Description

Technical Field

[0001] The utility model relates to the technical field of single-sided machines, in particular to an air suction device for a single-sided machine. Background Art

[0002] The single-facer is one of the important equipment in the corrugated cardboard production line. The quality of corrugated cardboard molding is closely related to the correct use and maintenance of the single-facer. The mechanical equipment for producing corrugated core paper by the single-facer is known as the heart of the "corrugated cardboard production line" in the corrugated packaging industry. Most of the suction devices in the single-facer need to filter the air. After searching, the Chinese patent with publication number CN215473481U discloses a new type of vacuum adsorption device for single-facer. It solves the problem that most of the ordinary single-facer vacuum adsorption devices in the prior art are fixed structures and are inconvenient to maintain and disassemble during production and use through the mounting seat. The existing technology solves this problem through the liquid blocking plate and the air filter element. In the operation, most of the common single-sided machine vacuum adsorption devices do not have air filters, and the problem of easy damage to the fan during use is solved by using rollers and friction knives. The common single-sided machine vacuum adsorption devices in the prior art mostly directly brush glue on the corrugated core paper, which is prone to loose adhesion and degumming. However, as the use time increases, the air filter element will filter out more and more substances and adhere to the air filter element, which will hinder the air passage rate and cause the suction capacity to become lower and lower. For this reason, a suction device for the single-sided machine is designed, which is convenient for eliminating moisture and cleaning the filter element at the same time, ensuring stable suction force, and convenient for cleaning out the cleaned impurities.
