Licker-in micro-current leveling device of automatic cotton carding machine

Abstract

The invention discloses a licker-in micro-current leveling device of an automatic cotton carding machine. The device comprises an independent motor and a micro-current inductor; the independent motoris installed on the automatic cotton carding machine, any power supply line of the independent motor is connected with the input end of the micro-current inductor, the output end of the micro-currentinductor is connected with the input end of a main control board, the input end of the main control board is connected with the input end of a frequency converter, and the output end of the frequencyconverter is connected with the input end of a speed reduction motor of a cotton feed roller. The cotton supply roller can directly enter the licker-in through the cotton feed procedure, the licker-incan directly send cotton feed changes, and therefore the cotton feed roller speed can be accurately adjusted in time.

Description

technical field [0001] The invention relates to the field of carding machines, in particular to a licker-in micro-current leveling device for an automatic carding machine. Background technique [0002] At present, the leveling method of the carding machine is to sense the thickness of the cotton feeding roller, so as to adjust the speed of the cotton feeding roller to maintain the balance of the cotton feeding amount; If there is an error in the thickness of the sliver, correct the speed of the cotton roller to form a uniform system of the mixing ring. Then, since the cotton feeding roller passes through the licker-in roller, cylinder, doffer, and press roller, there is generally a distance of about 10m in the middle, and 10m of waste strips have been produced when the press roller detects an abnormality; and from From the confirmation of the abnormal detection to the confirmation of the adjustment of the feeding roller speed, the missing time and adjustment in the middle w...

Problems solved by technology

Then, since the cotton feeding roller passes through the licker-in roller, cylinder, doffer, and press roller, there is generally a distance of about 10m in the middle, and 10m of waste strips have been produced when the press roller detects an abnormality; and from From the confirmation of the abnormal detection to the confirmation of the adjustment of the feeding roller speed, the missing time and adjustment in the middle will increase the generation of abnormal sliver to at least 20-30m, which will inevitably increase the unevenness of its evenness and seriously affect the follow-up yarn quality

[0003] The above-mentioned existing leveling method, in addition to its poor sensitivity and action lag, also due to the complicated structure, the maintenance is inconvenient or after aging, the reference distance will change, which especially affects the sensing reference point and loses the basis for weight adjustment. The benchmark basis, resulting in a more comprehensive error
