[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] See Figure 1-9 This utility model provides a low-voltage DC motor round bottle labeling machine, which includes a touch switch module 10, a main control module 20, a label detection module 30, a power supply module 40, and a motor drive module 50. The touch switch module 10, the main control module 20, the label detection module 30, and the motor drive module 50 are all connected to the power supply module 40, and the touch switch module 10, the label detection module 30, and the motor drive module 50 are all connected to the main control module 20.
[0033] The main control module 20 receives the touch signal sent by the touch switch module 10, and the main control module 20 controls the motor drive module 50 to drive the motor connected to the motor drive module 50 to operate according to the touch signal.
[0034] When the main control module 20 receives the tag sensing signal sent by the tag detection module 30, the main control module 20 controls the motor drive module 50 to drive the working state of the motor according to the tag sensing signal.
[0035] In this embodiment, as Figure 7 As shown, the motor drive module 50 includes a first optocoupler 51, an amplifier circuit 52, and a relay 53 connected to the main control module 20. Both the first optocoupler 51 and the relay 53 are connected to the amplifier circuit 52. The first optocoupler 51 receives control commands from the main control module 20, and the amplifier circuit 52 processes the control commands and controls the relay 53 to engage. Figure 3 As shown, the main control module 20 includes a chip U2 of model STM32F103C6T6, and the touch switch module 10 includes a second optocoupler 11 and a switch unit 12. Both the main control module 20 and the switch unit 12 are connected to the second optocoupler 11. The switch unit 12 inputs the touch signal to the main control module 20 through the second optocoupler 11. The switch unit 12 includes a micro switch, a foot switch, or an external switch. Figure 4 As shown, the label detection module 30 includes a label sensor 31 and a third optical coupler 32. The label sensor 31 and the main control module 20 are both connected to the third optical coupler 32. The third optical coupler 32 outputs the label sensing signal sent by the label sensor 31 to the main control module 20.
[0036] It should be noted that, as Figure 8 As shown, the low-voltage DC motor round bottle labeling machine also includes a first interface circuit connected to the power module 40. The touch switch module 10, the label detection module 30, and the motor drive module 50 are all connected to the first interface circuit. Figure 5 and Figure 6 As shown, the power module 40 includes a power input circuit 41 and a voltage regulator circuit 42. The tag detection module 40 and the main control module 20 are both connected to the voltage regulator circuit 42. Figure 9 As shown, the low-voltage DC motor round bottle labeling machine also includes a second interface circuit connected to the main control module 20. The touch switch module 10, the label detection module 30, and the motor drive module 50 are all connected to the second interface circuit. The voltage regulator circuit 42 includes a chip U9 with model number 78M05_C351790. When the labeling machine is working, the relay or electronic amplifier tube in the start circuit is activated by a micro switch or foot switch to drive the motor. When the label sensor 31 detects that the label is applied, the relay 53 or electronic amplifier tube is disconnected, and the two ends of the motor are quickly shorted or the series resistor is quickly shorted. The DC motor will quickly increase the resistance, thereby achieving precise stopping.
[0037] Specifically, such as Figure 2 As shown, the touch switch module 10 includes a micro switch U11, a resistor R10, and a second optocoupler U3. Pin 1 of U1 receives DC 12V, pin 2 of U11 is connected to one end of R10, the other end of R10 is connected to pin 1 of U3, pin 2 of U3 is grounded, pin 4 of U3 outputs 3.3V, and pin 3 of U3 is connected to terminal A2 of the second interface circuit. Figure 4 As shown, the tag detection module 30 includes a tag sensor U10, a resistor R11, and a third optocoupler U6. Pin 1 of U10 receives a 12V input, pin 2 of U10 is grounded, pin 3 of U10 is connected to one end of R11, and the other end of R11 is connected to pin 2 of U6. Pin 1 of U6 receives a DC 12V input, pin 3 of U6 is connected to terminal A3 of the second interface circuit, and pin 4 of U6 outputs 3.3V. Figure 8 As shown, the first interface circuit includes diode D1 and capacitor C5. The anode of D1 receives DC 12V, and the cathode of D1 is connected to capacitor C5, as shown. Figure 9As shown, the second interface circuit includes resistors R17, R15, and R14 connected in parallel; as Figure 5 As shown, the power input circuit 41 includes a power input port U19, which outputs DC 12V. Figure 6 As shown, the voltage regulator circuit 42 includes a chip U9, an inductor L1, a capacitor C1, and a capacitor C2. L1 is connected to pin 1 of the chip U9, and capacitors C1 and C2 are connected in parallel to pins 2 and 3 of the chip U9. The input power supply voltage can be below 36V, such as a DC voltage of 24V or 12V, and is not limited here; it can be set according to actual needs.
[0038] Specifically, such as Figure 3 As shown, the main control module 20 includes a chip U2 with multiple pins, such as... Figure 7 As shown, the motor drive module 50 includes a first optocoupler U5, resistors R34 and R36, an amplifier circuit Q4, a relay K2, a fuse U8, and a motor U15. One end of the fuse U8 is connected to a DC 12V input, and the other end is connected to the input terminal of the relay K2. The output terminal of the relay K2 is connected to the motor U15, diode D5, and the collector of transistor Q4. The base of transistor Q4 is connected to one end of resistor R34, and the other end of R34 is connected to pin 4 of U5. Pins 3 and 2 of U5 are connected and grounded. The emitter of transistor Q4 is connected to a DC 12V input, and pin 1 of U5 is connected to one end of resistor R36. The other end of resistor R36 is connected to terminal A5 of the second interface circuit. Diode D5 is connected in parallel to the output terminal of K2. Replacing the AC motor, stepper motor, or servo motor in the labeling machine's drive section with a DC motor, whose operating voltage is below 36V, is a safe voltage, reducing the risk of electric shock.
[0039] It should be understood that the equipment uses a low-voltage DC motor (below 36V), meaning the external power supply is directly converted to a voltage below 36V and input into the equipment. This reduces the risk of equipment wear, motor damage, and electric shock. It features low cost, small size, and high output power for the same torque DC motor. Extensive testing has shown that it generates very little heat; the use of a virtually heat-free DC motor solves the problems of the original labeling machine, which used an AC motor that overheated after a period of operation, had easily aged internal coils, or was prone to leakage under 220V conditions. By configuring a touch switch module 10, a main control module 20, a label detection module 30, a power supply module 40, and a motor drive module 50, the main control module 20 receives touch signals sent by the touch switch module 10. Based on the touch signals, the main control module 20 controls the motor drive module 50 to drive the motor connected to the motor drive module 50 to operate. When the main control module 20 receives a label sensing signal sent by the label detection module 30, the main control module 20 controls the motor drive module 50 to drive the motor's operating state based on the label sensing signal. By using a DC motor and switching the motor circuit when stopped to short-circuit the motor or connect a series resistor in the middle, the motor inertia is prevented, achieving the same or better effect as an AC motor. This makes the labeling machine control precise. The DC motor has the characteristics of small size, high output power, and low cost. The voltage is controlled within a safe range, reducing the risk of electric shock.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
