[0033] In this embodiment, the structure is simple, the design is reasonable, and the operation is convenient. It realizes the integration of feeding, uniform feeding, and arrangement into one device. By setting the inner liner 22 of the feeding cup and the outer shell 21 of the feeding cup, the material inside the outer shell 21 can be evenly dispersed in a ring shape, avoiding the accumulation of material in a local area. At the same time, in conjunction with the lifting mechanism 3 and the top column receiving part 1, the material can be automatically and evenly fed, saving manual operation and improving feeding efficiency. It is not affected by manual operation and solves the urgent need for uniform feeding in automated production.

The large-diameter end of the first frustum section 212 is integrally connected to the cylindrical section 211, and the small-diameter end of the first frustum section 212 is provided with a discharge port. The upper opening of the cylindrical section 211 serves as a discharge port.

[0037] like Figure 5 As shown, in the above embodiment, preferably, the inner liner 22 of the material cup includes a conical section 221, a cylindrical section 222, and a second frustum section 223 arranged sequentially from top to bottom. The large-diameter end of the second frustum section 223 is integrally connected to the bottom end of the cylindrical section 222. The conical section 221 is used to evenly distribute the material into the outer shell 21 of the material cup. The bottom end of the cylindrical section 222 is tightly fitted with the side wall of the first frustum section 212. An annular storage space is formed between the cylindrical section 222 and the first frustum section 212. The second frustum section 223 cooperates with the first frustum section 212 to prevent material leakage.

[0038] In the above embodiment, preferably, the outer diameter of the small diameter end of the second frustum section 223 is adapted to the inner diameter of the discharge port 213 of the first frustum section 212; in this embodiment, in order to achieve the guiding effect on the top post 12, the end of the small diameter end of the second frustum section 223 is provided with an inner groove 224 corresponding to the position of the top post 12, and the inner groove 224 is used for the insertion of the top post 12.

[0039] like Figure 1-2 As shown, in the above embodiment, preferably, the lifting mechanism 3 includes a linear module 32 and a mounting plate 31, with the linear module 32 mounted vertically on the mounting plate 31; the cup shell 21 is connected to the moving part 321 of the linear module 32 via a gripper mechanism 4. In this embodiment, the moving part 321 of the linear module 32 is a slider of the linear module 32; the linear module 8 is driven by a servo motor and a coupling to drive the ball screw to reciprocate. Since the linear module 8 is an existing design, it will not be described in detail here.

[0040] In the above embodiment, preferably, the gripper mechanism 4 includes a pneumatic gripper 42 and a gripper connecting plate 41; the fixed end of the pneumatic gripper 42 is installed on one end of the gripper connecting plate 41, and the other end of the gripper connecting plate 41 is fixedly installed on the moving part 321 of the linear module 32; the gripping ends of the pneumatic gripper 42 are respectively gripped on both sides of the cup shell 21. In this embodiment, a gripping block 43 is provided on both sides of the gripping end of the pneumatic gripper 42 corresponding to the cup shell 21. The gripping surface of the gripping block 43 on the side near the cup shell 21 is arc-shaped, and the arc of the gripping surface is adapted to the arc of the cup shell 21.

[0041] In the above embodiments, preferably, the dimensions of the outer shell 21 and the inner liner 22 of the cup can be adjusted according to the actual situation.

[0042] How to use this embodiment:

[0043] 1) The granular material to be fed is loaded into the material cup shell 21 through the top opening. During the loading process, the material will first come into contact with the conical section 221 of the material cup liner 22. The conical section 221 will evenly distribute the material to the surrounding area, so that the material is initially evenly distributed in the material cup shell 21 and gradually accumulates in the cylindrical section 211 and the first frustum section 212 of the material cup shell 21. Some of the material enters the annular storage space between the cylindrical section 222 and the first frustum section 212.

[0044] 2) Activate the lifting mechanism 3. By controlling the linear module 32 to activate the lifting mechanism 3, the material cup 2 installed on the moving part 321 of the linear module 32 begins to descend. When the material cup 2 moves into position, the top post 12 of the top post receiving part 1 will insert into the inner groove 224 at the bottom of the material cup liner 22. As the material cup 2 continues to move downward, the top post 12 pushes the material cup liner 22 upward, thereby opening the discharge port 213 at the bottom of the material cup shell 21.

[0045] 3) Under the action of gravity, the material inside the outer shell 21 of the material cup falls into the receiving trough of the receiving plate 11 through the opened discharge port 213. Due to the uniform distribution of the material by the inner lining 22 of the material cup and the consistent opening of the discharge port 213, the material can fall evenly into the receiving trough;

[0046] 4) After the material is fed, the lifting mechanism 3 lifts the cup section 2 upwards, so that the cup liner 22 returns to its initial position. At this time, the cup liner 22 seals the discharge port 213 of the cup shell 21 again by gravity, in preparation for the next feeding operation.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
