This product has the characteristic of being used once only, and each injection needle can only be used once and is discarded immediately after use.

[0003] When manufacturing and processing the needles for disposable injection needles, it is often necessary to use needle sharpening equipment. The reciprocating movement of the movable base makes the needle contact with the grinding wheel for sharpening. However, it is rather troublesome to install some needles on the sharpening equipment now, and sometimes inaccurate placement will cause the needles to be arranged unevenly, resulting in a low yield rate of the sharpened needles. Content of the Utility Model

[0007] On the upper surface of the plate body of the needle placement plate, placement holes are uniformly arranged in the transverse direction, needle bodies are placed in the placement holes, and positioning plates are symmetrically and fixedly connected to the tops of the two side walls of the plate body of the placement plate, and positioning holes are opened in the positioning plates.

[0008] In addition, the preferred structure is that a mounting frame is fixed on one side wall of the plate body of the mounting plate, servo electric cylinders are symmetrically installed on the upper surface of the mounting frame, and a pressing frame is assembled and connected to the output end of the servo electric cylinder.

[0009] In addition, the preferred structure is that an installation groove is opened on the mounting plate, the needle placement plate is inserted at the installation groove, a pressing plate is arranged on the upper surface of the plate body of the mounting plate on one side of the installation groove, and a rubber pad is arranged on one side wall of the pressing plate.

[0010] In addition, the preferred structure is that a protective plate is fixedly connected to the top of the frame body of the pressing frame, positioning columns are symmetrically arranged at the convex blocks on both sides of the plate body of the pressing frame, and a pressing block is arranged on the top of the pressing frame

[0011] In addition, a preferred structure is that the diameter of the positioning post is the same as the aperture of the positioning hole on the positioning plate, and the positioning post can be inserted into the positioning hole of the positioning plate.

[0012] In addition, a preferred structure is that the pressing block is located above the upper surface of the other side of the mounting groove of the mounting plate away from the pressing plate, and a rubber pad is provided on the side wall of the pressing block facing the pressing plate.

[0013] The beneficial effects of the present utility model are as follows: The needle placement plate can be quickly inserted through the provided mounting plate. At the same time, with the cooperation of the provided pressing frame and the push of the servo electric cylinder, the positioning post can be inserted into the positioning hole of the positioning plate, thereby ensuring that the needle placement plate is accurately placed without shaking.
