Cutting device of phloem fiber

Abstract

The invention relates to a cutting device of phloem fiber, which is characterized in that the cutting device comprises a reverse U-shaped machine frame, one side of the machine frame is provided with a motor, the motor drives a group of worm and gear mechanisms through a transmission mechanism, worm wheels in the worm and gear mechanisms are coaxially connected with a crank disc of a crank connecting rod mechanism, a connecting rod is eccentricly connected on the crank disc, the other end of the connecting rod is connected with a cutter, the cutter spans between two vertical beams of the machine frame and is movably supported on the cross beam of the machine frame, the cutter is provided with a guide block and a guide groove in inclined movement correspondingly to the cross beams of the machine frame, both sides of the machine frame under the cutter are respectively provided with a material inlet support plate and a material outlet support plate, a cutter falling groove right aligned with the cutter is connected between the material inlet support plate and the material outlet support plate, and a hard pad block is arranged in the cutter falling groove. When the device provided by the invention is used for cutting the phloem fiber, the time and the labor can be saved, the cutting length required by the technology can be realized, the manual operation error can be reduced, and the production efficiency is high.

Description

technical field [0001] The invention relates to a fiber cutting device, in particular to a bast fiber cutting device. Background technique [0002] The traditional method of cutting bast fibers of hemp is generally cut manually. During the operation, one person stands on the side of the guillotine and holds the hemp bundle, and sends the hemp bundle under the guillotine; another person holds the guillotine and sends it to the guillotine; Stand on the other side of the guillotine and tie. However, this method not only requires a lot of labor, but also takes a long time. For the operator, the long-term bending action and the hemp-cutting action are repeated continuously, which is not only labor-intensive, but also causes visual fatigue, and it is difficult to accurately Controlling the cutting length will also seriously affect the processing quality of the subsequent process. Therefore, realizing the cutting of mechanized hemp fiber is an active field of people's development...

AI Technical Summary

Problems solved by technology

It has several problems: first, the mechanism is too complicated, and the cutting is not easy to control; second, the hemp fiber is easy to wrap around the machine, and the unwinding is too complicated; third, when it comes to cutting the hemp tip and hemp root, it is unsafe to use and inconvenient to operate

However, if the equipment with these parameters is used to cut bast hemp fibers, the stroke of the slider is small, the shear length, shear width and shear thickness are obviously too small, and the quality of the cut hemp is unstable, the labor intensity is large, and the application Limited range and other shortcomings, so it has not been widely used in production

The ultra-short cutting machine produced by DM&E in the United States has a cutting length of only 3-200mm. Because the cutting length range is too short, it is obviously difficult to meet the production requirements for cutting various bast fibers.
