Description

Technical Field

[0001] This application relates to the technical field of film laminating equipment, and particularly to a color box surface film laminating device. Background Art

[0002] In the modern packaging industry, as one of the main packaging forms of commodities, the surface quality and aesthetics of color boxes have an important impact on the overall image and market competitiveness of commodities. The film laminating 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, there are a series of technical problems in traditional color box surface film laminating devices, which urgently need to be improved and innovated.

[0003] Currently, the following problems still exist in the existing technology:

[0004] 1. When the traditional color box surface film laminating device performs film laminating, since the color box is prone to deviation during transportation on the conveyor belt, the position deviates during film laminating, resulting in the film being unable to accurately cover the surface of the color box, causing uneven film lamination. The deviation of the color box position may cause the film not to be fully utilized, resulting in material waste. Manual correction is time-consuming. In addition, dust is easily attached to the outer surface of the color box, and there are often uneven textures on the outer surface of the color box, making it difficult to clean, forming small protrusions or depressions, resulting in the film not being able to fully adhere to the surface of the color box during film laminating. This will not only reduce the overall aesthetics after film laminating, but may also produce defects such as bubbles and wrinkles, affecting the overall quality of the product.

[0005] 2. During the film laminating process of the traditional film laminating device, the distance between the glue coating rollers is difficult to adjust according to the glue coating requirements, so it cannot be adjusted according to the amount of glue required by the product, resulting in too much or too little glue coating. Moreover, the glue coating rollers are prone to tilt during long-term use, resulting in uneven glue coating, so that the glue coated on the material is also uneven. Uneven coating will affect the quality of film laminating or coating, and may cause phenomena such as glue accumulation, missed coating or uneven thickness on the product surface, reducing the durability and service life of the product.

[0006] 3. Toxic gases are generated during film laminating, which are likely to cause harm to workers. During the film laminating process, various volatile organic compounds, as well as harmful substances such as ink particles, may be released. When these substances reach a certain concentration in the air, they will have an adverse impact on the health of workers. Summary of the Invention

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. Due to the adoption of a correction component, it effectively solves the problems in the traditional color box surface film laminating device during the film laminating process. When the color box is transported on the conveyor belt, it is prone to deviation, resulting in position deviation during film laminating. As a result, the film cannot be accurately covered on the surface of the color box, causing uneven film lamination. The deviation of the color box position may lead to incomplete utilization of the film, resulting in material waste, and manual correction is time-consuming. In addition, dust is easily attached to the outer surface of the color box, and the outer surface of the color box often has uneven textures, making it difficult to clean, forming small protrusions or depressions, resulting in the film not being able to fit perfectly with the surface of the color box during film laminating. This not only reduces the overall aesthetics after film laminating but may also cause defects such as bubbles and wrinkles, affecting the overall quality of the product. Through the correction component, the position of the color box can be flexibly corrected, making the film laminating position accurate, avoiding waste of raw materials, and being able to issue an alarm when the position of the color box deviates. In addition, the outer surface of the color box can be dusted. The flexible rolling cleaning can penetrate into the textures and gaps on the surface of the color box, effectively removing pollutants such as dust and impurities. The flexible rolling cleaning can also adjust the cleaning intensity according to needs.

[0020] 2. Due to the adoption of a glue coating component, it effectively solves the problems in the traditional film laminating device during the film laminating process. It is difficult to adjust the spacing between the glue coating rollers according to the glue coating requirements, so it cannot be adjusted according to the amount of glue needed for the product, resulting in too much or too little glue coating. Moreover, the glue coating rollers are 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 film laminating or coating, and may cause phenomena such as glue accumulation, missed coating, or uneven thickness on the product surface, reducing the durability and service life of the product. Through the glue coating component, the spacing between the glue coating rollers can be adjusted, facilitating adjustment according to the amount of glue coating, and being able to detect in time when the glue coating rollers are relatively tilted, facilitating maintenance of the glue coating rollers, making the glue coated on the color box more uniform, and improving the product quality of color box film laminating.

