Detailed Implementation

[0024] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] Please refer to Figures 1-3 The image shows a schematic diagram of the overall structure of an automatic PET plastic strapping palletizing machine.

[0026] This embodiment provides an automatic palletizing machine for PET plastic steel strapping, including a base 1, a palletizing platform 2, and a lifting platform 3;

[0027] The palletizing platform 2 is supported above the base 1 by the support column 4, and a through hole 21 is provided in the center of the platform 2; a conveyor plate 5 is inclined on one side of the palletizing platform 2, and the far end of the conveyor plate 5 is connected to the end of the conveyor belt used for conveying the packing strap; multiple arc-shaped positioning plates 6 are provided around the periphery of the palletizing platform 2, and the side of each positioning plate 6 away from the through hole 21 is connected to the telescopic mechanism 7.

[0028] The lifting platform 3 is movably disposed in the through hole 21, and its bottom is connected to the lifting mechanism 8 disposed in the base 1.

[0029] The following will further describe an automatic PET plastic strapping machine according to this exemplary embodiment.

[0030] In some embodiments, the palletizing platform 2 is supported above the base 1 by support columns 4, and has a certain lifting space between it and the base 1. A through hole 21 is provided in the center of the palletizing platform 2 for mounting a lifting platform 3. A conveyor plate 5 is inclinedly arranged on one side of the palletizing platform 2, and the far end of the conveyor plate 5 is connected to the end of a conveyor belt used for conveying packing straps; that is, the packing straps are conveyed by the conveyor belt to the conveyor plate 5, and then conveyed to the palletizing platform 2 by the inclined conveyor plate 5. Multiple arc-shaped positioning plates 6 are spaced around the periphery of the palletizing platform 2, and the side of each positioning plate 6 away from the through hole 21 is connected to a telescopic mechanism 7. The telescopic mechanism 7 drives multiple positioning plates 6 to move simultaneously toward the center of the palletizing platform 2, pushing the packing straps conveyed to the edge of the palletizing platform 2 onto the lifting platform 3 at the center. The lifting platform 3 is movably arranged in the through hole 21, and its bottom is connected to the lifting mechanism 8 provided on the base 1. The lifting mechanism 8 drives the lifting platform 3 to move up and down. Specifically, after the packing strap is pushed to the center and fixed on the lifting platform 3, the lifting platform 3 moves down a certain distance. When the next packing strap is pushed to the top of the previous one and overlaps, multiple packing straps are stacked in sequence until the required number or height of stacks is reached, at which point the stacked packing straps can be bundled together. Through the above structural design, this application can realize automatic conveying and stacking of packing straps, improve stacking efficiency, and the positioning plate 6 positions each stacked packing strap to the center position, ensuring concentric stacking and preventing collapse.

[0031] It should be noted that the lifting platform 3 mentioned above can be circular or square, preferably circular, to accommodate packing straps with stacked rings. Its diameter is set to be relatively large so as to support packing straps with different stacking thicknesses.

[0032] The aforementioned telescopic mechanism 7 can be a telescopic cylinder, a telescopic electric cylinder, or other structures, which are existing technologies and will not be described in detail.

[0033] In a preferred embodiment, the conveyor plate 5 includes an inclined base plate 51 and side plates 52 disposed opposite to each other on both sides of the base plate 51. A guide plate 53 parallel to the inner side of each side plate 52 is telescopically connected to it. Multiple guide wheel sets 54 are rotatably embedded in the sidewalls of the guide plates 53 along their length, and these guide wheel sets 54 are driven to rotate synchronously by a drive mechanism. By providing guide plates 53 and guide wheel sets 54 on the conveyor plate 5, the packing strap can be guided and conveyed. Furthermore, the telescopic connection of the guide plates 53 to the inner side of the side plates 52 allows the two side plates 52 to move closer or further apart, thus accommodating packing straps with different stacking thicknesses.

