Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal leveling equipment, specifically a rapid centrifugal leveling machine for coating. Background Technology

[0002] The rapid centrifugal leveling machine for coating is a specialized device that uses centrifugal force to accelerate the leveling of coating materials on the surface of a workpiece, improving the smoothness and uniformity of the coating. It is mainly used in industrial fields that require high-precision coating treatment. By quickly eliminating defects such as bubbles, pinholes, and orange peel on the coating surface, it improves the coating quality.

[0003] The core of the equipment is to utilize the effect of centrifugal force on the coating material. When the workpiece (such as plate, disc, lens, etc.) is placed on the rotating worktable of the equipment, the equipment drives the workpiece to rotate at high speed through the drive system (the speed is usually adjustable, from hundreds to thousands of revolutions per minute). Under the action of centrifugal force, the coating material (such as paint, adhesive, functional film material, etc.) spreads and flattens rapidly along the surface of the workpiece.

[0004] Existing rapid centrifugal leveling equipment for coating often requires separate operations or two sets of equipment to handle single-sided and double-sided spraying when processing discs or lens frames. This separate processing method not only reduces the efficiency of workpiece coating, but also increases the purchase and use costs of the equipment when configuring two sets of equipment. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a rapid centrifugal leveling machine for coating, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid centrifugal leveling machine for coating, comprising a device housing, a rotating drum disposed on the inner wall of the device housing, and a first placement frame disposed on the outer wall of the rotating drum, a support assembly for placing workpieces disposed on the inner wall of the rotating drum, the support assembly comprising a limiting plate, a second placement frame and contact blocks, the second placement frame disposed at the bottom of the limiting plate, and multiple sets of contact blocks mounted on the outer wall of the second placement frame, and a protrusion disposed at the bottom of the second placement frame, and a filter assembly disposed at the bottom of the device housing.

[0007] By adopting the above technical solution, and by setting the first placement frame and support assembly on the outer and inner walls of the rotating drum respectively, the workpiece can be processed simultaneously on one side and both sides, which effectively improves the work efficiency. Especially for workpieces with curved surfaces that require single-sided coating, the workpiece is placed on the outer wall of the first placement frame. Under the force of the rotating drum, the workpiece on the outer wall of the support assembly is coated on both sides, while the workpiece on the outer wall of the first placement frame is coated on one side, which improves the work efficiency of the equipment. By setting the limiting groove, the groove limits the bottom of the first placement frame, and the limiting groove engages with the protrusion, so that the first placement frame and support assembly are movably connected to the equipment, which facilitates the replacement and cleaning of the placement frame and effectively improves the practicality of the equipment.
