Abstract

This invention provides an acid and alkali resistance testing device for textile fabric production, relating to the field of fabric acid and alkali resistance testing technology. It includes: a testing soaking tank; a top cover rotatably connected to the top of the testing soaking tank, forming a closed tank structure with the top cover; a rotating main shaft connected inside the testing soaking tank, with two fabric clamping frames fixedly connected to the outside of the rotating main shaft; and a movable slide connected to the outside of the rotating main shaft. This invention, through a rotational switching method, circulates the textile fabric repeatedly in acid and alkali solutions and air, causing the residual acid and alkali on the fabric surface to undergo secondary reactions with oxygen and carbon dioxide in the air, exposing weaknesses that cannot be detected by soaking tests alone.

Description

Technical Field

[0001] This invention relates to the field of acid and alkali resistance testing technology for fabrics, and more particularly to an acid and alkali resistance testing device for textile fabric production. Background Technology

[0002] In the production and application of textiles, acid and alkali resistance is a crucial indicator. With the continuous development of industry and daily life, textiles come into contact with various acidic and alkaline environments. For example, in industrial production, workers' clothing may be exposed to acidic and alkaline chemicals; in daily life, some cleaning products also have certain acidity or alkalinity, which can affect fabrics upon contact. If the acid and alkali resistance of textiles is poor, contact with acidic or alkaline substances may cause problems such as discoloration, decreased strength, and fiber damage, affecting not only the fabric's appearance and lifespan but also potentially threatening the health and safety of users. Therefore, accurately testing the acid and alkali resistance of textiles is of great significance for ensuring fabric quality and meeting the needs of different application scenarios.

[0003] The current conventional method for testing the acid and alkali resistance of textile fabrics involves immersing the fabric in an acid or alkali solution bath for a specified time, then removing it and using specialized testing equipment to test its tensile strength after the acid and alkali immersion, thereby obtaining data on the fabric's acid and alkali resistance. However, this testing method has significant shortcomings, resulting in unreliable data. This is because the prolonged immersion in the acid or alkali solution bath fails to effectively simulate the actual performance changes of the fabric after contact with acid or alkali liquids in the air, making it difficult to obtain more reliable data that can provide strong support for practical applications. Summary of the Invention

[0004] This invention relates to an acid and alkali resistance testing device for textile fabric production, which solves the problem of conventional testing methods for the acid and alkali resistance of textile fabrics. The conventional method usually involves immersing the fabric in an acid or alkali solution for a long time to test its acid and alkali resistance. This method cannot effectively simulate the actual performance changes of the fabric after contact with acid or alkali liquids in the air environment, thus making it difficult to obtain more reliable data that can provide strong support for practical applications.

[0005] In a first aspect, this invention provides an acid and alkali resistance testing device for textile fabric production, specifically comprising: a testing soaking tank, a top tank cover, a rotating main shaft, a fabric clamping frame, a movable slide, a fabric clamping movable frame, screws, tension springs, nuts, a drive motor, and a synchronous belt; the top tank cover is rotatably connected to the top of the testing soaking tank, and the top tank cover and the testing soaking tank form a closed tank-shaped structure; the rotating main shaft is connected inside the testing soaking tank, and two fabric clamping frames are fixedly connected to the outside of the rotating main shaft; the movable slide is connected to the outside of the rotating main shaft, and two fabric clamping movable frames are connected to the outside of the movable slide; screws are connected inside the fabric clamping frame and the fabric clamping movable frame, and tension springs are connected to the outside of the fabric clamping movable frame; nuts are connected to the outside of the rotating main shaft; a drive motor is fixedly connected to the outside of the testing soaking tank, and a synchronous belt is connected to the outside of the drive motor, and the synchronous belt is connected to the rotating main shaft.

[0006] Furthermore, the fixed clamping frame is provided with screw holes A at equal intervals on its outer side, and the movable clamping frame is provided with screw holes B at equal intervals on its outer side. Screws are threaded into screw holes A and screw holes B. When the opposite ends of the textile fabric are respectively connected to the fixed clamping frame and the movable clamping frame, the screws are tightened so that the screw tips are inserted into the textile fabric, thereby achieving the effect of clamping and fixing the textile fabric.

