Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0034] This application provides a processing system, including processing equipment and a fire extinguishing device, wherein the fire extinguishing device is connected to the processing equipment. Please see [link to relevant documentation]. Figure 1 and Figure 2 The processing equipment provided in this application includes a guide component 300, a processing platform 400, a 3D printing head 100, and an engraving laser 200. In some feasible embodiments, the processing equipment is a gantry structure (such as...). Figure 1As shown, the guide 300 is supported by two vertical columns along the Z-axis. The guide 300 can move up and down along the Z-axis, the 3D printing head 100 can move along the guide 300 in the Y-axis direction, and the processing platform 400 moves in the X-axis direction. Optionally, the processing equipment can be a CoreXY structure, where the guide 300 is supported by a frame on the processing equipment, the 3D printing head 100 can move along the guide in the XY plane under the drive of a belt, and the processing platform is connected to a Z-axis lead screw to achieve movement in the Z-axis direction. For example, the guide can be at least one of a Y-axis linear guide, a carbon rod, and an X-axis optical axis. Optionally, the processing equipment can also be a cantilever structure, where the guide 300 is supported by one Z-axis column, the guide 300 can move up and down along the Z-axis, the 3D printing head 100 can move along the guide 300 in the Y-axis direction, and the processing platform moves in the X-axis direction.

[0035] It should be understood Figure 1 This is merely an illustration and does not limit the structural type of the processing equipment. In this application, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. "Connection" includes detachable and non-detachable connections. For example, a fixed connection can include detachable fixed connections and non-detachable fixed connections, a rotating connection can include detachable rotating connections and non-detachable rotating connections, and a sliding connection can include detachable sliding connections and non-detachable sliding connections. A connection can also be a direct connection or an indirect connection through a component. For example, a detachable fixed connection refers to a connection where the positional relationship between at least two connected objects can be fixed in the installed state; similar examples include rotating connections and sliding connections.

[0036] For example, the 3D printing head 100 is slidably connected to the guide member 300. The guide member 300 supports the 3D printing head 100 and the engraving laser 200. The 3D printing head 100 is slidably connected to the guide member 300, and during processing, the 3D printing head 100 can slide linearly along the extension direction of the guide member 300. The guide member 300 can also drive the 3D printing head 100 to move along its width direction and move it up and down. The sliding of the 3D printing head 100 along the extension direction of the guide member 300, the movement of the 3D printing head 100 along its width direction, and the up and down movement of the 3D printing head 100 can be coordinated by a stepper motor and a transmission system. This allows the stepper motor to drive the 3D printing head 100 to move precisely in three-dimensional space via a lead screw, ensuring that the material processed by the 3D printing head 100 is shaped according to the designed trajectory.

[0037] Please see Figure 3 and Figure 4 The 3D printing head 100 and the engraving laser 200 are detachably connected. The 3D printing head 100 is provided with a mounting part 115, and the engraving laser 200 is provided with a connecting part 215. The 3D printing head 100 and the engraving laser 200 are connected by the cooperation of the mounting part 115 and the connecting part 215. There are various ways for the mounting part 115 and the connecting part 215 to cooperate. For example, the mounting part 115 and the connecting part 215 can cooperate by a snap-fit ​​part and a limiting groove. The limiting groove is provided in the mounting part 115, and the snap-fit ​​part is provided in the connecting part 215. The snap-fit ​​part extends into the limiting groove, so that the connecting part 215 clamps the mounting part 115, thereby connecting the 3D printing head 100 and the engraving laser 200. In this application, the connecting part 215 is provided with a corresponding protrusion as a snap-fit ​​part. When the engraving laser 200 is connected to the 3D printing head 100, the engraving laser 200 is installed on the 3D printing head 100 from top to bottom. The snap-fit ​​part on the connecting part 215 of the engraving laser 200 extends into the limiting groove provided on the mounting part 115 of the 3D printing head 100, and snaps the connecting part 215 of the engraving laser 200 onto the mounting part 115 of the 3D printing head 100, thereby connecting the engraving laser 200 and the 3D printing head 100. This facilitates the installation and disassembly between the 3D printing head 100 and the engraving laser 200, and improves the installation efficiency of the 3D printing head 100 and the engraving laser 200.

