Abstract

A guide member is provided so as to pass through between a first axis and a second axis formed by repeatedly arranging two blades facing each other and a space, to guide diagnostic reagent paper to be cut. Therefore, by forming the section, through which the diagnostic reagent paper passes, in a rectangular shape, the diagnostic reagent paper can be cut accurately into strips without defects in the cut strips such as bending or twisting. Further, by forming guide protrusions, which are formed on a guide member supporting a soft layer from among two guide members, along the entire length in the width direction of the guide member so as to come into line-contact with the diagnostic reagent paper, the guide protrusions do not press too hard against the soft layer and allow the reagent paper to move smoothly, and thus the diagnostic reagent paper is cut in a neat, desired form with reduced defects.

하지만, 이처럼 두 개의 롤러 사이에 진단 시약지를 삽입하여 여러 개의 스트립으로 절단하는 기존의 커팅 방식은 다음과 같은 문제가 있다.However, the conventional cutting method in which diagnostic reagent paper is inserted between two rollers and cut into several strips has the following problems.
(1) 여러 개의 가위로 한 번에 여러 개의 스트립을 자르는 것과 같이 두 개의 칼날로 진단 시약지를 자름에 따라 잘린 스트립이 어느 한쪽으로 쏠리거나 휠 우려가 있다.(1) Like cutting several strips at once with several scissors, when the diagnostic reagent paper is cut with two blades, the cut strips may be tilted to one side or bent.
(2) 또한, 진단 시약지에서 절단되는 스트립은 칼날 사이에 껴서 축이 회전함에 따라 휘거나 비틀리거나 끼는 현상이 발생하여 절단 불량으로 이어지게 된다. (2) In addition, the strip cut from the diagnostic reagent paper is caught between blades, and as the shaft rotates, bending, twisting, or jamming occurs, leading to poor cutting.
(3) 이처럼 휘거나 한쪽으로 쏠린 스트립은 진단용으로 사용하는 데는 이상이 없으나, 진단 킷과 같이 정해진 위치에 집어넣어서 사용할 때는 휘어진 스트립을 진단 킷에 집어넣기가 어렵다.(3) There is no abnormality in using the bent or lopsided strip for diagnosis, but it is difficult to insert the bent strip into the diagnostic kit when used by inserting it into a predetermined position like a diagnostic kit.
(4) 이에, 기존의 커팅 방식으로 스트립을 제작하면 이처럼 휘거나 꼬인 스트립을 사용할 수 없어 불량률이 많이 발생할 뿐만 아니라 진단 킷의 제조효율도 떨어뜨리는 한 가지 요인으로 작용한다.(4) Therefore, when a strip is manufactured by the conventional cutting method, a bent or twisted strip cannot be used, which not only causes a high defect rate, but also acts as a factor that lowers the manufacturing efficiency of the diagnostic kit.
(5) 한편, 진단 시약지는 종이처럼 딱딱한 재질로 이루어진 하드 층 위에 부직포와 같은 부드럽고 체액 등을 흡수할 수 있는 부드러운 재질로 이루어진 소프트 층이 부착되게 된다. 이에, 진단 시약지를 자를 때는 하드 층은 쉽게 잘리나 소프트 층을 제대로 잘리지 않아 불량이 발생하거나 잘리더라도 뒤틀리면서 다른 종류의 불량이 발생하기도 한다.(5) On the other hand, a soft layer made of a soft material such as nonwoven fabric capable of absorbing bodily fluids is attached to a hard layer made of a hard material such as paper for diagnostic reagent paper. Accordingly, when cutting the diagnostic reagent paper, the hard layer is easily cut, but the soft layer is not properly cut, resulting in defects, or even when cut, it is twisted and other types of defects occur.

본 발명에 따른 진단 시약지용 스트립 절단 장치는 다음과 같은 효과가 있다.The strip cutting device for diagnostic reagent paper according to the present invention has the following effects.
