[0002] Hot melt adhesive is a common adhesive that usually exists in solid form in glue sticks or strips. When in use, it is heated to liquid form by a hot melt glue gun and used to bond various materials such as wood, plastic, metal, cloth, etc. Hot melt adhesive particles are a form of hot melt adhesive. During the production and processing of hot melt adhesive, the hot melt adhesive particles need to be filtered in advance to remove impurities from the hot melt adhesive particles and prevent them from being mixed in the production and processing steps, thereby improving the quality of subsequent hot melt adhesive processed products.

[0003] However, the filtering size of the filtering part of the existing filtering device is usually fixed, which limits its filtering range. Replacing hot melt adhesive particles of different sizes also requires replacing the filtering structure, which affects the filtering of the hot melt adhesive particles. In view of this, we propose a hot melt adhesive filtering device. Utility Model Content
