Description

Technical Field

[0001] This utility model relates to the field of papermaking machinery, and in particular to a vacuum suction roller for a papermaking machine. Background Technology

[0002] A vacuum suction transfer roller for papermaking machines utilizes vacuum adsorption to smoothly transfer wet paper sheets from the wire section to the press blanket during the papermaking process, preventing paper sheet breakage or wrinkling. At the same time, by uniformly distributing pressure, it enhances the dewatering efficiency of the press section, improving the dryness and strength of the paper. It also reduces slippage between the paper sheet and the blanket, ensuring paper uniformity and surface quality, thus helping to improve papermaking production efficiency and product quality.

[0003] An existing vacuum suction roller for papermaking machines can dilute the filler in the suction area by spraying water, allowing the filler to be carried away by the vacuum system and preventing filler accumulation and suction blockage. However, it does not consider the recycling of the filler in the suction holes. For example, Chinese patent "A Vacuum Suction Roller for Papermaking Machine" (application number "CN202022590789.4") can dilute the filler in the suction area by spraying water, allowing the filler to be carried away by the vacuum system and preventing filler accumulation and suction blockage. However, it does not consider the recycling of the filler in the suction holes, resulting in poor device performance. Utility Model Content

[0013] Beneficial effects

[0014] Compared with existing technologies, this vacuum suction roller for papermaking machines utilizes a vacuum box and an internal vacuum chamber that work together to adsorb wet paper sheets through the roller's suction holes. Simultaneously, a stepper motor drives the rotating outer shell to rotate at a uniform speed. The adsorbed moisture and residue are introduced into a high-pressure moisture and residue recovery chamber through a moisture and residue suction pipe, and then recovered through a moisture and residue outflow pipe at the bottom of the high-pressure moisture and residue recovery chamber, flowing into the next process. Vacuum instruments allow real-time monitoring of internal pressure changes. When pipe blockage occurs, a pressure relief valve promptly releases pressure, ensuring the safety of equipment and personnel. Ultimately, this achieves efficient operation of the device while effectively recovering residue and preparing for subsequent reuse, while also ensuring the safety of equipment and personnel.

[0025] Specifically, during use, the vacuum box 1 and the built-in vacuum box 3 work together to adsorb the wet paper sheet through the suction hole 10 of the roller. At the same time, the stepper motor 4 drives the rotating outer shell 2 to rotate at a uniform speed. The adsorbed water and residue are introduced into the high-pressure water and residue recovery chamber 8 through the water and residue suction pipe 7, and then recovered through the water and residue outflow pipe 9 at the lower end of the high-pressure water and residue recovery chamber 8, flowing into the next process.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The vacuum chamber 1 has a vacuum instrument mounting hole 14 inside. The inner surface of the vacuum instrument mounting hole 14 is tightly fitted with an anti-corrosion and anti-collision ring 15. The inner surface of the anti-corrosion and anti-collision ring 15 is tightly fitted with a vacuum instrument 16.

When a blockage occurs in the pipeline, the pressure relief valve 13 can release the pressure in time to ensure the safety of the equipment and personnel. Ultimately, the device can operate efficiently, effectively recover residues and prepare for subsequent reuse, and also ensure the safety of the equipment and personnel.

[0028] Working principle: During use, the vacuum chamber 1 and the built-in vacuum chamber 3 work together to adsorb wet paper sheets through the suction holes 10 of the roller. At the same time, the stepper motor 4 drives the rotating outer shell 2 to rotate at a constant speed. The adsorbed moisture and residue are introduced into the high-pressure moisture and residue recovery chamber 8 through the moisture and residue suction pipe 7, and then recovered through the moisture and residue outflow pipe 9 at the lower end of the high-pressure moisture and residue recovery chamber 8, flowing into the next process. The vacuum instrument 16 can monitor the changes in the internal air pressure of the device in real time. When the pipe is blocked, the pressure relief valve 13 can release the pressure in time to ensure the safety of the equipment and personnel. In the end, the device can operate efficiently, effectively recover residue and prepare for subsequent reuse, and also ensure the safety of the equipment and personnel.
