[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0032] It should be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] Furthermore, in the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] by Figures 1 to 3Taking an example, this application provides a packaging oil accessory detection system. The packaging oil accessory detection system includes at least one ring lifting detection device 1 located at the outlet of a ring pressing machine on a packaging oil production line. The number of ring lifting detection devices 1 can be one or more. Each ring lifting detection device 1 includes a frame 11, a position sensor 10, and a detection assembly 2 mounted on the frame 11. The frame 11 is located on at least one side of the conveyor belt 3 at the outlet of the ring pressing machine. When there are multiple ring lifting detection devices 1, the frame 11 of each ring lifting detection device 1 can be located on the same side of the conveyor belt 3 at the outlet of the ring pressing machine, or on opposite sides of the conveyor belt 3, depending on actual needs. The position sensor 10 can be used to determine when the packaging oil on the conveyor belt 3 enters the detection area of ​​the detection assembly 2. The detection assembly 2 may include a swing arm 21 and a detector 22. A fixed shaft 110 is provided on the frame 11. The middle section of the swing arm 21 is sleeved on the fixed shaft 110 so that the swing arm 21 can rotate along the axis of the fixed shaft 110. Figure 2 As shown, Figure 2 The diagram shows that the swing arm 21 rotates clockwise under the action of the packaging oil lifting ring 30, and its rotation around the axis is the aforementioned fixed axis 110. Further, the swing arm 21 has a top end 21a located on one side of the detector 22 and a bottom end 21b opposite to the top end 21a. The bottom end 21b can abut against the packaging oil lifting ring 30 on the conveyor belt 3 when the packaging oil enters the detection area and is lifted by the packaging oil lifting ring 30 as it moves. When the bottom end 21b is lifted, the top end 21a can rotate from outside the detection range 22a of the detector 22 to within its detection range 22b to trigger the detector 22. After the bottom end 21b disengages from the packaging oil lifting ring 30, it rotates back to outside the detection range 22a of the detector 22. The triggering of the detector 22 generates a lifting ring presence signal, which can be understood as the detection result of the lifting ring detection device 1 indicating that the packaging oil lifting ring 30 is not missing and is installed correctly. If the packaging oil lifting ring 30 is missing or improperly installed, after the position sensor 10 determines that the packaging oil on the conveyor belt 3 has entered the detection area of ​​the detection component 2, the swing arm 21 will remain in its original natural state or will not be able to be lifted and deflected into the detection range 22b of the detector 22. Ultimately, the detector 22 will not be triggered to generate a lifting ring in-position signal, and the detection result will be that the packaging oil lifting ring 30 is a defective product, which can issue a chain stop command. Understandably, the packaging oil accessory detection system may also include a control terminal that is signal-connected to all lifting ring detection devices 1, and this control terminal may be further signal-connected to the position sensor 10 and the detector 22 in each lifting ring detection device 1.

[0036] It should be noted that when the top end 21a is lifted by the bottom end 21b, it can rotate from outside the detection range 22a of the detector 22 to within its detection range 22b to trigger the detector 22. This can be understood as the detector 22 and the top end 21a of the swing arm 21 being mutually detectable and sensing elements. For example, if the top end 21a of the swing arm 21 is made of metal, the detector 22 can be configured as a metal detector 22; if the top end 21a of the swing arm 21 is a light-emitting component, the detector 22 can be configured as a light detector 22; if the top end 21a of the swing arm 21 is a heat-generating component, the detector 22 can be configured as a temperature-sensing detector 22, and so on. The specific configuration of the detector 22 and the swing arm 21 can be implemented according to the actual situation.

[0037] By installing the aforementioned packaging oil accessory detection system on the packaging oil production line, the packaging oil lifting ring 30 can be automatically detected by the lifting ring detection device 1, reducing the labor intensity of workers and avoiding the risk of missed detection. Meanwhile, the detection component 2 includes a swing arm 21 and a detector 22. Through a reasonable arrangement of the relative positions of the swing arm 21 and the detector 22, the bottom end 21b of the swing arm 21 can abut against the packaging oil lifting ring 30 on the conveyor belt 3 and be lifted by the packaging oil lifting ring 30 when it moves. When the bottom end 21b is lifted, the top end 21a can rotate from outside the detection range 22a of the detector 22 to within its detection range 22b to trigger the detector 22. After the bottom end 21b disengages from the packaging oil lifting ring 30, it rotates back to outside the detection range 22a of the detector 22. This reasonable structural design ensures the stability and accuracy of the detection component 2. Furthermore, the detection component 2 has a simple structure, is easy to maintain, and is suitable for various types of packaging oil production lines, exhibiting strong versatility and adaptability.

