The feeding assembly 30 is fixedly mounted on the roller shaft 20. The roller shaft 20 is connected through the transmission assembly 40. A roller 201 is integrally fixedly mounted on the outer circumference of the roller shaft 20. The roller 201 is located in the frame 10.

[0035] Wherein, the feeding assembly 30 includes:

[0036] A feeding tray 301, wherein a plurality of evenly distributed feeding trays 301 are fixedly mounted on the periphery of the roller 201, and a plurality of movable blocks 302 distributed in a circular array are slidably mounted on the periphery of the feeding tray 301;

[0037] A reciprocating assembly 50, wherein the reciprocating assembly 50 is movably mounted in the frame 10, and the movable block 302 is transmission-connected via the reciprocating assembly 50;

[0038] The transmission assembly 40 includes a gear 401 . The gear 401 is fixedly mounted on one end of the roller shaft 20 . All the gears 401 are connected through a chain 402 .

[0039] When the device is in use, the roller shaft 20 drives the roller 201 connected thereto to rotate synchronously, and the roller 201 drives the feed tray 301 to rotate during the rotation. At the same time, the reciprocating component 50 drives the movable block 302 to move back and forth along the outer circumference of the feed tray 301, so that the feed tray 301 can continuously push the material to move through the movable block 302 during the rotation to prevent the material from getting stuck.

[0040] The front and rear sides of the frame 10 are respectively fixedly installed with inclined support plates 101, and the top surfaces of the support plates 101 are respectively fixedly installed with a plurality of bearing seats 202 corresponding to the roller shafts 20, and both ends of the roller shafts 20 respectively pass through the corresponding bearing seats 202, and the roller shafts 20 are respectively fixedly connected to the inner rings of the corresponding bearing seats 202.
