[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1. Please refer to Figures 1 - 8 The present invention discloses a strength detection device for solid wood composite floors, including a fixing frame 1. A sliding plate 12 is slidably connected to the inner side of the fixing frame 1. A hydraulic rod 13 is fixedly connected to the upper side of the sliding plate 12, and the other end of the hydraulic rod 13 is fixedly installed on the fixing frame 1. A fixing shell 2 is arranged on one side of the fixing frame 1. A fixing plate 21 is fixedly connected to the upper side of the fixing shell 2. A power motor 24 is installed on the other side of the fixing plate 21. A first gear 25 is arranged at the power output end of the power motor 24 passing through the fixing plate 21. A rotating tube 22 is rotatably connected to the lower side of the fixing plate 21. A second gear 23 is arranged at the upper end of the rotating tube 22. The second gear 23 is meshed with the first gear 25. Through the meshing of the first gear 25 and the second gear 23, the power of the power motor 24 can drive the second gear 23, so that the second gear 23 drives the rotating tube 22 to rotate. An installation block 26 is arranged inside the lower end of the rotating tube 22. A control chute 27 is opened inside the installation block 26. A control block 28 is slidably connected to the control chute 27. The control block 28 is located inside the installation block 26. Through the arrangement of the control chute 27, the sliding range of the control block 28 can be restricted, and the situation that the control block 28 deviates during the sliding process can be prevented, so that the control block 28 can always slide within the limited range. A glue application rod 5 is arranged on one side of the control block 28. A plurality of glue application nozzles 51 for applying glue to the composite board 16 are arranged on the glue application rod 5. Through the arrangement of the plurality of glue application nozzles 51, the glue can be evenly applied to the composite board 16. A placement block is arranged on the fixing frame on the same side as the fixing shell, and the placement block is located below the fixing shell. A placement groove 18 is opened on the placement block 17;

[0033] The lower end of the rotating tube 22 is fixedly connected with a scraping plate 52. The scraping plate 52 is used to scrape the glue flat on the composite board 16. Through the design of the scraping plate 52, the glue applied to the composite board 16 can be scraped flat and evenly, preventing the situation of uneven glue application; The composite board 16 after applying glue is adhered with a limiting block 15;

[0034] An annular chute 3 is opened on the lower side of the fixing plate 21. A sliding ball 4 is slidably connected to the annular chute 3. Through the design of the annular chute 3, the sliding track of the sliding ball 4 can be guided. At the same time, the sliding ball 4 is embedded in the annular chute 3, which can prevent the sliding ball 4 from getting out of the restriction of the annular chute 3. A control rod 41 is fixedly connected to one side of the sliding ball 4.

[0035] See Figure 1 Figure 1 , first place the composite board 16 to be detected on the placement groove 18 of the placement block 17, and then start the device to apply glue to the composite board 16, place the glue application nozzle 51 on one side of the composite board 16, and then start the device. See Figure 5 Figure 5 , drive the first gear 25 to rotate through the power motor 24. While the first gear 25 rotates, drive the second gear 23 to rotate together. Drive the rotating pipe 22 to rotate together through the rotation of the second gear 23. While the rotating pipe 22 rotates, drive the control block 28 to rotate together, thereby driving the glue application rod 5 and the glue application nozzle 51 to rotate on one side of the composite board 16, so that the glue can be applied to one side of the composite board 16; after the glue is applied to the composite board 16, the rotation of the rotating pipe 22 can drive the scraping plate 52 to rotate together, so that the scraping plate 52 scrapes the glue applied on the composite board 16 evenly. At the same time, the length of the scraping plate 52 is much greater than the length of the glue application rod 5. Through such a design, the scraping plate 52 can scrape the glue sprayed by the glue application nozzle 51 flat, preventing the situation that there is glue on the composite board 16 that cannot be scraped;

[0036] Subsequently, the side of the composite board 16 coated with glue is attached to the limiting block 15, and the limiting block 15 is bonded to the composite board 16 under the action of the glue, and then glue is applied to the other side of the composite board 16.

