Description

Technical Field

[0001] This utility model relates to the field of sandpaper production technology, specifically to a high-efficiency drying device for sandpaper production. Background Technology

[0002] Sandpaper, also known as abrasive paper, is a material used for grinding. Depending on the abrasive material, there are various types, such as diamond sandpaper, artificial diamond sandpaper, and glass sandpaper. Dry sandpaper is used to polish the surface of wood and bamboo, while water-resistant sandpaper is used to polish the surface of metal or non-metal workpieces in water or oil. The base paper is made entirely from unbleached sulfate wood pulp, making it strong, durable, and fold-resistant with good water resistance. Abrasive materials such as glass sandpaper are bonded to the base paper with adhesives such as resin, and then dried.

[0003] Drying is an essential processing step in the production of sandpaper. However, existing sandpaper drying equipment often simply stacks multiple layers of sandpaper together for drying. The overlapping surfaces of the sandpaper are heated unevenly, requiring a lot of time to dry. Furthermore, replacing the second batch of sandpaper after one batch has been dried consumes a significant amount of time, reducing work efficiency. Utility Model Content

Several equally spaced hollow partitions are provided on the top end face of the base plate between the two baffles.

[0008] By using the above technical solution and the perforated partition, the airflow of the drying rack is improved, which enables the sandpaper to be dried evenly on both sides, and avoids uneven heating of the sandpaper when they are stacked together.

[0009] As a preferred technical solution of this utility model, the outer side of the top end face of the baffle is provided with a fixing plate that can overlap the top end face of the drying box between the two support plates, and the top end face of the fixing plate is provided with a lifting handle.

[0010] By using the above technical solution and the setting of the fixing plate, the gaps in the drying rack installed in the drying box can be sealed, preventing heat loss during the drying process and improving the drying efficiency of sandpaper.

[0011] As a preferred technical solution of this utility model, the baffle is provided with a plurality of convection holes.

[0012] By utilizing the above technical solution and the convection holes, the uniformity of sandpaper drying is further improved.

[0013] As a preferred embodiment of this utility model, the air supply pipe is connected to the air blowing pipe, and a heating box is provided on the air supply pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

The drying rack containing the sandpaper is then inserted into the drying chamber, with the fixing plates on both sides of the rack resting on the top surface of the drying chamber between the beam support plates for fixation. The heating box begins to heat up, and the blower is activated. Air heated by the heating box is then sent into the air duct and ejected, supplying hot air to the drying chamber to dry the sandpaper in the drying rack. This invention, through the design of the drying rack, allows workers to simultaneously place different batches of sandpaper into the drying chamber for drying. Furthermore, once the sandpaper in one drying rack is dried, it can be removed individually, greatly improving usability and avoiding the time-consuming process of replacing one batch of sandpaper with the next, which leads to significant heat loss and greatly improves drying efficiency.
