Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0031] Firstly, this utility model provides a film roll unwinding device, such as... Figures 1 to 4 As shown, it includes a placement rack 2, a support frame 4, and a mounting base plate 1; the placement rack 2 is mounted on the mounting base plate 1 via the support frame 4; the placement rack 2 is used to place the tube core, and the mounting base plate 1 is used to fix it to the lifting trolley.
[0032] In this embodiment, the placement plate 2 is used to place the core of the film roll and support the film roll. The height of the support frame 4 is greater than the radius of the film roll, so that the film roll is suspended in the air and does not come into contact with the platform of the lifting trolley. Therefore, the film roll will not deform and the quality of the film roll is guaranteed.
[0033] Meanwhile, since the placement rack 2 and the support frame 4 are both rigidly connected, the film roll will not shake when placed on the placement rack 2, so it will not collide with surrounding equipment, operators and other environmental factors, and will not cause safety hazards, thus improving safety during use.
[0034] Specifically, in this embodiment, the minimum height of the placement rack 2 is at least 20mm greater than the radius of the film roll to ensure the placement stability of the film roll and to prevent accidental collision between the film roll and the platform of the lifting trolley when moving the film roll, thus ensuring the quality of the film roll.
[0035] In use, two template roll unwinding devices are used, which are respectively set at opposite ends of the film roll to support the two ends of the core of the film roll, thereby achieving the effect of supporting the film roll.
[0036] In an optional embodiment, the vertical cross-sectional shape of the placement shelf 2 is semi-circular or arc-shaped.
[0037] In this embodiment, the core of the film roll is circular, and the placement rack 2 is bent to form a placement groove structure. The shape of the placement groove is a semi-circular groove or an arc-shaped groove, that is, the vertical cross-section of the bottom surface of the placement groove is semi-circular or arc-shaped, so as to fully support the core of the film roll, ensuring both the stability of the support and the balance of the support force.
[0038] It is understood that in this embodiment, the shape of the placement groove formed by the placement rack 2 can be a semi-circular groove or an arc-shaped groove, but it is not limited to a semi-circular groove or an arc-shaped groove. It can also be other types of groove structures, such as rectangular grooves, trapezoidal grooves, dovetail grooves, triangular grooves, etc., as long as it can support the core of the film roll.
[0039] In an optional embodiment, the mounting base plate 1 is provided with a plurality of mounting holes 3.
[0040] In this embodiment, the mounting holes 3 on the mounting base plate 1 are arranged in a straight line and the arrangement direction is perpendicular to the axis of the mounting frame plate 2.
[0041] The multiple mounting holes 3 ensure the stability and connection strength of the mounting base plate 1. Their arrangement direction better supports the core of the film roll without generating shear force, thus ensuring the stability and balance of the support force.
[0042] In an optional embodiment, there are multiple support frames 4, and the multiple support frames 4 are arranged symmetrically with respect to the placement shelf 2.
[0043] In this embodiment, the support frame 4 is a vertical plate structure, with multiple vertical plates arranged below the placement frame plate 2 and symmetrically arranged on opposite sides of the placement frame plate 2. This ensures both the stability and the support strength of the placement frame plate 2.
[0044] In this embodiment, the support frame 4 is a vertical plate structure, but it is not limited to this one setting. It can also be a rod structure, that is, multiple support rods support the placement plate 2, etc. In other words, as long as it can support the placement plate 2, it is acceptable.
[0045] In an optional embodiment, the two ends of the support frame 4 are welded to the placement frame plate 2 and the mounting base plate 1, respectively.
[0046] In this embodiment, when the support frame 4 is a vertical plate or rod structure, the upper end of the support frame 4 is welded to the lower end of the placement plate 2, and the lower end of the support frame 4 is welded to the mounting base plate 1, thereby ensuring the connection stability and connection strength of the two ends of the support frame 4.
[0047] It should be noted that in this embodiment, the upper and lower ends of the support frame 4 are welded to the placement frame plate 2 and the mounting base plate 1 respectively. However, it is not limited to welding. It can also be other fixed connection methods, such as integral setting, bolt fixing, snap-fit, riveting, etc. In other words, as long as the placement frame plate 2, the support frame 4 and the mounting base plate 1 can be fixedly connected together to form an integral unloading fixture, it is acceptable.
