Problems solved by technology

[0004] In view of the above-mentioned problem of uneven sizing when sizing large-scale thin shavings, the present invention has further researched and found that: this is because the shavings are vertically falling when sizing large-scale thin shavings, resulting in too fast a falling speed, which cannot be fully mixed with the glue solution. Contact causes uneven sizing

Abstract

The invention relates to the technical field of large sheet shaving gluing devices and particularly relates to a large sheet shaving gluing and inflaming retarding device. The large sheet shaving gluing and inflaming retarding device comprises a shell, a first conveying device, a second conveying device, a flame retardant spray head, a glue spray head and a centrifugal fan. The shell is of a cylindrical structure with a chamber, a feeding port is formed in the upper portion of the side wall of the shell, and a discharging port is formed in the bottom of the shell. The first conveying device isused for conveying raw materials into the feeding port. The second conveying device is arranged below the discharging port, and the flame retardant spray head and the glue spray head are arranged onthe side wall of the shell and located on the opposite side of the feeding port. The centrifugal fan is arranged on the top wall of the shell and can apply upward stretching force to the interior of the shell. The device can effectively prolong the contact time of atomized glue drops and shaving and improve the flaming retarding and gluing uniformity, so that the device can effectively give a flaming retarding function to shaving boards in the gluing process, and the production procedures of the shaving boards are simplified.

Description

technical field [0001] The invention relates to the technical field of sizing devices for large shavings, in particular to a sizing and flame retardant device for large shavings. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] In Europe and the United States, oriented strand board (OSB) has gradually replaced plywood, fiberboard and other wood-based panels due to its uniform material, high strength, and stable dimensions, and is widely used in construction, decoration, packaging and other fields. In my country, with the rapid development of the particleboard industry in recent years and the commissioning of several oriented strandboard production lines, the ...
