The working principle of the utility model is as follows:

in operation, the first motor 7 and the second motor 28 are turned on to feed tea leaves to be processed from the feed hopper 27. The second motor 28 drives the third rotating shaft 29 to rotate, the third rotating shaft 29 drives the helical blade 30 to rotate, and the tea leaves are preliminarily extruded and kneaded under the action of the helical blade 30, are gradually conveyed to the feeding pipe 31 and enter the rolling and cutting box 1. Firstly enters a gap formed by the hobbing lining plate 5, the knife roller 3 and the cutter 4, and the first motor 7 drives the knife roller 3 and the cutter 4 to rotate, so that the entering tea leaves are hobbing. The rolled tea leaves fall on the first filter screen 6, the tea leaves meeting the size requirement fall, and the tea leaves which are not fully cut are intercepted on the first filter screen 6 and are rolled and cut again. The cut crushed leaves fall on the second filter screen 23 and slide down on the material guide plate 9 along the second filter screen 23 to enter the next process. Most of the chippings generated during the hobbing process fall into the lower broken blade storage box 25 through the meshes of the second filter screen 23 to be collected, so that the chippings are prevented from entering the next process. The cut broken leaves slide into a gap between the arc-shaped plate 12 and the kneading roller 14 along the material guide plate 9, and the first motor 7 drives the second rotating shaft 13 to rotate through the conveyor belt component, so that the kneading roller 14 is driven to rotate, and the tea leaves are kneaded. The kneaded tea leaves fall onto the third sieve 16, and are sieved. Tea particles meeting the size requirement can be discharged through the third filter screen 16 and the discharge pipe 21. The larger tea particles are intercepted above the third filter 16, and when more tea particles are piled up, the door 33 can be opened to take out the tea particles.
