And 4, step 4: as shown in fig. 6, the push rod 51 is retracted, and the traverse 41 approaches the winding head 31A as soon as the glass strand enters the winding head 31A, and the normal arrangement of the yarn package is started.

And 5: as shown in fig. 7, the winding head 31A and the winding head 32A are full of yarn packages, the yarn arranging device 41 is far away from the winding head 31A, the yarn pushing rod 51 is pushed out, and the glass fiber bundles are wound in the yarn storage groove at the front end of the winding head 31A.

Step 6: as shown in FIG. 8, the wire arranging device 42 is far away from the winding head 32A, the wire pushing rod 52 is pushed out, and the second glass fiber bundle is wound in the outer wire storage groove at the front end of the winding head 32A.

And 7: as shown in fig. 9, the rotary reversing system 8 starts to rotate clockwise, and when a certain angle is reached, the first glass fiber bundle is cut off by the fiber storage groove in the front end of the winding head 32A and is wound.

And 8: as shown in FIG. 10, the rotary direction changing system 8 continues to rotate clockwise, and the glass filament bundle is cut and wound by the filament storage groove at the front end of the winding head 31B.

Wherein, the glass strand in step 7 is once connected from the winding head 31A by the winding head 32A, and the glass strand in step 8 is once connected from the winding head 32A by the winding head 31B, and the glass strand completes the switching of a group of winding heads under the continuous traction condition.

And step 9: as shown in figure 11, the rotary reversing system 8 continues to rotate clockwise, and the second glass fiber bundle is cut off and wound by the outer fiber storage groove at the front end of the winding head 32B.

Step 10: as shown in fig. 12, the rotary reversing system 8 rotates counterclockwise to return to the running position, and at this time, the rotary reversing system 8 rotates 180 ° based on the state shown in fig. 3, the winding head 31B and the winding head 32B reach the running position, and the winding head 31A and the winding head 32A reach the standby position.

When the direction-changing system 8 continues to rotate clockwise to 180 degrees in step 9, the winding head 32B cannot reach the second glass strand and must rotate more than 180 degrees, and after the rewinding head 32B successfully receives the second glass strand, the rewinding head needs to rotate counterclockwise (counterclockwise rotation in step 9) to return to the 180-degree position.

Step 11: as shown in fig. 13, the pushing rod 52 is retracted, the second glass fiber bundle enters the winding head 32B, the wire arranging device 42 approaches the winding head 32B, and the normal arrangement of the yarn package is started.

Step 12: as shown in fig. 14, the push rod 51 is retracted, and the traverse 41 approaches the winding head 31B as soon as the glass strand enters the inside of the winding head 31B, and the normal arrangement of the yarn package is started.

Step 13: as shown in fig. 15, the auxiliary bobbin discharging mechanism 61 and the auxiliary bobbin discharging mechanism 62 sequentially push out the full-package yarns on the standby winding head 31A and the winding head 32A, respectively. The state of the drawing machine returns to the state of step 4.

Step 14: and after the winding head is operated to be fully wound, repeating the actions of the steps 5 to 13, and repeating the steps.

In an optional embodiment, the winding heads 3 can be set into three groups, each group of the winding heads 3 comprises two winding heads 3, each group of the two winding heads is symmetrically arranged at 180 degrees, the three groups of six winding heads 3 are arranged at intervals of 60 degrees, the three adjacent winding heads 3 in the three groups work simultaneously, the division number is doubled and increased, the production efficiency is further greatly improved, the production cost is reduced, and the working process of the drawing machine is similar to that of the drawing machine with the two groups of winding heads in the embodiment and is not described redundantly.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
