[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: a raw material sieving device for paint production, including a sieving device 1. A first feed inlet 101 is arranged on one end face of the sieving device 1, and a slag discharge port 102 is arranged on the rear end face of the sieving device 1. A material guiding plate 2 is fixedly connected to one side of the first feed inlet 101. One side of the material guiding plate 2 passes through the lower end of the first feed inlet 101 and extends into the sieving device 1 and is fixedly connected to a rectangular filter screen 202. A first small vibrator 203 is fixedly connected to the middle of the lower end face of the rectangular filter screen 202. A C-shaped filter screen 3 is connected inside the sieving device 1 on one side of the rectangular filter screen 202. A second feed inlet 301 is arranged on the C-shaped filter screen 3, and a second small vibrator 302 is fixedly connected to the middle of one side of the C-shaped filter screen 3. A screw conveyor blade 4 is rotatably connected inside the C-shaped filter screen 3. A driving device 5 for driving the screw conveyor blade 4 to rotate is fixedly arranged on the front end face of the sieving device 1. A slag box 6 is detachably and fixedly connected to the rear end of the slag discharge port 102.

[0024] Furthermore, a material guiding cavity 103 is arranged inside the sieving device 1 below the rectangular filter screen 202 and the C-shaped filter screen 3. A discharge port 104 is fixedly arranged at the lower end of the material guiding cavity 103. The raw material powder that meets the particle size requirements after being filtered by the rectangular filter screen 202 and the C-shaped filter screen 3 is discharged from the discharge port 104 through the material guiding cavity 103.

[0025] Further, both the front and rear sections of the material guiding plate 2 are fixedly connected with angled baffle plates 201 on the outer side of the sieving device 1. One side of the rectangular filter screen 202 is fixedly connected to the lower end of the second feeding port 301 of the C-shaped filter screen 3. The angled baffle plates 201 are used to block the ground raw materials, causing the raw materials to enter the rectangular filter screen 202 from the first feeding port 101 through the material guiding plate 2. The rectangular filter screen 202 is used to initially filter the ground raw materials. The first small vibrator 203 drives the rectangular filter screen 202 to vibrate, accelerating the filtering process, enabling the vast majority of the raw materials meeting the particle size requirements to fall into the material guiding cavity 103 after being filtered by the rectangular filter screen 202. The particulate raw materials that do not meet the particle size requirements are on the inclined rectangular filter screen 202 and roll into the interior of the C-shaped filter screen 3 by means of vibration.

[0026] Further, the front end of the C-shaped filter screen 3 is fixedly connected to the front end face inside the sieving device 1, and the rear end of the C-shaped filter screen 3 is fixedly connected to the edge of the slag discharge port 102. The second small vibrator 302 drives the C-shaped filter screen 3 to vibrate to separate the particulate raw materials that do not meet the particle size requirements and the powdered raw materials adhering to the particles, enabling the powdered raw materials meeting the requirements to fall into the interior of the material guiding cavity 103 after being filtered by the C-shaped filter screen 3, thus achieving full screening of the ground raw materials.

[0027] Further, a rotating shaft 401 is fixedly connected to the middle of the spiral conveying blade 4. A driving motor 501 is fixedly arranged inside the driving device 5. The rear end of the rotating shaft 401 extends into the driving device 5 and is fixedly connected to the output shaft of the driving motor 501. The driving motor 501 drives the rotating shaft 401 to rotate, thereby driving the spiral conveying blade 4 to rotate, so that when the spiral conveying blade 4 rotates, it conveys the particulate raw materials that do not meet the particle size requirements inside the C-shaped filter screen 3 towards the slag discharge port 102.

[0028] Further, a third feeding port 601 is provided on the front end face of the slag box 6, and the third feeding port 601 communicates with the rear end of the slag discharge port 102.

[0029] Further, the rear end of the spiral conveying blade 4 passes through the third feeding port 601 and extends into the slag box 6, enabling the particulate raw materials meeting the particle size requirements to enter the slag box 6 for collection after being conveyed by the spiral conveying blade 4, which is convenient for re-grinding.

[0030] Working principle: During use, first, the ground raw materials enter the sieving device 1 through the first feed inlet 101, and are guided and dispersed on the rectangular filter screen 202 by the guide plate 2. The rectangular filter screen 202 serves as the primary filtering layer. After the first small vibrator 203 installed at its lower end is started, it drives the rectangular filter screen 202 to vibrate, accelerating the filtering process. The raw material powder meeting the particle size requirements passes through the rectangular filter screen 202 and falls into the lower material guide cavity 103, and finally is discharged from the discharge port 104. The granular raw materials not meeting the particle size requirements roll along the inclined rectangular filter screen 202 under the vibration action and enter the second feed inlet 301 of the C-shaped filter screen 3. The C-shaped filter screen 3 serves as the secondary filtering layer. After the second small vibrator 302 installed on it is started, it further vibrates and screens the granular raw materials not meeting the particle size requirements and the powder raw materials attached thereto. The powder meeting the particle size requirements passes through the C-shaped filter screen 3 again and falls into the material guide cavity 103, achieving full screening. At the same time, the spiral conveyor blade 4 located inside the C-shaped filter screen 3 rotates under the drive of the drive device 5. The drive motor 501 in the drive device 5 drives the spiral conveyor blade 4 to rotate through the rotating shaft 401, thereby conveying the remaining granular raw materials not meeting the particle size requirements inside the C-shaped filter screen 3 towards the slag discharge port 102. These granular raw materials finally enter the detachably connected slag box 6 through the slag discharge port 102 for collection for subsequent re-grinding treatment.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
