[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, a drying device for corrugated box production includes a base 1 and a drying chamber 12 arranged on the base 1;

[0027] like Figure 2 and Figure 3 As shown, when implemented, it includes: a support frame 11, which is arranged in a drying chamber 12, and grooves 101 are provided on both sides of the support frame 11, and the grooves 101 are used for limiting the sliding of the support frame 11. A paper placement screen frame 2 is provided on the surface of the support frame 11, and both sides of the paper placement screen frame 2 are slidably arranged in the grooves 101. Two sets of driving guide wheels 32 are provided on the outside of the drying chamber 12, and the two sets of driving guide wheels 32 are respectively in contact with the outer wall surface of the paper placement screen frame 2 for conveying the paper placement screen frame 2;

[0028] Specifically, as a preferred embodiment, base plates 3 are connected to both sides of the exterior of the drying chamber 12. Each base plate 3 is rotatably provided with a set of pulleys 31. Each set of drive guide wheels 32 is connected to a corresponding set of pulleys 31. Each set of pulleys 31 is connected via a belt. A DC servo motor is connected to each base plate 3, and the main shaft of the DC servo motor is connected to the pulleys 31. Before implementation, a tensioner is installed on the base plate 3 to tension each set of belts. By synchronously starting the two DC servo motors, the two sets of pulleys 31 and the drive guide wheels 32 rotate, thereby guiding the paper placement frame 2 to be removed from the drying chamber 12. Subsequently, the paper sheets to be dried are placed one by one on the grid 21 of the paper placement frame 2, allowing for the continuous placement of multiple sheets to improve processing efficiency.

[0029] Specifically, as a preferred embodiment, a grid 21 is provided in the paper placement frame 2. The grid 21 is made of copper and is used to transfer heat to the paper to accelerate the drying of the paper.

[0030] like Figure 2 As shown, the implementation includes: an upper drying rack 41 and a lower drying rack 42, which are respectively arranged on the top surface and the bottom surface of the drying chamber 12, and the ports of the upper drying rack 41 and the lower drying rack 42 are connected to the drying lamp board 4;

[0031] Specifically, as a preferred embodiment, an adjusting cylinder 13 is provided on the top surface of the drying chamber 12 and in the base 1. The rod ends of the two adjusting cylinders 13 are connected to the upper drying rack 41 and the lower drying rack 42 respectively, and are used to adjust the distance between the drying lamp board 4 in the upper drying rack 41 and the lower drying rack 42 and the cardboard to meet different drying requirements;

[0032] like Figure 1 As shown, in this embodiment, a ventilation duct 5 is further connected to the side of the drying chamber 12, and a ventilation slot is provided on one side surface of the ventilation duct 5, and a ventilation fan 51 is connected to the ventilation slot. By starting the ventilation fan 51, its rapidly rotating blades generate a negative pressure effect, accelerating the air flow, further enhancing the drying effect, thereby shortening the drying cycle and improving the overall production efficiency.

[0033] like Figures 1 to 3 As shown, it should be noted that in this embodiment, the drying lamp panel 4 in the application document is a single piece, and the number of sheets can be divided into several pieces. Before implementation, the speed of the DC servo motor is selected and set. This part is prior art and the working principle is already known. In addition, it should be noted that this application document only addresses the shortcomings of existing drying equipment that can only dry one side, has low drying efficiency, and is prone to uneven drying that affects the quality of the paper. It does not address other aspects. The following is an introduction to the working principle of this drying equipment for corrugated box production:

[0034] When using this new method, on-site staff will synchronously activate two DC servo motors to drive two sets of pulleys 31 and drive guide wheels 32 to rotate, thereby guiding the paper placement frame 2 to move out of the drying chamber 12. Subsequently, the paper to be dried is laid one by one on the grid 21 of the paper placement frame 2, supporting the continuous placement of multiple papers to improve processing efficiency.

[0035] After the paper is placed, the initial steps are repeated, and the two sets of drive guide wheels 32 work together to smoothly transport the screen frame loaded with paper back to the drying chamber 12. Once the screen frame 2 and the paper are fully in place, the side door (not shown) of the drying chamber 12 is closed.

[0036] Next, the regulating cylinders 13 installed on the upper and lower sides of the equipment are used to precisely control the lifting and lowering of the upper drying rack 41 and the lower drying rack 42, thereby adjusting the distance between the drying lamp board 4 and the surface and bottom of the paper to ensure the optimal distance setting for different drying requirements.

[0037] During the drying process, the upper and lower drying lamp panels 4 operate simultaneously, uniformly heating both sides of the paper (i.e., the top and bottom surfaces), significantly improving the drying uniformity and overall quality of the paper. Simultaneously, the ventilation fan 51 is activated, and its rapidly rotating blades create a negative pressure effect, accelerating air flow and further enhancing the drying effect, thereby shortening the drying cycle and improving overall production efficiency.

[0038] When drying is completed, the guide wheel 32 is driven repeatedly to guide the paper out, and the paper is removed to complete one drying operation.

[0039] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