[0007] Furthermore, the rotating spindle is rotatably connected to the detection soaking tank, a large pulley is provided at the end of the rotating spindle, and a small pulley is provided on the drive shaft of the drive motor. The small pulley is connected to the large pulley through a synchronous belt.

[0008] Furthermore, when the rotating spindle drives the fixed and movable clamping frames to the bottom, they are located in the acid and alkali solution inside the immersion tank. When the rotating spindle drives the fixed and movable clamping frames to the top, they are located above the acid and alkali solution. The drive motor drives the rotating spindle to rotate at a constant speed via a synchronous belt, and the fixed and movable clamping frames move at a constant speed, immersing the textile fabric in the acid and alkali solution inside the immersion tank and then lifting it above the solution. The textile fabric comes into contact with the air, and this continuous cycle causes the residual acid and alkali on the surface of the textile fabric to undergo a secondary reaction with oxygen and carbon dioxide in the air, accelerating material degradation and exposing weaknesses that cannot be detected by immersion testing alone.

[0009] Furthermore, the movable carriage has a through hole inside, through which the rotating spindle slides. The movable carriage has symmetrical sliding holes on the outside, and the rotating spindle has symmetrical guide blocks on the outside. The guide blocks are slidably connected to the sliding holes. The sliding cooperation between the guide blocks and the sliding holes provides a guiding effect for the movement of the movable carriage.

[0010] Furthermore, the movable slide is symmetrically provided with guide holes at its end, and guide rods are symmetrically provided on the outside of the cloth clamping frame, with the guide rods sliding through the guide holes.

[0011] Furthermore, the movable slide is provided with a fixed pull hole at its end, and the fabric clamping movable frame is provided with a movable pull hole on its outside. One end of the tension spring is connected to the fixed pull hole, and the other end of the tension spring is connected to the movable pull hole. The guide rod slides in cooperation with the guide hole, which plays a guiding role in moving the fabric clamping movable frame. The tension spring applies tension to achieve the resetting effect of the fabric clamping movable frame.

[0012] Furthermore, the rotating spindle is provided with an external thread, and the nut is threadedly connected to the outside of the rotating spindle, with one end of the movable slide in contact with the nut.

[0013] Furthermore, a spring is fitted outside the rotating spindle, and the other end of the movable slide contacts the spring. A retaining ring is provided outside the rotating spindle, and the retaining ring contacts the end of the spring. The spring provides an elastic reset effect for the movable slide. After the two ends of the textile fabric are clamped and fixed, the nut is rotated, and the nut drives the movable slide to move. The spring contracts under force, and the tension spring stretches under force. The distance between the fixed clamping frame and the moving clamping frame increases. The tension spring applies tension to the textile fabric, keeping the textile fabric taut and allowing the textile fabric to come into more full contact with the acid and alkali solutions.

[0014] This invention provides an acid and alkali resistance testing device for textile fabric production, which has the following beneficial effects:

[0015] In use, when the two ends of the textile fabric are connected to the fixed clamping frame and the movable clamping frame respectively, the screws are tightened so that the screw tips are inserted into the textile fabric, which clamps and fixes the textile fabric, ensuring the firmness of the connection between the textile fabric and the fixed clamping frame and the movable clamping frame. The drive motor drives the rotating main shaft to rotate at a constant speed through the synchronous belt. The rotating main shaft moves the fixed clamping frame and the movable clamping frame at a constant speed, so that the textile fabric is immersed in the acid and alkali solution inside the test soaking tank, and then raised above the acid and alkali solution. The textile fabric comes into contact with the air, and the cycle continues continuously. This causes the acid and alkali remaining on the surface of the textile fabric to react with the oxygen and carbon dioxide in the air, which accelerates the degradation of the material and exposes weaknesses that cannot be detected by soaking test alone, thus ensuring the accuracy of the acid and alkali resistance test data of the textile fabric.

[0016] In addition, the guide block slides into the sliding hole to guide the movement of the movable carriage and prevent the movable carriage from twisting; the guide rod slides into the guide hole to guide the movement of the fabric clamping frame, and the tension spring applies tension to achieve the reset effect of the fabric clamping frame.

