Description

쉬이트(sheet)절단기 및 그 충격방지 방법Sheet cutter and its impact prevention method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 특히 펄프 건조 장치와 접속된 쉬이트 절단기의 개략적 사시도,1 is a schematic perspective view of a sheet cutter, in particular connected with a pulp drying apparatus,

제2도는 제1도의 화살표(K)방향에서 보아 재료가 직접됐을 때 절단기 드럼이 상승하는 것을 보여주는 개략적 정면도,FIG. 2 is a schematic front view showing that the cutter drum is raised when the material is directly seen in the direction of the arrow K of FIG.

제3도는 제1도의 화살표(K) 방향에서 보아 드럼이 하강할 때 이용되는 감쇠 수단을 보여주는 평면도.3 is a plan view showing the damping means used when the drum is lowered in the direction of the arrow K of FIG.

Claims (5)

펄프 건조장치에 이용된 것과 같은 쉬이트 절단기에서, 절단될 재료(M)의 집적으로 인하여 초래되는 하증의 충격을 방지하기 위한 방법에 있어서, 재료의 집적이 발생됐을 때 절단 드럼(11)이 자유롭게 상승되도록 하여 절단 드럼의 운동 에너지를 중력의 위치 에너지로 거의 변환시키는 것을 특징으로 하는 방법.In a sheet cutter such as used in a pulp drying apparatus, in a method for preventing the impact of sedimentation caused by the accumulation of the material M to be cut, the cutting drum 11 is free to freeze when the accumulation of material occurs. Causing it to rise so as to convert the kinetic energy of the cutting drum into the potential energy of gravity. 제 1항에 있어서, 하부 위치로 복귀되는 절단 드럼(11)의 하강이 별개의 감쇠장치(30)에 의해 완충되는 것을 특징으로 하는 방법.Method according to claim 1, characterized in that the lowering of the cutting drum (11) returned to the lower position is buffered by a separate damping device (30). 재료(M)를 절단하기 위한 회전 칼날(11a) 및 회전 칼날(11a)과 협동하는 대향 칼날(12)을 포함하는 쉬이트 절단기에 있어서, 절단드럼(11)의 상승이 가능하도록, 피봇지점(26a, 26b)에 피봇 가능하게 장착된 베어링 하우징(24a, 24b)을 포함하고, 절단 작업이 실행되는 동안 가동 칼날(11a)과 대향 칼날(12)사이에 재료가 집적되면 절단드럼(11)의 상승으로 인하여 절단드럼(11)의 운동 에너지가 중력장의 위치 에너지로 변환되는 것을 특징으로 하는 쉬이트 절단기.In a sheet cutter comprising a rotary blade (11a) for cutting the material (M) and an opposing blade (12) cooperating with the rotary blade (11a), the pivot point (1) can be raised so that the cutting drum (11) can be raised. Bearing housings 24a, 24b pivotally mounted to 26a, 26b, and wherein the material is integrated between the movable blade 11a and the opposing blade 12 during the cutting operation, Sheet cutters, characterized in that due to the rise the kinetic energy of the cutting drum (11) is converted to the potential energy of the gravitational field. 제 3 항에 있어서, 고정 대향 칼날(12) 설치되는 것을 특징으로 하는 쉬이트 절단기.4. A sheet cutter as claimed in claim 3, wherein a fixed opposed blade (12) is provided. 제3 또는 제 4 항에 있어서, 절단 드럼(11)의 하강을 완충시키는 적어도 한개의 감쇠장치(30)가 설치되는 것을 특징으로 하는 쉬이트 절단기.The sheet cutter according to claim 3 or 4, wherein at least one damping device (30) is provided to cushion the lowering of the cutting drum (11). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
