Industry radiographic inspection negative film digitalizer

Abstract

The invention provides an industry radiographic inspection negative film digitalizer. The problems that the device can be used for few negative film standards, the degree of automation of a shading device is low, a driving chain is too long, the transmission efficiency is low, the negative film is scratched through scanning, the adjusting time of a light path is long and the like can be solved through a multi-length standard feeding mechanism, an automatic shading device, a simplifying gear driving deice, a whole shaft driving rubber roll, a multi-degree of freedom light path adjusting device and the like. The multi-length-standard feeding mechanism can realize the continuous collection of the negative films and is suitable for the negative films with the multi-length standard; the automatic shading device can automatically adjusting the width of black-out cloth through the width of input negative film; the multi-degree of freedom light path adjusting device can realize the adjustment of the light path on multiple degree of freedoms; the multi-length-standard automatic feeding mechanism is an inlet of each negative film, the black-out cloth is automatically adjusted to shade the rays arranged outside the negative films, and the negative films are perpendicularly delivered, and meanwhile, the digitized quality of the negative films is improved.

Description

【Technical field】 [0001] The invention relates to an industrial digitization device, in particular to an industrial radiation detection film digitization device. 【Background technique】 [0002] Chinese Patent Publication No. CN101178369 discloses a digitizing device for industrial radiographic detection films. The length of the device is too long, the proportion of the shape is out of balance, and it is inconvenient to operate. There is no film guide in the process of film entering the transmission mechanism, which causes the deflection during film transmission to affect the digitization effect. ; When the film passes through the arc-shaped guide plate and is sent out of the device, the film rubs against the guide plate, causing scratches to appear on the surface of the film. Chinese Patent Publication No. CN101762615A discloses a digital device for industrial radiography detection film, which solves the above problems, but the film feeding mechanism can only advance a singl...

[0002] Chinese Patent Publication No. CN101178369 discloses a digitizing device for industrial radiographic detection films. The length of the device is too long, the proportion of the shape is out of balance, and it is inconvenient to operate. There is no film guide in the process of film entering the transmission mechanism, which causes the deflection during film transmission to affect the digitization effect. ;When the film passes through the arc-shaped guide plate and is sent out of the device, the film rubs against the guide plate, causing scratches on the surface of the film

Chinese Patent Publication No. CN101762615A discloses a digital device for industrial radiography detection film, which solves the above problems, but the film feeding mechanism can only advance a single sheet manually, and the degree of automation is low; the transmission in the digital acquisition module adopts belt transmission, and the transmission ratio is not high. Stable and low transmission efficiency; sensor sensitivity is low, and the trigger method is easy to cause scratches, wear and other damage to the film; no heat dissipation device; the applicable film specifications are few, which affects the popularization and application of digital devices; device fault tolerance is poor, and there is no fault prompt

Chinese Patent Publication No. CN102590240A discloses a digital device for industrial radiographic detection film, which solves the above problems, but the device is suitable for a small number of film length specifications; the shading device needs to be adjusted manually, which is inefficient and low in automation; the transmission chain is lengthy and the transmission efficiency is low. Low, high noise; the output pair rollers cause slight scratches to the film, which cannot guarantee the non-damage to the film; the manual optical path adjustment device has less freedom of adjustment and takes a long time to adjust