[0038] Please see Figure 5 and Figure 6The fire extinguishing device 500 provided in this application includes a containment bottle 510, an actuator 530 with an output shaft 531, and a trigger 540. The containment bottle 510 contains the extinguishing agent, which is a type of extinguishing agent used in mechanical equipment, such as dry powder or carbon dioxide extinguishing agent. A valve 512 is movably provided at the bottle opening 511 of the containment bottle 510, which controls the flow of the extinguishing agent. The valve 512 can be a one-way valve or a solenoid valve to ensure that the extinguishing agent does not leak in the non-triggered state and can open rapidly when triggered. The valve 512 can be opened by direct mechanical force or by electrical signal control. The actuator 530 can be an electric motor, pneumatic device, or hydraulic device, etc., used to convert input energy into mechanical energy and transmit it through the output shaft 531. The selection of the actuator 530 can be based on the specific application scenario and the characteristics of the extinguishing agent; for example, for applications requiring rapid response, a high-speed electric motor can be selected. One end of the trigger 540 is connected to the output shaft 531, and the other end of the trigger 540 is in active contact with the valve 512, ensuring that the valve 512 can be quickly opened when the actuator 530 is started. The trigger 540 can be a screw mechanism, lever mechanism, linkage mechanism, or gear mechanism, etc. For example, when the actuator 530 is an electric motor, the trigger 540 is a screw mechanism, and the valve 512 is a one-way valve, the screw mechanism is in active contact with the output shaft 531. When the output shaft 531 rotates, the screw mechanism moves linearly to contact the valve 512, causing the valve 512 to open. When using a fire extinguishing device, the speed of the motor is controlled to control the linear displacement of the screw mechanism, thereby controlling the opening degree of the valve 512. This makes the gas release process of the fire extinguishing device controllable. Controlling the opening of the valve 512 by the actuator 530 reduces manual operation and improves the automation level of the fire extinguishing device. The efficient drive of the actuator 530 and the rapid response of the trigger 540 enable the extinguishing agent to be released in a short time, improving the efficiency and effectiveness of fire suppression.

[0039] The nozzle 511 of the containment bottle is connected to the processing equipment. Under normal conditions, the extinguishing agent inside the containment bottle 510 is sealed by valve 512 and cannot flow out. When a fire is detected inside the processing equipment, the actuator 530 receives a start signal, and the output shaft 531 begins to rotate or move, driving the trigger 540 to move. The movement of the trigger 540 pushes the valve 512 to open, and the extinguishing agent is rapidly released to the fire source through the pipe connecting the nozzle 511 and the processing equipment, thus extinguishing the fire. The efficient drive of the actuator 530 and the rapid response of the trigger 540 enable the extinguishing agent to be released in a short time, improving the efficiency and effectiveness of fire extinguishing.

[0040] Please see Figure 6The fire extinguishing device also includes a limiting member 541, through which a trigger member 540 is movably inserted, and the limiting member 541 and the trigger member 540 are threadedly engaged. The limiting member 541 has a cylindrical structure with an internal channel matching the trigger member 540. The trigger member 540 passes through this channel and performs linear and rotational movements within the limiting member 541. During rotational movement, the limiting member 541 restricts the rotation angle of the trigger member 540, preventing excessive rotation that could damage the device or cause false triggering. During linear movement, the limiting member 541 restricts the displacement distance and direction of the trigger member 540, ensuring that the trigger member 540 moves in a straight line to contact the valve 512. The limiting member 541 and the trigger member 540 are threadedly engaged, ensuring a tight connection and precise movement between them. For example, when the trigger member 540 is a lead screw, the limiting member 541 is a lead nut. The output shaft rotates to drive the lead screw to rotate. The lead screw and the output shaft are loosely fitted. The lead screw moves forward while rotating. Pressing the valve of the containment bottle 510 releases the extinguishing agent, which is then released into the processing equipment through the vent.

[0041] Please see Figure 7 and Figure 8 The trigger 540 is provided with a slide groove 542, and one end of the output shaft 531 extends into the slide groove 542 and slides in cooperation with the slide groove 542. The inner wall of the slide groove 542 has a first plane 543 and a first curved surface 544, which are connected. The outer wall of the output shaft 531 has a second plane 532 and a second curved surface 533, which are connected. The first plane 543 contacts the second plane 532, and the first curved surface 544 contacts the second curved surface 533.

