Description

Technical Field

[0001] The utility model relates to the field of tension adjustment of a texturing machine, in particular to a tension adjustment device of a texturing machine. Background Art

[0002] Pre-oriented yarn (POY) produced by spinning is generally not used directly for weaving and must be post-processed before use. The work of texturing is to use POY as raw material, through stretching and deformation treatment, to transform POY into a drawn textured yarn (DTY) with relatively stable physical properties that can be directly used for weaving.

[0003] Through patent search, it is found that a tension adjustment device of a texturing machine with publication number CN217536265U rotates synchronously around the axis of the driving shaft through two adjustment rollers, so that the two adjustment rollers tighten the wire, and the wire bundle tension of the wire inside the texturing machine can be quickly adjusted. However, this adjustment method will quickly tighten the wire and change the wire bundle tension of the wire inside the texturing machine when the adjustment speed is fast, which may cause partial wire bundle breakage of the wire, resulting in burrs on the wire, resulting in a decrease in product quality, or the entire wire breakage causes the production line to stop, affecting the production progress. For this reason, we propose a tension adjustment device for a texturing machine to solve or improve the above problems. Utility Model Content

The first mounting block 11 is sleeved on the surface of the two-way screw rod 7 and is threadedly connected to the two-way screw rod 7. Two groups of first mounting blocks 11 are sleeved on the surface of the two-way screw rod 7. The two groups of first mounting blocks 11 are respectively located at the two ends of the two-way screw rod 7. When the two-way screw rod 7 rotates, it will drive the two groups of threaded first mounting blocks 11 to move in relative directions. The second mounting block 15 is fixed on the surface of the first mounting block 11. The interior of the second mounting block 15 is provided with a slot, and the surface of the slot is provided with a side slide groove. The first slider 14 is slidably installed in the side sliding groove opened inside the second mounting block 15. One end of the spring 13 is fixed to the surface of the first slider 14, and the other end is fixed to the slotted surface set inside the second mounting block 15. The surface of the first slider 14 is fixed with a limit rod 12, which is located inside the spring 13 and passes through the surface of the second mounting block 15. When the first slider 14 moves inside the second mounting block 15 through the side sliding groove, the limit rod 12 can ensure that the first slider 14 is centered inside the second mounting block 15, thereby ensuring the sliding stability of the first slider 14. The spring 13 can push the first slider 14 back to the initial position after the first slider 14 moves. The electric push rod 6 is fixed to the groove surface opened inside the turntable 2. The inner surface of the groove where the electric push rod 6 is located is provided with a side slide groove. The second slider 16 is slidably installed in the side slide groove. The top end of the output shaft of the electric push rod 6 is fixed to the surface of the second slider 16.

The second mounting block 15, the limit rod 12, the spring 13, the first slider 14 and the electric push rod 6, the second slider 16 are all arranged in two groups around the circumference.

[0022] The second bobbin 4 is installed on the top of the first slider 14 through a rotating shaft. When the second bobbin 4 moves, the installed first slider 14 will be driven to move. The first bobbin 3 is installed on the top of the second slider 16 through a rotating shaft. When the second slider 16 moves, the installed first bobbin 3 will be driven to move. The silk thread 5 is arranged on the surface of the first bobbin 3 and the second bobbin 4. The silk thread 5 passes through the surface of the first group of second bobbin 4, then passes through the surface of the two groups of first bobbin 3, and finally passes through the surface of the second group of second bobbin 4. The surfaces of the first bobbin 3 and the second bobbin 4 are both provided with wire grooves to prevent the silk thread 5 from falling off from the surfaces of the first bobbin 3 and the second bobbin 4 when the device is operating normally.

[0023] Working principle: when the device needs to be used, the spacing between the two groups of second spools 4 is adjusted by the second servo motor 9 according to the type and specification of the silk thread 5, so as to adapt to the silk threads 5 of different types and specifications, thereby improving the adaptability of the device; after adjusting to the appropriate position, the silk thread 5 passes through the surface of the first group of second spools 4, then passes through the surface of the two groups of first spools 3, and finally passes through the surface of the second group of second spools 4 and then is connected to the subsequent device; when the silk thread 5 moves, it will drive the two groups of second spools 4 and the two groups of first spools 3 to rotate, thereby reducing the friction between the second spools 4 and the first spools 3 on the silk thread 5, and reducing the problem of quality degradation of the silk thread 5 caused by friction; when the tension of the silk thread 5 needs to be adjusted, the first servo motor 1 drives the turntable 2 fixed on the top of the output shaft to rotate, so that the first spool 3 and the second spool 4 arranged in the turntable 2 are surrounded by The turntable 2 rotates around the center of the circle, thereby changing the tightness of the silk thread 5, thereby adjusting the tension of the silk thread 5. When the turntable 2 rotates, the electric push rod 6 pushes the second slider 16 to move and drives the first spool 3 to move, so that the tightness of the silk thread 5 can also be adjusted during the rotation of the turntable 2, avoiding drastic fluctuations in the tightness of the silk thread 5 when the turntable 2 rotates. At the same time, when the silk thread 5 suddenly changes in tightness during the adjustment process and the electric push rod 6 cannot respond in time, the tightening or loosening of the silk thread 5 will cause the second spool 4 to drive the first slider 14 to move, thereby offsetting the sudden fluctuation in the tightness of the silk thread 5, reducing the problem of partial breakage of the silk thread 5 due to tension fluctuations, resulting in burrs on the silk thread 5, resulting in a decline in product quality, or the breakage of the entire silk thread 5 causing the production line to stop, affecting the production progress.
