[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Example 1

[0024] Please refer to Figure 1 and Figure 2 As shown, a raw material screening device for processing artificial boards includes a main body 1. A screening mechanism is provided inside the main body 1. The screening mechanism includes a first screening plate 8 rotatably connected to the main body 1. Sliding columns 7 are provided at both ends of the first screening plate 8. Sliding grooves 6 that cooperate with the sliding columns 7 are provided at both ends of the main body 1. A rotary motor 11 is installed on the rear surface of the main body 1. A first crushing roller 9 that penetrates into the interior of the main body 1 is connected to the output end of the rotary motor 11. A first gear 3 that penetrates into the exterior of the main body 1 is fixed at the end of the first crushing roller 9. An extrusion plate 5 that cooperates with the sliding column 7 is fixed on the front surface of the first gear 3.

[0025] In this embodiment, the rotary motor 11 drives the first gear 3 to rotate through the first crushing roller 9. The rotation of the first gear 3 drives the extrusion plate 5 to rotate. When the extrusion plate 5 rotates, it pushes the sliding column 7 back and forth. The sliding column 7 slides inside the sliding groove 6 of the unit. Under the action of gravity, the sliding column 7 can quickly reset when it is not squeezed by the extrusion plate 5. The sliding column 7 drives the first screening plate 8 to rotate back and forth, which can achieve screening while avoiding the accumulation of raw materials and blockage.

[0026] Example 2

[0027] Please refer toFigure 2 and Figure 3 As shown, the screening mechanism also includes a crushing component for crushing raw materials to improve the utilization rate of wood. The crushing component includes a second crushing roller 10, and the first crushing roller 9 and the second crushing roller 10 are engaged with each other. A second gear 4 that extends through the body 1 is fixed on the front surface of the second crushing roller 10. The second gear 4 meshes with the first gear 3.

[0028] In this embodiment, the first gear 3 and the second gear 4 mesh with each other and rotate relative to each other, thereby realizing the relative rotation between the first crushing roller 9 and the second crushing roller 10. The raw materials that have not been screened fall between the first crushing roller 9 and the second crushing roller 10 and are crushed.

[0029] Example 3

[0030] Please refer to Figure 3 and Figure 4 As shown, the screening mechanism also includes a pushing component for pushing raw materials. The pushing component includes a chain groove 21 located outside the first screening plate 8 and a second transmission wheel 14 located at one end of the main body 1. A transmission rod 22 that penetrates into the chain groove 21 is fixed at one end of the second transmission wheel 14. A sprocket 20 is fixed at the end of the transmission rod 22. A chain 18 is slidably connected inside the chain groove 21. The chain 18 and the sprocket 20 mesh with each other. The transmission rod 22 rotates concentrically with the first screening plate 8. A first transmission wheel 12 that penetrates into the outside of the main body 1 is fixed at one end of the second crushing roller 10. A conveyor belt 13 is wound around the outside of the first transmission wheel 12 and the second transmission wheel 14. A pushing plate 17 is fixed at the top of the chain 18. A deformable rubber pad is provided at the position where the pushing plate 17 contacts the chain. The rubber pad deforms when the pushing plate 17 passes through both sides of the first screening plate 8, thereby facilitating the normal operation of the pushing plate 17.

[0031] In this embodiment, the transmission rod 22 rotates concentrically with the first screening plate 8 to avoid motion interference when the transmission rod 22 and the first screening plate 8 rotate. Under the action of the conveyor belt 13, the first transmission wheel 12 drives the second transmission wheel 14 to rotate. At this time, the second transmission wheel 14 drives the transmission rod 22 to rotate, and the transmission rod 22 drives the sprocket 20 to rotate. The sprocket 20 drives the chain 18 to move, and the chain 18 drives the pusher plate 17 to move. The pusher plate 17 gradually pushes the material on the top of the first screening plate 8 to one side to avoid the material blocking the first screening plate 8.

[0032] Example 4

[0033] Please refer to Figure 3As shown, a first discharge port 15 is provided on one side of the main body 1, and a feed port 2 is provided on one side of the top of the main body 1. A second discharge port 19 is provided on one side of the bottom of the main body 1. A second screening plate 16 is rotatably connected to the bottom of the interior of the main body 1. A connecting rope is provided on one side of the top of the second screening plate 16, and the end of the connecting rope is connected to the bottom of the first screening plate 8.

[0034] In this embodiment, the feed inlet 2 facilitates the entry of raw materials. The raw materials entering the main body 1 are screened by the first screening plate 8. The screened raw materials fall onto the second screening plate 16 and are screened by the second screening plate 16. The screened raw materials fall through the second screening plate 16 and flow out from the second discharge port 19. The unqualified raw materials flow out from the first discharge port 15. At the same time, the connecting rope makes the second screening plate 16 move synchronously with the first screening plate 8 to avoid the second screening plate 16 from being blocked.

[0035] The working principle and usage process of this device are as follows: Raw materials are added through the feed inlet 2. The rotary motor 11 is started, which drives the first gear 3 to rotate through the first crushing roller 9. The rotation of the first gear 3 drives the extrusion plate 5 to rotate. When the extrusion plate 5 rotates, it pushes the sliding column 7 back and forth. The sliding column 7 slides inside the sliding groove 6 of the device. Under the action of gravity, the sliding column 7 can quickly return to its original position when it is not squeezed by the extrusion plate 5. The sliding column 7 drives the first screening plate 8 to rotate back and forth, which can achieve screening while avoiding the accumulation of raw materials and blockage. Under the action of the connecting rope, the second screening plate 16 moves synchronously with the first screening plate 8. The material screened by the first screening plate 8 falls to the top of the second screening plate 16 for screening again. The qualified material falls from the second discharge port 19 after being screened by the second screening plate 16. At the same time, the raw materials that have not passed through the first screening plate 8 fall between the first crushing roller 9 and the second crushing roller 10 for crushing. The crushed material also falls to the top of the second screening plate 16. The unqualified raw materials cannot pass through the second screening plate 16. At this time, the unqualified raw materials flow out from the first discharge port 15.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