(1) 절단에 사용되는 두 개의 축 사이를 관통하게 가이드 부재를 장착하고, 이 가이드 부재가 진단 시약지의 양쪽 면을 지지하게 하면서 블레이드가 서로 마주하게 설치된 두 개의 칼날로 진단 시약지를 절단하여 스트립으로 자를 수 있게 구성함으로써, 진단 시약지가 통과하는 공간이 대략 직사각형 형태로 이루어지게 되어 절단된 스트립이 이탈하거나 뒤틀림이 없어 스트립의 불량을 없앨 수 있다.(1) A guide member is mounted between two shafts used for cutting, and the guide member supports both sides of the diagnostic reagent paper while cutting the diagnostic reagent paper into strips with two blades installed facing each other. By being configured to be cut, the space through which the diagnostic reagent paper passes is formed in a substantially rectangular shape, so that the cut strip is not detached or twisted, so defects in the strip can be eliminated.
(2) 이때, 진단 시약지에서 소프트 층을 지지하는 가이드 부재에 형성되는 가이드 돌기가 가이드 부재의 폭 전체에 걸쳐 형성되어 진단 시약지에 폭 방향으로 선 접촉할 수 있게 구성됨에 따라 가이드 돌기와 소프트 층 사이의 마찰을 최소화할 수 있다. 이는, 소프트 층이 가이드 부재에 눌려 원하는 속도로 진행되지 않아 원하는 형태로 절단되지 않거나, 잘린 진단 시약지가 가이드 돌기에 걸려 휘거나 정해진 방향으로 빠져나가지 못해 발생하는 등의 불량을 미리 방지할 수 있다.(2) At this time, the guide protrusion formed on the guide member supporting the soft layer in the diagnostic reagent paper is formed over the entire width of the guide member so that it can make line contact in the width direction of the diagnostic reagent paper, so that between the guide protrusion and the soft layer friction can be minimized. This can prevent in advance defects such as the soft layer not being cut in a desired shape because it does not progress at a desired speed due to being pressed by the guide member, or the cut diagnostic reagent paper being caught on a guide protrusion and being bent or not being able to escape in a predetermined direction.
(3) 이러한 상기 가이드 돌기에는 소프트 층과 마주하는 면을 반구 형태의 폭 단면을 갖도록 제작함으로써, 쉽게 단면 가공을 하면서도 진단 시약지의 불량을 현저하게 줄일 수 있다.(3) By making the surface facing the soft layer of the guide protrusion to have a hemispherical cross section, it is possible to easily perform cross-section processing and significantly reduce defects in the diagnostic reagent paper.
(4) 한편, 상기 가이드 부재는 절단되는 스트립이 제1축이나 제2축의 회전 방향으로 말려드는 것을 방지하므로, 절단된 스트립이 구부러지거나 휘는 것을 방지하여 직사각 기둥 형태의 원형대로 유지할 수 있어 절단된 스트립을 진단 킷에 투입하기가 편하다.(4) On the other hand, since the guide member prevents the strip to be cut from being rolled in the direction of rotation of the first shaft or the second shaft, the cut strip can be kept in its original form in the form of a rectangular column by preventing the cut strip from being bent or bent. It is convenient to insert the strip into the diagnostic kit.
(5) 제1축의 양쪽에서 그 길이 방향으로 위치를 조절할 수 있게 구성함으로, 제2축에 형성된 칼날과의 간격 조절이 쉬울 뿐만 아니라 정밀하고 정확하게 조절할 수 있다.(5) By configuring to adjust the position in the longitudinal direction on both sides of the first shaft, it is not only easy to adjust the distance between the blades formed on the second shaft, but also precise and accurate.
(6) 한편, 조절나사는 나사 방식으로 조절하므로, 회전량을 직선 방향으로 바꿔서 동심 조절이 이루어지게 되어 칼날의 동심 조절을 0.01㎜ 단위로도 조절할 수 있어 정밀한 동심 조절이 가능하다.(6) On the other hand, since the adjustment screw is adjusted in a screw-like manner, concentric adjustment is made by changing the amount of rotation in a linear direction, so that the concentric adjustment of the blade can be adjusted in units of 0.01 mm, enabling precise concentric adjustment.
(7) 또한, 가이드 돌기에는 표면에 나일론 코팅 처리를 함으로써, 가이드 돌기의 표면이 매끄러워 가이드 부재를 오랫동안 사용하더라도 쉽게 파손되거나 부서지지 않아 내구성을 높이면서도 품질 불량이 발생하는 것을 방지할 수 있다.(7) In addition, by applying a nylon coating to the surface of the guide projection, the surface of the guide projection is smooth, so that the guide member is not easily damaged or broken even when used for a long time, thereby increasing durability and preventing quality defects.

