Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a coating equipment for plastic product processing. Background Technique

[0002] Surface coating is a technology that forms a film layer on the surface of a substrate to improve its surface properties. The chemical composition and organizational structure of the coating layer can be completely different from those of the substrate material. It is based on the criteria of meeting surface properties, the bonding strength between the coating layer and the substrate material being able to adapt to working conditions, good economy, and good environmental protection. The thickness of the coating layer can be several millimeters or several micrometers. Usually, a machining allowance is reserved on the surface of the substrate part to achieve the required coating layer thickness for the working conditions. Compared with surface modification and surface treatment, surface coating belongs to the surface engineering technology of surface coating. Because of its fewer constraints and a large selection space for technical types and materials, there are many such surface engineering technologies and they are the most widely used. Plastics are mainly composed of carbon, oxygen, hydrogen, nitrogen, and other organic or inorganic elements. The finished product is solid, and it is in a molten liquid state during the manufacturing process. Therefore, it can be heated by machine to melt it, pressurized to make it flow, and cooled to solidify to form various shapes. This huge and diverse material group is called plastics. Plastics are very widely used and are indispensable components in household appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. After the plastic arc-shaped workpiece is processed, its surface also needs to be coated to improve its surface properties.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: including a base 1, the lower surface of the base 1 is fixedly connected with support legs 2 distributed in a rectangular array, the upper surface of the base 1 is fixedly connected with support columns 3 distributed symmetrically, the upper surfaces of the two support columns 3 are fixedly connected with mounting plates 4, the upper surface of the mounting plate 4 is fixedly connected with a material box 5, a feeding pump is arranged in the material box 5, and the feeding pump is responsible for transporting the material box 5 to the pipeline. The lower surface of the mounting plate 4 is fixedly installed with a first servo motor 6, the output shaft of the first servo motor 6 is fixedly connected with a first rotating shaft 7 through a coupling, one end of the first rotating shaft 7 is fixedly sleeved with a turntable 8, and one side surface of the turntable 8 is fixedly connected with a cylindrical block 9;

[0020] The lower surface of the mounting plate 4 is fixedly connected with L-shaped blocks 10 distributed symmetrically, the inner wall of the L-shaped block 10 is slidably sleeved with a sliding bar 11, and the sliding bar 11 freely slides in the inner wall of the L-shaped block 10.

[0021] Furthermore, one end of each of the two sliding bars 11 opposite to each other is fixedly connected with a long bar 12, and one end of the inner wall of the long bar 12 is movably inserted into the outer surface of the cylindrical block 9. With the cooperation of the L-shaped block 10 and the sliding bar 11, the rotation of the cylindrical block 9 can drive the long bar 12 to perform reciprocating motion.

[0022] Furthermore, one side surface of the long bar 12 is fixedly connected with a square plate 13, and the upper surface of the square plate 13 is fixedly installed with a second servo motor 14. The function of the second servo motor 14 is to drive the spray gun 23 to perform rotational motion, so that the paint sprayed by the spray gun 23 during operation is more uniform, so that it is more uniform when formed on the plastic arc workpiece, and the quality of the plastic arc workpiece is better.

[0023] Further, the output shaft of the second servo motor 14 is fixedly connected with a second rotating shaft 15 through a coupling. One end of the second rotating shaft 15 penetrates and extends to the lower surface of the square plate 13. A first gear 16 is fixedly sleeved on the outer surface of one end of the second rotating shaft 15. The second servo motor 14 drives the first gear 16 to rotate through the second rotating shaft 15.

[0024] Further, a circular tube 17 is installed on the inner wall of the square plate 13 through a bearing. A second gear 18 is fixedly sleeved on the outer surface of the circular tube 17. The tooth surface of the second gear 18 meshes with the tooth surface of the first gear 16. A fixing block 19 is fixedly connected to the upper surface of the square plate 13. The first gear 16 drives the circular tube 17 to rotate through the meshing second gear 18.

[0025] Further, a rotary joint 20 is fixedly installed on the inner wall of the fixing block 19. One end of the rotary joint 20 is fixedly communicated with one end of the circular tube 17. The other end of the rotary joint 20 is fixedly communicated with a hose 21. One end of the hose 21 is fixedly communicated with one side surface of the material box 5. The setting of the rotary joint 20 enables the hose 21 to remain unchanged and not rotate when the circular tube 17 rotates, preventing the problem that the rotation of the circular tube drives the hose to rotate and cause hose winding. And when the square plate 13 moves, the setting of the hose 21 can still keep the rotary joint 20 and the material box 5 in communication.

[0026] Further, annularly arrayed mounting blocks 22 are fixedly connected to the outer surface of the other end of the circular tube 17. Spray guns 23 are fixedly installed on the inner walls of the mounting blocks 22. One end of each spray gun 23 is fixedly communicated with a connecting pipe 24. One end of the connecting pipe 24 is fixedly communicated with the outer surface of the circular tube 17. The spraying material in the circular tube 17 is input into the spray guns 23 through the connecting pipes 24 for coating processing.

[0027] Through the settings of the cylindrical block, the long strip block and the rotary joint, the spray gun can perform reciprocating motion and rotational motion while spraying, so that the sprayed coating forms a more uniform coating on the surface of the workpiece, better improving the surface performance of the workpiece and enhancing the quality of the workpiece.

[0028] Working principle: Step 1, place the workpiece to be coated in the middle position of the base 1. Start the first servo motor 6. The first servo motor 6 drives the turntable 8 to rotate through the first rotating shaft 7. Under the cooperation of the L-shaped block 10 and the sliding strip 11, the rotation of the turntable 8 drives the long strip block 12 to perform reciprocating movement through the cylindrical block 9. The movement of the long strip block 12 drives the circular tube 17 to move through the square plate 13. The movement of the circular tube 17 drives the spray gun 23 to move through the mounting blocks 22.

[0029] Step 2: Start the second servo motor 14 simultaneously. The second servo motor 14 drives the first gear 16 to rotate through a rotating shaft. The rotation of the first gear 16 drives the circular tube 17 to rotate through the second gear 18 meshed therewith. The rotation of the circular tube 17 drives the paint gun 23 to rotate through the mounting block 22. Start the paint gun 23 to spray the paint. With the cooperation of the first servo motor 6 and the second servo motor 14, the paint gun 23 rotates while reciprocating, so that the coating range is larger and the coating is more uniform.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
