Description

Technical Field

[0001] The utility model relates to the technical field of cardboard drying, and more particularly to a high-speed and silent cardboard drying device. Background Art

[0002] The high-speed, silent cardboard drying device is used during the cardboard production process, particularly to dry cardboard after coating and printing. This device utilizes high-speed, silent drying technology to effectively improve production efficiency and drying quality, and is widely used in the manufacturing of cardboard products such as cartons, boxes, and packaging paper.

[0003] In existing technologies, firstly, the drying systems of some devices can only rely on a single heat source and airflow, which will lead to uneven drying of the surface and interior of the cardboard, which may significantly extend the drying time and reduce production efficiency. The multi-layer structure allows hot air to be transferred between the multiple layers of cardboard to achieve uniform drying. Without this function, some areas may overheat during the drying process while other areas remain moist, affecting the quality of the cardboard. Secondly, some devices cannot flexibly adjust the intensity of the hot air, resulting in insufficient drying or over-drying of the cardboard in some areas, affecting the quality of the final product. It may also cause the drying system to have poor adaptability to different types of cardboard, unstable working conditions, and prone to equipment failure or performance degradation.

[0031] In this embodiment, the multi-layer drying mechanism primarily uses hot air to efficiently dry the cardboard. The hot blower 2 heats and generates hot air, which enters the drying tube 4 through the diverter pipe 3 and is blown toward the bottom of the placement plate 6 through the drying holes 5. The cardboard on the placement plate 6 absorbs the heat from the hot air, rapidly evaporating moisture from its surface, thereby achieving a drying effect. Multiple groups of placement plates 6 operate in parallel, ensuring that the cardboard is evenly dried by the hot air. The drying adjustment mechanism adjusts the opening and closing of different drying holes 5, thereby controlling the flow and distribution of hot air and, in turn, adjusting the drying effect of the cardboard. The adjustment plate 8 adjusts the opening size of the drying holes 5 and controls the distribution of hot air by sliding on the back longitudinal plate 7. The clamping rod 10 cooperates with different clamping tubes 9 to achieve lateral position adjustment of the adjustment plate 8, precisely controlling the opening and closing of each drying hole 5. The directional screw 13 and threaded sleeve 12 cooperate to control the fixed position of the clamping rod 10, making the movement of the adjustment plate 8 more precise, preventing heat waste and ensuring that the flow rate and temperature of each drying hole 5 reach the desired values.

[0032] The adjustment auxiliary mechanism includes an adjusting tube 14, an insertion hole 15, a spring push rod 16, a sliding sleeve 17, a rotating tooth 18 and a tooth plate 19.

[0033] In this embodiment, the adjustment auxiliary mechanism is mainly used to assist in adjusting the opening and closing of the drying hole 5, providing a finer adjustment function to ensure a more accurate drying process. The user slides the adjustment sleeve on the outer wall of the clamping tube 9, and the sliding sleeve 17 moves longitudinally under the guidance of the adjustment tube 14, driving the tooth plate 19 to move, and the tooth plate 19 drives the rotating teeth 18 to rotate, driving the threaded sleeve 12 to rotate, and driving the movement of the directional screw 13. The directional screw 13 adjusts the position of the clamping rod 10, and finally accurately controls the lateral position of the adjustment plate 8.

[0035] More specifically, the hot blower 2 generates hot air, which enters the drying pipe 4 through the diversion pipe 3 and is sent to the drying hole 5 under the placement plate 6. The hot air is blown evenly onto the cardboard through the drying hole 5, and the moisture on the surface of the cardboard evaporates rapidly, completing the drying. The user adjusts the opening and closing of the drying hole 5 by adjusting the drying adjustment mechanism as needed, and accurately controls the hot air flow of each drying hole 5.

[0036] In summary, when the overall equipment is in use or running: when the operation of the multi-layer drying mechanism is required, the main function of the multi-layer drying mechanism is to efficiently dry the cardboard through hot air. The hot blower 2 heats and generates hot air. The hot air enters the drying pipe 4 through the diversion pipe 3 and is blown to the bottom of the placement plate 6 through the drying hole 5. The cardboard on the placement plate 6 absorbs the heat in the hot air, and the moisture on the surface of the cardboard evaporates quickly, thereby achieving a drying effect. Multiple groups of placement plates 6 work in parallel to ensure that the cardboard can be evenly dried under the action of hot air.

[0037] When the drying adjustment mechanism needs to be operated, the function of the drying adjustment mechanism is to adjust the opening and closing of different drying holes 5 respectively, thereby controlling the flow and distribution of hot air, and then adjusting the drying effect of the cardboard. The adjustment plate 8 adjusts the opening size of the drying hole 5 and controls the distribution of hot air by sliding on the back longitudinal plate 7. The clamping rod 10 cooperates with different clamping tubes 9 to realize the lateral position adjustment of the adjustment plate 8 and accurately control the opening and closing of each drying hole 5. The cooperation of the directional screw 13 and the threaded sleeve 12 controls the fixed position of the clamping rod 10, making the movement of the adjustment plate 8 more precise, which not only prevents heat waste, but also ensures that the flow and temperature of each drying hole 5 reach the required values.

[0038] When the operation of the auxiliary mechanism needs to be adjusted, the auxiliary mechanism is mainly used to assist in adjusting the opening and closing of the drying hole 5, providing a finer adjustment function to ensure that the drying process is more accurate. The user slides the adjustment sleeve on the outer wall of the clamping tube 9, and the sliding sleeve 17 moves longitudinally under the guidance of the adjustment tube 14, driving the tooth plate 19 to move, and the tooth plate 19 drives the rotating teeth 18 to rotate, driving the threaded sleeve 12 to rotate, and driving the movement of the directional screw 13. The directional screw 13 adjusts the position of the clamping rod 10, and finally accurately controls the lateral position of the adjustment plate 8.

[0039] The hot air blower 2 generates hot air, which enters the drying pipe 4 through the diversion pipe 3 and is sent to the drying holes 5 under the placement plate 6. The hot air is blown evenly onto the cardboard through the drying holes 5, and the moisture on the cardboard surface evaporates quickly, completing the drying. The user can adjust the opening and closing of the drying holes 5 by adjusting the drying adjustment mechanism as needed, and accurately control the hot air flow of each drying hole 5. The adjustment auxiliary mechanism provides more detailed adjustment capabilities. Through the coordinated action of the tooth plate 19 and the rotating teeth 18, the precise control of the adjustment hole is achieved. The automation and precise adjustment function of the entire system ensure the stability of the drying process, and the drying intensity and time can be adjusted as needed to ensure that the cardboard is dried evenly and quickly, avoiding excessive or insufficient drying.
