Return pull-type decorticating machine

Abstract

A reverse drawing type decorticating machine comprises a frame, a hemp feeding channel, a decorticating roller which are installed on the frame and a power arrangement which is used for driving the decorticating roller, the reverse-drawing decorticating machine is characterized in that the decorticating roller comprises a drive decorticating roller and a driven decorticating roller, wherein the angle R between the connecting wire of the axial center which belongs to the drive decorticating roller and the driven decorticating roller and the hemp feeding channel is 30DEG C-60DEG C. The reverse drawing type decorticating machine of the invention has the advantages of ensuring safety in production, clean hemp decorticating, high efficiency, and no damage to hemp fiber.

Description

technical field [0001] The invention relates to a back-pull type hemp stripping machine, in particular to a back-pull type double-roller 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, there are two main types of back-pull stripping machines, one is the roller pressing plate type, including the stripping roller, the beating plate, the pressing plate, the power device, the frame, the hemp feeding channel, etc., such as the 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 and the pressing plate to peel off the hemp, and the efficiency is low, and the quality of peeling hemp is poor; the other is Double-drum type, including two stripping rollers, power uni...

Problems solved by technology

Structurally speaking, there are two main types of back-pull stripping machines, one is the roller pressing plate type, including the stripping roller, the beating plate, the pressing plate, the power device, the frame, the hemp feeding channel, etc., such as the 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 and the pressing plate to peel off the hemp, and the efficiency is low, and the quality of peeling hemp is poor; the other is Double-drum type, including two stripping rollers, power unit, frame, hemp feeding channel, etc., which are provided with beating boards, such as Chinese patent documents CN2672086Y and CN2491462Y, because two stripping rollers are provided, so that Both the production efficiency and the quality of hemp stripping have been improved to a certain extent, but there are still some problems as follows: Usually, technicians pay attention to the relationship between the angle between the axis line of the two stripping rollers and the horizontal line, the efficiency of hemp stripping and the quality of hemp stripping , but in the prior art, the angle between the direction of the hemp feeding channel and the line connecting the axes of the two stripping rollers is unreasonable, usually close to vertical, that is, the entering direction of the hemp stalk is perpendicular to the connection between the axes of the two stripping rollers. That is to say, the running direction of the hemp stalk in the hemp feeding channel and the two stripping rollers is the same, so it will cause the hemp stalk to run too fast under the action of the two stripping rollers during work. The residence time in the hemp machine is too short, which will affect the quality of hemp peeling, and sometimes even cause injuries to the staff holding the hemp rod, resulting in production accidents

In another part of the hemp stripping machine, the angle between the hemp feeding channel and the line connecting the axes of the two stripping rollers is too small. Slow, not only the efficiency of the hemp stripping is low, but also the hemp stays in the machine for too long, which is easy to damage the hemp fiber

[0003] In addition, in the prior art, the beating plate on the hemp-stripping roller is usually a flaky steel sheet perpendicular to the tangential direction of the surface of the de-hemping roller. On the one hand, the setting angle of the beating plate is unreasonable. The hemp rod is in vertical contact, and the impact surface is small, which affects the efficiency and quality of the hemp peeling. Moreover, the top of the beating board hits the hemp rod vertically, which will cause great damage to the hemp fiber. Set on the surface of the roller, the connection strength between the beating plate and the hemp peeling roller is low, easy to damage, and the setting angle is not easy to control, and the installation error is large
