Description

Technical Field

[0001] The invention relates to the technical field of particleboard detection, and in particular to a bending strength detection machine for oriented particleboard. Background Art

[0002] Particleboard, also known as particle board, is a kind of man-made board made by cutting various branches, small-diameter wood, fast-growing wood, sawdust, etc. into pieces of certain specifications, drying them, mixing them with glue, hardener, waterproofing agent, etc., and pressing them under a certain temperature and pressure. The particles are arranged unevenly. During the production of particleboard, in order to ensure product quality, it is usually necessary to test its bending strength. After the test, an alarm signal is output and transmitted to the next process for sorting. However, particleboard is not easy to control during transportation, which makes it easy for particleboard to be damaged before testing, thereby reducing the accuracy of particleboard detection by the equipment. Particleboard is not easy to load and unload, which makes it difficult to adjust the range of bending detection during the particleboard detection process, resulting in bumps when the particleboard moves to the detection position. In addition, it is not easy to fix the particleboard during the detection process, which makes it easy for the particleboard to move during the bending strength test, making the equipment inaccurate in particleboard detection, thereby reducing the quality of particleboard production.

[0003] In summary, particleboard is difficult to control during transportation, which makes it easy for the particleboard to be damaged before testing, thereby reducing the accuracy of the equipment's particleboard testing. In addition, it is difficult to fix the particleboard during the testing process, which makes it easy for the particleboard to move during the bending strength test. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting the following technical solutions: the bending strength testing machine of an oriented strand board described in the present invention comprises a frame, a box door is rotatably connected to the outer surface of the frame, a control panel is fixedly connected to the side of the box door away from the frame, a conveyor belt frame is fixedly connected to the bottom of the inner cavity of the frame, two conveyor belt frames are arranged inside the frame through the conveyor belt frame, and further comprises:

The position of the detector connected by the hydraulic cylinder is located between the two protective components. The bottom end of the hydraulic cylinder is fixedly connected to the detector, and the top of the inner cavity of the frame is fixedly connected to the protective component;

The top of the receiving assembly passes through the frame, and the inner surface of the frame is fixedly connected with a fixing assembly;

[0007] The receiving assembly includes a bearing plate, which is fixedly connected to the bottom of the frame, a lifting cylinder is fixedly connected to the top of the bearing plate, a linkage block is fixedly connected to the top of the lifting cylinder, a guide rod is fixedly connected to the bottom of the linkage block, two guide rods are arranged on the bearing plate, and the guide rod and the lifting cylinder are distributed in a straight line on the bearing plate, and the bottom end of the guide rod passes through the bearing plate;

[0008] The installation frame is fixedly connected to the top of the linkage block, and the inner surface of the installation frame is rotatably connected with a conveyor belt.

[0009] By placing the particleboard with detection on the conveyor belt frame, the conveyor belt frame works to drive the particleboard to move, and the lifting cylinder extends on the load-bearing plate and pushes the installation frame to rise through the linkage block, so that the installation frame drives the conveyor belt to rise and stops when it is level with the conveyor belt on the conveyor belt frame. Then the conveyor belt receives the particleboard transported by the conveyor belt frame, and the guide rod is driven by the linkage block to slide on the load-bearing plate. When the particleboard moves to the appropriate position, the conveyor belt frame and the conveyor belt stop working. After the particleboard is fixed, the hydraulic cylinder extends and drives the detector down to contact the particleboard, so that the detector applies pressure to the particleboard to detect the bending strength, and transmits the detection data to the control panel on the frame. After the detection is completed, the hydraulic cylinder contracts and drives the detector to rise away from the particleboard, and at the same time releases the fixed particleboard.

[0010] Preferably, the outer surface of the guide rod is slidably connected to the bearing plate, and the bottom end of the lifting cylinder passes through the bearing plate.

[0011] Preferably, the bottom end of the hydraulic cylinder passes through the frame, and the outer surface of the mounting frame is slidably connected to the frame.