제1축(200')과 제2축(200")은, [도 1] 내지 [도 3]과 같이, 양단을 상술한 프레임(100)에 제자리 회전할 수 있게 장착하고, 외주에는 하나의 진단 시약지(10)를 한 번에 여러 개의 스트립(11)으로 자를 수 있게 구성한다. As shown in [Figs. 1] to [Fig. 3], both ends of the first shaft 200' and the second shaft 200" are rotatably mounted on the frame 100 described above, and a single shaft is attached to the outer circumference. The diagnostic reagent paper 10 is configured to be cut into several strips 11 at a time.
여기서, 이들 제1축(200')과 제2축(200")은 같은 구성이므로, 제1축(200')을 기준으로 설명하고, 제2축에 관해서는 그 상세한 설명을 생략한다. 또한, 상기 제1축(200')과 제2축(200")은,[도 3]과 같이, 각각 제자리에서 회전할 수 있게 구성할 수도 있으나, 제1축(200')과 제2축(200")에 각각 서로 맞물리는 기어(220)를 장착하여 함께 동시에 회전할 수 있게 구성하는 것이 바람직하다.Here, since the first shaft 200' and the second shaft 200" have the same configuration, the first shaft 200' will be described as a reference, and the detailed description of the second shaft will be omitted. In addition, , The first shaft 200 'and the second shaft 200" may be configured to rotate in place, respectively, as shown in [Fig. 3], but the first shaft 200' and the second shaft ( 200 ") is preferably configured to rotate simultaneously by mounting gears 220 meshing with each other.
이를 위해, 상기 제1축(200')은, [도 2] 및 [도 3]과 같이, 양단에 베어링(250", 260)을 갖춰서 제자리에서 회전 지지를 받을 수 있게 장착한다. 또한, 외주에는 블레이드(211)가 마주하게 배치된 두 개의 칼날(210')과 스페이서(210")를 번갈아서 끼우고 조절 너트(230)를 체결하여 고정한다. 이때, 상기 제1축(200')에는 키 홈(280)을 형성하여 이들 칼날(210')과 스페이서(210")가 제자리 회전하지 못하게 끼워서 고정한다.To this end, the first shaft 200' is equipped with bearings 250" and 260 at both ends, as shown in [Figs. 2] and [Fig. 3], so that it can be supported for rotation in place. In addition, the outer circumference The two blades 210' and the spacer 210", in which the blades 211 are disposed facing each other, are alternately inserted and fixed by tightening the adjusting nut 230. At this time, a key groove 280 is formed in the first shaft 200' so that these blades 210' and the spacer 210" are inserted and fixed so that they do not rotate in place.
1. 칼날1. blade
칼날(210')은, [도 3] 내지 [도 5]와 같이, 디스크 형상으로 형성한다. 이때, 상기 칼날(210')은 [도 4]와 같이, 한쪽 면의 가장자리에 블레이드(211)를 형성함으로써, 제1축(200')과 제2축(200")에 각각 장착하는 칼날(210')이 가위처럼 전단력을 이용하여 진단 시약지(10)를 자를 수 있게 제작한다.The blade 210' is formed in a disk shape, as shown in [Figs. 3] to [Fig. 5]. At this time, the blade 210' is a blade mounted on the first shaft 200' and the second shaft 200", respectively, by forming a blade 211 on the edge of one side, as shown in [FIG. 4] ( 210') is manufactured so that the diagnostic reagent paper 10 can be cut using shear force like scissors.
