Description

Technical Field

[0001] The present application relates to the technical field of film coating equipment, and in particular to a device for coating the surface of a color box. Background Art

[0002] In the modern packaging industry, color boxes are one of the main packaging forms for commodities. Their surface quality and aesthetics have an important impact on the overall image and market competitiveness of commodities. The coating treatment on the surface of color boxes can not only enhance the moisture-proof, anti-fouling and wear-resistant properties of color boxes, but also improve the visual effect of color boxes, making them more attractive and competitive in the market. However, the traditional color box surface coating device has a series of technical problems and urgently needs improvement and innovation.

[0003] The existing technology still has the following problems:

[0004] 1. When the traditional color box surface laminating device is laminating, the color box is easily offset when being transported on the conveyor belt, resulting in position deviation during laminating, which makes the film unable to accurately cover the surface of the color box, resulting in uneven laminating. The position deviation of the color box may cause the film to be unable to be fully utilized, resulting in material waste, and manual correction is a waste of time. In addition, dust is easily attached to the outer surface of the color box, and the outer surface of the color box often has an uneven texture, which makes it difficult to clean, forming tiny protrusions or depressions, resulting in the film being unable to fully fit the surface of the color box during laminating. This will not only reduce the overall aesthetics after lamination, but may also cause defects such as bubbles and wrinkles, affecting the overall quality of the product.

[0005] 2. In the laminating process of traditional laminating devices, the spacing of the glue rollers is difficult to adjust according to the demand for glue coating, so it cannot be adjusted according to the amount of glue coating required by the product, resulting in excessive or insufficient glue coating. In addition, the glue coating rollers are prone to tilt during long-term use, resulting in uneven glue coating, which makes the glue coated on the material uneven. Uneven coating will affect the quality of lamination or coating, and may cause glue accumulation, missing coating or uneven thickness on the product surface, reducing the durability and service life of the product.

[0006] 3. Toxic gases are produced during lamination, which can easily cause harm to workers. Various volatile organic compounds and harmful substances such as ink particles may be released during the lamination process. When these substances reach a certain concentration in the air, they will have an adverse effect on the health of workers. Summary of the invention

[0007] In order to overcome the problem that the color box is easily offset when being transported on the conveyor belt, resulting in position deviation during lamination, dust is easily attached to the outer surface of the color box, and the outer surface of the color box often has an uneven texture, which makes it difficult to clean, forming tiny protrusions or depressions, resulting in the film being unable to completely fit the surface of the color box during lamination, and the spacing of the glue rollers is difficult to adjust according to the demand for glue coating, so it cannot be adjusted according to the amount of glue coating required by the product, resulting in too much or too little glue coating, and the glue roller is prone to tilt during long-term use, resulting in uneven glue coating, so that the glue coated on the material is also uneven, and a variety of volatile organic compounds and harmful substances such as ink particles may be released during the lamination process.

[0020] 2. The use of the glue coating component effectively solves the problem that in the traditional laminating device, the spacing of the glue coating rollers is difficult to adjust according to the demand for glue coating during the laminating process, and thus cannot be adjusted according to the amount of glue coating required by the product, resulting in excessive or insufficient glue coating, and the glue coating roller is prone to tilt during long-term use, resulting in uneven glue coating, and thus the glue coated on the material is also uneven. Uneven coating will affect the quality of lamination or coating, and may cause glue accumulation, missing coating or uneven thickness on the product surface, reducing the durability and service life of the product. The present invention can adjust the spacing between the glue coating rollers through the glue coating component, which is convenient for adjustment according to the amount of glue coating, and can promptly detect when the glue coating roller is relatively tilted, which is convenient for maintenance of the glue coating roller, so that the glue coated on the color box is more uniform, thereby improving the product quality of the color box lamination.

[0021] 3. The use of exhaust components effectively solves the problem of toxic gases during lamination, which can easily cause harm to workers. Various volatile organic compounds and harmful substances such as ink particles may be released during the lamination process. When these substances reach a certain concentration in the air, they will have an adverse effect on the health of workers. The present invention can concentrate toxic gases through exhaust components to prevent them from being scattered in the workspace and causing harm to workers. BRIEF DESCRIPTION OF THE DRAWINGS

The fourth spring 687 is located between the limit plate 685 and the push plate 688. The push plate 688 is slidably connected to the dust box 684. The cleaning rod 682 fits the upper surface of the color box workpiece 7. The dust on the outer surface of the color box workpiece 7 is cleaned by the cleaning rod 682. During the transmission of the color box workpiece 7, the cleaning rod 682 is driven to transmit. The rotation of the cleaning rod 682 drives the scraper 683 to scrape the dust on the cleaning rod 682, so that the dust is scraped off. The dust box 684 is taken out of the cleaning rack 681 and the dust in the dust box 684 is cleaned regularly. The cleaning rod 682 is made of a soft material, and the adjustment and flexible extrusion of the adjustment mechanism 67 make the cleaning rod 682 flexibly roll and clean the dust in the dust box 684. The texture on the outer surface of the color box workpiece 7 is cleaned without causing scratches or wear on the outer surface of the color box workpiece 7. Compared with traditional brushing or wiping methods, flexible rolling cleaning is more gentle and can maintain the integrity and beauty of the color box surface. Flexible rolling cleaning can penetrate into the texture and gaps on the surface of the color box to effectively remove pollutants such as dust and impurities. Whether it is a smooth surface or an uneven texture, flexible rolling cleaning can easily cope with it. In addition, flexible rolling cleaning can also adjust the cleaning intensity as needed to meet the cleaning needs of different color box workpieces 7.

