Description

Technical Field

[0001] This invention relates to the field of release film cleaning technology, and more particularly to a steam cleaning device for the surface of release film used in release film processing. Background Technology

[0002] Release film, as a functional film with precise peeling properties, is widely used in high-end industrial fields such as electronic component packaging, tape production, and copper clad laminate manufacturing. Its surface cleanliness, flatness, and coating integrity directly determine the processing accuracy and reliability of downstream products. During the roll-to-roll production of release film, dust particles and other contaminants from the production environment can easily remain on the film surface after roll formation. If it is not effectively cleaned, it will lead to problems such as adhesion failure and peeling force fluctuations during subsequent use of the release film, which will seriously affect the yield of downstream products.

[0003] To address the cleaning problem of roll-to-roll release films, various cleaning solutions have been developed in the existing technology, but all of them have significant drawbacks: For the vertical roll-to-roll cleaning solution: after placing the roll of release film vertically, it is loosened by unwinding the release film in the opposite direction of the winding direction and using vibration, and then cleaned with steam or other media; however, this solution has a fatal flaw: in the vertical state, the loosened film lacks effective support and is prone to falling and piling up due to its own weight, resulting in irreversible wrinkles at the bottom of the film and damaging the flatness of the film surface; at the same time, the uneven distribution of the gaps between the film layers when loosened vertically, the inner layer of the film is squeezed and cannot be fully loosened, the steam cannot penetrate effectively, forming cleaning blind spots and resulting in poor cleaning effect; For the unfolding cleaning solution: After the roll of release film is fully unfolded, it is cleaned by brushing, chemical solvent spraying or high-pressure water washing, and then rewound. This solution is cumbersome, the unfolding and rewinding process takes a long time, and the cleaning efficiency is low. Moreover, the unfolded film is thin and flexible, and the surface silicone oil coating is easily scratched by physical structures such as brushes. Chemical solvents may react with the coating, causing abnormal release force. After high-pressure water washing, the condensate residue can easily form water stains, all of which will cause secondary damage to the film. In summary, existing release film roll cleaning technologies generally suffer from technical pain points such as "the film is prone to wrinkling and the cleaning efficiency is low". Therefore, developing a steam cleaning device for the surface of roll release films that can avoid the film from sagging and wrinkling and has high cleaning efficiency has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to address the problem that when cleaning in a vertical position, the loosened membrane lacks effective support and is prone to falling and accumulating due to its own weight, resulting in irreversible wrinkles at the bottom of the membrane and damaging the flatness of the membrane surface. Therefore, this invention proposes a steam cleaning device for the surface of release membranes in release membrane processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steam cleaning device for the surface of release film for release film processing includes a mounting frame, on which vertical boxes are mounted. Each of the two vertical boxes is equipped with a column head unit for mounting rolled release film. The column head unit includes two bearing seats and a shaft column rotatably connected in the bearing seats. The rolled release film is suspended between the two vertical boxes by a stepped column assembled at the end of the shaft column. One of the vertical boxes is equipped with a geared motor whose output end is connected to one of the shaft columns. The roll release film suspended between the two vertical boxes is rotated counterclockwise under the control of the geared motor so as to loosen the rolled release film. A steam generating unit is installed at the bottom of the mounting frame. The steam generating unit includes a steam generator. The steam generated by the steam generator comes into contact with the loose release membrane surface through a steam guide installed inside the vertical box, so as to clean the membrane surface.

[0006] As a further description of the above technical solution: The other vertical box is equipped with a first electro-hydraulic rod, one end of which passes through the vertical box and is connected to a mounting plate. The two bearing seats are respectively fixed to one of the vertical boxes and the mounting plate.

[0007] As a further description of the above technical solution: Friction blocks are inserted into the outer wall of the stepped column through slots. On both sides of the friction blocks, first springs with ends connected to the inner wall of the stepped column are installed through support blocks. A screw is rotatably connected inside the stepped column. Multiple three-sloping seats adapted to the friction blocks are threaded on the outer surface of the screw. A first motor with an output end connected to the screw is installed at one end of the stepped column.

