Description

Technical Field

[0001] The utility model relates to the field of detecting the bonding strength of wood-based panels, and particularly to a device for detecting the bonding strength of adhesives for wood-based panels. Background Technique

[0002] Wood-based panels are made of wood or other non-wood plants as raw materials. After being mechanically processed into various unit materials, they are glued with or without adhesives and other additives to form boards or molded products. They mainly include three categories of products: plywood, particle (chip) boards, and fiberboards, and their extended products and deep-processed products reach more than a hundred kinds.

[0003] At present, after the wood-based panels are bonded with adhesives, it is necessary to detect their strength to determine whether the bonding performance meets the standards. The current detection method is through two cylinders, with push plates fixed at the ends of the cylinders, and the push plates are pressed against the sides of the wood-based panels. For example, a device for detecting the bonding strength of adhesives for wood-based panels disclosed in the patent with the application number 201721204034.8. In the process of this detection method, due to the pressure on both sides, the wood-based panels are prone to breakage. At the same time, when detecting the strength of the adhesive, it is necessary to be boiled in boiling water at a high temperature to ensure the bonding strength of the adhesive in various environments. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a device for detecting the bonding strength of adhesives for wood-based panels, so as to solve the technical problem that the wood-based panels are prone to breakage risks during the detection process.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for detecting the bonding strength of adhesives for wood-based panels, including a device main body. On one side of the device main body, a boiling box is installed. The top of the boiling box is provided with a top cover that can be opened movably. Inside the boiling box, a boiling cavity is opened. Inside the boiling cavity, a filter partition is installed. Below the filter partition, a heating rod is installed. On one side of the top of the boiling box, a mesh bag is opened.

[0006] By adopting the above technical solution, the boiling box provides conditions for testing the performance of wood-based panel adhesives in high-temperature and high-humidity environments. This environmental simulation can ensure that the performance of the adhesive in actual use is accurately evaluated.

[0007] Furthermore, the mesh bag is made of stainless steel wire mesh. The inner part of the mesh bag slopes downward on the side away from the top cover, and a handle is fixed on the top cover.

[0008] By adopting the above technical solution, the mesh bag made of stainless steel wire mesh has excellent corrosion resistance and durability. In the long-term boiling and humid environment, it can maintain stable performance, is not easy to rust or damage, thus extending the service life of the device.

[0009] Furthermore, a protective door is connected to the outer surface of the device body through a hinge, and a stainless-steel glass and a handle are respectively installed on the outer surface of the protective door.

[0010] By adopting the above technical solution, the protective door can provide additional safety protection during the test. When performing strength detection, closing the protective door can prevent the wood-based panel from accidentally popping out or splashing during the stretching process, thus protecting the safety of the operator.

[0011] Furthermore, a cylinder is installed inside the device body. A piston rod is installed at the output end of the cylinder. A U-shaped frame is fixed at the end of the piston rod. Two mirror-image lead screws are threadedly connected to the U-shaped frame. A disc is fixed at the outer end of the lead screw. By simply rotating the disc, the distance between the clamping plates can be adjusted without complex tools or operation steps. The inner end of the lead screw is connected to a clamping plate through a rotating shaft.

[0012] By adopting the above technical solution, the cylinder and its piston rod installed inside the device body provide stable and precise tensile force control. By adjusting the stroke and speed of the cylinder, the tensile or compressive force on the wood-based panel can be precisely controlled, thus ensuring the accuracy and reliability of the test.

[0013] Furthermore, there are two groups of cylinders, and the two groups of cylinders are arranged in a mirror image.

[0014] By adopting the above technical solution, the mirror-image arrangement means that the positions of the two groups of cylinders in the device are symmetrical with respect to a certain center point or axis, thus ensuring that the forces applied during the test are uniform and symmetrical.

[0015] Furthermore, there are two groups of clamps, and a wood-based panel is clamped between the two groups of clamps. The wood-based panel is composed of a first wood-based panel and a second wood-based panel.

[0016] By adopting the above technical solution, it can be ensured that the wood-based panel does not displace or slide during the test, thus accurately evaluating the bonding strength of the adhesive and improving the accuracy and reliability of the test.

[0017] Furthermore, an operation panel is installed on one side of the device body, and the operation panel is electrically connected to the heating rod and the cylinder respectively.

[0018] By adopting the above technical solution, the operator can easily adjust parameters such as the temperature of the heating rod and the tensile or pressure force of the cylinder. This intuitive interface and simple operation method reduce the skill requirements for the operator and reduce the possibility of misoperation.

[0019] In summary, the present utility model mainly has the following beneficial effects:

[0020] The utility model is provided with a boiling box, which is provided with a boiling cavity, a filter partition plate and a heating rod inside. A net pocket is arranged on the side of the boiling box. Before detecting the wood-based panel, the wood-based panel is placed in the boiling cavity, water is added, and it is boiled through the heating rod, so that the wood-based panel is in a high-temperature water body. Then the wood-based panel is taken out and placed in the net pocket to dry. After that, the two ends of the wood-based panel are respectively clamped by two jigs, and the adhesive strength of the wood-based panel is detected.

