Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, specifically relating to a magnetic levitation mandrel device for an automatic sleeve of a fiber drawing machine. Background Technology

[0002] A brief introduction to the manufacturing process of glass fiber: After formulating the raw ore, it is melted into molten glass in a furnace, flows out through a porous platinum stencil, is coated with a sizing agent by a monofilament oiler, and is then drawn into ultrafine fibers by various high-speed rotating drawing equipment such as drawing machines. These fibers are either wound into direct untwisted rovings or into raw filament cakes. Several drawing and winding methods require the use of a winding bobbin to form the roving, which can be made of paper or Teflon. Currently, the drawing process has been automated with features such as automatic head loading, no-cut yarn ring loading, cutting of intermediate connecting yarns, and unloading robots, replacing manual labor. However, after the robot removes the roving, a manual person must still put the winding bobbin onto the drawing machine head for further drawing and winding. This is not only inefficient but also poses safety hazards due to human-machine collaboration, hindering the overall automated production process.

[0003] Please refer to the Chinese patent: An Automatic Loading and Unloading Mechanism for Fiberglass Drawing Machines [Application Publication No.: CN115783899 A / Application No.: 202211622113.6]. This patent adjusts the lateral distance between two electric grippers [to accommodate the diameter of the winding bobbin] through a third motor, sprocket system, and front and rear fixed seats; the upper linear module drives the electric grippers forward and backward [corresponding to the bobbin loading and unloading action and the bobbin pushing action]. The device grips the two sides of the winding bobbin with electric grippers on both sides, and then uses the axial driving force of the upper linear module to place the winding bobbin onto the support unit. Problems: 1. The gripping force and unloading force on the winding bobbin come from the clamping force of the electric grippers and the driving force of the upper linear module, respectively; this can easily damage or even destroy the winding bobbin; 2. The upper linear module and electric grippers cannot simultaneously complete the support unit process of placing the winding bobbin onto the support unit, affecting the loading efficiency.
