DETAILED DESCRIPTION

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-3 As shown, an automated product packaging device includes a pushing mechanism 1 that pushes the product and protective film to a sealing and cutting mechanism 4, a film pressing mechanism 2 that presses the film onto the product, a film feeding mechanism 3 including an upper film feeding assembly 301 and a lower film feeding assembly 303, a sealing and cutting mechanism 4 for sealing and cutting the protective film to prevent tearing, and a PLC control system 5 for setting and adjusting the device. The upper film feeding assembly 301 is located at the top of the device near the pushing mechanism 1, the lower film feeding assembly 303 is located at the lower end of the pushing mechanism 1, the film pressing mechanism 2 and the sealing and cutting mechanism 4 are both located at the top of the device away from the pushing mechanism 1, and the PLC control system 5 is located on the side of the device.

[0019] The film feeding mechanism 3 includes an upper film feeding assembly 301, an upper film sleeve 302, a lower film feeding assembly 303, and a lower film sleeve 304. The upper film feeding assembly 301 and the lower film feeding assembly 303 are both composed of two rotating shafts driven by a motor. The upper film sleeve 302 is movably disposed between the rotating shafts of the upper film feeding assembly 301, and the lower film sleeve 304 is movably disposed between the rotating shafts of the lower film feeding assembly 303. The length of the film sleeve is slightly shorter than the length of the film feeding assembly. The rotation of the rotating shafts allows the film sleeve to rotate, thereby realizing the feeding or recycling of the protective film.

[0020] The film feeding mechanism 3's lower film feeding assembly 303 also includes a rocker roller 305, a sensing plate 306, and a sensor 307. The sensing plate 306 is fixedly installed at one end of the rocker roller 305. The rocker roller 305 is longitudinally slidably installed in a groove. The sensor 307 is fixedly installed at the bottom of the groove near the end of the sensing plate 306.

[0021] After the protective film of the lower film 304 passes through the rotating shaft of the lower film feeding assembly 303, it bypasses the swing arm roller 305 and comes into contact with the product. When the protective film is used for sealing, the swing arm roller 305 moves upward due to the stretching of the protective film. This is fed back to the PLC control system 5 through the sensor 307, thereby controlling the operation of the lower film feeding assembly 303 to ensure the delivery of the protective film. Similarly, when the use of the protective film is stopped, the swing arm roller 305 moves downward, thereby stopping the operation of the film feeding mechanism 3 through the feedback of the sensor 307.

[0022] The working principle of the up-and-down film feeding mechanism 3 is as follows: when the pushing cylinder works, the pushing force will make the up-and-down film tight and generate a pulling force, so that the swing rod roller 305 is lifted upwards, thereby driving the inductive sheet 306 to be separated from the inductor 307; at this time, the up-and-down film feeding motor works, and the film feeding is continuously performed, so that the film is relaxed, thereby preventing the up-and-down film from being torn; until the inductor 307 senses the inductive sheet 306, the up-and-down film feeding motor stops working, and the up-and-down film feeding mechanism 3 stops feeding the film.

[0023] The pushing mechanism 1 further comprises a material rack 101 and a material detector 102, the material rack 101 is shaped in accordance with the shape of the product, and the material detector 102 is arranged at the bottom of the material rack 101; the material detector 102 is used to monitor whether there is still material to be sealed, thereby avoiding the problem of idle running of the equipment.

[0024] The sealing and cutting mechanism 4 further comprises sealing and cutting cylinders 401, three sealing and cutting cylinders 401 are fixedly arranged on the top of the equipment away from the pushing mechanism 1, and the general shape formed by the sealing and cutting cylinders 401 is similar to the shape of the product; by controlling the movement of the three sealing and cutting cylinders 401, the protective film of the product after being sealed can be sealed and cut.

[0025] The specific working mode is as follows:

[0026] First round:

[0027] First step: the material detector 102 detects whether there is a product in the material rack 101:

[0028] ① If there is no product in the material rack 101, the machine stops running;

[0029] ② If there is, the machine runs the second step;

[0030] Second step: the pushing mechanism 1 pushes the product to the sealing and cutting mechanism 4 and retreats back, and at the same time, the film feeding mechanism 3 synchronously runs; after the pushing mechanism 1 continues to push the material to the position, the pushing mechanism 1 retreats back;

[0031] Third step: when the pushing mechanism 1 retreats back to a certain distance, the pressing mechanism 2 will press down to press the film, thereby preventing the film from retreating after being sealed and cut; when the pushing product runs next time, the pressing mechanism 2 will be lifted again;

[0032] Fourth step: after the film is pressed, the three cylinders are pressed down to seal and cut, and after the sealing and cutting, the three cylinders are lifted after the sealing and cutting time set by the PLC control system 5;

[0033] The nth+1 round:

[0034] First step: the material detector 102 detects whether there is a product in the material rack 101:

[0035] ① If there is no product in the material rack 101, the machine stops running;

[0036] If there is, the machine runs the second step;

[0037] The second step: when the product pushing mechanism 1 pushes the product to a certain extent, the film pressing mechanism 2 will be lifted, and the film feeding mechanism 3 will run synchronously; the subsequent continues to execute the third step of the first round until there is no product on the product shelf 101.

[0038] By using the PLC control system 5 to control the operation of each mechanism, and when the pushing cylinder works, the pushing force will make the upper and lower films tight and generate tension, so that the swing rod roller 305 is lifted upwards, thereby driving the inductive sheet 306 to separate from the inductor 307; at this time, the upper and lower film feeding motors work, and the film feeding is continuously carried out, so as to prevent the upper and lower films from being torn; until the inductor 307 senses the inductive sheet 306, the upper and lower film feeding motors stop working, and the upper and lower film feeding mechanism 3 stops feeding the film, thereby solving the problem of "current automatic film sealing equipment can only seal the products with small size, smooth surface and regular shape, and some large size and irregular shaped products cannot be completely sealed and the film is damaged" in the background art.

[0039] The above describes the utility model and its implementation mode, which is not limited, and the embodiment shown in the drawings is only one of the embodiments of the utility model, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structure modes and embodiments can be designed without creativity, which should belong to the protection scope of the utility model.
