Abstract
The invention relates to a glass fiber cutting method and a glass fiber cutting device for preventing a glass fiber from axially traveling. A glass fiber cutting machine comprises a knife roll, a pressing roll, a rubber roll, a rubber roll pressurizing device, a pressing roll pressurizing device and a continuous long fiber bundle, wherein the rubber roll pressurizing device controls the pressure of the rubber roll on the knife roll and the pressing roll; the knife roll is driven by a power device to rotate; the pressing roll comprises a front pressing roll and a rear pressing roll which are distributed along the feeding direction of the continuous long fiber bundle; the pressing roll pressurizing device controls the pressure of the front pressing roll and the rear pressing roll on the rubber roll; the surface liner speed of the knife roll, the rear pressing roll and the front pressing roll gradually decreases; and the long fiber bundle passes through a clearance between the front pressing roll and the rubber roll, passes through a clearance between the rear pressing roll and the rubber roll and then is fed into the knife roll. The long fiber bundle which is fed into the clearance between the knife roll and the rubber roll is straightened under the action of internal tension force generated by speed difference between the front pressing roll and the rear pressing roll through a damping mechanism, and the influence on stable feeding of the continuous long fiber bundle caused by horizontal traveling of the continuous long fiber bundle on a rubber roll surface in the cutting process of the continuous long fiber bundle is prevented.
Description
Technical field
The present invention relates to a kind of the glass cutting method and the device that have circular cutting member, especially relate to a kind of the glass cutting method and the device thereof that prevent the axial migration of glass.
Background technology
Glass cutting machine as shown in Figure 1, comprise rotor 2, pressure roller 1, rubber roll 3, rubber roll pressurizing device 4 and pressure roller pressurizing device 8, rotor 2, pressure roller 1, rubber roll 3 are each other in triangle distribution, rotor 2 rotates and is with dynamic pressure roller 1 and rubber roll 3 to rotate under the driving of power set, rubber roll 3 compresses with rotor 2 and keeps certain pressure under rubber roll pressurizing device 4 acts on, pressure roller 1 compresses with rubber roll 3 and keeps certain pressure under pressure roller pressurizing device 8 acts on, continuous fiber bundle 5 first through the gap of pressure roller and rubber roll, then arrives rotor and rubber roll gap is cut into chopped strand by hobboing cutter.In continuous fiber tractotomy process, continuous fiber bundle is axially in free state, therefore left and right migration on rubber roll face at each roll shaft, sometimes take the air line, sometimes move diagonally, cause cutting fibrous bundle different in size, do not reach the effect of customized cut-off, and cause two problems:
1. along with the increase of rolling cut time, because the migration in glass bundle feeding process causes the speed of feed of each glass different, part glass gradually arches upward between pressure roller and rotor, when arching upward to a certain extent, glass bundle will be skipped rotor and cannot cut off, now need to stop glass cutting machine to run and manually cut off glass bundle, again go up glass, affect continuous seepage;
2. there is multi beam glass overlap situation about cannot cut off sometimes, need manually to cut off, affect quality product and dangerous.
Summary of the invention
The object of the invention is to overcome the weak point in prior art water, and provide a kind of can customized cut-off, can continuous seepage, not easily produce the glass cutting method and the device thereof that prevent the axial migration of glass of quality product or production efficiency because of glass migration mode.
