Return pull-type decorticating machine

Abstract

A reverse-drawing decorticating machine comprises a frame, a hemp feeding channel and a decorticating roller which are installed on the frame, a power arrangement which is used for driving the decorticating roller and a beating plate which is installed on the circumferential surface of the decorticating roller, the reverse-drawing decorticating machine is characterized in that the beating plate comprises a working part and an interconnecting piece which is connected with the decorticating roller, the angle a between the working part and the interconnecting piece is 40DEG C-50DEG C, and the orientation of the angle a between the working part and the interconnecting piece is opposite to the rotation direction A of the decorticating roller, the beating plate of the decorticating machine of the invention has big reaction area with the hemp, which can fully hummer and pressure a hemp rod, efficiently reduce the damage of hemp fiber and improve the efficiency of hemp decorticating and quality of the hemp decorticating.

Description

technical field [0001] The invention relates to a back-pull type hemp stripping machine, in particular to a manual back-pull type hemp stripping machine. Background technique [0002] At present, the back-pull type hemp stripping machine is widely used because of its simple structure, high work efficiency and good quality of hemp stripping. Structurally speaking, the back-pull type stripping machine mainly contains two major classes, and a kind of is the roller pressing plate type, comprises stripping the hemp roller, beats plate, press plate, power unit, frame, feeding hopper etc., as Chinese patent document CN2876107Y And CN87201275U, the problem that its main existence is to only rely on the extruding and striking effect between the beating plate on the single roller when rotating and the pressure plate to peel off the hemp, and the efficiency is low, and the quality of peeling hemp is poor; the other is double roller Drum type, including two stripping hemp rollers, powe...

Problems solved by technology

Structurally speaking, the back-pull type stripping machine mainly contains two major classes, and a kind of is the roller pressing plate type, comprises stripping the hemp roller, beats plate, press plate, power unit, frame, feeding hopper etc., as Chinese patent document CN2876107Y And CN87201275U, the problem that its main existence is to only rely on the extruding and striking effect between the beating plate on the single roller when rotating and the pressure plate to peel off the hemp, and the efficiency is low, and the quality of peeling hemp is poor; the other is double roller Drum type, including two stripping hemp rollers, power unit, frame, feeding hopper etc. that are provided with beating plate, as Chinese patent document CN2672086Y and CN2491462Y, owing to be provided with two hemp stripping rollers, make production efficiency and stripping The quality of hemp has been improved to a certain extent, but there are still some problems as follows: the beating plate on the hemp-peeling roller is usually a lamellar steel sheet perpendicular to the tangential direction of the surface of the hemp-peeling roller. Reasonable, the top of the beating board is in vertical contact with the hemp rod during work, and the striking surface is small, which affects the efficiency and quality of the hemp stripping. Moreover, the top of the beating board vertically hits the hemp rod, which will cause greater damage to the hemp fiber. It is not easy to set the beating plate on the surface of the hemp peeling roller, the connection strength between the beating plate and the hemp peeling roller is low, it is easy to be damaged, and the setting angle is not easy to control, and the installation error is large
