[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] like Figure 1-Figure 2As shown, the embodiment of the present application provides a compressed air control device for a rolling and splicing machine group, which is applied to the rolling and splicing machine group of a cigarette factory, and is particularly preferably applicable to the ZJ116 type rolling and splicing machine group. During the operation of the rolling and splicing machine group, a large amount of compressed gas is required. The compressed gas is used as a power source to drive related equipment components. The system for supplying compressed gas includes a compressor and an air supply pipeline. A shut-off valve is provided on the air supply pipeline. Under the action of the shut-off valve, the air supply pipeline is turned on and off, thereby realizing the supply and cut-off of compressed gas. The shut-off valve can only realize the supply or non-supply of compressed gas. When supplying compressed gas, the supply amount of compressed gas can only maintain a certain fixed value. In the actual production process, it is found that compressed gas The redundancy of the supply system when supplying compressed gas to relevant equipment components is too high, that is, the supply of compressed gas is much higher than the standard demand of relevant equipment components. The purpose is to ensure that the relevant equipment components can operate normally. However, the excessive redundancy of the supplied compressed gas also has a negative impact, causing the compressed gas usage to seriously exceed the standard. Excessive use of compressed gas causes a certain degree of resource waste, which is not conducive to energy conservation and emission reduction. The compressed air control device of the winding unit of the present application is intended to realize the adjustment of the compressed gas amount supplied to the winding unit, so that the compressed gas supply amount can meet the normal operation of the equipment, avoid excessive compressed gas redundancy, reduce the use of compressed gas, prevent resource waste, and benefit energy conservation and emission reduction.

[0024] The compressed air control device of the rolling unit includes a flow regulating valve 11, a controller 12, an analog module 13 and a human-computer interaction module 14. The flow regulating valve 11 is used to be set on the compressed gas supply pipeline. The compressor and other gas source equipment supply compressed gas to the relevant equipment components of the rolling unit through the compressed gas supply pipeline. The flow regulating valve 11 can adjust the flow of compressed gas in the compressed gas supply pipeline. The flow regulating valve 11 can realize the opening and closing of the compressed gas supply pipeline. The flow regulating valve 11 can also realize the adjustment of the flow size of the compressed gas in the compressed gas supply pipeline. The analog module 13 and the controller 12 are electrically connected. The analog module 13 is electrically connected to the flow regulating valve 11, and the controller 12 adjusts the flow regulating valve 11 through the analog module 13. The analog module 13 can realize quantitative adjustment of the flow regulating valve 11, that is, it can realize the stepless flow adjustment of the flow regulating valve 11, and then realize the size adjustment of the compressed gas flow in the compressed gas supply pipeline. In this way, according to the working conditions of the relevant equipment components of the rolling unit, the corresponding flow regulating valve 11 is quantitatively adjusted so that the compressed gas supply meets the requirements of the relevant equipment components, avoiding excessive compressed gas supply redundancy, saving compressed gas consumption, and benefiting energy conservation and emission reduction.

[0025] The human-machine interaction module 14 is electrically connected to the controller 12 . The human-machine interaction module 14 can transmit a preset signal to the controller 12 , and the controller 12 performs specific control of the flow control valve 11 according to the preset signal.

[0026] In this embodiment, the operator inputs a preset signal from the human-computer interaction module 14, and the preset signal is transmitted from the human-computer interaction module 14 to the controller 12. After the controller 12 receives the preset signal transmitted by the human-computer interaction module 14, it controls the flow regulating valve 11 accordingly through the analog module 13 according to the preset signal to adjust the flow of compressed gas flowing through the flow regulating valve 11, thereby realizing the adjustment of the compressed gas flow in the compressed gas supply pipeline, so that the supply amount of compressed gas meets the working conditions requirements of the relevant equipment components in the rolling unit, and avoids excessive redundant compressed gas supply.

[0027] In this embodiment, the analog module 13 and the controller 12 are electrically connected by signals, the analog module 13 and the flow control valve 11 are electrically connected by signals, and the human-computer interaction module 14 and the controller 12 are electrically connected by signals. A preset signal can be input into the human-computer interaction module 14, and the preset signal represents a gain effect adjustment or a loss effect adjustment of the compressed gas flow in the compressed gas supply pipeline. The controller 12 receives the preset signal sent by the human-computer interaction module 14, and the controller 12 judges the preset signal and transmits a flow gain or flow loss signal to the analog module 13 according to the judgment result; the analog module 13 controls the flow control valve 11 according to the flow gain or flow loss signal at the controller to adjust the flow of compressed gas flowing through the flow control valve 11.

[0028] Preferably, a first signal input terminal 121 is provided on the controller 12, and the controller 12 is used to receive a signal of equipment shutdown through the first signal input terminal 121. The equipment referred to here refers to an equipment that is supplied with compressed gas by the compressed gas supply pipeline where the flow control valve 11 is located. When the controller 12 receives the equipment shutdown signal, the control device enters the shutdown mode. In the shutdown mode, the controller 12 controls the flow control valve 11 through the analog module 13, so that the flow control valve 11 is in a closed state, and the compressed gas supply pipeline is cut off and closed. In this way, when the equipment stops production, the compressed gas supply pipeline can be closed to prevent compressed gas leakage, thereby further avoiding waste of compressed gas.

