[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 This utility model provides a technical solution for an automatic control device for sintering batching and mixing:
[0029] like Figure 4 and Figure 5As shown, the system includes a hopper 1. Four connecting blocks are welded to the outside of the hopper 1. High-precision weighing sensors 2 are bolted to the bottom of each of the four connecting blocks. A support frame is bolted to the bottom of each weighing sensor 2. The weight of the raw materials inside the hopper 1 is collected in real time by the weighing sensors 2. The signals from the weighing sensors 2 are transmitted to a PLC 3 via cables to ensure a weighing accuracy of no less than ±0.1%, achieving high-precision raw material measurement. The weighing sensors 2 are electrically connected to the programmable logic controller (PLC 3). A discharge hole is opened on the bottom of the hopper 1. Two sliding holes are opened on the side of the hopper 1. A slider 4 is slidably connected to one side of each of the two sliding holes. A slide rail 5 is bolted to the inner cavity of the hopper 1. The slide rail 5 is located on one side of the sliding hole and slidably connected to the slider 4. Several blocks are bolted to the outside of the hopper 1. Two of these blocks have a slide rail 6 fixedly connected to one side. The slide rail 5 is bolted to the inner cavity of the hopper 1 to constrain the movement direction of the slider 4. The slide rail 6 is fixed to the outer blocks of the hopper 1. For the linear movement of the guide plate and the moving plate 8, the slide rail 1 5 and the slide rail 2 6 cooperate with each other to ensure the smooth and stable movement of the slider 4 and the moving plate 8 without shaking, thereby improving the reliability of the opening and closing mechanism. A long plate is fixedly connected to one side of the slide rail 2 6, and a micro telescopic motor 7 is bolted to one side of the long plate. The output end of the micro telescopic motor 7 passes through the outside of the long plate and connects to the moving plate 8. The PLC3 drives the micro telescopic motor 7 to extend and retract, thereby driving the moving plate 8 to move linearly. The moving plate 8 pulls the slide rod 9 and push plate 10 to move together, pushing the slider 4 to open / close the feeding hole, thereby achieving precise control of the quantitative feeding of raw materials. Two slide rods 9 are fixedly installed on one side of the moving plate 8. One end of the two slide rods 9 passes through the outside of the block and connects to the push plate 10. Two clamps 11 are bolted to one side of the push plate 10. One side of the two clamps 11 is bolted to the slider 4. The PLC3 controls the micro telescopic motor 7 on the corresponding hopper 1 through the drive signal to control the opening / closing of the feeding hole of the raw materials.
[0030] like Figure 3 As shown, the bottom surface of the hopper 1 is bolted to the mixing tank cover 12. The top surface of the mixing tank cover 12 has a feed hole with the same diameter as the feed hole of the hopper 1. The feed hole of the hopper 1 is the same as the feed groove of the mixing tank cover 12. Holes are opened on both sides of the feed groove of the cover 12. A guide plate 18 is fixedly connected to one side of the hole. A triangular plate is bolted to the bottom and top surface of the feed groove of the cover 12. The raw material of the hopper 1 falls into the feed groove of the cover 12. The raw material rolls out of the hole of the feed groove from the triangular plate. When the slider 4 opens the feed hole, the raw material falls into the feed groove through the feed hole. The triangular plate and the guide plate 18 cooperate to guide the material to roll out of the hole smoothly into the mixing tank, preventing material blockage and improving feeding efficiency.
