Fiber shearing device

Abstract

The invention discloses a fiber shearing device. An inlet of a conveying pipeline (5) aligns to an outlet of a guider (9), and a movable shearing tool (7) is mounted on a rotary shaft of a motor (3),arranged between the guider (9) and the conveying pipeline (5) and close to the outlet of the guider (9). The fiber shearing device is long in service life, high in production efficiency, low in production cost and labor intensity. Long fibers can be sheared into short fibers of a certain length, shearing efficiency is improved and abrasion of the movable shearing tool is reduced.

Description

technical field [0001] The invention relates to a shearing device, in particular to a fiber shearing device. Background technique [0002] At present, when cutting silky and flexible fibers such as glass fiber, chemical fiber, polypropylene fiber, cotton fiber, polyester and acrylic fiber, manual cutting or mechanical cutting is often used. The manual cutting method has low efficiency, high labor intensity and poor cutting accuracy. However, the fiber shearing machine used in the mechanical cutting method is generally complex in structure, single in function, high in cost, and high in production cost. Most of the shearing knives used are rotary twisting knives. The use cost of the shearing machine is increased, and during the cutting process, the fiber is prone to slipping, which reduces the cutting accuracy. For example, glass fiber reinforced thermoplastic composite panels commonly used in domestic and foreign automotive interiors, referred to as GMT panels, are processe...

AI Technical Summary

Problems solved by technology

[0003] Because the speed of the shearing roller is relatively fast, the friction between it and the rubber wheel is relatively serious, causing the blade on the roller to wear faster, and the blade needs to be changed every two hours, which reduces the processing efficiency and increases Increased production costs, but also increased the labor intensity of workers