[0012] Preferably, the fixing assembly includes a side shell, which is fixedly connected to the inner surface of the frame, and the side shell is used to adjust the force of pressing the particle board. The top of the inner cavity of the side shell is rotatably connected to a rotating rod, and an adjusting motor is fixedly connected through the top of the rotating rod. The adjusting motor is fixedly connected to the side shell near the rotating rod.

Two filter frames are set inside the ventilation box, and the installation position of the filter frame is close to the blow pipe. The outer surface of the filter frame is slidably connected with a cleaning plate, and the bottom of the cleaning plate is fixedly connected with a soft plate, which is distributed in a straight line between the cleaning plate and the shielding plate through the soft plate, and the bottom of the soft plate is fixedly connected with a shielding plate. Two shielding plates are set on the ventilation box.

[0017] When the particle board stops moving, the rotating rod is driven by the regulating motor to rotate clockwise inside the side shell, so that the rotating rod drives the lifting arm to descend, and the lowering of the lifting arm pulls the telescopic rod to extend. When the squeezing roller on the lifting arm contacts the particle board, it squeezes and fixes it. The rotating rod rotates counterclockwise to drive the lifting arm to rise, so that the lifting arm rises and pushes the telescopic rod to shrink, so that the descending distance driven by the rotating rod adjusts the force of the squeezing roller to squeeze the particle board. The lifting cylinder shrinks and drives the installation frame to descend through the linkage block, so that the conveyor belt descends and separates from the particle board. The air pump inside the ventilation box works to circulate air, so that the air passes through the filter rack inside the ventilation box. After filtration, it enters the air blowing pipe, and the gas flowing through the air blowing pipe blows toward the surface of the particle board, so that the gas circulation cleans the impurities on the surface of the particle board. The air blowing pipe is installed on the lifting arm through the clamping seat, so that the lifting arm drives the air blowing pipe to move together to adjust the blowing position of the air blowing pipe. After the particle board inspection is completed, the conveyor belt frame and the conveyor belt work again to transport the particle board. The baffle plate moves on the ventilation box under the thrust, so that the baffle plate pulls the cleaning plate to move through the soft plate, and the cleaning plate moves along the filter frame for cleaning. The baffle plate is reset and the cleaning plate is pushed up by the soft plate, so that the cleaning plate is lifted and lowered along the filter frame for repeated cleaning.

[0019] Preferably, the outer surface of the air blowing pipe is slidably connected to the side shell, and the bottom of the soft board penetrates the shielding plate and extends to the inside of the shielding plate.

[0021] A protective plate is fixedly connected to the bottom of the displacement block, a sensor is fixedly connected to the outer surface of the protective plate, the outer surface of the sensor penetrates the protective plate and extends to the inside of the protective plate, and a protective block is fixedly connected to the bottom of the protective plate.

[0025] The screw is fixed on the frame through a protective shell, so that the screw is driven by the driving motor to rotate clockwise, and the clockwise rotation of the screw drives the displacement blocks to approach each other, and the displacement block drives the protective block to approach the particle board through the protective plate, and the sensor moves with the protective plate to measure the distance moved by the protective plate, and the support plate supports the elastic plate on the protective block, so that the elastic plate moves with the protective block to contact the particle board, thereby pushing the conveyor belt frame and the particle board transported by the conveyor belt to adjust the particle board during movement, and then the screw rotates counterclockwise to drive the displacement blocks away from each other, and the connecting column on the protective block drives the limiting sleeve to move, so that the buffer disk inside the limiting sleeve contacts the inner wall of the frame for buffering, so that the buffer disk contacts the frame to stop the movement of the displacement block.

[0026] The present invention provides a bending strength testing machine for oriented strand board, which has the following beneficial effects:

[0027] The oriented strand board bending strength testing machine is provided with a detector, a hydraulic cylinder, a receiving assembly, and a conveyor belt frame. The hydraulic cylinder is extended and retracted on the frame to drive the detector to rise and fall, so that the force with which the detector contacts the strand board can be adjusted, so that the detector can detect different bending strengths of the strand board under the drive of the hydraulic cylinder, thereby ensuring the accuracy of the detector's detection data of the strand board. The protective assembly and the fixed assembly can contact the strand board, so that the protective assembly restricts the moving strand board when contacting the strand board, thereby preventing the strand board from tilting during transportation, and the installation position of the receiving assembly corresponds to the detector, thereby ensuring that the strand board has sufficient movement space to perform strength testing of the strand board when subjected to the pressure of the detector.