[0037] In this embodiment: through the rotation of the rotating pipe 22, the glue application rod 5 and the glue application nozzle 51 rotate together, so that the glue can be applied to one side of the composite board 16. At the same time, through the rotation of the scraping plate 52, the glue applied on the composite board 16 is evenly applied to one side of the composite board 16, so that there is enough adhesive force between the composite board 16 and the limiting block 15, preventing the situation of insufficient adhesive force, and making the subsequent detection results more accurate.

[0038] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that the coating range is insufficient when the glue application nozzle 51 applies glue to the composite board 16. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 8 Figures 1 - 8 , a through groove 211 is opened in the middle of the control block 28, an inclined groove 29 is opened on the side wall of the through groove 211, the inclined groove 29 communicates with a vertical sliding groove 210, and the inclined groove 29 and the vertical sliding groove 210 communicate with each other. Through the design of opening the through groove 211 on the control block 28, enough moving space can be provided for the control rod 41 to prevent the control rod 41 from getting stuck in the control block 28.

[0039] A sliding column 44 is provided on the control rod 41. The control rod 41 passes through the control block 28 through the through groove 211, and the control rod 41 is slidably connected to the control block 28.

[0040] The annular sliding groove 3 includes a smooth groove 31, a first inclined sliding groove 32, a straight sliding groove 33, a first wavy sliding groove 34, a second wavy sliding groove 35 and a second inclined sliding groove 36. The smooth groove 31, the first inclined sliding groove 32, the straight sliding groove 33, the first wavy sliding groove 34, the second wavy sliding groove 35 and the second inclined sliding groove 36 are interconnected. Through the guidance of the annular sliding groove 3 on the sliding ball 4, the sliding ball 4 can drive the control rod 41 to slide up and down. At the same time, the smooth groove 31, the first inclined sliding groove 32, the straight sliding groove 33, the first wavy sliding groove 34, the second wavy sliding groove 35 and the second inclined sliding groove 36 all have multiple segments, which are connected end to end, and all have a certain arc shape to form a circular sliding groove.

[0041] When the sliding ball 4 is located in the straight sliding groove 33, the control rod 41 slides down to the lowest position.

[0042] The sliding column 44 is slidably connected to the inclined groove 29 and the vertical sliding groove 210.

[0043] When the sliding column 44 is slidably connected to the inclined groove 29, the glue application rod 5 and the glue application nozzle 51 slide to the right. Through the guidance of the inclined groove 29 on the sliding column 44, when the control rod 41 drives the sliding column 44 to slide down, it can drive the glue application nozzle 51 to slide horizontally.

[0044] See Figure 7 , while the rotating tube 22 rotates, it drives the control rod 41 to rotate together through the control block 28. While the control rod 41 rotates, it drives the sliding ball 4 to slide in the annular sliding groove 3. See Figure 6 , when the sliding ball 4 slides from the smooth groove 31 into the first inclined sliding groove 32, through the guidance of the first inclined sliding groove 32 on the sliding ball 4, the sliding ball 4 gradually slides down, and at the same time drives the control rod 41 to slide down. While the control rod 41 slides down, it drives the sliding column 44 to slide in the inclined groove 29, so that the control block 28 moves horizontally to the right under the guidance of the inclined groove 29. While the control block 28 slides to the right through the control sliding groove 27, it drives the glue application rod 5 and the glue application nozzle 51 to slide together, thereby increasing the coating area of the glue application nozzle 51. When the sliding ball 4 slides from the first inclined sliding groove 32 into the straight sliding groove 33, at this time the sliding ball 4 is at the lowest position, and at the same time the sliding column 44 is located in the vertical sliding groove 210, and at this time the control block 28 has also slid to the rightmost position.

[0045] It should be noted that even if the control block 28 drives the glue application rod 5 and the glue application nozzle 51 to slide horizontally, the length of the scraping plate 52 is sufficient to smear the glue sprayed by the glue application nozzle 51, and there will be no situation where the scraping plate 52 cannot scrape the glue sprayed by the glue application nozzle 51.

