[0002] A wrapping device is a mechanical device used in the logistics and packaging industries to stabilize and protect goods to prevent damage caused by impact, vibration, and other factors during transportation. This device wraps the product or pallet by rotating a plastic film or other elastic material around it, providing a solid outer layer of protection.

[0003] Existing automated wrapping and strapping technologies still require manual operation, especially during the initial stages, when the wrapping material must be manually secured. This reliance on manual labor not only increases labor intensity but can also lead to inconsistent operation, compromising packaging quality. In particular, the leading and trailing ends of the wrapping material can easily come loose during or after the wrapping process, resulting in a loose package and compromising the safety of the items during transport. Furthermore, the uncertainty of manual operation can lead to uneven wrapping, compromising the aesthetics and practicality of the package.

[0004] In order to solve the above technical problems, the present invention designs an automatic winding and bundling device. Utility Model Content

[0028] like Figure 1 As shown, an automatic winding and bundling device is characterized by comprising a conveyor belt 1, a rotating table 2, a feeder 3, a puller 4 and a hot melt fixing device 5 arranged in sequence;

[0029] like Figure 2As shown, the conveyor belt 1 includes a conveyor support 11 and a conveyor belt 13. The conveyor belt 13 is mounted on the conveyor support 11. A conveyor motor 12 is mounted on the conveyor support 11 to move the conveyor belt 13. A baffle 14 is also mounted on the conveyor support 11. The baffle 14 helps define the position of items, preventing them from shifting or falling during conveyance. This is particularly effective for small or irregularly shaped items. The length and height of the conveyor belt 1 can be adjusted to meet the conveying needs of different production lines.

[0030] like Figure 3 As shown, the rotating platform 2 includes a rotating bracket 21 and a rotating motor 23 . The rotating platform 22 is provided on the rotating bracket 21 . The rotating motor 23 is fixed to the rotating bracket 21 . The output end of the rotating motor 23 is connected to the rotating platform 22 .

[0031] like Figure 4 As shown, the feeder 3 includes a feed bracket 31 and a feed motor 32. The feed bracket 31 is provided with a rotating shaft 33, and the rotating shaft 33 is detachably mounted with a winding material 34. The feed motor 32 is mounted on the feed bracket 31, and its output end is connected to the rotating shaft 33. Since the winding material 34 can be easily removed from the rotating shaft 33, cleaning or replacing the material becomes simpler and faster, and it also facilitates inspection and maintenance of the rotating shaft 33.

[0032] The wrapping material 34 is made of PE film, polypropylene film, polyvinyl chloride film, or a composite film, so that the wrapping material 34 can be fixed by heat pressing. A self-adhesive film material is used. This film naturally adheres to itself or other surfaces when in contact, thereby increasing the stability of the wrapping material 34.

[0033] like Figure 5 As shown, the material puller 4 includes a material pulling bracket 41 and a material pulling motor 42. The material pulling bracket 41 is fixedly connected to the material pulling motor 42. The output end of the material pulling motor 42 is connected to the driving wheel 43. The driven wheel 44 is installed on the material pulling bracket 41. The belt 45 is installed between the driving wheel 43 and the driven wheel 44. A sliding seat 46 is provided on the belt 45. The sliding seat 46 is rotatably connected to the clamping member 47. A guide rail 411 is fixedly connected to the material pulling bracket 41, and the sliding seat 46 slides on the guide rail 411. A rubber pad is provided on the clamping member 47. The material pulling motor 42 controls the tension of the belt 45 between the driving wheel 43 and the driven wheel 44, thereby controlling the pulling force of the clamping member 47 on the winding material 34. Such a mechanism can ensure that the winding material 34 maintains appropriate tension during winding, avoiding looseness caused by excessive slackness of the material or breakage caused by excessive tension.

[0034] The main function of the clamping member 47 is to fix one end of the winding material 34 at the beginning of winding to prevent the material from loosening during the winding process. After one end of the winding material 34 is fixed by the clamping member 47, the feeder 3 will continue to supply material and evenly wrap the material around the object through the rotation of the turntable 2. If the clamping member 47 does not correctly fix the material, then during the rotation of the turntable 2, one end of the material may become loose and be entangled around the object as it rotates, resulting in uneven winding or chaotic material. The clamping member 47 is bolted to the sliding seat 46. The bolts on the clamping member 47 can be adjusted to control the distance between the sliding seat 46 and the clamping member 47 so that the sliding seat 46 and the clamping member 47 can clamp the winding material 34.

