Transverse cutting device with adjustable medical film size

Abstract

The invention discloses a medical film size-adjustable transverse cutting device which comprises a collecting mechanism, a cutting mechanism, a buffering mechanism, a feeding mechanism, a supplying mechanism and a multi-section frame, the bottom end of the cutting mechanism is composed of the frame, and the cutting mechanism comprises a bearing plate fixedly arranged on the frame; a sliding groove is fixedly formed in one side of the bearing plate, a sliding part is arranged on the sliding groove in a sliding mode, a knife rest is fixedly arranged at one end of the sliding part, a blade is detachably installed on the knife rest, and the transverse cutting size of the medical film is controlled by determining the consistent traction speed of the film and changing the falling speed of the blade. The falling speed of the blade is controlled by the servo motor, and the transmission cylinder, the rotating piece and the swinging piece are matched together, so that the falling distance of the blade is controllable, and the controllability of the falling speed is high; the feeding mechanism is provided with the standby roller, the speed of replacing the mother roll is increased, and therefore the production efficiency is improved, and the feeding precision can be guaranteed on the premise that the production efficiency is not affected.

Description

technical field [0001] The invention belongs to the technical field of film cutting, and in particular relates to a cross-cutting device with adjustable size of medical film. Background technique [0002] Medical film is a kind of silver salt photosensitive material. It is mainly divided into general-purpose (RX type) film with standard sensitivity. It is suitable for most of general photography, with moderate performance, low fog and high contrast, which can make bones, air Contrast enhancement with contrast agent. Due to its wide application range and large demand, it is often necessary to produce medical films of different specifications, and traditional equipment that can only produce a fixed size has been gradually eliminated; however, the current size-adjustable equipment often has the problem of low cutting accuracy, and Due to the inconsistent specifications of the target film, there are some problems, such as the inconsistent tension of the film that the collection...
