Automatic knife drawing mechanism of automatic dividing and cutting machine

Abstract

The invention discloses an automatic knife drawing mechanism of an automatic dividing and cutting machine. The automatic knife drawing mechanism comprises a supporting framework, a mounting frame, a drive shaft, a plurality of hobbing cutter mechanisms, a sliding mechanism and a first motor, wherein a mould rack and a slide rail are arranged on the back surface of the mounting frame from top to bottom in sequence; each hobbing cutter mechanism comprises a pair of slide blocks, a first bearing mounted on the slide blocks, a first chain gear positioned between one pair of slide blocks, a secondchain gear, a chain, a hobbing cutter fixed shaft and a hobbing cutter; the sliding mechanism comprises a second motor, a motor mounting plate, a gear, a distance sensor and a ring sleeve, wherein oneend of the ring sleeve is mounted on the first bearing, and the other end of the ring sleeve is fixedly arranged on the front surface of the motor mounting plate; and a slide block which is in sliding fit to the slide rail is arranged on a position, which corresponds to the slide rail, on the motor mounting plate. The automatic knife drawing mechanism disclosed by the invention can realize automatic aligning of the position of a hobbing cutter, and is high in dividing and cutting precision and automation degree.

Description

technical field [0001] The invention relates to the field of automatic slitting equipment, in particular to an automatic knife-drawing mechanism of an automatic slitting machine. Background technique [0002] The slitting machine is a kind of mechanical equipment that cuts wide and large rolls of paper, film, non-woven fabrics and other materials into wide and narrow rolls of materials. It is often used in papermaking machinery, printing and packaging machinery and paper tube production. [0003] Most of the cutting knives of the current slitting machines are fixed, so they can only cut materials with a certain width, which is difficult to meet the needs of production and processing; some slitting machines have adjustable knives, but the cutting The adjustment of the knife needs to be carried out manually and cannot be calibrated, resulting in low precision and automation of cutting. Contents of the invention [0004] The technical problem to be solved by the present inve...
