Description
Technical field
The present invention relates to a kind of warp knitting machine, comprise at least one looping tool strickle, it has a plurality of circle formings and is connected with fulcrum by the guiding pressure pin.
Background technology
For example by the known this warp knitting machine of DE102004023802B3.
Be meant here that as circle forming all can participate in the element of knitted fabric knitting cycle, especially crochet hook, compound needle, guide or sley bar pin, die etc.
Warp knitting machine can have many meters working width.Even working width is big, each circle forming should be able to be parallel to still that width is tighter thickly to adjoin arrangement.In order to guarantee to work in order, different circle formings is cooperating more exactly.For example the sley bar pin must be able to pass space swing between pin between the crochet hook, does not clash with crochet hook.For fiber number E24, wherein for example per inch is established 24 crochet hooks, only is slightly larger than 1 millimeter for every crochet hook and adjacent with it space provide.
When warp knitting machine is worked, because various influences are in machine run-stopping status and formation temperature difference between the production phase.This temperature contrast at first causes by the discharging of the different heat energy of machine itself, but also is subjected to external action, for example in the variations in temperature of machine place environment or direct solar radiation.
Temperature change causes length variations for most of elements of warp knitting machine because of thermal expansion.This situation especially betides looping tool strickle, but also betides the other machines element.Especially in the warp knitting machine of operation very apace, can cause the needle gage problem easily thus, thus may be until causing circle forming to clash.Even without conflict, different thermal expansions also can cause negative influence to the knitted fabric quality of producing.
As everyone knows, the spindle case of warp knitting machine is heated to a temperature at run-stopping status, and the normal temperature during it and the production run is corresponding.Heating is often undertaken by heater, and it passes to machine casing, connecting axle and looping tool strickle by oiling in machine casing equably with predetermined temperature.
When high machine speed, can produce overtemperature during work, adopt cooler for it is got rid of by friction and so on.Cooler remains on oily temperature the level of a regulation.By this register that not only can heat but also can cool off, can reduce the thermal expansion or the contraction of looping tool strickle, and thereby to the positive influence of needle gage precision generation.
The another kind of possibility that solves the problem that is associated with thermal expansion is that looping tool strickle is made by fibre reinforced plastics.It is less sensitive that this plastics sley bar causes that for temperature change material expands.But because these sley bars are fixed on the metal fulcrum, so the thermal expansion of fulcrum still may cause the looping tool strickle distortion.Because the looping tool strickle of plastics absorbs heat hardly, in addition play a part heat insulation, so also there is heat to pass to sley bar and not entering the surrounding environment therefrom by the guiding pressure pin from fulcrum.Consequently, in some cases production period in the guiding pressure pin and thereby on fulcrum, form to a certain degree accumulation of heat, this causes fulcrum thermal expansion more seriously, from and the shape of looping tool strickle caused negative effect.Described situation also causes the position of circle forming to move relative to each other.
Therefore in the DE102004023802B3 that preface is mentioned, advise that fulcrum is also made with fibre reinforced plastics.Yet this scheme is very uneconomical.Especially this scheme cost is very high, because the pressure pin that leads in addition except fulcrum is also made with fibre reinforced plastics.
Summary of the invention
The purpose of this invention is to provide a kind of warp knitting machine, it is less sensitive to temperature effect in simple in structure.
For reaching this purpose, the measure of taking in the warp knitting machine of the described type of a kind of preface is that fulcrum is divided into a plurality of sections and each section separate support vertically.
Adopt this programme only to cause thermal expansion all the time at section of fulcrum of limited length.Because thermal expansion generally with temperature change and proportional with the length of expander, so, make because the temperature contrast length that can expand is little by fulcrum being divided into some axial section.Therefore, although circle forming can not be got rid of fully based on moving of temperature change, this mobile amount can reduce.
Also advantageously, warp knitting machine has a frame, and each section separate support is in frame.
Therefore fulcrum can support highly stablely, thereby allows the high speed of service.
Preferably, frame has a plurality of support plates, and each section is bearing in two support plates at least.Usually frame has two end walls and an a plurality of support plate that is located between them distolateral.No matter support plate still is an end wall all is called " support plate " here, because their function mainly is fulcrum is fixed as, fulcrum can be rotated, in order that make looping tool strickle can implement oscillating motion.If each section is bearing in two support plates at least, all sections that then can reach fulcrum always keep coaxial, thus make looping tool strickle oscillating motion can with one along its total axial length by one section fulcrum that constitutes compare in fact do not have different.
Preferably, adjacent sections has spacing when temperature is 20 ℃.This distance that also can be described as " expansion clearance " should be defined as, even make it also can be closed under the temperature that warp knitting machine production or run duration produce.Avoid the expansion of a section to be subjected to the obstruction of adjacent sections thus.Therefore in fact the section of fulcrum can keep the axial stress that do not have heat to cause.
In this respect preferably, spacing is located at an intralamellar part.That is to say and can't see spacing from the outside.Therefore only there is the danger in the spacing between the very little exotic intrusion adjacent sections.Exactly, described spacing or expansion clearance are subjected to support plate protection, thereby keep the expansion possibility of each section in long-time.
