[0070] The transmission component 2 further includes a transport rack 35, on which a conveyor belt 36 is arranged for transporting the processed paper-plastic bags;

[0071] The sorting component 3 includes a sorting table 4 that matches the height of the transport rack 35. The sorting table 4 is arranged on one side of the transport rack 35. On both sides of the end of the transport rack 35 close to the sorting table 4, baffles 5 are arranged. On the opposite surfaces of the two baffles 5, first magnetic attraction plates 6 are arranged. A surrounding plate 7 is fixedly installed on the top edge of the sorting table 4. An electric control rotating rod 8 is arranged on the side wall of the surrounding plate 7 at a position aligned with the conveyor belt 36. A partition plate 9 is fixedly installed on the electric control rotating rod 8. A second magnetic attraction plate 10 is fixedly installed in the end area of the partition plate 9. The second magnetic attraction plate 10 and the first magnetic attraction plate 6 are magnetically attracted to each other;

[0072] The electric control rotating rod 8 is electrically connected to a small motor, and the small motor is installed at the bottom of the sorting table 4. A collection box is arranged at each end of the sorting table 4.

[0073] The first embodiment:

[0074] Install the plastic-sealed film roll on the first reel 31, and install the second reel 33 without the plastic-sealed film on the third driving component 34 to ensure that the second reel 33 realizes electric control rotation through the third driving component 34. Then pull a layer of plastic-sealed film from the first reel 31 and wind it around the second reel 33 after passing under the detection rod 24. The first reel 31 and the second reel 33 move simultaneously to ensure the stable operation of the plastic-sealed film. The control end controls the rotating rod assembly 23 to rotate around the rotating motor by sending an instruction. The movement track of the rotating rod assembly 23 is as shown in the appendix Figure 2 As shown, by controlling the pressing amplitude of the rotating rod assembly 23, the distance between the plastic-sealed film and the products placed on the conveyor belt 36 is controlled. Since the shapes and heights of each batch of products are inconsistent, the position of the rotating rod assembly 23 needs to be adjusted for each batch of products to ensure the correct position of the plastic-sealed film. If the position of the plastic-sealed film is too high, the distance between the plastic-sealed film and the paper-plastic bag is large after the paper-plastic bag cutting component 1 cuts down, and it is inconvenient for the heat sealer 21 to operate;

[0075] Ensure that the first reel 31 and the second reel 33 rotate in the same direction to ensure the operation process of the plastic-sealed film;

[0076] Plastic film detection process: The operator places the paper-plastic bag on the conveyor belt 36. The plastic film passes under the paper-plastic bag cutting assembly 1 and covers the paper-plastic bag on the conveyor belt 36. The control end controls the telescopic rod 18 to descend. The descent of the telescopic rod 18 drives the entire drag plate 19 below it to descend. At this time, the cutting knife 37 is in a state of being attached to the side wall of the heat sealer 21. The descent of the drag plate 19 drives the heat sealer 21 to descend. The descent of the heat sealer 21 drives the ejector rod 38 to descend. The ejector rod 38 contacts the plastic film when it descends. The position where the heat sealer 21 descends is set manually, which is the optimal operating position of the heat sealer 21, facilitating the heat sealer 21 to perform heat sealing on the plastic film. Since the bottom of the ejector rod 38 protrudes, the ejector rod 38 presses down the plastic film after contacting it. At this time, the pressure sensor records the pressure value at this time as F1. The control end of the intelligent packaging system sets the pressure value range of the pressure sensor as [F min -F max ,F min is the minimum value that the pressure sensor can detect. If the detected value of the pressure sensor is less than F min it means that the pressing amplitude of the plastic film is too low. F max is the minimum value that the pressure sensor can detect. If the detected value of the pressure sensor is higher than F max it means that the pressing amplitude of the plastic film is too high. Whether the position of the plastic film is too high or too low will affect the sealing between the plastic film and the paper-plastic bag. If F1 is less than F min the operating end controls the rotating rod assembly 23 to rotate and drive the branch rod 22 to rise. The rising of the branch rod 22 drives the detection rod 24 to rise, increasing the height of the plastic film. If F1 is greater than F max the operating end controls the rotating rod assembly 23 to rotate and drive the branch rod 22 to descend. The descent of the branch rod 22 drives the detection rod 24 to descend, reducing the height of the plastic film. The ejector rod 38 always contacts the plastic film and performs pressure detection on the plastic film. Combined with the movement of the rotating rod assembly 23, it ensures that the plastic film is always at an appropriate height, replacing the process of manually adjusting the plastic film;

