Description

Technical Field

[0001] The utility model relates to the technical field of printer film feeding, in particular to a positioning film feeding structure for a medical printer. Background Art

[0002] As an important part of modern medical imaging technology, the development of medical film printers is closely linked to the evolution of medical imaging and digital image processing technology. Since the widespread use of X-ray technology in the mid-20th century, the traditional way of recording medical images is to directly expose the analog signals generated by X-ray, CT, MRI and other equipment on photosensitive film, and then form a visible image through chemical development and fixing processes. However, with the advancement of computer technology and digital imaging technology, medical imaging has gradually been digitized.

[0003] Since the 1990s, digital radiography (DR) systems have gradually replaced traditional screen-film systems, generating a large amount of digital image data. In order to meet the demand for high-quality image output in clinical diagnosis, medical film printers have emerged, which can accurately print digital medical image data stored in PACS (Picture Archiving and Communication System) onto special photosensitive films, realizing the conversion from digital to analog.

[0004] In the traditional film printing process, the film feeding link often leads to reduced printing quality or film waste due to factors such as inaccurate positioning and unstable feeding. Therefore, it is necessary to propose a positioning film feeding structure for a medical printer. Utility Model Content

After the forward and reverse motors are started, the output shafts of the forward and reverse motors drive the threaded rods to rotate, driving the moving block to move, and then driving the film above it to move. The limit rods prevent the moving block from rotating when it moves.

[0011] Preferably, the stabilizing movable assembly comprises sliding blocks fixedly mounted at both ends of the moving block, and a pair of adjacent sides of the fixed rails are symmetrically provided with sliding grooves, and the sliding blocks are slidably arranged in the sliding grooves;

[0013] It is used to ensure the stability of the moving block when it moves. When the moving block moves, the sliding block slides in the sliding groove. When the sliding block slides, the rotating ball rotates stably in the rotating groove, thereby ensuring the stability of the moving block when it moves.

[0014] Preferably, the top of the moving block is at the same height as the top of the mounting block, and the top of the horizontal end of the slide rail is at the same height as the top of the moving block.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a stable movable component, when the moving block moves, the sliding block slides in the sliding groove, and when the sliding block slides, the rotating ball rotates stably in the rotating groove, thereby ensuring the stability of the moving block when moving.

[0017] 2. By setting up a driving component, after the forward and reverse motor is started, the output shaft of the forward and reverse motor drives the threaded rod to rotate, drives the moving block to move, and then drives the film above it to move, and the limit rod prevents the moving block from rotating when it moves.
