Description

Technical Field

[0001] This utility model relates to the technical field of air supply control for cigarette making machines, and more specifically, to a positive and negative pressure air supply control system for cigarette making machines. Background Technology

[0002] In the production of the POTO 70 cigarette making machine, stable air pressure is required at multiple workstations due to process requirements. The low-pressure ventilator and the paper-cutting wheel negative pressure fan are operational after the equipment is powered on, ensuring a continuous air supply. The low-pressure ventilator provides continuous positive pressure air to the air distribution device, air chamber, and blowing pipe; the paper-cutting wheel negative pressure fan provides continuous negative pressure air to the paper-cutting wheel. When the equipment stops due to faults or other reasons, the low-pressure ventilator and the paper-cutting wheel negative pressure fan often fail to shut down in time, resulting in significant waste of electrical and wind energy. Therefore, it is of great importance to achieve intelligent control to sequentially shut down the low-pressure ventilator and the paper-cutting wheel negative pressure fan to avoid idling.

Attached Figure Description

[0025] To more clearly illustrate the specific embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0026] Figure 1 This is a schematic diagram of a positive and negative pressure air supply control system for a cigarette machine provided by this utility model. Detailed Implementation

[0027] To enable those skilled in the art to better understand the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0028] To address the issues of energy waste and inconvenience caused by the need for manual control of positive and negative pressure air supply in current cigarette making machines, this utility model provides a positive and negative pressure air supply control system for cigarette making machines. This system solves the problems of energy waste and inconvenience caused by the need for manual control of positive and negative pressure air supply in existing cigarette making machines, and improves the convenience and intelligence of positive and negative pressure gas control in cigarette making machines.

[0029] like Figure 1As shown, a positive and negative pressure air supply control system for a cigarette machine includes: a PLC controller, a first drive contactor, a second drive contactor, a first energy-saving contactor, and a second energy-saving contactor. The output terminals of the three-phase power supply are connected to the input terminals of the first drive contactor and the second drive contactor, respectively. The output terminal of the first drive contactor is connected to the input terminal of the first energy-saving contactor, and the output terminal of the first energy-saving contactor is connected to the power supply terminal of a low-pressure fan. The control terminal of the first energy-saving contactor is connected to the first output terminal of the PLC controller. The output terminal of the second drive contactor is connected to the input terminal of the second energy-saving contactor, and the output terminal of the second energy-saving contactor is connected to the power supply terminal of a paper-cutting roller negative pressure fan. The coil terminal of the second energy-saving contactor is connected to the second output terminal of the PLC controller. The PLC controller is signal-connected to the cigarette machine and controls the first and second energy-saving contactors to turn on or off according to the start / stop signal of the cigarette machine, thereby correspondingly controlling the on / off electrical connection between the low-pressure fan and the paper-cutting roller negative pressure fan and the three-phase power supply.

[0030] Specifically, during normal production, the negative pressure fan of the paper-cutting roller is in operation. This operation is controlled by the second drive contactor and the second energy-saving contactor. When the operating condition is met, the coil of the second drive contactor is energized, the normally open contact of the second drive contactor is closed, and the second energy-saving contactor is simultaneously closed. This connects the three-phase power supply to the power terminal of the negative pressure fan, causing it to operate and providing stable negative pressure suction to the paper-cutting roller. This ensures that the cork paper is firmly adhered to the paper-cutting roller, guaranteeing product quality. When the machine is to be stopped, the PLC controller receives a stop command and issues a shutdown signal, causing the second energy-saving contactor to open, disconnecting the electrical connection between the three-phase power supply and the negative pressure fan of the paper-cutting roller. Correspondingly, when the PLC controller receives a start command, it controls the coil of the first drive contactor to be energized, the normally open contact of the first drive contactor is closed, and the first energy-saving contactor is turned on. This connects the three-phase power supply to the low-pressure fan, causing the low-pressure fan to operate and providing stable positive pressure airflow to the air distribution device, air chamber, and blower duct. When the PLC controller receives a shutdown command, it sends a shutdown signal to disconnect the first energy-saving contactor, thereby breaking the electrical connection between the three-phase power supply and the low-pressure fan.

[0031] When the equipment stops due to a fault or non-fault, and the cigarette machine triggers a shutdown signal, the PLC controller receives the shutdown command of the cigarette machine and controls the first and second energy-saving contactors to disconnect, cutting off the electrical connection between the paper cutting roller negative pressure fan and the low-pressure fan and the three-phase power supply. This causes the fans to stop running due to power loss until the equipment is restarted, at which point the paper cutting roller negative pressure fan and the low-pressure fan resume normal operation.

[0032] Furthermore, the first energy-saving contactor and the second energy-saving contactor are normally closed contactors.

[0033] The system also includes: a touch screen; the touch screen is signal-connected to the PLC controller, and the touch screen is equipped with a human-machine interface; the PLC controller controls the first energy-saving contactor and the second energy-saving contactor to be turned on or off according to the control commands input on the human-machine interface.

[0034] The system also includes an alarm device; the PLC controller is signal-connected to the alarm device, and if the first energy-saving contactor and / or the second energy-saving contactor are still in the conducting state within a set time after the cigarette is turned off, the PLC controller controls the alarm device to perform a fault alarm.

[0035] Furthermore, the alarm device includes at least one of the following: an indicator light, a buzzer, and an audible and visual alarm.

[0036] The system also includes: a wireless network module and a mobile terminal; the PLC controller communicates with the mobile terminal of the designated operator through the wireless network module; the PLC controller pushes alarm information to the mobile terminal when a fault alarm is triggered.

[0037] In practical applications, wireless network modules can be wireless routers or mobile communication modules.

[0038] Furthermore, the mobile terminal includes at least one of the following: smartphone, smart wearable device, and tablet computer.

[0039] Preferably, the PLC controller is also connected to the coil terminals of the first drive contactor and the second drive contactor respectively, and controls the first drive contactor and the second drive contactor to be turned on or off according to the start command or stop command input by the human-machine interface, so as to control the start or stop of the low-pressure fan and the paper cutting wheel negative pressure fan.

[0040] Furthermore, both the first and second drive contactors are normally open contactors.

[0041] Furthermore, the PLC controller controls the first energy-saving contactor to close after the first drive contactor is disconnected, and controls the second energy-saving contactor to close after the second drive contactor is disconnected.

[0042] As can be seen, this utility model provides a positive and negative pressure air supply control system for cigarette machines. A first energy-saving contactor is connected in series between a first drive contactor and a low-pressure fan, and a second energy-saving contactor is connected in series between a second drive contactor and a paper-cutting roller negative pressure fan. A PLC controller is connected to the coil terminals of the first and second energy-saving contactors respectively to control the on / off connection of the low-pressure fan and the paper-cutting roller negative pressure fan with the three-phase power supply. This solves the problem that existing cigarette machines require manual control of positive and negative pressure air supply, which easily leads to energy waste and inconvenience, and improves the convenience and intelligence of positive and negative pressure gas control in cigarette machines.
