Description

Technical Field

[0001] This application relates to the field of physical and chemical performance testing of wood-based panels, and in particular to a grooving device for testing the peel force of wood-based panels. Background Technology

[0002] PVC engineered wood panels are made primarily from wood or non-wood plant fibers, processed into various material units, bonded with adhesives and other additives, and then glued to a plastic film to form boards or molded products. Peel resistance is a crucial performance characteristic of PVC engineered wood panels, reflecting the adhesion between the contact surfaces of the composite panels. GB / T 17657-2022 specifies that peel resistance requires a groove to be cut from one end of the specimen, with the groove extending to the point where it is bonded to the plastic film. Traditional grooving methods involve the tester measuring the distance from the specimen's end face with a ruler or calipers, marking the line with a marker, and then manually grooving with a cutting tool. This process is cumbersome. Furthermore, the pressure applied by the cutting tool during grooving depends on the tester's experience, making it difficult to guarantee the groove depth reaches the point where the plastic film is bonded, leading to measurement errors and even damage to the plastic film. Utility Model Content

[0003] This application provides a grooving device for testing the peel force of engineered wood panels. By integrating measuring tools and cutting tools, it solves the problems of cumbersome grooving operations and inaccurate control of cutting tool force.

[0004] This application provides a grooving device for testing the peel force of engineered wood panels. The device includes a grooving knife, a connecting rod, and a baffle. One end of the connecting rod is connected to the handle of the grooving knife, and the other end of the connecting rod is connected to the baffle.

[0005] The baffle has a position measuring element at one end near the artificial board, which is used to measure the bonding critical point between the plastic film and the artificial board substrate.

[0006] The tip of the grooving knife moves up and down in a direction perpendicular to the surface of the artificial board, aligning the tip of the grooving knife with the bonding critical point to determine the grooving depth.

[0007] In one feasible implementation, the baffle has a through hole, and the end of the connecting rod away from the grooving knife passes through the through hole and is slidably connected to the through hole to adjust the distance between the baffle and the grooving knife.

[0008] In one feasible implementation, one end of the connecting rod is provided with a slip ring, which is rotatably connected to the circumferential surface of the grooving cutter handle and slides along the axial direction of the grooving cutter handle. The slip ring is provided with an adjustment knob to lock the relative position of the grooving cutter and the connecting rod.

[0009] In one possible implementation, the connecting rod is provided with scale markings for measuring length.

[0010] In one feasible implementation, an infrared laser irradiation lamp is provided at the end of the baffle away from the connecting rod.

[0011] In one feasible implementation, the through hole is an oblong hole, and the connecting rod slides along the oblong hole.

[0012] In one feasible implementation, a pressure plate is provided at the end of the baffle away from the connecting rod.

[0013] In one feasible implementation, the end of the baffle away from the connecting rod has a slot, and the pressure plate is inserted into the slot.

[0014] This application provides a grooving device for peel force testing of engineered wood products. The device includes a grooving blade, a connecting rod, and a baffle. One end of the connecting rod is connected to the handle of the grooving blade, and the other end is connected to the baffle. In use, the length of the connecting rod can be used as a positioning reference to position the grooving blade. Alternatively, a graduated scale can be installed on the connecting rod for positioning the grooving blade. By integrating measuring tools and the blade, the tedious operation of repeatedly using rulers, calipers, and markers for positioning and marking is avoided, making the grooving operation more convenient. Furthermore, a laser irradiation lamp is installed at the bottom of the baffle. Utilizing the principle that the transparent plastic film transmits infrared laser light while the substrate does not, the groove depth is positioned, making the groove depth positioning more accurate. Further, a slip ring is provided at one end of the connecting rod, sliding along the axial direction of the grooving blade handle. An adjustment knob is also provided to lock the grooving blade. This design allows control of the distance between the grooving blade and the engineered wood product, avoiding reliance on the experience of the testing personnel, which could lead to uncontrolled grooving force and damage to the plastic film on the engineered wood product.

