DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] As Figure 1 - Figure 3 shown, the high-performance sheet metal spraying device of the utility model includes an equipment main body 1. The equipment main body 1 includes a cleaning device 2, a drying device 3, a spraying device 4, and a drying device 5 installed on a base 6. The above-mentioned devices are all provided with a feeding port and a discharging port for the sheet metal to pass through. Among them, the cleaning device 2 cleans the surface of the sheet metal to be sprayed through a spray pipe 23, and preliminarily dries the sheet metal after cleaning through a blowing assembly 24. The drying device 3 further dries the surface of the sheet metal through the waste heat input by a heat recovery device 7, so that the sheet metal reaches a clean and dry state before spraying and processing. The spraying device 4 provides paint through a coating mixing chamber 42 and evenly sprays the surface of the sheet metal in a spraying chamber 43 through a spray gun assembly 45. The drying device 5 is used to quickly dry the paint on the surface of the sprayed sheet metal, reducing the drying time of the paint and improving the production efficiency.

[0020] As Figure 1 , Figure 2 shown, the cleaning device 2 is arranged at one end of the base 6. The cleaning device 2 includes a housing 21, a first feeding belt 22, a spray pipe 23 and a blowing component 24 arranged in the housing 21. A cleaning container is further arranged on the base 6 on one side of the housing 21. The cleaning container is used for containing sheet metal cleaning agent. The spray pipe 23 is connected to the cleaning container through a pipeline. The spray pipe 23 extracts the sheet metal cleaning agent in the cleaning container to clean the sheet metal entering the cleaning device 2. The sheet metal enters the housing 21 through the first feeding port 25 and then falls onto the first feeding belt 22 near the first feeding port 25 in the housing 21. The first feeding belt 22 carries the sheet metal to move. There are two spray pipes 23, which are respectively arranged on the inner walls on both sides of the housing 21 and are located above the first feeding belt 22. The liquid outlet of the spray pipe 23 faces the first feeding belt 22. The blowing component 24 is provided with an air box. A fan is arranged in the air box. The air box is arranged at the top end inside the housing 21 and is close to the first discharging port. An air outlet is arranged on the bottom surface of the air box. The air outlet is located directly above the first feeding belt 22 and faces the first feeding belt 22. A recovery pool 26 is further arranged in the housing 21 below the first feeding belt 22. A liquid outlet is opened on one side of the recovery pool 26. The liquid outlet is connected to an external filtering device through a pipeline. The recovery pool 26 is used for recovering and storing the sheet metal cleaning agent sprayed by the spray pipe 23. During use, the sheet metal is fed onto the first feeding belt 22 in the housing 21 through the first feeding port, and then the first feeding belt 22 carries the sheet metal to move towards the first discharging port. When the first feeding belt 22 carries the sheet metal and travels below the spray pipe 23, the spray pipe 23 extracts the sheet metal cleaning agent in the cleaning container to clean the upper surface of the sheet metal. The sprayed sheet metal cleaning agent passes through the first feeding belt 22 and falls into the recovery pool 26 below it. As the first feeding belt 22 moves, the sheet metal gradually passes through below the spray pipe 23 and travels to below the air box. The fan blows cold air or hot air, which is blown onto the upper surface of the sheet metal through the air outlet to initially dry the cleaned sheet metal. Subsequently, the first feeding belt 22 conveys the sheet metal to the first discharging port and the sheet metal passes through the first discharging port. When a part of the sheet metal passes through, its end extends into the feeding port on the adjacent drying device 3.

[0021] As Figure 1As shown, the drying device 3 includes a first shell 21 with a cavity, a second feeding belt is arranged in the first shell 21, the first feeding belt 22 is symmetrically arranged with the second feeding belt, and the second feeding belt is composed of a frame, rollers arranged on both ends of the frame, a motor and a metal mesh belt sleeved on the roller. The upper end surface of the second feeding belt is lower than the openings of the feed port and the discharge port, which is convenient for sheet metal transportation. The sheet metal falls on the second feeding belt and is carried by the second feeding belt to move. The waste heat transported thereto by the heat recovery device 7 increases the temperature in the first shell 21, thereby quickly drying the sheet metal in the first shell 21 to prepare for sheet metal spraying. The second feeding belt carries the sheet metal through the first shell 21 and passes through the discharge port on the first shell 21. After passing through a part, the starting end extends into the feed port on the adjacent spraying device 4.

