[0002] A canvas spraying machine is a device designed for efficient completion of large-area painting or decorative design. Its core principle is to use compressed air to atomize liquid pigments and spray them evenly onto the canvas surface. These machines are typically equipped with adjustable pressure valves, multi-size nozzles, and flow controllers, enabling the creation of various effects from delicate gradients to rough textures. They are particularly suitable for mural creation, billboard painting, or textile printing.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] In actual production, existing canvas spraying machines typically require the entire image to be sprayed first when the required pattern size is always larger than the canvas specifications. Then, the canvas is removed from the machine and processed again using external cutting equipment. This method requires frequent loading and unloading of the canvas, which not only reduces production efficiency but also increases the risk of canvas damage due to improper operation.

[0005] Therefore, this solution provides a canvas spraying machine to solve the above problems. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides a canvas spraying machine, including a spraying mechanism 1 and a worktable mechanism 2. The spraying mechanism 1 is arranged above the worktable mechanism 2. A limiting mechanism 3 is provided on one side of the spraying mechanism 1. Symmetrical cutting mechanisms 4 are provided at both ends of one side of the limiting mechanism 3. A limiting edge mechanism 5 is provided on one side of each cutting mechanism 4.

[0034] The spraying mechanism 1 includes a Y-guide rail 11, an X-direction moving seat 12 and a spraying assembly 13, and the worktable mechanism 2 includes a spraying table 21 and a canvas 23 passing above the spraying table 21.

[0035] The limiting mechanism 3 includes a mounting frame 31 and two symmetrical limiting grooves 32 opened on one side of the mounting frame 31;

[0036] The cutting mechanism 4 includes an integrated mounting frame 41 and a sliding block 402. The bottom of the mounting frame 41 is provided with a mounting slot 42, and the cutting blade 49 is provided inside the mounting slot 42.

[0037] The edge limiting mechanism 5 includes a receiving plate 58 fixedly connected to one side of the mounting frame 41, a sliding plate 51 and a limiting frame 53 on one side of the receiving plate 58;

[0038] The vertical height of the limiting slide groove 32 is higher than that of the sliding block 402, which allows the cutting mechanism 4 and the edge limiting mechanism 5 to be lifted, thereby allowing the positions of the two cutting mechanisms 4 and the edge limiting mechanism 5 to slide freely. In addition, this part can be replaced with a positive and negative lead screw and a handwheel or motor can be installed on the outside. The positive and negative lead screw is threaded through the sliding block 402, thereby allowing the distance between the two cutting mechanisms 4 to be adjusted electrically or manually at the same time.

[0039] In a further embodiment, the mounting frame 41 has limit grooves 43 on both sides, and mounting sliders 44 are slidably connected inside the limit grooves 43. The mounting sliders 44 are located on both sides of the cutting blade 49, and the upper and lower ends of the mounting sliders 44 are respectively fixedly connected to connecting rods 46 and springs 45.

[0040] In this embodiment, the mounting slot 42 divides the bottom of the mounting frame 41 into two parts, thereby allowing the cutting blade 49 to be inserted. The spring 45 is used to always push the installed cutting blade 49, thereby adapting to working conditions where cutting is not required.

[0041] In a further embodiment, mounting bolts 401 are inserted into the mounting slider 44 and the cutting blade 49, a pressure plate 47 is fixedly connected to the top of the connecting rod 46, a pressing bolt 48 is threadedly connected to the top of the pressure plate 47, and the bottom of the pressing bolt 48 is rotatably connected to the top of the mounting frame 41.

[0042] In this embodiment, after the pressure bolt 48 is rotated, it will force the pressure plate 47, the connecting rod 46 and the mounting slider 44 to move down, thereby taking the cutting blade 49 installed between the mounting sliders 44 down with it. The distance of the downward movement can be controlled by rotating the pressure bolt 48 a few turns, which also allows the cutting blade 49 to pre-mark the edge of the canvas.

[0043] In a further embodiment, a docking tooth 403 is provided below the sliding block 402, and a limiting tooth 33 is fixedly connected to the inner side of the limiting groove 32. The docking tooth 403 fits into the limiting tooth 33, and two symmetrical guide wheels 404 are rotatably connected above the sliding block 402.

