Description

Technical Field

[0001] This utility model relates to the field of film restoration technology, specifically to an automated film cleaning device. Background Technology

[0002] As an important carrier of cultural heritage, the preservation and restoration of film is of paramount importance. Film restoration processes involve meticulous cleaning, drying, and shaping to remove stains, scratches, bubbles, and other imperfections from the film, restoring its original color and texture as much as possible for long-term preservation.

[0003] Existing technologies have conducted some research on film restoration devices. See patent application number 202311566861.1, which discloses a device for repairing air bubbles in film. This device, during film restoration, first places the film roll onto a first roller, then places the film on a worktable and places one end into a pressing plate and a dryer, connecting the other end to a second roller. At this point, the motor is turned on, causing the second roller to rotate and rewind the film. The film moves under the rewinding action of the second roller, and during this movement, a cleaning device prioritizes cleaning impurities adhering to the film. Simultaneously, the transmission table is activated, causing a perforation plate to move up and down, puncturing air bubbles on the film within the worktable area and injecting restoration fluid into the bubbles, completing the fluid injection. After the film has been filled with restoration fluid, it continues to move to the pressing plate to roll out excess restoration fluid, and then enters the dryer for drying, thus achieving an automatic film restoration effect.

[0004] Therefore, it can be seen that film restoration is achieved through cleaning, bubble repair, and drying. However, in actual operation, manual control often makes it difficult to guarantee the precision of the operation time in each step. Once the time control of any step is deviated, such as impurities not being completely cleaned or drying not being thorough, it will directly affect the quality of the restored film, resulting in poor film restoration results.

[0024] The technical solution of this utility model will be further explained and described below with reference to the accompanying drawings and embodiments, but this utility model is not limited to the embodiments described below.

[0025] Film restoration processes involve meticulous cleaning, drying, and shaping to remove stains, scratches, and air bubbles from the film, restoring its original color and texture as much as possible for long-term preservation. However, in practice, manual control often struggles to guarantee the precision of each step's timing. Any deviation in timing, such as incomplete cleaning or drying, directly impacts the restored film's quality, leading to poor results. This invention aims to provide an automated film cleaning device. By incorporating a PLC control system connected to the unwinding mechanism 1, immersion mechanism 2, spraying mechanism 3, drying mechanism 4, and rewinding mechanism 5, these mechanisms automatically complete a series of operations—film release, immersion, cleaning, drying, and collection—under the precise control of the PLC system.

[0026] Example 1:

[0027] Reference Figure 1 and Figure 2 An automated film cleaning device includes: a PLC control system and an unwinding mechanism 1, an immersion mechanism 2, a spraying mechanism 3, a drying mechanism 4, and a rewinding mechanism 5 connected sequentially along the film cleaning sequence. The PLC control system is connected to the unwinding mechanism 1, the immersion mechanism 2, the spraying mechanism 3, the drying mechanism 4, and the rewinding mechanism 5. The unwinding mechanism 1 releases the film to be cleaned, the immersion mechanism 2 soaks the film to be cleaned, the spraying mechanism 3 cleans the soaked film, the drying mechanism 4 dries the cleaned film, and the rewinding mechanism 5 collects the dried film. The PLC control system controls the operating status of the unwinding mechanism 1, the immersion mechanism 2, the spraying mechanism 3, the drying mechanism 4, and the rewinding mechanism 5.

[0028] Specifically, the PLC control system is model SMART200. During the film cleaning process, the PLC control system is responsible for precisely controlling the working sequence and status of each mechanism, ensuring that every step of the film from unwinding to rewinding proceeds according to the preset program to achieve the best cleaning effect.

[0029] Reference Figure 1 and Figure 2 The unwinding mechanism 1 includes a support plate 11, an unwinding drive 13, an unwinding reel 12, and a first conveying roller 14. The unwinding reel 12 is mounted on the support plate 11, and the film to be cleaned is wound on the unwinding reel 12; the output end of the unwinding drive 13 is coaxially connected to the unwinding reel 12; the first conveying roller 14 is mounted on the support plate 11, and the film to be cleaned passes around the first conveying roller 14 and is connected to the immersion mechanism 2.

[0030] Specifically, the unwind drive 13 is a servo motor, which precisely controls the rotation speed of the unwind reel 12 to ensure that the film to be cleaned is released at a constant speed.

[0031] Reference Figure 1 and Figure 2 The immersion mechanism 2 includes an immersion tank 21, an immersion plate 22, a connecting rod, and a second conveying roller 23. The immersion tank 21 is positioned below the support plate 11; the immersion plate 22 is connected to the support plate 11 via the connecting rod, and the immersion plate 22 extends into the immersion tank 21; the second conveying roller 23 is mounted on the immersion plate 22, and the film to be cleaned on the first conveying roller 14 passes around the second conveying roller 23 and connects to the spraying mechanism 3.

[0032] Specifically, the immersion tank 21 contains a cleaning solution, which submerges the film to be cleaned wound on the second conveyor roller 23. The cleaning solution can be an organic solvent such as n-butanol, ethanol, or acetone. A suitable cleaning solution is used to remove stains and grease from the film. Preferably, n-butanol solution is used, as it effectively removes stains and grease from the film without damaging it.