[0008] As a further description of the above technical solution: The steam guide includes a steam inlet hood fixed inside the vertical box, a guide hood fixedly connected to one side of the steam inlet hood, a steam outlet hole opened on the inner wall of the guide hood, and a three-way solenoid valve installed at the output end of the steam generator through a connecting pipe. Two ends of the three-way solenoid valve are respectively connected to the steam inlet hood through a delivery pipe.

[0009] As a further description of the above technical solution: The mounting frame is also equipped with a positioning unit, which includes a base fixed to the inside of the box. A fixed support is installed at one end of the upper surface of the base. A movable support is slidably connected to the upper surface of the base via a slide rail. A second electro-hydraulic rod is installed on the lower surface of the base, with one end connected to the movable support.

[0010] As a further description of the above technical solution: Both the fixed support and the moving support are rotatably connected to a connecting ring. Multiple bidirectional telescopic rods are installed on the inner sides of the two connecting rings. A third electro-hydraulic rod is fixed in the middle of the bidirectional telescopic rod. One end of the third electro-hydraulic rod passes through the bidirectional telescopic rod and is rotatably connected to a connector via a U-shaped seat. A pressure rod is fixed at the bottom end of the connector.

[0011] As a further description of the above technical solution: Multiple positioning holes are provided on both sides of the connector. A hemispherical column is connected to the positioning hole by a second spring. Multiple limiting holes arranged in a circular array are provided on both sides of the U-shaped seat. The hemispherical column is engaged in the corresponding limiting hole, so that the position of the pressure rod is fixed.

[0012] As a further description of the above technical solution: A second motor is mounted on one side of the fixed support base via a bracket, and an L-shaped adjusting rod is mounted on the output end of the second motor.

[0013] As a further description of the above technical solution: A fourth electro-hydraulic rod is mounted on the outer wall of each of the two connecting rings via a base. A limiting post is mounted on one end of the fourth electro-hydraulic rod. Multiple limiting holes that are arranged in a ring array and adapted to the limiting post are opened on the outer wall of the shaft post.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. By using the column head unit, the membrane is prevented from wrinkling and being damaged after loosening, ensuring the flatness of the membrane surface. The roll release membrane is horizontally suspended by the vertical box on the mounting frame in conjunction with the column head unit, replacing the vertical placement method. Then, the membrane roll is loosened by driving the reduction motor to rotate counterclockwise, which completely solves the problem of accumulation and wrinkling caused by gravity falling after the membrane is loosened in the vertical state, and protects the flatness of the membrane surface and the integrity of the coating to the greatest extent. Furthermore, the stepped columns adopt a stepped structure, and each step position is equipped with a friction block. In conjunction with the linkage structure of the first motor, screw, and three inclined plane seat, the friction blocks can be driven to push against the inner wall of the roll to achieve a firm fixation of rolls with different inner diameters. At the same time, the first electric hydraulic rod drives the mounting plate and guide rod to move, which can adjust the distance between the two stepped columns to adapt to roll release films of different lengths, significantly improving versatility.

