Abstract

The present application relates to the technical field of acid and alkali resistance detection of fabrics, and particularly relates to acid and alkali resistance detection equipment for textile production. The acid and alkali resistance detection equipment comprises a detection platform, a winding type soaking mechanism arranged above the detection platform, and a soaking barrel arranged at the top center of the detection platform. The two groups of winding columns are controlled to drive the textile sample to separate from the soaking barrel, and meanwhile, the two groups of winding columns are controlled to drive the textile to move upwards and abut against the bottom of the fixed plate, so that the internal space of the sample is closed, and then hot air is introduced into the internal space of the sample. Since the sample absorbs the solution, the moisture absorbed in the sample can be quickly discharged and dried under the action of the internal and external air pressure difference. Meanwhile, the sample wound for multiple turns can detect the acid and alkali solution resistance of the textile by detecting the corrosion changes of different regions of the sample, thereby improving the working efficiency of the detection equipment and the detection effect.

Description

[0001] This application is a divisional application of the application filed on May 14, 2025, with application number 2025106196502 and invention title "An acid and alkali resistance testing device and testing method for textile production". Technical Field

[0002] This invention belongs to the field of acid and alkali resistance testing technology for fabrics, and specifically relates to an acid and alkali resistance testing device for textile production. Background Technology

[0003] Fabrics refer to flat, soft sheets or blocks of material made by crossing, knotting, and connecting small, flexible pieces of material. Before leaving the factory, fabrics need to undergo acid and alkali resistance testing. In order to prevent harm to the human body during the acid and alkali resistance testing process, an acid and alkali resistance testing machine is usually used.

[0004] A search revealed that Chinese Patent Publication No. CN117871380B, published on August 2, 2024, discloses a textile acid and alkali resistance testing machine. The machine includes a body, which comprises a casing. Both sides of the back of the casing are hinged to sealing doors. A handle is fixedly connected to the back of each sealing door, and a sealing gasket is fixedly connected to the front. This textile acid and alkali resistance testing machine, by pushing a baffle plate to rotate, causes a movable seat to rotate, which in turn causes a first screw to rotate within the cavity of a fixed seat until the baffle plate changes from horizontal to vertical. This prevents acid and alkali solutions from dripping around the equipment during fabric movement, solving the problem in existing acid and alkali resistance testing machines where, due to the lack of a baffle mechanism, acid and alkali solutions adhering to the fabric surface drip around the equipment, affecting the surrounding environment and the equipment itself.

[0026] To detect corrosion in different areas of textile samples;

[0027] Complete the acid and alkali resistance testing of textiles.

[0028] The beneficial effects of this invention are:

[0029] 1. By controlling two sets of winding columns to lift the textile sample out of the soaking tank, and simultaneously controlling the two sets of winding columns to move the textile upwards and abut against the bottom of the fixed plate, several sets of magnetic sealing plates break free from the magnetic field restriction between the two sets of magnetic plates, rotate and reset, and reseal several sets of water passage holes, thus sealing the internal space of the sample. Then, hot air is introduced into the internal space of the sample. Since the sample has absorbed the solution, the absorbed water in the sample can be quickly discharged and dried under the action of the pressure difference between the inside and outside of the air. At the same time, the sample with multiple windings can be tested to detect the anti-seepage performance of textiles against acid and alkali solutions by detecting the corrosion changes in different areas of the sample. This improves both the working efficiency of the testing equipment and the testing effect.

[0030] 2. By passing one end of the textile sample through the tension column and two sets of pinch rollers, and then leading it out between two sets of guide plates, the two sets of pinch rollers are controlled to cooperate with the fabric take-up roller to feed the textile sample out. The spacing between the two sets of pinch rollers can be adjusted arbitrarily according to the thickness of the textile. At the same time, the tension column can tighten the textile sample in real time under the action of elasticity, so that the light emitted by the light strip can be received by the light sensor after passing through the textile sample, which facilitates the detection of defects such as damage to the textile sample. This improves the compatibility of the detection equipment and the feeding effect.

