[0026] In one embodiment of the present application, as shown in Figs. 1-2 The present application provides a kind of atomization wet water mechanism for paper production, including nozzle 1, data acquisition module 2 and PLC control system;Nozzle 1 includes spray head main body 10 and atomizing head 20, spray head main body 10 specifically has liquid inlet and liquid outlet, liquid inlet is used to receive water from water supply system, and liquid outlet is used to output liquid to atomizing head 20.Atomizing head 20 is connected with spray head main body 10, and is set at liquid outlet, atomizing head 20 is installed at liquid outlet, can convert water flow into small water mist particles, to realize uniform spraying water mist;Data acquisition module 2 includes flow sensor and pressure sensor;Flow sensor and pressure sensor are all set in atomizing head 20, and flow sensor and pressure sensor are all electrically connected with PLC control system.Among them, flow sensor is used to monitor the flow rate of water or wetting agent, to ensure the consistency of atomization effect.Pressure sensor is used to detect the pressure in the system, to ensure that atomization effect is not affected by pressure fluctuation.PLC (control system as the core of control system, receives sensor signal and executes preset control strategy.

[0027] When working, the principle is as follows: when water supply system starts working, water flow enters spray head main body 10 through liquid inlet, and then flows to atomizing head 20.Atomizing head 20 disperses water flow into small water mist particles, which are sprayed out through the nozzle of atomizing head 20, and are uniformly sprayed on paper.Flow sensor and pressure sensor monitor the key parameters in atomization process in real time, and transmit data to PLC control system.PLC automatically adjusts the working state of nozzle 1, such as water quantity and pressure, according to these data and preset program, to ensure that paper obtains uniform humidity.

[0028] The atomizing wet water mechanism collects real-time data through flow sensors and pressure sensors, and the PLC control system can accurately control the water spray amount and pressure of the nozzle 1, ensuring the uniformity and stability of the water mist, thereby improving the quality of the tissue paper. It can realize precise control of the spraying process, thereby improving the uniformity of the moisture of the tissue paper, improving production efficiency and product quality. The PLC control system automatically adjusts the working state of the nozzle 1 according to the data feedback by the sensor to adapt to different production needs, reduce manual intervention, and improve production efficiency. The atomizing wet water mechanism can efficiently convert water into fine mist, reduce water waste, and reduce energy consumption, in line with the green and environmentally friendly production concept.

[0029] Further, the nozzle 1 is made of corrosion-resistant, wear-resistant, and non-stick materials such as stainless steel, ceramic, or special coating materials to reduce clogging and prolong the service life of the nozzle 1. The nozzle 1 is designed with a smoother internal channel to reduce dead angles and rough surfaces to reduce the possibility of material deposition.

[0030] In the present example, the atomizing head 20 includes a first nozzle portion 21 and a second nozzle portion 22, the first nozzle portion 21 is provided with a first channel 211, and the second nozzle portion 22 is provided with a second channel 221, the maximum pipe diameter of the first channel 211 is smaller than the minimum pipe diameter of the second channel 221; the second nozzle portion 22 is connected with the nozzle body 10, and the second channel 221 is in communication with the inside of the nozzle body 10, which allows the liquid to flow from the nozzle body 10 to the second nozzle portion 22; the first nozzle portion 21 is connected with the second nozzle portion 22, and the second channel 221 is in communication with the first channel 211. Specifically, the first nozzle portion 21 is arranged inside the second nozzle portion 22, and the liquid in the nozzle body 10 enters the first channel 211 through the second channel 221, and then is sprayed out through the nozzle of the first nozzle portion 21 to form a water mist. The first nozzle portion 21 and the second nozzle portion 22 are connected with each other, and this layout allows the liquid to flow between the two nozzle portions. The maximum pipe diameter of the first channel 211 is smaller than the minimum pipe diameter of the second channel 221, forming a pressure difference, and the first channel 211 is used for fine spraying due to its small pipe diameter

[0031] In this example, the first nozzle part 21 is provided with a first threaded connection part 212, and the second nozzle part 22 is provided with a first thread inside. The first threaded connection part 212 is threadedly connected with the first thread. Specifically, the first threaded connection part 212 is threadedly connected with the first thread, and this connection allows the two nozzle parts to be fixed and positioned in the axial direction. The threaded connection provides a reliable mechanical connection that can withstand certain tension and pressure, ensuring the stability of the nozzle during operation. The first nozzle part 21 and the second nozzle part 22 are connected to each other through the first threaded connection part 212 and the first thread, and their positional relationship is tightly connected to ensure that the liquid can flow smoothly from one nozzle part to another. Through the rotating action, the threads gradually engage until the two nozzle parts are tightly connected together, forming a sealed passage that allows the liquid to pass through. This threaded connection can also provide a certain degree of adjustment function, and the position and angle of the nozzle can be fine-tuned by rotating to adapt to different spraying needs. The nozzle 1 is designed for easy disassembly and cleaning, and can be quickly replaced or cleaned without special tools.

