Description

Technical Field

[0001] This utility model relates to the field of grinding roller technology, specifically to a flour grinding roller with low hardness and high wear resistance. Background Technology

[0002] Grinding rollers are core components of industrial grinding equipment, primarily used to crush materials into fine powder through crushing or grinding. They are widely used in mining, chemical, cement, and flour processing industries. In flour processing, flour grinding rollers are the core component of flour mills, bearing high loads and rotational speeds.

[0003] For example, announcement number CN220310567U, entitled "A flour milling roller that is easy to disassemble," includes a first shaft head, a roller body, and a second shaft head. One end of the roller body is connected to the first shaft head, and an adjustment structure is provided between the first shaft head and the roller body. The end of the roller body opposite to the first shaft head is connected to the second shaft head, and a connecting structure is provided between the roller body and the second shaft head. The ends of the first and second shaft heads opposite to the roller body are respectively rotatably connected to the side wall of the flour mill. This device solves the problem of needing to disassemble the entire equipment when repairing or replacing the milling roller, allowing the roller body to be disassembled separately, facilitating the replacement or repair of the flour milling roller, saving time and effort, and reducing maintenance costs.

[0004] While the existing flour milling rollers are easy to disassemble during use, they are assembled using a single snap-fit ​​structure, resulting in poor overall assembly stability and potential safety risks under high loads and speeds. Therefore, they do not meet current requirements, and a flour milling roller with low hardness and high wear resistance is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a flour grinding roller with low hardness and high wear resistance, in order to solve the problem mentioned in the background art that the existing flour grinding rollers are assembled with a single snap-fit ​​structure, resulting in poor overall assembly stability and safety risks under high load and speed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flour milling roller with low hardness and high wear resistance, comprising: a roller, both ends of which are provided with assembly grooves, a roller shaft assembly is installed inside the assembly groove, the roller shaft assembly includes a shaft, one end of the shaft is provided with an assembly block, the assembly block is inserted into the assembly groove, and a limiting accessory for limiting and fixing the assembly block is installed on the outer wall of the assembly block.

The guide block limiting grooves are provided with a second docking hole. A second bolt is installed in the second docking hole and extends through the second docking hole into the guide block screw hole.

[0011] Preferably, the first arc-shaped limiting frame is provided with a limiting slot on its end wall, and limiting plates are provided on both sides of the lower opening of the limiting slot. The second arc-shaped limiting frame is provided with a limiting block on its end wall, and the limiting block engages with the limiting slot.

[0012] Preferably, a magnetic absorbing assembly slot is provided at the inner center of the combined assembly slot, and a magnetic absorbing assembly block is installed at the center of one end of the combined assembly block.

[0014] Preferably, a rubber roller sleeve is provided on the outer wall of the roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, the roller assembly is inserted into the assembly block and the assembly groove. The insertion depth restricts the roller assembly from the roller. On this basis, the limiting assembly restricts the assembly block, making it more difficult for the limiting assembly to separate from the roller, thus improving the assembly firmness.

[0017] (2) In this utility model, when the combined assembly block is inserted into the combined assembly groove, the limiting guide block will move within the limiting guide groove to ensure alignment during the insertion process and to restrict the insertion. The first docking hole on the first arc-shaped limiting frame and the second arc-shaped limiting frame is used to align with the screw hole of the cylinder. The first bolt is used to install the first bolt, which fixes the two arc-shaped limiting frames to the end wall of the roller. The guide block limiting groove opened on the first arc-shaped limiting frame and the second arc-shaped limiting frame is used to fit the limiting guide block. The first arc-shaped limiting frame is installed above the combined assembly block, and the second arc-shaped limiting frame is installed below the combined assembly block. The two arc-shaped limiting frames form a ring that restricts the combined assembly block at its center and aligns with the screw hole of the guide block through the second docking hole. The second bolt is then used to fix the combined assembly block, thus restricting the combined assembly block. The above structure is simple to install, easy to operate, and has high combined strength, which is conducive to bearing high loads and speeds.

[0018] (3) In this utility model, when installing the limiting assembly, the first arc-shaped limiting frame is first installed and fixed on the top of the combined assembly block, and then the second arc-shaped limiting frame is inserted into the limiting slot through the limiting block, so that the displacement of the second arc-shaped limiting frame is restricted. Then the second arc-shaped limiting frame is combined and assembled with the combined assembly block, which makes it convenient for users to quickly align the screw holes and facilitates the combined installation.

When installing the limiting assembly 3, the first arc-shaped limiting frame 301 is first installed and fixed above the combined assembly block 202. Then, the second arc-shaped limiting frame 302 is inserted into the limiting slot 306 through the limiting block 310, so that the displacement of the second arc-shaped limiting frame 302 is restricted. Then, the second arc-shaped limiting frame 302 is combined and assembled with the combined assembly block 202, which facilitates the user to quickly align the screw holes and makes it easy to perform combined installation.

[0032] Please see Figure 2 , Figure 3 A magnetic assembly groove 104 is provided at the inner center of the assembly groove 101, and a magnetic assembly block 206 is installed at the center of one end of the assembly block 202.