[0046] In this embodiment: by controlling the lateral sliding of the block 28, the glue coating rod 5 and the glue coating nozzle 51 can be driven to slide laterally together, thereby increasing the coating area of ​​the glue coating nozzle 51 on the composite plate 16 to a certain extent, so that every corner of the composite plate 16 can be coated with glue, and then the scraper 52 is used to scrape the glue so that the glue can be more evenly coated on the composite plate 16, and the glue can be further evenly coated on the composite plate 16, thereby increasing the adhesion between the limiting block 15 and the composite plate 16, and preventing the composite plate 16 from generating stress concentration during the stretching process due to uneven glue coating. In areas with less glue, the composite plate 16 may break or be damaged prematurely due to excessive stress, thereby affecting the accurate evaluation of the overall strength test of the composite plate 16.

[0047] Embodiment 3: This embodiment is intended to promote the solution of the problem that a lot of glue will adhere to the scraper 52 during the process of scraping glue. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 - 8 The middle end of the control rod 41 is fixedly connected with a resisting round block 42, and the lower side of the resisting round block 42 is in contact with a first spring 43, and the other end of the first spring 43 is in contact with the upper side of the mounting block 26. Through the design of the resisting round block 42, the upper end of the first spring 43 can be restricted, and through the cooperation of the upper side of the mounting block 26, a certain support can be provided for the subsequent resetting of the first spring 43.

[0048] The push plate 54 is provided with a second spring 55 at one end of the control rod 41, and one end of the second spring 55 abuts against the protrusion at the lower end of the control rod 41. The design of the second spring 55 can provide power for the subsequent resetting of the push plate 54. At the same time, a slide groove is provided inside the push plate 54. The design of the slide groove can prevent the protrusion at the lower end of the control rod 41 from escaping from the restriction of the push plate 54, so that the push plate 54 and the protrusion at the lower end of the control rod 41 will not separate. The push plate 54 is located between the scraper 52 and the glue spraying nozzle 51, and the push plate 54 is slidably connected to one side of the scraper 52. A resisting rod 56 is provided on one side of the push plate 54. At the same time, through such a design, the push plate 54 can push down the glue adhering to the scraper 52 during the downward sliding process, preventing excessive glue from adhering to the scraper 52, thereby reducing the waste of glue to a certain extent.

[0049] Both ends of one side of the scraper 52 are provided with a resistance bevel block 53, which is used to resist the resistance rod 56. Through the design of the resistance bevel block 53, when the push plate 54 slides to the bottom of the scraper 52 and drives the resistance rod 56 to contact the resistance bevel block 53, the push plate 54 can slide under the action of the resistance bevel block 53.

[0050] A sliding groove 11 is provided on the inner side of the fixing frame 1, and the sliding groove 11 is slidably connected to the sliding plate 12. A fixing block 14 is provided on the other side of the sliding plate 12, and the fixing block 14 is used to engage with the limiting block 15. Through the design of the fixing block 14 and the limiting block 15, the limiting block 15 bonded with the composite plate 16 can be connected to the fixing block 14, which can reduce the shaking of the limiting block 15 and the composite plate 16 during the detection process to a certain extent, thereby increasing the accuracy of the detection result.

[0051] When the control rod 41 slides downward, the push plate 54 at the lower end of the control rod 41 will slide downward together. The push plate 54 can push the glue adhering to the scraper 52 off the scraper 52 by sliding downward. As the push plate 54 continues to slide downward, Figure 4 As shown, when one end of the resistance rod 56 on the push plate 54 contacts the wavy round block on the resistance inclined block 53, under the guidance of the wavy round block on the resistance inclined block 53, the push plate 54 slides laterally away from the scraper 52 and also causes the push plate 54 to shake. At this time, the sliding ball 4 is in the straight sliding groove 33, and the second spring 55 is deformed while the push plate 54 slides. Through the design of the second spring 55, when the subsequent control rod 41 drives the push plate 54 to slide upward, under the action of the second spring 55, the push plate 54 is driven to contact one side of the scraper 52 again; it should be noted that even if the push plate 54 drives the resistance rod 56 to slide downward to the maximum distance, the resistance rod 56 will not slide over the resistance inclined block 53.

