Pretreatment device used before paint coating spraying

Abstract

The utility model provides a pretreatment device used before paint coating spraying. A metal plate to be machined is extruded and fixed through two fixing mechanisms. The compression spring buffers the impact force between the grinding wheel and the to-be-machined metal plate, and the grinding wheel is prevented from exerting too large pressure on the to-be-machined metal plate. The first sliding column slides along the first sliding hole, and the driving plate and the sliding connecting plate get close to each other to extrude the compression spring. When a movable plate and a sliding connecting plate get close to each other, a driving plate makes contact with a pressure sensor, and when the pressure sensor senses pressure, a control mechanism controls an XYZ moving platform to stop driving the driving plate to continue to move downwards, so that the situation that a polishing wheel exerts too large pressure on a to-be-machined metal plate is avoided; and the pressure applied to the to-be-machined metal plate by the polishing wheel is controlled to be consistent, so that the to-be-machined metal plate is uniformly polished by the pretreatment device before the paint coating is sprayed. The rotating motor drives the grinding wheel to rotate so as to grind the metal plate to be machined.

[0001] This utility model relates to the field of metal plate surface treatment, and in particular to a pretreatment device for paint coating before spraying. Background Technology

[0002] Metal decorative panels are made from materials such as aluminum, copper, stainless steel, and aluminum alloy. Essentially, they are also called metal veneer panels, referring to a novel interior decoration material made of metal as the surface material. They are decorative layers formed on wall surfaces through processes such as tiling or structural connection of metal plates or blocks. These decorative layers directly enhance the building's aesthetic appeal, fully utilizing natural or artificial materials to express the designer's style, and providing good concealment and protection for the wall surface. To improve the decorative properties and corrosion resistance of metal decorative panels, paint is generally applied to their surface. However, to improve the adhesion and stability of the paint coating, the metal decorative panels need to be sanded before painting.

[0003] However, traditional metal plate surface treatment equipment, such as the technical solution protected by the patent application number CN202111237122.9, entitled "A Grinding Device for Metal Plate Processing", makes it difficult to control the uniformity of grinding during the grinding process of metal decorative panels.

[0010] Two fixing mechanisms are symmetrically arranged on both sides of the support platform; each fixing mechanism includes a rotating handle, a threaded rod, a rotating plate, an extrusion plate, and a soft protective pad; the rotating handle is connected to one end of the threaded rod, and the end of the threaded rod away from the rotating handle is connected to the rotating plate; the extrusion plate is received in the fixing groove; a U-shaped rotating groove is formed in the middle area of ​​the extrusion plate, the U-shaped rotating groove is adapted to the rotating plate, the rotating plate is received in the U-shaped rotating groove and rotatably connected to the extrusion plate; the soft protective pad is connected to the side of the extrusion plate facing away from the threaded rod; the threaded rod is adapted to the threaded hole, the threaded rod is inserted into the threaded hole and screwed to the support platform;

[0011] The XYZ mobile platform, the two pressure sensors, and the rotating motor are all electrically connected to the control mechanism.

[0012] In one embodiment, the soft protective pad is a soft rubber pad.

[0013] In one embodiment, the soft protective pad is a soft silicone pad.

[0014] In one embodiment, the soft protective pad is a soft plastic pad.

[0020] In one embodiment, the limiting plate is a circular plate structure.

[0021] In the aforementioned pretreatment device before paint coating, the metal plate to be processed is placed in a fixed groove and fixed by two fixing mechanisms. Specifically, rotating the handle rotates the threaded rod, which drives the pressing plate through the rotating plate to press and fix the metal plate, ensuring that the soft protective pad comes into contact with the metal plate. The XYZ moving platform, through the drive plate, two buffer components, sliding connecting plate, and rotating motor, drives the grinding wheel to press against the metal plate. The compression spring buffers the impact force between the grinding wheel and the metal plate, preventing the grinding wheel from applying excessive pressure to the metal plate. During this process, the first sliding column slides along the first sliding hole, and the drive plate and sliding connecting plate move closer to each other, pressing against the compression spring. When the moving plate and the sliding connecting plate approach each other, the drive plate contacts the pressure sensor. When the pressure sensor senses pressure, the control mechanism controls the XYZ moving platform to stop driving the drive plate to continue moving downwards. This avoids applying excessive pressure to the metal plate to be processed by the grinding wheel and ensures that the pressure applied by the grinding wheel to the metal plate is consistent, thereby guaranteeing that the pretreatment device before paint coating spraying can uniformly grind the metal plate to be processed. The rotating motor drives the grinding wheel to rotate to grind the metal plate to be processed. The above-mentioned pretreatment device before paint coating spraying can uniformly grind metal decorative panels. Attached Figure Description

[0037] To effectively absorb dust generated during the sanding process, in one embodiment, the pretreatment device 10 before paint coating spraying further includes two dust collection mechanisms 600.

[0038] During operation, the pretreatment device 10 before paint coating spraying places the metal plate to be processed into the fixing groove 101, and the metal plate to be processed is pressed and fixed by two fixing mechanisms 400. Specifically, the threaded rod 420 is rotated by rotating the handle 410. During the rotation of the threaded rod 420, the pressing plate 440 is driven by the rotating plate 430 to press and fix the metal plate to be processed, so that the soft protective pad 450 abuts against the metal plate to be processed. The XYZ moving platform 310 drives the grinding wheel 362 to press against the metal plate to be processed through the drive plate 320, two buffer components 340, sliding connecting plate 330, and rotating motor 361. The compression spring 341 buffers the impact force between the grinding wheel 362 and the metal plate to be processed, avoiding excessive pressure from the grinding wheel 362 on the metal plate to be processed. In this process, the first sliding column 342 slides along the first sliding hole 301, and the drive plate 320 and the sliding connecting plate 330 move closer to each other to press the compression spring 341. When the moving plate and sliding connecting plate 330 approach each other, the drive plate 320 contacts the pressure sensor 353. When the pressure sensor 353 senses pressure, the control mechanism 500 controls the XYZ moving platform 310 to stop driving the drive plate 320 to continue moving downwards, avoiding excessive pressure applied to the metal plate by the grinding wheel 362, and controlling the pressure applied to the metal plate by the grinding wheel 362 to be consistent, thereby ensuring that the pretreatment device 10 before paint coating spraying uniformly grinds the metal plate. The rotating motor 361 drives the grinding wheel 362 to rotate to grind the metal plate. The aforementioned pretreatment device 10 before paint coating spraying can uniformly grind the metal decorative panel.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
