[0025] like Figure 1 As shown, the present invention proposes a tea kneading device, including a kneading disc 120, a driving device 200, a kneading cylinder fixing seat 150, a kneading cylinder 140, and a rotary motor 110. The kneading cylinder 140 is disposed inside the kneading cylinder fixing seat 150 and is coaxially arranged with the kneading cylinder fixing seat 150. The rotary motor 110 drives the kneading cylinder fixing seat 150 to reciprocate above the kneading disc 120 through a connecting rod structure 130. The driving device 200 is disposed on the kneading cylinder fixing seat 150 and is used to adjust the gap between the kneading cylinder 140 and the kneading disc 120.

[0026] By placing tea leaves in the rolling cylinder 140, the rolling cylinder fixing seat 150 and the rolling cylinder 140 are reciprocated and rotated above the rolling disc 120 by the cooperation of the rotating motor 110 and the connecting rod structure 130, so that the ribs 121 of the rolling disc 120 are pressed against the tea leaves and rolled according to the distribution of the ribs 121. When the rolling is completed, the rolled tea leaves are discharged through the discharge port of the rolling disc 120. The tea leaves that are difficult to remove and are located at the edge of the ribs 121 and below the rolling cylinder 140 are cleaned by driving the rolling cylinder 140 to move upward by the driving device 200. The gap between the rolling cylinder 140 and the ribs 121 of the rolling disc 120 is adjusted by the driving device 200, so as to adjust the rolling effect on the tea leaves when the rolling cylinder 140 rotates.

[0027] The tea leaf rolling device further comprises a rolling machine base 100, and the rolling disc 120 and the rotating motor 110 are fixed on the rolling machine base 100. A guide chute 160 is arranged in the rolling machine base 100, one end of the guide chute 160 is located below the rolling disc 120, and the other end of the guide chute 160 extends out of the rolling machine base 100. When the tea leaf rolling is completed, the rolled tea leaves are discharged through the discharge port of the rolling disc 120 and guided onto the guide chute 160 and discharged, so as to realize the discharging process.

[0028] In combination Figure 2 and Figure 3 As shown in the figure, the driving device 200 comprises a driving motor, a gear 210 and a rack 220. The rack 220 is fixed on the circumferential side of the rolling cylinder 140 and is parallel to the height direction of the rolling cylinder 140. The driving motor is fixed on the rolling cylinder fixing seat 150, the gear 210 is fixed on the output end of the driving motor, and the gear 210 is connected with the rack 220 in meshing.

[0029] The gear 210 is driven to rotate by the driving motor, and the height of the rolling cylinder 140 is adjusted by the meshing action of the gear 210 and the rack 220. Further, the driving device 200 is electrically connected with an external control device, so as to be controlled by the operator conveniently.

[0030] It needs to be further explained that, as shown in the figure, Figure 4 The circumferential side of the rolling cylinder 140 is symmetrically provided with a groove structure 141, the groove structure 141 extends along the height direction of the rolling cylinder 140, and the rack 220 is arranged in one of the groove structures 141.

[0031] Generally, since the rubbing cylinder 140 is in a cylindrical shape, in order to avoid the protrusion of the rack 220, a groove structure 141 is arranged to facilitate the installation of the rack 220. The inner side of the rubbing cylinder fixing seat 150 is provided with a protruding part 151, which is located in another groove structure 141. Through the arrangement of the protruding part 151, during the movement of the rubbing cylinder 140 driven by the driving device 200, the protruding part 151 moves relative to the groove structure 141, thereby ensuring the stability of the rubbing cylinder 140 during the movement.

[0032] Further, the rubbing cylinder 140 is provided with a gland device 142. Through the arrangement of the gland device 142, the tea in the rubbing cylinder 140 can be compacted, so as to ensure the pressure between the tea and the rib bones 121, and further control the rubbing density.

[0033] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
