[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] like Figure 1-4 As shown, this utility model provides a color powder screening and grading machine, including a sorting box 1. A feed inlet 2 is fixedly connected to one end of the top of the sorting box 1. Several relatively inclined screening mesh belts 4 are arranged inside the sorting box 1. The screening mesh belts 4 are arranged in a stepped manner, and the distance between every two screening mesh belts 4 is greater than the height of the feeding belt 6. Feeding ports 9 that cooperate with the feeding belt 6 are opened on both sides of the sorting box 1. A support plate 10 is fixed to the bottom surface of the sorting box 1 inside the side of the bottom feeding port 9. The side of the support plate 10 away from the feeding port 9 is flush with the bottom outer surface of the bottom of the bottom screening mesh belt 4. The two screen belts 4 are rotatably connected to the inside of each screen belt 4. The two conveyor rollers 3 are rotatably connected to the inside of the sorting box 1. Each screen belt 4 is provided with a feeding belt 6 below it. One end of each feeding belt 6 extends to the outside of the sorting box 1. Both ends of the feeding belt 6 extending to the outside of the sorting box 1 are provided with support side plates 8. The support side plates 8 are fixed to the side wall of the sorting box 1. Each feeding belt 6 is rotatably connected to the inside of each screen belt 4. The two conveyor rollers 7 in each group are rotatably connected to the side wall of the sorting box 1 and the support side plate 8 respectively through bearings.

[0023] The specific settings and functions of this embodiment are described below: A vibration generator 15 is provided on the front side of the sorting box 1. A vibration guide rod 16 is provided on the top surface of each screening mesh belt 4. Each vibration guide rod 16 is connected to the output end of the vibration generator 15. The mesh size of the screening mesh belt 4 gradually increases from top to bottom. A guide plate 5 is provided at the top of each screening mesh belt 4. Each guide plate 5 is fixed on the inner side wall of the sorting box 1. Each guide plate 5 is set to be inclined in the same direction as the screening mesh belt 4. In use, the vibration generator 15 is driven to vibrate by the vibration guide rod 16, which in turn drives the screening mesh belt 4 to vibrate. This makes the screening mesh belt 4 faster and more thorough when screening materials. The guide plate 5 guides the materials so that when the color powder material falls, it falls onto the top surface of the screening mesh belt 4.

[0024] Example 2

[0025] like Figure 1-4 As shown, a gear 12 is provided on the outside of the sorting box 1 behind each conveyor roller 1 3 and conveyor roller 2 7. The front end of each gear 12 rotates through into the interior of the sorting box 1. One end of each gear 12 extending into the interior of the sorting box 1 is fixed to the rear end of each conveyor roller 1 3 and conveyor roller 2 7. The two gears 12 on the rear side of each set of conveyor roller 1 3 and conveyor roller 2 7 mesh with each other. A servo motor 11 is provided behind the uppermost conveyor roller 1 3. The output end of the servo motor 11 is fixed on the uppermost gear 12. Each layer of conveyor roller 2 7 and the rear side wall of the gear 12 of the adjacent lower layer of conveyor roller 1 3 are fixed with a pulley 13. The two adjacent pulleys 13 are connected by a transmission belt 14.

[0026] The overall effect of this embodiment is that, through the cooperation of gear 12, pulley 13 and transmission belt 14, the servo motor 11 can drive all screening mesh belts 4 and feeding belts 6 to run, making the classifier easier and more labor-saving to control during operation.

[0027] The operating method and working principle of this device are as follows: When it is necessary to sort the color powder, first turn on the servo motor 11, so that the servo motor 11 drives the gear 12 to rotate. The gear 12 drives the pulley 13 to rotate. The pulley 13 drives the conveyor roller 3 of the next screening screen belt 4 to rotate through the transmission belt 14. When the conveyor roller 3 rotates, it drives another conveyor roller 3 inside the screening screen belt 4 to rotate. The other conveyor roller 3 continues to drive the pulley 13 to rotate, thus driving the entire screening screen belt 4 to move. At the same time, the conveyor roller 3 drives the other conveyor roller 4 through the gear 12 to rotate. The lower conveyor rollers 7 rotate in the opposite direction, causing the feed belts 6 below each screening mesh belt 4 to move in the opposite direction, thereby driving the raw materials to move in a Z-shape on the screening mesh belt 4. The raw materials are poured into the sorting box 1 through the feed inlet 2 and fall onto the uppermost screening mesh belt 4. Driven by the screening mesh belt 4, the raw materials gradually move to the lower layers. During the movement, the raw materials are screened and graded. The graded raw materials fall onto each layer of feed belt 6 and are then carried out by the feed belt 6. At the same time, the vibration generator 15 runs, driving the vibration guide rod 16 to vibrate, thereby assisting the screening mesh belt 4 in vibration screening.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
