Description

Technical Field

[0001] The utility model relates to the technical field of cement production, and more specifically, to a cement roller press. Background Art

[0002] In current technology, a key step in the cement production process is to flatten the cement using a roller press. This process is critical to ensuring cement quality and consistency. The main function of the roller press is to uniformly press the cement raw materials into slabs of the required thickness and density for subsequent processing and use. However, existing technology has certain limitations when processing larger cement blocks, especially in maintaining uniform pressing.

[0003] First, when existing roller presses process larger cement blocks, their pressure distribution may be uneven. This is mainly due to the limitations of the mechanical design and pressure regulation mechanism, which prevents the pressure from being completely and evenly distributed across the surface of the entire cement block. As a result, some parts of the cement block may be crushed by excessive pressure, while other parts may be insufficiently pressed due to insufficient pressure. This uneven pressure distribution may result in inconsistent quality of the final product, affecting its performance in construction or other applications.

[0004] Secondly, the existing equipment is more uneven in crushing when processing harder or irregularly shaped cement blocks. This not only reduces production efficiency but also increases the waste of raw materials. Since the roller press cannot effectively adapt to cement blocks of different hardness or shapes, additional steps or equipment may be required in actual operation to pre-process these cement blocks for more effective flattening.

[0031] In this embodiment, when crushing cement, first put the cement between the two crushing rollers 3, then start the motor 24 to drive the crushing rollers 3 to rotate, and then the two crushing rollers 3 are driven to rotate in the opposite direction through the engagement of the two synchronous wheels 6. Since the two counterweight sleeves 5 have a large weight, they will provide a large inertia, and when encountering a large cement block, it will not have a large impact, thereby ensuring the roller pressing effect.

[0032] See also Figure 2 and Figure 3 As an implementation method of the anti-overload mechanism of a cement roller press: the anti-overload mechanism includes a push rod 10 and a round head 11, a plurality of telescopic grooves 12 are provided on the fixed sleeve 8, each of which is slidably connected to the round head 11, and a slide groove 13 is provided in the fixed sleeve 8, each of which is slidably connected to the push rod 10, a vertical groove 14 is provided on the transmission rod 9, the push rod 10 is respectively pushed in the round head 11 and the vertical groove 14, a spring 15 is provided on the round head 11, the spring 15 is slidably connected in the telescopic groove 12, a threaded sleeve 16 is threaded in each telescopic groove 12, the spring 15 is fixedly connected to the threaded sleeve 16, a plurality of fixed disks 17 are provided on the spring 15, and the plurality of fixed disks 17 are respectively and equidistantly installed on the spring 15, A threaded rod 18 is provided on the inner thread of the threaded sleeve 16, and the threaded rod 18 is threadedly connected to multiple fixed disks 17. A rotating shaft 19 is provided on the transmission rod 9. A fixed plate 20 is sleeved on the rotating shaft 19, and the fixed plate 20 is fitted on the threaded sleeve 16. A limit block 21 is provided on the threaded rod 18. A limit groove 22 is provided on the fixed plate 20. The limit block 21 is clamped in the limit groove 22. A nut 23 is threaded on the limit block 21, and the nut 23 is fitted on the fixed plate 20. A driving mechanism is provided on the support frame 1.

The motor 24 is installed on the support frame 1, and the protruding end of the motor 24 is connected to the driving wheel 25. The belt 26 is respectively engaged with the driving wheel 25 and the driven wheel 7.

[0033] More specifically, when the transmission is in progress, since the driven wheel 7 is fixedly connected to the fixed sleeve 8, the intermediate shaft 4 is fixedly connected to the transmission rod 9, and the push rod 10 is slidably connected in the slide groove 13, the two ends of the push rod 10 are respectively pressed against the round head 11 and the vertical groove 14, and the thrust is applied by the spring 15, so that the two can be engaged with each other. When the transmission force exceeds the thrust of the spring 15, the engagement between the push rod 10 and the vertical groove 14 will be released, thereby preventing overload. When the thrust of the spring 15 needs to be adjusted to move the same position, First, the threaded rod 18 is threadedly connected to different numbers of fixed disks 17, so that the corresponding number of fixed disks 17 can be fixed, so this part of the spring 15 is also fixed. After the length of the spring 15 is changed, the stiffness coefficient will also change.

Therefore, the anti-overload force can be changed, and then the multiple limiting grooves 22 on the fixing plate 20 are clamped on the limiting block 21, so as to fix the threaded rod 18, and limit it by the nut 23, thereby ensuring the fixing effect.

[0034] In summary, when the overall equipment is in use or running: when crushing cement, first put the cement between the two crushing rollers 3, then start the motor 24, thereby driving the rotation of the crushing rollers 3, and then the engagement of the two synchronous wheels 6 will drive the two crushing rollers 3 to rotate in the opposite direction. Since the two counterweight sleeves 5 have a large weight, they will provide a large inertia, and when encountering a large cement block, it will not have a large impact, thereby ensuring the roller pressing effect.

[0035] When transmitting, since the driven wheel 7 is fixedly connected to the fixed sleeve 8, the intermediate shaft 4 is fixedly connected to the transmission rod 9, and the push rod 10 is slidably connected in the slide groove 13, the two ends of the push rod 10 are respectively pressed against the round head 11 and the vertical groove 14, and the thrust is applied by the spring 15, so that the two can be engaged with each other. When the transmission force exceeds the thrust of the spring 15, the engagement between the push rod 10 and the vertical groove 14 will be released, thereby preventing overload. When it is necessary to adjust the thrust of the spring 15 to move the same position, first First, the threaded rod 18 is threadedly connected to different numbers of fixed plates 17, so that the corresponding number of fixed plates 17 can be fixed, so this part of the spring 15 is also fixed. After the length of the spring 15 is changed, the stiffness coefficient will also change. The shorter the length, the greater the stiffness coefficient, and the greater the elastic force generated by moving the same distance. Therefore, the anti-overload force can be changed, and then the multiple limit grooves 22 on the fixed plate 20 are clamped on the limit block 21, so as to fix the threaded rod 18, and limit it by the nut 23, thereby ensuring the fixing effect.
