Description
Technical Field
[0001] This utility model relates to the field of industrial spraying and drying equipment technology, and in particular to an automatic spraying device for gas cylinders. Background Technology
[0002] Chinese Patent CN2714163Y discloses a gas cylinder spraying device. This device comprises a suspended conveyor belt and a spraying apparatus. The suspended conveyor belt suspends the gas cylinder via hooks, allowing the cylinder to rotate during transport to pass through the spraying apparatus. The spraying apparatus consists of a top and bottom spray gun and a lifting spray gun, used to spray paint onto the top and bottom surfaces and the circumference of the gas cylinder, respectively. The key feature is that the top and bottom spray guns are mounted on a reciprocating translation mechanism. According to this structure, when the gas cylinder enters the spraying apparatus, the top and bottom spray guns can synchronously follow the rotating and translating gas cylinder via the reciprocating translation mechanism, uniformly spraying paint onto the top and bottom surfaces of the cylinder. The spraying equipment described above is used by setting the bottle body vertically and setting multiple bottles on the conveyor belt for continuous operation, while driving the bottle body to rotate. This results in a complex structure, large size, and high manufacturing cost. It is only suitable for large-scale production and is not suitable for manufacturers with small production scale and small production volume of composite gas cylinders. Summary of the Invention

[0004] To solve the above problems, the present invention adopts the following solution: an automatic gas cylinder painting device, characterized in that the automatic gas cylinder painting device includes a rotating assembly, a conveying assembly, a spraying assembly, a control circuit board, and a spraying chamber composed of an inlet baffle, an outlet baffle, a front wall panel, and a rear wall panel; the conveying assembly includes a circulating track and a hoisting mechanism, the circulating track is located at the top and passes through the spraying chamber, and the hoisting mechanism is located on the circulating track and moves along the circulating track by a servo motor to convey the gas cylinder into the spraying chamber; the rotating assembly includes a lifting mechanism and a rotating... The motor and lifting mechanism are located at the bottom of the spray booth, and the rotary motor is mounted on the lifting mechanism. A base is mounted on top of the rotary motor to contact the gas cylinder and drive it to rotate. The spraying assembly includes a movable nozzle and a spray gun. A vertical track is provided in the middle of the front wall panel and / or rear wall panel of the spray booth. The movable nozzle is mounted on the vertical track and is driven by a servo motor to move along the vertical track. The movable nozzle is connected to the spray gun to spray paint onto the gas cylinder that has moved to the middle of the spray booth. The inlet baffle, outlet baffle, lifting mechanism, rotary motor, spray gun, and servo motor are all controlled by a control circuit board.
[0005] Furthermore, the automatic painting device for gas cylinders is characterized in that both the inlet baffle and the outlet baffle adopt a double-door design, and a pneumatic push-pull rod is connected to the back of each door to control the opening or closing of the inlet baffle and the outlet baffle.
[0006] Furthermore, the automatic gas cylinder painting device is characterized in that a material sensor is provided in front of the inlet baffle of the painting chamber to detect whether there is a gas cylinder that needs to be transported to the painting chamber.
[0007] Furthermore, the automatic gas cylinder painting device is characterized in that two position sensors are provided on both sides of the vertical guide rail inside the painting chamber to detect whether the gas cylinder delivered to the painting chamber has entered the painting position.
[0008] Furthermore, the automatic gas cylinder painting device is characterized in that the lifting mechanism has a mounting tray on its top rod, and the rotary motor is installed inside the mounting tray.
[0009] Furthermore, the automatic painting device for gas cylinders is characterized in that the hoisting mechanism is set on a circulating track, and the hoisting mechanism is connected in series via a transmission chain. A servo motor is provided on the transmission chain, and a control circuit board is used for control.
[0010] Furthermore, the automatic gas cylinder painting device is characterized in that a quick-drying chamber is provided behind the painting chamber. The quick-drying chamber includes a drying chamber composed of an inlet door, an outlet door, a front wall panel, and a rear wall panel, as well as a hot air inlet, a tail gas outlet, and a hot air furnace. The hot air furnace generates dry hot air and delivers it to the drying chamber through the hot air inlet. The tail gas outlet is used to discharge tail gas to the purification system.
[0011] The technical effects of this utility model are as follows: The automatic gas cylinder painting device of this utility model includes a rotating component, a conveying component, a spraying component, a control circuit board, and a spraying chamber composed of an inlet baffle, an outlet baffle, a front wall panel, and a rear wall panel. The conveying component transports the gas cylinder into the spraying chamber, the rotating component lifts and rotates the gas cylinder, and after the spraying component completes the painting, the rotating component retracts, and the conveying component transfers the gas cylinder out. A material receiving sensor is installed in front of the inlet baffle of the spraying chamber. When the gas cylinder moves to this position, the material receiving sensor is triggered, the inlet baffle and the outlet baffle open, and the gas cylinder enters the spraying chamber. The gas cylinder that has completed painting in the spraying chamber moves out of the spraying chamber. When the gas cylinder reaches the painting position, the position sensor is triggered, the conveying component stops working, and the gas cylinder is held in the painting position. At this time, the rotating component starts, the lifting component raises the rotating motor to contact the gas cylinder, and then the rotating motor starts, driving the gas cylinder to rotate. Then the spraying component starts, and the gas cylinder rotates continuously while being sprayed with paint, achieving 360° painting.
[0012] After the spraying is completed, the gas cylinder is transferred to the quick-drying chamber, where it is rapidly dried with hot air until it is ready for transfer. Then it is transferred to the shade drying chamber for static drying. Attached Figure Description
