The beneficial effects of the utility model are: it can improve the heat dissipation and protection effects of the device, and make the installation and disassembly of the spraying mechanism more convenient, and at the same time, it can make the spraying mechanism climb, improve the flexibility of the device, and enable the device to adapt to spraying work at different heights.

[0003] Although the existing sprayer can spray the inhaled paint outward through atomization and can be flexibly adjusted up and down, there are still other problems in the use process. For example, it does not have a dust suction and purification function. The sprayer will generate a large amount of particulate matter and harmful gases during the painting process. If the spraying component is in a leaking state, the harmful gases generated during the spraying process will be inhaled into the human body and will also cause pollution to the surrounding environment. It is also inconvenient to position the cylindrical workpiece. In order to prevent the cylindrical workpiece from shifting during the spraying process, a bonding method is usually adopted. Glue is applied to the bottom of the workpiece and then it is pasted to the designated position, which is time-consuming and labor-intensive. In order to solve the above-mentioned problems, we propose a rotary sprayer. Utility Model Content

[0020] 1. The utility model opens the box door first and puts the workpiece into the fixed frame. When placing the workpiece, it needs to be covered on the two clamping plates. Then, the handle is held by hand to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it drives the two threaded plates to move outward synchronously through the cooperation of the slide rail and the slider. When the threaded plate moves, it drives the clamping plate to push the workpiece and clamp it at the center, which can facilitate the clamping and fixing of the cylindrical workpiece. The operation is simple and convenient, so that the workpiece is automatically in the center spray point position after being fixed, and the flexibility is good.

[0021] 2. The utility model starts the motor, centrifugal pump and axial flow fan at the same time. After starting, the motor will drive the mounting frame and the atomizing nozzle to rotate around the workpiece. After starting, the centrifugal pump will suck the paint and spray it out from the atomizing nozzle. After starting, the axial flow fan will rotate the internal impeller. When the impeller rotates, it will suck the gas in the lower chamber through the suction hole. After being sucked in, the gas will be discharged from the exhaust port under the adsorption of the activated carbon filter. It can have the function of dust removal and purification, thereby ensuring the health of people around, improving the surrounding environment, and having high practicality.