[0021] 3. Due to the adoption of an exhaust component, it effectively solves the problem that toxic gases are present during film laminating, which is likely to cause harm to the staff. During the film laminating process, various volatile organic compounds, as well as harmful substances such as ink particles, may be released. When these substances reach a certain concentration in the air, they will have an adverse impact on the health of the staff. Through the exhaust component, the toxic gases can be concentrated, preventing them from spreading in the working space and causing harm to the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] When the color box is transported on the conveyor belt, it is prone to deviation, resulting in deviation of the position during laminating. The present invention can flexibly correct the position of the color box through the correction component, making the laminating position accurate and avoiding waste of raw materials. For the distance between the glue coating rollers, it is difficult to adjust according to the required amount of glue coating. The present invention can adjust the distance between the glue coating rollers through the glue coating component, facilitating adjustment according to the amount of glue coating. During the laminating process, toxic gases may be released. The present invention can concentrate the toxic gases through the exhaust component.

[0038] In order to better understand the above technical solutions, the following will explain the above technical solutions in detail in combination with the specification drawings and specific implementation modes.

The heating roller 4 is located between the first conveyor belt 2 and the second conveyor belt 3. The second conveyor belt 3 is used to convey the workpiece after film laminating away. A pressure roller 5 is rotatably connected to the inner wall of the film laminating machine main body 1. A correction component 6 is fixedly installed on the upper surface of the film laminating machine main body 1. The correction component 6 is located above the first conveyor belt 2. A color box workpiece 7 is placed on the upper surface of the first conveyor belt 2. A glue coating component 8 is fixedly installed on the inner wall of the film laminating machine main body 1. Exhaust components 9 are arranged on the outer surfaces on both sides of the film laminating machine main body 1. A film roll 10 is rotatably connected to the inner wall of the film laminating machine main body 1. When laminating the color box workpiece 7, it is transmitted through the first conveyor belt 2. When passing through the correction component 6, the position of the color box workpiece 7 is corrected, and at the same time, the outer surface of the color box workpiece 7 is cleaned. The glue coating component 8 is used to apply glue to the color box workpiece 7. The heating roller 4 is used to heat the color box workpiece 7. The film on the film roll 10 is passed through the pressure roller 5 and laminated on the upper surface of the color box workpiece 7. The pressure roller 5 is used to apply a certain pressure to the film, playing a role in leveling and removing bubbles. The exhaust components 9 are used to discharge the polluted gas generated during film laminating, enabling the gas to be discharged and treated at a fixed point, achieving an environmental protection effect.

[0041] Please refer to Figure 3 and Figure 4As shown in the figure, the correction component 6 includes a fixed frame 61. Below the fixed frame 61, there is a correction frame 62. At both ends of the correction frame 62, there are fixed sliding rods 63. Inside the cavity of the correction frame 62, there is a first threaded rod 64 rotatably connected. At both ends of the sliding rod 63, there is a first spring 65 sleeved. On the outer surface of the fixed frame 61, there is a first alarm mechanism 66. At the lower surface of the fixed frame 61, there is an adjustment mechanism 67 fixedly installed. At the bottom end of the adjustment mechanism 67, there is a cleaning mechanism 68.

The adjustment block 69 and the first threaded rod 64 are connected by threads, and the thread directions at both ends of the first threaded rod 64 are opposite. The adjustment block 69 and the correction frame 62 are slidably connected. The first spring 65 is located between the inner wall of the fixed frame 61 and the correction frame 62. The sliding rod 63 and the fixed frame 61 are slidably connected. There are two correction blocks 610, and the openings of the correction blocks 610 are first parallel and then increase, and the parallel ends are close to the middle part of the laminating machine main body 1. The bottom end of the guide rod 611 is in contact with the upper surface of the laminating machine main body 1. When the color box workpiece 7 passes through the guide rod 611, it is guided by the guide rod 611 on the correction block 610. And when the color box workpiece 7 is offset, it drives the adjustment block 69 to generate an offset. The offset of the adjustment block 69 drives the correction frame 62 to offset. The offset of the correction frame 62 drives the sliding rod 63 to slide in the cavity of the fixed frame 61. Under the elastic force of the first spring 65, the correction frame 62 returns to its original position, realizing flexible correction and protecting the side of the workpiece. Even when subjected to an external force, the correction frame 62 will finally return to a far position, thereby driving the guide rod 611 to return to its original position, so that the entire color box workpiece 7 is transported in the middle part of the first conveyor belt 2. By rotating the first threaded rod 64, the adjustment block 69 is driven to slide on the correction frame 62, facilitating the adjustment of the distance between the adjustment blocks 69, so that the color box workpiece 7 just passes through the distance between the parallel parts of the correction blocks 610. The first alarm mechanism 66 is used to give an alarm when an offset occurs, playing a detection role. The cleaning mechanism 68 is used to clean the outer surface of the color box workpiece 7, and the cleaning mechanism 68 adjusts the force on the color box workpiece 7 through the adjustment mechanism 67, so that the cleaning mechanism 68 has a flexible force during cleaning, facilitating the cleaning of the uneven texture on the outer surface of the color box workpiece 7.

