Technical Field
The utility model relates to a fibre flocculus resilience performance measuring equipment technical field, in particular to fibre flocculus compression resilience performance testing arrangement.
Background
As is known, the compression resilience of the fiber flocculus is evaluated through two indexes, namely a compression rate and a recovery rate, wherein the compression rate represents the fluffiness degree of the flocculus, and the recovery rate represents the elasticity maintenance of the flocculus and is an important index of the wearability. The compression rate index is reasonably selected according to the application of the product, the larger the compression rate index is, the better the compression rate index is, for example, if the cotton clothes are made of the flocculus with the too large compression rate, the appearance of the cotton clothes is bloated, and the like. However, the relative recovery index of the fiber flocculus for the clothes and the covered bedding is higher.
At present, the methods adopted by the current effective test standard in China are consistent, and the main working principle is that under the action of certain time and pressure, the sample generates compression and decompression rebound recovery in the thickness direction, and the thickness values of the sample at different pressures are measured so as to calculate the compression and rebound performance of the sample. However, the existing testing device has certain defects that in the testing process, firstly, because some fiber flocculus samples are in a loose state, the working platform is often inclined because of instability when being pressed or after a weight is taken down, the detection result is influenced, and the detection failure can be caused in serious cases. Secondly, because the pressing plate for compressing the fiber flocculus cannot move, the inclination adjustment cannot be carried out according to the difference of the thickness of the whole fiber flocculus, so that the final test result is inaccurate and unstable.
Patent CN 212159331U discloses a textile fiber flocculus compression resilience performance testing arrangement, place the workstation with the textile fiber flocculus on, later place the preforming on the textile fiber flocculus to place the weight on the preforming and make textile fiber flocculus compression deformation, because the workstation rotates with the bulb through the ball seat and is connected, consequently the workstation can rotate base automatically relatively, realizes that the workstation adjusts to the level, leads to locking device behind workstation adjustment to the horizontality and fixes the ball seat ball head locking relatively. After taking off the weight, the textile fiber flocculus replies, because four corners of preforming all are located the measuring stick that the homonymy corresponds, consequently can directly read the scale interval through preforming upper end surface place position to obtain the distance between preforming and the workstation worksheet, measurement accuracy is high, and convenient to use has improved efficiency of software testing.
Further, as disclosed in patent CN 204188476U, a cylinder-based automatic centering and pressing type compressed resilience tester for silk floss quilt is disclosed. The purpose is that the tester that provides has automatic centering function when pressurizeing the cotton-wadded quilt. The technical scheme is as follows: the automatic centering pressurization type silk floss quilt compression resilience tester based on the cylinder comprises a frame, a pressurization mechanism, data display equipment, a test pressing sheet, a distance measuring sensor and a control module; the control module is electrically connected with the sensor and the data display equipment; the pressurizing mechanism is a walking pressurizing mechanism and comprises two single-rod cylinders which can be horizontally positioned in two slideways at the top of the frame in a sliding way and have the same output force and a double-rod cylinder which transversely pushes the two single-rod cylinders; the two slideways are arranged on the top plate of the frame in parallel and symmetrically at a certain distance; the two single-rod cylinders are vertically fixed on the sliding plate, and two ends of the sliding plate are respectively and slidably arranged in the two slideways one by one; the bottom ends of the piston rods of the two single-rod air cylinders are respectively fixed with a pressing plate. The device can directly apply force to the test pressing sheet in the vertical direction through the walking type pressurizing mechanism, the falling points of the two pressing plates on the test pressing sheet can be accurately symmetrical to the central position of the test pressing sheet through the moving adjustment of the sliding plate, and the force application size can be efficiently changed through the combined motion of the air cylinders; then through the direct accurate pressurization mode, simplified the pressurization mechanism, improved pressurization efficiency, greatly promoted the measuring accuracy of silk floss quilt compression resilience.
Although the above patent can also achieve the purpose of improving the accuracy of measuring the compressed resilience of the silk floss, there are also disadvantages that the final test result is relatively poor in accuracy and stability because the pressing plate for compressing the fiber flocculus is immovable and cannot be adjusted obliquely according to the difference of the thickness of the whole fiber flocculus.
