Abstract
Description
Technical Field
[0001] This invention relates to the field of anti-hair-drilling testing technology, and specifically to an anti-hair-drilling testing device and method. Background Technology
[0002] Textile products filled with down feathers, such as down comforters, have advantages such as being lightweight, highly warm, and breathable. For these products, a feather-proof test is required to ensure product quality.
[0003] Current methods for testing down leakage resistance typically involve a rotating chamber method. This method involves preparing a sample bag of a specific size from a fabric sample, filling it with a certain mass of down or feather filling, or using down or feather products directly as samples. The sample bag or sample is placed in a rotating chamber of a down leakage resistance testing machine containing rubber balls. The rotating chamber rotates at a constant speed, raising the rubber balls to a certain height and impacting the sample inside the chamber. This simulates the various compression, rubbing, and collision effects experienced by down or feather products during use. The down leakage resistance of the fabric or down or feather product is evaluated by counting the number of feathers, down, down filaments, and down fibers that emerge from the sample bag or sample. However, this method has the following drawbacks: the current technology only achieves the compression and rubbing effect through the collision between the rubber ball and the sample bag. However, the movement of the rubber ball within the rotating chamber is random and cannot effectively compress and rub the sample bag. Therefore, the evaluation effect on down leakage resistance is poor. Summary of the Invention
[0004] The purpose of this invention is to provide an anti-hair-drilling test device and method, which solves the technical problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A hair-drilling resistance testing device includes a base, a control device, a test box connected to the control device, and a vertical plate. The control device drives the test box to rotate forward or backward. A notch is provided at the end of the test box opposite to the control device, and the size of the notch is the same as the size of the test box. A baffle for closing the notch is slidably sealed within the notch. Two channel groups are provided on the baffle, and each channel group includes multiple channels arranged in a straight line on the baffle. A sealing plate is rotatably connected to each channel via a torsion spring. A linear movement mechanism capable of axial movement of the test box is provided on the vertical plate. A transmission mechanism is provided on the linear movement mechanism. Two telescopic devices are symmetrically arranged on the transmission mechanism. Each telescopic device is provided with a kneading structure, which is located on the transmission mechanism and can pass through the transmission mechanism and the corresponding channel. A positioning mechanism for positioning the test box is provided on the outer wall of the control device. One end of the test box is rotatably connected to a bracket fixedly connected to the base. The kneading structure, after passing through the corresponding channel, is opened by the compression of the linear movement mechanism and can be reset under the action of elasticity.
[0006] As a preferred embodiment of the present invention, the bracket includes an annular sleeve rotatably fitted at the end of the test box. The annular sleeve is fixedly connected to a support plate fixedly connected to the base by a plurality of connecting rods. The support plate is provided with a working groove for the transmission mechanism and the kneading structure to pass through.
[0007] In a preferred embodiment of the present invention, the transmission mechanism includes a transmission rod slidably connected to the upright plate, and the transmission rod is connected to the linear motion mechanism through a connecting seat. A connecting plate is provided at the end of the transmission rod, and a connecting shaft is fixedly connected to the connecting plate. The axis of the connecting shaft coincides with the rotation center line of the test box. An intermediate plate is fixedly connected to the end of the connecting shaft, and the intermediate plate is rotatably connected to the baffle. The telescopic device is mounted on the connecting shaft through a mounting plate.
[0008] As a preferred embodiment of the present invention, the kneading structure includes multiple limiting frames fixedly disposed on the middle plate and pressure strips connected to the ends of the telescopic device, and each limiting frame is connected to a corresponding channel. Multiple pressure seats are equally spaced along the length of the pressure strip, and two connecting strips are symmetrically rotatably connected to each pressure seat by a torsion spring. A pressure roller is rotatably connected to the end of each connecting strip. Multiple passages corresponding to the positions of the channels are opened on the middle plate. When the connecting strip is not extended into the test chamber, the two connecting strips in the same limiting frame abut against the inner wall of the limiting frame by the elastic force of the torsion spring, and when the connecting strip is extended into the test chamber, the two connecting strips on the same pressure seat open by the elastic force.
[0009] As a preferred embodiment of the present invention, the limiting frame includes two U-shaped plates symmetrically arranged on the middle plate, and the openings of the two U-shaped plates are opposite to each other.
[0010] As a preferred embodiment of the present invention, the multiple pressing seats on the two kneading structures are staggered relative to each other.
[0011] As a preferred embodiment of the present invention, the positioning mechanism includes a pushing device disposed on the outer wall of the control device, the movable end of the pushing device is provided with a positioning rod, and the outer wall of the test box is provided with a fixing rod.