[0031] like Figure 3As shown, the bottom surface of the cover 12 is bolted to the box body, and the outer side of the box body is bolted to the fixing block. A rotary motor 13 is bolted to one side of the fixing block. The output end of the rotary motor 13 passes through the outer side of the fixing block and connects to the box body. The output end of the rotary motor 13 passes through the outer side of the box body and connects to gear one. Gear two meshes with one side of gear one. A rotating shaft is fixedly connected to the bottom surface of gear two. Several stirring fans 14 are bolted to the outer side of the rotating shaft. The gear transmission, in conjunction with the rotary motor 13 and the stirring fans 14, achieves low-speed start-up, high torque, and high efficiency. The system features rapid mixing to meet the mixing needs of different materials, and speed optimization is achieved through frequency conversion speed regulation. A connecting frame is bolted to the top and bottom surfaces of the inner cavity of the housing. The output end of the rotary motor 13 is connected through the connecting frame from the top surfaces of several mixing fans 14. A discharge chamber 15 is fixedly connected to the bottom surface of the housing, and a discharge hole is provided on the bottom surface of the discharge chamber 15. The rotary motor 13 of the housing cover 12 is electrically connected to the PLC 3. According to the preset formula parameters, the PLC 3 sequentially starts the output end of the micro telescopic motor 7 to push the moving plate 8 and the slider 4, and collects data in real time. Based on the signal from the weighing sensor 2, when the weight of any raw material reaches the preset value, the PLC3 automatically pulls the moving plate 8 at the output end of the micro telescopic motor 7 to block the material discharge by the slider 4. After all raw materials are dispensed, the PLC3 starts the rotary motor 13 to mix the materials. After the preset mixing time is reached or the online mixing uniformity sensor 17 detects that the mixing uniformity meets the requirements, the PLC3 stops mixing. After mixing is completed, the PLC3 controls the discharge door to open to complete the discharge. According to the preset formula parameters, the PLC3 starts each micro telescopic motor 7 in sequence to drive the corresponding slider 4 to open and close the discharge hole. When the weighing sensor 2 detects the target weight, the discharge hole is immediately closed to complete the dispensing. After all raw materials are dispensed, the PLC3 starts the rotary motor 13 to drive the stirring fan 14 to mix. The online mixing uniformity sensor 17 provides real-time feedback on the mixing uniformity. The PLC3 dynamically adjusts the mixing time and speed to ensure the mixing quality. After the preset mixing time or uniformity standard is reached, the PLC3 stops the rotary motor 13 and controls the discharge chamber 15 to open the discharge door to complete the discharge.
[0032] like Figure 2 As shown, the weighing accuracy of the weighing sensor 2 is not less than ±0.1%.
[0033] like Figure 2 As shown, the PLC3 is equipped with a touch screen module 16, which is used to input formula parameters, set mixing time, and display real-time production status. The touch screen module 16 is used to input formula parameters, set mixing time, and display operating status. The network interface enables remote monitoring of production data and query of historical records, and supports remote adjustment and maintenance.
[0034] like Figure 3 As shown, the rotary motor 13 is an adjustable speed variable frequency motor.
[0035] like Figure 2 As shown, the output signal of the online mixing uniformity sensor 17 can be evaluated by the PLC3, and the stirring time or stirring speed can be dynamically adjusted.
[0036] like Figure 1 As shown, PLC3 communicates with the host computer system through a network interface to achieve remote monitoring and data recording.
[0037] like Figure 3 and Figure 4 As shown, it also includes a fault diagnosis module, which is used to monitor the operating status of the weighing sensor 2, the miniature telescopic motor 7 and the rotary motor 13 in real time, and to issue an alarm signal or control the PLC3 to perform shutdown protection when an abnormality is detected. The fault diagnosis module monitors the status of key components in real time, and when an abnormality is detected, it issues an alarm signal to the PLC3 and triggers shutdown protection to prevent equipment damage and personal injury.
[0038] like Figure 1 As shown, the components of the device are connected via a standard industrial bus protocol to improve system compatibility and scalability. The combination of the standard bus protocol and modular design enhances system compatibility and scalability, facilitating subsequent equipment expansion and upgrades.
[0039] The working principle of this utility model is as follows: First, PLC3 sends control signals to each micro telescopic motor 7 according to the formula parameters input by the user on the touch screen module 16. Each micro telescopic motor 7 drives the moving plate 8 to drive the slider 4 to open the feeding hole of the hopper 1. The raw materials are introduced into the mixing tank cover 12 through the feeding trough and the triangular plate and guide plate 18 structure. At the same time, the weighing sensor 2 collects the weight in the hopper 1 in real time. When the weight reaches the preset value, PLC3 sends a signal to pull back the moving plate 8 of the micro telescopic motor 7 and push the slider 4 to close the feeding hole, thus completing the feeding of the hopper 1. Second, after all the hoppers 1 have completed feeding, PLC3 starts the rotary motor 13, which drives the mixing fan 14 to rotate and mix the materials in the tank through the transmission of gear one and gear two. The online mixing uniformity sensor 17 monitors the mixing state of the materials in real time and feeds the data back to PLC3. PLC3 dynamically adjusts the speed and stirring time of rotary motor 13 based on feedback to ensure that the mixing uniformity meets the process requirements. Finally, when the set mixing time is reached or the online sensor detects that the uniformity is qualified, PLC3 stops the operation of rotary motor 13, controls the discharge chamber 15 to open the discharge door, and the material is discharged from the discharge hole. The fault diagnosis module continuously monitors the status of each key component. After ensuring that there are no abnormalities, the current batching and mixing cycle ends, and the system enters standby mode to prepare for the next start-up.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
