Description
Technical Field
[0001] This invention relates to the field of wood particleboard testing technology, specifically to a device for testing finished wood particleboard products. Background Technology
[0002] Wood particleboard is a type of engineered wood product made from wood or wood fibers through a process of shavings preparation, drying, gluing, laying, and hot pressing. Due to its high raw material utilization rate, low cost, and stable structure, it is widely used in furniture manufacturing, interior decoration, and packaging materials. As a fundamental material in furniture manufacturing, interior decoration, and packaging, the physical and mechanical properties of wood particleboard directly determine the durability and suitability for various applications of the final product. Therefore, after production, the relevant properties of wood particleboard need to be tested to verify whether the product meets basic standards for usability and durability.
[0003] In the current technology, different equipment is required to test different properties of wood particleboard. It is impossible to integrate the testing of different properties of wood particleboard into a single testing device. This means that equipment needs to be changed frequently during the testing process, and the operation process is cumbersome. Furthermore, the test results of each property are independent of each other, which makes it difficult to conduct a comprehensive evaluation of the quality of the particleboard. Therefore, it cannot meet people's needs for rapid and comprehensive evaluation and testing of multiple properties of wood particleboard. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for detecting finished wood shavings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wood shavings finished product testing device includes a housing and two fixed plates. The two fixed plates are respectively installed on the top sides of the housing. Two electric push rods are installed on the top of each fixed plate. The telescopic ends of the two electric push rods are connected to a top plate. A testing mechanism is provided at the bottom of the top plate. A movable frame is provided between the two fixed plates. The movable frame is equipped with a driving mechanism for automatically moving the wood shavings to the bottom of the testing mechanism. The driving mechanism includes a movable seat that is slidably installed inside the movable frame. A clamping mechanism for clamping and fixing the wood shavings is provided on the top of the movable seat.
[0007] Optionally, the top of the box is provided with two cover plates, and two first sliding grooves are opened on the inner walls of both sides of the box. A first slider is installed inside the two first sliding grooves, and the outer walls of both cover plates are connected to the first sliders that are close to them.
[0008] Optionally, an electric heating element is installed at the bottom of the box, and a drain pipe is installed on one side of the outer wall of the box.
[0009] Optionally, a second sliding groove is provided on the outer wall of the two adjacent fixed plates, and a second slider is installed inside the two second sliding grooves. The movable frame is rotatably installed between the two second sliders.
[0010] Optionally, the inner walls on both sides of the movable frame are provided with first grooves, and lead screws are rotatably installed inside the two first grooves. The two ends of the movable seat are threadedly connected to the outer walls of the two lead screws.
[0011] Optionally, the clamping mechanism includes a second groove opened on the top of the movable seat, a double-ended screw is rotatably installed inside the second groove, and two fixing brackets are threadedly installed on the outer wall of the double-ended screw. The outer wall of the top of the two fixing brackets that are close to each other is connected to a mounting block through two first electric telescopic rods. The outer wall of the two mounting blocks that are close to each other is rotatably installed with a clamping block, and the outer wall of the two clamping blocks that are close to each other is installed with a limit block.
[0012] Optionally, each of the two fixing frames is equipped with two second electric telescopic rods. The telescopic ends of the two second electric telescopic rods are jointly equipped with a rectangular block. The two rectangular blocks are equipped with multiple third electric telescopic rods. The telescopic ends of the multiple third electric telescopic rods are equipped with a first probe for detecting the thickness of the particleboard.
[0013] Optionally, two sealing plates are rotatably mounted on the top of the rectangular block, and torsion springs are fitted on the rotating surfaces of both sealing plates.
[0014] Optionally, the detection mechanism includes a telescopic cylinder installed on the top of the top plate. The telescopic end of the telescopic cylinder passes through the top plate and is mounted on a fixed seat. A detection block is rotatably installed inside the fixed seat. Multiple industrial cameras for detecting the surface quality of particleboard are installed on one outer wall of the detection block.
