Problems solved by technology
[0009] At present, the curing equipment of ordinary thermosetting coatings is all in the oven. Although it has the advantages of energy saving and other advantages, it also has the disadvantages of being far away from the heat source, slow heating speed, long cooling process, and easy cold air during cooling, which will cause the curing plate to deform and become warped.

The invention discloses a heating curing device of a thermosetting coating. The heating curing device comprises a temperature controller, a heating chamber, a heating belt, a heating belt protective cover, a convection fan and a heating curing trolley, wherein the heating chamber is provided with furnace doors; the furnace doors are arranged on the left and right sides of the heating chamber; the heating belt and the heating belt protective cover are arranged on the chamber wall of the heating chamber; and the heating curing trolley comprises a trolley bottom plate, travelling wheels, trolley heating belts, automatic lifting guard boards, baffle plates and driving motors. According to the heating curing device, through the high convective circulation of high temperature airflow, the thermal energy utilization rate is high, and the heat exchange effect is good; the automatic lifting guard boards perform heat-insulating protection on the driving motors; and when the automatic lifting guard boards rise, the phenomena that a heated coating plate deforms or the coating peels off and cracks, and the like due to the hot air convection are avoided, and the heat dissipation of the driving motors is quickened.
Description
technical field [0001] The invention relates to a paint curing device, in particular to a heat curing device for thermosetting paint. Background technique [0002] Thermosetting powder coatings are made of powder coating resins with small molecular weight. Under the condition of heating and baking, chemical crosslinking reaction occurs with curing agent to obtain a coating film with good performance. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, Composed of fillers and additives, pre-mixed, melt-extruded, crushed, graded and sieved, the main types of thermosetting powders on the market are pure epoxy, epoxy-polyester, pure polyester, acrylic acid, polyurethane, etc. , Thermosetting powder coatings have low melt viscosity, good leveling, non-melting coating film after cross-linking, very suitable for anti-corrosion or decorative workpiece surfaces with high performance and technical requirements, and are the mainstream products i...
