Problems solved by technology

When measuring this kind of angle gauge, because the diameter of the plate roll is different, it is difficult for the small arc surface to fit the outer circle of the plate roll completely, so the measured angle error is relatively large.

Embodiment

[0027] Such as image 3 As shown, a gravure squeegee angle measuring device includes a backing plate 1, a rotating arm 2, a rotating shaft 3, a casing 4, a digital display screen 5, a power supply and an angle sensor. The rotating shaft 3, the digital display screen 5, the power supply and the angle sensor are all installed in the casing 4. The digital display screen 5 and the angle sensor are all connected with the power supply, and the power supply provides power for other units. The shell 4 and the backing plate 1 can be fixedly connected by glue, or other connection methods, such as screws or bolts, can also be used. The rotating arm 2 is movably connected with the rotating shaft 3, and the rotating arm 2 can rotate around the rotating shaft 3. The angle sensor is connected with the digital display screen 5, and the digital display screen is used to display the angle value measured by the angle sensor.

[0028] The angle sensor is a displacement angle sensor, a resistiv...

Abstract

The invention relates to a gravure scraper angle measurement device. The measurement device comprises a backing plate (1), a rotating arm (2), a rotary shaft (3), a shell (4), a digital display screen(5), a power source and an angle sensor, wherein the rotary shaft (3), the digital display screen (5), the power source and the angle sensor are installed in the shell (4); the shell (4) is fixedly connected with the backing plate (1); the rotating arm (2) is movably connected with the rotary shaft (3); the digital display screen (5) and the angle sensor are connected with the power source; and in the using process of the measurement device, the backing plate (1) is tangent to a gravure roller at a scraper point, and the rotating arm (2) is parallel to a scraper. Compared with the prior art,the measurement device has the advantages of being high in precision, low in cost, wide in application range, convenient to operate and the like.

Description

technical field [0001] The invention relates to the technical field of scraper equipment for printing machines, in particular to a device for measuring the angle of a gravure scraper. Background technique [0002] Since the scraper is straight and the gravure roll is round, the conventional definition of the angle of the scraper is: the angle between the plane of the scraper and the tangent of the circle at the point where the scraper contacts the roll, as figure 1 Shown in θ. An appropriate angle of the scraper has the following advantages: first, it can reduce the wear of the scraper; second, it can use the lowest possible scraper pressure to achieve the purpose of scraping the ink; third, it can maintain the contact between the scraper and the printing to the greatest extent during the entire printing process. The contact area and pressure of the plate roller are constant to ensure the stability of the same color and color difference in the same batch. Over the years, g...
