Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic shielding films, in particular to surface dust removal equipment and a dust removal method for electromagnetic shielding films. Background Art

[0002] Electromagnetic shielding glass is a light-transmitting shielding device that protects against electromagnetic radiation and interference. It is widely used in fields such as optics, electronics, metal materials, chemicals, glass, and machinery, and is widely used in electromagnetic compatibility. It is primarily used in 3C products such as laptops, GPS, ADSL, and mobile phones, as these products can generate noise due to high-frequency electromagnetic interference, affecting communication quality. During the production process, dust or debris may accumulate on the surface of the shielding film, necessitating dust removal during processing.

[0003] The surface dust removal of electromagnetic shielding film usually relies on the adhesive roller for cleaning operation. In this method, the adhesive roller is driven by the friction between the adhesive roller and the shielding film in transmission. Since this type of equipment only relies on the adhesion of the adhesive roller to clean the dust on the surface of the film, the cleaning effect is limited and it is impossible to effectively remove stubborn or fine particles. Therefore, this method is often difficult to achieve the ideal cleaning standard in actual application. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a surface dust removal device for an electromagnetic shielding film, comprising a dust removal assembly, the dust removal assembly comprising a housing, a motor 1 being fixedly connected to the front of the housing, and a winding roller being fixedly connected to the output end of the motor 1;

[0005] The cleaning assembly includes a fixed plate arranged inside the shell, the inner wall of the fixed plate is slidably connected to a lifting frame, and the outer wall of the lifting frame is rotatably connected to a lifting sleeve;

[0006] The discharge component includes a shielding plate slidably connected to the inner wall of the fixed plate, a second spring is fixedly connected to the outer wall of the shielding plate, and an air guide cavity is opened inside the fixed plate.

[0007] Preferably, the outer surface of the winding roller is rotatably connected to the inner wall of the shell, the outer surface of the winding roller contacts a belt, the inner wall of the shell is fixedly connected to a fixed shaft, the outer surface of the fixed shaft is rotatably connected to a rotating sleeve, the winding roller is transmission-connected to the rotating sleeve through a belt, the outer surface of the rotating sleeve is fixedly connected to a driven roller, and the inner wall of the shell is rotatably connected to a discharge roller.

[0008] Preferably, the outer surface of the discharge roller contacts with the shielding film, the outer surface of the driven roller contacts with the outer surface of the shielding film, the inner wall of the driven roller is slidably connected to the motor 2, the output end of the motor 2 is fixedly connected to the adhesion roller, the outer surface of the adhesion roller contacts with the belt 2, the inner wall of the belt 2 also contacts with several adhesion rollers, the adhesion roller corresponding to the motor 2 and the several adhesion rollers not corresponding to the motor 2 are all connected by the belt 2 transmission. When using this device, first install this device to the specified position, then pass the shielding film through the two driven rollers and the discharge roller in turn, and finally pass the left side of the shielding film through the left side of the inner wall of the shell and pull the shielding film to the right. The pulling force needs to keep the shielding film taut at all times. At the same time, start motor 1 and motor 2. Motor 1 will drive the winding roller to rotate. At this time, a large amount of shielding film has been wound on the surface of the winding roller. During the rotation of the winding roller, the shielding film will be transported to the left. During the rotation of the winding roller, the two rotating sleeves will be driven to rotate through belt 1, and then the two driven rollers will be driven to rotate. Motor 2 will drive the adhesion roller to rotate, and the direction of rotation of the adhesion roller is opposite to that of the driven roller. During the rotation of the adhesion roller, the other several adhesion rollers will be driven to rotate through belt 2.

