Continuous rolling machine for tea

Abstract

The invention relates to a continuous rolling machine for tea. The machine comprises a rack, a parallelogram mechanism, a rolling device, a central motor and a pressing mechanism, wherein the rolling device comprises a plurality of pairs of rolling covers and rolling plates, which are arranged in parallel up and down; the opposite position of each pair of rolling cover and rolling plate is that the rolling cover is positioned above the rolling plate; a plurality of layers of rolling plates are fixed on the rack; a plurality of layers of rolling covers are mounted on a transmission shaft and connected with the central motor through the pressing mechanism; the plurality of rolling plates are fixed; the plurality of rolling covers are driven by the central motor and the pressing mechanism to do compound motion of rotating and reciprocating up and down; meanwhile, the central motor, the pressing mechanism and the plurality of rolling covers are driven by the parallelogram mechanism to circumferentially move in the plane at a constant speed; the plurality of pairs of rolling covers and rolling plates form a plurality of rolling areas; tea is rolled to be compact and perfectly round. The machine is simple in structure and simple and convenient to operate, can be used for rolling tea continuously, and can implement continuous rolling process of a tea processing line.

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-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

(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 and price are also very high; (2) The whole set of operation and control system It is very complicated and requires high cultural quality of operation and maintenance personnel
