The bobbin clamping device is connected to the rotating motor. The bobbin clamping device includes a support frame with a hollow and rectangular structure. An inner support top plate is arranged on the side support plate, and a push-pull structure is arranged inside the support frame. The beneficial effect of the utility model is that the bobbin is sleeved on the support frame, and then by pulling the push-pull column, the inner support top plate is driven by the push-pull column to rotate along the rotating rod seat, and the inner support plate is propped against the inner side of the bobbin, so as to fix the bobbin. Then, the whole device is driven by the rotating motor to rotate to achieve the purpose of winding. This patent uses a pure mechanical structure to replace the traditional method of installing multiple motors and manipulators on the winding machine, solving the problem of high cost of the traditional winding machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0020] As Figures 1-4 shown, a bobbin clamping device for a winding machine includes a bottom shell 1, and a plurality of driving mechanisms 3 are arranged inside the bottom shell 1, and a clamping mechanism 2 is arranged above the driving mechanism 3.

[0021] In this embodiment, the clamping mechanism 2 includes a secondary rod 201, a sleeve 202, a plurality of connecting rods 203, a plurality of clamping plates 204, a plurality of auxiliary rods 205 and a threaded rod 206. The lower end of the threaded rod 206 is rotatably connected to the middle of the sleeve 202, the outer periphery of the lower part of the secondary rod 201 is slidably connected to the inner side of the upper part of the sleeve 202, the outer periphery of the threaded rod 206 is threadedly connected to the middle of the secondary rod 201, one end of a plurality of connecting rods 203 is rotatably connected to the outer periphery of the upper part of the secondary rod 201, the upper end of the clamping plate 204 is rotatably connected to the other end of the connecting rod 203, one end of the auxiliary rod 205 is rotatably connected to the outer periphery of the sleeve 202, the other end of the auxiliary rod 205 is rotatably connected to the middle and lower part of the clamping plate 204, the lower end of the clamping plate 204 is rotatably connected to one end of a balance rod 210, the other end of the balance rod 210 is rotatably connected to the outer periphery of the sleeve 202, the auxiliary rod 205 and the balance rod 210 are parallel to each other, a limiting plate 207 is arranged at the lower part of the secondary rod 201, the outer periphery of the limiting plate 207 is slidably connected to the inner side of the upper side of the sleeve 202, the upper end of the threaded rod 206 is fixedly connected with a knob 208, and a rubber pad 209 is arranged on the side of the clamping plate 204 away from the threaded rod 206.

[0022] Specifically, through the parallel auxiliary rod 205 and balance rod 210, the clamping plate 204 is always kept in a vertical state. The bobbin is sleeved on the outer periphery of the clamping mechanism 2, and then the knob 208 is rotated, so that the threaded rod 206 rotates. Since the secondary rod 201 cannot rotate relative to the sleeve 202, the secondary rod 201 will move towards the sleeve 202, and the clamping plate 204 is expanded outward through the connecting rod 203 and the auxiliary rod 205, so as to fixedly clamp bobbins of different diameters.

[0023] In this embodiment, the driving mechanism 3 includes a servo motor 301, a connecting seat 302, a plurality of magnets one 303, a plurality of magnets two 304 and a shaft seat 305. The lower end of the shaft seat 305 is fixedly connected to the upper part of the bottom shell 1, the outer periphery of the lower part of the sleeve 202 is rotatably connected to the inside of the shaft seat 305, a plurality of magnets two 304 are installed on the lower part of the sleeve 202, the outer periphery of the connecting seat 302 is rotatably connected to the upper part of the bottom shell 1, a plurality of magnets one 303 are installed on the upper part of the connecting seat 302, the servo motor 301 is installed on the inner bottom wall of the bottom shell 1, the upper output end of the servo motor 301 is fixedly connected to the middle of the connecting seat 302, and the magnets one 303 and the magnets two 304 are in one-to-one correspondence.

[0024] Specifically, through the mutual attraction between magnet one 303 and magnet two 304, the servo motor 301 can drive the clamping mechanism 2 to rotate, so that the bobbin can rotate. When the yarn is stuck, the bobbin will not rotate, which can prevent the yarn from breaking.

[0025] Working principle:

[0026] Through the mutual attraction between magnet one 303 and magnet two 304, the servo motor 301 can drive the clamping mechanism 2 to rotate, so that the bobbin can rotate. When the yarn is stuck, the bobbin will not rotate, which can prevent the yarn from breaking. Through the parallel auxiliary rod 205 and balance rod 210, the clamping plate 204 can always be kept vertical. The bobbin is sleeved on the outer periphery of the clamping mechanism 2, and then the knob 208 is turned to make the threaded rod 206 rotate. Since the auxiliary rod 201 cannot rotate relative to the sleeve 202, the auxiliary rod 201 will move towards the sleeve 202. Through the connecting rod 203 and the auxiliary rod 205, the clamping plate 204 expands outwards, so as to fixedly clamp bobbins of different diameters.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
