Description

Technical Field

[0001] The present invention relates to the technical field of chemical property detection, and specifically to an automated chlorine resistance performance test system and method based on spandex filaments. Background Art

[0002] Spandex filaments are generally made into clothing and other items as fabric materials. When clothes and the like are used in daily life, they will come into contact with chlorine-containing liquids, and corrosion will gradually occur after long-term use. Therefore, existing spandex filaments need to be tested for chlorine resistance performance after production.

[0003] For example, Chinese Patent CN210894038U discloses a chlorine resistance performance test device for spandex filaments in the clothing industry. By hanging a heavy iron ring at one end of the spandex filament to be tested in the test water, the chlorine resistance time of the spandex filament can be effectively detected, providing an effective reference for the application of spandex filaments in the clothing industry, and it can also save labor operation costs and achieve industrial automation.

[0004] However, this device can only test one spandex filament at a time. If multiple specifications of spandex filaments need to be detected simultaneously, heavy iron rings need to be hung separately, which is cumbersome and inefficient. Moreover, one spandex filament can only detect a solution of one concentration. If solutions of different concentrations need to be detected, multiple detections are required, which is even more troublesome, consumes more spandex filaments, and has a longer detection cycle. Summary of the Invention

[0015] The present invention also discloses a test method for an automated chlorine resistance performance test system based on spandex filaments, which is characterized in that it specifically includes the following steps:

[0016] Step 1: Pour detection solutions with different concentrations into different cavities of the detection box. Then open the flip cover, place the winding rollers with different spandex filaments wound on the surface on the bracket, pull out one end of the spandex filament and place it on the right side of the top of the detection box, and then cover the flip cover.

[0017] Step 2: Start the air pump to inflate the aeration pipe through the second air charging pipe, thereby aerating the solution in the detection box to further mix the solution evenly inside. Then switch the three-way valve, and discharge the air discharged by the air pump into the blowing hood through the first air charging pipe to make it blow to the left. The air flow blows the blades at both ends of the winding roller to drive its rotation, releases the spandex filament on its surface, and at the same time the air flow blows the released spandex filament to the left until a section extends out from the left side of the detection box, and then turn off the air pump.

[0020] Step 5: Continue to shake the crank to make the winch completely loosen the lifting rope. At this time, the weight only presses the spandex filament under the action of gravity, and makes the spandex filament soak in the solution. At the same time, start the control panel to time, record the maintenance time of the corresponding spandex filament when it is observed that a spandex filament breaks, and finally list and compare all the spandex filaments and different concentration data.

[0021] Preferably, the top cover can be suspended by a suspension device, or the top cover can be supported by sleeving a support sleeve outside the positioning block.

[0022] Beneficial effects

[0023] The present invention provides an automated chlorine resistance performance test system and method based on spandex filaments. Compared with the prior art, it has the following beneficial effects:

[0024] (1) The automated chlorine resistance performance testing system and method based on spandex can store detection solutions with different concentrations in multiple cavities inside the detection box, enabling the chlorine resistance performance testing of spandex at different concentrations. Moreover, multiple spandex filaments of different specifications can be detected simultaneously, effectively improving the efficiency. By using the pressing strips at the bottom of the top cover in cooperation with the first rubber sleeve at the top of the detection box, the spandex filaments can be pressed in multiple segments, and then the pressing components are used to apply pressure respectively, so that the spandex filaments can be detected with multiple strengths simultaneously, and there is no interference between each segment. All the weights applying gravity can also be uniformly controlled, which is convenient to use.

[0025] (2) The automated chlorine resistance performance testing system and method based on spandex lead out two charging pipes from the output end of the air pump. One charges the blowing hood so that it can blow air to the left, directly blowing the spandex filaments to the left side of the detection box and can traction multiple filaments simultaneously, saving the cumbersome manual traction; while the other charging pipe can charge the aeration pipe, and aeration can be carried out after adding the solution to make the liquid medicine and water in it mix more evenly. The air flow direction can be switched only by changing the three-way valve, which is convenient to use.

[0026] (3) The automated chlorine resistance performance testing system and method based on spandex set multiple partition plates outside the central shaft of the winding roller to separate multiple positions, enabling the winding of spandex filaments of different specifications for detection. By setting a structure similar to an impeller at both ends of the winding roller, when the air flow blows towards the winding roller, on the one hand, it can drive the winding roller to rotate to release the spandex filaments, and on the other hand, it can blow the spandex filaments to the left. The bearing seats set at both ends of the winding roller can also ensure the flexible rotation of the winding roller, which is convenient to use.

