Description

Technical Field

[0001] The invention relates to the technical field of metal plate spraying, in particular to anti-corrosion powder metal plate coating equipment and a production process thereof. Background Art

[0002] Anti-corrosion powder coatings are made of special resins, pigments, fillers, curing agents and other additives, which are mixed in a certain proportion and then prepared through processes such as hot extrusion, crushing and screening. They are storage-stable at room temperature and are subjected to electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dipping (thermoplastic method), and then heated, baked, melted and solidified to form a smooth, bright, permanent coating film, achieving the purpose of decoration and corrosion protection.

[0003] In the prior art, when anti-corrosion powder coating is sprayed on metal plates, it is inconvenient to collect excess coating, resulting in a waste of resources and uneven coating thickness on the surface of the metal plates. When the sprayed metal plates are transported to the drying equipment, the workers lift the metal plates, which can easily cause the coating on the metal plates to be wiped off, resulting in coating defects on the metal plates. Summary of the invention

[0010] A production process for anti-corrosion powder metal plate coating equipment comprises the following steps:

[0011] Step 1: Install the plate, place the metal plate between the two baffles, and the limit column is isolated between the metal plate and the baffle;

[0012] Step 2: Spraying, electrostatically spray anti-corrosion powder coating on the surface of the metal plate. After spraying, lift one side of the connecting plate by holding the handle. At this time, the metal plate is tilted, and the excess paint on the surface of the metal plate slides down to between the baffle and the metal plate, and falls between two adjacent limit columns.

The driving motor drives the toggle plate to stir the airflow inside the drying box to make the hot air temperature uniform. The coating on the surface of the metal plate is heated and cured. The pressure relief valve relieves the pressure inside the drying box to ensure work safety.

[0015] Step 5: Unloading. After the paint on the surface of the metal plate is cured, the piston rod of the electric hydraulic cylinder extends downward to lower the connecting plate. Then, after the screws on the surface of the sleeve are loosened, the piston rod of the electric hydraulic cylinder rises back, and after the connecting plate is pushed away, the metal plate can be removed from the pad. The discharge port can be opened to unload the recycled materials inside the storage rack.

[0018] 2. The anti-corrosion powder metal plate coating equipment proposed by the present invention directly pushes the connecting plate to carry the sprayed metal plate to the bottom of the drying box, and connects it with the piston rod of the electric hydraulic cylinder through the sleeve. The piston rod of the electric hydraulic cylinder is recovered to drive the connecting plate to rise, and the metal plate is lifted to the inside of the drying box for drying treatment, thereby preventing the paint on the surface of the metal plate from being worn out;

[0019] 3. The production process of the anti-corrosion powder metal plate coating equipment proposed by the present invention has a simple operation process, low technical requirements for workers, and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS
