Drying box with layered structure for abrasive paper production

Abstract

The invention discloses a drying box with a layered structure for abrasive paper production, and relates to the technical field of abrasive paper production. The drying box comprises a box body, abrasive paper containing discs and filtering mechanisms, wherein universal wheels are arranged at the four corners of the lower end of the outer portion of the box body, movable push rods are fixed on the two sides of the outer portion of the box body, and a heat preservation interlayer is arranged on the inner side of the box body. According to the drying box, through a vertically-distributed connecting rotating shaft and the box body, the accuracy of the position between the connecting rotating shaft and the box body can be guaranteed, the arranged driving motor drives the connecting rotating shaft to enable the abrasive paper containing discs to rotate, and therefore the temperature uniformity of abrasive paper in the drying process can be guaranteed, and the occurrence of cracking of the abrasive paper due to uneven heating in the drying process is avoided; meanwhile, each abrasive paper containing disc is arranged to be in a sparse hole shape, the circulation rate of hot air is effectively increased, and therefore the drying efficiency of the abrasive paper is improved; and the abrasive paper containing discs are matched with limiting stop blocks arranged at the edges of the abrasive paper containing discs, so the stability of the abrasive paper in the rotating process of the abrasive paper containing discs can be ensured.

Description

technical field [0001] The invention relates to the technical field of sandpaper production, in particular to a drying box with a layered structure for sandpaper production. Background technique [0002] Sandpaper, commonly known as sandpaper, is a material for grinding. It is used to grind the surface of metal and wood to make it smooth. It is usually made of various abrasive grains glued on the base paper. According to different abrasive materials, there are emery paper, Artificial corundum sandpaper, glass sandpaper, etc., dry sandpaper (wood sandpaper) is used to polish the surface of wood and bamboo, water-resistant sandpaper (water sandpaper) is used to polish the surface of metal or non-metal workpieces in water or oil, all base paper Made from unbleached kraft wood pulp, the paper is tough, wear-resistant and fold-resistant, and has good water resistance. Abrasive materials such as glass sand are adhered to the base paper with adhesives such as gum and dried. [000...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a drying box with a layered structure for sandpaper production, to solve the problem that the sandpaper production drying box proposed in the above background technology does not have a layered structure, so that the sandpaper drying efficiency is low and the drying effect is low. Poor, at the same time, there is no gas filtering structure, so that the dried gas is directly discharged and pollutes the air
