Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figures 1-7 As shown, a packaging film processing dryer according to one embodiment of the present invention includes a main body mechanism 1 and a cleaning and drying mechanism 2. The main body mechanism 1 includes a pair of mounting plates 11, a film feeding roller 12 and a film receiving roller 13. The pair of mounting plates 11 are arranged opposite to each other, and the film feeding roller 12 and the film receiving roller 13 are respectively mounted between the pair of mounting plates 11 in a rotatable manner. The cleaning and drying mechanism 2 includes a cleaning medium conveying pipe 21, a first drying medium conveying pipe 23, and a second drying medium conveying pipe 25. The cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25 are all installed on the mounting plate 11 in a through manner. The cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25 are sequentially installed between the film feeding roller 12 and the film receiving roller 13. Multiple first nozzles 22 are installed at equal intervals on the upper and lower conveying pipes of the cleaning medium conveying pipe 21. Multiple second nozzles 24 are installed at equal intervals on the upper and lower conveying pipes of the first drying medium conveying pipe 23. Multiple third nozzles 26 are installed at equal intervals on the upper and lower conveying pipes of the second drying medium conveying pipe 25.

[0031] The operating principle of this packaging film processing dryer is as follows: the processed packaging film, wound onto the feeding roller 12, is installed between a pair of mounting plates 11. The packaging film then passes sequentially through the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25, and is wound onto the take-up roller 13. Rotating the take-up roller 13 drives the feeding roller 12 to rotate, causing the packaging film to move between the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25. As the packaging film moves, cleaning liquid atomized and sprayed through multiple first nozzles 22 washes the upper and lower surfaces of the packaging film. The rinsing process cleans the impurities on the upper and lower surfaces of the packaging film, removing particulate impurities that adhere to the film due to static electricity, while preventing damage to the film surface. As the cleaned packaging film moves within the first drying medium conveying pipe 23 and the second drying medium conveying pipe 25, multiple second nozzles 24 and multiple second drying medium conveying pipes 25 spray drying gas onto the upper and lower surfaces of the packaging film, allowing the moisture on the film to be dried a second time via air knives. This ensures that the surface of the cleaned packaging film is dry, facilitating subsequent packaging and storage operations.

[0032] Preferably, the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25 are all configured as "U"-shaped pipes to facilitate cleaning and drying of the upper and lower surfaces of the packaging film.

[0033] like Figure 3 and Figure 5 As shown, the main body mechanism 1 also includes a mounting assembly, which includes a rotating shaft 14, a socket frame 15, and a socket rod 16. The rotating shaft 14 is rotatably mounted on the mounting plate 11.

[0034] like Figure 2 and Figure 3 As shown, a low-speed motor is installed on the side wall of the mounting plate 11, and the rotating shaft of the low-speed motor is connected to the rotating shaft 14 at one end of the film take-up roller 13, so that the film take-up roller 13 is driven to rotate by the rotation of the low-speed motor.

[0035] like Figure 3 and Figure 5 As shown, the connecting rod 16 is fixedly connected to the front and rear ends of the film feeding roller 12 and the film receiving roller 13. The connecting frame 15 is fixed on one end of the rotating shaft 14, which is located inside the mounting plate 11. The connecting rod 16 is sleeved inside the connecting frame 15. Limiting screws 17 are installed on the connecting frame 15 and the connecting rod 16. The connecting rod 16 is fixed inside the connecting frame 15 by the limiting screws 17, so that the rotation of the rotating shaft 14 can drive the connecting rod 16 to rotate, thereby driving the film receiving roller 13 to rotate. At the same time, the connecting rod 16 can be easily removed from the connecting frame 15, so as to facilitate the replacement of the cleaned packaging film.

[0036] like Figure 4 and Figure 7 As shown, the first nozzle 22, the second nozzle 24, and the third nozzle 26 are all inclined towards the film feeding roller 12. The inclination angle of the first nozzle 22, the second nozzle 24, and the third nozzle 26 is set to 45 degrees. This allows the packaging film to move between the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25. The first nozzle 22, the second nozzle 24, and the third nozzle 26 atomize the medium, improving the treatment effect on the packaging film. The height of the first drying medium conveying pipe 23 is higher than the height of the cleaning medium conveying pipe 21, so that the height of the air knife treating the packaging film is higher than the height of the cleaning packaging film, improving the air drying effect on the upper surface of the packaging film.

