[0040] 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.

[0041] 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.

[0042] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0043] Figure 1 This is a schematic diagram of the structure of a weighing system of a slicer provided in an embodiment of the present disclosure. Figure 1 The weighing system of the slicer includes a first weight monitoring module 101 , a control module 102 , a driving module 103 and a frequency monitoring module 104 .

[0044] The control module 102 is connected to the first weight monitoring module 101 , the driving module 103 and the frequency monitoring module 104 respectively.

[0045] The first weight monitoring module 101 is configured to monitor the weight of the sliced ​​meat. The frequency monitoring module 104 is configured to monitor the number of slices performed by the slicer per unit time.

[0046] The driving module 103 is configured to control the number of slices per unit time of the slicer based on the instruction information of the control module 102 .

[0047] In the present embodiment, the first weight monitoring module 101 includes an electronic scale. The first weight monitoring module 101 may include real-time monitoring of the weight of the sliced ​​meat. During the slicing process, whenever a new slice of meat is cut and falls into the electronic scale, the pressure monitoring data of the electronic scale changes. At this time, the first weight monitoring module 101 may record the current weight information. This data may be transmitted to the control module 102 for further processing. The frequency monitoring module 104 may include monitoring the number of slices per unit time of the slicer, calculating and recording the slicing frequency of the slicer, and transmitting the frequency to the control module 102, and the control module 102 may adjust the instruction information of the drive module 103 accordingly to adjust the slicing speed according to actual conditions and needs.

[0048] In this embodiment, the control module 102 can receive data from the first weight monitoring module 101 and the frequency monitoring module 104, and analyze and process the data. Based on the analysis results, the control module 102 can generate corresponding instruction information and send it to the drive module 103. The drive module 103 can include receiving the instruction information of the control module 102 and controlling the slicing speed of the slicer accordingly. When the slicing speed exceeds a preset threshold, or the weight of the sliced ​​meat does not meet the requirements, the control module 102 can generate corresponding instruction information to control the drive module 103 to adjust the slicing speed and the number of slicing times of the slicer.

[0049] Exemplarily, the first weight monitoring module 101 can monitor the weight of the sliced ​​meat in real time through a high-precision sensor. Whenever the slicer completes a slicing operation, the module will immediately record and send the weight data of the meat slice to the control module 102. Receive data from the first weight monitoring module 101 and the frequency monitoring module 104, and perform rapid analysis. The frequency monitoring module 104 can record the number of slices of the slicer per unit time, and this data is also sent to the control module 102. The control module 102 can calculate whether the current slicing operation meets the standard based on the preset slicing weight standard and the actual slicing speed. When there is a deviation between the actual slicing weight and the standard value, the control module 102 can generate instruction information and transmit the instruction information to the driving module 103. The driving module 103 adjusts the slicing speed of the slicer based on the instruction information of the control module 102, thereby controlling the number of slices per unit time to ensure that the weight of each piece of meat meets the standard. The adjusted slicer will continue the slicing operation and collect data again through the first weight monitoring module 101 and the frequency monitoring module 104. These new data will go through the above data processing process again to form a closed-loop control system to continuously optimize and adjust the slicer's slicing operation.

[0050] For example, in the application scenario of cutting steak, the weighing system of the slicer can play an important role. Before slicing, the staff can set the desired steak slice weight and slicing speed through the control module 102. When the slicer starts working, the first weight monitoring module 101 can monitor the weight of the cut steak slices in real time and transmit the weight information data to the control module 102. When the weight of the currently cut steak slices does not meet the preset threshold, the slicing speed of the slicer can be adjusted through the drive module 103 to ensure that the weight of the subsequent steak slices meets the requirements. The frequency monitoring module 104 is also working continuously, monitoring the number and speed of slicing of the slicer, and transmitting the slicing frequency information to the control module 102. When the slicing speed is lower than the preset threshold, the control module 102 can send instructions to the drive module 103 to increase the slicing speed. When the slicing speed exceeds the preset threshold, the control module 102 will control the drive module 103 to reduce the slicing speed, improve product quality, and ensure the stability and safety of the slicer.

[0051] This embodiment monitors the weight of the sliced ​​meat in real time through the first weight monitoring module 101, ensuring that the weight information of the meat slices can be accurately grasped during the production process, effectively avoiding quality problems caused by uneven weight, and improving the overall quality of the product. The frequency monitoring module 104 monitors the number of slices per unit time of the slicer, providing key real-time data support for the control module 102. This enables the control module 102 to adjust the generated instruction information based on the actual slicing frequency and transmit it to the drive module 103, thereby achieving accurate control of the slicing speed. Through the instruction control of the control module 102 to the drive module 103, this embodiment can flexibly adjust the number of slices of the slicer to meet different production needs. This dynamic adjustment not only improves production efficiency, but also optimizes energy utilization and reduces production costs.

