Abstract
The utility model relates to a yarn-feeding driving device of triangle rotary knitting machine. One cylindrical gear is fixed on the surface of the original knitting machine through a column, and the other gear is connected with the central shaft of the original knitting machine through a rolling bearing. The cylindrical gear revolves with the central shaft, simultaneously, and oppositely revolves with the central shaft, a planetary gear device is formed, so the problem of yarn-feeding driving of the triangle rotary knitting machine can be fundamentally solved. After the planetary gear device is installed, the quantity of yarn-feeding with each route can be accurately controlled, and both the uniform degree of a coil and the surface quality of grey cloth are enhanced. The width, the density and the gram weight of fabric can be well controlled.
Description
The utility model belongs to the hosiery industry field.
The applicant has consulted the data of the domestic and international parties concerned; More domestic knitting mills have been visited; Visited the domestic ITMA of holding; And according to professor expert of knitting industry reflection.The defeated line transmission mechanism that does not also have this type at present both at home and abroad.
The purpose of this utility model is for triangle rotation (being the creel rotation) the fixing knitting machine of syringe provides a kind of active type to fail line transmission mechanism, thereby makes the knitting machine of this type can realize actively defeated line.
Along with the raising of knitting machine braiding speed, the increase of advancing the yarn way, more and more higher to the requirement of defeated line.The wire delivery mechanism of active type has become the important component part of contemporary knitting machine.Common has: strip-type wire delivery mechanism, roller rod formula wire delivery mechanism and comparatively advanced storage yarn formula wire delivery mechanism.But these wire delivery mechanisms just are used in syringe rotation at present on the motionless circular knitting machine of triangle, can't to fix the circular knitting machine of triangle rotation (as the Z101 rib knitting machine etc.) class used for syringe.Owing to can not adopting actively defeated line, existing this type of knitting machine adopt passive type to fail line.Will make the defeated line amount between each road inconsistent like this; The knitting tension fluctuation is bigger; The uniformity of coil and the presentation quality of grey cloth have been influenced; The density of fabric, the door width of cloth and grammes per square metre change greatly.Particularly for rib fabric, be easy to take place the broken yarn phenomenon of press-offing.The knitting needle consumption is big, and labour intensity is big.So we think that this type of knitting machine can adopt actively defeated cotton suittings? is the difficulty of the actively defeated line of employing there? we have analyzed meticulously for this reason.On this type of circular knitting machine of interlock machine, the transfer motion power of active type wire delivery mechanism derives from main shaft.This is that i.e. each own motion of wire delivery mechanism and main shaft all is the absolute movement with respect to ground because the two all is in autorotation.And the knitting machine of triangle rotation is different with them, and the motion of its wire delivery mechanism is a kind of resultant motion, and it also will rotate with creel cast-over tube except self rotates.And the direct transmission wire delivery mechanism of the rotation of main shaft itself.So transfer motion power how to obtain wire delivery mechanism is a key issue.By analysis, we think needs to increase a roller gear (internal tooth or and external gear) 3 that is fixed in table top; As shown in Figure 1, utilize gear 3 and planetary gear 13 relative motions transfer motion power as wire delivery mechanism.Planetary gear 13 revolves round the sun with creel again except relatively rotating with gear 3.The belt pulley 10 coaxial with planetary gear tooth 13, the belt pulley that utilizes punching band 7 to drive wire-delivering units 12 rotates, thereby reaches the purpose of actively defeated line.
The utility model comprises: parts such as column 2, gear 3, dividing sinker dish 4, wire-delivering unit carriage 5, belt tension governor motion 6, transmission band 7, regulating wheel 8, creel 9, belt pulley 10, pulley transmission mechanism 11, wire-delivering unit 12, planetary gear 13, oil baffle 14, central shaft 15.Column 2 is fixed on the table top 1 of former knitting machine, can be with three or four, and gear 3 is fixed on the column 2 parallel with table top 1 again.The center of gear 3 is wanted and can be regulated, with the concentricity of assurance and syringe and central shaft.Wire-delivering unit carriage 5 is fixed on the central shaft 15 of former knitting machine, and rotates with central shaft 15.Pulley transmission mechanism 11, belt tension governor motion 6, wire-delivering unit 12 all are fixed on the wire-delivering unit carriage 5.Wire-delivering unit 12 can the circumference that how much is evenly distributed on carriage 5 according to the inlet wire way on.Use belt 7 phase transmissions between each road.
According to the weaving requirement, what the defeated line amount of wire delivery mechanism must be with knitting mechanism is consistent with the line amount.Otherwise can't weave.The key that addresses this problem is exactly how to determine that wire-delivering unit is with respect to Trianguli gearratio i.
If the rotating speed of wire-delivering unit is n
1, Trianguli rotating speed is n
2Then wire-delivering unit is with respect to Trianguli gearratio i=n
1/ n
2
Because the defeated linear velocity π Dn of wire delivery mechanism
1Must with knitted parts use linear velocity LNn
2Equate.So π Dn
1=LNn
2I=n
1/ n
2=(LN)/(π D).
In the formula: N-syringe, dials total needle amount

12The diameter pulley of-wire-delivering unit 12
In order to be suitable for the needs (being the variation of loop length size) of different cultivars, will make the defeated line amount of wire delivery mechanism be convenient to regulate.From above formula, as can be seen, change loop length L, just need to change gearratio i.And the way that changes gearratio i generally has two kinds: a kind of is the number of teeth that changes planetary gear 13, and another kind is the diameter that changes belt pulley 10.The diameter pulley of the number of teeth of gear 3 and wire-delivering unit 12 then generally is changeless.If adopt first kind of mode, just need establish one group of density transform gear.When changing loop length, will change the gear of the corresponding number of teeth.Because the change of planetary gear 13 numbers of teeth will inevitably cause the change of two gear engagement position, thereby also just need readjust the centre-to-centre spacing between two gears.During conversion planetary gear 13, at first twist the fixed screw of scaling belt wheel transmission mechanism 11, take off pulley transmission mechanism 11, change needed planetary gear 13, utilize the oval hole on the pulley transmission mechanism 11 to realize the adjusting of the position of engagement, tighten fixed screw then and get final product.If the employing second way, the diameter that then only needs to change belt pulley gets final product.Adopt that a kind of mode all can cause the variation of belt tension, so be provided with belt tension governor motion 6 in this mechanism.When regulating belt tension, at first unscrew the fixed screw of belt tension governor motion 6, utilize the oval hole in this mechanism to realize moving of position, thereby reach the purpose of regulating belt tension.Tightening fixed screw then gets final product.
By facts have proved, this kind wire delivery mechanism is applicable to all triangle rotations and the fixing knitting machine of syringe.It can control defeated line amount exactly, and the inlet wire speed between the Lu Yulu is consistent, and the tension fluctuation of yarn also can reduce greatly, thereby make cloth cover clear, steady quality, the door width of cloth of fabric, density, grammes per square metre can reach control preferably, and the brute force of fabric and elasticity all increase to some extent.This mechanism adds storage yarn formula wire-delivering unit, can stop press-offing of fabric substantially.Can reduce the service life of pin consumption and prolongation machine.This mechanism design is reasonable, and is simple in structure, and former machine is changed not quite, and recondition expense is low, and installation, debugging and maintenance are all very convenient, are a kind of more satisfactory defeated line transmission mechanisms.