[0015] 2. The positioning unit achieves comprehensive cleaning without blind spots and ensures thorough cleaning. The positioning unit's bidirectional telescopic rod, connecting ring, fourth electro-hydraulic rod, and limiting post, along with the limiting hole on the shaft, allow the membrane roll to rotate 180°, causing the initially bonded upper membrane to shift downwards and naturally loosen. Combined with the steam delivery from the steam guide, steam evenly penetrates all membrane layer gaps, solving the cleaning blind spot problem inherent in traditional roll-to-roll cleaning. Furthermore, the unidirectional steam flow design, with steam entering from one end of the membrane roll and exiting from the other, further enhances contaminant removal efficiency. After cleaning, the pressure rod is tilted by driving the L-shaped adjustment rod. The tilting force guides the condensate on the film surface to flow to one end and be discharged, avoiding the formation of water stains or the growth of microorganisms by condensate residue, and ensuring the stable performance of the release film coating.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 - Figure 12 As shown, the present invention provides: A steam cleaning device for the surface of release film for release film processing includes a mounting frame 10, on which two vertical boxes 11 are mounted. Each vertical box 11 is equipped with a column head unit 20 for mounting rolls of release film. The column head unit 20 includes two bearing seats and a shaft column 21 rotatably connected in the bearing seats. The rolls of release film are suspended between the two vertical boxes 11 by a stepped column 22 mounted on the end of the shaft column 21. One of the upright boxes 11 is equipped with a geared motor 23 whose output end is connected to one of the shaft columns 21. The roll release film suspended between the two upright boxes 11 is rotated counterclockwise under the control of the geared motor 23 so that the rolled release film is loosened. Another vertical box 11 is equipped with a first electro-hydraulic rod 28. One end of the first electro-hydraulic rod 28 passes through the vertical box 11 and is connected to a mounting plate. Two bearing seats are fixed to one of the vertical boxes 11 and the mounting plate respectively. In particular, in order to ensure the stability of the mounting plate, two guide rods are fixed on one side of the mounting plate, and both guide rods are inserted into the vertical box 11 that is close to it. When the mounting plate moves, the guide rods can move with it, but always keep one end inside the vertical box 11. With this cooperation, they can play an auxiliary support role for the mounting plate. Specifically, when installing the roll release film to be cleaned, one end of the roll is first inserted into the stepped column 22 in the bearing seat fixed to the vertical box 11. At this time, the other end of the roll is away from the other stepped column 22. Then, by starting the first electric hydraulic rod 28, the mounting plate is driven to move the stepped column 22 on it to gradually approach the roll until it is inserted into the roll. At this time, the roll is suspended between the two vertical boxes 11. like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, a friction block 27 is inserted into the outer wall of the stepped column 22 through a slot. In the initial state, the top of the friction block 27 is flush with the surface of the stepped column 22, which facilitates the insertion of the drum. On both sides of the friction block 27, a first spring is installed through a support block, the end of which is connected to the inner wall of the stepped column 22. In particular, the two ends of the first spring are connected to the support block and the inner wall of the stepped column 22, respectively. A screw 24 is rotatably connected inside the stepped column 22. The outer surface of the screw 24 is threaded with multiple three-sloping seats 25 that are adapted to the friction block 27. In particular, the friction block 27 extends into the stepped column 22. One end is inclined and fits against the three-inclined seat 25. At the same time, a slider is fixed at the bottom of the three-inclined seat 25. A groove adapted to the slider is opened on the inner bottom wall of the stepped column 22, so that the slider can slide on the inner bottom wall of the stepped column 22, thereby making the three-inclined seat 25 only able to move in a straight line. A first motor 26 with an output end connected to the screw 24 is installed at one end of the stepped column 22. Preferably, a battery is provided in the inner cavity of the stepped column 22 for independent power supply of the first motor 26. The battery is rechargeable and needs to be charged when the device is stopped after a period of use. Specifically, the stepped shape of the stepped column 22 allows it to be used to connect rolls of release film of different sizes. Each step position is provided with a friction block 27, and the friction blocks 27 are arranged in groups of three. When the two ends of the roll are connected to the two stepped columns 22 respectively, the first motor 26 is started to drive the screw 24 to rotate clockwise, causing the three inclined surface seat 25 to move forward. During the process, under the action of its inclined surface, the friction blocks 27 are gradually driven to move outward, thereby abutting against the inner wall of the roll and fixing the roll to the surface of the stepped column 22. In this state, when the stepped column 22 rotates, it will drive the roll to rotate together. At this time, the geared motor 23 drives the shaft 21 to rotate the stepped column 22 counterclockwise (opposite to the winding direction of the release film), causing the wound and taut release film to gradually loosen, so that it is stuck together at the top and spread out at the bottom, as shown. Figure 1 As shown, the rolled release film can now be cleaned.

