[0028] Among them; the guide assembly 3 further includes a cross arm 301, a U-shaped limit guide block 302 and a side shaft 303. The cross arm 301 is snapped into the inside of the card slot 201 and both ends extend to the outside. There are two U-shaped limit guide blocks 302. The two U-shaped limit guide blocks 302 are respectively arranged at both outer ends of the cross arm 301. There are two side shafts 303. The two side shafts 303 are respectively arranged at the centers of both end faces of the cross arm 301. One end of the side shaft 303 away from the cross arm 301 is rotatably connected to the guide wheel 304. By providing the card slot 201, it is convenient to install the cross arm 301. By providing the U-shaped limit guide block 302, it can effectively ensure that when the cross arm 301 is snapped into the card slot 201, the snapping position of the cross arm 301 is accurate and the installation is convenient. By providing the guide wheel 304, it can effectively play a role in limiting and guiding the chemical fiber hair.

[0029] Among them; the driving and adjusting component 4 further includes a driving block 402, a mounting bracket 403 and a knob 404. The smooth end of the driving screw 401 passes through the column 2 and is fixedly connected to the knob 404. One end of the driving screw 401 away from the knob 404 is rotatably connected to the vertical plate of the mounting bracket 403. The end of the bottom plate of the mounting bracket 403 is fixedly connected to the column 2. The driving block 402 is threadedly connected to the driving screw 401. The lower end of the driving block 402 is slidably connected to the mounting bracket 403 through a slide bar. Side arms 405 are fixedly arranged on both sides of the driving block 402. By rotating the knob 404, the driving screw 401 can be effectively driven to rotate. Under the limiting action of the slide bar, the driving block 402 is realized to move back and forth along the driving screw 401. During the movement of the driving block 402, the tensioning component 5 can be driven to move synchronously through the side arms 405, so as to effectively adjust the tension of the chemical fiber hair.

[0030] Among them; the tensioning component 5 includes a fixing plate 501, a U-shaped frame 502 and a limiting slide bar 504. The fixing plate 501 is fixedly connected to the side arm 405. There are two limiting slide bars 504. The two limiting slide bars 504 are respectively fixedly arranged at both ends of the back of the U-shaped frame 502. One end of the two limiting slide bars 504 away from the U-shaped frame 502 passes through the fixing plate 501 and is provided with a limiting connecting plate 505. By providing the fixing plate 501, it is convenient to install the limiting slide bar 504 and the U-shaped frame 502, and the U-shaped frame 502 can be realized to move back and forth.

[0031] Among them; the limiting slide bar 504 is slidably connected to the fixing plate 501. A buffer spring 506 is sleeved on the outer surface of the limiting slide bar 504. One end of the buffer spring 506 is connected to the U-shaped frame 502, and the end of the buffer spring 506 away from the U-shaped frame 502 is connected to the fixing plate 501. A tensioning wheel 503 is rotatably arranged inside the U-shaped frame 502. When the forward movement distance of the tensioning component 5 is relatively large, at this time, the chemical fiber hair exerts a thrust on the tensioning wheel 503. The tensioning wheel 503 is forced to squeeze the buffer spring 506 and move toward the side close to the fixing plate 501, so as to buffer the acting force and avoid breaking of the chemical fiber hair.

[0032] Among them; fixing holes 101 are formed at both ends of the fixed base 1. By providing the fixed base 1 and the fixing holes 101, it is convenient to install and fix the hair tensioning device and ensure the overall stability.

[0033] Working principle: By providing the card slot 201, it is convenient to install the cross arm 301. By providing the U-shaped limiting guide block 302, it can effectively ensure that when the cross arm 301 is inserted into the card slot 201, the insertion position of the cross arm 301 is accurate and the installation is convenient. The chemical fiber hair moves upward from below the hair tensioning device, passes through the front of the tensioning wheel 503, then passes above the guide wheel 304, and is finally wound by the winding roller. By providing the guide wheel 304, it can effectively play a role in limiting and guiding the chemical fiber hair.

[0034] Furthermore, by rotating the knob 404, the driving screw 401 can be effectively driven to rotate. Under the limiting action of the slide bar, the driving block 402 can move back and forth along the driving screw 401. During the movement of the driving block 402, the tensioning assembly 5 can be driven to move synchronously through the side arm 405, effectively adjusting the tension of the chemical fiber hair. When the tensioning assembly 5 moves forward a large distance, at this time, the chemical fiber hair exerts a thrust on the tensioning wheel 503. The tensioning wheel 503 is stressed to squeeze the buffer spring 506 and move towards the side close to the fixing plate 501, thereby buffering the acting force and preventing the chemical fiber hair from breaking.
