Description

High-speed chopping machine for glass fibers

Technical Field

The invention relates to the technical field of glass fiber shearing equipment, in particular to a high-speed glass fiber chopping machine.

Background

In recent years, composite materials are widely applied to the fields of aviation, traffic, machinery, electronics, medical treatment, automobiles, chemical industry, wind power, buildings and the like, high-performance fibers are ideal reinforcements of advanced composite materials, development and application of aramid fibers, carbon fibers, glass fibers and basalt fibers play a great role in promoting development of the field of material science, and are favored by people, and the application range is continuously expanded. However, the development of high-performance fibers in China is relatively late, and the development mainly depends on import at present. Research and development and improvement of production equipment of the high-performance fiber, realization of low-cost large-scale production of the high-performance fiber, and great significance.

Ultra-short fibers generally refer to short fibers having a cut length of less than 20 mm. The characteristics of ultra-short fibers: higher strength at break and lower elongation at break; low shrinkage in boiling water or hot air; a high degree of dispersibility in media; antistatic property; low melting point composite and antibacterial. The most important quality index of ultra-short fiber products is the cut length uniformity of the fiber, so that the most important point of the equipment for producing ultra-short fiber is how to continuously, stably and accurately cut the fiber to the required fiber length. The high-performance fibers such as glass fiber, carbon fiber, basalt fiber, aramid fiber and the like are all drawn and wound into spinning cakes by a drawing machine by adopting tank furnace drawing and crucible drawing production processes, and the linear speed of the drawing machine can reach 1000-4000 m/min. Currently most fiber cutters are off-line, i.e.: the spinning cakes are transported to a chopping workshop or a station, placed on a creel, and pulled to a chopping machine after bundling to complete cutting operation, the linear speed of most of off-line chopping machines is 200-500m/min, and the production efficiency is low.

At present, most of cutting machines in the world adopt a radial cutter head and press wheel internal cutting type cutting technology, a plurality of groups of spinning cakes (usually 20-40 groups of spinning cakes) are manually bundled and then are drawn to a press wheel internal cutting type cutter head, the pressure is exerted by a press wheel to complete the cutting operation, fiber tows are bulky before entering the cutting, double filaments or super filaments are easy to appear, and the cutting length requirement cannot be guaranteed. The fiber after cutting off is deviate from the adjacent blade clearance under pinch roller extrusion and the rotatory centripetal force combined action of blade disc, and the silk that falls is poor with the radiating effect, very easily leads to the fiber silk to fuse the bonding jam, makes narrow and small sword seam plugged up, and the blade wearing and tearing aggravate increase the tool changing frequency, reduction production efficiency. Because the linear velocity of the pinch roller inscribed chopping machine is low, a tension adjusting and maintaining mechanism and a precise thread guiding system are additionally added, the complexity of a control system is increased, and the tension control precision is difficult to ensure. The loading mode of the pinch roller internal cutting type chopping machine is that a plurality of groups of spinning cakes are bundled and then manually wound by 2-3 circles of cutter heads, tension is adjusted, the pinch roller is compressed and then cutting-off operation is started, the working procedures are more, the operation path is longer, and the loading operation needs to be repeated after the spinning or the spinning cake group is replaced, so that the labor intensity is increased, and the production efficiency is reduced. In addition, the spinning cakes need to be transported to a short-cutting workshop or a station and then placed on a creel, so that the logistics transfer links are multiple, the investment of equipment personnel and tools is increased, and the space utilization rate of a factory building is reduced.