[0052] like Figure 2 As shown, in one embodiment of the present disclosure, a weighing system for a slicer further includes: a second weight monitoring module 105 .

[0053] The second weight monitoring module 105 is connected to the control module 102, and the second weight monitoring module 105 is configured to monitor the weight of the meat slices to be cut on the slicer.

[0054] In this embodiment, the first weight monitoring module 101 can monitor the weight of the sliced ​​meat in real time to ensure that the weight of each steak meets the preset standard. The second weight monitoring module 105 can monitor the weight of the meat to be cut on the slicer and provide the control module 102 with data on the weight of the raw material. Both modules are connected to the control module 102 to transmit data in real time. The control module 102 calculates the appropriate slicing strategy and speed based on the preset slice weight and quantity and the weight of the meat to be cut. At the same time, the control module 102 can determine whether the weight monitoring fails based on the weight of the sliced ​​meat and the remaining meat after each cutting operation.

[0055] For example, in the production line of cutting steak, the weighing system of the slicer plays a vital role. For example, the preset weight of each steak is 200 grams. The second weight monitoring module 105 first monitors the weight of the steak to be cut, such as 1000 grams. The second weight monitoring module 105 transmits the initial raw material weight of the steak to be cut to the control module 102. The control module 102 calculates that it needs to be cut into 5 slices according to the initial raw material weight and the preset weight of each steak, and the slicing speed is 0.5 seconds / time. The driving module 103 controls the slicing speed of the slicer according to the instructions of the control module 102 to ensure that the weight of each steak is about 200 grams. During the slicing process, the first weight monitoring module 101 monitors in real time whether the weight of the cut steak slices exceeds the preset threshold, for example, the weight of each steak is set between 190 grams and 210 grams. When the weight of the cut meat slices exceeds 210 grams, the control module 102 will adjust the slicing strategy in time, such as appropriately increasing the slicing speed. When the weight of the sliced ​​meat is less than 190 grams, the control module 102 will adjust the slicing strategy in time, such as appropriately reducing the slicing speed.

[0056] Exemplarily, each time the slicer cuts once, the first weight monitoring module 101 and the second weight monitoring module 105 respectively transmit the weight information monitored by each to the control module 102. When the weight of the sliced ​​meat and the sliced ​​meat to be sliced ​​is inconsistent with the weight of the initial meat, the control module 102 can determine that a failure has occurred in the weight monitoring process and remind the staff to make timely adjustments and maintenance.

[0057] This embodiment can monitor the weight of the meat slices to be cut on the slicer in real time and accurately, ensuring that each cutting can be performed based on accurate weight data, thereby greatly improving the processing accuracy and product quality of the meat slices. Through the connection with the control module 102, the first weight monitoring module 101 and the second weight monitoring module 105 can timely feedback data to the control system, so that the slicer can automatically adjust the cutting parameters such as cutting thickness, speed, etc. according to the real-time weight data, realize intelligent operation, and improve production efficiency and automation level. In addition, this embodiment also helps to achieve accurate utilization of raw materials, reduce waste, and reduce costs.

[0058] In one embodiment of the present disclosure, the frequency monitoring module 104 includes: a Hall sensor.

[0059] The Hall sensor is arranged at the front end of the meat slice cutting surface, and the Hall sensor is configured to monitor the change of the magnetic field before and after the blade cuts the meat slice.

[0060] In this embodiment, based on the Hall effect, when current passes through a conductor placed in a magnetic field, a potential difference is generated in a direction perpendicular to the current and the magnetic field. In the process of cutting meat slices, the blade will cut the metal part (such as the blade itself or related mechanical parts) in the magnetic field when rotating or moving, thereby causing changes in the magnetic field. The Hall sensor is placed near the blade and can sensitively capture this magnetic field change. When the blade cuts the meat slice, the contact and separation between the blade and the meat slice will cause a slight change in the magnetic field strength. The Hall sensor can detect the change in the magnetic field strength and convert it into an electrical signal, thereby realizing real-time monitoring of the blade cutting frequency.

[0061] For example, in the meat processing industry, the frequency monitoring module 104 and the application of the Hall sensor can greatly improve the working efficiency and safety of the slicer. By real-time monitoring of the cutting frequency of the blade, the control system can accurately determine the working state of the blade, thereby timely adjusting the cutting speed or performing necessary maintenance.

