Directive wheel support 1 usefulness screw 13 as the needle beam guiding mechanism of needing machine of the present invention is fixed on the default screw 22 in connecting rod base 23 ends, and directive wheel 2 by wheel shaft 12 hub setting on directive wheel support 1.The material of directive wheel 2 can be metal directive wheel, it also can be the directive wheel of nylon system, it can also be the directive wheel of as present embodiment, selecting high abrasion modified MC nylon alloy material for use, the directive wheel of this MC nylon alloy material can widely obtain from market, for example adopts the aluminium alloy MC nylon wheel by the production and sales of east, Chinese Ningbo City, Zhejiang Province electric power facility Manufacturing Co., Ltd.At the entablature base plate 33 fixed guide seats 3 of the outside of directive wheel 2 correspondence position by means of the frame entablature 34 of needing machine, the both available welding of fixed form is fixed, also can or fix with screw or with other similar fashion for riveted joint, particular location is that the back side that is fixed on entablature base plate 33 is on the lower surface.The pair of guide rails 4 that constitutes guide groove 14 is on the lower surface to weld or to be screwed at the back side of track base 3 equally.Here, the applicant it may be noted that: if on track base 3, directly process guide rail 4, should regard it as so will be separately guide rail 4 solid weldings equivalent to the track base 3 of processing.On guide rail 4, be sliding combined with the guide pad slip and adjust seat 5, according to simple mechanical general knowledge, on guide rail 4, constitute guide groove 14 if resemble this example, guide pad slide to adjust that just to process leading of matching with guide groove 14 on the seat 5 prominent so, both constitute sliding joining, otherwise, if guide pad slide to adjust and to process on the seat 5 or claim to be formed with guide groove, just on guide rail 4, be formed with so with guide groove slippery lead prominent.These explanations of applicant are intended to illustrate that guide rail 4 and guide pad slide adjusts both cunnings of seat 5 and join the restriction that is not subjected to the form shown in the accompanying drawing.The both sides that are the guide pad slip adjustment seat 5 of 7 fonts in shape substantially respectively are processed with at least one limiting groove 10, and on limiting groove 10, set dog screw 11, dog screw 11 revolves and on guide rail 4, that is to say that dog screw 11 passes limiting groove 10 and is rotated with on guide rail 4.Guide pad 6 is screwed on guide pad slides adjustment seat 5, the position is corresponding with aforesaid directive wheel 2, cave in and become to have a guiding race 7 in the position placed in the middle of guide pad 6, the length of guiding race 7 should satisfy at least to the connecting rod base 23 required amplitude (also claiming traverse) that moves up and down, and the width of guiding race 7 should satisfy and the corresponding to degree of the thickness of directive wheel 2, and that is to say is enough to make directive wheel 2 to compensate in the guiding race 7.For adjusting seat 8, both can be separately and track base 3 realize fixing, also can be separately and guide rail 4 fixing, for example will adjust seat 8 and be worked into the strip longer than the shape of current icon, its two ends are fixing with guide rail 4 respectively, can also make adjust seat 8 not only with track base 3 but also fixing with guide rail 4, therefore, can not limit the present invention with the concrete fixed position of adjusting seat 8.For regulating part 9, the preferred employing adjusted screw, this adjustment screw both can be directly and the guide pad afterbody of adjusting seat 5 that slides connect firmly, can not connect firmly yet, only contact, preferred technological means is that itself and guide pad slip are adjusted seat 5 connections, because can make guide pad slide adjustment seat 5 along with adjusting the suitable of screw or being rotated counterclockwise and the improvement of position that realizes advancing and retreat like this, present embodiment is selected this kind means.If do not connect firmly and will not adjust screw and guide pad slip adjustment seat 5, though do not influence so and guide pad slide is adjusted seat 5 regulate towards directive wheel 2 one sides, promptly push, but, then can only drive artificially with hand when guide pad being slided adjust seat 5 when deviating from directive wheel 2 adjustings by adjusting screw.Owing to slide to adjust on the seat 5 at guide pad and to be provided with limiting groove 10, so the slide advance and retreat distance of adjusting seat 5 or claim distance slidably to be positioned at the length range of limiting groove 10 of guide pad.
