Description

Technical Field

[0001] The invention relates to the technical field of pillow testing equipment, in particular to a compression performance testing device for pillow production. Background Art

[0002] Sleep quality is related to human health. As one of the main components of bedding, the comfort of pillows has a direct and important impact on sleep quality. Pillows need to be tested for compression resistance during production. Pillow compression testing is an important test to evaluate the durability, support and service life of pillows. Compression testing can reflect the softness and hardness of the pillow. The softness and hardness of the pillow is an important indicator of pillow comfort. It not only affects the pressure relief between the human-pillow interface, but also affects the support of the pillow to the human head and neck and the health of the cervical spine. At present, when testing the compression resistance of pillows, an indentation hardness tester is used. After applying a certain pressure to the pillow, a certain deformation occurs in the pillow. When the pillow is pressed, the indentation hardness is detected. At the same time, after applying pressure to the pillow, the pressure is quickly unloaded and the rebound speed of the pillow is observed to test the rebound performance of the pillow after being compressed. For example, Chinese invention patent with authorization announcement number CN116026712A discloses a pillow softness and hardness grading quantitative testing equipment and testing and evaluation method, including a test platform for placing the pillow to be tested; a human head model made of rigid material simulating the physiological contours of the human head and neck, which is adjustably arranged above the test platform; and a mechanical performance testing device detachably connected to the human head model. However, the current pillow compression performance test has the following defects: Currently, when testing the compressive performance of pillows, an instrument is used to apply pressure to the pillow in a vertical direction. However, when the pillow is in use, the side position will be compressed by the cervical spine, and the pressure direction is oblique. Therefore, only using vertical pressure cannot reflect the pressure conditions of the pillow during actual use, resulting in inaccurate testing. When testing the rebound performance after compression, the load is not unloaded fast enough, so some pillows that rebound quickly will be affected by the load when rebounding, which is not conducive to testing the rebound performance of the pillow after compression.

[0003] For this reason, we propose a compressive performance testing device for pillow production to solve the above problems. Summary of the Invention

[0029] Example 3: See also Figure 1-13, which is the third embodiment of the present invention, and is based on the above two embodiments. When the present invention is used, the pillow is placed on the adsorption platform 12, and the cylinder 14 is used to drive the positioning plate 15 to push the pillow around to adjust the position of the pillow. Then, the position of the pressure test component 4 is adjusted through the position adjustment mechanism 3, and then the pressure cylinder 43 drives the die 46 to press the pillow to a specific deformation depth, and the pressure of the deformation depth is recorded to confirm the hardness of the pillow under different indentation depths. When testing, the position and angle of the pressure test component 4 are adjusted as needed, and multiple tests are performed. Then, the rebound performance test after pressure is performed, and the test is also performed at multiple positions. The pressure cylinder 43 drives the die 46 to press the pillow to a specific deformation depth. The pressure cylinder 43 drives the die 46 to return, and at the same time, the square rod 42 moves upward to quickly unload the load, and the rebound speed is recorded. An industrial camera can be used to record the specific rebound process; the inner plate 33 of the position adjustment mechanism 3 in the present invention can move in the horizontal direction, and the carrying block 35 can also move in the horizontal direction, so that the pressure test component 4 can be moved to different positions, which is convenient for testing different positions of the pillow, and the power arc slider 310 can move on an arc path in the power arc slide groove 39, and rotate and adjust the position with the through hole 37, so that the angle of pressure applied by the pressure test component 4 can be adjusted, and the pressure applied by the cervical spine on the edge of the pillow can be simulated, so that the entire compression test can simulate the actual force condition of the pillow, making the test data more accurate; when performing the post-compression rebound performance test, when unloading the load, when the output end of the pressure cylinder 43 returns, the same square rod 42 simultaneously drives the pressure cylinder 43 to move, so that the load can be quickly unloaded to avoid affecting the post-compression rebound test of the pillow.