[0017] Furthermore, the spring provides elastic reset for the movable slide. After the two ends of the fabric are clamped and fixed, rotating the nut causes the movable slide to move, the spring contracts under pressure, and the tension spring stretches under pressure, increasing the distance between the fixed and movable clamping frames. The tension spring applies tension to the fabric, keeping it taut and allowing for more thorough contact with acid and alkali solutions, thus improving the measurement of the fabric's tensile strength under acid and alkali conditions. After the acid and alkali resistance test is completed, rotating the nut in the opposite direction causes the main shaft to move and reset under the influence of the spring. The tension spring contracts, allowing the screw to be loosened in the opposite direction, separating the fabric from the fixed and movable clamping frames. The operation is simple.

[0032] 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 some embodiments of the present invention, but not all embodiments. Based on the described 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.

[0033] Please refer to Figures 1 to 8 Example 1:

[0034] This invention proposes an acid and alkali resistance testing device for textile fabric production, comprising: a testing soaking tank 1, a top tank cover 2, a rotating main shaft 3, a fabric clamping frame 4, a movable slide 5, a fabric clamping moving frame 6, screws 7, tension springs 8, nuts 9, a drive motor 11, and a synchronous belt 12; the top tank cover 2 is rotatably connected to the top of the testing soaking tank 1, and the top tank cover 2 and the testing soaking tank 1 form a closed tank-shaped structure; the rotating main shaft 3 is connected inside the testing soaking tank 1, and two fabric clamping frames 4 are fixedly connected to the outside of the rotating main shaft 3; the movable slide 5 is connected to the outside of the movable slide 5, and two fabric clamping moving frames 6 are connected to the outside of the movable slide 5; screws 7 are connected inside the fabric clamping frame 4 and the fabric clamping moving frame 6. 6. An external tension spring 8 is connected to the external part of the rotating main shaft 3; a nut 9 is connected to the external part of the detection soaking tank 1; a drive motor 11 is fixedly connected to the external part of the drive motor 11, and a synchronous belt 12 is connected to the external part of the drive motor 11, which is connected to the rotating main shaft 3; the fabric clamping frame 4 has screw holes A41 equidistantly arranged on its external part, and the fabric clamping moving frame 6 has screw holes B601 equidistantly arranged on its external part; screws 7 are threaded into screw holes A41 and B601; when the opposite ends of the textile fabric are respectively connected to the fabric clamping frame 4 and the fabric clamping moving frame 6, the screws 7 are tightened so that the tips of the screws 7 are inserted into the textile fabric, which achieves the effect of clamping and fixing the textile fabric, ensuring the firmness of the connection between the textile fabric and the fabric clamping frame 4 and the fabric clamping moving frame 6.

[0035] In this embodiment, the rotating spindle 3 is rotatably connected to the detection soaking tank 1. A large pulley 301 is provided at the end of the rotating spindle 3, and a small pulley 1101 is provided on the drive shaft of the drive motor 11. The small pulley 1101 is connected to the large pulley 301 through the synchronous belt 12. When the rotating spindle 3 drives the fixed clamping frame 4 and the movable clamping frame 6 to rotate to the bottom, the fixed clamping frame 4 and the movable clamping frame 6 are located in the acid and alkali solution inside the detection soaking tank 1. When the rotating spindle 3 drives the fixed clamping frame 4 and the movable clamping frame 6 to rotate to the top, the fixed clamping frame 4 and the movable clamping frame 6 are located above the acid and alkali solution.

[0036] Using the above technical solution, the drive motor 11 drives the rotating main shaft 3 to rotate at a constant speed through the synchronous belt 12. The rotating main shaft 3 clamps the fabric fixed frame 4 and the fabric moving frame 6 at a constant speed, so that the textile fabric is immersed in the acid and alkali solution inside the test soaking tank 1, and then lifted above the acid and alkali solution. The textile fabric comes into contact with the air and continues to cycle repeatedly, so that the acid and alkali remaining on the surface of the textile fabric reacts with the oxygen and carbon dioxide in the air, which accelerates the degradation of the material and exposes the weaknesses that cannot be found in the soaking test alone, thus ensuring the accuracy of the acid and alkali resistance test data of the textile fabric.