[0027] (4) The automated chlorine resistance performance testing system and method based on spandex set a drain pipe at the bottom that can communicate with multiple cavities simultaneously, and a plugging block that can block the corresponding communication ports is arranged inside the drain pipe. During normal operation, the solutions with different concentrations in multiple cavities will not be mixed with each other. When the plugging block is pulled out, the solutions in all cavities can be drained together without opening them one by one, which is convenient to use. Description of the Drawings

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0041] The present invention provides four technical solutions:

[0042] Figures 1-8The first embodiment is shown: an automated chlorine resistance testing system based on spandex yarn, comprising a test box 1 and a top cover 2 arranged on the top thereof, the interior of the test box 1 being divided into a plurality of cavities by a plurality of vertical plates 101, and test solutions of different concentrations being poured into different cavities, the left and right sides of the top of the test box 1 and the top of the vertical plate 101 being fixedly sleeved with a first rubber sleeve 102, the front and rear sides of the top right side of the test box 1 being fixedly connected with a bracket 3, and a winding roller 4 for winding different types of spandex yarns is placed between the two brackets 3.

[0043] A glass observation window 103 is fixedly connected to the front of the detection box 1 and the front side of each cavity, a liquid filling port with a sealing cover is provided on the front side of the top of the top cover 2 and above each cavity, a control panel 104 is fixedly connected to the back of the detection box 1, positioning blocks 105 are fixedly connected to the tops of the front and rear sides of the detection box 1, and a positioning groove matched with the positioning block 105 is provided at the bottom of the top cover 2.

[0044] A compression strip 201 with a corrugated bottom is fixedly connected to the top of the inner surface of the top cover 2 corresponding to the position of the first rubber sleeve 102. The corrugated bottom can increase the resistance to prevent the spandex thread from sliding. The top cover 2 is connected to the front and rear sides of the detection box 1 by a buckle 5. A blowing hood 6 for blowing air to the left is fixedly connected to the right side of the top cover 2 and located to the upper right of the winding roller 4. A pressure component 7 for pressing the spandex thread downward by gravity is provided on the top of the top cover 2.

[0045] The pressure-applying assembly 7 includes a plurality of parallel rotating shafts 71 and a plurality of winches 72 corresponding to the cavities fixedly connected on the surface thereof, and a suspension rope 73 is wound around the surface of the winch 72, and a pendant 74 is bound to the movable end of the suspension rope 73. The pendant 74 includes two counterweight balls 741, and the counterweight balls 741 are fixedly connected by an A-shaped frame 742.

[0046] The left end of the front rotating shaft 71 is fixedly connected with a crank handle 75, and the multiple rotating shafts 71 are meshed and transmitted through gears 76. The rotating shaft 71 is mounted on the top of the top cover 2 through a protective shell 77 mounted on the winch 72 and the outside. Two supporting ribs 78 are fixedly connected on both sides of the protective shell 77. The bottom end of the crank handle 75 is rotatably connected with a short handle 79, and the short handle 79 can be stuck between the two supporting ribs 78 on the corresponding side when it droops naturally.

[0047] By arranging a plurality of cavities in the detection box 1 to store detection solutions of different concentrations, the chlorine resistance of the spandex yarn can be tested at different concentrations, and a plurality of spandex yarns of different specifications can be tested at the same time, which effectively improves the efficiency. The spandex yarn can be divided into multiple sections and compressed by using the compression strip 201 at the bottom of the top cover 2 in cooperation with the first rubber sleeve 102 at the top of the detection box 1, and then the pressure component 7 is used to apply pressure respectively, so that the spandex yarn can be tested with multiple strengths at the same time, and each section does not interfere with each other. All the weight-applying pendants 74 can also be controlled in a unified manner, which is convenient to use.

[0048] Figures 1-3 The second embodiment is shown. The main difference from the first embodiment is that an inflation component 8 is provided on the right side of the detection box 1. The inflation component 8 includes an air pump 81 fixedly connected to the right wall of the detection box 1. A filter mesh cover is fixedly connected to the input end of the air pump 81. The output end of the air pump 81 is fixedly connected to a first inflation pipe 82 and a second inflation pipe 83 through a three-way valve. And the top end of the first inflation pipe 82 is communicated with the bottom of the blowing hood 6.

