Description

Technical Field

[0001] The present invention relates to the technical field of wooden floor production, and specifically discloses a device for detecting the deformation of a wooden floor after water absorption and a detection method therefor. Background Art

[0002] Water absorption and swelling deformation refers to the phenomenon that the volume of a material becomes larger and expands after absorbing liquid. The smaller the swelling amount, the stronger the anti-deformation ability of this material. The water absorption expansion rate is an extremely important quality index of wood-based panels. At present, in the production process of artificial wooden floors, quality inspection is one of the necessary processes, especially the detection of the deformation performance of wooden floors after water absorption. The existing detection process of the deformation performance of wooden floors after water absorption usually intercepts a certain amount of wood board specimens and immerses them in water. After soaking for a certain time, the ratio of the thickness difference before and after water absorption to the thickness before immersion is measured.

[0003] After retrieval, the invention patent with the publication number CN117969330A discloses a detection method and device for testing the water absorption rate of floors, including a detection unit and a sample fixing device; by placing the floor specimen in the sample fixing device, ensuring that the surface of the specimen is perpendicular to the water surface, and the specimen is not restricted in all directions, it can fully absorb moisture and expand, simulate the water absorption state, reflect the water resistance of the floor, and provide efficient and reliable test results.

[0004] Based on the above retrieval, combined with the existing technology, it is found that the existing technology uses the direct immersion method to detect wooden floors. On the one hand, it is impossible to perform simultaneous deformation detection and treatment on different types of wooden floors, and it is impossible to intuitively observe the water absorption deformation performance of different types of wooden floors. On the other hand, after the wooden floor is soaked, it is necessary to use the weighing method to detect whether there is a weight change before and after, so as to detect whether the wooden floor has water absorption and swelling deformation. However, the above method cannot measure whether it has expanded and deformed in the first time, and the manual participation in the whole detection process is relatively large, and the automation degree is relatively low. Therefore, it is necessary to propose a device for detecting the deformation of a wooden floor after water absorption and a detection method therefor to improve the above problems.

[0024] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0025] 1. Use the above-mentioned water tank, lifting assembly, heating assembly, detection box, detection piece, placement table, pressure detector, placement slot, etc. to place wooden floors of the same size and different types in different placement slots, use the forward and reverse drive in the lifting assembly to drive the two-way worm to rotate, drive the worm wheel and the threaded column to rotate, adjust the height of the U-shaped lifting plate and the placement table, so that the wooden floor enters below the liquid surface, cooperate with the heater and heating tube in the heating assembly to heat the water, so as to use high-temperature immersion to treat the wooden floor for water absorption and deformation, which brings convenience to the water absorption and deformation detection process of the wooden floor. After the immersion is completed, the placement table and the wooden floor are driven to rise by the reset action of the lifting assembly, so that the detection head in the detection piece enters the detection hole and contacts the wooden floor, and the deformation pressure transmitted by the detection head can be detected under the action of the pressure detector, so as to realize the water absorption and deformation detection of the wooden floor under the action of high-temperature immersion;

[0026] 2. By using the above-mentioned placement table, placement groove and protection component, the L-shaped card plate can be locked in the placement groove under the screw connection between the locking screw and the screw hole in the protection component, thereby restricting the wooden floor inside the placement groove, avoiding the problem of wooden floor floating during high temperature immersion, and preventing the subsequent unloading and detection operations from being affected;

[0028] 4. By using the above-mentioned box cover, built-in frame, placement table, docking port and sealing assembly, the water tank can be sealed during the immersion process under the action of the sealing assembly and the box cover. When the wooden floor is removed, the U-shaped lifting plate can be inserted into the docking port and the placement table can be fitted into the built-in frame, so as to always ensure that the interior of the water tank is in a state of nearly complete sealing.

