Description

Technical Field

[0001] The invention relates to the technical field of VOC detection of textiles, in particular to a VOC detection placement rack for textiles. Background Art

[0002] During the production of textiles, some volatile organic gases are generated, which are also called VOCs. VOCs in textile waste gas mainly come from two aspects. One is the pre-treatment and functional post-treatment of textiles (such as the use of setting machines, baking machines, singeing machines, sanding machines, etc. to treat fabrics). During heat setting, various dye auxiliaries and coating auxiliaries on textiles will be released in the form of gas, mainly some organic gases such as formaldehyde, polybenzenes, aromatic hydrocarbons, etc. The second is the coating thinners produced in the printing section, mainly benzene, toluene, xylene, referred to as triphenyl, in addition to formaldehyde, etc.

[0003] At present, in order to protect the environment and reduce pollution, people usually use VOC detection boxes to test textiles during textile production. The staff places the textiles in a constant temperature and humidity VOC detection box. At a certain temperature, the VOC inside the textiles evaporates quickly and mixes with the air in the VOC detection box. Then the detection probe inside the VOC detection box measures the concentration of VOC evaporated from the textiles, which is convenient for detecting whether the textiles meet the factory standards.

[0004] However, when the existing VOC detection box is used to detect textiles, since the textiles are relatively soft, it is easy for the textiles to have some wrinkles, resulting in a reduction in the contact area between the textiles and the air, which in turn affects the volatilization of VOCs in the textiles. At the same time, these wrinkles are easily folded together to form small spaces, and the VOCs volatilized from the fabric inside the folds of the textiles cannot evaporate quickly into the air. As a result, when the VOC detection box detects the concentration of VOCs volatilized from the textiles, the detected value is lower than the actual concentration of VOCs volatilized from the textiles, which affects the authenticity of the VOC detection. Therefore, it does not meet the existing needs. In this regard, we propose a textile VOC detection placement rack. Summary of the invention

[0038] Working principle: When in use, the staff places one end of the textile between the two pressing plates 32, and then the pressing plates 32 are moved closer to each other under the action of the pressing spring 31, so that the anti-dropping card pin 33 is inserted into the textile. Then the staff pushes the device into the VOC detection box, and then the staff electrically connects the conductive ring 29, the blowing fan 4, the heating plate 5 and the spinning motor 6 with the power supply in the VOC detection box, so that the power supply wires in the positive and negative electrode slide grooves inside the conductive ring 29 are energized. Then, the current passes through the positive and negative contact wires inside the power input rod 30 to energize the mobile motor 21, and the mobile motor 21 drives the mobile rubber wheel 27 to rotate. Since the outer part of the mobile rubber wheel 27 is in friction contact with the friction belt 17, and at the same time, one end of the power input rod 30 is stuck in the inner part of the belt outer plate 13, the mobile rubber wheel 27 drives the motor mounting bracket 22 to move in the gap between the belt outer plate 13 and the belt inner plate 14, so that the belt shaft 18 drives the textile to move outside the textile winding hollow rod 10, and at the same time, the spin motor 6 drives the driving pulley 25 to rotate, so that the transmission toothed belt 12 drives the connecting pulley 24 The spinning rod 11 drives part of the textile to rotate around the hollow rod 10, providing a part of the moving force for the textile. Next, the blowing fan 4 sucks the air in the VOC detection box into the hot air box 3, and then the air forms hot air under the action of the heating plate 5. The hot air then enters the middle part connected to the hot air pipe 23, and then is discharged through the hole outside the middle part connected to the hot air pipe 23, so that the hot air is evenly blown on the outside of the textile, so that the textile is quickly heated to the specified temperature, which is convenient for the textile to quickly volatilize VOC gas. As the belt shaft 18 drives the textile to move continuously outside the hollow rod 10 wrapped around the textile, the textile is fully in contact with the air, and the textile The volatile VOC quickly mixes with the air, and the textiles can be evenly heated while moving continuously, so that the temperature of the textiles can be stably and evenly raised to a suitable temperature, avoiding uneven heating of the textiles in the fixed wind direction. Since the thermal conductivity of the textiles is relatively weak, the local temperature of the textiles is prevented from being too high, and the textiles are prevented from being scalded and some non-detection gases are generated, thereby ensuring the accuracy of the VOC detection box. Finally, the detection probe in the VOC detection box can detect the VOC concentration in the air in the VOC detection box. The conductive ring 29 is installed in the device so that it can cooperate with the power input rod 30 to facilitate the power supply to the mobile motor 21, ensuring The mobile motor 21 can run stably to ensure the complete functionality of the device. The mobile rubber wheel 27 can be installed to rub against the friction belt 17, driving the motor mounting bracket 22 to move in the gap between the inner plate 14 and the outer plate 13 of the belt material, so that the belt shaft 18 can drive the textile to move outside the textile winding hollow rod 10 according to the specified trajectory. There is no need for the staff to tediously wind the textile around the outside of the textile winding hollow rod 10, which reduces the workload of the staff, makes the device more convenient to use, facilitates the rapid VOC detection of textiles, and makes the device more user-friendly. At the same time, the belt shaft 18 drives the textile to move continuously.Prevent the formation of wrinkles on textiles, ensure that the volatile VOC in the textiles can quickly and fully contact the air, avoid the situation where the VOC detection box detects the concentration of VOC volatilized by the textiles, and the detected value is less than the actual concentration of VOC volatilized by the textiles, so as to ensure the authenticity of the VOC detection. Install the adjustable telescopic bracket 8 to cooperate with the fixed bracket 7 and the textile winding hollow rod 10 to stretch the textile, so that the device can detect textiles of different lengths, and at the same time avoid wrinkles on the textiles, and ensure that the textiles can fully contact the air. Install the self-spinning rod 11, the connecting pulley 24 and the transmission toothed belt 12 to drive part of the textile to rotate around the hollow rod 10 under the action of the driving pulley 25, reduce the pressure of the belt shaft 18 to drive the textile to move, and make the textile move more smoothly. Install the pressing spring 31 so that the pressing plate 32 can cooperate with the anti-slipping pin 33 to clamp one end of the textile, prevent the anti-slipping pin 33 from slipping when moving, make the device fix the textile more convenient, and enhance the convenience of the device when using.
