[0002] In multi-stage material conveying production lines in industrial manufacturing, the multi-stage conveyor belt linkage material distribution system is the core equipment for material transfer, storage, and loading. Its operational stability, material distribution uniformity, environmental friendliness, and level of intelligent control directly affect the production efficiency of the entire production line, equipment lifespan, and workshop production environment. Traditional multi-stage material conveying and distribution systems generally suffer from significant drawbacks: the feeding belt can only transport materials to a fixed discharge point, the hopper position is fixed and cannot be adjusted, and the distribution target cannot be flexibly switched, easily causing problems such as uneven material distribution, off-center hoppers, and material blockages; the belts mostly run in one direction, and the discharge port can only unload in a fixed direction, making it impossible to quickly switch the material flow direction when downstream equipment or a hopper is under maintenance, seriously affecting production continuity. At the same time, the system lacks accurate and reliable real-time material level monitoring and automatic control methods, relying heavily on manual operation, resulting in low levels of intelligence, large errors, and low efficiency. Furthermore, the conveyor belt easily accumulates material and dust over long-term operation, lacking efficient cleaning mechanisms, which pollutes the environment and accelerates belt wear. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: an automatic material distribution control device for a multi-stage material conveying system, comprising multiple hoppers 1, a PLC controller 9 fixedly connected to the middle of one side of the hopper 1, a traveling seat 2 fixedly connected to the upper sides of both sides of the hopper 1, an electric traveling frame 3 slidably connected to the upper side of the traveling seat 2, a conveyor belt 4 fixedly connected to the middle of the electric traveling frame 3, a forward and reverse motor 5 fixedly connected to one end of the drive shaft of the conveyor belt 4, a receiving seat 6 fixedly connected to the upper side of the conveyor belt 4, a material level detection component 7 fixedly installed inside the hopper 1, a cleaning component 8 fixedly installed at one end of the upper side of the conveyor belt 4, and side plates 10 fixedly connected to both ends of the upper side of the conveyor belt 4.
[0020] Specifically, the material level detection component 7 includes a mounting base 71, which is installed inside the hopper 1. An ultrasonic material level sensor 72 is fixedly connected to one side of the mounting base 71. Mounting screws 73 are symmetrically inserted into both ends of the mounting base 71. The mounting screws 73 are threadedly connected to the hopper 1. A protective component 74 is provided on the outside of the ultrasonic material level sensor 72.
[0021] By adopting the above technical solution, the device is placed at the external conveyor belt. The material enters the receiving seat 6 from the conveyor belt and then falls onto the conveyor belt 4. The forward and reverse motor 5 rotates forward, driving the material to move and conveying it to the hopper 1. When the ultrasonic level sensor 72 detects that the material in the hopper 1 is high, it transmits an electrical signal to the PLC controller 9, thereby controlling the electric walking frame 3 to move on the walking seat 2, thereby driving the conveyor belt 4 to move and move the discharge port of the conveyor belt 4 to another hopper 1, so as to continue the material distribution work. If it is necessary to convey the material to the downstream equipment, the conveyor belt 4 is controlled to move to the rightmost side. At this time, the forward and reverse motor 5 is controlled to reverse, and the conveyor belt 4 is controlled to reverse, conveying the material in the opposite direction to the downstream equipment.
[0022] Specifically, the protective component 74 includes a limiting seat 741, which is fixedly connected to the front side of the mounting base 71, and a protective cover 742 is inserted into the inside of the limiting seat 741.
[0023] By adopting the above technical solution, the protective cover 742 can easily protect the ultrasonic level sensor 72.
[0024] Specifically, a heat-conducting block 746 is fixedly connected to one side of the protective cover 742, and a heat dissipation fin is fixedly connected to one side of the heat-conducting block 746.
[0025] By adopting the above technical solution, the heat-conducting block 746 can conduct heat out of the interior of the protective cover 742.
