Device for cutting diagnostic reagent paper into strip

A device for cutting a diagnostic reagent paper into strips, which is adapted to cut the diagnostic reagent paper (10) provided to the shape of a sheet into the strips (11) at once in a transverse direction thereof, comprising:

• a frame (100);
• a first shaft (200′) having two disc-shaped knives (210′) whose blades (211) face each other and one spacer (210″) alternately fixedly fitted repeatedly thereto, without rotating, and an adjustment nut (230) fastenedly fixed to at least one side thereof to prevent the knives (210′) and the spacers (210″) from escaping therefrom;
• a second shaft (200″) having two disc-shaped knives (210′) whose blades (211) face each other and one spacer (210″) alternately fixedly fitted repeatedly thereto, without rotating, and an adjustment nut (230) fastenedly fixed to at least one side thereof to prevent the knives (210′) and the spacers (210″) from escaping therefrom;
• and a guide member (300) mounted onto the frame (100) and having a first guide member (300′) disposed on the spacers (210″) of the first shaft (200′) and a second guide member (300″) disposed on the spacers (210″) of the second shaft (200″), so that the diagnostic reagent paper (10) is supportedly guided, passes through a space between the first guide member (300′) and the second guide member (300″), and is thus cut,
• wherein as the first shaft (200′) and the second shaft (200″) are mounted on the frame (100) to rotate in place together, the knives (210″) cut the diagnostic reagent paper (10) into the plurality of strips (11) by means of the shear forces thereof, the first shaft (200′) and the second shaft (200″) each having at least two or more concentricity adjustment screws (231) fastened on an imaginary circle with respect to the center thereof to each adjustment nut (230) fastenedly fixed thereto to pressurize the knives (210′) and the spacers (210″) in the transverse direction and to thus adjust the concentricity of the knives (210′) and the spacers (210″), and the first guide member (300′) and the second guide member (300″) each has a plurality of guide bars (310) protruding therefrom and thus fitted to the spaces between the crossing knives (210′), each guide bar (310) having both rounded corners (311) on the surface facing the diagnostic reagent paper (10) passes through the space between the first guide member (300′) and the second guide member (300″), and the guide bars (310) of at least one of the first guide member (300′) and the second guide member (300″) having grooves (321) formed on given portions where the diagnostic reagent paper (10) is cut by the knives (210′) fitted to the first shaft (200′) and the second shaft (200″) to prevent the diagnostic reagent paper (10) from being pressed by the guide bars (310).
