Description
Technical field
The chopped carbon fiber that the utility model relates in carbon fiber industry is produced, and particularly relates to a kind of carbon fibre tow chopped device.
Background technology
Current carbon fiber cutting machine mainly adopts two kinds of pinch-roller type cutter head structures: a kind of is that fibre bundle is constantly wrapped on cutterhead initiatively, overstock after reaching certain thickness, tow is subject to the pressure of the pinch roller being arranged on cutterhead side, thus inner fiber is cut off, the chopped carbon fiber of cut-out drops in the middle of cutterhead; Another kind is that rubber rollers is initiatively with dynamic pressure roller and rotor to rotate under pressure, and fibre bundle is brought between the rubber rollers of rotation and rotor by the rubber rollers of rotating and pressure roller, and tow is cut off under extrusion, and the chopped carbon fiber of cut-out drops from rotor surface.During cutting carbon fiber, especially when cutting wet fiber, the chopped carbon fiber that the first cutter head structure cuts off easily is blocked in cutterhead, and the chopped carbon fiber that the second cutter head structure cuts off easily sticks on rotor, and namely two kinds of cutter head structures all exist the problem that chopped carbon fiber is difficult to drop smoothly.
Summary of the invention
The purpose of this utility model is the shortcoming and defect overcoming above-mentioned prior art, provides the carbon fibre tow chopped device that a kind of technique, structure are simple, chopped carbon fiber can be made to drop smoothly.
The utility model is achieved through the following technical solutions:
A kind of carbon fibre tow chopped device, comprise for carrying the transmission mechanism of carbon fibre tow 4, chopped body for being cut off by carbon fibre tow 4, described transmission mechanism comprises pressure roller 2 and is arranged on the rubber rollers 1 below pressure roller 2, and the external peripheral surface of pressure roller 2 and rubber rollers 1 contacts;
Described chopped body comprises rotor 3 and is arranged on the valve 5 below rotor 3, and the external peripheral surface of rotor 3 is intervally distributed with multiple blade 6, is provided with top flat 7 between blade 6, and the cutting edge of blade 6 contacts with rubber rollers 1.
Described blade 6, top flat 7, by spaced groove on rotor 3 outer circumference surface, assign on the external peripheral surface of rotor 3.
The embedding tight sheet 8 for reinforcing blade 6 is also assigned in the groove of described blade 6.
Described top flat 7 is fixed in groove by the end cap 10 being arranged on rotor 3 two ends; End cap 10 is fixed by bolt 11 and rotor 3.
The cutting edge radius of circle 1mm ~ 2mm larger than top flat 7 nose-circle radius of described blade 6.
Above-mentioned carbon fiber bundle chopped device shears the method for carbon fiber bundle, comprises the steps:
Rubber rollers 1 is rotated by driven by motor, pressure roller 2 and rotor 3 are followed rubber rollers 1 under pressure and are rotated, carbon fibre tow 4 is brought between the rubber rollers 1 of rotation and rotor 3 by the rubber rollers 1 of rotating and pressure roller 2, and under pressure, carbon fibre tow 4 is cut into chopped carbon fiber 13 by blade 6;
Top flat 7 stops chopped carbon fiber 13 to fall into gap between each blade 6, the air-flow that valve 5 blow gas simultaneously below rotor 3 is formed in blade 6 with top flat 7 gap, blow off the chopped carbon fiber 13 sticked on rotor 3 rotor 3 and dropping, and namely obtains chopped carbon fiber 13.
The utility model, relative to prior art, has following advantage and effect:
In the gap that this device prevents chopped carbon fiber from falling between (or being stuck in) blade by top flat, have employed valve to blow, and top flat is set between blade, due to the effect that valve is blown, make to form air-flow in blade and top flat gap, blow off chopped carbon fiber rotor, thus realize dropping smoothly of chopped carbon fiber.
Blade, top flat have employed the chimeric mode combined with rotor groove, install firmly, convenient disassembly, and more firm in cutting process.
This apparatus structure is simple, and cutting technique is convenient and swift, not only with low cost relative to prior art, and production efficiency is high, and technological means is simple and easy to do.
