Description

Technical Field

[0001] The present application relates to the technical field of glass fiber chopped fiber equipment, and in particular to an online chopped fiber unit that performs unit circulation by lifting, lowering, and contracting. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and comes in many varieties. It is characterized by heat resistance, corrosion resistance, good insulation properties and high mechanical strength. It is usually used as a reinforcing material in composite materials and is widely used in national economic fields such as aerospace, transportation, mechanical electronics, and building materials.

[0003] One of the purposes of chopped glass fiber yarn is to cut the glass fiber yarn into suitable sizes for use so as to process it into the required products. For example, the chopped glass fiber yarn segments are added to cloth or sheet materials and then made into glass fiber cloth or glass fiber sheet materials through adhesives and other raw materials.

[0004] A chopper is a specialized piece of equipment used to chop glass fibers. The chopper is typically equipped with a rubber roller and a knife roller, which work together to continuously chop the glass fibers. To achieve continuous production, a chopper is typically equipped with two chopper units. When a chopper unit in normal operation requires maintenance or replacement, the two units rotate by rotating the turntable.
