Abstract
The utility model relates to a continuous drawing and winding device for a weft knitting machine, comprising a stepless speed adjusting device used for adjusting the drawing speed. The utility model is characterized in that the stepless speed adjusting device is composed of two reducing belt pulleys (5) and a driving belt (7). A plurality of circumferentially distributed slide blocks (53) are clamped tightly between a screw adjusting disc (51) and a grooved disk (52), which forms the reducing belt pulleys (5). Through the adjustment of diameters of the two reducing belt pulleys, the transmission ratio of the stepless speed adjusting device can be changed and the drawing speed of the two drawing rollers can be equal as the weaving speed, which improves the quality of weaving grey cloth.
Description
The utility model relates to a kind of knitting circular knitting machine, particularly relates to the continuous drawing and winding device of knitting circular knitting machine.
The pulling device of existing knitting circular knitting machine is of a great variety, but with regard to its tractive mode, can divide intermittently drawing-type and drawing-type two big classes continuously.So-called intermittently drawing-type mainly is that the intermittent motion mechanism that utilizes eccentric link or cam to constitute realizes the circle latitude machine woven grey cloth of one or many pulling that rotates a circle, therefore can't satisfy even, continuous weaving speed requirement, greatly influence the quality of grey cloth.So-called drawing-type continuously mainly contains two kinds, the first round belt self-adjusting that skids, and it two is additional motor formulas.The round belt self-adjusting that skids is to utilize the big round belt of the too fast resistance of draw rate to draw cunning, and draw rate is crossed the little round belt of slow resistance and Pulley and is synchronized with the movement the automatic compensation draw rate.Because any machinery is in operation process, resistance is constantly to change all the time, therefore utilizes round belt to draw sliding principle to come the automatic compensation draw rate, can't guarantee the draw rate uniformity all the time at all.In addition, employed round belt has joint, very easily fracture damage.The additional motor formula is to adopt the rotating speed of adjusting additional motor to make draw rate and weaving speed realize that synchronously continuous tractive batches, though it can overcome the existing defective of above-mentioned various drawing and winding device, has complex structure, the high obvious deficiency of cost.
In view of there is above-mentioned deficiency in prior art, the purpose of this utility model provides the continuous drawing and winding device of a kind of simple in structure, cheap knitting circular knitting machine.
To achieve these goals, technical solution of the present utility model is:
The continuous drawing and winding device of a kind of knitting circular knitting machine, comprise the stepless speed adjusting gear of adjusting draw rate, it is characterized in that this stepless speed adjusting gear is made of two reducing belt pulleys and a driving band, described reducing belt pulley mainly is that some slide blocks that circumferentially distribute of clamping constitute between a double helix adjustment disk and slotted disk.The inner end surface of described adjustable diameter and screw adjusting dish is provided with etc. and advances plug helix; The inner end surface of described slotted disk is provided with the guide groove of radiation; One side of described slide block is provided with one and puts in the protruding nail in the set plug helix on the adjustable diameter and screw adjusting dish, and opposite side is provided with two and puts in the protruding nail in the set guide groove on the slotted disk.Rotate the adjustable diameter and screw adjusting dish, all slide blocks are synchronized with the movement along described guide groove and change the distribution circle diameter, also promptly change working diameter, thereby reach the purpose that changes transmitting ratio.
Because stepless speed adjusting gear described in the utility model has used two reducing belt pulleys, therefore have following advantage than prior art:
1, transmitting ratio steady this, make its woven product of institute even, smooth, plentiful;
2, simple and compact for structure, with low cost;
3, reliable operation, fault rate is low, and maintenance load is little;
4, comformability is good, both can be used for the transformation of old equipment, also can be used for the improvement design of new engine;
5, stable working, noiseless;
6, there is not the energy consumption of additional motor, power-saving.
Below in conjunction with accompanying drawing and a preferred embodiment the utility model is described in detail.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiments of the utility model;
Fig. 2 advances the structural representation of helix line for set grade on adjustable diameter and screw adjusting dish 51 inner end surfaces in the reducing belt pulley 5 among Fig. 1;
Fig. 3 is the distribution schematic diagram of the slide block in the reducing belt pulley 5 53 among Fig. 1;
Fig. 4 is the structural representation of set radial guide groove on 52 inner end surfaces of the slotted disk in the reducing belt pulley 5 among Fig. 1.
Embodiment:
Referring to Fig. 1, present embodiment is to utilize stepless speed adjusting gear described in the utility model, drawing and winding device in the existing knitting circular knitting machine is improved forming.
With reference to Fig. 1,2,3 and 4, reducing belt pulley 5 be that 12 circumferential well-distributed slide blocks 53 of clamping constitute between an adjustable diameter and screw adjusting dish 51 and slotted disk 52.Referring to Fig. 3 and 4, one side of every slide block 53 is provided with a protruding nail that puts in the plug helix set on the adjustable diameter and screw adjusting dish 51, opposite side is provided with two protruding nails that put in the radial guide groove set on the slotted disk 52, rotating adjustable diameter and screw adjusting dish 51 can drive 12 slide blocks 53 and slide synchronously along guide groove set on the slotted disk 52 by putting in protruding nail in the plug helix, change 12 slide block 53 distribution circle diameters, thereby change the effect of its working diameter.
Referring to Fig. 1, the inboard of slotted disk 52 is provided with boss, in the middle of adjustable diameter and screw adjusting dish 51 is enclosed within on its boss 12 slide blocks are clamped in and compress with nut 54.During adjusting, unclamp nut 54 earlier and rotate adjustable diameter and screw adjusting dish 51 again, fastening nut 54 gets final product again at last.
Referring to Fig. 1, for simplified structure, reduced volume, the utility model is provided with ratchet as the edge of the slotted disk 52 of the reducing belt pulley 5 of negative pulley wheel, form a ratchet, this ratchet combined with ratchet 8 constitute a ratchet device, when preventing the board stall, pulling roll 9 reversings under the effect of grey cloth.Referring to Fig. 1, the utility model is provided with involute shape tooth on the edge as the reducing belt pulley 5 of driving pulley, form a gear, to transmit imput power.
Referring to Fig. 1, reducing belt pulley 5 skies as negative pulley wheel in this example are enclosed within on the crank shaft 6, and the other end of this crank shaft 6 is fixedly on the wallboard 10.When install adjusting, rotate the back lash that this crank shaft 6 can be adjusted itself and gear 4.
Implementation method beyond the utility model is above-mentioned can be utilized known technology and carry out in conjunction with Fig. 1.
Below in conjunction with Fig. 1 working process of the present utility model is described below:
Referring to Fig. 1, when the operation of circle latitude machine, whole device described in the utility model rotates around ground shaft gear 1, by gear 2 and wheel 16 power is divided into the two-way transmission.Leading up to transverse axis 3, gear 4 reaches the stepless adjuster of being made up of two reducing belt pulleys 5 and driving band 7, drives two pulling roll 9 and relatively rotates the woven grey cloth of tractive.Referring to Fig. 1, adjust the diameter (diminishes, and it is big that another becomes) of two reducing belt pulleys 5 simultaneously, change transmitting ratio, can adjust two pulling roll 9 speed in relative rotation, change draw rate, draw rate is equated with weaving speed.Referring to Fig. 1, another road reaches belt pulley 12 by transverse axis 15 and belt pulley 14 through round belt 13 and drives work beam 11 rotations, batches the grey cloth of being sent here by two pulling roll 9.
