Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard production, in particular to a drying device for a corrugated cardboard production line. Background Art

[0002] Corrugated cardboard is a multi-layered, bonded structure consisting of at least one corrugated core (commonly known as "corrugated sheet," "corrugated paper," "corrugated core," "corrugated base") and one layer of cardboard (also known as "boxboard" or "boxboard"). It possesses high mechanical strength, capable of withstanding bumps and drops during transportation. The performance of a corrugated box depends on three factors: the properties of the core and cardboard, and the structure of the box itself.

[0003] During the production process, corrugated cardboard requires drying, which generates a large amount of moist, hot air. However, existing drying devices, such as those disclosed in Chinese patents CN216011603U and CN212320243U, directly exhaust this moist, hot air. This heat evaporates directly into the air, rendering it unusable and potentially wasting resources. Therefore, a drying device for a corrugated cardboard production line is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a drying device for a corrugated cardboard production line to solve the problems raised in the above background technology.

[0006] As a further preferred embodiment of the present technical solution, the plurality of transmission rollers are arranged in a linear array along the horizontal direction.

[0007] As a further preferred embodiment of the present technical solution, a thermal insulation layer is formed between the outer protective shell and the inner shell.

[0008] As a further preferred embodiment of the present technical solution, a plurality of air outlet holes are provided at the bottom of the outer protective shell.

[0009] As a further preferred embodiment of the present technical solution, two electric fans are fixedly mounted on the mounting plate, and the electric fans pass through the mounting plate.

[0010] As a further preferred embodiment of the present technical solution, the driving mechanism is composed of a motor, a fixed plate, a driving gear and a transmission gear. One end of each of the multiple transmission rollers extends to the outside of the inner shell and is fixedly connected to a driving gear. The driving gear is rotatably connected to the inner shell. A transmission gear is provided between two adjacent driving gears. The transmission gear is meshed with its adjacent driving gears. The transmission gear is rotatably connected to the outer wall of the inner shell. A motor is provided at the end of one of the driving gears. The motor is fixedly connected to the support frame through a fixed plate. The output shaft of the motor is fixedly connected to the center of the shaft end of the driving gear.

[0011] As a further preferred embodiment of the present technical solution, both the outer protective shell and the inner shell are made of fiberglass.

[0012] The utility model provides a drying device for a corrugated cardboard production line, which has the following beneficial effects:

[0013] The utility model can continuously heat the corrugated cardboard through the provided heating wire, transmission roller and driving mechanism, and can form a heat-insulating layer between the outer protective shell and the inner shell through the provided outer protective shell, and can absorb the moist hot air generated after the corrugated cardboard is dried into the heat-insulating layer through the provided fan, thereby playing a heat-insulating role for the interior of the inner shell, preventing the inner shell from directly contacting the outside world and causing rapid loss of internal heat, and the air outlet on the outer protective shell is located below the heat-insulating layer, which can ensure that the hot air will be squeezed out from the air outlet after filling the heat-insulating layer, so that the heat inside the heat-insulating layer can be retained for a long time.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a drying device for a corrugated cardboard production line includes a support frame 1, a mounting plate 2 is fixedly installed on the upper end of the support frame 1, an inner shell 4 is fixedly installed on the mounting plate 2, a feed port 10 and a discharge port 11 are respectively provided at both ends of the inner shell 4, a plurality of transmission rollers 12 are rotatably installed inside the inner shell 4, and the plurality of transmission rollers 12 are arranged in a linear array in the horizontal direction, a driving mechanism acting on the transmission rollers 12 is provided on the outer wall of the inner shell 4, a heating wire 13 is fixedly installed on the inner wall of the inner shell 4 below the transmission rollers 12, a fan 5 connected to the interior of the inner shell 4 is fixedly installed on the upper end of the inner shell 4, an outer protective shell 3 is provided on the outside of the inner shell 4 and is fixedly connected to the outer protective shell 3, and a thermal insulation layer is formed between the outer protective shell 3 and the inner shell 4.

[0022] A plurality of air outlet holes 15 are provided at the bottom of the outer protective shell 3 .

[0023] The vent holes 15 are provided to facilitate the discharge of hot air in the insulation layer. Since hot air will float upward, when the vent holes 15 are located at the bottom, it can be ensured that the insulation layer is fully filled with hot air before it is squeezed out from the vent holes 15.

[0024] Two electric fans 14 are fixedly mounted on the mounting plate 2 , and the electric fans 14 pass through the mounting plate 2 .

[0025] The electric fan 14 can quickly blow the hot air around the heating wire 13 toward the corrugated cardboard on the transmission roller 12.

[0026] Among them, the driving mechanism is composed of a motor 6, a fixed plate 7, a driving gear 8 and a transmission gear 9. One end of each of the transmission rollers 12 extends to the outside of the inner shell 4 and is fixedly connected to the driving gear 8. The driving gear 8 is rotatably connected to the inner shell 4. A transmission gear 9 is provided between two adjacent driving gears 8. The transmission gear 9 is meshed with its adjacent driving gear 8. The transmission gear 9 is rotatably connected to the outer wall of the inner shell 4. A motor 6 is provided at the end of one of the driving gears 8. The motor 6 is fixedly connected to the support frame 1 through the fixed plate 7. The output shaft of the motor 6 is fixedly connected to the center of the shaft end of the driving gear 8.

[0027] When in use, the starting motor 6 drives a driving gear 8 to rotate. Under the action of the transmission gear 9, the adjacent driving gears 8 will rotate synchronously, so that all driving gears 8 rotate synchronously, and then the transmission roller 12 starts to rotate and transports the corrugated cardboard.

[0028] Wherein, the outer shell 3 and the inner shell 4 are both made of glass fiber.

[0029] With such arrangement, the glass fiber has good heat insulation performance and can reduce the volatilization of heat inside the outer shell 3 and the inner shell 4.

[0030] The utility model provides a drying device for a corrugated cardboard production line, and the specific working principle is as follows:

[0031] During use, the heating wire 13 is energized to heat the air inside the inner shell 4, and then the corrugated cardboard is placed on the transmission roller 12, and the motor 6 is started to drive a drive gear 8 to rotate. Under the action of the transmission gear 9, the adjacent drive gears 8 will rotate synchronously, so that all the drive gears 8 rotate synchronously, and then the transmission roller 12 starts to rotate and transports the corrugated cardboard. The moist hot air generated after the corrugated cardboard is dried will be sucked away by the fan 5 and enter the insulation layer between the inner shell 4 and the outer protective shell 3. Since the hot air will float upward, and the air outlet 15 is located below the insulation layer, it can be ensured that the hot air will be squeezed out from the air outlet 15 only after filling the insulation layer, so that the heat inside the insulation layer can be retained for a long time, and the insulation layer filled with hot air can keep the inside of the inner shell 4 warm, preventing the inner shell 4 from directly contacting the outside world and causing rapid loss of internal heat.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
