[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 , an automatic feeding device for a feeding tray, comprising a vibration motor 1, the vibration motor 1 is installed inside a casing 2, the casing 2 is installed at one end of a base 3, a feed hopper 4 is installed on the top of the casing 2, the outlet of the feed hopper 4 is connected to the upper middle part of a vibration feeding tray 18 through an inclined platform, and a baffle 11 is installed at one end of the feed hopper 4. When the vibration motor 1 is not working, the material is blocked by the baffle and accumulated on the first inclined platform 15. When the vibration motor 1 is working, the material will fall into the vibration feeding tray 18 along the inclined platform. A fixed rod 10 is installed on one side of the top of the casing 2, and a material discharge sensing mechanism is installed at one end of the fixed rod 10, and the material discharge sensing mechanism is a swinging infrared sensing structure. The infrared sensor 23 of the material discharge sensing mechanism senses the amount of material at the bottom of the vibration feeding tray 18 and swings, thereby transmitting a signal to the control center, thereby controlling the start and stop of the vibration motor 1, so that the material in the feed hopper 4 automatically falls into the vibration feeding tray 18.

[0022] A support seat 5 is installed on one side of the top of the casing 2 and one side of the feed hopper 4. The support seat 5 is fixed on the positioning hole 7 by a hexagonal bolt 6. The position of the support seat 5 can be adjusted by selecting different positioning holes 7. A fixing block 8 is installed on the support seat 5. A positioning bolt 9 is installed on the fixing block 8. The positioning bolt 9 is connected to one end of a fixing rod 10. The positioning bolt presses against the fixing rod 10 to prevent it from shifting when the vibration motor 1 is working. At the same time, the relative position of the fixing rod 10 can be adjusted by the positioning bolt 9. A clamping block 12 is installed on one side of the feed hopper 4. A movable baffle 11 is installed in the clamping block 12. The movable baffle 11 is fixed by a bolt 13. A positioning groove 14 is provided on the movable baffle 11. The baffle 11 can slide up and down inside the clamping block 12. The bolt 13 is installed in the positioning groove 14 to fix the position of the baffle 11. A first inclined platform 15 is installed at the outlet of the feed hopper 4. The first inclined platform 15 is connected to the second inclined platform 17 by a fixing bolt 16. The inclination angle of the second inclined platform 17 is greater than that of the first inclined platform 15.

[0023] The material unloading sensing mechanism includes a fixing rod 10, the other end of the fixing rod 10 extends to above the vibration feeding tray 18, and a positioning block 19 is installed at the other end of the fixing rod 10, the positioning block 19 is connected to the mounting block 22 through a connecting block 20, the connecting block 20 is fixed to the positioning block 19 by bolts, the fixing angle of the connecting block 20 can be adjusted by bolts, and a square groove 21 is opened on the connecting block 20, an infrared sensor 23 is installed on the mounting block 22, an elastic sheet 24 is connected to the infrared sensor 23, a stopper 25 is installed at one end of the elastic sheet 24, and the stopper 25 will vibrate left and right when it contacts the material. At this time, the vibration motor 1 does not work. When the stopper 25 does not contact the material and is blocked, the vibration motor 1 starts to vibrate, and the material falls to the vibration feeding tray 18, and the vibration feeding tray 18 is installed on the support plate 26, and the support plate 26 is installed at the other end of the base 3 by supporting bolts 27.

[0024] During use, the material is first poured into the feed hopper 4, and the material is blocked by the baffle 11 on the first inclined platform 15. When the block 25 no longer vibrates, it means that there is a lack of material in the vibrating feed tray. At this time, the infrared sensor 23 sends a signal to indirectly control the start and stop of the vibration motor 1, so that it starts working. After the vibration motor vibrates, the material breaks through the baffle 11 and falls along the inclined platform into the vibrating feed tray 18.

[0025] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
