[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] This embodiment provides a multifunctional automatic metering, weighing and packaging device for tea. As Figures 1 - 5 shown, the multifunctional automatic metering, weighing and packaging device for tea includes a feeding mechanism 1 for controlling the tea feeding, a metering mechanism 2 arranged at the outlet end of the feeding mechanism 1 for metering and pouring the tea, a conveying mechanism 3 for conveying the packaging bags arranged on one side of the metering mechanism 2 where the tea is poured, and a vacuum packaging mechanism 4 for sealing the packaging bags arranged above the conveying mechanism 3.

[0030] The conveying mechanism 3 includes a packaging bag conveyor belt 31, a first conveying motor 32 fixedly installed on the side of the packaging bag conveyor belt 31 for driving the operation of the packaging bag conveyor belt 31, and guiding rods 33 symmetrically arranged above the packaging bag conveyor belt 31 for limiting the packaging bags and guiding the openings of the packaged bags to gradually close. The gap between the two guiding rods 33 gradually narrows.

[0031] The vacuum packaging mechanism 4 includes clamping conveyor belts 41 symmetrically arranged at the ends of the guiding rods 33 for clamping the bag mouths of the packaging bags, a fixing frame 45 rotatably connected to the clamping conveyor belts 41 for supporting the clamping conveyor belts 41, a second conveying motor 44 fixedly installed on the fixing frame 45 for driving the operation of the clamping conveyor belts 41, heat sealing strips 46 symmetrically arranged below the clamping conveyor belts 41 and moving closer to or away from each other for heat-sealing the bag mouths of the packaging bags, an electric telescopic rod 47 fixedly installed on the side of the fixing frame 45 and with its movable end connected to the side of the heat sealing strips 46 away from each other, and a vacuum pump 49 fixedly installed on the fixing frame 45 and with its air extraction end aligned with the gap between the clamping conveyor belts 41.

[0032] During use, first, the feeding mechanism 1 feeds the tea leaves. The tea leaves fall onto the metering mechanism 2 for automatic weighing. After reaching the predetermined quantity, the feeding mechanism 1 stops feeding. Immediately afterwards, the metering mechanism 2 dumps the measured tea leaves by flipping. At this time, the packaging bag conveyor belt 31 of the conveying mechanism 3 transports empty packaging bags one by one to the lower side of the dumping side of the metering mechanism 2. Subsequently, the packaging bags filled with tea leaves are continuously transported to the vacuum packaging mechanism 4. The clamping conveyor belt 41 runs under the drive of the second conveying motor 44 to clamp the bag mouth of the packaging bag. At this time, the electric telescopic rod 47 pushes the heat sealing strips 46 to approach each other to perform hot pressing and sealing on the bag mouth of the packaging bag. At the same time, the vacuum pump 49 starts to perform vacuum pumping on the inside of the packaging bag through the gap of the clamping conveyor belt 41 to ensure the freshness preservation effect of the tea leaves. After the packaging is completed, the packaging bags are continuously transported to the next process or the collection area; through the multi-functional cooperation of the feeding mechanism, the metering mechanism, the conveying mechanism, and the vacuum packaging mechanism, the entire packaging process realizes full automation from feeding to packaging, greatly reducing manual intervention, improving production efficiency and accuracy. Through automated operation, labor costs and labor requirements are reduced, and the operating costs of the enterprise are lowered.

[0033] Furthermore, on the side where the heat sealing strips 46 are away from each other, a limiting slide rod 48 penetrating the side of the fixed frame 45 is fixedly connected. The limiting slide rod 48 is slidably connected to the fixed frame 45; when the electric telescopic rod 47 pushes the heat sealing strips 46 to approach each other for hot pressing and sealing, the limiting slide rod 48 slides along the guiding groove of the fixed frame 45 to ensure the stability and accuracy of the heat sealing strips 46 during movement.

[0034] Specifically, the feeding mechanism 1 includes a conveying pipe 11, a spiral conveying rod 12 rotatably installed inside the conveying pipe 11, a feeding motor 13 fixedly connected to one end of the conveying pipe 11 and having an output shaft connected to the spiral conveying rod 12, and a first support frame 15 fixedly connected to the outer wall of the conveying pipe 11 for supporting the feeding mechanism 1; the feeding motor 13 drives the spiral conveying rod 12 to rotate inside the conveying pipe 11, thereby transporting the tea leaves from one end of the conveying pipe 11 to the other end and discharging them through the discharge port 111.

[0035] In addition, the metering mechanism 2 includes a second support frame 21, a tipping table 22 hinged to the top of the second support frame 21, a tipping motor 23 fixedly connected to the side of the second support frame 21 and with its output end connected to the rotating shaft of the tipping table 22, an angle sensor 24 fixedly installed on the side of the second support frame 21 away from the tipping motor 23 and connected to the rotating shaft of the tipping table 22, a weighing sensor 25 fixedly connected to the center of the top of the tipping table 22, and a receiving table 26 fixedly connected to the top of the weighing sensor 25 and located below the discharging opening 111 of the conveying pipe 11. Both sides of the top of the receiving table 26 corresponding to the tipping direction are provided with side plates 27. Four corners of the bottom of the receiving table 26 are provided with auxiliary stabilizing sliding rods 261 passing through the tipping table 22, and the auxiliary stabilizing sliding rods 261 are all slidably connected to the tipping table 22. The tipping motor 23 drives the tipping table 22 to rotate, tipping the receiving table 26 from the horizontal position to the inclined position, so that the tea leaves are tipped from the receiving table 26 into the packaging bag. The weighing sensor 25 monitors the weight of the tea leaves on the receiving table 26 in real time. When the preset value is reached, the feeding is stopped and the tipping is prepared. The angle sensor 24 is used to detect the rotation angle of the tipping table 22 to ensure the accuracy of the tipping process.

[0036] Furthermore, a control cabinet 5 is arranged on one side of the conveying mechanism 3. The output ends of the angle sensor 24 and the weighing sensor 25 are both connected to the input end of the control cabinet 5. The input ends of the feeding motor 13, the tipping motor 23, the first conveying motor 32, the second conveying motor 44, the electric telescopic rod 47 and the vacuum pump 49 are all connected to the output end of the control cabinet 5. The control cabinet 5 serves as the control system of the entire device, receives the signals from the angle sensor 24 and the weighing sensor 25, and controls the operation of the feeding motor 13, the tipping motor 23, the first conveying motor 32, the second conveying motor 44, the electric telescopic rod 47 and the vacuum pump 49 according to the preset program.

[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered within the protection scope of the present application.
