Abstract

The utility model discloses an it puts yarn mechanism passively not have additional number of turns, mobile support above including fixed platform and locating it, mobile support is used for placing GF yarn group, still including the twizzle of locating the GF yarn group side, GF yarn group highly is h, and the high department of GF yarn group h2 is located to the twizzle. The utility model discloses an it puts yarn mechanism passively not have additional number of turns adopts the configuration mode of passive unwrapping wire, and overall structure is simple effective, only need can guarantee very little external force just can stimulate the GF yarn group rotation and put the yarn passively to can effectively avoid putting the yarn in -process and produce the additional number of turns, be favorable to the fuse -element to soak.

Description

One kind passively puts yarn mechanism without additional twist

Technical field

This utility model is related to glass fiber reinforced thermoplastics composite process units, and specifically one kind is without additional twist Yarn mechanism is put passively.

Background technology

Long glass fibres strengthens thermoplasticity moulding mixture pellet (LFT), continuous glass fibre and strengthens heat type material material and sheet material, uses Continuous glass fibre (GF), its any surface finish, surface activity are low, and heat type plastic molten mass, Newtonian fluid, non-Newtonian fluid Poor with GF wellabilities, especially domestic GF is less susceptible to infiltrate with moulding mixture molten mass, and GF is getting into head in their production processes The interior time is of short duration, makes the two be impregnated with low degree.Domestic introduction production GFRTP pellets, material strip and sheet material are adopted and are passively put Yarn form, this to put yarn mode, either interior moving back outside still moves back formula, can all produce yarn additional twist, i.e., originally in production process Carry out zero twisted yarn Jing and passively put yarn process and produce additional twist to become and have twist yarn, be so unfavorable for that GF plastic molten mass infiltrates, and And this yarn form of putting also is unfavorable for making every one thread additional twist identical.So in GFRTP, each fibre length differs, right Its power bar performance brings adverse effect.And it is for sheet material GF Yarn homogeneous are distributed and isometric also particularly significant, uneven distribution is twisted with the fingers Yarn is likely to bring some to affect on its surface smoothness.

Utility model content

Utility model purpose：In order to overcome the deficiencies in the prior art, this utility model to provide one kind without additional sth. made by twisting Degree passively puts yarn mechanism.

Technical scheme：For solving above-mentioned technical problem, one kind of the present utility model passively puts yarn mechanism without additional twist, Including fixed platform and the movable bearing support of the side of being provided thereon, movable bearing support is used for placing GF yarns group；Also include rolling into a ball side located at GF yarns The twizzle in face, GF yarns group are highly h, and twizzle is highly located located at GF yarns group h/2.

Wherein, movable bearing support includes attic base and is located therein the hollow axle in portion, and GF yarns group is on hollow axle.

Wherein, twizzle and GF yarns roll into a ball the distance apart from a r, twizzle and GF yarns group cross central line of longitudinal centre line b<R, r are the radius of GF yarns group.

Wherein, connected by thrust ball bearing between movable bearing support and fixed platform.

Beneficial effect：One kind of the present utility model passively puts yarn mechanism without additional twist, using the structure of passive unwrapping wire Mode, overall structure are simply effective, ensure that, and Can be prevented effectively from during putting yarn and produce additional twist, be conducive to melt to infiltrate.

Description of the drawings

Fig. 1 is this utility model structural representation；

Overlooking the structure diagrams of the Fig. 2 for Fig. 1.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is further described.

One kind as shown in Figure 1 and Figure 2 passively puts yarn mechanism without additional twist, including fixed platform 3 and is disposed thereon The movable bearing support 1 of side, movable bearing support 1 are used for placing GF yarns group；Also include being arranged on the twizzle 4 that GF yarns roll into a ball side, GF yarns group It is highly h, twizzle is arranged on GF yarns group h/2 and highly locates.Movable bearing support 1 includes attic base and is located therein the hollow axle in portion, GF yarns group is on hollow axle and can rotate by axle of hollow axle.Twizzle 4 is arranged at GF intermediate altitudes, and twizzle 4 With GF yarns roll into a ball longitudinal centre line apart from a r, twizzle and GF yarns roll into a ball cross central line apart from b<R, r are the half of GF yarns group Footpath, is connected by thrust ball bearing 2 between movable bearing support 1 and fixed platform 3, and hold-down support can be arranged on fixed frame 5 On.

One kind of the present utility model passively puts yarn mechanism without additional twist, using the frame mode of passive unwrapping wire, overall Simple structure is effective, ensure that, and can be effective Additional twist is produced during avoiding putting yarn, is conducive to melt to infiltrate.

The above is only preferred implementation of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
