Description

Double-guide-rail reciprocating type metal fiber collecting device

Technical Field

The invention relates to the field of metal fibers, in particular to a double-guide rail reciprocating type metal fiber collecting device.

Background

The metal fiber is a novel high-efficiency high-quality functional material developed in the later 70 th century, has good electrical conductivity, thermal conductivity, wear resistance, high elasticity, high strength and sinterability, and meanwhile has softness and spinnability of the nonmetal fiber, and is widely applied to general industrial departments of chemical industry, machinery, spinning, metallurgy, construction and the like, and has important application in the fields of aerospace, nuclear industry, military and the like. Because of the great difficulty of metal fiber manufacturing technology and complex process, only a few countries in the world currently walk in the front of the world in the mass production of metal fibers. In recent years, as the requirements on various performances of metal fibers are higher and higher, the manufacturing method of the metal fibers is also continuously perfected, and the currently used manufacturing methods of the metal fibers mainly comprise a melt drawing method, a drawing method and a cutting method. Among them, the most widely used is the cutting method.

In the process of preparing metal fibers by the cutting method, milling, turning, shearing, scraping, etc. may be classified according to the cutting method. The multi-tooth cutting method of expanding the multi-tooth cutter with a large blade inclination angle can be utilized, and a plurality of continuous fine metal fibers can be obtained simultaneously by utilizing the chip separation effect of the multi-tooth cutting method, so that the multi-tooth cutting method becomes a current application hot spot. However, in the process of turning a large amount of metal fibers by using a multi-tooth cutter, automatic continuous and efficient collection of the fibers is a problem to be solved urgently. Most of the existing collecting methods require operators to manually collect the metal fibers near the knife tip for high-speed cutting while turning the metal fibers by using a multi-tooth cutter, so that the efficiency is low, the labor cost is high, and the danger is high. For this purpose, patent application No. Xiong Wenpeng et al (application No. CN 201510218460.6) discloses a device for continuously collecting electrostatic spinning fibers, which uses the driving force of a fan and a nozzle to spray electrostatically atomized polymer fluid onto a cylindrical fiber receiver, and uses a motor to drive the fiber receiver to continuously roll, thereby realizing continuous automatic collection of the electrostatic spinning fibers. Patent application of Mivictory et al (publication No. CN 103981579A) discloses an electrostatic spinning collecting device and an electrostatic spinning apparatus having the device, wherein the device utilizes charged jet flow to split and shape fibers, and hangs the fibers between two parallel plates, and then a rotatable collector is utilized to realize directional collection of electrostatic spinning. However, such a method uses the spray characteristics or electric field characteristics of the electrospinning to realize automatic collection thereof, and is only applicable to the field of electrospinning, but is not applicable to the field of collection of metal fibers which do not have such characteristics.
