[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please refer to Figures 1-5.

[0022] A melamine tableware surface wear-resistant coating spraying equipment includes a conveyor base 1, a fixed seat 2 fixedly installed on the outer surface of the conveyor base 1, a connecting frame 3 fixedly installed on the outer surface of the fixed seat 2, a servo motor 4 fixedly installed on the outer surface of the connecting frame 3, a lead screw 5 fixedly installed at the output end of the servo motor 4, a sliding component 6 slidably connected to the outer surface of the lead screw 5, a mounting frame 7 fixedly installed on the outer surface of the sliding component 6, a hydraulic arm 8 fixedly installed on the outer surface of the mounting frame 7, a spraying head 9 and an electric telescopic rod 11 fixedly installed at the output end of the hydraulic arm 8, an inlet pipe 10 fixedly connected to the outer surface of the spraying head 9, a recovery hood 12 fixedly installed at the output end of the electric telescopic rod 11, the spraying head 9 being located inside the recovery hood 12, a recovery pipe 13 fixedly connected to the outer surface of the recovery hood 12, an exhaust gas processor 14 fixedly connected to the output end of the recovery pipe 13, and the exhaust gas processor 14 being fixedly connected to the fixed seat 2.

[0023] Specifically, the servo motor 4 drives the lead screw 5 to achieve precise horizontal movement and positioning of the spraying head 9; the hydraulic arm 8 adjusts the vertical position of the spraying head 9 to ensure effective spraying of melamine tableware of different heights; the electric telescopic rod 11 and the recovery hood 12 work together to collect unattached paint and exhaust gas during spraying, and finally treat them through the exhaust gas processor 14. The entire equipment works in concert to efficiently and accurately complete the spraying of the wear-resistant coating on the surface of melamine tableware, thereby improving production efficiency, ensuring spraying quality, and taking into account environmental protection requirements.

[0024] In the embodiment: a first protective baffle 15 is rotatably connected to the outer surface of the fixed base 2 near the frame 20, and a second protective baffle 16 is rotatably connected to the outer surface of the fixed base 2 away from the first protective baffle 15. Support frames are provided on the outer surfaces of both the first protective baffle 15 and the second protective baffle 16. An ultraviolet curing lamp 17 is fixedly installed on the outer surface of the fixed base 2.

[0025] Specifically, the first protective baffle 15, rotatably connected to the outer surface of the fixed base 2 near the frame 20, and the second protective baffle 16, rotatably connected to the outer surface away from the first protective baffle 15, can have their opening and closing angles adjusted by rotation. The support frames on the outer surfaces of both baffles provide support when the baffles are unfolded to a suitable angle, maintaining their stability. During operation, the first and second protective baffles 16 are unfolded and fixed by the support frames, forming a protective barrier surrounding the spraying area. This effectively blocks splashed paint during spraying, preventing paint from falling onto other parts of the equipment or the workshop environment, reducing cleaning workload, and preventing external debris from entering the spraying area and contaminating the coating, ensuring the cleanliness of the spraying environment. The ultraviolet curing lamp 17, fixedly installed on the outer surface of the fixed base 2, emits ultraviolet light to irradiate the coating surface after the melamine tableware has undergone wear-resistant coating spraying. The photosensitizer contained in the wear-resistant coating material undergoes a chemical reaction under ultraviolet light, promoting rapid curing of the coating.

[0026] In the embodiment: the spray head 9 adopts a multi-angle spray head 9, the recovery cover 12 is attached to the outer surface of the conveyor base 1, and the exhaust gas processor 14 adopts activated carbon adsorption, photocatalytic oxidation and plasma purification technology.

[0027] Specifically, the use of a multi-angle spray head 9 improves the comprehensiveness and uniformity of coating coverage; the closely connected recycling hood 12 enhances the efficiency of paint recycling and exhaust gas collection; and the exhaust gas processor 14, which combines multiple technologies, achieves deep purification of exhaust gas. The three work together to further optimize the quality, economy, and environmental friendliness of the melamine tableware wear-resistant coating spraying.

[0028] Working Principle: When this melamine tableware surface wear-resistant coating spraying equipment is working, the conveyor base 1 is used to carry and convey the melamine tableware. The fixed base 2 is stably installed on the outer surface of the conveyor base 1, providing support for the upper structure of the entire equipment. The connecting frame 3 extends outward from the fixed base 2, fixing the servo motor 4 on its outer surface. The servo motor 4 serves as a power source; after starting, its output end rotates, driving the lead screw 5 fixedly connected to it to rotate. When the lead screw 5 rotates, the sliding part 6 on the outer surface of the lead screw 5 slides linearly along the axial direction of the lead screw 5 due to the cooperation between the thread structure of the lead screw 5 and the sliding part 6. The movement of the sliding part 6 drives the mounting frame 7 fixed to it to move synchronously, thereby realizing the position adjustment of the mounting frame 7 in the direction of the lead screw 5. The hydraulic arm 8 on the mounting frame 7 has an extendable output end. When it is necessary to spray the melamine tableware, the hydraulic arm 8 extends, driving the spray head 9 fixed at its output end closer to the melamine tableware. The inlet pipe 10... The wear-resistant coating is continuously supplied to the spray head 9 through the liquid inlet pipe 10. The spray head 9 evenly sprays the coating onto the surface of the melamine tableware, completing the wear-resistant coating process. At the same time, the electric telescopic rod 11 is also installed on the mounting frame 7, with a recovery cover 12 fixed to its output end. The spray head 9 is located inside the recovery cover 12. When the spray head 9 is working, the electric telescopic rod 11 is adjusted according to the shape and position of the tableware, so that the recovery cover 12 is as close as possible to the spraying area. Some of the coating that is not attached to the surface of the tableware and the exhaust gas generated during the spraying process are collected by the recovery cover 12. The recovery pipe 13, which is fixedly connected to the outer surface of the recovery cover 12, transports the collected coating and exhaust gas to the exhaust gas processor 14. The exhaust gas processor 14 is fixedly connected to the mounting base 2 to purify the exhaust gas, reduce environmental pollution, and also recover some reusable coating, improving the utilization rate of the coating.

