Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rice milling machine shell, and in particular relates to a rice milling machine shell cutting device. Background Technology
[0002] Using the high pressure and a certain polishing speed of the polishing chamber, the brown rice grains rub against each other and against the parts of the rice milling equipment to remove the bran layer. This process grinds the brown rice and removes the bran without requiring high polishing chamber pressure; it is also known as speed rice milling.
[0003] Without proper positioning during the cutting of the rice milling machine casing, deviations in the cutting path can lead to uneven surfaces, wavy or serrated marks, and potential problems during subsequent casing assembly and surface treatment. Therefore, we need to design a rice milling machine casing cutting device that uses a swing-type positioning structure to position the casing. This ensures the cut material conforms to the design, preventing twists, skewing, and other irregular shapes, guaranteeing the casing's appearance quality and the regularity of its internal space. Positioning also makes the cutting process more stable and the cutting path more accurate, resulting in smoother, flatter cut surfaces and improved overall rice milling machine casing cutting quality.

[0023] In the following description, embodiments of the rice milling machine casing cutting device of the present invention will be described with reference to the accompanying drawings.
[0024] Figure 1-4This invention illustrates a rice milling machine casing cutting device according to an embodiment of the present invention. It includes a worktable 1, a cutter 2 fixedly mounted on the top of the worktable 1, and fixed plates 3 fixedly connected to both the left and right sides of the worktable 1. Two symmetrical fixed blocks 4 are fixedly connected to the top of each of the two fixed plates 3. A mounting rod 5 is fixedly connected to the side of the two fixed blocks 4 on the left side facing each other. The mounting rod 5 is rotatably connected to an L-shaped plate 6. Through the cooperation of the mounting rod 5 and the L-shaped plate 6, the mounting rod 5 guides the L-shaped plate 6 as it rotates on the surface of the mounting rod 5, ensuring that the L-shaped plate 6 can rotate smoothly. The positioning circular plate 8 presses the outer shell tightly, improving the stability of the L-shaped plate 6 during rotation. The L-shaped plate 6 is located on the opposite side of the two fixed blocks 4 on the left. A mounting plate 7 is fixedly connected to the top of the L-shaped plate 6, and the positioning circular plate 8 penetrates the surface of the mounting plate 7. The mounting plate 7 is fixedly connected to the positioning circular plate 8. A spring 9 is installed in the inner cavity at the bottom of the worktable 1. The two ends of the spring 9 are welded to the top of the inner cavity of the worktable 1 and the L-shaped plate 6, respectively. The spring 9 provides a rebound effect on the L-shaped plate 6 when it swings, ensuring the stability of the positioning circular plate 8 on the outer shell. The fixed plate 8 is tightly fixed, which improves the stability of the positioning plate 8 during use. A fixing rod 11 is fixedly connected to one side of the two fixing blocks 4 facing each other on the right side. A movable plate 12 is provided in the inner cavity at the bottom of the worktable 1. A pressure block 10 is provided through the right side of the L-shaped plate 6, and the pressure block 10 is fixedly connected to the L-shaped plate 6 and contacts the movable plate 12. A rotating block 13 is fixedly connected to the right side of the top of the movable plate 12, and the rotating block 13 is slidably connected to the fixing rod 11. A connecting plate 14 is fixedly connected to the top of the rotating block 13, and a fixing round block 15 is fixedly connected to the bottom of the connecting plate 14. The right-side fixing plate 3... A cylinder 17 is provided on the left side, and the output end of the cylinder 17 is fixedly connected to the moving plate 12. A support plate 16 is fixedly connected to the side of the two fixed blocks 4 facing each other on the right side. The cylinder 17 is fixedly installed on the top of the support plate 16. Through the setting of the support plate 16, the support plate 16 supports the cylinder 17 during use, which improves the cylinder 17 from detaching from the moving plate 12. Four placement blocks 18 are fixedly connected to the top of the workbench 1. The surface of the L-shaped plate 6 is provided with a circular groove for the mounting rod 5 to pass through. The surface of the rotating block 13 is provided with a hole for the fixed rod 11 to slide.
[0025] Working principle: When using this utility model, the user first places the outer shell on top of the placement block 18. At this time, the positioning circular plate 8 and the fixing circular block 15 do not fix the outer shell, so the moving plate 12 and the pressure block 10 are in a close fit. By opening the cylinder 17 on the top of the support plate 16, the output end of the cylinder 17 will drive the moving plate 12 to move downward. At the same time, the moving plate 12 will disengage from the L-shaped plate 6. Then, the L-shaped plate 6 will rotate on the surface of the mounting rod 5. Due to the setting of the spring 9, the L-shaped plate 6 will rebound, so that the L-shaped plate 6 will drive the positioning circular plate 8 to fix one side of the outer shell through the mounting plate 7, so that one side of the outer shell is fixed. Then, the moving plate 12 will drive the rotating block 13 to slide downward on the surface of the fixing rod 11. Then, the rotating block 13 will drive the fixing circular block 15 to press and fix the outer shell through the connecting plate 14. After the fixing circular block 15 fixes the outer shell, the cylinder 17 on the top of the support plate 16 will be closed, so that the cutting machine 2 will cut the outer shell.
[0026] In summary, this rice milling machine outer shell cutting device, by placing the outer shell on top of the placement block 18, and then using the cooperation of the moving plate 12, the L-shaped plate 6, and the rotating block 13, fixes the positioning circular plate 8 and the fixing circular block 15 on both sides, thereby allowing the cutting machine 2 to cut the outer shell on top of the placement block 18. This achieves the goal of positioning the outer shell of the rice milling machine using a swinging positioning structure, ensuring that the shape of the cut plate meets the design expectations, avoiding irregular shapes such as twisting and skewing, guaranteeing the appearance quality of the outer shell and the regularity of the internal space. Positioning makes the cutting process more stable and the cutting path more accurate, resulting in a smoother and flatter cut surface, thus improving the cutting quality of the rice milling machine outer shell.