[0044] In this embodiment, the engagement of the docking tooth 403 and the limiting tooth 33 can restrict the position of the cutting mechanism 4, while the guide wheel 404 is used to facilitate contact with the inner top surface of the limiting groove 32 after being lifted up, thereby reducing friction and making it easier to slide.

[0045] In a further embodiment, a portion of the sliding plate 51 is slidably connected in the groove of the receiving plate 58, and a second spring 52 is provided above it. A pressing roller 54 is rotatably connected below the limiting frame 53, and an abutting roller 55 is provided on the inner side of the limiting frame 53.

[0046] In this embodiment, the receiving plate 58 is provided with a sliding groove for the sliding plate 51 to slide up and down. One side of the sliding plate 51 has a protrusion so that it can slide in the groove. The second spring 52 allows the sliding plate 51, the limiting frame 53 and the pressing roller 54 to press down. When the cutting blade 49 does not need to cut, the pressing roller 54 can help position the canvas 23 and is still used to prevent the canvas 23 from shifting.

[0047] In a further embodiment, the upper and lower ends of the abutment roller 55 are rotatably connected to the receiving slider 56, the receiving slider 56 is slidably connected to the inner side wall of the limiting frame 53, and a spring 57 is provided on one side of the receiving slider 56.

[0048] In this embodiment, the edge roller 55 is used to conform to the new edge of the cut canvas, thereby limiting and preventing displacement.

[0049] In a further embodiment, the X-axis moving seat 12 is located on both sides of the Y-axis guide rail 11, the spraying assembly 13 is slidably connected to one side of the Y-axis guide rail 11, the mounting bracket 31 is installed on the other side of the Y-axis guide rail 11 by screws, guide rollers 22 are provided at both ends of the spraying table 21, and the X-axis moving seat 12 is slidably connected to the edge of the spraying table 21.

[0050] In this embodiment, the spraying mechanism 1 and the worktable mechanism 2 constitute a canvas spraying device in the prior art. The spraying mechanism 1 is externally equipped with a control device that can operate other devices. When operating, the X-axis moving seat 12 moves in the X-axis of the spraying table 21, while the spraying component 13 slides within the range limited by the Y-axis guide rail 11, thereby sliding in the Y-axis of the canvas 23. The canvas 23 is sprayed with a picture by moving the spraying component 13 in the XY direction. The two ends of the canvas 23 are connected to a conveying roller and a take-up roller, which are not shown in the figure.

[0051] The working principle of this utility model is as follows:

[0052] When the external controller manipulates the guide roller 22 to move the canvas 23 to the upper surface of the spraying table 21, the Y guide rail 11, the X moving seat 12 and the spraying assembly 13 work together to spray the set picture onto the surface of the canvas 23, thereby performing the spraying operation.

[0053] Before spraying, the cutting mechanism 4 and the edge limiting mechanism 5 can be raised according to the size of the painting to prevent the docking tooth 403 from engaging with the limiting tooth 33. This allows the cutting mechanism 4 and the edge limiting mechanism 5 to slide within the limiting groove 32, so that the bottom of the cutting blade 49 can be aligned with the part to be cut. Then, the cutting mechanism 4 and the edge limiting mechanism 5 are lowered, allowing the docking tooth 403 and the limiting tooth 33 to re-engage. Then, the pressure plate 47, the connecting rod 46 and the mounting slider 44 are manually rotated to move the cutting blade 49 down, so that the cutting blade 49 contacts and pierces the canvas 23. Then, the spraying mechanism 1 is operated. During the operation, the X-axis moving seat 12 will move along the X-axis of the spraying table 21, so that the cutting blade 49 cuts the canvas. This allows the canvas to be cut in the X-axis during the spraying process, reducing the subsequent cutting time and improving the processing efficiency.

[0054] After the canvas 23 is cut by the cutting blade 49, the rebound of the second spring 52 will cause the sliding plate 51, the limiting frame 53 and the pressing roller 54 to move down. The downward movement of the pressing roller 54 can press down the waste material to be cut, thereby helping to separate the part of the canvas with the picture from the waste part. At the same time, the pressing roller 55 will also move down with the limiting frame 53, so that the outer edge of the pressing roller 55 contacts the new edge of the canvas after cutting, and limits the new edge to prevent the canvas from shifting during cutting.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
