Description
Technical Field
[0001] This utility model relates to the field of composite board testing technology, and in particular to a high-efficiency density composite board bending strength testing device. Background Technology
[0002] High-density composite board is a board made of multiple materials through high temperature and high pressure. It has the characteristics of high strength, high density, waterproof and fireproof. Its material composition mainly includes wood fiber (or other fiber materials), resin and additives. Wood fiber provides the basic structure and strength of the board, resin plays a bonding and reinforcing role, and additives are used to improve the waterproof and fireproof properties of the board. A testing device is required when conducting bending strength testing on high-density composite board.
[0003] The current testing equipment, during installation and use, has gradually revealed the following shortcomings:
[0004] (1) The distance between the support frames for placing the test sample in most testing devices is fixed, and only composite plates of a specific length can be tested. At the same time, there are no limiting devices on the support frames, so the position of the sample plate may deviate during the test, which will affect the test results of the composite plate and make the test inaccurate.
[0005] (2) The composite board will break outward after being bent. The broken material will be scattered everywhere, which is very inconvenient for the staff to clean up later. It also wastes a lot of time and reduces work efficiency.
[0006] (3) When the composite board is subjected to external force, it will bend and break outward, which will make it impossible to guarantee the safety of the workers. Utility Model Content
[0007] In order to overcome the defects of the prior art as mentioned above, the inventors of this utility model have conducted in-depth research and, after a great deal of creative work, have completed this utility model.
[0008] Specifically, the technical problem to be solved by this utility model is to provide a high-efficiency density composite board bending strength testing device to solve the problem that most current testing devices have a fixed distance between the support frames for placing test samples, which can only test composite boards of a specific length. At the same time, the support frames are not equipped with limiting devices, and the position of the sample board may deviate during the test, which will affect the test results of the composite board and make the test inaccurate.
[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0010] A high-efficiency density composite board bending strength testing device includes a test chamber, a hydraulic cylinder at the top of the test chamber, a telescopic shaft connected to the output end of the hydraulic cylinder, a pressure block at the bottom end of the telescopic shaft, a sample adjustment component at one end of the test chamber, a cleaning component inside the test chamber, and a protective component on one side of the test chamber.
[0011] The sample adjustment assembly includes a motor, the output end of which is connected to a bidirectional threaded rod. A slide table is symmetrically provided on the bidirectional threaded rod. A slide groove is symmetrically opened on the top of the slide table. A slide rod is provided inside the slide groove. A limiting plate is provided on the slide rod. A spring is sleeved on the outer surface of the slide rod. The spring is located between the limiting plate and the slide table.
[0012] As an improved technical solution, the test chamber has a T-slot inside, the bidirectional threaded rod is located inside the T-slot, and the slide is slidably connected to the T-slot.
[0013] As an improved technical solution, the motor is located at one end of the test box, the bidirectional threaded rod is threadedly connected to the slide table, the slide rod is slidably connected to the limiting plate, and the limiting plate is slidably connected to the slide groove.
[0014] As an improved technical solution, the cleaning component includes a collection chamber located at the bottom of the test chamber. An electric push rod is provided on the other side of the test chamber. The output end of the electric push rod is connected to a telescopic shaft II, and a push plate is provided at one end of the telescopic shaft II.
[0015] As an improved technical solution, the push plate is provided with sliders at both ends, the inner wall of the test chamber is symmetrically provided with guide grooves, the sliders are slidably connected with the guide grooves, and the bottom of the test chamber is provided with a cleaning port.
[0016] As an improved technical solution, the protective component includes observation doors, two of which are symmetrically arranged on one side of the test chamber, and a handle is provided on one side of each observation door.
[0017] After adopting the above technical solution, the beneficial effects of this utility model are:
[0018] 1. This utility model uses a motor to drive a bidirectional threaded rod to rotate in both directions. The bidirectional threaded rod drives two slides to move in opposite directions along a T-slot, thereby changing the distance between the two slides. This allows for the testing of composite plates of different lengths. Two limiting plates limit the composite plate, ensuring the test position of the composite plate and preventing deviation of the sample plate position during testing. This does not affect the test results of the composite plate and makes the test more accurate.
[0019] 2. This utility model collects waste material from composite boards through a collection chamber. An electric push rod drives a telescopic shaft two to move, which in turn drives a push plate to slide along a guide groove via a slider. The push plate pushes the waste material to the cleaning port, facilitating subsequent cleaning by staff, reducing cleaning difficulty, saving a lot of time, and improving work efficiency.