[0015] Optionally, an electromagnet is installed on the outer wall of the other side of the detection block, and multiple circular grooves are opened inside the detection block. A fourth electric telescopic rod is installed inside each of the multiple circular grooves. A second probe is installed at the telescopic end of each of the multiple fourth electric telescopic rods. A third groove is opened at the center of the bottom of the detection block. Multiple rotating blocks are rotatably installed inside the third groove. A drill bit with a cross-shaped bottom is installed at the end of each of the multiple rotating blocks away from the rotating part.
[0016] The beneficial effects of this invention are:
[0017] 1. In this invention, when inspecting finished particleboard products, the cooperation between the detection mechanism, the drive mechanism, and the clamping mechanism enables the industrial camera, the first probe, and the second probe to detect the appearance quality and thickness of the particleboard. Furthermore, with the assistance of other related components, the compressive strength, wear resistance, moisture resistance, and high-temperature resistance of the particleboard can be detected simultaneously. This allows for the integration of multiple performance tests of the particleboard into a single device, facilitating a comprehensive and integrated evaluation of the particleboard's quality.
[0018] 2. In this invention, after testing the high-temperature resistance of the particleboard inside the box, the tested particleboard can be removed from the box, and water mixed with dark pigment can be injected into the box. After the new particleboard is placed inside the clamping mechanism and clamped, multiple holes are machined into the inside of the particleboard by using a drill bit that extends downward from inside the test block. Then, it is placed inside the box and soaked for 24 hours. After that, the particleboard is removed from the box and the inside is observed to see if pigment has seeped in, thus testing whether the particleboard's stain resistance is qualified.
[0019] 3. In this invention, after drilling holes in the particleboard, the heating element inside the box can be activated to heat the water inside the box, creating a high-temperature and high-humidity environment of around 40 degrees Celsius. With the help of multiple components such as the moving frame, the particleboard is moved into the box and stays there for a period of time. The high temperature and high humidity inside the box cause a significant increase in the formaldehyde release from the particleboard. The staff places formaldehyde detection equipment on the top of the box to detect the formaldehyde content emitted by the particleboard, thereby detecting whether the formaldehyde content inside the particleboard exceeds the standard, which facilitates a comprehensive evaluation of the environmental performance of the particleboard.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Example 1
[0036] Reference Figures 1-12A wood shavings finished product testing device includes a housing 1 and two fixed plates 2. The two fixed plates 2 are respectively installed on the top sides of the housing 1. Two electric push rods 4 are installed on the top of each of the two fixed plates 2. The telescopic ends of the two electric push rods 4 are connected to a top plate 5. A testing mechanism is provided at the bottom of the top plate 5. A movable frame 3 is provided between the two fixed plates 2. The movable frame 3 has a drive mechanism inside for automatically moving the wood shavings to directly below the testing mechanism. The drive mechanism includes a movable seat 15 slidably installed inside the movable frame 3. The top of the movable seat 15 is provided with a clamping mechanism for clamping and fixing the wood shavings. During the telescopic process of the two electric push rods 4, they can drive the top plate 5 and the testing mechanism to move up and down together for adjustment.
[0037] As a technical optimization of the present invention, the top of the housing 1 is provided with two cover plates 8, and the inner walls of both sides of the housing 1 are provided with two first sliding grooves 10. A first slider 9 is installed inside each of the two first sliding grooves 10, and the outer walls of both cover plates 8 are connected to the adjacent first slider 9. A first linear motor is preset inside each of the two first sliding grooves 10. The two first linear motors can drive the two first sliders 9 to move back and forth within the corresponding first sliding grooves 10, thereby causing the two cover plates 8 to move and adjust on the top of the housing 1.
[0038] As a technical optimization of the present invention, an electric heating element 11 is installed at the bottom of the box 1, and a drain pipe 12 is installed on one outer wall of the box 1. After water is injected into the box 1, the electric heating element 11 is powered on and started, so that the heat generated by the electric heating element 11 can simultaneously heat the water inside the box 1; after the water inside the box 1 is used, a preset valve inside the drain pipe 12 can be opened to quickly discharge it from the inner wall of the box 1 to the outside.
