[0002] An acupuncture needle generally consists of a needle body, a needle tip and a needle handle. The diameter of a common acupuncture needle body is between 0.16 mm and 0.45 mm. The needle body of an acupuncture needle is generally made by cutting stainless steel wire or other types of alloy wire.

[0003] For example, the needle cutting device disclosed in China Authorization Announcement No. CN 218835931 U uses an ultra-high pressure, high-speed water jet to cut the stainless steel wire, thereby making the cut surface of the stainless steel wire smooth and clean, reducing the generation of burrs, and improving the cutting quality of the stainless steel wire.

[0004] However, there are still certain problems with the above-mentioned public document. First, the document does not fully disclose the relevant mechanisms for interval cutting and the method for achieving interval cutting, that is, it does not disclose whether the water jet is turned on at intervals to achieve the purpose of cutting. If the water jet is turned on at intervals, the service life of the relevant components of the water jet cutting machine will be sharply reduced due to the characteristics of the water jet. In addition, the acupuncture needles after cutting in the document are collected by a needle feeding conveyor belt provided with a limit bar to realize the function of automatic unloading of the cut acupuncture needles. This solution also has the risk of the cut acupuncture needles being washed away by the high-pressure water jet, that is, the needle feeding conveyor belt provided with a limit bar cannot efficiently collect the cut acupuncture needles.
