Stretch breaking carding method and device for phloem fiber

Abstract

The invention relates to a stretch breaking carding method and a device for phloem fiber. The method of the invention comprises the following steps: (1) uniformly and flatly paving phloem fiber beams after unglued health preservation on a hemp feeding plate of a stretch breaking mechanism, and forwards conveying the phloem fiber beams through a feeding roller; (2) installing a plurality of traction units at intervals in the forward direction of the output end of the feeding roller, wherein each traction unit is provided with two synchronously rotating support rollers, in addition, the rotating speed of the support rollers of the front traction units is higher than that of the support rollers of the back traction units, at the same time, a pressurizing roller driven by the two support rollers through friction force is arranged on the top of the two support rollers so that the fiber is milled and stretched when passing each traction unit until the traction unit of the one side near the output end has the tensile failure; (3) inputting the fiber into a beam collection device for beam gathering and collection; (4) sending the fiber into a row of carding boxes provided with needle strips to be carded; and (5) merging the fiber into strips and dripping the strips into a strip forming tube. The invention can be widely used in the processing process of various kinds of phloem fiber, gramineae fiber and leaf fiber.

Description

technical field [0001] The invention relates to a bast fiber processing, in particular to a bast fiber stretching and carding method and device. Background technique [0002] In the current bast fiber, such as the dry hemp or hemp fiber produced in the hemp production process, the fiber is messy and the silk is serious. machine etc. to break and make hemp strips. During the carding process of the hemp fiber, a large number of hemp grains and hooks will be produced due to the need for repeated strong carding by the carding needles to pull the long fibers into short fibers. Not only the process flow is long like this, the fiber damage is serious, the fiber length is not easy to control, the average fiber length decreases, the short-lint rate increases, and the rate of making hemp strips is only about 50%. [0003] In order to overcome the above-mentioned problems, someone has invented an oil pulling and cutting machine, such as the Chinese patent application number 200510018...

AI Technical Summary

Problems solved by technology

In this way, not only the process flow is long, the fiber damage is serious, the fiber length is not easy to control, the average fiber length decreases, the short-lint rate increases, and the production rate of hemp strips is only about 50%.

[0003] In order to overcome the above-mentioned problems, someone has invented an oil pulling and cutting machine, such as the Chinese patent application number 200510018304.1, which adopts this method. Thoroughly, there is a problem of difficulty in drafting due to more doubling, which affects the production efficiency and the quality of fiber processing

In recent years, there have been some improved equipment, such as the Chinese patent application number 200510018308.X, which is a simple combination of the oil treatment and drawing machine and the needle carding machine. In actual production, there are still relatively serious winding and the problem of low production rate
