Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying equipment for corrugated cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes are usually used as wrapping materials for goods or as outer protective materials for items. After the glue is sprayed onto the cardboard box, a drying device is needed to dry the glue.

[0003] An existing drying device for cardboard box production (publication number: CN211177837U) has at least the following drawbacks: In the aforementioned patent, a conveyor belt structure is used when conveying corrugated cardboard. The conveyor belt is generally a mesh belt. However, the mesh belt is always in contact with the corrugated paper, resulting in poor airflow and obstruction of hot air circulation. This can easily lead to incomplete drying at the bottom, requiring an increase in drying time to ensure the drying effect. Therefore, it is necessary to propose a drying device for corrugated cardboard box production to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drying device for corrugated cardboard box production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drying device for corrugated cardboard box production includes a drying chamber. A conveyor belt is fixedly installed on the inner bottom surface of the drying chamber. A PLC controller is fixedly installed on one side of the drying chamber. The device also includes a drying assembly for drying the corrugated cardboard boxes. The drying assembly includes two L-shaped plates, both of which are installed on the inner bottom surface of the drying chamber. Several rotating rods are arranged between the two L-shaped plates. Rotating shafts are installed on both sides of each rotating rod. Several first circular through holes are opened on one side of the drying chamber, and the first circular through holes are movably connected to the rotating shafts. A second bevel gear is fixedly sleeved on the outer circular wall of one end of the rotating shaft. Several fixing plates are fixedly installed on one side of the L-shaped plate on the right side. A second circular through hole is opened on one side of the fixing plate. A transmission rod is movably sleeved on the inner circular wall of the second circular through hole. Several first bevel gears are fixedly sleeved on the outer circular wall of the transmission rod. The first bevel gears mesh with the second bevel gears. A drive motor is fixedly installed on one side of the drying chamber on the right side. One end of the drive shaft of the drive motor is fixedly installed with the transmission rod. The drive motor is electrically connected to the PLC controller.

[0006] As a further embodiment of this utility model, a number of support plates are fixedly installed on the top surface of the drying chamber to support the corrugated cardboard.

[0007] As a further embodiment of this invention, the top surface of the rotating rod frame is higher than the top surface of the support plate.

[0008] As a further embodiment of this utility model, a rectangular through hole is provided on the top surface of the support plate.

[0009] As a further embodiment of this utility model, the top and bottom surfaces of the drying chamber are respectively connected to hot air inlet pipes, and the top surface of the drying chamber is provided with an exhaust pipe for discharging hot and humid gas.

[0010] As a further embodiment of this utility model, two baffles are fixedly installed inside the drying chamber, and a strip is fixedly installed on the bottom surface of the baffles.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This drying device for corrugated cardboard box production uses a rotating frame to lift the corrugated paper, which is alternately supported by a support plate. This ensures that there are no continuous obstructions at the bottom of the corrugated paper. As the paper moves slowly, it is continuously lifted and supported, achieving thorough heating and drying at the bottom. This avoids uneven drying caused by prolonged contact between certain areas and the conveyor belt, indirectly increasing the drying speed. Attached Figure Description

[0019] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: When the corrugated cardboard needs to be dried in the drying chamber 1, the corrugated cardboard is conveyed by the conveyor belt 2, which is a mesh belt. At the same time, the initial glue setting is performed. The drive motor 11 is started, which drives the transmission rod 8 to rotate the first bevel gear 9, the second bevel gear 10, and the rotating shaft 6, thereby causing the rotating frame 5 to rotate. Simultaneously, air is introduced and exhausted through the hot air inlet pipe 13 and the exhaust pipe 12. Initial drying is carried out using the existing air blowing method. At this time, the glue is initially formed. When it reaches the middle position, the top crossbar of the rotating frame 5 lifts the corrugated cardboard and pushes it towards the outlet. When the rotating frame 5 rotates below the top surface of the support plate 4, the corrugated cardboard is supported by the support plate 4. While the corrugated cardboard moves slowly, air is introduced through the hot air inlet pipe 13 at the bottom to dry the bottom of the corrugated cardboard. During the continuous lifting and movement of the corrugated cardboard, there are no obstructions at the bottom, and the airflow is smooth, which can fully heat and dry the bottom surface until it exits from the right outlet of the drying chamber 1, thus completing the drying process.

[0020] It should be noted that during production, the length ratio of the conveyor belt 2 and the drying component can be adjusted according to actual conditions; the outer skin of the rotating frame 5 can be fitted with a silicone sleeve to protect and improve friction; the existing technology for hot air blowing angle and speed is a mature technology, such as the top and side blowing used in the Chinese patent document (CN211177837U), as well as other methods, which are not the focus of this application and will not be elaborated here.
