[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses a film feeding device.

[0036] Reference Figure 1 The film feeding device includes two feeding rollers 1, a feeding shaft 2 and three film rolls 3. The two ends of the two feeding rollers 1 are rotatably connected to one side of the frame 6 of the laminating machine, and one end of the feeding shaft 2 is rotatably connected to the frame 6 located on one side of the feeding roller 1. The two feeding rollers 1 are parallel to the feeding shaft 2 and are arranged, and the distances between the two feeding rollers 1 and the feeding shaft 2 relative to the frame 6 are different.

[0037] The three film rolls 3 are respectively sleeved on the two feeding rollers 1 and the feeding shaft 2, and the three film rolls 3 are spaced apart along the length direction of the feeding roller 1, and the distance between the two film rolls 3 is determined according to the actual blank part length of the cardboard.

[0038] In actual application, the two feeding rollers 1 and the feeding shaft 2 provide an installation base for the three film rolls 3, and the three film rolls 3 are arranged at intervals along the length direction of the feeding roller 1, so that there is a gap between two adjacent film rolls 3. The length of the gap is the length of the unprinted part of the cardboard. In this way, only the printed part of the cardboard can be laminated to reduce the amount of film used, thereby effectively reducing the lamination cost of the cardboard.

[0039] Reference Figure 2 and Figure 3 In some embodiments, each feeding roller 1 is provided with a mounting assembly 4 at both ends. Specifically, the mounting assembly 4 includes a mounting plate 41 and a bearing sleeve 42. The mounting plate 41 is fixedly connected to the frame 6, and a downwardly facing snap-in groove 411 is provided at the upper end of the mounting plate 41. The ends of the feeding roller 1 are configured with reduced diameters. The inner ring of the bearing sleeve 42 is sleeved and fixed to the end of the feeding roller 1. The diameter of the bearing sleeve 42 is smaller than the diameter of the middle portion of the feeding roller 1. The outer ring of the bearing sleeve 42 is snap-fitted into the snap-in groove 411, thereby enabling the feeding roller 1 to be rotatably connected to the frame 6. Furthermore, when the film roll 3 needs to be replaced, the feeding roller 1 is lifted upward to disengage the bearing sleeve 42 from the snap-in groove 411, thereby completing the disassembly of the feeding roller 1. This facilitates the disassembly and replacement of the film roll 3.

[0040] In some embodiments, the outer ring of the bearing sleeve 42 is provided with a limiting groove 421 along its own circumference. When the bearing sleeve 42 is clamped in the clamping groove 411, the bottom wall of the mounting plate 41 is located in the limiting groove 421 to limit the displacement of the bearing sleeve 42 along the length direction of the feeding roller 1, so as to improve the stability of the clamping of the bearing sleeve 42. In this way, the displacement of the feeding roller 1 can be avoided as much as possible, thereby improving the accuracy and stability of the cardboard lamination.

[0041] Reference Figure 3 In some embodiments, the mounting assembly 4 further includes a pressure block 43, a handle 44, a first gear 45 and a second gear 46. One end of the pressure block 43 is rotatably connected to the upper end of the mounting plate 41, and the other end of the pressure block 43 abuts against the outer ring of the bearing sleeve 42. The handle 44 is rotatably connected to one side of the mounting plate 41. The first gear 45 is fixedly connected to the pressure block 43 to rotate with the pressure block 43. The second gear 46 is fixedly connected to the handle 44 to rotate with the handle 44, and the first gear 45 is meshed with the second gear 46. After the bearing sleeve 42 is engaged with the engaging groove 411, the second gear 46 is driven to rotate by turning the handle 44, so that the first gear 45 drives the pressure block 43 to rotate, so that the end of the pressure block 43 away from the rotation abuts against the bearing sleeve 42, so as to improve the installation stability of the bearing sleeve 42, thereby improving the installation stability of the feeding roller 1. When the feeding roller 1 needs to be disassembled, the bearing sleeve 42 can be disengaged from the engaging groove 411 by turning the handle 44, which is simple and convenient to operate.

[0042] In some embodiments, the mounting assembly 4 also includes a clamping member 47, which is threadedly connected to the pressure block 43 and pressed against the bearing sleeve 42. When the pressure block 43 abuts against the feeding roller 1, the clamping member 47 is rotated so that the clamping member 47 is pressed against the bearing sleeve 42, further improving the installation stability of the bearing sleeve 42, thereby further improving the installation stability of the feeding roller 1.

[0043] Reference Figure 2 and Figure 3 In some embodiments, the film feeding device further includes two limiting assemblies 5, each of which is provided on the two feeding rollers 1. Specifically, the limiting assemblies 5 include two limiting rings 51, which are mounted on the feeding rollers 1 and respectively abut against two sides of the film roll 3 to limit the position of the film roll 3 and minimize relative displacement between the film roll 3 and the feeding rollers 1, thereby ensuring the accuracy and stability of the cardboard lamination.

[0044] In some embodiments, the limiting assembly 5 further includes two abutment bolts 52. Two limiting rings 51 are slidably connected to the feeding roller 1, sliding in the direction of the length of the feeding roller 1. The two abutment bolts 52 are respectively threadedly connected to the two limiting rings 51 and abut against the feeding roller 1 to secure the limiting rings 51. Sliding the limiting rings 51 and securing them with the abutment bolts 52 allows for adjustment of the position of the film roll 3, resulting in more precise lamination of the cardboard. It also accommodates film rolls 3 of different sizes, improving applicability.

[0045] The implementation principle of this embodiment is as follows: in actual application, the two feeding rollers 1 and the feeding shaft 2 provide a mounting base for the three film rolls 3, and the three film rolls 3 are spaced apart along the length direction of the feeding roller 1, so that there is a gap between two adjacent film rolls 3. The length of the gap is the length of the unprinted part of the cardboard. In this way, only the printed part of the cardboard can be laminated, thereby reducing the amount of film used and effectively reducing the lamination cost of the cardboard.

[0046] The embodiment of the present application also discloses a segmented cardboard laminating machine.

[0047] The segmented cardboard laminating machine includes the film loading device described in the above embodiment.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
