[0002] The tension adjustment component of the spandex spinning machine plays a vital role in the spinning process. It ensures that the spandex yarn maintains appropriate tension during processing, thereby ensuring the quality of the yarn and spinning efficiency. If the tension adjustment work of the spinning is wrong, it may cause the yarn to be too loose and the spinning quality to be poor. If the yarn is too tight, it may cause the yarn to break.

[0034] A base 1, a support plate 2 is symmetrically fixed on the top of the base 1, and a guide roller assembly 3 for guiding the wire is installed on the support plate 2;

[0035] A positioning assembly is installed in the middle of the support plate 2 and is used to position the yarn between the support plates 2 to prevent the yarn from loosening and deviating when the spandex yarn is tensioned and adjusted;

[0036] The tensioning roller 4 is divided into two and is slidably mounted above and below the two ends of the support plate 2, and the two tensioning rollers 4 are located at diagonal positions of the support plate 2;

[0037] An adjustment component, installed on the inner wall of the base 1, used for electrically adjusting the distance between the two tensioning rollers 4;

[0038] The limiting assembly is installed on the adjusting assembly, moves with the tensioning roller 4 and can prevent the yarn on the tensioning roller 4 from being misaligned when being loose.

[0039] A slide box 5 is fixed to the side walls of the two support plates 2 close to the tensioning roller 4, and a moving block 6 is slidably connected to the inner wall of the slide box 5. The tensioning roller 4 is rotatably connected to the opposite side of the two moving blocks 6. An extension rod 7 is fixed under the two moving blocks 6, and the extension rod 7 is slidably connected to the slide box 5. A slider 8 is fixed between the two extension rods 7.

[0040] The adjustment component includes a double-headed motor 9 fixed to the inner wall of the base 1, the double-headed motor 9 is a reduction motor, the inner wall of the base 1 is symmetrically connected to the first screw 10 through a bearing, the output ends of the double-headed motor 9 are respectively fixed to the two first screws 10, the two sliders 8 are symmetrically threadedly connected to the outer walls of the two first screws 10, and the bottom of the slider 8 is slidably connected to the inner wall of the base 1.

[0041] This application provides an electrically controllable adjustment component so that the distance between the two tensioning rollers 4 can be electrically controlled. The steps for adjusting the tension of the spinning machine are simple, which saves manpower. The double-headed motor 9 adopts a reduction motor, which increases the accuracy of the adjustment.

[0042] Figures 4 to 6 A second embodiment is shown, and its main difference from the first embodiment is that the limiting assembly includes a bracket 11 fixed above two adjacent moving blocks 6, the inner wall of the bracket 11 is rotatably connected with a bidirectional screw 12, one end of the bidirectional screw 12 passes through the bracket 11 and is fixed with a turntable 13, the outer wall of the bidirectional screw 12 is symmetrically threadedly connected with a moving ring 14, the upper end of the moving ring 14 is slidably connected to the inner wall of the bracket 11, and the outer wall of the tensioning roller 4 is slidably connected to the inner walls of the two adjacent moving rings 14.

[0043] The positioning assembly includes a fixed plate 15 fixed between two support plates 2, an electric push rod 16 is fixed in the middle of the fixed plate 15, telescopic rods 17 are symmetrically fixed to the bottom of the fixed plate 15, a wire pressing block 18 is fixed to the output end of the electric push rod 16, and the protruding ends of the two telescopic rods 17 are fixed to the top of the wire pressing block 18. The support plate 2 is located below the wire pressing block 18 and is rotatably connected to a positioning roller 19.

[0044] This application sets a limit component so that the spacing of the movable ring 14 can be adjusted according to the width of the spandex spinning. When the yarn is loose, it can still be restricted to a fixed position on the tensioning roller 4, preventing the loose yarn from being displaced and tangled, which is practical.

[0045] Working principle:

[0046] The guide roller assembly 3 adopts the stabilizing roller in CN211112411U, which is the prior art and will not be described in detail.

[0047] The tension adjustment assembly is used in a spandex spinning machine room. The spandex yarn is introduced into the outer wall of the upper tension roller 4 by the guide roller assembly 3 above the support plate 2. The yarn passes around the upper tension roller 4 and goes around the upper end of the outer wall of the positioning roller 19.

[0048] The outer wall of the tensioning roller 4 wound around the lower end is led out by the guide roller assembly 3 below the support plate 2.

[0049] Rotating the turntable 13 to rotate the bidirectional screw 12 can drive the two movable rings 14 below the bracket 11 to move toward each other on the outer wall of the tension roller 4, limiting the spinning to the middle of the tension roller 4 to prevent the yarn from loosening and deviating.

[0050] When the yarn tension needs to be adjusted, the electric push rod 16 is extended to drive the telescopic rod 17 to extend, the wire pressing block 18 is pressed against the outer wall of the positioning roller 19, and the spinning is positioned between the support plates 2. According to the need of adjustment, the electric push rod 16 is driven to extend and retract to control the degree of contact between the spinning and the positioning roller 19, thereby controlling the tightness between the spinning and the positioning roller 19.

[0051] The double-headed motor 9 is started to drive the first screw 10 to rotate, so that the slider 8 moves toward each other on the inner wall of the base 1, thereby the extension rod 7 moves, driving the moving block 6 to move on the inner wall of the slide groove, and the tensioning roller 4 moves toward each other accordingly to adjust the tension of the spandex spinning.
