Corrugated box production cost reduction solution three

2. By improving gap control (supplying roller to corrugating roller, feeding roller of container scraping roller pair), the surface of the roller is optimized (fine grid engraved mode), and the double-sided machine paste unit uses pressure shoe loading technology; The use of higher solids in the starch paste can make the paste on the paper web more uniform and make the paperboard smoother. The above improvements will reduce the total amount of glue used by 3 grams per square meter.

3. In order to produce a smoother paperboard, the properties of the base paper and the starch paste must meet the specifications of the equipment characteristics. Standardize and improve the humidity of the base paper, control the humidity difference on the surface of the paper web within ±1%, and improve the paper fiber orientation and average paper thickness; control the solid content of the starch paste to 25-28%, which is better Adhesion. The improvement of the flatness of the cardboard makes the subsequent processing machinery faster and produces less waste paper.

4. The improvement of the splicing machine, the control of the web tension, the automatic continuous material and the rapid order switching, the sigma-type switching and the direct-drive cross cutter, etc., reduce the waste paper by 2-3%.

5. Reduce operators and reduce personnel costs, each shift can reduce 3-4 operators, reduce labor costs.

6. Improve the average output (square meters per hour) of corrugated board production lines while reducing costs.

(1) Increase the equipment width of the corrugated board production line, which can increase the average output and the efficiency of the paper frame;

(2) Increase the design speed and fully automatic mode of the corrugated board production line. Can also increase the average speed;

(3) The average annual increase in the output of corrugated board products is 3 to 4% in industrialized countries, which will result in more than twice the market.

7. In addition to the artistically designed corrugated cardboard production line, improvements in other automated production models were introduced into the carton industry at the same time; the improved logistics system of the product design system as well as the fully automatic and upgraded processing machinery will be gradually completed.

8. Temperature and pressure are of great importance in the production of corrugated board. The surface temperature of the hot plate must reach 170°C when the production speed is 80m/min. The faster the temperature, the higher the temperature, so that the raw rubber reaction matures.

9. Carton enterprises adopt the latest technology and complete the same output of the traditional three shifts in a two-shift system, which will bring a lot of cost advantages. Each year 600,000 m2 per person (according to the specific product form), as a major productivity evaluation standard (million per person per year). (Text / Chen Xirong)
