Description

Technical Field

[0001] This utility model relates to the field of ore crushing technology, and in particular to a pressure-resistant roller. Background Technology

[0002] In industries such as mining, metallurgy, and building materials, roller presses are core equipment for ore crushing, grinding, and forming. The performance of its core component, the pressure roller, directly determines the equipment's efficiency, energy consumption, and service life. Roller presses are designed based on the principle of bed grinding, and their main characteristics are: high pressure, full speed, full material supply, and bed crushing. A roller press consists of two opposing, synchronously rotating extrusion rollers, one fixed and one movable. Material is fed from above the rollers and continuously drawn into the space between them by the extrusion rollers. After being subjected to a high pressure of 100-150 MPa, it is transformed into a dense cake and discharged from the bottom of the machine. The discharged cake contains a certain proportion of fine particles. Numerous cracks are generated inside the non-finished particles, improving the grindability of the material and significantly reducing grinding energy consumption during further crushing. The pressure roller of the roller press is a very critical and important component. Currently, the pressure roller structure of roller presses generally adopts an integral roller sleeve baked on the roller shaft. The roller sleeve is a wear part, and its main failure mode is roller surface wear and peeling. After the roller sleeve fails, the roller press needs to be disassembled, the old pressure roller removed, and a new pressure roller replaced, or it can be repaired by welding on site and reused. However, the downtime is long, the welding quality is difficult to guarantee, the cost is high, and it directly affects the overall machine operating rate.

[0003] Chinese patent CN220610614U discloses a roller press pressure roller, relating to the field of roller press technology. This roller press pressure roller includes a roller press body, a roller shaft rotatably connected to the roller press body, and a roller sleeve sleeved on the roller shaft. The roller sleeve is annularly fitted onto the roller shaft and consists of multiple arc-shaped connecting plates with rotating holes. When the roller sleeve needs to be installed on the roller shaft, it is fitted onto the roller shaft, and the fixing blocks are engaged in the fixing grooves. Then, by rotating a threaded rod through a screwdriver groove, the two fixing blocks move in opposite directions. As the fixing blocks move, their transverse plates engage in the transverse grooves of the fixing grooves, thus fixing the two adjacent connecting plates. This allows the roller sleeves to be replaced individually according to their degree of damage, reducing the cost of overall replacement and making the replacement process more convenient and faster.

[0004] However, in practical applications, it has been found that the roller sleeves composed of curved plates will wear and loosen after a long period of use, and the installation and fixing process is quite complicated. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a pressure-resistant roller tire that can simplify the installation process while ensuring that the parts can be disassembled and replaced at will, and ensures the stability and pressure resistance of the connection, and is not easy to loosen during use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A pressure-resistant roller tire includes two sets of roller mechanisms that rotate in opposite directions. Each set of roller mechanisms includes a roller shaft connected to a drive mechanism, a roller sleeve fitted on the roller shaft, a connecting sleeve for connecting the roller shaft and the roller sleeve, and a support frame for connecting and installing the roller mechanism onto the main body of a roller press. The two ends of the roller shaft are detachably mounted on the support frame. The roller sleeve includes a first ring sleeve unit and a second ring sleeve unit alternately mounted on the connecting sleeve. The second ring sleeve unit is composed of multiple detachable sector blocks spliced ​​together, and each sector block has an extension plate integrally formed and connected to both ends.

[0008] Furthermore, the connecting sleeve includes an annular body, with a plurality of inner protruding ridges arranged parallel to each other on the inner side of the annular body, and a plurality of first grooves opened parallel to each inner protruding ridge on the roller shaft, and the connecting sleeve is slidably engaged in the first grooves through the inner protruding ridges.

[0009] Furthermore, the inner wall of the first groove is covered with an anti-slip rubber pad.

[0010] Furthermore, the outer side of the annular body is provided with several protruding ridges in parallel, the inner side of the first ring sleeve unit is provided with a second groove corresponding to the protruding ridges, the arc-shaped inner side of the fan-shaped block is provided with a third groove corresponding to the protruding ridges, and the extension plate is provided with an opening groove corresponding to the protruding ridges.

[0011] Furthermore, the thickness of the protruding ridge is greater than the thickness of the extension plate.

[0012] Furthermore, one end of the roller shaft is provided with a fixed baffle, and the other end of the roller shaft is provided with a detachable limiting baffle. A limiting pin is provided on the outer side of the limiting baffle, and a limiting hole is provided on the roller shaft corresponding to the limiting pin.

[0013] The beneficial effects of this utility model are:

[0014] In practical applications, during installation, first, the connecting sleeve is fitted onto the roller shaft. Then, the first ring sleeve unit is fitted onto the end of the connecting sleeve. Next, the sector blocks are assembled, with the extension plate at one end of the sector block inserted between the first ring sleeve unit and the connecting sleeve. This allows the first ring sleeve unit to secure the sector block. This process is repeated to assemble multiple sector blocks into a complete second ring sleeve unit. Another first ring sleeve unit is then fitted, securing the extension plate at the other end of the sector block in the second ring sleeve unit. Depending on the length of the roller, the first and second ring sleeve units are assembled using the same method until the entire roller assembly is complete. The assembly process requires minimal screws and other fasteners, making installation quicker. Afterward, the roller shaft is securely connected to the roller press using a support frame. During use, the connecting sleeve increases the overall strength of the roller. Combined with the outer roller sleeve, it ensures compressive strength while facilitating component replacement, saving on wear and replacement costs. If any part of the roller sleeve is damaged, it can be easily removed, replaced, and reassembled, making the process quick and convenient. This invention allows for easy disassembly and replacement of components while simplifying the installation process, ensuring connection stability and pressure resistance, and preventing loosening during use.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] like Figure 1-4As shown, this utility model provides a pressure-resistant roller tire, including two sets of roller mechanisms that rotate in opposite directions. Each set of roller mechanisms includes a roller shaft 1 connected to a drive mechanism, a roller sleeve 2 fitted on the roller shaft 1, a connecting sleeve 3 for connecting the roller shaft 1 and the roller sleeve 2, and a support frame for connecting and installing the roller mechanism onto the main body of the roller press. The two ends of the roller shaft 1 are detachably mounted on the support frame. The roller sleeve 2 includes a first ring sleeve unit 21 and a second ring sleeve unit alternately mounted on the connecting sleeve 3. The second ring sleeve unit is composed of multiple detachable sector blocks 22 spliced ​​together. Each sector block 22 has an extension plate 23 integrally formed and connected to both ends.

[0021] In this embodiment, during installation, the connecting sleeve 3 is first fitted onto the roller 1, then the first ring unit 21 is fitted onto the end of the connecting sleeve 3, and then the sector block 22 is assembled. The extension plate 23 at one end of the sector block 22 is inserted between the first ring unit 21 and the connecting sleeve 3, so that the sector block 22 can be fixed by the first ring unit 21. The above actions are repeated to assemble multiple sector blocks 22 into a complete second ring unit. Then, another first ring unit 21 is fitted, and the extension plate 23 at the other end of the sector block 22 of the second ring unit is fixed. According to the length of the roller, the first ring unit 21 and the second ring unit are assembled according to the above installation method until the assembly of the entire roller is completed. The entire assembly process does not require the use of too many screws or other fasteners, making the installation faster. Then, the roller 1 is fixedly connected and installed onto the roller press using a support frame (a conventional structure, not shown in the figure). During use, the connecting sleeve 3 increases the overall strength of the roller. Together with the outer roller sleeve 2, it ensures compressive strength while facilitating component replacement, saving on wear and replacement costs. If any part of the roller sleeve 2 is damaged, it can be directly removed, replaced, and then reassembled quickly and conveniently. This compression roller ensures easy disassembly and replacement of components while simplifying the installation process, guaranteeing connection stability and compressive strength, and preventing loosening during use.

[0022] like Figure 1 and Figure 3 As shown, the connecting sleeve 3 includes an annular body 31. A plurality of inner protruding ribs 32 are arranged parallel to each other on the inner side of the annular body 31. A plurality of first grooves 11 are opened parallel to each inner protruding rib 32 on the roller shaft 1. The connecting sleeve 3 is slidably fitted into the first groove 11 via the inner protruding ribs 32. In this embodiment, the inner protruding ribs 32 and the annular body 21 are integrally cast to ensure overall strength. The connecting sleeve 3 is slidably fitted into the first groove 11 via the inner protruding ribs 32, making the installation method very simple. The cross-sections of the inner protruding ribs 32 and the first groove 11 are both polygonal structures, at least triangular, which can effectively prevent lateral displacement and enhance stability.

[0023] like Figure 1As shown, an anti-slip rubber pad is laid on the inner wall of the first groove 11. In this embodiment, the anti-slip rubber pad serves to prevent slipping and effectively reduce friction between the two parts, reduce wear, and extend the service life of the parts.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the annular body 31 is provided with several protruding ridges 33 in parallel. The inner side of the first ring sleeve unit 21 is provided with a second groove 211 corresponding to the protruding ridges 33. The arc-shaped inner side of the fan-shaped block 22 is provided with a third groove 221 corresponding to the protruding ridges 33. The extension plate 23 is provided with an opening groove 231 corresponding to the protruding ridges 33. In this embodiment, the various assembly components of the sleeve 2 and the connecting sleeve 3 are also connected by sliding snap-fit. The cross-sections of the protruding ridges, the second groove 211 and the third groove 221 are all polygonal structures, at least triangular, which can effectively prevent lateral displacement and make the stability stronger. This device simplifies the installation method and makes it more practical.

[0025] like Figure 1 As shown, the thickness of the outer protruding rib 33 is greater than the thickness of the extension plate 23. In this embodiment, the thickness of the outer protruding rib 33 is greater than the thickness of the extension plate 23, which can ensure that the second groove 211 on the inner side of the first ring sleeve 21 can form a snap-fit ​​with the connecting sleeve 3, preventing rotation during use and affecting the working effect of the roller press.

[0026] like Figure 1 As shown, one end of the roller shaft 1 is provided with a fixed baffle 12, and the other end of the roller shaft 1 is provided with a detachable limiting baffle 13. A limiting pin 14 is provided on the outer side of the limiting baffle 13, and a limiting hole is provided on the roller shaft 1 corresponding to the limiting pin 14. In this embodiment, a fixed baffle 13 is provided at one end of the roller shaft 1 as a fixed limiting end to avoid excessive disassembly and assembly. The limiting baffle 13 at the other end facilitates the disassembly and assembly of the roller sleeve 2, and the structure is simple.

[0027] All technical features in this embodiment can be modified in appearance according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