During the glue coating process, the gap between the first glue coating roller 84 and the second glue coating roller 85 determines the thickness and uniformity of the glue coating on the coating material. The fourth threaded rod 83 is rotated to drive the moving frame 82 to slide on the glue coating frame 81. When the fourth threaded rod 83 rotates, the fourth threaded rod 83 moves in the inner cavity of the glue coating frame 81. The movement of the glue coating frame 81 drives the moving frame 82 to move. The movement of the moving frame 82 drives the first glue coating roller 84 to move, so that the distance between the first glue coating roller 84 and the second glue coating roller 85 changes. At the same time, the movement of the moving frame 82 drives the connecting bar 813 to move. The movement of the connecting bar 813 drives the second bevel gear 810 to move, so that the fourth bevel gear 812 and the second bevel gear 810 always keep the meshing device during the movement. When coating, the operation of the first motor 814 drives the rotating rod 88 to rotate. The rotation of the rotating rod 88 drives the first bevel gear 89 to rotate. The rotation of 9 drives the third bevel gear 811 to rotate, and the rotation of the third bevel gear 811 drives the second glue coating roller 85 to rotate. At the same time, the rotation of the rotating rod 88 drives the second bevel gear 810 to rotate, and the rotation of the second bevel gear 810 drives the fourth bevel gear 812 to rotate. The rotation of the fourth bevel gear 812 drives the first glue coating roller 84 to rotate, so that the first glue coating roller 84 and the second glue coating roller 85 turn in opposite directions, so that the glue flows from the gap between the first glue coating roller 84 and the second glue coating roller 85 to the outer surface of the color box workpiece 7. The sealing gasket 87 is used to prevent the glue from overflowing from both ends of the first glue coating roller 84 and the second glue coating roller 85. The detection mechanism 86 is used to detect whether the first glue coating roller 84 and the second glue coating roller 85 remain parallel to prevent uneven coating due to inconsistent gaps.

[0046] See also Fig.12 and Fig.13 As shown, the detection mechanism 86 includes a fixed plate 861, the inner cavity of the fixed plate 861 is provided with a fifth spring 862, the inner cavity of the fixed plate 861 is slidably connected with an elastic seat 863, the inner cavity of the elastic seat 863 is slidably connected with a moving seat 864, one end of the moving seat 864 is sleeved with a sixth spring 865, the inner cavity of the elastic seat 863 is rotatably connected with a second alarm mechanism 866, one end of the moving seat 864 close to the second alarm mechanism 866 is rotatably connected with a swivel 867, a pointer 868 is fixedly installed on the outer surface of one side of the second alarm mechanism 866, and the side of the second alarm mechanism 866 away from the swivel 867 is fixed A detection strip 869 is installed, and balance bars 8610 are arranged at both ends of the detection strip 869. The fifth spring 862 is located between the inner wall of the fixed plate 861 and the elastic seat 863. The sixth spring 865 is located between the moving seat 864 and the inner wall of the elastic seat 863. The middle part of the swivel 867 and the second alarm mechanism 866 is tightly fitted. The balance bar 8610 is in close contact with the moving frame 82. The outer surface of the elastic seat 863 is provided with scale lines, and the pointer 868 points to the middle part of the scale lines. When the moving frame 82 moves, the moving frame 82 squeezes the balance bar 8610, and the balance bar 8610 drives the detection strip 869 to move. The elastic seat 863 squeezes the fifth spring 862, that is, when the mobile frame 82 is actually adjusted, the elastic seat 863 slides in the inner cavity of the fixed plate 861, and the elastic force of the fifth spring 862 is easy to keep the balance bar 8610 and the mobile frame 82 in close contact. When the first glue coating roller 84 and the second glue coating roller 85 are tilted, the mobile frame 82 exerts uneven force on the balance bar 8610 at both ends of the detection strip 869. At this time, the detection strip 869 is tilted. The tilt of the detection strip 869 drives the second alarm mechanism 866 to rotate. The rotation of the second alarm mechanism 866 drives the mobile seat 864 to squeeze the sixth spring 865. At this time, the movable seat 864 slides in the inner cavity of the elastic seat 863. At this time, the two sides of the second alarm mechanism 866 generate pressure on the swivel 867, so that the pointer 868 on the second alarm mechanism 866 rotates. The degree of deviation of the scale line of the pointer 868 on the elastic seat 863 can be observed to determine whether the first glue coating roller 84 and the second glue coating roller 85 are tilted and cause inconsistent gaps. This facilitates the maintenance of the first glue coating roller 84 and the second glue coating roller 85 when they are relatively tilted, so that the glue applied on the material is more even, thereby improving the product quality of the color box lamination.