[0021] The utility model is provided with a protective door, which can protect the wood-based panel, avoid the wood-based panel from cracking and splashing during the pulling process, and can limit the range of the wood-based panel, improving safety on the one hand and being beneficial to later cleaning on the other hand.

[0030] The following describes the embodiments of the present utility model according to its overall structure. Embodiment

[0031] An adhesive strength detection device for wood-based panel adhesives, as Figures 1 - 4 shown, includes a device main body 1. A boiling box 3 is installed on one side of the device main body 1. The top of the boiling box 3 is provided with a lid 31 that can be opened movably. A boiling cavity 34 is opened inside the boiling box 3. A filter partition 35 is installed inside the boiling cavity 34. A heating rod 36 is provided below the filter partition 35. A mesh bag 33 is opened on one side of the top of the boiling box 3. The boiling box 3 provides conditions for testing the performance of wood-based panel adhesives in a high-temperature and high-humidity environment. This environmental simulation can ensure that the performance of the adhesive in actual use is accurately evaluated. The filter partition 35 provided inside the boiling cavity 34 can prevent the wood-based panel from directly contacting the heating rod 36, thereby preventing damage to the wood-based panel during the heating process and ensuring the accuracy of the test. The setting of the mesh bag 33 enables users to conveniently take out and dry the wood-based panel after boiling.

[0032] Please refer to Figure 1, the mesh bag 33 is made of stainless steel wire mesh. The inner part of the mesh bag 33 slopes downward on the side away from the top cover 31. A handle 32 is fixed on the top cover 31. The mesh bag 33 made of stainless steel wire mesh has excellent corrosion resistance and durability. In a long-term boiling and humid environment, it can maintain stable performance, is not easy to rust or damage, thus extending the service life of the device. The stainless steel wire mesh has good strength and toughness, can bear a certain weight of artificial board, and ensures that it will not break or deform during the test. The inner part of the mesh bag 33 slopes downward on the side away from the top cover 31, which helps to drain excess water during the drying process, can speed up the drying speed, reduce the waiting time, and improve the test efficiency.

[0033] Please refer to Figure 2 , a cylinder 4 is installed inside the device body 1. A piston rod 41 is installed at the output end of the cylinder 4. The end of the piston rod 41 is fixed with a U-shaped frame 51. Two mirror-image screw rods 55 are threadedly connected to the U-shaped frame 51. A disc 52 is fixed at the outer end of the screw rod 55. By simply rotating the disc 52, the distance between the clamping plates 54 can be adjusted without complex tools or operation steps. The inner end of the screw rod 55 is connected to a clamping plate 54 through a rotating shaft 53. The cylinder 4 and its piston rod 41 installed inside the device body 1 provide stable and precise tensile force control. By adjusting the stroke and speed of the cylinder 4, the tensile or compressive force on the artificial board can be precisely controlled, thus ensuring the accuracy and reliability of the test. The design of the clamping plates 54 connected to the U-shaped frame 51 through the screw rods 55 allows the operator to flexibly adjust the clamping position and clamping force according to the size and shape of the artificial board. By rotating the disc 52 to drive the rotation of the screw rod 55, the distance between the clamping plates 54 can be adjusted to adapt to artificial boards of different specifications.

[0034] Please refer to Figure 2 , there are two groups of cylinders 4, and the two groups of cylinders 4 are arranged in a mirror image. Mirror image arrangement means that the positions of the two groups of cylinders in the device are symmetric with respect to a certain center point or axis, thus ensuring that the forces applied during the test are uniform and symmetric.

[0035] Please refer to Figure 3 and Figure 4 , there are two groups of fixtures 5, and an artificial board 6 is clamped between the two groups of fixtures 5. The artificial board 6 is composed of a first artificial board 61 and a second artificial board 62, which can ensure that the artificial board will not displace or slide during the test, thus accurately evaluating the bonding strength of the adhesive and improving the accuracy and reliability of the test. Embodiment

[0036] Please refer to Figure 1, a protective door 2 is connected to the outer surface of the device main body 1 through a hinge. A stainless-steel glass 21 and a handle 22 are respectively installed on the outer surface of the protective door 2. The protective door 2 can provide additional safety protection during the test. When performing strength detection, closing the protective door 2 can prevent the artificial board from accidentally popping out or splashing during the stretching process, thus protecting the safety of the operator. The stainless-steel glass 21 installed on the outer surface of the protective door 2 allows the operator to directly observe the test situation inside the device without opening the protective door, enabling the operator to monitor the test process in real time and ensuring the accuracy and reliability of the test.

[0037] Please refer to Figure 1 , an operation panel is installed on one side of the device main body 1. The operation panel is electrically connected to the heating rod 36 and the cylinder 4 respectively. The operator can easily adjust parameters such as the temperature of the heating rod 36 and the pulling force or pressure of the cylinder 4. This intuitive interface and simple operation method reduce the skill requirements for the operator and reduce the possibility of misoperation. The electrical connection ensures the precise control of the operation panel over the heating rod 36 and the cylinder 4. Whether it is the fine adjustment of temperature or the precise application of force, it can be quickly achieved through the operation panel, thereby improving the accuracy and reliability of the test.
