Description

Technical Field

[0001] The utility model relates to the field of distributors, in particular to a multi-roller distributor structure. Background Technique

[0002] The multi-roller distributor is usually installed under the feeding mud roller of the sintering machine or the powder belt feeder, which plays a role in reasonable distribution and control of material segregation, making the material distribution more uniform and the material surface more flat. As the distribution roller rotates, a part of the fine-grained mixture falls from the gap of the distribution roller onto the upper layer of the sintering machine trolley, resulting in particle size segregation of the material layer. At the same time, it plays a role in loosening the mixture and also increases the small balls in the mixture. By adjusting the rotation speed of the multi-roller distributor, the degree of particle size segregation of the mixture can be controlled, and appropriate segregation of fixed carbon in the material layer can be achieved.

[0003] In the common multi-roller distributor, through the rotation of multiple conveying rollers, the powder is distributed downward through the gaps between the conveying rollers. As the multi-roller distributor operates, the rotation of the conveying rollers will cause wear, and the conveying rollers need to be replaced. The two ends of the conveying rollers are usually rotationally connected to the driving mechanism by bearings. When replacing the conveying rollers, it is usually necessary to disassemble the mounting seats at both ends of the conveying rollers and disassemble the whole conveying rollers, resulting in difficulties in installation and disassembly of the conveying rollers and inconvenience in replacing the conveying rollers.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides as Figures 1-3A multi-roller distributor structure shown includes a mounting frame 1, conveying rollers 2, a mounting mechanism 3, and a pushing mechanism 4. The mounting frame 1 is used to mount the conveying rollers 2. The conveying rollers 2 are arranged horizontally between the mounting frames 1. A plurality of conveying rollers 2 are arranged between two mounting frames 1. The mounting mechanism 3 is arranged at one end of the conveying rollers 2. The mounting mechanism 3 is used to form a movable structure at one end of the conveying rollers 2 and fix the conveying rollers 2. Through the mounting mechanism 3, it is convenient to install and fix the conveying rollers 2 and facilitate the disassembly and replacement of the conveying rollers 2. The pushing mechanism 4 is arranged on the mounting mechanism 3. The pushing mechanism 4 is used to form a moving mechanism on the mounting mechanism 3 and disassemble the conveying rollers 2. Through the pushing mechanism 4, it is convenient to adjust the mounting mechanism 3.

[0033] The mounting mechanism 3 includes a mounting seat 31, a movable groove 32, a limiting block 33, a limiting groove 34, and a compression spring 35. The mounting seat 31 is arranged at one end of the conveying roller 2. The mounting seat 31 is arranged in a cylindrical shape. Two mounting seats 31 are respectively arranged at both ends of the conveying roller 2. The conveying roller 2 is installed and fixed through the two mounting seats 31. The other end of the mounting seat 31 is fixedly connected with a rotating shaft for driving the mounting seat 31 and the conveying roller 2 to rotate. The movable groove 32 is opened at the middle position of one end of the mounting seat 31. The movable groove 32 is arranged as a square groove for installing the limiting block 33. One end of the limiting block 33 is slidably inserted into the inner cavity of the movable groove 32. The limiting block 33 is arranged in a square block shape. One end of the limiting block 33 is arranged in a trapezoidal shape. One end of the mounting seat 31 and the conveying roller 2 are connected through the limiting block 33, so that the mounting seat 31 drives the conveying roller 2 to rotate together. The limiting groove 34 is arranged at one end of the conveying roller 2. The inner cavity of the limiting groove 34 is slidably inserted into one end of the limiting block 33. The limiting groove 34 is used to install the limiting block 33. By vertically moving the conveying roller 2 downward, the conveying roller 2 is arranged between two mounting seats 31 on the same straight line, so that one end of the conveying roller 2 presses against the inclined surface of one end of the limiting block 33, pushing the limiting block 33 to slide into the inner cavity of the movable groove 32, and the other end of the limiting block 33 compresses and deforms the compression spring 35. The compression spring 35 is arranged in the inner cavity of the movable groove 32. One end of the compression spring 35 is attached to the other end of the limiting block 33. As the conveying roller 2 moves, the limiting groove 34 moves to the position of the limiting block 33. Using the elastic action of the compression spring 35, one end of the limiting block 33 is pushed to slide into the inner cavity of the limiting groove 34 to limit the connection between the mounting seat 31 and the conveying roller 2, so that the mounting seat 31 drives the conveying roller 2 to rotate together.

[0034] The driving mechanism 4 includes a first bolt 41, a mounting groove 42, a pressing block 43, a connecting groove 44, a second bolt 45 and a positioning hole 46.

The mounting groove 42 is arranged on the top of the mounting seat 31. The bottom of the inner wall of the mounting groove 42 is threadedly connected to the bottom of the first bolt 41. The mounting groove 42 is used to mount and accommodate the first bolt 41. The upper surface of the pressing block 43 is rotatably connected to the bottom end of the first bolt 41. The pressing block 43 is arranged in a triangular block shape. The pressing block 43 moves in the vertical direction as the first bolt 41 rotates, and is used to press the limiting block 33. The connecting groove 44 is arranged on the top of the other end of the limiting block 33. The inner cavity of the connecting groove 44 is slidably inserted and connected with the pressing block 43. The connecting groove 44 is used to mount the pressing block 43. By rotating the first bolt 41, the pressing block 43 is driven to move vertically downward. The inclined surface at the bottom of the pressing block 43 presses against the inclined surface at the bottom of the inner wall of the connecting groove 44, so that the limiting block 33 slides into the inner cavity of the movable groove 32, which is convenient for releasing the connection between the mounting seat 31 and the conveying roller 2. The second bolt 45 is threadedly inserted and connected with the bottom of the mounting seat 31. The positioning hole 46 is arranged at the bottom of the other end of the limiting block 33. The inner cavity of the positioning hole 46 is slidably inserted and connected with the top of the second bolt 45. By rotating the second bolt 45, the top of the second bolt 45 slides into the inner cavity of the positioning hole 46 to limit and fix the limiting block 33, ensuring the stable connection between the mounting seat 31 and one end of the conveying roller 2. The bottom of the inner wall of the connecting groove 44 is inclined, and the inner wall of the connecting groove 44 is attached to the outer wall of the pressing block 43.
