Description

Technical Field

[0001] The invention belongs to the technical field of air fiber pillow core production, and in particular relates to a pressure resistance detection device for air fiber pillow core production. Background Art

[0002] Air fiber pillow cores are made of polyester and other high molecular polymers, and are made into three-dimensional hollow fiber through a special process. These fibers are interwoven to form a mesh with air channels inside, which makes it both breathable and can quickly dissipate heat to keep the head cool. It also has high elasticity and excellent support, can fit the curve of the head and neck, disperse pressure, and maintain the health of the cervical spine. In addition, its material is not easy to breed bacteria and mites, is easy to clean, and has strong durability. It is an ideal bedding choice for people who pursue a high-quality sleep experience. The folding test of air fiber pillow core is an important part of controlling product quality. In actual use, the pillow core may be subjected to folding pressure due to folding, storage, transportation and squeezing. If its structural strength is insufficient, it is easy to produce irreversible deformation or even damage, affecting the subsequent use effect and lifespan. The folding test simulates this scenario and folds the air fiber pillow core in a prescribed manner. During the folding process, professional equipment is used to accurately control the applied pressure, loading speed and holding time. At the same time, sensors and other devices are used to monitor the internal stress distribution, surface deformation degree, rebound performance and other data of the pillow core in real time.

[0003] Most of the existing compression testing devices adopt a single testing mode of fixed pressure plates pressing up and down, which can only simulate static pressure in the vertical direction and cannot fully reflect the compression characteristics of the pillow core under complex working conditions such as multi-angle force, folding and squeezing in actual use. The compression testing of the pillow core in the folded state currently mainly relies on manual operation. Due to the significant differences in the force application methods, force levels and action time of different operators, the testing process lacks standardization and quantitative indicators. Not only is the testing efficiency low, but the test results are also highly discrete and have poor repeatability. It is difficult to accurately evaluate the structural strength and resilience of the pillow core in the folded state. In addition, there is a risk of local damage to the pillow core due to uneven force application during manual testing, which affects the accuracy of product qualification rate determination.

Detailed implementation manners

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0019] Such as Figures 1-11An anti-compression detection device for the production of air fiber pillow cores as shown, includes a bottom plate 1. In the middle of the upper end of the bottom plate 1, there is a support platform 2 connected. The support platform 2 can support a placement platform 3. At the upper end of the support platform 2, there is a placement platform 3 connected. On one side of the upper end of the placement platform 3, there is an electric control slide rail 6 connected, which is convenient for the slider 7 to move. Furthermore, it can drive the box body 8 and the support plate 17 to slide left and right, and can flexibly detect various parts of the pillow core, ensuring a comprehensive evaluation of the anti-compression performance of the pillow core. In the middle of the upper end of the electric control slide rail 6, there is a slider 7 slidably connected, which is convenient for fixing the lower end of the box body 8. At the upper end of the slider 7, there is a box body 8 connected. On both sides of the upper end of the box body 8, there are openings 9 provided. The lower end of the detection plate 10 can be retracted into the interior of the box body 8. When performing other detection processes on the pillow core or moving the device, the detection plate 10 is retracted, which can prevent it from interfering with other components or objects, ensuring the safety and smoothness of the entire detection process. On both sides of the lower end of the inner wall of the box body 8, there are detection plates 10 connected. The detection plates 10 can push the two ends of the pillow core upward. The upper ends of the two detection plates 10 penetrate through the box body 8 and extend into the interior of the box body 8. The two detection plates 10 are respectively located inside the two openings 9. On both sides of the lower end of the box body 8, there are moving components connected. The moving components can push to adjust the height of the detection plates 10. In the middle of the upper end of the box body 8, there is a support plate 17 connected, which can place the pillow core, facilitating cooperation with the height above the detection plates 10, so that the placement position of the pillow core is above the same horizontal plane. Both ends of the support plate 17 are respectively in contact with the upper parts of one side of the two detection plates 10. On the other side of the two detection plates 10, there are limit components connected. The limit components can limit the two ends of the pillow core. In the middle of the lower end of the inner wall of the box body 8, there is a clamping component connected, which can facilitate fixing the pillow core above the support plate 17. At the upper end of the placement platform 3, there is a connecting column 4 connected, which is convenient for supporting the control box 5, the detection hydraulic cylinder 36 and the detection block 37. On one side of the connecting column 4, there is a control box 5 connected. On one side of the lower end of the control box 5, there is a detection hydraulic cylinder 36 connected. At the lower end of the detection hydraulic cylinder 36, there is a detection block 37 connected; The upper surface of the support plate 17 is specially anti-slip treated, which can effectively prevent the pillow core from sliding when placed. The electric control slide rail 6 connected to one side of the upper end of the placement platform 3 is equipped with a high-precision linear guide system. Driven by a servo motor, it can achieve precise positioning and rapid movement of the slider 7 in the horizontal direction. When the slider 7 slides on the electric control slide rail 6, it drives the box body 8 and the support plate 17 to slide left and right. This flexible movement method enables the detection device to accurately detect different positions of the pillow core. Whether it is the edge part or the central area of the pillow core, by adjusting the position of the slider 7, the detection equipment can be aligned with the corresponding part, thus ensuring a comprehensive evaluation of the anti-compression performance of the pillow core.