[0038] In one embodiment of this application, please refer to Figure 1 The axis of the fixed shaft 110 extends parallel to the belt plane 31 of the conveyor belt 3 and perpendicular to the conveying direction 300 of the conveyor belt 3, which facilitates the arrangement of the fixed shaft 110 and the swing arm 21.

[0039] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The swing arm 21 is sleeved on the fixed shaft 110 at one-third of its distance from its top 21a. The rotation and reset are achieved by the weight of the swing arm 21 itself. That is, after the swing arm 21 is lifted and deflected, when the packaging oil lifting ring 30 continues to move along the conveying direction 300, it will disengage from the swing arm 21. The swing arm 21 can return to its original position by its own weight. The original position can be a vertical state (i.e., perpendicular to the belt plane 31 of the conveyor belt 3). The structure is simple and the swing arm 21 is easy to process and assemble.

[0040] Another implementation is that the rotational reset of the rocker arm 21 relies on an elastic element, such as a torsion spring, disposed between the rocker arm 21 and the fixed shaft 110. The specific arrangement is not limited here. As long as the automatic reset of the rocker arm 21 can be achieved, it should fall within the protection scope of this implementation of the application.

[0041] In one embodiment of this application, please refer to [the relevant documentation]. Figure 1 and Figure 2 The swing arm 21 has a long, strip-shaped structure and a sleeve portion 211 that is fitted onto the fixed shaft 110. The portion of the swing arm 21 between the sleeve portion 211 and the bottom end 21b includes an extension portion 212 and an abutment portion 213 located at the bottom of the extension portion 212. The bottom end 21b of the swing arm 21 abuts against the packaging oil lifting ring 30 via the abutment portion 213 and is lifted by the packaging oil lifting ring 30. Specifically, the extension portion 212 and the abutment portion 213 can be integrally formed or can be independent components connected by a locking element. The abutment portion 213 can be a component with a regular cross-section such as a circle, square, or hexagon, or its cross-section can be irregular or other irregular shapes. The swing arm 21 has a simple structure, is easy to manufacture, and can reliably abut against and be lifted by the packaging oil lifting ring 30, achieving stable and reliable power transmission and helping to further ensure the accuracy of the test results.

[0042] In one embodiment of this application, please refer to Figure 1 and Figure 2 The portion of the rocker arm 21 between the top end 21a and the sleeve portion 211 is configured as a twisted plate structure, such that the plane of the sleeve portion 211 is perpendicular to the plane of the top end 21a; optionally, the rocker arm 21 is configured as Figure 2 The twisted plate-like structure shown is easy to process; the plane where the sleeve part 211 is located is perpendicular to the plane where the top end 21a is located, which helps to ensure that the working area of ​​the sleeve part 211 and the top end 21a is sufficient at the same time. In other words, the sleeve part 211 has enough working area to be stably connected to the fixed shaft 110, and the top end 21a of the swing rod 21 has enough working area to be captured by the detector 22 in time after falling into the detection range 22b of the detector 22, and thus triggered.

[0043] In one embodiment of this application, the swing arm 21 is a stainless steel swing arm 21, which has a long service life, is not easy to rust, and has good stability when used with the detector 22.