[0039] As a technical optimization of the present invention, a second sliding groove 7 is provided on the outer wall of the two adjacent fixed plates 2, and a second slider 13 is installed inside the two second sliding grooves 7. The moving frame 3 is rotatably installed between the two second sliders 13. A second linear motor is preset inside the two second sliding grooves 7. The two second linear motors can drive the two second sliders 13 to move back and forth inside the corresponding second sliding grooves 7, thereby driving the moving frame 3 to move and adjust between the two fixed plates 2. A first driving device is preset inside one of the second sliders 13. The output end of the first driving device is connected to the rotating part of one end of the moving frame 3, thereby enabling the moving frame 3 to rotate and adjust between the two second sliders 13.
[0040] As a technical optimization of the present invention, the inner walls of both sides of the movable frame 3 are provided with first grooves, and lead screws 14 are rotatably installed inside the two first grooves. The two ends of the movable seat 15 are threadedly connected to the outer walls of the two lead screws 14. Two second driving devices are preset on one side of the outer wall of the movable frame 3. The output ends of the two second driving devices are respectively connected to one end of the corresponding lead screw 14, thereby driving the two lead screws 14 to rotate inside the corresponding first grooves, and consequently driving the movable seat 15 to move back and forth inside the movable frame 3 for adjustment.
[0041] As a technical optimization of the present invention, the clamping mechanism includes a second groove 24 opened on the top of the movable seat 15. A double-headed screw 21 is rotatably installed inside the second groove 24. Two fixing brackets 16 are threadedly installed on the outer wall of the double-headed screw 21. The outer walls of the two fixing brackets 16 with their top ends close together are connected to mounting blocks 18 through two first electric telescopic rods 17. Clamping blocks 19 are rotatably installed on the outer walls of the two mounting blocks 18 with their ends close together. Limiting blocks are installed on the outer walls of the two clamping blocks 19 with their ends close together. A third driving device is pre-installed on one side of the outer wall of the movable seat 15. The output end of the third driving device is connected to one end of the double-headed screw 21, thereby driving the double-headed screw 21 to rotate inside the second groove 24, which in turn drives the two fixed frames 16 and clamping blocks 19 to move and adjust together in a direction closer or further apart. After the particleboard is placed between the two clamping blocks 19, the two fixed frames 16 drive the clamping blocks 19 to move closer together, thereby clamping and fixing both ends of the particleboard. A fourth driving device is pre-installed inside each of the two mounting blocks 18. The output ends of the two fourth driving devices are respectively connected to the rotating parts of their corresponding clamping blocks 19, thereby driving the two clamping blocks 19 and the clamped particleboard to rotate and adjust synchronously.
[0042] As a technical optimization of the present invention, two second electric telescopic rods 22 are installed inside each of the two fixed frames 16. A rectangular block 20 is installed at the telescopic end of each of the two second electric telescopic rods 22. Multiple third electric telescopic rods 25 are installed inside each of the two rectangular blocks 20. A first probe 26 for detecting the thickness of the particleboard is installed at the telescopic end of each of the multiple third electric telescopic rods 25. When the telescopic ends of the two second electric telescopic rods 22 are extended, they can drive the rectangular block 20 to move and adjust. When the telescopic ends of the multiple third electric telescopic rods 25 are extended, they can push the corresponding first probe 26 to move and adjust upwards.
[0043] As a technical optimization of the present invention, two sealing plates 23 are rotatably mounted on the top of the rectangular block 20, and torsion springs are fitted on the rotating parts of both sealing plates 23. As the telescopic end of the third electric telescopic rod 25 pushes the first probe 26 upward, it can push the two sealing plates 23, causing the two sealing plates 23 to rotate upward and open after being pushed; and after the telescopic end of the third electric telescopic rod 25 retracts downward and returns to its original position, the two sealing plates 23 can be elastically reset by the torsion springs provided on the rotating parts and rotate downward to reset.
