[0036] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0037] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0038] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0039] Figure 1 This is a schematic diagram of the structure of a lubrication system for a slicer provided in an embodiment of the present disclosure. Figure 1The lubrication system for a slicer includes an axle temperature detection module, a timing module, a main control module, a drive module and an oil pump; the axle temperature detection module is used to detect the bearing temperature, and the axle temperature detection module is connected to the main control module; the timing module is used for timing, and the timing module is connected to the main control module; the first end of the drive module is connected to the main control module, and the second end of the drive module is connected to the oil pump.

[0040] In this embodiment, the shaft temperature detection module is arranged near the bearing of the slicer to detect the temperature change of the bearing in real time. The bearing is a key component in the slicer that bears high loads and is prone to heat generation due to friction. Excessive temperature will lead to decreased lubrication performance and bearing damage. Once it is detected that the temperature exceeds the preset safety range, the shaft temperature detection module will immediately send a signal to the main control module. The main control module is used to receive signals from the shaft temperature detection module and the timing module, and process this information according to the preset logic. For example, after receiving the temperature data, the main control module will make a judgment based on the preset temperature threshold. If the bearing temperature exceeds the set upper limit, the main control module will send an instruction to the drive module. After receiving the instruction, the drive module will start the oil pump, which can draw lubricating oil from the oil pot, and then provide lubricating oil to the bearing through the oil circuit to reduce the bearing temperature.

[0041] During the continuous operation of the slicer, the timing module is used to trigger regular lubrication cycles, such as automatically starting the lubrication process at certain intervals, or forcing lubrication for preventive maintenance after the equipment has been running for a period of time, to ensure the regularity and timeliness of lubrication.

[0042] During the operation of the slicer, when the lubrication cycle has not yet expired, if the shaft temperature detection module detects that the bearing temperature exceeds the set value, the main control module will also trigger the drive module to start the oil pump to reduce the bearing temperature. When the slicer is lubricated because the bearing temperature is too high, the current timing cycle of the timing module will be reset to zero, and the timing will be restarted after the lubrication is completed.

[0043] It can be concluded from the above that this embodiment realizes real-time detection of slicer bearing temperature and intelligent lubrication control by integrating shaft temperature detection module, timing module, main control module, drive module and oil pump. The setting of shaft temperature detection module can accurately capture the change of bearing temperature. Once the temperature is found to be beyond the safe range, the lubrication process is immediately triggered, which effectively avoids the risk of bearing damage due to overheating and significantly improves the stability and safety of the slicer. At the same time, the introduction of timing module realizes the timing control of lubrication cycle, ensures the regularity and timeliness of lubrication, and effectively extends the service life of bearing. The whole system not only reduces maintenance cost, but also improves production efficiency, realizes the perfect combination of preventive maintenance and intelligent lubrication, and provides strong guarantee for the stable and efficient operation of slicer.

[0044] like Figure 2As shown, in one embodiment of the present disclosure, the lubrication system for the slicer also includes an oil level detection module and an alarm module; the oil level detection module is used to detect the oil level of the oil pot, and the oil level detection module is connected to the main control module; the alarm module is connected to the main control module.

[0045] In this embodiment, the lubrication system of the slicer further enhances its intelligence and self-maintenance capabilities, and provides additional safety protection for the stable operation of this embodiment by integrating an oil level detection module and an alarm module.

[0046] In this embodiment, the oil level detection module is used to detect the lubricating oil level in the oil pot in real time. Lubricating oil is the key to ensure that the slicer can work continuously and efficiently. Insufficient oil level may lead to insufficient lubrication, causing equipment overheating and increased wear. The oil level detection module detects the oil level through a sensor. Once the oil level is found to be lower than the preset safety limit, the low oil level signal is immediately transmitted to the main control module.

[0047] When the main control module receives the oil level is lower than the preset limit, the main control module will send an alarm command to the alarm module, and then the alarm module will respond immediately, and can notify the maintenance personnel to replenish the lubricating oil in time through sound and light alarms, display prompts or directly send messages to operators, so as to avoid equipment shutdown or damage caused by low oil level. The integration of the alarm module improves the response speed of the system, ensures the timely resolution of problems, and reduces the potential losses caused by ignoring or failing to detect the insufficient oil level in time.

[0048] In this embodiment, this not only avoids the risk of bearing damage and downtime caused by insufficient lubricating oil, but also improves the response speed of the operator through timely alarm prompts, ensuring that the slicer runs stably under sufficient lubrication. Therefore, the lubrication system for the slicer of this embodiment not only improves the safety and reliability of the equipment, but also reduces maintenance costs and improves production efficiency.

[0049] like Figure 3 As shown, in one embodiment of the present disclosure, the lubrication system for the slicer also includes a feedback module and a selection switch module; the drive module includes a first drive module and a second drive module; the selection end of the selection switch module is connected to the main control module, the first output end of the selection switch module is connected to the first end of the first drive module, the second output end of the selection switch module is connected to the first end of the second drive module, the second end of the first drive module is connected to the second end of the second drive module, and the second end of the first drive module is connected to the oil pump; the first end of the feedback module is connected to the second end of the first drive module, and the second end of the feedback module is connected to the main control module.