[0048] Secondly, this utility model provides a lifting platform trolley, such as... Figure 3 and Figure 4 As shown, it includes two film roll unwinding devices as described in any of the aforementioned embodiments; the two film roll unwinding devices are respectively disposed at both ends of the raised platform 5.
[0049] In this embodiment, the lifting platform 5 is horizontally set, and the mounting base plate 1 of the film roll unloading device is fixedly set on the upper surface of the lifting platform 5, so that the film roll unloading device can be erected on the lifting platform 5.
[0050] Two film roll unwinding devices are respectively installed at opposite ends of the upper surface of the lifting platform 5, thereby supporting the two ends of the film roll core.
[0051] In an optional embodiment, the raised platform 5 is provided with a fork tooth opening 6 for engaging with the fork teeth of a forklift.
[0052] In this embodiment, there are two fork tooth openings 6, and the two fork tooth openings 6 are respectively set to correspond to the two fork teeth of the forklift.
[0053] Specifically, in this embodiment, the width of the fork tooth opening 6 is greater than the width of the fork tooth of the forklift, thereby ensuring that the fork tooth can be smoothly inserted into the fork tooth opening 6 to realize the movement and transportation of the raised platform 5.
[0054] In this embodiment, the fork tooth 6 can be a hole structure or a groove structure, and its specific design can be determined according to the thickness of the raised platform 5.
[0055] Specifically, in this embodiment, such as Figure 2 As shown, the fork tooth opening 6 is a groove structure, wherein the groove depth of the fork tooth opening 6 is half the thickness of the lifting platform 5, thereby ensuring the strength of the lifting platform 5 and allowing the fork tooth to be smoothly inserted into the fork tooth opening 6.
[0056] In an optional embodiment, the width of the inlet end of the fork 6 is greater than the width of the other end.
[0057] In this embodiment, the shape of the horizontal cross section of the fork tooth opening 6 is set as trapezoidal, and the width of its entrance end is greater than the width of the other end, which facilitates the insertion of the fork tooth into the fork tooth opening 6.
[0058] In this embodiment, the width of one end of the fork tooth opening 6 is greater than the width of the fork tooth, and the width of the other end is less than or equal to the width of the fork tooth.
[0059] This configuration allows the fork teeth to be inserted more smoothly into the wider end and into the fork tooth opening 6, while the narrower end of the fork tooth opening 6 can be used to position the fork teeth and also achieve alignment, thus ensuring the stability and balance of the forklift when raising the platform 5 with the flag inserted.
[0060] In an optional embodiment, the lifting platform 5 is provided with multiple sets of adjustment holes, and the film roll unwinding fixture cooperates with different adjustment holes to adjust the distance between the two film roll unwinding fixtures.
[0061] In this embodiment, the adjustment holes on the raised platform 5 are correspondingly provided with the mounting holes 3 on the mounting base plate 1, so that after the bolt passes through the mounting holes 3 and the adjustment holes, the bolt is fixed by the nut, thereby achieving the purpose of fixing the mounting base plate 1 on the raised platform 5.
[0062] Specifically, in this embodiment, in each group of adjustment holes, the adjustment hole and the mounting hole 3 are set in a one-to-one correspondence.
[0063] More specifically, in this embodiment, the adjustment holes are set in multiple groups. When the mounting base plate 1 is set with different groups of adjustment holes, the distance between the two film roll unwinding fixtures set at both ends of the film roll core can be adjusted to accommodate cores of different lengths.
[0064] In an optional embodiment, the thickness h of the raised platform 5 is: h≥15mm.
[0065] In this embodiment, the lifting platform 5 needs to take into account the actual weight of the film roll. The thickness of the lifting platform 5 is preferably greater than or equal to 15mm, which is suitable for unwinding rolls with small widths (i.e., width ≤ 1.2m).
[0066] The film roll unloading device and lifting trolley provided in this embodiment of the utility model support the core of the film roll by setting up a support frame 4 and a placement rack 2, so that the film roll can be detached from the platform of the lifting trolley, avoiding deformation of the film and ensuring product quality; the core is placed directly on the placement rack 2, ensuring stability during movement and preventing safety hazards such as collisions with equipment or operators.
[0067] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
