Description

Technical Field

[0001] This invention relates to the field of vibratory feeding technology in steel production, and in particular to a control system for reducing belt stall in a feeding system. Background Technology

[0002] Vibration unloading in steel production typically involves the handling and transportation of raw materials. In steel production, raw materials such as iron ore and coke are usually stored in the stockyard. To facilitate loading, vibration unloading equipment helps ensure the smooth transportation of raw materials on the production line, improves production efficiency, and reduces potential production interruptions.

[0003] Currently, in steel production, to ensure that the materials entering the production furnace have as few impurities as possible, it is necessary to use vibration during feeding. The vibration during operation will separate impurities from the production materials, thus facilitating subsequent screening. This vibration method uses an electric motor to drive a pulley to rotate. Two pulleys are set up, and the cooperation between the two pulleys drives the drive shaft to rotate. The drive shaft runs through the interior of the feeding machine, and a cam is fixed on its surface. The cam rotates and continuously taps the surface of the feeding machine, thereby generating vibration.

[0004] In current technologies, the feeding process, which uses a cam to vibrate the surface of the feeder, is often hampered by the confined space and compact installation of the equipment. This can lead to belt blockage during vibratory feeding or unloading, causing material buildup on the feeder's surface. If not stopped promptly, the blockage worsens, eventually trapping material on the feeder's surface. Consequently, the cam can no longer rotate, which in turn prevents the connected drive shaft and pulley from turning. At this point, the motor remains operational, pulling on the belt and causing significant damage to the belt, motor, and other components, severely impacting the equipment's lifespan. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this invention is to overcome the fact that the internal space of the feeding machine is relatively small and the equipment is installed in a compact manner. When vibrating to feed or unload, the belt is prone to jamming, which leads to material blockage on the surface of the feeding machine. If not stopped in time, the blockage will become more and more serious, causing the material to get stuck on the surface of the feeding machine. This prevents the cam from rotating and also prevents the connected drive shaft and pulley from rotating. At this time, the motor is still working and begins to pull the belt, which causes great damage to the belt, motor and other equipment, and seriously affects the service life of the equipment.

[0006] To solve the above-mentioned technical problems, the present invention provides a control system for reducing belt stall in a feeding system, comprising:

[0013] The power supply voltage detection module is used to detect power supply voltage fluctuations.

[0014] The line resistance detection module is used to detect changes in resistance in the line.

[0015] When the current detection module detects an abnormality, the PLC processing module transmits a signal indicating excessive current to the computer and simultaneously controls the motor to stop working.

[0016] In one embodiment of the present invention, a support base is fixedly connected to the bottom of the control cabinet; support brackets are fixedly connected to both sides of the top of the support base; a damper is fixedly connected to the top of the support bracket; a connecting bracket is fixedly connected to the top of the damper; a vibrating conveyor box is fixedly connected to the surface of the connecting bracket; and vibrating pulleys are rotatably connected to both sides of the vibrating conveyor box via a drive shaft.

[0017] In one embodiment of the present invention, the number of vibrating pulleys is set to two, and the surfaces of the two vibrating pulleys are connected to a drive pulley via a belt drive; a placement platform and a rotating support platform are fixedly connected to both sides of the support base; the top of the placement platform is fixedly connected to the surface of the motor; a rotating shaft is rotatably connected to the surface of the rotating support platform; the output shaft of the motor is fixedly connected to one end of the rotating shaft via a coupling; the number of drive pulleys is set to two, and the center of the shaft of each of the two drive pulleys is fixedly connected to the surface of the rotating shaft.

[0018] In one embodiment of the present invention, a hopper is fixedly connected to the top of one side of the vibrating conveyor box; a vibrating plate is fixedly connected to the inner wall of the vibrating conveyor box; and a vibrating screen plate is fixedly connected to the surface of the vibrating plate.

[0019] In one embodiment of the present invention, the surface of the vibrating conveyor box is provided with a material unloading assembly; the material unloading assembly includes a rotating frame; a supporting rotating rod is rotatably connected to the surface of the rotating frame; and a material unloading roller is fixedly connected to the surface of the supporting rotating rod.

