Description

Technical Field

[0001] This utility model relates to the field of water-based ink printing machine technology, and in particular to an ink drying mechanism for a water-based ink printing machine. Background Technology

[0002] A water-based ink printer is a device that uses water-based inks for printing. Water-based inks contain a certain amount of water and dry relatively slowly under natural conditions. If drying is not performed, the freshly printed patterns or text may bleed and become blurry due to the ink not being dry. Therefore, drying is necessary after printing.

[0003] For example, Chinese patent CN220535231U discloses a water ink drying device for a gravure printing machine, which includes a drying box and a conveying mechanism. The drying box has inlet and outlet ports at both ends, and the conveying mechanism is installed inside the drying box. It also includes a drying mechanism, an air outlet mechanism, and an adsorption mechanism. The drying mechanism is installed at the bottom of the drying box, and the output end of the drying mechanism is located inside the drying box. The air outlet mechanism is installed at the top of the drying box, and the input end of the air outlet mechanism is connected to the inside of the drying box. The adsorption mechanism is connected to the output end of the air outlet mechanism.

[0004] In the aforementioned patent, although the problem of low drying efficiency is solved by drying, the heated gas is transported through a three-way pipe and a second branch pipe, which involves a long transport distance. During the transport process, some of the heat of the air will be continuously lost, causing the temperature of the hot air to drop, thereby affecting the drying effect on the paper. Utility Model Content

A connector 21 is slidably connected to one side of the protective cover 1. A connecting frame 16 is fixedly connected to one end of the connector 21. The inner wall of the connecting frame 16 is fixedly connected to the heating tube 17. The heating tube 17 consists of two sets arranged symmetrically at the top and bottom. A rack 20 is fixedly connected to one side of the connector 21. A gear 19 meshes with one side of the rack 20. One side of the gear 19 meshes with another rack 20. One side of the gear 19 is rotatably connected to the guide plate 15.

[0024] One of the racks 20 is fixedly connected to a hydraulic push rod 14 on one side, and the hydraulic push rod 14 is fixedly connected to the frame 4 on one side. A guide rail 18 is slidably connected to one side of the rack 20, and the guide rail 18 is fixedly connected to a guide plate 15 on one side. The guide plate 15 is fixedly connected to a fixing strip 2 on one side. A preheating roller 13 is provided at the bottom of the preheating cover 12, and one end of the preheating roller 13 is rotatably connected to the conveying assembly 3.

[0025] The frame 4 assists in the installation and connection of one side of the entire mechanism with the printing press. The frame 4 supports the bottom of the conveying assembly 3, and the fixing strip 2 supports the bottom of the protective cover 1. The blower 7 accelerates the airflow inside the protective cover 1, and the protective cover 1 supports one side of the exhaust fan 11. The exhaust fan 11 extracts the hot air from inside the protective cover 1, and the pipe guides the airflow. The preheating cover 12 assists in the exhaust of hot air. The preheating cover 12 and the preheating roller 13 with heating wires installed inside can achieve the preheating treatment of the paper. The guide plate 15 supports the installation of the guide rail 18, and the guide rail 18 guides the lifting and lowering of the rack 20, thereby improving the stability of the rack 20 during lifting and lowering. The hydraulic push rod 14 provides power for the lifting and lowering of one rack 20, and the gear 19 assists in the lifting and lowering of the other rack 20, thereby adjusting the distance between the two sets of heating tubes 17. The heating tubes 17 heat the inside of the protective cover 1, accelerating the drying of the printed pattern on the paper surface.

[0026] Example 2: Figure 1 and Figure 2 As shown, a control box is fixedly connected to one side of the protective cover 1. The control box is electrically connected to a hydraulic push rod 6. The outer ring of the hydraulic push rod 6 is fixedly connected to the protective cover 1. A mounting bracket 22 is fixedly connected to the bottom of the hydraulic push rod 6. A leveling roller 5 is rotatably connected to one side of the mounting bracket 22. A limiter 10 is inserted into one side of the mounting bracket 22. An auxiliary plate 8 is inserted into one end of the limiter 10. One side of the auxiliary plate 8 overlaps with the mounting bracket 22. A leveling roller 9 is provided at the bottom of the leveling roller 5. One end of the leveling roller 9 is rotatably connected to the conveying assembly 3.

[0027] The control box can control the operation of the hydraulic push rod 16 and the opening and closing of the heating tube 17. The hydraulic push rod 16 can adjust the height of the mounting frame 22, thereby changing the distance between the leveling roller 15 and the leveling roller 29. The limiting member 10 can limit and fix the auxiliary plate 8 on one side of the mounting frame 22. The leveling roller 15 and the leveling roller 29 can assist in the leveling of the paper, reduce paper deformation, and ensure the quality of subsequent paper processing.

[0028] The usage and working principle of this device are as follows: The entire mechanism is installed on the printing press, located on one side of the printing area. The printed paper is conveyed through the conveyor structure to the drying mechanism for drying. First, the conveyor assembly 3 has a drive structure installed inside, which can drive the conveyor wheel to rotate and convey the paper. The exhaust fan 11 can send the hot air inside the protective cover 1 into the preheating cover 12 through the pipe and exhaust it. When the printed paper moves between the preheating cover 12 and the preheating roller 13, the bottom of the paper contacts the preheating roller 13 and the top contacts the hot air exhausted from the preheating cover 12 to achieve preheating. After preheating, it enters the protective cover 1. The blower 7 accelerates the air flow inside the protective cover 1. Two sets of symmetrically arranged heating tubes 17 heat the paper to make the paper dry quickly. After drying, the paper is removed from the protective cover 1 and then the top and bottom sides contact the leveling roller 5 and the leveling roller 9 respectively for leveling.

[0029] When the paper is thin, the hydraulic push rod 14 drives one of the racks 20 to move downward. When the rack 20 moves, it drives the gear 19 to rotate. Through the meshing of the gear 19 with the other rack 20, the other rack 20 is driven to move upward along the guide rail 18, thereby increasing the distance between the two sets of heating tubes 17 and avoiding damage to the paper from high temperature.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