[0009] Preferably, the plurality of adhesive rollers are slidably connected to the inner wall of the driven roller, the outer wall of the second belt contacts a plurality of rotating shafts, the outer surfaces of the plurality of rotating shafts are rotatably connected to sliding seats, the inner wall of the sliding seat is slidably connected to a limit rod, the outer surface of the limit rod is fixedly connected to the inner wall of the driven roller, and the outer surfaces of the plurality of sliding seats are all in contact with annular springs. It should be noted that the annular spring will apply a contraction force to the plurality of rotating shafts through the sliding seat to move them closer to each other. This contraction force can keep the second belt in a taut state at all times, so that the second belt can still drive the adhesive roller to rotate while it slides. When the driven roller drives the rotating adhesive roller to rotate until the outer surface of the adhesive roller contacts the surface of the shielding film, the adhesive roller removes dust from the surface of the shielding film through the adhesive force of its surface. At the same time, since the rotation direction of the adhesive roller is opposite to the conveying direction of the shielding film, the adhesive roller will additionally apply a force to the shielding film to resist its movement. This design can increase the contact pressure between the adhesive roller and the shielding film through this resisting force, so that the sticky surface of the adhesive roller can more effectively capture and remove dust and particles on the film surface, further improving the cleaning effect.

[0010] Preferably, a plurality of fixing plates are provided. The plurality of fixing plates correspond to the plurality of adhesion rollers one by one. The outer surfaces of the plurality of fixing plates are fixedly connected to the inner wall of the driven roller. The outer surface of the lifting sleeve contacts the outer surface of the adhesion roller. A bottom plate is fixedly connected to the side of the lifting frame away from the adhesion roller. A first spring is fixedly connected to the side of the bottom plate close to the fixing plate. The first spring is fixedly connected to the side of the fixing plate close to the bottom plate away from the bottom plate. A scraper is fixedly connected to the side of the fixing plate close to the adhesion roller. After the adhesion roller rotates to contact the surface of the shielding film, the shielding film will apply a pressure to the adhesion roller, so that the adhesion roller in contact with the shielding film will be pressed into the inside of the driven roller by a certain distance. During the movement of the adhesion roller, it will drive the lifting frame to move together through the lifting sleeve. The lifting frame will drive the bottom plate to move together and stretch the first spring. It should be noted that in the initial state, the first spring applies an elastic force to the adhesion roller, which can keep it in a state of protruding from the outside of the driven roller. When the outer surface of the adhesion roller moves to contact the surface of the scraper, as the adhesion roller continues to rotate, the dust adhered to its outer surface will be scraped off by the scraper. The scraped dust will fall into the inside of the fixing plate along the surface of the scraper. This design can scrape off the dust adhered to the surface of the adhesion roller through the scraper, thereby ensuring that the adhesion roller maintains good adhesion, improving the cleaning efficiency of the dust on the surface of the shielding film, and reducing the risk of cross-contamination between the adhesion roller and the shielding film.

[0011] Preferably, the shielding plate is fixedly connected to the side of the second spring close to the scraper on the side away from the scraper. The second spring is fixedly connected to the inner wall of the fixing plate on the side away from the shielding plate. A fixing box is fixedly connected to the side of the fixing plate away from the adhesion roller. A pressing plate is slidably connected to the inner wall of the fixing box. The pressing plate is fixedly connected to the outer wall of the bottom plate on the side away from the fixing plate. Two air guide blocks are respectively fixedly connected to the outer wall of the fixing box. During the downward movement of the bottom plate, it will also drive the pressing plate to move downward together. During the movement of the pressing plate, it will suck the air inside the fixing plate into the fixing box through the air guide cavity, so that a negative pressure is generated inside the fixing plate to suck the shielding plate and compress the second spring. At this time, the surface of the shielding plate will be separated from the surface of the scraper, so that the scraper can normally scrape off the dust on the surface of the adhesion roller. When the adhesion roller is separated from the shielding film, at this time, the entire lifting frame will reset under the action of the first spring, and the shielding plate will also reset and contact the scraper again. At this time, the scraper will block the dust falling into the inside of the fixing plate to prevent the dust from falling out of the fixing plate again during the subsequent continuous rotation of the driven roller. This design blocks the dust falling into the inside of the fixing plate through the shielding plate, which can prevent the dust from being released again in subsequent operations and keep the equipment clean.

