Utility model content
Technical problem to be solved in the utility model is the immersion system providing a kind of continuous long glass fiber reinforced resin for above-mentioned prior art, structure is simple, dispersion effect when can improve roving glass fiber dipping can reduce again the transmission tension force of roving glass fiber when flooding, to improve the dipping effect of roving glass fiber simultaneously.
The technical scheme in the invention for solving the above technical problem is: a kind of immersion system of continuous long glass fiber reinforced resin, comprise machine barrel, described machine barrel inside is shaped to impregnation chamber, parallel screw is provided with in described impregnation chamber, the front end of described parallel screw is respectively arranged with the dispersion roller rotated with described screw rod, on the upside of described machine barrel, corresponding described dispersion roller offers glass entrance, on front side of described machine barrel, the front end of corresponding described dispersion roller offers glass outlet, below described dispersion roller, described glass outlet is provided with guide roller, the axis of described guide roller described dispersion roller relative to the line of described glass entrance is obliquely installed, glass completes dipping via described glass entrance through the crack between described dispersion roller, walk around described guide roller to be involved by described glass outlet.
Preferably, described dispersion roller outer peripheral face offers straight groove structure or flume structure.When two dispersion rollers make rotating Vortex with parallel screw, groove on dispersion roller outer peripheral face can make the molten resin flowing through two dispersion roller gaps form turbulent flow, thus the glass through dispersion roller gap is fully flooded, there is provided vertical, to improve the dispersion effect of roving glass fiber can to the oblique roving glass fiber passing two dispersion roller gaps simultaneously.
Preferably, described glass entrance, near the link position of described dispersion roller and described screw rod, is convenient to make glass at a certain angle through dispersion roller.
Good setting is, the angle between the line of described guide roller and described glass entrance and the axis of described dispersion roller is 30 ~ 60 °.This angle arranges and glass can be made fully to contact with molten resin, improves molten resin to the dipping effect of roving glass fiber.
Preferably, be arranged on described parallel screw front end two described in disperse the gap between roller to be 2 ~ 5mm, dispersion roller is disperseed better to roving glass fiber.
Usually, described guide roller is roller that is fixing or that rotate.
Described glass outlet outer end is also provided with outer guide roller.
The immersion system concrete operations of the continuous long glass fiber reinforced resin of the utility model are, in the impregnation chamber of machine barrel, molten resin is fed forward by homodromal parallel screw, the continuous roving glass fiber of multiply is sent in impregnation chamber by glass entrance, and through two dispersion roller cracks, two dispersion rollers make multiply roving glass fiber disperse, molten resin fully floods roving glass fiber simultaneously, involve from glass outlet after roving glass fiber after dipping is led by guide roller, derive through outer guide roller, obtain continuous long glass fiber reinforced resin and plastic.
Compared with prior art, the utility model has the advantage of: dispersion roller is arranged on parallel screw front end, by parallel screw driven rotary, without the need to extra drive source, simplify device; Roving glass fiber is with certain angle of inclination through two dispersion rollers, and dispersion roller provides the component of a part perpendicular to roving glass fiber bundle, improves the dispersion effect of roving glass fiber bundle, is conducive to the abundant dipping to roving glass fiber; In addition, what roving glass fiber bundle adopted in dipping process is through the mode of disperseing roller crack, and the transmission tension force of roving glass fiber is less.
