Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tea processing, especially to a pressure adjusting device of a tea rolling machine. BACKGROUND

[0002] The tea rolling machine is a kind of equipment specially used in the tea making process, and its main function is to make tea strips tight and leaf tissues moderately damaged through external force, so as to squeeze tea juice and achieve the purpose of forming and facilitating tea brewing. The pressure adjusting device of the tea rolling machine is an important component for ensuring that tea receives appropriate pressure during rolling. Different types of tea have different leaf tenderness and wilting degrees, so the pressure applied during rolling should also be different. Adjusting the pressure of the tea rolling machine helps to maintain the quality of tea.

[0003] Chinese patent publication No. CN206403109U discloses an adjustable pressure cover for a tea rolling machine, which includes a pressure adjusting device fixed by a fixed frame. The pressure adjusting device includes a first adjusting rod and a second adjusting rod. One end of the first adjusting rod is arranged on the fixed frame and connected with the output end of a motor, and the other end is provided with external threads. One end of the second adjusting rod is fixedly connected with the pressure cover, and the other end is provided with a fixed hole in the axial direction. The fixed hole is provided with internal threads. The first adjusting rod and the second adjusting rod are connected through the external threads and the internal threads. The device further includes an L-shaped first fixed plate. One panel of the L-shaped first fixed plate is provided with a special-shaped hole for limiting the circumferential rotation of the second adjusting rod. The second adjusting rod is a structure matched with the special-shaped hole and can axially move through the special-shaped hole. The free end of the other panel is arranged on the fixed frame. The above-mentioned device can mechanically adjust the different amplitudes of the up and down positions of the pressure cover, and is beneficial to reducing the labor cost.

[0004] Although the device in the above-mentioned document can adjust the pressure cover of the tea rolling machine, it cannot adjust the diameter of the pressure cover. The pressure required during the rolling process of different types of tea may be different, and the diameter of the pressure cover may also be different. If the diameter of the pressure cover is fixed, it may not be suitable for all types of tea, resulting in poor rolling effect. UTILITY MODEL CONTENTS