[0057] The second implementation method:

[0058] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 On the basis of Embodiment 1, the following structure is added in this embodiment, so that this application has the function of automatically opening and closing the box cover plate 5. The specific settings are as follows: The opening and closing assembly 20 includes threaded holes opened at the bottom of the sliding plate 19, and the inner walls of two adjacent threaded holes are screwed with the same bidirectional screw rod 2004. The water tank 1 is provided with a second installation hole for the rotational installation of the bidirectional screw rod 2004. Small gears 2003 are fixedly installed at the middle positions of the bidirectional screw rods 2004.

Tooth grooves 2005 are opened at equal intervals on one side of the U-shaped lifting plate 205, and the tooth grooves 2005 are matched with the large gears 2002. With the above-mentioned opening and closing assembly 20, when the height of the U-shaped lifting plate 205 is adjusted by the lifting assembly 2, one end of the U-shaped lifting plate 205 enters the docking port 25, and the meshing effect of the tooth grooves 2005 and the large gears 2002 drives the small gears 2003 and the bidirectional screw rod 2004 to rotate, changing the positions of two adjacent sliding plates 19 on the bidirectional screw rod 2004, driving the two box cover plates 5 to move, realizing the operations of automatically closing and opening the box cover plate 5 when entering and exiting the wooden floor, without manual operation by the operator, and improving the automation effect of the entire detection device.

[0059] A method for detecting the deformation of a wooden floor after water absorption is applied to a device for detecting the deformation of a wooden floor after water absorption, and includes the following steps:

[0060] Step 1: Pour an appropriate amount of water into the water tank 1, select wooden floors of the same size but different types and place them in different placement grooves 29, and then close the protection assembly;

[0061] Step 2: Lower the height of the placement table 9 and the wooden floor through the lifting assembly 2, move the wooden floor below the liquid level in the water tank 1, and cooperate with the opening and closing assembly 20 to close the box cover plate 5;

[0062] Step 3: Start the heater 3 to heat the water in the water tank 1, keep the water temperature at 50 - 80 °C, and the heating duration is 2 h, and perform deformation treatment on the wooden floor by means of high-temperature soaking;

[0063] Step 4: Drive the placement table 9 and the wooden floor to rise through the lifting assembly 2, and cooperate with the opening and closing assembly 20 to first open the box cover plate 5, and perform deformation detection processing on the deformed wooden floor through the pressure of the detection head 8 and the pressure detector 15.

[0064] In summary, the working principle of the present invention is as follows: When in use, the operator fills an appropriate amount of water into the interior of the water tank 1, selects wooden floors of the same size but different types and places them in different placement grooves 29, and then closes the L-shaped clamping plate 30 in the protection component. The L-shaped clamping plate 30 is fixed in the placement groove 29 through the screwing action of the locking screw 32 and the screw hole 34. Then, the operator uses the positive and reverse driver 201 in the lifting component 2 to drive the rotation of the bidirectional worm 202, drive the rotation of the worm wheel 203 and the threaded column 204, and adjust the height of the U-shaped lifting plate 205 and the placement table 9 so that the wooden floor enters below the liquid level. At this time, one end of the U-shaped lifting plate 205 will enter the docking port 25, and cooperate with the meshing action of the tooth groove 2005 and the large gear 2002 in the opening and closing component 20 to drive the rotation of the small gear 2003 and the bidirectional screw 2004, change the positions of two adjacent sliding plates 19 on the bidirectional screw 2004, and drive the closing of the two tank covers 5. Then, the operator starts the heater 3 in the heating component to heat the water in the water tank 1, and thus performs the water absorption and deformation treatment on the wooden floor by means of high-temperature soaking. After soaking for a period of time, the operator drives the placement table 9 and the wooden floor to rise through the reset action of the lifting component 2, so that the detection head 8 in the detection component gradually enters the detection hole 31 and contacts the wooden floor. When the wooden floor deforms, it will squeeze the detection head 8. The pressure detector 15 receives the deformation pressure signal transmitted by the detection head 8 and transmits the pressure signal data to the display screen for display, so as to realize the water absorption and deformation detection treatment of the wooden floor under the action of high-temperature soaking.

[0065] Combined with the current actual needs, the above-mentioned implementation manner adopted by the present application, the protection scope is not limited thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of the present application still fall within the protection scope of the present invention.
