Description

Technical Field

[0001] This utility model belongs to the field of artificial board testing technology, and specifically relates to a cooling device for artificial board strength performance testing samples and clips. Background Technology

[0002] During the production of medium-density fiberboard (MDF) or particleboard, the strength properties of the raw boards must be tested. This allows for real-time adjustments to the production process based on the raw board's strength, preventing large-scale product defects after sanding. Therefore, improving the efficiency and ensuring the accuracy of raw board strength measurement is crucial. After cutting, the raw boards must be cooled to room temperature before being measured according to national standard testing methods for internal bond strength and static bending strength.

[0003] For internal bond strength testing, molten hot melt adhesive needs to be evenly applied to the surface of the clamp head to bond the specimen and the clamp head together. However, in actual testing, the clamp head needs to be heated to over 90°C to bond the board to the clamp head. At high temperatures, the adhesive inside the board will degrade, reducing the board's strength. To improve the efficiency of raw board strength testing and ensure the most accurate results possible, the temperature of the bonded board and clamp head should be significantly but steadily reduced to room temperature during the internal bond testing process, while avoiding excessive cooling of the board to prevent thermal shock. Static bending strength testing also requires rapid cooling to room temperature, ensuring that the external environment does not subject the board to excessive cooling.

[0004] Currently, two methods are generally used. One is to place the board in a ventilated area for natural cooling. The disadvantage of this method is that the cooling rate is slow, and the strength of the board will be significantly reduced due to prolonged high-temperature baking. The second method is to place the glued clips and the board to be tested in a refrigerator. The advantage of this method is that the cooling rate is fast, but because the outside temperature is too low, the board will be subjected to severe thermal shock during the cooling process, which will reduce the strength of the board. In addition, in a low-temperature environment, water droplets are easily formed on the clips and the board due to the temperature difference, and the board absorbs water, which affects its strength.

[0005] In summary, there is currently a lack of convenient and effective cooling devices to cool down the raw board and the clips with the bonding performance to be tested. Utility Model Content

The embodiments of this utility model will now be described based on its overall structure.

[0033] like Figures 1-3 As shown in the figure, this embodiment provides a cooling device for a sample and clip for testing the strength performance of engineered wood panels, comprising:

[0034] The enclosure 1 contains a water tank bottom plate 2 and a copper perforated plate 3 arranged sequentially from low to high. A support frame 4 is positioned between the copper perforated plate 3 and the water tank bottom plate 2, with the copper perforated plate 3 resting on the support frame 4 for support. The water tank bottom plate 2 and the inner wall of the enclosure 1 form a water tank. Specifically, the enclosure 1 is formed by welding five steel plates, with an open top. The support frame 4 includes four supporting angle steels and a central support member. The four supporting angle steels are screwed to the four corners of the enclosure 1. The central support member can be a support rod or a support block, with its bottom connected to the top of the water tank bottom plate 2 and its top in contact with the copper perforated plate 3. The enclosure 1 serves as the outer shell of the entire device, providing support and protection. The water tank bottom plate 2 is made of stainless steel and serves as the base of the water tank, which contains tap water and other heat-dissipating media for heat dissipation. The support frame 4 is also made of stainless steel.

[0035] Cooling channel 5 is located between copper perforated plate 3 and water tank bottom plate 2;

[0036] A water circulation device is used to transport water from the bottom of the tank to the copper perforated plate 3.

[0037] There are three cooling channels 5, which are spaced apart below the copper perforated plate 3.

[0038] The material used to prepare cooling channel 5 is copper plate.

[0039] The copper perforated plate 3 has through holes arranged in a rectangular array, with a diameter of 20mm. The copper perforated plate 3 serves to support the measuring clip 13 and connect it to the water tank below. Made of copper alloy, it is more conducive to heat dissipation of the measuring clip 13. It can be removed during maintenance, making it convenient to clean the area under the water tank.

[0040] The water circulation device includes an inlet 6, an outlet 7, an inlet pipe 8, a circulating water pump 9, and an outlet pipe 10. The inlet 6 is located on the side wall of the water tank. One end of the inlet pipe 8 is connected to the inlet 6, and the other end of the inlet pipe 8 is connected to the circulating water pump 9. The circulating water pump 9 is connected to one end of the outlet pipe 10, and the other end of the outlet pipe 10 is connected to the outlet 7. The outlet 7 is located on the side wall of the tank 1, and the height of the outlet 7 in the tank 1 is higher than that of the copper perforated plate 3.

[0041] Both the inlet pipe 8 and the outlet pipe 10 are made of copper alloy.

[0042] By continuously circulating the cooling medium in the water tank, firstly, the cooling medium can better absorb the heat from the copper perforated plate 3, the measuring clip 13, and the cooling channel 5; secondly, it can more effectively dissipate the heat in the cooling medium into the air.

[0043] The bottom plate 2 of the water tank is provided with a drain outlet 11, and the drain outlet 11 is provided with a drain valve 12.

[0044] The diameter of the drain outlet 11 is 20mm. The drain outlet 11 is connected to the outside of the tank 1, and the drain valve 12 controls whether water is released. Daily water changes or cleaning can be done through this valve.

[0045] The cross-section of cooling channel 5 is rectangular. The length and width of the cross-section of cooling channel 5 are both 52mm, and the overall length of cooling channel 5 is 680mm.

[0046] The interval between two adjacent cooling channels 5 is 50mm.

[0047] The length of cooling channel 5 can meet the placement requirements of static bending strength samples of 0-30mm thick plates. The width and height settings not only just accommodate a single sample, but also prevent the sample from being too far from the heat transfer medium, thus affecting heat dissipation.

[0048] Operating Procedure 1: During use, close the drain valve 12, fill the water tank with tap water or other cooling medium to the specified level, and then start the circulating water pump 9. Place the measuring clip 13 with the sample attached onto the copper perforated plate 3, and place the cut sample to be tested for static bending strength into the cooling channel 5. Through the flowing water, the copper perforated plate 3, and the cooling channel 5, the heat from the clip and sample is rapidly dissipated into the water, achieving cooling and reducing the impact of overheating on the strength of the material. Furthermore, the cooling process is relatively gentle, preventing thermal shock to the material due to overcooling and ensuring the accuracy of the test results. In addition, this method can reduce water consumption and save energy when measuring a small number of samples or at low temperatures through its built-in circulation system.

[0049] Operating Procedure 2: Slightly open the drain valve 12 and turn on the external water tap (water can be drawn directly from the opening on the top of the tank, connected to the outlet, or connected to the inlet to supply water to the tank). By matching the inlet speed of the external water tap with the drain valve 12, the water level in the tank can be controlled at a constant level. The operation of the circulating water pump 9 can be freely selected. Place the measuring clip 13 with the sample attached onto the copper perforated plate 3, and place the cut sample to be tested for static bending strength into the cooling channel 5. Through the external water flow, the copper perforated plate 3, and the cooling channel 5, the heat from the clip and the sample is quickly dissipated to the outside, achieving cooling and reducing the impact of overheating on the sample strength. The cooling process is relatively gentle, preventing thermal shock caused by overcooling and ensuring the accuracy of the test results. This method can quickly remove heat from the device when there are many samples or the temperature is high, improving efficiency.