[0044] As an optimized technical solution of the present invention, the detection mechanism includes a telescopic cylinder 6 installed on the top of the top plate 5. The telescopic end of the telescopic cylinder 6 passes through the top plate 5 and is fitted with a fixed base 27. A detection block 28 is rotatably mounted inside the fixed base 27. Multiple industrial cameras 29 for detecting the surface quality of particleboard are installed on one outer wall of the detection block 28. After the telescopic end of the telescopic cylinder 6 extends downward, it can drive the fixed base 27 and the detection block 28 to move downward synchronously for adjustment. The multiple industrial cameras 29 are all existing Korean Vieworks VC-31MCM26H industrial cameras, which have high resolution and are suitable for the identification and detection of the surface quality of the board.
[0045] As a technical optimization of the present invention, an electromagnet 31 is installed on the outer wall of the other side of the detection block 28. Multiple circular grooves 32 are opened inside the detection block 28. A fourth electric telescopic rod 33 is installed inside each of the multiple circular grooves 32. A second probe 34 is installed at the telescopic end of each of the multiple fourth electric telescopic rods 33. A third groove 30 is opened at the center of the bottom of the detection block 28. Multiple rotating blocks 35 are rotatably installed inside the third groove 30. A drill bit 36 with a cross-shaped bottom is installed at the end of each of the multiple rotating blocks 35 away from the rotating part. After the extension ends of the multiple fourth electric telescopic rods 33 are extended, they can push multiple second probes 34 to extend downward from the corresponding circular grooves 32. Multiple first drive motors are preset inside the detection block 28, and the output ends of the multiple first drive motors are respectively connected to the rotating part of one end of the corresponding rotating block 35, so as to drive the multiple rotating blocks 35 to rotate and adjust inside the third groove 30. A second drive motor is preset inside each of the multiple rotating blocks 35, and the output ends of the multiple second drive motors are connected to the corresponding drill bits 36, so as to drive the multiple drill bits 36 to rotate at high speed.
[0046] In this embodiment, multiple first probes 26 and second probes 34 are connected to a preset thickness detection device via wires. Laser sensors are integrated on multiple first probes 26 and second probes 34. By combining laser displacement sensors with probes, after multiple first probes 26 and second probes 34 come into contact with the particleboard surface, the laser sensors detect the displacement of the first probes 26 and second probes 34, and indirectly calculate the thickness of the particleboard, avoiding interference from the texture of the board surface caused by direct laser irradiation.
[0047] Furthermore, the telescopic components and drive components in this embodiment are equipped with relevant waterproof measures, such as an elastic protective cover on the surface of the telescopic components and a waterproof motor that can be used in water, to ensure that these components can be used normally in the water that enters the housing 1.
[0048] In this invention, when the user uses the device, the two lead screws 14 drive the moving seat 15 to move towards one end inside the moving frame 3, and drive the two clamping blocks 19 of the clamping mechanism to move to a position away from the top plate 5. Then, the user manually or through a preset robotic arm places the particleboard to be tested on top of the two limiting blocks, and controls the double-headed screw 21 to drive the two fixing frames 16 and the clamping blocks 19 to move towards each other. This causes the outer wall of the two clamping blocks 19 on the side that is close to each other to tightly abut against the two ends of the particleboard, thereby achieving the effect of clamping and fixing the particleboard to be tested.
[0049] Subsequently, the two lead screws 14 are controlled to move multiple components, including the movable seat 15, to directly below the top plate 5. The detection block 28 is then controlled to rotate 90 degrees counterclockwise, causing multiple industrial cameras 29 to be positioned at the bottom of the detection block 28. At this point, the telescopic end of the telescopic cylinder 6 is controlled to extend downwards, causing the detection block 28 to approach the particleboard. This allows the multiple industrial cameras 29 to automatically identify and detect the appearance quality of the particleboard. Furthermore, the rotation adjustment of the two clamping blocks 19 can be used to flip the particleboard together, and the two lead screws 14 can drive the movable seat 15 and the clamped particleboard to move horizontally for adjustment, facilitating comprehensive detection of the appearance quality of the particleboard by the multiple industrial cameras 29.
