[0019] Among them, the power switch of the equipment is electrically connected (power supply connected) to the transformer and the servo system respectively, so that the external power supply can be normally powered on and off with the transformer and the servo system. When the power switch of the equipment is connected to the external power supply and the external power supply is normally powered on, the external power supply can normally supply power to the transformer and the servo system. The power switch of the equipment can be shared or configured independently according to needs. Among them, the transformer power supply is connected to the PLC controller.

Working components such as the embracing working component, the rolling mouth working component, the rolling bottom working component, the knurling working component, the bottom making working component, the turntable working component, the cup discharging working component, etc.

[0022] Referring to the accompanying drawings, in the embodiment of the present embodiment, the startup and power-off braking method of the paper cup machine (i.e., the startup and power-off braking device of the paper cup machine) is connected to an external power supply (such as a plant power supply, a power company grid power supply, etc.) by connecting the power switch of the equipment;

[0023] The external power supply is connected to the transformer and the servo system for normal power supply on and off through the equipment power switch. The equipment power switch is used for normal power supply on and off between the transformer and the servo system and the external power supply;

[0024] The transformer is connected to the PLC controller and cooperates to supply power to the PLC controller normally, and cooperates to supply power input from the external power supply to the transformer to the PLC controller;

[0025] The PLC controller is connected to the servo system and controls the servo system. The servo system cooperates with the control motor group to operate, so that the PLC controller can control (manipulate) the servo system to cooperate with the control motor group to operate. The PLC controller controls the motor group to operate through the servo system;

[0026] Therefore, when the external power supply is normally powered on, it can supply power to the PCL controller and the servo system, cooperate with the control motor group to operate, and provide driving power and braking power to the cup machine working group, so that the paper cup machine can start and operate normally.

[0027] The PLC controller not only controls the servo system to control (i.e., manipulate) the operation of the motor group, but also connects to the backup power supply, wherein: when the external power supply is normally powered on, the PLC controller receives a power-on signal and controls the charging and energy storage of the backup power supply, and can charge and store energy for the backup power supply, and when the external power supply is normally powered on, it can normally supply power to the servo system, transformer, and PLC controller, and the motor group operates normally under the coordinated control of the servo system and the PLC controller, and normally provides driving power and braking power to the cup machine working group; when the external power supply is suddenly disconnected, the PLC controller receives a power-off signal and controls the backup power supply to supply power to the PLC controller and the servo system respectively, so that when the external power supply is suddenly disconnected (such as power outage, failure, misoperation, etc.), the backup power supply can provide power to the PLC controller and the servo system, so that the PLC controller and the servo system can continue to operate, so that it can cooperate with the control of the motor group to provide the required braking power to the cup machine working components, so that the cup machine working group in the paper cup machine can be stably shut down, and avoid the problem of confusion in coordination and destruction of coordination between the cup machine working components after a sudden power outage; so that the paper cup machine can be powered off and braked to stop.

[0028] Among them, the motor group is controlled by the PLC controller through the servo system, and the PLC controller and the servo system (such as the servo controller) can realize the control connection through the communication connection to control the operation of the motor group, and the motor group provides the required driving power (so that the cup machine working component can operate normally) and the required braking power (so that the cup machine working component can stop stably) to the cup machine working component. The motor group corresponds to the transmission connection cup machine working group.

[0029] The device and method have the following effects: a backup power supply is configured in the paper cup machine, and when the paper cup machine and the external power supply are normally powered on, the PCL controller and the servo system can be powered normally, and the operation of the control motor group can be coordinated to provide driving power and braking power to the cup machine working group normally. The PLC controller receives a power-on signal and controls the charging and energy storage of the backup power supply, and can charge and store energy for the backup power supply; in addition, when the paper cup machine and the external power supply are suddenly disconnected, the PLC controller receives a power-off signal and controls the backup power supply to supply power to the PLC controller and the servo system respectively, so that the PLC controller and the servo system can continue to operate, thereby being able to cooperate with the control motor group to provide the required braking power to the cup machine working components, so that the cup machine working group in the paper cup machine can be stably stopped, braked and decelerated to stop stably, and ensure that the shutdown (position) of each cup machine working component is accurate and stable, avoiding the problem of confusion in coordination and destruction of coordination between the cup machine working components after a sudden power outage. No matter the external power supply is normally on or suddenly disconnected, the working components of the cup machine can shut down smoothly and stably, and the coordination between the working components of the cup machine will not be disrupted and the coordination will remain consistent, thus avoiding the risk of sudden power failure causing the coordination between the working components of the cup machine to be disrupted, the coordination to be destroyed, and even the risk of collision.

[0030] It is found in the present invention that under normal operation (especially during high-speed operation), when the external power supply is suddenly disconnected, the paper cup machine cannot stop the working components of each cup machine immediately due to the inertia of movement, and has different inertia displacements, which leads to deviations in the stopping (stop position) of the working components of the cup machine, confusion in the coordination between the working components of the cup machine, destruction of the coordination of the production equipment, and the existence of the risk of collision; in the present invention, when the external power supply is suddenly disconnected, the backup power supply will supply power to the PLC controller and the servo system respectively, so that the PLC controller and the servo system can continue to operate, so as to cooperate with the control motor group to provide the required braking power to the working components of the cup machine, and offset the inertia of the working components of the cup machine through braking deceleration, so that the working group of the cup machine in the paper cup machine can be stably stopped without inertia displacement, avoiding confusion in the coordination and destruction of the working components of the cup machine after a sudden power failure, and there is no risk of collision.

[0031] The following optimization or further explanation may be performed based on the above embodiments.

[0032] For example, the PLC controller has a servo control module, and the servo control module is connected to the servo system control, so that the PLC controller controls the servo system through the servo control module, so that the servo system can control the motor group. The PLC controller has a power control module, and the power control module includes a power-on energy storage charging part and a power-off energy consumption reverse charging part, and the power-on energy storage charging part and the power-off energy consumption reverse charging part are respectively connected to the backup power supply control. So that the PLC controller can control the charging of the backup power supply when the external power supply is normally powered on by the power-on energy storage charging part, and the PLC controller can charge and store energy for the backup power supply when it receives a power-on signal. So that the PLC controller can control the charging of the backup power supply when the external power supply is suddenly disconnected by the power-off energy consumption reverse charging part, and the PLC controller can control the backup power supply to supply power to the PLC controller and the servo system respectively, so that the PLC controller and the servo system can cooperate to control the motor group to provide braking power to the working components of the cup machine. The servo control module and power control module (including the power-on energy storage and charging part and the power-off energy consumption and reverse charging part) of the PLC controller are mature technologies. The technical problem solved in the utility model is not to improve the specific modules, but to use the modules to cooperate with each other to solve the problem, so that after a sudden power outage, the working components of the cup machine will not be confused in coordination and the coordination will not be destroyed.

[0033] Among them, when the external power supply is normally powered on, the PLC controller receives the power-on signal and controls the charging and energy storage of the backup power supply;

[0034] When the external power supply is suddenly disconnected, the PLC controller receives a power-off signal and controls the backup power supply to supply power to the PLC controller and the servo system respectively.

[0035] Among them, the PLC controller controls the connected servo system, the servo system cooperates with the control motor group to drive the cup machine working component to operate normally, and the servo system cooperates with the control motor group to brake the cup machine working component to decelerate and stop stably (braking stable shutdown).
