Description

Technical Field

[0001] This application relates to the field of equipment technology for water-based adhesives for tobacco, and in particular to a pH value measuring device for water-based adhesives for tobacco. Background Technology

[0002] In the tobacco production industry, water-based adhesives for tobacco products are crucial materials for bonding filters to cigarettes and packaging paper. Their pH value plays a decisive role in the adhesive's viscosity, stability, and environmental friendliness. A pH value that is too high or too low not only affects the bonding strength between the adhesive and tobacco materials, leading to quality problems such as filter detachment and packaging wrinkles, but may also release harmful chemicals at high temperatures, threatening product safety and consumer health. Therefore, accurately measuring the pH value of water-based adhesives for tobacco products has become a core step in ensuring the quality of tobacco products.

[0003] In practical use, it has been found that most traditional detection devices are only equipped with simple pH electrodes and data display units, completely lacking a stirring mechanism. Due to the high viscosity and complex composition of water-based adhesives for tobacco, the additives and acid-base components in the adhesive are prone to uneven local concentrations when stirring is absent. This results in the area contacted by the measuring electrode failing to represent the true pH value of the entire adhesive, leading to serious distortion of the measurement data. Therefore, we propose a pH value measuring device for water-based adhesives for tobacco to solve the above problems. Utility Model Content

[0044] In this application, during operation, the water-based adhesive for tobacco is first injected into the mixing tank 1 through the feed pipe.
