Description

Technical Field

[0001] This utility model relates to the field of canvas production technology, specifically to a canvas coating uniform application device. Background Technology

[0002] Oil canvas is a type of canvas specifically designed for oil painting. It is typically made of natural fibers such as cotton and linen. Its surface undergoes special treatments, such as applying a primer, to improve the adhesion and even absorption of paint. Oil canvas has good strength and durability, making it suitable for long-term preservation. Based on the texture, oil canvas can be divided into coarse, medium, and fine textures to meet the needs of different styles and techniques. Oil canvas comes in various sizes and shapes, allowing artists to choose according to their creative needs. Compared to paper, oil canvas is easier to preserve and less prone to damage, making it an important medium for oil painting.

[0003] Currently, the production of canvases requires the use of coating devices to apply a coating. When coating canvases, it is necessary to apply the coating to canvases of different widths. However, current canvas coating is usually done using a coating roller. When feeding the coating roller, the entire roller is usually fed at once. This means that a coating roller of a certain length can only coat canvases of one size. When coating canvases of other sizes, it is easy to cause over-coating, which affects the coating effect on the canvas. Utility Model Content

[0025] The feeding mechanism is located inside the working box 2. The feeding mechanism includes a connecting box 6, a discharge pipe 7, and a conical block 8. The connecting box 6 is fixedly installed on the front and rear inner walls of the working box 2. The connecting box 6 is located above the coating roller 5. Electric push rods 9 are fixedly installed on both the left and right ends of the upper surface of the connecting box 6. The number of electric push rods 9 is the same for both sets. The telescopic ends of the two sets of electric push rods 9 slide through into the interior of the connecting box 6. The discharge pipe 7 is fixedly installed on the lower surface of the connecting box 6. The conical block 8 is divided into two groups and fixedly installed on the telescopic ends of the two sets of electric push rods 9.

[0027] Furthermore, by activating the electric push rod 9, the electric push rod 9 drives the conical block 8 to close or open the corresponding discharge pipe 7, and then the coating material reaches the outer surface of the coating roller 5 through the opened discharge pipe 7, and the canvas is coated. This device can process canvases of multiple sizes, which facilitates the coating of canvases.

[0028] Furthermore, both ends of the two collection boxes 10 are threaded with fixing bolts 11, and the four fixing bolts 11 are threaded through into the corresponding mounting plates 4. The two collection boxes 10 are fixedly mounted on the two mounting plates 4 by the four fixing bolts 11.

[0029] Furthermore, three connecting pipes 12 are fixedly installed on the left surface of the connecting box 6. The right ends of the three connecting pipes 12 all penetrate into the interior of the connecting box 6, and the upper ends of the three connecting pipes 12 all penetrate into the upper surface of the working box 2.

[0030] Furthermore, drive motors 13 are fixedly installed on the front surface of the work box 2 at the positions corresponding to the two application rollers 5.

This allows the device to coat canvases of multiple sizes. After the operation is completed, the coating material to be coated can be sent to the interior of the connecting box 6 through the three connecting pipes 12. The coating material inside the connecting box 6 is then sent to the outer surface of the upper coating roller 5 through the opened discharge pipe 7. The drive motor 13, which is fixedly connected to the coating roller 5, drives the coating roller 5 to rotate, thus coating the canvas between the two coating rollers 5. The two collection boxes 10 collect and scrape off any coating material that may fall or be added to the coating roller 5, so that the coating roller 5 can evenly coat the canvas. After use, the movable door 16 at the three rectangular holes 15 can be opened to remove the fixing bolts 11 on the collection box 10, thereby removing the two collection boxes 10 and recycling the coating material inside.
