[0002] The negative ion measuring device for negative ion fiber fabrics is an instrument specifically designed to detect the concentration of negative ions released by such fabrics. Its core function is to accurately quantify the amount of negative ions released, providing data support for product quality assessment and research and development.

[0003] In existing technologies, traditional negative ion measuring devices, when used to detect negative ion fiber fabrics, often require different friction clamping forces due to the varying thicknesses and materials of the fabrics. The fixed position of the traditional friction pressing structure makes it difficult for these devices to accurately adapt to various samples during practical use. Furthermore, improper clamping can easily lead to fabric damage or detection failure. Therefore, this invention proposes a negative ion measuring device for negative ion fiber fabrics to address the problems existing in the prior art. Utility Model Content

A stepper motor is installed at the center of the rear end of the back plate. Four sets of sliding grooves are equidistantly distributed in a ring at both ends of the partition. Four sets of centrally symmetrical extension frames are fixedly connected to the rear end of the partition and are correspondingly distributed along the edge of the sliding groove. Guide rails are fixedly connected to the left and right edges of the extension frames. A lead screw is rotatably installed on the inner wall of the extension frame. A servo motor is installed at the end of the extension frame near the outer wall of the partition.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-7 This utility model provides an embodiment: a negative ion measuring device for negative ion fiber fabric, including a detection box 2, and a roller frame adjustment structure with multiple limiting assistance set inside the detection box 2. A back plate 3 and a partition 4 are installed sequentially from back to front on the inner wall of the rear end of the detection box 2. A stepper motor 15 is installed at the center of the rear end of the back plate 3. Four sets of sliding grooves 10 are equidistantly distributed in a ring at both ends of the partition 4. Four sets of centrally symmetrically distributed extension frames 11 are fixedly connected to the rear end of the partition 4, corresponding to the edge of the sliding grooves 10. Guide rails 12 are fixedly connected to the left and right edges of the extension frames 11. A lead screw 14 is rotatably installed on the inner wall of the extension frame 11. A servo motor 13 is installed at one end of the extension frame 11 near the outer wall of the partition 4. The output end of the servo motor 13 passes through the extension frame 11 and is connected to the lead screw 14. Negative ion detectors 6 are installed at the four corner edges of the inner wall of the detection box 2.

[0025] The distance between the four sets of friction rollers 24 and the main roller frame 22 is precisely adjusted by the servo motor 13. Combined with the rotation of the main roller driven by the stepper motor 15, stable friction and pressing of fabrics of different thicknesses is achieved, which ensures the effective release of negative ions and avoids excessive compression that could damage the fabric. The front and rear clamping cooperation of the first limiting block 17 and the second limiting block 19, and the linear constraint of the sliding sleeve 16 and the guide rail 12, form a double limiting and guiding mechanism to ensure that the auxiliary roller frame 20 does not deviate during adjustment and operation, thereby improving the stability of the displacement adjustment of the four sets of friction rollers 24.

[0026] Please see Figures 5-7In this embodiment, the roller frame adjustment structure includes a main roller frame 22 rotatably mounted at the center of the partition plate 4, four sets of auxiliary roller frames 20 movably disposed in four sets of slide grooves 10, and a first limiting block 17 and a second limiting block 19 fixed to the outer wall of the rear end of the auxiliary roller frame 20 and symmetrically distributed front and rear. The output end of the stepper motor 15 passes through the back plate 3 and the partition plate 4 and is connected to the rear end of the main roller frame 22. The outer wall of the rear end of the auxiliary roller frame 20 is in contact with the inner wall of the slide groove 10. The rear end of the second limiting block 19 is in contact with the front end of the partition plate 4, and the front end of the first limiting block 17 is in contact with the rear end of the partition plate 4. The combination design of the main roller frame 22 and four sets of auxiliary roller frames 20 achieves multi-directional stable support for the fabric. The stepper motor 15 drives the main roller frame 22, and in conjunction with the sliding groove 10 limiting structure of the auxiliary roller frames 20, the fabric tension and contact angle can be precisely adjusted to ensure a consistent fabric surface condition during testing. The dual limiting design of the first limiting block 17 and the second limiting block 19 effectively prevents the auxiliary roller frame 20 from shifting or falling off during movement, improving structural stability and adjustment accuracy. Two sets of sliding sleeves 16 are fixedly connected to the outer wall of the first limiting block 17, which are symmetrically distributed. The inner wall of the sliding sleeve 16 fits against the outer wall of the guide rail 12. A threaded groove 18 is opened through the outer wall of the first limiting block 17, which is adapted to the lead screw 14. The centrally symmetrical sliding sleeve 16 cooperates with the guide rail 12 to ensure the straightness of the auxiliary roller frame 20 during movement and reduce mechanical wear. The threaded engagement between the screw groove 18 and the lead screw 14 realizes the transmission self-locking function, which can precisely control the displacement of the auxiliary roller frame 20 and prevent loosening after adjustment. This structure makes the roller frame spacing adjustment more stable and improves the reliability of equipment operation. The outer wall of the main roller frame 22 has three sets of mounting grooves 23 that are equidistantly distributed around it. Velcro 21 is fixed in the mounting grooves 23, and the rear end of the main roller frame 22 is attached to the front end of the partition plate 4. The surrounding mounting grooves 23 can be adapted to different specifications of detection accessories. The fastening method of the Velcro 21 realizes the quick disassembly and assembly of accessories, which is convenient for replacing detection components or cleaning and maintenance. The contact design between the main roller frame 22 and the partition plate 4 reduces the shaking space and ensures the stability of the fabric contact position during detection. A friction roller 24 is mounted on the auxiliary roller frame 20, and the rear end of the friction roller 24 is attached to the front end of the second limit block 19. The friction roller 24 can increase the friction with the fabric surface to prevent the fabric from slipping or shifting during testing; the friction material can buffer the direct contact between the fabric and the metal roller frame to avoid damage to the fabric surface; the fit structure between the friction roller 24 and the limiting block simplifies the assembly process and makes it easier to replace worn parts separately later.

