Abstract

The invention discloses a device for detecting the on-site density of printing paper, which comprises a frame, a conveying mechanism is installed at the inner bottom of the frame, a moving mechanism is arranged on the top of the frame, and a detection mechanism is arranged at the front of the moving mechanism; frame and the first hydraulic cylinder, the upper part of the first hydraulic cylinder is provided with the first piston rod, and the upper part of the first piston rod is installed in the middle position of the bottom of the lifting frame; the four corners of the lifting frame are equipped with moving shafts, and the upper end of the moving shaft Connected with the lifting frame, the lower end of the moving shaft is a free end, and the four corners of the frame are provided with side rods at the inward facing positions, and the outer ends of the side rods are provided with guide tubes, and the moving shaft passes through the axial position of the guide tubes. The invention conveniently detects the solid density of the paper through the portable densitometer; it is convenient to slide the portable densitometer horizontally and vertically, and detects the solid density of the paper through the portable densitometer, which greatly improves the detection efficiency.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the solid density of printing paper. Background technique [0002] The basic principle of densitometer measurement is to measure the degree of blackening of photosensitive materials after exposure and development, that is, blackness. During plate making, the silver bromide on the photosensitive material is reduced to metallic silver after being developed by light, forming a certain degree of light resistance. The blackness is high, the density is high; the blackness is small, the density is low. A meter with a filter that also measures the color density of color originals. Its measurement principle is similar to the basic principle mentioned above. There are two commonly used densitometers, one is called a heavy meter, which measures the density of a liquid higher than pure water; the other is called a light meter, which measures the density of a liquid smaller than...
