Technical Field
[0001] This utility model relates to the field of roller mill technology, specifically a mixing and grinding device that is easy to assemble and disassemble. Background Technology
[0002] Roller mills, as an important material handling equipment, are widely used in many industrial fields such as building materials, chemicals, metallurgy, and mining. They mainly process lumpy or granular materials to the required particle size and uniformity through crushing and mixing. They are one of the key pieces of equipment to ensure the smooth operation of subsequent production processes. During the long-term use of roller mills, the maintenance, repair, and replacement of vulnerable parts are important aspects to ensure their continuous and efficient operation.
[0003] The existing roller mill has a problem because the roller is located inside the mill, and the protective barrel on the outside of the mill cannot be moved downwards, which prevents workers from disassembling the roller. This makes it time-consuming to disassemble the parts inside the mill, which affects work efficiency. Therefore, improvements are needed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] This utility model provides the following technical solution:
[0026] Example 1
[0027] Please see Figure 1-5This utility model provides a technical solution: a mixing and grinding device that is easy to assemble and disassemble, including a base 4, a fixed barrel 1 fixedly connected to the top of the base 4, an assembly and disassembly mechanism 3 arranged around the fixed barrel 1, and a mixing and grinding mechanism 2 arranged on the top of the fixed barrel 1.
[0028] The disassembly and assembly mechanism 3 includes a top back end of a limit frame 36. A hydraulic cylinder 35 is fixedly connected to the top of the limit frame 36. A slide plate 37 is fixedly connected to the bottom of the hydraulic cylinder 35. A linkage frame 31 is fixedly connected to the left and right sides of the slide plate 37. A sealing barrel 34 is fixedly connected to the inner side of the linkage frame 31. A sliding block 32 is fixedly connected to the outer side of the sealing barrel 34. A support frame 33 is slidably connected inside the sliding block 32. The support frame 33 is fixedly connected to the top of the base 4.
[0029] Furthermore, the inner side of the limiting frame 36 is provided with a sliding groove corresponding to the movement trajectory of the slide plate 37, and the slide plate 37 is slidably connected to the inside of the sliding groove. Through the sliding groove, the slide plate 37 can slide inside the limiting frame 36, so that the slide plate 37 can drive the linkage frame 31 to move, and the linkage frame 31 can drive the sealing barrel 34 to move up and down.
[0030] Furthermore, the sealing barrel 34 is slidably connected to the periphery of the fixed barrel 1, and the inner side of the sealing barrel 34 is in close contact with the outer side of the fixed barrel. After the sealing barrel 34 moves downward, it is convenient for the staff to disassemble and replace the rolling roller 21 and the mixing plate 28.
[0031] Example 2
[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, the mixing and grinding mechanism 2 further includes a drive motor 26, which is fixedly connected to the inside of the fixed barrel 1. A rotating shaft 25 is fixedly connected to the top of the drive motor 26, and a fixed plate 27 is fixedly connected to the top of the rotating shaft 25. A protective cylinder 29 is fixedly connected to the bottom periphery of the fixed plate 27. An mounting plate 24 is provided on the top of the fixed plate 27. Bolts 23 are threadedly connected to the inner side of the mounting plate 24. Inclined plates 22 are fixedly connected to the left and right sides of the mounting plate 24. A crushing roller 21 is rotatably connected to the outer side of the inclined plate 22. A mixing plate 28 is fixedly connected to the front of the mounting plate 24.
[0033] Furthermore, the protective cylinder 29 is set on the top of the fixed barrel 1, the bottom of the protective cylinder 29 is in close contact with the top of the fixed barrel 1, and the rotating shaft 25 is slidably connected to the inside of the protective cylinder 29. The protective cylinder 29 can protect the rotating shaft 25, so that the crushed material is less likely to affect the use of the rotating shaft 25.
[0034] Furthermore, the bottom of the mounting plate 24 fits into the top of the fixing plate 27, and the bolt 23 is threaded into the inside of the fixing plate 27. Through the bolt 23, the mounting plate 24 can be installed onto the top of the fixing plate 27, allowing the operator to disassemble the inclined plate 22 and the rolling roller 21.
[0035] Furthermore, the crushing roller 21 is disposed on the top of the fixed barrel 1, and the bottom of the crushing roller 21 is in contact with the top of the fixed barrel 1. The crushing roller 21 can crush the material on the top of the fixed barrel 1.
[0036] In actual operation, when this device is used, the material is poured into the top of the fixed bucket 1, the drive motor 26 is turned on, and the drive motor 26 drives the fixed plate 27 and the mounting plate 24 to rotate through the rotating shaft 25. The mounting plate 24 drives the crushing roller 21 to rotate through the inclined plate 22, so that the crushing roller 21 can crush the material at the top of the fixed bucket 1. When the mounting plate 24 rotates, it drives the mixing plate 28 to rotate, so that the mixing plate 28 can mix the material at the top of the fixed bucket 1. The mixing plate 28 can push the crushed material to the bottom of the crushing roller 21, so that the crushing roller 21 can repeatedly crush the crushed material.
[0037] When it is necessary to disassemble the rolling roller 21 and the mixing plate 28, the operator opens the hydraulic cylinder 35, which drives the sliding plate 37 to move downward. The sliding plate 37 can then drive the sealing barrel 34 to move downward through the linkage frame 31. This allows the sealing barrel 34 to drive the sliding block 32 to slide on the support frame 33, so that the bottom of the sealing barrel 34 can contact the top of the base 4. This allows the operator to rotate the bolt 23, moving it away from the inside of the fixing plate 27, which facilitates the disassembly and maintenance of the rolling roller 21 and the mixing plate 28 on the top of the fixing barrel 1.
[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