[0020] The moving assembly includes a frame 11, which can protect the screw rod 13 and the moving block 14. The number of the frames 11 is two groups. A driving motor 12 is connected to the middle of one side of the two frames 11. The driving motor 12 can drive the screw rod 13 to rotate. The output ends of the two driving motors 12 extend through the inside of the two frames 11 respectively. The output ends of the two driving motors 12 are connected to the screw rod 13. The screw rod 13 is a bidirectional thread setting, which can synchronously adjust the position of the two moving blocks 14. The moving blocks 14 are slidably connected to both sides of the outer walls of the two screw rods 13. , the upper ends of the moving blocks 14 extend through and extend to the upper ends of the two frames 11, and the middle of the upper ends of the frames 11 are connected with an electric telescopic rod 30, which can push the clamping assembly to move upward, and the middle of the upper ends of the multiple moving blocks 14 are connected with cylinders 15, and the upper ends of the multiple cylinders 15 are connected with push blocks 16, which are convenient for pushing the multiple push blocks 16 to move upward, and can drive the detection plate 10 to move upward. The number of cylinders 15 and push blocks 16 is four groups, and one side of the multiple push blocks 16 is connected to the upper parts of both sides of the two detection plates 10, and the multiple push blocks 16 are respectively located inside the two openings 9; When the pillow core is folded in half, the position of the push block 16 is pushed by the cylinder 15, and multiple push blocks 16 drive the two detection plates 10 to move upward. When the two detection plates 10 move upward, the two ends of the pillow core can be driven to move upward, so as to achieve the effect of detecting the folding of the pillow core. The bidirectional thread setting of the screw rod 13 can synchronously adjust the positions of the two moving blocks 14, so that the two moving blocks 14 can move toward or away from each other at the same speed, thereby accurately adjusting the horizontal position of the detection plate 10. The electric telescopic rod 30 connected to the middle part of the upper end of the frame 11 has a multi-stage telescopic structure, which can flexibly adjust the height of the clamping assembly according to pillow cores of different specifications. By controlling the extension and contraction of the cylinder 15, multiple push blocks 16 can be pushed upward, thereby driving the detection plate 10 to adjust its height in the vertical direction, which can ensure the smooth pushing of the detection plate 10, so that the detection plate 10 is evenly stressed during the lifting process, avoiding tilting or jamming, and ensuring the smooth progress of the detection work.