[0050] If defects are detected in the appearance quality of the particleboard, the two lead screws 14 can be controlled to move multiple components such as the moving seat 15 to one end. After the particleboard is moved to a position away from the top plate 5, the double-headed screw 21 can be controlled to move the two fixing frames 16 in opposite directions, releasing the clamping and fixing of the particleboard. This allows the particleboard to automatically fall downwards and be discharged after losing the clamping and fixing of the two clamping blocks 19.
[0051] If the particleboard has no defects in appearance, the test block 28 can be rotated and adjusted inside the fixed base 27, causing the arc surface on one side of the test block 28 to rotate to the bottom. Then, the telescopic end of the telescopic cylinder 6 is controlled to extend downward, causing the test block 28 to move slowly downward and press the particleboard clamped and fixed by the two clamping blocks 19 to test whether the maximum compressive strength of the particleboard meets the requirements. Measuring the bending strength and stiffness of the board is a key indicator for evaluating its structural safety. After the particleboard is bent or broken after the compressive strength test, it can be removed from between the two clamping blocks 19, and a new particleboard can be placed between the two clamping blocks 19 and clamped and fixed, waiting for subsequent inspections in other processes.
[0052] After testing the compressive strength of the particleboard, a new particleboard to be tested is installed between two clamping blocks 19. Then, the telescopic ends of the two second electric telescopic rods 22 inside the two fixing frames 16 are extended together, causing the two rectangular blocks 20 to move towards each other and to the bottom of the particleboard. Next, the telescopic ends of the two first electric telescopic rods 17 located on the opposite side of the mounting block 18 are retracted, causing the two clamping blocks 19 to release their clamping limits on both ends of the particleboard, allowing the particleboard to fall downwards onto the top of the two rectangular blocks 20. Then, the telescopic ends of multiple third electric telescopic rods 25 inside the two rectangular blocks 20 are extended together, causing multiple first telescopic rods 27 to retract. The head 26 extends upward from between the two sealing plates 23 and abuts against the bottom end of the particleboard. Finally, the detection block 28 is controlled to rotate and reset, and the telescopic ends of multiple fourth electric telescopic rods 33 are controlled to extend downward, pushing multiple second probes 34 to extend. With the telescopic end of the telescopic cylinder 6 extending downward, multiple second probes 34 abut against the top of the particleboard. At this time, multiple second probes 34 and the first probe 26 can automatically detect the thickness of the particleboard. With the extension and retraction of the telescopic ends of the two second electric telescopic rods 22, and the two lead screws 14 driving the moving seat 15 and the particleboard to move horizontally and adjust, so as to comprehensively detect the thickness of the particleboard at different positions.
[0053] After the original thickness of the particleboard is measured, multiple third electric telescopic rods 25 are controlled to move the corresponding first probes 26 downwards to reset, so that the two sealing plates 23 seal the top of the rectangular block 20. The two clamping blocks 19 are then rotated 90 degrees so that their bottom ends are lower than the mounting block 18 and abut against the top of the particleboard, thus confining the particleboard between the two rectangular blocks 20 and the two clamping blocks 19. After injecting sufficient water into the housing 1, the two lead screws 14 are controlled to move the moving seat 15 and other components to the left end of the moving frame 3. The two second sliders 13 are then controlled to move to the right within their corresponding second slide grooves 7, causing the moving frame 3 to move synchronously to the right a certain distance. Next, the first sliders 9 inside the two first slide grooves 10 are controlled to move the two cover plates 8 in opposite directions to open, exposing the top opening of the housing 1. Finally, control the left end of the movable frame 3 to rotate downwards into the interior of the box 1, thereby immersing the particleboard in the water inside the box 1. After the particleboard has been soaked for a period of time, control the left end of the movable frame 3 to rotate upwards to reset, causing the particleboard to be removed upwards from the interior of the box 1. Control the two first sliders 9 to move the movable frame 3 to reset, control the two lead screws 14 to move the movable seat 15 and particleboard and other components to reset, and control the two clamping blocks 19 to rotate to reset, releasing the limit on the top of the particleboard. At this time, repeat the above steps for detecting the thickness of the particleboard to re-detect the thickness of the particleboard after soaking in water. Compare the thickness data of the particleboard after soaking in water with the original thickness data of the particleboard to determine whether the water absorption thickness expansion rate of the particleboard is within the normal range, and evaluate the moisture resistance performance of the particleboard in a humid environment. An excessively high expansion rate will cause the board to deform and crack, affecting its service life.
