Description

Technical Field

[0001] This utility model relates to the field of artificial board processing equipment technology, and in particular to a durability testing device for ecological boards. Background Technology

[0002] Eco-board is a composite board made from renewable resources or environmentally friendly materials using low-pollution processes. It is characterized by its environmental friendliness, durability, and recyclability. Durability testing of eco-board typically involves testing its bending strength. In daily life, eco-boards are commonly used to make furniture such as cabinets, wardrobes, and tabletops. However, current bending strength testing methods for eco-boards usually involve placing the board on two supports and applying force to the middle, observing for cracks or breaks. For boards of different sizes, the applied force is often in a strip or dot pattern, making it impossible to adjust the range of force application. Furthermore, no opposing compressive forces are applied to the two sides of the eco-board, failing to fully simulate the stress conditions of eco-boards in actual use, resulting in inadequate bending strength testing. Utility Model Content

[0003] This invention addresses the technical problem of the inability to adjust and switch the force application point of ecological boards, resulting in inadequate testing of bending strength, by providing a durability testing device for ecological boards.

[0004] To solve the above-mentioned technical problems, this utility model provides a durability testing device for ecological boards, including a testing platform and a telescopic cylinder. A connecting plate is vertically provided on the testing platform. One end of the connecting plate is fixedly connected to the testing platform, and the other end of the connecting plate is provided with a top plate. The connecting plate is fixedly connected to the top plate. The telescopic cylinder is fixedly connected to the lower surface of the top plate. The testing platform is also provided with a first push plate and a second push plate. A support plate is provided on the opposite side of the first push plate and the second push plate. The support plate is fixedly connected to the first push plate and the second push plate respectively.

[0005] The retractable cylinder has a first piston rod inside, and a compression device strip is fixedly connected to the lower part of the first piston rod. The bottom of the compression device strip has a flexible rubber layer, which is fixedly connected to the bottom of the compression device strip. The compression device strip also has a support frame and bolts inside. The support frame has at least three internally threaded through holes evenly distributed on it. The number of bolts is the same as the number of internally threaded through holes. The internal threads of the internally threaded through holes match the external threads of the bolts. The support frame fits against the flexible rubber layer to ensure that after the bolt rotates through the internally threaded through hole, it can push the flexible rubber layer downward.

[0006] Preferably, in the above technical solution, an inclined support plate is provided below each of the two support plates, one end of each inclined support plate is fixedly connected to the support plate, and the other end of each inclined support plate is fixedly connected to the first push plate or the second push plate.

[0007] Preferably, in the above technical solution, each of the two axial sides of the first piston rod is provided with an inclined support bar, one end of each inclined support bar is fixedly connected to the first piston rod, and the other end of the inclined support bar is fixedly connected to the extrusion device bar.

[0008] Preferably, in the above technical solution, a desktop retractable cylinder is also provided on the outer side of the second push plate. The desktop retractable cylinder is fixedly connected to the testing platform. A second piston rod is provided inside the desktop retractable cylinder. The second piston rod is fixedly connected to the second push plate. Second inclined support bars are provided on both axial sides of the second piston rod. One end of each second inclined support bar is fixedly connected to the second piston rod, and the other end of the second inclined support bar is fixedly connected to the second push plate.

[0009] Preferably, in the above technical solution, the upper surface of the testing station is provided with two parallel grooves, and each groove is provided with a row of evenly distributed threaded holes, with at least 3 threaded holes in each row.

[0010] Preferably, in the above technical solution, a slider is provided on each side of the first push plate, and both sliders are fixedly connected to the first push plate. The width of the slider matches the width of the groove to ensure that the first push plate can move horizontally on the detection table.

[0011] Preferably, in the above technical solution, the slider has a through hole in the center and a threaded knob above the slider. The external thread of the threaded knob matches the internal thread of the threaded hole to ensure that the threaded knob is threadedly connected to the threaded hole after passing through the through hole.

[0012] Compared with the prior art, the present invention has the following advantages: by adjusting the bolts in the extrusion device strip, the bolts push the flexible rubber layer downwards, so that the force application point of the extrusion device strip can be switched between strip shape and point shape, and the different positions of the force application point can also be adjusted to completely simulate the stress conditions of the ecological board in actual use.