[0031] 3. By inputting the appropriate volume of acidic or alkaline solution and pure water into the mixing chamber, and under real-time monitoring by an acid / alkalinity detector and a detection probe, solutions with the appropriate pH values ​​can be prepared according to the acid and alkali resistance testing requirements. Furthermore, after the soaking process is completed, the acidic or alkaline solution can be recycled back into the mixing chamber. When using the corresponding acidic or alkaline solutions for testing, the solution can be heated by a heating plate for distillation and purification, and the acidic or alkaline solution can be recycled back into the corresponding storage tank, thereby reducing production costs.

[0032] 4. After the testing is completed, control the fixed plate to descend and contact the top of the soaking tank. Then, control the hot air gun to start and spray hot air to quickly dry the inside of the soaking tank. The steam can be discharged through the single pipe, which avoids the problem of residual moisture and dust in the soaking tank easily entering the soaking tank. At the same time, the winding soaking mechanism can be stored in a closed space, which improves the service life of the testing equipment.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0046] This invention provides an acid and alkali resistance testing device for textile production, including a testing platform 1. For example, as shown... Figure 1 and Figure 2 As shown, two sets of maintenance doors 2 are symmetrically arranged on one side wall of the testing platform 1; a mounting column 3 is located on one side edge of the top of the testing platform 1; a lifting column 4 is located inside the mounting column 3; a mounting plate 5 is located on the top of the lifting column 4; a first motor 6 is located at the bottom of the end of the mounting plate 5 away from the lifting column 4; a winding soaking mechanism 7 is connected to the output end of the first motor 6; a soaking tank 8 is located at the center of the top of the testing platform 1; and a sample loading mechanism 9 is located at one side edge of the top of the testing platform 1.

[0047] Specifically, the testing platform 1 is equipped with a storage chamber 10; the bottom of the soaking tank 8 extends into the storage chamber 10; a single-pass pipe is provided on the top wall of the soaking tank 8 away from the maintenance door 2; the end of the single-pass pipe away from the soaking tank 8 extends to the outside of the testing platform 1; three sets of storage tanks 11 are provided at one edge of the bottom of the storage chamber 10; the three sets of storage tanks 11 respectively store pure water, alkaline solution and acidic solution; three sets of metering pumps 12 are provided at the bottom of the storage chamber 10; a recovery tank 13 is provided at the bottom of the storage chamber 10; an acid-base mixing mechanism 14 is provided in the storage chamber 10; a set of two-way valves 15 are provided on the bottom and one side wall of the soaking tank 8; two sets of magnetic plates 16 are symmetrically provided on one inner wall of the storage chamber 10; the two sets of magnetic plates 16 are located on both sides of the soaking tank 8.

[0048] When conducting acid and alkali resistance testing on textiles, a textile sample of the appropriate length is first placed on the sample loading mechanism 9. Then, a quantitative pump 12 is used to quantitatively deliver pure water and alkaline or acidic solutions to the acid-alkali mixing mechanism 14 according to the testing requirements. After adjusting the solution to the corresponding pH value, it is delivered to the soaking tank 8. Subsequently, the winding soaking mechanism 7 is controlled to clamp one end of the textile sample on the sample loading mechanism 9. Then, the first motor 6 is controlled to drive the winding soaking mechanism 7 to rotate and wrap the textile sample to the appropriate length.

[0049] Specifically, the sample loading mechanism 9 is then controlled to cut the textile sample. After the textile sample is completely fixed in the winding soaking mechanism 7, the lifting column 4 is controlled to descend into the soaking tank 8 in the winding soaking mechanism 7, so that the textile sample is completely immersed in the acid and alkali solution. After the appropriate soaking time, the acid and alkali solution in the soaking tank 8 is discharged into the acid and alkali mixing mechanism 14. Then, pure water is introduced into the soaking tank 8 so that the textile sample is immersed in pure water to avoid the residual acid and alkali solution on the sample from causing harm to the testing personnel. Then, the winding soaking mechanism 7 lifts the textile sample. After the textile sample is dried, the staff removes the textile sample and proceeds to the next step of the testing.