[0012] A test method for an anti-hair-drilling test device includes the following steps: S100: Before testing, clean the fibers inside the test chamber, wipe the six rubber balls to be used clean, place the rubber balls inside the test chamber, and wipe the sample bag containing wool clean. S200: Place the sample bag inside the test chamber, control the test chamber to rotate via the control device, set the number of rotations to one thousand, start the control device, and the test chamber will begin to rotate. S300: After the test chamber has rotated 1,000 revolutions, the rubber ball is removed from the test chamber, and the wool fibers on the surface of the rubber ball are carefully counted. Then the test chamber is closed, the linear movement mechanism is started, and the kneading structure is driven into the test chamber. At the same time, the telescopic device drives the kneading structure to squeeze the sealing plate to rotate. When the kneading structure squeezes the sample bag to fit against the inner side wall of the test chamber, the linear movement mechanism is closed. S400, activate the telescopic device to extend and shorten, and the two connecting strips on the same pressure seat cyclically open and close to rub the sample bag; S500: After the telescopic device has completed the required number of extensions and retractions, open the test box, remove the sample bag, carefully count the wool fibers inside the test box, record the data, and give the test results based on the data comparison and judgment criteria.
[0013] Compared with the prior art, the present invention has the following advantages: This invention places a rubber ball and a sample bag in a test chamber and drives the test chamber to rotate via a control device to perform a lint-proof test on the sample bag. After the test is completed, the rubber ball is removed, and then a kneading structure is driven into the test chamber by a linear movement mechanism and a telescopic device. This causes multiple pressure rollers to squeeze and knead the sample bag, avoiding the random collision of the rubber ball to simulate squeezing and kneading, thus improving the accuracy of the evaluation.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] like Figures 1 to 8 As shown, the present invention provides an anti-hair-drilling test device, including a base 1, a control device 2, a test chamber 3 connected to the control device 2, and a vertical plate 4. The control device 2 drives the test chamber 3 to rotate forward or backward. A notch 5 is provided on the end of the test chamber 3 opposite to the control device 2, and the size of the notch 5 is the same as the size of the test chamber 3. A baffle 6 for closing the notch 5 is slidably and sealingly connected inside the notch 5. Two channel groups are provided on the baffle 6, and each channel group includes multiple channels 7 arranged in a straight line on the baffle 6. Each channel 7 is connected by a torsion... A sealing plate 8 is rotatably connected to a force spring. A linear moving mechanism 9 capable of axially moving the test box 3 is provided on the upright plate 4. A transmission mechanism 10 is provided on the linear moving mechanism 9. Two telescopic devices 11 are symmetrically arranged on the transmission mechanism 10. Each telescopic device 11 is provided with a kneading structure 12. The kneading structure 12 is located on the transmission mechanism 10 and can pass through the transmission mechanism 10 and the corresponding channel 7. A positioning mechanism 13 for positioning the test box 3 is provided on the outer wall of the control device 2. One end of the test box 3 is rotatably connected to a bracket 14 fixedly connected to the base 1. Among them, the kneading structure 12 is opened by the squeezing of the linear movement mechanism 9 after passing through the corresponding channel 7, and can be reset under the action of elasticity.
[0020] The bracket 14 includes an annular sleeve 141 rotatably fitted at the end of the test box 3. The annular sleeve 141 is fixedly connected to a support plate 142 fixedly connected to the base 1 by multiple connecting rods. The support plate 142 has a working groove 143 for the transmission mechanism 10 and the kneading structure 12 to pass through.
[0021] This application involves conducting two separate tests before evaluation.
[0022] First, place the sample bag containing wool that meets the test requirements into the test chamber 3, and then place several clean rubber balls into the test chamber 3. Then close the test chamber 3, set the number of rotations of the test chamber 3 through the control device 2, and then start the control device 2 to drive the test chamber 3 to rotate. After the test chamber 3 has rotated the set number of times, the control device 2 stops working. Then take out the rubber balls from the test chamber 3 and carefully count the number of wool fibers on the rubber balls.
[0023] The sample bag is then tilted against the inner wall of the test chamber 3, opposite the baffle 6. The test chamber 3 is then closed. The linear movement mechanism 9 drives the telescopic device 11 and the rubbing structure 12 to move axially along the test chamber 3 via the transmission mechanism 10. This allows the rubbing structure 12 to enter the test chamber 3 and move the baffle 6 synchronously. Simultaneously, the rubbing structure 12 is driven by the telescopic device 11 to squeeze the sealing plate 8 to open the channel 7, allowing the rubbing structure 12 to pass through the baffle 6 and enter the test chamber 3. When the rubbing structure 12 comes into contact with the sample bag, the linear movement mechanism 9 stops working. The telescopic device 11 pushes the rubbing structure 12 back and forth, causing the rubbing structure 12 to continue to open under the thrust of the telescopic device 11 and the resistance of the sample bag. When the telescopic device 11 retracts, the rubbing structure 12 resets itself through its own elasticity, thus squeezing and rubbing the sample bag. After repeating this process several times, the telescopic device 11 stops working, the test chamber 3 is opened, the sample bag is taken out, and the number of wool fibers that have emerged from the test chamber 3 and the sample bag is carefully recorded. The product's wool-proof properties are evaluated based on the number of fibers.
