The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a winding device for polypropylene yarn production, comprising a bottom plate 1 and an upper plate 2 arranged above the bottom plate 1, a winding roller 3 is installed between the bottom plate 1 and the upper plate 2, a connecting rod 4 is fixedly installed at the end of the upper plate 2, a fixing rod 5 is fixedly installed at the end of the bottom plate 1, a servo motor 21 is fixedly installed at the upper end of the upper plate 2, an output shaft of the servo motor 21 is fixedly connected to a hexagonal rod 22, a fixing rod 5 is fixedly installed at the end of the bottom plate 1, a threaded rod 7 is rotatably installed on the fixing rod 5, a connecting block 41 is fixedly installed at the end of the connecting rod 4, the threaded rod 7 passes through the connecting block 41 and is threadedly connected to the connecting block 41, and the winding roller 3 is installed between the bottom plate 1 and the upper plate 2, and the connecting rod 4 is fixedly installed at the end of the upper plate 2.

A hexagonal groove 32 is provided on the upper surface of the rotating shaft 31 on the upper side. The hexagonal rod 22 is movably inserted into the hexagonal groove 32. A circular hole 23 is provided in the middle of the upper plate 2. The hexagonal rod 22 movably passes through the circular hole 23. A circular groove 11 is provided in the middle of the bottom plate 1. Two rotating shafts 31 are respectively arranged in the circular groove 11 and the circular hole 23. Balls 6 are equidistantly arranged on the circumference of the upper end of the bottom plate 1 and the bottom end of the upper plate 2. The servo motor 21 is started to rotate the hexagonal rod 22, and the winding roller 3 is driven to rotate by the rotation of the hexagonal rod 22. The polypropylene yarn can be automatically wound on the winding roller 3 by the rotation of the winding roller 3. On the winding roller 3, after winding is completed, the staff rotates the turntable 8 to rotate the connecting shaft, and the bevel gear 2 81 rotates through the rotation of the connecting shaft. Since the bevel gear 2 81 is meshed with the bevel gear 1 71, the threaded rod 7 rotates, and the rotation of the threaded rod 7 drives the connecting rod 4 to move upward, and the upward movement of the connecting rod 4 drives the upper plate 2 to move upward, and the upward movement of the upper plate 2 drives the servo motor 21 to move upward, and the upward movement of the servo motor 21 drives the hexagonal rod 22 to move upward, so that the hexagonal rod 22 disengages from the hexagonal groove 32. At this time, the upper plate 2 and the hexagonal rod 22 no longer limit the winding roller 3 and the hexagonal groove 32, and the staff The winding roller 3 can be removed from between the bottom plate 1 and the upper plate 2. When the winding roller 3 needs to be installed, the rotating shaft 31 at the bottom of the winding roller 3 is inserted into the circular groove 11, and the turntable 8 is twisted in the opposite direction to reverse the threaded rod 7, so that the upper plate 2 moves down, so that the gap between the upper plate 2 and the bottom plate 1 is reduced, and the winding roller 3 is installed and limited. The upper plate 2 moves down so that the hexagonal rod 22 is inserted into the hexagonal groove 32, and the servo motor 21 is started to drive the winding roller 3 to rotate. The device is convenient for installing and disassembling the winding roller 3, and it is convenient to replace the winding roller 3, which is beneficial to the subsequent continuous winding operation of the polypropylene yarn and is more convenient to use.

[0024] The bottom end of the connecting rod 4 is fixedly installed with a guide slide bar 42, and a limiting groove 51 is provided on the upper surface of the fixing rod 5, and the guide slide bar 42 is movably inserted into the limiting groove 51, and a bevel gear 1 71 is fixedly installed on the threaded rod 7, and a turntable 8 is provided on the fixing rod 5. A connecting shaft is fixedly installed in the middle of the turntable 8, and the connecting shaft is rotatably installed on the fixing rod 5, and a bevel gear 2 81 is fixedly installed on the connecting shaft, and the bevel gear 1 71 is meshed with the bevel gear 2 81. Balls 6 are provided on both the bottom plate 1 and the upper plate 2 to reduce the friction between the top and bottom of the winding roller 3 and the upper plate 2 and the bottom plate 1, and the guide slide bar 42 is movably inserted into the limiting groove 51, which limits the movement of the upper plate 2 and the connecting rod 4, and prevents the threaded rod 7 from driving the upper plate 2 and the connecting rod 4 to rotate together when rotating, so that the movement of the upper plate 2 and the connecting rod 4 is more stable, and the rationality of the structural design is guaranteed. By providing a turntable 8, it is convenient to drive the threaded rod 7 to rotate, and the operation is more convenient.

[0025] Working principle:

[0026] The first step is to start the servo motor 21 to rotate the hexagonal rod 22, and the rotation of the hexagonal rod 22 drives the winding roller 3 to rotate. The rotation of the winding roller 3 can automatically wind the polypropylene yarn on the winding roller 3. After the winding is completed, the staff rotates the turntable 8 to rotate the connecting shaft, and the bevel gear 2 81 rotates through the rotation of the connecting shaft. Since the bevel gear 2 81 is engaged with the bevel gear 1 71, the threaded rod 7 rotates, and the rotation of the threaded rod 7 drives the connecting rod 4 to move upward, and the upward movement of the connecting rod 4 drives the upper plate 2 to move upward, and the upward movement of the upper plate 2 drives the servo motor 21 to move upward, and the upward movement of the servo motor 21 drives the hexagonal rod 22 to move upward, so that the hexagonal rod 22 is disengaged from the hexagonal groove 32. At this time, the upper plate 2 and the hexagonal rod 22 are disengaged from the hexagonal groove 32. The rectangular rod 22 no longer limits the winding roller 3 and the hexagonal groove 32, so the staff can remove the winding roller 3 from between the bottom plate 1 and the upper plate 2. When the winding roller 3 needs to be installed, the rotating shaft 31 at the bottom of the winding roller 3 is inserted into the circular groove 11, and the turntable 8 is twisted in the opposite direction to reverse the threaded rod 7, so that the upper plate 2 moves downward, and the gap between the upper plate 2 and the bottom plate 1 is reduced, and the winding roller 3 is limited for installation. By moving the upper plate 2 downward, the hexagonal rod 22 is inserted into the hexagonal groove 32, and the servo motor 21 is started to drive the winding roller 3 to rotate. The device is convenient for the installation and disassembly of the winding roller 3, and it is convenient to replace the winding roller 3, which is beneficial to the subsequent continuous winding operation of the polypropylene yarn and is more convenient to use.

[0027] In the second step, ball bearings 6 are arranged on both the bottom plate 1 and the upper plate 2 to reduce the friction between the top and bottom of the winding roller 3 and the upper plate 2 and the bottom plate 1. The guide slide rod 42 is movably inserted into the limit groove 51 to limit the movement of the upper plate 2 and the connecting rod 4, preventing the threaded rod 7 from driving the upper plate 2 and the connecting rod 4 to rotate together during rotation, making the movement of the upper plate 2 and the connecting rod 4 more stable and ensuring the rationality of the structural design. By providing a turntable 8, it is convenient to drive the threaded rod 7 to rotate, and the operation is more convenient.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
