These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] 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, not all, of the embodiments of the present invention. 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.

[0036] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the packaging machine includes a bag insertion structure 1. During normal operation, the bag insertion structure 1 moves along a first direction (e.g., ...). Figure 1 (As indicated by the arrow) Reciprocating motion; when the packaging machine is in standby mode, the bag insertion structure 1 stops moving; the alarm device includes a detection structure and an alarm, the detection structure is used to detect whether the bag insertion structure 1 has stopped moving, and the detection structure and the alarm are electrically connected.

[0038] Furthermore, in this embodiment, the operating state of the bag insertion structure 1 changes with the operating state of the packaging machine. By detecting the movement state of the bag insertion structure 1, the operating state of the packaging machine can be obtained intuitively. When the packaging machine is in standby mode, it can promptly alert the staff, enabling them to adjust the packaging machine in a timely manner, thereby improving production efficiency and reducing energy consumption.

[0039] Preferably, the detection structure includes a control unit and a detection element 2; the detection element 2 is installed on the packaging machine and is used to detect the position of the insert bag structure 1; the detection element 2 and the control unit are electrically connected, the control unit is used to receive feedback information from the detection element 2 and determine whether the insert bag structure 1 has stopped moving, and the alarm is electrically connected to the control unit.

[0040] Furthermore, such as Figure 1 As shown, the detection element 2 is located on the right side of the insert bag structure 1, with the first direction being the horizontal direction indicated by the arrow. The insert bag structure 1 moves horizontally towards or away from the detection element 2. In this embodiment, the detection element 2 is a photoelectric sensor. The insert bag structure 1 moves from the initial position to the final position along the first direction; the detection element 2 is mounted on the packaging machine, and its movement path relative to that of the insert bag structure 1 from the initial position to the final position is arranged accordingly. Figure 1 As shown, the insert bag structure 1 is in its initial position. The insert bag structure 1 moves to the right until it reaches its maximum reachable distance, which is the endpoint position. The detection element 2 is positioned on the path from the initial position to the endpoint position. The insert bag structure 1 moves from the initial position to the endpoint position and then returns from the endpoint position to the initial position, thus completing one work cycle. A third time is set in the control unit. When the detection element 2 detects that the insert bag structure 1 has passed the detection element 2, the control unit starts timing. If the time taken for the insert bag structure 1 to pass the detection element 2 is less than or equal to the third time, the control unit determines that the packaging machine is in normal operation. Depending on the running speed of the insert bag structure 1 and the distance between the detection element 2 and the initial position of the insert bag structure 1, the third time in this embodiment is 5-15 seconds. If the time taken for the insert bag structure 1 to pass the detection element 2 is greater than the third time, the control unit determines that the packaging machine is in standby mode.

[0041] Preferably, the control unit includes a first switch and a first time; the control unit is used to control the first switch to close when the detection element 2 does not detect the insert structure 1, and the control unit is used to determine that the packaging machine is in standby mode and control the alarm to sound when the closing time of the first switch is greater than the first time.

[0042] Preferably, the control unit includes a second switch; the first switch, the second switch, and the alarm are connected in series, and the control unit is used to control the second switch to close when the closing time of the first switch is greater than a first time, and the alarm sounds when the second switch is closed.

[0043] Furthermore, such as Figure 1 As shown, the control unit includes an intermediate relay KA1 and a time relay KT2. Intermediate relay KA1 includes contacts 3 and 11, and time relay KT2 includes contacts 15 and 16. A first switch connects to contacts 3 and 11, and a second switch connects to contacts 15 and 16. The alarm, the first switch, and the second switch are connected in series. When the detection element 2 does not detect the insert structure 1, the control unit controls the first switch to close, energizing the coil of time relay KT2 and starting the timer. When the timer duration of time relay KT2 exceeds a first time, the control unit determines that the insert structure 1 has stopped moving, the packaging machine is in standby mode, the control unit controls the second switch to close, and the alarm sounds.

[0044] Preferred, such as Figure 3 As shown, the control unit includes a control interface with a first input box for setting a first time. In this embodiment, the control unit sets an initial value, and the control interface has "+" and "-" buttons. The duration of the first time can be increased by clicking the "+" button, and the duration of the first time can be decreased by clicking the "-" button.

[0045] Preferably, the control unit includes a third switch and a second time; the control unit is used to control the third switch to close when the detection element 2 detects the insert structure 1, and the control unit is used to determine that the packaging machine is in standby mode and control the alarm to sound when the closing time of the third switch is greater than the second time.

[0046] Preferably, the control unit includes a fourth switch; the third switch, the fourth switch, and the alarm are connected in series, and the control unit is used to control the fourth switch to close when the closing time of the third switch is greater than the second time, and the alarm sounds when the fourth switch is closed.

[0047] Furthermore, such as Figure 2 As shown, the intermediate relay KA1 also includes contacts 2 and 6, the time relay KT1 includes contacts 17 and 18, the third switch is connected to contacts 2 and 6, and the fourth switch is connected to contacts 17 and 18. The alarm, the third switch, and the fourth switch are connected in series. When the detection element 2 detects the insert structure 1, the control unit controls the third switch to close, the coil of the time relay KT1 is energized, and the time relay KT1 starts timing. When the timing time of the time relay KT1 exceeds a second time, the control unit determines that the insert structure 1 stops moving, the packaging machine is in standby mode, the control unit controls the fourth switch to close, and the alarm starts sounding.

[0048] Preferred, such as Figure 3As shown, the control unit includes a control interface with a second input box for setting a second time. In this embodiment, an initial value is set in the control unit, and "+" and "-" buttons are provided on the control interface. The duration of the second time can be increased by clicking the "+" button, and the duration of the second time can be decreased by clicking the "-" button.

[0049] Furthermore, the control unit sets a third time, which controls the third switch to close when the time for the detection element 2 to detect the pocket structure 1 is greater than the third time.