[0028] The oriented strand board bending strength testing machine uses a load-bearing plate to contact the lifting cylinder and the guide rod on the frame, so that the load-bearing plate can share the pressure on the lifting cylinder, so that the load-bearing plate and the lifting cylinder can cooperate to limit the lifting distance of the installation frame, thereby avoiding the installation frame from falling during the lifting process. The guide rod and the lifting cylinder can cooperate to support the linkage block, so that the extension and retraction of the lifting cylinder on the load-bearing plate drives the guide rod to be lifted and lowered, thereby preventing the linkage block from tilting due to uneven force during the lifting process.

[0029] The oriented particle board bending strength testing machine drives the installation frame to move by the thrust of the lifting cylinder through the linkage block, so that the linkage block can adjust the position of the installation frame under the drive of the lifting cylinder. The linkage block can cooperate with the frame to prevent the installation frame from getting stuck during the lifting process and affecting the accuracy of the lifting movement. The conveyor belt stops when it moves with the installation frame to be horizontal with the conveyor belt frame, so that the conveyor belt and the conveyor belt frame can cooperate with each other to maintain the smooth movement of the particle board.

[0030] The oriented strand board bending strength testing machine is provided with two side connection shells inside the frame to prevent the rotating rod from slipping during rotation and affecting the movement of the lifting arm, and to prevent the moving position of the side connection shell from being affected. The rotating rod is driven by the regulating motor to rotate clockwise, so that the rotating rod rotates to drive the lifting arm to descend. When the lifting arm descends, the side connection shell can guide the movement of the lifting arm, so that the lifting arm can be adjusted according to the particle boards of different thicknesses under the drive of the rotating rod, and ensure that the lifting arm moves to fully squeeze and fix the particle board.

[0031] The oriented particle board bending strength testing machine can move with the lifting arm through the telescopic rod to keep the lifting arm stable during the lifting process, prevent the lifting arm from tilting during the lifting process, and cause insufficient extrusion of the particle board. The extrusion roller has elasticity to protect the particle board when it contacts the particle board, avoid damage to the particle board extruded by the lifting arm and the extrusion roller, thereby ensuring the integrity of the particle board extrusion position, and adjusting its own height by raising and lowering the extrusion roller.

[0032] The oriented strand board bending strength testing machine moves with the lifting arm through a clamping seat, so that when the clamping seat moves, the air blow pipe is pulled to move, so that the position of the air blow pipe is adjusted along with the movement of the lifting arm, and the residual impurities on the surface of the particle board are prevented from affecting the detection of the detector. The ventilation box is connected to the frame, so that the ventilation box uses an air pump to transport gas inside the frame, so that the gas transported by the ventilation box enters the air blow pipe.

[0033] The oriented strand board bending strength testing machine filters the separation of air pump delivery inside the ventilation box through the filter rack, so that the two filter racks filter the wind force of the air blow pipes at different positions to prevent the dust contained in the air blow pipes from affecting the cleanliness of the particle board. The baffle plate slides on the ventilation box under the thrust, so that the ventilation box reveals an opening when the baffle plate moves, so that the opening of the ventilation box can easily drop the dust filtered by the filter rack, thereby avoiding the accumulation of dust on the filter rack to affect the circulation of wind force.

[0034] The oriented strand board bending strength testing machine can reinforce the protective shell when the displacement block is moved by the screw, thereby increasing the bearing capacity of the protective shell itself. The two sensors on the protective plate can keep the protective plate moving at the same time, avoiding the influence of the protective plate moving and the adjustment of the particle board. The protective block applies pressure to the particle board as the protective plate moves, so that the protective block and the protective plate cooperate to push the particle board to adjust its position, avoiding the influence of the installation position of the protective block and the protective plate on the transportation of the particle board.

