[0025] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0026] Example:

[0027] Reference Figure 1 As shown, this embodiment provides a wrapping device for cargo box packaging, including a base 1, a rotating disk 2 rotatably arranged on the base 1, and a linear module 3 arranged on one side of the rotating disk 2, and a mounting seat 4 that can move along the height direction of the linear module 3 is slidably mounted on the linear module 3; a film frame 5 is provided on the mounting seat 4.

[0028] The film rack 5 is mainly used to install a film roll. It should be noted that the existing film roll is mainly composed of a tubular sleeve and a film wound on the sleeve.

[0029] Specifically, the linear module 3 includes a vertical beam 31 and a servo motor 32. The vertical beam 31 is provided with a sliding groove 311 extending along the height direction of the vertical beam 31; the mounting seat 4 is slidably installed in the sliding groove 311 close to the side of the sliding groove 311, and a vertically arranged lead screw 33 is rotatably connected in the sliding groove 311. The servo motor 32 is installed on the top of the vertical beam 31 to drive the lead screw 33 to rotate; the lead screw 33 is threadedly connected to the mounting seat 4.

[0030] In this way, the servo motor 32 only needs to drive the lead screw 33 to rotate, which can drive the mounting seat 4 to move up and down, and then drive the film frame 5 with the film roll to move up and down. At the same time, the rotating disk 2 drives the cargo box to rotate, so that the cargo box can be gradually wrapped around.

[0031] Combination Figure 2 As shown, the film rack 5 includes a turntable 51 rotatably mounted on the mounting base 4, and a first motor 52 mounted on the mounting base 4 for driving the turntable 51 to rotate; it should be noted that, in order to make the overall weight of the turntable 51 lighter, in this embodiment, a plurality of arc-shaped cutouts 514 recessed toward the center of the turntable 51 are opened on the peripheral wall of the turntable 51, which is equivalent to cutting off the four sides of the turntable 51 to reduce the dead weight of the turntable 51.

[0032] The first motor 52 is fixedly mounted on the bottom of the mounting base 4 , and its main shaft is fixedly connected to the lower wall of the turntable 51 to drive the turntable 51 to rotate.

[0033] The turntable 51 is provided with a plurality of vertically arranged support rods 53 for inserting the film roll, and specifically, the support rod 53 comprises a rod body 531 and a tray 532 fixedly mounted on the rod body 531. The rod body 531 is cylindrical for inserting the sleeve of the film roll, and the tray 532 is mainly used to support the bottom of the film roll.

[0034] A vertically arranged column 54 is fixedly mounted on the turntable 51, and a plurality of supporting arms 55 corresponding to the supporting rods 53 are arranged on the column 54, wherein a notch 551 for the supporting rod 53 to be inserted is formed at an end of the supporting arm 55 close to one end of the supporting rod 53, and the supporting arm 55 is arranged along the radial direction of the turntable 51; when the supporting rod 53 is inserted into the notch 551 of the supporting arm 55, the supporting arm 55 can limit the upper end of the film roll to prevent the film roll from moving up and down along the supporting rod 53 during the unwinding and winding process, or even escaping from the upper end of the supporting rod 53.

[0035] Combination Figure 3 and Figure 4As shown, the rotating disk 51 is also provided with a driving mechanism 6 for driving all the supporting rods 53 to move toward or away from the center of the rotating disk 51 at the same time. In this way, all the supporting rods 53 can be driven to disengage from the notch 551 or insert into the notch 551 at the same time; when the film roll needs to be replaced, all the supporting rods 53 are disengaged from the notch 551 at the same time. At this time, without the restriction of the supporting arm 55, the sleeve of the film roll on the supporting rod 53 can be vertically pulled out upward, and then a new film roll can be re-installed on the supporting rod 53. After all the supporting rods 53 have replaced the film roll, the supporting rods 53 can be controlled to move back into the notch 551.

[0036] In this embodiment, Figure 3 As shown, a slide groove 511 extending radially along the turntable 51 is provided on the upper wall of the turntable 51 ; and a mounting groove 512 is provided at the center of the turntable 51 .

[0037] like Figure 3 and Figure 4 As shown, the driving mechanism 6 includes a slider 61 slidably installed in the slide groove 511, a threaded rod 62 rotatably connected in the slide groove 511 and arranged along the length direction of the slide groove 511, and a linkage assembly 63 installed on the turntable 51 to drive all the threaded rods 62 to rotate simultaneously; the slider 61 is threadedly connected to the threaded rod 62; the support rod 53 is vertically fixedly connected to the upper wall of the slider 61.

[0038] In this way, the slider 61 can be displaced along the length direction of the slide slot 511 when the threaded rod 62 rotates, thereby driving the support rod 53 to be displaced, so that the support rod 53 is inserted into or separated from the notch 551 of the support arm 55. The purpose of setting the linkage assembly 63 is to drive all the threaded rods 62 to rotate at the same time.

