[0011] Preferably, a connecting groove and a connecting pipe are provided in the rotating body, one end of the connecting groove is connected to the air flow groove, the other end of the connecting groove is connected to the air delivery groove, one end of the connecting pipe is connected to the paint chamber, and the other end of the connecting pipe is connected to the spraying groove.

[0012] Preferably, a recovery groove is provided at the center of the rotating body, a recovery pipe is provided at the center of the fixed body, and the recovery pipe is connected to the recovery groove; a recovery chamber is provided outside the frame, a suction pump is provided inside the recovery chamber, and the suction pump is connected to the recovery pipe through a pipeline.

[0013] Preferably, a visual sensor is provided on the bracket of the rack, a hanging rope is provided on one side of the bottom of the recovery pipe, and a hook is provided on the hanging rope.

[0014] Preferably, an electric heating wire is arranged in the air flow groove, and the cross section of the placement table is in the shape of a basin with high sides and a low middle.

[0015] Before the chair is placed, the controller first controls the electromagnetic coil in the rotating slot to start, and the electromagnetic coil generates magnetic force after starting, which attracts the magnetic conductor in the rotating shaft, and then the rotating shaft rotates under the action of the magnetic force, and then the rotating shaft drives the spray block to rotate, so that the axis of the spray block is in a vertical state with the axis of the fixed body, and then the electromagnetic coil is powered off; Then the staff can place the chair on the surface of the placement table, or hang the chair in the air through hooks and hanging ropes. When the chair is placed, the controller controls the visual sensor on the bracket of the rack to recognize the shape of the chair. The visual sensor converts the image signal of the chair into an electrical signal and transmits it to the controller, which analyzes it. When the shape of the chair is read by the controller, the controller controls the electromagnetic coil in the rotating slot to energize again, so that several spray blocks rotate to the side close to the chair, so that the spray blocks move according to the shape of the chair. At this time, several spray blocks wrap the chair, and the distance between each spray block and the surface of the chair is equal. Then the controller first controls the electric heating wire in the air flow slot to start and the air pump to start. The air pump transports the outside gas to the air flow slot through the pipeline. After being transported to the air flow slot, the outside gas is heated by the electric heating wire, and then the temperature of the outside gas rises. Then the outside gas is transported to the connecting slot through the air flow slot, and finally transported to the gas delivery slot through the connecting slot, and then transported through several gas delivery pipes, so that the gas delivery slot of each spray block is transported with outside gas. Then the outside gas is ejected from the gas outlet. Since the gas outlet is in an arc shape and faces the side close to the axis of the rotating body, the outside gas ejected from the two adjacent spray arms is ejected towards each other, so that the space between the two adjacent spray arms is blocked by the airflow formed by the outside gas ejection. Then the two airflows converge and move to the side close to the chair, and then the outside airflow acts on the chair to blow off the dust on the surface of the chair, and the heat carried by the outside gas is also transferred to the surface of the chair, so that the temperature of the chair surface rises, thereby improving the efficiency of subsequent paint drying. In the process of cleaning and heating the chair by the outside gas, the controller controls the suction pump to start, and the suction pump extracts from the recovery pipe, so that the gas in the space surrounded by the several spray arms moves to the side close to the recovery tank, and is transported to the recovery pipe through the recovery tank, and finally transported to the recovery chamber for storage through the recovery pipe; After a period of cleaning and heating, the controller controls the water pump in the liquid storage tank to start, the water pump extracts the paint, transports it to the paint cavity through the pipeline, transports it to the connecting pipe through the paint cavity, and transports it to the spray tank through the connecting pipe, and finally transports it to the spray tank in each spray block through the infusion pipe. Then the controller controls the No. 1 motor to start, the driving shaft of the No. 1 motor drives the rotating gear to rotate, the rotating gear meshes with the gear ring when rotating, and then the gear ring drives the rotating body to rotate, and the rotating body drives several spray arms to rotate when rotating, and several spray arms perform orbital motion around the chair. While the spray arms are orbiting, the controller controls the spray port to open, and the paint is then sprayed toward the chair through several spray ports; Since the distance between each spray block and the chair is equal, the time it takes for the paint to move to the chair after being sprayed from the spray block is also the same, thereby achieving a uniform spraying effect. In addition, since several air flows block the gap between two adjacent spray arms, the space surrounded by the several spray arms is separated from the outside world, so that the paint cannot splash to the side of the spray arm away from the chair, thereby ensuring the cleanliness during spraying, avoiding the paint from floating everywhere, thereby causing pollution to the working environment, and reducing the difficulty of equipment cleaning; at the same time, when the paint flows through the spray tank, since the air delivery tank is adjacent to the spray tank, the heat of the external air flowing in the air delivery tank will be transported to the spray tank through the spray block, thereby heating the paint in the spray tank, and then when the paint is sprayed from the spray port, the paint carries heat. When the paint adheres to the surface of the chair, the external gas will also accelerate the airflow movement around the chair, so that the subsequent chair is dried faster under the action of heat and airflow movement, thereby improving the drying effect of the chair, thereby saving the time of painting the chair; Since the cross-section of the placement table is a basin shape with high sides and low middle, the edge of the placement table also blocks the dispersion of the paint, interacts with the airflow ejected from the air outlet, suppresses the dispersion of the paint, and further suppresses the dispersion of the paint in the rack.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. External gas is ejected from the air outlet. Since the air outlet is arc-shaped and faces the side close to the axis of the rotating body, the external gas ejected from the two adjacent spray arms is ejected toward each other, so that the space between the two adjacent spray arms is blocked by the airflow formed by the external gas ejection. Then the two airflows converge and move to the side close to the chair, and then the external airflow acts on the chair to blow off the dust on the surface of the chair, and the heat carried by the external gas is also transferred to the surface of the chair, so that the temperature of the chair surface rises, thereby improving the efficiency of subsequent paint drying.

