Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing machines for production, specifically a mixing machine for the production of metallurgical release agents. Background Technology
[0002] Metallurgical release agents are widely used materials in the metal casting and processing industries. They are mainly used to help workpieces be smoothly removed from molds, reducing friction and wear, thereby improving production efficiency and yield. The production of release agents usually requires mixing multiple components in a specific ratio. The ratio of each component directly affects the performance of the release agent (such as flowability, coverage, temperature resistance, etc.). Mechanical mixing and stirring are used to ensure uniform dispersion of components to achieve the required physical and chemical properties. Existing metallurgical release agent mixing machines usually mix the proportioned raw materials after the proportioning is completed. This process is relatively cumbersome and cannot effectively integrate the proportioning and mixing steps, thus affecting production efficiency. Therefore, we propose a mixing machine for the production of metallurgical release agents. Utility Model Content

[0012] (III) Beneficial Effects
[0013] Compared with the prior art, this utility model provides a mixing machine for the production of metallurgical release agents, which has the following beneficial effects:
[0014] 1. This metallurgical release agent production mixing machine, through a tension sensor, can accurately measure the weight of each raw material required for the release agent, thereby achieving high-precision mixing. The sensor can monitor the weight change of each raw material in real time during the mixing process and feed the data back to the control system. The tension sensor has the characteristics of high sensitivity and high precision, which can effectively reduce the error caused by manual operation and ensure that the mixing ratio of each raw material fully meets the preset requirements. During the mixing process, the sensor provides real-time data, allowing operators to make immediate adjustments to ensure consistency in the addition of raw materials and further improve the reliability of the mixing ratio.
[0015] 2. In existing mixing systems for metallurgical release agents, the suspension method often causes the equipment to shake during operation, affecting measurement accuracy and interfering with material loading and unloading. The limiting mechanism effectively restricts the movement range of the hopper, preventing shaking caused by suspension. This design ensures the equipment remains stable during mixing, reducing the impact of external vibrations on measurement accuracy. By setting multiple supports at key parts of the hopper, it maintains greater balance during mixing and is more resistant to displacement caused by external forces. This significantly improves overall stability, ensuring a static state during measurement and greatly reducing dynamic errors caused by material flow or equipment shaking. This improves the measurement accuracy of the tension sensor. In addition, it prevents lateral shaking of the hopper during loading and unloading, making material flow smoother, reducing obstruction, and ensuring that materials can be loaded and unloaded quickly and evenly.
[0016] 3. This metallurgical release agent production mixing machine, through a conveying mechanism, can efficiently transport raw materials from different silos together to meet the diverse proportioning requirements in the metallurgical release agent production process. The conveying mechanism enables continuous conveying of raw materials, avoiding stagnation during production, thus ensuring the smooth and efficient operation of the production line. The closed conveying system effectively prevents materials from being contaminated by the outside during transportation, while reducing material loss caused by exposed openings, ensuring the purity and quality of the raw materials. During the conveying process, different raw materials are fully mixed inside the equipment, avoiding stratification or sedimentation in the silos, making the components more uniform during proportioning and improving the overall performance of the release agent.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 A mixing machine for producing metallurgical release agent includes a support frame 1, a motor 2, and a stirring rod 13. Four support columns are fixedly connected to the four corners of the support frame 1. A top plate is fixedly connected to the top surface of the support columns of the support frame 1. A through hole is opened in the center of the top plate of the support frame 1, and the stirring rod 13 is rotatably connected within the through hole. The motor 2 is fixedly connected to the top plate of the support frame 1. The output shaft of the motor 2 is fixedly connected to the stirring rod 13 through the through hole of the support frame 1. When the motor 2 is started, its output shaft drives the stirring rod 13 to rotate within the through hole of the top plate of the support frame 1. The stirring rod 13 stirs the raw materials, ensuring a more uniform mixture and achieving the desired metallurgical release agent production effect. To meet the physical and chemical requirements for mold release agent production, four symmetrical connection holes are provided around the through hole on the top plate of the support 1. A weighing mechanism is installed on the support 1, and a hopper 6 is installed on the weighing mechanism. A limit mechanism is provided on the hopper 6 to effectively limit the movement range of the hopper and prevent shaking caused by suspension. This design ensures that the equipment remains stable during the proportioning process and reduces the impact of external vibration on measurement accuracy. A conveying mechanism is also provided on the bottom surface of the hopper 6. Through the conveying mechanism, the raw materials in different hoppers can be efficiently transported together to meet the diverse proportioning requirements in the production process of metallurgical mold release agent.
[0024] Furthermore, the feed inlet of the hopper 6 and the stirring rod 13 are coaxially aligned. Connecting seats 7 are symmetrically fixedly connected to the four sides of the hopper 6 near the feed inlet of the hopper 6. Threaded connection holes are provided on the connecting seats 7. Fixing blocks 9 are symmetrically fixedly connected to the four sides of the hopper 6 below the connecting seats 7. Threaded connection holes are provided on the fixing blocks 9.
[0025] Furthermore, the weighing mechanism includes hooks 3, tension sensors 4, connecting screws 5, connecting seats 7, and connecting hooks 16. Hooks 3 are fixedly installed in the four connecting holes of the bracket 1. Threaded holes are symmetrically opened on the upper and lower planes of the tension sensor 4. The connecting hook 16 is rotatably connected to the threaded hole above the tension sensor 4. Hooks 3 and connecting hooks 16 are movably connected. The connecting screw 5 is rotatably connected to the threaded hole below the tension sensor 4. The connecting screw 5 and the threaded connecting hole of the connecting seat 7 are coaxially rotatably connected. The hopper 6 is connected to the tension sensor 4 through the connecting screw 5. The tension sensor 4 is then suspended on the bracket 1 through the connecting hooks 16 and hooks 3. When raw materials are added to the hopper 6, the tension sensor 4 will monitor the weight changes of the hopper 6 and the raw materials in it in real time. Due to the high sensitivity and high precision of the tension sensor 4, it can accurately measure the weight of each raw material required for the release agent and feed the data back to the control system. The operator can accurately control the amount of raw materials added based on the data displayed by the control system to ensure that the ratio of each raw material fully meets the preset requirements.
