[0025] Two mobile racks 4;

[0026] Centering mechanism, two mobile racks 4 are installed on the bracket 1 through the centering mechanism, and the two mobile racks 4 are linearly moved synchronously and in opposite directions through the centering mechanism. The spacing between the two mobile racks 4 is adjusted by controlling the centering mechanism, so as to adapt to cloth rollers of different lengths;

The two ends of the guide rods 3 are respectively fixed on the two ends of the bracket 1, and the movable frame 4 is slidably mounted on each guide rod 3. It can be seen that the movable frame 4 moves linearly through the guide structure.

[0029] Specifically, the centering mechanism also includes a double-threaded rod 22 and a worm reducer motor 2. A first rotating hole is provided at both ends of the bracket 1. The two ends of the double-threaded rod 22 are respectively rotatably installed in the two first rotating holes.

The casing of the worm reducer motor 2 is fixed on the bracket 1, and the output shaft of the worm reducer motor 2 is coaxially fixed with the double-threaded rod 22. It can be seen that the worm reducer motor 2 causes the double-threaded rod 22 to rotate axially through the output shaft, and the two ends of the double-threaded rod 22 cause the two movable frames 4 to move linearly along the guide rod 3 through threads, and the two movable frames 4 move in opposite directions.

[0030] Specifically, the pushing mechanism includes a bevel gear ring 11, a plurality of concave frames 16, a plurality of first fixed plates 12, a plurality of second fixed plates 15, a plurality of spline columns 14, a plurality of external threaded sleeves 13, a plurality of internal threaded sleeves 21 and a plurality of driven bevel gears 23.

It can be seen that the two rotating rods 10 rotate synchronously through the spline shaft 7 and the spline sleeve 8.

[0033] Specifically, a handle 5 is fixed to one end of the transmission rod.

[0034] Working principle: The cloth winding roller is placed between two moving frames 4, and the worm reduction motor 2 causes the double-threaded rod 22 to rotate axially through the output shaft. The two ends of the double-threaded rod 22 cause the two moving frames 4 to move linearly along the guide rod 3 through threads, and the two moving frames 4 move in opposite directions, so that the two ends of the cloth winding roller are respectively placed in the rotating cylinder 20 of the clamping mechanism 6 on the two moving frames 4, and one of the rotating rods 10 is rotated. The two rotating rods 10 rotate synchronously through the spline shaft 7 and the spline sleeve 8. When the rotating rod 10 rotates, the transmission gear 18 on the rotating rod 10 rotates accordingly, and the transmission gear 18 causes the rotating cylinder 20 to rotate through the driven gear ring 19 meshing with it. When the rotating cylinder rotates, the bevel gear ring rotates accordingly, and the bevel gear ring rotates through the driven bevel gear meshing with it, and the internal threaded sleeve on the driven bevel gear rotates accordingly, and the internal threaded sleeve moves linearly along the spline column through the external threaded sleeve until the contact roller contacts the cloth winding roller.
