Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of OSB board testing, in particular to a cutting equipment for OSB board edge density testing. BACKGROUND

[0002] OSB board is a kind of multi-layer structure of artificial board material which is made of long strip wood chips (shavings) after drying, applying waterproof adhesive, and then laying according to the specific direction of the surface layer shavings horizontally and the core layer shavings vertically, and then forming by high temperature and high pressure hot pressing. Due to its high strength, good dimensional stability, low cost and other advantages, it is widely used in building structure materials, packaging trays, furniture base materials and other fields. Since its mechanical properties (such as bending strength, elastic modulus, and nail holding force) are closely related to the internal density distribution, especially the density uniformity of the edge area and the density gradient in the thickness direction, which directly affects the edge load capacity and processing performance of the board, therefore, in quality control and research and development testing, it is necessary to accurately sample the OSB board to analyze the density changes at different depths.

[0003] The existing cutting equipment for OSB board edge density testing is usually equipped with only a single direction rotating cutting knife. During operation, the whole OSB board is first fixed horizontally by a clamp, and then the board is fed along the horizontal direction, and a complete vertical cutting is completed by a high-speed rotating disc saw to obtain a complete cross section. However, if the density gradient in the thickness direction is to be studied, the existing equipment cannot directly realize layered cutting. The operator must manually release the clamping mechanism, take out the board, re-adjust the position, and in the absence of a special vertical clamping device, hold the board close to the high-speed rotating cutting knife for layer-by-layer cutting. This process is not only extremely inefficient and labor-intensive, but also has serious drawbacks. On the one hand, manual holding cannot guarantee that the cutting plane is parallel to the board surface, which can easily cause uneven layer thickness, inclined cutting surface or local edge collapse, resulting in distorted density test data. On the other hand, the high-speed rotating cutter operates exposed, and the operator's hand is close to it, which can easily cause cuts, flying debris injuries and other safety accidents. In addition, when the OSB board needs to be further cut into multiple standard test small pieces, the existing process requires unlocking the clamp again after completing the vertical cutting, re-flipping, aligning and clamping the cut strip sample, and then performing horizontal cutting. The repeated clamping-cutting-disassembly cycle not only consumes time and effort, but also introduces cumulative errors due to inconsistent positioning reference each time, resulting in large size deviation of the final sample, untraceable position, and serious impact on the repeatability and scientificity of the test results. SUMMARY

[0004] In view of the above, the present application provides a cutting device for OSB board edge density testing, which can realize cutting and layering of OSB boards, and the OSB boards are fixed by the clamping mechanism during the whole cutting process, and the height of the cutting knife can be adjusted for layering cutting of OSB boards of different thicknesses, and the vertical and horizontal block cutting of the OSB boards can be realized without unlocking the clamping mechanism after clamping and fixing the OSB boards once, which not only completely eliminates the safety risks and operation errors of manual cutting, but also ensures uniform thickness, smooth edges and corresponding positions of each layer of samples, and greatly improves the sample preparation efficiency.

[0007] As a further improvement of the application, the self-adaptive clamping and fixing mobile mechanism comprises a plurality of vertical guide frames arranged inside the cutting box, a sliding plate is slidably arranged between the outer arc surfaces of the plurality of vertical guide frames, a plurality of horizontal guide frames are arranged on the upper side of the sliding plate, a placing box is slidably arranged between the outer arc surfaces of the plurality of horizontal guide frames, two clamping and fixing frames are rotationally arranged inside the placing box through a rotating column, a clamping worm wheel is fixedly arranged on the outer arc surface of each rotating column, a clamping worm is rotationally arranged inside the placing box, the front and rear thread directions of the clamping worm are opposite, the plurality of clamping worm wheels are jointly meshed and connected with the clamping worm, a hand wheel is arranged at the front end of the clamping worm, a position adjusting driving mechanism for driving the position adjustment of the placing box is arranged inside the sliding plate, the position adjusting driving mechanism comprises a fixed cavity frame arranged inside the sliding plate, an avoiding slot is arranged on the right side of the cutting box and matched with the fixed cavity frame, a telescopic cavity frame is slidably arranged inside the fixed cavity frame, the upper side of the telescopic cavity frame is connected with the lower side of the placing box, an adjusting screw is rotationally arranged inside the fixed cavity frame, the inside of the telescopic cavity frame is threadedly connected with the adjusting screw, and an adjusting motor is arranged on the right side of the fixed cavity frame.

[0008] As a further improvement of the application, the lower side of the cutting box is provided with a support frame, the cutting box and the support frame are fixed by welding, and a plurality of mounting holes are respectively arranged at the four corners of the inside of the support frame As a further improvement of the application, the upper side of the cutting box is provided with a protective cover, and a chip suction shell is arranged in the mounting opening arranged in the inside of the protective cover.

[0009] As a further improvement of the application, a collecting box is slidably arranged in the sliding slot arranged in the inside of the cutting box, chip guide plates are arranged on the left and right sides of the mounting frame plate, and the two chip guide plates are correspondingly arranged and inclined.

