Description

Technical Field

[0001] This utility model belongs to the field of paper box processing technology, and specifically relates to a paper box drying device. Background Technology

[0002] During the processing of cardboard boxes, the cardboard is bonded with composite adhesive, which can easily cause the molded cardboard boxes to be relatively damp, with a moisture content generally as high as 20-30%. This results in poor strength of the cardboard boxes. Therefore, the cardboard needs to be air-dried naturally before the strength of the cardboard boxes can be increased.

[0003] Existing cardboard drying equipment, while meeting the basic requirements for drying cardboard by placing it on a mesh support structure, results in the cardboard remaining relatively stationary relative to the mesh support structure during the drying process. Consequently, areas of the cardboard not covered by the mesh support structure cannot be directly dried, leading to faster drying efficiency for the mesh-covered areas compared to the non-mesh-covered areas. This ultimately affects the overall drying efficiency of the cardboard and fails to fully meet user needs. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a paper box drying device that not only meets the basic requirements for drying paperboard, but also allows the paperboard to move relative to the mesh placement structure, thereby ensuring that the drying efficiency of the paperboard is the same for the mesh area and the non-mesh area of ​​the mesh placement structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a paper box drying device, including a drying box, a door hinged to the front end of the drying box, an exhaust pipe at the top of the drying box, a drying component on the inner side wall of the drying box, a mounting shaft rotatably mounted on the top of the drying box, a placement plate mounted on the mounting shaft, multiple outward-facing placement mesh slots around the mounting shaft on the placement plate, vertical rods extending through and slidingly into the multiple placement mesh slots on the placement plate, push plates at the upper ends of the multiple vertical rods respectively, and mounting ring plates at the lower ends of the multiple vertical rods together, and a telescopic push rod horizontally mounted at the bottom of the drying box, with a support ring groove rotatably connected to the mounting ring plate on the output shaft of the telescopic push rod.

[0006] As a further improvement of this utility model, a driven gear is provided on the mounting shaft located on the lower side of the drying chamber, and a drive motor is also provided at the bottom of the drying chamber, with a driving gear meshing with the driven gear on the output shaft of the drive motor.

[0007] As a further improvement of this utility model, a connecting slot located at the side end of the telescopic push rod is also vertically provided on the bottom inner wall of the drying oven, and a connecting plate that is inserted into the connecting slot is provided at the bottom of the support ring groove.

[0008] As a further improvement of this utility model, an exhaust fan is also provided on the exhaust pipe. The top of the drying chamber is equipped with an exhaust pipe and an exhaust fan, which can effectively remove moisture and maintain air circulation inside the chamber.

[0009] As a further improvement of this utility model, the drying component is a far-infrared heating plate or a heating lamp.

[0010] As a further improvement of this invention, the bottom of the drying oven is also provided with support legs. The support legs provide stable support.

[0011] As a further improvement to this invention, a transparent observation window is also provided on the door. This window allows operators to easily monitor the drying process at any time, ensuring smooth production.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the mounting shaft can drive the placement plate, placement mesh trough, and multiple cardboard sheets to rotate, allowing the drying assembly to dry the cardboard sheets thoroughly and evenly. Simultaneously, the telescopic push rod and support ring groove can vertically adjust the mounting ring plate, multiple vertical rods, and push plate, thereby adjusting the vertical position of the cardboard sheets in the placement mesh trough. This allows for flexible adjustment of the cardboard sheets' position relative to the placement mesh trough during the drying process, ensuring that the drying efficiency of the cardboard sheets is the same for both the mesh and non-mesh areas of the mesh placement structure.