[0050] For example, such as Figure 3 , Figure 4 and Figure 5As shown, the winding soaking mechanism 7 includes a fixed plate 701; two sets of winding columns 702 are symmetrically and movably passed through the bottom of the fixed plate 701; a hot air gun 703 is provided on the top of the fixed plate 701; a control box 704 is provided on the top of the fixed plate 701; a lifting plate 705 is slidably connected in the vertical direction inside the control box 704; a second motor 706 is provided on the top of the control box 704; a lead screw 707 is drivenly connected to the output end of the second motor 706; the lead screw 707 is threadedly connected to the lifting plate 705; the top of one set of winding columns 702 movably passes through the control box 704 and is drivenly connected to the bottom of the lifting plate 705.

[0051] Specifically, the bottom of the two sets of winding columns 702 is provided with fabric baffles 708; the top of the fabric baffles 708 is provided with several sets of water holes 709 arranged in a rectangular array; several sets of grooves 710 are equally spaced on the outer wall of each set of winding columns 702; a set of magnetic clamps 711 are elastically rotatably connected in each set of grooves 710; a set of electromagnets 712 are provided on the inner wall of each set of grooves 710; two sets of through slots 713 are symmetrically opened on the two sides of the top of the fabric baffles 708; a set of fabric clips 714 are provided in each set of through slots 713.

[0052] Specifically, the bottom center of the fixed plate 701 is provided with several sets of air jet holes 715 evenly distributed; each set of air jet holes 715 is connected to the output end of the hot air gun 703; the bottom of the fabric baffle 708 is provided with several sets of rotating grooves 716 at equal intervals; each set of rotating grooves 716 is rotatably connected to a set of magnetic sealing plates 717; each set of magnetic sealing plates 717 is provided with a set of torsion springs on its rotating shaft; each set of magnetic sealing plates 717 is movably sealed to several sets of corresponding water passage holes 709.

[0053] When conducting acid and alkali resistance testing on textiles, the electromagnets 712 on a corresponding set of winding columns 702 are energized. Since the electromagnets 712 and the corresponding magnetic clamps 711 have different magnetic properties on opposite sides, one end of the magnetic clamps 711 rotates and disengages from the groove 710, thereby enabling the sample loading mechanism 9 to transport one end of the textile sample between the corresponding sets of magnetic clamps 711 and the winding columns 702. Subsequently, the electromagnets 712 are de-energized and demagnetized, causing the magnetic clamps 711 to reset and clamp one end of the textile sample.

[0054] Specifically, the fixing plate 701 then drives the two sets of winding columns 702 to rotate and wind the textile sample onto the two sets of winding columns 702. After winding the sample to the corresponding length, the two tissue clips 714 are controlled to fix the textile sample and the sample loading mechanism 9 is controlled to cut the textile sample. Then, the two sets of winding columns 702 are controlled to drive the textile sample into the soaking tank 8 for soaking. When several sets of magnetic sealing plates 717 reach between the two sets of magnetic plates 16, they rotate 90 degrees under the action of the magnetic field between the two sets of magnetic plates 16, so that several sets of water holes 709 open, so that acid and alkali solutions can quickly enter the textile sample ring.

[0055] Specifically, after the soaking process is completed, the two sets of winding columns 702 are controlled to lift the textile sample out of the soaking tank 8. At the same time, the second motor 706 is controlled to drive the lead screw 707 to rotate. With the threaded connection between the lead screw 707 and the lifting plate 705, the lifting plate 705 moves the textile sample upward through the corresponding set of winding columns 702 and abuts against the bottom of the fixed plate 701. Meanwhile, several sets of magnetic sealing plates 717 can be reset after disengaging from the two sets of magnetic plates 16 and re-seal several sets of water holes 709, thus sealing the internal space of the textile sample. Then, the hot air gun 703 is controlled to spray hot air through several sets of air jet holes 715. Under the action of air pressure, the water absorbed in the textile sample can be quickly discharged and dried. At the same time, by wrapping the textile sample multiple times, the corrosion changes in different areas of the textile sample can be observed to detect the anti-seepage performance of the textile against acid and alkali solutions. This improves both the working efficiency of the testing equipment and the testing effect.

