[0024] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a screening device for powder coating production.

[0025] The specific technical solution includes a bottom half-cylinder 1, with a top half-cylinder 14 rotatably connected to the top of the bottom half-cylinder 1. A screening screen cylinder 2 is installed inside the bottom half-cylinder 1, with connecting pipes 3 and connecting discs 5 at both ends of the screening screen cylinder 2. A rotating pipe 4 is rotatably connected to one end of the bottom half-cylinder 1, and a motor 6 is installed at one end of the bottom half-cylinder 1. A rotating column 7 is installed on the output shaft of the motor 6. A disassembly assembly 8 is installed inside the bottom half-cylinder 1. The disassembly assembly 8 includes a sliding groove 801, an arc-shaped block 802, and a fixing hole 806. The two sliding grooves 801 are respectively installed on the outer walls of the rotating pipe 4 and the rotating column 7. The arc-shaped block 802... A slider 803 is provided on the outer wall of the bottom of the 02. The slider 803 is slidably connected to the inside of the slide groove 801. A spring 804 connected to the slider 803 is provided on the inner wall of the slide groove 801. A fixing screw 805 is threaded into the top of the arc block 802. Two fixing holes 806 are respectively provided on the outer walls of the connecting pipe 3 and the connecting plate 5. The bottom end of the fixing screw 805 is threaded into the inside of the fixing hole 806. By disassembling and assembling the assembly 8, different screening cylinders 2 can be easily replaced according to the particle size of the powder coating to be screened. It can screen powder coatings of different particle sizes and has a wider range of applications.

[0026] In specific implementations, such as Figure 1 and Figure 2As shown, a feed hopper 12 is provided at one end of the bottom half cylinder 1, and the feed hopper 12 is rotatably connected to the rotating tube 4. The feed hopper 12 will not affect the rotation of the rotating tube 4, while allowing the powder coating to enter the interior of the rotating tube 4.

[0027] In specific implementations, such as Figure 1 and Figure 4 As shown, an anti-blocking component 9 is provided at the bottom of the bottom half-cylinder 1. The anti-blocking component 9 includes a moving block 901, a motor 903, and a slide bar 905. The anti-blocking component 9 is used to automatically clean the mesh of the screening cylinder 2 to prevent the mesh of the screening cylinder 2 from becoming clogged.

[0028] Furthermore, motor 2 903 is fixedly installed at one end of the bottom half cylinder 1, and a lead screw 904 is installed on the output shaft of motor 2 903, which can drive the lead screw 904 to rotate.

[0029] Furthermore, the movable block 901 is threaded onto the outside of the lead screw 904, and a cleaning brush 902 is provided on the outer wall of the movable block 901. The cleaning brush 902 contacts the screening cylinder 2 and can clean the mesh of the screening cylinder 2.

[0030] Furthermore, the slide rod 905 is fixedly installed inside the bottom half-cylinder 1, and the moving block 901 is slidably sleeved on the outside of the slide rod 905, so that the slide rod 905 can guide the moving block 901.

[0031] In specific implementations, such as Figure 1 and Figure 2 As shown, the bottom of the screening cylinder 2 is provided with a discharge gate 10, and the bottom half cylinder 1 is provided with a discharge trough 11. The bottom half cylinder 1 is provided with a support leg 13. The discharge gate 10 is used to discharge large particles of powder coating that have not passed through the screening cylinder 2.

[0032] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0033] In use, the powder coating is placed inside the feed hopper 12. The powder coating enters the connecting pipe 3 through the rotating pipe 4 and then enters the screening cylinder 2. Motor 6 is turned on to rotate the screening cylinder 2, which can screen the powder coating. The powder coating falls through the discharge chute 11 as it falls through the screening cylinder 2. Motor 903 is turned on to rotate the lead screw 904, which causes the moving block 901 to synchronously move the cleaning brush 902 to clean the mesh of the screening cylinder 2, preventing the mesh of the screening cylinder 2 from becoming clogged, thus achieving self-cleaning and anti-clogging functions. Finally, the screws fixing the discharge gate 10 are unscrewed. The powder coating that does not pass through the screening cylinder 2 falls down. When the screening cylinder 2 needs to be replaced according to the powder coating particles to be screened, the top half cylinder 14 is rotated to open it, the fixing screw 805 is threaded out from the fixing hole 806, the arc block 802 is loosened, and the tension of the spring 804 can pull the slider 803 and the arc block 802 to move. At this time, the arc block 802 moves away from the end of the screening cylinder 2, and the screening cylinder 2 is moved upward, so that the screening cylinder 2 can be removed and replaced. This makes the screening device able to screen powder coatings of different particle sizes, and its application range is wider.