[0021] The limiting component includes a connecting plate 18. Installation plates 19 are connected to both sides of the connecting plate 18. The installation plates 19 are arranged in a semi-circular arc shape. The installation plates 19 can guide the rotation position of the limiting plate 21 to ensure the stability of the limiting plate 21 during rotation. A first motor 20 is connected to the upper part of one side of one of the installation plates 19. By operating the first motor 20, the limiting plate 21 can be driven to rotate. The limiting plates 21 at both ends of the box body 8 are turned upwards. Since the upper end of the limiting plate 21 is inclined, the limiting plate 21 can limit both ends of the pillow core, avoiding the situation that one end of the pillow core falls off when the detection plate 10 moves upwards. The output end of the first motor 20 extends through to one side of one of the installation plates 19. The output end of the first motor 20 is connected to the limiting plate 21. One end of the limiting plate 21 is rotatably connected to one side of the installation plate 19. Anti-slip strips are connected to both sides of the limiting plate 21 to increase the friction when the limiting plate 21 contacts one end of the pillow core. The upper end of the limiting plate 21 is inclined. Both lower parts of both sides of the limiting plate 21 are connected with rotating shafts. One end of the rotating shaft is connected to the output end of the first motor 20. A stabilizing block 22 is fixed at the connection between the installation plate 19 and the rotating shaft. A stabilizing rod 23 is connected to one side of the two stabilizing blocks 22 away from the output end of the first motor 20, which can improve the stability of the limiting plate 21 during rotation. One end of the two stabilizing rods 23 respectively extends through to one side of the two installation plates 19. Stabilizing grooves 24 are respectively opened at the positions corresponding to the two stabilizing rods 23 on one side of the two installation plates 19 to facilitate the sliding of the stabilizing rods 23 inside the stabilizing grooves 24. The two stabilizing rods 23 are respectively sliding inside the two stabilizing grooves 24; The installation plates 19 on both sides of the limiting plate 21 can guide the rotation position of the limiting plate 21. The first motor 20 connected to the upper part of one side of one of the installation plates 19 is a stepper motor, which can achieve precise angle control. When the first motor 20 operates, it can drive the limiting plate 21 to rotate around the rotating shaft. The limiting plates 21 at both ends of the box body 8 are turned upwards. Since the upper end of the limiting plate 21 is inclined, it can closely fit both ends of the pillow core during the flipping process, forming an effective limit on the pillow core to ensure that the pillow core will not fall off during the upward movement of the detection plate 10 or other detection operations. The stabilizing blocks 22 and the stabilizing rods 23 connected to the middle parts of the outer walls of the two rotating shafts improve the stability of the limiting plate 21 during rotation. When the limiting plate 21 rotates, the stabilizing rod 23 slides inside the stabilizing groove 24, providing reliable support and guidance for the rotation of the limiting plate 21, ensuring that the limiting component always maintains a stable and reliable working state during the entire detection process.

[0022] The clamping assembly includes a slide bar 25, which improves the stability of the buffer block 26 during sliding and prevents the buffer block 26 from shifting. Both sides of the outer wall of the slide bar 25 are slidably connected with buffer blocks 26. The lower ends of the two buffer blocks 26 are respectively slidably connected with the lower end of the inner wall of the box body 8. The middle parts of the upper ends of the two buffer blocks 26 are rotatably connected with support rods 27. The upper ends of the two support rods 27 are rotatably connected with an adjustment plate 28. The adjustment plate 28 can adjust the height positions of the two support plates 29. The middle parts of both sides of the adjustment plate 28 penetrate through both sides of the box body 8. Both sides of the adjustment plate 28 are connected with support plates 29. The support plates 29 can support the clamping rods 32. The lower ends of the two support plates 29 are respectively connected with the upper ends of two electric telescopic rods 30. One side of the lower end of each of the two support plates 29 is connected with a second motor 31. The second motor 31 can drive the clamping rod 32 to rotate 90 degrees. Then, the two clamping rods 32 are located above the pillow core, and the pillow core is limited above the support plate 17, preventing the pillow core from shifting when the two detection plates 10 push up the two ends of the pillow core. The output ends of the two second motors 31 respectively penetrate through the upper ends of the two support plates 29, and the output ends of the two second motors 31 are connected with clamping rods 32. Slide rings 33 are connected to the upper ends of both support plates 29 to improve the stability of the clamping rod 32 during rotation. One side of the lower end of each of the two clamping rods 32 is connected with a connecting rod 34. The lower ends of the two connecting rods 34 are connected with a connecting block 35. The lower ends of the two connecting blocks 35 are respectively slid on one side of the upper ends of the two slide rings 33. The connecting block 35 is arranged in an inverted U-shaped structure; The slide bar 25 can effectively improve the stability of the buffer block 26 during sliding and prevent the buffer block 26 from shifting during the sliding process. The support rods 27 rotatably connected to the middle parts of the upper ends of the two buffer blocks 26 adopt an adjustable-angle joint bearing connection method, which can automatically adjust the inclination angle according to the lifting height of the adjustment plate 28 to ensure the smoothness of the adjustment plate 28 during the lifting process. The electric telescopic rod 30 can quickly and accurately adjust the height of the support plate 29 according to different specifications of the pillow core to match the height of the pillow core. The second motor 31 can drive the clamping rod 32 to rotate 90 degrees. When the clamping rod 32 rotates above the pillow core, it can firmly limit the pillow core above the support plate 17, effectively preventing the pillow core from shifting when the two detection plates 10 push up the two ends of the pillow core. The slide rings 33 connected to the upper ends of the two support plates 29 can greatly improve the stability of the clamping rod 32 during rotation. The lower ends of the two connecting blocks 35 are respectively slid on one side of the upper ends of the two slide rings 33. The inverted U-shaped structure design of the connecting block 35 can not only ensure the stability of the clamping rod 32 during rotation but also facilitate the connection with an external driving mechanism to achieve precise control of the clamping rod 32, ensuring that the clamping assembly can reliably fix the pillow core during the entire detection process and providing a strong guarantee for accurate compressive testing.