[0037] like Figure 3 and Figure 6 As shown, the cleaning and drying mechanism 2 also includes a media conveying assembly, which includes a gas-liquid mixing device 27, a cleaning liquid conveying pipe 28, and a first gas conveying pipe 29. The outlet of the gas-liquid mixing device 27 is connected to the inlet of the cleaning media conveying pipe 21, so that the cleaning medium processed by the gas-liquid mixing device 27 enters the cleaning media conveying pipe 21.

[0038] like Figure 3 and Figure 6 As shown, the cleaning liquid delivery pipe 28 is installed at the inlet of the gas-liquid mixing device 27, and the first gas delivery pipe 29 is installed on the side wall of the cleaning liquid delivery pipe 28. Both the cleaning liquid delivery pipe 28 and the first gas delivery pipe 29 are equipped with regulating valves. The cleaning liquid delivery pipe 28 delivers the cleaning liquid to the gas-liquid mixing device 27, and the first gas delivery pipe 29 delivers the drying gas to the gas-liquid mixing device 27. This allows the cleaning liquid and drying gas to be mixed into a two-fluid medium within the gas-liquid mixing device 27 before being delivered to the cleaning medium delivery pipe 21, thereby effectively improving the cleaning effect on the packaging film.

[0039] like Figure 3 and Figure 6 As shown, the media delivery assembly also includes a second gas delivery pipe 210 and an inlet pipe 211. The second gas delivery pipe 210 is connected to the inlets of the first drying media delivery pipe 23 and the second drying media delivery pipe 25. The inlet pipe 211 is installed at the inlet end of the first gas delivery pipe 29 and the second gas delivery pipe 210. The inlet pipe 211 delivers drying gas to the first gas delivery pipe 29 and the second gas delivery pipe 210. The second gas delivery pipe 210 delivers drying gas to the first nozzle 22 and the second nozzle 24 for drying the packaging film.

[0040] like Figures 2-4As shown, the cleaning and drying mechanism 2 also includes a pair of pressure rods 212 symmetrically fixed on a pair of mounting plates 11. The height of the pair of pressure rods 212 is lower than the height of the film feeding roller 12. The pair of pressure rods 212 press down the front and rear ends of the packaging film located upstream of the cleaning medium conveying pipe 21, so that the cleaning liquid after the cleaning medium conveying pipe 21 cleans the packaging film flows down through the two ends pressed down by the pressure rods 212, avoiding the accumulation of cleaning liquid on the packaging film.

[0041] like Figure 4 As shown, the cleaning and drying mechanism 2 also includes a guide rod 213 fixed between a pair of mounting plates 11. The guide rod 213 is disposed between the cleaning medium conveying pipe 21 and the first drying medium conveying pipe 23, and the height of the guide rod 213 is higher than the height of the pressure rod 212. The packaging film cleaned by the cleaning medium conveying pipe 21 is guided by the guide rod 213, so that the height of the packaging film when moving in the first drying medium conveying pipe 23 and the second drying medium conveying pipe 25 is higher than the height when moving in the cleaning medium conveying pipe 21.

[0042] like Figures 1-4 As shown, the cleaning and drying mechanism 2 also includes a water storage frame 214 disposed at the bottom of a pair of mounting plates 11, and the water storage frame 214 is disposed at the bottom of the pressure rod 212 and the guide rod 213. The cleaning liquid after cleaning the packaging film is recycled through the water storage frame 214 for reuse.

[0043] In use, the processed packaging film wound on the film feeding roller 12 is installed between a pair of mounting plates 11 via the mounting assembly. The packaging film then passes sequentially through the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25, and is wound onto the take-up roller 13. A low-speed motor drives the take-up roller 13 to rotate, which in turn drives the film feeding roller 12 to rotate, causing the packaging film to move between the cleaning medium conveying pipe 21, the first drying medium conveying pipe 23, and the second drying medium conveying pipe 25. As the packaging film moves, the dual-fluid cleaning medium conveyed into the cleaning medium conveying pipe 21 by the media conveying assembly is atomized and sprayed onto the packaging film through multiple first nozzles 22. The upper and lower surfaces of the packaging film are rinsed to remove impurities through a dual-fluid medium rinsing process. This removes particulate impurities that adhere to the packaging film due to static electricity, while preventing damage to the film surface. As the cleaned packaging film moves within the first drying medium conveying pipe 23 and the second drying medium conveying pipe 25, multiple second nozzles 24 and multiple second drying medium conveying pipes 25 spray drying gas onto the upper and lower surfaces of the packaging film. This allows the moisture on the packaging film to be dried a second time through the air knife, achieving a drying treatment of the film surface moisture and ensuring that the cleaned packaging film surface is dry for subsequent packaging and storage operations.
