[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figures 1-3 , an automatic winding device for PP strapping production includes a connecting platform 1. Two support frames 2 are symmetrically installed at the lower end of the connecting platform 1. The support frames 2 can stably support the connecting platform 1. A rectangular strip 3 is fixedly connected to the upper end of the connecting platform 1. A chute 4 is opened on the right side of the rectangular strip 3;

[0020] Among them, there are also two limiting disks 9, the two limiting disks 9 are arranged oppositely, and a plurality of annular grooves 10 are opened on the opposite sides of the two limiting disks 9. A plurality of limiting pins 11 are installed in each annular groove 10. The use of the limiting pins 11 can increase the firmness after limiting;

[0021] Among them, there is also a moving mechanism, which is used to move the upper limiting disk 9 up and down. The moving mechanism includes a threaded rod 5 rotatably connected between the upper and lower inner walls of the sliding groove 4. A slider 7 is threadedly connected to the threaded rod 5. The slider 7 is slidably connected to the inner wall of the sliding groove 4. The right side of the slider 7 penetrates through the notch of the sliding groove 4 and is fixedly connected to a connecting plate 8. The lower end of the connecting plate 8 is rotatably connected to a rotating shaft 13 through a bearing. The lower end of the rotating shaft 13 is fixedly connected to the upper end of the upper limiting disk 9. A first motor 6 is installed at the upper end of the rectangular strip 3. The output shaft of the first motor 6 extends into the sliding groove 4 and is fixedly connected to the upper end of the threaded rod 5. The first motor 6 is a servo motor that can change the rotation direction;

[0022] Among them, there is also a rotating mechanism, which is used to drive the lower limiting disk 9 to rotate. The rotating mechanism includes a second motor 12 fixedly connected to the lower end of the connecting platform 1. The output shaft of the second motor 12 penetrates through the connecting platform 1 and is fixedly connected to the lower end of the lower limiting disk 9. It should be noted that a moving guiding structure is also provided on the front side of the device for evenly packing the packing belt on the paper tube. This structure is a prior art and will not be specifically described here.

[0023] In the present utility model, during use, the hard paper tube to be used is placed into the corresponding annular groove 10 according to the radius. By using the setting of the annular groove 10, precise positioning can be achieved, ensuring that the central axis of the hard paper tube coincides with the central axis of the output shaft of the second motor 12;

[0024] Then start the first motor 6, which can drive the threaded rod 5 to rotate. The rotation of the threaded rod 5 will drive the slider 7 to move downward, and then through the connecting plate 8 and the rotating shaft 13, the upper limiting disk 9 will move downward, so that the corresponding annular groove 10 is stuck into the upper edge of the hard paper tube. By using the limiting pins 11, the hard paper tube can be more firmly limited. Then heat one end of the packing belt and attach it to the side wall of the hard paper tube. After cooling and connection, start the second motor 12 to perform the winding operation.
