Abstract
The invention provides a thermoplastic fiber scattering and cutting device which is simple, easy to be adjusted and easy to be disassembled. The fiber scattering and cutting device comprises a scattering mechanism and a cutting mechanism; continuous fiber bundles are from continuous fiber shelves, pass through the scattering mechanism and the cutting mechanism in sequence to reach a double-screw extruder for uniform mixing and extrusion with molten thermoplastic polymers; and rotating speed adjusting devices are respectively arranged on two pairs of rollers. The rotating speed of fiber break rollers is faster than the rotating speed of fiber separation rollers. Two rollers of the fiber break rollers are different in rotating speed; and two rollers of the fiber separation rollers are different in rotating speed. The fiber scattering and cutting device is simple in structure; the cutting length can be adjusted and controlled by the rotating speed; and the rollers are easy to be disassembled and replaced, so that the waste time for the device work is less, and the working efficiency is high. The fiber scattering device can enable fibers to be sufficiently scattered; the fibers can be fully coated by the molten thermoplastic polymers in the screw machine; and the mechanical performance of machined products is excellent.
Description
Technical field
The present invention relates to fibrous material manufacture field, particularly relate to fibrous material process equipment.
Background technology
Due to demand that is lighter for quality, the stronger material of intensity, fibre reinforced composites are more and more applied, automotive field, space industry, industrial production, civilian production etc.
The fiber feed now used mostly is fibre bundle and cuts off rear feeding through shearing device, and because fiber is comparatively thin, the fibre bundle after cut-out, when contacting with the thermoplastic polymer of melting, not easily by fully coated, thus directly has influence on the mechanical property of product.Along with market demands are more and more higher, under equal quality, improve the intensity of material method, equipment and process are also constantly weeded out the old and bring forth the new.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple, easily adjustment, easily detachable thermoplastic fibre dispersion shearing device.
Technical scheme provided by the present invention is: a kind of fiber dispersion shearing device, comprise decentralized institution 8 and shut-off mechanism 9, continuous tow is from continuous fiber rack 1, successively after decentralized institution 8 and shut-off mechanism 9, the thermoplastic polymer of whereabouts double screw extruder 2 and melting mixes to be extruded; Wherein, decentralized institution 8 comprise rub with the hands open roller bearing seat 3 and be installed on fiber rub with the hands open roller bearing seat 3 fiber rub with the hands open cylinder 5; Shut-off mechanism 9 comprises dragging disconnected roller bearing seat 4 and being satisfied with the fiber that fiber drags disconnected roller bearing seat 4 drags disconnected cylinder 6.
Two pairs of cylinders are all rubber cylinder.
Two pairs of cylinders are provided with speed setting unit 7.
Fiber is dragged disconnected cylinder 4 rotating speed and is opened cylinder 3 rotating speed faster than fiber stranding.
Between two cylinders that disconnected cylinder 4 dragged by fiber, rotating speed is different, fiber rub with the hands open cylinder 3 two cylinders between rotating speed different.
Beneficial effect of the present invention, structure of the present invention is simple, and staple fiber ppd can be controlled by rotational speed regulation, and easily, easily change, waste time less for device work, operating efficiency is high in cylinder dismounting.Fiber can be made fully to disperse by fiber dispersion device, entering, the thermoplastic polymer institute that can fully be melted in screw machine is coated, and the mechanical property of converted products is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A kind of fiber dispersion shearing device, continuous tow is from continuous fiber rack 1, and successively after decentralized institution in apparatus of the present invention 8 and shut-off mechanism 9, the thermoplastic polymer of whereabouts double screw extruder 2 and melting mixes to be extruded.
A kind of thermoplastic fibre dispersion shearing device, comprises decentralized institution 8 and shut-off mechanism 9; Wherein, decentralized institution 8 comprise rub with the hands open roller bearing seat 3 and be installed on rub with the hands open roller bearing seat 3 fiber rub with the hands open cylinder 5; Shut-off mechanism 9 comprises the fiber dragged disconnected roller bearing seat 4 and be satisfied with to drag disconnected roller bearing seat 4 and drags disconnected cylinder 6, and two pairs of cylinders are all rubber cylinder.Two pairs of cylinders are provided with speed setting unit 7, and continuous tow is through two pairs of cylinders, and drum rotation speed can regulate; Fiber is dragged disconnected cylinder 6 rotating speed and is rubbed with the hands faster than fiber and open cylinder 5 rotating speed, and between two cylinders that disconnected cylinder 6 dragged by fiber, rotating speed is different, fiber rub with the hands open cylinder 5 two cylinders between rotating speed different.
The rotating speed that disconnected cylinder 6 dragged by fiber opens cylinder 5 faster than fiber stranding, so just plays the effect of dragging disconnected continuous tow.The rotating speed difference between two cylinders of disconnected cylinder 6 dragged by fiber, and the rotating speed that fiber is rubbed with the hands between two cylinders opening cylinder 5 is different, so just plays the effect kneading open, rub with the hands open continuous tow.
Fiber rubs that to open the speed that cylinder 5 and fiber drag between disconnected cylinder 6 relatively fixing with the hands, and the speed between each cylinder immobilizes a duty.
