Online moisturizing coating device

Abstract

The invention relates to an online moisture-preserving coating device. The online moisture-preserving coating device comprises a coating roll and a pressure roll arranged above the coating roll, wherein a liquid feeding device is arranged below the coating roll and comprises a rubber liquid groove and two rubber rolls, the two rubber rolls are respectively arranged on two sides of the coating roll in parallel with the coating roll, the two rubber rolls and the coating roll are distributed in an rectangular manner, the rubber roll on a cloth feeding side is a liquid feeding rubber roll, and the rubber roll on a cloth discharging side is a support rubber roll; liquid is fed through the friction rolling of the roll surfaces of the liquid feeding rubber roll and the support rubber roll and the roll surface of the coating roll, a grid entraining rubber liquid is arranged on the roll surface of the coating roll, a plurality of reflux grooves are formed in the roll surface of the support rubber roll side by side along the axis of a roll body, and the rotating speeds of the two rubber rolls are obviously lower than the rotating speed of the coating roll. According to the online moisture-preserving coating device, the coating roll, the pressure roll and the two rubber rolls form a triangular structure, the three rolls are located pressure-supported balanced positions, the coating roll is not deformed, and hard friction among the rolls is avoided, so that the service life of the device is prolonged, the liquid is uniformly fed, and the moisture-preserving property is stable.

Description

technical field [0001] The invention relates to a slitting and winding machine, in particular to an online moisturizing coating device. Background technique [0002] The existing slitting and winding machine produces high-end and high-quality sanitary paper after the toilet paper base paper is coated and moisturized. The existing principle of coating and moisturizing is: toilet paper base paper passes between the main roll and the pressure roll, and after the main roll is turned out of the liquid, the liquid on the roll surface is scraped off by the contact of the scraper with the roll surface. There are following two problems in this coating moisturizing mode: [0003] First, when the scraper is scraped against the roller surface, it is easy to trap small debris such as paper scraps at the angle between the scraper and the roller surface, which will lift up the scraper at this position, and the liquid will leak out, forming strips of wet liquid line, it will cause the pro...

AI Technical Summary

Problems solved by technology

[0003] First, when the scraper is scraped against the roller surface, it is easy to trap small debris such as paper scraps at the angle between the scraper and the roller surface, which will lift up the scraper at this position, and the liquid will leak out, forming strips of wet liquid line, it will cause the product to be unqualified, and it will damage the scraper and the main roller. It must be shut down for cleaning, which will cause a lot of waste, and the production speed cannot be improved, which greatly limits the production efficiency and quality;

[0004] Second, the scraper and the roller body are relatively scraped and worn. After a period of use, the scraper wears out. This is one. The second is that the surface of the roller surface is also worn. The liquid level on the toilet paper is affected by the quality, either locally more or less, which greatly affects the quality of the produced products

[0005] Therefore, during the coating and moisturizing process, the moisture retention of toilet paper base paper will be directly affected by the blade alignment, parallelism, pressure and the negative effect of the roller body after being pressed, that is to say, the stability is difficult to grasp.
