Description
Technical Field
The invention belongs to the technical field of tobacco processing, and particularly relates to a method for determining the temperature of an electric soldering iron for cigarette paper joint.
Background
The cigarette strip forming link in the cigarette production process is that cigarette paper lap glue is quantitatively and uniformly applied to a cigarette paper lap position, then the lap part is fully attached through a pressing plate, and the cigarette paper lap glue is solidified and bonded under the heating action of an electric iron to form a finished product cigarette. The bonding effect of the cigarette paper lap adhesive is highly related to the temperature of the lap electric iron; when the temperature of the lap electric iron is lower, poor adhesion conditions such as air leakage, edge warping, mouth explosion, unevenness of lap and other appearance quality defects are easy to occur on the lap of the cigarette paper; the quality defects can not occur at higher temperature of the lap electric soldering iron; therefore, in order to ensure the bonding effect of the cigarette paper lap adhesive, the problem that the temperature of the lap electric iron is set to be higher exists all the time. The temperature is set to be higher, on one hand, the cigarette paper lap adhesive is easy to thermally crack, harmful components are generated in cracking products, and the upper limit requirement exists on the temperature setting of the lap electric iron aiming at different cigarette paper lap adhesives; on the other hand, the temperature of the lap electric iron is set to be too high, so that the water dispersion loss of the finished product cigarettes is easily too large, the water content of the finished product cigarettes cannot meet the requirement of quality standards, and the appearance quality defects of hardening and reflecting of the cigarette paper at the lap position can also occur; therefore, the temperature of the lap electric soldering iron is provided with an upper limit. The lower limit temperature of the cigarette paper lap adhesive is generally determined by the adaptability of the lap adhesive machine; the upper limit temperature of the cigarette paper lap adhesive is generally determined by combining analysis of the release amount of harmful components from thermal cracking of the cigarette paper lap adhesive.
The moisture content of the finished product cigarette generally has a determined numerical requirement, and the moisture content of the finished product cigarette of the current standard is required to be 12.4 +/-0.3 wt%. In order to ensure that the moisture content of the finished product cigarette reaches the requirement, the moisture content of the supplied cut tobacco is generally slightly higher than the value, and in the cigarette strip forming link, the lap electric soldering iron can solidify and bond the lap glue of the cigarette paper at a proper temperature and ensure that the moisture content of the finished product cigarette is close to the value as much as possible. However, the moisture content of the supplied cut tobacco often fluctuates, the temperature setting of the electric soldering iron at the joint of the production site is often set according to experience, so that the moisture content of the finished product cigarettes often fluctuates and even fluctuates greatly, the moisture content of the finished product cigarettes cannot meet the requirements of technical standards, and the stability and consistency of the moisture content of the finished product cigarettes between batches and between machine stations cannot meet the requirements. According to the experience of technicians in the field, when the moisture content of the incoming cut tobacco is higher, the temperature setting of the on-site electric soldering iron is also higher, so that the water dispersion loss of the incoming cut tobacco is higher, and the moisture content of the finished product cigarette is ensured to be within the range of standard requirements; similarly, when the moisture content of the incoming cut tobacco is low, the temperature setting of the on-site electric soldering iron is also low, so that the water dispersion loss of the incoming cut tobacco is low, and the moisture content of the finished product cigarette is ensured to be within the range of standard requirements. The temperature of the conventional lap electric soldering iron is set by field operators according to experience of the moisture content of incoming cut tobacco, the quantitative relation between the moisture dispersion amount of the incoming cut tobacco and the temperature of the lap electric soldering iron is not existed, the moisture content of finished cigarettes cannot be determined, and the moisture content and other indexes of the finished cigarettes still have large quality fluctuation, so that certain difference exists between different machines or between quality control of the same cigarettes produced by the same machine at different time periods.
The present invention has been made to solve the above problems.
