[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figures 1-4 A rewinding device for facilitating the lateral unwinding of a winding machine drum includes a rewinding mechanism 1. The rewinding mechanism 1 includes a base 101, and support plates 102 are symmetrically fixedly connected to the top of the base 101. The base 101 is configured to provide support for the support plates 102. Reinforcing ribs 103 are symmetrically fixedly connected to the opposite sides of both sets of support plates 102. Each set of reinforcing ribs 103 is fixedly connected to the base 101. The reinforcing ribs 103 are configured to further connect and fix the support plates 102 to the base 101, thereby improving the connection stability between the support plates 102 and the base 101.

[0024] Both sets of support plates 102 have grooves 104 on their tops, and a rotating shaft 105 is placed inside each groove 104. The grooves 104 are designed to accommodate and limit the rotation of the rotating shaft 105. Multiple first balls 107 are movably connected in a circular array inside each groove 104. The first balls 107 reduce friction during rotation of the rotating shaft 105, thus making its rotation smoother. Symmetrically, ball grooves 108 are formed on the outer side of the rotating shaft 105, corresponding to the first balls 107 on both sides. The ball grooves 108 accommodate the first balls 107, allowing them to roll within them, while also limiting the rotation of the shaft 105 to reduce the probability of lateral movement.

[0025] A spinning spindle 106 is fixedly connected to the outer side of the rotating shaft 105. The outer side of the spinning spindle 106 is used to fit a yarn bobbin, so that the yarn can be unwound laterally. A limiting mechanism 2 includes a fixed limiting ring 201 fixedly connected to one side of the spinning spindle 106, which limits one end of the yarn bobbin. A limiting groove 204 is formed on the other side of the spinning spindle 106, and a movable limiting ring 202 is fitted onto the outer side of the spinning spindle 106. The movable limiting ring 202 limits the other end of the yarn bobbin fitted onto the outer side of the spinning spindle 106, reducing the probability of the yarn bobbin shifting during use.

[0026] The inner wall of the movable limiting ring 202 is fixedly connected with multiple limiting blocks 205 in a ring array. Each set of limiting blocks 205 is adapted to a set of limiting grooves 204. The limiting grooves 204 are set to guide and limit the sliding of the limiting blocks 205, thereby limiting the movable limiting ring 202. A connecting shaft 206 is rotatably connected to one side of the inner side of each of the two sets of support plates 102. A U-shaped plate 207 corresponding to the groove 104 is rotatably connected to the outer side of each of the two sets of connecting shafts 206. The connecting shafts 206 are set to drive the U-shaped plates 207 to rotate with them when rotating, so that when the U-shaped plates 207 rotate into the inner side of the groove 104, they can limit the rotating shaft 105.

[0027] A torsion spring 216 is fixedly connected between the support plate 102 and the U-shaped plate 207. The torsion spring 216 can use its elasticity to drive the U-shaped plate 207 to rotate into the groove 104, thereby reducing the probability of the rotating shaft 105 disengaging from the groove 104. A fixing block 209 is fixedly connected to the top of a set of U-shaped plates 207. A first screw 210 is threadedly connected to the inside of the fixing block 209. A first stop 211 is fixedly connected to the side of the first screw 210 near the moving limit ring 202. The first screw 210 is used to drive the first stop 211 to move when rotating, thereby adjusting the distance between the first stop 211 and the moving limit ring 202. A third ball bearing 212 is movably connected to one end of the first stop block 211 near the moving limit ring 202. The third ball bearing 212 is in contact with the moving limit ring 202. The third ball bearing 212 is set to move synchronously with the first stop block 211. When the third ball bearing 212 is in contact with the moving limit ring 202, it can limit the movement of the moving limit ring 202.

[0028] A second screw 213 is internally threaded onto one side of the support plate 102. A second stop 214 is fixedly connected to the end of the second screw 213 near the moving limit ring 202. The second screw 213 is configured to move the second stop 214 toward one side of the moving limit ring 202 when rotated. A fourth ball bearing 215 is movably connected to the end of the second stop 214 away from the second screw 213. The fourth ball bearing 215 contacts the moving limit ring 202, and its placement further limits the movement of the moving limit ring 202. The movable limiting ring 202 has an integral inclined surface 203 on the side near the first stop block 211. The inclined surface 203 is designed so that the fourth ball bearing 215 can roll along the inclined surface 203 during the process of the rotating shaft 105 being placed inside the groove 104, thereby pushing the movable limiting ring 202 to one side of the fixed limiting ring 201, so that the limiting block 205 can slide to abut against the side wall of the limiting groove 204 near the fixed limiting ring 201. The bottom of both sets of U-shaped plates 207 are movably connected with second balls 208 that are adapted to the ball groove 108. The second balls 208 are designed to reduce the friction between the rotating shaft 105 and the U-shaped plate 207.

[0029] In use, flip the U-shaped plates 207 on both sides to a vertical position to stop limiting the rotating shaft 105. Then, remove the rotating shaft 105 from the inside of the two sets of grooves 104. Next, remove the movable limiting ring 202 from the outside of the spinning spindle 106, and put the yarn bobbin on the outside of the spinning spindle 106. Then, put the movable limiting ring 202 on the outside of the spinning spindle 106, and let each set of limiting blocks 205 slide into the inside of each set of limiting grooves 204. Then, put the two sides of the rotating shaft 105 into the inside of the two side grooves 104, so that the first ball bearings 107 on both sides are respectively placed in the ball bearing grooves on both sides. Inside 108, the U-shaped plate 207 is then released, causing the torsion springs 216 on both sides to return to their original deformation. This causes the U-shaped plate 207 to rotate into the groove 104 until the second ball 208 rotates into the ball groove 108, thus limiting the rotation shaft 105. When the U-shaped plate 207 rotates, it can drive the fixed block 209, the first stop block 211, and the third ball 212 to rotate as well. This causes the third ball 212 to rotate until it contacts the moving limit ring 202, thereby limiting the moving limit ring 202 and reducing the probability of the moving limit ring 202 moving during the rewinding process.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
