Description

Technical Field

[0001] The invention relates to the technical field of stirring devices, in particular to a mineral casting batching device. Background Art

[0002] Batching devices play a vital role in the production process of mineral castings. These devices are used to accurately proportion various mineral raw materials according to specific formulas to ensure that the castings have the required physical and chemical properties. In the background technology, the main task of the mineral casting batching device is to achieve accurate proportioning and stable transportation of raw materials to support the production process of high-quality castings. Traditional batching technology relies on manual operation or simple automation systems. These methods often have problems such as insufficient batching accuracy, low operating efficiency, and material waste. With the development of industrial automation technology, new batching devices use advanced sensors, automatic control systems and precision weighing equipment to significantly improve the accuracy and production efficiency of batching. Modern batching devices can achieve continuous and accurate material transportation and mixing, and can be adjusted in real time according to production needs. These advanced batching systems usually include vibrating feeders, automatic weighing equipment, control systems and data monitoring systems. Vibrating feeders prevent material blockage and waste by evenly conveying mineral raw materials; automatic weighing equipment ensures the accurate proportion of various raw materials; control systems and data monitoring systems realize real-time monitoring and adjustment of the batching process to ensure the stability and consistency of the batching. The mineral casting batching device using these technologies not only improves production efficiency, but also ensures the high quality and consistency of castings, laying a solid foundation for the industrial production of mineral castings; There are still the following defects in specific use: 1. Vibration may cause fatigue cracks inside the casting. These cracks usually start from the surface of the casting. As the vibration cycle increases, the cracks will gradually expand, and may eventually cause the casting to rupture or fail. At the same time, the repetitive stress generated by vibration will cause the casting material to bear constantly changing loads, leading to the formation and expansion of internal microcracks. Long-term vibration will cause changes in the microstructure of the material, such as relaxation of the grain interface or weakening of the bonding force between atoms, thereby affecting the mechanical properties and overall strength of the casting. Vibration may weaken the internal structure of the casting and reduce its bearing capacity.

[0003] 2. In addition, cracks and deformations lead to uneven distribution of the bearing capacity of the casting material, which may cause early failure in areas with greater loads. Secondly, crack propagation will gradually weaken the overall structure of the casting, causing the crack to develop from a local problem to a comprehensive failure. In addition, the internal stress changes caused by vibration will produce uneven stress distribution on the casting surface, thereby affecting the surface quality.

