Description

Technical Field

[0001] This utility model relates to a drying equipment for a shoe manufacturing production line, belonging to the technical field of drying equipment. Background Technology

[0002] Drying is a crucial step in shoe manufacturing. After bonding, gluing, or other wet processing steps, shoes may retain some moisture or solvents. Drying effectively removes this moisture, ensuring the quality of subsequent processing. Furthermore, during the bonding of the upper and sole, the adhesive requires time and temperature to fully cure. The drying process provides appropriate heat, accelerating the curing of the adhesive and improving the bond strength. To address this, various drying devices have been developed within the industry. For example, Chinese utility model patent CN204861501U discloses a shoe drying machine, specifically including a cabinet with hinged doors. The cabinet contains a hollow cylinder with air outlets a on its top and sides. These outlets a are through holes. The air outlet is fixedly connected to several shoe racks, which are Y-shaped and inclined relative to the horizontal plane. Each shoe rack has several air outlets b, which are through holes. The shoe racks are evenly arranged on the sides of the air outlet. The bottom of the air outlet is connected to an air inlet pipe, which is connected to a hot air blower. The top of the cabinet has an air outlet, and the bottom of the cabinet has support legs. When shoes are manually hung on the shoe rack or taken out one by one, the hot air inside the machine escapes and lowers the temperature of the drying area. The machine needs to be reheated to achieve effective drying, resulting in slow drying efficiency and high energy consumption. Utility Model Content
