Continuous tea-twisting machine

Abstract

The invention relates to a continuous tea-twisting machine which comprises a frame, a twisting device and a drive mechanism. The twisting device comprises a feed port, a twisting drum, a twisting lid and a discharge port, wherein, the feed port is positioned above the twisting drum; the discharge port is positioned below the twisting drum; the twisting drum is arranged in the twisting lid; the twisting drum consists of an upper section of the frustum of a cone and a lower section of the inverted frustum of a cone which are connected with each other; spiral guide vane ribs are arranged on the twisting drum; the twisting lid consists of an upper twisting lid and a lower twisting lid; an initial twisting area is formed between the upper twisting lid and the upper section of the twisting drum; the volume of the initial twisting area is increasingly reduced from the top to the bottom; a twisting extrusion area is formed between the lower twisting lid and the lower section of the twisting drum; the volume of the twisting extrusion area is smaller than the volume of the initial twisting area; the twisting lid is fixedly connected with the frame; longitudinal rotating shafts are arranged on the upper end part and the lower end part of the twisting drum; and a rotating shaft fixing seat is arranged on the frame; and the rotating shafts are in transmission connection with drive mechanism. The tea continuous twisting machine has the advantages of simple structure, realization of continuous twisting, uniform twisting quality of tea, low cost, and energy and resource conservation.

Description

(1) Technical field [0001] The invention relates to a tea continuous rolling machine. (2) Background technology [0002] Kneading is an extremely important process in the primary processing of tea, and its quality determines the quality of finished tea. At present, the rolling principle of tea leaves is basically the same, which is to let the green (or withered) leaf clusters use the crank linkage mechanism to drive the kneading barrel to make a uniform speed parallel circle on the kneading plate in the kneading space composed of the kneading barrel, the gland and the kneading plate. The movement is subject to the combined action of the multi-directional forces of the kneading barrel, gland, kneading plate, ribs and leaf clusters themselves, making them knead along the main veins of their respective leaves into tight and round cords, and at the same time break the leaf cells, thereby Complete the kneading process. The structure of the kneading machine is also similar, cons...

AI Technical Summary

Problems solved by technology

[0005] (1) Unstable kneading quality: At present, kneading machines with barrel-disc structure are mainly single-machine kneading. There is no metering device for leaf throwing, no timing device for kneading, and the timing and time of pressurization are controlled by electromechanical devices. They are completely manual. Judgment is very arbitrary

Although the green leaves are from the same batch, the rolling quality is different, resulting in uneven quality of finished tea

[0006] (2) The efficiency is not high: the kneading machine with barrel-disc structure, its feeding, pressure adjustment and unloading are all manually operated, and the efficiency is low

At the same time, the kneading machine with the barrel-disc structure works intermittently, and can only knead one barrel at a time. It is difficult to realize the continuous rolling process, and the work efficiency is low. After kneading, it is necessary to add a process-deblocking process

[0007] (3) Cannot adapt to assembly line and automatic production

[0009] (1) The high-tech content of the whole set of equipment is very high, so the cost is also increased accordingly;

[0010] (2) The entire kneading system is very complicated, the body is huge, and the cultural quality of the operators is very high.
