Description

Technical Field

[0001] The utility model belongs to the technical field of curing ovens, and in particular relates to a hanging curing oven. Background Art

[0002] Nowadays, most fishing rods are made of carbon fiber. When using carbon fiber for fishing rod production, the shaped carbon fiber rods need to be cured to improve their toughness and strength. This curing process takes place in a curing oven. Because the thickness of the rod sections varies, the molds used for coiling vary. The curing oven is equipped with a hanger for the molds. Currently, a common method is to install multiple rectangular hanger slots on a support plate, into which the molds are hung. However, a specific hanger slot width cannot accommodate molds of varying thicknesses. To address this issue, one approach is to install hanger slots of varying sizes in the curing oven, allowing different molds to be hung in the corresponding areas. Another approach is to replace the hanger slots (support plates) within the curing oven according to the mold to be hung. The first approach can lead to the oven not being fully loaded, resulting in energy waste. The second approach makes replacement difficult and hinders standardized assembly line operations.
