Description

Technical Field

[0001] This utility model relates to the field of tea screening, and in particular to a tea stratification screening device. Background Technology

[0002] During the processing of tea, it is often necessary to use stratification and screening equipment to sort tea leaves of different sizes.

[0003] Most existing screening equipment does not have an automatic cleaning mechanism. During the tea screening process, tea leaves are easily stuck in the mesh of the screen, requiring staff to manually remove them after the screening is completed, which increases the workload and makes the equipment inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the following problems existing in the prior art: In the process of tea screening, existing screening equipment is prone to tea leaves getting stuck in the mesh of the screen, which requires workers to manually handle the problem after the screening is completed, which is quite troublesome.

[0005] To address the problems existing in the prior art, this utility model provides a tea stratification and screening device, including a screening machine and a screen. An electric guide rail is provided above the screening machine, and a movable seat is movably mounted on the electric guide rail via a slider. A mesh cleaning component is provided on the movable seat.

[0006] Furthermore, the mesh cleaning assembly includes an electric push rod and multiple insert rods. The electric push rod is fixed above the movable base, and a lifting seat is provided at the output end below the electric push rod. The multiple insert rods are fixed below the lifting seat.

[0007] Furthermore, the number of the insert rods is the same as the number of mesh openings in a row of the screen, and the diameter of the insert rods is smaller than the diameter of the mesh openings of the screen.

[0008] Furthermore, each of the inserts is equipped with an elastic block at its bottom end, which prevents the insert from damaging the tea leaves during use.

[0009] Furthermore, the mesh cleaning assembly also includes a vision camera on one side of the movable seat, which is electrically connected to the control components of the electric guide rail and the electric push rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] After the screening process is completed, the electric guide rail starts and drives the sliding seat to move above the screen via the slider. During the movement, the screen mesh is detected by a vision camera. If tea leaves are found stuck in the mesh, the movement stops. Then, the electric push rod starts and drives the lifting seat and the insertion rod to descend. The descending insertion rod is inserted into the mesh of that row to knock the tea leaves stuck in the mesh off, thus achieving the purpose of automatic screen cleaning and solving the problem of the existing manual cleaning by staff, which is troublesome and inconvenient.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figure 1-3 As shown, a tea stratification and screening device includes a screening machine 1 and a screen 5. An electric guide rail 6 is provided above the screening machine 1. A movable seat 3 is movably mounted on the electric guide rail 6 via a slider 9. A mesh cleaning component is provided on the movable seat 3.

[0020] In this embodiment, the mesh cleaning assembly includes an electric push rod 4 and multiple insert rods 2. The electric push rod 4 is fixed above the movable base 3. A lifting seat 8 is provided at the output end below the electric push rod 4. The multiple insert rods 2 are fixed below the lifting seat 8. The number of insert rods 2 is the same as the number of mesh holes in a row of the screen 5. The diameter of the insert rods 2 is smaller than the diameter of the mesh holes of the screen 5. Each insert rod 2 has an elastic block at its bottom end. During use, the elastic block can prevent the insert rods 2 from puncturing the tea leaves. The mesh cleaning assembly also includes a vision camera 7 on one side of the movable base 3. The vision camera 7 is electrically connected to the electric guide rail 6 and the control components of the electric push rod 4.

[0021] Working principle description: The worker pours the tea leaves to be screened onto the screen 5. The vibrating component of the screening machine 1 then drives the screen 5 to vibrate. As the screen 5 vibrates, the tea leaves are displaced. During this process, smaller tea leaves pass through the screen 5 and fall to the bottom, thus completing the screening. After the screening is completed, the electric guide rail 6 starts and drives the sliding block 9 to move the moving seat 3 above the screen 5. During the movement, the vision camera 7 detects the mesh of the screen 5. If tea leaves are detected stuck in the mesh, the movement stops. Then, the electric push rod 4 starts and drives the lifting seat 8 and the insertion rod 2 to descend. The descending insertion rod 2 inserts into the mesh of that row to knock the tea leaves stuck in the mesh. After processing, the insertion rod 2 rises, and the moving seat 3 continues to move in conjunction with the vision camera 7 for detection until the screen 5 is cleaned. This achieves the purpose of automatic cleaning of the screen 5, solving the problem of the inconvenience and trouble of manual cleaning by workers, and increasing the practicality of this device.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
