Rising raw material prices promote adjustment of fittings and energy saving of tile lines

For carton factories whose raw material prices are rising, the purchase of new lines is undoubtedly a large investment. Now that the profits from making cartons are low, it is a wise choice to transform the corrugated cardboard production line. Some paper mills have passed through the tiles. After the transformation of the line equipment, the average speed of the transformed equipment was increased from the original 70m/rain to about 90m/rain. Paste savings of more than 5%: base paper loss rate decreased by about 1%. More than 15% energy saving, cardboard flatness has also improved. The total investment in tile line reconstruction is less than RMB 300,000. The transformation of equipment will not only save costs for the company, but also win profits. At the same time, it also achieves the goal of reducing pollution in the production process and striving for environmentally friendly production.

Spring type pressure bar

The transformation of corrugated board production is very important. In order to solve the problem of excessive sizing on the double-sided sizing machine, some companies replaced the double-sided squeegee press roller with a spring-type touch bar. This kind of touch bar is designed to solve the problems that the traditional paste machine (paste machine) of the traditional corrugated board production line is prone to decrepitation and bad placement. Its design principle is The grouping platen and the spring apply pressure independently to the single-wall paper. Each piece of the platen depends on the spring to adjust the pressure between the paper and the paper itself. Ensure that the platen and the paper are affixed to the table to the maximum extent to ensure even paste. It overcomes the stumbling and staging problems caused by wear and deformation of the rider and paste wheel.臧 The effect of the irregular run caused by the original paper force on the quality of the paperboard was reduced.

The main characteristics of the touch bar ensure that the paste is even, so that the amount of paste to save 5% to 15%. The utility model can prevent tipping or flattening of the tip, can keep the corrugation well formed, ensure the thickness of the cardboard is even, and improve the strength of the cardboard. The main components are made of imported special steel and are installed rapidly, generally can be installed within 8 hours to 12 hours, and parts are replaced. Can be completed within 1 hour. After the installation, there is no need to make any adjustments to the production line. The maintenance is very simple. It can be kept clean with a high investment report rate. Generally, the investment can be recovered within 6 to 15 months.

After this transformation, the single-piece tablet can be automatically compensated and adjusted by the spring, so that the sizing section is always at the peak, so as to achieve the purpose of reducing the amount of sizing, maintaining the cardboard type, and improving the side-press strength of the cardboard.

Automatic expansion chuck.

In order to reduce production costs, some companies designed paperboard production line paper chuck remodeling projects. Replace the original hexagonal taper cartridge with an expanding cylindrical bipolar paper cartridge to avoid waste of paper and to balance the tension of the paper roll.

The feature of this self-expanding collet is that there is a problem that the cone-shaped paper collet breaks the base paper and the inner edge of the paper during use, resulting in difficulty in the use of the tail paper. The tail paper scrap rate exceeds 2%, and the automatic inflation occurs. The chuck does not require power assistance. After the paper is successfully cut, the ribs of the chuck tighten or loosen as the paper holder is traversed horizontally. The paper holder automatically expands and expands in the paper tube, and the fixed paper or automatic shrinkage is performed. Then, the paper is completely removed, completely solving the problem. Cone chucks will break the tail paper. Improve the utilization rate of 7 base papers, reduce costs, and use automatic expansion chucks to prevent slipping and more reliable tension control.

After the use of self-expanding chucks, the use of tail paper can reach a minimum of 40 kilograms per day and a maximum of 300 kilograms. Calculated at 1800 yuan per ton of paper, it can save 72 to 540 yuan per day, and can save 2160 yuan per month. 16,200 yuan, each year can save funds 25,920 yuan to 194,400 yuan. The steam helium condensate recovery system of the production line was installed. Through this system, the condensate and waste steam produced in the production line were pressurized by the piston-cylinder compression principle, and the water vapor mixture was directly pressed into the boiler to make the steam point for the boiler. And steam eyesight form a closed circulatory system, so that the purpose of saving energy to the maximum. After this system was modified, it saved more than 5% coal per month.