[0062] For example, when the blade is worn due to long-term use and the cutting frequency is less than the preset standard frequency, the control module 102 can remind the operator to replace the blade through instructions to avoid affecting product quality and production efficiency due to excessive wear of the blade.

[0063] By monitoring the change of cutting frequency, this embodiment can timely discover possible failures or abnormal conditions of the slicer, so as to carry out timely processing and ensure the stable operation of the production line.

[0064] like Figure 3 As shown, in one embodiment of the present disclosure, the frequency monitoring module 104 includes: a power supply VCC, a voltage stabilizing diode D1, a resistor R10, a resistor R11, a resistor R12, a resistor R13, a variable resistor RP5, a Hall sensor H1, an amplifier U1 and a capacitor C4.

[0065] The resistor R10 has a first end connected to the power source VCC, and a second end connected to the first end of the voltage stabilizing diode D1 and the first end of the resistor R11 respectively.

[0066] The second end of the voltage zener diode D1 is connected to the second end of the resistor R11 , and the second end of the resistor R11 is grounded.

[0067] The Hall sensor H1 has a first end connected to the first end of the resistor R13 , and a second end connected to the second end of the resistor R11 and the fixed end of the resistor RP5 .

[0068] The second end of the resistor R13 is connected to the non-inverting input terminal of the amplifier U1.

[0069] The amplifier U1 has an inverting input terminal connected to the sliding terminal of the variable resistor RP5, the first terminal of the resistor R12 and the first terminal of the capacitor C4, and an output terminal connected to the second terminal of the resistor R12 and the second terminal of the capacitor C4.

[0070] In this embodiment, the working principle of the frequency monitoring module 104 mainly depends on the power supply of the power supply VCC, the voltage stabilizing effect of the voltage stabilizing diode D1, the resistor network (R10, R11, R12, R13), the adjustment function of the resistor RP5, the magnetic field detection capability of the Hall sensor H1 and the signal amplification effect of the amplifier U1.

[0071] Exemplarily, the power supply VCC provides a stable voltage for the entire circuit through the resistor R10. The resistor R10 and the voltage regulator diode D1 together form a simple voltage regulator circuit to ensure that a stable voltage is provided to the subsequent circuit. The voltage regulator diode D1 stabilizes the voltage at a specific value, and its second end (i.e., cathode) is connected to the second end of the resistor R11 and grounded to form a voltage reference point. The Hall sensor H1 is placed near the blade to detect the change in the magnetic field generated when the blade cuts the meat slice. When the blade cuts the meat slice, the magnetic field strength changes, and the Hall sensor H1 outputs a corresponding voltage signal according to the change in the magnetic field strength. This voltage signal is transmitted to the non-inverting input terminal of the amplifier U1 through the resistor R13. The amplifier U1 is a differential amplifier used to amplify the difference between the input signal and the reference signal.

[0072] In this circuit, the sliding end of the variable resistor RP5 is connected to the inverting input end of the amplifier U1. Since the slicer will generate a magnetic field signal when it is not cutting, the resistance of the variable resistor RP5 can be adjusted so that the output of the amplifier U1 is 0 when the slicer is not cutting. The resistor R12 and the capacitor C4 form a feedback network to stabilize the output of the amplifier U1 and set the amplification factor. When the voltage signal detected by the Hall sensor H1 changes, the difference between this signal and the reference voltage at the inverting input end will be amplified by the amplifier U1 and output from the output end. The output signal can be further connected to other circuits or devices to monitor the cutting frequency of the blade.

[0073] This embodiment has the beneficial effects of stable power supply, accurate magnetic field detection, flexible signal adjustment, signal amplification and stabilization, etc. These effects together improve the performance and reliability of the slicer, bringing significant benefits to the meat processing industry.

[0074] like Figure 3 As shown, in one embodiment of the present disclosure, the frequency monitoring module 104 further includes: a comparator U2, a NOT gate U3 and a NOT gate U4.

[0075] The comparator U2 has a non-inverting input terminal for receiving a reference voltage, an inverting input terminal connected to the output terminal of the amplifier U1, and an output terminal connected to the input terminal of the NOT gate U3.

[0076] The output end of the NOT gate U3 is connected to the input end of the NOT gate U4 , and the output end of the NOT gate U4 is connected to the control module 102 .

