[0025] Please combine Figure 1 and Figure 2 A safety reminder device 1 based on a micro switch provided in the first embodiment of the utility model is used to control the closing of the door panel of the printing line inkjet printer, including a main control module 10, a power module 11 and a micro switch 12. The main control module 10 is connected to the micro switch 12 signal and is electrically connected to the power module 11. The micro switch 12 is a telescopic mechanism, which includes a conductor 120 and a telescopic rod 121. The telescopic rod 121 is sleeved in the conductor 120. One end of the conductor 120 away from the telescopic rod 121 is fixedly connected to the main control module 10. The telescopic rod 121 approaches or moves away from the door panel of the printing line inkjet printer to open or close the door panel of the printing line inkjet printer.

[0026] As an optional embodiment, a buffer spring is arranged between the telescopic rod 121 and the conductor 120. This arrangement enables the telescopic rod 121 to have a spring with good elasticity and buffering performance, and the spring is arranged between the two, which can absorb impact, reduce vibration, and maintain stability. When the telescopic rod 121 is impacted by external force during the extension and retraction process, the buffer spring can deform quickly, absorb part of the impact energy, and protect the telescopic rod 121 and the conductor 120 from damage; at the same time, the buffer spring can also alleviate the stress fluctuation caused by the change in the length of the telescopic rod 121, thereby improving the stability of the entire device.

[0027] For better explanation, the printing line inkjet printer refers to a machine that uses high-precision inkjet technology to print various exquisite patterns on the shoe surface. It enables shoemaking companies to quickly, efficiently and flexibly produce shoes with personalized patterns to meet the needs of the market and consumers; and the safety reminders for door panels prevent accidental injuries to operators due to improper operation.

[0028] It can be understood that the main control module 10, the power module 11 and the micro switch 12 cooperate to realize the safety reminder of the line printing inkjet printer and prevent safety hazards to the operator; wherein, the main control module 10 is responsible for receiving and processing the information of the micro switch 12, and the power module 11 is connected with the line printing inkjet printer and the micro switch 12, that is, the power module 11 is combined with the micro switch 12 to send a safety reminder signal to the operator, and the telescopic cooperation between the conductor 120 and the telescopic rod 121 can realize the switch operation. This setting effectively improves the safety performance of the line printing inkjet printer. When the operator opens the door panel when it should not be opened, the micro switch 12 makes corresponding processing to remind the operator to pay attention and prevent safety accidents caused by improper operation. The device has a simple structure and ensures the personal safety of the operator.

[0029] Furthermore, a clamping structure 122 is provided at one end of the conductor 120 close to the telescopic rod 121 , and an annular clamping portion 123 is provided on the telescopic rod 121 corresponding to the clamping structure 122 , and the clamping structure 122 is clamped with the annular clamping portion 123 .

[0030] It is explained that the clamping structure 122 and the annular clamping portion 123 cooperate with each other to make the connection between the two more secure and achieve precise positioning, so that the telescopic rod 121 can extend and retract more smoothly and stably without losing its performance; and when subjected to external force impact, the clamping structure 122 can effectively absorb energy and reduce the impact of the impact on the telescopic rod 121; specifically, when the telescopic rod 121 is impacted by the buffer spring, it moves away from the main control module 10, and as the buffer spring is subjected to force, the clamping structure 122 and the annular clamping portion 123 are clamped to confine the telescopic rod 121 within the conductor 120.

[0031] Furthermore, when the door panel approaches and abuts against the telescopic rod 121 , the door panel presses the telescopic rod 121 into the conductor 120 and abuts against the main control module 10 , and the power module 11 is closed.

[0032] Furthermore, when the door panel moves away from the telescopic rod 121 , the telescopic rod 121 pops out from the conductor 120 , and the clamping structure 122 is clamped with the annular clamping portion 123 , and the power module 11 is disconnected.

[0033] To explain, the door panel presses the telescopic rod 121 to make it enter the conductor 120, and the telescopic rod 121 is in contact with the door panel and the main control module 10. At this time, the power module 11 is closed to ensure the connectivity of the circuit and provide power for subsequent inkjet printing work; when the door panel is away from the telescopic rod 121, operations such as changing ink or repairing the machine may be required. At this time, the telescopic rod 121 pops out from the conductor 120, and the telescopic rod 121 is clamped in the conductor 120 through the cooperation of the clamping structure 122 and the annular clamping part 123, and the power module 11 is disconnected to prevent the line printing machine from continuing to run and affecting the safety of the operator.

[0034] Furthermore, the main control module 10 includes a relay 100 for controlling the extension and retraction frequency of the telescopic rod 121 in the conductor 120 .

[0035] It can be explained that the main control module 10 is responsible for controlling and managing the operation of the micro switch 12, and the relay 100 uses the electromagnetic principle. When the current at the input end reaches the set value, the relay 100 will generate a magnetic field, thereby attracting the contacts at the output end to change. This change can control the expansion and contraction frequency of the telescopic rod 121 in the conductor 120, and the relay 100 has high reliability, fast response speed, and easy operation. In addition, the relay 100 has a certain anti-interference ability so that the equipment can still operate normally under complex environmental conditions; this setting enables the telescopic rod 121 to be replaced in time when it reaches the expansion and contraction frequency threshold, thereby ensuring the stability of the micro switch 12 and avoiding damage to the micro switch 12 and affecting the safe operation of the line printing machine.

[0036] Furthermore, the main control module 10 also includes a warning mechanism 101 , which is connected to the main control module 10 by signal. When the door panel is away from the micro switch 12 , the warning mechanism 101 uses light to give a warning.

[0037] It is explained that the warning mechanism 101 is connected to the main control module 10 through signals to form a collaborative whole; when the door panel leaves the detection range of the micro switch 12, the telescopic rod 121 pops out, and the warning mechanism 101 sends a reminder signal to the user through flashing lights. This setting is both intuitive and eye-catching, and can effectively prevent users from accidentally operating the line printing machine without knowing it.

[0038] Furthermore, the signal connection mode of the main control module 10 is any one of Bluetooth and wireless radio frequency communication.

[0039] It is explained that in order to meet the needs of wireless communication, the main control module 10 adopts either Bluetooth or wireless radio frequency communication. Among them, Bluetooth, as a short-range wireless communication technology, has been widely used in the connection and data transmission between various electronic devices. It has the advantages of low cost, low power consumption, and high reliability, so that devices can easily exchange data and work together. Wireless radio frequency communication transmits data through radio waves, and has the characteristics of long signal transmission distance, strong anti-interference ability, and high transmission rate.

[0040] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
