Technical Field
[0001] This utility model relates to the field of wood processing technology, and in particular to a device for quantitative impregnation of flame retardants for engineered wood products. Background Technology
[0002] As an important industrial material, engineered wood products are widely used in furniture manufacturing and building decoration. With the increasing awareness of fire safety, the flame retardant performance of engineered wood products has become a key indicator. The flame retardant quantitative impregnation device is the core equipment to ensure the flame retardant effect of engineered wood products. It imparts fire resistance to the board by uniformly penetrating the flame retardant into the interior of the engineered wood product. The performance of the device directly affects the quality and efficiency of the flame retardant treatment of engineered wood products.
[0003] Early flame retardant metering impregnation devices mostly consisted of simple impregnation tanks, conveyor rollers, and manual metering systems. Operators relied on experience to control the impregnation time and flame retardant dosage. This method was not only inefficient but also resulted in uneven impregnation areas, with significant differences in flame retardant penetration between the edges and corners of the engineered wood panels and the center area, leading to inconsistent overall flame retardant performance. To address these issues, existing devices employ automated conveying mechanisms and metering pumps. Motor-driven conveyor rollers uniformly transport the panels, while the metering pump precisely controls the flame retardant flow rate, improving the impregnation effect to some extent. However, existing devices still... There are obvious shortcomings. Because existing devices mostly use a single-plane impregnation method, the engineered wood panels are only immersed horizontally in the impregnation tank. The impregnation process is completed by direct contact with the flame retardant solution, avoiding the randomness caused by manual operation. However, due to the gap between the conveyor roller and the board, and the lack of dynamic adjustment of the solution flow in the impregnation tank, the surface of the board and the contact area with the roller cannot be fully wetted. At the same time, there is a large difference in the penetration depth of the flame retardant between the upper and lower surfaces and the center of the board. This makes it difficult to achieve a uniform standard for the flame retardant performance of different areas of the engineered wood panels, affecting product quality and market competitiveness.

[0019] Reference Figure 1 , Figure 2 and Figure 6The temperature control component 3 includes a motor 307. The right end of the motor 307 is fixedly connected to the right side of the inner wall of the chassis 5. The motor 307 provides power to drive the rotating rod 306 to rotate, providing a power source for the operation of the entire temperature control component 3. The left end of the motor 307 is fixedly connected to the rotating rod 306. The rotating rod 306 transmits the power of the motor 307 and carries the second magnet 305 and the monitoring component 308, realizing the functions of power transmission and component support. The second magnet 305 is fixedly connected to the front side of the outer wall of the rotating rod 306. The second magnet 305 attracts the first magnet 304 to form a circuit to control the operation of the motor 307. In the transition state; magnet 304 is slidably connected to the left side of magnet 2 305. Magnet 304 controls the circuit's on / off state by engaging or disengaging with magnet 2 305, thereby controlling the working state of motor 307; displacement block 301 is fixedly connected to the left side of magnet 1 304. Displacement block 301 is used to transmit the displacement of force block 302 and conduct temperature changes to magnet 1 304, realizing the transmission of force and temperature signals; force block 302 is fixedly connected to the front side of displacement block 301. Force block 302 is used to receive external force and push displacement block 301 to move, triggering the circuit connection; the rear side of displacement block 301 is fixedly connected to... A second spring 303 is connected to the device. The second spring 303 provides a restoring force to reset the first magnet 304 after it loses its magnetism, ensuring the temperature control component 3 can operate repeatedly. A monitoring component 308 is installed on the top of the outer wall of the rotating rod 306. The monitoring component 308 monitors the device temperature in real time and triggers an alarm to ensure safe operation of the device. The monitoring component 308 includes an analyzer 3081. The bottom end of the analyzer 3081 is fixedly connected to the top of the outer wall of the rotating rod 306. The analyzer 3081 receives temperature data transmitted by the thermometer 3083, analyzes and processes it, and determines whether the device temperature is abnormal. Transmission tubes 3082 are fixedly connected to the front right side of the analyzer 3081. Transmission tubes 3082 are used to transmit temperature data and alarm signals, realizing the transmission of temperature signals and alarm commands. A thermometer 3083 is fixedly connected to the front side of the transmission tube 3082. The thermometer 3083 is used to monitor the internal temperature of the device in real time and transmit the temperature data to the analyzer 3081, providing a data source for temperature monitoring. An alarm 3084 is fixedly connected to the rear side of the transmission tube 3082. The alarm 3084 is used to issue an alarm to remind the operator when the analyzer 3081 determines that the temperature is abnormal, so that timely measures can be taken to avoid danger. Specifically, the temperature control component 3 achieves the device temperature monitoring and regulation functions through the coordinated operation of various components. The motor 307 provides power to drive the rotating rod 306 to rotate, and the rotating rod 306 drives the second magnet 305 to rotate synchronously, providing a structural basis for the circuit opening and closing. The force block 302 is pushed by the external force to push the displacement block 301, so that the first magnet 304 and the second magnet 305 are attracted to form a circuit, and the motor 307 continues to run. When the device temperature rises, the displacement block 301 conducts heat to the first magnet 304, causing it to lose its magnetism and separate from the second magnet 305, the circuit is broken, the motor 307 stops working, and the second spring 303 resets the first magnet 304. At the same time, the thermometer 3083 monitors the internal temperature of the device in real time and transmits the data to the analyzer 3081 through the transmission tube 3082. The analyzer 3081 analyzes and judges whether the temperature is abnormal. If it is abnormal, it triggers the alarm 3084 to issue an alarm through the transmission tube 3082.
