Description

Technical Field

[0001] This utility model belongs to the field of vacuum roller dewatering technology, specifically relating to a vacuum roller dewatering device. Background Technology

[0002] In the paper production process, the vacuum couch roll is a key piece of equipment, mainly used to adsorb and stabilize the paper during paper forming and transport. Its working principle is to use vacuum adsorption force to tightly adhere the paper to the couch roll surface, preventing the paper from shifting, wrinkling, or breaking during high-speed transport, thereby ensuring the continuity and quality of paper production.

[0003] In the paper production process, the transfer of wet pulp is a crucial step. The specific operation involves placing the wet paper sheets onto a felt, which then transfers the wet paper sheets between multiple rollers. During this process, the felt absorbs the moisture from the wet paper sheets, thus performing an initial dehydration function.

[0004] Existing dewatering methods can only remove moisture from the surface of the felt, but cannot remove moisture from the deeper layers of the felt. As a result, the moisture from the deeper layers of the felt is carried to the next process along with the wet paper, affecting the dewatering effect of the wet paper and the quality of the paper.

A telescopic assembly 5 is installed on the top of the truss 1. A scraping assembly 6 is placed between the bobbin body 4 and the truss 1. The moving end of the telescopic assembly 5 is connected to the scraping assembly 6. The telescopic assembly 5 is used to adjust the positional relationship between the scraping assembly 6 and the outer wall of the bobbin body 4, so that a part of the scraping assembly 6 contacts the outer wall surface of the bobbin body 4. By adjusting the distance between the scraping assembly 6 and the bobbin body 4 through the telescopic assembly 5, the scraper in the scraping assembly 6 contacts the fabric surface, which can deeply remove water from the fabric, improve the water removal effect of the fabric on the wet wipes, reduce the moisture content in the wet wipes, and improve the quality of the product.

[0020] In a further embodiment, the telescopic assembly 5 includes a mounting plate 51, which is mounted on the top of the truss 1.
