Technical field
The chopped carbon fiber the present invention relates in carbon fiber industry is produced, and relates in particular to a kind of carbon fibre tow chopped device and cutting method thereof.
Background technology
Carbon fiber cutting machine mainly adopts two kinds of pinch-roller type cutter head structures at present: a kind of is that fibre bundle is constantly wrapped on cutterhead initiatively, overstock and reach after certain thickness, tow is subject to being arranged on the pressure of the pinch roller of cutterhead one side, thereby inner fiber is cut off, and 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 the rubber rollers that fibre bundle is rotated and pressure roller are brought between the rubber rollers and rotor of rotation, and tow is cut off under extruding, 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 is easily blocked in cutterhead, and the chopped carbon fiber that the second cutter head structure cuts off easily sticks on rotor, i.e. two kinds of problems that cutter head structure all exists chopped carbon fiber to be difficult to drop smoothly.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of technique, simple in structure, carbon fibre tow chopped device and the cutting method thereof that can make chopped carbon fiber drop are smoothly provided.
The present invention is achieved through the following technical solutions:
A kind of carbon fibre tow chopped device, comprise transmission mechanism, the chopped body for carbon fibre tow 4 is cut off for delivery of carbon fibre tow 4, the rubber rollers 1 that described transmission mechanism comprises pressure roller 2 and is arranged on pressure roller 2 belows, the external peripheral surface of pressure roller 2 and rubber rollers 1 contacts;
The valve 5 that described chopped body comprises rotor 3 and is arranged on rotor 3 belows, the external peripheral surface of rotor 3 is intervally distributed with a plurality of blades 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 surfaces, assign on the external peripheral surface of rotor 3.
In the groove of described blade 6, also assign and be useful on the tight sheet 8 of embedding of reinforcing blade 6.
Described top flat 7 is fixed in groove by being arranged on the end cap 10 at rotor 3 two ends; End cap 10 is fixing with rotor 3 by bolt 11.
The cutting edge radius of circle of described blade 6 is than the large 1mm～2mm of top flat 7 nose-circle radius.
Above-mentioned carbon fiber bundle chopped device is sheared 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 under pressure rubber rollers 1 and are rotated, carbon fibre tow 4 is brought between the rubber rollers 1 and rotor 3 of rotation 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 the gap between each blade 6, the air-flow that valve 5 blow gas of rotor 3 belows form in blade 6 and top flat 7 gaps simultaneously, the chopped carbon fiber 13 sticking on rotor 3 is blown off to rotor 3 and drops, obtain chopped carbon fiber 13.
The present invention, with respect to prior art, has following advantage and effect:
This device prevents that by top flat chopped carbon fiber from falling in the gap between (or being stuck in) blade, adopted valve air blowing, and top flat is set between blade, effect due to valve air blowing, make formation air-flow in blade and top flat gap, by the chopped carbon fiber rotor that blows off, thereby realize dropping smoothly of chopped carbon fiber.
Blade, top flat have adopted the chimeric mode combining with rotor groove, install firmly, and convenient disassembly, and also more firm in cutting process.
This apparatus structure is simple, and cutting technique is convenient and swift, not only with low cost with respect to prior art, and production efficiency is high, and technological means is simple and easy to do.
