Description

Technical Field

[0001] This utility model relates to the field of powder coating curing and baking technology, and in particular to a segmented low-temperature curing and baking device for powder coatings. Background Technology

[0002] Powder coatings, as an environmentally friendly and high-performance coating product, are widely used in industrial and civilian fields. The curing process of powder coatings is a key factor determining the quality and performance of the coating. Through curing, powder coating particles fuse and cross-link to form a continuous, dense coating with excellent physicochemical properties, giving the workpiece excellent protective and decorative functions. The curing process of powder coatings is a complex physicochemical change process that plays a decisive role in the performance of the final coating. During the curing process, the resin, curing agent, and other components in the powder coating undergo cross-linking reactions to form a three-dimensional network structure, giving the coating the required hardness, adhesion, flexibility, corrosion resistance, and other properties. If the curing is insufficient or uneven, the coating may suffer from insufficient hardness, easy peeling, and poor chemical resistance, seriously affecting the quality and service life of the product.

[0003] Traditional powder coating curing and baking equipment typically uses a single temperature zone for baking. However, the temperature requirements for powder coatings vary at different stages of the curing process. In the initial stage, excessively high temperatures may cause premature film formation on the powder coating surface, hindering further cross-linking reactions and affecting the overall performance of the coating. Conversely, in the later stages of curing, if the temperature is too low, the cross-linking reaction may not proceed sufficiently, leading to insufficient coating hardness and poor adhesion. Baking in a single temperature zone is insufficient to meet the complex temperature requirements of powder coatings throughout the curing process, easily resulting in uneven curing and affecting product quality.

[0015] (III) Beneficial Effects

[0016] This utility model provides a segmented low-temperature curing and baking equipment for powder coatings, which has the following features:

[0017] Beneficial effects:

[0018] 1. This segmented low-temperature curing and baking equipment for powder coatings, through the setting of a separation mechanism and a heating mechanism, allows for precise control of the powder coating curing and baking temperature at each stage, improving product quality. First, the placement box is moved to the entrance of the drying chamber, and the central hydraulic rod is activated to close the separation plate at its end. At this time, a surface-mounted thermometer monitors the internal temperature of the drying chamber in real time. Then, the surface temperature controller is activated, which controls the heating meshes installed on both sides of the inner wall of the drying chamber to generate heat. The main function is to slowly heat the workpiece to a certain temperature, initially softening the powder coating and preparing it for the subsequent cross-linking reaction. This process continues, controlling the appropriate temperature in the middle of the drying chamber to complete the cross-linking reaction, and finally completing the curing stage at the outlet of the drying chamber. This achieves precise control of the powder coating curing and baking temperature at each stage.

[0019] 2. This segmented low-temperature curing baking equipment for powder coatings, through the setting of the clamping mechanism, allows the workpiece to be baked to be placed inside the placement box during use. Then, the placement box is placed on the placement plate, and the threaded rods on both sides of the placement plate are rotated, causing the threaded rods to rotate on the end shaft. This drives the two clamping plates on one side of the shaft to move relative to each other, thereby firmly fixing the middle placement box on the placement plate. This prevents the placement box from shifting, shaking, or even falling off during the baking process due to vibrations generated by the equipment operation or other external forces, ensuring that the workpiece remains in a stable position throughout the entire baking process.
