The ball shaft 31 on the unwinding film roller 3 is used to sleeve the film on the outer wall of the support block and adjust the position, and then the handle 81 is manually turned to rotate the adjusting block 8, squeezing the slider 7 to slide toward the fixing seat 4, and then squeezing the first connecting rod 61 and the second connecting rod 62, pushing the support plate out until the outer wall of the support plate is tightly fitted with the film roll, and finally putting the ball shaft 31 back into the mounting groove 21, so as to accurately fix the film roll and be suitable for film rolls of different specifications. When disassembling, it is only necessary to reversely rotate the adjusting block 8 to release the squeezing of the slider 7 on the connecting rod, and use the restoring force of the spring 5 to reset the slider 7 and the support plate, and lift the film roller 3 to easily take out the film roll. The whole process ensures the stable and convenient installation and disassembly of the film roll, greatly improving the operating efficiency and the convenience of equipment use.

[0030] See also Figure 1 - Figure 4 The ball shaft 31 is symmetrically arranged at both ends of the film roller 3, and the outer diameter of the ball shaft 31 is larger than the outer diameter of the film roller 3, and the outer diameter of the ball shaft 31 is smaller than the width of the mounting frame 2, so that the film roller 3 is easy to install and disassemble.

[0031] See also Figure 1 - Figure 4 The depth of the mounting groove 21 is greater than the outer diameter of the ball shaft 31, and the top of the mounting groove 21 passes through the top outer wall of the mounting frame 2, so that the film roller 3 can be easily placed in the mounting groove 21 without affecting the normal rotation of the film roller 3.

[0032] See also Figure 1 - Figure 4 The outer wall of the support block 6 is designed to be arc-shaped, and there are multiple groups of support blocks 6 at equal angles on the outer wall of the film roller 3, and the end corners of the support block 6 are designed to be beveled, so that the outer wall of the support block 6 fits tightly with the inner wall of the film roll, ensuring the stability of the installation. The bevel is conducive to the installation of the film roll.

[0033] See also Figure 2 - Figure 4 The first connecting rod 61 and the second connecting rod 62 are both arranged corresponding to the support block 6, and the first connecting rod 61 and the second connecting rod 62 are symmetrically arranged on the outer wall of the support block 6 close to the film roller 3, so that the first connecting rod 61 and the second connecting rod 62 can rotate to squeeze the support plate, so that the support plate is stretched to fix the film.

[0034] See also Figure 2 - Figure 4 The slider 7 and the adjusting block 8 are both designed in a circular ring shape, and the adjusting block 8 is located on the outer wall of the slider 7 away from the fixed seat 4, and the outer wall of the film roller 3 is provided with a thread for the adjusting block 8 to be threadedly connected, so that the adjusting block 8 is screwed to squeeze the slider 7 to open the support plate and fix the film roll.

[0035] See also Figure 2 - Figure 4 One end of the spring 5 fits with the outer wall of the slider 7, and the other end of the spring 5 fits with the outer wall of the fixing seat 4, so that when the adjusting block 8 is turned in the opposite direction, the spring 5 automatically resets the slider 7, and the film roll can be easily taken out.

[0036] The working principle of the present invention is as follows: when installing the film roll, the ball shaft 31 on the film roll roller 3 away from the fixing seat 4 is manually taken out from the mounting bracket 2, and then the film roll is put on the outer wall of the support block, and the position of the film roll is carefully adjusted to ensure that its end is tightly fitted with the fixing seat 4. Next, the rotary handle 81 is manually turned to make the adjusting block 8 start to rotate. During its rotation, the extrusion slider 7 slides toward the fixing seat 4. After the slider 7 is subjected to force, it exerts an extrusion effect on the first connecting rod 61 and the second connecting rod 62, causing the two connecting rods to rotate, thereby pushing the support plate out in the direction away from the film roll roller 3. This process continues until the outer wall of the support plate is tightly fitted with the inside of the film roll and the adjusting block 8 can no longer be twisted. At this time, the film roll is firmly fixed. Finally, the ball shaft 31 is placed in the mounting groove 21 at the end of the mounting bracket 2, thus achieving a stable and convenient installation operation of the film roll.

[0037] When removing the film roll, it is only necessary to reversely rotate the adjusting block 8 to release the squeezing state of the slider 7 on the first connecting rod 61 and the second connecting rod 62. Under the restoring force of the spring 5, the slider 7 slides following the adjusting block 8, thereby releasing the restrictive effect of the support plate on the film roll. After that, the film roll 3 is lifted and the film roll is taken out, and the convenient disassembly process can be easily realized.
