A fixed shaft 13 is inserted between the first clamping assembly and the second clamping assembly. A winding roller 2 is sleeved on the outer wall of the fixed shaft 13. The rotating shaft on one side of the first clamping assembly is driven by a drive motor.
[0024] The first clamping assembly includes a first fixing ring 11, a first clamping arc block 111 is fixedly installed on the clamping surface of the first fixing ring 11, a second arc-shaped clamping assembly 112 is inserted above the first clamping arc block 111, a limiting assembly 3 is sleeved on one side of the clamping surface of the first fixing ring 11 outside the first clamping arc block 111 and the second arc-shaped clamping assembly 112, and the first clamping arc block 111, the second arc-shaped clamping assembly 112 and the first fixing ring 11 are limited and fixed by the limiting assembly 3, and the second clamping assembly includes a second fixing ring 12, an extending protruding ring 121 is provided on the side of the second fixing ring 12 near the clamping surface.
[0025] Furthermore, the second arc-shaped clamping assembly 112 includes a second clamping arc block. A first extension seat is installed in the middle of both the first clamping arc block 111 and the second clamping arc block. After the first clamping arc block 111 and the second arc-shaped clamping assembly 112 are inserted, a first locking cavity is formed. The inner diameter of the first locking cavity is consistent with the outer diameter of the fixed shaft 13. The cross-sectional area of the first extension seat is not greater than the cross-sectional area of the T-shaped protrusion.
[0026] Meanwhile, a limiting ring is installed on one side of the second clamping arc block. A groove is provided inside the limiting ring at the first extension seat, and the cross-sectional area of the limiting ring is consistent with the cross-sectional area of the first clamping cavity.
[0027] Meanwhile, four T-shaped protrusions are installed in a ring at equal intervals inside the winding roller 2, and a sliding groove is opened on the outer wall of the fixed shaft 13 at the T-shaped protrusions, and an auxiliary sliding groove is opened on one side of the fixed shaft 13 at the first extension seat.
[0028] Furthermore, a second locking cavity is provided on one side of the clamping surface of the extended convex ring 121 at the fixed shaft 13, and a limit block is installed in the second locking cavity at the slide groove.
[0029] Furthermore, multiple limiting rods 115 are symmetrically installed at equal intervals on both sides of the clamping surface of the first clamping arc block 111, and locking grooves are provided on both sides of the clamping surface of the second clamping arc block at the limiting rods 115.
[0030] Furthermore, two sets of T-shaped fixing blocks 114 are installed at equal intervals on the outer walls of the first clamping arc block 111 and the second clamping arc block, and L-shaped fixing blocks 113 are installed on the outer walls of the first clamping arc block 111 and the second clamping arc block near the clamping surface.
[0031] Furthermore, the limiting component 3 includes a T-shaped annular slider 31.

[0033] In this embodiment, the winding roller is driven by a drive motor to rotate and the packaging film is wound. After winding, the limiting ring is rotated so that the T-shaped limiting block 33 is aligned with the groove cavity and inserted. Then, the T-shaped ring slider 31 is slid into the first clamping arc block 111 until the second clamping arc block can be separated. Then, the winding roller 2 drives the fixed shaft 13 to move towards the first fixed ring 11, so that one end of the fixed shaft 13 is away from the second clamping cavity. Then the fixed shaft 13 and the winding roller can be taken out and the winding roller can be separated.
[0034] After replacing the winding roller, fit the winding roller onto the fixed shaft 13, aligning its T-shaped protrusion with the slide groove. Then, align the fixed shaft 13 with the first clamping arc block 111 and insert it. Next, rotate the second fixed ring 12 until the limiting block aligns with its slide groove. Move the fixed shaft 13 until one side of the fixed shaft 13 is inserted into the second clamping cavity. Insert the second arc-shaped clamping assembly 112 onto the first clamping arc block 111. Move the T-shaped annular slider 31 away from the first fixed ring 11 and fit the first clamping arc block 111 onto the second arc-shaped clamping assembly 112 until the limiting ring is outside the first fixed ring 11. Rotate the first fixed ring 11 so that the T-shaped limiting block 33 of the first fixed ring 11 is in an interlaced state with the slide groove cavity to complete the installation of the winding roller.
[0035] In this invention, the winding roller can be quickly assembled and disassembled by the first clamping component and the second clamping component. The entire assembly and disassembly process is quick and convenient, and does not require complicated tools or cumbersome operations, while reducing the replacement time of the winding roller.
