Problems solved by technology

[0007] In this way, when the angle of the knife tip becomes larger, the sharpness decreases and the cutting accuracy decreases
[0008]Furthermore, when the angle of the knife edge becomes larger, the resistance to the cutting progress of the cutting knife also increases, and as a result, especially in the case of synthetic fiber fabrics, there is still Welding problems are prone to occur due to heat generated by resistance during cutting
[0009]Furthermore, when the size of the cutting blade is shortened by grinding, the rigidity of the cutting blade is reduced, the angle of the blade tip is increased, and the resistance to cutting progress is increased, it must not If the cutter is not replaced early, there will also be problems in durability

Embodiment

[0032] figure 1 It is the overall perspective view of the automatic cutting machine, and the label 1 in the figure represents the automatic cutting machine as a whole.

[0033] In this automatic cutting machine (referred to as a cutting machine) 1, a plurality of sheet materials 4 are stacked on a flat support surface (cutting table) 3 composed of a plurality of bristle brushes 2, which are gray cloths such as clothes, and airtight The thin sheet 5 is covered, so that the thin sheet material 4 is adsorbed and fixed on the support surface 3 .

[0034] A cutting head 6 for cutting these sheet materials 4 into a predetermined shape is movably arranged in the width direction (Y-axis direction) of the cutting machine 1 on a beam 7 that moves in the longitudinal direction (X-axis direction) of the cutting machine 1. .

[0035] The basic composition of cutting head 6 is as follows: figure 2 Shown, comprise: cutting blade 8; Utilize the cutting blade vibration motor (not shown) t...

Abstract

A device for grinding a cutting blade of an automatic cutting device, which improve durability of the cutting blade and maintains the blade so that it cuts cleanly in the same manner as when it was new. The device for grinding the cutting blade (8) has contact position changing means (55) for changing the position of contact of grinding means (43a, 43b) relative to the cutting edge (8) by changing the position of a supporting shaft for rockably supporting the grinding means (43a, 43b).

Description

technical field [0001] The present invention relates to an improvement of the grinding device for the cutting blade of an automatic cutting device which continuously cuts sheet material according to a pre-programmed cutting pattern. Background technique [0002] Patent Document 1 previously proposed by the applicant of the present application is known as a grinding device for a cutting blade of an automatic cutting device. [0003] The grinding device for cutting blades described in this publication is composed of: a rotating cylinder through which the cutting blades are inserted, supports the cutting blades in a reciprocating manner, and can be rotated around an axis parallel to the reciprocating direction to change the cutting blade. direction; the grinding unit is set to be able to contact and separate from the cutting knife in the above-mentioned rotating cylinder; the sliding ring is arranged on the outer circumference of the above-mentioned rotating cylinder and can ro...
