Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard production equipment, in particular to a control device in the production of recycled corrugated paper. Background Art

[0002] In the production process of recycled corrugated paper, it is crucial to control the temperature and humidity of the environment. This is because the moisture absorption and release of paper will directly affect its quality and processing performance. For example, too low humidity may cause the paper to be too dry and easy to tear; too high humidity may make the paper too soft, affecting the printing and processing effect. At the same time, temperature will also affect the drying speed and dimensional stability of the paper.

[0003] However, traditional corrugated cardboard production equipment often lacks precise control of ambient temperature and humidity, especially the ability to control the cardboard in different zones or individually control the environment of small cardboards during the production process. This makes it difficult to ensure that each cardboard can achieve the best processing effect in a complex and changeable production environment. In view of this, we propose a control device for recycled corrugated paper production. Utility Model Content

[0024] A control device for the production of recycled corrugated paper includes a mounting plate 1 for mounting a conveyor belt 2 and a separately arranged water tank 9, a mounting cover 6 which can be moved up and down is arranged above the mounting plate 1, the mounting cover 6 is divided into a plurality of mounting chambers 62 by a plurality of partitions 61, a temperature and humidity sensor 63 is fixedly installed on the top of each mounting chamber 62, each mounting chamber 62 is provided with a movable plate 64 which can be moved forward and backward, the movable plate 64 is hollow inside and a diverter plate 65 is arranged at the bottom, a bellows 66 extending to the outside of the mounting cover 6 is arranged on the outer wall of the rear side of the movable plate 64, a plurality of bellows 66 are connected to the water tank 9 through a multi-outlet connecting pipe 7, and an electric heating network 97 for heating water is arranged in the water tank 9. The control device is divided into multiple installation bins 62 by an installation cover 6, and a temperature and humidity sensor 63 and a movable plate 64 are provided in each installation bin 62. The movable plate 64 is hollow inside and is provided with a diverter plate 65, which can control and adjust the temperature and humidity in each installation bin to meet the different requirements of environmental temperature and humidity in the production process of recycled corrugated paper. The setting of multiple installation bins 62 can control the temperature and humidity on a long cardboard in a zoned manner, and can also control multiple small cardboards individually, thereby increasing flexibility in use.

[0025] As a preferred embodiment of the present invention, a support leg 3 is fixedly mounted at each of the four corners of the bottom of the mounting plate 1. This can increase the stability of the device and support the mounting plate 1 at the same time.

[0026] As a preferred embodiment of the present invention, a U-shaped bracket 4 is fixedly connected to the top of the mounting plate 1, and two hydraulic cylinders 5 are symmetrically mounted on the U-shaped bracket 4, both for driving the mounting cover 6 to move up and down. Through the arrangement of the U-shaped bracket 4 and the hydraulic cylinder 5, the mounting cover 6 can be conveniently driven to move up and down, and the mounting cover 6 moves downward to press the corrugated cardboard against the conveyor belt 2, and at the same time, a protective pad 60 is fixedly connected to the bottom of the mounting cover 6, which can be used to protect the cardboard.

[0027] As a preferred embodiment of the present invention, a driving block 640 is integrally formed at the center of the top of the movable plate 64, a screw rod 67 threadedly connected to the driving block 640 is rotatably installed in the mounting cover 6, and an adjustment motor 8 for driving the screw rod 67 to rotate is installed on the outer wall of the mounting cover 6. Through the cooperation of the screw rod 67 and the driving block 640, the movable plate 64 can be driven to move forward and backward in the mounting bin, and then the cardboard in the mounting bin 62 can be sprayed to increase the humidity of the cardboard.

[0028] As a preferred embodiment of the present invention, a solenoid valve 70 is installed at each of the multiple pipe openings where the multi-outlet connecting pipe 7 is connected to the multiple bellows 66. By installing a solenoid valve at the pipe opening where the multi-outlet connecting pipe 7 is connected to the multiple bellows 66, the water vapor supply in each installation bin can be accurately controlled, thereby achieving accurate control of the temperature and humidity in each installation bin, and meeting the fine requirements for the environment during the production process.

[0029] As a preferred embodiment of the present invention, a water pumping pipe 90 connected to the multi-outlet connecting pipe 7 via a flange 91 is installed on the water tank 9, a water pump 93 is installed on the water pumping pipe 90, and a sealing cover 94 is installed on the water tank 9. By providing the water pumping pipe 90 and the water pump 93, the water in the water tank 9 can be pumped into the movable plate 64 to provide the required water vapor for the installation bin 62.

[0030] As a preferred embodiment of the present invention, an observation port 95 for observing the water level and a thermometer 96 are provided on the outer wall of the water tank 9. The arrangement of the observation port 95 and the thermometer 96 can conveniently observe the water level and water temperature in the water tank 9, so as to timely understand and adjust the working state of the water tank 9 to ensure the normal operation of the device.

[0031] As a preferred embodiment of the present invention, when the movable plate 64 moves in the installation cover 6, the bellows 66 is neither extended to the longest position nor retracted to the shortest position. Limiting the expansion and contraction range of the bellows 66 during the movement of the movable plate 64 can prevent the bellows 66 from being damaged due to excessive expansion and contraction, thereby improving the service life and reliability of the device. At the same time, it can also ensure that the temperature and humidity environment in the installation bin remains stable during the movement of the movable plate 64.

[0032] When the control device for recycled corrugated paper production of the utility model is used, first, the recycled corrugated paperboard to be processed is placed on the conveyor belt 2, and the conveyor belt 2 runs smoothly on the mounting plate 1 to deliver the paperboard into the working area of ​​the device.

[0033] Next, the installation cover 6 is driven by the hydraulic cylinder 5 to move downward until the corrugated cardboard is pressed against the conveyor belt 2 .

[0034] When the cardboard is fixed, the device starts to work. The temperature and humidity sensor 63 in each installation bin 62 monitors the temperature and humidity data in the bin in real time, and then adjusts the environment in each installation bin 62.

[0035] If the humidity of the paperboard needs to be increased, the control system will open the corresponding solenoid valve 70, start the water pump 93, and pump water from the water tank 9 through the pumping pipe 90. After being heated, the water is transported to the corresponding movable plate 64 through the multi-outlet connecting pipe 7 and the bellows 66. The hollow structure inside the movable plate 64 and the diverter plate 65 at the bottom ensure that the water can be evenly distributed, and through the spraying function of the movable plate 64, the water mist is sprayed onto the paperboard, thereby increasing the humidity of the paperboard.

[0036] At the same time, by adjusting the motor 8 to drive the screw rod 67 to rotate, the front and rear positions of the movable plate 64 in the installation chamber 62 can be accurately controlled to ensure the uniformity and coverage of the spraying.

[0037] During the entire processing process, the control system continuously monitors and adjusts the temperature and humidity environment of each installation bin 62 to adapt to the different requirements of environmental temperature and humidity during the production of recycled corrugated paper. This partition control method can not only perform differentiated processing on different areas on a long cardboard, but also control multiple small cardboards separately at the same time, greatly improving the flexibility and efficiency of production.

[0038] When the cardboard is processed, the hydraulic cylinder 5 drives the mounting cover 6 to move upward again to release the cardboard. Then, the conveyor belt 2 sends the processed cardboard out of the working area to complete the entire processing process.

[0039] At the same time, the electric heating net 97 in the water tank 9 can heat the water, thereby adjusting the temperature of the paperboard while adjusting the humidity.
