[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.
[0018] like Figures 1 to 4In the embodiment of the sweater yarn tensioning device of the utility model shown in the figure, the sweater yarn tensioning device comprises a support plate 1, a fixed column 2 is fixed at the bottom of the support plate 1, a first pulley 3 is rotatably connected to the fixed column 2, a support 4 is fixed to the bottom of the support plate 1, a groove is provided on the support 4, a slide seat 5 is slidably connected in the groove, a roller 6 which can cooperate with the first pulley 3 is rotatably connected on the slide seat 5, and the top of the roller 6 can contact the inner side of the first pulley 3. Two slide grooves are provided at the top of the support plate 1, a slider 7 is slidably connected in the slide groove, and the two sliders 7 can move relative to or away from each other, and a second pulley 8 is rotatably connected to the slider 7. The two second pulleys 8 are respectively located on the left and right sides above the first pulley 3, and a clamping seat 9 is provided on one side of one of the second pulleys 8. The clamping seat 9 is fixedly connected to the support plate 1, a cross groove is provided on the clamping seat 9, and an L-shaped rod 10 is slidably connected to the clamping seat 9, and one side of the L-shaped rod 10 can extend into the cross groove. The yarn is then passed through the cross groove on the holder 9 and connected to the winding structure. When the tightness of the yarn needs to be adjusted, the two second pulleys 8 can be moved relative to or away from each other, and the top of the roller 6 can be in contact with the inner side of the first pulley 3 so that the yarn is located between the roller 6 and the first pulley 3. The roller 6 can provide a squeezing force so that the yarn can be in a taut state when the winding structure is winding. After the yarn winding is completed, the yarn is clamped in the cross groove by moving the L-shaped rod 10, and the yarn on one side of the holder 9 is cut off, which can prevent the yarn from escaping from the device. When a new reel is installed, the clamping of the yarn by the L-shaped rod 10 can be released, and the joint of the yarn can be pulled to connect with the reel of the winding structure.
[0019] In an embodiment of the present application, preferably, a through groove is connected between the two sliding grooves, and two studs 11 are arranged in the through groove, and the two studs 11 are respectively threadedly connected to the corresponding sliding blocks 7.
[0020] In one embodiment of the present application, preferably, a rotating wheel 12 is rotatably connected to the middle portion of the support plate 1, and the opposite ends of the two studs 11 are fixedly connected to the two sides of the rotating wheel 12 respectively. The threads on the two studs 11 have opposite rotation directions. By rotating the rotating wheel 12, the two studs 11 can be rotated, thereby driving the two second pulleys 8 to move relative to or away from each other.
[0021] In one embodiment of the present application, preferably, a first bolt 13 is threadedly connected to the upper side of the support plate 1, and the bottom of the first bolt 13 can contact the surface of the rotating wheel 12. By rotating the first bolt 13, the bottom of the first bolt 13 can be pressed against the rotating wheel 12, thereby avoiding the position of the adjusted second pulley 8 from being offset.
[0022] In one embodiment of the present application, preferably, a rectangular block 14 is slidably connected in the groove, the upper side of the rectangular block 14 is connected to the bottom of the slide seat 5 via a spring, and the roller 6 can apply pressure to the first pulley 3 under the action of the spring.
[0023] In one embodiment of the present application, preferably, the bottom of the support 4 is threadedly connected with a second bolt 15, and the top of the second bolt 15 is rotatably connected to the rectangular block 14, and the force applied by the spring can be adjusted by rotating the second bolt 15.
[0024] When the utility model is in use, one end of the spun yarn is passed around one of the second pulleys 8 and then around the bottom of the first pulley 3, and then around the other second pulley 8, and the yarn is passed through the cross groove on the holder 9 and connected to the winding structure. When the tightness of the yarn needs to be adjusted, the rotating wheel 12 is rotated to rotate the two studs 11, driving the two second pulleys 8 to move relative to or away from each other, so that the yarn can be tightened or loosened, and the top of the roller 6 can be in contact with the inner side of the first pulley 3, so that the yarn can be tightened or loosened. The yarn is located between the roller 6 and the first pulley 3. The roller 6 can apply pressure to the first pulley 3 under the action of the spring, so that the yarn can be in a taut state when the winding structure is winding. After the yarn is wound, the yarn is clamped in the cross groove by moving the L-shaped rod 10, and the yarn on one side of the holder 9 is cut off, which can avoid causing the yarn to escape from the device. When a new reel is installed, the L-shaped rod 10 can release the clamping of the yarn, and the joint of the yarn can be pulled to connect with the reel of the winding structure.
