Double-acting multi-layer continuous tea kneading machine

Abstract

The invention relates to a double-acting multi-layer continuous tea kneading machine which comprises a frame, a kneading device, a central motor, a pressing mechanism and a parallelogram mechanism; the kneading device comprises multiple sets of kneading boards and kneading covers, the multiple sets of kneading boards and kneading covers are arranged in an upper-lower parallel arrangement; in each set of kneading board and kneading cover, the relative position of the kneading board and the kneading cover is that the kneading cover is positioned above the kneading board; the multiple layers of kneading board are installed on a swing frame of the parallelogram mechanism; the multiple layers of kneading covers are installed on a transmission shaft of the pressing mechanism, the multiple layers of kneading covers are connected with the central motor by the pressing mechanism; the multiple layers of kneading board are driven by the parallelogram mechanism to perform uniform-speed plane circling motion, and the multiple layers of kneading covers are driven by the central motor and the pressing mechanism to perform rotation and up-down reciprocating compound motion. The double-acting multi-layer continuous tea kneading machine has simple structure and simple operation, can fully knead, and solves the problem of continuous kneading process of a tea processing line. By adjustment of the rotation speed of the parallelogram mechanism and the central motor, granular bead tea can also be kneaded out.

Description

(1) Technical field [0001] The invention relates to a double-action multi-layer 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 mac...

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 narration, it can be concluded that the automatic kneading machine has the following problems: (1) the whole set of equipment has a huge body and complex structure, so that the cost and price are correspondingly high; The cultural quality of personnel is very high
