gas nozzle.

After adopting the structure, compared with the prior art, the invention adopts the structure of the gas-liquid double-nozzle, thereby solving the technical problem that sundries are adhered to the surface of the object; the pressure regulating valve can change the jet pressure of the feeding nozzle according to the requirement of the coating thickness of a product; in order to avoid the interference of the gas nozzle with the coating efficiency of the coating nozzle, the spraying direction of the gas nozzle can be timely adjusted by adjusting the turning nut.

Detailed Description

As shown in fig. 1, 2 and 3, the pressure-adjustable quick spray knife comprises a knife body and a knife head, wherein the knife head is fixed at the bottom of the knife body; the utility model discloses a coating machine tool, including blade 1, trachea 5 and coating pipe 6, the input port of trachea 5 and coating pipe 6 is connected with cylinder hose 7 and feed hose 8 respectively, it has gas shunting channel 11 and coating shunting channel 14 to put through respectively on the lateral wall of trachea 5 and coating pipe 6 bottom, gas shunting channel 11 and coating shunting channel 14 are terminal to be linked together with tool bit 2 through converging groove 12. The invention relates to a pressure-adjustable quick spray knife with double nozzles. The inside cylinder hose 7 and the feed hose 8 that are provided with respectively of blade, cylinder hose 7 can spray gas to will treat the impurity or the dust clearance on the product surface of spraying, give corresponding spraying environment. Meanwhile, the feeding hose 8 can uniformly spray the coating on the surface of the product.

As shown in fig. 1, 2 and 3, the air tube 5 and the paint tube 6 are hermetically connected by a connecting piece 3, and a temporary storage cavity 13 is expanded on a feed branch passage 14 connected to the bottom of the paint tube 6. Wherein, in order to prevent trachea 5 and coating pipe 6 intercommunication connecting piece 3 has been installed between trachea 5 and the coating pipe 6, reaches sealing connection's effect, leaves the chamber of keeping in 13 between connecting piece 3 right side and the coating pipe 6 simultaneously, the chamber of keeping in 13 temporary storage coatings to the phenomenon that can not appear the coating backward flow when supplying liquid scram and the air cavity appears.
