[0050] S1. The paper shell sleeve is put on the outside of the winding roller 9 and the expansion tile 10. There are two sets of winding rollers 9 and expansion tiles 10, so that the torsion column 7 and the bending frame 701 can be twisted back and forth by 90 degrees, and the strip 201 is pulled out and bonded to the side wall of the paper shell sleeve at the upper position.

[0051] S2. The expansion shoe 10 applies elastic force outward through the return spring 904 at its bottom. The greater the tension of the return spring 904, the greater the friction force of the anti-skid sheet 1002 on the outer arc surface of the expansion shoe 10 on the paper shell sleeve.

[0052] S3. When the paper shell sleeve is full of the strip 201, the opening and closing cylinder 301 drives the moving platform 4 to move forward a unit distance, and then the strip 201 is located between the chopping knife 503 and the retention rod 6. The chopping cylinder 501 drives the chopping tile 502 and the chopping knife 503 to extend and fit to the outer arc surface of the retention rod 6. The chopping knife 503 cuts the strip 201 and temporarily adheres the strip 201 to the outer surface of the retention rod 6.

The winding device for producing automobile license plate reflective film according to claim 1, characterized in that: The winding roller assembly comprises bearings at the ends of two forked rods, the outer ring of the bearings being fixedly connected to the side walls of the forked rods, a central axis (901) being arranged in the inner ring of the bearings, a winding roller (9) being arranged at one end of the central axis (901), a winding power assembly being arranged at the other end of the central axis (901), and an expansion and compaction mechanism being arranged on the outer side of the winding roller (9).

4. The winding device for producing automobile license plate reflective film according to claim 3, characterized in that: The winding power assembly comprises a driven wheel (802) at the other end of the central shaft (901); a winding motor (8) is arranged on the side wall of the bending frame (701); a wheel set (801) is arranged on the output shaft of the winding motor (8); and the wheel set (801) is connected to the driven wheel (802) by winding with two belts (803).

5. The winding device for producing automobile license plate reflective film according to claim 3, characterized in that: The expansion compaction mechanism comprises four groups of threaded holes on the outer wall of the winding roller (9), a bolt rod (902) being rotatably arranged inside each threaded hole, a telescopic hole being arranged at the axis of the bolt rod (902), an insertion rod (903) being slidably inserted inside the telescopic hole, an expansion shoe (10) being arranged at the top of the insertion rod (903), a return spring (904) being sleeved on the outer side of the insertion rod (903), the bottom end of the return spring (904) being fixedly connected to the top end of the bolt rod (902), the top end of the return spring (904) being fixedly connected to the bottom surface of the expansion shoe (10), both ends of the expansion shoe (10) being arranged with inclined strips (1001), an anti-slip sheet (1002) being arranged on the outer arc surface of the expansion shoe (10), and paper shell sleeves being sleeved on the outer sides of the four expansion shoes (10).

6. The method of producing a winding device for automobile license plate reflective film according to claim 5, characterized in that: The following steps are involved: S1. The paper shell sleeve is sleeved on the outside of the winding roller (9) and the expansion tile (10). The winding roller (9) and the expansion tile (10) are provided in two groups, and the twisting column (7) and the bending frame (701) can be twisted back and forth by ninety degrees to pull out the strip (201) and bond it to the side wall of the paper shell sleeve at the upper position. The two groups of winding rollers (9) and the expansion tile (10) can be sleeved on the paper shell sleeve in turn, and the paper shell sleeve will not delay the winding operation when it is replaced, thereby increasing the time utilization efficiency; S2. The expansion shoe (10) applies elastic force outward through the return spring (904) at its bottom. The greater the tension of the return spring (904), the greater the friction force of the anti-skid sheet (1002) on the outer arc surface of the expansion shoe (10) on the paper shell sleeve. The staff replaces the return spring (904) of different types according to the processing needs. If the strip (201) is stuck, the anti-skid sheet (1002) will slip with the inner wall of the paper shell sleeve, thereby protecting the strip (201) from being torn off. S3. When the paper shell sleeve is full of the strip (201), the opening and closing cylinder (301) drives the moving platform (4) to move forward a unit distance, and then the strip (201) is located between the chopping knife (503) and the retention rod (6). The chopping cylinder (501) drives the chopping tile (502) and the chopping knife (503) to extend and fit onto the outer arc surface of the retention rod (6). The chopping knife (503) cuts the strip (201) and temporarily adheres the strip (201) to the outer surface of the retention rod (6). The closing cylinder (301) drives the movable platform (4) to retreat to the original position. When another paper shell sleeve reaches the rewinding position again, the opening and closing cylinder (301) drives the movable platform (4) to advance a unit distance. The stepping motor (401) drives the retention rod (6) to run along the rectangular track groove through the notch frame (404). After the retention rod (6) bypasses the paper shell sleeve, it will send the strip material (201) carried on its outer wall back to the paper shell sleeve, thereby achieving the effect of automatically pulling the strip material (201) and saving labor costs.
