Industrial ray detection negative film digital device

Abstract

The invention provides an industrial ray detection negative film digital device, which effectively solves the problems that the device cannot continuously acquire multiple negative films, the negative films of suitable specifications are few, a sensor has low sensitivity, the slipping transmission efficiency of a synchronous belt is low and the like through an automatic film feeding mechanism, a linkage shading device, a gear transmission device, a heat-dissipating device and a capacitance sensor. The automatic film feeding mechanism can continuously acquire multiple films; a film rubbing mechanism guarantees single film feeding at each time; an optimized digital acquisition module performs optimized improvement on the sensor and the transmission scheme; a double roller transmission mechanism is driven through gear transmission to feed the film horizontally and horizontally discharge the film after turning over by 180 degrees, so that convenience for use and high transmission reliability of the device are guaranteed; the automatic film feeding mechanism is the entrance of the film and is linked with the linkage shading mechanism; a shading plate is adjusted to shade light ray outside the film; vertical transmission of the film is guaranteed; the digital quality of the film is improved; the heat-dissipating device forms air convection in the device; and the temperature of the device is reduced.

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...
