Description

Technical Field

[0001] This utility model relates to the field of ceramic processing equipment technology, and in particular to a ceramic surface coloring device. Background Technology

[0002] Ceramics are inorganic non-metallic materials made primarily from natural minerals such as clay, quartz, and feldspar through processes including molding, drying, and firing. They possess characteristics such as high hardness, strong chemical stability, and high-temperature resistance. To imbue ceramics with artistic value, meet aesthetic needs, and differentiate their uses, they require coloring treatments.

[0003] In the field of ceramic surface coloring, traditional processes and equipment face numerous technical bottlenecks, hindering improvements in production efficiency and product quality. Existing technologies, manual spraying processes heavily rely on operator experience, easily leading to uneven coating thickness and missed areas, resulting in poor product consistency. Automated equipment using fixed nozzles struggles to achieve full coverage of complex curved surfaces such as cup bottoms and inner wall corners, creating significant blind spots. Furthermore, paint storage and transportation also present challenges. Traditional static storage tanks require additional stirring devices to maintain pigment uniformity, increasing energy consumption and structural complexity, while pigment sedimentation remains difficult to avoid, further affecting color consistency and the stability of the spraying effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ceramic surface coloring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ceramic surface coloring device includes a base, on which a material trough, a placement platform, and a fixing frame are provided. A cylinder is fixedly mounted on the fixing frame. Positioning plates are fixedly mounted on the telescopic end of the cylinder and the upper surface of the placement platform. A movable box is provided on the placement platform via a movable mechanism. A paint spray head is fixedly mounted on the side of the movable box. A drive motor is provided on the movable box via a support plate. The drive motor is connected to the placement platform via a rotating mechanism. A pump body is provided inside the movable box. An inlet pipe and an outlet pipe are installed on the pump body. The inlet pipe is located in the material trough, and the outlet pipe is connected to the paint spray head.

[0007] Preferably, the movable mechanism includes a movable frame fixedly installed at the bottom of the movable box, and the upper surface of the placement platform is provided with a movable groove corresponding to the movable frame.

[0008] Preferably, the rotating mechanism includes a gear fixedly mounted on the output shaft of the drive motor, and a gear ring meshing with the gear is fixedly mounted on the placement platform.

[0009] Preferably, both the feed pipe and the discharge pipe are rigid pipes, and multiple stirring rods are fixedly installed on the feed pipe.

[0010] Preferably, the vertical cross-sectional view of the movable frame and the movable groove is L-shaped, and the outer wall of the movable frame and the inner wall of the movable groove are both polished.

[0011] Preferably, both the upper and lower positioning plates are provided with protective pads, which are made of rubber and have anti-slip textures on their surfaces.

[0012] The beneficial effects of this utility model are:

[0013] 1. The circular track design allows the spray gun to rotate 360° around the workpiece, avoiding dead angles and uneven thickness problems caused by manual spraying. It is especially suitable for spraying the inner and outer walls of rotating ceramics such as cups and bowls.

[0014] 2. The feed pipe integrates a stirring function, eliminating the need for additional stirring equipment, simplifying the structure while ensuring coating uniformity and improving coloring quality.

[0015] 3. The rubber anti-slip pads on the positioning plate not only prevent damage to the ceramics, but also stabilize the workpiece during rotary spraying, reducing the defect rate.

[0016] 4. The ring motion is achieved through gear and ring gear meshing, which has a small footprint and low maintenance cost. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3A ceramic surface coloring device includes a base 1, a material trough 2, a placement platform 3, and a fixing frame 6 on the base 1. A cylinder 7 is fixed on the fixing frame 6. Positioning plates 8 are fixed on the telescopic end of the cylinder 7 and the upper surface of the placement platform 3. A movable box 9 is provided on the placement platform 3 through a movable mechanism. A paint spray head 10 is fixed on the side of the movable box 9. A drive motor 12 is provided on the movable box 9 through a support plate 11. The drive motor 12 is connected to the placement platform 3 through a rotating mechanism. A pump body 14 is provided inside the movable box 9. An inlet pipe 15 and an outlet pipe 17 are installed on the pump body 14. The inlet pipe 15 is located in the material trough 2, and the outlet pipe 17 is connected to the paint spray head 10.

[0023] The movable mechanism includes a movable frame 13 fixedly mounted at the bottom of the movable box 9, and a movable groove 4 corresponding to the movable frame 13 on the upper surface of the placement platform 3. Both the movable frame 13 and the movable groove 4 have L-shaped vertical cross-sections, and the outer wall of the movable frame 13 and the inner wall of the movable groove 4 are polished. This L-shaped design prevents the movable box 9 from moving vertically relative to the placement platform 3, allowing it to move only in a circular motion along the movable groove 4. The polishing process ensures smooth movement of the movable frame 13 relative to the movable groove 4.

[0024] The rotating mechanism includes a gear 18 fixedly mounted on the output shaft of the drive motor 12, and a gear ring 5 fixedly mounted on the placement platform 3 that meshes with the gear 18. After the drive motor 12 is started, it can drive the gear 18 to rotate. Since the gear ring 5 is fixedly mounted, the movable box 9 and the paint spray head 10 and other components will run in a ring around the placement platform 3.

[0025] Both the feed pipe 15 and the discharge pipe 17 are rigid pipes, and multiple stirring rods 16 are fixedly installed on the feed pipe 15. The feed pipe 15 can run in a ring within the material tank 2, and together with the stirring rods 16, it realizes the stirring and mixing operation of the material, thus preventing sedimentation.

[0026] Both the upper and lower positioning plates have protective pads on their surfaces. These pads are made of rubber and have anti-slip textures. The protective pads reduce damage to the porcelain, and the anti-slip textures prevent slipping and ensure the stability of the porcelain.

[0027] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0028] In use, the ceramic workpiece is placed between two positioning plates 8, and the positioning plates 8 are clamped by the cylinder 7. A rubber protective pad prevents damage to the workpiece. The drive motor 12 drives the gear 18 to rotate, which meshes with the fixed gear ring 5, forcing the movable box 9 to move in a ring, causing the spray head 10 to rotate around the ceramic workpiece. The pump body 14 draws paint from the material tank 2 through the feed pipe 15 and delivers it to the spray head 10 through the discharge pipe 17, achieving spraying on the ceramic surface. The feed pipe 15 rotates synchronously with the movable box 9, and the stirring rod 16 on it continuously stirs the paint in the material tank 2 to prevent pigment sedimentation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
