[0025] The following further describes the present utility model with reference to the drawings:

[0026] As Figures 1 - 5 shown, a bobbin changing mechanism of a drawing frame includes a mounting mechanism 1 and further includes a bobbin changing mechanism 2 for replacing a yarn bobbin 210, and the bobbin changing mechanism 2 is fixed on the mounting mechanism 1.

[0027] In the present utility model, the installation mechanism 1 includes an installation block 101 and a first arc-shaped rod 102. The first arc-shaped rod 102 is fixed on the installation block 101. The installation block 101 is made of stainless steel, and the first arc-shaped rod 102 is welded to the installation block 101. After the device is placed at the corresponding position, bolts are used to fix the installation block 101, so as to avoid displacement of the device.

[0028] In the present utility model, the bobbin-changing mechanism 2 includes a chassis 201, a motor 202, a driving gear 203, a driven gear 204, a rotating rod 205, a rotating plate 206, a connecting rod 207, a second arc-shaped rod 208, a rolling body 209, and a yarn bobbin 210. The motor 202 is fixed above the chassis 201, the driving gear 203 is fixed to the output end of the motor 202, the driven gear 204 is engaged on the side of the driving gear 203, the rotating rod 205 is fixed inside the driven gear 204, the rotating plate 206 is fixed above the rotating rod 205, the connecting rod 207 is installed on the rotating plate 206, the second arc-shaped rod 208 is installed at the end of the connecting rod 207 away from the rotating plate 206, the rolling body 209 is installed on the second arc-shaped rod 208, and the yarn bobbin 210 is arranged on the chassis 201. The motor 202 and the chassis 201 are connected by bolts. The rolling body 209 is made of alloy steel. When using the device, the yarn bobbin 210 is placed at the initial position, the motor 202 is started, the operation of the motor 202 drives the driving gear 203 to rotate, the rotation of the driving gear 203 drives the driven gear 204 to rotate, the rotating rod 205 and the rotating plate 206 rotate accordingly, the rotation of the rotating plate 206 drives the yarn bobbin 210 to rotate. When the rotating plate 206 rotates 180 degrees, the motor 202 stops running. At this time, the yarn bobbin 210 rotates to the working position, and the yarn bobbin 210 rotates to wind the yarn processed by the drawing frame. At this time, the staff can place another yarn bobbin 210 at the initial position. After the yarn winding is completed, the motor 202 is started again. The yarn bobbin 210 wound with yarn and the new yarn bobbin 210 rotate synchronously. When the new yarn bobbin 210 rotates to the working position, the motor 202 stops running. At this time, the yarn bobbin 210 wound with yarn rotates to the initial position. The yarn bobbin 210 wound with yarn is removed and a new yarn bobbin 210 is replaced. In this way, continuous winding of the yarn can be achieved by cycling. By adopting the above method, rapid replacement of the yarn bobbin 210 can be realized, and the working efficiency is effectively improved.

[0029] In the present utility model, a protection mechanism 3 is installed on the bobbin changing mechanism 2.

[0030] In the above structure: When using the device, after placing the device in the corresponding position, use bolts to fix the mounting block 101. After the device is installed, place the yarn bobbin 210 in the initial position, start the motor 202. The operation of the motor 202 drives the driving gear 203 to rotate, the rotation of the driving gear 203 drives the driven gear 204 to rotate, and the rotating rod 205 and the rotating plate 206 rotate accordingly. The rotation of the rotating plate 206 drives the yarn bobbin 210 to rotate. When the rotating plate 206 rotates 180 degrees, the motor 202 stops running. At this time, the yarn bobbin 210 rotates to the working position, and the yarn bobbin 210 rotates to wind the yarn processed by the drawframe. At this time, the staff can place another yarn bobbin 210 in the initial position. After the yarn winding is completed, start the motor 202 again. The yarn bobbin 210 wound with yarn and the new yarn bobbin 210 rotate synchronously. When the new yarn bobbin 210 rotates to the working position, the motor 202 stops running. At this time, the yarn bobbin 210 wound with yarn rotates to the initial position. Remove the yarn bobbin 210 wound with yarn and replace it with a new yarn bobbin 210. In this way, continuous winding of the yarn can be achieved by cycling.
