- Dec 28, 2020-

Background technique:


At present, the measurement and control of the pH of the glue tank of the domestic nitrile glove production line are all manually intermittently measured and adjusted, which leads to the hysteresis of the adjustment, which easily causes the pH of the glue tank to fluctuate, resulting in instability of the nitrile glove, and possibly The nitrile latex flocculates, causing pinholes in the nitrile glove. The online debugging of the glue tank PH is an important indicator to ensure the quality of gloves. Nowadays, IT automation is the mainstream trend, which has greatly promoted the development of the processing and manufacturing industry. Enterprises urgently need to improve the degree of industrial automation within the industry, so as to save labor costs and improve industrial automation. However, there is no automatic device that can automatically measure, control and adjust the PH of the glue tank in the prior art.


In order to improve the existing technology, people have carried out long-term exploration and proposed various solutions. A finger-thickening nitrile glove production line includes a first glue tank, a second glue tank, a mold and a moving device. A third glue groove is provided, the shape of the third glue groove is adapted to the finger shape of the nitrile glove, and the position of the third glue groove corresponds to the finger position of the nitrile glove of the second glue groove.


Although the above solution solves the shortcomings of the existing technology to a certain extent, it cannot automatically measure, control and adjust the PH of the glue tank, and the overall design is not reasonable enough.
