Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of winding packaging, in particular to a folding mechanism for folding paper corner protection. Background Art
[0002] The paper corner protectors on the market are mainly L-shaped paper corner protectors. With its straight structural characteristics, the L-shaped paper corner protectors can provide strong support and protection at the edges of the goods, effectively preventing the goods from being damaged due to collision or extrusion during transportation. However, L-shaped paper corner protectors have some inherent problems in transportation and storage. L-shaped paper corner protectors often take up a large space, especially when piled up in large quantities, which not only increases the transportation cost, but also increases the difficulty of handling and management. In addition, L-shaped paper corner protectors also face the risk of being crushed during transportation. Once damaged, it will directly affect the protective effect of the goods. In response to these problems, a folding paper corner protector with a crease in the middle came into being. The folding paper corner protector is in an unfolded state when placed, so that it will not be crushed during transportation. When using it, you only need to fold it along the crease, which is convenient and quick.
[0003] When using the folding paper corner protector, the staff only needs to manually bend it along the crease, then align the two sides of the folding paper corner protector with the corners of the product to be packaged, and then wrap the product with film to wrap the product and the folding paper corner protector together.
[0004] However, in actual application, the folded paper corner protector often expands outward after being bent, resulting in that its two sides cannot fit tightly against the corners of the product. When wrapping the product with film, gaps will be created between the two sides of the folded paper corner protector and the corners of the product, greatly reducing the protective effect of the folded paper corner protector on the product. Summary of the invention
[0005] The utility model aims to solve the problem that when a folding paper corner protector is manually bent, gaps will be generated between the two sides of the folding paper corner protector and the corners of the product, resulting in poor protection effect. The utility model provides a folding mechanism for a folding paper corner protector which can be bent by a cylinder, so that no gaps will be generated between the two sides of the folding paper corner protector and the corners of the product and the protection effect is good.
[0006] In order to solve the above problems, the technical solution adopted by the utility model is a folding mechanism for a folding paper corner protector, including a bracket, a fixing device is fixed at the lower end of the bracket, a flap is hinged on the fixing device, a cylinder is arranged on the flap, the mounting end of the cylinder is hinged to the bracket, and the telescopic end of the cylinder is hinged to the flap. The fixing device can fix one side of the folding paper corner protector, and the other side of the folding paper corner protector is in close contact with the flap. When the folding paper corner protector needs to be bent, the telescopic end of the cylinder is controlled to extend, the flap starts to rotate around the hinge, and the other side of the folding paper corner protector is bent along the crease. When the other side of the folding paper corner protector is in close contact with the product, the telescopic end of the cylinder is stopped from extending. The folding paper corner protector is bent and fixed, and the two sides of the folding paper corner protector are in close contact with the product, ensuring that no gap will be generated between the two sides of the folding paper corner protector and the corners of the product during subsequent film wrapping, thereby improving the protection effect.
[0007] Preferably, the fixing device comprises a suction cup seat, the side edge of the suction cup seat is hinged to the side edge of the flap, and a suction cup is installed on the suction cup seat. The method of fixing the folded paper corner protector with a suction cup is convenient and safe, and can ensure that the folded paper corner protector is not damaged during the fixing process.
[0008] Preferably, the suction cup seat is provided with a long slot hole, and the suction cup is installed in the long slot hole, and the suction cup can slide and lock along the length direction of the long slot hole. The suction cup can easily slide and lock in the long slot hole, which is convenient for flexibly adjusting the position of the suction cup to meet different fixing requirements.
[0009] Preferably, at least four suction cups are provided, and the suction cups are evenly distributed on both sides of the suction cup seat. The evenly distributed suction cups can provide stable and balanced adsorption force.
[0010] Preferably, a mounting seat is fixed on the flap, a fisheye joint is provided on the mounting seat, a joint bearing end of the fisheye joint is hinged to the mounting seat, and a connecting rod end of the fisheye joint is fixedly connected to the telescopic end of the cylinder.

