Technical Field

[0001] The utility model relates to the technical field of tea production, in particular to a layered screening device for the production of Eucommia ulmoides leaf tea. Background Art

[0002] Eucommia ulmoides leaf tea is made from Eucommia ulmoides leaves. Eucommia ulmoides is a common Chinese herbal medicine plant, and its leaves are rich in beneficial bioactive ingredients and are used to make tea beverages. Because the tea contains rich natural nutrients, it is considered to have some health care effects. The layered screening device for the production of Eucommia ulmoides leaf tea generally refers to the equipment used for grading and screening in the production process of Eucommia ulmoides leaf tea. The main function of such equipment is to classify the tea into different grades according to the size, shape and other characteristics of the tea to ensure the quality and consistency of the product.

[0003] After retrieval, the existing Chinese patent publication number is: CN220215615U, a screening device for layered collection of tea for tea processing, which relates to the technical field of tea processing, including a device base. A U-shaped frame is arranged on the upper side of the device base. Two sliding columns II are fixed on both the left and right sides of the U-shaped frame. A double-shaft motor is arranged at the center inside the U-shaped frame, and a motor base is fixedly installed outside the double-shaft motor. The tea screening structure composed of a number of staggered screening thin rods set by the utility model solves the problems of tea clogging the filter screen and being difficult to clean. And by setting the density of the upper and lower layer screening thin rods, multi-level layered screening is realized, and through the vibration structure composed of a motor base, a U-shaped frame and a number of sliding columns and springs in the device base, multi-level automatic screening and collection of tea are realized, greatly improving the production efficiency of tea. And because the device is easy to clean, the screening structure can maintain a high-quality screening state for a long time, and the screening effect is better than that of the traditional screening device.

[0004] In the specific implementation manner of the above patent, the internal double-shaft motor drives the eccentric blocks connected at both ends to rotate, cooperating with the first springs on a number of sliding columns I on both sides of the motor base and the second springs on a number of sliding columns II on both sides of the U-shaped frame, so that a number of screening frame structures connected to the upper side of the motor base shake up and down, left and right. The density of the screening thin rods in the uppermost screening frame is the smallest, and the density of the screening thin rods in the lowermost layer is the largest. From top to bottom, the screening filter diameter of the screening thin rods becomes smaller and smaller, thereby realizing multi-level layered automatic screening of the tea put into the screening frame. The above patent realizes multi-level classification of tea by using vibration and screening frames with multiple different screening filter diameters, realizes multi-level automatic screening and collection of tea, greatly improves the production efficiency of tea, and because the device is easy to clean, the screening structure can maintain a high-quality screening state for a long time, and the screening effect is better than that of the traditional screening device.

[0028] Working principle: when it is necessary to screen the Eucommia tea leaves, the conveyor belt 16 will feed the Eucommia tea leaves into the interior of the screening seat 3 at the top. At this time, the motor 4 is started, and the driving rod 5 is driven by the motor 4, which then drives the rotating plate 6 to rotate inside the screening seat 3. The design of the telescopic plate 12 is to be close to the inner bottom end of the screening seat 3 under the push of the pushing spring 10, and the Eucommia tea leaves inside the screening seat 3 are moved by the rotation of the rotating plate 6 and the telescopic plate 12. During the moving, smaller tea leaves will fall into the screening seat 3 at the lower end, thereby realizing the layered screening of the tea leaves in the screening seat 3. The screened tea leaves will fall into the interior of the guide plate 13 under the rotation of the rotating plate 6 and the telescopic plate 12, and will be introduced into the interior of the collecting box 23 through the guide plate 13. By using the rotating rotating plate 6 and the telescopic plate 12 to cooperate, the Eucommia tea leaves are moved. The leaves are screened in layers to avoid the breakage of the tea leaves caused by excessive vibration during screening, which results in the loss of the tea leaves, thereby ensuring the appearance and taste of the tea leaves and improving the overall quality. When the conveyor seat 15 is used to feed the tea leaves, the tea leaves will pass between the two baffles 17 when leaving the conveyor seat 15, and the push spring 18 will push the adjusting rod 19 to expand, while the tightening ring 20 and the adjusting rod 19 cooperate. By adjusting the tightening ring 20 outside the adjusting rod 19, the expansion angle of the baffle 17 can also be adjusted. The tea leaves are centered by using a centering device to ensure that the tea leaves can be accurately delivered to the interior of the collecting box 23, thereby avoiding production interruptions or delays caused by inaccurate tea position, improving the operation efficiency of the production line, reducing manual intervention, and improving the stability of the production process.
