Description

TECHNICAL FIELD

[0001] The utility model relates to a yarn unwinding device for a twisting machine. BACKGROUND

[0002] The twisting machine, also known as a double-twisting machine, is a kind of twisting equipment, and is essentially a kind of parallel line equipment (a plurality of strands are combined into one strand), called a parallel line machine, without specific English and Chinese names, and can realize one-turn two-twist, with the twisting efficiency being improved by several times compared with traditional twisting equipment. The winding capacity is increased, the winding quality is greatly improved, the layer height is low, and the operation is suitable.

[0003] Most of the existing yarn unwinding devices do not have the function of combing the yarn, and the textile yarn is generally rough, and the manual combing degree cannot reach a certain standard, which will cause poor combing effect and easy formation of neps.

In the related technology, a combing ruler is used to comb the yarn, the yarn is threaded through the tooth gap of the combing ruler, the tooth body of the combing ruler is rubbed on the outside of the yarn, and the yarn is combed and smoothed. However, when the device is used for a long time, a large amount of lint will accumulate in the tooth gap of the combing ruler, which will affect the combing effect of the yarn and cause inconvenience in use.

At the same time, when the sliding block 24 moves with the fixed seat 222, the push plate 25 will gradually move away from the inclined sliding block 26, at this time the inclined sliding block 26 is no longer pressed, and the inclined sliding block 26 will reset under the action of the spring outside the first guide rod 27, so as to drive a support frame 15 to move away from the unwinding roller 14, and then the one end of the yarn roll is released from the limitation, so as to facilitate the replacement of the yarn roll. After the installation of the yarn roll is completed, the driving motor 211 is started, the lead screw 212 drives the adjusting block 23 to move towards the support seat 12, and in the movement process of the sliding block 24, the push plate 25 will press the inclined surface of the inclined sliding block 26, so as to drive the inclined sliding block 26 and the support frame 15 to move towards the unwinding roller 14, and the support frame 15 limits one side of the yarn roll outside the unwinding roller 14, so as to facilitate use.

[0037] In some embodiments, the driving mechanism 21 comprises: a driving motor 211 fixedly connected to one end of the support seat 12; a lead screw 212 rotationally connected to the inside of the support seat 12 and the limiting seat 13, one end of the lead screw 212 is fixedly connected to the output end of the driving motor 211, and the outside of the lead screw 212 is threadedly connected with the adjusting block 23, and the lead screw 212 can be driven to rotate forward or reverse through the starting of the driving motor 211, and then the adjusting block 23 is driven to move through the action of the threaded connection, so as to drive the fixed seat 222 to move, and then the fixed seat 222 is conveniently moved to the suspension for cleaning.

[0038] In some embodiments, the carding mechanism 22 comprises: a first carding tooth 221, which is slidingly connected to the top of the limiting seat 13, and one side of the bottom of the first carding tooth 221 is fixedly connected with the adjusting block 23, and the other side of the bottom of the first carding tooth 221 is fixedly connected with the sliding block 24; a fixed seat 222, which is fixedly connected to one side of the first carding tooth 221; an adjusting threaded rod 223, which is rotationally connected to the inside of the fixed seat 222; and a second carding tooth 224, which is slidingly connected to the inside of the fixed seat 222, and the adjusting threaded rod 223 is threadedly connected with the second carding tooth 224.

[0039] In use, when the yarn is carded, since different yarn diameters are different in size, after the yarn passes through the tooth gap of the first carding tooth 221 and the second carding tooth 224, the position of the second carding tooth 224 needs to be adjusted by rotating the adjusting threaded rod 223 until the edges of the second carding tooth 224 and the first carding tooth 221 surround the yarn and do not clamp the yarn, at which time the fluff on the edge of the yarn can be carded by the edges of the first carding tooth 221 and the second carding tooth 224 when the yarn is unwound, facilitating operation.