[0020] In one embodiment of the present invention, both ends of the support rod pass through the rotating frame and extend to both sides of the rotating frame; both ends of the support rod are fixedly connected to a transmission pulley; the number of transmission pulleys is set to multiple, and the surfaces of the multiple transmission pulleys are connected by a belt in an alternating transmission manner.

[0021] In one embodiment of the present invention, an upper motor is fixedly connected to the surface of the hopper; the output shaft of the upper motor is fixedly connected to an upper pulley via a coupling; the surface of the upper pulley is connected to the surface of one of the transmission pulleys via a belt.

[0022] In one embodiment of the present invention, an auxiliary pulley is connected to the surface of the transmission pulley via a belt drive; a reciprocating lead screw is fixedly connected to the surface of the auxiliary pulley.

[0023] In one embodiment of the present invention, one end of the reciprocating screw passes through the vibrating conveyor box and extends into the interior of the vibrating conveyor box; a feeding plate is slidably connected to the surface of the reciprocating screw located inside the vibrating conveyor box.

[0025] The technical solution of the present invention has the following advantages compared with the prior art:

[0026] The present invention discloses a control system for reducing belt stall in a feeding system. This system uses a current detector to monitor the motor's operating current in real time and transmits the current signal to a PLC processing module. When an abnormality occurs in the operating current, the current detection module checks the motor current during feeding to see if it exceeds a reasonable fluctuation range. Simultaneously, to mitigate other influencing factors, a power supply voltage detection module detects power supply voltage fluctuations, and a line resistance detection module detects changes in line resistance. When the voltage and resistance are normal, but the operating current is greater than or equal to 1.1 times the normal current, it indicates a high load, suggesting the belt is about to stall. At this point, the PLC processing module controls the motor to stop working, and subsequent load maintenance is performed. After maintenance is completed, the motor is restarted, thus avoiding significant damage to the belt, motor, and other equipment, and ensuring the equipment's lifespan.

[0027] The present invention discloses a control system for reducing belt blockage in a feeding system. By setting an upper motor, when the motor stops due to detection, the upper motor starts working, driving the upper pulley to rotate. The upper pulley, in conjunction with the transmission pulley, drives the support rod to rotate in the opposite direction to the feeding direction. The support rod drives the unblocking roller to back the blocked material. The transmission pulley, in conjunction with the auxiliary pulley, drives the reciprocating screw to rotate, which in turn drives the unblocking plate to move back and forth, clearing the blocked material. This reduces the load during feeding, facilitates subsequent feeding, and improves the adaptability of the feeding operation. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0038] Reference Figure 1-7 As shown, a control system for reducing belt stall in a feeding system according to the present invention includes:

[0039] The PLC processing module, current detection module, power supply voltage detection module, and line resistance detection module are installed inside control cabinet 1.

[0040] A computer electrically connected to the PLC processing module;

[0041] A current detector connected in series between motor 11 and the PLC processing module;

[0042] Its features are:

[0043] The current detector is used to transmit the collected current to the PLC processing module;

[0044] The current detection module is used to detect the current of motor 11 during the feeding process;

[0045] The power supply voltage detection module is used to detect power supply voltage fluctuations.

[0046] The line resistance detection module is used to detect changes in resistance in the line.

[0047] When the current detection module detects an abnormality, the PLC processing module transmits a signal indicating excessive current to the computer and simultaneously controls the motor 11 to stop working.

