AI Technical Summary

Technical Problem

The grooves on the roller surface of the existing flax carding machine's feeding mechanism tend to accumulate short fibers, leading to a decrease in roller gripping force, unstable flax fiber conveying, and uneven feeding, which seriously affects the carding effect and finished product quality of the flax carding machine.

Method used

The cleaning mechanism, which uses a negative pressure module and a conical guide sleeve, automatically sucks up the hemp fibers in the roller groove. Combined with the filter assembly and the flow guiding mechanism, it achieves alternating filtration and cleaning, prevents fiber aggregation, and ensures the roller's efficient working state.

Benefits of technology

It improves the stability and reliability of the hemp feeding mechanism, reduces conveying failures caused by fiber accumulation, significantly improves the processing efficiency of hemp fibers, avoids downtime maintenance of the hemp combing machine, and ensures the combing effect and finished product quality.

Abstract

The utility model relates to a hemp feeding mechanism for a hemp carding machine, which belongs to the field of hemp spinning yarn processing and comprises a bearing main body. The conveying mechanism is arranged on the inner side of the bearing main body; the guide assembly is arranged on the upper surface of the bearing main body; the cleaning mechanism is arranged on the right side of the bearing main body and comprises a mounting box which is arranged on the right side of the bearing main body; the negative pressure module is arranged on the lower surface of the mounting box in a communicating manner; and the two pipelines are arranged on the front surface and the rear surface of the mounting box in a communicating mode correspondingly, and the other ends of the two pipelines both penetrate through the bearing body. According to the cleaning mechanism, hemp fibers accumulated in a roller groove can be automatically sucked through cooperation of a negative pressure module and a conical sleeve, the situation that the grabbing force of the roller is reduced due to short fiber gathering is prevented, it is guaranteed that the roller is in an efficient working state all the time, and conveying faults caused by fiber accumulation are reduced; and the stability and reliability of the hemp feeding mechanism are improved.
