Technical Field
[0001] This utility model relates to the field of sandpaper production and processing technology, specifically to an abrasive coating device for sandpaper production. Background Technology
[0002] In the traditional sandpaper production process, the coating of abrasives mostly relies on manual operation, which is inefficient and results in poor coating uniformity. In recent years, with the development of automation technology, the degree of automation in sandpaper production has gradually increased, thus giving rise to corresponding abrasive coating equipment to replace manual coating operations on sandpaper.
[0003] A sandpaper coating and drying device, as described in reference announcement number CN215784460U, includes a material rack with paper rolls to be processed on it. A coating device is located next to the rack, and a slurry spreading device is located next to the coating device. The slurry spreading device is connected to a drying chamber, and a winding device is located next to the drying chamber. This device combines the coating and drying processes in sandpaper production, greatly improving efficiency. It also produces uniform sandpaper coating, short drying time, and good drying results. However, while this device is generally applicable, it is not suitable for coating sandpaper in a confined space. This makes the sandpaper susceptible to contact with external dust and other particles during coating, leading to corrosion and affecting the coating effect, which often troubles users.
