Description
Technical Field

[0002] In order to separate particles of different sizes in the mixed material, a screening device is required for separation.
[0003] The screening device can classify materials, remove impurities in materials, and finely divide products. In many production processes, the screening device helps to optimize the overall process flow, improve production efficiency and product quality.
[0004] The existing screening devices use two sets of screening plates of different specifications to screen the materials step by step. When the materials enter the surface of the screening plate from the hopper, the materials are usually poured directly. The materials usually gather in the central area of the screening plate. Therefore, during the screening process, blockage is very likely to occur. The screening plate is also in a static state in the screening equipment. Therefore, during the screening process, it is very likely to be blocked by the materials, resulting in the inability to screen. Therefore, the screening efficiency is low. To solve this problem, we propose a step-by-step screening device that can prevent blocking. Utility Model Content

The disk 62 fixed on the surface of the round rod 63 rotates synchronously on the surface of the fixed plate 64. When the disk 62 performs circular motion, the toggle plate 61 fixed on the surface of the disk 62 can be continuously toggled on the surface of the screening plate 3. In the toggle process, the material dropped on the surface of the screening plate 3 can be flattened to make it more comprehensively distributed on the surface of the screening plate 3. This method can separate materials of different particle sizes more finely and improve the screening accuracy. At the same time, compared with directly setting an inclined filter plate, it can avoid local material accumulation.
[0026] The surface of the fixed frame 5 is provided with a transverse hole 8, and the setting of the transverse hole 8 can ensure the stable movement of the moving block 683. The toggle member 68 includes: a transverse rod 681, one end of which is fixedly mounted on the surface of the fixed rod 67, and the other end of the transverse rod 681 is fixedly mounted on the surface of the flat rod 682, and the surface of the flat rod 682 is in contact with the surface of the protrusion 685, and the protrusion 685 is fixedly mounted on the inner wall of the fixed frame 5. When the transverse rod 681 moves, the flat rod 682 can move laterally in the two groups of protrusions 685. A moving block 683 is fixedly mounted on the surface of the flat rod 682, and the moving block 683 penetrates the fixed frame 5 and is slidably connected to the fixed frame 5. The surface of the moving block 683 is fixedly connected to one end of the spring 684, and the other end of the spring 684 is fixedly mounted on the inner wall of the transverse hole 8. When the moving block 683 moves with the flat rod 682, it can slide under the support of the spring 684. The surface of the flat rod 682 is fixedly mounted with a second rack 686, which meshes with a latch 687, which is fixedly mounted on the surface of the rotating disk 688.

When the rotating rod 72 rotates, the rotating disk 688 and the support disk 73 rotate synchronously. There are two groups of control components 6 and driven components 7, one group of control components 6 and driven components 7 is arranged on the surface of screen plate 1 3, and the other group of control components 6 and driven components 7 is arranged on the surface of screen plate 2 4. The arrangement of two groups of control components 6 and driven components 7 can avoid blockage during the step-by-step screening process.
[0027] In the utility model, when in use, the material to be screened is poured from the feed hopper into the screening device 2. When the material falls on the surface of the screening plate 3, the motor 71 at the bottom of the fixed frame 5 is started, and the output shaft of the motor 71 drives the rotating rod 72 to rotate. The turntable 688 fixed on the surface of the rotating rod 72 rotates synchronously. When the turntable 688 rotates, the latching teeth 687 fixed on the surface of the turntable 688 can contact the rack 2 686. The rack 2 686 is forced to drive the flat rod 682 to move horizontally in the two sets of protrusions 685. When the rod 682 moves, the moving block 683 fixed on the surface of the flat rod 682 is supported by the spring 684 and slides in the horizontal hole 8.

This method can more finely separate materials of different particle sizes and improve the screening accuracy. At the same time, compared with directly setting an inclined filter plate, it can avoid the accumulation of local materials. At the same time, during the rotation of the rotating rod 72, the support plate 73 fixed on the surface of the rotating rod 72 can rotate synchronously, and the knocking rod 74 hinged on the surface of the support plate 73 can perform a circular motion to the surface of the screening plate 3.

This method can improve the screening efficiency of the material and avoid the situation where screening cannot be performed during the screening process. Since the control component 6 and the driven component 7 are provided with two groups, and the other group is provided on the surface of the screening plate 2 4, the surfaces of the screening plate 1 3 and the screening plate 2 4 can be moved and vibrated during the graded screening process to avoid screening blockage. Since the aperture sizes opened on the surfaces of the screening plates 1 3 and 2 4 are different, graded screening can be achieved.
[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