[0077] In this embodiment, the comparator U2 has a non-inverting input terminal and an inverting input terminal. The non-inverting input terminal is used to receive a reference voltage (preset voltage value), which will be used as a reference for comparison. The inverting input terminal is connected to the output terminal of the amplifier U1 to receive the voltage signal processed by the amplifier U1. The comparator U2 can continuously compare the voltage values ​​of its non-inverting input terminal and the inverting input terminal. When the voltage of the inverting input terminal is higher than the reference voltage of the non-inverting input terminal, the output terminal of the comparator will generate a low-level signal. Conversely, when the voltage of the inverting input terminal is lower than the reference voltage of the non-inverting input terminal, the output terminal will generate a high-level signal. The output terminal of the comparator U2 is connected to the input terminal of the NOT gate U3, and the comparison result is passed to the NOT gate U3. The NOT gate U3 receives the output signal from the comparator U2. The NOT gate can invert the input signal and output it, that is, when the input is high, the output is low. When the input is low, the output is high. The output end of the NOT gate U3 is connected to the input end of the NOT gate U4, and the inverted signal is passed to the NOT gate U4. The NOT gate U4 receives the output signal from the NOT gate U3 and performs the inversion operation again. The output signal of the NOT gate U4 is actually the same as the original comparison result of the comparator U2. For example, when the comparator U2 outputs a high level, the NOT gate U4 also outputs a high level. When the comparator U2 outputs a low level, the NOT gate U4 also outputs a low level. The circuit composed of the two NOT gates plays a shaping role, ensuring that the pulse signal is more stable. The output end of the NOT gate U4 is connected to the control module 102, and the final frequency monitoring result is passed to the control module 102. The control module 102 can perform corresponding operations or decisions based on this result.

[0078] The present embodiment plays a shaping role, i.e., shaping and stabilizing of the pulse signal, through the configuration of two NOT gates U3 and U4. The NOT gate circuit can invert and then invert the signal output by the comparator U2, thereby eliminating possible noise or signal distortion, and ensuring that the pulse signal transmitted to the control module 102 is more stable and reliable. Although two NOT gates are used to shape the signal, this design has a simple structure and low cost, and does not actually increase too much complexity and cost. The design of the frequency monitoring module 104 is flexible, and the value of the reference voltage can be adjusted according to actual needs to adapt to the monitoring needs of different frequency ranges.

[0079] like Figure 4 As shown, in one embodiment of the present disclosure, the driving module 103 includes: a resistor R20, a power supply VDD, a diode D2, a transistor Q4, a resistor R21, a resistor R22, a resistor R23, a resistor R24, a transistor Q5, a diode D3, a transistor Q6 and a motor U5.

[0080] The resistor R20 has a first end connected to the power source VDD, and a second end connected to the input end of the control module 102 and the diode D2 respectively.

[0081] The output end of the diode D2 is connected to the base of the transistor Q4.

[0082] The transistor Q4 has a collector connected to the first end of the resistor R20 , and an emitter connected to the first end of the resistor R21 and the first end of the resistor R22 .

[0083] The second end of the resistor R21 is connected to the base of the transistor Q5 , and the second end of the resistor R22 is grounded.

[0084] The transistor Q5 has a collector connected to the first end of the motor U5 and the input end of the diode D3, and an emitter connected to the first end of the resistor R23 and the first end of the resistor R24.

[0085] The transistor Q6 has a base connected to the second end of the resistor R24, a collector connected to the second end of the motor U5, and an emitter connected to the output end of the diode D3.

[0086] The output end of the diode D3 is used to connect to the power supply VDD.

[0087] In the present embodiment, the power supply VDD provides electric energy for the entire driving module 103 through the resistor R20. The resistor R20 not only plays a current limiting role, but also serves as the collector load of the transistor Q4. The second end of the resistor R20 is connected to the control module 102 to receive the control signal from the control module 102. This control signal drives the base of the transistor Q4 through the resistor R20 and the diode D2. The transistor Q4 plays a switch role. When the control signal is a high level, the diode D2 is turned on, providing current for the base of the transistor Q4, so that Q4 is turned on. At this time, a path is formed between the collector and the emitter of Q4, and the current flows to the base of the transistor Q5 through the resistor R21, driving Q5 to turn on. The transistor Q5 can play a driving role. When Q5 is turned on, a path is formed between its collector and the emitter, and the first end of the motor U5 is connected to the power supply VDD, and the current also flows to the base of the transistor Q6 through the diode D3. Transistor Q6 is in the amplification state, and can control the current to be constant in the circuit to protect the circuit and increase the service life of components. After the base of Q6 receives the current from Q5, Q6 is turned on, and a path is formed between its collector and emitter. The second end of motor U5 is connected to the power supply VDD, thereby completing the drive of the motor. Diode D2 and diode D3 can protect the circuit. Diodes D2 and D3 protect the base of the transistor in the circuit to prevent excessive voltage or reverse voltage from damaging the transistor.