[0027] Please see Figures 3-4In this embodiment, a door panel 1 is hinged to the front edge of the detection box 2. Fan slots 8 are provided through the front and rear ends of the door panel 1, and ventilation fans 9 are installed in the fan slots 8. The hinged door panel 1 facilitates sample loading and unloading, and at the same time forms a closed detection environment, reducing external airflow interference. The ventilation fan 9 in the fan slots 8 can realize air circulation inside the detection box 2, avoiding measurement deviations caused by the accumulation of negative ion concentration. The through-flow fan design can adjust the air pressure balance inside the box, ensuring the airflow stability of the sampling system.

[0028] Please see Figure 3 In this embodiment, a storage slot 7 is provided at the right end of the detection box 2. A processing computer 5 is hinged to the inner edge of the storage slot 7, and the outer wall of the processing computer 5 fits against the inner wall of the storage slot 7. The storage slot 7 can embed the processing computer 5, saving the overall space occupied by the equipment; the integrated design of the computer and the detection box 2 reduces external wiring and lowers signal transmission interference; the hinged structure allows the computer to be flexibly adjusted at the angle, making it convenient for operators to view data or set parameters, thus improving the human-computer interaction experience.

[0029] In use, first open the hinged door panel 1, and fix the negative ion fiber fabric sample through the Velcro 21 on the main roller frame 22, so that the fabric surrounds the main roller frame 22 and is tensioned between the friction rollers 24 of the four sets of auxiliary roller frames 20; then, start the servo motor 13 according to the fabric thickness, and the servo motor 13 drives the lead screw 14 to rotate, causing the first limiting block 17 to slide along the guide rail 12. At the same time, the sliding sleeve 16 ensures the straightness of the displacement of the first limiting block 17, so as to adjust the distance between the auxiliary roller frame 20 and the main roller frame 22. The double limiting of the first limiting block 17 and the second limiting block 19 can ensure that the auxiliary roller frame 20 is in the groove. The device moves stably within 10 seconds to avoid deviation. Then, the door panel 1 is closed to form a closed environment. The stepper motor 15 is then started to drive the main roller frame 22 to rotate. At the same time, the four sets of friction rollers 24 release negative ions from the fabric through friction and pressing. The negative ion detectors 6, which are distributed in a matrix at the four corners, collect data synchronously and transmit it to the processing computer 5 in the storage tank 7. Finally, the processing computer 5 analyzes and displays the detection data, generates a visual report, and completes the quantitative assessment of the amount of negative ions released by the fabric. After the analysis is completed, the ventilation fan 9 is started to circulate the air in the detection box 2 to the outside to avoid the accumulation of negative ion concentration and interference with the next detection.

[0030] Through the above steps, the distance between the four sets of friction rollers 24 and the main roller frame 22 is precisely adjusted by the servo motor 13. Combined with the rotation of the main roller driven by the stepper motor 15, stable friction and pressing of fabrics of different thicknesses is achieved, which ensures the effective release of negative ions and avoids excessive compression that could damage the fabric. The front and rear clamping cooperation of the first limiting block 17 and the second limiting block 19, and the linear constraint of the sliding sleeve 16 and the guide rail 12, form a double limiting and guiding mechanism to ensure that the auxiliary roller frame 20 does not deviate during adjustment and operation. This improves the stability of the displacement adjustment of the four sets of friction rollers 24 and solves the problem that the existing friction pressing type fabric negative ion measuring device has poor single-distance adaptability and poor stability during friction structure adjustment.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