[0050] In this embodiment, the lubrication system for the slicer is further optimized and enhanced, and the system becomes more flexible and reliable by introducing a feedback module and a selection switch module, as well as two drive modules (a first drive module and a second drive module).

[0051] In this embodiment, the selection switch module allows the main control module to select which drive module to activate according to actual needs or preset conditions. The selection end of the selection switch module is connected to the main control module, so that it can decide whether to start the first drive module or the second drive module according to the signal from the shaft temperature detection module, the oil level detection module or other sensors, or based on the preset lubrication strategy.

[0052] The design of the first drive module and the second drive module allows the system to have redundancy and backup. Under normal circumstances, one of the drive modules can be selected to drive the oil pump for lubrication. However, if one drive module fails or fails, the other drive module can immediately take over the work to ensure that the lubrication system can continue to operate, thus avoiding the risk of downtime caused by drive module failure.

[0053] The feedback module is used to detect the working status of the drive module and the oil pump in real time, and feed back the relevant information to the main control module. In this way, the main control module can understand the operation of the lubrication system in real time and make adjustments or interventions as needed. If any abnormal situation is detected, such as a drive module failure, the main control module can immediately take measures, such as switching the drive module, issuing an alarm, etc., to ensure the stability and safety of the system.

[0054] In this embodiment, the lubrication system for the slicer is made more flexible, reliable and efficient by introducing a feedback module and a selection switch module, as well as the design of two drive modules. This design not only improves the safety and stability of the system, but also reduces maintenance costs and improves production efficiency.

[0055] like Figure 4 As shown, in one embodiment of the present disclosure, the shaft temperature detection module includes a temperature sensor U7, a resistor R19, a resistor R20, an operational amplifier U9 and a resistor R21; the power supply end of the temperature sensor U7 is connected to the VCC power supply, the ground end of the temperature sensor U7 is grounded, the output end of the temperature sensor U7 is connected to the first end of the resistor R19, the second end of the resistor R19 is connected to the in-phase input end of the operational amplifier U9, the inverting input end of the operational amplifier U9 is grounded through the resistor R20, the output end of the operational amplifier U9 is connected to the inverting input end of the operational amplifier U9 through the resistor R21, and the output end of the operational amplifier U9 is connected to the main control module.

[0056] In this embodiment, the temperature sensor U7 is responsible for directly sensing the temperature change of the bearing. The temperature sensor U7 is used to detect the temperature signal of the bearing and convert it into an electrical signal output. The output end of the temperature sensor U7 is connected to the first end of the resistor R19, and the second end of the resistor R19 is connected to the in-phase input end of the operational amplifier U9, forming an input channel for the temperature signal.

[0057] The electrical signal output by the temperature sensor U7 is relatively weak and cannot be effectively recognized by the main control module. Therefore, the operational amplifier U9 constitutes an amplifier for amplifying the electrical signal output by the temperature sensor U7 and sending the amplified electrical signal to the main control module. The main control module determines the temperature of the bearing based on the size of the received voltage.

[0058] In one embodiment of the present disclosure, the shaft temperature detection module also includes a resistor R18 and an operational amplifier U8; the first end of the resistor R18 is connected to the output end of the temperature sensor U7, the second end of the resistor R18 is connected to the in-phase input end of the operational amplifier U8, the output end of the operational amplifier U8 is connected to the inverting input end of the operational amplifier U8, and the output end of the operational amplifier U8 is connected to the first end of the resistor R19.

[0059] In this embodiment, the electrical signal output by the temperature sensor U7 is relatively weak, and some losses will occur during the signal transmission process, which will cause the voltage applied to the input terminal of the operational amplifier U9 to be not the actual output voltage. In order to improve the accuracy of temperature detection, this embodiment adds an operational amplifier U8 between the output terminal of the temperature sensor U7 and the in-phase input terminal of the operational amplifier U9. The operational amplifier U8 constitutes a follower to improve the effectiveness of signal transmission.

[0060] like Figure 5 As shown, in one embodiment of the present disclosure, the oil level detection module includes a resistor R1, a variable resistor RP1, a capacitor C1, a capacitor C3, an operational amplifier U1, a resistor R2, an oil level sensor U2, a capacitor C4 and a converter U3; the inverting input terminal of the operational amplifier U1 is grounded through the resistor R1, the non-inverting input terminal of the operational amplifier U1 is connected to the first end of the variable resistor RP1, the second end of the variable resistor RP1 is grounded, the non-inverting input terminal of the operational amplifier U1 is grounded through the capacitor C1, the output terminal of the operational amplifier U1 is connected to the inverting input terminal of the operational amplifier U1 through the resistor R2, the output terminal of the operational amplifier U1 is connected to the first end of the oil level sensor U2, and the second end of the oil level sensor U2 is connected to the non-inverting input terminal of the operational amplifier U1 through the capacitor C3; the output terminal of the operational amplifier U1 is connected to the input terminal of the converter U3 through the capacitor C4, and the output terminal of the converter U3 is connected to the main control module.

