Description

Technical Field

[0001] The utility model relates to the technical field of wood product detection, in particular to a device for detecting water absorption and expansion of wood products. Background Art

[0002] Wood products refer to various products obtained by processing and manufacturing wood, and common ones include wooden furniture, floors, handicrafts, etc. For wood, the water absorption thickness expansion rate is an indicator of whether the wood is "moisture-proof". Wood with a smaller water absorption expansion rate will have a smaller expansion thickness in a humid environment and is less likely to have defects such as wood warping. Conversely, the higher the water absorption thickness expansion rate, the more likely the wood will expand in a humid environment. The water absorption thickness expansion rate of wood is generally detected by a water absorption expansion detection device.

[0003] In the prior art, there is a wooden floor water absorption expansion detection device with announcement number CN220381132U, which includes a detection box, a lifting immersion frame with a lifting function, and a positioning mechanism connected to the lifting immersion frame for clamping the floor to be tested. The positioning mechanism is used to clamp and fix the floor to be tested, and the lifting immersion frame is used to immerse the floor in the water of the detection box, so as to obtain the expansion thickness of the floor after immersion.

[0004] However, in the above scheme, since the floor is located below the top plate, when the thickness of the floor needs to be detected during the immersion process, the lifting immersion rack needs to be lifted to expose the floor, and then the thickness of the floor needs to be measured. After the measurement is completed, the immersion rack and the floor need to be put back into the water. This process is cumbersome and inconvenient to detect the thickness of the floor when it is immersed in water. Utility Model Content

[0005] The utility model aims to provide a device for detecting water absorption and expansion of wooden products, which can conveniently measure the thickness of a sample to be tested during immersion in water.

[0006] To achieve the above-mentioned purpose, a device for detecting water absorption and expansion of wooden products is provided, which comprises: a frame, the frame comprises a mounting platform and a detection box, the detection box is located above the mounting platform; a lifting and immersion frame, the lifting and immersion frame comprises a top plate, a lifting member, a clamping member and a limiting member, the lifting member, the clamping member and the limiting member are each provided with two groups, the two lifting members are arranged on the mounting platform at intervals and connected to the top plate, the top plate is slidably arranged in the detection box, the top plate is provided with a first through groove along the length direction, the two clamping members each comprise a measuring rod penetrated through the first through groove, a bottom plate arranged parallel to the top plate is provided at the bottom of the measuring rod, and a scale structure is provided on the measuring rod, the top plate is provided with a second through groove along the width direction, two second through grooves are provided, the two second through grooves are respectively provided on both sides of the first through groove, and the two limiting members are slidably penetrated through the corresponding second through grooves; a temperature regulating component, the temperature regulating component is located at the bottom of the detection box.

[0007] The working principle and effect of the above scheme are as follows: the side wall of the detection box is made of transparent material, water is placed in the detection box, and the temperature adjustment component can adjust the temperature of the water in the detection box; when working, the lifting member is used to move the top plate to the top of the detection box, and the two clamping members are slid respectively to place the wood to be tested on the two bottom plates (it is necessary to ensure that the distance between the two measuring rods is greater than the length of the wood to be tested, and the distance between the opposite surfaces of the two bottom plates is less than the length of the wood to be tested), and the two limit members are slid so that the two limit members are close to the side of the wood to be tested respectively; the distance from the top surface of the bottom plate to the starting point of the scale structure is the sum of the heights of the measuring seat and the top plate; when measuring, the measuring rod is pulled upward so that the wood is clamped between the bottom plate and the top plate. At this time, the scale reading corresponding to the top of the measuring seat is the thickness of the wood. After the measurement is completed, the bottom plate is moved downward so that the distance between the bottom plate and the top plate is greater than the thickness of the wood.

[0008] By arranging a clamp on the top plate, when the wood is immersed in water, the measuring rod is pulled upward so that the wood to be measured is clamped between the bottom plate and the top plate, and the thickness of the wood is obtained by observing the reading on the scale structure through the side wall of the detection box. In this process, there is no need to take the wood and other structures out of the water and then measure the thickness of the wood, so that the thickness of the wood to be measured can be measured during the immersion process.

