[0028] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2 As shown, the weighing assembly includes a weighing sensor 32 and a storage container 33. The weighing sensor 32 is arranged on the mounting plate 31. The weighing sensor 32 is located on one side of the placement slot 34 and a storage container 33 for placing tea packaging cans is arranged on the weighing sensor 32. One of the storage containers 33 is located directly below the discharge port 11. It should be noted that the storage container 33 is adapted to the size of the tea packaging can. The weighing assembly can realize automatic real-time weighing of the weight of the tea leaves filled in the tea packaging can, and cooperates with the emergency stop solenoid valve 12 and the chain conveyor belt 3 to complete the assembly line filling and weighing process.

[0029] It should be noted that the emergency stop solenoid valve 12, the chain conveyor belt 3, the vibration motor 24, the electric cylinder 42, the electric push rod 43, the air pump 45 and the weighing sensor 32 are all electrically connected to the controller, which is not shown in the figure.

[0030] The workflow of this utility model:

[0031] First, tea leaves are uniformly added into the screening box through the feed hopper 21. When the tea leaves enter the screening box, the controller controls the vibration motor 24 to work. At this time, the tea leaves can be vibrated and screened on the curved screen, and then the tea stems and residues in the tea leaves are separated from the tea leaves. The tea stems and residues pass through the curved filter screen 26 and finally pass through the discharge port 22 and the discharge pipe 23 to the waste bin in sequence. The tea leaves without impurities can move along the bottom of the curved filter screen 26 under the action of the vibration motor 24 and finally flow out of the screening box into the conveying pipe 25 and flow into the injection box 1 along the conveying pipe 25 for storage;

[0032] At the same time, a six-degree-of-freedom robotic arm is used to place a tea packaging can (placed in the storage container 33) and a cover (placed in the placement slot 34) from the starting end of the chain conveyor belt 3 to each conveyor chain plate in turn, and the intermittent conveying rate of the chain conveyor belt 3 is controlled. The six-degree-of-freedom robotic arm, tea packaging cans and covers are not shown in the figure. After the placement is completed, the chain conveyor belt 3 can make a storage container 33 move just below the discharge port 11 every time it moves intermittently. At this time, the controller controls the emergency stop solenoid valve 12 to open, and then starts to deliver the tea bags During the canning process, the weighing sensor 32 can automatically weigh the quality of the tea in real time as the filling proceeds. When the weighing sensor is about to reach a preset weighing value, the weighing sensor 32 will feed back a signal to the controller, and then the controller controls the emergency stop solenoid valve 12 to close. At this time, the quantitative filling process of a tea packaging can is completed, and then the chain conveyor belt 3 moves again to move the next tea packaging can to the bottom of the discharge port 11. The above process is repeated in sequence to realize the automatic weighing and filling process of several tea packaging cans.

[0033] When the tea packaging can is filled with materials, it will eventually move intermittently to the end of the chain conveyor belt 3. In the initial state, the adsorption component is directly above the cover, and then the controller controls the electric push rod 43 to work so that the adsorption component moves down to adsorb the cover, and then the electric push rod 43 drives the cover to move up to a height that is pre-set in the controller and does not affect the horizontal movement of the cover, and then the controller controls the electric cylinder 42 to work so that the cover moves to the top of the tea packaging can and then stops, and then the controller controls the electric push rod to work again to drive the cover to move down to complete the assembly of the cover and the tea packaging can, and after the assembly is completed, the adsorption of the cover is released, and then the adsorption component moves back to the initial position to wait for the next round of packaging; then the packed tea packaging can is subjected to weight at the end of the chain conveyor belt 3 and falls into the collection box to complete the collection;

[0034] Compared with the existing technology, the device can automatically complete the filling and weighing of tea leaves and the capping and packaging after weighing. It does not require manual intervention, reduces labor intensity and makes the process convenient and efficient. At the same time, there is no need for manual discharge of tea stems and residual materials. As the screening proceeds, the discharge of tea stems and residual materials can be automatically completed, thereby improving the degree of automation of tea packaging.