[0037] In Example 2, based on Example 1, the movable slide 5 is provided with a through hole 501 inside, the rotating spindle 3 slides through the through hole 501, the movable slide 5 is provided with symmetrical sliding holes 502 outside, the rotating spindle 3 is provided with symmetrical guide blocks 302 outside, and the guide blocks 302 are slidably connected to the sliding holes 502.

[0038] By adopting the above technical solution, the guide block 302 and the sliding hole 502 are slidably engaged to guide the movement of the movable carriage 5 and prevent the movable carriage 5 from twisting.

[0039] In this embodiment, the movable slide 5 is symmetrically provided with guide holes 503 at its end, and the fabric clamping frame 6 is symmetrically provided with guide rods 602 on its outside. The guide rods 602 slide through the guide holes 503. The movable slide 5 is provided with a fixed pull hole 504 at its end, and the fabric clamping frame 6 is provided with a movable pull hole 603 on its outside. One end of the tension spring 8 is connected to the fixed pull hole 504, and the other end of the tension spring 8 is connected to the movable pull hole 603.

[0040] Using the above technical solution, the guide rod 602 slides with the guide hole 503 to guide the movement of the fabric clamping frame 6, and the tension is applied by the tension spring 8 to achieve the reset effect of the fabric clamping frame 6.

[0041] In this embodiment, the rotating spindle 3 is provided with an external thread, the nut 9 is threadedly connected to the outside of the rotating spindle 3, one end of the movable slide 5 is in contact with the nut 9, a spring 10 is fitted on the outside of the rotating spindle 3, the other end of the movable slide 5 is in contact with the spring 10, and a retaining ring 303 is provided on the outside of the rotating spindle 3, which is in contact with the end of the spring 10.

[0042] Using the above technical solution, the spring 10 provides an elastic reset effect for the movable slide 5. After the two ends of the textile fabric are clamped and fixed, the nut 9 is rotated, which moves the movable slide 5. The spring 10 contracts under force, and the tension spring 8 is stretched under force. The distance between the fixed clamping frame 4 and the movable clamping frame 6 increases. The tension spring 8 applies tension to the textile fabric, keeping it taut. This allows the textile fabric to come into more full contact with the acid and alkali solutions, and better measures the tensile strength of the textile fabric under acid and alkali conditions. After the acid and alkali resistance test of the textile fabric is completed, the nut 9 is rotated in the opposite direction. The rotating main shaft 3 moves and resets under the influence of the spring 10. The tension spring 8 contracts, and the screw 7 can be loosened in the opposite direction to separate the textile fabric from the fixed clamping frame 4 and the movable clamping frame 6. The operation is simple.

[0043] The working principle of this embodiment is as follows: First, the two ends of the textile fabric are connected to the fixed clamping frame 4 and the movable clamping frame 6 respectively. The screws 7 are tightened so that their tips are inserted into the textile fabric, thus clamping and fixing it. Then, the nut 9 is rotated, causing the movable slide 5 to move. The spring 10 contracts under pressure, and the tension spring 8 stretches under pressure, increasing the distance between the fixed clamping frame 4 and the movable clamping frame 6. The tension spring 8 applies tension to the textile fabric, keeping it taut. The drive motor 11 drives the rotating spindle 3 to rotate at a constant speed via the synchronous belt 12. The rotating spindle 3, the fixed clamping frame 4, and the movable clamping frame 6 move at a constant speed, causing the textile fabric to be submerged. The fabric is immersed in an acid or alkali solution inside the soaking tank 1, and then lifted above the solution. This exposes the fabric to air, and the process is repeated continuously. This causes a secondary reaction between the residual acid or alkali on the fabric surface and oxygen and carbon dioxide in the air, accelerating material degradation and revealing weaknesses that cannot be detected by soaking alone. This allows for a better measurement of the fabric's tensile strength under acid and alkali conditions. After the acid and alkali resistance test is completed, the nut 9 is rotated in the reverse direction. The rotating spindle 3 moves back to its original position under the influence of the spring 10, and the tension spring 8 is in a contracted state. This allows the screw 7 to be loosened in the reverse direction, separating the fabric from the fixed clamp 4 and the moving clamp 6. The operation is simple.
