Description

Technical Field

[0001] This utility model relates to a raw material crushing device, and more particularly to a raw material crushing device for new material processing, belonging to the field of new material processing technology. Background Technology

[0002] New materials refer to structural materials with excellent performance and functional materials with special properties that have been recently developed or are under development. New materials are classified into four categories according to their composition: metallic materials, inorganic non-metallic materials (such as ceramics, gallium arsenide semiconductors, etc.), organic polymer materials, and advanced composite materials. They are also classified into structural materials and functional materials according to their material properties. In recent years, the types of new materials researched and developed worldwide mainly include composite new materials, superconducting materials, energy materials, smart materials, magnetic materials, nanomaterials, etc. Some new materials require shear crushers to crush the raw materials during processing.

[0003] Current technologies still have shortcomings:

[0004] The existing shear crushers for new material processing lack protective limiting components at the top. Due to the lack of effective protection during crushing operations, material splashing is prominent, which not only significantly increases the workload of subsequent cleaning operations but also causes material waste. Secondly, during the feeding stage, it is difficult to limit and guide the material to the working area of ​​the crushing roller. In particular, for long strips or long cylindrical materials, slippage is likely to occur without limiting, requiring manual assistance for positioning. This not only fails to ensure feeding stability but also poses a very high risk of mechanical injury.

[0005] To address this issue, a new material crushing device for material processing was designed to optimize the aforementioned problems. Utility Model Content

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a new material crushing device for material processing, including a frame 1 and a crushing chamber 2 installed on the top of the frame 1. Crushing rollers 13 are symmetrically installed inside the crushing chamber 2. A fixed shaft 11 and a movable shaft 12 are fixed to the ends of the crushing rollers 13 respectively. Gears 15 are sleeved on the ends of both the fixed shaft 11 and the movable shaft 12. A motor 10 is installed on the top of the frame 1, and the output shaft of the motor 10 is fixedly connected to the end of the fixed shaft 11.

[0036] The top of the crushing chamber 2 is equipped with a shell 3. Hydraulic cylinders 4 are symmetrically hinged to the top wall of the shell 3. The telescopic end of the hydraulic cylinder 4 is hinged to an outer shell 5. Inside the outer shell 5, a rotating roller 6 and a limiting roller 7 are rotatably installed at both ends respectively. A sleeve 16 is installed through both sides of one end of the outer shell 5, and the sleeve 16 is rotatably connected to the shell 3 through a bearing. A limiting band 8 is provided between the rotating roller 6 and the limiting roller 7. A linkage mechanism 9 is provided between the shell 3, the movable shaft 12, and the fixed shaft 11. A limiting component 14 is provided inside the crushing chamber 2.

[0037] Hydraulic cylinder 4 is activated according to the size of the new material. Hydraulic cylinder 4 drives the outer shell 5 to rotate around the sleeve 16, causing the limiting roller 7 at one end of the outer shell 5 to move up and down, adjusting the distance between the limiting roller 7 and the inner wall of the feed end of the crushing chamber 2, so that the distance left can allow the material to pass through. The linkage mechanism 9 drives the rotating roller 6 and the limiting roller 7 to rotate, causing the limiting belt 8 to push the material into the crushing chamber 2. Then, the motor 10 is activated to drive the fixed shaft 11 to rotate, which drives the movable shaft 12 to rotate in the opposite direction through the gear 3 15. This causes the two sets of crushing rollers 13 to rotate relative to each other, crushing the material. At the same time, the fragments splashed during the crushing process are blocked by the limiting belt 8 and fall back onto the crushing rollers 13. The inclined limiting belt 8 cooperates with the incoming material to prevent the fragments from splashing outward.

[0038] Example 2

[0039] The solution in Example 1 will be further described below with reference to its specific working method.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the linkage mechanism 9 further includes a driving wheel 901, a driven wheel 903, and a rotating shaft 902. The driving wheel 901 is respectively sleeved and installed on the outside of the fixed shaft 11 and the outside of the movable shaft 12. The rotating shaft 902 is symmetrically arranged on the outside of the housing 3, and the end of the rotating shaft 902 passes through the sleeve 16 and extends into the inside of the housing 5 and is fixedly connected to the center position of the rotating roller 6. The rotating shaft 902 is rotatably connected to the sleeve 16. Gear 906 is sleeved on the outside of the rotating shaft 902. The driven wheel 903 is symmetrically installed on the outside of the housing 3 and is rotatably connected to the outside of the housing 3. A belt 904 is provided between the driven wheel 903 and the driving wheel 901. Gear 905 is fixed on one side of the driven wheel 903 through an intermediate shaft. Gear 905 meshes with gear 906.

