Description

Technical Field

[0001] The present application relates to the technical field of glass fiber chopped short-cut equipment, and in particular to an automatic yarn feeding mechanism of a continuous online short-cutting machine. Background Art

[0002] The glass fiber manufacturing process is briefly described: After the ore raw materials are formulated, they are melted into molten glass in a kiln. The glass then flows through a porous platinum bushing, where it is coated with a sizing agent by a filament oiler. The glass is then drawn into ultrafine fibers by various high-speed drawing equipment, such as a drawing machine. These fibers are wound into either direct roving or preformed yarn cakes, and are divided into offline chopped yarn and online chopped yarn. Offline chopped yarn is produced by winding preformed yarn cakes from preformed yarn cakes coated with a filament oiler through a drawing machine. These preformed yarn cakes are then combined and chopped offline. However, offline chopping requires long cycles, low efficiency, and high energy consumption. Online chopping simplifies the process of removing preformed yarn cakes. The fibers are then directly drawn and chopped from multiple bushings after being coated with a sizing agent by a filament oiler. This eliminates the need for a drawing machine, cake transfer, and offline chopping facilities required for each bushing.

[0003] One of the purposes of chopping is to cut fiberglass yarn into suitable sizes for processing into desired products. For example, the chopped fiberglass yarn segments can be added to cloth or sheet materials and then made into fiberglass cloth or sheet materials through adhesives and other raw materials. A chopper is a special equipment used to complete the chopping process of fiberglass yarn. For existing chopping equipment, please refer to:
