Technical Field

[0001] The invention belongs to the technical field of plate film pressing, in particular to a plate processing film pressing device. Background Art

[0002] Sheet lamination is a processing technology mainly used in the production of cabinet door panels in home customization. This process involves covering the surface of the sheet with a layer of PVC film, and using a laminator to tightly fit the film on the sheet to form an integrated decorative layer. Cabinet door panels made by lamination have many advantages, including good waterproof performance, environmental protection, and diverse shapes and color textures, so they are widely used in home decoration. In addition, laminated boards also have the characteristics of no cracking, no deformation, and easy cleaning, making maintenance simple and having a good cost-effectiveness.

[0003] Laminator is a device used to laminat various materials. It is widely used in different industries, including but not limited to the production of cabinet door panels in home customization. The main functions of laminator include laminating materials, which can improve the appearance and durability of materials; When using a laminator to laminat e a sheet, firstly, the sheet needs to be placed on the conveyor roller of the laminator. The rotating conveyor roller will drive the sheet to move, and at the same time, the feeding system will be used to convey the film from the film roller to the laminating area. During this period, the film will pass through the feeding roller. When the moving sheet passes through the laminating area, the pressing roller will press the film onto the sheet, thereby laminating the sheet. When laminating the sheet, since the film is transferred from the film roller to the laminating area, if external dust or impurities fall on the film or the sheet and are not cleaned in time, the impurities or dust will be wrapped between the film and the sheet, causing the film on the surface of the sheet to form bulges, thereby affecting the appearance of defects in the sheet after lamination.

When the sheet conveying system is working, it controls the evenly arranged driving rollers 12 to rotate, and then the external conveyor belt drives the sheet 13 to be laminar to move, and the sheet 13 gradually moves onto the driving roller 12. When the sheet 13 moves onto the driving roller 12, the sheet 13 first contacts the curved side of the guide plates 5 on both sides, and then gradually moves to the two guide plates 5. The two guide plates 5 will move away from each other. In the process of the guide plates 5 moving away from each other, the guide rod will be pushed to slide on the mounting plate 11. At the same time, the guide plates 5 will squeeze the spring. When the plate 13 moves between the two guide plates 5, the two guide plates 5 will fit with the side of the plate 13, so that the plate 13 can be corrected to prevent the plate 13 from moving with the driving roller 12 in an inclined state, and to prevent the film 23 from being misaligned with the plate 13, resulting in the film 23 not being properly fitted on the plate 13, thereby affecting the quality of the plate 13 after filming; More specifically, when the plate 13 gradually passes through the guide plate 5, the plate 13 will gradually enter under the dust removal plate 4. After the plate 13 enters under the dust removal plate 4, the plate 13 will gradually contact the rubber rings 44 on the evenly arranged rollers 43, and the rollers 43 will be driven to rotate during the movement of the plate 13. When the plate 13 moves to the position of the air groove 45, the blocking layer 46 can scrape the surface of the plate 13, thereby blocking impurities or dust on the surface of the plate 13 to prevent the impurities or dust from moving with the plate 13. Since there are multiple blocking layers 46, when the plate 13 passes through each blocking layer 46, the blocking layer 46 will scrape the plate 13, thereby removing dust or Impurities are blocked. Since the external air pump continuously evacuates the air cavity 41, the gas under the air groove 45 will enter the air cavity 41 through the air groove 45 and then be pumped out by the air pump. In this process, the dust blocked by the blocking layer 46 can be pumped into the air cavity 41 and then discharged with the air pump, so that the blocked dust can be discharged, avoiding that the impurities or dust blocked by the blocking layer 46 cannot be discharged, resulting in the gradual increase of the blocked dust to form accumulation and block the air groove 45. At the same time, it can be prevented that some impurities or dust will move with the plate 13, so that the part of the impurities or dust will be coated between the film 23 and the plate 13, resulting in the film 23 on the surface of the plate 13 forming a bulge, thereby affecting the appearance of defects on the plate 13 after lamination; Furthermore, after the sheet 13 passes through the dust removal plate 4, the sheet 13 will gradually move to the position below the film bin 2 under the drive of the driving roller 12, and the moving sheet 13 will fit with the bottom end surface of the film bin 2, and then move toward the film pressing assembly position. When the sheet 13 moves to the position of the first pressing roller 32, the servo motor 22 drives the film roller 21 to rotate and gradually releases the film 23. When the sheet 13 passes under the first pressing roller 32, it can drive the first pressing roller 32 to rotate. The rotating first pressing roller 32 can press the released film 23 onto the sheet 13. At the same time, the first rotating roller 43 can press out the gas between the film 23 and the sheet 13 to avoid the existence of gas between the film 23 and the sheet 13, thereby causing bubbles to appear on the film 23 of the sheet 13 after film pressing. Furthermore, since the film 23 extends from the conveying groove 25 on the film bin 2 to the position of the first pressing roller 32, the film 23 extending from the conveying groove 25 can be directly attached to the plate 13, thereby avoiding the need to pull the film 23 from the film roller 21 to the film pressing area when attaching the film to the plate 13, thereby reducing the distance that the film 23 is pulled out from the film roller 21, thereby reducing the risk of foreign matter adhering to the film 23. At the same time, since a closed bin 33 is fixedly installed above the first notch 31, the closed bin 33 can A notch 31 is avoided, thereby further preventing external dust from entering through the first notch 31 and adhering to the film 23, thereby causing dust or impurities to be wrapped between the film 23 and the plate 13; when the plate 13 passes through the first pressure roller 32, the plate 13 will gradually pass under the evenly arranged second pressure roller 35. When the plate 13 passes under the evenly arranged second pressure roller 35, the first pressure roller 32 can squeeze the plate 13, thereby squeezing the film 23, so that the film 23 can fit more firmly on the plate 13.

[0019] Embodiment 2: The support column 24 includes a fixed cylinder 241 and a sliding column 242; the fixed cylinder 241 is fixedly installed on the frame 1; the sliding column 242 is fixedly installed at the bottom of the film bin 2; The sliding column 242 slides in the fixed cylinder 241; a spring is fixedly connected to the bottom of the sliding column 242, and the other side of the spring is connected to the fixed cylinder 241; In this embodiment, the film bin 2 includes a film cylinder 201 and two side plates 202; Side plates 202 are installed on both sides of the film cylinder 201 by bolts; U-shaped grooves are opened on the mounting plate 11 below the two side plates 202; a servo motor 22 is installed on one of the side plates 202, and a rectangular block 221 is installed on the output shaft of the servo motor 22; A rectangular groove 211 is formed on one side of the film roller 21 close to the servo motor 22, and the rectangular block 221 is inserted into the rectangular groove 211; the side of the film roller 21 without the rectangular groove 211 passes through the other side plate 202; Specifically, when it is necessary to press the sheets 13 of different thicknesses, when the driving roller 12 pushes the sheet 13 to move to the position of the dust removal plate 4, since the side of the dust removal plate 4 away from the film bin 2 is bent upward, the sheet 13 will first contact the side of the dust removal plate 4 that is bent upward, and as the sheet 13 continues to move, the dust removal plate 4 will gradually be pushed upward, and at the same time, the dust removal plate 4 will drive the film bin 2 to move upward in the U-shaped groove, and the film bin 2 will drive the sliding column 242 to move upward in the fixed cylinder 241, and lengthen the connecting sliding column 242 and the spring of the fixing cylinder 241, when the plate 13 moves to the bottom of the dust removal plate 4, the dust removal plate 4 will no longer move up, and at the same time the film cylinder 201 will not drive the pressing plate 3 to move up, and then the plate 13 will pass through the film cylinder 201 to be laminated, and then the laminating assembly will complete the laminating, so when it is necessary to laminate the plates 13 of different thicknesses, the plate 13 can push the dust removal plate 4 and the film bin 2 to move up, so as to adapt to the thickness of the plates 13 of different thicknesses, so that the plates 13 of different thicknesses can be laminated; When it is necessary to laminate films on plates 13 of different widths, it is necessary to replace the film 23 that matches the width of the plate 13. First, use a wrench to remove the side plate 202 on which the servo motor 22 is not installed from the film tube 201, then take the film roller 21 out of the film tube 201, and then replace it with a new film roller 21. When installing the new film roller 21, first insert the film roller 21 into the film tube 201, then align the rectangular groove 211 opened on the film roller 21 with the rectangular block 221, and insert the rectangular block 221 into the rectangular groove 211, then pass the other end of the film roller 21 through the side plate 202, and fasten the side plate 202 to the film tube 201 with bolts. Therefore, by replacing films 23 of different widths, plates 13 of different widths can be laminated.

[0020] Embodiment 3: The outer surface of the rubber ring 44 is provided with evenly arranged tooth grooves 441; The rubber layer is rotatably connected to the air groove 45 by a toothed belt 47, and the toothed belt 47 is meshed with the toothed groove 441; A cleaning roller 48 is rotatably connected in the air groove 45, and a cleaning layer 49 is evenly arranged fixedly connected to the surface of the cleaning roller 48, and the cleaning layer 49 is meshed with the toothed belt 47; In this embodiment, the film tube 201 is provided with evenly arranged through holes 203 on one side facing the dust removal plate 4, and the through holes 203 are connected to the air cavity 41 in the dust removal plate 4; A one-way valve is installed in each of the through holes 203, and the gas in the film tube 201 can only enter the air cavity 41 through the through holes 203; In this embodiment, a wiping layer 204 is fixedly connected to the plane at the bottom of the film tube 201; Specifically, when the plate 13 passes through the rubber ring 44, the plate 13 will drive the rubber ring 44 and the roller 43 to rotate counterclockwise. During the counterclockwise rotation of the rubber ring 44, the evenly arranged tooth grooves 441 will be driven to rotate. Since the tooth grooves 441 are meshed with the tooth belt 47, the tooth belt 47 will be driven to rotate clockwise. The clockwise rotating tooth belt 47 will push the cleaning layer 49 on the cleaning roller 48 to rotate counterclockwise. When the cleaning layer 49 rotates, it will push the blocking layer 46 to block the dust or impurities from moving along the blocking layer 46, thereby transferring the dust or impurities into the air cavity 41, and then being pumped away by the external air pump. In this process, it can be avoided that the external air pump cannot completely pump out the dust or impurities on the plate 13, resulting in some impurities or dust still remaining on the surface of the plate 13. Since the through hole 203 on the film tube 201 is connected to the air cavity 41, and a one-way valve is installed in the air cavity 41, when the external air pump draws out the gas in the air cavity 41, the gas in the film tube 201 is also drawn into the air cavity 41 from the through hole 203, so that the dust or impurities remaining in the film tube 201 can be drawn out, and the dust or impurities in the film tube 201 can be prevented from adhering to the surface of the film 23 and being attached to the plate 13; Since the plane at the bottom of the film tube 201 is fixedly connected with the wiping layer 204, the plate 13 will pass through the wiping layer 204 before being laminated. When the plate 13 passes through the wiping layer 204, the wiping layer 204 will wipe the surface of the plate 13 again, thereby avoiding the presence of impurities or dust on the surface of the plate 13, which will affect the quality of the plate 13 after lamination.
