Description

Technical Field

[0001] This utility model relates to the field of viscometer technology, specifically a rotary viscometer. Background Technology

[0002] A viscometer is an instrument used to measure the viscosity of fluids. In the production of adhesives, viscometers are needed to measure the viscosity of the adhesive. Existing rotary viscometers mainly consist of a base placed on a table, a column on the base, and electrical components such as a motor that drives the rotor and a torque detection structure slidingly mounted on the column. In use, the rotor is inserted into the adhesive to be tested, and after the motor driving the rotor is turned on, the viscosity of the adhesive can be measured by the rotation of the rotor. The test result is displayed on a reading dial. After testing the sample, when the rotor is withdrawn from the adhesive, adhesive residue easily remains on the rotor, and adhesive easily drips after the barrel is removed, causing contamination of the viscometer. Furthermore, once the adhesive solidifies, it is difficult to clean, seriously affecting the normal use of the viscometer. Therefore, this application proposes a rotary viscometer to solve the above problems. Utility Model Content
