Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive maturity detection, in particular to an automatic adhesive maturity detection device. Background Art

[0002] An important indicator of viscose fiber is maturity, which is used to indicate the colloidal stability of viscose. The principle is to use ammonium chloride to titrate the viscose to make it coagulate. The minimum value of ammonium chloride required is the maturity of the viscose, which is expressed in milliliters of ammonium chloride solution consumed.

[0003] At present, when testing the degree of maturity, it is necessary to weigh 20g of viscose on a balance and put it in a 150ml ripening cup, add 30ml of distilled water and stir evenly, then titrate with 10% ammonium chloride solution and stir quickly and evenly. When the viscose begins to solidify, it means the end point is coming. Draw an arc on the surface of the viscose with a glass rod. When the arc of the viscose surface is obvious, it is the end point. Write down the number of milliliters of ammonium chloride solution consumed, which is the result of the degree of maturity. Since the whole process is manually operated by personnel, there are many factors that affect the results, such as: stirring speed, stirring strength, ammonium chloride addition speed, end point judgment, and judgment of the clarity of the arc drawn on the viscose surface.

[0004] At present, the viscose fiber industry still uses the sampling method of manually stirring and then judging the maturity of the viscose by scratching. In order to reduce the influence of human factors on the sampling results, although all companies have unified the sampling techniques, differences in sampling techniques still exist due to the differences in sampling personnel. Even if the same person repeats the sampling within a day, there will inevitably be differences.

[0005] The Chinese patent with publication number CN110487675A and publication date 2019.11.22 discloses a device for detecting the maturity of adhesive, including a base, a vertical pole, a stirring motor, a stirring rod, a stirring blade, a motor chuck and a burette clamp. A vertically upward vertical pole is fixedly installed on the base, and a motor chuck that can move up and down on the outside of the vertical pole is provided on the outside of the middle part of the vertical pole. A stirring motor is fixedly installed on the motor chuck, and an output shaft is provided at the lower end of the stirring motor. The lower end of the output shaft is fixedly installed with the upper end of the stirring rod, and at least two stirring blades are evenly distributed along the circumference of the outer side of the lower end of the stirring rod; a burette clamp that can move up and down on the outside of the vertical pole is provided on the outer side of the lower part of the vertical pole; a control unit that can collect and display the current signal corresponding to the stirring motor maintaining a constant speed is provided on the outer side of the upper part of the vertical pole, and the stirring motor and the control unit are electrically connected together. The patent has the following disadvantages: 1. There is no titration control measure, and manual titration is required. When the current determines that the titration is over, it needs to be stopped manually, there is an error, and automatic control cannot be achieved. 2. The controller has no reading display, and the consumption of 10% ammonium chloride aqueous solution needs to be read manually, which has errors. 3. When performing parallel sample testing, the previous sample needs to be tested before another sample is tested. The time error will affect the test results. Utility Model Content
