[0039] It can be understood that the cam intermittent indexer 26, also known as a cam divider, an intermittent divider or a cam indexer, is a precision mechanical device that converts continuous input motion into intermittent output motion through the gapless fit between the cam and the needle inside. The working principle of the cam intermittent indexer 26 is based on the gapless and vertical engagement between the cam and the needle bearing. In the working process, the cam on the input shaft rotates according to the predetermined curve trajectory, and the index plate is in close contact with the cam through the needle bearing. When the cam rotates, the curve segment drives the index plate to perform indexing motion, that is, one or more stations on the index plate rotate. At the straight line segment of the cam, the index plate is stationary and self-locked for positioning, preparing for the next indexing process. In the present embodiment, the use of the cam intermittent indexer 26 facilitates the synchronous relative intermittent rotation of the two turntables 21, meeting the needs of intermittent tea cake pressing; at the same time, the helical wrapping directions of the two worms 24 in the present embodiment are opposite, when the worms 24 rotate, the two side worm gears 23 can rotate synchronously and relatively, thereby facilitating the synchronous relative rotation of the two turntables 21, and facilitating better tea pressing operation.

[0040] It is worth noting that the first motor 27 and the second motor 33 involved in the present embodiment are existing conventional technologies, which will not be described here.

[0041] In specific use, the user first connects the power supply of the first motor 27 and the second motor 33, and the first motor 27 and the second motor 33 start to work. The output shaft of the first motor 27 drives the cam intermittent indexer 26 to operate, and the output shaft of the cam intermittent indexer 26 drives the connecting shaft 25 and the worm 24 to rotate, and the worm 24 drives the worm gear 23 to rotate, and the worm gear 23 drives the transmission shaft 22 and the turntable 21 to rotate. The output shaft of the second motor 33 drives the carrier roller 31 to rotate, and the carrier roller 31 drives the conveyor belt 32 to move. Then the user puts tea into the tea pressing hole 210, when the tea pressing hole 210 loaded with tea moves to the lower side of the pressing rod 281, the piston rod of the electric cylinder 29 drives the movable plate 28 to move downward, the movable plate 28 drives the lug plate 280 and the pressing rod 281 to move downward, and the pressing rod 281 is pressed into the tea pressing hole 210, and the tea is pressed into a cake. With the rotation of the turntable 21, when the tea pressing hole 210 loaded with tea cake moves to the discharge hole 200, the tea cake falls to the top of the conveyor belt 32 under the action of gravity, and the tea cake can be conveyed with the movement of the conveyor belt 32.
