High-precision scraper paste control device

Abstract

The invention relates to a high-precision scraper paste control device. The device comprises a rack, an applying roller and a paste tank for containing paste, wherein the applying roller is transversely arranged on the rack and is in rotating fit with the rack, the paste tank is arranged below the applying roller, the applying roller part is located in the paste tank, a paste scraper is arranged besides the applying roller, extends in the axial direction of the applying roller and is adjustably arranged on the rack, edges of the paste scraper get close to or contact with the periphery of the applying roller through adjustment of the position of the paste scraper, so that redundant paste on the periphery of the applying roller is scraped away precisely, and high-precision paste control is realized. The device adopts the paste scraper to scrape away the redundant paste on the periphery of the applying roller, and the straightness of the paste scraper is easy to guarantee, so that the distance between the paste scraper and the periphery of the applying roller is equal, the margin of the paste on the surface of the applying roller can be controlled accurately, high-precision paste control can be realized at the lower cost, paste waste is avoided, the quality of corrugated paper can be improved, and the environment protection requirement for energy conservation and emission reduction is met.

Description

technical field [0001] The invention relates to corrugated paper production equipment, in particular to a high-precision scraper pulp control device mainly used in corrugating machines and pasting machines. Background technique [0002] The existing corrugated paper production equipment mainly includes a corrugator and a paster machine, which include a sizing roller and a pulp control roller. The surface of the sizing roller has a pattern, and the sizing roller is partially immersed in the paste. By rotating the sizing roller, the paste can be attached to the mesh. surface, and then by adjusting the distance between the pulp control roller and the sizing roller, the excess paste on the anilox surface can be squeezed away, and finally, the sizing roller is in contact with or close to the core paper of the corrugated paper to spread the remaining paste in the sizing roller on the The surface of the core paper, so that the core paper can be bonded to the face paper.

AI Technical Summary

Problems solved by technology

However, because the current sizing roller controls the pulp through the pulp control roller, the pulp control roller is limited by the processing accuracy, and the straightness of the pulp control roller is affected, and because the pulp control roller has a high rigidity, the pulp control roller cannot be too close Otherwise, the part of the size control roller will touch the sizing roller, which will cause the anilox surface of the sizing roller to be worn or even scrapped

In addition, since the size control roller cannot be too close to the surface of the sizing roller, the excess paste on the surface of the sizing roller cannot be accurately squeezed out, resulting in too much paste on the surface of the sizing roller. When the core paper is coated with paste, it will cause too much paste on the core paper, and the dried paste will block the corrugated pits. On the one hand, the paste is wasted, and on the other hand, the characteristics of the corrugated paper will be affected.
