Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically a baking oven for spraying. Background Technology
[0002] In the field of mechanical parts manufacturing, to improve the corrosion resistance, appearance, and wear resistance of parts, it is usually necessary to coat their surfaces with paint, anti-rust coatings, or functional protective layers. These coatings require drying and curing to form a stable adhesion structure. Conventional natural drying methods not only have long drying cycles but are also easily affected by environmental factors such as temperature, humidity, and dust, failing to meet the efficiency requirements and quality standards of mass production of mechanical parts. Therefore, after coating application, specialized baking equipment must be used to dry the parts to quickly achieve coating curing, ensuring parts production efficiency and finished product quality.
[0003] Currently, existing baking equipment generally consists of a hot air blower, a casing, an exhaust vent, and a door. During operation, the hot air blower sends hot air into the casing to bake the parts inside. Water vapor is generated during the baking process and is discharged from the exhaust vent along with the gas, thereby drying the material sprayed on the parts.
[0004] However, the air outlet positions of existing baking devices are relatively fixed, and hot air is generally blown in a directional manner. This method will cause uneven heating of parts. Parts near the air outlet are overheated, and the coating is prone to color difference and cracking. Meanwhile, parts far from the air outlet are underheated, and the drying time will be prolonged. It is difficult to ensure the consistency of coating drying quality of parts in the same batch. In order to address the above problems, we provide a baking oven for spraying to solve the aforementioned problems. Utility Model Content