[0049] At the bottom of multiple cavities inside the detection box 1, air distribution pipes 84 are fixedly connected. One end of the air distribution pipe 84 extends to the top of the rear side of the detection box 1, and the top ends of the air distribution pipes 84 are all communicated with the surface of the second inflation pipe 83.

[0050] By leading out two inflation pipes from the output end of the air pump 81, one inflates the blowing hood 6 so that it can blow air to the left, directly blowing the spandex filaments to the left side of the detection box 1, and multiple filaments can be pulled at the same time, saving the trouble of manual traction; and the other inflation pipe can inflate the air distribution pipes 84, and aeration can be carried out after adding the solution, making the liquid medicine and water in it mix more evenly. The air flow direction can be switched only by changing the three-way valve, which is convenient to use.

[0051] Figures 1-3 Figures 8 and 9 show the third embodiment. The main difference from the second embodiment is that a flip cover 202 is hinged on the right side of the top cover 2 and above the winding roller 4. Setting the flip cover 202 facilitates the placement of the winding roller 4, and it does not affect the air flow to the left after being covered. When taking out the winding roller 4, it can be pushed out from the bottom of the winding roller 4 upwards. The winding roller 4 includes a central shaft 41 and a plurality of partition plates 42 fixedly connected to its surface. Two layers of discs 43 are fixedly connected to the surfaces at both ends of the central shaft 41, and a plurality of blades 44 are radially fixedly connected between the two discs 43 at the same end. The blowing range of the blowing hood 6 needs to cover the position of the blades 44. Bearing seats 45 that can be mounted inside the bracket 3 are rotatably sleeved at both ends of the central shaft 41. A U-shaped groove for placing the bearing seats 45 is opened at the top of the bracket 3, and the surface of the U-shaped groove is covered with a second rubber sleeve. The second rubber sleeve is provided for buffering when the winding roller 4 is placed.

[0052] By providing a plurality of partition plates 42 outside the central shaft 41 of the winding roller 4 to separate multiple positions, spandex filaments of different specifications can be wound for detection. And by providing a structure similar to an impeller at both ends of the winding roller 4, when the air flow blows towards the winding roller 4, on the one hand, it can drive the winding roller 4 to rotate to release the spandex filaments, and on the other hand, it can blow the spandex filaments to the left. The bearing seats 45 provided at both ends of the winding roller 4 can also ensure the flexible rotation of the winding roller 4, which is convenient to use.

[0053] Figures 1-3Figs. 10 - 11 show the fourth embodiment. The main difference from the third embodiment is that a drain pipe 9 is fixedly connected to the bottom of the detection box 1, and communication ports 91 communicating with multiple cavities respectively are formed at the top of the drain pipe 9. A connecting rod 92 is arranged inside the drain pipe 9, and a blocking block 93 corresponding to multiple communication ports 91 is rotatably connected to the surface of the connecting rod 92. The blocking block 93 can only rotate on the surface of the connecting rod 92 and cannot slide. A threaded cover 94 that can be threadedly sleeved on the outer part of the left end of the drain pipe 9 is fixedly connected to the left end of the connecting rod 92. A notch is formed at the bottom of the blocking block 93 for allowing the solution to flow from below. Limiting strips 95 are fixedly connected to both the front and rear sides of the inner wall of the drain pipe 9, and sliding grooves 96 adapted to the limiting strips 95 are formed on both sides of the blocking block 93.

[0054] By arranging the drain pipe 9 at the bottom that can communicate with multiple cavities simultaneously, and arranging the blocking block 93 in the drain pipe 9 that can block the corresponding communication ports 91, the solutions with different concentrations in multiple cavities will not be mixed with each other during normal operation. When the blocking block 93 is pulled open, the solutions in all cavities can be discharged together without opening them one by one, which is convenient to use.

[0055] The present invention also discloses a test method for an automatic chlorine resistance performance test system based on spandex filaments, which is characterized in that it specifically includes the following steps:

[0056] Step 1: Pour detection solutions with different concentrations into different cavities of the detection box 1. Then open the flip cover 202, place the winding rollers 4 with different spandex filaments wound on their surfaces on the bracket 3, pull out one end of the spandex filament and place it on the right side of the top of the detection box 1, and then cover the flip cover 202.

[0057] Step 2: Start the air pump 81 to inflate the aeration pipe 84 through the second inflation pipe 83, thereby aerating the solution in the detection box 1 to further mix the solution evenly inside. Then switch the three-way valve, and discharge the air discharged by the air pump 81 into the air blowing hood 6 through the first inflation pipe 82 to make it blow to the left. The air flow blows the blades 44 at both ends of the winding roller 4 to drive it to rotate, release the spandex filament on its surface. At the same time, the air flow blows the released spandex filament to the left until a section extends from the left side of the detection box 1, and then turn off the air pump 81.

[0058] Step 3: Flatten the short handle 79 of the crank 75, then shake the crank 75 to drive the rotating shaft 71 to rotate, drive other rotating shafts 71 to rotate together by the engagement of the gears 76, and make the winch 72 loosen the suspension rope 73, and slowly lower the weight 74 by a section and put it on the outside of the spandex filament.

[0059] Step 4: Put down the top cover 2 to make the weight 74 synchronously drop by a section, press down and bend the spandex filament, and at the same time make the pressing strip 201 at the bottom of the top cover 2 press the spandex filament tightly on the first rubber sleeve 102.

[0060] Step 5: Continue to turn the crank 75 to completely loosen the lifting rope 73 of the winch 72. At this time, the falling object 74 presses down the spandex only under the action of gravity, and immerses the spandex in the solution. At the same time, start the control panel 104 to time. When observing that a spandex breaks, record the maintenance time of the corresponding spandex. Finally, list and compare all the spandex and different concentration data.

[0061] The top cover 2 can be suspended by a suspension device or supported by a support sleeve outside the positioning block 105.

[0062] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

Liquid injection ports with sealing covers are formed at the front of the top of the top cover (2) and above each cavity. A control panel (104) is fixedly connected to the back of the detection box (1). Positioning blocks (105) are fixedly connected to the tops of the front and rear sides of the detection box (1), and positioning grooves adapted to the positioning blocks (105) are formed at the bottom of the top cover (2).

5. A testing method for the automatic chlorine resistance performance testing system based on spandex according to claim 4, characterized in that: Specifically, it includes the following steps: Step 1: Pour detection solutions with different concentrations into different cavities of the detection box (1). Then open the flip cover (202), place the winding roller (4) with different spandex wound on its surface on the bracket (3), pull out one end of the spandex and place it on the right side of the top of the detection box (1), and then cover the flip cover (202); Step 2: Start the air pump (81) to inflate the aeration pipe (84) through the second air charging pipe (83), thereby aerating the solution in the detection box (1) to further mix the solution therein evenly. Then, switch the three-way valve to discharge the air exhausted by the air pump (81) into the blowing hood (6) through the first air charging pipe (82), so that it blows to the left. The airflow blows the blades (44) at both ends of the winding roller (4) to drive its rotation, releases the spandex on its surface. At the same time, the airflow blows the released spandex to the left until a section extends out from the left side of the detection box (1), and then turn off the air pump (81); Step 3: Flatten the short handle (79) of the crank (75), and then turn the crank (75) to drive the rotation of the rotating shaft (71). Drive the rotation of other rotating shafts (71) together by the meshing of the gears (76), and make the winch (72) loosen the suspension rope (73), and slowly lower the weight (74) by a section and put it on the outside of the spandex; Step 4: Lower the top cover (2) so that the weight (74) synchronously drops by a section, press down and bend the spandex, and at the same time, the pressing strip (201) at the bottom of the top cover (2) presses the spandex tightly on the first rubber sleeve (102); Step 5: Continue to turn the crank (75) to completely loosen the suspension rope (73) by the winch (72). At this time, the weight (74) presses the spandex under the action of gravity only, and makes the spandex soak in the solution. At the same time, start the control panel (104) to time, record the maintenance time of the corresponding spandex when observing that the spandex breaks, and finally list and compare all the spandex and different concentration data.

6. The test method of an automated chlorine resistance performance test system based on spandex according to claim 5, characterized in that: the top cover (2) can be suspended by a suspension device, or the top cover (2) can be supported by sleeving a support sleeve on the positioning block (105).