At the same time, the friction cancellation mechanism can help the casting maintain a more stable movement on the vibration platform, reducing the offset and accumulation problems. The friction cancellation mechanism reduces the efficiency of vibration transmission by reducing the friction during the vibration process, thereby protecting the mineral casting from or less affected by the vibration.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1As shown, the operator starts the motor 13, and the motor 13 drives the vibrating feeder 1 to vibrate. Secondly, through the vibration of the vibrating feeder 1, the material is evenly distributed on the vibrating platform 11. In addition, the vibrating platform 11 is usually equipped with a screen. Through vibration, larger particles of material are screened out, while smaller particles fall into the downstream equipment through the screen. Finally, the mineral castings poured onto the surface of the vibrating platform 11 evenly enter the inside of the vibrating platform 11 from the surface of the vibrating platform 11 and then flow out, ensuring a stable feeding flow rate; When using: The friction cancellation mechanism reduces the friction during vibration to reduce the efficiency of vibration transmission. 2 steps: like Figure 3 to Figure 4 As shown, when the mineral casting falls onto the surface of the vibration platform 11, the operator first starts the reduction motor connected to the output end of the drive shaft 22, and then the start of the reduction motor drives the bidirectional screw 211 to rotate, and then the rotation of the bidirectional screw 211 causes the left buckle 23 and the right buckle 25, which form a ball screw structure with the outer wall, to move horizontally toward each other. Furthermore, the built-in drive motor of the fixed shaft 28, when started, drives the fixed shaft 28 to rotate, so that during the process of the left buckle 23 and the right buckle 25 moving horizontally toward each other, the ends of the left buckle 23 and the right buckle 25 away from the bidirectional screw 211 will move synchronously. The two friction wheels 24 and 26 are moved horizontally toward each other on the fixed shaft 28, thereby driving the left friction wheel 24 and the right friction wheel 26, which are threadedly connected to the outer wall of the fixed shaft 28, to rotate and move horizontally toward each other. As a result, during the rotation and horizontal displacement of the left friction wheel 24 and the right friction wheel 26, the two friction discs 210 that are in contact with the surfaces thereof will rotate relative to each other, so that the surface of the mineral casting that falls on the vibration platform 11 will contact the outer wall of the friction disc 210, and then as the friction disc 210 rotates, mutual friction will be generated therewith, thereby evenly dispersing and offsetting the friction force between the mineral casting and the surface of the vibration platform 11; Stress relief mechanism for flipping mineral castings to redistribute internal stress in castings in different directions 3 steps: like Figures 5 and 6As shown, when the friction disc 210 rotates, the transverse bevel gear 31 fixedly connected to the outer wall of one end of the friction disc 210 near the frame rod 29 will rotate together, so that the longitudinal bevel gear 32 that meshes with it and forms a meshing transmission will rotate together with the rotation of the transverse bevel gear 31, and then the camshaft 33 fixedly connected to the lower end of the longitudinal bevel gear 32 will rotate synchronously with the rotation of the longitudinal bevel gear 32, and at the same time, the outer shaft 34 fixedly connected to the lower end of the camshaft 33 will also rotate synchronously with the rotation of the longitudinal bevel gear 32, so that the rotation of the outer shaft 34 will drive the wedge block 36 that meshes with the half teeth set on the upper surface of the outer shaft 34 and forms a meshing transmission to rotate, so the rotation of the wedge block 36 will cause the wedge block 36 fixedly connected at one end The shovel plate 38 is turned over and rotated, and the turning and rotation of the shovel plate 38 realizes the lateral turning over of the mineral casting that falls on the surface of the vibration platform 11. In addition, as the camshaft 33 rotates until the convex portion provided on the outer wall of one side of the camshaft 33 contacts the concave-convex surface provided on the top of the wedge block 36 away from the ring gear 35, the convex portion provided on the outer wall of one side of the camshaft 33 will press the concave-convex surface provided on the top of the wedge block 36 away from the ring gear 35 downward due to the rotation, thereby causing the wedge block 36 to deflect clockwise on the outer wall of one side of the external plate 37. The clockwise deflection of the wedge block 36 will pull the shovel plate 38 fixedly connected to one end of the wedge block 36 to deflect downward, so that the downward deflection of the shovel plate 38 realizes the longitudinal turning over of the mineral casting that falls on the surface of the vibration platform 11. The axial toggle mechanism ensures that the vibration energy is evenly transmitted inside the mineral casting, eliminates and reduces the possible vibration dead angles of the mineral casting during the vibration process. 4 steps: like Figures 7 and 8 As shown, when the shovel plate 38 is turned over and rotated, the eccentric wheel 41 fixedly connected to the outer wall of one end of the shovel plate 38 close to the wedge block 36 will also rotate. In this way, when the eccentric wheel 41 rotates until the convex shape provided on the outer wall of the eccentric wheel 41 abuts against the convex surface provided on the top outer wall of the rotating block 45 close to the rotating disk 42, the rotating block 45 will deflect to the side away from the rotating disk 42. At the same time, the deflection of the rotating block 45 will cause the tip part provided on the outer wall of the bottom end of the rotating block 45 close to the rotating disk 42 to disengage from the arc-shaped recess provided on the outer wall of the rotating disk 42, and will push the rotating disk 42 to rotate. In this way, the rotation of the rotating disk 42 will cause the synchronous belt 43 connected to one end of the rotating disk 42 to be driven, thereby rotating the sweeping handle 44 fixedly connected to the outer wall of the synchronous belt 43 away from the rotating disk 42. The burrs, oxide scales and other defects on the surface of the casting are removed by the rotation of the sweeping handle 44, thereby improving the surface finish and roughness of the casting. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