[0024] By directly squeezing and kneading the sample bag through the kneading structure 12, the uncertainty of impacting the sample bag with a rubber ball in the prior art is avoided, and the accuracy of judging the anti-hair-drilling property is improved.
[0025] The positioning mechanism 13 is used to position the channel 7 on the baffle 6 so that the kneading structure 12 can accurately pass through the corresponding channel 7 and enter the test chamber 3.
[0026] In this embodiment, the control device 2, the linear motion mechanism 9, and the telescopic device 11 are all existing technologies. The control device 2 can drive the test box 3, the linear motion mechanism 9, the telescopic device 11, and the positioning mechanism 13 to work. The linear motion mechanism 9 can be a motor-driven screw rotation, and the telescopic device 11 can be an electric push rod or a hydraulic push rod, etc. The technical principles will not be elaborated in detail here.
[0027] In this embodiment, the test chamber 3 can be driven to rotate forward and backward by the control device 2, and the inner wall of the test chamber 3 is black to distinguish wool fibers.
[0028] The transmission mechanism 10 includes a transmission rod 101 slidably connected to the vertical plate 4, and the transmission rod 101 is connected to the linear movement mechanism 9 through a connecting seat. A connecting plate 102 is provided at the end of the transmission rod 101, and a connecting shaft 103 is fixedly connected to the connecting plate 102. The axis of the connecting shaft 103 coincides with the rotation center line of the test box 3. An intermediate plate 104 is fixedly connected to the end of the connecting shaft 103, and the intermediate plate 104 is rotatably connected to the baffle 6. The telescopic device 11 is mounted on the connecting shaft 103 through a mounting plate.
[0029] The linear movement mechanism 9 drives the connecting seat to move the transmission rod 101, and drives the connecting shaft 103 to move through the connecting plate 102, thereby driving the intermediate plate 104 to move, so that the intermediate plate 104 can drive the kneading structure 12 and the telescopic device 11 to enter or move away from the test box 3.
[0030] The intermediate plate 104 is rotatably connected to the baffle 6, so that the baffle 6 can rotate normally with the test box 3 and close the notch 5. After the relative position between the baffle 6 and the kneading structure 12 is determined by the positioning mechanism 13, the linear movement mechanism 9 drives the baffle 6 to move through the intermediate plate 104.
[0031] The kneading structure 12 includes multiple limiting frames 121 fixedly mounted on the middle plate 104 and pressure strips 122 connected to the ends of the telescopic device 11. Each limiting frame 121 is connected to the corresponding channel 7. Multiple pressure seats 123 are evenly spaced along the length of the pressure strip 122. Two connecting strips 124 are symmetrically rotatably connected to each pressure seat 123 by a torsion spring. Each end of the connecting strip 124 is rotatably connected to a pressure roller 126. Multiple passages 127 corresponding to the positions of the channels 7 are opened on the middle plate 104. When the connecting strip 124 is not extended into the test chamber 3, the two connecting strips 124 in the same limiting frame 121 abut against the inner wall of the limiting frame 121 by the elastic force of the torsion spring, and when the connecting strip 124 is extended into the test chamber 3, the two connecting strips 124 on the same pressure seat 123 open by the elastic force.
[0032] The limiting frame 121 includes two U-shaped plates 125 symmetrically arranged on the middle plate 104, and the openings of the two U-shaped plates 125 are opposite to each other.
[0033] When the kneading structure 12 moves under the drive of the telescopic device 11, the pressure roller 126 squeezes the corresponding sealing plate 8, causing the sealing plate 8 to open the channel 7. The two connecting strips 124 in the same limiting frame 121 slide along the limiting frame 121 through the passage 127 until they pass through the baffle 6 and enter the test box 3. At the same time, the pressure seat 123 closes the channel 7 to prevent the wool fibers in the test box 3 from detaching from the test box 3. The two connecting strips 124 on the same pressure seat 123 open under the elastic force of the torsion spring.
[0034] When the linear motion mechanism 9 drives the pressure roller 126 to move to contact the sample bag, the telescopic device 11 works again. When the telescopic device 11 extends, the two connecting strips 124 (referring to the connecting strips 124 on the same pressure seat 123) open under the resistance of the sample bag and the thrust of the telescopic device 11, and the pressure roller 126 rolls on the surface of the sample bag. When the telescopic device 11 shortens, the two connecting strips 124 (referring to the connecting strips 124 on the same pressure seat 123) reset under the elastic force of the torsion spring, and thus rotate in opposite directions. By repeatedly extending and shortening the telescopic device 11, the sample bag is directly and effectively squeezed and kneaded, avoiding the uncertainty of simulating squeezing and kneading with a rubber ball, and improving the accuracy of the evaluation results.
