A plurality of T-shaped sliders 106 are slidably connected in the plurality of T-shaped sliding slots 105. The T-shaped sliders 106 are matched with the T-shaped sliding slots 105. A traction ring 107 is fixedly installed at the top of each of the plurality of T-shaped sliders 106. One side of the bottom end of each of the plurality of T-shaped sliders 106 is rotatably connected to a connecting column 108. One end of each of the plurality of connecting columns 108 extends into the corresponding movable slot 104. The connecting column 108 is matched with the movable slot 104. A first connecting plate 109 is fixedly installed on one side of the second turntable 102. A second connecting plate 110 is fixedly installed on one side of the first turntable 101. A movable block 111 is rotatably connected to both the first connecting plate 109 and the second connecting plate 110. A driving motor 112 is fixedly installed on one side of the movable block 111. The input end of the driving motor 112 is connected to a power supply through an external cable.

[0030] Embodiment 2

[0031] As Figures 1 to 5As shown in the figure, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that the traction assembly 200 includes a bump 201 fixedly installed on one side of the bottom of the mounting plate 5. A driving motor 202 is fixedly installed on one side of the bottom of the mounting plate 5. The input end of the driving motor 202 is connected to a power source through an external cable. The output end of the driving motor 202 passes through a bearing to the side of the bump 201 and is fixedly installed with a first traction wheel 203. A limiting chute 204 is provided on one side of the bump 201. A clamping block 205 is slidably connected in the limiting chute 204. The clamping block 205 matches the limiting chute 204. A second traction wheel 206 is rotatably connected to one side of the clamping block 205. The first traction wheel 203 and the second traction wheel 206 are on the same horizontal plane. A second threaded rod 207 is rotatably connected to one side of the clamping block 205. One end of the second threaded rod 207 is threadedly penetrated to the side of the bump 201 and is fixedly installed with a rotating handle 208. Through the provided traction assembly 200, the traction adjustment of cotton strips with different widths can be effectively carried out. When it is necessary to carry out traction adjustment on cotton strips with different widths, by rotating the rotating handle 208 to drive the second threaded rod 207 to rotate, the second threaded rod 207 pushes the second traction wheel 206 on one side of the clamping block 205 close to the first traction wheel 203, so as to carry out traction on cotton strips with different widths.

[0032] During operation, the staff first passes the cotton strip at the output end of the drawframe body 1 through a number of traction rings 107 in an S shape in sequence, and then rotates the rotating handle 208 according to the width of the cotton strip to drive the second threaded rod 207 to rotate. The second threaded rod 207 pushes the second traction wheel 206 on one side of the clamping block 205 close to the first traction wheel 203. Then, the driving motor 202 is started to traction the cotton strip. Since the cotton strip passes through a number of traction rings 107 in sequence, the cotton strip is stretched. When it is necessary to adjust the stretching degree of the cotton strip, by starting the driving motor 112 to drive the first threaded rod 113 to rotate, during the rotation of the first threaded rod 113, one end of the first threaded rod 113 away from the driving motor 112 is threadedly penetrated to the side of another movable block 111, so as to drive the second turntable 102 to rotate. While the second turntable 102 is rotating, through the mutual cooperation among the extension plate 103, the movable groove 104, the T-shaped chute 105, the T-shaped slider 106, the second connecting plate 110, and the connecting column 108, a number of traction rings 107 are driven to move relatively, so as to adjust the stretching degree of a number of traction rings 107 on the cotton strip according to the actual situation of the cotton strip, with strong flexibility.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
