Description

Technical Field

[0001] This utility model relates to the field of green tea sieving machines, and in particular to a multi-layer automatic green tea sieving device. Background Technology

[0002] Oolong tea, also known as blue tea, is a type of tea that falls between green and black tea. During its production, oolong tea utilizes a multi-layered automatic sieving system to efficiently separate tea leaves into different grades and sizes. Based on characteristics such as size, shape, and weight, the tea leaves are divided into different grades to ensure the uniformity and quality of the final product.

[0003] The existing multi-layer automatic sieving devices used for oolong tea make it easy for tea dust and fragments to enter the screen mesh during the sieving process, causing blockages. The screens need to be cleaned regularly. Since the multi-layer sieving device has multiple sets of screens stacked in parallel, the small gaps between the screens make cleaning difficult. This requires more downtime for manual cleaning during production, causing production line stagnation and significantly reducing the sieving efficiency of oolong tea. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-layer automatic sieving device for green tea, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-layer automatic sieving device for oolong tea includes a sieving machine. The sieving machine is equipped with a first screen and a second screen. A cleaning plate is positioned between the first and second screens. Several cleaning brushes are arranged on both sides of the cleaning plate, and these brushes are evenly spaced and arrayed. The cleaning brushes are respectively attached to the first and second screens. A connecting member is provided on the cleaning plate. Two sets of moving grooves are formed on the inner wall of the sieving machine. Moving plates are arranged within the two sets of moving grooves. One end of each moving plate is connected to the connecting member. An adjusting groove is formed on one side of each moving groove, and an adjusting plate is arranged within the adjusting groove. One end of the adjusting plate is fixedly connected to one side of the moving plate. A moving component is provided on the sieving machine to drive the adjusting plate to move.

[0007] As a further embodiment of this utility model, the moving component includes a screw rod disposed in an adjusting groove, the screw rod being threadedly connected to an adjusting plate, one end of the screw rod penetrating the adjusting groove, a motor being clamped to one side of the screening machine, one set of the two sets of screw rods being connected to the output end of the motor, and a transmission component being disposed on the screw rod.

[0008] As a further embodiment of this utility model, a protective shell is snapped onto one side of the screening machine, and one end of each of the two sets of screws extends into the interior of the protective shell.

[0009] As a further embodiment of this utility model, the transmission component includes a sprocket fixedly connected to the screw, and two sets of sprockets are meshed with chains.

[0010] As a further embodiment of this utility model, the connector includes a slot formed on the cleaning plate, a locking block is engaged in the slot, and one end of the locking block is fixedly connected to one side of the moving plate.

[0011] As a further embodiment of this utility model, a positioning hole is provided on one side of the cleaning plate, and a circular through hole is provided on one side of the card block, with a spring installed inside the circular through hole.

[0012] As a further embodiment of this utility model, one end of the spring is fixedly connected to a positioning block, and one end of the positioning block extends into the positioning hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] The movable component drives the adjusting plate to slide inside the adjusting groove. The adjusting plate simultaneously drives the movable plate to slide inside the movable groove. The movable plate, in conjunction with the connecting piece, synchronously drives the cleaning plate to move. The cleaning plate drives the cleaning brushes on both sides to clean the first and second screens at the same time, clearing the blockages on the screens. This solves the problem of the small screen spacing, which makes cleaning difficult. It greatly reduces the downtime for cleaning during production, speeds up the cleaning efficiency of the screens, and thus greatly improves the sorting efficiency of green tea.

[0015] The positioning block is engaged with the slot by a spring, which presses one end of the positioning block into the positioning hole, further connecting the positioning block and the slot securely together. This connects the cleaning plate and the moving plate, making it easier for the moving plate to move the cleaning plate and allowing staff to maintain the cleaning brush, thus improving the convenience of equipment maintenance.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, a multi-layer automatic sieving device for green tea includes a sieving machine 1, on which a first screen 2 and a second screen 3 are provided. A cleaning plate 4 is provided between the first screen 2 and the second screen 3. Several cleaning brushes 5 are provided on both sides of the cleaning plate 4. The cleaning brushes 5 are evenly distributed in an array and are respectively attached to the first screen 2 and the second screen 3. Connecting parts are provided on the cleaning plate 4. Two sets of moving grooves 7 are opened on the inner wall of the sieving machine 1, and moving plates 6 are provided in the two sets of moving grooves 7.

[0025] In this embodiment, one end of the movable plate 6 is connected to the connector, and an adjustment groove 8 is provided on one side of the movable groove 7. An adjustment plate 9 is provided in the adjustment groove 8, and one end of the adjustment plate 9 is fixedly connected to one side of the movable plate 6. A movable component is provided on the screening machine 1, which is used to drive the adjustment plate 9 to move.

[0026] To facilitate the cleaning of clogged screens, the moving component first drives the adjusting plate 9 to slide inside the adjusting groove 8. Simultaneously, the adjusting plate 9 drives the moving plate 6 to slide inside the moving groove 7. The moving plate 6, in conjunction with the connecting piece, synchronously drives the cleaning plate 4 to move. The cleaning plate 4 drives the cleaning brushes 5 on both sides to clean the first screen 2 and the second screen 3, clearing the blockages on the screens. This solves the problem of the small screen spacing, which makes cleaning difficult, greatly reducing the downtime for cleaning during production, speeding up the cleaning efficiency of the screens, and thus greatly improving the sorting efficiency of green tea.

[0027] In this embodiment, the moving component includes a screw 10 disposed in the adjusting groove 8. The screw 10 is threadedly connected to the adjusting plate 9. One end of the screw 10 passes through the adjusting groove 8. A motor 13 is clamped to one side of the screening machine 1. One set of two screws 10 is connected to the output end of the motor 13. A transmission component is disposed on the screw 10.

[0028] First, the motor 13 drives one set of screws 10 to rotate, which in turn drives another set of screws 10 to rotate, so that the two sets of screws 10 can rotate synchronously. The two sets of screws 10, in conjunction with the thread, can drive the adjusting plate 9 to move, making it easier for the cleaning brush 5 to clean the screen.

[0029] A protective shell 19 is attached to one side of the screening machine 1, and one end of each of the two sets of screws 10 passes through the interior of the protective shell 19. The protective shell 19 provides a certain degree of protection for the transmission components and increases the service life of the equipment.

[0030] In this embodiment, the transmission component includes sprockets 11 fixedly connected to the screw 10, and chains 12 are meshed on two sets of sprockets 11.
