A strength testing device for solid wood composite flooring Technical Field

[0001] This invention relates to the field of flooring technology, specifically to a strength testing device for engineered wood flooring. Background Technology

[0002] Tensile testing equipment for engineered wood flooring is a key component in the field of materials mechanical property testing and experimental equipment. Its development is based on the continuous progress and improvement of materials mechanical testing methods. With the improvement of people's living standards, there are higher requirements for aesthetics and comfort. Now, many homes, outdoor floors, and platforms, such as garden landscapes and villas, are laying wood flooring to enhance their appearance. In this context, tensile testing equipment for engineered wood flooring is particularly important. It can simulate the stress conditions of engineered wood flooring under tensile conditions, accurately measuring its key mechanical properties such as tensile strength, yield strength, and elongation. This provides a scientific basis for flooring quality control, performance evaluation, and research and development. This equipment not only demonstrates the high precision and multifunctionality of materials mechanical property testing technology but also meets people's demand for high-quality wood flooring, promoting technological progress and industrial upgrading in the flooring industry.

[0003] Existing solid wood composite flooring strength testing equipment sometimes fails to apply adhesive evenly to the composite boards during the adhesive application process.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Example 1, please refer to Figures 1-8. This invention discloses a solid wood composite flooring strength testing device, including a fixed frame 1. A sliding plate 12 is slidably connected to the inner side of the fixed frame 1. A hydraulic rod 13 is fixedly connected to one side of the sliding plate 12. The other end of the hydraulic rod 13 is fixedly installed on the fixed frame 1. A fixed shell 2 is provided on one side of the fixed frame 1. A fixed plate 21 is fixedly connected to the upper side of the fixed shell 2. A power motor 24 is installed on the other side of the fixed plate 21. A first gear 25 is provided through the power output end of the power motor 24 passing through the fixed plate 21. A rotating tube 22 is rotatably connected to the lower side of the fixed plate 21. A second gear 23 is provided at the upper end of the rotating tube 22. The second gear 23 meshes 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, causing the second gear 23 to... The rotating tube 22 is rotated. The lower end of the rotating tube 22 is provided with a mounting block 26. The mounting block 26 is provided with a control groove 27. The control groove 27 is slidably connected to a control block 28. The control block 28 is located inside the mounting block 26. The control groove 27 can limit the sliding range of the control block 28 and prevent the control block 28 from deviating during the sliding process, so that the control block 28 can slide within the limited range. A glue applicator 5 is provided on one side of the control block 28. The glue applicator 5 is provided with multiple glue applicator nozzles 51 for applying glue to the composite board 16. The multiple glue applicator nozzles 51 can make the glue evenly applied to the composite board 16. A placement block 17 is provided on the lower side of the fixed shell 2. The placement block 17 is fixedly installed on one side of the fixed frame 1. The placement block 17 is provided with a placement groove 18.

[0033] A scraper 52 is fixedly connected to the lower end of the rotating tube 22. The scraper 52 is used to scrape the glue evenly on the composite board 16. The design of the scraper 52 makes the glue applied to the composite board 16 even and smooth, preventing uneven glue application. After the glue is applied, the composite board 16 is bonded with a limiting block 15.

[0034] An annular groove 3 is provided on the lower side of the fixed plate 21. A sliding ball 4 is slidably connected in the annular groove 3. The design of the annular groove 3 can guide the sliding trajectory of the sliding ball 4. At the same time, the sliding ball 4 is embedded in the annular groove 3 to prevent the sliding ball 4 from falling out of the restriction of the annular groove 3. A control rod 41 is fixedly connected to one side of the sliding ball 4.

[0035] As shown in Figure 2, firstly, the composite board 16 to be tested is placed on the placement slot 18 of the placement block 17. Then, the equipment is started to apply glue to the composite board 16, with the glue application nozzle 51 placed on one side of the composite board 16. Then, the equipment is started again, as shown in Figure 5. The power motor 24 drives the first gear 25 to rotate. Simultaneously, the first gear 25 rotates, driving the second gear 23 to rotate as well. The rotation of the second gear 23 drives the rotating tube 22 to rotate, and the rotation of the rotating tube 22 simultaneously drives the control block 28 to rotate. The glue applicator 5 and glue applicator nozzle 51 rotate on one side of the composite board 16, allowing the glue to 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 tube 22 drives the scraper 52 to rotate as well, so that the scraper 52 scrapes the glue applied to the composite board 16 evenly. At the same time, the length of the scraper 52 is much greater than the length of the glue applicator 5. Through this design, the scraper 52 can scrape the glue sprayed from the glue applicator nozzle 51 evenly, preventing the situation where there is glue on the composite board 16 that cannot be scraped.

[0036] Then, the side of the composite board 16 with glue applied is attached to the limiting block 15. Under the action of the glue, the limiting block 15 and the composite board 16 are bonded together. Then, glue is applied to the other side of the composite board 16.

