[0001] The utility model relates to the technical field of equipment for needle tube production, in particular to an automatic needle tube sharpening machine for needle tube production. Background Art

[0002] A medical needle tube (also known as a syringe) is a common medical tool. Its main body is composed of a hollow pipe, and one end is a sharp needle tip for easy insertion into the human body. The processing method of the needle tube is to wind and weld stainless steel materials into a tubular structure, and then process one end of the needle tube into a sharp needle head by grinding.

[0003] However, when the current sharpening device sharpens the needle tube, it arranges and fixes a batch of needle tubes and then sharpens the batch of needle tubes uniformly. Since there are processing requirements for the size and slope of the needle tip, the proportion of the ground part in the whole needle tube is large, and the needle tube is in direct contact with the sharpening device, so the sharpening device will generate a large impact on the needle tube, easily causing the needle tip to deform or be directly damaged, resulting in poor current sharpening effect and high processing loss rate.
