Description

Technical Field

[0001] The utility model relates to the technical field of viscosity detection, in particular to a device for detecting viscosity of recycled polyester chips. Background Art

[0002] Recycled polyester chips (usually refers to polyester chips recovered from waste polyester materials through recycling, crushing, cleaning, melting, recrystallization and other processes) are widely used in textiles, packaging, automotive parts and other fields. In these applications, the performance of recycled polyester chips, especially its viscosity, has a crucial impact on the final quality of the product. When testing the viscosity of recycled polyester chips, a magnetic rotation viscometer is required. The internal rotor is driven by magnetic force to rotate in the sample liquid. The rotor is coupled with the external drive device (such as a motor) through magnetic force, thereby avoiding direct mechanical contact and reducing friction and wear. When the rotor rotates in the liquid, it will be subject to the resistance of the liquid, which is proportional to the viscosity of the liquid. The viscosity of the liquid can be indirectly measured by measuring the force or torque required for the rotor to rotate.

[0003] During the viscosity test, the viscometer needs to drip polyester chip liquid into the test tube being tested. The main purpose is to simulate and control the flow behavior of the liquid under specific conditions, so as to accurately measure its viscosity. However, the height and position of the dripping liquid in the existing viscosity test process are often fixed. In actual applications, the liquid may flow into the container or pipe from various heights and angles. The dripping liquid at a fixed height and position cannot simulate these different flow conditions, making the experimental conditions closer to reality. Utility Model Content

[0027] The working principle of this embodiment is as follows: when testing the viscosity of the recycled polyester chips, firstly, the sliced ​​recycled polyester is placed in the dripping tank 501 and the detection cylinder 2, then the heating plate is started to liquefy the recycled polyester chips in the dripping tank 501 and the detection cylinder 2, and then the rotor in the detection cylinder is started to rotate by magnetic force, and then the viscosity of the recycled polyester is tested.