[0017] 2. Since the distance between each spray block and the chair is equal, the time it takes for the paint to move to the chair after being sprayed from the spray block is also the same, thereby achieving a uniform spraying effect. In addition, since several air flows block the gap between two adjacent spray arms, the space surrounded by several spray arms is separated from the outside world, and the paint cannot splash to the side of the spray arm away from the chair, thereby ensuring the cleanliness during spraying, avoiding the paint from scattering everywhere, and causing pollution to the working environment, and reducing the difficulty of equipment cleaning; at the same time, when the paint flows through the spray tank, since the air supply tank is adjacent to the spray tank, the heat of the external gas flowing in the air supply tank will be transported to the spray tank through the spray block, and then the paint in the spray tank will be heated, so that when the paint is sprayed from the spray port, the paint carries heat. When the paint adheres to the surface of the chair, the external gas will also accelerate the airflow movement around the chair, so that the subsequent chair will dry faster under the action of heat and airflow movement, thereby improving the drying effect of the chair, thereby saving the time of painting the chair.

[0018] 3. Since the cross-section of the placement table is a basin shape with high sides and low middle, the edge of the placement table also blocks the dispersion of the paint, interacts with the airflow ejected from the air outlet, suppresses the dispersion of the paint, and further suppresses the dispersion of the paint in the rack.

[0030] Working principle of the present invention: Before the chair is placed, the controller first controls the electromagnetic coil in the rotating slot 271 to start, and the electromagnetic coil generates magnetic force after starting, and the magnetic force attracts the magnetic conductor in the rotating shaft 272, and then the rotating shaft 272 rotates under the action of the magnetic force, and then the rotating shaft 272 drives the spray block 27 to rotate, so that the axis of the spray block 27 is in a vertical state with the axis of the fixed body 21, and then the electromagnetic coil is powered off; Then the staff can place the chair on the surface of the placement table 11, or hang the chair in the air through the hook and the hanging rope 32. When the chair is placed, the controller controls the visual sensor on the bracket of the rack 1 to recognize the shape of the chair. The visual sensor converts the image signal of the chair into an electrical signal and transmits it to the controller, which analyzes it. When the shape of the chair is read by the controller, the controller controls the electromagnetic coil in the rotating slot 271 to be energized again, so that the plurality of spray blocks 27 rotate toward the side close to the chair, so that the spray blocks 27 move according to the shape of the chair. At this time, several spray blocks 27 wrap the chair, and the distance between each spray block 27 and the surface of the chair is equal. Then, the controller first controls the start-up of the electric heating wire and the air pump in the air flow slot 211, and the air pump transports the external gas to the air flow slot 211 through the pipeline. After being transported to the air flow slot 211, the external gas is heated by the electric heating wire, and the temperature of the external gas rises. Then, the external gas is transported to the connecting slot 251 through the air flow slot 211, and finally transported to the gas delivery slot 28 through the connecting slot 251, and transported through a plurality of gas delivery pipes 281, so that the gas delivery slot 28 of the spray block 27 is transported with external gas each time; Then, the external gas is ejected from the gas outlet 282. Since the gas outlet 282 is in an arc shape and faces the side close to the axis of the rotating body 25, the external gas ejected from the two adjacent spray arms 26 is ejected in opposite directions, so that the space between the two adjacent spray arms 26 is blocked by the airflow formed by the external gas ejection. Then, the two airflows converge and move to the side close to the chair, and then the external airflow acts on the chair to blow off the dust on the surface of the chair, and the heat carried by the external gas is also transferred to the surface of the chair, so that the temperature of the chair surface rises, thereby improving the efficiency of subsequent paint drying. In the process of cleaning and heating the chair by the external gas, the controller controls the suction pump to start, and the suction pump extracts the recovery pipe 31, so that the gas in the space surrounded by the several spray arms 26 moves to the side close to the recovery tank 30, and is transported to the recovery pipe 31 through the recovery tank 30, and finally transported to the recovery chamber for storage through the recovery pipe 31; After a period of cleaning and heating, the controller controls the water pump in the liquid storage tank to start, the water pump extracts the paint, transports it to the paint chamber 212 through the pipeline, transports it to the connecting pipe 252 through the paint chamber 212, and transports it to the spray tank 29 through the connecting pipe 252, and finally transports it to the spray tank 29 in each spray block 27 through the infusion tube 292, then the controller controls the No. 1 motor to start, the driving shaft of the No. 1 motor drives the rotating gear 24 to rotate, and the rotating gear 24 engages with the gear ring 221 when rotating, and then the gear ring 221 drives the rotating body 25 to rotate, and the rotating body 25 rotates and drives a plurality of spray arms 26 to rotate, and the plurality of spray arms 26 revolve around the chair. While the spray arms 26 revolve, the controller controls the spray port 291 to open, and the paint is then sprayed toward the chair through the plurality of spray ports 291.
