Needle feeding and head assembling mechanism of acupuncture needle automatic handle winding machine

Abstract

Provided is a needle feeding and head assembling mechanism of an acupuncture needle automatic handle winding machine. The mechanism is characterized in that workpiece clamping devices are rotatably supported on a turn table and rotate axially and horizontally, and a wire ring extends to form two metal wires; the needle feeding and head assembling mechanism comprises a drive shaft, the drive shaft is in transmission connection with a cam shaft through a rotary transmission mechanism, the cam shaft is axially vertical, and the cam shaft is provided with a cam; a machine frame of the handle winding machine is horizontally connected with a sliding base in a sliding mode; an elastic element is arranged between the sliding base and the machine frame of the handle winding machine; a needle groove is fixedly formed in the sliding base; the middle of a needle feeding swing arm is rotatably supported on the machine frame of the handle winding machine and rotates axially and vertically; one end of the needle feeding swing arm is in contact with the outline of the cam, and the other end of the needle feeding swing arm is in contact with the sliding base; the handle winding machine is provided with a first clamping jaw, a second clamping jaw and a needle pressing mechanism, wherein the first clamping jaw and the second clamping jaw are used for correspondingly clamping the two metal wires, and the needle pressing mechanism is used for pressing a needle body in the needle groove. According to the mechanism, needle feeding and head assembling are achieved, and the mechanism is ingenious, flexible in motion and stable to operate and enables the needle feeding and head assembling processes to be smooth and quick.

Description

technical field [0001] The invention belongs to the field of an acupuncture needle automatic handle winding machine, and in particular relates to a needle-feeding and head-loading mechanism of an acupuncture needle automatic handle winding machine. Background technique [0002] Acupuncture needles include a needle body (mainly a steel needle body) and a needle handle that is convenient for the user to hold the needle body. The needle body can be manipulated through the needle handle to perform treatments such as twisting, lifting and pricking on human acupuncture points. Acupuncture needles can be divided into wire-wound handle needles, steel pipe handle needles and plastic handle needles according to the structure of the needle handle. see figure 1 and figure 2 , wherein the wire-wound handle needle is formed by winding a metal wire several times (generally three times) to form a wire ring 7, and two wire segments 9, 9′ are extended on both sides of the wire ring 7, and ...
