[0003] The existing patent announcement number CN209243288U discloses a yarn bobbin positioning device, which includes a positioning rod, a baffle and a positioning plate supporting the positioning rod. The positioning rod is fixedly connected to the upper end surface of the positioning plate, and two baffles are provided and symmetrically arranged on both sides of the positioning rod. The positioning plate is provided with a through groove that penetrates the positioning plate along its thickness direction at the position corresponding to the baffle. The lower end surface of the baffle is penetrated by the through groove and is rotatably connected to the positioning plate. Pressure plates are respectively provided on the opposite sides of the two baffles. The pressure plates are perpendicular to the baffles and fixedly connected to the baffles. The pressure plates are arranged in the through grooves. An electric contact 1 is arranged on the back side of one side of the baffle where the pressure plate is arranged. Two limit plates are fixedly connected to the lower end surface of the positioning plate. The limit plates are arranged in parallel on the side of the baffle away from the positioning rod, and an electric contact 2 cooperating with the electric contact 1 is arranged on the side of the limit plate close to the baffle. By setting the positioning rod to a truncated cone shape, the yarn bobbin can be initially positioned on the positioning rod to prevent the yarn bobbin from swinging along the positioning rod.

[0004] When the above device is used, the yarn drum can be positioned, but the positioning is performed by sleeve clamping, and the positioning stability still needs to be improved. In view of the above problems, a yarn drum positioning mechanism is proposed. Utility Model Content