[0026] Specifically, the protective cover 742 is tightly inserted with limit rods 743 on both sides, and one end of the limit rod 743 is fixedly connected to a mounting cover 744. The mounting cover 744 is internally threaded with an external threaded pipe seat 745. One side of the external threaded pipe seat 745 is fixedly connected to the limit seat 741, and the surface of the external threaded pipe seat 745 is adjusted with a rubber tight pad.
[0027] By adopting the above technical solution, by rotating the mounting cover 744, the mounting cover 744 and the external threaded pipe seat 745 can be separated. Then, the limiting rod 743 can be taken out from the limiting holes on both sides of the protective cover 742 through the mounting cover 744, thereby releasing the limitation on the protective cover 742. Then, the protective cover 742 is dragged down to separate its insertion hole from the detection end of the ultrasonic level sensor 72. After that, the protective cover 742 can be removed to facilitate the inspection and maintenance of the ultrasonic level sensor 72.
[0028] Specifically, the surface of the mounting cover 744 is symmetrically connected with anti-slip rods, and the surface of the anti-slip rods is fixedly fitted with rubber soft sleeves.
[0029] By adopting the above technical solution, the protective rod and rubber soft sleeve make it easy to rotate the mounting cover 744 and to easily install and remove it without the need for special tools.
[0030] Specifically, a positioning block 747 is fixedly connected to the top of the protective cover 742, a positive magnetic block 748 is fixedly connected to the top of the positioning block 747, a negative magnetic block 749 is magnetically attracted to the top of the positive magnetic block 748, and the negative magnetic block 749 is fixedly connected to the positioning hole of the limiting seat 741.
[0031] By adopting the above technical solution, when installing the protective cover 742, the protective cover 742 is placed in the limiting seat 741, and then the protective cover 742 is pushed upwards so that the positioning block 747 is inserted into the positioning hole of the limiting seat 741. At the same time, the through hole at the bottom inside the protective cover 742 fits onto the detection head of the ultrasonic level sensor 72, realizing the positioning and installation of the protective cover 742. Meanwhile, the positive magnetic block 748 and the negative magnetic block 749 facilitate the initial positioning of the protective cover 742 during installation.
[0032] In this embodiment, the material feeding position can be switched through the bidirectionally movable electric walking frame 3 and the bidirectionally movable conveyor belt 4, and materials can be fed into different hoppers 1. At the same time, the conveyor belt 4 reverses to facilitate the transport of materials to downstream equipment. The ultrasonic level sensor 72 facilitates the detection of the material level inside the hopper 1. When the hopper 1 is full, the signal is transmitted to the PLC controller 9, thereby controlling the electric walking frame 3 to move the feeding port of the conveyor belt 4 to another hopper 1.
[0033] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the cleaning component 8 includes a cleaning frame 81, which is fixedly connected above the conveyor belt 4. An electric telescopic rod 82 is fixedly connected to the middle of the bottom of the cleaning frame 81. A connecting seat 83 is fixedly connected to the bottom of the electric telescopic rod 82. A T-shaped plug 85 is tightly inserted into the middle of the connecting seat 83. A cleaning brush 84 is fixedly connected to the bottom of the T-shaped plug 85. The T-shaped plug 85 and the connecting seat 83 are fixed by fixing screws 86.
[0034] By adopting the above technical solution, when the conveyor belt 4 needs to be cleaned, the electric telescopic rod 82 is activated. The electric telescopic rod 82 drives the cleaning brush 84 to move down and make it fit with the conveyor belt 4. Then, the conveyor belt 4 moves and works with the cleaning brush 84 to clean. The fixing screw 86 is unscrewed, and the cleaning brush 84 can be removed for cleaning and replacement by separating it from the connecting seat 83 through the T-shaped plug 85.
[0035] Specifically, stabilizing telescopic rods 87 are fixedly connected to both ends above the connecting seat 83, and the top of the stabilizing telescopic rods 87 is fixedly connected to the cleaning rack 81.
