[0027] Please refer to Figures 1 - 6 , the present invention provides a technical solution: a multifunctional film sealing machine, including a machine body 1 and a conveying device 13. The side wall of the machine body 1 is connected with two symmetrically arranged conveyor belts 14 through two symmetrically arranged conveying mechanisms, and a plurality of connecting rods 11 are fixedly connected to the side walls of the conveyor belts 14. The other ends of the connecting rods 11 are fixedly connected with support plates 12, and the side walls of the support plates 12 are connected with an adsorption mechanism for adsorbing the sealed packaging bags through a reset mechanism. A peeling mechanism for detecting the peeling of the seal is arranged on the side wall of the support plate 12, and a pushing mechanism for pushing and separating unqualified packaging bags is arranged on the side wall of the machine body 1, which can automatically detect the seal of the sealed packaging bags online, making the detection of the seal more convenient and fast. Moreover, it can separately collect unqualified packaging bags with seals, improving the efficiency and effect of sealing.

[0028] Furthermore, each conveying mechanism includes a rotating rod 201 rotatably connected to the side wall of the machine body 1, and a conveyor roller 202 is fixedly sleeved on the side wall of the rotating rod 201.

An electromagnet 702 is fixedly connected to the side wall of the support plate 12, and a magnet 701 is fixedly connected to the side wall of the vacuum adsorption platform 301, which plays a role in guiding and resetting the movement of the vacuum adsorption platform 301. When it is necessary to reset the two vacuum adsorption platforms 301, the two vacuum adsorption platforms 301 are moved closer to each other for resetting.

[0031] Further, the peeling mechanism includes a connecting block 401 fixedly connected to the side wall of the vacuum adsorption platform 301. A moving block 402 is connected to the side wall of the connecting block 401 through a telescopic assembly. The movement of the moving block 402 is pulled by a pulling mechanism. After the vacuum adsorption platform 301 adsorbs both sides of the seal, the pulling mechanism is used to pull the moving block 402 to move, and the telescopic assembly is used to pull the two vacuum adsorption platforms 301. If the seal is unqualified, the seal will be pulled open. At this time, the two vacuum adsorption platforms 301 will move relative to each other.

[0032] Further, the telescopic assembly includes a fixed tube 501 fixedly connected to the side wall of the connecting block 401. A moving rod 502 is inserted into the fixed tube 501.

A scale mark is provided on the side wall of the connecting block 401. The rotation of the gear 901 drives the rotation of the rotating shaft 602 and the winding roller 603, and then the moving block 402 is pulled to move through the pulling rope 604, so that the second spring 503 is stretched. The two vacuum adsorption platforms 301 are pulled through the connecting block 401, and the deformation amount of the second spring 503 can be viewed through the scale mark, so as to determine the pulling force of the vacuum adsorption platform 301 on the seal.

[0033] Furthermore, the pulling mechanism includes a connecting plate 601 fixedly connected to the side wall of the support plate 12, and the side wall of the connecting plate 601 is rotatably connected to a winding roller 603 through a rotating shaft 602, a pull rope 604 is wound around the side wall of the winding roller 603, and the other end of the pull rope 604 is fixed to the side wall of the moving block 402, the rotation of the rotating shaft 602 is driven by a driving mechanism, and the side wall of the support plate 12 is provided with a detection mechanism for detecting the movement of the vacuum adsorption platform 301, the rotating shaft 602 is driven to rotate by the driving mechanism, the rotation of the rotating shaft 602 drives the rotation of the winding roller 603, and then the moving block 402 is pulled to move by the pull rope 604, so that the second spring 503 is stretched, and the two vacuum adsorption platforms 301 are pulled through the connecting block 401.

[0034] Furthermore, the driving mechanism includes a gear 901 fixedly sleeved on the side wall of the rotating shaft 602, and the side wall of the body 1 is fixedly connected to two symmetrically arranged fixing plates 902, the side wall of the fixing plate 902 is fixedly connected to the mounting plate 903, and the side wall of the mounting plate 903 is detachably connected to a rack 904 by bolts, and the rack 904 is meshed with the gear 901. When the gear 901 is meshed with the rack 904, the gear 901 rotates, and the rotation of the gear 901 drives the rotation of the rotating shaft 602 and the winding roller 603. By replacing different racks 904, the deformation amount of the second spring 503 being stretched can be adjusted, and then the pulling force of the vacuum adsorption platform 301 on the sealing part can be adjusted, and the applicability is stronger.

[0035] Furthermore, the detection mechanism includes a mounting block 801 fixedly connected to the side wall of the support plate 12, and a distance sensor 802 is fixedly inserted into the side wall of the mounting block 801. When the seal is pulled open, the vacuum adsorption platform 301 will move.

[0037] Working principle: When in use, when sealing, the packaging bag is placed on the conveying device 13 for conveying. At the same time, during the conveying process, the packaging bag is sealed by the machine body 1, and the sealed packaging bag continues to be conveyed;

[0038] When the seal is conveyed between the two vacuum adsorption platforms 301, the exhaust fan 302 is started to extract air, so that the vacuum adsorption platform 301 adsorbs both sides of the seal, and the electromagnet 702 is powered off. When the gear 901 is meshed with the rack 904, the gear 901 rotates, and the rotation of the gear 901 drives the rotation of the rotating shaft 602 and the winding roller 603, and then the moving block 402 is pulled to move through the pull rope 604, so that the second spring 503 is stretched, and the two vacuum adsorption platforms 301 are pulled through the connecting block 401. If the seal is unqualified, the seal will be pulled apart. At this time, the two vacuum adsorption platforms 301 will move relative to each other, so that after the seal is completed, the seal of the packaging bag can be automatically peeled off and tested, so as to ensure the quality of the seal and make the detection of the seal more convenient and quick.

[0039] When the seal is pulled open, the vacuum adsorption platform 301 will move. At this time, the distance sensor 802 is used to detect the movement of the vacuum adsorption platform 301 to determine whether the seal is qualified. When the detection is unqualified, the cylinder 1001 is started, so that the telescopic end 1002 drives the push plate 1003 to extend outward and push the unqualified packaging bag off the conveying device 13 for collection, thereby facilitating the separate collection of the packaging bags with unqualified seals and improving the efficiency and effect of the sealing.
