[0036] The specific workflow is as follows:
[0037] When the strength test is performed on the wood composite board sample, the composite board sample to be tested is placed on the contact component 4, and the strength test is performed on the composite board sample by the test component 1, so that the data acquisition device 2 records and transmits the data. At the same time, when the composite board sample is tested, when the test force is too large, the composite board will be broken, so the debris generated by the composite board sample is collected by the collection component 5. At the same time, when the strength test is performed on the composite board sample, the surrounding staff can be protected;
[0038] By placing the composite plate sample on the contact component 4, turning on the motor 15, and driving the detection block 14 to move downward through the output end of the motor 15 until it contacts the composite plate sample, the strength of the composite plate sample on the contact component 4 is tested;
[0039] When performing strength testing on the composite plate sample, the composite plate sample is placed on two rollers 47, and the output end of the motor 15 drives the detection block 14 to perform extrusion testing on the composite plate sample. When the composite plate sample is subjected to extrusion force, the force-bearing point of the composite plate sample is bent and depressed, so that the composite plate sample and the roller 47 are in rotational contact, thereby reducing the friction between the composite plate sample and the roller 47. At the same time, when performing strength testing on the composite plate sample, it is squeezed at a specified speed until the sample is destroyed, and the maximum load at the time of destruction is recorded, so that a large amount of composite plate debris will adhere to the side of the roller 47 in contact with the composite plate sample, and then in the subsequent strength test, the side of the roller 47 needs to be cleaned to avoid residual composite plate debris on the roller 47. In order to avoid interfering with the subsequent strength test, after the strength test of the composite plate sample is performed, the roller 47 is rotated so that the roller 47 contacts and rotates with the contact block 45. At the same time, a plurality of protrusions are provided on the side of the contact block 45 so that when the contact block 45 contacts and rotates with the roller 47, the contact block 45 can clean and scrape off the composite plate waste adhered to the side of the roller 47, thereby avoiding the waste residue remaining on the roller 47. At the same time, when the composite plate sample is tested, when the composite plate sample is placed on the roller 47, the first spring 46 drives the contact block 45 to counteract the groove on the side of the roller 47, and limits the position of the roller 47, thereby avoiding the roller 47 from sliding when contacting with the composite plate sample, which will interfere with the strength test.
[0040] Since the composite board sample is squeezed at a prescribed speed until the sample is destroyed during the strength test, a large amount of wood chips are prevented from remaining on the inner side of the bottom plate 11 and accumulating in the bottom plate 11. When the composite board sample is subjected to the strength test, the suction machine 53 is turned on, and the suction force generated by the suction machine 53 is used to drive the wood chips generated when the sample is destroyed into the collection box 51 through the mesh plate 52, and accumulate on the baffle 54 for collection. At the same time, a rotating mechanism 55 is provided on the baffle 54, so as to prevent the wood chips entering the collection box 51 from accumulating in large quantities in the ventilation area of the baffle 54, thereby interfering with the normal suction work of the suction machine 53 and thus interfering with the collection work.
[0041] When the air sucker 53 is working, the suction force generated by the air sucker 53 causes the rotating plate 551 to rotate on the baffle 54 through the rotating shaft 552, so that the rotating plate 551 drives the cleaning brush 553 to clean the top of the mesh plate 52, thereby preventing a large amount of wood chips from accumulating in the ventilation area of the mesh plate 52 and causing the baffle 54 to be blocked. At the same time, when the rotating plate 551 rotates on the baffle 54, the centrifugal force causes the bent rod 555 to rotate in the square groove 556, which can clean the wood chips sucked by the air sucker 53. The sawdust entering the collecting box 51 is contacted and rotated by the force, so that the sawdust entering the collecting box 51 is diffused around the baffle plate 54, so as to prevent a large amount of sawdust from accumulating at the ventilation opening of the mesh plate 52. At the same time, the bent rod 555 is rotated in the rotating groove 554, and square grooves 556 are provided on both sides of the bent rod 555, so that the flocculent dust entering the collecting box 51 following the sawdust can be hooked through the square grooves 556, so as to prevent the flocculent dust entering the collecting box 51 following the sawdust from the outside from being entangled with the rotating shaft 552.
[0042] When the composite plate sample is placed on the roller 47 for strength testing, the folding plate 32 is stretched downward and closed to avoid the debris generated when the composite plate is broken during the strength test from splashing onto the staff. At the same time, when the output end of the motor 15 drives the detection block 14 to perform strength testing on the composite plate sample, the detection block 14 moves downward and drives the cleaning mechanism 35 to move in the sliding groove 34 through the connecting shaft 33, so that the cleaning mechanism 35 cleans the side of the transparent plate 36, thereby avoiding the waste debris generated when the composite plate is broken during the strength test of the composite plate sample from splashing onto the transparent plate 36, thereby interfering with the staff's viewing line of sight.
[0043] When the detection block 14 drives the cleaning plate 351 to move downward through the connecting shaft 33, the cleaning plate 351 slides downward in the sliding groove 34 through the slider 352, so that the cleaning cylinder 354 can clean and wipe the side of the transparent plate 36, thereby avoiding excess grease from remaining on the side of the transparent plate 36 close to the detection block 14, so that the waste chips when the composite plate is broken during the strength test will be more easily adhered to the transparent plate 36. When the detection block 14 finishes the strength test on the composite plate sample, the detection block 14 is driven to move upward through the output end of the motor 15. At the same time, the detection block 14 drives the connecting plate 353 to move upward through the connecting shaft 33. By arranging a scraper 355 at the bottom of the connecting plate 353, the scraper 355 can clean and scratch the transparent plate 36 when the connecting plate 353 moves upward, thereby avoiding a large amount of wood chips remaining on the transparent plate 36 during the strength test and being difficult to fall off naturally, thereby adhering to the transparent plate 36 for a long time, which will interfere with the staff's observation of the inside of the equipment.
