[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-Figure 8 A aging device for producing plastic packaging bags is shown, comprising an aging box 1, an auxiliary aging mechanism and an aging intelligent controller 2. A aging component is installed in the aging box 1. The aging component is a common aging component in the existing aging box, which is used to control the inner cavity of the aging box 1 to maintain a constant temperature and humidity. It is a prior art well known to those skilled in the art, and the specific working principle and specific structure thereof are not repeated in the present application. Sealed doors are hinged at both ends of the aging box 1, and guide rails 8 are installed on both sides of the inner wall of the aging box 1 for conveying a raw material roll 6, such as Figure 4As shown, one side of the raw material is covered with a ventilation pad paper 26 and rolled up on a winding roller 7 to form a raw material roll 6. The raw material roll 6 to be matured is input through a material guide rail 8, and the raw material roll 6 that has completed maturation is discharged through the material guide rail 8, which is convenient for loading and unloading operations. By arranging the ventilation pad paper 26 in the raw material roll 6, the permeability between each layer of the raw material after winding is increased, which facilitates the hot air in the maturation box 1 to pass through the rolled raw material roll 6, thereby increasing its maturation uniformity and maturation efficiency.

[0021] It is worth mentioning that see Figure 3-Figure 5 and Figure 7 The auxiliary aging mechanism includes multiple auxiliary components arranged on the upper and lower sides of the guide rail 8, gas circulation components matched with the auxiliary components, and transfer blocks 15 corresponding to the auxiliary components. Multiple auxiliary components are arranged to assist in aging multiple rolls of raw material rolls 6 to improve aging efficiency, and multiple auxiliary components are arranged on the upper and lower sides of the guide rail 8 to improve the utilization rate of the space in the aging box 1. The transfer block 15 is vertically slidably connected to the guide rail 8. A lifting component 16 is installed on one side of the transfer block 15 for automatically driving the transfer block 15 to move vertically. An electromagnet 1 is installed on the transfer block 15. When the transfer block 15 contacts the winding roller 7 on the raw material roll 6, the winding roller 7 and the transfer block 15 are locked by the electromagnet 1, and the lifting component 16 is used to synchronously control the up and down movement of the raw material roll 6 to move the raw material roll 6 to the upper or lower auxiliary component for loading. Similarly, the matured raw material roll 6 is moved from the auxiliary component to the guide rail 8 for unloading. Each The auxiliary components include side air guide plates 9 arranged on both sides of the inner cavity of the ripening box body 1, a plurality of through holes opened on each side air guide plate 9 close to the inner cavity of the ripening box body 1, and a telescopic member 14 installed on the side of the side air guide plate 9 away from the inner cavity of the ripening box body 1. A positioning cylinder 11 fixed to the side wall of the ripening box body 1 is inserted in the middle of each side air guide plate 9. A locking mechanism connected to the winding roller 7 is arranged on the positioning cylinder 11, which is used to control the locking of the winding roller 7 and the positioning cylinder 11. A proximity switch 12 is installed at the end of the positioning cylinder 11. The proximity switch 12 can detect whether the winding roller 7 is installed in place. When the winding roller 7 moves to the positioning cylinder 11 on the side air guide plate 9, the locking mechanism automatically locks the positioning cylinder 11 and the winding roller 7 to fix the position of the raw material roll 6. At this time, the corresponding side air guide plate 9 is pushed to the two ends of the raw material roll 6 by the telescopic member 14 located on both sides of the raw material roll 6, so that the inner cavity of the side air guide plates 9 at both ends fits with the two ends of the raw material roll 6.

