A cutter roll for glass fiber chopping machine

Abstract

The invention discloses a cutter roll for a glass fiber chopping machine, which comprises a roll body, a plurality of blades arranged on the outer wall of the roll body, and pressure plates arranged at both ends of the roll body for fixing the blades; the roll The body is provided with a purge channel that communicates with the outside world to facilitate the cleaning of the cutting between the blades; the purge channel includes a plurality of first radial flow channels arranged at one end of the roller body, and a plurality of first radial channels arranged at the other end of the roller body. Two radial flow channels and an axial flow channel for connecting the first radial flow channel and the second radial flow channel with the outside. In the present invention, compressed air is introduced from the center of one end of the roller body, and the gas is introduced into the axial blade grooves at both ends of the blade through the purge channel, forming a purge from both ends of the axial blade groove to the middle, preventing cutting from entering the blade space In the gaps, it can effectively prevent the knife from sticking, and at the same time, it can also reduce the temperature of the blade, prolong the service life of the blade, and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of glass fiber processing equipment, in particular to a knife roller used for a glass fiber chopping machine. Background technique [0002] The chopping machine is currently the most commonly used fiber cutting tool; the chopping machine uses the relative rotation of the knife roller and the rubber roller to cut the fiber, which has the characteristics of low energy consumption and high production efficiency. However, because the surface of the glass fiber is coated with a sizing agent, it is highly viscous when wet and slippery, sticking to the surface of the blade or filling the gap between the knife grooves, resulting in unfavorable yarn arrangement. In the actual operation process, because the blade is stuck in the knife groove, the yarn discharge is unfavorable, and the wear of the blade is aggravated at the same time. After working for several hours, it is necessary to stop the machine to replace the b...

However, because the surface of the glass fiber is coated with a sizing agent, it is highly viscous when wet and slippery, sticking to the surface of the blade or filling the gap between the knife grooves, resulting in unfavorable yarn arrangement

In the actual operation process, because the blade is stuck in the knife groove, the yarn discharge is unfavorable, and the wear of the blade is aggravated. After working for several hours, it is necessary to stop the machine to replace the blade and clean the knife roller, which seriously affects the production efficiency.
