Description

Knife sharpener

Technical Field

The utility model relates to the field of textile machinery, specifically a move grinding equipment for sword.

Background

The knife sharpener is an accessory equipment of a cellulose short fiber water flow type cutter and is used for grinding and maintaining a moving knife (fly knife) of the water flow type cutter. The grinding of the moving blade of the existing water flow cutting machine adopts a surface grinder, the moving blade is fixed by a clamp, only one moving blade (fly blade) can be ground at a time, and the grinding efficiency is low. In addition, a group of moving blades (fly blades) ground by the surface grinding machine are ground separately, so that the difference exists between every two blades, and the integral cutting effect of the cutting machine is influenced.

Disclosure of Invention

In order to solve the technical problem, the utility model aims to provide a knife sharpener capable of once grinding a plurality of moving knives, the concrete technical scheme is as follows:

a knife sharpener comprises a frame, wherein a rotating shaft is arranged on the frame, a knife rest is fixed on the rotating shaft, a plurality of knife rest seats are arranged on the knife rest, and a moving knife is fixed on the knife rest seats; the upper end of the movable knife is abutted against the grinding wheel, and the grinding wheel is fixed on an output shaft of the grinding wheel motor; the grinding wheel motor is fixed on the transverse sliding seat, a nut is arranged at the lower end of the transverse sliding seat and matched with the transverse lead screw, and a first handle is arranged at the outer end of the transverse lead screw; the transverse screw rod is fixed on the longitudinal sliding seat, the longitudinal sliding seat is fixed with the transmission chain, the transmission chain is meshed with the transmission gear, and the transmission gear is connected with the output end of the transmission motor; one end of the rotating shaft is provided with a worm wheel, and the worm wheel is meshed with the worm; the end of the worm is provided with a second handle.

And two ends of the knife rest are provided with limit switches.

The tool rest is provided with a limiting frame, the limiting frame is sleeved on the tool rest, the tool rest is provided with a screw hole, a locking bolt is screwed in the screw hole and then is abutted against the tool rest, and the locking bolt is fixed with the locking handle.

The utility model has the advantages that: the rotating shaft of the fixed knife rest can rotate, so that the angle of the movable knife edge can be flexibly changed. The fixed support can fix more than 6 moving blades and grind simultaneously. The reciprocating motion of the grinding head is controlled by a variable frequency motor, and the reciprocating speed can be adjusted according to actual conditions.