[0032] In this example, the second nozzle part 22 is provided with a second threaded part 222, and the second threaded part 222 is threadedly connected with the second thread provided on the nozzle body 10. Specifically, the second threaded part 222 is threadedly connected with the second thread, and this connection allows the second nozzle part 22 and the nozzle body 10 to be fixed and positioned in the axial direction. The threaded connection provides a reliable mechanical connection that can withstand certain tension and pressure, ensuring the stability of the nozzle during operation. The second nozzle part 22 and the nozzle body 10 are connected to each other through the second threaded part 222 and the second thread, and their positional relationship is tightly connected to ensure that the liquid can flow smoothly from the nozzle body 10 to the second nozzle part 22. When the second nozzle part 22 needs to be connected with the nozzle body 10, the second threaded part 222 of the second nozzle part 22 is screwed into the internal second thread of the nozzle body 10. Through the rotating action, the threads gradually engage until the second nozzle part 22 and the nozzle body 10 are tightly connected together, forming a sealed passage that allows the liquid to pass through. This threaded connection can also provide a certain degree of adjustment function, and the position and angle of the nozzle can be fine-tuned by rotating to adapt to different spraying needs. The nozzle 1 is designed for easy disassembly and cleaning, and can be quickly replaced or cleaned without special tools.

[0033] In this embodiment, a sealing part 30 is provided between the second nozzle part 22 and the nozzle body 10. Specifically, the sealing part 30 functions to prevent liquid from leaking at the connection between the second nozzle part 22 and the nozzle body 10, ensuring the accuracy and efficiency of the spraying. The sealing part 30 is located between the contact surface of the second nozzle part 22 and the nozzle body 10, or at the end of the threaded connection, to form a closed sealing area. The sealing ring is made of elastic materials such as rubber or silicone, which can fill the small gaps at the connection when compressed, thereby preventing liquid from leaking.

[0034] In this embodiment, a cooling water channel 223 is provided in the second nozzle part 22, which is not in communication with the second channel 221. Specifically, for high-temperature applications, the cooling water channel 223 is designed to prevent the nozzle 1 from being blocked due to heat accumulation and to prevent the nozzle 1 from overheating by circulating cooling water. The cooling water channel 223 provided in the second nozzle part 22 is a separate fluid channel for reducing the working temperature of the nozzle by cooling water. The second nozzle part 22 is provided with a water inlet 224 and a water outlet 225 in communication with the cooling water channel 223, so that the cooling water can flow in circulation. The cooling water channel 223 is not in communication with the second channel 221, which means that the cooling water and the spraying liquid are flowing separately, avoiding mixing. When the nozzle 1 is working, the spraying liquid flows through the second channel 221, and due to the heat generated during the spraying process, the temperature of the second nozzle part 22 may rise. The cooling water flows in circulation through the cooling water channel 223, absorbing the heat generated by the second nozzle part 22, thereby reducing the temperature of the nozzle. This temperature control helps to prevent the nozzle from being damaged due to overheating, while also helping to maintain the stability of the spraying liquid and the spraying accuracy.

[0035] In this embodiment, the nozzle 1 includes a micro-vibrator 40, which is provided inside the nozzle body 10 and electrically connected to the PLC control system. Specifically, by integrating the self-cleaning mechanism through the micro-vibrator 40, the self-cleaning function is realized. For example, by providing a micro-vibrator 40 (such as a vibration motor) inside the nozzle 1, the clogging is periodically removed.

[0036] In this embodiment, the nozzle 1 includes a filter screen 50, which is provided inside the nozzle body 10 and used for filtering impurities. Specifically, a 200-mesh stainless steel filter screen is provided in front of the nozzle body 10, effectively intercepting large-particle impurities.

[0037] In this embodiment, the data acquisition module 2 also includes a humidity sensor, which is provided on the production line for real-time monitoring of the humidity of the paper, and is electrically connected to the PLC control system. Specifically, the humidity sensor is installed on the production line to monitor the humidity of the paper in real time, ensuring that it meets the preset standards.

[0038] In the present example, the atomized wet water mechanism further comprises a servo motor, and the nozzle 1 is fixedly arranged on the output end of the servo motor. Specifically, the servo motor serves as an execution mechanism to control the movement or rotation of the nozzle 1 to adapt to production lines of different speeds and paper sheets of different sizes.

[0039] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and 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.