[0037] In this embodiment: the rotation of the rotating tube 22 causes the glue applicator 5 and the glue applicator nozzle 51 to rotate together, so that the glue can be applied to one side of the composite board 16. At the same time, the rotation of the scraper 52 makes the glue applied to the composite board 16 evenly spread on one side of the composite board 16, so that there is sufficient adhesion between the composite board 16 and the limiting block 15, preventing insufficient adhesion and making the subsequent test results more accurate.

[0038] Example 2: This example aims to address the problem of insufficient application area when the glue spray nozzle 51 applies glue to the composite board 16. This example is an improvement based on Example 1. Specifically, please refer to Figures 1-8. A through groove 211 is provided in the middle of the control block 28, and an inclined groove 29 is provided on the side wall of the through groove 211. The inclined groove 29 is connected to the vertical sliding groove 210, and the inclined groove 29 and the vertical sliding groove 210 are interconnected. By providing the through groove 211 on the control block 28, sufficient movement space can be provided for the control rod 41, preventing the control rod 41 from getting stuck in the control block 28.

[0039] The control rod 41 is provided with a sliding post 44. The control rod 41 passes through the control block 28 through the through groove 211 and is slidably connected to the control block 28.

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

[0041] When the sliding ball 4 is located in the straight slide groove 33, the control lever 41 slides down to the bottom.

[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, the control rod 41 can drive the glue application nozzle 51 to slide laterally while driving the sliding column 44 to slide downward.

[0044] As shown in Figure 7, while the rotating tube 22 rotates, it drives the control rod 41 to rotate along with it via the control block 28. Simultaneously, the rotation of the control rod 41 causes the sliding ball 4 to slide within the annular groove 3. As shown in Figure 6, when the sliding ball 4 slides from the smooth groove 31 into the first inclined groove 32, the first inclined groove 32 guides the sliding ball 4, causing it to gradually slide downwards. This simultaneously drives the control rod 41 to slide downwards, and as the control rod 41 slides downwards, it also drives the sliding column 44 to... The control block 28 slides within the inclined groove 29, causing it to move laterally to the right under the guidance of the inclined groove 29. As the control block 28 slides to the right through the control groove 27, it also drives the glue applicator 5 and the glue applicator nozzle 51 to slide together, thereby increasing the application area of ​​the glue applicator nozzle 51. When the sliding ball 4 slides from the first inclined groove 32 into the straight groove 33, the sliding ball 4 is at its lowest point, and the sliding column 44 is located in the vertical groove 210. At this time, the control block 28 has also slid to the far right.

[0045] It should be noted that even if the control block 28 drives the glue applicator 5 and the glue applicator nozzle 51 to slide laterally, the length of the scraper 52 is sufficient to apply the glue sprayed from the glue applicator nozzle 51, and there will be no situation where the scraper 52 cannot apply the glue sprayed from the glue applicator nozzle 51.

[0046] In this embodiment: by controlling the lateral sliding of the control block 28, the glue applicator 5 and the glue applicator nozzle 51 can slide laterally together, thereby increasing the application area of ​​the glue applicator nozzle 51 on the composite board 16 to a certain extent, so that every corner of the composite board 16 can be coated with glue. Then, by scraping with the scraper 52, the glue can be applied more evenly to the composite board 16, which can further increase the adhesion between the restraining block 15 and the composite board 16. This can prevent stress concentration caused by uneven glue application during the stretching process of the composite board 16. In areas with less glue, the composite board 16 may break or be damaged prematurely due to excessive stress, thus affecting the accurate assessment of the overall strength of the composite board 16.

[0047] Example 3: This example aims to address the problem of excessive glue sticking to the scraper 52 during the glue application process. This example is an improvement upon Example 2. Specifically, please refer to Figures 1-8. A resisting block 42 is fixedly connected to the middle of the control rod 41. The lower side of the resisting block 42 abuts against a first spring 43. The other end of the first spring 43 abuts against the upper side of the mounting block 26. Through the design of the resisting block 42, the upper end of the first spring 43 can be restricted. At the same time, through the cooperation of the upper side of the mounting block 26, a certain support can be provided for the subsequent reset of the first spring 43.

[0048] A push plate 54 is slidably connected to one end of the control lever 41. A second spring 55 is installed inside the push plate 54. One end of the second spring 55 abuts against the protrusion at the lower end of the control lever 41. The design of the second spring 55 provides power for the subsequent reset of the push plate 54. At the same time, a sliding groove is opened inside the push plate 54. The design of the sliding groove prevents the protrusion at the lower end of the control lever 41 from detaching from the restraint of the push plate 54, so that the push plate 54 and the protrusion at the lower end of the control lever 41 will not separate. The push plate 54 is located between the scraper 52 and the glue spray nozzle 51, and the push plate 54 is slidably connected to one side of the scraper 52. An abutment rod 56 is provided on one side of the push plate 54. With this design, the glue adhering to the scraper 52 can be pushed down during the downward sliding process of the push plate 54, preventing excessive glue from adhering to the scraper 52, thereby reducing glue waste to a certain extent.