[0054] After the particleboard has been soaked for a period of time and its thickness has been tested, in order to further test the particleboard's resistance to boiling water, the heating element 11 can be activated to heat the water inside the chamber 1. Then, the soaked particleboard is taken out from the clamping mechanism and placed inside the chamber 1 for a period of boiling water treatment. After the particleboard is boiled in boiling water for a certain period of time, it is checked whether it delaminates, cracks or deforms. The durability of the particleboard in high temperature and high humidity environment is evaluated so that the particleboard can be used in humid environments such as kitchens and bathrooms in subsequent practical applications.
[0055] During the boiling test of the particleboard inside the chamber 1, the two cover plates 8 can be controlled to move towards each other until they are not touching, so that an exhaust port for water vapor to be discharged outward is left in the center of the top of the chamber 1. After the new particleboard is installed inside the clamping mechanism, the telescopic end of the telescopic cylinder 6 can be controlled to move the original detection block 28 downward to a state of contact with the top of the particleboard. As the two lead screws 14 drive the moving seat 15 and the particleboard to move back and forth continuously, the friction surface set at the bottom of the detection block 28 can rub against the top of the particleboard, thereby testing the wear resistance of the particleboard surface and evaluating whether the wear resistance of the particleboard is qualified.
[0056] While testing the wear resistance of the particleboard surface, multiple rotating blocks 35 inside the testing block 28 can be controlled to drive the drill bits 36 to rotate downwards and extend, so that the bottom ends of the multiple drill bits 36 rub against the top of the particleboard, simulating the usage scenario of the particleboard rubbing against sharp hard objects in actual use.
[0057] In the above steps, after the multiple rotating blocks 35 drive the drill bits 36 to rotate downwards and extend to further test the wear resistance of the particleboard, the telescopic cylinder 6 is controlled to extend and retract, causing the detection block 28 to move upwards together. Then, the two rectangular blocks 20 are controlled to move towards each other, and the telescopic ends of the two first electric telescopic rods 17 are controlled to retract, so that the particleboard falls on top of the two rectangular blocks 20. A metal plate with multiple round holes in the center of its interior, and the positions of the multiple round holes corresponding to the positions of the multiple drill bits 36, is placed on top of the particleboard. The two fixing brackets 16 are controlled to move towards each other, which in turn drives the two clamping blocks 19 to move towards each other on top of the particleboard. After the two clamping blocks 19 move towards the designated position, multiple screws are placed inside the multiple round holes inside the metal plate, with the tops of the multiple screws located at the two... Between the clamping blocks 19, the telescopic cylinder 6 is controlled to extend downwards, causing the bottom ends of multiple drill bits 36 to engage with the top ends of multiple screws. As the drill bits 36 rotate and the telescopic cylinder 6 extends downwards, multiple screws can be threaded onto the particleboard, and the metal plate can be threaded onto the top of the particleboard. Finally, the side of the detection block 28 with the electromagnet 31 is controlled to rotate to the bottom, and the electromagnet 31 is energized. As the telescopic cylinder 6 extends downwards, the electromagnet 31 is magnetically attracted to the metal plate. With the upward retraction of the telescopic cylinder 6, the metal plate is subjected to the pulling force generated by the upward movement of the electromagnet 31. This allows the gripping ability between multiple screws and the particleboard to be tested, measuring the tightening ability of the screws when fixing the particleboard, which is related to the stability of the particleboard after it is used in furniture production and assembly.
