[0030] Please refer to Figures 1-6 As shown, a rotary wrapping device of the present utility model includes a base 1, a rotary seat 2, a limiting structure, and a driving mechanism. The rotary seat 2 is rotatably connected to the base 1 around its axis. The limiting structure is arranged on the rotary seat 2 and forms a limiting cavity 31 for the article to be wrapped. The limiting cavity 31 is coaxially arranged with the rotary seat 2, and an opening 32 for the article 10 to enter is formed at one end of the limiting cavity 31 away from the rotary seat 2. When wrapping the article 10 placed in the limiting cavity 31, one end of the sheet for wrapping the article 10 enters the limiting cavity 31 from the outside of the limiting structure and is pressed between the limiting structure and the article 10. The driving mechanism drives the rotary seat 2 to rotate, so that the sheet is wound around the periphery of the limiting structure. Preferably, the rotation axis of the rotary seat 2 is inclined upward relative to the horizontal plane, and the inclination angle is small, so as to prevent the article 10 from falling out of the limiting cavity 31 when the rotary seat 2 rotates.

[0031] In this embodiment, the limiting structure includes a plurality of limiting members 3. The plurality of limiting members 3 are installed on the rotary seat 2 and extend along the axial direction of the rotary seat 2. Specifically, the article 10 to be wrapped is a cylindrical article such as a bottle (such as a wine bottle, etc.) or a jar. The plurality of limiting members 3 are circumferentially spaced apart on the rotary seat 2, so that a limiting cavity 31 is formed between the plurality of limiting members 3 to adapt to the shape of the article 10 to be wrapped. In other embodiments, the limiting structure includes a limiting cylinder. The limiting cylinder is installed on the rotary seat and extends along the axial direction of the rotary seat. A limiting cavity is formed inside the limiting cylinder, an opening for the article to enter is formed at one end of the limiting cylinder away from the rotary seat, and an inlet for one end of the sheet to enter the limiting cavity is provided on the side surface of the limiting cylinder.

[0032] In this embodiment, the limiting member 3 is rod-shaped, so as to facilitate the removal of the wound sheet material around the plurality of limiting members 3. There are five limiting members 3. In other embodiments, the limiting member is an arc-shaped plate, and the plurality of limiting members are concentrically arranged.

[0033] Adjustment mechanisms are respectively provided between the plurality of position-limiting members 3 and the rotating base 2 , so that the plurality of position-limiting members 3 can respectively move along the radial direction of the rotating base 2 to adjust their positions.

[0034] The adjustment mechanism includes a sliding seat 4 and an adjusting bolt 5. The sliding seat 4 is connected to the rotating seat 2 in a sliding manner along the radial direction of the rotating seat 2. One end of the limiting member 3 is fixed to the sliding seat 4. The adjusting bolt 5 can be connected to the rotating seat 2 rotatably around its axis and is threadedly connected to the sliding seat 4 to drive the sliding seat 4 to slide by rotation. A mounting bracket 6 is fixed to the disk surface of the rotating seat 2 corresponding to each sliding seat 4, and the sliding seat 4 and the adjusting bolt 5 are respectively connected to the mounting bracket 6. A decorative plate 7 is also included. The decorative plate 7 is installed on each mounting bracket 6 and covers the mounting bracket 6 and the sliding seat 4, and a clearance opening 71 is provided on the decorative plate 7 corresponding to each limiting member 3. Specifically, as Figure 5 As shown, the rotating seat 2 is provided with sliding openings 21 corresponding to each limit member 3, the sliding seat 4 is slidably connected to the mounting bracket 6 along the radial direction of the rotating seat 2, the adjusting bolt 5 is rotatably connected to the mounting bracket 6 around its axis and is threadedly connected to the sliding seat 4, and protrusions 41 are respectively provided at both ends of the sliding seat 4, one of the protrusions 41 slides in the sliding opening 21, and the other protrusion 41 slides in the clearance opening 71.

[0035] The present invention also includes a positioning rod 8, which is connected to the same sliding seat 4 as one of the stoppers 3 and is distributed along the circumference of the rotating seat 2. One end of a sheet of material enters the stopper cavity 31 through the gap between the positioning rod 8 and one of the stoppers 3. This ensures that the gap through which the sheet of material passes is consistent when the adjustment mechanism adjusts the stopper 3, preventing the sliding seat 4 from moving the stopper 3 in the radial direction of the rotating seat 2, which could affect the placement of the sheet of material. Specifically, the positioning rod 8 is connected to one of the stoppers 3 via a connecting block 9.

[0036] The driving mechanism includes a motor, which drives the rotating seat 2 to rotate.

[0037] An automatic wrapping device of the present utility model includes a sheet conveying device and a cutting knife device, and further includes the rotary wrapping device described above. The sheet conveying device, the cutting knife device, and the rotary wrapping device are arranged in sequence. The sheet is output after being expanded and stretched by the sheet conveying device, and then automatically conveyed to the rotary wrapping device through the gap between the cutting knife devices. The cutting knife device cuts the sheet after the sheet is wound on the limiting structure. Specifically, the sheet is honeycomb paper. One end of the sheet extends into the limiting cavity 31, which can be achieved by arranging the positions of the sheet conveying device and the rotary wrapping device, or by setting a guiding plate to guide the sheet.

[0038] The working principle of an automatic wrapping device of the present utility model is as follows:

[0039] Put the article 10 into the limiting cavity 31. The rotary seat 2 is driven to rotate by a motor, and multiple limiting parts 3 fixed on the rotary seat 2 rotate synchronously to drive the sheet to rotate and wind around the limiting parts 3 and the article 10 in the limiting cavity 31. After the sheet wraps the article 10, the cutting knife device cuts the sheet. The rotary seat 2 stops rotating, and then the article 10 together with the sheet wound around the periphery of the multiple limiting parts 3 is taken out from one end of the multiple limiting parts 3. When there is no article 10 in the limiting cavity 31, the sheet conveying device automatically outputs a section of sheet, conveys one end of the sheet into the limiting cavity 31 and then stops, puts a new article into the limiting cavity 31, and the rotary seat 2 rotates to perform a new packing process.

[0040] An automatic wrapping device of the present utility model can also be provided with a sensor for sensing whether there is an article 10 in the limiting cavity 31 and sending a signal to the sheet conveying device or the rotary wrapping device to realize the automatic operation of the sheet conveying device and the rotary wrapping device.

[0041] An automatic wrapping device of the present utility model has high automation, improves the quality of wrapping, reduces the labor intensity of workers, can realize continuous automatic packing of packages, improves the packing efficiency of articles, and can adapt to articles of different sizes, thus enhancing the versatility of the device.

[0042] Regarding the structure and working principle of the rotary wrapping device of an automatic wrapping device of the present utility model, please refer to the previous description part thereof, and details will not be repeated here.

[0043] For a rotary wrapping device and an automatic wrapping device of the present utility model, the parts not involved are the same as the prior art or can be implemented by the prior art.
