Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a canvas coating device. Background Technology

[0002] In the field of canvas coating, with the development of industries such as art creation and industrial decoration, the demand for diversity and precision in canvas coating is increasing. Spraying, as a common coating method, is widely used in various canvas coating devices due to its high efficiency and uniformity.

[0003] Among them, the spray coating device uses a spray gun to atomize the paint and spray it onto the canvas surface. The spray coating device can adjust parameters such as the spray shape, spray pressure and paint flow rate of the spray gun as needed, and is suitable for partial coating of canvas or drawing complex patterns and textures.

[0004] Currently, most canvas coating equipment on the market uses a fixed installation method for its spraying components, with fixed spraying direction and angle. This makes it difficult to adapt to the coating needs of canvases of different shapes and sizes. When dealing with irregularly shaped canvases, such as irregularly shaped art canvases or specially shaped industrial canvases, the spraying component angle cannot be adjusted, which easily leads to spraying blind spots. This results in some areas not being effectively coated, requiring manual re-spraying, which reduces production efficiency and makes it difficult to ensure the uniformity and consistency of the coating.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a canvas coating device, including a support base 1, a feeding roller 2, a tensioning roller 13 and a take-up roller 10;

[0033] An adjustment device is provided on the support base 1;

[0034] The adjusting device includes a spraying assembly 14, a second rotating block 5, and two support plates 3. The two support plates 3 are fixedly connected to the upper surface of the support base 1. The spraying assembly 14 is rotatably connected to the outer wall of one side of the corresponding support plate 3 via a rotating shaft. The second rotating block 5 is rotatably connected to the outer wall of the left support plate 3. One end of the rotating shaft on the spraying assembly 14, near the second rotating block 5, extends rotatably to the outside of the left support plate 3 and is fixedly connected to one end of the second rotating block 5. Multiple scale strips 15 are provided on the outer wall of the left support plate 3. A connecting pipe 17 is installed on the outer wall of the spraying assembly 14. A connector 7 is fixedly connected to the lower outer wall of the left support plate 3. The end of the connecting pipe 17 away from the spraying assembly 14 is connected to the connector 7. Multiple spray nozzles are provided on the spraying assembly 14. Multiple fixing bolt grooves 18 are provided on the outer wall of the left support plate 3. The multiple fixing bolt grooves 18 are arranged in a circle. A protrusion 9 is fixedly connected to the outer wall of the second rotating block 5. A fixing bolt 8 is threadedly connected to the outer wall of the protrusion 9. The thread of the fixing bolt 8 near the fixing bolt groove 18 extends to the outside of the protrusion 9 and is respectively connected to the internal thread of the corresponding fixing bolt groove 18.

[0035] Among them, the outer walls of the opposite sides of the two support plates 3 are grooved and rotatably connected to threaded rods 16. The mounting seats at both ends of the tension roller 13 are rotatably connected to the outer walls of the corresponding threaded rods 16. The upper surfaces of the two support plates 3 are rotatably connected to first rotating blocks 4. The ends of the two threaded rods 16 near the first rotating blocks 4 extend to the outside of the support plates 3 and are fixedly connected to the ends of the corresponding first rotating blocks 4. The opposite sides of the two support plates 3 are rotatably connected to guide rollers 12. The ends of the take-up roller 10 are rotatably connected to the outer walls of the opposite sides of the corresponding support plates 3. The ends of the feed roller 2 are rotatably connected to the outer walls of the opposite sides of the two support plates 3 away from the take-up roller 10. The left support plate 3 near the feed roller 2 is fixedly mounted with a first motor 6. The output end of the first motor 6 extends to the outside of the left support plate 3 and is fixedly connected to the end of the feed roller 2. The left support plate 3 near the take-up roller 10 is fixedly mounted with a second motor 11. The output end of the second motor 11 extends to the outside of the left support plate 3 and is fixedly connected to the end of the take-up roller 10.

[0036] Furthermore, when using the device, it is started by connecting to an external power source. Based on the characteristics of the canvas and coating requirements, the operator rotates the first rotating block 4. The rotation of the first rotating block 4 drives the threaded rod 16, which is fixedly connected to it, to rotate. Since the mounting seats at both ends of the tension roller 13 are threadedly connected to the outer wall of the threaded rod 16, the tension roller 13 moves up and down along the threaded rod 16 when the threaded rod 16 rotates, thereby adjusting the height of the tension roller 13 to achieve a suitable tension on the canvas. Next, the operator rotates the second rotating block 5. The second rotating block 5 is connected to the rotating shaft on the spraying assembly 14, causing the spraying assembly 14 to rotate around the rotating shaft. During rotation, the operator can refer to the scale strip 15 on the outer wall of the left support plate 3 to adjust the spraying assembly 14 to the required position. After adjusting the spraying angle, screw the fixing bolt 8 into the corresponding fixing bolt groove 18 to fix the angle of the spraying assembly 14. Connect the external coating material supply source to the connector 7. The coating material is transported to the spraying assembly 14 through the connecting pipe 17 to prepare for the coating work. Start the first motor 6 and the second motor 11. The first motor 6 drives the feeding roller 2 to rotate, releasing the canvas to be coated from the feeding roller 2. The second motor 11 drives the take-up roller 10 to rotate, so that the canvas is smoothly transported from the feeding roller 2 to the take-up roller 10 under the guidance and tension of the guide roller 12 and the tension roller 13. When the canvas passes under the spraying assembly 14, the multiple nozzles on the spraying assembly 14 spray the coating material evenly onto the canvas, completing the coating operation of the canvas.

[0037] The operator then rotates the second rotating block 5 through the adjustment device. The second rotating block 5 is connected to the rotating shaft on the spraying assembly 14, causing the spraying assembly 14 to rotate around the rotating shaft. During the rotation, the operator can refer to the scale strip 15 on the outer wall of the left support plate 3 to adjust the spraying assembly 14 to the required spraying angle. After adjustment, the fixing bolt 8 is screwed into the corresponding fixing bolt groove 18 to fix the angle of the spraying assembly 14. This avoids the need for manual re-spraying in some areas that cannot be effectively coated, thereby improving production efficiency and the practicality of the equipment.
