The working principle of the invention is as follows:
The film-covering and sealing and cutting process for the light-weight package comprises the following steps: pre-feeding a film, sleeving the film, and sealing and cutting; the film pre-feeding is to avoid tilting and deformation of the light-weight package in the process of moving forward against the film, and before the pushing cylinder 24 pushes the package out of the pushing platform 2 for film covering, the film between the upper film roller 12 and the lower film roller 13 is loosened in advance, so that the light-weight package can be kept in a horizontal placement state and smoothly passes through the sealing line against the film during film covering, and film covering is smooth;
the film covering and sealing and cutting process of the heavy-weight package comprises the following steps: covering film and sealing and cutting;
The specific operation of pre-feeding the film is as follows: before the pushing cylinder 24 pushes the package out of the package pushing platform 2, the translation cylinder 23 drives the film pulling roller 22 to move forward, the film 11 wound between the third upper film guiding roller 93 and the fourth upper film guiding roller 94 is synchronously pulled to move forward when the film pulling roller 22 moves forward, the length of the film 11 wound between the third upper film guiding roller 93 and the fourth upper film guiding roller 94 is continuously increased along with the continuous forward movement of the film pulling roller 22, the length of the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92 is continuously reduced, the first proximity sensor 21 sends a signal to the first sensor 21 along with the continuous reduction of the length of the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92, the first sensor 21 rotates along with the continuous reduction of the length of the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92, the first rotating shaft 17 and the first detection disc 20 simultaneously drives the first film pressing roller 16, the first detection disc 20 rotates along with the continuous rotation of the first detection disc 20 until the first gap 201 and the first proximity sensor 21 are misplaced, the first proximity sensor 21 sends a signal to the first sensor 12 rotates along with the first rotating shaft 12, and the first reset rod 13 rotates along with the first reset rod 13, and the first reset rod is released, and the first film roll is released, and the first film is released from the first film roll is released from the first reset, and the first film roll is released from the first film roll and the first film roll is released;
The specific operation of the mantle is as follows: the pushing cylinder 18 is made to move the package on the pushing platform 2 towards the film wrapping platform 3 against the loosened film 19, the package is gradually collapsed and pushed to move forwards in the process of moving the package forwards against the loosened film, the package drives the film to move towards the film wrapping platform 3 along with the package, the length of the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92 and the length of the film 11 wound between the first upper film guiding roller 101 and the second upper film guiding roller 102 are simultaneously reduced, the length of the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92 is continuously reduced along with the fact that the film 11 wound between the first upper film guiding roller 91 and the second upper film guiding roller 92 synchronously drives the first film pressing roller 16, the first rotating shaft 17 and the first detecting disc 20, when the first detecting disc 20 rotates to the first gap 201 and the first proximity sensor 21 are misplaced, the first proximity sensor 21 senses the length of the first detecting disc 20, the first motor 21 is close to the first detecting disc 21 to send a signal to the first rotating shaft 12 to the first rotating stop lever 12, and the first detecting disc 19 rotates to the first rotating shaft 12 to the first film pressing roller 12, and the first stop lever is released by the first rotating shaft 12; meanwhile, as the length of the film 11 wound between the first lower film guiding roller 101 and the second lower film guiding roller 102 is continuously reduced, the film 11 wound between the first lower film guiding roller 101 and the second lower film guiding roller 102 synchronously drives the second film pressing roller 25, the second rotating shaft 26 and the second detecting disc 29 to rotate upwards, when the second detecting disc 29 rotates to the position where the second notch 291 is dislocated with the second proximity sensor 30, the second proximity sensor 30 senses the second detecting disc 29, at the moment, the second proximity sensor 30 sends a film releasing signal to the second motor 15, the second motor 15 receives the film releasing signal and then controls the lower film pressing roller 13 to rotate to release a section of film, and after the film is released by the lower film pressing roller 13, the second film pressing roller 25 presses the film to rotate downwards around the second rotating shaft 26 under the action of dead weight until the second connecting rod 27 is rested on the second limiting stop lever 28 again;
When the upper film roll 12 and the lower film roll 13 simultaneously put films, the pushing cylinder 24 continuously pushes the packaged objects to the film wrapping platform 3 against the films, when the packaged objects reach the film wrapping platform 3, the packaged objects are wrapped by the films at the moment, and then the pushing cylinder 24 is reset to complete film covering;
The specific operation of sealing and cutting is as follows: after the packaged object is pushed to the film wrapping platform 3, piston rods of the first lifting cylinder 6 and the second lifting cylinder 7 extend out simultaneously, and the sealing cutter 5 and the sealing base 4 are opposite up and down to seal and cut the film; when the anti-sticking cloth on the surface of the sealing cutter needs to be replaced, the two side shaft ends of the film feeding roller 33 and the two side shaft ends of the film collecting roller 34 are respectively corresponding to the fastening bolts 37, so that the film feeding roller 33 and the film collecting roller 34 can freely rotate, then the film collecting roller 34 is rotated, the anti-sticking cloth which needs to be replaced is gradually wound on the film collecting roller 34 in the rotation process of the film collecting roller 34, meanwhile, the new anti-sticking cloth can be gradually pulled out of the film feeding roller 33 and gradually covers the surface of the sealing cutter 5, after the sealing cutter 5 completely covers the new anti-sticking cloth, the two side shaft ends of the film feeding roller 33 and the two side shaft ends of the film collecting roller 34 are respectively corresponding to the fastening bolts 37, and the film feeding roller 33 and the film collecting roller 34 are clamped between the side plates 322 of the two mounting frames 32, so that the film feeding roller 33 and the film collecting roller 34 cannot freely rotate, and the replacement operation of the anti-sticking cloth is completed, and the replacement operation is extremely convenient.