[0048] The control system for reducing belt stall in the feeding system provided by this invention has a current detector connected in series between the motor 11 and the PLC processing module. The PLC processing module, along with the current detection module, power supply voltage detection module, and line resistance detection module, are installed inside the control cabinet 1. The PLC processing module is electrically connected to a computer. The current detector transmits the collected current to the PLC processing module. The current detection module then monitors the current of the motor 11 during the feeding process, the power supply voltage detection module detects power supply voltage fluctuations, and the line resistance detection module detects changes in resistance in the circuit. This detects the three factors affecting the current magnitude, avoiding the influence of voltage and resistance on the current. Therefore, the system only detects when the current magnitude exceeds the specified limit. The problem is that when the current of motor 11 is greater than or equal to 1.1 times the normal current, it can be determined that the load is too high, and the belt is about to stall. The PLC processing module controls motor 11 to stop working, and then load maintenance is performed. After the maintenance is completed, motor 11 is restarted. During this process, the computer and PLC processing module are electrically connected, and a stall alarm message will appear on the computer's monitoring screen. Afterwards, the stall current is constantly monitored and optimized until belt stalling is completely eliminated. Compared with existing technologies, this can immediately stop motor 11, avoiding the situation where the blockage will become more and more serious during material feeding, thereby avoiding greater damage to the belt, motor 11 and other equipment, and ensuring the service life of the equipment.

[0049] like Figure 2-5 As shown, in one embodiment of the present invention, a support base 2 is fixedly connected to the bottom of the control cabinet 1; support brackets 3 are fixedly connected to both sides of the top of the support base 2; a damper 4 is fixedly connected to the top of the support bracket 3; a connecting seat 5 is fixedly connected to the top of the damper 4; a vibrating conveyor box 6 is fixedly connected to the surface of the connecting seat 5; vibrating pulleys 7 are rotatably connected to both sides of the vibrating conveyor box 6 via a drive shaft; the number of vibrating pulleys 7 is set to two, and the surfaces of the two vibrating pulleys 7 are connected to a drive pulley 8 via a belt drive; the support base 2 is fixedly connected to both sides of the support base 2. A placement platform 9 and a rotating support platform 10 are fixedly connected; the top of the placement platform 9 is fixedly connected to the surface of the motor 11; a rotating shaft 12 is rotatably connected to the surface of the rotating support platform 10; the output shaft of the motor 11 is fixedly connected to one end of the rotating shaft 12 via a coupling; two drive pulleys 8 are provided, and the shaft centers of both drive pulleys 8 are fixedly connected to the surface of the rotating shaft 12; a feed hopper 13 is fixedly connected to the top of one side of the vibrating conveyor box 6; a vibrating plate 14 is fixedly connected to the inner wall of the vibrating conveyor box 6; a vibrating screen plate 15 is fixedly connected to the surface of the vibrating plate 14.

[0050] When the vibrating conveyor 6 provided by this invention is in operation, the control cabinet 1 is first supported by the support base 2, the support platform 3 and the placement platform 9 are supported by the support base 2, and the top of the support platform 3 supports the damper 4. The top of the damper 4 is fixedly connected to the bracket 5, and the vibrating conveyor 6 is fixed on the connecting bracket 5. The damper 4 buffers and reduces the vibration of the vibrating conveyor 6. The placement platform 9 is used to support the motor 11. When the motor 11 is working, it drives the drive pulley 8 to start rotating through the output shaft. There are two drive pulleys 8, which are connected by the rotating shaft 12 to make the two drive pulleys 8 rotate together. Then, the belt drives the two vibrating pulleys 7 to start rotating. The vibrating pulleys 7 cooperate with the transmission shaft to make the vibrating conveyor 6 start vibrating. In particular, when vibrating, a cam needs to be fixed on the surface of the transmission shaft inside the vibrating conveyor 6 so that the cam continuously hits the vibrating plate 14, thereby driving the vibrating screen plate 15 to start vibrating together, so as to realize the function of vibrating feeding.