[0041] While the motor 10 drives the fixed shaft 11 and the movable shaft 12 to rotate, the fixed shaft 11 and the movable shaft 12 respectively drive the drive wheel 901 to rotate. The drive wheel 901 drives the driven wheel 903 and the first gear 905 to rotate through the belt 904. The first gear 905 drives the second gear 906 to rotate in the opposite direction. The second gear 906 drives the rotating roller 6 to rotate through the rotating shaft 902. Then, in conjunction with the limiting roller 7, the limiting belt 8 rotates along the outside of the rotating roller 6 and the limiting roller 7, pushing the raw material placed in the feed port of the crushing chamber 2 into the crushing chamber 2.

[0042] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the limiting component 14 further includes an isolation block 1401 and a guide plate 1402. The guide plate 1402 is fixed on the inner side wall of the crushing chamber 2 and located above the crushing roller 13. The bottom of the guide plate 1402 is uniformly fixed with the isolation block 1401, and the isolation block 1401 is offset from the blade position of the crushing roller 13.

[0043] When the crushing roller 13 rotates, the outer blades slide in contact with the isolation block 1401. The isolation block 1401 scrapes the crushed material hanging on the crushing roller 13 away from the blade surface, while the guide plate 1402 protects the top of the isolation block 1401 to prevent the splashed fragments from falling and getting stuck in the gap of the isolation block 1401, and at the same time guides the material.

[0044] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the guide plate 1402 is further installed obliquely inside the crushing chamber 2, and the isolation block 1401 is a trapezoidal structure block.

[0045] The inclined guide plate 1402 can closely guide the raw material to gather towards the center of the crushing roller 13, reducing off-center loading; the trapezoidal isolation block 1401 fits more closely with the guide plate 1402.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, the limiting band 8 is further annular wear-resistant band, and the outer surface of the limiting band 8 is uniformly provided with anti-slip ridges, the height of which is 2-5mm.

[0047] The annular wear-resistant belt extends service life, and the anti-slip ridges enhance friction with long strip materials, preventing slippage and deviation during feeding, ensuring continuous and stable feeding, and making it suitable for conveying highly elastic materials.

[0048] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the belt 904 is a synchronous belt, and the outer sides of both the driving pulley 901 and the driven pulley 903 are provided with tooth grooves that are compatible with the belt 904.

[0049] The synchronous belt and toothed drive are non-slip, ensuring precise matching of the rotation speeds of the roller 6 and the crushing roller 13, improving the coordination of pushing and crushing actions, and reducing power loss and material jamming.

[0050] like Figure 5 As shown, in a preferred embodiment, based on the above method, both ends of the sleeve 16 are provided with angular contact ball bearings, and a sealing ring is provided on the outside of the bearing. The sealing ring is made of fluororubber.

[0051] The angular contact ball bearing enhances the axial load capacity of sleeve 16, making it suitable for rotating sleeve 16 under stress; the fluororubber seal is resistant to high and low temperatures and chemical corrosion, effectively preventing dust intrusion and ensuring rotational accuracy and component life.

[0052] Example 3

[0053] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0054] Based on the size of the new material, first start the hydraulic cylinder 4, drive the outer shell 5 to rotate around the sleeve 16, drive the limit roller 7 to move up and down, adjust the distance between the limit roller 7 and the inner wall of the feed end of the crushing chamber 2 to ensure that the material can be properly fitted and passed through, until the limit belt 8 can fit on the top of the material.

[0055] After the motor 10 is started, its output shaft drives the fixed shaft 11 to rotate, which in turn drives the movable shaft 12 to rotate in the opposite direction through the gear 3 15, thereby causing the symmetrical crushing roller 13 to rotate in the opposite direction synchronously, forming the basic power for crushing operations.

[0056] During operation of motor 10, fixed shaft 11 and movable shaft 12 synchronously drive drive wheel 901 to rotate. Drive wheel 901 drives driven wheel 903 and gear 905 to rotate via belt 904. Gear 905 meshes and drives gear 906 to rotate in the opposite direction. The rotation is transmitted to roller 6 via shaft 902. In conjunction with limit roller 7, limit belt 8 is driven to rotate along the outside of roller 6 and limit roller 7. The friction force is used to stably push the raw material at the feed port into crushing chamber 2.

[0057] During the crushing process, the inclined limiting belt 8 simultaneously blocks the splashing of crushed material, causing the splashed material to fall back to the crushing roller 13 for further crushing, ensuring a clean working environment and high raw material utilization.

[0058] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