[0042] Please refer to Figure 5 and Figure 6As shown, the first alarm mechanism 66 includes a connecting frame 661.

A first connecting block 665 is fixedly installed at the middle part of the correction frame 62. A pressure rod 666 is fixedly installed on the outer surface of the top end of the first connecting block 665. The pressure rod 666 is flush with the first button 664. A first alarm 667 is fixedly installed on the outer surface of the fixed frame 61. The first button 664 is electrically connected to the first alarm 667. Pressing the first button 664 controls the first alarm 667 to sound an alarm. The middle part of the fixed frame 61 is a cavity, and the first connecting block 665 is located at the cavity of the fixed frame 61. When the correction frame 62 is offset, it drives the first connecting block 665 to move. The movement of the first connecting block 665 drives the pressure rod 666 to contact the first button 664. The first button 664 causes the first alarm 667 to sound an alarm under the pressure of the pressure rod 666, reminding the staff that the correction frame 62 is offset, that is, the color box workpiece 7 is offset and drives the correction frame 62 to be offset. By rotating the second threaded rod 662 on the connecting frame 661, the first slider 663 is driven to slide in the inner cavity of the connecting frame 661, so that the distance between the first button 664 on the first slider 663 and the pressure rod 666 changes. In this way, the alarm distance can be set according to the offset amount of the correction frame 62 for early warning.

[0043] Please refer to Figure 7 and Figure 8As shown, the adjustment mechanism 67 includes a first fixed block 671, the first fixed block 671 is fixedly connected to the fixing frame 61, the inner cavity of the first fixed block 671 is rotatably connected to the third threaded rod 672, the lower surface of the first fixed block 671 is slidably connected to the driving block 673, the driving block 673 and the third threaded rod 672 are connected by threads, the outer surface of the driving block 673 is fixedly installed with a driving rod 674, the four corners of the first fixed block 671 are fixedly installed with a storage rod 675, the inner cavity of the storage rod 675 is slidably connected to the telescopic rod 676, and the bottom end of the telescopic rod 676 is fixedly installed with The lifting block 677 is fixedly mounted with a second connecting block 678 on the upper surface of the lifting block 677.

The buffer rod 6710 and the lifting block 677 are slidably connected. The outer surface of the buffer rod 6710 is sleeved with a third spring 6711. The bottom end of the buffer rod 6710 is fixedly mounted with a connecting rod 6712. The third spring 6711 is located at the lifting block. The cleaning force of the cleaning mechanism 68 on the color box workpiece 7 is adjusted between 677 and the connecting rod 6712 through the adjustment mechanism 67. The third threaded rod 672 is rotated to drive the driving block 673 to slide on the first fixed block 671. The sliding of the driving block 673 drives the driving rod 674 to slide in the inclined groove on the second connecting block 678, thereby moving the lifting block 677. The movement of the lifting block 677 drives the telescopic rod 676 to slide in the inner cavity of the storage rod 675, so that the height of the connecting rod 6712 changes, thereby changing the squeezing force of the cleaning mechanism 68 on the color box workpiece 7, and when the color box workpiece 7 is not The smoothing makes the connecting rod 6712 flexible. When the cleaning mechanism 68 contacts the outer surface of the color box workpiece 7, the texture of the outer surface of the color box workpiece 7 will drive the connecting rod 6712 to shake slightly, which is convenient for cleaning the texture of the outer surface of the color box workpiece 7. The pressure of the connecting rod 6712 drives the third spring 6711 to compress. At this time, the buffer rod 6710 drives the buffer tube 679 to slide in the inner cavity of the lifting block 677, so that the cleaning mechanism 68 has a flexible effect when cleaning the color box workpiece 7, and can penetrate into the texture and gaps on the surface of the color box to effectively remove dust, impurities and other pollutants.

