[0059] The embodiments of the present application will be further described below in conjunction with the drawings:

[0060] As shown in the drawings, a film connecting mechanism of a high-speed packaging machine comprises a mounting plate 1, a driving assembly 2 mounted on the mounting plate 1, a plurality of roller shafts 3 mounted on the mounting plate 1, and a first film suction component 4 and a second film suction component 5 connected to the output end of the driving assembly 2, wherein the first film suction component 4 and the second film suction component 5 are arranged side by side and oppositely, and the first film suction component 4 and the second film suction component 5 have a first action of horizontally approaching each other to complete film connection under the driving of the driving assembly 2 and a second action of moving away from each other after the film connection is completed; in the technical solution, the first film suction component and the second film suction component are driven by the driving assembly to perform circular motion respectively, one of the first film suction component and the second film suction component adsorbs the first end of the new packaging film and the other one has no adsorption force to the packaging film in operation, when the film connection is needed, the two approach each other until contact in the rotating process, at the time of contact, the two pieces of packaging film are adhered together by double-sided adhesive, then the adhered packaging film is pulled away by external force from above, the packaging film has small adsorption force and can be easily peeled off from the first film suction component or the second film suction component by light pulling force, and then the first film suction component and the second film suction component continue to rotate and move away from each other, which has the advantages of good stability of film connection work, improved flatness, firmness and efficiency of film connection in high-speed operation of the packaging machine.

[0061] The roller shafts adopt air expansion shafts and the number is two, one of which is installed with the packaging film in operation, and the other is installed with the new packaging film, which is in the preparatory stage.

[0062] The working principle of the embodiment is as follows: the first film suction component adsorbs the first end position of the new packaging film, the opposite side of the first end position is attached with double-sided adhesive, and the second film suction component does not exert adsorption force on the packaging film in operation; when the packaging film corresponding to the second film suction component is about to be used up, the photoelectric switch (not shown) sends a signal to the PLC (not shown), and the PLC sends a signal to the driving assembly to start working; the first film suction component and the second film suction component horizontally approach each other during rotation until they contact, and after the contact, the first elastic members on both sides contract, so that the suction cups on both sides move linearly for a distance after pressing the packaging film, and then the first film suction component and the second film suction component continue to rotate and move away from each other, so that the first end of the new packaging film is attached to the tail end of the packaging film in operation.

[0063] The first film suction component and the second film suction component in the embodiment alternately generate adsorption force, because during operation, the new packaging film will be gradually pulled until it is used up, in order to ensure that the machine does not stop, the roller shaft that has extracted the packaging film will be placed with a new packaging film; for example, the first film suction component adsorbs the first end of the new packaging film, and the second film suction component does not exert adsorption force on the packaging film in operation; when the two films are successfully bonded, the operator will place a new packaging film as a preparation on the roller shaft corresponding to the second film suction component, and the second film suction component will adsorb the first end of the new packaging film and bond it with the packaging film in operation.

[0064] The first film suction component 4 and the second film suction component 5 have the same structure and each include:

[0065] The mounting shaft 41 is connected with the output end of the driving assembly 2;

[0066] The fixed seat 42 is fixedly installed at the end of the mounting shaft 41 and is provided with a moving shaft 43 which is slidably installed and transversely arranged;

[0067] The suction cup seat 44 is elastically installed at the end of the moving shaft 43;

[0068] The side wall of the suction cup seat 44 is provided with a plurality of suction cup installation holes (not shown) or suction holes 45; the suction cup seats of the first film suction component and the second film suction component are oppositely arranged, and when they horizontally approach each other until they contact, they exert pressure on the two packaging films, so that the packaging films are bonded together by the double-sided adhesive; the interaction force between the two suction cup seats when they contact will make them retreat a distance along the moving shaft, and the flexible force is exerted on the packaging films, avoiding hard contact between them and causing damage and affecting the service life.

[0069] In addition, the suction cup holder is equipped with soft silicone, which improves the adhesion of the packaging film and protects the packaging film from damage due to pressure.

[0070] A mounting base 46 is provided between the suction cup seat 44 and the moving shaft 43 to fix the two. A first elastic element 47 is provided between the mounting base 46 and the fixed seat 42 and is fitted on the moving shaft 43. The first elastic element applies an elastic preload to the mounting base. After the two suction cup seats come into contact, they overcome the elastic preload of the first elastic element under the interaction force, thereby moving backward by an appropriate distance. The first elastic element is a spring.

[0071] Two rolls of packaging film are combined into one unit under the action of double-sided adhesive and the force from both sides. During this process, the two suction cups are always compressing each other, and the suction cups are always in contact with the packaging film. The two move together in a straight line along the traction direction of the packaging film for a certain distance. There may be a speed difference between the suction cups and the packaging film, or they may be relatively stationary. In actual production, it is preferred that the two are relatively stationary. When the two suction cups rotate to an appropriate angle, they release the pressure applied to each other, and the packaging film is also released from the suction cups under the action of the traction force above.
