Description

Technical Field

[0001] This invention belongs to the field of EPE foam performance testing technology, specifically a multi-dimensional testing device for EPE foam performance. Background Technology

[0002] Multi-dimensional EPE foam refers to a type of EPE foam material with multiple properties and applications. It is usually made in the form of a continuous closed-cell structure and is a commonly used packaging and protective material. It is typically used for cushioning, isolation, and protection of goods. To ensure its effectiveness and reliability in protecting goods, EPE foam needs to be tested for tensile and compressive strength to assess the stability and load-bearing capacity of the material. When testing EPE foam, multi-dimensional EPE foam performance testing equipment is required, and the testing mechanisms set on it can test various properties of EPE foam separately.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6As shown in the embodiment of the present invention, a multi-dimensional performance testing device for pearl cotton includes a working plate 1. Movable plates 2 are provided on both sides of the working plate 1. A rotating shaft 3 is fixedly installed on the inner wall of the movable plate 2. A rotating ring 4 is rotatably installed on the outer wall of the rotating shaft 3. An arc-shaped flipping plate 5 is fixedly installed on the outer wall of the rotating ring 4. Elastic elements A6 are fixedly installed between the bottom of the two arc-shaped flipping plates 5 and the top of the two movable plates 2, respectively. A fixed pressure rod 7 is fixedly installed at the end of the arc-shaped flipping plate 5 away from the rotating ring 4. A compressive and tensile strength testing component is installed at the bottom of the working plate 1. The fixed pressure rod 7 detects the compressive and tensile strength of the pearl cotton through the compressive and tensile strength testing component. A pulling component is provided at the bottom of the working plate 1. When testing the pearl cotton, the pulling component pulls the two arc-shaped flipping plates 5. The arc-shaped flipping plates 5 rotate around the rotating shaft 3 using the rotating ring 4. The rotation of the arc-shaped flipping plates 5 drives the two fixed pressure rods 7 to... The components are flipped in opposite directions, at which point the elastic element A6 is in an elongated state. The pearl cotton to be tested is then placed on top of the work plate 1. After the pearl cotton is placed, the pulling assembly moves in the opposite direction, and the arc-shaped flipping plate 5 resets under the reverse elastic force of the elastic element A6. After the arc-shaped flipping plate 5 resets, the two fixed pressure rods 7, together with the two moving plates 2, clamp the two sides of the pearl cotton, thus fixing its position. Once the pearl cotton is fixed, testing begins. After testing is completed, the two fixed pressure rods 7 are lifted again by pulling the assembly, releasing the pearl cotton from its fixation. This achieves quick fixing and unfixing of the pearl cotton, making operation convenient and effectively improving testing efficiency. During testing, the compression and tensile testing components, together with the fixed pressure rods 7, compress the pearl cotton to achieve compression testing. Simultaneously, with the moving plates 2, the pearl cotton can be pulled from both sides to elongate, thus achieving tensile testing.

[0023] like Figure 1 As shown, a pearl cotton body 8 is provided on the top of the working plate 1. The pearl cotton body 8 is located between the moving plate 2 and the fixed pressure rod 7. A fixed frame 9 is fixedly installed on the back of the working plate 1. A single-axis cylinder 10 is fixedly installed at the bottom of the horizontal section of the fixed frame 9. A thickness detection plate 11 is fixedly installed on the output shaft of the single-axis cylinder 10. The thickness detection plate 11 is located above the pearl cotton body 8. The pearl cotton body 8 is located below the thickness detection plate 11. When performing thickness detection, the single-axis cylinder 10 is activated. The single-axis cylinder 10 will drive the thickness detection plate 11 to move down. After moving down, the thickness detection plate 11 will fit against the top of the pearl cotton body 8, thereby detecting the thickness of the pearl cotton body 8.

