[0002] With the rapid development of the tobacco industry, achieving high-speed tobacco processing equipment has become a continuous goal pursued by the industry. As a key hub connecting the rolling and packaging processes, the operational stability of the high-altitude tobacco conveyor directly affects product quality and production efficiency. In the rolling and packaging workshop, this equipment, with a total length exceeding 20 kilometers, bears the heavy responsibility of transporting finished tobacco sticks produced by each rolling and packaging unit to the packaging unit.

[0003] However, in the lubrication systems currently used in aerial conveyor systems, the control valves are in direct contact with the lubricating oil. Over long-term operation, the corrosion of the control valves by the lubricating oil can easily lead to component damage and frequent lubrication system failures. Once the lubrication system fails, the stability of the aerial conveyor system will decrease significantly, causing the cigarette packs to become stuck when entering the packer. This will trigger a series of product quality problems, such as scratches on the cigarette pack seals, end damage, or wrinkles, thus affecting production continuity and causing reduced production efficiency and economic losses.

[0026] This embodiment provides a conveyor chain lubrication device, such as... Figure 1As shown, the conveyor belt lubrication device includes an air source 1, a first pipe 2, a control valve 3, an oil tank 4, a second pipe 5, and an oil nozzle 6. The first pipe 2 connects the air source 1 and the oil tank 4. The control valve 3 is installed on the first pipe 2 to control the opening and closing of the air passage in the first pipe 2. The second pipe 5 connects the oil tank 4 and the oil nozzle 6, and the spray nozzle 6 is oriented towards the conveyor belt 100. Through the coordinated arrangement of the air source 1, the first pipe 2, the control valve 3, the oil tank 4, the second pipe 5, and the oil nozzle 6, effective lubrication of the conveyor belt 100 is achieved. Gas source 1 delivers gas to oil storage tank 4 via first pipeline 2. Control valve 3 controls the opening and closing of the gas path, flexibly adjusting the pressure inside oil storage tank 4. This allows lubricating oil to be stably delivered to nozzle 6 via second pipeline 5 and precisely sprayed onto conveyor belt 100, avoiding direct contact between lubricating oil and control valve 3. This effectively prevents the control valve 3 from being corroded and damaged, greatly improving the reliability and service life of the conveyor belt lubrication device. At the same time, it ensures continuous and stable lubrication of conveyor belt 100, reducing the risk of jamming of cigarette sticks due to poor lubrication during transportation, thereby reducing product quality problems, ensuring production continuity, and significantly improving the operational stability of conveyor belt 100.

[0027] In this embodiment, the air source 1 can be an air compressor, which can stably output compressed air and provide a continuous and stable pressure source to ensure that the lubricating oil in the oil tank 4 is smoothly delivered to the oil injector 6; the control valve 3 is an electromagnetic reversing valve, which realizes the rapid opening and closing of the air path through electromagnetic control. It has a fast response speed and precise control, and is convenient to flexibly adjust the air path according to actual production needs, thereby regulating the delivery rhythm and flow of lubricating oil. At the same time, it has high reliability and long service life, effectively avoiding failures caused by frequent operation.

[0028] In this embodiment, the air compressor, acting as the air source 1, continuously outputs compressed gas, which is then transported along the first pipeline 2 to the solenoid directional valve. When the solenoid directional valve is energized and opened, the air path is opened, and the compressed gas smoothly enters the oil storage tank 4 through the first pipeline 2. As gas is continuously injected, the air pressure inside the oil storage tank 4 gradually increases, forming a stable pressure difference. Driven by this pressure, the lubricating oil in the oil storage tank 4 is directionally transported along the second pipeline 5, and finally sprayed evenly and precisely onto the surface of the conveyor belt 100 through the oil nozzle 6, completing the efficient lubrication operation.

[0029] like Figure 1As shown, the conveyor belt lubrication device also includes a detection element 7, a controller 8, and a power supply 9. The detection element 7 is located beside the running path of the conveyor belt 100 and is used to detect the links of the conveyor belt 100. The controller 8 is electrically connected to the detection element 7 and the control valve 3, respectively, and the power supply 9 is electrically connected to the controller 8. The conveyor belt 100 includes multiple links, which are hinged together by components such as pins and sleeves to form a flexible transmission belt that can bend and transmit power. The detection element 7 is installed beside the running path of the conveyor belt 100 and can accurately capture signal changes as the links pass. Whenever a link passes, the detection element 7 immediately transmits a trigger signal to the controller 8. The controller 8 has a counting function to accurately count the signals transmitted by the detection element 7. Based on a preset lubrication threshold (such as triggering lubrication once every certain number of links), when the count reaches the set value, the controller 8 quickly sends an electrical signal to the control valve 3, driving the air source 1 to evenly spray the lubricating oil in the oil tank 4 onto the chain belt through the oil nozzle 6. This design avoids the problems of untimely or excessive lubrication caused by chain speed fluctuations in traditional timed lubrication modes. It ensures that the lubrication operation is highly consistent with the actual operating needs of the chain, effectively reducing lubricant consumption and significantly reducing the risk of wear on chain links due to insufficient lubrication. This extends the service life of the conveyor chain by 100%. At the same time, by continuously monitoring the chain link count, it can also promptly detect potential faults such as chain jamming and abnormal operation, further improving the stability and reliability of equipment operation and providing a strong guarantee for efficient and continuous production.