[0029] Compared with related technologies, the melamine tableware surface wear-resistant coating spraying equipment provided by this utility model has the following beneficial effects:

[0030] Example 2:

[0031] Please refer to Figures 1-5.

[0032] A frame 20 is fixedly installed on the outer surface of the conveyor base 1. A recording camera 21 is fixedly installed on the outer surface of the frame 20. Two electric telescopic frames 18 are provided at the lower part of the frame 20. Guides 19 are fixedly installed at the output ends of the two electric telescopic frames 18. The two electric telescopic frames 18 are fixedly connected to the conveyor base 1.

[0033] Specifically, when the tableware passes through the area, the recording camera 21 starts working and captures image information of the tableware surface through the lens. When melamine tableware of different sizes or shapes is conveyed on the conveyor base 1, the electric telescopic frame 18 automatically adjusts the telescopic length of the output end according to the specifications of the tableware, driving the guide 19 to move in position. The two guides 19 cooperate with each other to form a channel suitable for the current tableware to pass through, which plays a guiding and limiting role for the tableware, ensuring that the tableware maintains a stable posture and position during the conveying process and is accurately delivered to the spraying area, thereby achieving the effect of improving the reliability and adaptability of the melamine tableware wear-resistant coating spraying production.

[0034] In this embodiment: the two electric telescopic frames 18 are arranged in a V-shape, and sensors are provided on the outer surfaces of the guide 19 and the fixed base 2. A controller is provided on the outer surface of the conveyor base 1. The controller is electrically connected to the servo motor 4, the sensor, the hydraulic arm 8, the electric telescopic rod 11, the electric telescopic frame 18 and the recording camera 21.

[0035] Specifically, the two electric telescopic frames 18 are arranged in a V-shape, and the guide 19 at their output end forms a guide channel with a wide inlet and a narrow outlet. When melamine tableware is conveyed on the conveyor base 1, the V-shaped structure can use the gradually narrowing channel to naturally center and guide the tableware. With the length adjustment of the electric telescopic frame 18, it can adapt to the conveying and guiding needs of tableware of different sizes. The sensors on the outer surface of the guide 19 and the fixed base 2 can detect the position, size, and passage status of the tableware in real time and transmit the signals to the controller. The controller, as the core, is electrically connected to the servo motor 4, sensors, hydraulic arm 8, electric telescopic rod 11, electric telescopic frame 18, and recording camera 21. After receiving sensor signals, it issues commands to each component according to a preset program, such as adjusting the moving speed of the sliding part 6 driven by the servo motor 4, controlling the extension and retraction amplitude of the hydraulic arm 8 and electric telescopic rod 11, adjusting the length of the electric telescopic frame 18, and starting the recording camera 21. This realizes automated linkage control of the equipment, eliminating the need for manual operation of each component. The sensors accurately detect and provide data support to the controller, which responds quickly and coordinates the actions of each component, ensuring seamless connection of tableware conveying, positioning, spraying, and recording during the spraying process. This significantly improves the automation and continuity of production. The controller is an existing structure, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail, facilitating centralized control operation of the relevant structures.

[0036] Working Principle: The frame 20, fixed to the outer surface of the conveyor base 1, provides a stable mounting platform for the recording camera 21, enabling it to be aligned with the melamine tableware during the conveying process. When the tableware passes through this area, the recording camera 21 activates, capturing image information of the tableware surface through its lens. Two electrically operated telescopic frames 18 at the lower part of the frame 20 are fixedly connected to the conveyor base 1, providing power support for the guide 19. When melamine tableware of different sizes or shapes is conveyed on the conveyor base 1, the electrically operated telescopic frames 18 automatically adjust the extension length of their output ends according to the tableware specifications, driving the guide 19 to move. The two guides 19 cooperate to form a channel suitable for the current tableware, guiding and limiting the tableware, ensuring that the tableware maintains a stable posture and position during the conveying process. The equipment accurately delivers the melamine tableware to the spraying area, solving the problem of misalignment and tilting that easily occurs during the conveying process. This ensures that the tableware can accurately enter the spraying position, improves the positioning accuracy of the spraying head 9 for the tableware, and thus improves the spraying quality. At the same time, it enhances the adaptability of the equipment to different types of tableware, eliminating the need for frequent replacement of conveying guide components and improving production flexibility and efficiency. Compared with related technologies, the melamine tableware surface wear-resistant coating spraying equipment provided by this utility model has the following beneficial effects: thereby achieving the effect of improving the reliability and adaptability of melamine tableware wear-resistant coating spraying production.
