Description

복사기용 클리닝 마그네틱롤의 제조방법Manufacturing method of cleaning magnetic roll for copier

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

제1도는 클리닝 마그네틱롤이 사용되어지는 복사기의 원리를 개략적으로 표시한 도면,1 schematically shows the principle of a copier in which a cleaning magnetic roll is used,

제2도는 클리닝 마그네틱롤의 사시도,2 is a perspective view of a cleaning magnetic roll,

제3도는 클리닝 마그네틱롤의 제조에 사용되는 자석수지 판재의 성형 상태를 설명한 도면.3 is a view for explaining the molding state of the magnet resin plate used in the production of the cleaning magnetic roll.

Claims (2)

한쌍의 압연로울러(8)(8′)에 의해 기계배향시킨 수지 압연자성판(11)을 원통상 롤(12)로 권회하며, 이를 사각몰드로 가압하여 측면에서보아 사각형상 자성체(13)로 성형하고, 사각형 자성체 중심부를 길이 방향으로 절단하여 복수개의 자성체(14)(14′)로 형상하여, 절단된 자성체의 대칭부면이 상호 맞닿도록 반대로 위치한후 압착하고, 압착된 4각형 자성체(13)를 소정가공에 의해 내부가 중공(中公)인 원통상 자성체(13)로 형성하며, 롤의 중공부내로 심재(心材)(17)를 삽착하여된 복사기용 클리닝 마그네틱롤의 제조방법.The resin rolled magnetic plate 11 mechanically oriented by a pair of rolling rollers 8 (8 ') is wound with a cylindrical roll 12, which is pressed with a square mold to form a rectangular magnetic body 13 from the side. A rectangular magnetic body is cut in the longitudinal direction to be formed into a plurality of magnetic bodies 14 (14 '). The symmetrical portions of the cut magnetic bodies are placed opposite to each other, and then compressed and compressed. A method of manufacturing a cleaning magnetic roll for a copier comprising forming a cylindrical magnetic body (13) having a hollow inside by a predetermined processing, and inserting a core material (17) into the hollow part of the roll. 제1항에 있어서, 상기 복수개로 절단된 자성체를 대칭으로 되는 반대면이 상호 마주보는 상태로 소정 간격을 두고 위치하여 그 간격 중앙부로는 상기 심재(17′)를 위치하며, 계속하여 이를 사각몰드로 가압하여 자성체 및 심재를 일체로 압착하고, 상호 압착된 사각형 자성체(13′)를 기게절삭 가공하여 원통상 자성체(15′)로 형성하는 것에 의해 클리닝 마그네틱롤(1′)를 얻도록 한 것을 특징으로 하는 복사기용 클리닝 마그테틱롤의 제조방법.According to claim 1, wherein the plurality of the magnetic body is located at a predetermined interval in a state in which the opposite surfaces that are symmetrical to each other facing each other, the core portion 17 'is located in the center of the interval, and subsequently the square mold The magnetic body and the core were pressed together to press together, and the rectangular magnetic body 13 'pressed together was machined to form a cylindrical magnetic body 15' to obtain a cleaning magnetic roll 1 '. Method for producing a cleaning magnetic roll for a copier, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