[0010] Compared with the prior art, the application has at least the following beneficial technical effects: Firstly, the OSB board to be cut is placed on the placing box, and the target cutting position is accurately aligned with the cutting knife, then the hand wheel is rotated to drive the clamping worm, which drives the clamping worm wheel and the clamping and fixing frame on the rotating column to rotate towards each other, so that the flexible OSB board is pressed on the upper surface of the OSB board, the worm and worm gear mechanism has self-locking characteristics, can firmly and stably clamp different thickness and size plates, and avoids displacement caused by vibration or feeding force during cutting; then the cutting motor is started to make the cutting knife on the rotating shaft rotate at high speed, and the operator slowly pushes the placing box, the bottom sliding plate of the placing box moves along a straight line stably under the precise limiting of the vertical guide frame, so as to ensure that the OSB board contacts the rotating cutting knife in a constant posture, and realizes accurate cutting sampling with flatness, no deviation and low burr.

[0011] Secondly, when the OSB board needs to be cut in the thickness direction, the rotating motor is started, the output shaft drives the adjusting worm to rotate, and then drives the adjusting worm gear and the rotating column connected therewith to rotate synchronously, so that the moving cavity frame installed in the rotating cavity plate rotates 90 degrees together with the cutting knife on the gear box, and the cutting knife on the gear box rotates 90 degrees together with the cutting knife on the gear box. The original vertical cutting posture is changed into a horizontal posture parallel to the surface of the OSB board. Then, the operator only needs to smoothly push the placing box, so that the OSB board can uniformly pass through the horizontally arranged rotating cutting knife in the feeding direction in the clamped state, thereby realizing the horizontal slicing of the board from top to bottom, without disassembling or overturning the board, avoiding the positioning inaccuracy, uneven layer thickness, cutting surface inclination and safety risk caused by traditional manual slicing.

[0012] Thirdly, the moving motor is started, the output shaft drives the moving screw to rotate accurately, and then drives the moving cavity frame connected therewith to move stably upward (or downward) under the guidance of the rotating cavity frame, and synchronously drives the gear box and the cutting knife to realize high-precision vertical position adjustment, so as to flexibly set the cutting height of the cutting knife in the thickness direction of the OSB board. This function enables the device to perform slicing of the OSB board with different total thicknesses (such as 9mm, 12mm, 18mm or 25mm) at any depth according to test requirements, for example, accurately cutting a specific area such as a surface layer of 2mm, a core layer of 5mm or a near bottom layer, to analyze the gradient distribution of density, bonding strength or shaving orientation.

[0013] Fourthly, when the OSB board needs to be cut into blocks, the self-adaptive clamping and fixing moving mechanism is used to firmly clamp the board to ensure no displacement during the whole process. Then, the electric push rod drives the rack plate to move backward under the guidance of the guide column, drives the cutting knife on the mounting frame to rotate 90° to the vertical cutting position, and then drives the telescopic cavity frame to move horizontally in the fixed cavity frame, cooperates with the operator to assist pushing the placing box, so that the OSB board moves left at a constant speed under the precise limiting of the horizontal guide frame and contacts the high-speed rotating cutting knife, to complete the first horizontal cut. After cutting, the adjusting motor is reversed to make the board retreat, and then the board is finely adjusted to the next preset cutting position along the vertical guide frame, and the feeding-cutting-retreating process is repeated to efficiently and equidistantly cut multiple parallel horizontal cuts. Then, the cutting knife is reset, the adjusting motor is actuated again to align the end of the cut horizontal cut with the cutting knife, and then the placing box is pushed longitudinally to complete the vertical cutting, so that the OSB board is finally cut into multiple regular block samples, which significantly improves the cutting position accuracy, sample size consistency and edge flatness.

[0014] Fifthly, during the cutting of the OSB board, the protective cover effectively encloses the cutting area, blocks the diffusion of wood chips to the surroundings, prevents dust pollution of the working environment and affects the respiratory health of the operators or adheres to the precise components of the equipment; at the same time, the dust suction shell can be connected to an external negative pressure dust suction system, which can instantly suck away the suspended fine shavings and dust at the moment of cutting, realizing source dust control; the larger debris that cannot be sucked away will naturally fall into the cutting box and be guided by the gravity of the two side inclined chip guide plates and smoothly slide into the collection box at the bottom; the operators can easily pull out the collection box from the cutting box after the work is completed, and clean or recycle the wood chips, which significantly improves the cleanliness of the work site.

[0019] As Figure 1 , 2As shown in Figures 3 and 6, the adaptive clamping and fixing moving mechanism includes multiple vertical guide frames 206 disposed inside the cutting box 101. A sliding plate 207 is slidably disposed between the outer arc surfaces of the multiple vertical guide frames 206. Multiple horizontal guide frames 208 are disposed on the upper side of the sliding plate 207.

[0020] By placing the OSB board to be cut on the placement box 201 and aligning the position to be cut with the cutting blade 305, the handwheel 212 is rotated to drive the clamping worm 204 to rotate, which in turn drives the clamping worm wheel 203 that meshes with it to rotate, so that the clamping fixing bracket 202 on the rotating column rotates towards each other and contacts the upper side of the OSB board, thereby achieving the fixing of OSB boards of different thicknesses and sizes.

[0021] Then, the cutting motor 303 is started, and the output shaft drives the cutting blade 305 on the rotating shaft to rotate.
