MH-21 Main Head Stock

Main Head Stock: includes the gear reduction unit that drives the draft system, the main motor, the fiber waste collection system, the ring rail drive, the electrical equipment. The fiber waste collecting system consists of an air suction system fan and of a manual cleaning filtering element. The ring rail drive consist of an independent motor driven by a frequency converter and electronically synchronized to the drafting bottom rollers.

SUCTION SYSTEM

Suction system is equipped with three phase, 5.5KW induction motor for fan and the manual cleaning filtering elements. Consists of a main duct supporting the extractable suction tubes. The sucked air is conveyed to the filter in the headstock.

RING RAIL DRIVE

Movement of the ring rail, balloon control rings and lappet bar is controlled by a individual 2.2KW servo motor, which is electronically synchronized with the movement of the draft rollers All the adjustments of the ring rail movement for the cop build up are carried out via keyboard (stretch, increment, cone height, bottom, etc.), even when the machine is running. System includes a device for the controlled stop of the spinning frame in case of electric power failure.

SPINDLE DRIVE

Spindle motor is a three phase, 37kw induction motor driven by a frequency converter. This system driven by a single central driving shaft, drives 48 spindles simultaneously (24 per side). This driving system is fully covered by casing, which saves cleaning over time and ensures greater safety to the operator.

CONTROL & MONITORING

The control and monitoring panel is located in the door of the electrical control board. System is equipped with a set of input, output cards to perform and control the working functions of the Ring spinning frame. User friendly keyboard and A 40X8 character wide, high contrast ,graphic LCD displays provides the below information to the operator.
