Description

Speed change gear box device for multi-speed adjustable controllable cloth-rolling machine

The present invention provides a kind of structure relevant for the batcher change gear box, be meant especially a kind of can be easy the cloth cylinder is made the change gear box device of speed change regulation and control, with average cloth elasticity, and its gears engaged is easy to adjust, make the simple and easy smooth operation of transformation of speed work, compile frame in circle simultaneously and weave cloth unusual (slowly) when influencing granny rag, energy is granny rag slowly, avoid causing the rapid accumulation (floating cloth) of weaving cotton cloth and make the knitting needle fracture, and the sound that gives a warning is fixed a breakdown with the prompting staff.

General circle is compiled the cloth that frame is weaved and finished, they must be via the according to need and suitably tension and compression of bolt machine, make it to become the yardage roll of different degree of tightness density and code weight, so the rotating speed of this batcher granny rag and strength degree of stability have direct critical impact for the quality of yardage roll quality of finished, therefore, how general batcher can suitably be adjusted the velocity of rotation of its granny rag cylinder, to draw the yardage roll that rolls out required different densities for can cooperate cloth material difference and tightness difference.

Yet, more traditional in present batcher change-speed gearing box structure, have with the continuously variable transmission device of belt and belt pulley transmission and change the travelling gear mode of the different numbers of teeth, reach the purpose of conversion rotating speed; But owing to the batching power that transmits heavy load with belt, often there is the phenomenon of skidding to produce, causes the cloth rolling to have the situation of density unevenness, have a strong impact on the quality of yardage roll, and because of the elasticity inequality of cloth, make the abrasion of knitting needle serious, have a strong impact on its service life; And, then can obtain preferable transmission of power effect to change the mode of meshing gear, but change the very complicated inconvenience of different travelling gear operations at every turn, need can proofread and correct to required rotating speed through repeatedly replacing, form the obstacle in the batching production procedure.

Progressive, though some effect of gear box device, but for day by day accurate knitting machine structure, no matter weave cotton cloth style, the number of plies, density etc., the capital influence is the speed of cloth down, with less speed change, the deceleration effect of this device segmentation, has been difficult to satisfy modern complicated the cloth style or the substantive requirements of form, and its gear-box is eccentric configuration with the configuration of rotation fulcrum, easily produces the shortcoming of the right and left granny rag uneven phenomenon because of eccentric rotary.

And this gear-box, another stepped gear group of transmission front side after the stepped gear group on the left of its structure is driven by final drive shaft in this way, the travelling gear on the scalable pivot drive right side of gear train is taken in the front side, and the travelling gear that makes the right side revolved the selection that control handwheel and rack pull bar thereof are made the total number of teeth in engagement ratio, produces different deceleration rotating ratios with the right side stepped gear group of engagement.Yet, four groups of stepped gear complex structures of this change gear box, during gears engaged speed change proportioning, every coarse adjustment section speed can't set out the average speed ratio, during adjacent coarse adjustment section speed speed change, before its single coarse adjustment section speed gear train, after the fine setting hop count, fine setting hop count with adjacent front and back two coarse adjustment hop count gear trains, produce multistage fine setting hop count and repeat, so that operate shifted back and find that two adjacent coarse adjustment hop counts are not to liken continuous change to average speed, serious often just realizes the cloth code weight that weaves after cloth weaving one big section, bar is apart from also non-required, so that to consume cloth extremely many, and its driving gearshaft is again extension type, when reality is used, more be difficult to accurately control gear ratio, and the driving gearshaft torsion strength of retractility is not enough, takes place easily that tooth collapses or other faults, also has the dismounting maintenance to be difficult for, shortcoming such as with high costs.

And to finish the effect of automatic conversion rotating speed with aforementioned gear box structure, its arrangement of clutch is indispensable composition important document, common clutch teeth wheels and the conversion of stepped gear group from, close the dependency structure of state, as shown in Figure 1, wherein gear-box 91 internally-powereds are passed to the clutch teeth wheels via driving shaft 911, these clutch teeth wheels are fixed on the pivotable guide pillar 912, gear-box 91 central authorities are provided with a stepped gear group 92 in addition, this stepped gear group 92 also stretches out with a granny rag line shaft 913, gear-box 91 tops are hubbed at an end of a clutch slide plate 93 with a pivot 931, these clutch slide plate 93 stage casings are provided with a slotted hole 932, can drive an eccentric wheel 94 for a driving lever 941 pivots in it, another of clutch slide plate 93 is distolateral to be provided with an inclined guide groove 915 to the oblique extension of central authorities, and this inclined guide groove 915 just can be nested with the top side of aforementioned guide pillar 912.

During variable speed operation, make gear-box 91 stop action fully earlier, pulling driving lever 941 rotates counterclockwise clutch slide plate 93, can make guide pillar 912 tops driven by the inclined guide groove 915 of clutch slide plate 93 and pivot, the clutch teeth wheels then break away from the state that meshes with stepped gear group 92 simultaneously, adjust the clutch teeth wheels again to another predeterminated position (guide pillar 912 tops also slide on another location in the inclined guide groove 915) thereupon, pulling driving lever 941 homings, guide pillar 912 is pivoted and the clutch teeth wheels are also replied and the state of stepped gear group 92 engagements (but with different gears engaged), so can reach the effect of conversion transmission rotating speed.