[0034] In a preferred embodiment, the side plate 52 is provided with a threaded adjusting rod 55. One end of the threaded adjusting rod 55 is connected to the outer side of the guide plate 53, and the other end of the threaded adjusting rod 55 extends to the outer side of the side plate 52 and is provided with an adjusting handle 551. Adjustment is achieved by rotating the handle 55, which moves the guide plate 53 along the side plate 52, thereby adjusting the distance between the two guide plates 53 so that they fit snugly against both sides of the strapping strap, thus assisting in the transmission of the strapping strap to the palletizing platform 2.

[0035] In a preferred embodiment, the plurality of guide wheel sets 54 are spaced apart along the length of the guide plate 53 and rotatably mounted on the guide plate 53 via rotating shafts 56. The driving mechanism includes a driving component 57, transmission gears 58, and a toothed belt 59. One end of the rotating shaft 56 of each guide wheel set 54 is fitted with a transmission gear 58, and the plurality of transmission gears 58 are connected via the toothed belt 59. The rotating shaft 56 of one of the guide wheel sets 54 is connected to the output end of the driving component 57. The driving component 57 drives one of the rotating shafts 56 to rotate, causing the guide wheel set 54 mounted on that shaft to rotate. Simultaneously, the toothed belt 59 and transmission gears 58 drive the remaining rotating shafts 56 and guide wheel sets 54 to rotate synchronously, thereby conveying the packing strap on the conveyor plate 5. The driving component 57 can be composed of a drive motor and a reducer, capable of adjusting the rotational speed, thereby adjusting the rotational speed of the guide wheels to ensure stable and smooth conveying of the packing strap.

[0036] As a preferred embodiment, the guide wheel assembly 54 includes at least two guide wheels arranged vertically, with the two guide wheels spaced apart and mounted on the same rotating shaft 56 to improve transmission efficiency.

[0037] In a preferred embodiment, four positioning plates 6 are provided at the four corners of the palletizing platform 2, and support platforms 22 extend outward from the four corners of the palletizing platform 2. Telescopic mechanisms 7 are installed on the support platforms 22, and their telescopic ends are connected to the outer sides of the positioning plates 6. The support platforms 22 facilitate the installation of the telescopic mechanisms 7, and the absence of extended platforms on the four sides of the palletizing platform 2 facilitates the bundling operation of the stacked packing straps. By providing four positioning plates 6, located at the four corners, bundling operations and the transport of packing straps to the palletizing platform 2 are facilitated, while simultaneously ensuring the stable pushing of the packing straps towards the center of the lifting platform 3. During pushing, the four telescopic mechanisms 7 move synchronously by the same length, ensuring that the straps are pushed towards the center, thereby ensuring the concentricity of the stacked packing straps.

[0038] In a preferred embodiment, the palletizing platform 2 is provided with grooves 23 extending toward the center of the lifting platform at its four corners, and a slider is provided at the bottom of the positioning plate 6 that is slidably embedded in the grooves 23. The grooves 23 and the slider can guide and limit the movement of the positioning plate 6, preventing it from shaking or shifting, which would cause deviation in the pushing position of the packing strap.

[0039] As a preferred embodiment, the top surface of the aforementioned lifting platform is provided with a silicone rubber anti-slip pad 31. The silicone anti-slip pad can increase the friction between its platform and the packing straps, so that when the packing straps are stacked in sequence, the packing straps located on the lifting platform 3 can always sit stably on the lifting platform 3, avoiding collapse and displacement.

[0040] It should be noted that when stacking the packing straps sequentially, after each packing strap is stacked, the lifting platform 3 moves down to a certain position below the palletizing platform 2. After the positioning plate 6 pushes the packing strap to the center position, the positioning plate 6 releases the packing strap, allowing it to fall onto the packing strap on the lifting platform 3 for stacking. This ensures that when multiple positioning plates 6 push the packing strap on the palletizing platform 2 to the center position, they do not rub against the packing strap on the lifting platform 3, preventing the stacked packing straps from collapsing. It should also be noted that the distance the lifting platform 3 moves down to below the palletizing platform 2 is relatively small, preferably 5cm from the top surface of the through hole 21. This avoids friction and also prevents excessive height differences that could lead to excessive gravitational impact during stacking, causing collapse.

[0041] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application.
