[0053] The rotating support mechanism 9 includes a fixed block 91, an adjusting ring 92, a connecting rod 93, an operating ring 94, a supporting spring 95, a fixed straight rod 96, a supporting joint 97 and a supporting straight plate 98.

The connection mode is a sliding connection, and the fixed block 91 and the rotating support mechanism 9 are an integrated structure. At the same time, the fixed block 91 is distributed at equal angles on the rotating support mechanism 9.

According to the snap-fitting of the supporting straight plate 98 on the supporting joint 97 and the limiting groove 13, the position of the lifting and lowering adjustment sleeve 12 on the outer side of the stable square column 11 can be fixed to avoid loosening of the arc buffer pad 16 on the subsequent arc positioning plate 15 after being fitted with the inner wall of the film roll. At the same time, the overall positioning is released, and it can be simply pulled by the positioning straight plate 64, which is convenient and fast to operate.

[0055] The working principle of this embodiment: Figure 1-2 and Figure 7-8When the laminating process for outer packaging is required, the film roll assembly needs to be assembled. The assembly fixing plate 1 can be bolted and installed to the equipment in the production area through the installation through hole 2 and installed on both sides of the appropriate equipment. Then, appropriate debugging can be performed according to the overall length of the film roll. The operating pull rod 65 can be manually pulled, and the operating pull rod 65 drives the limit block 63 and the positioning straight plate 64 to slide and shift. The limit block 63 pushes the reset spring 66 to shrink inside the fixed U frame 62, which facilitates the sliding separation of the positioning straight plate 64 and the positioning groove 8 on the supporting straight column 7, and releases the supporting straight column 7 from the load-bearing support. After the fixing work on the block 6, the supporting straight column 7 is pushed and pulled as needed, so that the supporting straight column 7 slides and shifts on the load-bearing supporting block 6 through the regular hexagonal notch 61, and the supporting straight column 7 moves on the supporting combination square frame 3 through the connecting square groove 5. The supporting straight column 7 drives the connecting head 10 to move by rotating the supporting mechanism 9, and the spacing between the connecting heads 10 can be adjusted. After the adjustment work is completed, the operating pull rod 65 is released, and the limit block 63 and the positioning straight plate 64 are reset by the elastic force of the reset spring 66, so that the positioning straight plate 64 slides into the other positioning strip grooves 8 and is fixed in a suitable position;

[0056] According to the figure Figure 1-6 At the same time, when the supporting straight column 7 is adjusted to slide and shift, the film roll is sleeved on the outer side of the arc-shaped positioning plate 15 and the arc-shaped buffer pad 16 in advance. During the sleeve connection process, the operating ring 94 is manually pulled, and the operating ring 94 drives the connecting straight rod 93 to slide on the fixed block 91, and the connecting straight rod 93 drives the adjusting ring 92 to slide and shift on the rotating support mechanism 9, and the adjusting ring 92 pushes the supporting spring 95 to retract and operate. At the same time, the adjusting ring 92 drives the supporting straight plate 98 to slide and separate from the limiting groove 13 through the fixed straight rod 96 and the supporting joint 97, and the fixing work of the lifting and adjusting sleeve 12 can make the lifting and adjusting sleeve 12 extend and retract. The elastic force of the spring 14 pushes the sliding displacement on the stable square column 11, so that the lifting and adjusting sleeve 12 drives the arc positioning plate 15 and the arc buffer pad 16 to move, and the arc buffer pad 16 is tightly fitted with the inner wall of the film roll to achieve the support work, and then the operating ring 94 is loosened, so that the supporting spring 95 pushes the adjusting ring 92 to slide and reset through the elastic force, and the adjusting ring 92 drives the fixed straight rod 96 and the supporting joint 97 to move, and the supporting joint 97 drives the supporting straight plate 98 to slide into and engage with the limiting groove 13 on the lifting and adjusting sleeve 12 again for stabilization, so as to avoid loosening during the subsequent rotation of the film roll, which is beneficial to the overall support, thereby completing a series of tasks.