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0022] Reference Figure 1 As shown, Figure 1 This is a schematic diagram of a engineered wood panel component. The component includes an engineered wood panel substrate 4, a plastic film 5, and a groove 6 cut into the substrate 4. During the peel strength test, the plastic film is flipped 180° and peeled a certain length before being clamped in the testing machine fixture. The engineered wood panel specimen is stretched at both ends with a loading speed lower than 588 N / min, and the maximum load on the adhesion between the plastic film and the substrate is measured. During component fabrication, a groove needs to be cut from one end of the specimen, with the groove depth reaching the point where it will bond to the plastic film. In traditional grooving methods, the tester uses a ruler or calipers to measure the distance from the grooving position to the specimen end face, marks the line with a marker, and then uses a hand-held cutter to groove the panel. This operation is cumbersome. Furthermore, the pressure applied by the cutter during grooving depends on the tester's experience, making it difficult to guarantee the groove depth reaches the point where the plastic film is bonded, which can easily damage the plastic film. This application provides an engineered wood panel grooving device that integrates measuring tools and a cutter, solving the problems of cumbersome operation and inaccurate control of cutter pressure during grooving.

[0023] Reference Figure 2 As shown, Figure 2 This is a schematic diagram of a grooving device for testing the peel force of engineered wood products according to an embodiment of this application. The engineered wood grooving device includes a grooving blade 1, a connecting rod 2, and a baffle 3. One end of the connecting rod 2 is connected to the handle of the grooving blade 1, and the other end of the connecting rod 2 is connected to the baffle 3.

[0024] When using this device for grooving, the grooving blade 1 can be positioned by setting the length of the connecting rod 2. In one implementation, both the grooving blade 1 and the baffle 3 are fixedly connected to the connecting rod 2. In this case, the distance between the grooving blade 1 and the edge of the workpiece is determined by the length of the connecting rod 2. That is, the length of the connecting rod 2 is fixed, and the distance between the tip of the grooving blade 1 and the side of the baffle 3 is fixed. When this distance meets the grooving position requirements, grooving can be performed without additional measuring tools. When grooving different batches of workpieces using this device, the grooving position can be determined simply by aligning the edge of the workpiece with the side of the baffle 3. Furthermore, when both the grooving blade 1 and the baffle 3 are fixedly connected to the connecting rod 2, the height difference between the lower surface of the baffle 3 and the tip of the grooving blade 1 is determined based on the overall thickness of the engineered wood panel and the overall thickness of the engineered wood panel substrate to achieve precise control of the grooving depth. This device can meet the grooving requirements of engineered wood panels of the same thickness but different batches, thereby improving the efficiency of peel force testing.

[0025] As an example, refer to Figure 1 and Figure 2 As shown, during the grooving operation, the left edge of the engineered wood sample is placed against the side of the baffle 3 near the grooving blade 1. At this time, the tip of the grooving blade 1 is located at the groove 6. Moving the grooving device, the grooving blade 1 slides smoothly along the surface of the engineered wood substrate, thus successfully completing the grooving work. During the grooving process, the side of the baffle 3 near the grooving blade 1 is always in contact with the edge of the engineered wood sample, thereby ensuring the straightness of the groove 6 and improving the accuracy and efficiency of the grooving work.

[0026] Continue to refer to Figure 2 As shown, the end of the baffle 3 closest to the engineered wood panel has a position measuring element 32, which is used to measure the bonding critical point between the plastic film 5 and the engineered wood panel substrate 4. The tip of the grooving knife 1 moves up and down in a direction perpendicular to the surface of the engineered wood panel, aligning the tip of the grooving knife 1 with the bonding critical point to determine the grooving depth. In some implementations, the baffle 3 has a through hole 31, and the end of the connecting rod 2 furthest from the grooving knife 1 passes through the through hole 31 and is slidably connected to it. In this case, the distance between the baffle 3 and the grooving knife 1 can be adjusted. In practical applications, the relative position of the grooving knife 1 and the baffle 3 can be flexibly adjusted according to different processing materials, grooving depth requirements, or other process requirements, thereby precisely controlling the working range and depth of the grooving knife 1. This not only improves the processing accuracy and efficiency but also greatly enhances the adaptability and flexibility of the equipment.

