Abstract
The utility model discloses a felting needle of a needle machine. The felting needle comprises a needle handle with an elbow and a needle body, the needle handle and the needle body are detachably connected, a spring device is arranged at the connecting position of the needle handle and the needle body, the needle body comprises a needle rod, a needle blade and a needle point, a forward stabbing hook and a backward stabbing hook are arranged on the needle blade, an arc-shaped protrusion is arranged between the forward stabbing hook and the backward stabbing hook, the felting needle continuously achieves the function of hooking, stabbing, fixing and combining when stabbing and retreating from a fiber web, and the needling efficiency is greatly improved. Meanwhile, the needle body and the needle handle of the felting needle are detachably connected, the felting needle can be independently replaced when damaged, production cost is lowered, the spring device is arranged at the connecting position of the needle body and the needle handle, needle breaking frequency is reduced, and the service life of the felting needle is prolonged. The felting needle is strong in breakage resisting capacity and high in needling efficiency, reduces energy consumption, and is convenient to operate and high in economic benefit.
Description
Technical field
The utility model relates to needing machine field, relates in particular to a kind of pricker of needing machine.
Background technology
Light GMT sheet material is a kind of thermoplastic glass fiber reinforced composite polypropylene board, it is a kind of advanced composite material (ACM) being composited by continuous Glass Fiber Mat and thermoplastic resin, have intensity high, impact flexibility is high, and load is good, high temperature resistant, quality is light, and reproducible utilization is not yielding, the good advantage such as sound-absorbing and sound insulation, odorlessness, is widely used in the fields such as traffic, building, aviation.The preparation technology of light GMT sheet material is a lot, wherein, and can be by the mechanical mixture of glass fibre and improved polypropylene, carding, form through acupuncture hot pressing again.This is the production technology that a kind of properties of product are better, production cost is lower, and wherein carrying out pinprick reinforcement with needing machine has very large impact to the properties of product of finally making.
Pricker is the most important part of needing machine, and its specification and quality have direct impact to the Performance and quality of needling process.The pricker using on needing machine at present, the cross section of its needle is triangular in shape, rhombus or star, on every rib of needle, have the acicular hook in order to hook thorn consolidation fibre that opening direction points to needle point, this type of pricker only plays hook to fibre web and stings fixed effect in the time that pricker thrusts fibre web, pricker release when fiber the hangnail on pricker to fibre web without consolidation, needing machine operating efficiency is lower, and traditional pricker is in use easily subject to larger impulsive force, cause broken needle, in addition after broken needle, just need to change whole pricker, waste lot of materials, increase use cost.
Utility model content
The purpose of this utility model is to provide that a kind of anti-break capability is strong, feed increcement is high, energy efficient, the pricker that easy to operate, economic benefit is high.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of pricker of needing machine, comprise needle handle and needle body with elbow, described needle handle and needle body removably connect, junction is provided with spring assembly, described needle body comprises shank, needle and needle point, needle is provided with forward acicular hook and reverse acicular hook, between forward acicular hook and reverse acicular hook, is provided with arc convex, and described needle point is bulb shape.
Described acicular hook is made up of two spill cambered surfaces, and spill cambered surface is parabolic type.
Described forward acicular hook and oppositely acicular hook are disposed on each rib of needle.
Described forward acicular hook and the oppositely distance between acicular hook are 3-5mm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The needle of the utility model pricker is provided with staggered forward acicular hook and direction acicular hook, make pricker in the time stabbing and exit fibre web, play continuously hook and sting fixed effect, between forward acicular hook and reverse acicular hook, be provided with arc convex, avoid forward thorn to be hooked in being subject to while exiting fibre web reverse acicular hook interference with fiber, this is improved significantly feed increcement, energy efficient, increases economic efficiency.Meanwhile, needle body and the needle handle of pricker removably connect, and pricker can be changed separately in the time damaging, reduce production costs, and junction is provided with spring assembly, can make acicular hook in the time penetrating fiber web, increase cushioning effect, avoid being subject to larger impulsive force and cause too much broken needle in acupuncture course, thereby extend the service life of pricker, and can make pricker remain on tension position, improve pricker and interfibrous entanglement power, make fibre matting more firm, greatly increase work efficiency.
Accompanying drawing explanation
Fig. 1 is pricker overall structure schematic diagram of the present utility model;
Fig. 2 is the enlarged drawing of acicular hook of the present utility model.
The specific embodiment
Below in conjunction with embodiment, the utility model will be further described.
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of pricker of needing machine, comprise needle handle 1 and needle body 2 with elbow, described needle handle 1 removably connects with needle body 2, junction is provided with spring assembly 3, thorn is hooked in while penetrating fiber web, increase cushioning effect, avoid being subject to larger impulsive force and cause too much broken needle in acupuncture course, thereby extend the service life of pricker, described needle body 2 comprises shank 4, needle 5 and needle point 6, needle 5 is provided with forward acicular hook 7 and reverse acicular hook 8, forward acicular hook 7 and oppositely acicular hook 8 are disposed on each rib of needle, forward acicular hook 7 and the oppositely distance between acicular hook 8 are 4mm, between forward acicular hook 7 and reverse acicular hook 8, be provided with arc convex 9, acicular hook is all made up of two spill cambered surfaces 10, spill cambered surface is parabolic type, needle point is bulb shape.Pricker plays continuously hook and stings fixed effect in the time stabbing and exit fibre web, arc convex between forward acicular hook and oppositely acicular hook, avoid forward thorn to be hooked in being subject to while exiting fibre web reverse acicular hook interference with fiber, this is improved significantly feed increcement, energy efficient, increases economic efficiency.
