Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing equipment, and in particular to a frame and leaf-beating device. Background Technology
[0002] The frame is a fixed component on the leaf-crushing and re-drying machine in the leaf-crushing industry. After the leaf-crushing machine breaks the leaves, they fall through the frame onto a belt conveyor for subsequent air separation and classification processes. Currently, in leaf-crushing and re-drying production lines, the openings in the leaf-crushing machine frame are generally diamond-shaped. These openings are machined into holes on a sheet of a specific thickness, rolled into a circle, and the cutting edge of the frame is 8mm flat. The frame is semi-circular, and the cutting blade is mounted on a rotating roller. The roller shaft is concentric with the frame. During operation, the frame is fixed, and the cutting blade rotates with the roller, with the cutting edge always pointing towards the center of the circle along the frame. The frame and cutting blade work together to compress and tear the leaves, reducing their size. The disadvantage is that the material is easily broken and generates dust, affecting the subsequent air separation and classification processes. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a frame and leaf-beater that reduces the breakage and dust generated when the material is squeezed and torn by the blade and the frame, resulting in uniform material and improved leaf-beating efficiency.
[0004] This utility model provides a frame, wherein the frame has a slanted blade on the side away from the beating roller.
[0005] In one specific embodiment of this utility model, the frame surface is provided with openings.
[0006] In one specific embodiment of this utility model, the opening is rhomboid in shape, and the edge of the opening is beveled.
[0007] In a specific embodiment of this utility model, the frame is prepared by: machining diamond-shaped holes on a specific plate, rolling it into a round shape, milling bevels on both sides, and making beveled edges on the diamond-shaped holes to make the edge of the frame sharp.
[0008] In one specific embodiment of this utility model, the frame is semi-circular.
[0009] This utility model provides a leaf-beating device, including a main box, an arc gate, a protective cover, a drive motor, a frame, a frame mounting bracket, and a beating roller;
[0010] The frame mounting bracket and the roller are mounted on the main body, and the frame described in the above technical solution is fixedly mounted on the frame mounting bracket;
[0011] The cutting blade is mounted on the beating roller, and the shaft of the beating roller is concentric with the frame. During operation, the frame is fixed, and the cutting blade rotates with the beating roller. The cutting edge of the cutting blade always points to the center of the circle along the frame.
[0012] Compared with existing technologies, the frame of this invention, by sharpening the blades on the side away from the beating roller, creates a shearing surface between the blades on the beating roller and the frame, thereby transforming the squeezing and tearing forces on the tobacco leaves at the beating roller and frame into squeezing and shearing forces. This makes it easier to shear the leaves, reducing breakage and dust generation. The inclined surface of the frame near the housing allows the tobacco leaves to slide down promptly, where they are squeezed and sheared by the blades at the frame's edge, falling through the holes onto the collection belt. This prevents the tobacco leaves from accumulating and clumping, reducing the amount of foreign matter to be removed in subsequent impurity removal processes. Attached Figure Description

[0021] To further understand this utility model, the embodiments of this utility model are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting this utility model.
[0022] An embodiment of this utility model discloses a leaf-beater, such as... Figures 1-2 As shown, it includes the main body 1, the arc gate 2, the protective cover 3, the drive motor 4, the frame 5, the frame mounting bracket 6, and the beating roller 7;
[0023] The frame mounting bracket and the roller are installed on the main body, and the frame is fixedly installed on the frame mounting bracket.
[0024] The striking blade is installed on the striking roller 7. The shaft of the striking roller 7 is concentric with the frame 5. During operation, the frame 5 is fixed, and the striking blade rotates with the striking roller 7. The blade edge always points to the center along the frame 5.
[0025] The other structures of the leaf-beater are the same as those in the prior art.
[0026] like Figures 3-7 As shown, the frame 5 is sharpened on the side away from the beating roller 7, with the sharp edge close to the beating roller 7.
[0027] The frame 5 has openings on its surface. The openings are diamond-shaped with beveled edges.
[0028] The frame 5 is prepared by: machining diamond-shaped holes on a specific plate, rolling it into a round shape, milling bevels on both sides, and making beveled edges on the diamond-shaped holes to make the cutting edge of the frame sharp.
[0029] The frame 5 used in this invention has an angled blade, which creates a shearing surface between the blade on the beating roller 7 and the frame 5. This transforms the squeezing, tearing, and tensile forces on the tobacco leaves at the beating roller 7 and frame 5 into squeezing and shearing forces, making it easier to shear the leaves, improving beating efficiency, and reducing breakage and dust. Leaves falling onto the frame 5 near the casing will slide off promptly. Figure 4 As shown, the tobacco leaves are squeezed and sheared at the edge of the frame and fall onto the collection belt through the holes. This prevents the tobacco leaves from accumulating and caking into clumps, reducing the amount of foreign matter to be removed in subsequent impurity removal processes.
[0030] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
