Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plywood, in particular to a plywood compressive testing device. Background Art
[0002] Plywood is a three-layer or multi-layer plate material made by slicing wood segments into veneers or planing wooden squares into thin woods and then gluing them with adhesives. It is usually made of an odd number of veneers, and the fiber directions of adjacent veneers are perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major types of wood-based panels. It can also be used as a building material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers is usually assembled and glued with the grain directions of adjacent layers perpendicular to each other. Usually, the surface veneer and the inner veneer are symmetrically arranged on both sides of the core layer or the board core. The board blank formed by arranging the veneers coated with glue in a criss-cross pattern along the grain direction is pressed under heated or unheated conditions. The number of layers is generally odd, and a few are even. The physical and mechanical properties in the longitudinal and transverse directions have small differences. Commonly used types of plywood include three-ply board, five-ply board, etc. Plywood can improve the utilization rate of wood and is a main way to save wood.
[0003] During the production process of plywood, before storage after production, it is necessary to check the overall integrity and whether there are damages on the appearance, but the quality of the board cannot be detected. At the same time, the existing methods for detecting quality are usually relatively violent, and the control of the force is not precise enough. During the detection process, the degree of damage to the plywood cannot be controlled. Therefore, we propose a plywood compressive testing device. Content of the Utility Model

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A plywood compressive testing device includes a support table. Fixed frames are fixedly installed at positions near the left and right sides above the support table. A clamping frame is movably sleeved inside the fixed frames. The bottom surfaces of the two clamping frames are fixedly connected to a co-location lifting plate. A first telescopic column is fixedly installed on the bottom surface of the support table, and a limiting block is fixedly connected to the outer side of the output shaft of the first telescopic column.
[0006] Optionally, a support rod is fixedly supported above the support table. A rotating sleeve is movably sleeved outside the support rod. A driving motor is supported on the upper surface of the left fixed frame, and a rotating shaft is fixedly connected to the outer end of the output shaft of the driving motor.
[0007] Optionally, a second telescopic column is supported above the two fixed frames, and a support bar is fixedly connected to the outer side of the output shaft of the second telescopic column.
[0008] Optionally, the clamping frame extends downward to below the support platform, the co-location lifting plate is located below the support platform, and the co-location lifting plate is located between two limit blocks.
[0009] Optionally, the vertical section of the limit block is a right-angle trapezoid, and the hypotenuse of the limit block and the outer side of the same-position lifting plate are in contact with each other.
[0010] Optionally, the rotating shaft is located inside the rotating sleeve, the axis of the rotating shaft and the axis of the support rod are located on the same horizontal line, and the axis of the rotating sleeve is located outside the axis of the support rod.
[0011] The utility model provides a plywood compression testing device, which has the following beneficial effects:
[0012] 1. The plywood compression test equipment has a fixed frame supported on the top of the support platform, and a clamping frame is movably mounted on the inner side of the support platform and the fixed frame. During use, the same-position lifting plate and the first telescopic column cooperate with the limit block to complete the control of the position of the clamping frame, thereby lifting the plywood to be tested, and facilitating the quality inspection of the twisted board. After the inspection is completed, the plywood can be directly pushed backwards to facilitate the replacement of new plywood for inspection.
[0013] 2. The plywood compression test equipment supports the support rod above the support platform, so that the outer movable sleeve of the support rod is equipped with a rotating sleeve with different axes.

Detailed implementation mode
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a plywood compressive strength testing device, including a support table 1. Fixed frames 2 are fixedly installed above the support table 1 near the left and right sides. A second telescopic column 7 is supported above the two fixed frames 2. A support bar 8 is fixedly connected to the outer side of the output shaft of the second telescopic column 7. The second telescopic column 7 and the support bar 8 are arranged to play a role in supporting and limiting the rotating sleeve 10 during use, which can prevent the rotating sleeve 10 from falling and causing damage to the output shaft of the driving motor 12, playing a protective role and improving the safety of the device. A clamping frame 3 is movably sleeved inside the fixed frame 2. The clamping frame 3 extends downward below the support table 1. The same-position lifting plate 4 is located below the support table 1 and between the two limit blocks 6. The fixed frame 2 and the clamping frame 3 can play a role in clamping the plywood. At the same time, the support table 1 can support the plywood. The same-position lifting plate 4 is arranged to support the two clamping frames 3 to move upward in the same position, ensuring the stable transportation of the two clamping frames 3 and facilitating the use of the device. The bottom surfaces of the two clamping frames 3 are fixedly connected to the same-position lifting plate 4. The vertical section of the limit block 6 is in the shape of a right trapezoid, and the hypotenuse of the limit block 6 is in mutual contact with the outer side of the same-position lifting plate 4. Control the output shaft of the first telescopic column 5 to extend, so that the output shaft of the first telescopic column 5 pushes the limit block 6 to move. During the movement of the limit block 6, the same-position lifting plate 4 is pushed to move upward. During the movement of the same-position lifting plate 4, the clamping frame 3 is pushed to move upward. The first telescopic column 5 is fixedly installed on the bottom surface of the support table 1, and a limit block 6 is fixedly connected to the outer side of the output shaft of the first telescopic column 5.
[0022] A support rod 9 is fixedly supported above the support table 1. The rotating shaft 11 is located inside the rotating sleeve 10. The axes of the rotating shaft 11 and the support rod 9 are on the same horizontal line. The axis of the rotating sleeve 10 is located outside the axis of the support rod 9. Control the output shaft of the driving motor 12 to drive the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the rotating sleeve 10 to rotate during the rotation process. The compressive deformation test of the plywood is completed when the rotating sleeve 10 rotates. The support rod 9 can limit the movement range of the rotating sleeve 10, thereby limiting the amount of downward pressure of the rotating sleeve 10, stably controlling the magnitude of the pressure, and facilitating the use of the device. The rotating sleeve 10 is movably sleeved outside the support rod 9. The driving motor 12 is supported on the left fixed frame 2, and the outer end of the output shaft of the driving motor 12 is fixedly connected to the rotating shaft 11.
[0023] In summary, for the plywood compressive testing equipment, during use, first send the plywood from the front side of the support table 1 into the interior of the support table 1. Then, after the plywood is completely placed between the fixing frame 2 and the clamping frame 3, control the output shaft of the first telescopic column 5 to extend, so that the output shaft of the first telescopic column 5 pushes the limiting block 6 to move. During the movement of the limiting block 6, it pushes the same-position lifting plate 4 to move upward. During the movement of the same-position lifting plate 4, it pushes the clamping frame 3 to move upward. With the cooperation of the two clamping frames 3, the bottom surface of the plywood is separated from the top surface of the support table 1. Subsequently, the positioning of the plywood is completed through the cooperation of the fixing frame 2 and the clamping frame 3. Then, control the output shaft of the second telescopic column 7 to drive the support bar 8 to move outward, so that the support bar 8 moves away from the rotating sleeve 10. Control the output shaft of the driving motor 12 to drive the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, it drives the rotating sleeve 10 to rotate. When the rotating sleeve 10 rotates, the test of the compressive deformation of the plywood is completed. That's it.
