Tea leaf flattening, shaping and dewatering assembly line

Abstract

The invention provides a tea leaf flattening, shaping and dewatering assembly line. The work plane of an upper mesh belt and the work plane of a lower mesh belt are divided into a flattening zone and a drying and dewatering shaping zone, a support plate is arranged below the upper mesh belt of the flattening zone, a reciprocating trolley capable of longitudinally walking to and fro is arranged on the upper mesh belt, a pinch roller assembly capable of grinding the tea leaves flat is mounted on the reciprocating trolley, the pinch roller assembly comprises two pinch roller shafts and pinch rollers capable of rotating on the pinch roller shafts, the two pinch roller shafts are fixed on a cross shaft through a left lifting rod and a right lifting rod, the cross shaft is in rotatable connection with the reciprocating trolley, and balancing weights are arranged on the left lifting rod and the right lifting rod. According to the invention, the conveying of the upper mesh belt and the lower mesh belt and the combination of the reciprocating trolley and the pinch roller assembly are adopted, the tea leaves on the work plane of the upper mesh belt and the work plane of the lower mesh belt are ground to and fro by the pinch rollers, the grinding path is long, the tea leaf flattening effect is great, flattening, clamping and drying are continuously carried out, continuous operation can be realized in the flattening, drying, dewatering and shaping process of the tea leaves, the automation level is high, the shapes of the dried tea leaves are consistent, and the tea leaf quality is improved.

Description

technical field [0001] The invention relates to tea processing equipment, in particular to tea shape shaping equipment, in particular to tea flattening, shaping and dehydration equipment. Background technique [0002] Among the traditional famous and high-quality tea leaves in our country, many tea leaves are flat in appearance. For example: Longjing tea, Taiping Houkui tea, Lu'an Guapian tea, etc. Now there are more new famous and high-quality tea leaves that are flat in shape. [0003] For example, Taiping Houkui, the production method of Taiping Houkui is also very particular. The old craft of Taiping Houkui is divided into picking, picking, spreading, finishing, hair drying, foot drying, and re-baking, a total of seven processes are made. With the passage of time, the processing technology of Taiping Houkui is also changing now. The processing technology is greening, tea pulling, flattening and drying. A bucket pot with a diameter of 70 cm is used for finishing, heate...

AI Technical Summary

Problems solved by technology

In addition, there are several pressing rollers on the working table of the conveying mesh belt, and the tea workpieces to be processed move forward through the rolling between the conveying mesh belt and the pressing rollers. Flattening requirements, the quality is not high

Mesh clip type shaping dryer, the frame is equipped with circulating upper mesh belt and lower mesh belt, the working surface of the upper mesh belt and the lower mesh belt are close to each other, and infrared rays are installed on the working surface of the upper mesh belt and the lower mesh belt. The heating device only has the function of drying, dehydrating and shaping, and cannot realize the function of flattening the tea leaves

In addition, when the flattened tea leaves from the tea flattening machine enter the mesh clamp type drying machine, the position of the tea leaves changes, resulting in the gap between the upper mesh belt and the lower mesh belt that cannot enter the mesh clip according to the original shape and flattened state. On the working surface, there is a high rate of broken tea, which affects the quality of tea

[0005] Patent No. ZL 200720044519.5 is a Chinese utility model patented flat tea press type continuous molding dryer. The upper and lower driving drums and the upper and lower driven drums are respectively connected by upper and lower conveying mesh belts running through the oven. There are several pairs of upper and lower rolling rollers installed vertically in the middle of the upper and lower conveying mesh belts respectively. Realize the flattening of tea leaves

The patent No. ZL200910155834.9 is a Chinese invention patent flat tea continuous flattening machine, which uses a conveyor belt and a kneading belt to realize tea flattening, but the tea flattening effect is also not ideal

The above-mentioned structure especially cannot realize the flattening and shaping dehydration of Taiping Houkui