[0020] like Figure 1 , Figure 2 , Figure 9 and Figure 12As shown, a steam generating unit 30 is installed at the bottom of the mounting bracket 10. The steam generating unit 30 includes a steam generator 31. In particular, the steam generator 31 generates steam in a known manner, which will not be described in detail here. The steam generated by the steam generator 31 comes into contact with the loose release membrane surface through a steam guide 32 installed inside the vertical box 11, so as to clean the membrane surface. The steam guide component 32 includes a steam inlet hood 321 fixed inside the vertical box 11. A guide hood 322 is fixedly connected to one side of the steam inlet hood 321. A steam outlet hole is opened on the inner wall of the guide hood 322. A three-way solenoid valve 323 is installed at the output end of the steam generator 31 through a connecting pipe. Two ends of the three-way solenoid valve 323 are respectively connected to the steam inlet hood 321 through a delivery pipe 324. Specifically, when the release film is loose, the steam generator 31 is started. The steam generated is sent to one of the steam inlet hoods 321 through the delivery pipe 324, and then blown into the gap of the release film through the steam outlet to clean the surface of the release film. It should be noted that the state of the connecting pipe and the delivery pipes 324 at different positions should be controlled by the three-way solenoid valve 323 to ensure that the connecting pipe is connected to one of the delivery pipes 324, so that the steam enters from one end of the release film and exits from the other end.

[0021] like Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, the mounting frame 10 is also equipped with a positioning unit 40. The positioning unit 40 includes a base fixed to the inside of the upright box 11. A fixed support seat 41 is installed at one end of the upper surface of the base. A movable support seat 42 is slidably connected to the upper surface of the base via a slide rail. A second electric hydraulic rod 44 is installed on the lower surface of the base, with one end connected to the movable support seat 42. Both the fixed support 41 and the movable support 42 are rotatably connected to a connecting ring 43. In particular, both the fixed support 41 and the movable support 42 have annular grooves on their inner walls. The connecting ring 43 is rotatably connected to the annular groove. At the same time, a damping pad is provided on the inner wall of the annular groove, so that the connecting ring 43 can only rotate by external force and its position can be limited after rotation, and it will not rotate on its own. Multiple bidirectional telescopic rods 45 are installed on the inner sides of the two connecting rings 43. Specifically, the bidirectional telescopic rod 45 includes a middle rod, with slots at both ends of the middle rod. A first extension section is inserted into the slot, a second extension section is inserted into the first extension section, and a third extension section is inserted into the second extension section. The two third extension sections are fixed to the two connecting rings 43 respectively. In order to ensure that the extension sections do not detach during the telescopic process, limiting grooves are provided on the inner top and bottom walls of the slots. The upper and lower surfaces of the first, second, and third extension sections are fixed with limiting sliders that are adapted to the limiting grooves. With the cooperation of the limiting grooves and limiting sliders, the movement range of the extension sections and the middle rod can be limited, preventing detachment. A third electro-hydraulic rod 46 is fixed in the middle of the bidirectional telescopic rod 45. The third electro-hydraulic rod 46 passes through one end of the bidirectional telescopic rod 45 and is rotatably connected to a connector via a U-shaped seat. A pressure rod 47 is fixed at the bottom of the connector. Multiple positioning holes are opened on both sides of the connector. A hemispherical column is connected to the positioning hole via a second spring. Multiple limiting holes are opened on both sides of the U-shaped seat in a circular array. The hemispherical column is engaged in the corresponding limiting hole, so that the position of the pressure rod 47 is fixed. In particular, a through hole corresponding to the pressure rod 47 is opened on the vertical box 11 located on one side of the fixed support 41. The center of the steam inlet hood 321 and the guide hood 322 near the fixed support 41 is fixed with a rod tube corresponding to the lowermost pressure rod 47. The rod tube corresponds to the through hole at the bottom. The through hole and the rod tube are used for the pressure rod 47 to pass through. Specifically, in the initial state, the moving support 42 is close to the fixed support 41, the bidirectional telescopic rod 45 is in a retracted state, and one end of the pressure rod 47 is inserted into the vertical box 11 on the side near the fixed support 41. In this state, it is convenient to put one end of the roll of release film into the stepped column 22 on the side near the fixed support 41. It should be noted that when putting in the roll, the roll should be tilted first so that one end is tilted upward, and then it is sent between the two support seats. Then, one end is fitted onto the stepped column 22 on the side near the fixed support 41. Then, the first electro-hydraulic rod 28 drives the other stepped column 22 to be inserted into the roll. At this time, the roll is suspended. Then, the second electro-hydraulic rod 44 drives the moving support 42 to gradually move away from the fixed support 41. During the process, the bidirectional telescopic rod 45 gradually unfolds. At this time, the friction block 27 is driven to push against the roll, and then the release film is relaxed. After relaxation, steam cleaning operation is performed.