[0027] In some other implementations, one end of the connecting rod 2 is provided with a slip ring 21. The slip ring 21 is rotatably connected to the circumferential surface of the grooving cutter 1 handle and slides along the axial direction of the grooving cutter 1 handle, realizing flexible adjustment between the connecting rod 2 and the grooving cutter 1. The slip ring 21 is provided with an adjustment knob 211. When the adjustment knob 211 is rotated, the end of the adjustment knob 211 near the grooving cutter 1 exerts a moderate pressure on the grooving cutter 1 handle, thereby fixing the two together and effectively locking the relative position of the grooving cutter 1 and the connecting rod 2.

[0028] At this point, by setting the slip ring 21, the height of the grooving knife 1 can be adjusted along the direction perpendicular to the surface of the engineered wood panel, thereby controlling the grooving depth and enabling grooving of engineered wood panel samples of different thicknesses. Grooving can be efficiently completed for various specifications of panels. In other implementations, without using the slip ring 21, the grooving knife 1 can be set as a telescopic tool, meaning the distance between the tip and the handle of the grooving knife 1 can be adjusted, thus also achieving adjustment of the grooving depth.

[0029] In some implementations, the connecting rod 2 is equipped with scale markings for measuring length. These markings cover the effective length range of the connecting rod 2. When performing grooving operations, the operator can fully utilize these markings and, through simple visual comparison, intuitively and accurately measure the current position of the grooving tool 1, thus improving operational efficiency. For example, referring to... Figure 1 As shown, when the distance between the groove 6 and the left edge of the artificial board is required to be 10mm, the end closest to the baffle 3 is used as the starting point to observe the scale mark. When the scale mark reaches 10mm, move the grooving knife 1 to the position corresponding to that scale mark to complete the measurement work.

[0030] In some implementations, the end of the baffle 3 closest to the artificial board has a position measuring element 32, which is an infrared laser irradiation lamp. (See reference...) Figure 1As shown, the infrared laser irradiation lamp 32 illuminates the side of the artificial substrate. The grooving depth is determined by utilizing the principle that the transparent plastic film transmits infrared laser light while the substrate does not. Specifically, when the infrared laser light shines on the plastic film 5, the light is transmitted. Then, the baffle 3 moves closer to the artificial substrate 4, causing the infrared laser irradiation lamp to move towards it. When the light is precisely no longer transmitted, the position of the infrared laser irradiation lamp is the intersection of the plastic film 5 and the artificial substrate 4. After determining this position, the relative positions of the grooving blade 1 and the slip ring 2 are adjusted so that the tip of the grooving blade 1 is precisely aligned with this position, thus ensuring that the grooving depth reaches exactly the bonding point between the artificial substrate 4 and the plastic film 5. Compared to traditional methods of determining grooving depth, using an infrared laser irradiation lamp allows for more precise control of the grooving depth and avoids the waste of materials caused by using multiple test pieces during the grooving depth determination process. In some other implementations, the position measuring component 32 can also be an optical position sensor, which uses the different degrees of light reflection in different materials to determine the critical point of adhesion.