[0049] The scraper 52 has two ends of abutting inclined blocks 53. The abutting inclined blocks 53 are used to abut the abutting rod 56. Through the design of the abutting inclined blocks 53, when the push plate 54 slides to the bottom of the scraper 52 and drives the abutting rod 56 to contact the abutting inclined blocks 53, the push plate 54 can slide under the action of the abutting inclined blocks 53.

[0050] The inner side of the fixing frame 1 is provided with a sliding groove 11, which is slidably connected to the sliding plate 12. A fixing block 14 is provided on the other side of the sliding plate 12. 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 of the bonded composite plate 16 can be connected with 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 results.

[0051] As the control lever 41 slides downwards, it causes the push plate 54 at its lower end to slide downwards as well. This downward sliding of the push plate 54 pushes the adhesive adhered to the scraper 52 off the scraper 52. As the push plate 54 continues to slide downwards, as shown in Figure 4, when one end of the abutment rod 56 on the push plate 54 contacts the wavy block on the abutment ramp 53, guided by the wavy block on the abutment ramp 53, the push plate 54 slides laterally away from the scraper 52. At the same time, it will also cause the push plate 54 to vibrate. At this time, the sliding ball 4 is in the straight slide groove 33. While the push plate 54 is sliding, the second spring 55 will deform. 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 will be driven to re-contact one side of the scraper 52. It should be noted that even if the push plate 54 drives the abutment rod 56 to slide downward to the maximum distance, the abutment rod 56 will not slide past the abutment block 53.

[0052] As the rotating tube 22 continues to rotate, when the sliding ball 4 slides from the straight groove 33 into the lower end of the vertical section of the first wave groove 34, it can drive the control rod 41 to slide upward rapidly under the action of the first spring 43, so that the sliding ball 4 slides from the lower end of the vertical section of the first wave groove 34 into the upper end. Through the design of the vertical groove of the first wave groove 34, when the sliding ball 4 slides into the vertical groove of the first wave groove 34, it can drive the control rod 41 and the sliding ball 4 to slide rapidly through the vertical groove under the action of the first spring 43. The sliding ball 4 slides upwards. The vertical groove design of the first wave-shaped groove 34 does not affect the sliding of the sliding ball 4. The rapid upward sliding of the sliding ball 4 causes it to impact one end of the vertical groove of the first wave-shaped groove 34, thus vibrating the sliding ball 4, control lever 41, and push plate 54. This vibration dislodges the adhesive on the push plate 54, preventing it from sticking. At this time, the sliding column 44 is within the vertical groove 210. The design of the vertical groove 210 allows the control lever 41 to slide upwards rapidly... In the middle, the sliding of the sliding column 44 will not be affected, which can reduce the friction of the rebound of the control rod 41. At the same time, by sliding the sliding column 44 in the vertical sliding groove 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, and the glue spray nozzle 51 can apply glue stably; the rotating tube 22 continues to rotate, and when the sliding ball 4 slides from the first wave groove 34 into the vertical position of the second wave groove 35, it bounces the push plate 54 again, so that the ball is stuck to the push plate 54. The glue is bounced again. As shown in Figure 6, the vertical part of the first wave groove 34 is longer than the vertical part of the second wave groove 35. With this design, after the push plate 54 bounces the glue for the first time, the glue has a certain thickness. This allows the sliding ball 4 to slide at the inclined part of the first wave groove 34. When the push plate 54 continues to push downward, it will not come into contact with the glue again. This allows the glue adhering to the push plate 54 to be bounced off more cleanly when the push plate 54 bounces the glue for the second time.

[0053] After the glue is evenly applied to the composite board 16, the composite board 16 is then bonded to the limiting block 15 so that the limiting block 15 can be firmly bonded to the composite board 16, as shown in Figure 1. Then the limiting block 15 is connected to the fixing block 14, and the sliding plate 12 is pulled by the hydraulic rod 13 to slide in the sliding groove 11, so that the fixing blocks 14 at both ends stretch the composite board 16.

[0054] In this embodiment: by sliding the push plate 54 laterally and shaking it, the push plate 54 is moved away from the scraper 52, so that the glue can be spread evenly and will not gather on one side of the scraper 52. At the same time, the shaking 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 make the glue spread more evenly. At the same time, by bouncing the push plate 54, the glue stuck to the push plate 54 can be bounced onto the composite board 16, so that the glue can be applied to the composite board 16. This can further make the glue evenly applied to the composite board 16, thereby preventing the composite board 16 from separating from the limiting block 15 in some areas due to insufficient adhesion during the stretching process, making the test results more accurate.

[0055] Furthermore, the design of the push plate 54 pushing down the glue attached to the scraper 52, and the fact that the vertical part of the first wave groove 34 is longer than the vertical part of the second wave groove 35, ensures that the push plate 54 will not come into contact with the glue that was bounced down the first time when it bounces down for the second time. This allows the glue on the push plate 54 to be bounced down more cleanly, which can reduce glue waste to a certain extent.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0057] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
