Reel rotating speed synchronizing device of pathology slicing knife impact machine

Abstract

The invention discloses a reel rotating speed synchronizing device of a pathology slicing knife impact machine. The device comprises an impact machine, a workbench and a blade belt formed by connecting slicing knives one by one, the impact machine is arranged on the workbench, servo motors are fixedly installed at the two ends of the workbench correspondingly, and the servo motors are in transmission connection with reels through transmission devices. A limiting device and a guiding device are further fixedly installed at the top of the workbench, the blade belt passes through the limiting device and the guiding device, the two ends of the blade belt are wound around the reels on the two sides, the impact machine is located between the limiting device and the guiding device, and the limiting device and the guiding device are located between the reels on the two sides. Sensing rods are further symmetrically installed on the front face of the workbench and linearly connected with a speedfrequency converter, and the speed frequency converter is in control connection with the servo motors. The device has the beneficial effects that the structure is simple, the convenience and the practicability are realized, and the problem of non-uniform speed of the blade belts on the two sides in the hole opening process can be perfectly solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment production, in particular to a device for synchronizing the rotation speed of a reel of a pathological slicer impactor. Background technique [0002] Pathological sectioning technique refers to taking a certain size of lesion tissue and making pathological slices with histopathological method. Usually, the lesion tissue is embedded in paraffin block, cut into thin slices with a microtome, and then stained with hematoxylin-eosin. The lesion is then further examined with a microscope. Observe and study the occurrence and development of lesions, and finally make a pathological diagnosis. Therefore, sampling is an important part of it. The quality of sampling is directly related to the quality of tissue sections, and even the final pathological diagnosis. An ideal pathological slicer is an important prerequisite for this work, so it is extremely important for the production of pathological ...

AI Technical Summary

Problems solved by technology

[0003] During the production process of the pathological slicer, the slicer needs to be perforated. In order to facilitate the collection during the perforation process, the blade belt is usually transitioned from one reel to another reel. The transition between the two reels During the process, since the actual diameter of the blade belt on the reel will change from time to time, the speed of the blade belt on both sides will be inconsistent. The current existing technology cannot solve the problem of secondary defects or high cost and complex structure.