[0012] Preferably, an air guide pipe is fixedly connected to the side of the air guide block away from the fixed box. The air guide pipe is fixedly connected to a jet block at the end away from the air guide block. The outer surface of the jet block is fixedly connected to the inner wall of the fixing plate. The fixing plate is fixedly connected to an air guide dust shell on the side close to the rotating sleeve. The outer wall of the air guide dust shell is fixedly connected to the outer surface of the rotating sleeve. A spiral blade is rotatably connected to the inner wall of the rotating sleeve. The inner wall of the spiral blade is fixedly connected to the outer surface of the fixed shaft. During the downward movement of the pressing plate, the air inside the fixed box will be squeezed and pushed into the air guide block. The air guide block will introduce the air into the air guide pipe. The air guide pipe will introduce the air into the inside of the jet block. The jet block will spray the air into the space formed by the fixing plate, the scraping plate and the shielding plate, so as to push the dust falling into the fixing plate towards the direction close to the air guide dust shell. The dust blown to the air guide dust shell will fall into the inside of the rotating sleeve through the air guide dust shell. As the rotating sleeve rotates, a relative rotation will be generated between it and the spiral blade. Therefore, the dust falling into the rotating sleeve can be conveyed to the back by the spiral blade and finally fall out from the back of the rotating sleeve. This design can effectively guide the dust into the inside of the rotating sleeve and finally discharge it from the inside of the rotating sleeve, reducing the frequency of manual cleaning and lowering the maintenance cost.

[0013] A dust removal method for a surface dust removal device of an electromagnetic shielding film includes the following steps:

[0014] S1: When using this device, first install this device at the designated position, and then install the shielding film on this device. Start the first motor and the second motor. The first motor will drive two driven rollers to rotate through the winding roller, and the second motor will drive the adhesion roller to rotate;

[0015] S2: After the adhesion roller rotates to contact the surface of the shielding film, it will be pressed into the inside of the driven roller by a certain distance. When the adhesion roller moves to contact the surface of the scraping plate, the dust adhered to its outer surface will be scraped off by the scraping plate;

[0016] S3: During the downward movement of the pressing plate, the air inside the fixed box will be introduced into the inside of the jet block. The dust will be blown and fall into the inside of the rotating sleeve from the air guide dust shell. The spiral blade can convey the falling dust to the back and finally fall out from the back of the rotating sleeve.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, there are a starting motor one and a motor two. The motor one drives the winding roller to rotate. At this time, a large amount of shielding film has been wound on the surface of the winding roller. During the rotation of the winding roller, the shielding film is conveyed to the left. During the rotation of the winding roller, it also drives two rotating sleeves to rotate through a belt one, and then drives two driven rollers to rotate. The motor two drives the adhesion roller to rotate, and the rotation direction of the adhesion roller is opposite to that of the driven roller. During the rotation of the adhesion roller, it drives several other adhesion rollers to rotate through a belt two. It should be noted that the annular spring gives a contracting force to several rotating shafts through the sliding seat, so that the belt two can always be in a tense state through this contracting force, so that the belt two can still drive the adhesion roller to rotate when the adhesion roller slides. When the driven roller drives the rotating adhesion roller to rotate until the outer surface of the adhesion roller contacts the surface of the shielding film, the adhesion roller will remove the dust on the surface of the shielding film through the adhesion force on its surface. At the same time, because the rotation direction of the adhesion roller is opposite to the conveying direction of the shielding film, the adhesion roller will additionally apply a force against its movement to the shielding film. This design can increase the contact pressure between the adhesion roller and the shielding film through this counter force, so that the adhesive surface of the adhesion roller can more effectively capture and remove the dust and particles on the film surface, and further improve the cleaning effect.

[0019] 2. After the adhesion roller rotates to contact the surface of the shielding film in the present invention, the shielding film gives a pressure to the adhesion roller, so that the adhesion roller in contact with the shielding film is pressed into the inside of the driven roller by a certain distance. During the movement of the adhesion roller, it drives the jacking frame to move together through the jacking sleeve, and the jacking frame drives the bottom plate to move together and stretch the spring one. It should be noted that in the initial state, the spring one gives an elastic force to the adhesion roller to keep it in a state of protruding outside the driven roller. When the outer surface of the adhesion roller moves to contact the surface of the scraper, as the adhesion roller continues to rotate, the dust adhered to its outer surface will be scraped off by the scraper, and the scraped dust will fall into the inside of the fixing plate along the surface of the scraper. This design can scrape off the dust attached to the surface of the adhesion roller through the scraper, so as to ensure that the adhesion roller maintains good adhesion, thereby improving the cleaning efficiency of the dust on the surface of the shielding film and reducing the risk of cross-contamination between the adhesion roller and the shielding film.

[0020] 3. During the downward movement of the bottom plate of the present invention, it will also drive the pressing plate to move downward together. During the movement of the pressing plate, it will suck the air inside the fixing plate into the fixing box through the air guide cavity, thereby generating negative pressure inside the fixing plate to suck the shielding plate and compress the second spring. At this time, the surface of the shielding plate will be separated from the surface of the scraping plate, enabling the scraping plate to normally scrape the dust on the surface of the adhesion roller. When the adhesion roller is separated from the shielding film, the entire lifting frame will reset under the action of the first spring at this time, and the shielding plate will also reset and come into contact with the scraping plate again. At this time, the scraping plate will block the dust falling into the fixing plate to prevent the dust from falling out of the fixing plate again during the subsequent continuous rotation of the driven roller. This design blocks the dust falling into the fixing plate through the shielding plate, which can prevent the dust from being released again during subsequent operations and keep the equipment clean.

[0021] 4. During the downward movement of the pressing plate of the present invention, it will also squeeze the air inside the fixing box and push it into the air guide block. The air guide block will introduce the air into the air guide pipe, and the air guide pipe will introduce the air into the inside of the air jet block. The air jet block will spray the air into the space composed of the fixing plate, the scraping plate, and the shielding plate, thereby pushing the dust falling into the fixing plate in the direction close to the dust guide shell. The dust blown to the dust guide shell will fall into the inside of the rotating sleeve through the dust guide shell. As the rotating sleeve rotates, relative rotation will occur between it and the spiral blade, and then the dust falling into the rotating sleeve can be conveyed to the back by the spiral blade and finally fall out from the back of the rotating sleeve. This design can effectively guide the dust into the inside of the rotating sleeve and finally discharge it from the inside of the rotating sleeve, reducing the frequency of manual cleaning and lowering the maintenance cost.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1, please refer to Figure 1 - Figure 3 , the present invention is a surface dust removal device for an electromagnetic shielding film, including a dust removal component 1. The dust removal component 1 includes an outer shell 101, a motor 1 102 is fixedly connected to the front surface of the outer shell 101, and a winding roller 103 is fixedly connected to the output end of the motor 1 102;

[0037] Cleaning component 2, the cleaning component 2 includes a fixing plate 201 arranged inside the housing 101, a lifting frame 203 is slidably connected to the inner wall of the fixing plate 201, and a lifting sleeve 202 is rotatably connected to the outer wall of the lifting frame 203;

[0038] Discharging component 3, the discharging component 3 includes a shielding plate 301 slidably connected to the inner wall of the fixing plate 201, a second spring 302 is fixedly connected to the outer wall of the shielding plate 301, and an air guiding cavity 303 is formed inside the fixing plate 201.

[0039] The outer surface of the winding roller 103 is rotatably connected to the inner wall of the housing 101. The outer surface of the winding roller 103 is in contact with a first belt 104. A fixed shaft 107 is fixedly connected to the inner wall of the housing 101. A rotating sleeve 105 is rotatably connected to the outer surface of the fixed shaft 107. The winding roller 103 is drivingly connected to the rotating sleeve 105 through the first belt 104. A driven roller 106 is fixedly connected to the outer surface of the rotating sleeve 105. An output roller 108 is rotatably connected to the inner wall of the housing 101.

[0040] The outer surface of the output roller 108 is in contact with a shielding film 1081. The outer surface of the driven roller 106 is in contact with the outer surface of the shielding film 1081. A second motor 109 is slidably connected to the inner wall of the driven roller 106. The output end of the second motor 109 is fixedly connected to an adhesion roller 110. The outer surface of the adhesion roller 110 is in contact with a second belt 111. The inner wall of the second belt 111 is also in contact with a plurality of adhesion rollers 110. The adhesion roller 110 corresponding to the second motor 109 and the plurality of adhesion rollers 110 not corresponding to the second motor 109 are all drivingly connected through the second belt 111. When using this device, first install this device at a designated position, then pass the shielding film 1081 through the two driven rollers 106 and the output roller 108 in sequence, and finally pass the left side of the shielding film 1081 through the left side inner wall of the housing 101 and pull the shielding film 1081 to the left. This pulling force needs to keep the shielding film 1081 always taut. At the same time, start the first motor 102 and the second motor 109. The first motor 102 will drive the winding roller 103 to rotate. A large amount of the shielding film 1081 has been wound on the surface of the winding roller 103 at this time. During the rotation of the winding roller 103, the shielding film 1081 will be conveyed to the left. During the rotation of the winding roller 103, it will also drive the two rotating sleeves 105 to rotate through the first belt 104, thereby driving the two driven rollers 106 to rotate. The second motor 109 will drive the adhesion roller 110 to rotate, and the rotation direction of the adhesion roller 110 is opposite to that of the driven roller 106. During the rotation of the adhesion roller 110, it will drive a plurality of other adhesion rollers 110 to rotate through the second belt 111.

[0041] A plurality of adhesion rollers 110 are all slidably connected to the inner wall of the driven roller 106. A plurality of rotating shafts 112 are in contact with the outer wall of the second belt 111. Sliding seats 113 are respectively rotatably connected to the outer surfaces of the plurality of rotating shafts 112. A limiting rod 114 is slidably connected to the inner wall of the sliding seat 113. The outer surface of the limiting rod 114 is fixedly connected to the inner wall of the driven roller 106. Annular springs 115 are in contact with the outer surfaces of the plurality of sliding seats 113. It should be noted that the annular springs 115 will give a contraction force that makes the plurality of rotating shafts 112 approach each other through the sliding seats 113. Through this contraction force, the second belt 111 can always be in a taut state, so that the second belt 111 can still drive the adhesion roller 110 to rotate when the adhesion roller 110 slides. When the driven roller 106 drives the rotating adhesion roller 110 to rotate until the outer surface of the adhesion roller 110 contacts the surface of the shielding film 1081, the adhesion roller 110 will remove the dust on the surface of the shielding film 1081 through the adhesion force on its surface. At the same time, since the rotation direction of the adhesion roller 110 is opposite to the conveying direction of the shielding film 1081, the adhesion roller 110 will additionally apply a force against its movement to the shielding film 1081. This design can increase the contact pressure between the adhesion roller 110 and the shielding film 1081 through this counter force, making the adhesive surface of the adhesion roller more effectively capture and remove dust and particles on the film surface, and further improving the cleaning effect.

[0042] Embodiment 2, please refer to Figure 4 - Figure 10, the present invention is a surface dust removal device for an electromagnetic shielding film. On the basis of Example 1, a plurality of fixing plates 201 are provided. The plurality of fixing plates 201 correspond to the plurality of adhesion rollers 110 one by one. The outer surfaces of the plurality of fixing plates 201 are fixedly connected to the inner wall of the driven roller 106. The outer surface of the lifting sleeve 202 contacts the outer surface of the adhesion roller 110. On the side away from the adhesion roller 110, the lifting frame 203 is fixedly connected to a bottom plate 204. On the side close to the fixing plate 201, the bottom plate 204 is fixedly connected to a first spring 205. The first spring 205 is fixedly connected to the side of the fixing plate 201 close to the bottom plate 204 on the side away from the bottom plate 204. On the side close to the adhesion roller 110, the fixing plate 201 is fixedly connected to a scraper 206. After the adhesion roller 110 rotates to contact the surface of the shielding film 1081, the shielding film 1081 will give a pressure to the adhesion roller 110, so that the adhesion roller 110 in contact with the shielding film 1081 will be pressed into the inside of the driven roller 106 by a certain distance. During the movement of the adhesion roller 110, it will drive the lifting frame 203 to move together through the lifting sleeve 202. The lifting frame 203 will drive the bottom plate 204 to move together and stretch the first spring 205. It should be noted that in the initial state, the first spring 205 gives an elastic force to the adhesion roller 110 to keep it in a state of protruding outside the driven roller 106. When the outer surface of the adhesion roller 110 moves to contact the surface of the scraper 206, as the adhesion roller 110 continues to rotate, the dust adhered to its outer surface will be scraped off by the scraper 206. The scraped dust will fall into the inside of the fixing plate 201 along the surface of the scraper 206. This design can scrape off the dust attached to the surface of the adhesion roller 110 through the scraper 206, thereby ensuring that the adhesion roller maintains good adhesion, improving the cleaning efficiency of the dust on the surface of the shielding film 1081, and reducing the risk of cross-contamination between the adhesion roller 110 and the shielding film 1081.

[0043] The baffle 301 is fixedly connected to the side of the second spring 302 close to the squeegee 206 on the side away from the squeegee 206. The second spring 302 is fixedly connected to the inner wall of the fixing plate 201 on the side away from the baffle 301. A fixing box 305 is fixedly connected to the fixing plate 201 on the side away from the adhesion roller 110. A pressing plate 304 is slidably connected to the inner wall of the fixing box 305. The pressing plate 304 is fixedly connected to the outer wall of the bottom plate 204 on the side away from the fixing plate 201. Two air guiding blocks 306 are respectively fixedly connected to the outer wall of the fixing box 305. During the downward movement of the bottom plate 204, it will also drive the pressing plate 304 to move downward together. During the movement of the pressing plate 304, it will suck the air inside the fixing plate 201 into the fixing box 305 through the air guiding cavity 303, thereby creating a negative pressure inside the fixing plate 201 to suck and compress the second spring 302 by the baffle 301. At this time, the surface of the baffle 301 will be separated from the surface of the squeegee 206, enabling the squeegee 206 to normally scrape the dust on the surface of the adhesion roller 110. When the adhesion roller 110 is separated from the shielding film 1081, the entire lifting frame 203 will reset under the action of the first spring 205 at this time, and the baffle 301 will also reset and come into contact with the squeegee 206 again. At this time, the squeegee 206 will block the dust falling into the fixing plate 201 to prevent the dust from falling out of the fixing plate 201 again during the subsequent continuous rotation of the driven roller 106. This design blocks the dust falling into the fixing plate 201 through the baffle 301, which can prevent the dust from being released again during subsequent operations and keep the equipment clean.

[0044] The air guide block 306 is fixedly connected to an air guide pipe 307 on the side away from the fixed box 305. The air guide pipe 307 is fixedly connected to an air jet block 308 at the end away from the air guide block 306. The outer surface of the air jet block 308 is fixedly connected to the inner wall of the fixed plate 201. The fixed plate 201 is fixedly connected to a dust guide shell 309 on the side close to the rotating sleeve 105. The outer wall of the dust guide shell 309 is fixedly connected to the outer surface of the rotating sleeve 105. A spiral blade 310 is rotatably connected to the inner wall of the rotating sleeve 105. The inner wall of the spiral blade 310 is fixedly connected to the outer surface of the fixed shaft 107. During the downward movement of the pressing plate 304, the air inside the fixed box 305 will be squeezed and pushed into the air guide block 306. The air guide block 306 will introduce the air into the air guide pipe 307. The air guide pipe 307 will introduce the air into the interior of the air jet block 308. The air jet block 308 will spray the air into the space formed by the fixed plate 201, the scraping plate 206, and the shielding plate 301. Thus, the dust falling into the interior of the fixed plate 201 can be pushed towards the direction close to the dust guide shell 309. The dust blown to the dust guide shell 309 will fall into the interior of the rotating sleeve 105 through the dust guide shell 309. As the rotating sleeve 105 rotates, relative rotation will occur between it and the spiral blade 310. Thus, the dust falling into the rotating sleeve 105 can be conveyed to the back by the spiral blade 310 and finally fall out from the back of the rotating sleeve 105. This design can effectively guide the dust into the interior of the rotating sleeve 105 and finally discharge it from the interior of the rotating sleeve 105, reducing the frequency of manual cleaning and lowering the maintenance cost.

[0045] The dust removal method of the surface dust removal device of the electromagnetic shielding film includes the following steps:

[0046] S1: When using this device, first install this device at the designated position, and then install the shielding film 1081 on this device. Start the first motor 102 and the second motor 109. The first motor 102 will drive the two driven rollers 106 to rotate through the winding roller 103, and the second motor 109 will drive the adhesion roller 110 to rotate;

[0047] S2: After the adhesion roller 110 rotates to contact the surface of the shielding film 1081, it will be pressed into the interior of the driven roller 106 by a certain distance. When the adhesion roller 110 moves to contact the surface of the scraping plate 206, the dust adhered to its outer surface will be scraped off by the scraping plate 206;

[0048] S3: During the downward movement of the pressing plate 304, the air inside the fixed box 305 will be introduced into the interior of the air jet block 308. The dust will be blown and fall into the interior of the rotating sleeve 105 from the dust guide shell 309. The spiral blade 310 can convey the falling dust to the back and finally fall out from the back of the rotating sleeve 105.

[0049] A specific application of this embodiment is:

[0050] When using this device, first install the device at a specified position, then pass the shielding film 1081 through the two driven rollers 106 and the discharge roller 108 in sequence, and finally pass the left side of the shielding film 1081 through the left side of the inner wall of the housing 101 and pull the shielding film 1081 to the left. This pulling force needs to keep the shielding film 1081 always taut. At the same time, start the first motor 102 and the second motor 109. The first motor 102 will drive the winding roller 103 to rotate. At this time, a large amount of the shielding film 1081 has been wound on the surface of the winding roller 103. During the rotation of the winding roller 103, the shielding film 1081 will be conveyed to the left. During the rotation of the winding roller 103, it will also drive the two rotating sleeves 105 to rotate through the first belt 104, and then drive the two driven rollers 106 to rotate. The second motor 109 will drive the adhesion roller 110 to rotate, and the rotation direction of the adhesion roller 110 is opposite to that of the driven roller 106. During the rotation of the adhesion roller 110, it will drive several other adhesion rollers 110 to rotate through the second belt 111. It should be noted that the annular spring 115 is always in a stretched state, and it will always give the several sliding seats 113 and the rotating shaft 112 a force to move inward. Through the above design, when the adhesion roller 110 moves, the rotating shaft 112 can still tighten the second belt 111 through the force of the annular spring 115, so that the second belt 111 is always in a taut state, making the second belt 111 always able to transmit effectively. In summary, the annular spring 115 will give the several rotating shafts 112 a contracting force to approach each other through the sliding seats 113. Through this contracting force, the second belt 111 can always be in a taut state, so that when the adhesion roller 110 slides, the second belt 111 can still drive it to rotate. When the driven roller 106 drives the rotating adhesion roller 110 to rotate until the outer surface of the adhesion roller 110 contacts the surface of the shielding film 1081, the adhesion roller 110 will remove the dust on the surface of the shielding film 1081 through the adhesion force on its surface. At the same time, since the rotation direction of the adhesion roller 110 is opposite to the conveying direction of the shielding film 1081, the adhesion roller 110 will additionally apply a force against its movement to the shielding film 1081. This design can increase the contact pressure between the adhesion roller 110 and the shielding film 1081 through this counter force, making the adhesive surface of the adhesion roller more effectively capture and remove the dust and particles on the film surface, and further improving the cleaning effect;