[0009] According to the device for detecting water absorption and expansion of wooden products, the lifting component includes a support frame, a lifting rod, a sleeve and a fixing bolt. The support frame is arranged on a mounting platform, the lifting rod is passed through the support frame, the bottom end of the lifting rod is connected to the top plate, the sleeve is fixedly arranged on the support frame, the sleeve is sleeved on the lifting rod, the lifting rod is sequentially provided with a plurality of through holes along the vertical direction, and the fixing bolt is passed through the sleeve and the corresponding through holes.

[0010] When the lifting member is working, loosen the fixing bolt so that the lifting rod can move along the support frame. When fixing the lifting rod on the support frame, use the fixing bolt to pass through the sleeve and the corresponding through hole, tighten the fixing bolt, and then fix the lifting rod.

[0011] According to the device for detecting water swelling of wooden products, a plurality of limiting holes are sequentially opened on both sides of the first through groove and the second through groove.

[0012] A first through slot is opened along the length direction of the top plate, and a plurality of limit holes are opened in sequence on both sides of the first through slot. When the clamping member slides along the first through slot, it can be fixed according to the corresponding limit holes; two second through slots are opened along the width direction of the top plate, and the two second through slots are respectively arranged on both sides of the first through slot, and limit holes are opened in sequence on both sides of the two second through slots. When the limit member slides along the second through slot, it can be fixed according to the corresponding limit holes.

[0013] According to the device for detecting water absorption and expansion of wooden products, the clamping member further includes a measuring seat, a first positioning bolt and a second positioning bolt. The measuring seat is sleeved on the measuring rod. The first positioning bolt is laterally fitted and penetrates through the side wall of the measuring seat and stops at the measuring rod. The second positioning bolt is vertically fitted and penetrates through the measuring seat, and the second positioning bolt is fitted and connected with the limiting holes on both sides of the first through groove.

[0014] When the clamping member is fixed, move the measuring rod to a suitable position, rotate the first positioning bolt so that the end of the first positioning bolt abuts against the measuring rod, rotate the second positioning bolt so that the end of the second positioning bolt extends into the corresponding limiting hole and cooperates with the limiting hole to fix the measuring rod on the top plate.

[0015] According to the device for detecting water absorption and expansion of wooden products, the limiting component includes a limiting rod, a limiting block and a limiting bolt, the limiting rod is passed through the second through slot, the limiting block is located at the top of the limiting rod, the limiting bolt is vertically passed through the limiting block, and the limiting bolt is matched and connected with the limiting holes on both sides of the second through slot.

[0016] When the limiting piece is working, the limiting rod is slid along the second through groove to make the limiting rod close to the side of the wood, and the limiting bolt is rotated to make the end of the limiting bolt cooperate with the limiting hole to connect, so as to fix the limiting piece on the top plate; by setting the limiting rod, the wood can be prevented from moving in the width direction during immersion.

[0017] According to the device for detecting water absorption and expansion of wooden products, the temperature regulating assembly includes a heating tube and a partition, both of which are located in a detection box. The heating tube is U-shaped, and both ends of the heating tube are connected to the detection box. The partition is located above the heating tube and connected to the detection box.

[0018] When the temperature regulating component adjusts the temperature of the water in the detection box, the heating tube adjusts the temperature of the water in the heated detection box. The partition can prevent the lifting parts and other structures from colliding with the heating tube when they are extended into the water. The heating tube can keep the temperature of the water in the detection box within a certain range, thereby preventing the wood from absorbing water due to changes in water temperature when the wood is immersed.

[0019] According to the device for detecting water absorption and expansion of wooden products, a stirring member is arranged on the mounting platform, and the stirring member includes a driving motor, a rotating shaft and a stirring paddle. The driving motor is arranged on the mounting platform, and the rotating shaft is connected to the driving motor and passes through the bottom of the detection box. The stirring paddle is located in the detection box and below the partition, and the stirring paddle is fixedly connected to the rotating shaft.

[0020] When the stirring element is working, the drive motor is started, and the drive motor drives the rotating shaft and the stirring paddle to rotate. The rotating stirring paddle can drive the water in the detection box to flow, and the flowing water can evenly detect the water temperature of various parts in the box, thereby avoiding overheating of the water near the heating tube.

[0021] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