본 발명의 바람직한 실시예에서, 상기 칼날(210')에는 블레이드(211)의 가장자리 부분에 커팅 에지(211')를 형성하여 진단 시약지(10)를 스트립(11)으로 자를 때 쉽게 자를 수 있게 구성하는 것이 바람직하다. 이때, 상기 커팅 에지(211')를 형성하는 제1각도(θ1)는 상기 블레이드(211)를 형성하는 제2각도(θ2)보다 크게 형성하여 스트립(11)으로 절단할 때 서서히 잘리면서 깨끗하게 자를 수 있게 구성한다. 여기서, 상기 제1각도(θ1)는 43~47°(가장 바람직하게는 45° 각도)로 제작하고, 상기 제2각도(θ2)는 8~12°(가장 바람직하게는 10° 각도)로 제작하는 것이 가장 바람직하다.In a preferred embodiment of the present invention, the cutting edge 211' is formed on the edge of the blade 211 on the blade 210' so that the diagnostic reagent paper 10 can be easily cut into strips 11. It is desirable to configure At this time, the first angle θ1 forming the cutting edge 211' is formed to be larger than the second angle θ2 forming the blade 211 so that when cutting into the strip 11, it is gradually cut and cut cleanly. configure to be able to Here, the first angle θ1 is made at 43 to 47° (most preferably 45° angle), and the second angle θ2 is made at 8 to 12° (most preferably 10° angle). It is most preferable to
또한, 상기 칼날(210')은, [도 5]와 같이, 중앙에는 상술한 제1축(200')에 끼울 수 있도록 장착 구멍(212)을 관통 형성하고, 이 장착 구멍(212)에는 한쪽에 상술한 키 홈(280)에 끼우는 키가 끼워질 수 있도록 또 다른 키 홈(213)을 형성한다.In addition, as shown in [Fig. 5], the blade 210' has a mounting hole 212 penetrated through the center so that it can be inserted into the first shaft 200' described above, and one side of the mounting hole 212 Another key groove 213 is formed so that the key inserted into the above-described key groove 280 can be inserted.
이처럼 이루어진 칼날(210')은, [도 4]와 같이, 블레이드(211)가 서로 마주하도록 두 개의 칼날(210')이 밀착하게 하고 그 한쪽에 후술할 스페이서(210")를 밀착하게 하여 이들 두 개의 칼날(210')과 하나의 스페이서(210")를 연속해서 상기 제1축(200')에 회전하지 못하게 끼워서 장착된다. 이에, 본 발명에 따른 칼날(210')로 진단 시약지(10)를 절단할 때는 서로 마주하는 두 개의 블레이드(211) 사이와, 블레이드(211)가 형성되지 않고 서로 마주하는 면 사이에서 스트립(11)이 잘리게 되고, 이에 스트립(11)의 양쪽이 균등한 힘으로 잘리게 되어 스트립(11)의 변형이나 휨 등을 방지할 수 있게 된다.As shown in [Fig. 4], the blades 210' formed in this way have two blades 210' in close contact so that the blades 211 face each other, and a spacer 210" to be described later is in close contact with one side thereof to Two blades 210' and one spacer 210" are successively fitted to the first shaft 200' so as not to rotate. Accordingly, when the diagnostic reagent paper 10 is cut with the blade 210' according to the present invention, the strip ( 11) is cut, and both sides of the strip 11 are cut with equal force, thereby preventing deformation or bending of the strip 11.
2. 스페이서2. spacer
스페이서(210")는, [도 3] 및 [도 4]와 같이, 블레이드(211)가 마주하게 장착된 두 개의 칼날(210')의 한쪽에 밀착하게 상기 제1축(200')에 장착된다. 즉, 블레이드(211)가 마주하게 설치된 두 개의 칼날(210')과 스페이서(210")가 하나의 단위로 해서 여러 개의 단위가 제1축(200')에 끼워져서 고정하게 된다. The spacer 210" is mounted on the first shaft 200' in close contact with one side of the two blades 210' on which the blades 211 are mounted facing each other, as shown in [FIG. 3] and [FIG. 4]. That is, the two blades 210' and the spacer 210", which are installed to face the blades 211, form one unit, so that several units are inserted and fixed to the first shaft 200'.