[0044] See also Figure 8 and Figure 9As shown, the cleaning mechanism 68 includes a cleaning frame 681. The cleaning frame 681 is fixedly connected to the connecting rod 6712. A cleaning rod 682 is rotatably connected to the inner wall of the cleaning frame 681. A scraping piece 683 is fixedly installed on one side of the cleaning frame 681 close to the cleaning rod 682. A dust collection box 684 is arranged in the inner cavity of the cleaning frame 681. Slots are opened at both ends of the cleaning frame 681. Limit plates 685 are fixedly installed at both ends of the dust collection box 684. A plug rod 686 is slidably connected to the inner cavity of the limit plate 685. The plug rod 686 passes through the dust collection box 684 and is inserted into the slot on the cleaning frame 681. A fourth spring 687 is sleeved on the outer surface of the plug rod 686. A push plate 688 is fixedly installed on the outer surface of the plug rod 686. 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 collection box 684. The cleaning rod 682 is in contact with 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 rotate. The rotation of the cleaning rod 682 drives the scraping piece 683 to scrape the dust on the cleaning rod 682, so that the dust enters the inner cavity of the dust collection box 684 from the scraping piece 683. When the dust accumulates to a certain amount, by pulling the push plate 688, the push plate 688 squeezes the fourth spring 687. At this time, the push plate 688 drives the plug rod 686 to slide in the inner cavity of the limit plate 685. The plug rod 686 is disengaged from the slot on the cleaning frame 681, and the whole dust collection box 684 is taken out, which is convenient for regularly cleaning the dust in the inner cavity of the dust collection box 684. The cleaning rod 682 is made of a soft material. With the adjustment of the adjustment mechanism 67 and the flexible extrusion, the cleaning rod 682 cleans the texture on the outer surface of the color box workpiece 7 in a flexible rolling cleaning manner, and will not cause scratches or abrasions to the outer surface of the color box workpiece 7. Compared with the traditional brushing or wiping method, the flexible rolling cleaning is more gentle and can maintain the integrity and beauty of the color box surface. The flexible rolling cleaning can penetrate into the texture and gaps on the color box surface and effectively remove pollutants such as dust and impurities. Whether it is a smooth surface or an uneven texture, the flexible rolling cleaning can easily handle it. In addition, the flexible rolling cleaning can also adjust the cleaning intensity according to needs to meet the cleaning requirements of different color box workpieces 7.

[0045] Please refer to Figure 10 and Figure 11As shown in the figure, the glue application component 8 includes a glue application rack 81. A moving rack 82 is slidably connected to the upper surface of the glue application rack 81. A fourth threaded rod 83 is rotationally connected to the inner cavity of the glue application rack 81 through a thread. A first glue application roller 84 is rotationally connected to the inner cavity of the moving rack 82. A second glue application roller 85 is rotationally connected to the inner cavity of the glue application rack 81. A detection mechanism 86 is fixedly installed on the upper surface of the glue application rack 81. Sealing gaskets 87 are provided at the junctions of both ends of the first glue application roller 84 and the second glue application roller 85. A rotating rod 88 is rotationally connected to the inner cavity of the glue application rack 81. A first bevel gear 89 is fixedly connected to the outer surface of the rotating rod 88. A second bevel gear 810 is slidably connected to the outer surface of the rotating rod 88. A third bevel gear 811 is fixedly connected to one end of the second glue application roller 85. A fourth bevel gear 812 is fixedly installed at one end of the first glue application roller 84. A connecting strip 813 is fixedly installed at one end of the moving rack 82. A first motor 814 is provided on the outer surface of the glue application rack 81. The first bevel gear 89 and the third bevel gear 811 are meshed. The second bevel gear 810 and the fourth bevel gear 812 are meshed. The second bevel gear 810 is rotationally connected to the connecting strip 813. The output end of the first motor 814 is sleeved on the rotating rod 88. The fourth threaded rod 83 is rotationally connected to the moving rack 82. The first glue application roller 84 and the second glue application roller 85 are in contact. The amount of glue applied is adjusted by adjusting the gap between the first glue application roller 84 and the second glue application roller 85. During the glue application process, the gap between the first glue application roller 84 and the second glue application roller 85 determines the thickness and uniformity of the glue coating on the coating material. By rotating the fourth threaded rod 83, the moving rack 82 is driven to slide on the glue application rack 81. When the fourth threaded rod 83 rotates, the fourth threaded rod 83 moves in the inner cavity of the glue application rack 81. The movement of the glue application rack 81 drives the movement of the moving rack 82. The movement of the moving rack 82 drives the movement of the first glue application roller 84, so that the distance between the first glue application roller 84 and the second glue application roller 85 changes. At the same time, the movement of the moving rack 82 drives the movement of the connecting strip 813. The movement of the connecting strip 813 drives the movement of the second bevel gear 810, so that the fourth bevel gear 812 and the second bevel gear 810 always remain meshed during the movement. When applying glue, the operation of the first motor 814 drives the rotation of the rotating rod 88. The rotation of the rotating rod 88 drives the rotation of the first bevel gear 89. The rotation of the first bevel gear 89 drives the rotation of the third bevel gear 811. The rotation of the third bevel gear 811 drives the rotation of the second glue application roller 85. At the same time, the rotation of the rotating rod 88 drives the rotation of the second bevel gear 810. The rotation of the second bevel gear 810 drives the rotation of the fourth bevel gear 812. The rotation of the fourth bevel gear 812 drives the rotation of the first glue application roller 84, making the rotation directions of the first glue application roller 84 and the second glue application roller 85 opposite. Thus, the glue flows into the outer surface of the color box workpiece 7 from the gap between the first glue application roller 84 and the second glue application roller 85. The sealing gasket 87 is used to prevent the glue from overflowing from both ends of the first glue application roller 84 and the second glue application roller 85. The detection mechanism 86 is used to detect whether the first glue application roller 84 and the second glue application roller 85 are kept parallel, preventing uneven coating caused by inconsistent gaps.

