Description

A kind of hollow needle bed of tricot machine

Technical field

The utility model is related to tricot machine field, specific field is a kind of hollow needle bed of tricot machine.

Background technology

The needle bed generally use almag proximate matter of tricot machine, then processes several needles with milling machine by the spacing of setting Slot can theoretically improve its rotating speed, in the actual use process, aluminium although almag is lighter than general metal Magnesium alloy is easily deformed, and coefficient of thermal expansion is higher, is expanded with heat and contract with cold obvious, is affected by environment temperature, this is instead not Its complete machine rotating speed can be improved, on and its stability also influenced, be easy to cause situations such as having an injection, greatly reduce woven fabric matter Amount.

A kind of the warp knitting machine needle bed of running at normal temperature is disclosed in the application documents of Patent No. ZL200820040684.8, Needle bed matrix is carbon fiber needle bed matrix in this document, and although carbon fiber is unlikely to deform, but expensive, in addition in this document Needle bed matrix be solid structure, the needle bed matrix of solid construction is heavier and rigidity is defeated by the needle bed base of hollow-core construction with intensity Body.

Utility model content

The purpose of this utility model is to provide a kind of hollow needle beds of tricot machine, to solve needle bed cost in the prior art The problem of high and heavier-weight.

To achieve the above object, the utility model provides the following technical solutions：A kind of tricot machine hollow needle bed, including needle Bed matrix and needle tray body, the needle bed matrix are hollow-core construction, and the needle bed matrix is assorted fibre needle bed matrix, the needle tray Body is nonmetallic groove body, and needle tray body end face is equipped with multiple spaced needle trays, and needle is pasted or be embedded in the needle tray body The upper end of bed matrix.

Preferably, the assorted fibre is made of carbon fiber bundle and glass fiber bundle of the two-way weaving of plane, warp Upward carbon fiber bundle is arranged with glass fiber bundle interval, and the carbon fiber bundle in broadwise is arranged with glass fiber bundle interval.

Preferably, the needle bed matrix is made of 20-40 layers of assorted fibre lamination laying.

Preferably, the needle tray body is made of the long polyester item of polyimides.

Preferably, it is respectively upper hollow hole and lower hollow hole, the overhead to be set on the needle bed matrix there are two hollow hole The shape in heart hole is similar to needle bed matrix cross sectional shape, and the lower hollow hole is quadrilateral structure and upper and lower two sides are mutually flat Row.

Compared with prior art, the utility model has the beneficial effects that：A kind of tricot machine hollow needle provided by the present application Bed, needle bed matrix is made of assorted fibre, light-weight and cheap, and hollow-core construction can also improve the whole rigid of needle bed matrix Degree and intensity can greatly reduce the deflection of needle bed under same operating condition, ensure that needle gage is stablized, needle bed is made to run More stablize steadily in journey, the running speed of complete machine can be greatly improved, improves production efficiency.

Description of the drawings

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

Fig. 2 is the braiding structure schematic diagram of assorted fibre in the utility model.

In figure：1 needle bed matrix, 2 needle tray bodies, hollow hole, 4 times hollow holes, 5 carbon fiber bundles, 6 glass fiber bundles on 3.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of hollow needle bed of tricot machine, including needle bed base Body 1 and needle tray body 2, needle bed matrix 1 are hollow-core construction, and needle bed matrix 1 is assorted fibre needle bed matrix 1, and needle tray body 2 is nonmetallic Groove body, in the present embodiment, needle tray body 2 are made of the long polyester item of acid imide, and 2 end face of needle tray body is equipped with multiple spaced needles Slot (not shown), the needle tray for installing needle body, needle tray body 2 by way of pasting or inlaying with the upper end of needle bed matrix 1 Portion connects.

Specifically, assorted fibre is made of carbon fiber bundle 5 and glass fiber bundle 6 of the two-way weaving of plane, i.e., just Lattice cloth weaving, as shown in Fig. 2, being arranged through upward carbon fiber bundle 5 and the interval of glass fiber bundle 6, the carbon fiber in broadwise Beam 5 is arranged with the interval of glass fiber bundle 6, and two kinds of fibers, 90 ° of weavings, compared to laminate structures, tensile property is more preferable, compares For common Single Fiber enhancing laminate, assorted fibre more stabilization, the mechanical property of woven roving structure are better.

For the intensity requirement for meeting in needle bed operational process, needle bed matrix 1 is by needle bed matrix 1 by 20-40 layers of assorted fibre Lamination laying is made, specifically, passing through resin-bonding between each layer of assorted fibre.

Further, it is respectively upper hollow hole 3 and lower hollow hole 4 to be set on needle bed matrix 1 there are two hollow hole, in this reality It applies in example, the shape of upper hollow hole 3 is similar to 1 cross sectional shape of needle bed matrix, 3 left end wall thickness 3mm of upper hollow hole, right end upper side wall Thick 4.5mm, downside wall thickness are 3mm, and lower hollow hole 4 be the quadrangle that surrounding is smooth circular arc, parallel below on quadrangle, up and down The parallel rigidity that can make needle bed matrix 1 in side is stronger, and in the present embodiment, 4 left and right ends wall thickness of lower hollow hole is 4mm, bottom end Wall thickness is 8mm, and upper and lower hollow hole 4 is spaced 3mm, and the left and right angle in 1 bottom end of needle bed matrix is respectively 116 °, 43 °.

The hollow needle bed of a kind of tricot machine provided by the present application, because the low-density of assorted fibre, gross mass have dropped 30%, compared with the needle bed of pure carbon fiber, it is mixed with the glass of lower price, cost has dropped 40%, and uses grid The weaving manner of cloth possesses better mechanical property compared to laminate structures, and hollow-core construction can also improve the whole of needle bed matrix Body rigidity and intensity can greatly reduce the deflection of needle bed under same operating condition, ensure that needle gage is stablized, needle bed is made to transport More stablize steadily during row, the running speed of complete machine can be greatly improved, improves production efficiency.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
