Electromagnetic follow-up pressure carding machine

Abstract

The invention discloses an electromagnetic follow-up pressure carding machine which comprises a frame, a heating unit, a U-shaped groove pot, a crank and a connecting rod, wherein the heating unit and the U-shaped groove pot are arranged on the frame; the U-shaped groove pot comprises a plurality of U-shaped grooves and is supported by rollers; the crank is connected with a driving chain wheel mounted on the output shaft of a frequency conversion motor through a chain; the connecting rod is hinged with the crank shaft and a slide block arranged on one side of the U-shaped groove pot; an electromagnetic support (9) fixed in four corners of the U-shaped groove pot is arranged above the inlet end and the outlet end of the U-shaped groove pot (7); electromagnetic coils (11) and armatures (10)controlled by the electromagnetic coils are arranged at the positions corresponding to two ends of the U-shaped grooves of the U-shaped groove pot and are mounted on the electromagnetic support abovethe inlet end and the outlet end of the U-shaped groove pot; a pressurizing bar (8) with two ends coated with steel plates is arranged in each U-shaped groove of the U-shaped groove pot. Under the action of electromagnetic forces, the pressurizing bars with two ends coated with the steel plates in the U-shaped groove pot are automatically released and recovered, so that the purposes of controlling the pressurizing time of tea leaves in the U-shaped groove pot and of realizing automatic control over the pressure during tea leaf shaping are achieved.

Description

technical field [0001] The invention relates to a tea slitting machine, in particular to an electromagnetic automatic pressurized tea slitting machine, which belongs to the technical field of tea processing equipment. Background technique [0002] The tea stripping machine is one of the key equipment for green tea finishing and shaping. It has been widely used in the tea processing production line. The tea leaves are thrown, collided, rubbed, squeezed and other forces in the reciprocating U-shaped tank to make the shape. At the same time, corresponding physical and biochemical changes of tea leaves occur under the heat of the heating device: to inactivate the activity of polyphenol oxidase, evaporate part of the water, volatilize the smell of green grass, and soften the tissue; to achieve the purpose of finishing and shaping. In order to meet the requirements of different strip shapes (needle shape, flat shape, etc.), in the practice of tea making for many years, it is usual...
