Abstract
The utility model relates to a gray cloth drafting device for a circular knitting machine, composed of a front drafting roller, a back drafting roller, a fender roller, a batching cylinder, a pinch roller, etc. The pinch roller is matched with the back drafting roller. The three central points of the front drafting roller, the back drafting roller and the pinch roller are not on the same straight line. The effective wrap angle alpha of the grey cloth of the back drafting roller is larger than 180 DEG. The utility model has the reasonable layout of the three rollers, causes each layer of the grey cloth to have the approximate drafting force when the double-layer grey cloth is in the process of drafting, increases knitting uniformity and reliability and improves cloth face quality.
Description
The utility model relates to the batching drawing system of circular knitting machine, and particularly relating to braiding is the circular knitting machine grey cloth pulling device of raw material with wool, silk.
Circular knitting machine is rolled onto grey cloth on the cloth tube by the batching system of circular knitting machine bottom after syringe is woven into grey cloth.This batching process is not only in order to collect grey cloth, but a suitable traction force must be arranged, and the uniformity of this traction force will directly have influence on the weaving quality of syringe.Therefore, a desirable grey cloth pulling device being arranged, is crucial.
The grey cloth draw-off mechanism of existing circular knitting machine can be divided into two roll shape formulas or in-line three roller tractive forms two classes by the combination difference of its pulling roll: the former as supporting on the little circular knitting machine of jacquard weave or each series such as interlock machine or rib knitting machine; The latter is general supporting on large circle machine.When columnar grey cloth is rolled onto on the pulling roll, just become inside and outside two-layerly, internal layer is attached on the pulling roll, and frictional force is big, and skin is attached on the internal layer, frictional force is little.Especially when the raw material of grey cloth adopted the fiber of surperficial smoother such as wool, silk, this phenomenon was outstanding especially.Though existing structure has two pulling roll, the S-type trend of grey cloth, the chance that each layer all once directly contacts with pulling roll, but owing to be hard-pressed bale power (be that traction force is big, the grey cloth hard-pressed bale is on preceding pulling roll surface) from syringe to preceding pulling roll, and be that bale breaking power (is that traction force is little from the back pulling roll to fabric drum, the grey cloth bale breaking is on pulling roll surface, back), therefore, the internal layer frictional force on pulling roll surface is big before being attached to, traction force is also big, and extending on the syringe grey cloth, corresponding traction force is also big on one side; And the outer field frictional force of pulling roll is little before being attached to, and traction force is also little, and the traction force that extends to corresponding one side grey cloth on the syringe is little.Thus, cause that the traction force of syringe circumference grey cloth is inhomogeneous, influenced knitting quality.The above-mentioned defective of analyzing existing two roll shape formulas.And existing three roller tractive forms are the little shortcomings of traction force for the outer grey cloth of pulling roll before overcoming, three roller in-lines are arranged, three centers of circle are on same straight line, consequently the frictional force of outer grey cloth obtains increasing, but the frictional force of internal layer has increased again simultaneously, therefore, the difference in size of inside and outside layer frictional force is not corrected, and the traction force of promptly inside and outside layer grey cloth does not still have balance.
The purpose of this utility model is that a kind of grey cloth to the back pulling roll of design clamps, and makes it increase back pulling roll internal layer grey cloth frictional force, exists traction force inhomogeneous thereby reduce two-layer grey cloth, and influences the grey cloth pulling device of the circular knitting machine of knitting quality.
The technical scheme of the grey cloth pulling device of the utility model circular knitting machine is: be made up of institutes such as preceding pulling roll, back pulling roll, retaining roller and fabric drums, it is characterized in that having a pinch roll, pinch roll matches with the back pulling roll, the on line of preceding pulling roll, back pulling roll, three central points of pinch roll is not on same straight line.Arrange if the central point of three rollers on same straight line, is in-line, grey cloth is too little at effective cornerite of back pulling roll, is worthless.
The grey cloth pulling device of the utility model circular knitting machine, grey cloth the back pulling roll the cornerite starting point to pinch roll with the back pulling roll bite, 2 respectively with the on line angle α of back pulling roll center O greater than 180 °, be grey cloth at effective cornerite of back pulling roll greater than 180 °, make back pulling roll frictional force like this near preceding pulling roll frictional force.
The utility model discloses a kind of grey cloth pulling device of circular knitting machine, compared with the prior art, it is rationally distributed to have three rollers, make of the traction force phenomenal growth of back pulling roll to grey cloth, double-deck grey cloth each layer traction force trend in traction process is even, thereby improved braiding uniformity, reliability, improved the quality of cloth cover.
Fig. 1 is the grey cloth pulling device schematic layout pattern of the utility model circular knitting machine;
Fig. 2 is that the forward and backward roller of the utility model circular knitting machine grey cloth pulling device is to grey cloth friction force analysis figure;
Fig. 3 is that existing two roller is to grey cloth friction force analysis figure;
Fig. 4 is that prior art three roller in-lines are arranged each roller stock cloth friction force analysis figure.
Below in conjunction with Fig. 1-Fig. 4 embodiment of the present utility model is done detailed explanation.
1, syringe; 2, grey cloth; 3, retaining roller; 4, preceding pulling roll; 5, back pulling roll; 6, pinch roll; 7, fabric drum; 8, bite; 9, back roller stock cloth cornerite starting point; 10, preliminary roller frictional force; 11, back roller frictional force; 12, double-roll type preliminary roller frictional force; 13, roller frictional force behind the double-roll type; 14, pressure roller; 15, three-roller type preliminary roller frictional force; 16, roller frictional force after the three-roller type.
The utility model is a kind of grey cloth pulling device of circular knitting machine, the grey cloth 2 that gets off from syringe 1 passes through retaining roller 3, the outside of pulling roll 4 before being entangled in earlier, the outside of pulling roll 5 after twining again, to fabric drum 7, a pinch roll 6 is arranged from back pulling roll 5 on pulling roll next door, back.As shown in Figure 1, grey cloth 2 to the bite 8 that pinch roll 6 and back pulling roll 5 are formed, is the effective cornerite of grey cloth in the back pulling roll in back pulling roll 5 cornerite starting points 9, and wrap angle sigma is greater than 180 °.Analyze as Fig. 2, preceding pulling roll compares with the frictional force 11 of back pulling roll to grey cloth the frictional force 10 of grey cloth, and both are close.As shown in Figure 3, existing two roll shape formulas, the frictional force of each root roller is different, and double-roll type preliminary roller frictional force 12 substantially exceeds roller frictional force 13 behind the double-roll type.Again from Fig. 4 analysis, prior art three roller in-lines are arranged, pressure roller 14 matches with preceding pulling roll 4, frictional force increases in preceding pulling roll, be that three-roller type preliminary roller frictional force 15 substantially exceeds back roller frictional force 16, so added pressure roller 14, do not overcome uneven problem, i.e. not increase of the effective cornerite of grey cloth of pulling roll afterwards around the grey cloth traction force under the syringe.