[0020] 3. This utility model facilitates observation through the observation door. The test chamber and the observation door form a closed space, which can prevent the composite board from breaking outward after being bent, thus better protecting the safety of the staff. Attached Figure Description

[0032] like Figure 1 and Figure 4 As shown in the figure, this embodiment provides a high-efficiency density composite board bending strength testing device, including a test chamber 1, a hydraulic cylinder 2 at the top of the test chamber 1, a telescopic shaft 3 connected to the output end of the hydraulic cylinder 2, a pressure block 4 at the bottom end of the telescopic shaft 3, a sample adjustment component 5 at one end of the test chamber 1, a cleaning component 6 inside the test chamber 1, and a protective component 7 on one side of the test chamber 1.
[0033] The sample adjustment assembly 5 includes a motor 51, the output end of which is connected to a bidirectional threaded rod 52 with opposite threads. Symmetrically arranged slides 53 are mounted on the bidirectional threaded rod 52, and symmetrically arranged grooves 54 are formed on the top of each slide 53. A slide rod 55 is located inside the groove 54, and a limiting plate 56 is mounted on the slide rod 55. A spring 57 is fitted onto the outer surface of the slide rod 55, positioned between the limiting plate 56 and the slide 53. The motor 51 rotates the bidirectional threaded rod 52 by rotating it in both directions, causing the two slides 53 to move in opposite directions along the T-slot 58, thus changing the distance between them. This allows for testing of composite plates of different lengths. The two limiting plates 56 limit the position of the composite plate, ensuring its testing position and preventing deviation of the sample plate during testing.
[0034] The test chamber 1 has a T-slot 58 inside, and a bidirectional threaded rod 52 is located inside the T-slot 58. The slide table 53 is slidably connected to the T-slot 58, and the T-slot 58 guides the slide table 53.
[0035] The motor 51 is located at one end of the test box 1. The bidirectional threaded rod 52 is threadedly connected to the slide table 53. The slide rod 55 is slidably connected to the limiting plate 56. The limiting plate 56 is slidably connected to the slide groove 54. The slide groove 54 guides the limiting plate 56.
[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning component 6 includes a collection chamber 61 located at the bottom of the test chamber 1. An electric push rod 62 is provided on the other side of the test chamber 1. The output end of the electric push rod 62 is connected to a telescopic shaft 63. One end of the telescopic shaft 63 is provided with a push plate 64. The electric push rod 62 drives the telescopic shaft 63 to move, and the telescopic shaft 63 drives the push plate 64 to slide along the guide groove 66 via a slider 65. The push plate 64 pushes the waste material to the cleaning port 67, which is convenient for subsequent cleaning by the staff.
[0037] The push plate 64 has sliders 65 at both ends. The inner wall of the test chamber 1 is symmetrically provided with guide grooves 66. The sliders 65 are slidably connected to the guide grooves 66. The bottom of the test chamber 1 is provided with a cleaning port 67, which guides the sliders 65 through the guide grooves 66.
[0038] like Figure 1 As shown, the protective component 7 includes an observation door 71, which is connected to the test chamber 1 by a hinge. Two observation doors 71 are symmetrically arranged on one side of the test chamber 1. A handle 72 is provided on one side of the observation door 71. The test chamber 1 and the observation door 71 form a closed space, which can prevent the composite board from breaking out when it is bent.
[0039] In use, the operator first opens the two symmetrical observation doors 71 using handle 72. Depending on the length of the composite plate, the motor 51 is started. The motor 51 rotates in both directions, driving the bidirectional threaded rod 52 to rotate. The bidirectional threaded rod 52 drives the two slides 53 to move in opposite directions along the T-slot 58, thus changing the distance between the two slides 53. This allows for testing of composite plates of different lengths. Next, the limiting plate 56 is pulled. The limiting plate 56 slides along the slide rod 55, compressing the spring 57 and generating tension. The composite plate is then placed between the two limiting plates 56. The tension of the spring 57 clamps and compresses both sides of the composite plate. The two limiting plates 56 limit the composite plate's position, ensuring the testing position is correct and preventing deviation of the sample plate during testing. This prevents deviation from the test results and makes the test more accurate. Finally, the two observation doors 71 are closed. Hydraulic cylinder 2 is activated, which drives pressure block 4 downward via telescopic shaft 3. Pressure block 4 compresses the composite board until it breaks, thus obtaining the corresponding bending strength test value. The test chamber 1 is observed through observation door 71. After the composite board breaks, waste material will be ejected. The test chamber 1 and observation door 71 form a closed space, which can block the ejection of composite board material when it is bent outward, thus better ensuring the safety of the staff. Finally, the waste material of composite board is collected through collection chamber 61. Electric push rod 62 is activated, which drives telescopic shaft 63 to move. Telescopic shaft 63 drives push plate 64 to slide along guide groove 66 via slider 65. Push plate 64 pushes the waste material to cleaning port 67, which is convenient for subsequent cleaning by staff, reduces the cleaning difficulty, saves a lot of time, and improves work efficiency.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