[0024] like Figures 1 to 6As shown, the pulling assembly includes a fixed base 12 fixedly installed at the bottom of the working plate 1. A dual-axis cylinder 13 is fixedly installed on the inner wall of the fixed base 12. A receiving block 14 is fixedly installed on the top of the arc-shaped flip plate 5. A connecting rope 15 is fixedly installed on the inner wall of the receiving block 14. A guide wheel 16 is fixedly installed on the side of the two moving plates 2 that are far apart from each other. The connecting rope 15 overlaps the outer wall of the guide wheel 16. When the fixed pressure rod 7 needs to be raised, the dual-axis cylinder 13 will retract. When the dual-axis cylinder 13 retracts, its two output shafts will simultaneously pull the connecting rope 15 through the pushing assembly. The connecting rope 15 will then pull the receiving block 14. When the receiving block 14 moves, it will drive the arc-shaped flip plate 5 to rotate around the rotating shaft 3. When the arc-shaped flip plate 5 rotates, it will drive the fixed pressure rod 7 at one end to be raised. Similarly, when the fixed pressure rod 7 needs to be lowered, the output shaft of the dual-axis cylinder 13 will extend, the connecting rope 15 will be released, the arc-shaped flip plate 5 will be reset, and the fixed pressure rod 7 will be lowered.

[0025] like Figures 3 to 6 As shown, the compressive and tensile testing assembly includes a connector 17 fixedly connected to the output shaft of the dual-axis cylinder 13. A compression ball 18 is fixedly installed on the outer wall of the connector 17, and a connecting rod 19 is fixedly installed on the outer wall of the compression ball 18. A force-bearing plate 20 is fixedly installed on the side of the rotating ring 4 away from the arc-shaped flip plate 5, and the connecting rod 19 is located inside the force-bearing plate 20. When the fixed pressure rod 7 descends under the action of the elastic element A6 to clamp the pearl cotton body 8, the two output shafts of the dual-axis cylinder 13 continue to extend, thereby pushing the connector 17 to continue moving to both sides. When the connector 17 moves, it drives the compression ball 18 to move. When the compression ball 18 moves, it squeezes the force-bearing plate 20. The squeezed force-bearing plate 20 drives the rotating ring 4 to rotate. When the rotating ring 4 rotates, it drives the arc-shaped flip plate 5 to rotate towards the pearl cotton body 8, thereby increasing the clamping force of the fixed pressure rod 7 on the pearl cotton body 8. The pressure is applied by the fixed pressure rod 7, which compresses the pearl cotton body 8 to measure the deformation and recovery ability of the pearl cotton under pressure, thereby assessing its protective performance in practical applications and realizing the compressive strength test of the pearl cotton body 8. When the fixed pressure rod 7 is pressed down to its maximum value, it can no longer move. At this time, the two moving plates 2 will be pushed to move to both sides by the continued extension of the dual-axis cylinder 13. When the moving plates 2 move to both sides, they will work with the fixed pressure rod 7 to stretch the pearl cotton body 8 to both sides. The extension of the dual-axis cylinder 13 stretches the pearl cotton body 8, and the stretching distance of the pearl cotton body 8 is measured. Based on the measurement results, the tensile strength of the pearl cotton body 8 can be calculated, so that the compressive and tensile strength tests of the pearl cotton body 8 can be performed quickly, increasing the convenience of the test and eliminating the need to use multiple devices to perform compressive and tensile tests separately, thus reducing costs.

[0026] like Figures 2 to 5As shown, a back positioning plate 31 is fixedly installed on the top of the work plate 1. Translation plates 21 are fixedly installed on the outer walls of both output shafts of the dual-axis cylinder 13. A centering positioning plate 22 is symmetrically fixedly installed on the outer wall of the translation plates 21. The outer wall of the centering positioning plate 22 is slidably connected to the inner walls of the work plate 1 and the moving plate 2. The end of the centering positioning plate 22 away from the translation plates 21 extends above the moving plate 2. When placing the pearl cotton body 8, the dual-axis cylinder 13 is first activated to retract, causing the fixed pressure rod 7 to lift. Then, the pearl cotton body 8 is placed above the work plate 1 and the pearl cotton... One side of the cotton body 8 is attached to the back positioning plate 31. Then, the dual-axis cylinder 13 is activated again to retract. During this retraction, the output shaft of the dual-axis cylinder 13 connected to the translation plate 21 will retract, thereby driving the two translation plates 21 to move closer. When the translation plates 21 move closer, they will drive the centering positioning plate 22 to move closer to each other. After the centering positioning plate 22 moves closer to each other, it will center the placed pearl cotton body 8, thereby achieving the effect of rapid positioning of the pearl cotton body 8, ensuring that the pearl cotton body 8 is in the middle position, and thus ensuring the accuracy of subsequent testing.

