Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of yarns, and relates to a processing method of polyester elastic yarn. BACKGROUND

[0002] A false twister (also known as a spinning machine) is a mechanical device used for spinning fibers into yarn. It is one of the key devices in the textile industry.

[0003] The working principle of the false twister is to stretch, twist and refine the fiber material through a series of processes to form a continuous yarn.

[0004] The existing false twister generally comprises a base, a roller shaft one, a roller shaft two and ceramic friction discs, the roller shaft one and the roller shaft two are both axially fixed on the base and can rotate, the number of the ceramic friction discs is several, the roller shaft one is uniformly distributed with the ceramic friction discs along the length direction, and the roller shaft two is uniformly distributed with another several ceramic friction discs along the length direction.

[0005] When the yarn, such as polyester elastic yarn, passes through the roller shaft one and the roller shaft two, the polyester elastic yarn is in contact with the rotating ceramic friction discs, and the rotating ceramic friction discs finally make the polyester elastic yarn stable twist.

[0006] However, since the distance between the roller shaft one and the roller shaft two is fixed, different false twisters need to be used for different yarns, resulting in poor applicability. SUMMARY

[0007] The purpose of the present application is to provide a processing method of polyester elastic yarn with high applicability in view of the above problems existing in the prior art.

[0008] The purpose of the present application can be achieved by the following technical solutions:

[0010] A, leading-in: leading in the polyester elastic yarn to the false twister, and the ceramic disc in the false twister is rotated to frictionally rotate and twist the polyester elastic yarn;

[0011] B, adjusting: the ceramic discs are connected to the roller shaft to form a twisting unit, a plurality of twisting units are adjacently arranged to form a twisting part for stably twisting the polyester elastic yarn, and the distance between the two adjacent twisting units is adjusted according to different raw materials of the polyester elastic yarn to ensure the stable and normal twisting of the polyester elastic yarn.

[0012] The distance between adjacent twisting units can be adjusted according to actual conditions, thus effectively improving the applicability in the processing of polyester stretch yarn.

[0013] Specifically, the polyester stretch yarn is stably twisted after passing through the rotating ceramic disc.

[0014] In the processing method of the polyester stretch yarn, the false twister comprises a connecting block, a fixed block, a movable block, a roller shaft one and a roller shaft two and a ceramic disc, the connecting block is in the shape of a long block, the connecting block is provided with a guide cavity extending from one end to the middle part, the fixed block and the movable block are embedded in the guide cavity of the connecting block, and a pre-tightening positioning mechanism is further provided between the movable block and the connecting block, the fixed block can abut against the end part of the guide cavity under the action of the pre-tightening positioning mechanism, and the movable block can be positioned at the set position of the connecting block under the action of the pre-tightening positioning mechanism, the inner end of the roller shaft one is fixed on the movable block in the axial direction, and the roller shaft one is provided with a plurality of ceramic discs along the length direction, the inner end of the roller shaft two is fixed on the fixed block in the axial direction, and the roller shaft two is provided with a plurality of ceramic discs along the length direction.

[0015] In the processing method of the polyester stretch yarn, the movable block and the fixed block are matched with the guide cavity, and the movable block and the fixed block can translate along the length direction of the guide cavity.

[0016] The fixed block and the movable block are matched with the guide cavity, which can stably embed the fixed block and the movable block in the connecting block, and the movable block and the fixed block can stably translate along the guide cavity.

[0017] The roller shaft one is connected to the movable block, and the roller shaft two is connected to the fixed block, and the fixed block and the movable block can be stably positioned and connected to the connecting block under the action of the pre-tightening positioning mechanism.

[0018] Finally, the roller shaft one and the roller shaft two are stably positioned and connected to the connecting block indirectly.

[0019] In the processing method of the polyester stretch yarn, the pre-tightening positioning mechanism comprises a connecting rod, a spring one, a spring two and a clamping piece, the inner end of the connecting rod is fixed to the fixed block, the middle part of the connecting rod is arranged on the movable block, the spring one is sleeved on the connecting rod and the two ends of the spring one act on the fixed block and the movable block respectively, the side wall of the guide cavity is provided with a recessed positioning hole, the spring two and the clamping piece are located at the positioning hole, and the clamping piece has a tendency to abut against and clamp the movable block under the elastic force of the spring two.

[0020] The fixed block has a tendency to abut against the bottom part of the positioning cavity under the elastic force of the spring one, and the clamping piece has a tendency to clamp the movable block under the elastic force of the spring two, and the structure finally stably positions and connects the fixed block and the movable block in the connecting block.

[0021] In the processing method of polyester elastic yarn, a cylindrical adjusting cylinder is further included, the adjusting cylinder has a plurality of concave positioning notches on its outer side along the axial direction, the clamping member has a tendency to be clamped in any one of the positioning notches under the elastic force of the second spring, and the connecting rod is arranged in the adjusting cylinder.

[0022] Since the size of the movable block is limited, the positioning notches are arranged on the adjusting cylinder, and the clamping member is embedded in the positioning notches to stably connect the adjusting cylinder and the connecting block. The movable block has a tendency to abut against the adjusting cylinder under the elastic force of the first spring, and finally the movable block is positioned in the connecting block.

[0023] In the processing method of polyester elastic yarn, the connecting rod has a scale mark on the outer end.

[0024] The scale mark on the connecting rod can intuitively check the adjustment degree of the movable block.

[0025] In the processing method of polyester elastic yarn, the connecting block further has a motor, the rotating shaft of the motor is fixedly connected with the roller shaft one, and the motor further includes a transmission belt, a tension pulley and a pre-tightening assembly. The tension pulley is fixedly connected with the connecting block in the axial direction, the transmission belt is sleeved on the roller shaft one, the roller shaft two and the tension pulley, and the pre-tightening assembly can exert a pre-tightening pressing force on the transmission belt between the roller shaft one and the tension pulley.

[0026] During the continuous rotation of the roller shaft one driven by the motor, the roller shaft two will also rotate together under the action of the transmission belt.

[0027] The pre-tightening assembly can always tension the transmission belt, so as to avoid the loosening of the transmission belt after the position adjustment of the movable block.

[0028] In the processing method of polyester elastic yarn, the pre-tightening assembly includes a guide cylinder, a top rod and a third spring. The third spring and the inner end of the top rod are located in the guide cylinder. Under the elastic force of the third spring, the outer end of the top rod has a tendency to protrude out of the guide cylinder and abut against the transmission belt between the roller shaft one and the tension pulley.

[0029] The guide cylinder and the top rod cooperate to stably translate the top rod in the transverse direction. Of course, under the action of the third spring, the top rod always has a tendency to abut against the transmission belt, so as to stably tension the transmission belt.

[0030] In the processing method of polyester elastic yarn, the outer end of the top rod is connected with a press wheel, and the press wheel abuts against the transmission belt between the roller shaft one and the tension pulley.

[0031] The press wheel is movably connected with the outer end of the top rod, and the rotatable press wheel effectively reduces the friction resistance between the transmission belts.

[0032] Compared with the prior art, the processing method of the polyester elastic yarn has higher applicability because the distance between the two twisting units can be adjusted according to actual conditions.

[0033] Meanwhile, the two twisting units are driven by the same power, and the transmission belt can always keep in a tension state after the positions of the two twisting units are changed, so that the stability is also relatively high, and the processing method has high practical value.