[0042] The fire extinguishing device also includes a connector 520, which connects the containment bottle 510 and the actuator 530. One end of the connector 520 connects to the bottle neck 511 of the containment bottle 510, and the other end connects to the actuator 530. The connection between the connector 520 and the containment bottle 510 can be a threaded connection, a snap-fit ​​connection, or other suitable connection method to ensure a secure and airtight connection. The connection between the connector 520 and the actuator 530 can be a screw connection. The connection between the connector 520 and the containment bottle 510 and the actuator 530 is secure and reliable, ensuring the stability of the device in various operating environments. Please refer to [link to relevant documentation]. Figure 6 In some feasible embodiments, the bottle opening 511 extends into the connector 520, and the connector 520 is threadedly connected to the receiving bottle 510.

[0043] A first seal 550 is provided between the actuator 530 and the connector 520, and the first seal 550 is in close contact with both the actuator 530 and the connector 520. The first seal 550 is made of a material with excellent elasticity and corrosion resistance, such as silicone rubber, fluororubber, and nitrile rubber. These materials can maintain good sealing performance under various environmental conditions and have a long service life. The first seal 550 is designed in the shape of a standard sealing ring, such as an O-ring, V-ring, or U-ring. These shapes provide a good sealing contact surface and generate a self-tightening effect under pressure, further enhancing the sealing effect. For example, an O-ring will undergo radial deformation under pressure, thereby enhancing the sealing performance with the contact surface. The first seal 550 is installed using snap-fit, press-fit, or threaded fastening methods to ensure that it will not loosen or fall off during use. For example, snap-fit ​​installation can fix the seal in a predetermined position through a simple mechanical structure, while threaded fastening uses screws or nuts to press the seal onto the contact surface. When the fire extinguishing device is in operation, the pressure or tension generated by the actuator 530 acts on the connector 520, causing relative movement or deformation between the connector 520 and the actuator 530. At this time, the first seal 550 deforms under pressure, further enhancing the sealing performance with the contact surface. For an example, please refer to... Figure 6 The connector 520 is provided with a first sealing groove 551. During the installation process, the first sealing element 550 is pressed into the sealing groove to fix it between the driver 530 and the connector 520.

[0044] A second sealing element 560 is provided between the bottle neck 511 and the connector 520. The second sealing element 560 is in close contact with the connector 520 and with all parts of the bottle neck 511 except for the valve 512. The material of the second sealing element 560 is a material with excellent elasticity and corrosion resistance, such as silicone rubber, fluororubber, and nitrile rubber. These materials can maintain good sealing performance under various environmental conditions and have a long service life. The shape of the second sealing element 560 is designed as a standard sealing ring shape, such as an O-ring, V-ring, or U-ring. These shapes provide a good sealing contact surface and generate a self-tightening effect under pressure, further enhancing the sealing effect. For example, an O-ring will undergo radial deformation under pressure, thereby enhancing the sealing performance with the contact surface. The second sealing element 560 is installed using snap-fit, press-fit, or threaded fastening methods to ensure that it will not loosen or fall off during use. For example, snap-on installations use a simple mechanical structure to secure the seal in a predetermined position, while threaded fastenings use screws or nuts to press the seal against the contact surface. When the fire extinguishing device is in operation, the pressure or tension generated by the actuator 530 acts on the connector 520, causing relative movement or deformation between the connector 520 and the bottle neck 511. At this time, the second seal 560 deforms under pressure, further enhancing the sealing performance with the contact surface. For an example, please refer to [link to example]. Figure 6 The connector 520 is provided with a second sealing groove 561. During installation, the second seal 560 is placed in the second sealing groove 561 to fix it between the driver 530 and the connector 520. The design and installation method of the second seal 560 ensures that it can provide reliable sealing performance under various working conditions, prevent fire extinguishing agent leakage or the entry of external impurities, and improve the overall reliability of the fire extinguishing device.