[0035] The oriented strand board bending strength testing machine supports the elastic plate on the protective block through the support plate, so that the elastic plate moves with the protective block to contact the strand board, so that the elastic plate can push the strand board under the support of the support plate to avoid the strand board being affected during the test. The elastic plate itself has elasticity, so that the elastic plate is not easily damaged when contacting the strand board, thereby ensuring the integrity of the strand board itself, and then clamping and fixing the strand board from different positions during the test.

[0036] The oriented strand board bending strength testing machine moves with the protection block via a connecting column, so that the connecting column cooperates with the limiting sleeve to increase the contact area, thereby improving the stability of the protection block when it moves. When the buffer plate moves with the limiting sleeve to contact the inner wall of the frame, the spring pressure between the buffer plate and the limiting sleeve contracts, so that the buffer plate limits the movement of the limiting sleeve when the spring contracts, and buffers the impact force generated during the contact, thereby preventing the buffer plate from being affected by the pressure when in use.

[0053] A receiving assembly 4, which is fixedly connected to the bottom of the frame 1, and is used to receive the particle board transported by the conveyor belt frame 2. The receiving assembly 4 is located between the two conveyor belt frames 2, so that the receiving assembly 4 receives the particle board transported by the conveyor belt frame 2, and the installation position of the receiving assembly 4 corresponds to the detector 7, so that the receiving assembly 4 can be lifted and lowered on the frame 1, and as the receiving assembly 4 is lifted and lowered, a movable space is generated for the particle board to be subjected to force, ensuring that the particle board has sufficient movable space to perform strength detection of the particle board when subjected to the pressure of the detector 7. The top of the receiving assembly 4 passes through the frame 1, and the inner surface of the frame 1 is fixedly connected with a fixing assembly 5;

[0054] Among them, the receiving component 4 includes a bearing plate 42, which is fixedly connected to the bottom of the frame 1, and the lifting cylinder 44 and the guide rod 43 are contacted on the frame 1 through the bearing plate 42, so that the bearing plate 42 can share the pressure on the lifting cylinder 44, so that the bearing plate 42 and the lifting cylinder 44 cooperate to limit the lifting distance of the installation frame 41, thereby avoiding the installation frame 41 from falling during the lifting process. The top of the bearing plate 42 is fixedly connected to the lifting cylinder 44, and the top of the lifting cylinder 44 is fixedly connected to the linkage block 46. The linkage block 46 is subjected to the thrust of the lifting cylinder 44 to drive the installation frame 41 to move, so that the installation frame 41 contacts the frame 1 when it moves, so that the linkage block 46 can adjust the position of the installation frame 41 under the drive of the lifting cylinder 44, so that the installation frame 41 can be installed. The mounting frame 41 is not easy to affect the particle board detection under the drive of the lifting cylinder 44. The linkage block 46 can cooperate with the frame 1 to prevent the mounting frame 41 from getting stuck during the lifting process and affecting the accuracy of the lifting movement. The bottom of the linkage block 46 is fixedly connected with a guide rod 43, and the linkage block 46 is supported by the guide rod 43 and the lifting cylinder 44, so that the lifting cylinder 44 on the bearing plate 42 can be extended and retracted to drive the guide rod 43 to lift, so that the guide rod 43 can play an auxiliary supporting role when moving with the linkage block 46, and prevent the linkage block 46 from tilting due to uneven force during the lifting process. The connection between the guide rod 43 and the bearing plate 42 can share the pressure on the lifting cylinder 44, thereby increasing the bearing capacity of the lifting cylinder 44 itself, and thus improving the service life of the lifting cylinder 44.

[0055] The mounting frame 41 is fixedly connected to the top of the linkage block 46. The inner surface of the mounting frame 41 is rotatably connected with a conveyor belt 45. The conveyor belt 45 moves with the mounting frame 41 to be level with the conveyor belt frame 2 and stops, so that the conveyor belt 45 can pick up the particle board between the two conveyor belt frames 2, so that the conveyor belt 45 and the conveyor belt frame 2 cooperate with each other to maintain the smooth movement of the particle board, and prevent the particle board from being offset or damaged when it moves from the conveyor belt frame 2 to the conveyor belt 45, thereby improving the effect of transporting the particle board.