[0047] Embodiment 2:

[0048] See also Fig.14As shown, the exhaust assembly 9 includes an exhaust box 91, the inner cavity of the exhaust box 91 is provided with an exhaust fan, the outer surface of the exhaust box 91 is sleeved with a first connecting pipe 92, the outer surface of the laminating machine body 1 is fixedly installed with a second fixing block 93, the outer surface of the second fixing block 93 is rotatably connected with a fifth threaded rod 94, the outer surface of the laminating machine body 1 is provided with a second motor 95, the output end of the second motor 95 is sleeved with the fifth threaded rod 94, the outer surface of the fifth threaded rod 94 is connected with a second slider 96 through a thread, the second slider 96 is slidably connected to the laminating machine body 1, the inner cavity of the second slider 96 is sleeved with a second connecting pipe 97, the inner cavity of the exhaust box 91 has a redundant second connecting pipe 97, so that the second connecting pipe 97 can be easily opened when the second slider 96 moves 7 can be stretched out in the inner cavity of the exhaust box 91, the second connecting pipe 97 is sleeved with the inner cavity of the exhaust box 91, and the second connecting pipe 97 is fixedly installed with an air inlet 98 at one end away from the exhaust box 91. When the color box workpiece 7 produces toxic gas during coating, the exhaust fan in the inner cavity of the exhaust box 91 drives the air inlet 98 to collect the smell into the inner cavity of the exhaust box 91, and connects to the external pipeline through the first connecting pipe 92, so that the smell is discharged to the same position for treatment, and the second motor 95 drives the second slider 96 to move on the fifth threaded rod 94, and the movement of the second slider 96 drives the second connecting pipe 97 to move, and the movement of the second connecting pipe 97 drives the air inlet 98 to move, thereby improving the flexibility of the air inlet 98 and facilitating the discharge of the dispersed gas.

[0049] In summary, when the color box workpiece 7 is coated, it is transported through the first conveyor belt 2, and the position of the color box workpiece 7 is corrected when passing through the correction component 6, and the outer surface of the color box workpiece 7 is cleaned at the same time. The gluing component 8 is used to glue the color box workpiece 7, and the heating roller 4 is used to heat the color box workpiece 7. The film on the film roll 10 passes through the pressure roller 5 and is coated on the upper surface of the color box workpiece 7. The pressure roller 5 is used to exert a certain pressure on the film to play a role in leveling and removing bubbles. The exhaust component 9 is used to discharge the polluted gas generated during the coating, so that the gas is discharged at a fixed point for treatment, which has an environmental protection effect. It is guided by the guide rod 611 on the correction block 610, and when the color box workpiece 7 deviates, it drives the adjustment The node block 69 is offset, and the offset of the adjustment block 69 drives the correction frame 62 to offset. The offset of the correction frame 62 drives the slide bar 63 to slide in the inner cavity of the fixed frame 61, and the correction frame 62 is restored to its original position under the elastic force of the first spring 65. Even if it is subjected to external force, the correction frame 62 will eventually return to the far position, thereby driving the guide rod 611 to restore its original position, so that the color box workpiece 7 is transmitted as a whole in the middle part of the first conveyor belt 2. The first threaded rod 64 is rotated to drive the adjustment block 69 to slide on the correction frame 62, so as to facilitate the adjustment of the spacing between the adjustment blocks 69, so that the color box workpiece 7 just passes through the spacing between the parallel parts of the correction block 610. The first alarm mechanism 66 is used to sound an alarm when an offset occurs, which plays a detection role. The cleaning mechanism 68 is used to clean the outer surface of the color box workpiece 7, and the strength of the cleaning mechanism 68 on the color box workpiece 7 is adjusted by the adjustment mechanism 67, so that the cleaning mechanism 68 has a flexible strength during cleaning, which is convenient for cleaning the uneven texture of the outer surface of the color box workpiece 7. The amount of glue is adjusted by adjusting the gap between the first glue coating roller 84 and the second glue coating roller 85. During the gluing process, the gap between the first glue coating roller 84 and the second glue coating roller 85 determines the thickness and uniformity of the glue coating on the coating material. The spacing between the first glue coating roller 84 and the second glue coating roller 85 is changed by rotating the fourth threaded rod 83. At the same time, the movement of the movable frame 82 drives the connecting strip 813 to move, and the movement of the connecting strip 813 The second bevel gear 810 is driven to move, so that the fourth bevel gear 812 and the second bevel gear 810 always maintain a meshing device during the movement. When applying glue, the operation of the first motor 814 drives the second glue roller 85 to rotate. At the same time, the rotation of the rotating rod 88 drives the first glue roller 84 to rotate, so that the first glue roller 84 and the second glue roller 85 turn in opposite directions, so that the glue flows from the gap between the first glue roller 84 and the second glue roller 85 to the outer surface of the color box workpiece 7. The sealing gasket 87 is used to prevent the glue from overflowing from both ends of the first glue roller 84 and the second glue roller 85. The detection mechanism 86 is used to detect whether the first glue roller 84 and the second glue roller 85 remain parallel to prevent uneven coating due to inconsistent gaps.
