DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0020] Refer to Figures 1-4 , a material head screening mechanism, including a plurality of support legs 1. The tops of the plurality of support legs 1 are fixedly connected with a screening frame 2. A protective cover 14 is provided on the tops of the two screening frames 2. By providing the protective cover 14, it is possible to prevent the material heads from being ejected during the screening process, improving the safety of the device;

[0021] The protective cover 14 is adapted to the screening rack 2. A connecting fixing plate 3 is fixedly connected to the side wall of the screening rack 2. A rotating motor is fixedly connected to the outer side wall of the fixing plate 3. The output end of the rotating motor is fixedly connected to a rotating shaft 4. The rotating shaft 4 is connected to a screening mechanism through a transmission mechanism. The transmission mechanism includes a first transmission wheel fixedly connected to the outer side wall of the rotating shaft 4. A baffle 10 is connected to the side wall of the screening rack 2. A driving shaft 5 is rotatably connected to the side wall of the baffle 10. A second transmission wheel is fixedly sleeved on the outer side wall of the driving shaft 5. The first transmission wheel and the second transmission wheel are connected by a transmission belt 6. The screening mechanism includes a plurality of driven shafts rotatably connected to the side of the baffle 10. The plurality of driven shafts and the driving shaft 5 are connected by synchronous belt drive;

[0022] A plurality of driven shafts and the outer side walls of the driving shaft 5 are fixedly sleeved with screening wheels 12. Among them, the screening wheels 12 are densely arranged. The gaps between the plurality of screening wheels 12 can distinguish the quality of the material heads. Furthermore, the good material heads can leak through the gaps between the screening wheels 12, and the defective products can be screened out;

[0023] A U-shaped protective plate 11 is fixedly connected between the side walls of the baffle 10. The U-shaped protective plate 11 realizes the blocking of the material heads, avoiding the ejection of the material heads from the protective cover 14;

[0025] The specific working principle of the present utility model is as follows:

[0026] In the initial state, the processed material heads enter the screening rack 2 from the feeding funnel 7. A conveyor belt is arranged on the screening rack 2. The working principle of the conveyor belt is prior art and will not be elaborated in detail here. Then the material heads are conveyed. The rotating shaft 4 works to drive the driving shaft 5 to rotate through the transmission belt 6, and then drives the screening wheels 12 to rotate. Since the plurality of screening wheels 12 are densely arranged, the material heads are divided into finished products and defective products. The edges of the defective material heads have protrusions. The gaps between the screening wheels 12 are not enough for the defective products to fall. Furthermore, the defective products will be displaced according to the rotation of the screening wheels 12 and discharged from the guide plate 13. The finished product of the material head will fall through the gaps between the screening wheels 12, and the screening of the material heads can be realized.
