Automatic sorting mechanism for acupuncture needles

Abstract

The invention discloses an automatic sorting mechanism for acupuncture needles. The automatic sorting mechanism mainly comprises a first-stage needle sorting wheel structure and a second-stage needle sorting wheel structure which are combined with each other, wherein the first-stage needle sorting wheel structure consists of a first needle sorting wheel and a first motor; the second-stage needle sorting wheel structure consists of a second needle sorting wheel and a second motor; the first needle sorting wheel consists of a cylindrical first barrel; a first needle sorting groove is formed on the outer edge of the first barrel along the axial direction; a first annular groove is formed on the outer edge of the first barrel along the circumferential direction; the cross section of the firstneedle sorting groove has a dovetail groove shape; the structure of the second needle sorting wheel is similar to that of the first needle sorting wheel; the second motor can be a stepping motor or aservo motor; the first needle sorting wheel and the second needle sorting wheel are arranged parallel to each other; a first bearing plate is obliquely arranged in the space between the rear half part of the first needle sorting wheel and the front half part of the second needle sorting wheel; and a first sensor for detecting the acupuncture needles is arranged at one end of the first bearing plate corresponding to the second needle sorting wheel. The automatic sorting mechanism for the acupuncture needles is reliable and stable.

Description

technical field [0001] The invention relates to automatic packaging equipment for acupuncture needles, in particular to an automatic acupuncture needle sorting mechanism, which sorts out a single acupuncture needle from a plurality of stacked acupuncture needles for automatic packaging. Background technique [0002] Acupuncture needles can be divided into copper wire winding handle needles, steel pipe handle needles and plastic handle needles from the handle structure. No matter what kind of acupuncture needles are produced, acupuncture needle products need to be packaged. In the prior art, acupuncture needles are packaged in various ways, among which there is a tube-through packaging form. This packaging form is to insert the acupuncture needle into a plastic tube, and a part of the acupuncture needle handle is exposed from one end of the plastic tube, and then a wedge-shaped plastic sheet is inserted into the exposed end of the plastic tube to clamp the needle body in pla...

AI Technical Summary

Problems solved by technology

This kind of minute needle insertion mechanism can be used to sort acupuncture needles, but in practical application, there are problems of unstable and unreliable minute needles, which are specifically manifested in the fact that sometimes multiple acupuncture needles are separated, and sometimes empty needles appear, which will inevitably affect Subsequent tube packing operation