[0044] In one embodiment of this application, the system further includes a label detection device 4 located at the labeling machine on the packaged oil production line and used for detecting the packaged oil labels, thereby improving the system's functional versatility. For a specific implementation, please refer to... Figure 3The label detection device 4 may include a position detection element 45, a diffuse reflection photoelectric switch 41, a control module 42 connected to the position detection element 45 and the diffuse reflection photoelectric switch 41 respectively, and an alarm module 43 connected to the control module 42. The position detection element 45 is used to determine whether the packaging oil at the labeling machine has entered the detection area of ​​the diffuse reflection photoelectric switch 41. That is, when the position detection element 45 detects that the packaging oil at the labeling machine has entered the detection area of ​​the diffuse reflection photoelectric switch 41, it can send a corresponding signal to the control module 42. If the control module 42 receives a label presence signal from the diffuse reflection photoelectric switch 41, it can determine that the label is not missing. If the control module 42 does not receive a label presence signal from the diffuse reflection photoelectric switch 41, it can determine that the label is missing. At this time, the control module 42 can send an alarm command to the alarm module 43 to trigger an alarm, so as to notify the staff to deal with the label missing in time. The alarm can be an audible and visual alarm or other alarm methods, which are not limited here. The control terminal or control module 42 mentioned above can be a programmable logic controller (PLC).

[0045] In one embodiment of this application, please refer to [the relevant documentation]. Figure 3 The label detection device 4 also includes a switch assembly 44 that is signal-connected to the control module 42 and used to control the labeling machine switch. That is, when the control module 42 determines that a label is missing, it can send a stop command to the switch assembly 44 used to control the labeling machine switch so that the staff can stop the machine to check and handle the label missing incident in a timely manner.

[0046] In one specific implementation, this application employs sensor technology and control algorithms to monitor the label and lifting ring status of packaged oil products on the packaging oil production line in real time. When a label or lifting ring is detected to be missing, the system can automatically issue a stop command and cut off the power supply through an interlocking stop device, thus safely shutting down the production line.

[0047] Specifically, it mainly consists of a sensor section, a control section, and an execution section. The sensor section is responsible for real-time monitoring of the equipment's operating status; the control section determines whether a shutdown is necessary based on sensor data and issues a shutdown command; the execution section receives commands from the control section, cuts off the power, and stops the production line. The sensor section can collect real-time operating data from the equipment through detection units installed at various key locations on the production line. Specifically, the core detection component of the label loss detection device can be a diffuse reflection photoelectric switch 41, which emits a beam of light onto the label using a light source such as an LED or laser diode, and then verifies the presence or absence of the label based on the strength of the received electrical signal. Furthermore, the diffuse reflection photoelectric switch 41 can be installed inside the labeling machine, using it to detect and compare various characteristics of the packaged oil, such as firstly detecting whether the oil bottle has entered the detection area, and secondly detecting whether the oil bottle in the detection area has a label affixed. The PLC judges the strength of the sampled signal, outputs an audible / visual alarm indication for a missing label, and outputs a relay control signal to delay shutdown, facilitating timely handling by operators. The aforementioned control unit receives data transmitted from the sensor unit and analyzes it based on preset thresholds and algorithms. When a fault or abnormal condition is detected in the equipment, a stop command is immediately issued. The aforementioned execution unit receives the stop command from the control unit and cuts off the power supply via relays and other components, safely halting the production line. Simultaneously, an alarm signal is sent to the operator, prompting them to take appropriate action.

[0048] The packaging oil accessory testing system proposed in this application can effectively improve the automation level and safety of packaging oil production lines. Specifically, it improves in the following aspects:

[0049] (1) The machine sensor technology and control algorithm used in this application can realize real-time monitoring and intelligent judgment of the product label and lifting ring status on the packaging oil production line.

[0050] (2) Through the design of the interlocking shutdown device, the automatic shutdown function is realized when the label or lifting ring is missing, which effectively prevents the outflow of unqualified products and the occurrence of product quality accidents.

[0051] (3) It has a simple structure and is easy to maintain. It is suitable for various types of packaging oil production lines and has strong universality and adaptability.

[0052] This application discloses a packaged oil production line, including a ring pressing machine and the aforementioned packaged oil accessory detection system. The packaged oil accessory detection system includes at least one ring lifting detection device 1 located at the outlet of the ring pressing machine. Alternatively, it may include at least one label detection device 4. It should be noted that the sensitivity and threshold parameters of the sensors in the ring lifting detection device 1 and the label detection device 4 can be adjusted according to the actual conditions of the packaged oil production line to ensure that the packaged oil accessory detection system can accurately determine the accessory status and issue a stop command in a timely manner.

[0053] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