[0014] Secondly, the design of the connecting slot and the insert plate enhances the stability of the support ring groove and prevents the telescopic push rod from being easily damaged by non-vertical forces. Attached Figure Description

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figures 4 and 5, a paper box drying device includes a drying chamber 101. A door 102 is hinged to the front end of the drying chamber 101. An exhaust pipe 103 is located on the top of the drying chamber 101. A drying assembly is mounted on the inner wall of the drying chamber 101. A mounting shaft 104 is vertically inserted through and rotatably mounted on the bottom of the drying chamber 101. A through hole is provided at the bottom of the drying chamber 101 for rotatable connection with the mounting shaft 104. A bearing 105 is located at the bottom of the drying chamber 101. The outer ring of the bearing 105 is connected to the outer wall of the bottom of the drying chamber 101, and the inner ring of the bearing 105 is connected to the mounting shaft 104. The mounting shaft 104 is fixed with... A placement plate 106 is attached, and multiple outward-facing placement mesh slots 107 are fixedly connected to the placement plate 106 around the mounting shaft 104. Vertical rods 108 extend through the placement plate 106 and slide into the multiple placement mesh slots 107. The placement plate 106 has connecting sliding holes that are slidably connected to the vertical rods 108. Push plates 109 are respectively provided at the upper ends of the multiple vertical rods 108, and mounting ring plates 110 are provided at the lower ends of the multiple vertical rods 108. A telescopic push rod 111 is horizontally provided at the bottom of the drying oven 101. A support ring groove 112 that is rotatably connected to the mounting ring plate 110 is provided on the output shaft of the telescopic push rod 111.

[0024] In this embodiment, the drying component is a far-infrared heating plate; in another embodiment, the drying component may also be a heating lamp.

[0025] The worker first opens the hinged door 102 at the front of the drying chamber 101, and places the cardboard to be dried into the multiple placement slots 107 on the placement plate 106. Then, the far-infrared heating plate is activated to begin the heating and drying process. This process uses uniform radiant heat to quickly evaporate the moisture inside the cardboard. The moisture generated during the drying process is discharged through the exhaust pipe 103 at the top, thus achieving the drying treatment of the cardboard in the placement slots 107.

[0026] At the same time, the mounting shaft 104, the placement plate 106, the placement mesh groove 107 and the paper box therein can be driven to rotate. This rotational motion ensures that the drying assembly can dry the paper box thoroughly and evenly.

[0027] Furthermore, the worker can drive the output shaft of the telescopic push rod 111 to extend by a certain length, pushing the support ring groove 112 upward, which in turn drives the mounting ring plate 110, multiple vertical rods 108, and push plate 109 to perform vertical adjustment. This adjustment can flexibly change the vertical position of the paper box in the placement slot 107, so that different parts of the paper box can obtain the same drying efficiency, especially for the mesh area and non-mesh area.

[0028] After the drying process is complete, open the box door 102 and remove the cardboard from the placement mesh 107.

[0029] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, a driven gear 201 located below the drying chamber 101 is fixedly connected to the mounting shaft 104. A drive motor 202, a geared servo motor, is also vertically fixed to the bottom of the drying chamber 101. The output shaft of the drive motor has a driving gear 203 that meshes with the driven gear 201. By simply starting the drive motor 202, the mounting shaft 104 can be rotated through the transmission between the driving gear 203 and the driven gear 201.

[0030] According to another embodiment of the present invention, such as Figure 5 As shown, a connecting slot 301 located at the side end of the telescopic push rod 111 is vertically provided on the inner side wall of the bottom of the drying oven 101, and a connecting plate 302 that is inserted into the connecting slot 301 is provided at the bottom of the support ring groove 112. Through the vertical insertion and cooperation between the connecting plate 302 and the connecting slot 301, the support ring groove 112 can be kept stable, and the telescopic push rod 111 can be prevented from being easily deformed and damaged by non-vertical forces.

[0031] According to another embodiment of the present invention, such as Figure 2 As shown, an exhaust fan 303 is also installed on the exhaust pipe 103, and the bottom of the exhaust fan 303 is connected to the top of the drying chamber 101. The exhaust fan 303 can be started to accelerate the removal of moisture, maintain air circulation inside the drying chamber 101, and improve drying efficiency.

[0032] According to another embodiment of the present invention, such as Figure 1 As shown, a support leg 304 is also fixed to the bottom of the drying oven 101. The support leg 304 provides stable support for the device.

[0033] According to another embodiment of the present invention, such as Figure 1 As shown, a transparent observation window 305 is also installed on the door 102. Through the transparent observation window 305, operators can easily check the drying process at any time to ensure smooth production.

[0034] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
