AI Technical Summary

Technical Problem

When cutting the can lid, the cutting position of the existing can opener is too deep, which causes the can lid to be closely combined with the can body after cutting, and cannot be taken out directly, and cannot adapt to cans of different heights and thicknesses, resulting in inconvenient and unsafe cutting.

Method used

A side can opener is designed, using tilted tray gears and helical gears, combined with elastic parts and adjustable protrusions, to realize cutting without contact between the hand and the can cover and adapt to different heights of the can cover, through the shrapnel The elastic force adjusts the contact between the knife wheel and the tank cover to ensure cutting quality and safety.

Benefits of technology

It realizes the safe and hygienic direct removal of the can lid, adapts to the cutting of cans of different thicknesses and heights, reduces the burrs after cutting, and improves the cutting quality and service life of the equipment.

Abstract

The invention discloses a can opener for cutting edges, comprising a first clamping handle and a second clamping handle, which are rotatably connected by rivets, a cutting wheel and a limiting groove are provided on the first clamping handle, a driving wheel is provided on the second clamping handle, the driving wheel can be engaged with the cutting wheel through the limiting groove, the cutting wheel comprises a fixed shaft, a cutter wheel, a supporting wheel and a round cover, an elastic member is provided between the round cover and the supporting wheel, the cutter wheel is provided with a step groove, a spring sheet is provided in the step groove, and an opening is provided on the spring sheet. The invention arranges a fillet between the tray gear and the bevel gear to reduce the cutting height; creatively changes the protrusion on the original cutter wheel into an elastically adjustable supporting wheel, which acts on cans with different edging heights, facilitates engagement during cutting, and can directly and safely take out the cut can cover to avoid contact between the hand and the can cover; the cutter wheel can be easily cut by the force of the spring sheet, and is suitable for cans with a certain material thickness, thereby easily improving the accuracy of the workpiece, making the cost lower and the cutting quality higher.