[0052] With the continuous rotation of the rotating tube 22, when the sliding ball 4 slides from the straight chute 33 into the lower end of the vertical part of the first wave chute 34, it can drive the control rod 41 to slide rapidly upward under the action of the first spring 43, causing the sliding ball 4 to slide from the lower end of the vertical part of the first wave chute 34 into the upper end. Through the design of the vertical groove of the first wave chute 34, when the sliding ball 4 slides into the vertical groove of the first wave chute 34, it can drive the control rod 41 and the sliding ball 4 to slide rapidly upward through the vertical groove under the action of the first spring 43. The design of the vertical groove of the first wave chute 34 does not affect the sliding of the sliding ball 4. Through the rapid upward sliding of the sliding ball 4, the sliding ball 4 impacts one end of the vertical groove of the first wave chute 34, thereby vibrating the sliding ball 4, the control rod 41, and the push plate 54. Through the vibration, the glue on the push plate 54 is shaken off, so that the glue will not adhere to the push plate 54. At this time, the sliding column 44 is in the vertical chute 210. Through the design of the vertical chute 210, during the rapid upward sliding of the control rod 41, the sliding of the sliding column 44 will not be affected, the frictional force of the control rod 41 rebounding can be reduced, and at the same time, through the sliding of the sliding column 44 in the vertical chute 210, the sliding column 44 will not slide into the inclined groove 29, so that the position of the control block 28 will not deviate, enabling the glue application nozzle 51 to apply glue stably; the rotating tube 22 continues to rotate. When the sliding ball 4 slides from the first wave chute 34 into the vertical part of the second wave chute 35, it bounces the push plate 54 again, causing the glue adhered to the push plate 54 to bounce again. At the same time, as Figure 6 shown, the vertical part of the first wave chute 34 is longer than the vertical part of the second wave chute 35. Through such a design, after the push plate 54 bounces off the glue for the first time, the glue has a certain thickness at this time. When the sliding ball 4 slides on the inclined part of the first wave chute 34 and drives the push plate 54 to continue to push downward, the push plate 54 will not contact the glue again, so that when the push plate 54 bounces the glue for the second time, the glue adhered to the push plate 54 can be bounced off more cleanly.

[0053] After evenly applying the glue on the composite board 16, then bond the composite board 16 with the limiting block 15, so that the limiting block 15 can be firmly adhered to the composite board 16. See Figure 1 . Subsequently, connect the limiting block 15 with the fixed block 14. Pull the sliding plate 12 to slide in the sliding groove 11 through the hydraulic rod 13, so that the fixed blocks 14 at both ends stretch the composite board 16.

[0054] In this embodiment: while the push plate 54 slides horizontally and vibrates, the push plate 54 moves away from the scraping plate 52, so that the glue can be evenly spread out and will not accumulate on one side of the scraping plate 52. At the same time, the vibration of the push plate 54 can shake off the glue on the push plate 54, preventing the glue from sticking to the push plate 54. It can also increase the contact area between the glue and the composite board 16 to a certain extent, and can make the glue be spread more evenly. At the same time, by bouncing the push plate 54, the glue sticking to the push plate 54 can be bounced onto the composite board 16, so that all the glue can be applied to the composite board 16, thereby further enabling the glue to be evenly applied to the composite board 16, thus preventing the situation that the composite board 16 and the limiting block 15 are separated due to insufficient adhesion in some areas during the stretching process, making the test results more accurate;

[0055] Moreover, by pushing down the glue attached to the scraping plate 52 by the push plate 54 and the design that the vertical part of the first wave chute 34 is longer than the vertical part of the second wave chute 35, when the push plate 54 bounces for the second time, it will not touch the glue bounced off for the first time, making the glue on the push plate 54 be bounced off more cleanly, and can reduce the waste of glue to a certain extent.