[0022] like Figure 1 , Figure 3 As shown, the completely dried sheet metal passes through the feed port on the spraying device 4 and enters the material channel 46. The spraying device 4 includes a box body 41. The box body 41 is provided with a paint mixing chamber 42 and a spraying chamber 43 separated by a partition 44. The paint mixing chamber 42 is located above the spraying chamber 43. The paint mixing chamber 42 is provided with a stirring assembly for stirring, mixing and storing the paint. The box body 41 is also provided with a spray gun assembly 45, which is arranged on the side of the partition 44 facing the spraying chamber 43. The spray gun assembly 45 includes an air compressor, a material pipe 452 and a nozzle 453. The air compressor 451 is arranged on the partition 44 as an air source. The spray gun assembly 45 passes through the partition 44 through the material pipe 452 and is connected to the paint mixing chamber 42. The spray gun assembly 45 extracts the mixed paint from the paint mixing chamber 42 through the material pipe 452, and uses the air pressure provided by the air compressor 451 as power to spray the paint through the nozzle 453; there are two material channels 46, and the two material channels 46 are arranged opposite to each other. The material channels 46 are arranged on the inner walls on both sides of the box body 41. Specifically, the material channels 46 are located in the spraying chamber 43 and directly below the spray gun assembly 45. Each material channel 46 has a limiting groove welded on the inner wall. A vertically arranged conveyor belt is arranged on the concave surface of the limiting groove. The two material channels 46 are symmetrically arranged. The limiting groove openings of the material strip material channels 46 are opposite to each other. The space between the two material channels 46 forms a feeding part. When in use, the two side edges of the sheet metal extending horizontally extend into the two material channels 46 respectively, and the ends of the side edges are aligned with the two material channels 46. The conveyor belt is close together, and after the sheet metal is clamped by the conveyor belt, it moves along the length direction of the limiting groove. When the material channel 46 carries the sheet metal to the bottom of the nozzle 453, the three nozzles 453 arranged in parallel spray paint at the same time to spray the surface of the sheet metal. After the sheet metal is carried by the material channel 46 and passes under the nozzle 453, the upper surface of the sheet metal is evenly sprayed. The conveyor belt continues to move, and the sprayed sheet metal is passed out from the discharge port of the spraying device 4. After a part of the sheet metal is passed out, it is extended into the feed port on the drying device 5.

[0023] likeFigure 1 As shown, the drying device 5 is arranged at the other end of the base 6 away from the cleaning device 2. The drying device 5 includes a second housing 21 with a cavity. Inside the second housing 21, there is a third loading belt symmetric to the second loading belt and an electric heating component (not shown in the figure). The electric heating component is installed at the top inside the second housing and is directly above the third loading belt. The electric heating component is an electric heating tube commonly used in the prior art. By energizing, the heating wire generates heat, and then the metal tube serving as the housing heats up. The heat is dispersed inside the second housing 21. The temperature above the third loading belt closest to the electric heating component is the highest. After spraying the sheet metal, it is carried and transported by the third loading belt. The third loading belt passes the sheet metal under the electric heating component. The high temperature generated by the electric heating component dries the paint on the surface of the sheet metal. The third loading belt continues to drive the sheet metal to move until it is sent out from the discharge port, completing the spraying of the gold spray; at this time, the heat recovery device 7 extracts hot air through the air inlet 72 extending into the drying device 5 and transports it through the ventilation pipe to the drying device 3 where the air outlet 73 extends. This process is achieved by the exhaust fan 71 arranged on the ventilation pipe for air extraction and exhaust. Through the heat recovery device 7, the waste heat is reused, which is beneficial to energy conservation and environmental protection.