Yet, though it can reach the effect of simplifying the gear-box variable speed operation said structure, but because this clutch slide plate 93 itself is pivotally to slide, inclined guide groove 915 is oblique extension in addition, cause the clutch teeth wheels that pind down by guide pillar 912 to change with the adjustment work of stepped gear group 92 positions of engagement very difficult, often need angle correction repeatedly, can correctly be meshed, cause the inconvenience in the application.

Moreover, because being in long-term the volume fast, circle volume frame spins action, it causes out the unusual situation of cloth to take place unavoidably because of needle wear or other fault, and easily form the unusual pulling force of batcher when slow when going out cloth, for the effect of avoiding aforementioned unusual pulling force causes the more serious damage of other device, the relevant structure that prevents generally all can be arranged, and the more common structure that prevents unusual pulling force batching, as shown in Figure 2, it is with granny rag line shaft 913 outputting powers, granny rag line shaft 913 is then via the interlock axle sleeve 9141 of an interlock axle sleeve 9131 in abutting connection with a granny rag power transmission shaft 914, and this

interlock axle sleeve

9131,9141 then are connected polyphone with safety pin 916, rotate by a plurality of granny rag cylinders on these granny rag power transmission shaft 914 driving rotational framves, to finish the action of granny rag and batching; And if aforementioned circle volume frame goes out the phenomenon that cloth slowly has some setbacks in the braiding process, then the granny rag cylinder can't smooth and easy granny rag, and produce great active force in granny rag power transmission shaft 914, make 914 of this granny rag line shaft 913 and granny rag power transmission shafts great twisting force be arranged in safety pin 916, when this torsion is excessive then be enough to destroy safety pin 916 make it the fracture, this granny rag line shaft 913 then, the torsion transmission that the granny rag power transmission shaft is 914 is also interrupted thereupon, avoided going out cloth unusual (slowly) thus and made still lasting batching in circle volume frame, cause yardage roll to form the bad situation of quality that density is dredged excessively because of excessive pulling force, but this moment is because former volume frame still is in the continuation woven condition, its longitude and latitude knitting needle is not drop-down because of preceding cloth, produce when causing back stitching and knit line (being commonly called as the striker phenomenon), may cause the hundreds of Zhi Zhizhen fractures of whole dish at last, form loss greatly.

Again, have as shown in Figure 3, it is a kind of " safety of batcher speed change gear disconnected can structure ", it mainly is to disclose a cone clutch 95 to locate swivel nut 961 with what Outer Taper 952 installings one and granny rag power transmission shaft 914 were connected interlock mutually from multi-stage gear 96 and, and can adjust swivel nut 971 and a bearing 972 and a compression spring 97 by one, adjust pushing away of 951 of cone clutch 95 Outer Taper 952 and inner cones and pull out friction, when power then is passed to disconnected energy member from multi-stage gear 96, by cone clutch 95 power is exported by granny rag cylinder 82, friction is pulled out in pushing away of 951 of the Outer Taper 952 of cone clutch 95 and inner cones, then can be by adjusting swivel nut 971 and compression spring 972 its sizes of control.

Therefore, when batcher running takes place unusual and is stuck, and reversing frame 8 is when being rotated further, power tosses about in bed to reach this disconnected energy member, and when the resistance of granny rag cylinder 82, when providing pushing away of cone clutch 95 to pull out friction by compression spring 97,951 of the Outer Taper 952 of cone clutch 95 and inner cones just have the relative motion generation, and will consume by the kinetic energy that transmits by its dyanainic friction power, therefore can not cause transmission device moment damage.

Yet, though it can compile above-mentioned various structure frame in circle and go out cloth and stop batcher granny rag cylinder 82 when unusual and rotate, cause the bad and gear-box damage of the thin excessively quality of batching with improper pulling force and the reaction force of avoiding continuing the constant speed granny rag, but situation and reason that in fact round volume frame breaks down in the braiding process are extremely many, and it goes out that cloth has some setbacks or stuck phenomenon also is not quite similar as described above, if only stop the batching action separately, and original fault is not got rid of, then circle volume frame still might continue to weave bad cloth and continue cloth, this moment, bad cloth pushed away long-pending (promptly generally being commonly called as " floating cloth ") in granny rag cylinder 82 tops, the situation that causes circle to compile the fracture of frame knitting needle easily produces, and forms loss greatly.

Purpose of the present invention aims to provide a kind of tool safety bearing pin Multi Rotational Speed Control formula batcher change gear box device.

The object of the present invention is achieved like this, and it is arranged with coarse adjustment gear train, fine setting gear train, stepped gear group, clutch transmission group and many group power transmission shafts etc. partly in gear-box; When transmission of power during to the batching power transmission shaft, be articulated in the coarse adjustment gear of batching power transmission shaft, the fine setting gear train is driven by travelling gear respectively, and the gear of the different gear ratios of engagement that elect, power is tossed about in bed to transfer to the clutch transmission group, control arbitrary gear of its engagement stepped gear group by a clutch slide plate, reach transmission power and select to do and increase, the deceleration conversion, required drive is transferred to the granny rag turning cylinder through a safety pin device, formation is applicable to that the round needle loom makes the multiple speed change of conversion, make cloth code weight bar apart from reaching stable and consistent, and tool prevents out the structure of the unusual tension of cloth, and this is a main purpose of the present invention.
