In this way, grab piece 41 can move horizontally to the upper side of material frame 20 under the driving of third driving part 42, and align with the material to be grabbed. Fourth driving part 43 is responsible for driving grab piece 41 to move along the vertical direction. When grab piece 41 moves horizontally to the appropriate position, fourth driving part 43 drives grab piece 41 to move downward into hopper 21 and firmly grab the material. After completing the grabbing, fourth driving part 43 drives grab piece 41 to move upward to take the material out of hopper 21. Through the cooperation of third driving part 42 and fourth driving part 43, grab piece 41 can move flexibly in the horizontal direction and the vertical direction to realize accurate grabbing and conveying of the material. This design not only improves the automation degree of the feeding mechanism, but also ensures accurate grabbing and efficient conveying of the material.

[0048] Referring to Figures 1 to 2 In some embodiments of the utility model, grab piece 41 is a suction cup. When third driving part 42 and fourth driving part 43 cooperate to move the suction cup above the material and align, the suction cup will descend and contact the surface of the material. Then, through the corresponding negative pressure generating device (such as a vacuum pump, etc.), negative pressure is generated in the suction cup, so that the suction cup tightly adsorbs the material. Next, fourth driving part 43 drives the suction cup to move upward, takes the material out of hopper 21, and conveys it to the next process for processing.

[0049] Referring to Figures 1 to 4In some embodiments of the present utility model, the shape of the material supporting plate 32 matches the shape of the cross section of the material bin 21. In the material feeding mechanism of the present utility model, the shape of the material supporting plate 32 is designed to match the shape of the cross section of the material bin 21. The material bin 21 is a space for storing materials, and the shape of its cross section may vary depending on the type of material, which can be rectangular, circular or other shapes. In order to ensure that the material supporting plate 32 can closely fit the bottom of the material bin 21 and effectively support and lift the material, the shape of the material supporting plate 32 is designed to match the cross section of the material bin 21. For example, if the cross section of the material bin 21 is rectangular, the material supporting plate 32 will also be designed to be rectangular, and its size will be adapted to the size of the bottom of the material bin 21 to ensure that the material supporting plate 32 can completely cover the bottom of the material bin 21 and provide stable support. This matching design not only improves the fit between the material supporting plate 32 and the material bin 21, but also ensures the stability and accuracy of the material during lifting, avoiding the tilting or falling of the material due to the mismatch of the supporting plate shape.

[0050] Referring to Figures 1 to 2 In some embodiments of the present utility model, two material frames 20 are provided, and the two material frames 20 are arranged in a spaced manner along the first horizontal direction, and one of the material frames 20 can slide on the rack 10 along the second horizontal direction.

Among them, one material frame 20 is specially designed to slide on the rack 10 along the second horizontal direction. The other material frame 20 can be fixed on the rack 10. For example, during production, when a group of materials is consumed or needs to be replaced, the material frame 20 can be slid to leave the feeding position, and then another prepared material frame 20 is slid to the feeding position to continue the feeding operation. This design not only improves the flexibility of the feeding mechanism, but also facilitates the replacement and replenishment of materials, meeting the needs of continuous and efficient production.

[0052] Of course, it should be noted that in some embodiments, three material frames 20 can also be provided, and the material frames 20 on both sides can be movably arranged on the rack 10.
