Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0018] Aiming at the shortcomings of the traditional process, we invented two atomizing sizing nozzles, allowing the glue to atomize in the nozzle and enter the fiber spray pipe in the form of mist. The glue can be evenly coated on the surface of the fiber, thereby reducing glue consumption and removing Glue effect.

[0019] as attached figure 1 Shown is a schematic diagram of the principle of the two-time atomization sizing nozzle, a sizing nozzle, including a glue inlet 2 and a glue outlet, the glue outlet is connected to the fiber spray pipe 1, and the first section of the pipeline in the sizing nozzle is connected to the glue outlet. The inlet pipe 6 connected to the glue inlet 2, the side wall of the inlet pipe 6 is also connected to the compressed air inlet 3, the diameter of the inlet pipe 6 is smaller than the diameter of the glue inlet 2,...

Abstract

The invention relates to a nozzle, in particular to a glue applying nozzle during production of artificial boards. The glue applying nozzle comprises a glue water inlet and a glue water outlet, wherein the glue water outlet is communicated with a fiber spraying pipe. The glue applying nozzle is characterized in that the side wall of an inlet pipeline communicated with the glue water inlet is also communicated with a compressed air inlet; the diameter of the inlet pipeline is smaller than that of the glue water inlet; a first atomizing chamber is communicated with the inlet pipeline; the diameter of the first atomizing chamber is greater than that of the inlet pipeline; a second atomizing chamber is communicated with the first atomizing chamber; the first atomizing chamber is connected with the second atomizing chamber through a thin pipeline; and the diameter of the second atomizing chamber is greater than that of the thin pipeline and is smaller than that of the first atomizing chamber. According to the glue applying nozzleprovided by the invention, due to the twice atomizing design, the glue water can be fully atomized and dispersed, the obtained glue water particles are smaller and more uniform and can be uniformly coated on the fiber surfaces, the product quality is stable, and the usage amount of the glue water also can be saved.

Description

technical field [0001] The invention relates to a nozzle, in particular to a sizing nozzle in the production of wood-based panels. Background technique [0002] In the production process of medium and high-density fiberboard, the sizing method is mainly carried out in the fiber spraying pipe. The traditional glue sizing method is to use the glue pump to deliver glue to the fiber spraying pipe, so that the glue and fibers can flow at high speed in the fiber spraying pipe. It is sprayed into the fiber discharge pipe through the sizing nozzle, and mixed with the high-speed moving fibers in the fiber discharge pipe to produce turbulent flow during the high-speed advancement to achieve frictional sizing. In actual production, this sizing method is prone to uneven sizing and glue spots, which affects product quality, makes product quality unstable, and consumes a lot of glue. [0003] After the glue is pressurized by the glue pump, it is sprayed into the fiber discharge pipe thro...
