Description

Technical Field

[0001] This utility model mainly relates to the field of performance testing technology for wooden pallets, and specifically to a performance testing device for the production of wooden pallets. Background Technology

[0002] Wooden pallets are widely used in logistics and transportation industries, and their performance directly affects the safety and reliability of cargo transportation. During the production process of wooden pallets, multiple indicators, such as load-bearing capacity, compressive strength, and impact resistance, need to be tested.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: Chinese Patent Publication No. CN222545093U discloses a performance testing device for wooden pallet production, comprising a platform with support plates on both the left and right sides of the bottom. This device, by placing a wooden pallet on top of the platform between two first clamping plates and two second clamping plates, then activating a servo motor and second hydraulic cylinders on both sides to clamp and fix the pallet, preventing displacement and shaking during testing and thus avoiding any impact on the test results. Furthermore, by activating a dual-axis servo motor, a rectangular cover is moved downwards until its bottom is flush with the top of the platform, thus securing the rectangular cover to the outside of the entire testing area. The rectangular cover blocks any flying wood fragments, improving protection and preventing injury to operators.

[0004] In the aforementioned mechanism, the pressure plate and hydraulic cylinder are fixedly connected, and the pressure plate cannot be disassembled. The test indicators are relatively simple, resulting in poor accuracy and reliability of the test results, which cannot meet the actual production needs. At the same time, the cover blocks the flying wood blocks. After the test is completed, the cover needs to be raised, and the blocked wood blocks will fall in all directions, causing inconvenience in environmental hygiene and cleaning.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a performance testing device for wooden pallet production, comprising a base, a pressure testing mechanism, and a protective mechanism. A testing platform is provided above the base, and a testing steel plate is provided on the upper surface of the testing platform. A wooden pallet to be tested can be placed on the testing steel plate. The pressure testing mechanism includes a rotary motor installed on one side of the top of the base. The output end of the rotary motor is connected to a central rotating shaft. A support plate is installed at the top of the central rotating shaft. Both ends of the support plate are provided with pressure-applying components. The protective mechanism includes a horizontally movable protective cover and a chip-collecting component on the outer wall of the protective cover.

[0008] Furthermore, mounting grooves are provided around the top surface of the test steel plate, and pressure sensors are embedded in the mounting grooves.

[0009] Furthermore, the pressure application assembly includes hydraulic cylinders installed at both ends of the top of the support plate. The actuator of the hydraulic cylinder passes through the interior of the support plate and is fixedly connected to a connecting block. Limiting grooves are opened on both sides of the connecting block. A pressure plate is detachably installed on the bottom surface of the connecting block. Multiple side plates are connected to both sides of the top surface of the pressure plate. A screw rod is horizontally inserted through the interior of the side plate. An adjusting block is installed at one end of the screw rod, and a limiting plate is connected to the other end of the screw rod. The limiting plate can be embedded in the limiting groove.

[0010] Furthermore, magnetic suction grooves are provided on both sides of the top surface of the base, and magnetic sliders are connected to both ends of the bottom of the protective cover. The magnetic sliders are slidably connected to the inside of the magnetic suction grooves.

[0011] Furthermore, the dust collection assembly includes a suction chamber fixedly installed on the outer wall of the protective cover, the suction chamber being connected to the inner side of the protective cover, an intercepting net being provided on the rear side of the inside of the suction chamber, a suction port being provided on the rear side wall of the suction chamber, a suction machine being installed on the rear side wall of the suction chamber, a discharge port being provided on the bottom wall of the suction chamber, and a collection chamber being detachably installed on the bottom wall of the suction chamber.

The quick switching improves the testing efficiency. With the setting of a limit groove, a side plate, a screw, an adjusting block, and a limit plate, the pressure plate can be disassembled for easy replacement. The quick disassembly and assembly method allows for switching between pressure plates of different sizes, improving the accuracy and reliability of the test results. By using a combination of a protective cover, magnetic slider, and magnetic chute, the protective cover can be moved to the outside of the pallet during testing to provide protection. At the same time, the setup of the suction chamber, interception net, suction machine, suction port, discharge port, and collection chamber can collect the splashed wood chips, preventing them from scattering everywhere and being difficult to clean, thus maintaining a clean and hygienic environment.

[0021] See attached document Figure 1-4 A performance testing device for wooden pallet production includes a base 1, a pressure testing mechanism, and a protective mechanism. A test platform 2 is positioned above the base 1, and a test steel plate 3 covers the upper surface of the test platform 2. A wooden pallet to be tested can be placed on the test steel plate 3. The pressure testing mechanism includes a rotary motor installed on one side of the top of the base 1. The output end of the rotary motor is connected to a central rotating shaft 4, and a support plate 5 is installed at the top of the central rotating shaft 4. Pressure-applying components are provided at both ends of the support plate 5. The protective mechanism includes a horizontally movable protective cover 6 and a chip-collecting component on the outer wall of the protective cover 6. Elastic clamping plates can be installed on both sides of the inner wall of the protective cover 6 to position the pallet. A data processing module is also included, comprising a data acquisition unit, a processor, and a display screen. The data acquisition unit collects data, the processor analyzes and processes the collected data, and the display screen can be used to display test data and processing results in real time.