[0039] One end of the threaded rod 62 close to the mounting groove 512 extends into the mounting groove 512 .

[0040] like Figure 3 and Figure 4 As shown, the driving assembly includes a driven bevel gear 631 fixedly mounted on the threaded rod 62 at one end of the mounting groove 512, a driving bevel gear 632 arranged in the mounting groove 512 and meshing with all the driven bevel gears 631, and a second motor 633 connected to the driving bevel gear 632 for driving the driving bevel gear 632 to rotate; a cover plate 513 covering the mounting groove 512 is fixedly connected at the center of the upper wall of the turntable 51; the second motor 633 is fixedly mounted on the cover plate 513, and the main shaft of the second motor 633 is connected to the driving bevel gear 632.

[0041] Through the above arrangement, the second motor 633 drives the active bevel gear 632 to rotate, so that all the driven bevel gears 631 meshing with the active bevel gear 632 can rotate accordingly, thereby driving all the threaded rods 62 to rotate. At this time, all the sliders 61 start to move, and finally drive all the support rods 53 to move synchronously, so as to achieve the effect of simultaneously controlling all the support rods 53 to move closer to / away from the center of the turntable 51.

[0042] The cover plate 513 is fixedly mounted with a protective cover 634 covering the outside of the second motor 633, and the column 54 is vertically fixedly mounted on the top of the protective cover 634. It can be seen that in this embodiment, the protective cover 634 has two functions: first, it is used to protect the second motor 633, and second, it is used to install the column 54 to make the structure more compact.

[0043] In actual use, the width of the film roll (i.e., the axial length of the film roll) varies. Some film rolls are wider and some are narrower. In order to enable the support arm 55 to adapt to film rolls of various widths, this embodiment is further improved. Specifically:

[0044] The column 54 is slidably mounted with a movable block 7, specifically, as Figure 4 As shown, a slideway 541 extending axially along the column 54 is provided inside the column 54; the movable block 7 is slidably installed in the slideway 541; a through-opening 542 extending along the height direction of the column 54 and connected with the sliding is provided on the peripheral wall of the column 54, and the number of the through-openings 542 corresponds to the number of the support arms 55.

[0045] The end of the support arm 55 away from the support rod 53 passes through the opening 542 and is fixedly connected to the movable block 7; in this way, the movable block 7 can move axially along the column 54 to drive all the support arms 55 to move up and down, so as to adjust the height of the support arms 55 to adapt to the width of the film roll.

[0046] Among them, the column 54 is also provided with an adjustment mechanism for driving the movable block 7 to move axially along the column 54, and the adjustment mechanism includes a threaded shaft 81 that is rotatably connected in the slideway 541 and vertically arranged, wherein the upper end of the threaded shaft 81 passes through the column 54 and is fixedly connected to a hand wheel 82; the movable block 7 is threadedly connected to the threaded shaft 81.

[0047] Thus, the threaded shaft 81 can be driven to rotate by simply rotating the hand wheel 82, thereby driving the movable block 7 to move up and down, and finally driving the support arm 55 to move up and down, so as to adjust the height of the support arm 55 to adapt to the width of the film roll.

[0048] Implementation principle:

[0049] Before wrapping the cargo box, first install the film roll. The specific steps are as follows:

[0050] S1. The second motor 633 drives the active bevel gear 632 to rotate, and then the driven bevel gear 631 drives the threaded rod 62 to rotate, so that the threaded rod 62 drives the slider 61 to move away from the center of the turntable 51, until the support rod 53 on the slider 61 completely leaves the notch 551 of the support arm 55 for a distance, so that the support arm 55 no longer interferes with and limits the upper part of the support rod 53.

[0051] S2, vertically passing the film rolls through all the support rods 53 in sequence.

[0052] S3, controlling the second motor 633 to rotate in the reverse direction, thereby driving all the sliders 61 to move toward the side close to the center of the rotating disk 51 until the support rod 53 is embedded in the notch 551.

[0053] S4. The movable block 7 is driven to move by the adjusting mechanism, thereby driving all the supporting arms 55 to move up and down until the supporting arms 55 are close to the upper end of the film roll on the supporting rod 53. At this time, the supporting arms 55 can limit the upper end of the film roll to prevent the film roll from moving up and down significantly when unwinding.

[0054] After the film roll is installed, the cargo box can be placed on the rotating disk 2, the film roll located at the unwinding station (the unwinding station can be selected according to actual needs, such as the film roll close to the cargo box) is pulled out and wound around the outer wall of the cargo box, and the winding work can begin.

[0055] When the film roll at the unwinding station is used up, the first motor 52 drives the turntable 51 to rotate, and the next support rod 53 with the film roll is rotated to the unwinding station to continue the cargo box winding.

[0056] Repeat the above steps to use all the film rolls in sequence; after all the film rolls on the film rack 5 are used up, replace them with new film rolls, drive the support rod 53 away from the support arm 55 by the driving mechanism 6, remove the used film roll sleeve, and replace it with a new film roll.

[0057] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
