Description

Technical Field

[0001] This utility model relates to the field of speed calibration technology, specifically to a speed calibration device for a cement mixing mill. Background Technology

[0002] Cement mortar mixing is a test method for inspecting cement quality. It requires mixing cement, standard sand, and water in a ratio of 1:3:0.5 using a mixer to form mortar. The mixer plays a key role in uniformly mixing the materials, and its mixing speed, time, and other parameters affect the quality of the mortar. For example, planetary mixers achieve good mixing results through their unique rotation and revolution trajectories.

[0003] Cement refining mixers have both rotation and revolution. In cement refining and other tests, the correct rotation speed can ensure that cement, standard sand and water are fully and evenly mixed. If the rotation speed is inaccurate, it may lead to uneven mixing of materials. Therefore, it is necessary to calibrate the speed of the mixer.

[0004] Existing calibration methods typically involve two modules: a rotation module and a revolution module. When calibrating the rotation speed, the rotation module is mounted on the planetary disk, and the revolution module is placed around the mixer using a support, aligned with the planetary disk for measurement. However, this method of placing the revolution module around the mixer makes it easy for operators to knock it over during operation, potentially damaging it. Furthermore, vibrations from other equipment, electromagnetic interference, dust stirred up by personnel, and airflow changes can all negatively impact the accuracy of the revolution module's measurements, making it highly susceptible to environmental interference. Additionally, the separate data collection by the rotation and revolution modules results in data asynchrony, significantly affecting the accuracy of the results. Utility Model Content

[0005] This utility model proposes a speed calibration device for a cement soft mixing mixer. It solves the problem that the separate calibration method of two modules in related technologies is easily affected by the surrounding environment and the information data is not synchronized, which affects the accuracy of the measurement. The integrated wireless acquisition module is on the same circuit board, which solves the problem of data synchronization. It is more accurate in calibration and is simple and convenient to install.

[0006] The technical solution of this utility model is as follows: A cement soft mixing mixer speed calibration device is applied on the mixer's revolution shaft, which is provided with a planetary disk and a rotation shaft, and also includes: an integrated wireless acquisition module, tooling installation parts, a computer, a reflective strip, and a light-blocking cloth;

[0007] The integrated wireless acquisition module is installed at the bottom of the planetary disk. The integrated wireless acquisition module consists of a revolution module and a rotation module.

[0008] The reflective strip is provided in two parts, and the two reflective strips are respectively attached to the outside of the mixer's revolution shaft and the rotation shaft;

[0009] The tooling installation component is mounted on the revolution shaft of the mixer, and the integrated wireless acquisition module and the two reflective strips are both installed on the mixer.

[0010] The working principle and beneficial effects of this utility model are as follows:

[0011] 1. In this utility model, the revolution module and the rotation module are on the same circuit board and in the same system, which has the advantage of instantaneous simultaneous acquisition, greatly improving the accuracy of data processing. At the same time, it is easy to install. Simply fix the integrated wireless acquisition module to the planetary disk, and direct the rotation laser on the integrated wireless acquisition module to the reflective strip on the rotation axis, and direct the revolution laser on the integrated wireless acquisition module to the reflective strip attached to the mixer body. It is not easily affected by the surrounding environment, which improves the accuracy of speed calibration, and improves the efficiency and effect of speed calibration.

[0012] 2. In this utility model, the protective mechanism facilitates the protection of the integrated wireless acquisition module, effectively preventing cement from being thrown onto the integrated wireless acquisition module or reflective strip by the high-speed rotating mixing rod, thereby improving the efficiency and effectiveness of speed calibration.

Two reflective strips 7 are provided, and the two reflective strips 7 are respectively attached to the mixer body 1 and the rotation shaft 3. The protective shell 8 is installed on the mixer body 1. The integrated wireless acquisition module 4 and the two reflective strips 7 are mounted on the bottom of the planetary disk 2. Each reflective strip 7 is housed within the protective casing 8. The revolution module 5 and the rotation module 6 are on the same circuit board and within the same system, offering the advantage of simultaneous instantaneous data acquisition. This significantly improves the accuracy of data processing and also ensures convenient installation. Simply fix the integrated wireless acquisition module 4 onto the planetary disk 2, and direct the rotation laser from the integrated wireless acquisition module 4 onto the reflective strip on the rotation shaft 3. The revolution laser from the integrated wireless acquisition module 4 also directs the laser from the revolution module 4 onto the reflective strip attached to the mixer body 1. This design is less susceptible to environmental influences, improving the accuracy, efficiency, and effectiveness of speed calibration.

[0021] The tooling installation component is set on the planetary disk 2 for installing the integrated wireless acquisition module 4. The tooling installation component includes a connecting plate 9 and a mounting plate 10. There are two connecting plates 9, which are installed at the bottom of the planetary disk 2. The mounting plate 10 is fixedly connected to each of the two connecting plates 9. The integrated wireless acquisition module 4 is installed between the two mounting plates 10. Specifically, the connecting plates 9 are stably installed on the planetary disk 2, which can stably support the two mounting plates 10, thereby improving the stability of the integrated wireless acquisition module 4 installed between the two mounting plates 10.

[0022] The protective mechanism, installed on the protective shell 8, is used to block cement splashes. The protective mechanism includes a rotating plate 11, connecting rods 12, and a cleaning assembly. Two limiting rings 18 are fixedly connected to the rotating plate 11, each contacting the inner and outer walls of the protective shell 8 respectively. The protective shell 8 has a rotating opening, and the rotating plate 11 is rotatably connected within this opening. A rotation shaft 3 is located within the rotating opening. Connecting rods 12 are fixedly connected to both connecting plates 9, and the bottom ends of both connecting rods 12 are connected to… The rotating plate 11 is fixedly connected. The cleaning assembly is set on the protective shell 8 and is used to clean the surface of the protective shell 8. The cleaning assembly includes: a toothed ring 13, a cleaning frame 14, and a drive assembly. The toothed ring 13 is rotatably connected to the circumferential surface of the protective shell 8. There are two cleaning frames 14, both of which are fixedly connected to the toothed ring 13 and are in contact with the surface of the protective shell 8.

Rotation speed calibration can be performed when the planetary disk 2 and the spin shaft 3 rotate. When the spin shaft 3 and the planetary disk 2 rotate, the rotating plate 1... 1. Through the connection of the connecting rod 12, it can rotate synchronously with the planetary disk 2. When the cement is thrown out by the high-speed rotating shaft 3, the protective shell 8 can block the cement. When it is necessary to observe the internal situation through the protective shell 8, the first motor 17 set on the fixed frame 15 drives the drive gear 16 to rotate. When the drive gear 16 rotates, it drives the gear ring 13 and the two cleaning frames 14 to rotate, thereby scraping off the cement adhering to the protective shell 8, making it convenient for the operator to observe the internal situation of the protective shell 8 through the protective shell 8.
