Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of dental floss performance detection, and more particularly to a detection device suitable for dental floss performance detection. Background Art
[0002] With the improvement of oral care awareness, dental floss, as an important oral cleaning tool, its physical properties directly affect the use effect and safety. Traditional detection methods mainly rely on manual operation and single-device testing, with problems such as low efficiency, poor accuracy, and data dispersion. Early detection devices mostly used universal material testing machines for tensile strength testing, but could not simulate the multi-directional composite stress borne by dental floss during actual use. For wear resistance detection, simple friction testers are generally used, and the surface wear is evaluated through reciprocating motion at a fixed frequency, but there is a lack of control over the real simulation environment of the dental floss-dental interdental contact interface. For flexibility testing, the bending radius method is mostly used, relying on visual judgment by operators, with subjective errors. Although automated detection devices have emerged in recent years, most are still limited to single-parameter testing and have not achieved tensile strength, wear resistance, elongation at break, surface smoothness, etc.
[0003] During the use of existing dental floss performance monitoring devices, there are some deficiencies, which are as follows:
[0004] During the process of monitoring dental floss by existing dental floss performance monitoring devices, it is mainly for the anti-twisting property and flexibility of dental floss. The monitoring of these properties requires positioning the dental floss before monitoring. When the existing dental floss positioning device is positioning, since the dental floss is multi-stranded, some strands in the dental floss will break away from the positioning during the use of the existing device, so it is not convenient to ensure the effective detection of dental floss performance.

[0013] The technical effects and advantages of the present invention:
[0014] 1. When the present invention conducts a torsion test on dental floss, multiple strands of dental floss are placed inside two first clamping blocks.

Then place the other end of the positioned dental floss between the second clamping block 2033 and the third clamping block 2036 and tighten it. Then, drive the hydraulic rod 2035 to contract by the operation of the hydraulic cylinder 2034, so that the third clamping block 2036 moves closer to the second clamping block 2033 to clamp a single strand of dental floss. Then, position each strand of dental floss on the dental floss positioning assembly 203 in sequence.

Under the clamping and positioning of the transmission gear 2018 on the pushing tooth 2025, the pushing circular plate 2021 remains stationary relative to the rotary disc 2012. Then, the dental floss positioning assembly 203 rotates following the rotary disc 2012, and then the dental floss continues to wind. And during the continuous winding of the dental floss, the second servo motor 2017 can be operated to drive the transmission gear 2018 to rotate. Then, drive the pushing circular plate 2021 to rotate relative to the rotary disc 2012 through the meshing of the pushing tooth 2025 and the transmission gear 2018.

There is a clearance fit between the width of the guiding groove 2014 and the diameter of the push rod 2031.

[0031] Working principle of the present invention: When performing a torsion test on dental floss, multiple strands of dental floss are placed inside two first clamping blocks 107. Then, the two first clamping blocks 107 are pushed closer by a sliding rod 106 to position the dental floss to be torsion-tested. Then, the other end of the positioned dental floss is placed between a second clamping block 2033 and a third clamping block 2036 and tightened. Subsequently, a hydraulic cylinder 2034 works to drive a hydraulic rod 2035 to contract, causing the third clamping block 2036 to move closer to the second clamping block 2033 to clamp a single strand of dental floss. Then, each strand of dental floss is sequentially positioned on a dental floss positioning assembly 203. Then, a first servo motor 2011 works to drive a rotating disc 2012 to rotate, which in turn drives a guiding and positioning plate 2013 to rotate. Under the clamping and positioning of a transmission gear 2018 on a pushing tooth 2025, a pushing circular plate 2021 remains stationary relative to the rotating disc 2012. Subsequently, the dental floss positioning assembly 203 rotates following the rotating disc 2012, causing the dental floss to continuously wind. And during the continuous winding of the dental floss, the second servo motor 2017 can work to drive the transmission gear 2018 to rotate. Then, through the mutual meshing of the pushing tooth 2025 and the transmission gear 2018, the pushing circular plate 2021 is driven to rotate relative to the rotating disc 2012. Then, the dental floss positioning assembly 203 is pushed through an arc-shaped pushing groove 2024, and under the positioning of a guiding groove 2014 and a guiding rod 2015 on the dental floss positioning assembly 203, the dental floss positioning assembly 203 synchronously moves closer to the inside and spreads out. When the dental floss is wound, the dental floss positioning assembly 203 spreads or gathers to evenly wind between single strands of the dental floss, enabling the dental floss to be evenly stressed during the winding process, which is convenient for effectively detecting the winding and torsion performance of the dental floss;
[0032] When performing a flexibility test, the second servo motor 2017 works to cause the dental floss positioning assembly 203 to move closer, gathering multiple strands of dental floss together. Then, the flexibility of the dental floss can be detected through an impact component, which is convenient for the user to detect the flexibility of the dental floss, enabling the device to simultaneously detect the torsion and flexibility of the dental floss.
