Description

Technical Field

[0001] The utility model relates to the technical field of textile detection, in particular to a textile pH detection device. Background Art

[0002] The pH value is an index used to represent the acidity and alkalinity of a solution, usually ranging from 0 to 14. Among them, a pH value less than 7 indicates that the solution is acidic, a pH value greater than 7 indicates that the solution is alkaline, and a pH value equal to 7 indicates that the solution is neutral. The human skin surface is in a weakly acidic environment with a pH value of 4.5 - 5.5; textile pH detection devices are usually used to test the acidity and alkalinity of textiles to ensure their quality and applicability. Conducting pH detection on textiles is to evaluate the acid-base properties of textiles, which can determine their compatibility with the skin and the possible impact on human health.

[0003] In the prior art, CN202322020881.0, a textile pH value detection device, includes: a detection box. The left and right sides of the inner wall of the detection box near the bottom are jointly connected by a bearing to a connecting shaft. By placing the textile into the connecting box and then rotating the cylinder to drive the ring to move left and right reciprocally, the ring drives the connecting box to move left and right reciprocally, so that the textile placed in the connecting box moves in the solution, ensuring the full mixing of the textile and the solution. The textile will not be wound around the internal structure of the detection box during movement. However, the existing textile pH detection device has the following defects: 1. During the detection process of the textile pH value, in order to ensure the accuracy and reliability of the results, the GB / T7573 standard clearly stipulates that multiple repeated experiments need to be carried out and the average value is taken as the final result. However, the existing technology requires multiple repeated experiments and cannot be completed at one time, increasing the time cost; 2. The existing technology lacks cleaning of the device after detection. During the textile pH value detection process, residues or pollutants may be generated during the contact and mixing of the textile and the solution. If these residues or pollutants are not cleaned in time, they will affect the results of the next detection and will also cause a large amount of dirt to accumulate inside the device, affecting the normal operation and lifespan of the device.

[0004] Therefore, it is necessary to improve the existing textile pH detection device to solve the above problems. Summary of the Invention

[0005] The utility model overcomes the deficiencies of the prior art and provides a textile pH detection device, aiming to solve the problems of conducting multiple groups of textile pH detection experiments at one time and self-cleaning of the device in the prior art.

[0018] The present utility model solves the defects existing in the background technology, and the present utility model has the following beneficial effects:

[0019] (1) The utility model utilizes the integrated management of a multi-drum structure and a PLC control panel to achieve rapid and multiple repeated experiments for the pH value detection of textiles. By simultaneously setting multiple drums and detection boxes, each drum and detection box can independently perform the water bath extraction and pH value measurement of textile samples, while the PLC control panel can simultaneously control and manage the experimental processes of all drums and detection boxes. This design enables multiple repeated experiments to be carried out in one operation and automatically calculates the average value as the final result, greatly reducing the time cost and improving the detection efficiency. Compared with the prior art, the cumbersome operations of multiple repeated experiments are avoided, further improving the efficiency and accuracy of the experiment.

[0020] (2) The utility model introduces an automatic cleaning function to ensure the cleanliness and hygiene of the device after detection. After the pH value detection of textiles is completed, the PLC control panel can automatically start the cleaning program. By adding clean water to the drum and driving it to rotate, the automatic cleaning of the drum and the detection box is achieved. At the same time, the PLC control panel can also real-time monitor the pH value of the cleaning liquid until the pH value returns to the initial value of water, ensuring thorough cleaning. This design effectively removes the residues or pollutants generated during the contact and mixing of textiles and solutions, avoiding their influence on the next detection result and ensuring the cleanliness and hygiene of the equipment.

[0021] (3) The utility model utilizes the transmission mechanism of planetary gears and a rotating motor to achieve the full mixing and contact of samples and water in the drum. By driving the sun gear with the rotating motor, the planetary gear is driven to rotate along its own axis, enabling the textile samples in the drum to be fully mixed with water during rotation. At the same time, the same rotation speed is provided for the experiment, effectively improving the dissolution efficiency of pH-related substances and the accuracy of the experiment, providing a reliable basis for subsequent pH value measurement.
