[0015] Smoke and Dust Filtration Control System

[0016] This application provides a dust filtration control system that, while ensuring filtration efficiency, can meet the needs of switching between desktop printing equipment and large centralized printing equipment at any time. It has a wide range of applications, is easy to combine, and is simple and quick to use, and has broad application prospects in various card laser etching equipment.

[0017] Figure 1 This is a schematic diagram of a smoke and dust filtration control system according to an embodiment of this application.

[0018] In some embodiments, the printing device can be a laser printer, the print head 1 can be a laser print head, the printed material 2 can be A4 paper or a card, etc., and the fume extraction tube 3 is placed below the print head 1 so that the fume extraction tube 3 can draw in the smoke and dust generated by the printing device during the printing of the printed material 2, such as... Figure 1 As shown.

[0019] The air intake device of the dust filtration system may include a nozzle control valve 4, a smoke extraction tube 3, and a nozzle detection sensor 5. The nozzle control valve 4 has at least one slot. The first end of the smoke extraction tube 3 is located below the printhead 1, and the second end of the smoke extraction tube 3 is connected to the nozzle control valve 4 through the slot. The nozzle control valve 4 is connected to the nozzle detection sensor 5 so that the sensor 4 can detect the connection information of the smoke extraction tube on the nozzle control valve 4. The host computer 6 can monitor this connection information. If the connection information indicates that the number of smoke extraction tubes 3 successfully connected to the nozzle control valve 4 meets a preset threshold, the host computer 6 controls the turbine fan 9 to rotate, pushing the dust from the smoke extraction tube 3 through the exhaust pipe to the filter box 11, so that the filter box 11 filters the dust generated during the printing process.

[0020] As an example, for desktop laser etching equipment, usually only one smoke tube 3 is needed to meet daily printing work. Therefore, the preset threshold corresponding to the number of smoke tubes 3 can be set to 1. The host computer can monitor the connection information between the nozzle control valve 4 and the smoke tube 3 detected by the nozzle detection sensor. If the host computer monitors the connection information indicating that one smoke tube 3 is successfully connected to the nozzle detection sensor 4, the host computer 6 controls the turbine fan 9 to rotate.

[0021] For large-scale centralized laser etching equipment, multiple suction tubes 3 are usually required to meet daily printing needs. If the preset threshold corresponding to the number of suction tubes 3 is set to 6, the host computer can monitor the connection information between the suction control valve 4 and the suction tubes 3 detected by the suction detection sensor. If the host computer monitors the connection information indicating that 6 suction tubes 3 are successfully connected to the suction detection sensor 4, the host computer 6 controls the turbine fan 9 to rotate.

[0022] In one possible implementation, such as Figure 1 As shown, the smoke outlet pipe includes a first smoke pipe 8 and a second smoke pipe 10. The first end of the first smoke pipe 8 is connected to the air outlet of the suction nozzle control valve 4, and the second end of the first smoke pipe 8 is connected to the air inlet of the turbofan 9. The first end of the second smoke pipe 10 is connected to the air outlet of the turbofan 9, and the second end of the second smoke pipe 10 is connected to the filter box 11. Through the directional connection of the first smoke pipe 8 and the second smoke pipe 10, and driven by the airflow generated by the rotation of the turbofan 9, the smoke is accelerated by the turbofan 9 before entering the filter box 11, which improves the efficiency of effectively guiding the smoke into the filter box 11 and enhances the filtration efficiency. At the same time, it ensures that the entire process of smoke generation and filtration takes place in a closed pipe, preventing the spread of smoke in the working environment.

[0023] In one possible implementation, the turbofan Hall controller 12 can be used to control the rotational parameters of the turbofan 9. For example... Figure 1 As shown, the turbofan Hall controller 12 is connected to the host computer 6 via the RJ45 interface of the communication control board 7. After determining the speed parameters of the turbofan, the host computer 6 can send control commands to the communication control board 7 through the RJ45 interface. The communication control board 7 then sends these control commands to the turbofan Hall controller 12. The turbofan Hall controller 12 determines the speed parameters of the turbofan 9 based on these control commands, causing the turbofan 9 to rotate according to these speed parameters. The control command corresponding to the speed parameters of the turbofan 9 determined by the host computer 6 can be based on the product of the number of smoke tubes 3 and the preset speed of the turbofan 9. Here, the preset speed can be determined according to the different printing materials. Through the host computer 6 and the turbofan Hall controller 12, the operator can remotely control the speed of the turbofan 9 from a location far from the printing area, improving operational flexibility. The host computer 6 can automatically calculate the required speed parameters of the turbofan 9 based on the number of smoke extraction tubes 3, and issue control commands through the communication control board 7 to achieve automated control of smoke filtration during the printing process, reducing manual intervention. At the same time, since the number of smoke extraction tubes 3 is adjustable, the speed of the turbofan 9 will be adjusted according to the preset speed and the number of smoke extraction tubes 3, thus adapting to the smoke filtration tasks of different printing equipment and improving the user experience.

