[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A stepped track automatic feeding device includes: a vibrating bowl and a feeding track formed in the vibrating bowl. A current-limiting screening structure, a secondary screening structure, and a longitudinal and transverse screening structure are sequentially arranged along the feeding direction of the feeding track. The secondary screening structure includes a step portion arranged in a fault type with the discharge end of the feeding track, and a guiding portion arranged in a climbing type from the step portion to the discharge end of the longitudinal and transverse screening structure.

[0013] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is made in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0014] Please refer to Figure 1 , this embodiment provides a stepped track automatic feeding device, which includes a vibrating tray 10. A feeding track 101 arranged in a spiral manner is formed in the vibrating tray 10. A current-limiting screening structure 20, a secondary screening structure 30 and a longitudinal and transverse screening structure 40 are sequentially arranged along the feeding direction of the feeding track 101. By setting the current-limiting screening structure 20, the secondary screening structure 30 and the longitudinal and transverse screening structure 40, the vibrating tray 10 can be used for feeding materials that are prone to agglomeration and stacking, and the phenomena of material jamming and stacking can be eliminated.

[0015] In this embodiment, please refer to Figure 2, the current-limiting and screening structure 20 is mainly used for current limiting, enabling a single material to pass through the feeding track 101 and conducting a primary screening. The stacked and irregularly moving materials are pushed back into the vibrating disk 10 for re-conveying. The current-limiting and screening structure 20 includes an adjusting block 201 and an adjusting baffle 202. An adjusting opening 102 is provided on the vibrating disk 10. An L-shaped adjusting plate 203 is provided on the outer side wall on one side of the adjusting opening 102. Adjusting grooves are provided at both ends of the L-shaped adjusting plate 203. The adjusting block 201 is fixed to one end of the L-shaped adjusting plate 203, and one end of the adjusting block 201 passes through the adjusting opening 102 and extends into the vibrating disk 10. By providing two adjusting grooves on the L-shaped adjusting plate 203, the position of the L-shaped adjusting plate 203 can be adjusted, and the length of the adjusting block 201 passing through the adjusting opening 102 can also be adjusted to achieve the adjustment of the left-right and front-back positions of the adjusting block 201. One end of the adjusting baffle 202 has a Z-shaped bend. The Z-shaped bend passes through the inside of the vibrating disk 10 and extends to the outside of the vibrating disk 10, and the Z-shaped bend is fixed outside the vibrating disk 10 by a handwheel screw. The adjusting baffle 202 extends along the conveying direction of the feeding track 101 to the adjusting block 201, so that the rear end surface of the adjusting baffle 202 abuts against the adjusting block 201. By adjusting the extended length of the adjusting block 201, the distance between the adjusting baffle 202 and the feeding track 101 is further adjusted to enable a single material to flow through the feeding track 101.

[0016] After the materials pass through the first screening, they are conveyed to the secondary screening structure 30 through the feeding track 101. The secondary screening structure 30 conducts a secondary screening on the materials to disperse the grouped and stacked materials. Please refer to Figure 2 , the secondary screening structure 30 includes a step portion 301 arranged in a fault manner with the discharging end of the feeding track 101 and a guiding portion 302 arranged in a ramped manner from the step portion 301 to the discharging end of the longitudinal and transverse screening structure 40. A transverse material dropping portion 303 and a longitudinal material dropping portion 304 for cooperating with the longitudinal and transverse screening structure 40 to screen materials are further provided on the guiding portion 302. By utilizing the step portion 301 of the secondary screening structure 30, the object drops from the step portion 301 to the guiding portion 302 to shake and disperse the stacked materials, thereby dispersing the materials.

[0017] In this embodiment, in order to increase the flow rate of the materials on the guiding portion 302, a speed-up blowing pipe 50 connected to the air source through a hose is provided on the side wall of the vibrating disk 10. After the speed-up blowing pipe 50 is ventilated, the flow rate of the materials on the guiding portion 302 is increased by blowing. In addition, in this embodiment, the transverse material dropping portion 303 and the longitudinal material dropping portion 304 are respectively a transverse material dropping opening and a longitudinal material dropping opening.

[0018] The materials falling from the step portion 301 flow through the longitudinal and transverse screening structure 40 through the guiding portion 302. Please refer to Figure 3, the vertical and horizontal screening structure 40 includes adjusting plates 401 respectively provided at the horizontal blanking port and the vertical blanking port for adjusting the sizes of the horizontal blanking port and the vertical blanking port, and scraping plates 402 provided at the rear sides of the horizontal blanking port and the vertical blanking port. The scraping plates 402 are mainly used to scrape the materials stacked horizontally and vertically into the vibrating disk 10 to be redispersed. When the vertical materials flow through the adjusting plate 401, one end of the materials does not contact the adjusting plate 401. Due to the lack of support of the adjusting plate 401 at one end of the materials under the action of gravity, the materials fall from the vertical blanking port and flow back into the vibrating disk 10; similarly, when the horizontal materials flow through the adjusting plate 401, one end of the materials does not contact the adjusting plate 401. Due to the lack of support of the adjusting plate 401 at one end of the materials under the action of gravity, the materials fall from the horizontal blanking port and flow back into the vibrating disk 10.

[0019] In addition, in some embodiments, a photoelectric sensor 60 for detecting whether the vibrating disk 10 receives materials normally is provided above the horizontal blanking port. A blowing pipe passing through the vibrating disk 10 and connected to an external air source through a hose is provided on one side of the adjusting plate 401 of the horizontal blanking port. A counter electrically connected to the photoelectric sensor 60 is also provided on the side of the photoelectric sensor 60. When the materials pass through the photoelectric sensor 60, the photoelectric sensor 60 senses the materials, causing the counter to make corresponding statistics. After the counter counts the number of materials, when the discharge amount of the materials reaches a preset value, the blowing pipe blows air to blow the excess materials on the adjusting plate 401 back into the vibrating disk 10.

[0020] In summary, through the adjustment of the baffle 202, the stacked materials are initially screened. Through the step for secondary screening to disperse the materials by object dropping, and through the scraping plate and the adjusting plate 401 for tertiary screening, the materials stacked horizontally and vertically can be scraped into the vibrating disk to be redispersed, ensuring that only one material passes through the vibrating disk horizontally and vertically, eliminating the phenomena of material jamming and stacking, and ensuring the production efficiency of the equipment.

[0021] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
