Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a corrugated cardboard drying device. Background Technology

[0002] In the production and processing of corrugated cardboard, the drying process is a crucial step in ensuring cardboard quality. Its effectiveness directly affects the strength, flatness, and subsequent processing performance of the cardboard. Traditional corrugated cardboard drying equipment typically uses hot air circulation to dry the cardboard. However, since the cardboard is placed on a conveyor belt and moved forward, the contact surface between the cardboard and the conveyor belt may not be sufficiently dried. Residual moisture can affect the strength of the cardboard, and uneven drying can easily lead to deformation and warping in subsequent processing, reducing product quality and production efficiency. Some drying equipment uses microwave drying. Compared to hot air drying equipment, microwave drying equipment can dry corrugated cardboard more evenly, but its equipment cost and subsequent maintenance costs are higher, and its power consumption is also greater.

[0025] like Figures 1-4 As shown, this utility model provides a corrugated cardboard drying device. Its base 1 adopts a U-shaped metal structure. Two symmetrical flipping structures 2 are arranged in the middle of the bottom inner side of the base 1. In each flipping structure 2, the bracket 201 is fixed to the base 1 by bolts. The first main shaft 202 and the first secondary shaft 203 are rotatably mounted on the bracket 201 through bearings. The first main shaft 202 is located directly below the first secondary shaft 203. Synchronous pulleys 204 are installed on both shafts and are connected by synchronous belts 205. The synchronous pulleys 204 on the two shafts are of different sizes to increase the wrap angle and prevent the synchronous belt 205 from slipping. A protective cover is installed on the side of the bracket 201 and outside the two synchronous pulleys 204 and the synchronous belt 205 by screws to protect the synchronous pulleys 204 and the synchronous belt 205. A flipping component 206 is fixedly installed on the first secondary shaft 203. The flipping component 206 is plate-shaped and has grooves on the front and rear sides for corrugated cardboard to be inserted. The first main shafts 202 of the two flipping structures 2 are connected by couplings.

[0026] The second main shaft 3 and the second auxiliary shaft 4 are rotatably mounted on the inner side of the base 1 via bearings. Each shaft is equipped with three pulleys 5. The pulleys 5 on the two shafts correspond to each other and are connected by a conveyor belt 6. The two flipping structures 2 are located between the two conveyor belts 6. A tensioner is provided on the inner side of the base 1 to tension the conveyor belt 6 to prevent the conveyor belt 6 from slipping. The height of the upper surface of the conveyor belt 6 is consistent with the height of the groove of the flipping component 206 when it is horizontal, so as to ensure that the cardboard can be inserted into the groove of the flipping component 206 when the conveyor belt 6 transports the corrugated cardboard.

[0027] Two drive mechanisms 7 are installed on the side of the base 1. Each drive mechanism 7 consists of a servo motor and a reducer. The output shaft of the servo motor is connected to the input shaft of the reducer. The output shafts of the two reducers are connected to the first main shaft 202 and the second main shaft 3 respectively through couplings. The drive mechanism 7 connected to the first main shaft 202 can drive the first main shaft 202 to rotate. Then, through the cooperation of the synchronous pulley 204 and the synchronous belt 205, it drives the first auxiliary shaft 203 to rotate, thereby driving the flipping part 206 to flip. The drive mechanism 7 connected to the second main shaft 3 can drive the second main shaft 3 to rotate, thereby driving the conveyor belt 6 to rotate through the cooperation of the second auxiliary shaft 4 and the pulley 5.

[0028] The base 1 is bolted to the top of a first cover 8 and two drying structures 9. The first cover 8 is located directly above the two flipping structures 2. It has notches on its front and rear bottom sides for corrugated cardboard to pass through. Photoelectric sensors are installed inside to monitor the position of the corrugated cardboard within the first cover 8 in real time. The two drying structures 9 are located on the front and rear sides of the first cover 8, respectively. In each drying structure 9, a second cover 901 is bolted to the base 1. It also has notches on its front and rear bottom sides for corrugated cardboard to pass through, aligned with the notches on the first cover 8. An air inlet is located on its top. Multiple evenly distributed air outlets are opened on the lower part of the left and right sides. A flow equalization plate 902 is welded to the upper inner side of the second cover 901, and a hot air blower 903 is installed on its top. The output end of the hot air blower 903 is connected to the air inlet through a pipe. A temperature sensor is also installed inside the second cover 901 to monitor the internal ambient temperature of the second cover 901 in real time. Hot air can be delivered into the second cover 901 through the hot air blower 903, and then the hot air is evenly output downward through the flow equalization plate 902, thereby achieving the drying of corrugated cardboard. Excess hot air can be discharged through the air outlets on both sides of the second cover 901.

[0029] A control console is set next to the base 1. The control console is connected to the servo motor, hot air blower 903, photoelectric sensor and temperature sensor via cables. When working, the servo motor can be started by the control console to drive the conveyor belt 6 and the flipping part 206 to operate. At the same time, the hot air blower 903 can be started to deliver hot air into the drying structure 9.

[0030] Working principle and usage process of this utility model:

[0031] When using this corrugated cardboard drying device, first connect the device to the power supply, and start the hot air blower 903 of the drying structure 9 through the control panel next to the base 1. The hot air blower 903 starts working and delivers hot air through the pipe to the second cover 901. The hot air is evenly dispersed by the flow equalization plate 902 and blown downward to preheat the internal environment of the second cover 901. After preheating, the drive mechanism 7 connected to the second main shaft 3 is controlled by the control panel to operate. The servo motor drives the second main shaft 3 to rotate through the reducer, which in turn drives the conveyor belt 6 to rotate. The corrugated cardboard to be dried is placed on the conveyor belt 6 at the front of the inner side of the base 1. The conveyor belt 6 continuously conveys the corrugated cardboard. The corrugated cardboard first passes through the inside of the first second cover 901 to achieve drying on the corrugated cardboard.

[0032] Then the cardboard enters the first housing 8, and the conveyor belt 6 continues to transport the corrugated cardboard until the cardboard is inserted into the groove on the front side of the flipper 206. After the photoelectric sensor detects that the cardboard has been inserted into the groove, it sends a signal to the control console. The control console controls the drive mechanism 7 connected to the first main shaft 202 to operate. The servo motor drives the first main shaft 202 to rotate through the reducer. The first main shaft 202 drives the first secondary shaft 203 and the flipper 206 on it to rotate 180° through the synchronous pulley 204 and the synchronous belt 205, so that the corrugated cardboard is flipped 180 degrees with the flipper 206, thus realizing the flipping of the corrugated cardboard.

[0033] The flipped corrugated cardboard continues to be conveyed by conveyor belt 6 and then passes through the inside of the second second cover 901 to achieve drying of the underside of the corrugated cardboard. After drying, the corrugated cardboard is conveyed by conveyor belt 6 to the rear of the device and removed.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