Preferably, first section is located near the jacquard weave transmission device and has one to face the fixing vertically end of jacquard weave transmission device.Otherwise for the axial restraint of all the other sections, they are connected to each other by looping tool strickle and guiding pressure pin.Because first section is fixing vertically, so fulcrum axial restraint on the whole, meanwhile each section can expand, and looping tool strickle is not had negative effect.
Preferably, looping tool strickle is connected with a section by a guiding pressure pin respectively.Exclude the possibility thus, the thermal expansion meeting of a section causes the distance of adjacent guiding pressure pin to change, and this variable in distance can cause the looping tool strickle distortion again.It undoubtedly is enough that looping tool strickle is fixed on the section by a guiding pressure pin.
In this respect preferably, the guiding pressure pin is contained in the section central area vertically.Therefore described section expands at guiding pressure pin two ends vertically when temperature change or shrinks, and the shape of looping tool strickle is not had negative effect.
Preferably, looping tool strickle has a kind of fibre reinforced plastics as main component.The expansion that fibre reinforced plastics assurance looping tool strickle both be not worth mentioning when temperature change is not shunk yet.Because otherwise each section of fulcrum can expand or shrink, so even use fibre reinforced plastics temperature difference still to obtain very high needle gage precision, those shortcomings of seeing so far can not appear in the plastics sley bar.
Preferably, the guiding pressure pin is made of aluminum or aluminum alloy.Aluminium, for example cast aluminium, or aluminium alloy are a kind of reliable and economic materials.Aluminum or aluminum alloy has the sufficiently high capacity of heat transmission, so the high temperature that produces on fulcrum or its section can be by the pressure pin environmental emission towards periphery that leads.Reach certain balance thus, make the section of fulcrum can not be heated to the temperature that surpasses regulation.
Additionally can also establish register by a favourable design.This register can for example influence the oil temperature in the frame.The temperature that can keep frame thus equably is not although propose so high requirement to the uniformity as so far.
Description of drawings
By preferred embodiment the present invention is described below in conjunction with accompanying drawing.Wherein:
The partial front elevation view of Fig. 1 warp knitting machine signal; And
The local fragmentary cross-sectional view that amplifies of Fig. 2.
The specific embodiment
Fig. 1 very schematically represents warp knitting machine 1, and it comprises a frame 2 that a plurality of support plate 3-6 are arranged.Here, support plate 3,6 constitutes distolateral end wall, and support plate 4,5 constitutes intermediate plate.Establish a jacquard weave transmission device 7 that only schematically illustrates at an end of frame.
The looping tool strickle 8 that for example has sley point, crochet hook, compound needle or other circle forming is fixed on the fulcrum 10 by guiding pressure pin 9.If fulcrum 10 rotations (establishing the driver of not representing among the figure) for this reason, pressure pin 9 revolutions of then leading also make looping tool strickle 8 move by a kind of mode of oscillating traverse motion thus.If looping tool strickle 8 for example is designed to sley bar, sley point passes space guiding between pin between the crochet hook when described oscillating traverse motion.The pressure pin 9 that leads for this purpose is permanently connected with fulcrum 10 rotations.Looping tool strickle 8 is made by fibre reinforced plastics basically, and in fact its expansion does not have or have only relation seldom with temperature.
Between adjacent section 11-13, be respectively equipped with one and be the spacing 14,15 of expansion clearance in form.For for example a size being arranged 20 ℃ the time, this is sized to spacing 14 in normal environment temperature, and the thermal expansion that makes adjacent sections 11,12 produce under operating temperature can not cause adjacent sections 11,12 to contact.Therefore, each section 11-13 in fact unhinderedly expands, and can not contact mutually.
As seen from Figure 2, each section 11-13 is bearing in two support plates 5,6.Spacing 14 is in the middle of the support plate 5, so it is capped around.Basically can prevent in the exotic intrusion spacing 14.
Section 11 is bearing in the support plate 5,6 by roller bearing 16,17.Fig. 2 does not represent the fixing of pressure pin 9 that lead.Guiding pressure pin 9 is fixed on the central authorities of section 11-13 separately substantially.If section 11-13 rises based on temperature and expands, then this expansion can be carried out at two ends substantially symmetrically from each pressure pin 9 of leading, so guiding pressure pin 9 is in fact constant with respect to the position of looping tool strickle 8.
Be located near jacquard weave transmission device 7 first sections 11 and only illustrate that by one the fixture 18 on the face of land is fixing vertically with respect to frame 2.Described fixing can enforcement at that end that faces the jacquard weave transmission device.Fix and also can carry out in the end opposite of first section 11 or in other position.Therefore also can fix other sections 12,13 vertically by looping tool strickle 8 and guiding pressure pin 9, obviously allow thermal expansion here, can not cause looping tool strickle 8 distortion or be subjected to mechanical stress with respect to frame 2.
Guiding pressure pin 9 usefulness aluminum or aluminum alloy are made.The section 11-13 of fulcrum 10 can make with steel.Therefore the heat that produces at work can discharge to a certain extent by guiding pressure pin 9 and give surrounding environment.Frame 2 also can have a register by the mode that does not have further expression, and the oil that will exist in frame 2 by it remains constant temperature.
