Description

Technical Field

[0001] This utility model belongs to the technical field of packaging box production equipment, and specifically relates to a packaging box drying and curing device. Background Technology

[0002] The drying and curing of packaging boxes are core processes for ensuring their performance, quality, and service life, directly affecting their structural stability, durability, surface quality, and application safety. The drying process essentially removes residual free moisture from the raw materials or processing steps, resolving various quality issues caused by excessive moisture. The curing process targets coatings, printing inks, or internal adhesives on the packaging box surface, using physical or chemical actions to harden and set them, focusing on enhancing surface properties and stabilizing bond strength.

[0003] Current processes typically involve first drying the packaging boxes using drying equipment, then transferring them to curing equipment for curing. This impacts production efficiency and requires a large footprint. While some integrated drying and curing systems exist, they lack sealing at the inlet and outlet, resulting in significant heat loss and high energy consumption. Furthermore, they suffer from uneven internal airflow circulation and dead zones beneath the material.

[0004] Therefore, the above-mentioned problems have become technical issues that urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above deficiencies, this utility model provides a packaging box drying and curing device, which aims to solve the above technical problems.

[0006] Technical solution: In order to achieve the above objectives, the present invention provides a packaging box drying and curing device, including a frame, a drying box and a curing box arranged side by side on the frame, and a conveying component on the frame, wherein the packaging box can be transferred between the drying box and the curing box through the conveying component; The drying chamber includes a drying cavity and a circulation device communicating with the drying cavity; the curing chamber includes a curing cavity and a curing device communicating with the curing cavity; and the conveying assembly has gaps between itself and the bottom surfaces of both the drying cavity and the curing cavity. Both sides of the drying chamber and the curing chamber are equipped with gate assemblies for sealing the drying chamber and the curing chamber.

[0007] The packaging box is first conveyed into the drying chamber by the conveyor assembly. In the drying chamber, the free moisture remaining in the raw materials or during the processing of the packaging box is removed by heating and air circulation. Then, it is conveyed into the curing chamber by the conveyor assembly, where the coating and adhesive layer are cured.

[0008] Furthermore, a heating element is provided inside the drying chamber, and the circulation device includes a set of circulating fans vertically arranged on the drying chamber. A fan hood is provided outside the circulating fans, and the fan hood communicates with both the outside environment and the drying chamber. A drive motor connected to the circulating fans is mounted on the fan hood. The heating element and the circulating fans create a hot air circulation within the drying chamber.

[0009] Furthermore, the set of circulating fans are arranged perpendicular to each other, and their air outlets and air inlets are arranged in opposite directions to form a circulating air path in the drying chamber.

[0010] Furthermore, the curing device includes a mounting box located above the interior of the curing chamber. From bottom to top, the mounting box contains a heating chamber and an air inlet chamber. The heating chamber contains heating pipes, and its bottom is a mesh plate. The air inlet chamber contains a fan. The top of the mounting box contains a control box for controlling the heating pipes and a fan motor connected to the fan. The heating pipes provide heat to the curing chamber, while the fan blows hot air onto the packaging box to aid in curing.

[0011] Furthermore, the mounting box is also equipped with an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to the air inlet chamber, and the air outlet pipe is connected to the curing chamber. Both the air inlet pipe and the air outlet pipe are equipped with airflow regulating valves. By adjusting the airflow regulating valves, the airflow can be adjusted, thereby assisting in controlling the internal temperature of the curing chamber and allowing for a wider range of adjustment of the curing process parameters.

[0012] Furthermore, the gate assembly includes a gate plate, with a cylinder connected to the top of the gate plate. Guide rails are connected to both sides of the gate plate via sliders, and these guide rails are mounted on the drying chamber and curing chamber. The bottom of the gate plate has a groove that mates with the conveying assembly. The gate plate can seal the drying chamber and curing chamber separately.

[0013] Furthermore, the conveying assembly includes a set of parallel flow strips and several support rods, the support rods and flow strips being arranged alternately, and a mesh plate is provided below the conveying assembly.

[0014] Furthermore, the drying chamber and curing chamber are equipped with temperature and humidity sensors for monitoring temperature and humidity.

[0015] Furthermore, a row of axial flow fans is provided between the drying chamber and the curing chamber, and the axial flow fans are located below the conveying assembly and communicate with the bottom of the frame.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The present invention provides a packaging box drying and curing device, which is an integrated unit that can simultaneously dry and cure packaging boxes. It has a small footprint, avoids reduced production efficiency due to transportation, and eliminates the transportation process. The immediate curing after drying reduces heat loss from the packaging boxes and results in higher curing efficiency.

[0017] 2. In addition, this utility model is equipped with gate components at the inlet and outlet of both the drying chamber and the curing chamber. During operation, the gate components can close the drying chamber and the curing chamber to reduce heat loss and lower energy consumption. At the same time, the packaging box is placed on the conveying component. Hot air in both the drying chamber and the curing chamber can pass through the conveying component to the gap between the conveying component and the box body, which can dry or cure the bottom of the packaging box. The drying chamber is equipped with mutually perpendicular circulating fans, and the curing chamber is equipped with air outlet pipes and air inlet pipes on opposite sides, which can form hot air circulation in the box body, achieving almost no dead corners.

Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figure 1-8 As shown: A packaging box drying and curing device includes a frame 1, a drying box 2 and a curing box 3 arranged side by side on the frame 1, and a conveying assembly 4 provided on the frame 1, through which the packaging box can be transferred between the drying box 2 and the curing box 3; The drying chamber 2 includes a drying cavity 21 and a circulation device 22 connected to the drying cavity 21. The curing chamber 3 includes a curing cavity 31 and a curing device 32 connected to the curing cavity 31. There are gaps between the conveying component 4 and the bottom surfaces of the drying cavity 21 and the curing cavity 31. Hot air can flow to the bottom of the conveying component 4 to dry or cure the bottom of the packaging box, thereby improving uniformity. Both sides of the drying chamber 21 and the curing chamber 31 are provided with gate assemblies 33 for sealing the drying chamber 21 and the curing chamber 31.

[0022] The drying chamber 21 is equipped with a heating element, and the circulation device 22 includes a set of circulating fans 221 vertically mounted on the drying chamber 21. A fan hood 222 is provided on the outside of the circulating fans 221, communicating with both the outside environment and the drying chamber 21. A drive motor connected to the circulating fans 221 is mounted on the fan hood 222. The heating element can be located on the inner wall of the drying chamber 21. The heat generated by the heating element dries the packaging box. Simultaneously, the circulating fans 221 draw outside air into the drying chamber 21 and expel air from the drying chamber 21, thereby creating a high-temperature and high-speed airflow within the drying chamber 21 to quickly remove moisture from the packaging box.

[0023] Specifically, the set of circulating fans 221 are arranged perpendicularly to each other, and their air outlets and air inlets are arranged in opposite directions, forming a circulating air path in the drying chamber 21.

[0024] The curing device 32 includes a mounting box located above the interior of the curing chamber 31. From bottom to top, the mounting box contains a heating chamber 341 and an air inlet chamber 342. The heating chamber 341 contains a heating tube 321, and its bottom is a mesh plate. The air inlet chamber 342 contains a fan wheel 322. The top of the mounting box contains a control box for controlling the heating tube 321 and a fan wheel motor connected to the fan wheel 322. After the heating tube 321 is activated, it generates high-temperature gas in the heating chamber 341. This high-temperature gas can pass through the mesh plate and enter the curing chamber through the fan wheel 322. The fan wheel 322 draws in air through the air inlet chamber 342, and the gas rapidly heats up after passing through the heating chamber 341 and acts on the curing chamber 31.

[0025] In addition, the mounting box is equipped with an air inlet pipe 323 and an air outlet pipe 324. The air inlet pipe 323 is connected to the air inlet chamber 342, and the air outlet pipe 324 is connected to the curing chamber 31. Both the air inlet pipe 323 and the air outlet pipe 324 are equipped with airflow regulating valves. The entire curing chamber 3 takes in air through the air inlet pipe 323 and exhausts air through the air outlet pipe 324. Adjusting the airflow regulating valves can adjust the intake and exhaust volumes. By adjusting different intake and exhaust volumes, the temperature inside the curing chamber 31 can be adjusted. Temperature adjustment does not only depend on adjusting the temperature of the heating element 321, making the adjustable range wider.

[0026] The gate assembly 33 includes a gate plate 331, with a cylinder 332 connected to the top of the gate plate 331. Guide rails 333 are connected to both sides of the gate plate 331 via sliders. The guide rails 333 are mounted on the drying chamber 2 and the curing chamber 3. A groove is provided at the bottom of the gate plate 331 to fit with the conveying assembly 4. The cylinder 332 can drive the gate plate 331 to open or close. When the gate plate 331 is closed, it allows the drying chamber 21 and the curing chamber 31 to form a relatively closed cavity, which helps to retain heat and save energy. When open, the packaging box can be transferred on the conveying assembly.

[0027] Specifically, the conveying component 4 includes a set of parallel flow strips 41 and several support rods 42, the support rods 42 and the flow strips 41 are arranged alternately, and a mesh plate is provided below the conveying component 4.

[0028] The drying chamber 2 and curing chamber 3 are equipped with temperature and humidity sensors to monitor temperature and humidity in order to achieve the required process conditions.

[0029] In addition, a row of axial flow fans 5 is provided between the drying chamber 2 and the curing chamber 3. The axial flow fans 5 are located below the conveying assembly 4 and communicate with the lower part of the frame 1. The electrical components of the entire equipment are located below the frame 1, and the axial flow fans 5 can dissipate the heat generated during equipment operation.

[0030] Taking a paper packaging box as an example, the working principle of this utility model is explained as follows: The packaging box enters the drying chamber 2 through the conveying component 4. The heating element heats up to the set temperature, allowing the packaging box to dry in an environment of 50-80℃. After drying, it is conveyed into the curing chamber 3 through the conveying component 4. The heating tube 321 in the curing chamber 3 cures the packaging box at 120-180℃, while further removing any remaining moisture from the packaging box.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