[0056] Specifically, after the testing is completed, the control plate 701 is lowered and abuts against the top of the soaking tank 8. Then, the control hot air gun 703 is activated to spray hot air to quickly dry the inside of the soaking tank 8. The steam can be discharged through the single-pass pipe, which avoids the problem of residual moisture and dust in the soaking tank 8 easily entering the soaking tank 8. At the same time, the winding soaking mechanism 7 can be stored in a closed space, which improves the service life of the testing equipment.

[0057] For example, such as Figure 6 and Figure 7 As shown, the sample loading mechanism 9 includes two sets of first support plates 901 symmetrically arranged in the vertical direction; several sets of support columns 902 are provided between the two sets of first support plates 901; a third motor 903 is provided at the top edge of the lower first support plate 901; a fabric take-up roller 904 is driven to the output end of the third motor 903; a tensioning column 905 is provided at the top edge of the lower first support plate 901; and a light source strip 906 and a light sensor 907 are provided between the two sets of first support plates 901.

[0058] Specifically, the light source strip 906 and the light sensor 907 are respectively disposed on both sides of the vertical plane formed by the central axis of the fabric take-up roller 904 and the tensioning column 905; a set of second support plates 908 are respectively provided on the opposite side of the two sets of first support plates 901; two sets of pinch rollers 909 are symmetrically arranged between the two sets of second support plates 908; two sets of fourth motors 911 are symmetrically arranged on the opposite side of the two sets of second support plates 908; the output end of each set of fourth motors 911 is connected to the corresponding set of pinch rollers 909; two sets of guide plates 910 are provided between the two sets of first support plates 901; the cross-section of each set of guide plates 910 is fan-shaped.

[0059] When conducting acid and alkali resistance testing of textiles, the third motor 903 drives the fabric winding roller 904 to wind and wind the textile sample. Then, one end of the textile sample is pulled and, after passing around the tensioning column 905, it enters between the two sets of clamping rollers 909, and then is pulled between the two sets of guide plates 910.

[0060] Specifically, during the sample loading process, the two sets of pinch rollers 909 work in conjunction with the fabric take-up roller 904 to feed the textile sample out. The spacing between the two sets of pinch rollers 909 can be adjusted arbitrarily according to the thickness of the textile. At the same time, the tensioning column 905 can tighten the textile sample in real time under the action of elasticity, so that the light emitted by the light source strip 906 can be received by the light sensor 907 after passing through the textile sample. This facilitates the detection of defects such as damage to the textile sample, improving both the compatibility of the detection equipment and the loading effect.

[0061] For example, such as Figure 8 and Figure 9 As shown, the acid-base mixing mechanism 14 includes a mixing tank 1401; a delivery pump 1402 is provided on the top of the mixing tank 1401; an acid-base detector 1403 is provided on the top of the mixing tank 1401; a mixing chamber 1405 is provided inside the mixing tank 1401; a suction tube 1406 and a detection probe 1407 are provided inside the mixing chamber 1405; the suction tube 1406 and the detection probe 1407 are both embedded in the inner wall of the corresponding side of the mixing chamber 1405; the suction tube 1406 is connected to the delivery pump 1402; the detection probe 1407 is electrically connected to the acid-base detector 1403.

[0062] Specifically, a plurality of heating plates 1408 are evenly spaced on the bottom inner wall of the mixing chamber 1405; a scraper 1409 is slidably connected in the horizontal direction inside the mixing chamber 1405; the bottom of the scraper 1409 movably abuts against the bottom inner wall of the mixing chamber 1405; a plurality of through holes 1410 are evenly distributed on the scraper 1409; a plurality of connecting rods 1411 are provided on one side wall of the scraper 1409; a movable sealing plate 1404 is provided at one end of the plurality of connecting rods 1411 away from the scraper 1409; the movable sealing plate 1404 movably extends to the outside of the mixing box 1401.

