Description

Technical Field

[0001] The utility model relates to a film roll quick disassembly and assembly mechanism, belonging to the technical field of film sticking equipment. Background Art

[0002] Film laminating equipment is mainly used to apply various types of protective films to metal coils before cutting, while ensuring that the film adhered to the surface of the metal coils is free of bubbles and scratches, thereby protecting the product surface from damage.

[0003] like Figure 1 As shown, in the film-sticking equipment in the prior art, the expansion core shaft for installing the film roll is fixed at one end and movable at the other end. The film roll is disassembled and installed on the movable side, which requires operators to complete the work within the production line. In addition, it is difficult to locate the center of the film roll, which increases the labor intensity of the operators. The disassembly and assembly time is long, and the production line needs to be shut down, making it impossible to carry out production operations, thereby reducing production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a film roll quick disassembly and assembly mechanism for the above-mentioned prior art, which is convenient to operate, reduces the labor intensity of operators, and improves production efficiency.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a film roll quick disassembly and assembly mechanism, including two bearing seats, an expansion shaft is provided between the two bearing seats, and the film roll is fixed on the expansion shaft; clamping pieces are respectively provided in the center of the bearing seats, and the two ends of the expansion shaft are clamped in the corresponding clamping pieces; when the clamping pieces are opened, the expansion shaft is disengaged from the clamping pieces.

[0006] The clamping piece is a safety clamp, and the center of the safety clamp corresponds to the center of the expansion shaft.

[0007] The bearing seat is a sliding bearing seat, and the distance between the two sliding bearing seats matches the expansion shaft.

[0008] The sliding bearing seats are respectively fixed on the base, and reinforcing ribs are arranged between the base and the sliding bearing seats.

[0009] There are a plurality of expansion shafts, and membrane rolls are respectively provided on the plurality of expansion shafts as spare parts.

[0010] Compared with the existing technology, the advantages of this utility model are: a quick film roll disassembly and assembly mechanism. During disassembly, the safety clamp is opened and the expansion shaft inside the production line is lifted out by a lifting device, achieving rapid disassembly of the film roll. The expansion shaft with the film roll outside the production line is then lifted between the two safety clamps by the lifting device and the two safety clamps are closed, securing the expansion shaft inside the two safety clamps. This application is easy to operate, reduces the labor intensity of the operator, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the existing film roll disassembly and assembly structure;

[0012] Figure 2 This is a schematic diagram of a film roll quick disassembly and assembly mechanism according to an embodiment of the present utility model;

[0013] In the figure, 1 is the base, 2 is the sliding bearing seat, 3 is the safety chuck, 4 is the expansion shaft, and 5 is the reinforcing rib. DETAILED DESCRIPTION

[0014] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 2 As shown, a quick film roll assembly and disassembly mechanism in this embodiment includes two sliding bearing seats 2, with an expansion shaft 4 positioned between the two sliding bearing seats 2, and the film roll secured to the expansion shaft 4. The spacing between the two sliding bearing seats 2 matches the expansion shaft 4, and the sliding bearing seats 2 are each secured to a base 1. Safety clamps 3 are positioned at the center of the inner rings of the sliding bearing seats 2. The expansion shaft 4 is clamped within the corresponding safety clamps 2 at each end, with the centers of the safety clamps corresponding to the centers of the expansion shafts. This allows the expansion shafts to be installed within the sliding bearing seats, achieving both installation and centering of the film roll. When the safety clamps are opened, the expansion shaft disengages from the safety clamps, allowing the film roll to be removed.

[0016] A reinforcing rib 5 is provided between the base and the sliding bearing seat to improve the connection strength between the sliding shaft bearing seat and the base.

[0017] Several expansion shafts are provided. Operators install the specified membrane roll onto the expansion shaft outside the production line according to product requirements. The expansion shaft expands and secures the membrane roll, serving as a spare part. During disassembly, the safety chuck is opened and the expansion shaft inside the production line is lifted using a lifting device, enabling quick disassembly of the membrane roll. The expansion shaft, with the membrane roll attached, is then hoisted between the two safety chucks using the lifting device. The two safety chucks are then closed, securing the expansion shaft within them. This application is convenient to operate, reduces operator workload, and improves production efficiency.

[0018] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