[0022] like Figure 8 and Figure 12As shown, a second motor 48 is mounted on one side of the fixed support base 41 via a bracket. An L-shaped adjusting rod 49 is mounted on the output end of the second motor 48. In particular, the outer wall of the L-shaped adjusting rod 49 has a through groove to ensure that the pressure rod 47 can move smoothly toward the through tube. In the initial state, the top of the L-shaped adjusting rod 49 faces the vertical box 11, and this state does not affect the up and down movement of the pressure rod 47.

[0023] Both connecting rings 43 have a fourth electro-hydraulic rod 410 mounted on their outer walls via a base. A limiting post 411 is mounted at one end of each fourth electro-hydraulic rod 410. Multiple limiting holes 412, arranged in a ring array and adapted to the limiting posts 411, are opened on the outer wall of the shaft post 21. Specifically, after steam cleaning of the release film loosened to the bottom of the roll, the second motor 48 drives the L-shaped adjusting rod 49 to rotate 180°, so that its top point faces the pressure rod 47. In this state, the top of the L-shaped adjusting rod 49 is above the pressure rod 47 located below. Then, the third electro-hydraulic rod 46 below drives the pressure rod 47 to move upwards. During the movement, one end of the pressure rod 47 gradually abuts against the L-shaped adjusting rod 49, and continues to move upwards... During the movement, the L-shaped adjusting rod 49 causes the pressure rod 47 to gradually tilt. After tilting to the required angle, the hemispherical column is engaged in the corresponding limiting hole under the action of the second spring, fixing the position of the tilted pressure rod 47. At this time, the L-shaped adjusting rod 49 is driven to rotate to the initial state (i.e., rotated 180° again) by the second motor 48. Then, the tilted pressure rod 47 is driven to move upward by the third electric hydraulic rod 46. During the continued movement, the upward tilted end of the pressure rod 47 first contacts the end of the release film that has loosened to the bottom of the roll, causing the end of the release film to tilt upward. At this time, the water droplets generated after cleaning will flow towards the end close to the fixed support 41 under the action of the tilting force and gradually flow away from the surface of the release film. After completing the above operations, the second motor 48 drives the L-shaped adjusting rod 49 to rotate to the top facing the pressure rod 47. Then, the third electric hydraulic rod 46 drives the inclined pressure rod 47 to move downward. During the downward movement, the downward inclined end of the pressure rod 47 gradually contacts the L-shaped adjusting rod 49. Under the action of the L-shaped adjusting rod 49, the pressure rod 47 is gradually driven to rotate back to the horizontal state. After returning to the horizontal state, the L-shaped adjusting rod 49 is adjusted back to the initial state. At this time, all the third electric hydraulic rods 46 are activated to drive the four horizontal pressure rods 47 to gradually abut against the release film, so that the loose release film is fixed on the roll and can rotate with the roll without being wound up or unwound when the roll rotates. After completing the above operations, the fourth electric hydraulic rod 410 is activated to drive the limiting post 411 to insert into the corresponding limiting hole 412. At this time, the reduction motor 23 is activated to drive the shaft post 21 to rotate together with the stepped post 22 and the drum. In this state, since the limiting post 411 is inserted into the limiting hole 412 on the shaft post 21, the connecting ring 43 will drive the pressure rod 47 to rotate together, thereby changing the position of the release film. After rotating 180°, the release film that was originally loose at the bottom will be moved to the top position, while the release film that was originally stuck at the top under the action of gravity will be moved to the bottom position. At this point, the third electric hydraulic rod 46 at the bottom is activated to drive the pressure rod 47 at the bottom to move downwards and away from the release film. At this time, the release film, which was originally in a bonded state, gradually unfolds into a loose state. Conversely, the release film, which was originally in a loose state at the top, will remain bonded under the action of the pressure rod 47 and gravity. Then, by activating the other third electric hydraulic rods 46, the pressure rods 47 at other positions are driven away from the release film. In this state, the release film at the top will remain bonded under the action of gravity. Next, the steam generator 31 is started to clean the loose release film with steam, so that the rolled release film can be effectively cleaned. After cleaning is completed and water droplets are drained, the shaft column 21 is controlled to rotate clockwise by the reduction motor 23, so that the loose release film can be rewound. Then the friction block 27 is released from the restriction on the roll, and the moving support 42 is reset. The stepped column 22 on the first electric hydraulic rod 28 is moved away from the roll, and the roll can be removed at this time, completing the cleaning of the rolled release film. In particular, cleaning the roll release film in the above manner will prevent the film from sagging when it is laid vertically and then unrolled, thus avoiding wrinkles at the bottom caused by the film sagging.