[0061] In this embodiment, the oil level detection module is used to detect the oil level in the oil pot. An oil level sensor U2 is arranged at the bottom of the oil pot. The oil level sensor U2 in this embodiment can be a pressure-sensitive device. The higher the oil level of the lubricating oil in the oil pot, the greater the pressure on the pressure-sensitive device, and the more serious the deformation of the corresponding resistance strain gauge. The oil level sensor U2 will have different resistance values ​​according to different pressures.

[0062] Resistor R1, variable resistor RP1, capacitor C1, capacitor C3, operational amplifier U1, resistor R2 and oil level sensor U2 constitute an oscillation circuit for outputting a square wave signal. By changing the resistance value of capacitor C3 or the oil level sensor U2, the frequency of the square wave signal output by operational amplifier U1 can be changed. Therefore, when the oil level in the oil pot changes, the frequency of the corresponding square wave output by operational amplifier U1 will also change.

[0063] In this embodiment, the converter U3 can be a frequency-to-voltage converter, which is used to convert the frequency signal into a voltage signal. The voltage output by the converter U3 is different depending on the input frequency. In this way, the main control module can determine the oil level in the oil pot through the voltage output by the converter U3.

[0064] like Figure 5 As shown, in one embodiment of the present disclosure, the oil level detection module also includes a resistor R8, a resistor R9, an operational amplifier U4 and a resistor R10; the first end of the resistor R8 is connected to the output end of the converter U3, the second end of the resistor R8 is connected to the non-inverting input end of the operational amplifier U4, the inverting input end of the operational amplifier U4 is grounded through the resistor R9, the output end of the operational amplifier U4 is connected to the inverting input end of the operational amplifier U4 through the resistor R10, and the output end of the operational amplifier U1 is connected to the main control module.

[0065] In this embodiment, the voltage output by the converter U3 is small, therefore, the resistor R8, the resistor R9, the operational amplifier U4 and the resistor R10 are combined into an amplifier circuit for amplifying the voltage signal output by the converter U3, and finally sending the amplified voltage signal to the main control module.

[0066] The resistor R12 and the capacitor C7 form a filter circuit, which is used to filter out interference in the signal and improve the accuracy of oil level detection.

[0067] like Figure 6As shown, in one embodiment of the present disclosure, the circuit structure of the first driving module and the second driving module is the same, and the first driving module includes an operational amplifier U5, a resistor R16, a resistor R17, a switch tube Q1 and a resistor R14; the non-inverting input terminal of the operational amplifier U5 is connected to the main control module, the inverting input terminal of the operational amplifier U5 is connected to the Vref reference voltage, the inverting input terminal of the operational amplifier U5 is grounded through the resistor R17, the output terminal of the operational amplifier U5 is connected to the inverting input terminal of the operational amplifier U5 through the resistor R16, the output terminal of the operational amplifier U5 is connected to the control terminal of the switch tube Q1, the first terminal of the switch tube Q1 is connected to the first terminal of the oil pump, the second terminal of the oil pump is connected to the VDD power supply, the second terminal of the switch tube Q1 is grounded through the resistor R14, and the second terminal of the switch tube Q1 is connected to the inverting input terminal of the operational amplifier U5.

[0068] In this embodiment, during the operation of the slicer, if the lubrication cycle is reached or the temperature of the bearing exceeds the set value, the main control module sends a control instruction to the first drive module or the second drive module. The circuit structure of the first drive module and the second drive module is the same. This embodiment takes the first drive module as an example to provide a specific embodiment. The working principle of the first drive module is:

[0069] When the slicer needs to be lubricated, the main control module outputs a voltage signal to the in-phase input terminal of the operational amplifier U5. The operational amplifier U5 forms a differential amplifier circuit. The operational amplifier U5 outputs a positive voltage signal, the switch tube Q1 is turned on, and the oil pump U6 is connected to the VDD power supply to start extracting lubricating oil from the oil pot. Resistor R14 is used as a sampling resistor. When the switch tube Q1 is turned on, a voltage is generated on the resistor R14, and the voltage on the resistor R14 is added to the inverting input terminal of the operational amplifier U5. When the voltage on the resistor R14 increases, the voltage on the inverting input terminal of the operational amplifier U5 increases, and the voltage output by the operational amplifier U5 decreases, that is, the voltage at the control terminal of the switch tube Q1 decreases, and the current flowing through the resistor R14 decreases, thereby causing the voltage on the resistor R14 to decrease. When the voltage on the resistor R14 decreases, the voltage at the inverting input terminal of the operational amplifier U5 decreases, and the voltage output by the operational amplifier U5 increases, that is, the voltage at the control terminal of the switch tube Q1 increases, and the current flowing through the resistor R14 increases, thereby causing the voltage on the resistor R14 to increase.

[0070] It can be seen that the oil pump in this embodiment can operate in a constant current working state to ensure the stable operation of the oil pump U6.

[0071] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
