본 고안은 복사기의 정착압력 조절장치에 관한 것으로, 특히 정착압력을 간단용이하게 조절하여 정착성능을 향상시킬 수 있게한 정착압력 조절장치에 관한 것이다.The present invention relates to a fixing pressure adjusting device of the copier, and more particularly, to a fixing pressure adjusting device that can easily adjust the fixing pressure to improve the fixing performance.
통상의 복사기의 정착부는 제1도에 도시한 바와 같이, 히트롤(1)과 프레스롤(2)이 구비되고 히트롤(1)을 내부에 장착된 히터(3)로 가열하면서 프레스롤(2)로 가압하여 복사용지(P)에 화상을 정착시키도록 되어있다.As shown in FIG. 1, a fixing unit of a conventional copier is provided with a heat roller 1 and a press roll 2, and the press roll 2 is heated while heating the heat trol 1 with a heater 3 mounted therein. Press to press to fix the image on the copy paper (P).
이러한 정착기부에서 하측의 프레스롤(2)은 그 축(4)단부에 착설된 베어링(5)에 요홈(5a)이 형성되어 축핀(6)으로 회동가능하게 설치된 승강판(7)의 요입부(7a)가 끼워져 지지되고 그 승강판(7)의 단부에 형성된 고정공(7b)에는 인장스프링(8)의 일단이 고정되고 그 인장스프링(8)의 타단부는 상측의 고정판(9)에 고정되어 프레스롤(2)이 히트롤(1)에 탄력 접촉되게 함으로써 정착에 요구되는 압력을 유지하도록 되어 있다.In the fixing unit, the lower press roll 2 has a recess 5a formed in the bearing 5 mounted on the end of the shaft 4, and the recessed part of the elevating plate 7 rotatably installed by the shaft pin 6 is formed. One end of the tension spring 8 is fixed to the fixing hole 7b formed at the end of the elevating plate 7 and supported by the 7a, and the other end of the tension spring 8 is attached to the upper fixing plate 9. It is fixed so that the press roll 2 is elastically contacted with the heat roller 1 so as to maintain the pressure required for fixing.
그러나, 종래의 정착장치는 정착에 소요되는 압력이 인장스프링(8)의 장력에 의하여 가하여지게 되는데 인장스프링(8)의 양단이 위치 변동없이 고정되어 있기 때문에 필요에 따라 정착압력을 조절하지 못하는 문제점이 있었다.However, in the conventional fixing device, the pressure required for fixing is applied by the tension of the tension spring 8, but since both ends of the tension spring 8 are fixed without change in position, it is not possible to adjust the fixing pressure as necessary. There was this.
즉, 복사용지 두께에 따른 소요정착 압력변화를 줄 수 없을 뿐 아니라 세트조립시 발생할 수 있는 정착압력의 변동을 손쉽게 보장 할 수 없는 문제점이 있었다.That is, not only can not give a change in the required fixing pressure according to the thickness of the copy paper, but also there was a problem that can not easily guarantee the fluctuation of the fixing pressure that may occur during assembly of the set.
본 고안은 이와 같은 종래의 결함을 해소하기 위하여 안출한 것으로, 고정에 조절구를 미끄럼 직선이동 가능하게 설치하고 승강판에 일단부가 고정된 인장스프링의 타단부를 조절구의 일단부에 고정하여 조절구를 간단히 이동시킴으로써 정착압력을 간단용이하게 조절할 수 있게한 것인바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional defect, the control mechanism is installed in the fixed to the sliding linear movement to the fixed and the other end of the tension spring fixed to one end of the elevating plate fixed to the lifting plate at the end of the control It is to be able to easily adjust the fixing pressure by simply moving the bar, described in detail by the accompanying drawings as follows.
