Abstract

The utility model relates to a winding device on a textile machine. The technical problem to be solved is to provide an improved winding roller, and the roller is characterized by no slippage of silk yarn motion, precise control of silk yarn twist and good product quality. The technical scheme adopted by the utility model is that the dual-drive winding roller comprises a large roller and a small roller which are separated by a certain distance and arranged in parallel, as well as a driving gear which is driven by a power device and meshed with a gear of the large roller for driving the large roller to rotate. The dual-drive winding roller is characterized in that the gear of the small roller is coaxially arranged at one end of the small roller, an idle gear is further arranged between the gear of the large roller and the gear of the small roller, and the idle gear is respectively meshed with the gear of the small roller and the gear of the large roller, thereby leading the large roller and the small roller to keep at the same surface linear speed.

Description

Two driving Wound-up rollers

Technical field

The utility model relates to the coiler device on a kind of textile machine, especially the Wound-up roller on the composite twisting machine.

Background technology

The operation principle of the Wound-up roller of existing composite twisting machine such as Fig. 4, shown in Figure 5: the transmission of power of motor output is to the driving gear in each unit of twisting thread, driving gear meshes again and the big coaxial driven gear of roller, make big roller 2 rotate, two rhizoid lines after drive merging thus down move and (go up two rhizoid line S1 and the S2 that spindle 11-1 and 11-2 go up unwinding from two and be merged into silk thread S through behind the guide chase ring 12, walk around big roller 2 then simultaneously and draw 1 some circles with small gross), by all the other mechanisms (comprise following spindle 14 that tengential belt 13 down drives and the steel that matches with following spindle make 15 and steel make the plate elevating mechanism) carry out retwist.The defective of this kind Wound-up roller is: because small gross draws 1 to be passive movement, the some circle silk thread S that twine by periphery drag and rotate, thereby small gross pulls into the resistance into the silk thread motion, make silk thread when motion, produce skidding (silk thread and big surface of roller produce relative slip) unavoidably, cause the twist error of retwist product bigger thus, directly influenced product quality.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of Wound-up roller is provided, and this roller should have the characteristics that the silk thread motion can not skidded, the silk thread twist is controlled accurate and good product quality.

The technical solution adopted in the utility model is:

Two driving Wound-up rollers, comprise some distances and big roller that be arranged in parallel and little roller at interval, and be subjected to the power set driving and mesh the driving gear that big roller gear orders about big roller rotation, the coaxial small gross that is equipped with of an end that it is characterized in that described little roller draws gear, big roller gear and small gross draw a carrier gear also are set between the gear, this carrier gear draws gear and big roller gears engaged with small gross respectively, makes big roller and small gross draw the linear resonance surface velocity that keeps identical.

Described small gross draws gear and small gross to draw the both sides that are positioned at winding stand respectively.

When the utility model used, still the silk thread that the unwinding from the last spindle more than two or two is got off merged, and walks around big roller 2 then simultaneously and draws 1 some circles with small gross, then by spindle and steel make plate mechanism carry out retwist down; But because small gross draws 1 from original being changed into by gear drive by the silk thread driving, big roller 2 draws 1 to keep identical linear resonance surface velocity with small gross, so the motion of silk thread is accurately orderly, has eliminated the skidding that in the past existed fully; Make the twist error of retwist product not exist thus, guaranteed the high-quality product of twisting thread.

The specific embodiment

Two driving Wound-up rollers comprise that the some distances in interval and the big roller 2 and the small gross that be arranged in parallel draw 1, and are subjected to power set driving and engagement to order about the driving gear 5 of big roller gear 4 motions that driving gear 5 is by the big roller gear 4 of small offence axle gear 6 drives; Big roller 2 is because coaxial fixing with big roller gear 4, thereby just rotates.The utility model draws gear 1-1 at the coaxial fixedly small gross of an end of described little roller, and small gross draws gear 1-1 and small gross to draw 1 both sides that are positioned at winding stand 8 respectively; Big roller gear and small gross draw a carrier gear 7 are set again between the gear, and this carrier gear draws gear and big roller gears engaged with small gross respectively, makes big roller and small gross draw the linear resonance surface velocity that keeps identical.

Claims

1, two driving Wound-up rollers, comprise some distances and big roller (2) that be arranged in parallel and little roller (1) at interval, and be subjected to the power set driving and mesh the driving gear (5) that big roller gear (4) orders about big roller rotation, the coaxial small gross that is equipped with of an end that it is characterized in that described little roller draws gear (1-1), big roller gear and small gross draw a carrier gear (7) also are set between the gear, this carrier gear draws gear and big roller gears engaged with small gross respectively, makes big roller and small gross draw the linear resonance surface velocity that keeps identical.

2, two Wound-up roller that drives according to claim 1 is characterized in that described small gross draws gear and small gross to draw the both sides that are positioned at winding stand (8) respectively.
