Description

Technical Field

[0001] This utility model relates to the field of floor testing technology, specifically to a wood floor abrasion resistance testing device. Background Technology

[0002] As a widely used floor decoration material, the wear resistance of wood flooring is a key indicator for measuring product quality and service life. Poor wear resistance will cause scratches, wear, loss of luster, or even exposure of the substrate on the floor surface, which will seriously affect the aesthetics and user experience.

[0003] The current testing method involves fixing the floor sample to be tested, applying a certain pressure to its surface with a friction head containing specific abrasive, and performing reciprocating or rotating friction motions. After a specified number of friction cycles, the wear resistance level is evaluated by observing the degree of wear on the sample surface.

[0004] Some high-precision or highly automated equipment uses servo motors, pneumatic loading, or complex transmission mechanisms to achieve reciprocating motion and pressure control, resulting in high equipment manufacturing and maintenance costs.

[0005] Some equipment uses springs, cylinders, or hydraulic pressure, which may cause pressure fluctuations or be affected by environmental factors such as air pressure and temperature, thus affecting the accuracy and repeatability of test results. Utility Model Content

[0024] Working principle:

[0025] The wood flooring sample 5 to be tested is clamped and fixed in the fixture 3.

[0026] Place the required weight 18 on the connecting plate 15 and fit it over the outside of the threaded post 16.

[0027] Loosen the limiting nut 17 upwards, so that the connecting plate 15, pressure plate 19 and weight 18 slide downwards along the guide post 11 through the sleeve 13 and linear bearing 14 under the action of gravity; adjusting the position of the limiting nut 17 on the threaded post 16 can limit the maximum downward movement distance of the pressure plate 19. The threaded connection between the limiting nut 17 and the threaded post 16 is a relatively tight connection, which prevents the limiting nut 17 from rotating easily.

[0028] Once the abrasive pad 20 at the bottom of the pressure plate 19 contacts the sample surface of the floor 5, it continues to move downwards until the required pressure is reached.

[0029] At this point, the threaded post 16 and the limiting nut 17 lock the height of the connecting plate 15, thereby pressing the pressure plate 19 and the adhesive abrasive plate 20 onto the sample surface of the floor 5 with constant pressure.

[0030] Start motor 7, which drives flywheel 8 to rotate. The connecting shaft 9 on flywheel 8 then makes a circular motion. The connecting shaft 9 drives connector 6 through connecting rod 10.

[0031] Since the connector 6 is fixed to the middle of the rear end of the clamp 3, the reciprocating swing motion of the connecting rod 10 is converted into the linear reciprocating motion of the clamp 3 in the horizontal direction.

[0032] The slider 4 at the bottom of the clamp 3 slides along the guide rail 2 on the base 1 to ensure smooth movement and accurate trajectory.

[0033] The clamp 3 causes the floor sample 5 it holds to reciprocate back and forth relative to the fixed pressure plate 19 and the adhesive grinding plate 20 above.

[0034] Under the set pressure, the surface of the floor sample 5 and the abrasive pad 20 continuously reciprocate and rub against each other. The number of frictions or the time of friction are determined by the test requirements. After the set number of frictions or the time of friction are reached, the motor 7 is turned off. The set number of frictions or the time of friction are determined by the running time of the motor 7.

[0035] Remove floor sample 5, observe and measure its surface wear under friction with the abrasive pad 20, evaluate its wear resistance, and measure the thickness of floor sample 5 before and after friction to determine the wear resistance of the floor.

[0036] Remove the weight 18, and the pressure plate 19 and connecting plate 15 will descend to their lowest point under gravity, which can be manually lifted. Then, remove the tested floor sample 5.