제2도 및 제3도에 도시한 바와 같이, 히트롤(1)의 하부에 프레스롤(2)이 설치되고, 승강판(7)이 프레스롤(2)의 단부에 근접하게 축핀(6)으로 축착되며, 승강판(7)의 요입부(7a)에는 프레스롤(2)의 축(4)이 베어링(5)을 개재하여 지지되고, 승강판(7)의 일단부 즉, 축핀(6)이 결합되는 단부의 반대쪽 단부에는 승강판(7)을 상향으로 탄력 지지하여 프레스롤(2)이 히드롤(1)에 탄력적으로 압착되도록 구성된 것에 있어서, 상기 히트롤(1) 상측의 고정판(9)에 직선형 안내공(9a)을 형성하고 인장코일스프링(8)의 단부가 고정되는 고정공(10a)을 가지는 조절구(10)의 상하면에는 손잡이(10b)와 안내돌조(10c)를 형성하여 그 안내돌조(10c)를 상기 고정판(9)의 안내공(9a)에 미끄럼 이동 가능하게 삽입하며, 조절구(1)의 양면에는 중간부에 돌기(11a)가 형성된 판스프링(11)을 그 양단부의 장공(11b)에 끼워지는 고정나사(12)로 각각 체결하는 한편, 고정판(9)의 안내공(9a) 양측에는 상기 판스프링(11)의 돌기(11a)가 걸려지지되는 요홈(13a)을 다수개 가지는 스토퍼(13)를 형성하고, 상기 고정판(9)은 수평기준선에 대해 소정의 경사도(α)로 기울어지게 설치한 것이다.As shown in FIG. 2 and FIG. 3, the press roll 2 is installed in the lower part of the heat roller 1, and the lifting plate 7 is close to the end of the press roll 2, and the shaft pin 6 is carried out. , The shaft 4 of the press roll 2 is supported through the bearing 5 at the recess 7a of the lifting plate 7, and one end of the lifting plate 7, that is, the shaft pin 6 At the opposite end of the end to which the coupling is coupled, the lifting plate 7 is elastically supported upward so that the press roll 2 is elastically compressed to the hydro roll 1, and the fixing plate above the heat trol 1 9) a handle 10b and a guide protrusion 10c are formed on the upper and lower surfaces of the adjusting device 10 having a linear guide hole 9a and a fixed hole 10a on which an end of the tension coil spring 8 is fixed. The guide protrusion 10c is slidably inserted into the guide hole 9a of the fixing plate 9, and the plate spring 11 having the protrusion 11a formed at the middle portion is formed on both sides of the adjusting hole 1. At both ends While each fastening with fixing screws 12 fitted in the long hole (11b), grooves (13a) on which the projection (11a) of the leaf spring 11 is caught on both sides of the guide hole (9a) of the fixing plate (9) A plurality of stoppers 13 are formed, and the fixing plate 9 is installed to be inclined at a predetermined inclination α with respect to the horizontal reference line.
이와 같이 된 본 고안은 정착압력을 변화시킬 필요가 있을때 조절구(10)를 소정각도로 경사지게 설치된 고정판(9)의 안내공(9a)을 따라 도시한 A방향으로 이동시킴에 따라 스프링(8)이 실선상태에서 가상선으로 도시한 상태로 점차 인장됨에 따라 프레스롤(2)이 히트롤(1)에 점친 큰 힘으로 압착되어 결과적으로 정착압력이 조절된다.The present invention as described above, when it is necessary to change the fixing pressure spring (8) by moving the adjuster 10 in the direction A shown along the guide hole (9a) of the fixed plate (9) installed inclined at a predetermined angle As the tension is gradually pulled from the solid state to the state shown as an imaginary line, the press roll 2 is compressed with a large force applied to the heat stroke 1, and as a result, the fixing pressure is adjusted.
이때 조절구(10)의 위치는 조절구(10)에 설치된 판스프링(11)의 돌기(11a) 및 스토퍼(13)의 요홈(13a)에 의해 결되어지며 요홈(13a)은 스토퍼(13)의 하측부에 설치되어 있으므로 조절구(10)가 이탈됨이 없이 조절된 위치에서 안정되게 유지된다. 이와 같은 과정중 판스프링(11)은 고정나사(12)에 장공(11b)으로 끼워져 있으므로 조절구(10)를 이동시킴에 따라 스토퍼(13)의 요홈(13a)에 스프링(11)의 돌기(11a)가 삽입이탈되면서 탄력적으로 원활하게 변형된다.At this time, the position of the adjusting device 10 is formed by the projection 11a of the leaf spring 11 installed in the adjusting device 10 and the groove 13a of the stopper 13, and the groove 13a is the stopper 13. Since it is installed on the lower side of the control device 10 is kept stable in the adjusted position without being separated. In this process, the leaf spring 11 is fitted into the fixing screw 12 as a long hole 11b, so that the projection 11 of the spring 11 in the groove 13a of the stopper 13 moves the control opening 10. 11a) is elastically and smoothly deformed as the insertion is released.
이상에서 설명한 바와 같은 본 고안은 조절구를 이동시킴에 따라 인장스프링을 변위시켜 정착압력을 조절할 수 있도록 되어 있으므로 환경조건 및 복사용지의 종류에 따라 정착압력을 변화시킬 수 있으며 , 세트 조립불량으로 인한 정착기의 전후부위 정착압력 차이를 손쉽게 보상하여 사용할 수 있게 됨으로써 정착성능의 저하를 예방할 수 있다.As described above, the present invention is designed to adjust the fixing pressure by displacing the tension spring by moving the control mechanism, so that the fixing pressure can be changed according to the environmental conditions and the type of copy paper. It is possible to easily compensate for the difference in the fixing pressure of the front and rear portions of the fixing unit can be used to prevent the deterioration of the fixing performance.
정착성은 정착열과 정착압력에 의하여 민감하게 영향받은 것이므로 본 고안에 따르면 정착압력을 조절할 수 있게 되어 정착성능이 크게 개선되는 것이다.Fixing property is sensitively affected by the heat of fixing and the fixing pressure, so according to the present invention it is possible to control the fixing pressure is to significantly improve the fixing performance.
