Description

Technical Field

[0001] This utility model relates to the field of coloring machine technology, and in particular to a rapid drying device for a composite inner lining paper coloring machine. Background Technology

[0002] Composite liner paper coloring is a key process involving the uniform application of functional or decorative coatings to the surface of composite liner paper. It is widely used in packaging for tobacco, food, and pharmaceuticals to enhance the barrier properties, printability, and appearance quality of the liner paper. As a core step in packaging material production, the quality of the coloring and the efficiency of subsequent processing directly affect the performance and market competitiveness of the final product. Especially on high-speed continuous production lines, timely drying after coloring is crucial for ensuring coating curing, preventing adhesion, and improving production cycle time. However, existing coloring equipment often lacks an efficient and controllable drying system after coating, leading to insufficient drying or excessively long drying cycles, severely restricting overall production efficiency.

[0003] Utility model patent CN215164167U discloses a novel coloring device for producing environmentally friendly inner lining paper. It includes a circulating feeding mechanism, a coloring roller for coloring the inner lining paper, and an auxiliary pressure roller that cooperates with the coloring roller. The circulating feeding mechanism includes a recovery tray, a return pipe, a feeding box, a conveying pump, an output pipe, and a spray plate. The recovery tray is located below the coloring roller. One end of the return pipe is connected to the recovery tray, and the other end is connected to the feeding box. The suction inlet of the conveying pump is connected to the feeding box, and the output outlet of the conveying pump is connected to one end of the output pipe. The other end of the output pipe is connected to the spray plate. The spray plate and the auxiliary pressure roller are respectively located on both sides of the coloring roller. This utility model achieves the recycling and reuse of residual paint through the circulating feeding mechanism, effectively avoiding pollution caused by the long-term exposure of residual paint to the outside environment and its volatilization into the air, making it green and environmentally friendly. Specifically, existing coloring equipment generally uses natural air drying or simple hot air ovens for drying, which suffers from prominent problems such as slow drying speed, uneven heat distribution, high energy consumption, and large space occupation. Due to the lack of a rapid drying module tightly integrated with the coloring machine, the wet film coating is easily contaminated by external dust during transport and is prone to scratches or adhesion before complete curing, seriously affecting the surface quality of the product. The paper liner coloring machine uses a rapid drying device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid drying device for a composite inner lining paper coloring machine, which solves the problems in the prior art of lacking a rapid drying module that is closely integrated with the coloring machine, the wet film coating being easily contaminated by external dust during the transmission process, and being prone to scratches or adhesion before complete curing, which seriously affects the surface quality of the product.

[0005] To achieve the above objectives, this utility model provides a rapid drying device for a composite inner lining paper coloring machine, including a base, a coloring machine fixedly connected to one side of the top of the base, and a side frame fixedly connected to the other side of the top of the base. A drive motor is bolted to one side of the outer wall of the side frame, and a winding rod is rotatably connected to the inner side of the side frame. One end of the winding rod passes through the side wall of the side frame and is connected to the output shaft of the drive motor. A side plate is fixedly connected to the top of the base. Cleaning rods are rotatably connected to the upper and lower sides of the side plate. One end of each cleaning rod passes through the side plate and is engaged with the other end. One end of one of the cleaning rods is connected to the end of the winding rod by a belt. A first air hood is fixedly connected to the upper side of the side frame, and a second air hood is fixedly connected to the upper other side of the side frame. A hot air blower is bolted to the top of the side frame, and the tops of both the first and second air hoods are connected to the outlet of the hot air blower.

[0006] The upper and lower sides of the side plate are both fixedly connected to scrapers.

[0007] One end of the winding rod is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the winding rod passes through the side wall of the side frame via a bearing sleeve. One end of each of the two cleaning rods passes through the side plate via a bearing sleeve.

[0008] Each of the two cleaning rods has a gear fitted onto one end, and the two gears are meshed together.

[0009] One of the two cleaning rods and one of the winding rods are fitted with pulleys, and the two pulleys are connected by a belt winding.

[0010] A fixing plate is fixedly connected to the top side of the side frame, and the top of the first air outlet hood is fixedly connected to the bottom of the fixing plate.