[0031] In some implementations, after determining the grooving depth, the connecting rod 2 is rotated, causing the baffle 3 to rotate 90° and its length adjusted (the baffle 3 can be set as a telescopic baffle). While maintaining the grooving depth, the length of the baffle 3 is shortened, allowing the light emitted by the infrared laser irradiation lamp 32 to illuminate the surface of the engineered wood substrate, forming a light spot. The grooving blade 1 moves towards this light spot to perform the grooving operation. As the grooving blade 1 moves, the light spot formed by the infrared laser irradiation lamp also moves continuously, always guiding the grooving blade 1 and providing an effective grooving path. Specifically, as described above, the slip ring 21 is rotatably connected to the circumferential surface of the grooving cutter 1. After determining the starting position of the groove 6 (the method of determining this position can be based on the length of the connecting rod 2 or the scale markings, which will not be elaborated here), the grooving cutter 1 is positioned here and remains stationary. When the slip ring 21 is rotated, the baffle 3 rotates with the rotation of the slip ring 21. When the baffle 3 rotates 90°, the light emitted by the infrared laser irradiation lamp 32 illuminates the artificial board substrate to form a light spot. The line connecting the light spot and the tip of the grooving cutter 1 should coincide with the position of the groove 6. The light spot guides the travel direction of the tip of the grooving cutter 1, so that the groove 6 remains straight.

[0032] In some implementations, the width of groove 6 is 1mm-3mm, and grooving can be completed simply by selecting a blade of the appropriate thickness.

[0033] Reference Figure 3 As shown, Figure 3This is a schematic diagram of another grooving device for testing the peel force of engineered wood panels provided in this embodiment. In some implementations, the through hole 31 is an oblong hole, and the connecting rod 2 slides along the oblong hole. In this implementation, the position of the baffle 3 remains unchanged, and the grooving position is still located by the length of the connecting rod 2 or the scale on the connecting rod 2. The grooving depth is controlled by the relative position of the grooving cutter 1 and the slip ring 21.

[0034] In some implementations, a pressure plate 33 is provided at the end of the baffle 3 away from the connecting rod 2. In this case, the pressure plate 33 can apply a certain pressure to the engineered wood panel to prevent it from moving during the grooving process. Furthermore, the width of the pressure plate 33 can be used to position the grooving knife 1. Specifically, the edge of the pressure plate 33 near the baffle 3 is close to the side of the baffle 3 near the grooving knife 1 (at this time, the edge of the engineered wood panel specimen near the baffle 3 is also close to the side of the baffle 3 near the grooving knife 1), and the other edge parallel to this edge is close to the tip of the grooving knife 1. The grooving position can be determined by adjusting the width of the pressure plate 33. In some implementations, a slot 34 is provided at the end of the baffle 3 away from the connecting rod 2, and the pressure plate 33 is inserted into the slot 34. This insertion connection facilitates the replacement of the pressure plate 33. By replacing pressure plates 33 of different widths, the grooving position can be adjusted to meet the grooving requirements of engineered wood panels of various specifications.

[0035] This application provides a grooving device for engineered wood panels, which mainly includes a grooving blade, a connecting rod, and a baffle. The device integrates measuring and cutting tools for grooving through a simple structural design. By setting the length of the connecting rod, the distance between the grooving blade and the edge of the workpiece can be precisely controlled. When both the grooving blade and the baffle are fixedly connected to the connecting rod, the grooving position can be quickly located without additional measuring tools, improving work efficiency. The connecting rod and the baffle are slidably connected, allowing adjustment of their relative positions according to the processing material and grooving depth requirements, enhancing the adaptability and flexibility of the equipment. A slip ring is provided at one end of the connecting rod, which is rotatably and slidably connected to the grooving blade handle. The relative positions of the two can be fixed by adjusting a knob, thereby precisely controlling the grooving depth, suitable for engineered wood panels of different thicknesses. Furthermore, a scale marking can be provided on the connecting rod for easy and intuitive measurement of the grooving blade position. An infrared laser irradiation lamp can also be optionally installed at one end of the baffle, providing accurate movement path guidance for the grooving blade while precisely positioning the grooving depth. A pressure plate can be optionally installed at the end of the baffle away from the connecting rod to apply pressure to the engineered wood to prevent movement. At the same time, the width of the pressure plate can also be used as a reference for the grooving position. By changing the pressure plate of different widths, the grooving requirements of more specifications of engineered wood can be met.