[0020] Reference Figure 1 and Figure 2 The bottom of the thermometer 3083 is fixedly connected to the top rear side of the chassis 5. The thermometer 3083 is used to monitor the temperature data during the operation of the device in real time and provide temperature information to the temperature control component 3. The bottom of the alarm 3084 is fixedly connected to the top front side of the chassis 5. The alarm 3084 is used to sound an alarm when an abnormal signal is received, reminding the operator to deal with the abnormal operation of the device in time. The bottoms of the two fixing blocks 202 are fixedly connected to the top left and right sides of the balance plate 207, respectively. The balance plate 207 is used to maintain the balance and stability of the immersion mechanism 2 during operation through the connection with the fixing blocks 202. The bottoms of the two containers 206 on adjacent sides are fixedly connected to the front and rear sides of the balance plate 207. The balance plate 207 provides installation support points for the containers 206 and further enhances the overall stability of the device. Two wheels 6 are fixedly connected to the bottom left and right sides of the electrical cabinet 4. The wheels 6 are used to realize the movement function of the electrical cabinet 4 and the entire device, which facilitates the position adjustment and transportation of the equipment. A screen 7 is fixedly connected to the left side of the outer wall of the chassis 5. The screen 7 is used to display the operating parameters of the device. Specifically, the temperature gauge 3083 is fixed to the rear top of the chassis 5 to monitor the operating temperature of the device in real time. It transmits the collected data to the analyzer 3081 in the temperature control assembly 3 as the basis for temperature judgment. When the analyzer 3081 determines that the device temperature is abnormal based on the temperature data, it sends a signal to the alarm 3084 fixed to the front top of the chassis 5 via the transmission pipe 3082. The alarm 3084 immediately sounds an alarm to remind the operator to take action and prevent safety issues caused by excessive temperature. The balance plate 207, connected to the bottom of the two fixed blocks 202, provides stable support for the impregnation mechanism 2, ensuring that the rotating shaft 201 and the impregnation plate 204 remain balanced during operation and preventing uneven impregnation due to center of gravity shift. Meanwhile, the bottom of the two containers 206 on adjacent sides is fixed to the front and rear sides of the balance plate 207. The balance plate 207 provides a stable installation base for the containers 206, ensuring the stable storage of the flame retardant liquid and further enhancing the overall structural stability of the device. The wheels 6 on the left and right sides of the bottom of the electrical cabinet 4 allow the electrical cabinet 4 and the entire device to move flexibly, facilitating the adjustment and transportation of the equipment in the production site to meet different production layout requirements. The screen 7 on the left side of the outer wall of the chassis 5 is connected to the various control components of the device, displaying in real time the temperature data monitored by the temperature instrument 3083, the key parameters of the operating status of the temperature control component 3, and the working parameters of the impregnation mechanism 2. The operator can intuitively obtain the device operating information through the screen 7, and promptly grasp the operating status of the equipment and make adjustments.
[0021] Working principle: The engineered wood to be impregnated is placed in the impregnation plate 204, which provides a stable load-bearing space for the board. The hydraulic column 2081 is activated, driving the top plate 2084 to move downwards and precisely cover the top of L-shaped block 1 203. L-shaped block 2085 is tightly engaged with L-shaped block 1 203 to form a sealed structure. The valve 2089 is opened to quickly remove air from the device and create a vacuum environment. To prevent outside air from re-infiltrating, foam adhesive 2086 further enhances the sealing effect. Under the action of vacuum negative pressure, the flame retardant liquid in container 206 is quickly drawn in and impregnated. The impregnation plate 204 ensures that the flame retardant liquid can fully fill the impregnation space. The impregnation block 205 efficiently absorbs the flame retardant liquid and evenly applies it to the surface of the wood board. To ensure that the wood board is fixed in position during the impregnation process and to avoid uneven impregnation due to movement, the buffer plate 2094 plays a limiting function, accurately positioning the wood board in the predetermined position. The spring 2092 provides a buffer force for the wood board through elastic deformation, ensuring that the wood board remains stable during the impregnation process. The rotating shaft 201 can drive the impregnation plate 204 and the wood board inside to rotate during the impregnation operation. Furthermore, when the device operates continuously for a long time and the temperature gradually rises, the displacement block 301, as a key carrier for temperature sensing, can conduct heat to magnet 304. When the temperature of magnet 304 reaches its Curie point, the magnetism of magnet 304 will quickly disappear. As the temperature continues to rise to the danger threshold, magnet 304 loses its magnetism, and the attraction between it and magnet 305 disappears. The originally connected circuit is instantly disconnected. After the circuit is disconnected, motor 307 stops running due to power failure, and the overall operation of the device enters a paused state. The pre-set spring 303 plays a reset role, quickly pulling the demagnetized magnet 304 back to its initial position, avoiding abnormal device startup due to misoperation or accidental re-attraction of magnet 304 after the temperature drops.