[0077] After the position adjustment of the plastic film is completed, the conveyor belt 36 starts. At the same time, the telescopic rod 18 drives the heat sealer 21 to move upward by a set value. The telescopic rod 18 descends once every H time according to the set frequency and cycles through the up-down process. Each time it descends, the heat sealer 21 operates once. The heat sealer 21 is cuboid-shaped and heat seals the plastic film below, sealing the bonding edge of the plastic film and the paper-plastic bag. During the heat sealing process of the heat sealer 21, the cutting knife 37 on its side wall bends and forms an obtuse angle with the heat sealer 21. At this time, the cutting knife 37 can cut the plastic film. Since the cutting knife 37 is installed outside the heat sealer 21, the cutting line of the plastic film cut by the cutting knife 37 is outside the heat sealer 21, ensuring that the heat seal of the plastic film and the paper-plastic bag is within and the cutting line is inside. At this time, the plastic film goes through two processes of heat sealing and the first cutting and is transported further by the conveyor belt 36. When the processed paper-plastic bag is transported below the detection rod 24 (at this time, the paper-plastic bag and the plastic film are not completely separated), the suction holes 25 on the detection rod 24 adsorb the plastic film on the detection rod 24. At this time, the plastic film forms a strong adhesion with the surface of the detection rod 24 due to the suction force. Since the paper-plastic bag is heat-sealed to the plastic film at this time, the first reel 31 and the second reel 33 rotate simultaneously to drive the paper-plastic bag to move. The movement of the paper-plastic bag forms an extrusion with the detection rod 24. If the heat-sealed edge between the paper-plastic bag and the plastic film is airtight, the air flow sensor has no detected value, and the intelligent packaging system drives the detection rod 24 to rotate on the branch rod 22. The rotation of the detection rod 24 on the branch rod 22 drives the transverse cutting knife 27 to rotate. The rotation of the transverse cutting knife 27 cuts the remaining side of the plastic film. This cutting is divided into two cutting processes, attached Figure 11 The attached shows the paper-plastic bag and the plastic film after being cut by the cutting knife 37, attached Figure 12 The attached shows the paper-plastic bag and the plastic film after being cut by the first transverse cutting knife 27, attached Figure 13 The attached shows the paper-plastic bag and the plastic film after being cut by the second transverse cutting knife 27. After each rotation of the detection rod 24, it immediately resets. After two rotations, the remaining plastic film is cut off. The plastic film heat-sealed on the paper-plastic bag loses its connection with the plastic film roll, and the paper-plastic bag drops onto the conveyor belt 36 along with it and moves to the sorting table 4 via the conveyor belt 36. If the heat-sealed edge between the paper-plastic bag and the plastic film leaks air, the air flow sensor detects a value, and the intelligent packaging system does not drive the detection rod 24 to rotate. The unqualified paper-plastic bags are rolled onto the second reel 33 together with the remaining plastic film. Thus, the purpose of automatically distinguishing qualified paper-plastic bags is achieved, and the qualified and unqualified paper-plastic bags are automatically separated, improving the processing quality of the paper-plastic bags;

[0078] The suction holes 25 extract air and discharge it through the exhaust holes 26, forming a suction force to adsorb the plastic film on the detection rod 24.

[0079] Second Embodiment:

[0080] The intelligent packaging system sets the movement frequency of the electric control rotating rod 8 to G. Every G time period, the electric control rotating rod 8 drives the partition plate 9 to rotate once. Each time the partition plate 9 rotates, it will select one side of the transport rack 35. Each time the partition plate 9 only adsorbs to one first magnetic attraction plate 6. By controlling the movement of the partition plate 9 in the above manner, it is transferred out in batches from both ends of the sorting table 4, leaving time for the staff to replace the collection box at the unused end of the sorting table 4.

[0081] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0082] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