[0011] This invention discloses a rapid drying device for a composite liner paper coloring machine. By installing a first and second air outlet hood on the side frame and connecting them to a hot air blower, it provides a centralized and controllable hot air drying environment along the transport path of the composite liner paper after coloring. This effectively solves the problems of slow drying speed and uneven heat distribution caused by relying on natural air drying or independent ovens in the prior art, significantly shortening the drying cycle and improving overall production efficiency. The integrated design of the hot air blower and the air outlet hood allows the drying module to work closely with the coloring machine and winding structure, avoiding the defects of large space occupation and poor process connection caused by the dispersed drying area in traditional equipment, thus improving the space utilization and operational continuity of the equipment. At the same time, two interlocking cleaning rods are installed on the side plate and linked to the winding rod by a belt, which can simultaneously clean the coating surface during the movement of the composite liner paper. The removal of excess paint prevents defects such as sagging and blistering caused by paint accumulation. This structure not only compensates for the lack of online cleaning function in existing coloring equipment, but also achieves synchronous coordination between cleaning and winding actions through mechanical linkage, eliminating the need for an additional power source and reducing energy consumption and control complexity. More importantly, the synergistic effect of cleaning and rapid hot air drying reduces the exposure time of the wet film, lowering the risk of dust pollution and surface scratches, thereby improving the stability and consistency of product surface quality, reducing solvent residue problems caused by insufficient drying, and enhancing the environmental safety of the product. The overall structure is rationally laid out, with each functional module integrated on the base for easy installation and maintenance. It is suitable for processing composite inner lining paper of different widths and materials, meeting the requirements of modern high-speed, high-precision, and continuous production for efficient, stable, and energy-saving post-coloring processing.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1-5 A rapid drying device for a composite inner lining paper coloring machine includes a base 1, a coloring machine 2 fixedly connected to one side of the top of the base 1, and a side frame 3 fixedly connected to the other side of the top of the base 1. A drive motor 5 is fixedly connected to one side of the outer wall of the side frame 3 by bolts, and a winding rod 4 is rotatably connected to the inner side of the side frame 3. One end of the winding rod 4 passes through the side wall of the side frame 3 and is connected to the output shaft of the drive motor 5. A side plate 6 is fixedly connected to one side of the top of the base 1, and cleaning rods are rotatably connected to both the upper and lower sides of the side plate 6. 7. One end of each of the two cleaning rods 7 passes through the side plate 6, and the two cleaning rods 7 are meshed together. One end of one of the two cleaning rods 7 is connected to one end of the winding rod 4 by a belt 15. A first air hood 10 is fixedly connected to one side of the upper part of the side frame 3, and a second air hood 12 is fixedly connected to the other side of the upper part of the side frame 3. A hot air blower 11 is fixedly connected to one side of the top of the side frame 3 by bolts. The top of the first air hood 10 and the top of the second air hood 12 are both connected to the outlet of the hot air blower 11.

[0021] First, the composite liner paper to be processed is fed into the inlet of the coloring machine 2. The coloring roller and auxiliary pressure roller inside the coloring machine 2 work together to evenly coat the surface of the composite liner paper with coating. After coating, the composite liner paper is led out from the outlet of the coloring machine 2 and passes through the gap between two cleaning rods 7 rotatably connected between the upper and lower parts of the side plate 6 located on the top side of the base 1. At this time, the drive motor 5 starts, and its output shaft drives the winding rod 4 inside the side frame 3 to rotate through a transmission connection. Simultaneously, one end of the winding rod 4 transmits power to one of the cleaning rods 7 via a belt 15. This cleaning rod 7 then transmits the rotational motion to the other cleaning rod 7 through a meshing connection, causing the two cleaning rods 7 to rotate synchronously in opposite directions. This lightly scrapes and smooths the surface of the composite liner paper during its movement, removing the coating. Excess paint residue after coloring is removed and coating buildup is prevented. During this process, the composite inner liner paper is continuously conveyed forward and eventually wound onto the winding rod 4. As the winding rod 4 rotates continuously, the colored composite inner liner paper is wound up. At the same time, the hot air blower 11 is started, and the generated hot air is delivered to the first air hood 10 and the second air hood 12 through the top outlet. These two air hoods are located on the upper sides of the side frame 3, which can blow hot air evenly onto the surface of the moving composite inner liner paper. Especially in the key areas after coloring, before cleaning, or after cleaning and before winding, effective hot air coverage is formed, thereby quickly and continuously drying the wet film coating with hot air, ensuring that the coating reaches a preliminary curing state before winding, avoiding adhesion and scratches. The whole process realizes the integrated continuous operation of coloring, cleaning, drying and winding.

[0022] Furthermore, scrapers 8 are fixedly connected to both the upper and lower sides of the side plate 6. When the composite inner liner paper passes through the gap between the two cleaning rods 7, the scraper 8 can perform additional physical cleaning on the surface of the composite inner liner paper, removing any larger particles or impurities that may remain, and preventing them from affecting the quality of subsequent coatings. This design effectively improves the cleanliness of the post-coating process and the quality of the final product.

[0023] Furthermore, one end of the winding rod 4 is rotatably connected to the inner wall of the side frame 3 via a rotating shaft, and the other end of the winding rod 4 passes through the side wall of the side frame 3 through a bearing sleeve. One end of each of the two cleaning rods 7 passes through the side plate 6 through a bearing sleeve, ensuring that the winding rod 4 and the cleaning rod 7 can rotate smoothly and with low friction under the drive of the drive motor 5, reducing mechanical wear, extending the service life of the equipment, and ensuring transmission efficiency, so that the composite inner lining paper can be evenly wound up, and the cleaning process is smoother.

