Technical Field

[0001] This utility model relates to the field of packaging paper production technology, specifically to a packaging paper drying device. Background Technology

[0002] In the production of packaging paper, the drying process is a core step affecting the physical properties and surface quality of the paper. With the increasing market demand for diversified packaging materials, manufacturers face two major challenges:

[0003] I. Compatibility requirements for multiple types of paper: The thickness of packaging paper varies significantly in different application scenarios, such as food packaging paper and industrial paper. Traditional drying equipment, due to its fixed pressure or single-sided heating design, cannot balance the protection of thin paper from breakage and the thorough drying of thick paper, resulting in low equipment utilization.

[0004] Second, traditional drying equipment usually relies on extending the heating time or increasing the temperature to ensure the drying effect, but this easily leads to energy waste and lacks cooling treatment for the dried paper, resulting in quality problems such as curling and sticking of the finished product.

[0005] To address the aforementioned issues, we propose a drying device for packaging paper production. Utility Model Content

[0018] Example 1

[0019] like Figures 1 to 4As shown, this utility model discloses a drying device for packaging paper production. The technical solution includes a workbench 1, a support frame 2 at the bottom of the workbench 1, and material racks 14 symmetrically welded to the left middle of the support frame 2. Material rollers 15 are detachably installed on the material racks 14. First feed rollers 9 are rotatably installed in the grooves at the left and right ends of the workbench 1. A lower electric heating roller 6 is rotatably installed in the rectangular groove 4 in the middle of the workbench 1. An upper electric heating roller 7 is located directly above the lower electric heating roller 6. The device also includes a temperature controller 13. The device 13 is located in the middle of the front side of the workbench 1. The temperature controller 13 is electrically connected to the lower heating roller 6 and the upper heating roller 7. The lower heating roller 6 and the upper heating roller 7 are maintained at a constant high temperature by the temperature controller 13, and the heat is transferred to both sides of the paper to accelerate the evaporation of paper moisture. The front and rear ends of the upper heating roller 7 are respectively fixedly connected to the pressing unit 5 set on the top of the workbench 1. The pressing unit 5 includes a pressing seat 51, a guide rod 52, an electric telescopic rod 53, a compression spring 54, a connecting plate 55, a T-shaped guide hole 56, and a stop block 57. There are two electric telescopic rods 53. Electric telescopic rods 53 are symmetrically arranged at the front and rear of the upper surface of the workbench 1. Connecting plates 55 are fixedly installed at the top of the telescopic ends of the electric telescopic rods 53. Pressure seats 51 are respectively arranged below the connecting plates 55. The middle of the pressure seats 51 is rotatably connected to the front and rear ends of the upper electric heating roller 7. T-shaped guide holes 56 at the left and right ends of the pressure seats 51 are slidably connected to guide rods 52 at the bottom of the connecting plates 55. Stop blocks 57 are fixedly installed at the bottom of the guide rods 52. Compression springs 54 are arranged above the pressure seats 51, and the compression springs 54 are respectively fitted with... The guide rod 52 is placed on the outside. By activating the electric telescopic rod 53, the connecting plate 55 is driven to move the pressure seat 51 downward, so that the upper electric heating roller 7 is close to the lower electric heating roller 6. It also includes a guide rod frame 8. There are two guide rod frames 8, and the guide rod frames 8 are in an inverted "U" shape. The guide rod frames 8 are slidably installed in the sliding holes set at the left and right ends of the connecting plate 55. The bottom of the guide rod frame 8 is fixedly connected to the upper surface of the worktable 1. The compression spring 54 is compressed on the outside of the guide rod 52. The elastic force makes the upper electric heating roller 7 adhere to the surface of the packaging paper with adaptive pressure to avoid over-pressure or under-pressure.The guide rod frame 8 ensures the stable vertical lifting and lowering of the pressure seat 51, preventing deviation. It also includes a second feed roller 10, which is rotatably mounted on the right side of the support frame 2. A connecting frame 11 is located at the top right side of the support frame 2. Several cooling fans 12 are evenly arranged in the middle of the connecting frame 11. After being guided by the first feed roller 9 at the right end of the worktable 1, the dried paper passes around the bottom left end of the second feed roller 10 on the right side of the support frame 2, forming an "S" shaped path. When the dried paper passes through the left end of the connecting frame 11, the cooling fans 12 are activated by the controller 3. The generated airflow rapidly cools the paper, preventing residual heat from causing deformation or sticking, and simultaneously solidifying the drying effect. The controller 3 is located at the front right end of the worktable 1 and is electrically connected to the electric telescopic rod 53, the cooling fans 12, the temperature controller 13, and an external power supply.

[0020] The working principle of this utility model is as follows: First, the packaging paper roll to be dried is placed on the material roller 15 of the material rack 14. The end of the paper passes over the first material roller 9 at the left end of the workbench 1 and the lower electric heating roller 6 in the rectangular groove 4. At this time, the lower electric heating roller 6 is preheated to the set temperature by the temperature controller 13 to prepare for drying. Then, the electric telescopic rod 53 is activated by the controller 3, which drives the connecting plate 55 to move the pressing seat 51 down, so that the upper electric heating roller 7 is close to the lower electric heating roller 6. The compression spring 54 is compressed on the outside of the guide rod 52. Through the elastic force, the upper electric heating roller 7 is pressed against the surface of the packaging paper with adaptive pressure to avoid over-pressure or under-pressure. The guiding function of the guide rod frame 8 ensures the pressing of the paper. The seat 51 is raised and lowered vertically to prevent deviation. Secondly, the packaging paper is clamped between the lower heating roller 6 and the upper heating roller 7. The lower heating roller 6 and the upper heating roller 7 are kept at a constant high temperature by the temperature controller 13. The heat is transferred to both sides of the paper to accelerate the evaporation of paper moisture. After being guided by the first feed roller 9 on the right end of the worktable 1, the dried paper passes around the bottom left end of the second feed roller 10 on the right side of the support frame 2, forming an "S" shaped path, and is pulled by the external paper winding device. When the dried paper passes through the left end of the connecting frame 11, the cooling fan 12 is activated by the controller 3. The generated airflow cools the paper quickly to prevent residual heat from causing deformation or sticking, and at the same time solidifies the drying effect.
