Hot air nozzle for drying

Abstract

The invention discloses a hot air nozzle for drying. The hot air nozzle for drying comprises a housing, wherein an air inlet is formed in the front end of the housing, and an air outlet is formed in the rear end of the housing; an inner chamber of the housing is divided into a front chamber and a rear chamber through a longitudinal air distributing plate; the front chamber communicates with the air inlet, and the rear chamber communicates with the air outlet; a ventilating hole through which the front chamber communicates with the rear chamber is formed in the air distributing plate. According to the hot air nozzle for drying, the air distributing plate is arranged in the inner chamber of the housing, and hot air entering the front chamber through the air inlet is stopped by the air distributing plate and then fills the whole front chamber, so that the uniformity of the hot air can be improved; then the hot air enters the rear chamber through the ventilating hole, the speed of the hot air is increased, and finally the hot air is sprayed out through the air outlet. Therefore, the uniformity and stability of the hot air can be effectively ensured, and the drying efficiency and the drying effect can be improved.

Description

technical field [0001] The invention relates to a nozzle, in particular to a hot air nozzle of film coating and drying equipment. Background technique [0002] The nozzle is an important part of the film coating and drying equipment. After the printing materials such as paper and cloth are coated, sizing, and water-coated, they need to be dried with the hot air blown out from the nozzle. The nozzle sprays out a stable and balanced hot air. In order to ensure the smooth movement and uniform drying of the coated film when it is dry. The air inlet and the air outlet of the existing hot air nozzles are directly connected, and the speed stability and uniformity of the ejected hot air are poor, so that the strength and temperature of the hot air received by the printing materials are different, and the drying effect is uneven, which will reduce the drying effect. The drying efficiency is also easy to deform the printed material. Contents of the invention [0003] In order to s...