The installation positions of the two side shells 51 correspond to the conveyor belt frame 2, so that the installation positions of the side shells 51 are used to limit the descent of the lifting arm 53 to prevent the moving position of the side shells 51 from being affected. The side shells 51 are used to adjust the force of pressing the particle board. The top of the inner cavity of the side shell 51 is rotatably connected with the rotating rod 5 2.

[0059] The lifting arm 53 is rotatably connected to the outer surface of the rotating rod 52. The position of the lifting arm 53 away from the side shell 51 is fixedly connected with a telescopic rod 54. The telescopic rod 54 is retracted along with the lifting arm 53, so that the telescopic rod 54 cooperates with the rotating rod 52 to keep the lifting arm 53 stable during the lifting process, and prevent the lifting arm 53 from tilting during the lifting process, resulting in insufficient extrusion of the particle board. The telescopic rod 54 can support the lifting arm 53 on the frame 1 to ensure that the lifting arm 53 is fully stressed during the movement. The outer surface of the lifting arm 53 is fixedly connected with a clamping seat 58.

[0060] The top end of the telescopic rod 54 is fixedly connected to the frame 1 , and the position of the lifting arm 53 close to the rotating rod 52 is slidably connected to the side shell 51 .

[0061] The clamping seat 58 is fixedly connected to a blow pipe 55 on one side away from the lifting arm 53. The clamping seat 58 moves with the lifting arm 53, so that the clamping seat 58 pulls the blow pipe 55 to move when it moves, so that the blow pipe 55 can adjust its position with the movement of the lifting arm 53, and the blow pipe 55 can blow out gas to clean the particle board when the particle board is fixed, so that the residual impurities on the surface of the particle board can be avoided to affect the detection of the detector 7, and the clamping seat 58 can protect the blow pipe 55 when it contacts the blow pipe 55, so that the blow pipe 55 is not easy to fall off during the lifting process. The end of the air blowing pipe 55 away from the card seat 58 is connected to the ventilation box 57, which is connected to the frame 1, so that the ventilation box 57 uses an air pump to transport gas inside the frame 1, so that the gas transported by the ventilation box 57 enters the air blowing pipe 55, so that the ventilation box 57 works to continuously transport the gas, so that the air blowing pipe 55 is not prone to the situation where the wind force weakens and affects the air blowing during the blowing operation, and the ventilation box 57 and the air blowing pipe 55 cooperate with each other to limit the installation position of the side shell 51, so that the ventilation box 57 and the air blowing pipe 55 play a limiting role;

[0062] A filter frame 510 is fixedly connected to the top of the inner cavity of the ventilation box 57. The filter frame 510 is used to filter the air circulating inside the ventilation box 57. The separation of the air pump is filtered inside the ventilation box 57 through the filter frame 510. Two filter frames 510 are set inside the ventilation box 57, so that the two filter frames 510 can filter the air blowing pipes 55 at different positions by wind force to prevent the dust contained in the air blowing pipes 55 from affecting the cleaning of the particle board. The filter frame 510 is protected by the ventilation box 57, so that the work of the filter frame 510 is not easily affected, and the filter frame 510 is prevented from falling off inside the ventilation box 57 to affect the filtration of the air.

The bottom of the soft plate 512 is fixedly connected with the shielding plate 59, and the shielding plate 59 is pushed to slide on the ventilation box 57, so that when the shielding plate 59 moves, the ventilation box 57 reveals an opening, so that the opening of the ventilation box 57 can drop the dust filtered by the filter frame 510, thereby preventing the dust from accumulating on the filter frame 510 and affecting the circulation of wind. When the shielding plate 59 moves, the cleaning plate 511 is pulled by the soft plate 512 to move, so that the cleaning plate 511 moves along the filter frame 510 for cleaning, so that the cleaning plate 511 can remove the dust adhered to the filter frame 510, thereby ensuring the circulation efficiency of the wind through the filter frame 510.