[0022] In addition, the gas circulation component includes a return air pipe 3 connected to one side of the side air guide plate 9, and an exhaust pipe 4 connected to the other side air guide plate 9. The output end of the return air pipe 3 and the input end of the exhaust pipe 4 are both connected to the inner cavity of the aging box 1. A circulation air pump 5 is installed on each exhaust pipe 4. A flow sensor 27 is installed in the inner cavity of each side air guide plate 9 corresponding to the exhaust pipe 4. When the circulation air pump 5 works, it sucks the hot air from the inner cavity of the aging box 1 into the exhaust pipe 4 and discharges it into the inner cavity of the corresponding side air guide plate 9. At this time, the hot air is ventilated. The hot air is input through one end of the raw material roll 6 and output through the other end. The output hot air is introduced into the return air pipe 3 through the side air guide plate 9 on the other side, and is re-input into the inner cavity of the ripening box 1 through the output end of the return air pipe 3, and the hot air is circulated into the end of the raw material roll 6, so that each layer of raw materials can be fully ripened, the ripening efficiency is improved, and the fluidity of the air in the inner cavity of the ripening box 1 is increased during the circulation ripening process, and the uniformity of the hot air in the inner cavity of the ripening box 1 is further increased, so that the raw material rolls 6 located on the upper and lower sides can be evenly ripened.

[0023] In the present embodiment, the ripening intelligent controller 2 is installed on the ripening box 1, and the ripening intelligent controller 2 is provided with a loading button, a loading and unloading module, an auxiliary ripening module and a reminder module. The loading and unloading modules are respectively electrically connected to the loading button, the auxiliary ripening module, the reminder module, the lifting component 16 and the electromagnet 1, and the auxiliary ripening module is respectively electrically connected to the circulating air pump 5, the proximity switch 12, the telescopic part 14 and the flow sensor 27. When the raw material roll 6 to be ripened needs to be loaded, the loading button is pressed to send a loading signal to the loading and unloading module, and the loading and unloading module controls the corresponding lifting component 16 to work and move the transfer block 15 to the upper surface of the protruding guide rail 8. At this time, the raw material roll 6 is input through the guide rail 8 and moves to the corresponding transfer block 15, and the winding roller 7 is adsorbed and fixed by the electromagnet 1 installed on the transfer block 15. By controlling the lifting component 16 to work The transfer block 15 is moved up or down together with the raw material roll 6 to the corresponding side air guide plate 9. At this time, the proximity switch 12 on the side air guide plate 9 receives the position signal of the winding roller 7 and sends it to the auxiliary ripening module. The auxiliary ripening module determines that the winding roller 7 has been installed in place, and the positioning cylinder 11 locks the winding roller 7. The auxiliary ripening module sends an installation signal to the loading and unloading module. The loading and unloading module controls the electromagnet to cut off the power, releases the lock on the winding roller 7, and controls the lifting component 16 to reset the transfer block 15 to a state where the top surface of the transfer block 15 is flush with the top surface of the guide rail 8, so that the raw material roll 6 loaded and unloaded through the guide rail 8 can roll smoothly along its upper surface, and the auxiliary ripening module controls the telescopic part 14 to work to push the side air guide plates 9 on both sides to fit the two ends of the raw material roll 6, and controls the circulating air pump 5 to work to input hot air circulation into the end of the raw material roll 6; When unloading is required, hot air is introduced into the side air guide plate 9 through the exhaust pipe 4, and flows into the end of the raw material roll 6 through the side air guide plate 9. At this time, the amount of hot air flowing into each side air guide plate 9 is recorded by the flow sensor 27 and fed back to the auxiliary maturation module. When the auxiliary maturation module determines that the amount of hot air flowing through reaches the preset hot air amount (the auxiliary maturation module is preset with the hot air amount required for maturation of each model of raw material roll 6), the auxiliary maturation module determines that the corresponding raw material roll 6 is fully maturated, and controls the corresponding circulating air pump 5 to stop working and the telescopic part 14 to reset, moves the side air guide plate 9 to its original position, and sends an unloading signal to the loading and unloading module. The loading and unloading module controls the corresponding The lifting component 16 works to move the transfer block 15 to the corresponding raw material roll 6, and controls the electromagnet to work to adsorb and lock the winding roller 7, and moves the transfer block 15 together with the raw material roll 6 to the guide rail 8. At this time, the electromagnet is controlled to cut off the power to disengage the lock on the winding roller 7, and the transfer block 15 moves down to be flush with the top surface of the guide rail 8. The winding roller 7 that is separated from the transfer block 15 rolls along the guide rail 8 to unload the material. At the same time, the loading and unloading module sends a reminder signal to the reminder module, and the reminder module sends an audible and visual reminder to remind the staff that the raw material roll 6 has been matured and can be taken out as soon as possible, thereby achieving the purpose of automatic loading and unloading and cyclic maturation, and improving the maturation efficiency and quality of the raw materials.