[0013] By setting a retractable cylinder on the outside of the second push plate, opposing compressive forces can be applied to the sides of the ecological board after it has been adjusted, which can better simulate the stress environment of the ecological board during use and test its bending strength.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3As shown, this utility model discloses a durability testing device for an ecological board, comprising a testing platform 1 and a telescopic cylinder 2. A connecting plate 11 is vertically provided on the testing platform 1. One end of the connecting plate 11 is fixedly connected to the testing platform 1, and the other end of the connecting plate 11 is provided with a top plate 12. The connecting plate 11 and the top plate 12 are fixedly connected. The telescopic cylinder 2 is fixedly connected to the lower surface of the top plate 12. The testing platform 1 is also provided with a first push plate 5 and a second push plate 6. A support plate 51 is provided on the opposite side of the first push plate 5 and the second push plate 6. The support plate 51 is fixedly connected to the first push plate 5 and the second push plate 6. The retractable cylinder 2 has a first piston rod 21 inside, and a compression device strip 3 is fixedly connected to the lower part of the first piston rod 21. The bottom of the compression device strip 3 has a flexible rubber layer 32, and the flexible rubber layer 32 is fixedly connected to the bottom of the compression device strip 3. The compression device strip 3 also has a support frame 31 and bolts 33 inside. The support frame 31 has at least three internal threaded through holes 35 evenly distributed on it. The number of bolts 33 is the same as the number of internal threaded through holes 35. The internal threads of the internal threaded through holes 35 match the external threads of the bolts 33. The support frame 31 fits against the flexible rubber layer 32 to ensure that after the bolts 33 rotate through the internal threaded through holes 35, they can push the flexible rubber layer 32 downward. In this embodiment, the number of internal threaded through holes 35 and bolts 33 is preferably 5. The spacing of the bolts 33 affects the effect of the bolts 33 pushing the flexible rubber layer 32 downward. If the spacing is too long, even if two adjacent bolts 33 push downward at the same time, there will inevitably be a curvature between the flexible rubber layers 32, which cannot achieve the "point to line" conversion. If the spacing is too short, the two adjacent bolts 33 that are protruding downward are easily suspended, and cannot achieve their specific function. By adjusting the bolts 33 in the extrusion device strip 3, different force application points at the edge and middle of the ecological board can be detected, and the bending strength of the ecological board can be detected from multiple angles. The flexible rubber layer 32 can increase the contact area between the bolts 33 and the ecological board, and at the same time provide flexible protection to avoid damage to the surface of the ecological board when the bolts 33 directly contact the ecological board, which would result in inaccurate test results. Below each of the two support plates 51, there is also an inclined support plate 52. One end of each inclined support plate 52 is fixedly connected to the support plate 51, and the other end of each inclined support plate 52 is fixedly connected to the first push plate 5 or the second push plate 6. The inclined support plates 52 are triangularly connected below the support plates 51, which can improve the supporting force and stability of the support plates 51 and prevent the support plates 51 from falling off due to excessive force during the testing process of the ecological board. There is an inclined support strip 22 on each side of the first piston rod 21. One end of each inclined support strip 22 is fixedly connected to the first piston rod 21, and the other end of each inclined support strip 22 is fixedly connected to the extrusion device strip 3.The inclined support bar 22 can keep the extrusion device bar 3 in a horizontal state, and prevent the extrusion device bar 3 from being displaced on the first piston rod 21 when the single-sided bolt 33 is used as a point force application point.

[0024] In this embodiment, as Figure 1 As shown, a desktop retractable cylinder 4 is also provided on the outer side of the second push plate 6. The desktop retractable cylinder 4 is fixedly connected to the testing table 1. A second piston rod 42 is provided inside the desktop retractable cylinder 4. The second piston rod 42 is fixedly connected to the second push plate 6. Second inclined support bars 41 are provided on both axial sides of the second piston rod 42. One end of each second inclined support bar 41 is fixedly connected to the second piston rod 42, and the other end of the second inclined support bar 41 is fixedly connected to the second push plate 6. The desktop retractable cylinder 4 on the outer side of the second push plate 6 can push the second push plate 6 to move towards the first push plate 5, so as to apply force to the side of the ecological board, simulating the gravity effect of the heavy objects on the side of the ecological board when it is on a table, cabinet, etc., thereby more comprehensively simulating the stress conditions of the ecological board in reality. The second inclined support bars 41 also increase the connection contact area and connection stability of the second push plate 6 and the second piston rod 42.

[0025] In this embodiment, as Figure 5 , 6 As shown, the upper surface of the testing platform 1 has two parallel grooves 13, each groove 13 containing a row of evenly distributed threaded holes 14, with at least three threaded holes 14 in each row. A slider 53 is provided on each side of the first push plate 5, and both sliders 53 are fixedly connected to the first push plate 5. The width of the slider 53 matches the width of the groove 13 to ensure that the first push plate 5 can move horizontally on the testing platform 1. A through hole 55 is provided in the center of each slider 53, and a threaded knob 54 is provided above the slider 53. The external thread of the threaded knob 54 matches the internal thread of the threaded hole 14 to ensure that the threaded knob 54 is threadedly connected to the threaded hole 14 after passing through the through hole 55. During operation, adjust the relative position of the first push plate 5 on the testing table 1 according to the specific size of the ecological board and the testing area. After adjustment, align the through holes 55 on both sides of the first push plate 5 with the threaded holes 14 on the testing table 1, and then insert the threaded knob 54 and tighten it with the thread to fix the first push plate 5.

[0026] This invention features an adjustable extrusion device strip. Adjusting the bolts within the strip causes them to push downwards, lifting the flexible rubber layer. The force application point of the extrusion device strip can be switched between a strip shape and a point shape, or its position can be adjusted to fully simulate the stress conditions of the ecological board in actual use. A retractable tabletop cylinder located on the outer side of the second push plate applies opposing extrusion forces to the sides of the ecological board after it has been adjusted, further simulating the stress environment of the ecological board and testing its bending strength.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
