案されている。[Prior art] As a rotating knife type cutting device, Japanese Patent Publication No. 61-4627
As described in Publication No. 7, "a pair of support shafts each fixed at both ends to the frame, a pair of hollow drums supported by each support and shaft through bearings, and rotating in opposite directions, A "cutting device" has been proposed that includes a pair of knives that are respectively fixed to the outer periphery of a drum and mesh with each other when both drums rotate, and a drive device that rotates both drums.

きる。According to the above-mentioned cutting device, since the supporting shaft is fixed at both ends to the pedestal, the support condition for the drum equipped with the knife can also be considered to be fixed at both ends, and the rotating shaft equipped with the conventional knife is fixed at both ends. Compared to the case where both ends are supported by a stand, the deflection of the drum can be significantly reduced and the sharpness of the knife can be improved. In addition, the inertia GD of a hollow drum equipped with a knife is the inertia GD of a solid rotating shaft equipped with a conventional knife.
Compared to Dt, it is significantly reduced under the same external size conditions. Therefore, power consumption for drum rotation can be reduced.
すなわち、ナイフの切味を駆動装置の消費動力を増大さ
せずに向上できる。That is, the sharpness of the knife can be improved without increasing the power consumption of the drive device.
［発明が解決しようとする課Ｍ］
しかしながら、上記従来の切断装置にあっては以下の如

■ドラムの回転等にともなって生ずる該ドラムの振動は
避けることができず、これがナイフの振動となり、ナイ
フの切味不良や刃こぼれの原因となる。(2) Vibration of the drum that occurs as the drum rotates cannot be avoided, and this causes vibration of the knife, causing poor sharpness and chipping of the knife.

かある。■Although grease is applied to the bearings interposed between the spindle and the drum, replenishing and replacing the bearings inside the drum requires removing the spindle from the pedestal,
It is difficult to remove the drum from the support shaft or reassemble it, and it may be difficult to ensure the lubricity of the bearing.

A cutting device comprising: a pair of knives that are fixed to the outer periphery of each drum and mesh with each other when both drums rotate; and a drive device that rotates both drums; Lubricating oil is loaded into the hollow part where it is housed.

ことを初めて見出したものである。[Function] As a result of intensive research, the present inventors have developed the above-mentioned technique in order to actually stabilize the sharpness of the knife of a cutting device in which a hollow drum equipped with a knife is supported on a fixed support shaft via a bearing. Recognizing the existence of problems ■ and ■, and solving them all at once by ``loading lubricating oil into the hollow part that accommodates the spindle and bearing of each drum.'' This is the first time I've discovered that it can be done.
すなわち、ドラムの回転等にともなってドラムに生ずる
振動は、ドラム内の潤滑油の振動減衰作用により直ちに
減衰せしめられる。したがって、ナイフの振動を抑制し
、ナイフの切味不良や刃こぼれを防止できる。That is, vibrations generated in the drum due to rotation of the drum, etc., are immediately attenuated by the vibration damping effect of the lubricating oil within the drum. Therefore, it is possible to suppress the vibration of the knife and prevent the knife from having poor sharpness or spilling of the blade.

Whether this lubricating oil is circulated or replaced periodically, it can be easily loaded into the drum through the oil filler port provided at the end of the drum, making it easy to ensure the lubricity of the bearing link. .