[0024] See also Figure 7 and Figure 8 The locking mechanism includes a docking rod 17 and an electromagnet 23 plugged into the end of the winding roller 7. A return spring is installed between the inner side of the docking rod 17 and the inner cavity of the winding roller 7. A docking hole 13 matching the docking rod 17 is opened in the middle of the positioning cylinder 11. The electromagnet 23 is installed in the docking hole 13. The electromagnet 23 is electrically connected to the auxiliary ripening module. When the winding roller 7 is moved to the corresponding positioning cylinder 11, the auxiliary ripening module receives a signal that the winding roller 7 has been installed in place through the proximity switch 12, and the auxiliary ripening module controls the electric When magnet 23 is energized, the docking rod 17 is made of ferromagnetic metal. When electromagnet 23 is energized, it produces a magnetic attraction on the docking rod 17, moves the docking rod 17 and inserts it into the docking hole 13, thereby limiting the up and down movement of the winding roller 7 and locking the winding roller 7. When unlocking, the magnetic attraction of the docking rod 17 is released by controlling the electromagnet 23 to be de-energized, and the elastic force of the reset spring is used to control the docking rod 17 to be disengaged from the docking hole 13, thereby releasing the lock on the winding roller 7, which is convenient for automatically controlling the locking of the winding roller 7 and the positioning cylinder 11.

[0025] In this embodiment, the output end of the exhaust pipe 4 is connected to the corresponding side air guide plate 9, the input end of the exhaust pipe 4 is connected to the upper part of the inner cavity of the maturation box 1, the input end of the return pipe 3 is connected to the corresponding side air guide plate 9, and the output end of the return pipe 3 is connected to the lower part of the inner cavity of the maturation box 1. The circulating air pump 5 works to suck the hot air located at the upper part of the inner cavity of the maturation box 1 into the exhaust pipe 4, and discharges it into the return pipe 3 through the side air guide plate 9 and the raw material roll 6, and re-inputs the hot air into the bottom of the inner cavity of the maturation box 1 through the return pipe 3. In the process of circulating and maturing the raw material roll 6, the hot air at the top and bottom of the inner cavity of the maturation box 1 is circulated alternately, which not only increases the fluidity of the air in the inner cavity of the maturation box 1, but also further increases the uniformity of the hot air in the inner cavity of the maturation box 1, so that the raw material rolls 6 located on the upper and lower sides can be evenly matured.

[0026] Also, see Figure 5 , a side of the transfer block 15 close to the output end of the guide rail 8 is provided with an arc-shaped concave surface matching the side of the winding roller 7, and an electromagnet is installed on the arc-shaped concave surface of the transfer block 15. The top of the transfer block 15 is a horizontal structure, and the arc-shaped concave surface is convenient for limiting the winding roller 7, and the electromagnet is used to lock the winding roller 7 with the arc-shaped surface on the transfer block 15 to improve the locking stability. In addition, the upper and lower protruding ends of the arc-shaped concave surface of the transfer block 15 are made of rubber elastic material, and the corresponding parts of the guide rail 8 and the transfer block 15 are made of elastic rubber material. When the transfer block 15 is separated from the After the winding roller 7 is adsorbed, when the transfer block 15 moves down to the bottom of the guide rail 8, the elastic part of the guide rail 8 can limit the winding roller 7, so that the downwardly moved transfer block 15 and the winding roller 7 can be smoothly separated. Both ends of the guide rail 8 are provided with inclined blocks, the guide rail 8 is inclined, and the end of the feed side of the guide rail 8 is higher than the end of the discharge side. When the raw material roll 6 is moved onto the guide rail 8, the winding roller 7 on the raw material roll 6 moves along the inclined guide rail 8 and moves from the loading end of the guide rail 8 to the discharge end, which is convenient for loading and unloading the raw material roll 6.