[0046] Please refer to Figure 12 and Figure 13 As shown, the detection mechanism 86 includes a fixing plate 861. A fifth spring 862 is arranged in the inner cavity of the fixing plate 861. A elastic seat 863 is slidably connected in the inner cavity of the fixing plate 861. A moving seat 864 is slidably connected in the inner cavity of the elastic seat 863. A sixth spring 865 is sleeved at one end of the moving seat 864. A second alarm mechanism 866 is rotatably connected in the inner cavity of the elastic seat 863. A rotating ring 867 is rotatably connected at one end of the moving seat 864 close to the second alarm mechanism 866. A pointer 868 is fixedly installed on the outer surface of one side of the second alarm mechanism 866. A detection strip 869 is fixedly installed on the side of the second alarm mechanism 866 far from the rotating ring 867. 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 fixing 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 parts of the rotating ring 867 and the second alarm mechanism 866 are in close contact. The balance bars 8610 and the moving frame 82 are in close contact. Scale lines are arranged on the outer surface of the elastic seat 863, and the pointer 868 points to the middle part of the scale lines. When the moving frame 82 moves, the moving frame 82 presses the balance bars 8610. The balance bars 8610 drive the detection strip 869 to move, so that the elastic seat 863 squeezes the fifth spring 862. That is, when the moving frame 82 is actually adjusted, the elastic seat 863 slides in the inner cavity of the fixing plate 861. Under the elastic force of the fifth spring 862, it is convenient to keep the balance bars 8610 and the moving frame 82 in close contact. When the first glue applicator roller 84 and the second glue applicator roller 85 are inclined, the forces on the balance bars 8610 at both ends of the detection strip 869 by the moving frame 82 are uneven. At this time, the detection strip 869 is inclined. The inclination of the detection strip 869 drives the second alarm mechanism 866 to rotate. The rotation of the second alarm mechanism 866 drives the moving seat 864 to squeeze the sixth spring 865. At this time, the moving seat 864 slides in the inner cavity of the elastic seat 863. At this time, pressures are generated on both sides of the second alarm mechanism 866 on the rotating ring 867. Thus, the pointer 868 on the second alarm mechanism 866 rotates. It can be judged whether the first glue applicator roller 84 and the second glue applicator roller 85 are inclined and the gaps are inconsistent by observing the offset degree of the pointer 868 on the scale lines of the elastic seat 863. It is convenient to maintain the first glue applicator roller 84 and the second glue applicator roller 85 when the first glue applicator roller 84 and the second glue applicator roller 85 are relatively inclined, so that the glue coated on the material is more uniform and the product quality of the color box film coating is improved.