[0022] In this embodiment, mounting grooves 300 are provided around the top surface of the test steel plate 3, and pressure sensors 7 are embedded inside the mounting grooves 300.

[0023] It should be noted that the data acquisition unit is connected to the pressure sensor 7 and is used to collect pressure resistance data during the test.

[0024] In this embodiment, the pressure application component includes hydraulic cylinders 8 installed at both ends of the top of the support plate 5. The actuator of the hydraulic cylinder 8 passes through the inside of the support plate 5 and is fixedly connected to a connecting block 9. Limiting grooves 900 are opened on both sides of the connecting block 9. A pressure plate 10 is detachably installed on the bottom surface of the connecting block 9. Multiple side plates 11 are connected to both sides of the top surface of the pressure plate 10. A screw 12 is horizontally inserted through the inside of the side plate 11. An adjusting block 13 is installed at one end of the screw 12. A limiting plate 14 is connected to the other end of the screw 12. The limiting plate 14 can be embedded in the inside of the limiting groove 900.

[0025] It should be noted that the downward extension of the actuator rod of the hydraulic cylinder 8 is used to push the pressure plate 10 downward, and the pressure plate 10 applies pressure to the tray. By rotating the adjusting block 13, the screw 12 is driven to move horizontally, so that the limiting plate 14 is embedded in the limiting groove 900, thus completing the downward rotation of the pressure plate 10. When disassembling, the adjusting block 13 is rotated in the opposite direction, so that the limiting plate 14 leaves the limiting groove 900, thus completing the disassembly of the pressure plate 10, which is convenient for later replacement.

[0026] In this embodiment, magnetic grooves 100 are provided on both sides of the top surface of the base 1, and magnetic sliders are connected to both ends of the bottom of the protective cover 6. The magnetic sliders are slidably connected to the inside of the magnetic grooves 100.

[0027] It should be noted that the magnetic slider moves along the inside of the magnetic groove 100, causing the protective cover 6 to move until it covers the entire test station, thus providing external protection. The top of the protective cover 6 is designed to be hollow, so that the test is not affected when the tray is high.

[0028] In this embodiment, the dust collection assembly includes a suction chamber 15 fixedly installed on the outer wall of the protective cover 6. The suction chamber 15 is connected to the inner side of the protective cover 6. An intercepting net 16 is provided on the rear side of the inside of the suction chamber 15. A suction port 1500 is opened on the rear side wall of the suction chamber 15. A suction machine 17 is installed on the rear side wall of the suction chamber 15. A discharge port 1501 is opened on the bottom wall of the suction chamber 15. A collection chamber 18 is detachably installed on the bottom wall of the suction chamber 15. It can be installed using various detachable connection methods, such as bolts or buckles.

[0029] It should be noted that the cracks caused by the compression of the pallet can be sucked into the suction chamber 15 by the suction force generated when the suction machine 17 is started. The wood chips are then intercepted by the interception net 16 and collected into the collection chamber 18 through the discharge port 1501 under the action of gravity. When a certain amount has been collected, the collection chamber 18 can be disassembled for cleaning and then reinstalled.

[0030] In this embodiment, a plurality of buffers 19 are provided between the test platform 2 and the base 1, and the buffers 19 are respectively located at the four corners of the test platform 2 and the base 1.

[0031] It should be noted that when the tray is subjected to a pressure test, the multiple buffers 19 can absorb the vertically downward energy, thus creating a certain energy buffer between the test platform 2 and the base 1.

[0032] The working principle of this invention is as follows: First, the wooden pallet to be tested is placed on top of the test steel plate 3, with the bottom surface of the wooden pallet in close contact with the pressure sensor 7. Then, the protective cover 6 is moved, and the magnetic slider moves along the inside of the magnetic groove 100, driving the protective cover 6 to move until the entire test station is covered. Next, the downward extension of the actuator rod of the hydraulic cylinder 8 pushes the pressure plate 10 downward, applying pressure to the pallet. The pressure sensor 7 monitors the pressure on the pallet in real time and transmits the data to the data acquisition unit. The data acquisition unit transmits the data to the processor for analysis and processing, and the processing results are displayed on the screen. When different pressure levels need to be applied, the rotating motor drives the central shaft 4 to rotate the support plate 5, so that the pressure application component at the other end switches to the top of the tray, and the same operation is performed to obtain pressure data. If the tray is of poor quality, it may break due to compression during the pressure test. The splashed wood chips can be sucked into the suction chamber 15 by the suction force generated when the suction machine 17 is started. They are then intercepted by the interception net 16 and collected into the collection chamber 18 through the discharge port 1501 under the action of gravity. When a certain amount has been collected, the collection chamber 18 can be disassembled for cleaning and then reinstalled.

[0033] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