[0030] In this embodiment, the detection element 7 is a photoelectric switch, the controller 8 is a PLC (Programmable Logic Controller), and the power supply 9 is a 24V power supply. The photoelectric switch emits an infrared beam; when a chain link passes through the blocked light path, an instantaneous electrical signal change is generated. Leveraging its non-contact detection, fast response, and strong anti-interference capabilities, the photoelectric switch can stably capture information about the passing chain links. The PLC controller has a high-speed counting function, accurately recording the chain link signals transmitted by the photoelectric switch and performing logical operations through its built-in program. For example, when the count reaches a preset threshold (e.g., triggering lubrication once every 100 chain links), the PLC controller immediately outputs a control signal to drive the control valve 3 to open, achieving precise lubrication. Simultaneously, the PLC controller also supports data storage and communication functions, recording chain link count data, lubrication frequency, and other information in real time, facilitating production data traceability and equipment status analysis. The 24V power supply provides stable power to the detection element 7 and the controller 8, ensuring continuous and stable operation of the system under complex working conditions. The close cooperation of these three components enables automated and precise control of the conveyor belt lubrication device, effectively improving equipment operating efficiency and reliability.

[0031] like Figure 1As shown, the conveyor chain lubrication device also includes a manual switch 10, which is electrically connected to the controller 8. In daily production, the conveyor chain lubrication device is automatically operated by the controller 8 based on the chain link count data from the detection element 7, ensuring the accuracy and stability of lubrication. However, when the equipment is under commissioning, maintenance, or encounters a sudden abnormality, the operator can directly send a command to the controller 8 via the manual switch 10 to immediately start or stop lubrication. For example, during equipment installation and commissioning, manually triggering lubrication can quickly test the spraying effect of the oil injector 6; when the equipment malfunctions and stops, manually shutting off lubrication can prevent oil waste; when the automatic counting system experiences a brief abnormality (such as a false triggering of the detection element 7), manual intervention can ensure that the lubrication process is not disturbed, maintaining production continuity. This complementary automatic and manual control mechanism retains the high efficiency of intelligent counting lubrication while giving operators the initiative to flexibly adjust the system, effectively reducing the risk of production interruption due to system failures or special operating conditions, and improving the convenience and overall applicability of equipment operation and maintenance.

[0032] like Figure 1 As shown, the conveyor belt lubrication device also includes a zeroing switch 11, which is electrically connected to the controller 8 and used to clear the accumulated link count value of the controller 8. In actual production, the zeroing switch 11 can quickly reset the accumulated link count value according to different production needs: when switching production batches or replacing the conveyor belt 100, the operator can press the zeroing switch 11 to reset the current count data to zero, so that the controller 8 matches the lubrication needs of the new working conditions with a new counting cycle, avoiding the lubrication cycle disorder caused by using old data; after the conveyor belt 100 is debugged or repaired, the zeroing operation can ensure that the system is put into operation in an accurate initial state, preventing abnormal counting during debugging from interfering with normal production logic. In addition, if the counting data deviates due to the false triggering of the detection element 7, the zeroing switch 11 can correct the erroneous accumulated value in time, so that the count returns to the true and accurate state, ensuring the reliability of the lubrication command triggering. This design effectively enhances the adaptability and fault tolerance of the conveyor belt lubrication device, meeting the needs of diverse production scenarios and quickly responding to sudden data anomalies. It maintains a precise match between lubrication operation and the belt's running state, further improving the stability of the conveyor belt 100 operation.

[0033] like Figure 1As shown, the conveyor belt lubrication device also includes an air circuit breaker 12, which is connected in series between the power supply 9 and the controller 8. The air circuit breaker 12 has overload, short circuit, and undervoltage protection functions. When the current in the power supply 9 line exceeds the rated value due to excessive load or electrical component failure, the thermal trip unit or electromagnetic trip unit inside the air circuit breaker 12 will quickly activate and automatically disconnect the power supply 9, preventing the controller 8 from burning out due to overheating or a sudden surge of large current. If a short circuit fault occurs due to insulation damage, the air circuit breaker 12 can trip in a very short time, preventing the fault from spreading and reducing safety risks such as fire. Simultaneously, when the voltage of the power supply 9 abnormally drops to a critical value (undervoltage state), the air circuit breaker 12 can promptly disconnect the circuit, preventing the controller 8 from experiencing logic errors or data loss due to voltage instability. Furthermore, the air circuit breaker 12 can also serve as the system's manual main switch. During equipment maintenance and repair, operators can safely isolate the power supply 9 by disconnecting the air circuit breaker 12, effectively preventing electric shock accidents.