이때, 상기 스페이서(210")는 디스크 형상으로 제작하되, 상기 칼날(210')보다 약간 작은 지름으로 제작함으로써, 칼날(210')이 진단 시약지(10)를 자를 수 있는 공간을 확보할 수 있게 구성한다. 또한, 상기 스페이서(210")도 칼날(210')과 마찬가지로 제1축(200')에 회전하지 않게 장착해야 하므로, 장착 구멍(212)과 키 홈(213)을 형성하는데, 이들 구성은 상술한 칼날(210')에서 설명한 것과 같으므로 여기서는 그 상세한 설명을 생략한다.At this time, the spacer 210" is manufactured in a disk shape, but has a slightly smaller diameter than the blade 210', so that the blade 210' can secure a space for cutting the diagnostic reagent paper 10. In addition, since the spacer 210 "should be mounted without rotation to the first shaft 200' like the blade 210', the mounting hole 212 and the key groove 213 are formed, Since these configurations are the same as those described in the above-described blade 210 ', a detailed description thereof is omitted here.
본 발명의 바람직한 실시예에서, 상기 스페이서(210")는, [도 4]와 같이, 후술할 가이드 부재(300)를 장착할 때, 이 가이드 부재(300)가 스페이서(210") 상에 위치하도록 구성함으로써, 제1축(200')과 제2축(300")에 각각 설치된 스페이서(210") 사이에 가이드 부재(300)가 관통하게 설치되고 이 가이드 부재(300) 사이로 진단 시약지(10)가 통과하면서 스트립(11)으로 잘릴 수 있을 정도 제작하는 것이 가장 바람직하다.In a preferred embodiment of the present invention, the spacer 210" is positioned on the spacer 210" when a guide member 300 to be described later is mounted, as shown in [Fig. 4]. By configuring to do so, the guide member 300 is installed to penetrate between the spacers 210" installed on the first shaft 200' and the second shaft 300", respectively, and the diagnostic reagent paper ( 10) is most preferably manufactured to the extent that it can be cut into strips 11 while passing through.
3. 조절 너트3. Adjustment nut
조절 너트(230)는, [도 3] 및 [도 6]과 같이, 상술한 제1축(200')의 한쪽, 바람직하게는 상술한 칼날(210')과 스페이서(210")를 삽입한 상태에서 제1축(200')에 체결하여 이들 칼날(210')과 스페이서(210")가 서로 나란하게 위치하도록 지지 고정한다.As shown in [Figs. 3] and [Fig. 6], the adjusting nut 230 is one side of the above-described first shaft 200', preferably the above-described blade 210' and the spacer 210" are inserted. By fastening to the first shaft 200' in the state, these blades 210' and the spacer 210" are supported and fixed so that they are positioned parallel to each other.
특히, 상기 조절 너트(230)에는, 상술한 칼날(210')과 스페이서(210")를 가압할 수 있도록 적어도 두 개의 동심 조절 나사(231)를 갖춘다. 이는, 조절 너트(230)를 제1축(200')에 체결함에 따라 [도 6(b)]와 같이, 나사의 특성상 틈새 각(θ)이 생길 수 있고, 이는 동심 조절 나사(231)를 아무리 견고하게 체결하더라도 칼날(210')과 스페이서(210")가 동심에서 벗어날 우려가 크다. 이처럼 동심이 일치하지 않으면 유격이 발생하여 칼날(210')과 스페이서(210")가 요동하게 되어 진단 시약지(10)를 균일하게 자를 수 없거나, 자른 스트립(11)이 사이에 끼는 등 불량으로 이어질 우려가 있다. 이에, 본 발명에서는, 조절 너트(230)가 칼날(210')과 스페이서(210")에 긴밀하게 밀착하지 않더라도 이 동심 조절 나사(231)를 통해 이들 사이에 긴밀하게 밀착하게 하면서도 동심을 유지하게 함으로써, 정해진 규격대로 진단 시약지(10)를 잘라서 스트립(11)을 만들고, 자른 스트립(11)이 사이에 끼는 등의 불량이 생기지 않게 한 것이다.In particular, the adjusting nut 230 is provided with at least two concentric adjusting screws 231 to press the aforementioned blade 210' and the spacer 210". As it is fastened to the shaft 200', as shown in [FIG. 6(b)], due to the nature of the screw, a gap angle θ may occur, which means that no matter how firmly the concentric adjusting screw 231 is fastened, the blade 210' There is a high possibility that the spacer 210 "is out of concentricity. If the concentricity is not consistent, a gap occurs, causing the blade 210' and the spacer 210" to fluctuate, so that the diagnostic reagent paper 10 cannot be uniformly cut, or the cut strip 11 is caught in between. Therefore, in the present invention, even if the adjusting nut 230 does not closely adhere to the blade 210 'and the spacer 210 ", the concentric adjusting screw 231 closely adheres to them. By maintaining the concentricity while cutting, the strip 11 is made by cutting the diagnostic reagent paper 10 according to the prescribed standard, and defects such as the cut strip 11 being caught between the strips 11 are prevented from occurring.
