[0064] ④ After the clamping action of the clamping finger 22 is completed, the controller drives the driving motor 13 to rotate in the opposite direction, so that the groove-shaped beam 12 moves upward to the initial position;

[0065] ⑤ After the groove-shaped crossbeam 12 moves to the initial position, the controller controls the electromagnetic reversing valve to make the telescopic cylinder 25 start to drive the rack 26 to move a certain distance, and then drives the rotating plate 28 to rotate to an angle of 180 degrees with the original position through the gear 27. At this time, the suction nozzle 19 is facing the mold barrel 2;

[0066] ⑥ The controller controls the vacuum generator 17 to stop working, and the label adsorbed on the suction nozzle 19 falls into the mold barrel 2. At this time, the controller controls the electromagnetic reversing valve again to retract the telescopic cylinder 25 to the initial position;

[0067] ⑦ After the telescopic cylinder 25 is retracted, the controller drives the clamping finger 22 to release by controlling the electromagnetic control valve, and the tea leaves clamped by the clamping finger 22 fall into the mold barrel 2 and cover the label;

[0068] ⑧ After the clamping finger 22 completes the loosening action, the controller controls the cake pressing workbench 1 so that the mold barrel 2 continues to slide on the cake pressing workbench 1 to the next processing step.

4. A process for adding labels inside tea cakes. It is characterized in that The device for adding labels inside tea cakes according to any one of claims 1 to 3 is used, and the process is as follows: ① The controller controls the servo motor to rotate a certain number of times, so that the mold barrel (2) slides on the cake pressing workbench (1) until its open end is directly opposite to the cover plate (23) and the suction nozzle (19) is directly opposite to the label through hole (181). At this time, the controller controls the servo motor to stop rotating and the mold barrel (2) stops sliding; ② The controller drives the driving motor (13) to rotate a certain number of revolutions, so that the sliding block (11) drives the groove-shaped beam (12) to move downward a certain distance. During the downward movement of the groove-shaped beam (12), the controller controls the electromagnetic control valve so that the rotary clamping cylinder (21) drives the blade (24) to rotate. During the rotation, the blade (24) flattens the tea leaves in the mold barrel (2). When the groove-shaped beam (12) no longer moves downward, the suction nozzle (19) contacts the label in the label placement box (18), and the blade (24) stops rotating. ③ The controller controls the electromagnetic control valve so that the rotating clamping cylinder (21) drives the clamping fingers (22) to perform a clamping action, and a pair of the clamping fingers (22) clamp a portion of tea leaves. At this time, the controller controls the vacuum generator (17) and the static eliminator (20) to work, and the suction nozzle (19) sucks a label from the label placement box (18); ④ After the clamping action of the clamping finger (22) is completed, the controller drives the driving motor (13) to rotate in the opposite direction, so that the groove-shaped beam (12) moves upward to the initial position; ⑤ After the groove-shaped crossbeam (12) moves to the initial position, the controller controls the electromagnetic reversing valve so that the telescopic cylinder (25) starts to drive the rack (26) to move a certain distance, and then drives the rotating plate (28) to rotate to an angle of 180 degrees with the original position through the gear (27). At this time, the suction nozzle (19) is directly opposite to the mold barrel (2); ⑥ The controller then controls the vacuum generator (17) to stop working, and the label adsorbed on the suction nozzle (19) falls into the mold barrel (2). At this time, the controller again controls the electromagnetic reversing valve to retract the telescopic cylinder (25) to the initial position; ⑦ After the telescopic cylinder (25) is retracted, the controller drives the clamping fingers (22) to release by controlling the electromagnetic control valve, and the tea leaves clamped by the clamping fingers (22) fall into the mold barrel (2) and cover the label; ⑧ After the clamping fingers (22) complete the loosening action, the controller controls the cake pressing workbench (1) so that the mold barrel (2) continues to slide on the cake pressing workbench (1) to the next processing step.