[0051] like Figure 5-7 As shown, in one embodiment of the present invention, the surface of the vibrating conveyor box 6 is provided with a material unloading assembly; the material unloading assembly includes a rotating frame 16; a supporting rotating rod 17 is rotatably connected to the surface of the rotating frame 16; a material unloading roller 18 is fixedly connected to the surface of the supporting rotating rod 17; both ends of the supporting rotating rod 17 pass through the rotating frame 16 and extend to both sides of the rotating frame 16; both ends of the supporting rotating rod 17 are fixedly connected to transmission pulleys 19; the number of transmission pulleys 19 is set to multiple, and the surfaces of the multiple transmission pulleys 19 are connected by interleaved transmission belts; an upper-mounted motor 20 is fixedly connected to the surface of the hopper 13; the output shaft of the upper-mounted motor 20 is fixed by a coupling. An upper pulley 21 is connected; the surface of the upper pulley 21 is connected to the surface of one of the transmission pulleys 19 via a belt; the surface of the transmission pulley 19 is connected to an auxiliary pulley 22 via a belt; a reciprocating screw 23 is fixedly connected to the surface of the auxiliary pulley 22; one end of the reciprocating screw 23 passes through the vibrating conveyor 6 and extends into the interior of the vibrating conveyor 6; a material unloading plate 24 is slidably connected to the surface of the reciprocating screw 23 inside the vibrating conveyor 6; the surface of the reciprocating screw 23 is fixedly connected to the surface of the vibrating conveyor 6; a limiting slide rod 25 is fixedly connected to the inner wall of the vibrating conveyor 6; the surface of the material unloading plate 24 is slidably connected to the surface of the limiting slide rod 25.

[0052] When the material unloading assembly provided by this invention is in operation, a rotating frame 16 is first set up and fixed on the top surface of the vibrating conveyor box 6. The support rotating rod 17 can rotate on the rotating frame 16. During unloading, it is necessary to wait until the motor 11 detects an emergency stop, and then the upper motor 20 starts working, driving the upper pulley 21 to start rotating. The upper pulley 21, in conjunction with the transmission pulley 19, drives the support rotating rod 17 to rotate in the opposite direction to the material feeding direction. The support rotating rod 17 drives the unloading roller 18 to back the blocked material. Multiple transmission pulleys 19 are set up, and each transmission pulley 19 is connected by belts. This causes multiple drive pulleys 19 to rotate together, which in turn drives the support rotating rod 17 and the material unloading roller 18 to rotate together, unloading material at multiple positions on the vibrating screen plate 15 simultaneously. In addition, the last spare drive pulley 19 is connected to the auxiliary pulley 22 via a belt, which drives the reciprocating screw 23 to start rotating, thereby driving the material unloading plate 24 to move back and forth to clear the blocked material. At the same time, the limiting slide rod 25 limits the material unloading plate 24 to ensure normal material unloading, thereby reducing the load during feeding, facilitating subsequent feeding, and improving the adaptability of feeding work.