[0027] like Figure 2 and Figures 4 to 5 As shown, each of the two movable plates 2 has a stop block 23 fixedly installed on its top. The two stop blocks 23 are located on opposite sides of the two arc-shaped flip plates 5. After the device completes the tensile test, the output shaft of the dual-axis cylinder 13 will retract. When the output shaft retracts, the connecting rope 15 will pull the arc-shaped flip plate 5 upward through the receiving block 14. At this time, the pearl cotton body 8 can be removed. When the arc-shaped flip plate 5 is in contact with the stop block 23, the arc-shaped flip plate 5 will flip to its maximum value. At this time, the arc-shaped flip plate 5 can no longer rotate. As the output shaft of the dual-axis cylinder 13 continues to retract, it will pull the two movable plates 2 closer to each other, thereby achieving the effect of automatic reset of the movable plates 2.

[0028] like Figures 6 to 7 As shown, several elastic elements B24 are fixedly installed on the inner wall of one of the fixed pressure rods 7. A pressure block 25 is fixedly installed between one end of each elastic element B24. The pressure block 25 is slidably installed on the inner wall of one of the fixed pressure rods 7. When the pearl cotton body 8 that has been tested is removed, the output shaft of the dual-axis cylinder 13 will retract to lift the two fixed pressure rods 7. When the fixed pressure rods 7 are lifted, the elastic element B24 provided on the inner side of one of the fixed pressure rods 7 will extend under its own elastic force, causing the pressure block 25 to briefly press down on one side of the pearl cotton body 8. That is, when the two fixed pressure rods 7 are lifted, one side of the pearl cotton body 8 loses its fixation while the other side is temporarily fixed by the pressure block 25. At this time, the tension generated by the deformation of the pearl cotton body 8 can be relieved, thereby preventing the pearl cotton body 8 from flying out due to the tension generated by its own deformation when both sides of the pearl cotton body 8 lose their fixation at the same time, thus increasing the safety of the device during use.

[0029] like Figure 1 and Figure 5 As shown, limit rods 26 are symmetrically fixedly installed on the top of the thickness detection plate 11. The outer walls of the two limit rods 26 are slidably connected to the inner wall of the fixing frame 9. Limit sliders 27 are symmetrically fixedly installed on the outer wall of each centering positioning plate 22. The outer walls of the limit sliders 27 are slidably connected to the inner walls of the corresponding moving plates 2. The limit rods 26 limit the thickness detection plate 11 to ensure that the thickness detection plate 11 can move in a preset direction and prevent the thickness detection plate 11 from deviating during movement, which would affect the detection accuracy. The limit sliders 27 can ensure that the centering positioning plate 22 can move in a preset direction. At the same time, the limit sliders 27 can limit the output shaft of the dual-axis cylinder 13 to prevent the output shaft of the dual-axis cylinder 13 from tilting.

[0030] like Figures 1 to 3 As shown, a set of guide rails 28 are fixedly installed on the opposite sides of the working plates 1. The outer walls of the two sets of guide rails 28 are slidably connected to the inner walls of the two moving plates 2 respectively. The guide rails 28 can limit the movement of the moving plates 2, ensuring the stability and reliability of the moving plates 2 during movement, ensuring that the moving plates 2 can move along the preset trajectory, and preventing the moving plates 2 from deviating during movement.

[0031] like Figure 1 As shown, a base 29 is fixedly installed at the bottom of the working plate 1, and the top of the base 29 is fixedly connected to the bottom of the guide rail 28. The bottom of the moving plate 2 is slidably connected to the top of the base 29. Several support legs 30 are fixedly installed at the bottom of the base 29. The base 29 fixes the working plate 1 and the guide rail 28, increasing the stability of the connection between the guide rail 28 and the working plate 1. At the same time, the base 29 supports the moving plate 2 to ensure the stability of the moving plate 2. The support legs 30 support the entire device, keeping the device at a suitable height for easy use.

[0032] Working principle: When testing pearl cotton, the pulling assembly pulls two arc-shaped flip plates 5. The arc-shaped flip plates 5 rotate around the rotating shaft 3 using the rotating ring 4. The rotation of the arc-shaped flip plates 5 causes the two fixed pressure rods 7 to flip in a direction away from each other. At this time, the elastic element A6 is in an elongated state. Then, the pearl cotton to be tested is placed on top of the working plate 1. After the pearl cotton is placed, the pulling assembly moves in the opposite direction. The arc-shaped flip plates 5 will reset under the action of the reverse elastic force of the elastic element A6. After the arc-shaped flip plates 5 reset, the two fixed pressure rods 7 will cooperate with the two The movable plate 2 clamps both sides of the pearl cotton, thus fixing its position. After the pearl cotton is fixed, the test begins. After the test is completed, the two fixing rods 7 are lifted again by pulling the assembly, which releases the pearl cotton from the fixation. This achieves the effect of quickly fixing and unfixing the pearl cotton, making the operation convenient and effectively improving the testing efficiency. During the testing process, the compression and tensile testing assembly, together with the fixing rods 7, compresses the pearl cotton to achieve compression testing. At the same time, with the movable plate 2, the pearl cotton can be pulled from both sides to elongate, thereby achieving tensile testing.

