Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a tension-adjustable false twist machine. Background Technology

[0002] False twisting machines are used in the production and processing of yarn. The purpose of this equipment is to generate twisting on the yarn through disc-shaped friction elements. The purpose is to increase the overall volume or elastic elongation of the originally smooth monofilament. False twisting machines usually include three friction spindles, whose rotation axes are set in an equilateral triangle structure. Each friction spindle is usually driven by a belt.

[0003] For example, Chinese Patent (CN207672193U) discloses a false twisting machine for silk threads, including a mounting base fixed on a production line mounting beam, a front bearing seat and a rear bearing seat fixed on the mounting base, a front rotating shaft disposed in the front bearing seat, a front friction spindle disposed at the upper end of the front rotating shaft, a rear rotating shaft disposed in the rear bearing seat, a rear friction spindle disposed at the upper end of the rear rotating shaft, a roller fixedly disposed at the lower end of the rear rotating shaft, and a conveyor belt for driving the roller to rotate disposed behind the roller, and a silk thread sleeve rod disposed between the front friction spindle and the rear friction spindle, a support rod disposed on the mounting base, a sleeve rod magnetic block fixedly disposed on the support rod, the silk thread sleeve rod pressing against the sleeve rod magnetic block, and the two ends of the silk thread sleeve rod respectively cooperating with the front friction spindle and the rear friction spindle to rotate. This utility model has a high degree of fit, is not easily damaged, has a long service life, and can be widely used in the field of false twisting of silk threads.

[0004] The above solution also has the following technical shortcomings. The above solution is convenient for adjusting the tension of the false twisting machine. The front and rear shafts of the above solution are fixedly installed and cannot be moved relative to each other. This makes the relative distance between the front and rear friction spindles fixed, which makes it inconvenient to adjust the tension of the false twisting machine. Based on this, a false twisting machine with adjustable tension is proposed. Utility Model Content

A right rotating shaft 4 is located on the distance adjustment mechanism 200, and a rear rotating shaft 5 is located on the tensioning mechanism 300. A first motor 6 is located on the front side of the top of the base 1. A left rotating shaft 7 is fixed to the output shaft of the first motor 6. A transmission assembly 800 is located on the right rotating shaft 4, the left rotating shaft 7, and the rear rotating shaft 5. A left friction spindle 9 is fixed to the outer surface of the left rotating shaft 7, and a right friction spindle 10 is fixed to the outer surface of the right rotating shaft 4. The transmission assembly 800 includes a driving wheel 801 fixed to the outer surface of the left rotating shaft 7, a first driven wheel 802 fixed to the outer surface of the right rotating shaft 4, a second driven wheel 803 fixed to the outer surface of the rear rotating shaft 5, and a transmission belt 804 that is connected to the outer surfaces of the driving wheel 801, the first driven wheel 802, and the second driven wheel 803.

[0023] In this embodiment, the distance adjustment mechanism 200 is used to adjust the relative distance between the right friction spindle 10 and the left friction spindle 9, and the tensioning mechanism 300 is used to enable the transmission assembly 800 to operate normally after the right friction spindle 10 is adjusted. The transmission assembly 800 is used to maintain the synchronous rotation of the left rotating shaft 7 and the right rotating shaft 4.

[0024] It should be noted that the working principles of other structures of the false twisting machine are relatively mature existing technologies, and therefore will not be explained in the instruction manual.

[0025] Please see Figure 1-3 To facilitate the adjustment of the relative distance between the left friction spindle 9 and the right friction spindle 10, the distance adjustment mechanism 200 in this embodiment includes a second motor 201 fixed to the right side of the base 1. The output shaft of the second motor 201 is fixed with a screw 202. A moving groove is provided on the front side inside the base 1. The left end of the screw 202 is rotatably connected to the left side of the moving groove. Two moving blocks 203 are threadedly connected to the outer surface of the screw 202. A moving rod 204 is fixed to the top side of the moving block 203. A moving plate 205 is fixed to the top of the two moving rods 204. A first bearing seat is fixed to the top of the moving plate 205. The bottom end of the right rotating shaft 4 rotates inside the first bearing seat.

[0026] In this embodiment, the distance adjustment mechanism 200 can drive the screw 202 to rotate via the second motor 201. The screw 202 is used to drive the moving block 203 to move left and right. The moving block 203 is used to drive the moving rod 204 and the moving plate 205 to move together. The moving plate 205 is used to drive the right friction spindle 10 to adjust its position.

[0027] It should be noted that a rectangular hole is provided on the top side of the chute, and the moving rod 204 can limit the moving block 203 by sliding within the rectangular hole.

[0028] Please see Figure 1 and Figure 4 To facilitate the normal operation of the transmission belt 804 after the second driven wheel 803 moves, the tensioning mechanism 300 in this embodiment includes two fixed rods 301 fixed inside the rear side of the base 1. A slider 302 is slidably connected to the outer surface of the fixed rods 301. Two sliding grooves are opened inside the rear side of the base 1. The two fixed rods 301 are fixed to the left and right sides of the corresponding sliding grooves. The slider 302 slides in the sliding groove. A spring 303 is sleeved on the outer surface of the fixed rods 301. A sliding rod 304 is fixed to the top of the slider 302. A sliding plate 305 is fixed to the top of the two sliding rods 304. A second bearing seat is fixed to the top of the sliding plate 305. The bottom end of the rear rotating shaft 5 rotates in the second bearing seat.

[0029] In this embodiment, the tensioning mechanism 300 can support the slider 302 through the elastic force generated by the deformation of the spring 303. The slider 302 can then support the sliding rod 304, the sliding plate 305 and the rear rotating shaft 5, thereby generating a certain compressive force between the second driven wheel 803 and the transmission belt 804, so that the transmission belt 804 can be fitted onto the second driven wheel 803.

[0030] It should be noted that the slider 302 can be limited by sliding on the outer surface of the fixed rod 301. The slider 302 can limit the sliding rod 304 and the sliding plate 305, thereby keeping the rear rotating shaft 5 vertical.

[0031] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0032] The working principle of the above embodiments is as follows:

[0033] When the tension of the false twist machine needs to be adjusted, the second motor 201 is started. The output shaft of the second motor 201 drives the screw 202 to rotate. The screw 202 drives the moving block 203 to move left and right. The moving block 203 drives the moving rod 204 and the moving plate 205 to move together. The moving plate 205 drives the right rotating shaft 4 and the first driven wheel 802 to move. At the same time, the spring 303 is further compressed or undergoes a certain degree of deformation recovery. The slider 302 moves forward or backward adaptively. The slider 302 drives the sliding rod 304 and the sliding plate 305 to move. The sliding plate 305 drives the rear rotating shaft 5 and the first driven wheel 802 to move together. The two driven wheels 803 are adjusted accordingly so that the transmission belt 804 keeps in contact with the outer surfaces of the driving wheel 801, the first driven wheel 802, and the second driven wheel 803. When the device needs to work normally, the first motor 6 is started. The output shaft of the first motor 6 drives the left rotating shaft 7 to rotate. The left rotating shaft 7 drives the driving wheel 801 to rotate. The driving wheel 801 drives the transmission belt 804 to rotate. The transmission belt 804 drives the first driven wheel 802 and the second driven wheel 803 to rotate. The first driven wheel 802 drives the right rotating shaft 4 to rotate, so that the left friction spindle 9 and the right friction spindle 10 rotate synchronously.