[0065] The protective assembly 6 includes a protective shell 61, which is fixedly connected to the top of the frame 1. Two protective shells 61 are arranged on the frame 1, so that the protective shell 61 protects the screw 62, so that the screw 62 is not easily affected by the drive motor, and the protective shell 61 is supported by the screw 62, so as to maintain the activity space inside the protective shell 61, so that the installation position of the protective shell 61 separates the lifting arm 53, and the inner surface of the protective shell 61 is rotatably connected with the screw 62, which rotates clockwise under the drive motor. , so that the screw 62 drives the two displacement blocks 63 to approach each other, and the movement of the displacement block 63 drives the protective plate 64 to move, so that the protective plate 64 approaches each other to adjust the position of contacting the particle board, and the screw 62 rotates counterclockwise to drive the two displacement blocks 63 away from each other, so that the displacement block 63 can move according to the volume of the particle board. When the screw 62 drives the displacement block 63 to move, the protective shell 61 can be reinforced, thereby increasing the bearing capacity of the protective shell 61 itself, so that the displacement block 63 is not easy to get stuck when moving, and the outer surface of the screw 62 is rotatably connected with the displacement block 63;

[0066] The protective plate 64 is fixedly connected to the bottom of the displacement block 63. The outer surface of the protective plate 64 is fixedly connected with a sensor 65. The sensor 65 moves with the protective plate 64, so that the two sensors 65 correspond to each other, which is convenient for the sensor 65 to measure the moving distance of the protective plate 64, thereby ensuring the accuracy of the movement of the protective plate 64, ensuring the subsequent pushing of the particle board, and then ensuring that the particle board is kept horizontal during transportation, preventing the particle board from tilting during the transportation process and causing errors in the detection position. The two sensors 65 are The protective plate 64 can keep the protective plate 64 moving at the same time, avoiding the protective plate 64 not moving and affecting the adjustment of the particle board. The bottom of the protective plate 64 is fixedly connected with a protective block 66, and the protective block 66 applies pressure to the particle board as the protective plate 64 moves, so that the protective block 66 and the protective plate 64 cooperate to push the particle board to adjust its position. The protective block 66 is located between the conveyor belt frame 2 and the conveyor belt 45, so that the movement of the protective block 66 is not easily affected, avoiding the installation position of the protective block 66 and the protective plate 64 affecting the transportation of the particle board.

[0067] The outer surface of the displacement block 63 is slidably connected to the protective shell 61 , and the bottom of the displacement block 63 extends to the outside of the protective shell 61 .

[0068] The inner surface of the protective block 66 is fixedly connected with a support plate 68, and the support plate 68 supports the elastic plate 67 on the protective block 66, so that the elastic plate 67 moves with the protective block 66 to contact the particle board, so that the elastic plate 67 can push the particle board under the support of the support plate 68, and ensure that the elastic plate 67 and the protective block 66 adjust the particle board. The elastic plate 67 and the support plate 68 are pushed by the protective block 66 to clamp the particle board, so that the protective block 66 and the squeezing roller 56 cooperate with each other to improve the fixing effect of the particle board, and avoid the particle board. The particleboard is affected during the inspection, and a side of the support plate 68 away from the protective block 66 is fixedly connected with an elastic plate 67.

[0069] The connecting column 69 is fixedly connected to the side of the protective block 66 away from the elastic plate 67. The connecting column 69 moves with the protective block 66, so that the connecting column 69 and the limiting sleeve 610 cooperate to increase the contact area, so that the limiting sleeve 610 and the connecting column 69 protect the side of the protective block 66 away from the elastic plate 67, and the limiting sleeve 610 and the connecting column 69 form a placement space, so that it is not easy to affect the movement of the protective block 66, thereby improving the stability of the protective block 66 when it moves, and the connecting column 69 is away from the protective block 66. One end is fixedly connected to a limiting sleeve 610, and the inner surface of the limiting sleeve 610 is slidably connected to a buffer disk 611.

When the two protective blocks 66 approach each other, the spring of the buffer disk 611 stretches to reset, so that the spring stretches to push the buffer disk 611 away from the limiting sleeve 610.

