Therefore, it is of great practical significance to design a feeding mechanism that can feed continuously without stopping and has a wide universality. Summary of the Invention

[0020] The embodiments of the present invention will be elaborated in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0021] As Figure 1-6 shown, a double-layer storage bin mechanism includes a bin body, a material supporting claw mechanism, and a lifting mechanism for the material supporting claws disposed on a base 10. The bin body includes a feeding bin 2 and a pull-out type discharging bin 1 located below the feeding bin 2. The discharging bin 1 is pulled out or pushed into the bin body. The material supporting claw mechanism includes a material supporting claw 3 and a driving mechanism for the material supporting claw. The material supporting claw 3 is respectively connected to the driving mechanism for the material supporting claw and the lifting mechanism for the material supporting claws. The material supporting claw 3 is driven by the lifting mechanism for the material supporting claws to reciprocate vertically along the feeding bin 2 and the discharging bin 1, and the material supporting claw 3 is driven by the driving mechanism for the material supporting claw to extend under the product placed in the discharging bin 1 and lift the product into the feeding bin 2 or pull out from under the product placed in the discharging bin 1.

[0022] The discharging bin 1 can be pulled out from the interior of the bin body, which is convenient for subsequent manual feeding operations. After the manual feeding is completed, the discharging bin 1 is pushed into the bin body. At this time, it does not affect the operation of the feeding bin 2. The size of the discharging bin 1 is adjusted according to the size of the material product, etc., and it is applicable to the feeding of material products of different specifications, with strong practicability.

[0023] A linear guide rail 1-3 for the discharging bin 1 to freely enter and exit the interior of the bin body is provided on the bin body. The slider 1-4 at the bottom of the discharging bin 1 slides along the linear guide rail 1-3 to realize the pulling out or extending of the discharging bin 1 from the interior of the bin body. Other existing pull-out structures can also be used. A slide rail 9 for the vertical reciprocating movement of the lifting connecting plate 5 and the material supporting claw mechanism thereon is also provided on the bin body. The slide rail 9 is a vertical linear guide rail.

[0024] The feeding bin 2 is fixed in the bin body. The material product on the discharging bin 1 is mainly lifted to the feeding bin 2 by the material supporting claw 3 to supply materials to the equipment. After the material enters the feeding bin 2, the discharging bin 1 can be freely pulled out from the interior of the bin body.

[0025] The main function of the material supporting claw 3 is to lift the material pushed into by the discharging bin 1 into the feeding bin 2 through the guiding of the slide rail 9 and the telescopic linear guide rail 3-2 of the cylinder, playing a role in connecting the feeding bin 2 and the discharging bin 1, and realizing fully automatic feeding with a high level of mechanization.

[0026] The lifting mechanism of the material supporting claws includes a servo motor 7, a lead screw 8 and a lifting connecting rod 6, which is mainly responsible for providing the power for the up and down movement of the material supporting claws 3. The servo motor 7 is connected to the lead screw 8. The lead screw 8 is placed perpendicular to the base 10, and the base 10 is placed horizontally on the ground. The lead screw 8 is connected to the lifting connecting rod 6. The lifting connecting rod 6 is inserted into the lifting connecting plate 5 on the material bin body and the two move synchronously. A material supporting claw mechanism is arranged at the top of the lifting connecting plate 5. Driven by the servo motor 7, the lead screw 8 drives the material supporting claws 3 to move vertically along the lead screw 8. More specifically, the servo motor 7 drives the lead screw 8 to rotate, drives the lifting connecting rod 6 to push the lifting connecting plate 5 and the material supporting claw mechanism thereon to move reciprocally vertically along the feeding bin 2 and the discharging bin 1.

[0027] A plurality of grooves adapted to a plurality of L-shaped claws 3-1 arranged at intervals on the material supporting claws 3 are formed on both the feeding bin 2 and the discharging bin 1. The material supporting claws 3 further include a material supporting slide plate for connecting a plurality of L-shaped claws 3-1 together. As a more specific embodiment, the grooves formed on the discharging bin 1 include a plurality of circular grooves 1-1 and square grooves 1-2, and the grooves formed on the feeding bin 2 include a plurality of circular grooves and square grooves 2-1. The circular groove 1-1 and the circular groove are adapted and in corresponding positions, and the square groove 1-2 and the square groove 2-1 are adapted and in corresponding positions. When the discharging bin 1 extends into the material bin body, the grooves on the discharging bin 1 correspond to and are adapted to the grooves on the feeding bin 2 one by one. The L-shaped claws 3-1 of the material supporting claws 3 extend into the grooves. Driven by the servo motor 7, the material supporting claws 3 move reciprocally vertically along the grooves on the feeding bin 2 and the discharging bin 1 in the defined direction of the slide rail 9.

[0028] The driving mechanism of the material supporting claws includes a driving cylinder 4 and a cylinder telescopic linear guide rail 3-2. The driving cylinder 4 is connected to the material supporting claws 3. There is relative movement between the material supporting claws 3 and the cylinder telescopic linear guide rail 3-2. The driving cylinder 4 drives the material supporting claws 3 to extend under the products placed in the discharging bin 1 or withdraw from under the products placed in the discharging bin 1 along the defined direction of the cylinder telescopic linear guide rail 3-2.

[0029] A first cushioning plate 1-1 is selectively arranged on the inner side of the bottom of the discharging bin 1, and a second cushioning plate 2-1 is selectively arranged on the inner side of the bottom of the feeding bin 2. When the product is too large and relatively thin, the central part of the material product will be deformed and sag after being lifted. The first cushioning plate 1-1 and the second cushioning plate 2-1 are used to increase the strength of the product stack and avoid deformation and sag.

[0030] The parts not specifically described in the present invention can adopt the prior art and will not be elaborated here.

[0031] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