[0053] Working Principle: In current technologies where material is fed by vibrating the surface of a feeder using a cam, the internal space of the feeder is relatively small and the equipment is tightly installed. This can easily lead to belt blockage during vibratory feeding or unloading, causing material to accumulate on the feeder surface. If not stopped promptly, the blockage worsens, eventually trapping material on the feeder surface. This prevents the cam from rotating further, consequently stopping the connected drive shaft and pulley. Meanwhile, the motor remains running, pulling on the belt, causing significant damage to the belt, motor, and other components, severely impacting the equipment's lifespan. The control system for reducing belt blockage in the feeding system provided by this invention uses a current detector connected in series during operation. Between motor 11 and the PLC processing module, the PLC processing module, along with the current detection module, power supply voltage detection module, and line resistance detection module, are installed inside control cabinet 1. The PLC processing module is electrically connected to the computer. The current detector transmits the collected current to the PLC processing module. The current detection module then monitors the current of motor 11 during the feeding process. The power supply voltage detection module detects power supply voltage fluctuations, and the line resistance detection module detects changes in resistance in the circuit. This detects the three factors affecting the current magnitude and mitigates the influence of voltage and resistance on the current. Therefore, only when the current magnitude is problematic—that is, when the motor 11 current is greater than or equal to 1.1 times the normal current—can it be determined that the load is too high. If the belt is about to stall, the PLC processing module controls the motor 11 to stop working, followed by load maintenance. After maintenance is completed, the motor 11 is restarted. During this process, the computer and PLC processing module are electrically connected, and a stall alarm message appears on the computer's monitoring screen. The stall current is then continuously monitored and optimized until belt stalling is completely eliminated. Compared to existing technologies, this allows for immediate emergency stopping of the motor 11, preventing the stall from worsening during feeding and thus avoiding significant damage to the belt, motor 11, and other equipment, ensuring the equipment's lifespan. In operation, the vibrating conveyor 6 provided by this invention is first supported by the support base 2, which supports the control cabinet 1, the support platform 3, and the placement platform 9. The support platform 3 is topped with... A damper 4 is supported, with a connecting bracket 5 fixed to its top. The vibrating conveyor box 6 is fixed on the connecting bracket 5. The damper 4 buffers and reduces vibration in the vibrating conveyor box 6. A platform 9 supports the motor 11. When the motor 11 is working, it drives the drive pulley 8 to rotate via its output shaft. Two drive pulleys 8 are provided and cooperate with the rotating shaft 12 to make the two drive pulleys 8 rotate together. In turn, they drive the two vibrating pulleys 7 to rotate via a belt. The vibrating pulleys 7 cooperate with the transmission shaft to make the vibrating conveyor box 6 vibrate. In specific vibration, a cam needs to be fixed on the surface of the transmission shaft inside the vibrating conveyor box 6. The cam continuously hits the vibrating plate 14, which in turn drives the vibrating screen plate 15 to vibrate, thereby realizing the function of vibrating feeding.When the material unloading assembly provided by this invention is in operation, a rotating frame 16 is first set up and fixed to the surface of the top of the vibrating conveyor box 6. The support rotating rod 17 can rotate on the rotating frame 16. During material unloading, it is necessary to wait until the motor 11 detects an emergency stop, and then the upper motor 20 starts working, driving the upper pulley 21 to start rotating. The upper pulley 21, in conjunction with the transmission pulley 19, drives the support rotating rod 17 to rotate in the opposite direction to the material feeding direction. The support rotating rod 17 drives the unloading roller 18 to back the blocked material. Multiple transmission pulleys 19 are set up, and each transmission pulley 19 is connected by a belt to drive the transmission, so that multiple transmission pulleys 19 rotate together, thereby... The drive rod 17 and the unloading roller 18 rotate together, simultaneously unloading material from multiple positions on the vibrating screen plate 15. Additionally, the last available drive pulley 19 is connected to the auxiliary pulley 22 via a belt, driving the reciprocating screw 23 to rotate, which in turn drives the unloading plate 24 to reciprocate, clearing blockages. Simultaneously, the limiting slide rod 25 limits the unloading plate 24, ensuring normal unloading and reducing the load during feeding, facilitating subsequent feeding and improving the adaptability of the feeding operation. The entire system uses a current detector to monitor the operating current of the motor 11 in real time and transmits the current signal to the PLC processing module. When an abnormal operating current occurs, the current detection module monitors the current of motor 11 during the feeding process to see if it exceeds the reasonable fluctuation range. Simultaneously, to mitigate other influencing factors, the power supply voltage detection module detects power supply voltage fluctuations, and the line resistance detection module detects changes in line resistance. When the voltage and resistance are normal, but the operating current is greater than or equal to 1.1 times the normal current, it indicates a high load, suggesting the belt may be about to stall. At this point, the PLC processing module controls motor 11 to stop working, followed by load maintenance. After maintenance is completed, motor 11 is restarted, thus preventing damage to the belt, motor 11, etc. The equipment is designed to withstand significant damage, ensuring its lifespan. By incorporating an upper-mounted motor 20, when motor 11 stops due to a detection emergency, the upper-mounted motor 20 starts operating, driving the upper pulley 21 to rotate. The upper pulley 21, in conjunction with the transmission pulley 19, drives the support rod 17 to rotate in the opposite direction to the material feeding direction. The support rod 17 then drives the unblocking roller 18 to retract the clogged material. Furthermore, the transmission pulley 19, in conjunction with the auxiliary pulley 22, drives the reciprocating screw 23 to rotate, which in turn drives the unblocking plate 24 to reciprocate, clearing the clogged material. This reduces the load during feeding, facilitating subsequent feeding and improving the adaptability of the feeding process.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
