Colored paper making machine

Colored paper making machine

Brief Introduction:The word erasure rate tester is composed of two machines, namely the colored paper making machine and the eraser machine. First, a high-grade HB pencil sharpened to 0.6MM was used to contact the test paper fixed on the drum of the test paper making machine at a 75-degree Angle under a load of 0.3kgf. Lines were drawn on the test paper at a speed of 310±10cm/min. The test paper was removed and fixed on the eraser machine. The eraser test piece was made into vertical contact with the line on the test paper. Under a standard load of 0.5KG, the back-and-forth rubbing test was conducted at a speed of 36±2CM/MIN for four times. After that, the test paper was removed and the concentration was determined with a lead core concentration meter. This machine can also be used for the eraser wear rate test.

Manual pen sharpener cutting torque testing machine

Manual pen sharpener cutting torque testing machine

Brief Introduction:The manual pencil sharpener cutting torque tester is a precision instrument specifically designed to measure the torque required by a manual pencil sharpener during the process of cutting pencils. By simulating real usage scenarios, this device can accurately detect the frictional resistance and cutting torque value between the pencil sharpener's blade head and the pencil, providing a scientific basis for product quality control, performance optimization and durability testing. It is applicable to pen sharpener manufacturers, quality inspection institutions and R&D laboratories

Lead core concentration meter | Lead core concentration testing machine

Lead core concentration meter | Lead core concentration testing machine

Brief Introduction:This machine is a kind of testing instrument used for determining the concentration of pencil leads. That is, to measure the reflected optical density of the scratch marks left by the lead core on the specified sample paper (represented by the symbol d for the reflected optical density: d=Lg1/R450, where R450 is the luminance factor of the sample's diffuse reflection of blue light with a wavelength of 450nm, that is, under certain lighting conditions, in a given direction, the luminance of the sample's reflected light to the ideal diffuse reflection luminance under the same conditions.