[0026] Furthermore, the limiting mechanism includes a limiting block 8, a fixing block 9, and a limiting screw 10. The four support columns of the bracket 1 are symmetrically fixedly installed with the limiting blocks 8 on the surfaces facing the fixing blocks 9. The limiting blocks 8 are provided with threaded holes. The threaded connection holes of the fixing blocks 9 are coaxially threadedly connected to the limiting screw 10. The other end of the limiting screw 10 is coaxially threadedly connected to the threaded holes of the limiting blocks 8. The limiting screw 10 connects the fixing blocks 9 and the limiting blocks 8, effectively limiting the movement range of the hopper 6 and preventing shaking caused by the suspension of the hopper 6. This design ensures that the equipment remains stable during the mixing process and reduces the impact of external vibration on the measurement accuracy of the tension sensor 4.
[0027] Furthermore, the conveying mechanism includes a conveying pipe 11, a second motor 12, a discharge port 14, and a spiral conveying blade 15. Two feed pipes are symmetrically fixedly installed on the outer arc surface of the conveying pipe 11, and a discharge port 14 is fixedly installed at the end of the conveying pipe 11. Both the feed pipes and the discharge port 14 of the conveying pipe 11 are connected to the interior of the conveying pipe 11. The spiral conveying blade 15 is coaxially rotatably connected inside the conveying pipe 11. The second motor 12 is fixedly connected to the plane of the bracket 1. The output shaft of the second motor 12 is fixedly connected to the spiral conveying blade 15 through the hole at the end of the conveying pipe 11 where the discharge port 14 is not installed.
[0028] Furthermore, the two feed pipes of the conveying pipe 11 are fixedly connected to the conical barrels at the bottom of the two hoppers 6, respectively. After the raw materials are weighed and proportioned in the hoppers 6, the conveying mechanism is started, and the motor 12 is started. Its output shaft drives the spiral conveying blades 15 inside the conveying pipe 11 to rotate. The two feed pipes of the conveying pipe 11 are fixedly connected to the conical barrels at the bottom of the two hoppers 6, respectively. Under the action of the spiral conveying blades 15, the raw materials in the hoppers 6 are efficiently transported into the conveying pipe 11 through the feed pipes and move towards the discharge port 14. During the conveying process, since the conveying pipe 11 is sealed, it effectively prevents the materials from being contaminated by the outside during the transportation process, and at the same time reduces the material loss caused by the exposure of the opening, ensuring the purity and quality of the raw materials. In addition, different raw materials will be fully mixed in the conveying pipe 11 with the rotation of the spiral conveying blades 15, avoiding the phenomenon of stratification or sedimentation in the hoppers 6, making the components more uniform during proportioning, improving the overall performance of the release agent. Finally, the well mixed raw materials are discharged from the discharge port 14 and enter the subsequent production process.
[0029] Working principle: First, different raw materials are loaded into their respective hoppers 6. Hoppers 6 are connected to tension sensors 4 via connecting screws 5. Tension sensors 4 are then suspended from the bracket 1 via connecting hooks 16 and hooks 3. When raw materials are added to hoppers 6, tension sensors 4 monitor the weight changes of hoppers 6 and the raw materials within them in real time. Due to the high sensitivity and precision of tension sensors 4, they can accurately measure the weight of each raw material required for the release agent and feed the data back to the control system. Based on the data displayed by the control system, the operator precisely controls the amount of raw materials added. To ensure that the proportions of each raw material fully meet the preset requirements, the equipment stability guarantee mechanism plays a crucial stabilizing role during operation. The limiting mechanism connects the fixed block 9 and the limiting block 8 via the limiting screw 10, effectively limiting the movement range of the hopper 6 and preventing swaying caused by the hopper 6 being suspended. This design ensures the overall stability of the equipment during the proportioning process, reducing the impact of external vibrations on the measurement accuracy of the tension sensor 4. When motor 2 starts, its output shaft drives the stirring rod 13 to rotate within the through-hole in the top plate of the support 1. Since the feed inlet of the hopper 6 and the stirring rod 13 are coaxially aligned... The stirring rod 13 stirs the raw materials to ensure a more uniform mixture, achieving the physical and chemical properties required for the production of the metallurgical release agent. This completes the entire production proportioning and mixing process of the metallurgical release agent. After the raw materials are weighed and proportioned in the hopper 6, the conveying mechanism is started. The motor 12 starts, and its output shaft drives the spiral conveying blades 15 inside the conveying pipe 11 to rotate. The two inlet pipes of the conveying pipe 11 are fixedly connected to the conical barrels at the bottom of the two hoppers 6, respectively. Under the action of the spiral conveying blades 15, the raw materials in the hopper 6 are efficiently transported to the conveying mechanism through the inlet pipes. The material moves inside the pipe 11 towards the outlet 14. During the conveying process, the sealed conveying pipe 11 effectively prevents the material from being contaminated by the outside during transportation, while reducing material loss caused by exposed openings. This ensures the purity and quality of the raw materials. Different raw materials are fully mixed inside the conveying pipe 11 as the spiral conveying blades 15 rotate, avoiding stratification or sedimentation in the hopper 6. This makes the components more uniform during mixing, improving the overall performance of the release agent. Finally, the well-mixed raw materials are discharged from the outlet 14 and enter the subsequent production process.
