Abstract

Needing machine pricker, including needle body, the needle body side is equipped with pinhock, it is characterized by: the needle body includes bar portion and needle tip, the pinhock is distributed in needle tip, there is an articulated base along the setting of needle body needle tip direction in pinhock root, and correspond to pinhock on needle body and be provided with hidden needle tray；The pinhock root is compared with pinhock tip thickness, and pinhock tip is bent to hidden needle tray direction.Pinhock is set to needle body needle point position by the utility model, cloth body surface face will not be damaged when penetrating cloth body, and pinhock is unfolded when pricker exits cloth body by the better obvolvent of fibre web and bonding inside cloth body, to reach non-woven fabrics i.e. good forming effect, internal fibre web obvolvent and the high purpose of degree of adhesion.Certainly it because of the setting of its pinhock, so that the pricker service life is long, is not easy when being pierced into cloth body because the resistance of pinhock makes needle body bend.

Description

Needing machine pricker

Technical field

The utility model relates to prickers, and in particular to needing machine pricker.

Background technique

Needing machine is to pierce, be made into setting at blanket for refractory fiber blanket certain thickness refractory fiber blanket base through compacting, needle It is standby.The principle of needing machine is mainly by pricker, after pricker reaches certain depth, pricker bottom out, forward due to acicular hook Reason, the fiber for generating displacement are detached from acicular hook and are stayed in fibre web with state of almost hanging down, like many fibre bundles " pin " are followed closely Fibre web is entered, to prevent the compression of fibre web generation from restoring, if through tens of or up to a hundred times on fibre web every square centimeter Puncture repeatedly, a great deal of fibre bundle has just been pierced into fibre web, the frictional force in fibre web between fiber and fiber increases, fibre web Intensity increases, increase in density, and fibre web forms the nonwovens with performances such as certain strength, density, elasticity.

But using the needle point structure of cone, the needle body is thinner, such as increases acicular hook on needle block, is piercing for existing pricker end It when entering non-woven fabrics table body, easily occurs bending and deformation, and the resistance being subject to is also larger, needs replacing pricker, and if without acicular hook Setting, for pricker to the dynamic deficiency of the fibre web hook of composition cloth body, non-woven fabrics molding effect is poor, cannot meet production requirement.

Summary of the invention

The purpose of this utility model is exactly the above-mentioned deficiency in order to solve existing needing machine pricker, and providing one kind makes Long with the service life, pricker needle pierces the needing machine pricker for making non-woven fabrics good forming effect.

The technical solution of the utility model problem of being solved is as follows:

Needing machine pricker, including needle body, the needle body side are equipped with pinhock, it is characterised in that: the needle body includes bar Portion and needle tip, the pinhock are distributed in needle tip, have a hinge along the setting of needle body needle tip direction in pinhock root Pedestal is connect, and corresponds to pinhock on needle body and is provided with hidden needle tray；The pinhock root compared with pinhock tip thickness, and pinhock tip to Hidden needle tray direction bending.

Conventional pinhock is additionally provided in needle body bar portion outer surface, and routine pinhock pinhock be distributed compared with needle tip is thin； The pinhock tip Yu bar portion surface of set pinhock maintain an equal level between the needle tip and bar portion.

The pinhock tip of the pinhock of the needle tip is equipped with jag and forms combing prong.

The beneficial effects of the utility model are as follows:

Pinhock is set to needle body needle point position by the utility model, will not be caused brokenly to cloth body surface face when penetrating cloth body It is bad, and pinhock is unfolded when pricker exits cloth body by the better obvolvent of fibre web and bonding inside cloth body, to reach non-woven fabrics i.e. Good forming effect, internal fibre web obvolvent and the high purpose of degree of adhesion.Certainly because of the setting of its pinhock, so that the pricker service life is long, no Easily when being pierced into cloth body because the resistance of pinhock makes needle body bend.

Detailed description of the invention:

Fig. 1 is the schematic diagram of the section structure of the utility model；

Fig. 2 is the schematic diagram of the section structure of Fig. 1 needle body when retracting.

Specific embodiment

Further details of elaboration is made to the utility model with reference to the accompanying drawing.

Refering to fig. 1, Fig. 2, needing machine pricker, including needle body, the needle body side are equipped with pinhock, and the needle body includes bar Portion 1 and needle tip 2, the pinhock 3 are distributed in needle tip 2, have one in 3 root of pinhock and set along 2 direction of needle body needle tip The articulated base 4 set, and correspond to pinhock 3 on needle body and be provided with hidden needle tray 5；3 root of pinhock compared with sharp 6 thickness of pinhock, And pinhock tip 6 is bent to hidden 5 direction of needle tray.

The realization principle of the utility model is as follows:

Needle body is on needing machine in use, needle body is met to the piercing of cloth body, at this point, because articulated base 4 is along needle body needle point 2 direction of portion, pinhock 3 are pierced into needle body, and pinhock 3 is rotated to hidden needle tray 5, make the outside of needle body relative to the drag reduction of cloth body To most weak, so needle body can be very steady and be quickly pierced into cloth body, and excessive destruction will not be caused to cloth body surface face, and In needle body rollback cloth outputting body, pinhock 3 under articulated base 4 and pinhock gravity itself, naturally outward spread at fall Hook, while needle body retracts, fibre web is close to needle body inside cloth body and makes the mutual obvolvent of fiber for forming fibre web along pinhock.

Further, with continued reference to Fig. 2, as the improvement of embodiment, routine is additionally provided in 1 outer surface of needle body bar portion Pinhock 7, the routine pinhock 7 are thin compared with the be distributed pinhock 3 of needle tip 2；The needle of set pinhock 8 between the needle tip 2 and bar portion 1 Bill portion 9 and 1 surface of bar portion maintain an equal level.

Herein, it is noted that pinhock tip shown in Fig. 29 has exceeded 1 surface of bar portion, and Fig. 2 only illustrates, practical in reality During applying, pinhock tip 9 and 1 surface of bar portion maintain an equal level.It, would not be by the fibre inside cloth body in this way in needle body rollback cloth outputting body Mesh belt cloth outputting body surface face.

Further, as the improvement of embodiment, the pinhock tip 6 of the pinhock 3 of the needle tip 2 is equipped with jag and forms comb Reason prong (figure is not marked).

In the present invention, the set combing prong in pinhock tip 6 (figure is not marked) can make to form fibre web when hook moves fibre web Fiber filament can be combed on direction, that is, be oriented to, make fibre web obvolvent inside cloth body and bonding so uniformly, unanimously, Promote the body formed effect of cloth.
