Manufacturing method for fiber glass yarns and device therefor

Abstract

The invention discloses a manufacturing method of fiber glass yarns and a device therefor. The device comprises a frame, a cover, a feeder, a heat-melting device, a cooling yarn-formation device, an antistatic device, an expanding twister, a length-measuring device, a winding machine, a waste yarn collecting tank, a water jet injector and a control circuit. The manufacturing method comprises the following steps: the glass balls are added into a platinum-substitute crucible and electrically heated to the molten state, and then the temperature is raised until the glass balls are in the liquid state; the liquid glass flows downwards through a bushing well of the platinum-substitute crucible, is instantly cooled by the surrounding air to form fiber glass filaments, and the fiber glass filaments achieves a cooling drum and then achieves a yarn cutter to be cut off; subsequently the cut fiber glass filaments are expanded by the expanding twister to form strip-shaped yarns; and finally the strip-shaped yarns are wound to coils by the winding machine after length measurement. The fiber glass yarns manufactured by the method and the device have uniform texture and stable performance.

Description

technical field [0001] The invention relates to a method for manufacturing glass fiber wool yarn and used equipment. Background technique [0002] Glass fiber wool yarn has been widely used in interior wall decoration wall coverings, indoor waterproof materials, thermal insulation materials, friction materials and other fields. Most of the existing glass fiber yarns use high-alkali glass as raw material, which has high cost, large investment in equipment, poor product performance, poor chemical stability and low strength. [0003] Chinese patent document CN2451583Y discloses a kind of equipment for producing glass fiber fixed-length wool yarn. When this equipment is in use, glass balls are fed into the platinum-substituting crucible through the feeding hole by the automatic feeding device, and the silicon carbide rods arranged in the heating holes of the platinum-substituting crucible are energized to generate heat, and then the glass balls are heated to make the glass ball...

Problems solved by technology

However, this document requires that the height of the glass liquid level in the crucible be constant during the operation of the equipment. This requirement is not easy to achieve. In addition, when the glass filament moves on the drum with the rotation of the drum, once it breaks at the lower or front part, sometimes it will If it falls off, it must be shut down and rebooted