본 발명의 바람직한 실시예에서, 상기 동심 조절 나사(231)는 적어도 두 개를 구성하되, 이웃한 두 개 사이의 간격을 일정하게 구성하는 것이 바람직하며, 가장 바람직하게는 8개의 동심 조절 나사(231)를 같은 간격으로 배치하는 것이 바람직하다. 이는, 조절 너트(230)를 돌려서 조절할 때 어느 쪽에 틈새 각(θ)이 생길지 알 수 없으므로, 동심 조절 나사(231) 사이의 간격을 좁게 배치함으로써 항상 가까이 있는 동심 조절 나사(231)를 통해 동심을 조절할 수 있게 하기 위함이다.In a preferred embodiment of the present invention, the concentric adjusting screw 231 constitutes at least two, but it is preferable to configure a constant interval between two adjacent ones, most preferably eight concentric adjusting screws 231 ) is preferably arranged at equal intervals. This is because it is not known which side the clearance angle θ will occur when adjusting by turning the adjusting nut 230, so that the concentricity can be achieved through the concentric adjusting screw 231 always close by by arranging the gap between the concentric adjusting screws 231 narrowly. in order to be able to control
이처럼 동심 조절 나사(231)를 통해 동심을 조절한 뒤에는 동심도 게이지 등을 이용하여 칼날(210')의 동심도를 확인하면서 조절해야 함은 본 발명이 속한 기술분야의 종사자라면 누구든지 쉽게 알 수 있을 것이다. 또한, 이러한 동심 조절 나사(231)는 제1축(200')의 한쪽에만 구성할 수도 있으나, 바람직하게는 양쪽에 각각 하나씩 구성함으로써, 동심을 조절할 때 양쪽에서 조절하여 쉽고 정확하게 동심 조절이 이루어질 수 있게 구성하는 것이 바람직하다.As such, after adjusting the concentricity through the concentricity adjusting screw 231, it is necessary to check and adjust the concentricity of the blade 210 'using a concentricity gauge, etc. Anyone skilled in the art to which the present invention belongs will easily know . In addition, these concentric adjustment screws 231 may be configured on only one side of the first shaft 200', but preferably by configuring one on each side, when adjusting the concentricity, concentricity can be easily and accurately adjusted by adjusting from both sides. It is preferable to configure
여기서, 미설명부호 "290"은 상술한 제1 및 제2축(200', 200")에 끼워서 사용하는 간격 조절용 스페이서로, 진단 시약지(10)의 길이에 맞춰서 칼날(210')과 스페이서(210")의 장착 개수나 위치 등을 조절할 필요가 있을 때처럼 필요할 때 삽입해서 사용한다.Here, the non-explained numeral "290" is a spacer for adjusting the distance used by being inserted into the first and second shafts 200' and 200" described above, and the blade 210' and the spacer according to the length of the diagnostic reagent paper 10.

본 발명의 [실시예 2]에 따른 진단 시약지용 스트립 절단 장치는, [도 10]과 같이, 상술한 [실시예 1]와 같은 구성이나, 제1축(200')에 그 길이 방향으로 유동할 수 있도록 구성을 추가한 점에서 차이가 있다. 이에, 여기서는 추가 구성을 중심으로 설명하고, 상술한 [실시예 1]과 같은 나머지 구성에 관해서는 그 상세한 설명을 생략한다.The device for cutting the strip for diagnostic reagent paper according to [Example 2] of the present invention has the same configuration as the [Example 1] described above, as shown in [Figure 10], but flows in the longitudinal direction of the first shaft 200'. There is a difference in that the configuration is added so that it can be done. Therefore, here, the description will focus on the additional configuration, and the detailed description of the remaining configurations, such as the above-described [Embodiment 1], will be omitted.