[0034] In this embodiment, the conveyor chain lubrication device also includes an alarm (not shown), which is electrically connected to the controller 8. When the controller 8 determines an abnormal situation through the chain link count data of the detection element 7, such as abnormal fluctuations in the chain link count per unit time (indicating chain jamming or breakage), failure to complete the preset chain link count within the lubrication cycle (possibly due to sensor failure or chain stagnation), or when the air circuit breaker 12 is triggered by overload or short circuit, it will immediately send a signal to the alarm to trigger an audible and visual alarm.

[0035] Optionally, an audible and visual alarm is selected. When the controller 8 detects a fault such as abnormal chain belt counting, lubrication system failure, or air circuit breaker 12 tripping, it immediately sends a command to the alarm, simultaneously activating flashing lights and a buzzer alarm. After the operator handles the abnormality, the alarm is turned off through a reset operation, and the system returns to normal. This design not only significantly improves fault response efficiency but also assists operators in quickly locating the root cause of the problem through differentiated combinations of audible and visual signals, reducing downtime for troubleshooting and further ensuring production continuity and equipment safety.

[0036] In this embodiment, the conveyor belt lubrication device also includes a throttle valve (not shown). The throttle valve is installed on the first pipe 2, located between the control valve 3 and the oil storage tank 4, and is used to regulate the gas flow rate in the first pipe 2. By precisely controlling the gas flow rate in the first pipe 2 through the throttle valve, the lubricating oil delivery process can be precisely controlled, significantly improving the lubrication effect and system stability. When the gas source 1 supplies gas to the oil storage tank 4 through the control valve 3, the throttle valve adjusts the gas flow rate and pressure by changing the valve opening: if the valve opening is reduced, the gas flow rate entering the oil storage tank 4 decreases, the gas pressure rise rate in the tank slows down, and the flow rate of the lubricating oil delivered to the nozzle 6 through the second pipe 5 decreases accordingly. The injection frequency and injection volume are reduced accordingly, which is suitable for low-speed operation or light-load conditions of the conveyor belt, avoiding lubricating oil waste; conversely, increasing the valve opening can increase the gas flow rate, accelerate the rise of gas pressure in the tank, and allow the lubricating oil to be injected at a faster speed, meeting the higher lubrication intensity requirements when the conveyor belt is running at high speed or under heavy load.

[0037] like Figure 1 As shown, the conveyor chain lubrication device also includes a filter 13, which is installed on the first pipe 2 between the control valve 3 and the air source 1 to filter the gas in the first pipe 2. The filter 13 can effectively purify the gas delivered by the air source 1. The gas output from the air compressor often contains impurities such as rust particles, oil, and dust. If it enters the system directly without treatment, on the one hand, the impurities will enter the oil storage tank 4 with the gas, contaminating the lubricating oil, causing the nozzle 6 to become clogged, reducing the lubrication effect, and even aggravating the wear of the chain. On the other hand, these impurities will enter the control valve 3, which will wear down the valve core, sealing ring, and other precision components, shorten the service life of the control valve 3, and increase the cost of component replacement and equipment downtime for maintenance. The intervention of the filter 13 can efficiently filter out solid particles and liquid oil in the gas through the physical interception and adsorption of the filter element, ensuring that the gas entering the oil storage tank 4 is clean and dry. This not only avoids lubricant contamination and maintains the precise injection performance of the injector 6, ensuring uniform and stable lubrication of the chain belt and reducing quality problems caused by poor lubrication; it also significantly reduces the wear risk of core components such as the control valve 3, improves the overall reliability of the system, extends the service life of the equipment, and reduces production interruptions and economic losses caused by component failures.

[0038] like Figure 1 As shown, the conveyor belt lubrication device also includes a pressure reducing valve 14. The pressure reducing valve 14 is installed on the first pipeline 2, located between the control valve 3 and the filter 13, and is used to regulate the gas pressure in the first pipeline 2. The pressure reducing valve 14 pre-processes the gas output from the gas source 1, stabilizing the initially high and fluctuating gas pressure to the safe operating range of the system. This prevents high-pressure gas from directly impacting the internal precision structure of the control valve 3 (such as the valve core and sealing ring of the solenoid directional valve), reducing the risk of valve core wear, and providing a stable pressure basis for the flow regulation of the subsequent throttle valve.

[0039] like Figure 1 As shown, the conveyor belt lubrication device also includes a pressure gauge 15, which is installed on the first pipeline 2 between the control valve 3 and the pressure reducing valve 14. The pressure gauge 15 is used to detect the gas pressure in the first pipeline 2. Although the pressure reducing valve 14 can regulate the pressure of the gas source 1 to the target value, in actual operation, its output pressure may deviate from the set value due to factors such as fluctuations in the gas source 1 and performance degradation of the pressure reducing valve 14. The real-time monitoring function of the pressure gauge 15 can accurately capture the gas pressure data between the outlet of the pressure reducing valve 14 and the inlet of the control valve 3. Operators can intuitively obtain the current pressure value through the dial pointer or digital display and promptly detect abnormal gas pressure.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