[0035] The pressure strip 122 is used to drive the pressure rollers 126 in multiple limiting frames 121 to simultaneously squeeze and knead the sample bag. The limiting frame 121 is composed of two U-shaped plates 125, that is, there is a gap between the two U-shaped plates 125 so that the pressure strip 122 can continue to move towards the middle plate 104 through the gap without interfering with the limiting frame 121.
[0036] Multiple pressure seats 123 on the two kneading structures 12 are misaligned with each other.
[0037] To avoid interference between the pressure rollers 126 on two adjacent kneading structures 12.
[0038] The positioning mechanism 13 includes a pushing device 131 disposed on the outer wall of the control device 2, a positioning rod 132 disposed on the movable end of the pushing device 131, and a fixing rod 133 disposed on the outer wall of the test box 3.
[0039] When it is necessary to align the channel 7 on the baffle 6 with the passageway 127 on the intermediate plate 104, the push device 131 is activated to drive the positioning rod 132 to extend into the movement path of the fixed rod 133. When the fixed rod 133 abuts against the positioning rod 132, the positions of the channel 7 and the passageway 127 correspond.
[0040] When the relative positions of channel 7 and passageway 127 are determined, the test box 3 is driven to rotate forward.
[0041] The present invention also provides a test method for an anti-hair-drilling test device, comprising the following steps: S100 Before testing, clean the fibers inside test chamber 3, wipe the six rubber balls to be used clean, place the rubber balls inside test chamber 3, and wipe the sample bag containing wool clean. S200, place the sample bag inside the test chamber 3, control the test chamber 3 to rotate through the control device 2, set the number of rotations to one thousand, start the control device 2, and the test chamber 3 will start to rotate; S300, after the test chamber 3 has rotated 1,000 revolutions, the rubber ball is taken out from the test chamber 3, and the wool fibers on the surface of the rubber ball and the wool fibers in the test chamber 3 are carefully counted. The sample bag is then adjusted to lean against the side wall of the test chamber 3 opposite to the baffle 6. The test chamber 3 is then closed, the linear movement mechanism 9 is started, and the kneading structure 12 is driven into the test chamber 3. At the same time, the telescopic device 11 drives the kneading structure 12 to squeeze the sealing plate 8 to rotate. When the kneading structure 12 squeezes the sample bag to fit against the inner side wall of the test chamber 3, the linear movement mechanism 9 is closed. S400, the telescopic device 11 is activated to extend and shorten, and the two connecting strips 124 on the same pressure seat 123 are opened and reset in a cyclical manner to rub the sample bag; S500, after the number of extensions and retractions of the telescopic device 11 is reached, the test box 3 is opened, the sample bag is taken out, and the wool fibers in the test box 3 are carefully counted, the data is recorded, and the test results are given after comparing the data with the judgment criteria.
[0042] During the test, the selected sample bags were two finished samples of 42cm*42cm cut from the finished product. The original two vertical seams were retained, and the original quilting lines were preserved as much as possible. The edges were rolled and sewn with binding fabric. The final sample bag size was (40±0.5)cm×(40±0.5)cm.
[0043] Use a heat gun to seal the laboratory seams and rolled edges of the sample bag, preserving the original finished product seams and surface seams.
[0044] Before testing, clean the wool fibers inside and outside the test chamber 3 and on the rubber ball.
[0045] When the test is conducted through a rubber ball, after the test is completed, the wool fibers inside and outside the test chamber 3 and on the rubber ball are carefully removed and the quantity is recorded. After being squeezed and rubbed by the rubbing structure 12 (the number of rubbing times is determined according to the test requirements, such as 500 times), the quantity of wool fibers inside and outside the test chamber 3, the rubbing structure 12, the sealing plate 8 and the baffle 6 are recorded again. The sample bag is then removed, both sides of the sample bag are checked, and the wool fibers that have emerged from the sample bag are removed one by one and counted.
[0046] For each wool fiber protruding from the fabric of the sample bag, count it as one fiber, regardless of the extent of protrusion. Wool fibers longer than 15 mm adhering to the rubber ball are also counted as one fiber. Then, gently and evenly wipe test chamber 3 with a cleaning cloth, counting once after wiping every 1-2 panels. Wipe all panels at least twice until completely clean. Wool fibers longer than 15 mm wiped out of test chamber 3 are counted as one fiber. Record the total number of wool fibers found in the sample bag, rubber ball, and test chamber 3. If the total number exceeds 100, record the result as "100+". If the original quilting thread of the sample bag comes loose during the test, the test is invalid and a new sample needs to be prepared. The arithmetic mean of the number of burrs in the two sample bags is taken as the final result, and it is rounded to the integer part according to GB / T 8170.
