Air nozzle fastening structure for branch air pipe

Abstract

The invention relates to an air nozzle fastening structure for branch air pipe. The structure comprises air nozzles and air nozzle fasteners, the air nozzle is used for providing uniform hot air for a drying room, an air nozzle plate is fixedly connected at two ends of the air nozzle, an air outlet is fixed at the exit of the air nozzle, flanges are vertically fixed at two ends outside the air outlet, a plurality of air nozzle fasteners are arranged in the lengthwise direction of the air nozzle, the air nozzle fastener has a straight plate, two ends of the straight plate are fitted on the flanges, a folded plate is vertically fixed at two sides of the straight plate and embedded in the air outlet, two ends of the folded plate and the air outlet are in interference fit, and the air nozzle fastener has a crossed unfolding shape. The inventive air nozzle fastening structure is firm, can prevent the air nozzles and air nozzle plates from flanging inwards / outwards under pressure by use of the air nozzle fasteners, and has the folded plate embedded in the air outlet to ensure the air outlet spacing. The air nozzle fastener has simple manufacture, convenient mount and repair, and high production efficiency, the air nozzle fastener plate has small thickness, little material consumption and low cost, and the plurality of air nozzle fasteners and the air nozzle are firmly connected to indirectly reduce air nozzle plate thickness and lower production cost.

Description

technical field [0001] The invention relates to an air nozzle fastening structure for an air distribution pipe. Background technique [0002] The air distribution pipe is a part that provides uniform hot air in the drying room. In order to achieve the effect of blowing out uniform hot air, the air distribution pipe needs to be equipped with multiple rows of air nozzles. The high-temperature gas blown out of the air nozzles will easily cause the deformation of the air nozzles, and the distance between the air outlets of the air nozzles is usually 8-10mm, so the air nozzles should be fixed accurately. And it is often difficult not to deform. [0003] Such as figure 1 As shown, the existing air nozzle of the first type is connected by fixing bolts 4 and fixing nuts 7, and an intermediate nut 6 is connected inside the air outlet, and the intermediate nut 6 ensures the distance between the air outlets. In order to prevent the connection of the fixing bolt 4, the intermediate n...