[0035] like Figures 6 to 8 As shown, the hot melt fixing device 5 includes a hot melt bracket 51, a slider 52 and a hot melt fixing plate 54. The hot melt bracket 51 is provided with a slide groove 511, and the slider 52 is slidably connected to the slide groove 511. One end of the connecting rod 53 is connected to the slider 52, and the other end is detachably connected to the hot melt fixing plate 54. The hot melt fixing plate 54 is fixed with a telescopic cylinder 55, and the free end of the piston rod of the telescopic cylinder 55 is connected to a fixed pressure head 57. The fixed pressure head 57 is connected to the hot melt fixing plate 54 through a telescopic rod 56.

[0036] The hot melt fixing plate 54 is provided with a rotating portion 541 at both ends. The rotating portion 541 is rotatably connected to the hot melt fixing plate 54. The rotating portion 541 is provided with a connecting hole 542, and the connecting hole 542 is used to connect the connecting rod 53. Through the design of the rotating portion 541, the hot melt fixing plate 54 can rotate to a certain angle, so that the hot melt fixing plate 54 can accurately contact the part that needs to be fixed in different directions, increasing the flexibility of the device. The rotating portion 541 allows the hot melt fixing plate 54 to adjust its angle in space, which enables the device to better adapt to items of different shapes and sizes, especially when handling complex or irregularly shaped items, allowing for more precise hot melt fixing. Connecting the connecting rod 53 through the connecting hole 542 forms a detachable connection between the hot melt fixing plate 54 and the connecting rod 53, making it convenient to maintain or replace the hot melt fixing plate 54.

[0037] An electric heating plate is provided on the fixed pressure head 57 .

[0038] During use, the article is first placed on the conveyor belt 1 and then transported by the conveyor belt 1 or moved by a robot to the position of the rotary table 2. The baffle 14 on the conveyor belt 1 can help prevent the article from deviating during the transport process.

[0039] When the article arrives at the rotating platform 2, a device capable of positioning or fixing the article is provided on the rotating platform 22 on the rotating platform 2. The article is positioned and is ready to be wound in the next step.

[0040] The wrapping material 34 is pre-installed on the rotating shaft 33 of the feeding bracket 31, and the feeding motor 32 drives the wrapping material 34 to rotate through the rotating shaft 33, preparing to provide the wrapping material 34 to the object.

[0041] The clamping member 47 fixes one end of the winding material 34. The pulling motor 42 drives the sliding seat 46 to slide on the guide rail 411 through the belt 45 on the driving wheel 43 and the driven wheel 44, and the clamping member 47 stretches the winding material 34. The rubber pad provided on the clamping member 47 can prevent damage to the material.

[0042] The fixed pressure head 57 in the fusion fixing device 5 is connected to the hot melt fixing plate 54 via a telescopic rod 56. The telescopic cylinder 55 is extended, and after the electric heating plate on the fixed pressure head 57 is heated, the fixed pressure head 57 presses the wrapping material 34 against the object, thereby bonding it. After bonding, the telescopic cylinder 55 retracts, and the fixed pressure head 57 moves away from the wrapping material 34.

[0043] The rotary motor 23 drives the rotating table 22 to rotate, so that the winding material 34 is evenly wrapped around the article. In this process, the feeder 3 continues to provide material. Now, the winding material 34 of the clamping member 47 is loose and is also entangled around the article.

[0044] When the winding is completed, the hot melt fixing device 5 uses the electric heating plate on the fixed pressure head 57 again to heat the tail end of the winding material 34 and fix it on the article to ensure that the tail end will not loosen.

[0045] Finally, the staff cuts off the excess winding material 34 manually or with a cutting device, completing the entire winding and bundling process.

[0046] It should be noted that the positioning seat or clamp and cutting device in this embodiment are universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0047] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