[0033] When the fixed pressure rod 7 needs to be raised, the dual-axis cylinder 13 retracts. During this retraction, the output shafts at both ends of the dual-axis cylinder 13 simultaneously pull the connecting rope 15 via the push assembly. The connecting rope 15 then pulls the receiving block 14. As the receiving block 14 moves, it causes the arc-shaped flip plate 5 to rotate around the rotating shaft 3. The rotation of the arc-shaped flip plate 5 causes one end of the fixed pressure rod 7 to rise. Similarly, when the fixed pressure rod 7 needs to be lowered, the output shaft of the dual-axis cylinder 13 extends, releasing the connecting rope 15 and resetting the arc-shaped flip plate 5, thus lowering the fixed pressure rod 7. After the fixed pressure rod 7 lowers under the action of the elastic element A6 and clamps the pearl cotton body 8, the two output shafts of the dual-axis cylinder 13 continue to extend, pushing the connecting piece 17 to continue moving to both sides. The movement of the connecting piece 17 causes the compression ball 18 to move, which in turn compresses the force plate 20. The compressed force plate 20 then causes the rotating ring 4 to rotate. 4. When rotating, the arc-shaped flipping plate 5 will rotate towards the pearl cotton body 8, thereby increasing the clamping force of the fixed pressure rod 7 on the pearl cotton body 8. At this time, the fixed pressure rod 7 will squeeze the pearl cotton body 8, measuring the degree of deformation and recovery ability of the pearl cotton under pressure, thereby evaluating its protective performance in practical applications. When the fixed pressure rod 7 is pressed down to the maximum value, the fixed pressure rod 7 can no longer move. At this time, under the action of the continued extension of the dual-axis cylinder 13, it will push the two moving plates 2 to move to both sides. When the moving plates 2 move to both sides, they will cooperate with the fixed pressure rod 7 to stretch the pearl cotton body 8 to both sides. By extending the dual-axis cylinder 13, the stretching distance of the pearl cotton body 8 can be measured. Based on the measurement results, the tensile strength of the pearl cotton body 8 can be calculated, thereby quickly testing the compressive and tensile strength of the pearl cotton body 8, increasing the convenience of testing, eliminating the need to use multiple devices to perform compressive and tensile tests separately, and reducing costs.

[0034] When placing the pearl cotton body 8, first activate the dual-axis cylinder 13 to retract, raising the fixed pressure rod 7. Then, place the pearl cotton body 8 above the work plate 1, ensuring one side of the pearl cotton body 8 is flush with the back positioning plate 31. Next, activate the dual-axis cylinder 13 again to retract. During this retraction, one section of the output shaft connected to the translation plate 21 retracts, causing the two translation plates 21 to move closer. As the translation plates 21 move closer, they cause the centering positioning plate 22 to move closer together. This centering positioning plate 22 then centers the placed pearl cotton body 8, achieving rapid positioning and ensuring the pearl cotton body 8 is in the center position, thus guaranteeing... To ensure accuracy during subsequent testing, when the pearl cotton body 8 is removed after testing, the output shaft of the dual-axis cylinder 13 will retract, causing the two fixed pressure rods 7 to lift. When the fixed pressure rods 7 are lifted, the elastic element B24 on the inner side of one of the fixed pressure rods 7 will extend under its own elastic force, causing the pressure block 25 to briefly press down on one side of the pearl cotton body 8. That is, when the two fixed pressure rods 7 are lifted, one side of the pearl cotton body 8 loses its fixation while the other side is temporarily fixed by the pressure block 25. At this time, the tension generated by the deformation of the pearl cotton body 8 can be relieved, thereby preventing the pearl cotton body 8 from flying out due to the tension generated by its own deformation when both sides of the pearl cotton body 8 lose their fixation at the same time, thus increasing the safety of the device during use.