[0024] As an example, if the printed document 2 is a card, experiments can determine that when a smoke extraction pipe 3 is connected to the printing device, the corresponding exhaust volume during the smoke extraction process is 100 CPM. If the speed of the turbofan 9 in the printing device is 6000 RPM, which can meet the smoke filtration requirements during the printing process, then the preset speed of the turbofan 9 can be set to 6000 RPM. If the threshold for the number of smoke extraction pipes 3 set during the printing process is 6, then after the host computer 6 monitors that the number of smoke extraction pipes 3 successfully connected to the nozzle control valve 4 meets the requirement of 6, the host computer 6 determines the speed parameter of the turbofan to be 6*6000=36000 RPM, and sends a control command to the turbofan 9 through the communication control board 7, instructing the turbofan to rotate at a speed of 36000 RPM.

[0025] like Figure 1 As shown, the connection between the filter box and the smoke outlet pipe is a threaded structure. The filter box is connected to the second end of the second smoke outlet pipe through the threaded structure, which allows for easy disassembly and replacement of the external filter box.

[0026] like Figure 1 As shown, the speed display screen 13 is connected to the turbofan via the turbofan Hall controller 12, enabling real-time monitoring of the turbofan's speed and providing a visual display of the current speed. This visual display allows the operator to intuitively see the turbofan's speed, quickly determine if the turbofan is operating within the normal range, and simplify the fault diagnosis process. Even in the event of a fault, such as excessively high or low speeds, appropriate measures can be taken to prevent potential equipment damage or safety accidents.

[0027] like Figure 1 As shown, the manual speed adjustment button 14 is used to manually adjust the speed parameters of the turbofan. By setting the manual speed adjustment button 14, a method for immediate speed adjustment can be provided in case the automatic control system malfunctions or becomes unsuitable, ensuring the system can continue to operate effectively.

[0028] Based on experimental testing, this application shows that each filter cartridge with a diameter of 8cm and a thickness of 3cm can be used for 3 years with a single smoke extraction tube. The lifespan decreases by six months with each additional smoke extraction tube. Therefore, before using the dust filtration system, the lifespan of the filter cartridge can be determined. If the lifespan meets the preset usage time, the printing equipment can be filtered using the dust filtration system. If the lifespan does not meet the preset usage time, the filter cartridge should be replaced before filtering the printing equipment again using the dust filtration system. The preset usage time can be determined based on actual printing needs.

[0029] The dust filtration system proposed in this application allows for automatic adjustment of the turbine fan speed based on the number of smoke extraction tubes when switching between different types of printing equipment. This automatically adjusts the airflow for dust filtration, ensuring efficient dust filtration. It meets the dust filtration needs of both desktop and large-scale centralized printing equipment. The smoke extraction tubes and filter boxes are also easy to install, have a wide range of applications, are easy to assemble, and are simple and quick to use. It has broad application prospects in various card laser etching equipment.

[0030] Smoke and dust filtration control methods

[0031] This application provides a method for controlling smoke and dust filtration. This method can ensure the filtration effect while meeting the needs of switching between desktop printing equipment and large centralized printing equipment at any time. It is simple, fast, efficient and has broad application prospects.

[0032] Figure 2 This is a flowchart of a smoke and dust filtration control method according to an embodiment of this application. The smoke and dust filtration control method of this application can be applied to a smoke and dust filtration system. Figure 2 As shown, the smoke and dust filtration control method in this embodiment includes the following steps:

[0033] Step 201: Monitor the connection information of the smoking tube on the mouthpiece control valve.

[0034] In some embodiments, the dust filtration system may be as follows Figure 1 As shown, the connection information of the suction tube 3 on the suction control valve 4 detected by the suction tube detection sensor 5 can be monitored by the host computer 6. This connection information includes the number of successfully connected suction tubes 3 on the suction control valve 4.

[0035] Step 202: If the number of smoke tubes successfully connected to the nozzle control valve meets the preset threshold, control the turbine fan to rotate so that the smoke generated during printing can be pushed from the smoke tube through the smoke outlet tube to the filter box, so that the filter box can filter the smoke.

[0036] In some embodiments, if the host computer 6 detects that the smoke tube 3 successfully connected to the nozzle control valve 4 meets a preset threshold, the rotation parameters of the turbofan are determined based on the number of smoke tubes 3. These rotation parameters can be the product of the number of successfully connected smoke tubes 3 and a preset rotation value.

[0037] After obtaining the rotation parameters, the host computer 6 can send a control command including the rotation parameters to the turbofan, thereby controlling the turbofan to rotate based on the rotation parameters, so as to drive the smoke generated by the printing equipment during the printing process from the smoke extraction pipe through the smoke outlet pipe to the filter box, so that the filter box can filter the smoke.

[0038] The dust filtration method proposed in this application is applicable to both desktop printing equipment and large centralized printing equipment. When switching between different types of printing equipment, simply adjusting the preset threshold corresponding to the successfully connected suction tube on the suction nozzle control valve can automatically adjust the speed of the turbine fan, thereby automatically adjusting the dust filtration airflow and achieving efficient dust filtration. It has broad application prospects in various card laser etching equipment.