[0051] After the adhesion roller 110 rotates to contact the surface of the shielding film 1081, the shielding film 1081 will exert a pressure on the adhesion roller 110, causing the adhesion roller 110 in contact with the shielding film 1081 to be pressed into the interior of the driven roller 106 by a certain distance. During the movement of the adhesion roller 110, it will drive the lifting frame 203 to move together through the lifting sleeve 202. The lifting frame 203 will drive the bottom plate 204 to move together and stretch the first spring 205. It should be noted that in the initial state, the first spring 205 exerts an elastic force on the adhesion roller 110, enabling it to remain in a state of protruding outside the driven roller 106. When the outer surface of the adhesion roller 110 moves into contact with the surface of the scraper 206, as the adhesion roller 110 continues to rotate, some of the dust adhered to its outer surface will be scraped off by the scraper 206. It should be noted that due to the certain adhesion ability of the adhesion roller 110, it is difficult to completely remove all the dust by scraping on the surface. However, the scraper 206 can still effectively remove a part of the dust. As the dust on the surface of the adhesion roller 110 increases, the amount of dust that the scraper 206 can scrape off will also increase accordingly. This process ensures that the surface of the adhesion roller 110 always maintains a reasonable dust quantity range, thereby preventing its adhesion ability from decreasing due to excessive dust. This dynamic balance mechanism can ensure that the adhesion roller 110 always maintains good adhesion performance during continuous operation. The scraped dust will fall into the interior of the fixed plate 201 along the surface of the scraper 206. This design can scrape off the dust adhering to the surface of the adhesion roller 110 through the scraper 206, thereby ensuring that the adhesion roller maintains good adhesion force, improving the cleaning efficiency of the dust on the surface of the shielding film 1081, and reducing the risk of cross-contamination between the adhesion roller 110 and the shielding film 1081;

[0052] During the downward movement of the above-mentioned bottom plate 204, it will also drive the pressing plate 304 to move downward together. During the movement of the pressing plate 304, it will suck the air inside the fixed plate 201 into the fixed box 305 through the air guide cavity 303, thereby causing a negative pressure inside the fixed plate 201 to suck and compress the second spring 302 of the shielding plate 301. At this time, the surface of the shielding plate 301 will be separated from the surface of the scraper 206, enabling the scraper 206 to normally scrape the dust on the surface of the adhesion roller 110. When the adhesion roller 110 is separated from the shielding film 1081, at this time, the entire lifting frame 203 will reset under the action of the first spring 205, and the shielding plate 301 will also reset and come into contact with the scraper 206 again. At this time, the scraper 206 will block the dust that has fallen into the interior of the fixed plate 201, preventing the dust from falling out of the fixed plate 201 again during the subsequent continuous rotation of the driven roller 106. This design blocks the dust that has fallen into the interior of the fixed plate 201 through the shielding plate 301, preventing the dust from being released again during subsequent operations and maintaining the cleanliness of the equipment;

[0053] During the downward movement of the pressing plate 304, it will also squeeze the air inside the fixed box 305 and push it into the air guide block 306. The air guide block 306 will pass the air into the air guide pipe 307, and the air guide pipe 307 will pass the air into the inside of the air jet block 308. The air jet block 308 will spray the air into the space formed by the fixed plate 201, the scraping plate 206, and the shielding plate 301. Thus, the dust falling into the inside of the fixed plate 201 can be pushed towards the direction close to the dust guide shell 309. The dust blown to the dust guide shell 309 will fall into the inside of the rotating sleeve 105 through the dust guide shell 309. As the rotating sleeve 105 rotates, relative rotation will occur between it and the spiral blade 310. Thus, the dust falling into the rotating sleeve 105 can be conveyed towards the back by the spiral blade 310 and finally fall out from the back of the rotating sleeve 105. This design can effectively guide the dust into the inside of the rotating sleeve 105 and finally discharge it from the inside of the rotating sleeve 105, reducing the frequency of manual cleaning and lowering the maintenance cost.