[0036] By adopting the above technical solution, the stable telescopic rod 87 facilitates the stable lifting and lowering of the cleaning brush 84.
[0037] Specifically, an industrial vacuum cleaner 88 is fixedly connected to the top of the cleaning rack 81. The suction pipe of the industrial vacuum cleaner 88 is fixedly connected to a vacuum hood 89 through a branch pipe. One side of the vacuum hood 89 is fixedly connected to the cleaning rack 81.
[0038] By adopting the above technical solution, when cleaning, the industrial vacuum cleaner 88 is started, and the dust is easily sucked away and collected through the dust hood 89.
[0039] In this embodiment, when the device is not in use, the conveyor belt 4 can be cleaned.
[0040] The working principle and usage process of this invention: This multi-stage material conveying system's automatic material distribution control device uses a PLC controller 9 as its control core. Through the coordinated operation of the electric walking frame 3, conveyor belt 4, forward and reverse motor 5, material level detection component 7, and cleaning component 8, it completes the entire process of multi-stage material conveying, automatic bin changing, bidirectional feeding, material level monitoring, and automatic cleaning. The overall working principle is as follows: The external material conveying system feeds the material into the receiving seat 6, and the material falls onto the surface of the conveyor belt 4. The PLC controller 9 starts the forward and reverse motor 5, driving the conveyor belt 4 to rotate forward, smoothly conveying the material to the corresponding hopper 1 to complete the unloading. The side plate 10 can prevent the material from spilling laterally during the conveying process, improving the feeding stability. The material level detection component 7 inside the hopper 1 monitors the material height in the hopper in real time. The ultrasonic material level sensor 72 transmits the material level data to the PLC controller 9 in real time. When the material in the current hopper 1 is detected to have reached the set high level, the PLC controller 9 immediately drives the electric walking frame 3 to move laterally on the walking seat 2, driving the overall displacement of the conveyor belt 4, and accurately switching the unloading port to the next hopper 1 to be filled, realizing uninterrupted automatic hopper changing and material filling, avoiding hopper deviation and material blockage.
[0041] When materials need to be directly transported to downstream equipment instead of silo 1, PLC controller 9 controls the electric walking frame 3 to move to the designated workstation, and at the same time drives the forward and reverse motor 5 to run in the opposite direction, so that the conveyor belt 4 feeds materials in the reverse direction, quickly completing the material flow direction switch and ensuring the continuous operation of the production line when the downstream equipment or silo 1 is under maintenance.
[0042] The ultrasonic level sensor 72 is fully protected by the protective component 74. The protective cover 742 is securely installed through the limit seat 741, the limit rod 743, the mounting cover 744, and the external threaded pipe seat 745. The positioning block 747, the positive magnetic block 748, and the negative magnetic block 749 complete the rapid magnetic positioning. The heat conduction block 746 and the heat dissipation fins promptly dissipate the heat inside the protective cover 742 to prevent the sensor from overheating. At the same time, the overall structure facilitates quick disassembly and maintenance.
[0043] When the equipment is stopped or undergoes regular maintenance, the cleaning component 8 starts operating: the electric telescopic rod 82 pushes the connecting seat 83 and the cleaning brush 84 downwards, so that the cleaning brush 84 fits tightly against the surface of the conveyor belt 4; in conjunction with the low-speed operation of the conveyor belt 4, it completes the cleaning of residual materials and dust, and the stabilizing telescopic rod 87 ensures that the cleaning mechanism rises and falls smoothly without deviation; the industrial vacuum cleaner 88 is started simultaneously, and the dust generated during cleaning is collected through the dust hood 89 to prevent dust from spreading and polluting the environment; the cleaning brush 84 can be quickly installed and removed through the T-shaped insert 85 and the fixing screw 86, which is convenient for replacement and maintenance.
[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