[0045] The connector 520 is equipped with a position detector for detecting the position of the containment bottle 510. The position detector can employ various types of sensors, such as a mechanical limit switch that detects the position of the containment bottle 510 through physical contact; when the containment bottle 510 reaches a predetermined position, the limit switch is triggered, outputting a corresponding electrical signal. Alternatively, a photoelectric sensor can detect the position of the containment bottle 510 by utilizing the obstruction or reflection of a light beam. Or, a magnetic induction sensor can detect the position of the containment bottle 510 by utilizing changes in a magnetic field; a magnet is provided on the containment bottle 510, and when the magnet on the containment bottle 510 approaches or moves away from the sensor, the sensor outputs a corresponding electrical signal. The position detector can be installed on the top, side, or bottom of the connector 520. For example, the sensor is a microswitch, located between the connector 520 and the containment bottle 510. When the containment bottle 510 moves to a predetermined position, the microswitch is triggered, and the fire extinguishing device acquires the position signal and converts it into a standard electrical or digital signal for controlling the start, stop, or other operations of the fire extinguishing device. For example, when the containment bottle 510 reaches the correct position, the position detector outputs a high-level signal, triggering the actuator 530 to start. In some feasible embodiments, the processed signal is transmitted to the control unit or actuator via a connection line to control the fire extinguishing device. For example, the position detector can be connected to the control circuit of the fire extinguishing device. When the containment bottle 510 is detected to be in the correct position, the control circuit activates the actuator 530 to control the trigger 540 to open the valve 512 to release the extinguishing agent. The position detector can confirm in real time whether the containment bottle 510 is in the correct position. For example, when installing or replacing the containment bottle 510, the position detector can detect whether the containment bottle 510 is installed correctly, avoiding device failure or extinguishing agent leakage due to improper installation. The position detector can also provide safety protection for the fire extinguishing device. For example, when the containment bottle 510 is not in the correct position, the position detector can output a safety signal to prevent the actuator 530 from starting, preventing accidental release of the extinguishing agent. The signal from the position detector can be used to achieve automated control of the fire extinguishing device. For example, the signal from the position detector can trigger an alarm system, initiate the fire extinguishing process, or notify relevant personnel.

[0046] The connector 520 is fixedly connected to the limiting member 541, for example, by screws. The limiting member 541 is used to restrict the movement direction of the trigger member 540. The connector 520 has a cavity 521 and a vent 522 communicating with the cavity 521. The cavity 521 houses the trigger member 540 and the bottle opening 511 of the bottle 510. When fire extinguishing is required, the actuator 530 controls the output shaft 531 to move, thereby controlling the trigger member 540 to contact the valve 512. When the valve 512 opens, the extinguishing agent flows out from the valve 512, passes through the cavity 521 and the vent 522 communicating with the cavity 521, and is output to the outside of the connector 520. The vent 522 communicating with the outside of the cavity 521 balances the air pressure inside and outside the cavity 521, preventing sealing failure or device damage due to air pressure difference. Cavity 521 also provides space for the movement of trigger 540, protects the movement of trigger 540 during fire extinguishing operations, and ensures the safety of the fire extinguishing device.

[0047] In some feasible implementations, the vent is connected to a hose connector to facilitate gas exchange or pressure regulation with other equipment or systems. The hose connector can be a quick-connect coupling, a threaded coupling, or other standardized connection method. For example, a quick-connect coupling allows users to quickly connect or disconnect the hose without tools, while a threaded coupling provides a more secure connection. The hose connector is made of corrosion-resistant, high-temperature-resistant metals or high-performance plastics, such as stainless steel, brass, or polyamide, ensuring its durability and reliability under various environmental conditions. In some feasible implementations, when the extinguishing agent needs to be replenished or replaced periodically, the hose connector allows the fire extinguishing device to be connected to the gas supply system for rapid replenishment of the extinguishing agent. In high-pressure or low-pressure environments, the internal pressure of the fire extinguishing device needs to be balanced with the external environment. The hose connector allows the fire extinguishing device to be connected to a pressure regulating system for precise control of the internal pressure. Through gas exchange and pressure regulation functions, the internal pressure of the fire extinguishing device can be kept stable, preventing seal failure or device damage due to pressure differences, thus improving the reliability and service life of the device.

[0048] In some feasible implementations, the fire extinguishing device can be installed on the side of the processing equipment. The air pipe connector on the vent of the fire extinguishing device is connected to the inside of the processing equipment via an air pipe. Under normal conditions, the extinguishing agent in the containment bottle is sealed by a valve and cannot flow out. When a fire is detected inside the processing equipment, the actuator receives a start signal, and the output shaft begins to rotate or move, driving the trigger element to move. The movement of the trigger element pushes the valve open, and the extinguishing agent is rapidly released to the fire source through the cavity, vent, air pipe connector, and air pipe, thus extinguishing the fire. The efficient drive of the actuator and the rapid response of the trigger element enable the extinguishing agent to be released in a short time, improving the efficiency and effectiveness of fire extinguishing.
