The tea leaves entering the collecting barrel 201 fall onto the rotating disk 208, and the bottom gear 207 and the rotating disk 208 are driven to rotate by the transmission belt 206, thereby driving the tea leaves to rotate, pushing the tea leaves onto the spiral rail frame 202, and continuously pushing the tea leaves into the pouring bucket 205 along the spiral rail frame 202. When the weight of the tea leaves in the pouring bucket 205 reaches a certain level, the pouring bucket 205 rotates relative to the rotating bucket frame 203, the rotating bucket spring 204 is stretched, and the tea leaves in the pouring bucket 205 are poured into the plastic packaging belt 319.

The upper transmission wheel 317 drives the inner transmission wheel 314 to rotate, thereby driving the transmission belt 329 to rotate, thereby driving the bag holder 318 and the plastic packaging belt 319 to circulate through the transmission belt 329, and the rotation of the inner gear 320 drives the middle gear 321 and the inner lower wheel 322 to rotate, and the middle docking gear 323 is driven to rotate through the middle gear 321, thereby driving the outer lower wheel 324 to rotate, and the rotation directions of the outer lower wheel 324 and the inner lower wheel 322 are opposite, thereby driving the inner heating metal belt 325 and the outer heating metal belt 326 to rotate, and the rotation directions of the inner heating metal belt 325 and the outer heating metal belt 326 are opposite.After the tea leaves in the pouring bucket 205 enter the plastic packaging belt 319, the conveyor belt 329 drives the plastic packaging belt 319 to reach between the active clamp block 308 and the passive clamp block 309. The active clamp block 308 and the passive clamp block 309 slide relative to the frame 304 to initially compress the end of the plastic packaging belt 319. Then the conveyor belt 329 drives the plastic packaging belt 319 to move between the inner heating metal belt 325 and the outer heating metal belt 326. The inner heating metal belt 325 and the outer heating metal belt 326 locally heat-melt the plastic at the mouth of the plastic packaging belt 319 to complete the plastic packaging belt. 319 is sealed, and then the conveyor belt 329 moves to drive the plastic packaging belt 319 to leave the inner heating metal belt 325 and the outer heating metal belt 326, and then the plastic packaging belt 319 is removed from the bag holder 318. The lower motor 301 will pause for a short time each time it rotates. The conveyor belt 329 drives the bag holder 318 and the plastic packaging belt 319 to advance one station each time, and each time the lower motor 301 pauses, the pouring bucket 205 just pours the tea leaves. The rotating bucket spring 204 is a damping spring with a slow rebound speed, ensuring that all the tea leaves in the pouring bucket 205 can be poured into the plastic packaging belt 319.