[0047] Embodiment 2:

[0048] Please refer to Figure 14As shown in the figure, the exhaust component 9 includes an exhaust air box 91. An exhaust fan is arranged in the inner cavity of the exhaust air box 91. A first connecting pipe 92 is sleeved on the outer surface of the exhaust air box 91. A second fixing block 93 is fixedly installed on the outer surface of the laminating machine main body 1. A fifth threaded rod 94 is rotatably connected to the outer surface of the second fixing block 93. A second motor 95 is arranged on the outer surface of the laminating machine main body 1. The output end of the second motor 95 is sleeved with the fifth threaded rod 94. A second slider 96 is threadedly connected to the outer surface of the fifth threaded rod 94. The second slider 96 is slidably connected to the laminating machine main body 1. A second connecting pipe 97 is sleeved in the inner cavity of the second slider 96. There is an excess of the second connecting pipe 97 in the inner cavity of the exhaust air box 91, so that the second connecting pipe 97 can be stretched out from the inner cavity of the exhaust air box 91 when the second slider 96 moves. The second connecting pipe 97 is sleeved in the inner cavity of the exhaust air box 91. One end of the second connecting pipe 97 far away from the exhaust air box 91 is fixedly installed with an air inlet 98. When toxic gases are generated during the lamination of the color box workpiece 7, the operation of the exhaust fan in the inner cavity of the exhaust air box 91 drives the air inlet 98 to collect the odor into the inner cavity of the exhaust air box 91. The odor is discharged to the same position for treatment through the first connecting pipe 92 communicating with an external pipeline. The operation of the second motor 95 drives the second slider 96 to move on the fifth threaded rod 94. The movement of the second slider 96 drives the second connecting pipe 97 to move. The movement of the second connecting pipe 97 drives the air inlet 98 to move, improving the flexibility of the air inlet 98 and facilitating the discharge of the dispersed gas.

[0049] In summary, when laminating the color box workpiece 7, it is transported by the first conveyor belt 2. When passing through the correction component 6, the position of the color box workpiece 7 is corrected, and at the same time, the outer surface of the color box workpiece 7 is cleaned. The glue coating component 8 is used to apply glue to 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 is passed through the pressure roller 5 and laminated on the upper surface of the color box workpiece 7. The pressure roller 5 has a certain pressure on the film, playing a role in leveling and expelling air bubbles. The exhaust component 9 is used to discharge the polluting gas generated during lamination, enabling the gas to be discharged and treated at a fixed point, achieving 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 block 69 to deviate. The deviation of the adjustment block 69 drives the correction frame 62 to deviate. The deviation of the correction frame 62 drives the slide rod 63 to slide in the inner cavity of the fixed frame 61. Under the elastic force of the first spring 65, the correction frame 62 returns to its original position. Even when subjected to external forces, the correction frame 62 will ultimately return to its far position, thereby driving the guide rod 611 to return to its original position, enabling the entire color box workpiece 7 to be transported in the middle part of the first conveyor belt 2. By rotating the first threaded rod 64, the adjustment block 69 is driven to slide on the correction frame 62, facilitating the adjustment of the distance between the adjustment blocks 69, making the color box workpiece 7 just pass through the distance between the parallel positions of the correction blocks 610. The first alarm mechanism 66 is used to issue an alarm when a deviation occurs, playing a detection role. The cleaning mechanism 68 is used to clean the outer surface of the color box workpiece 7, and the cleaning mechanism 68 adjusts the force on the color box workpiece 7 through the adjustment mechanism 67, enabling the cleaning mechanism 68 to have a flexible force during cleaning, facilitating the cleaning of the uneven texture on the outer surface of the color box workpiece 7. The glue coating amount is adjusted by adjusting the gap between the first glue coating roller 84 and the second glue coating roller 85. 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. By rotating the fourth threaded rod 83, 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 maintain a meshing device during the movement. When applying glue, the operation of the first motor 814 drives the second glue coating roller 85 to rotate. At the same time, the rotation of the rotating rod 88 drives the first glue coating roller 84 to rotate, making the rotation directions of the first glue coating roller 84 and the second glue coating roller 85 opposite, so that the glue flows from the gap between the first glue coating roller 84 and the second glue coating roller 85 onto 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 are kept parallel, preventing uneven coating caused by inconsistent gaps.