[0088] In this embodiment, through the switching characteristics and amplification of the transistor, the driving module 103 can efficiently and quickly drive the motor to work and realize accurate motor control. Diodes D2 and D3 play a protective role in the circuit, which can effectively prevent excessive voltage or reverse voltage from damaging the transistor, thereby improving the reliability and safety of the circuit. Through the control signal output by the control module 102, the running state of the motor can be flexibly controlled, such as starting, stopping, forward rotation and reverse rotation.

[0089] like Figure 2 As shown, in one embodiment of the present disclosure, a weighing system of a slicer further includes:

[0090] Communication module 106 and display module 107 .

[0091] The communication module 106 is connected to the control module 102 . The communication module 106 is configured to receive data information and instruction information from the control module 102 , and transmit the received information to the display module 107 .

[0092] The display module 107 is connected to the communication module 106 , and the display module 107 is configured to receive and display monitoring information.

[0093] In this embodiment, when the first weight monitoring module 101 and the second weight monitoring module 105 detect data changes, the data are transmitted to the control module 102. These data reflect the real-time load of the slicer or the weight of the slice. The control module 102 can process these data. The communication module 106 can receive the data information and instruction information sent by the control module 102. The data information may include the weight information of the slices to be cut and the weight information of the sliced ​​slices, and the instruction information may be an operation instruction issued by the control module 102, such as starting, stopping or adjusting certain parameters of the slicer. When the communication module 106 receives this information, it can immediately transmit this information to the display module 107. The display module 107 is a window for the user to interact with the weighing system. It can receive information from the communication module 106 and display it to the user in an intuitive way. For example, the display module 107 can display the weight of the current slice, the state of the slicer (such as running, standby, etc.), the number of cuts of the slicer, and the cutting frequency.

[0094] For example, a food processing plant uses a slicer to slice meat. In order to ensure that the quality and weight of the slices meet the requirements, the plant introduces a weighing system for the slicer. During the production process, the weighing sensor monitors the load changes of the slicer and the weight changes of the sliced ​​meat in real time, and transmits the data to the control module 102. The control module 102 processes the data and sends the results to the display module 107 through the communication module 106. The user can intuitively see the weight of the current slice, the operating status of the slicer and other information through the display module 107. When the weight of the slice does not meet the requirements, the worker can make corresponding adjustments according to the prompts on the display module 107, such as changing the slicing speed or thickness of the slicer. The factory can also connect the weighing system with other equipment to realize automatic recording and analysis of data. Through the analysis of historical data, the factory can better understand the performance and production efficiency of the slicer and provide optimization suggestions for future production.

[0095] This embodiment can capture the weight change of the slicer in real time and immediately transmit the information to the user, ensuring that the user can understand the status of the slicer in time. Through the high-precision weighing sensor and control module 102, the system can provide accurate weight data to help the user accurately control the slicing process. The user can easily view various information of the slicer through the display module 107 without complicated operations or professional equipment. The design of the communication module 106 enables the system to be connected with other devices or systems to achieve data sharing and exchange, providing possibilities for future expansion.

[0096] like Figure 2 As shown, in one embodiment of the present disclosure, a weighing system for a slicer further includes: an alarm module 108 . The alarm module 108 is connected to the control module 102 .

[0097] In this embodiment, the alarm module 108 is connected to the control module 102 and can receive instruction information from the control module 102. When the control module 102 detects that the load of the slicer or the slice weight exceeds a preset threshold, a trigger signal can be sent to the alarm module 108. After receiving the signal, the alarm module 108 can immediately start the alarm function, such as emitting an alarm signal such as a sound or a signal light, to remind the operator to pay attention to abnormal conditions.

[0098] For example, when the load data of the slicer, that is, the weight information of the meat slices to be cut is less than the preset threshold, for example, 500g of beef needs to be cut, but the weight of the meat slices to be cut is 200g, and the meat slices are insufficient, the alarm module 108 is triggered to alarm, reminding the staff to replenish the meat slices in time. When the weight of the meat slices is 0, the control module 102 can also drive the motor to stop working.

[0099] This embodiment improves production safety. When the slicer load or slice weight is abnormal, an alarm can be quickly issued to remind the staff to replenish materials in time. At the same time, potential safety accidents can be avoided to ensure smooth production. By timely discovering and handling abnormal situations, production losses caused by shutdown maintenance or product quality problems are reduced.

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.