[0024] Specifically, the steam cleaning device for the surface of release film used in release film processing operates as follows: 1. Installation and fixing of the reel: In the initial state, the moving support 42 is close to the fixed support 41, the bidirectional telescopic rod 45 is retracted, and one end of the pressure rod 47 is inserted into the vertical box 11. One end of the roll of release film is tilted and placed between the support seats, and then horizontally mounted on one side of the stepped column 22. Then the first electric hydraulic rod 28 is activated to drive the mounting plate and guide rod to move, so that the other side of the stepped column 22 is inserted into the other end of the roll, realizing the horizontal suspension of the film roll. Start the first motor 26, drive the screw 24 to rotate clockwise, drive the three inclined surface seat 25 to move along the slide groove, and drive the friction block 27 to extend outward through the inclined surface action of the three inclined surface seat 25, abut against the inner wall of the drum, and firmly fix the drum on the two stepped columns 22. 2. Positioning unit 40 adjustment: Start the second electric hydraulic rod 44 to drive the moving support 42 away from the fixed support 41, and the bidirectional telescopic rod 45 unfolds to a state that matches the length of the film roll. 3. Loosening of the film: Start the reduction motor 23 to drive the shaft column 21, the stepped column 22 and the roll to rotate counterclockwise (opposite to the winding direction), so that the rolled release film gradually loosens and is in a state of "adhesion at the top and dispersion at the bottom"; 4. Steam cleaning: Start the steam generator 31, and control the steam to enter the steam inlet hood 321 through one of the delivery pipes 324 via the three-way solenoid valve 323. Then, the steam is blown into the gap of the loose membrane layer through the steam outlet of the guide hood 322. The steam is discharged from the other end of the membrane roll, completing the cleaning of the loose membrane layer below. 5. Condensate drainage: After cleaning, start the second motor 48 to drive the L-shaped adjusting rod 49 to rotate 180° so that its top is facing the pressure rod 47; start the third electric hydraulic rod 46 below to drive the pressure rod 47 to move upward and tilt under the action of the L-shaped adjusting rod 49. The tilt angle of the pressure rod 47 is fixed by the engagement of the hemispherical column and the limiting hole; then reset the L-shaped adjusting rod 49, and the tilted end of the pressure rod 47 abuts against the membrane layer, causing the membrane to tilt and guide the condensate to drain to one end; 6. Membrane roll flipping and secondary cleaning: Start the fourth electric hydraulic rod 410 to drive the limiting post 411 to insert into the limiting hole 412 of the shaft post 21, so that the connecting ring 43 and the shaft post 21 rotate synchronously; start the reduction motor 23 to drive the film roll to rotate 180°, so that the originally attached upper film is transferred to the bottom and naturally loosened, and the originally cleaned loose film layer is transferred to the top and remains attached.

[0025] Start the third electric hydraulic rod 46 below to drive the corresponding pressure rod 47 to move downward away from the membrane layer, then start the steam generator 31 and switch the steam delivery path through the three-way solenoid valve 323 to perform secondary cleaning on the newly loose membrane layer. After cleaning, repeat the condensate discharge step. 7. Film rewinding: After the second cleaning is completed, start the reduction motor 23 and drive the shaft column 21 to rotate clockwise (in the same direction as the winding) to rewind the loose release film tightly onto the roll. 8. Roll Removal: After rewinding, start the first motor 26 to drive the screw 24 to rotate counterclockwise, so that the friction block 27 is reset; start the fourth electric hydraulic rod 410 to make the limiting post 411 disengage from the limiting hole 412; start the first electric hydraulic rod 28 to move the stepped post 22 on one side away from the roll; finally, remove the cleaned roll release film from the stepped post 22 to complete the entire cleaning process.