[0023] Working principle: When using the device, place the air fiber pillow core to be detected on the support plate 17. At this time, the pillow core body is located between the two detection plates 10. Start the electric control slide rail 6, and the slider 7 drives the box body 8, the support plate 17 and the pillow core as a whole to slide left and right, so that the pillow core is in a suitable initial position for pressure detection, preparing for subsequent detection; Start the first motor 20, drive the limiting plate 21 to rotate around the rotating shaft, and the limiting plate 21 turns upward to fit the two ends of the pillow core for limiting. The stabilizing block 22 and the stabilizing rod 23 slide in the stabilizing groove 24 to ensure the stability of the limit. The anti-slip strip increases the friction force to ensure that the pillow core does not displace during the pressure detection. After the pillow core is fixed and limited during the pressure detection, through the cooperation of the electric control slide rail 6 and the slider 7, accurately adjust the position of the pillow core to align the detection block 37 with the part to be detected. Start the detection hydraulic cylinder 36, push the detection block 37 to move downward, apply pressure to the pillow core in the original state, simulate the pressure situation in actual use, set the pressure parameters and detection time through the control box 5, and monitor the pressure data during the detection process in real time. According to the deformation, resilience, etc. of the pillow core during the pressure process, judge whether the compressive performance of the pillow core meets the production standards. During the detection process, the pillow core can be moved multiple times through the electric control slide rail 6 and the slider 7 to perform pressure detection on different parts; Adjust the position of the pillow core through the electric control slide rail 6 and the slider 7 to make it in a position suitable for folding detection. Start the electric telescopic rod 30, which pushes the support plate 29 upward. The support plate 29 drives the adjustment plate 28 to move upward synchronously. During the upward movement of the adjustment plate 28, the two support rods 27 rotatably connected to the middle of the lower end thereof rotate. Since the lower ends of the two buffer blocks 26 are slidably connected to the lower end inner wall of the box body 8 and the buffer blocks 26 slide on both sides of the outer wall of the slide rod 25, the slide rod 25 ensures the stability of the buffer blocks 26 during sliding and prevents the buffer blocks 26 from displacing. As the adjustment plate 28 rises, the support rods 27 rotate around the rotation connection point with the buffer blocks 26, change the inclination angle, and drive the adjustment plate 28 to rise smoothly, so that components such as the support plate 29 and the clamping rods 32 rise to a suitable height. Subsequently, the second motor 31 drives the clamping rods 32 to rotate 90 degrees, so that the two clamping rods 32 are located above the pillow core. The electric telescopic rod 30 drives the support plate 29 and the clamping rods 32 to move downward, and the two clamping rods 32 press the upper ends on both sides of the pillow core, which can limit the pillow core on the support plate 17, and the two limiting plates 21 continuously fit the two ends of the pillow core to limit the pillow core; Subsequently, a plurality of cylinders 15 on both sides are used to push a plurality of push blocks 16 to move upward, and then the two detection plates 10 can be pushed to move upward. Since one end of the connecting plate 18 contacts the detection plate 10 and one end of the connecting plate 18 is connected to the limiting plate 21, when the two detection plates 10 move upward on both sides, the first motor 20 works to drive the rotating shaft and the limiting plate 21 to rotate. The limiting plate 21 rotates 90 degrees, and the limiting plate 21 and the connecting plate 18 are in a horizontal state. Since the pillow core is located above the two detection plates 10, when the two detection plates 10 move upward, the two ends of the pillow core can be pushed to move upward, and both sides of the lower end of the pillow core are lifted, so that both ends of the pillow core are inclined. When the detection plates 10 are completely moved out of the interior of the box body 8, since the two clamping rods 32 limit the middle part of the upper end of the pillow core, the pillow core is squeezed into a V shape by the two detection plates 10. The driving motor 12 is started to rotate the lead screw 13, driving a plurality of moving blocks 14 to move towards the middle. The moving blocks 14 push the detection plates 10 through the push blocks 16 to clamp the pillow core towards the middle. According to the preset folding degree, the clamping force and displacement of the detection plates 10 are precisely controlled to fold the pillow core to the corresponding angle or degree. After folding is completed, check whether there are damages, deformations, etc. at the bending part of the pillow core to preliminarily evaluate the flexibility and structural strength of the pillow core. After the detection and reset of the folding detection are completed, each component is reset again, and the detection plates 10, the limiting plates 21, etc. return to the initial state, and the device is ready for the next detection task.
