A paper-making drying device with an air hood

Abstract

The invention discloses a papermaking drying device with an air hood, which comprises a casing and an exhaust pipe. A drying chamber is opened inside the casing, and a gas hood chamber is opened on the top of the casing close to the drying chamber, wherein the The exhaust pipe is located on the top of the shell, and the exhaust pipe communicates with the gas hood room. The first transmission roller is rotatably connected above the drying chamber, and is rotatably connected below the first transmission roller near the drying chamber. There is a second transmission roller, a feed inlet is opened in the middle of the shorter side of the housing, and a discharge outlet is provided on the side of the housing away from the feed inlet, and the first transmission roller is fixed on the outside of the housing. first gear. The papermaking drying device with an air hood is provided with a first transmission roller and a second transmission roller, and the paper is simultaneously driven by the first transmission roller and the second transmission roller, so that the paper passes through the first transmission roller and the second transmission roller The second transmission roller squeezes the paper to prevent the paper from wrinkling.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a papermaking drying device with an air hood. Background technique [0002] Paper is made of plant fibers and can be folded arbitrarily for writing. Paper is the carrier of writing and printing. It can also be used for packaging, hygiene and other purposes. In the papermaking process, the paper needs to be dried and used Paper drying equipment. [0003] Although there are many types and quantities of the current papermaking drying devices with gas hoods, there are still certain problems in the existing papermaking drying devices with gas hoods, which brings certain inconvenience to the use of the papermaking drying devices with gas hoods. [0004] When the existing papermaking drying device with an air hood is in use, the paper is dried while being driven by the transmission roller, and then squeezed to avoid wrinkles of the paper. However, during the drying process, the pap...

Problems solved by technology

[0005] The purpose of the present invention is to provide a papermaking drying device with an air hood to solve the problem that the current papermaking drying device with an air hood proposed by the above-mentioned background technology is used to dry the paper while being driven by a transmission roller. Squeeze to avoid paper wrinkles, but during the drying process, the paper has been deformed, and extrusion after drying will easily cause paper wrinkles, and it is inconvenient to clean the impurities on the surface of the transmission roller, which will cause the adhesion of the transmission roller during use. Impurities, which will affect the paper later, reduce the production quality of the paper, and make it inconvenient to use