[0011] Preferably, a photoelectric mounting frame is provided on the suction cup seat, and a photoelectric sensor is fixed on the photoelectric mounting frame. The photoelectric sensor can accurately detect whether the suction cup has successfully adsorbed the folded paper corner protector, thereby ensuring the reliability of the fixing effect.
[0012] Preferably, a mounting plate is provided on the bracket, one side of the mounting plate is fixedly connected to the bracket, and the other side of the mounting plate is hinged to the mounting end of the cylinder. The position of the cylinder can be adjusted by the mounting plate, so that the extension and retraction operation of the telescopic end of the cylinder can be easily realized.
[0013] It can be seen from the above technical solutions that the advantages of the utility model are: the suction cup fixes one side of the folding paper corner protector, and the other side of the folding paper corner protector fits tightly with the flap. When it is necessary to bend the folding paper corner protector, by controlling the extension of the telescopic end of the cylinder, the flap can be driven to rotate, so that the other side of the folding paper corner protector is bent along the preset crease. Once the bent portion of the folding paper corner protector fits tightly with the surface of the product, the telescopic end of the cylinder stops extending, thereby ensuring that the folding paper corner protector is bent and fixed on the product. In summary, this mechanism effectively fixes both sides of the folding paper corner protector, ensuring that there will be no gap between the folding paper corner protector and the corners of the product during the subsequent film wrapping process, significantly improving its protective effect on the product.

Correspondingly, at least four suction cups 12 are also provided, and all the suction cups 12 are evenly distributed on both sides of the suction cup seat 8. In this embodiment, as Figure 3 As shown, there are six long slot holes 15 in total, three of which are located on one side of the suction cup seat 8, and the other three are located on the other side of the suction cup seat 8, and suction cups 12 are installed in the six suction cup seats 8.
[0024] like Figure 2 As shown, a photoelectric mounting frame 13 is also provided on the suction cup seat 8, and the photoelectric mounting frame 13 is located in the middle of the suction cup seat 8. A photoelectric sensor 14 is installed on the photoelectric mounting frame 13, and the photoelectric sensor 14 is fixedly connected to the photoelectric mounting frame 13 by bolts, and the detection port of the photoelectric sensor 14 is directly facing the folded paper corner guard 11. When the suction cup 12 fixes the folded paper corner guard 11, the photoelectric sensor 14 will detect the folded paper corner guard 11, and start the driving device to start bending the folded paper corner guard 11.
[0025] In this specific embodiment, the driving device specifically adopts the following structure: the driving device includes a cylinder 3, and the mounting end of the cylinder 3 is hinged to the upper end of the bracket 1. In this embodiment, a mounting plate 2 is provided at the upper end of the bracket 1, one side of the mounting plate 2 is fixedly connected to the bracket 1 by bolts, and a through hole is provided on the other side of the mounting plate 2, and a connecting shaft is installed in the through hole, and both ends of the connecting shaft are fixed to the mounting end of the cylinder 3 by bolts.

Use the suction cup 12 to firmly adsorb one side of the folding paper corner protector 11, and ensure that the rotating shaft 6 is perfectly aligned with the fold of the folding paper corner protector 11. Once the photoelectric sensor 14 detects the folding paper corner protector 11, start the cylinder 3 immediately. The telescopic end of the cylinder 3 extends rapidly, pushing the flap 9 to rotate downward around the rotating shaft 6. During the rotation of the flap 9, it drives the other side of the folding paper corner protector 11 to bend downward along the fold. When both sides of the folding paper corner protector 11 are tightly fitted to the corners of the product, the cylinder 3 stops working. At this time, the film wrapping process starts to tightly wrap the folding paper corner protector 11 and the product together.
[0029] It can be seen from the above embodiments that the beneficial effect of the utility model is that the suction cup fixes one side of the folding paper corner protector, and the other side of the folding paper corner protector fits tightly with the flap. When it is necessary to bend the folding paper corner protector, by controlling the extension of the telescopic end of the cylinder, the flap can be driven to rotate so that the other side of the folding paper corner protector is bent along the preset crease. Once the bent portion of the folding paper corner protector fits tightly with the surface of the product, the telescopic end of the cylinder stops extending, thereby ensuring that the folding paper corner protector is bent and fixed on the product. In summary, this mechanism effectively fixes both sides of the folding paper corner protector, ensuring that there will be no gap between the folding paper corner protector and the corners of the product during the subsequent film wrapping process, significantly improving its protective effect on the product.