[실시예 2]는, [도 10]과 같이, 제1축(200')이 그 길이 방향으로 움직일 수 있게 조절하여 제1축(200')과 제2축(200")에 각각 장착한 칼날(210') 사이의 간격을 조절하여 전단 시트(10)를 더욱 잘 자를 수 있게 한 것이다.[Embodiment 2], as shown in [Fig. 10], the first shaft 200' is adjusted to be movable in its longitudinal direction and mounted on the first shaft 200' and the second shaft 200", respectively. By adjusting the gap between the blades 210', the shear sheet 10 can be better cut.
이를 위해, 상기 제1축(200')에는, [도 10]과 같이, 한쪽에 적어도 테이퍼 베어링(250')을 추가하여 제1축(200')이 길이 방향으로 움직이더라도 안정적으로 지지할 수 있게 구성한다. 이때, 상기 테이퍼 베어링(250')과 상술한 베어링(250")은 프레임(100) 안에 뒤로 밀리지 않고 견고하게 지지할 수 있게 장착하는 것이 바람직하다. 특히, 상기 제1축(200')과 테이퍼 베어링(250') 사이에는 압축 스프링(240)과 삽입함으로써, 제1축(200')을 길이방향으로 가압하면 그 반대 방향으로 반발력을 제공하여 완충 작용을 할 수 있게 구성한다. 또한, 상기 제1축(200')의 끝에는 스러스트 베어링(270)을 장착하여 제1축(200')을 지지할 수 있게 구성하고, 이 스러스트 베어링(270)은 상술한 프레임(100)에 제자리에서 회전될 수 있게 장착한 길이 조절 나사(271)에 맞닿게 구성한다.To this end, as shown in [Fig. 10], at least a tapered bearing 250' is added to the first shaft 200' so that it can be stably supported even if the first shaft 200' moves in the longitudinal direction. make up well At this time, it is preferable to mount the tapered bearing 250' and the above-mentioned bearing 250" so that they can be firmly supported without being pushed back in the frame 100. In particular, the first shaft 200' and the taper By inserting a compression spring 240 between the bearings 250', when the first shaft 200' is pressed in the longitudinal direction, a repulsive force is provided in the opposite direction to provide a buffer action. A thrust bearing 270 is mounted at the end of the first shaft 200' to support the first shaft 200', and the thrust bearing 270 can be rotated in place on the frame 100 described above. It is configured to come into contact with the length adjusting screw 271 mounted in a straight line.

At this time, the length adjustment screw 271 needs to adjust the length, that is, the need to adjust the distance between the blades 210' mounted on the first shaft 200' and the second shaft 200" described above. When there is, by turning the length adjustment screw 271, the first shaft 200' moves in the longitudinal direction and pushes the thrust bearing 270 to make the adjustment. At this time, the first shaft 200' is a compression spring. With the elastic support of 240, the length is adjusted while receiving a buffering action at all times, so that even if the blades are misaligned with each other, along with adjusting the distance between the blades 210', guide them to return to their original position through the buffering action.
이상과 같이 본 발명은 제1축이 탄성 지지를 받으면서 길이 방향으로 조절할 수 있게 장착함에 따라, 칼날의 위치 조절이 필요할 때 쉽게 조절하여 안정적으로 진단 시약지를 자를 수 있을 뿐만 아니라 탄성 지지를 받아 완충 작용이 이루어지므로 칼날을 보호하면서도 정해진 위치에서 정해진 형태로 정확하게 자를 수 있게 된다. 또한, 스러스트 베어링의 지지를 받는 축의 길이 방향으로 길이 조절을 쉽게 할 수 있게 되어 제1축과 제2축에 각각 설치된 칼날 사이의 간격이나 어긋남을 쉽게 조절할 수 있게 된다.As described above, according to the present invention, as the first shaft is mounted so that it can be adjusted in the longitudinal direction while receiving elastic support, it is not only possible to stably cut the diagnostic reagent paper by easily adjusting the position of the blade when it is necessary, but also to have a buffering action by receiving elastic support. As this is done, it is possible to accurately cut in a fixed shape at a fixed location while protecting the blade. In addition, it is possible to easily adjust the length in the longitudinal direction of the shaft supported by the thrust bearing, so that the gap or displacement between the blades respectively installed on the first shaft and the second shaft can be easily adjusted.
