[0022] In addition, the setting of the two movable positioning rods plays a positioning role for the circular mounting rod, making the circular mounting rod more stable after rotation; when the circular mounting rod rotates under the action of the driving gear A and the driving gear B, the circular mounting rod pushes the two movable positioning rods to move outward, so that the two movable positioning rods are separated from the two arc-shaped positioning grooves, and when the circular mounting rod rotates to half a circle, the two movable positioning rods continue to be inserted in the two arc-shaped positioning grooves.

[0023] 2.

[0024] In addition, when the viscosity test of the polyurethane glue fails, the staff will rotate the circular mounting rod half a circle, then retract the output shaft of the linear electric cylinder, and then pour the glue thickener into the polyurethane glue with unqualified viscosity to make the polyurethane glue more viscous, thereby increasing its astringency; then start the servo motor B to mix the polyurethane glue and the glue thickener, so that the staff can carry out the next step of processing on the polyurethane glue after production according to the addition ratio of the glue thickener to ensure that the viscosity of the polyurethane glue meets the production requirements; when the polyurethane glue remaining in the polyurethane glue storage cover needs to be cleaned, the staff will pull the movable cleaning disk through the two rectangular slots to scrape the inner wall of the polyurethane glue storage cover, which is beneficial to improve the cleaning efficiency of the polyurethane glue storage cover.

[0025] 3. The arc-shaped collecting box of the present invention collects the polyurethane glue dropped during the test, making the test area tidier; when the circular mounting rod rotates, the rectangular scraping plate can automatically scrape the polyurethane glue remaining at the bottom of the viscosity test plate, avoiding the residual polyurethane glue from affecting the accuracy of the next viscosity test, making the next viscosity test more accurate;

[0026] In addition, the provision of two supporting springs B ensures that the top of the rectangular scraper plate can always be in elastic contact with the bottom of the viscosity test disc, so that the rectangular scraper plate can have a good cleaning effect even after long-term use; when the arc-shaped collection box needs to be cleaned, the staff can remove the collection connecting frame, and then insert the rectangular scraper plate into the arc-shaped collection box, and then move the rectangular scraper plate in the arc-shaped collection box to quickly clean the inner wall of the arc-shaped collection box.
