Automatic cutting and smoothing mechanism

Abstract

The invention discloses an automatic cutting and smoothing mechanism. The automatic cutting and smoothing mechanism comprises a printer, wherein a lower supporting plate is arranged on the surface wall at one side of the printer; a paper outlet is formed in a position, above the lower supporting plate, on the surface wall at one side of the printer; a fixed frame is welded on a position, above thepaper outlet, on the surface wall at one side of the printer; a smoothing roller is rotatably connected on the fixed frame through a rotary shaft; the smoothing roller is in transmission connection with an electric motor inside the printer through a belt; a U-shaped frame is welded on a position, at one side of the smoothing roller, on the fixed frame; the U-shaped frame is fixedly equipped witha cutter through a telescopic air cylinder; and a cutting slot matched with the cutter for use is formed in the lower supporting plate. According to the automatic cutting and smoothing mechanism disclosed by the invention, the fixed frame is firstly arranged, and the electric motor is arranged on the fixed frame for driving the smoothing roller rotated by the electric motor; and the smoothing roller is arranged, so that printed electrocardiograph paper can be smoothed and conveyed in an auxiliary mode, and therefore, the electrocardiograph paper is conveniently observed and discharged.

Description

technical field [0001] The invention relates to the technical field of electrocardiograms, in particular to an automatic cutting and smoothing mechanism. Background technique [0002] In 1842, the French scientist Mattencci first discovered the electrical activity of the heart; in 1872, Muirhead recorded the electrical signal of the heart fluctuation. In 1885, the Dutch physiologist W. Einthoven recorded the ECG waveform from the body surface for the first time. At that time, he used a capillary electrometer, which was improved into a string galvanometer in 1910. This created the history of surface ECG recording. In 1924 Einthoven was awarded the Nobel Prize in Medical Biology. After more than 100 years of development, today's electrocardiograph is perfected day by day. Not only the record is clear, the anti-interference ability is strong, but also portable, and has the function of automatic analysis and diagnosis. The electrocardiogram records the curve of voltage changi...

AI Technical Summary

Problems solved by technology

[0003] However, there are some deficiencies in the existing electrocardiogram printers during use. The existing electrocardiogram printers simply print the electrocardiograms, lack of smoothing and automatic cutting mechanisms, and cause the electrocardiograms to be printed manually. It is more troublesome to cut off, and the ECG drawing is more curled, which is inconvenient to observe
