Continuous tea twisting machine

Abstract

The invention relates to a continuous tea twisting machine. The continuous tea twisting machine comprises a rack, a twisting device, a central motor, a parallelogram mechanism and a pressing mechanism, wherein the twisting device comprises a twisting plate and a twisting cover which is positioned above the twisting plate; a long and narrow rotary space comprising a spiral guide-leaf plate, a leaf pressure plate and the twisting plate forms a twisting region; the twisting plate is immobile; under the driving of the central motor and the parallelogram mechanism, the twisting cover performs compound motion of rotation and constant-speed planar circular motion; the central motor drives the pressing mechanism to rotate; a presser forces a pressure bearing plate to drive the leaf pressure plate to move downwards under the driving of a double-ended stud; by virtue of a spring, the pressure bearing plate and the leaf pressure plate are upwards returned; tea leaves are arranged in the twisting device, rubbed by the spiral leaf-guide plate, bulged patterns and the twisting plate wall, and intermittently pressed and extruded through the leaf pressure plate for being twisted into tight and round shapes. The continuous tea twisting machine is tea making machinery which is simple in structure and convenient operate, and can meet the requirements of a tea processing assembly line, and requirements on cultural quality of an operator are not high.

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

[0004] From the above working principle and structure, it can be concluded that the traditional kneading machine has the following problems: (1) The kneading quality is unstable: at present, the kneading machine with the barrel-pan structure is mainly single-machine kneading, and there is no metering device for leaf throwing and no timing device for kneading. The timing and time of pressurization have no electromechanical control, and are completely dependent on manual operation and judgment, which is very random

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

(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-disk 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

(3) Cannot adapt to assembly line and automatic production

[0005] From the above description, it can be concluded that the automatic kneading machine has the following problems: (1) The high-tech content of the whole set of equipment control system is very high, and the equipment body is huge, so the cost is correspondingly increased; (2) The whole set of operation and control system is very complicated , has high requirements on the cultural quality of the operators