[0058] During the abrasion resistance test of the particleboard in the above steps, the water vapor discharged upward from the center of the top of the box 1 can come into contact with the bottom of the particleboard. After the abrasion resistance test of the top of the particleboard is completed, the particleboard is controlled to be located in the center of the top of the box 1, so that the particleboard is in continuous contact with water vapor. This simulates the usage scenario when the particleboard is used as a cabinet in the kitchen, where it is in continuous contact with water vapor generated by the kitchen utensils below, and the moisture resistance performance of the particleboard is tested.
[0059] After the particleboard inside chamber 1 has undergone a boiling test, the water inside chamber 1 is drained by opening the valve inside the drain pipe 12. The staff can then remove the particleboard to observe for cracks or delamination. If no cracks or delamination are found, the heating element 11 inside chamber 1 is activated, and the two cover plates 8 are moved closer together to seal the top opening of chamber 1. This raises the temperature inside chamber 1 to the specified test temperature (80-180 degrees Celsius), allowing for further testing of the particleboard's high-temperature resistance. If cracks or delamination are found, the particleboard is removed from chamber 1, and new particleboard is placed inside chamber 1 for high-temperature resistance testing.
[0060] While the particleboard is being tested for high-temperature resistance inside the housing 1, a new particleboard can be placed inside the clamping mechanism. Then, the metal plate is bonded to the top of the particleboard. After ensuring that the metal plate and the top of the particleboard are firmly bonded, the detection block 28 can be controlled to rotate 90 degrees clockwise inside the fixed base 27, causing the side of the detection block 28 with the electromagnet 31 to rotate to the bottom. Then, the telescopic end of the telescopic cylinder 6 is controlled to extend downward, so that the electromagnet 31 after being energized is magnetically attracted and fixed to the metal plate. Then, the telescopic end of the telescopic cylinder 6 is controlled to retract upward, causing the electromagnet 31 to have a pulling effect on the metal plate and the particleboard, testing the bonding strength between the particleboard's internal wood chips and the adhesive, and achieving the effect of testing the internal bonding strength of the particleboard.
[0061] During the process of bonding the metal sheet to the particleboard with glue, in order to improve the curing speed of the glue, the top cover 8 of the box 1 used to test the high temperature resistance of the particleboard can be opened, so that the heat inside the box 1 can be discharged upward and the curing of the glue can be accelerated, so as to test the internal bond strength of the particleboard more quickly.
[0062] After testing the high-temperature resistance of the particleboard inside the chamber 1, the tested particleboard can be removed from the chamber 1. Water mixed with dark pigment is injected into the chamber 1. The new particleboard is placed inside the clamping mechanism and clamped. Multiple holes are then machined into the inside of the particleboard using the drill bit 36 that extends downward inside the test block 28. After soaking for 24 hours inside the chamber 1, the particleboard is removed from the chamber 1 to observe whether pigment has seeped into it, and to test whether the particleboard's stain resistance is qualified.
[0063] Meanwhile, after drilling holes in the particleboard, the heating element 11 inside the box 1 can be activated to heat the water inside the box 1, making the inside of the box 1 a high temperature and high humidity state of about 40 degrees Celsius. With the help of the cooperation between multiple components such as the moving frame 3, the particleboard is moved into the inside of the box 1 and stays there for a period of time. The high temperature and high humidity inside the box 1 cause the formaldehyde release from the particleboard to rise sharply. The staff places the formaldehyde detection equipment on the top of the box 1 to detect the formaldehyde content emitted by the particleboard at this time, so as to detect whether the formaldehyde content inside the particleboard exceeds the standard, which facilitates a comprehensive evaluation of the environmental performance of the particleboard.