Though above only introduced the needle beam guiding mechanism of the needing machine of one group of structure of the present invention, but can not bring the puzzlement in the understanding to the guiding mechanism of one group of same structure being configured in connecting rod base 23 other ends, because the applicant explains in front, structure of the present invention is made into using.
Still please see accompanying drawing, the applicant sketches the application of needle beam guiding mechanism on needing machine of needing machine of the present invention.Needing machine with double link crosspointer plate is an example, actuating unit by needing machine orders about main shaft 35 rotations of a pair of hub setting on bearing block 15, the pair of links 17 that the upper end is linked in abreast by eccentric wheel 16 on the main shaft 35 is moved, because the lower end of each connecting rod 17 is bound up on the connecting rod base 23 by little axle 30, and by the axle head of the little axle of bearing cap 28 cap seals 30, that is to say that the lower end of connecting rod 17 is stretched over connecting rod chamber 21 interior the realizations and connecting rod base 23 connections of connecting rod base 23, thereby move up and down by the drivening rod seat 23 that moves up and down of connecting rod 17.Because needle beam 25 is connect by screw 24 and connecting rod base 23, therefore along with the moving up and down of connecting rod base 23, needle beam 25 is also corresponding to move up and down.Also because the needle plate 27 that is furnished with pricker 26 by technological requirement fixes with needle beam 25, so needle plate 27 moves up and down, make the entanglement thorn and close and form corresponding on-woven product by the pass through on-woven fiber of its below of 26 pairs of the prickers on the needle plate 27.Enter in the connecting rod chamber 21 of connecting rod base 23 in order to reduce foreign material, also show the dirt-proof boot 20 of being furnished with hairbrush bar 19 in the drawings, this dirt-proof boot 20 also is that the tie rod holes position configuration is aimed at screw 31 fixed-site to the default dirt-proof boot holder 29 in connecting rod base 23 tops and with screw 32 at the dustproof trepanning 18 of entablature base plate 33.
In the motion process of mentioning in the above, rolling pendulum phenomenon can appear in needle beam 25 inevitably, the operating rate of needing machine is high more, the rolling pendulum is serious all the more, therefore, since the two ends of connecting rod base 23 be the current icon location status about end all be provided with the directive wheel support 1 that hub setting that the present invention recommends has directive wheel 2, again owing on entablature base plate 33 and at position, be provided with the guide pad 6 that the present invention recommends corresponding to directive wheel 2, thereby make connecting rod base 23 about rolling pendulum controlled, can only in the range of movement that directive wheel 2, guide pad 6 are limited, move.If after using a period of time, distance between directive wheel 2 and the guide pad 6 is because of certain reason when for example directive wheel 2 suffers that reasonably wearing and tearing change, so as long as turn regulating part 9, make guide pad slide to adjust seat 5 along guide rail 4 towards directive wheel 2 direction slide, contact with guiding race 7 until directive wheel 2, guarantee that guide pad 6 is pasting 7 motions of guiding race.
In sum, structure of the present invention extremely is suitable for the needle beam guiding to the needing machine of non-guide, guide pin bushing, because as long as the rolling pendulum does not appear in connecting rod base 23, needle beam 25 just can not produce the rolling pendulum so, thereby can guarantee acupuncture effect.Especially, need not to rely on oil lubrication, thereby do not have the sorrow of oil seepage for directive wheel 2, guide pad 6; And whole guiding mechanism is compared with for example aforementioned CN2753764Y of prior art, and amount of parts has obtained reasonable minimizing, and is simple in structure, have a good and economic.Through the applicant structural arrangements of the present invention is being tested (in applicant unit and under confidential state) on the needing machine of double link crosspointer plate, after 2400 hours, check, distance between directive wheel 2 and the guide pad 6 keeps as before, and connecting rod base 23 motions are in plateau all the time and do not have the rolling pendulum.Yet, the guiding mechanism of simulating in the CN2753764Y structure is tested under the state of equal-wattage, same size, identical speed, the result just had the oil seepage phenomenon after 300 hours, wearing and tearing appear in tooth bar, gear ring after 1000 hours, and there is slight rolling pendulum in connecting rod base 23.As seen, the needle beam guiding mechanism of needing machine of the present invention can be described as ultimate attainment.
