Description

Technical Field

[0001] This utility model relates to the field of simulation testing device technology, specifically to a simulation testing device for the shrinkage and swelling of solid wood flooring. Background Technology

[0002] Solid wood flooring is susceptible to damage during use due to moisture in the air or seeping into the floor. When it absorbs water, it expands, and when it dries, it shrinks, a process that can easily cause damage. To verify the wood flooring's ability to expand and contract with moisture, a simulation experiment is needed. However, existing technologies use a clamping mechanism to hold the wood flooring in the test solution, which can affect the expansion of the flooring and thus the accuracy of the test. Therefore, this invention provides a device for simulating the expansion and contraction of solid wood flooring. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2 As shown, a solid wood flooring shrinkage and swelling simulation test device includes: a base 1, on which a immersion chamber 2 and a drying chamber 3 are spaced apart. The immersion chamber 2 is located on one side of the drying chamber 3. The two are the same size and both have an inlet and outlet at the top. The inlet and outlet dimensions of the two are also the same.

[0022] A support frame 4 is provided on the base 1, and the top of the support frame 4 extends above the soaking tank 2. A mounting top seat 5 is provided on the top of the support frame 4.

[0023] like Figure 4 and Figure 5 As shown, the top of the mounting base 5 is recessed downwards to form a sliding groove 6, and a sliding mounting seat 7 is slidably disposed within the sliding groove 6. The sliding mounting seat 7 is threadedly connected to a second lead screw 17 disposed within the sliding groove 6, and one end of the second lead screw 17 is connected to a drive motor 18 disposed on the mounting base 5. The drive motor 18 drives the second lead screw 17 to rotate, thereby causing the sliding mounting seat 7 to move back and forth.

[0024] like Figure 3 As shown, a downward-facing lifting cylinder 8 is provided on the sliding mounting base 7. The piston rod of the lifting cylinder 8 extends below the sliding mounting base 7, and the end of the piston rod is connected to a mounting plate 9. Two sliding grooves 10 are provided on the mounting plate 9, and the two sliding grooves 10 are symmetrically arranged along the center line of the mounting plate 9. Two vertical fixing rods 11 are slidably installed in each sliding groove 10. The top end of the fixing rod 11 is located above the mounting plate 9, and the bottom end is located below the mounting plate 9.

[0025] Connecting platforms 12 are provided at both ends of the sliding groove 10 on the top of the mounting plate 9. A first lead screw 13 is rotatably connected between the two connecting platforms 12. The surface of the first lead screw 13 is provided with two sets of threads in different directions, and one end of the first lead screw 13 extends to the outside of the connecting platform 12, and a rotating handle 14 is provided at that end. The two sets of threads on the surface of the first lead screw 13 respectively cooperate with two fixed rods 11 to realize the two fixed rods 11 moving towards or away from each other. By rotating the handle 14, the first lead screw 13 is rotated, thereby causing the two fixed rods 11 to move towards or away from each other.

[0026] Two lifting cylinders 8 are symmetrically arranged along the centerline of the sliding mounting base 7 to ensure the strength of the connection structure and the stability of its movement. Two sliding grooves 10 are located outside the two lifting cylinders 8. The lifting cylinders 8 drive the mounting plate 9 and its upper structure to rise and fall, allowing it to extend into the immersion chamber 2 and the drying chamber 3. When fully inserted into the immersion chamber 2 or the drying chamber 3, the mounting plate 9 is positioned on the top surface of the immersion chamber 2 or the drying chamber 3. To improve integration and airtightness, the inlet and outlet are adapted to the mounting plate 9, which blocks the inlet and outlet.

[0027] The mounting base 5 is provided with a cover plate 19, which covers the sliding groove 6, and has a slot in the middle for the lifting cylinder 8 to move back and forth.

[0028] One of the two fixed rods 11 has a sleeve portion 15 at its bottom facing the other fixed rod 11, and the other fixed rod 11 has an inner rod 16 at its bottom that fits into the sleeve portion 15. The inner rod 16 is inserted into the sleeve portion 15, connecting the bottoms of the two fixed rods 11 together to form a placement frame structure. Solid wood flooring is placed on the placement frame structure and moves and rises accordingly without the need for a clamping mechanism, which improves the accuracy of the test.

[0029] Working process: Adjust the distance between the two fixing rods 11 according to the size of the solid wood flooring, then place the solid wood flooring on the fixing rods 11, start the lifting cylinder 8, and drive the mounting plate 9 and its upper structure and the solid wood flooring to descend together until the solid wood flooring is completely submerged in the immersion chamber 2. Stay for a period of time to simulate the expansion of the solid wood flooring by absorbing moisture. Then the lifting cylinder 8 drives the solid wood flooring to rise, and the drive motor drives the sliding mounting base 7 and the solid wood flooring to move above the drying chamber 3. Then the lifting cylinder 8 drives the solid wood flooring to descend into the drying chamber 3 to simulate the expansion and then drying and shrinkage.
