[0038] Reference Figure 4 - Figure 6The top of the curing box 1 is fixedly connected with a heating box 5. The heating box 5 provides additional heat for the curing of paper products. The heating box 5 is connected with a plurality of air inlet fans 24 on the left and right sides. The air inlet fan 24 is usually composed of a motor, a fan blade and a shell. The motor provides power for the rotation of the fan blade. The function of the air inlet fan 24 is to extract external air and deliver it to the inside of the heating box 5 to form air circulation and provide air source for heating and subsequent curing process. The air inlet fan 24 is arranged in an array. The left and right sides of the heating box 5 are fixedly connected with isolation nets 20 made of stainless steel wire mesh. The isolation net 20 can effectively block the entry of external large particles into the heating box 5 to protect the internal parts from damage. The isolation net 20 and the air inlet fan 24 are provided with filter plates 23. The filter plate 23 is made of a combination of fiber filter material and metal frame. The fiber filter material can effectively filter the small dust and impurities in the air, and the metal frame provides structural support to ensure the stability and durability of the filter plate 23. The filter plate 23 is used to finely filter the air entering the heating box 5 to further purify the air and prevent impurities from affecting the curing quality of the paper product. The filter plate 23 is slidingly connected inside the heating box 5. The top of the filter plate 23 is provided with a dust cover 21 made of engineering plastic. The dust cover 21 prevents dust and other impurities from entering the heating box 5 from the top of the filter plate 23 and protects the filter plate 23 during equipment operation. The dust cover 21 is slidingly connected to the top of the heating box 5. The top of the dust cover 21 and the heating box 5 are fixedly connected with a hinge 22. The hinge 22 connects the dust cover 21 and the heating box 5 to allow the dust cover 21 to rotate around the hinge 22. The left and right sides and the upper and lower sides of the isolation net 20 are fixedly connected with fixed blocks 28. The inside of the fixed block 28 is slidingly connected with a connecting column 27. The function of the connecting column 27 is to convert the rotation of the movable handle 29 into the linear displacement of the locking column 26 to realize the locking and unlocking operation of the filter plate 23. The bottom of the connecting column 27 is fixedly connected with a locking column 26. The top of the connecting column 27 is rotatably connected with a movable handle 29. The outer wall of the connecting column 27 is sleeved with a limiting spring 25. One end of the limiting spring 25 is fixedly connected to the inner wall of the fixed block 28. The other end of the limiting spring 25 is fixedly connected to the side wall of the locking column 26.

[0039] Specifically, the plurality of air inlet fans 24 inside the heating box 5 start to work. After the motor inside the air inlet fan 24 is powered on, it drives the fan blade to rotate at high speed. The rotation of the fan blade generates negative pressure, thereby extracting air from the outside. The air first passes through the isolation net 20, and the stainless steel wire mesh of the isolation net 20 blocks larger impurities. Then the air enters the filter plate 23 inside. The fiber filter material of the filter plate 23 filters the tiny dust and impurities in the air through physical interception. The filtered air is input into the heating box 5 for heating. During daily equipment maintenance, the worker holds the movable handle 29, takes the rotating connection point between the movable handle 29 and the connecting column 27 as the axis, and rotates the movable handle 29 upward. The rotation of the movable handle 29 drives the connecting column 27 connected inside to displace outward along the vertical direction in the fixed block 28. At the same time, the displacement of the connecting column 27 drives the bottom fixedly connected locking column 26 to displace outward. The locking column 26 is separated from the hole in the filter plate 23 along the same direction as the connecting column 27. In the process of outward displacement of the locking column 26, the limiting spring 25 sleeved on the outer wall of the connecting column 27 is subjected to the outward pulling force of the connecting column 27, and is displaced outward and compressed under the action. The spring steel wire inside the limiting spring 25 is elastically deformed, and stores elastic potential energy. At this time, the worker manually opens the dustproof cover 21. The worker holds the slot at the top of the dustproof cover 21, takes the hinge 22 as the axis, and rotates the dustproof cover 21 upward, so that it is opened from the top of the heating box 5. Then the worker holds the handle at the top of the filter plate 23 and pulls it upward, and takes the filter plate 23 out of the heating box 5 along the vertical direction, and cleans or replaces it, thereby completing the quick replacement of the filter plate 23, and achieving the effect of efficiently and quickly maintaining the equipment.

[0040] Working principle: when using the curing mechanism of the paper product environment-friendly printing process, the printed paper product enters the curing box 1 with the conveying table 2, then the lifting door 6 is closed, at this time the multiple air inlet fans 24 in the heating box 5 start to work and extract the air outside, the air enters the filter plate 23 through the isolation net 20, after being filtered by the filter plate 23, the air is input into the heating box 5 for heating, then the air supply device 7 on the left and right sides of the curing box 1 starts to convey hot air to the inside of the curing box 1, at the same time, the multiple driving motors 9 at the top start to work, the output shaft 11 drives the rotating arm 12 and the connecting rod 13 to rotate, the rotation of the connecting rod 13 promotes the sliding block 14 to slide on the outer wall of the slide rod 18, the sliding of the sliding block 14 drives the swing arm 17 at both ends of the slide rod 18 to swing around the fixed rod 16 at the bottom as the axis, the swing of the fixed rod 16 promotes the connecting plate 19 at the bottom to swing synchronously, at the same time, it also drives the curing lamp 8 to swing, so as to light cure the paper product above the conveying table 2, so as to achieve the effect of uniform irradiation and overall light curing of the paper product. When maintaining the equipment, the staff bends the movable handle 29 on the left and right sides of the isolation net 20 upwards, the rotation of the movable handle 29 drives the locking column 26 connected inside to displace outward, the displacement of the locking column 26 drives the limiting spring 25 to displace outward at the same time, which is out of the hole in the filter plate 23, and makes the air inlet fan 24 compress, at this time the staff manually opens the dust cover 21, and takes out the filter plate 23 through the handle at the top of the filter plate 23 for cleaning or replacement, so as to complete the quick replacement of the filter plate 23, so as to achieve the effect of efficient and rapid maintenance of the equipment.