[0029] In this embodiment, a second signal input terminal 122 is further provided on the controller 12. The controller 12 is used to receive a power-on signal of the device through the second signal input terminal 122, that is, to receive a signal that the device is powered on. When the controller 12 receives a power-on signal of the device, the control device releases the shutdown mode. After the shutdown mode is released, the controller 12 controls the flow regulating valve 11 through the analog module 13, so that the flow regulating valve 11 is in an open state, so that the compressed gas supply pipeline is opened, and the gas path begins to circulate, so as to adapt to the early warm-up of the equipment.

[0030] In this embodiment, a third signal input terminal 123 is also provided on the controller 12. The controller 12 is used to receive the device operation signal through the third signal input terminal 123. When the controller 12 receives the device operation signal, the controller 12 controls the flow control valve 11 through the analog module 13 to adjust the flow of compressed gas flowing through the flow control valve 11. In this embodiment, when the controller 12 simultaneously receives the preset signal and the device operation signal from the human-computer interaction module 14, the opening degree of the flow control valve 11 is adjusted to adjust the compressed gas supply flow rate.

[0031] In more detail, the equipment shutdown signal corresponds to the shutdown of the equipment and the stop of production. The equipment power-on signal corresponds to the start of powering on the equipment. This state is the transition between the equipment shutdown state and the equipment normal operating state. The equipment operation signal corresponds to the normal production of the equipment. Therefore, when the equipment is shut down, the flow regulating valve 11 closes the compressed gas supply pipeline and stops the supply of compressed gas to avoid wasting compressed gas. After the equipment starts to power on and before the equipment enters the normal production operation state, the flow regulating valve 11 opens so that the compressed gas supply pipeline starts to supply compressed gas. At this time, the opening of the flow regulating valve 11 can be the maximum. During this transition process, it is ensured that the equipment smoothly enters the normal production state. After the equipment is operating normally, the flow regulating valve 11 is adjusted so that the supply of compressed gas meets the production demand to avoid excessive redundancy of compressed gas. At this time, compared with the compressed gas demand under the standard operating conditions of the equipment, the redundancy of compressed gas supply is 3%-5%, to avoid wasting compressed gas.

[0032] In this embodiment, the first signal input terminal 121 and the third signal input terminal 123 can be connected to the electrical signal of the power source such as the motor of the equipment to realize the transmission of the equipment shutdown or equipment operation signal, and the second signal input terminal 122 can be connected to the electrical signal of the power terminal in the power supply box of the equipment to realize the transmission of the power signal on the equipment.

[0033] Preferably, the human-computer interaction module 14 includes an HMI touch screen, and the HMI touch screen is electrically connected to the controller 12. In this embodiment, the HMI touch screen and the controller 12 can be connected by wired transmission or wireless transmission. A flow control interface is provided on the touch screen to realize the adjustment of the flow control valve 11. Preferably, multiple compressed gas supply pipelines can be provided in the rolling machine group to supply compressed gas to multiple equipment components respectively, and multiple flow control valves 11 are also provided. A flow control valve 11 is provided on each compressed gas supply pipeline. Each flow control valve 11 is electrically connected to the analog module 13. The analog module 13 can adjust each flow control valve 11 separately. The touch screen has options for each flow control valve 11. After selecting the corresponding flow control valve 11, the flow of the flow control valve 11 can be adjusted and set.

[0034] Preferably, the flow regulating valve 11 is a proportional flow valve, which makes flow regulation more accurate.

[0035] The analog module 13 may be a separate module and electrically connected to the controller 12 via a cable. Preferably, the analog module 13 is provided on the controller 12. The analog module 13 is integrated into the controller 12, and the components are more compact. The controller 12 is preferably a PLC controller.

[0036] The control device also includes a power supply 15, the controller 12 is connected to the power supply 15, the analog module 13 is connected to the power supply 15, and the flow control valve 11 is connected to the power supply 15, so that the power supply 15 supplies power to the controller 12, the analog module 13 and the flow control valve 11. Preferably, the power supply 15 includes a 24V voltage line and a 0V voltage line, the controller 12 is respectively connected to the 24V voltage line and the 0V voltage line to power the controller 12, the analog module 13 is respectively connected to the 24V voltage line and the 0V voltage line to power the analog module 13, and the flow control valve 11 is respectively connected to the 24V voltage line and the 0V voltage line to power the flow control valve 11.

[0037] Preferably, the control device also includes a signal light 16, which is connected to the controller 12 and the power supply 15 respectively. The signal light 16 is used to indicate whether the flow regulating valve 11 is in a powered state. When the flow regulating valve 11 is in a powered state, the signal light 16 lights up, and when the flow regulating valve 11 is in a power-off state, the signal light 16 goes out to monitor whether the flow regulating valve 11 is powered normally.
