Example Embodiment

[0028] In the following, the present invention will be further described in conjunction with the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .

[0029] See figure 1 , figure 2 as well as Figure 4 , Shows a screening device according to a preferred embodiment of the present invention. The screening device is used for screening materials. The materials have a large outer diameter end and a small outer diameter end stacked in sequence. The screening device of the present invention is used for material Screening mainly includes the following steps: feeding-filtering materials that are not upright-filtering materials with a large outer diameter end facing upwards. After screening, materials with a large outer diameter end facing downwards can be transported out, while those with a large outer diameter facing upwards The material is returne...

Abstract

The invention discloses a screening device. The screening device comprises a material box, a vibrator, material rail and a feeding mechanism; the material rail is built between the material box and the vibrator and provided with a first conveying channel; the feeding mechanism is used for conveying materials in a material cavity to the first end of the material rail; the feeding mechanism comprises a linear driving part and a feeding part; the first end of the feeding part is in transmission connection with an output shaft of the linear driving part; at least the second end of the feeding partextends into the material cavity; the second end of the feeding part is provided with a feeding surface; and the feeding part can be driven by the linear driving part to perform reciprocating linearmovement, and thus the feeding surface can extend into a material pile in the material cavity, or the feeding surface can ascend so that the feeding surface and the top surface of the first end of thematerial rail are located on the same horizontal plane or the feeding surface is higher than the top surface of the first end of the material rail. By means of the screening device, the phenomenon that the materials are stuck can be avoided, conveying is smooth, the screening efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a screening device. Background technique [0002] Screening devices are generally used to screen granular materials, and are applicable to a wide range of industries, such as chemical, ceramic, food, machinery, electronics and other industries. The screening device is used to filter and screen materials in advance to be able to screen out qualified, Applicable materials, easy to enter the next process. [0003] In the prior art, in order to automatically and accurately rivet the rivets on the desired product, it is necessary to sort the rivets in advance through the screening device in such a way that one end of the splined teeth (gear teeth) faces down, and then pass through the The material rail connects the screening device with the riveting device for riveting the rivet on the product, so that the rivet with the serrated end facing down is transported to the riveting devic...
