2results about How to "Integrity is not compromised" patented technology

This utility model relates to the field of spunlace fabric production technology and discloses a spunlace fabric production line, which includes a sizing screen and a spunlace screen. Corresponding web-forming screens and a first web-forming vacuum suction device are arranged on both sides of the sizing screen. After the fiber web is formed on the sizing screen, the mutual compression between the web-forming screen and the sizing screen smooths the rough surface of the fiber web. The first web-forming vacuum suction device then removes moisture from the fiber web, reducing its moisture content. This reduces the deviation in distance between the fiber web and the hydroentanglement during the first hydroentanglement process, ensuring that the hydroentanglement energy is fully and evenly received by the fiber web, promoting uniform fiber entanglement. Compared to roller compression, this method is gentler. While the web-forming screen is compressing the sizing screen, the moisture is absorbed by the vacuum suction device below, and the negative pressure adsorbs the fiber web, preventing damage to its integrity. This utility model features a simple structure, strong practicality, and good performance.

This invention discloses a vortex water tank with a constant temperature extrusion die, comprising a tank body, end plates fixed to both ends of the tank body, a sealing plate dividing the inner cavity of the tank into a vacuum section and a non-vacuum section, a top cover rotatably connected to the top of the tank body, and a sealing seat disposed in the non-vacuum section. The sealing seat has a through hole for the profile to pass through, and a water seal structure for forming a dynamic water seal is provided in the through hole. It also includes an extension cover, fixedly connected to the side of the sealing seat near the non-vacuum section, with its end rotatably connected to the sealing plate via a rotating shaft. By automatically releasing the sealing plate and opening the channel, the profile head can be smoothly output under the protection of the formed complete water seal. This avoids poor profile head shaping, dimensional fluctuations, and surface defects caused by insufficient vacuum or incomplete water seal establishment, thereby minimizing the waste length during startup and significantly improving material utilization and startup yield.
