Pre-needling process of acupuncture machine

Pre-needling: The main drive of the acupuncture machine drives the needle beam, the needle plate and the felting needle to reciprocate up and down through the crank-link mechanism. The fluffy web is fed into the needle punched area under the grip of the feeding curtain. When the needle plate moves downward, the felting needle penetrates the fiber web, and the fiber web abuts against the net plate. When the needle plate moves upward, the friction between the fiber web and the felting needle causes the fiber web and the felting needle to move upward together, and the fiber web is close to the stripping plate. The feed and output speeds are matched, and can be stepped intermittently or continuously. After the web passes through the acupuncture zone, it has a certain strength, density and thickness, and then it is sent to the main acupuncture.