[0024] Furthermore, a gear 13 is fitted onto one end of each of the two cleaning rods 7, and the two gears 13 mesh with each other, achieving the effect of the two cleaning rods 7 rotating synchronously in opposite directions. This can more effectively clean the surface of the composite inner lining paper, not only removing excess coating, but also avoiding unevenness caused by coating accumulation on the paper surface, thereby improving the overall quality and aesthetics of the coating.

[0025] Furthermore, pulleys 14 are fitted onto one end of one of the two cleaning rods 7 and one end of the winding rod 4, and the two pulleys 14 are connected by a belt 15. The cleaning rod 7 and the winding rod 4 can be driven simultaneously using a single drive source, which simplifies the design of the power transmission system, reduces costs, and also reduces energy loss during equipment operation, thereby improving energy efficiency.

[0026] Furthermore, a fixing plate 9 is fixedly connected to the top side of the side frame 3, and the top of the first air outlet hood 10 is fixedly connected to the bottom of the fixing plate 9, which enhances the installation stability and positional accuracy of the first air outlet hood 10, ensuring that the hot air generated by the hot air blower 11 can accurately cover the surface of the composite inner lining paper that needs to be dried, providing stable drying conditions, further ensuring the rapid curing of the coating, and reducing product quality problems caused by insufficient drying.

[0027] In summary: First, the composite liner paper to be processed is fed into the inlet end of the coloring machine 2. The coloring roller and auxiliary pressure roller inside the coloring machine 2 work together to evenly coat the surface of the composite liner paper with coating. After the coating is completed, the composite liner paper is led out from the outlet end of the coloring machine 2 and passes through the gap between two cleaning rods 7 that are rotatably connected between the upper and lower parts of the side plate 6 located on the top side of the base 1. During this process, scrapers 8 are fixedly connected to both the upper and lower sides of the side plate 6. When the composite liner paper passes through the gap between the two cleaning rods 7, the scrapers 8 can perform additional physical cleaning on the surface of the composite liner paper to remove any larger particles or impurities that may remain, preventing them from affecting the quality of subsequent coatings. At this time, the drive motor 5 starts, and its output shaft drives the winding rod 4 inside the side frame 3 to rotate through the transmission connection. One end of the winding rod 4 is rotatably connected to the inner wall of the side frame 3 through a rotating shaft, and the other end of the winding rod 4 passes through the side wall of the side frame 3 through a bearing sleeve. This ensures that the winding rod 4 can rotate smoothly and with low friction under the drive of the drive motor 5, reducing mechanical wear, extending the service life of the equipment, and ensuring transmission efficiency. At the same time, one end of the winding rod 4 transmits power to one of the cleaning rods 7 through the belt 15. The cleaning rod 7 then transmits the rotational motion to the other cleaning rod 7 through the gear 13 that meshes between the two, so that the two cleaning rods 7 rotate synchronously in opposite directions. This allows the composite inner lining paper to be slightly scraped and smoothed during its movement, removing excess paint residue after coloring and preventing coating accumulation, thereby improving the overall quality and aesthetics of the coating. During this process, the composite inner liner paper is continuously conveyed forward and eventually wound onto the winding rod 4. As the winding rod 4 rotates continuously, the coated composite inner liner paper is wound up. Simultaneously, the hot air blower 11 is started, and the generated hot air is delivered through the top outlet to the first air outlet hood 10 and the second air outlet hood 12. These two air outlet hoods are located on the upper sides of the side frame 3, respectively. A fixing plate 9 is fixedly connected to the top side of the side frame 3, and the top of the first air outlet hood 10 is fixedly connected to the bottom of the fixing plate 9, which enhances the installation stability and positional accuracy of the first air outlet hood 10. This ensures that the hot air generated by the hot air blower 11 can accurately cover the surface of the composite inner liner paper that needs to be dried, providing stable drying conditions and further ensuring the rapid curing of the coating. By setting up the scraper 8, the cleanliness of the post-coating process is effectively improved, avoiding the influence of impurities on the coating quality, thereby improving the quality of the final product. By employing a combination of a rotating shaft and a bearing sleeve to ensure the rotational connection of the winding rod 4 and the cleaning rod 7, mechanical wear is reduced, and the long service life and high-efficiency operation of the equipment are guaranteed. This achieves uniform winding of the composite inner lining paper and smooth cleaning process. The gear 13 enables the two cleaning rods 7 to rotate synchronously in opposite directions, effectively removing excess coating, preventing unevenness caused by coating accumulation, and improving the quality and aesthetics of the coating.Furthermore, the design of pulley 14 and belt 15 simplifies the power transmission system, reduces costs, minimizes energy loss, and improves energy efficiency. Finally, the application of fixing plate 9 enhances the stability of the first air outlet hood 10, ensuring that the hot air generated by the hot air blower 11 accurately acts on the surface of the composite inner liner paper, providing consistent drying conditions and significantly reducing product quality issues caused by insufficient drying, thus meeting the needs of efficient and high-quality production. The entire design achieves integrated continuous operation of coloring, cleaning, drying, and winding, significantly improving production efficiency and product quality.
