Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glass fiber production equipment, and particularly relates to a roller type mandrel device for automatic sleeve of a drawing machine. BACKGROUND

[0002] Brief introduction of the production and manufacturing process of glass fiber: after the ore raw material formula is prepared, the ore raw material is melted into glass liquid through a kiln, flows out through a porous platinum bushing, is coated with an infiltrant by a single filament oil applicator, and is drawn into superfine fibers by various drawing equipment such as a drawing machine at high speed. There are two types of yarn packages, namely, direct untwisted roving yarn packages and raw silk cake yarn packages. Several drawing and winding methods require winding yarn packages on winding drums, such as paper winding drums or Teflon winding drums. At present, the drawing process has automatic head feeding, yarn ring cutting, intermediate connecting yarn cutting, and unloading mechanical hands to replace manual work. However, after the mechanical hand takes down the yarn package, the winding drum must be manually sleeved on the head of the drawing machine to enable drawing and winding. This not only has low efficiency, but also has safety hazards caused by human-machine cooperation, which hinders the entire automatic production process.
