Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a positioning device for winding machines. Background Art

[0002] Winding machine is a textile machinery product, mainly used for processing yarn. Its functions include changing the package to increase the yarn capacity of the yarn package, and removing defects on the yarn to improve the yarn quality. In the winding process, the positioning of the yarn bobbin is a key step, which ensures that the yarn can be stably and orderly wound on the bobbin, and facilitates the removal and placement of the yarn bobbin.

[0003] The existing patent announcement number CN207016271U discloses a bobbin positioning device for a winding machine, which includes a pressure cover, a pressure cover surface facing the end face of the small end of the bobbin is an arc surface, and a semicircular fixture is provided at the center of the arc surface, and the outer circle of the fixture matches the inner diameter of the small end of the bobbin. When the pressure cover of the traditional bobbin positioning device is pressed down, the arc surface directly presses the small end of the bobbin. Since the pressure cover is a plastic product, it is very easy to cause wear during use, resulting in problems such as inaccurate positioning of the pressure cover, shaking of the bobbin, and changes in the position of the winding coil. The utility model installs a semicircular fixture on the arc surface, so that when the pressure cover is pressed down, the semicircular fixture can smoothly slide into the inner diameter of the small end of the bobbin for automatic positioning, and the positioning is accurate and reliable. At the same time, the semicircular fixture can reduce the resistance when replacing the bobbin, which is convenient to use.

[0004] The positioning device can be installed in a winding machine to position the bobbin, but the fixing stability and the convenience of taking and placing the bobbin still need to be improved. In view of the above problems, a positioning device for a winding machine is proposed. Utility Model Content
