[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4This utility model provides an embodiment of a packaging paper dewatering device, including a dewatering roller 1, a support rod 4, and a drive assembly. The support rod 4 is provided on the inner side of the dewatering roller 1, and the dewatering roller 1 and the support rod 4 are rotatably and sealedly connected. A support base 2 is provided at the bottom of the dewatering roller 1, and the two ends of the support rod 4 are fixedly connected to the support base 2. A drive assembly is provided at the bottom of the support base 2. The dewatering roller 1 is provided in multiple sets and divided into two rows. The spacing between the dewatering rollers 1 in the same vertical direction gradually decreases. Air vents 8 are opened on the surface of the dewatering roller 1. A compressed air tank 5 is provided on one side of the support base 2. By setting the dewatering rollers 1 with gradually decreasing spacing, it is prevented that the pressure of the dewatering roller 1 at a single position is too great, causing the paper to adhere to the surface of the dewatering roller 1. In addition, multiple sets of very small air vents 8 are opened on the surface of the dewatering roller 1, and the compressed air tank 5 is used to pressurize the dewatering roller 1 to help separate the material from the dewatering roller 1 and prevent the packaging paper from being damaged due to some paper adhering to the surface of the dewatering roller 1.

[0022] Please see Figure 2 In this embodiment, pulleys 101 are provided on both sides of the dewatering roller 1, and a transmission belt 102 is provided between the pulleys 101 of the two sets of dewatering rollers 1. A transmission gear 103 is provided on the same side of the two sets of dewatering rollers 1, and the transmission gears 103 mesh with each other. The drive assembly includes a drive motor 3 and a reducer 301. The drive motor 3 is provided at the bottom of the support base 2, and a reducer 301 is provided on one side of the drive motor 3. The output end of the drive motor 3 is connected to the input end of the reducer 301. The drive motor 3 outputs power to the reducer 301, and the reducer 301 increases the torque of the power. The transmission belt 102 and the transmission gear 103 drive the dewatering rollers 1 in the same row to rotate in the same direction, and make the two rows of dewatering rollers 1 rotate in opposite directions, so as to convey and apply pressure to the material entering the device range.

[0023] Please see Figures 3-4 In this embodiment, connecting seats 502 are provided at both ends of the support rod 4. The connecting seats 502 are fixedly connected to the support base 2 and are interconnected with all the support rods 4. An air supply pipe 501 is provided between the connecting seats 502 and the compressed air tank 5. An air compressor 503 is provided above the compressed air tank 5. An electric heating tube 6 is provided on the inner side of the dehydration roller 1 and is fixedly connected to the support rod 4. A flow hole 7 is opened on the inner side of the support rod 4 and the diameter of the air outlet 8 is much smaller than that of the flow hole 7.

The compressed air tank 5 injects gas into all the support rods 4 through the air supply pipe 501 and the connecting seat 502. The gas enters the internal space of the dewatering roller 1 through the flow hole 7 and is pressurized. The electric heating tube 6 heats the air in the dewatering roller 1 and increases the temperature of the dewatering roller 1, thereby accelerating the dewatering speed of the material. At the same time, the high-pressure gas in the dewatering roller 1 is continuously released from the air outlet 8 to help the material separate from the dewatering roller 1 and prevent the material from adhering to the surface of the dewatering roller 1.

[0024] During use, the drive motor 3 outputs power to the reducer 301, which increases the torque of the power. The transmission belt 102 and the transmission gear 103 drive the dewatering rollers 1 in the same row to rotate in the same direction, and make the two rows of dewatering rollers 1 rotate in opposite directions. This conveys and applies pressure to the material entering the device. The air compressor 503 compresses air and stores it in the compressed air tank 5. The compressed air tank 5 injects gas into all the support rods 4 through the air supply pipe 501 and the connecting seat 502. The gas enters the internal space of the dewatering roller 1 through the flow hole 7 and is pressurized. The electric heating tube 6 heats the air inside the dewatering roller 1 and increases the temperature of the dewatering roller 1, thereby accelerating the dewatering speed of the material. At the same time, the high-pressure gas inside the dewatering roller 1 is continuously released from the air outlet 8, which helps the material separate from the dewatering roller 1 and prevents the material from adhering to the surface of the dewatering roller 1.
