Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber tube production curing furnaces, and particularly relates to a curing furnace with a rapid temperature adjustment inside the furnace. Background Art

[0002] The carbon fiber tube, also known as the carbon fiber tube and carbon tube, is made by pre-impregnating carbon fiber materials into styrene and polyester resin and then heating and curing by pultrusion. It is widely used in mechanical equipment such as rollers for industrial machinery, aerospace, medical, and PC equipment rotating shafts. In the production of carbon fiber tubes, after the winding is completed, the carbon fiber mold roller needs to be placed in the curing furnace for curing operations to cure the carbon fiber layer into a tubular structure, facilitating subsequent demolding from the carbon fiber mold roller. There may be differences in temperature in different areas inside the curing furnace. Most common curing furnaces have a fixed structure for curing the carbon fiber mold roller. Several groups of carbon fiber mold rollers are fixedly arranged at different positions inside the curing furnace, which will lead to differences in the curing of carbon fiber mold rollers in different areas, resulting in inconsistent quality of the final carbon fiber tube products. If manufacturers want to improve the quality, they need to spend energy and cost to balance and control the temperature in different areas inside the curing furnace.

[0003] In summary, there are some problems in the curing of carbon fiber mold rollers with a fixed structure inside the curing furnace. Therefore, it is hoped to propose a new structure to solve the above technical problems. Content of the Utility Model