[0063] When conducting acid and alkali resistance testing on textiles, by inputting the appropriate volume of acidic or alkaline solution and pure water into the mixing chamber 1405, and under real-time monitoring by the pH meter 1403 and the detection probe 1407, a solution with the appropriate pH value can be prepared according to the acid and alkali resistance testing requirements. After the soaking process is completed, the acidic or alkaline solution can be recycled back into the mixing chamber 1405. Furthermore, when using the corresponding acidic or alkaline solution for testing, the solution can be heated by the heating plate 1408 for distillation and purification, and the acidic or alkaline solution can be recycled back into the corresponding storage tank 11, thereby reducing production costs.

[0064] By controlling two sets of winding columns 702 to lift the textile sample out of the soaking tank 8, and simultaneously controlling the two sets of winding columns 702 to move the textile upward and abut against the bottom of the fixing plate 701, several sets of magnetic sealing plates 717 are released from the magnetic field restriction between the two sets of magnetic plates 16, rotate and reset, and re-seal several sets of water passage holes 709, thus sealing the internal space of the sample. Then, hot air is introduced into the internal space of the sample. Since the sample has absorbed solution, under the action of the pressure difference between the inside and outside of the sample, the absorbed water can be quickly discharged and dried. At the same time, the sample with multiple windings can be tested to detect the anti-seepage performance of textiles against acid and alkali solutions by detecting the corrosion changes in different areas of the sample. This improves the working efficiency of the testing equipment and the testing effect.

[0065] By passing one end of the textile sample between the tensioning column 905 and the two sets of pinch rollers 909, and then leading it out between the two sets of guide plates 910, the two sets of pinch rollers 909 are controlled to cooperate with the fabric take-up roller 904 to feed the textile sample out. The spacing between the two sets of pinch rollers 909 can be adjusted arbitrarily according to the thickness of the textile. At the same time, the tensioning column 905 can tighten the textile sample in real time under the action of elasticity, so that the light source emitted by the light strip 906 can be received by the light sensor 907 after passing through the textile sample, which facilitates the detection of defects such as damage to the textile sample. This improves the compatibility of the detection equipment and the feeding effect.

[0066] By inputting the appropriate volume of acidic or alkaline solution and pure water into the mixing chamber 1405, and under the real-time monitoring of the pH meter 1403 and the detection probe 1407, a solution with the appropriate pH value can be prepared according to the acid and alkali resistance testing requirements. At the same time, after the soaking work is completed, the acidic or alkaline solution can be recycled back into the mixing chamber 1405. Furthermore, when using the corresponding acidic and alkaline solutions for testing, the solution can be heated by the heating plate 1408 for distillation and purification, and the acidic or alkaline solution can be recycled back into the corresponding storage tank 11, thereby reducing production costs.

[0067] After the testing is completed, the control plate 701 is lowered and abuts against the top of the soaking tank 8. Then, the control hot air gun 703 is activated to spray hot air to quickly dry the inside of the soaking tank 8. The steam can be discharged through the single-pass pipe, which avoids the problem of residual moisture and dust in the soaking tank 8 easily entering the soaking tank 8. At the same time, the winding soaking mechanism 7 can be stored in a closed space, which improves the service life of the testing equipment.

[0068] Based on the aforementioned acid and alkali resistance testing equipment for textile production, this invention also proposes a testing method for the acid and alkali resistance testing equipment for textile production. For example, the testing method includes:

[0069] Control the rotation of two sets of winding rollers to wind textile samples of the corresponding length from the sample loading mechanism;

[0070] Two sets of winding rollers are controlled to lower the textile sample into the soaking tank for immersion in acid and alkali solutions.

[0071] Drain the acid and alkali solutions from the soaking tank and add the corresponding volume of pure water;

[0072] Two sets of winding rollers are controlled to move the textile sample upward after it has been soaked in pure water, and at the same time, it comes into contact with the bottom of the fixed plate while leaving the soaking tank;

[0073] Several sets of magnetic sealing plates were reset and re-blocked several sets of water passage holes;

[0074] Hot air is passed through the inside of the textile sample for rapid drying.
