Description

Technical Field

[0001] The invention discloses a white tea weighing device and a weighing tea steaming machine, which belong to the technical field of tea making equipment according to the International Patent Classification (IPC). Background Art

[0002] White tea is a slightly fermented tea and a traditional famous tea created by Han tea farmers. White tea is slightly cold in nature and contains a variety of amino acids. It has the effects of reducing fever, removing heat and detoxifying. White tea also contains a lot of vitamin A. The health-preserving effects of white tea are also increasingly valued by people.

[0003] In the production process of white tea, steaming tea is one of the steps. The tea leaves must be weighed first and then sent to the steaming equipment. Since the tea leaves become different in thickness, size and length during the production process, the fine materials are often transported first and the coarse materials are output later, resulting in obvious differentiation in thickness and size of the steamed tea and subsequent packaged tea leaves, and the quality of the tea leaves cannot be guaranteed.

[0004] The transportation fluidity of white tea is poor during the production process, and the existing weighing channel is easily blocked, which reduces production efficiency and even affects the operation of the mechanism equipment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a white tea weighing device, which provides a double-channel outlet through a vibrating plate so that coarse and fine materials can be vibrated and output for weighing at the same time, thereby ensuring the quality of the tea.

[0006] To achieve the above object, the present invention is achieved through the following technical solutions:

[0007] A white tea weighing device comprises a frame, a hopper is arranged on the frame, a vibration plate is arranged at the lower end of the hopper, the vibration plate has a vibration cavity, a side wall opening of the vibration cavity is connected to a first channel, a second channel is arranged at one side of the first channel, the second channel receives fine tea leaves in the first channel, the first channel transports coarse tea leaves outwardly, the two channels vibrate synchronously with the vibration plate to transport coarse and fine tea leaves outwardly, a weighing hopper is arranged below the outlets of the two channels, and a discharge channel is arranged at the bottom of the weighing hopper to transport the tea leaves outwardly to enter the next process.

[0008] Furthermore, the bearing surface of the second channel is lower than the bearing surface of the first channel for receiving the fine material output by the vibration plate, and the first channel and the second channel form a stepped double channel structure.

[0009] Furthermore, a screw is arranged in the hopper to stir the tea leaves into the vibration cavity of the vibration plate.

[0010] Furthermore, one or more guide plates are provided on the peripheral wall of the hopper adjacent to the lower port, and the guide plates are used to loosen the agitated materials.

[0011] Further, the guiding pieces are arranged circumferentially along the hopper, and each guiding piece is inclined and installed on the side wall of the hopper, with an inclination angle of 30 - 50 degrees.

[0012] The present invention also provides a weighing and steaming tea machine, which includes the above-mentioned white tea weighing device and a rotating tea steaming device. The rotating tea steaming device includes a turntable that can rotate around a central axis. There are more than two material cylinders arranged on the turntable. When the turntable rotates, each material cylinder is sequentially docked with the discharge port of the white tea weighing device, and a tea steaming station is arranged on the rotation path of the material cylinder of the turntable to perform tea steaming operations.

[0013] Further, a driving mechanism is arranged below the turntable to make the turntable rotate circumferentially. The driving mechanism is a motor and is connected to the turntable through a worm gear reduction mechanism.

[0014] In the white tea weighing device of the present invention, a first channel and a second channel are arranged on one side of the vibrating disk. The thick and thin tea leaves are vibrated into the first channel. Since the first channel is connected to the side of the second channel, the thin tea leaves enter the second channel and are conveyed towards the outlet. At this time, the thick tea leaves are conveyed from the first channel towards the outlet. Since the second channel is far from the vibrating disk, when it is conveyed to the outlet, the thick and thin tea leaves fall into the weighing hopper simultaneously, avoiding the separation of thick and thin tea leaves and improving the quality of the tea.

[0015] The invention also provides a weighing and steaming tea machine, which adopts a turntable structure and can simultaneously set multiple material cylinders for receiving materials and performing tea steaming operations, with high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A second channel 32 is provided on one side of the first channel 31. The second channel 32 receives the fine tea materials in the first channel 31. The first channel 31 conveys the coarse tea materials outward. The two channels vibrate synchronously with the vibrating disk to convey the coarse and fine tea materials outward. Below the outlets of the two channels, there is a weighing hopper 4. The bottom of the weighing hopper 4 is provided with a discharge channel to convey the tea outward into the next process, and the discharge port 41 of the discharge channel. In the present invention, the bearing surface of the second channel 32 is lower than that of the first channel 31 for receiving the fine materials output by the vibrating disk. The first channel 31 and the second channel 32 form a stepped double-channel structure. A screw 21 is provided in the hopper 2 to stir the tea into the vibrating cavity of the vibrating disk 3. The screw is controlled by a screw motor. One or more guiding pieces 22 are provided on the peripheral wall of the hopper 2 near the lower port. The guiding pieces are used to loosen the agitated materials. The materials make a centrifugal motion under the action of the guiding pieces and the screw. The guiding pieces can be 2 pieces, 3 pieces, 4 pieces or more pieces, and are arranged circumferentially along the hopper.