[0070] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using an oriented particle board bending strength testing machine, step 1: placing the particle board to be tested on the conveyor belt frame 2, so that the conveyor belt frame 2 works to drive the particle board to move, and the lifting cylinder 44 extends on the bearing plate 42 to push the installation frame 41 to rise through the linkage block 46, so that the installation frame 41 drives the conveyor belt 45 to rise to the level of the conveyor belt on the conveyor belt frame 2 and stops, and then the conveyor belt 45 receives the particle board transported by the conveyor belt frame 2, and the guide rod 43 is driven by the linkage block 46 to slide on the bearing plate 42, and when the particle board moves to a suitable position, the conveyor belt frame 2 and the conveyor belt 45 stop working;

[0071] Step 2: Fix the screw 62 on the frame 1 through the protective shell 61, so that the screw 62 is driven by the driving motor to rotate clockwise, and the screw 62 rotates clockwise to drive the displacement blocks 63 to approach each other, and the displacement blocks 63 drive the protection block 66 to approach the particle board through the protection plate 64, and the sensor 65 moves with the protection plate 64 to measure the distance moved by the protection plate 64;

[0072] Step 3: Support the elastic plate 67 on the protection block 66 through the support plate 68, so that the elastic plate 67 moves with the protection block 66 to contact the particle board, thereby pushing the particle board transported by the conveyor belt frame 2 and the conveyor belt 45, adjusting the particle board in the movement process, and then the screw 62 rotates counterclockwise to drive the displacement block 63 away from each other, and the connecting column 69 on the protection block 66 drives the limiting sleeve 610 to move, so that the buffer plate 611 inside the limiting sleeve 610 contacts the inner wall of the frame 1 for buffering, so that the buffer plate 611 contacts the frame 1 to stop the movement of the displacement block 63;

[0073] Step 4: When the particleboard stops moving, the protection block 66 can move to contact the particleboard, thereby fixing the particleboard. At the same time, the rotating rod 52 is driven by the regulating motor to rotate clockwise inside the side shell 51, so that the rotating rod 52 drives the lifting arm 53 to descend. The lifting arm 53 descends and pulls the telescopic rod 54 to extend. As the squeezing roller 56 on the lifting arm 53 contacts the particleboard to squeeze and fix it, the rotating rod 52 rotates counterclockwise to drive the lifting arm 53 to rise, so that the lifting arm 53 rises and pushes the telescopic rod 54 to shrink, so that the descending distance of the lifting arm 53 driven by the rotating rod 52 adjusts the force of the squeezing roller 56 squeezing the particleboard. The lifting cylinder 44 shrinks and drives the mounting frame 41 to descend through the linkage block 46, so that the conveyor belt 45 descends and separates from the particleboard.

[0074] Step 5: The air pump inside the ventilation box 57 is used to circulate the air, so that the air enters the air blowing pipe 55 after being filtered by the filter frame 510 inside the ventilation box 57. The air flowing through the air blowing pipe 55 blows toward the surface of the particle board, so that the air circulation cleans the impurities on the surface of the particle board. The air blowing pipe 55 is installed on the lifting arm 53 through the clamping seat 58, so that the lifting arm 53 is lifted and lowered to drive the air blowing pipe 55 to move together to adjust the blowing position of the air blowing pipe 55.

[0075] Step six: After the particle board is fixed, the hydraulic cylinder 3 extends and drives the detector 7 to descend to contact the particle board, so that the detector 7 applies pressure to the particle board to detect the bending strength, and transmits the detection data to the control panel on the frame 1. After the detection is completed, the hydraulic cylinder 3 contracts and drives the detector 7 to rise away from the particle board. At the same time, the fixed particle board is loosened, so that the conveyor belt frame 2 and the conveyor belt 45 can work again to transport the particle board. The baffle plate 59 is pushed to move on the ventilation box 57, so that the baffle plate 59 pulls the cleaning plate 511 to move through the soft plate 512, and the cleaning plate 511 moves along the filter frame 510 for cleaning. The baffle plate 59 is reset and pushes the cleaning plate 511 to rise through the soft plate 512, so that the cleaning plate 511 is lifted and lowered along the filter frame 510 for repeated cleaning.
