[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0016] Specific Embodiment 1: Please refer to Figures 1 to 5 , a feeding and screening mechanism for gasketed screws 4 in this embodiment includes a discharge guide rail 1. One end of the discharge guide rail 1 is communicated with a vibrating bowl. The discharge guide rail 1 is composed of two discharge plates in cooperation, namely a first discharge plate 101 and a second discharge plate 102. A material channel 104 is formed between the first discharge plate 101 and the second discharge plate. The gasket of the screw 4 is supported on the top surfaces of the first discharge plate 101 and the second discharge plate 102. At least one notch 103 is provided on the first discharge plate 101 or / and the second discharge plate 102. In this embodiment, notches 103 are provided on both the first discharge plate 101 and the second discharge plate 102. The two notches 103 are distributed in the front and rear of the discharge guide rail 1. The notch 103 is communicated with the material channel 104. A blanking device 2 is installed on the notch 103 and contacts the head 401 of the screw 4 in the material channel 104.

[0017] The first discharge plate 101 is provided with a notch 103. The ejector device 2 includes an ejector plate 201 and a support block 202. The ejector plate 201 is adjustably installed above the support block 202, and the support block 202 is adjustably installed with the first discharge plate 101. One end of the ejector plate 201 contacts the screw 4 in the material channel 104 above the material channel 104. When the screw 4 is conveyed from the vibrating bowl to the discharge guide rail 1 and reaches the position of the notch 103, if the screw 4 does not have a gasket, the screw 4 will fall below the notch 103 due to the lack of support from the gasket. An aggregate box can be placed under the notch 103 to collect defective products.

[0018] At least one first mounting hole 201-1 is provided on the ejector plate 201, and at least one second mounting hole 202-1 is provided on the support block 202 for installation and connection with the first discharge plate 101. Both the first mounting hole 201-1 and the second mounting hole 202-1 are long holes. The position of the ejector plate 201 in the material channel 104 can be appropriately adjusted according to the first mounting hole 201-1 and the second mounting hole 202-1.

[0019] In addition, in the present application, a material guiding device 3 is provided between the two groups of ejector devices 2. The material guiding device 3 includes a fixing strip 302 and a material guiding rod 301. The material guiding rod 301 is fixed above the fixing strip 302 and above the material channel 104. The fixing strip 302 is installed on the first discharge plate 101 or the second discharge plate 102. A third mounting hole 302-1 is provided below the fixing strip 302, and the third mounting hole 302-1 is a long hole. The material guiding rod 301 is used to correct the screws 4 that are not completely placed in the material channel 104 on the material channel 104, so that the screws 4 are conveyed in a vertical direction.