[0033] Reference Figure 1 and Figure 2 The spraying mechanism 3 includes a spraying assembly and a third conveying roller. The spraying assembly is mounted on the support plate 11; the third conveying roller is mounted inside the spraying assembly, and the film soaked on the second conveying roller 23 bypasses the third conveying roller and connects to the drying mechanism 4.

[0034] Specifically, the spraying assembly is a spraying device known to those skilled in the art, and any configuration capable of cleaning the soaked film is acceptable. Preferably, the spraying assembly employs high-pressure spraying technology, which uses nozzles to evenly spray the cleaning solution onto the film surface, thereby cleaning the soaked film.

[0035] Reference Figure 1 and Figure 2 The drying mechanism 4 includes a drying assembly and a fourth conveyor roller 41. The drying assembly is mounted on the support plate 11; the fourth conveyor roller 41 is mounted inside the drying assembly, and the cleaned film on the third conveyor roller passes around the fourth conveyor roller 41 and connects to the winding mechanism 5.

[0036] Specifically, the drying assembly is a drying device known to those skilled in the art, and any arrangement capable of drying the cleaned film is acceptable. Preferably, the drying assembly uses a hot air circulation mode, where hot air is evenly blown onto the cleaned film via a heater and a fan.

[0037] Reference Figure 1 and Figure 2 The winding mechanism 5 includes a receiving tray 51, a winding drive 52, and a fifth conveying roller 53. The receiving tray 51 is mounted on the support plate 11 and is used to wind the dried film. The output end of the winding drive 52 is coaxially connected to the receiving tray 51. The fifth conveying roller 53 is mounted on the support plate 11, and the dried film on the fourth conveying roller 41 passes around the fifth conveying roller 53 and connects to the receiving tray 51.

[0038] Specifically, the winding drive 52 is a servo motor, which precisely controls the rotation speed of the receiving tray 51 to ensure that the dried film is collected at a constant speed.

[0039] In this embodiment, multiple first conveying rollers 14, second conveying rollers 23, third conveying rollers, fourth conveying rollers 41, and fifth conveying rollers 53 are provided, and each includes two types: tensioning rollers and idler rollers. The operator can flexibly adjust the number and position of tensioning rollers and idler rollers according to the width, thickness, and conveying speed of the film to ensure that the film remains stable and under appropriate tension during the conveying process.

[0040] Example 2:

[0041] Reference Figure 1 and Figure 2 In this embodiment of the automated film cleaning equipment, based on embodiment 1, multiple second conveying rollers 23 are provided, and the multiple second conveying rollers 23 are staggered in the vertical direction.

[0042] Specifically, the multiple second conveying rollers 23 can be arranged in a Z-shape, an S-shape, or a wavy shape along the length of the immersion tank 21. By staggering the multiple second conveying rollers 23 along the height of the immersion tank 21, the film to be cleaned can fully contact the cleaning solution during immersion. Any of these arrangements is acceptable. Preferably, the multiple second conveying rollers 23 are arranged in a Z-shape along the length of the immersion tank 21. The Z-shape increases the contact area between the film to be cleaned and the cleaning solution, while preventing excessive wrinkles and deformation of the film during immersion.

[0043] Example 3:

[0044] Reference Figure 1 In this embodiment of the automated film cleaning equipment, based on embodiment 1, the spraying mechanism 3 is covered by a spraying box 31.

[0045] In this embodiment, the spraying mechanism 3 is covered by a spraying box 31, which facilitates the containment of splashes and harmful gases generated during the spraying process within the spraying box 31, thereby avoiding environmental pollution and protecting the operators.

[0046] Example 4:

[0047] Reference Figure 1 In this embodiment of the automated film cleaning equipment, based on embodiment 1, the drying mechanism 4 is covered by a drying chamber 42.

[0048] In this embodiment, the drying mechanism 4 is covered by a drying chamber 42, which facilitates the sealing of the heat and moisture generated during the drying process within the chamber, preventing the heat from escaping into the working environment and thus improving the drying efficiency.

[0049] The working principle of this automated film cleaning equipment is as follows: First, the film to be cleaned is wound in a coil onto an unwinding reel. Then, the conveying speed of the film to be cleaned and the working sequence and status of each mechanism are set through the PLC control system. After the cleaning equipment is started, the unwinding drive 13 starts working, driving the unwinding reel 12 to rotate, thereby releasing the film to be cleaned. The film to be cleaned first passes around the first conveying roller 14 and enters the immersion tank 21. After entering the immersion tank 21, the film to be cleaned is completely immersed in the cleaning solution under the support of the second conveying roller 23. The soaked film enters the spraying assembly and is cleaned under the support of the third conveying roller. The cleaned film enters the drying assembly and is dried under the support of the fourth conveying roller 41. The dried film is conveyed to the receiving reel 51 under the support of the fifth conveying roller 53. The winding drive 52 drives the receiving reel 51 to rotate, collecting the dried film, and finally completing the cleaning of the film to be cleaned.

[0050] The preferred embodiments of this utility model are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