[0027] The second implementation method: Figure 5 and Figure 7-10The illustrated embodiment shows a aging device for producing plastic packaging bags. Different from the first embodiment, the lifting assembly 16 includes a telescopic member 18 installed at the bottom of the inner cavity of the aging box 1, a mounting seat 19 installed at the output end of the telescopic member 18, and a threaded sleeve 22 connected to the transfer block 15. The threaded sleeve 22 is vertically slidably connected to the mounting seat 19. A rotating member 20 is installed on the mounting seat 19. A screw 21 threadedly connected to the threaded sleeve 22 is installed at the output end of the rotating member 20. The position of the mounting seat 19 can be adjusted by telescoping the telescopic member 18, and the upper and lower positions of the transfer block 15 can be adjusted synchronously, so that the top of the transfer block 15 is controlled to be flush with the top of the guide rail 8, so that the winding roller 7 can smoothly roll along the upper surface of the guide rail 8. The loading and unloading modules are electrically connected to the telescopic member 18 and the rotating member 20 respectively. When the loading or unloading signal is received, the telescopic part 218 and the rotating part 20 are controlled to work. When the transfer block 15 needs to be moved up to the top side air guide plate 9, the telescopic part 218 is controlled to extend and the rotating part 20 is controlled to work. The rotating part 20 drives the threaded sleeve 22 and the transfer block 15 to move up synchronously, thereby moving the transfer block 15 to the corresponding side air guide plate 9; when the transfer block 15 needs to be moved down to the bottom side air guide plate 9, the telescopic part 218 is controlled to be shortened and the rotating part 20 is controlled to rotate in the opposite direction. The rotating part 20 drives the threaded sleeve 22 and the transfer block 15 to move down synchronously, thereby moving the transfer block 15 to the corresponding side air guide plate 9 at the bottom, thereby realizing flexible control of the position of the transfer block 15, and when the transfer block 15 is reset to the top and flush with the guide rail 8, the lifting assembly 16 does not affect the normal rolling of the winding roller 7 along the guide rail 8.

[0028] It is worth mentioning that see Figure 7-Figure 9, each side air guide plate 9 is provided with an adaptive component, the adaptive component includes a plurality of air guide heads 10 plugged into the through holes on the side air guide plate 9, a blind hole is provided on the air guide head 10, and a plurality of side through holes 24 are provided on the side surface of one end of each air guide head 10 close to the inner cavity of the side air guide plate 9. Due to the different models of the raw material roll 6, there are certain differences in the diameters of each roll of raw material roll 6. When the end surface of the raw material roll 6 cannot completely cover the through holes on the side air guide plate 9, the hot air discharged from the side air guide plate 9 will be discharged through the exposed through holes, resulting in less hot air passing through the end surface of the raw material roll 6, affecting its maturation efficiency. Therefore, by setting an adaptive component, when the side air guide plate 9 is controlled to be close to the end of the raw material roll 6, the air guide head 10 in contact with the end of the raw material roll 6 will be inserted into the inner cavity of the side air guide plate 9. At this time, the side through holes 24 located on the side of the air guide head 10 are exposed and connected to the inner cavity of the side air guide plate 9 , the hot air enters the inner cavity of the air guide head 10 through the side through holes 24, and is discharged through the end of the air guide head 10 into the end of the raw material roll 6; the air guide head 10 that is not in contact with the end of the raw material roll 6 remains in place, and at this time, the side through holes 24 on the side of the corresponding air guide head 10 are blocked by the outer wall of the side air guide plate 9, and the hot air cannot enter the corresponding air guide head 10; therefore, the hot air in the inner cavity of the side air guide plate 9 can better enter the end of the raw material roll 6 and is not easy to leak, and can control the hot air to circulate better and pass through each compartment of the raw material roll 6, thereby improving the ripening quality and efficiency. A magnet 25 is installed at one end of the air guide head 10 close to the inner cavity of the side air guide plate 9, and the side air guide plate 9 is made of ferromagnetic metal. When the side air guide plate 9 is out of contact with the end of the raw material roll 6, the magnetic attraction of the magnet 25 controls the air guide head 10 to reset, so as to facilitate the next ripening operation with the end of the raw material roll 6.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
