Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of comber, in particular to a multi-purpose cylinder suitable for comber of chemical fiber. BACKGROUND

[0002] A comber comprises a working section equipped with a plurality of (typically eight) comber heads. The comber heads perform a series of operations to form slivers from a lap. Each comber head comprises a pair of lap rollers and a feed roller which operates to feed the lap by a predetermined amount at a time. The leading end of the lap is gripped by grippers comprising a bottom gripper and a top gripper. A cylinder combs the leading end of the lap to form a mat, and the mat is moved towards a separating roller by the forward movement of the grippers. The rotation of the separating roller is reversed in accordance with the forward movement of the mat to move previously received mat (mat in front) backwards so that the trailing end of the mat overlaps with the leading end of newly combed mat (mat behind). Subsequently, the separating roller rotates forward to receive the mat from the grippers, and a top comb penetrates into the mat to comb the trailing end of the mat. The mat formed by the comber heads by repeating these operations is bundled and drawn, and then is pressed by a licker-in roller to produce slivers.

[0003] Some high-demand spinning requires high-precision comber, but such spinning is used in small amount, and it is too wasteful to produce a special comber for it, and a general comber cannot meet the requirements of comber of chemical fiber because the density of the combing teeth of the existing cylinder is fixed, and it is impossible to adjust the density of the combing teeth according to the production needs, so the comber using such cylinder can only produce one specification of slivers, and the use mode is too single.
