Description

Technical Field

[0001] The utility model relates to the technical field of particle board processing, in particular to a device for quickly cooling particle boards after hot pressing. Background Art

[0002] Particleboard is a man-made board material made from wood materials such as small-diameter wood, branches, and wood processing residues, or non-wood materials such as sugarcane bagasse and cotton stalks, mixed with glue and then pressed. It offers advantages such as uniform structure, good workability, strong nail holding power, and good moisture resistance, making it widely used in furniture manufacturing, building decoration, packaging, and other fields. The main process of particleboard production includes material preparation, chipping, flaking, drying, sorting, glue mixing, laying, pre-pressing, hot pressing, unloading, cooling, edge sawing, sanding, inspection, and storage. After hot pressing, particleboard has a high heat content, requiring rapid cooling. However, natural heat dissipation is inefficient and takes up a large amount of space. Therefore, a dedicated cooling device is required to cool the particleboard. Authorization Publication No. CN207901365U discloses a rapid cooling device for particleboard. The device comprises a cooling table, a controller, a chute, a fixed plate, and a stop bolt. The controller is fixedly connected to the lower right side of the cooling table. The chute is located on the left and right sides of the cooling table. The fixed plate is fixedly connected to the upper end of the cooling table. The stop bolts are fixedly connected to the left and right sides of the fixed plate. The chute is internally provided with a pulley, a movable plate, a connecting plate, a slide rail, a blower, a connecting pipe, and a wind hood. The pulley is movably connected to the chute. The device has the advantages of simple structure, easy operation, low noise, and fast cooling speed. The design of the pulley and slide rail can effectively realize the automatic adjustment of the blower's position, accelerating the cooling speed of the particleboard and saving the cooling time of the particleboard. The device can also simultaneously adjust the position of the blower in both the horizontal and vertical directions.

[0003] The above-mentioned existing technical solution has the following defects: the inventor found that the wind blown by the hair dryer of this technical solution can only blow on the upper surface of the particle board, while the lower surface of the particle board cannot be blown by the wind. This cooling method reduces the cooling effect and cooling efficiency. Utility Model Content
