Emphasis on the production capacity of tile lines in detail

Production efficiency is an important manifestation of corporate technology and management. The world giant of the world's automobile manufacturing industry, Ford Motor Company, is relying on the efficiency revolution to take off. Making full use of the production efficiency of corrugated cardboard lines, although far from being able to reach the level of efficiency revolution, it is still a very important issue in terms of the current actual situation. It is related to the improvement of labor productivity of enterprises, the reduction of production costs, profitability, and the improvement of organizational efficiency.

Then, what is the production efficiency of tile lines? We think that it is the output of square meters per unit time. It can be calculated in m2/hour or m2/class. The current production efficiency of tile lines generally fails to reach the designed production capacity. For example, a lightweight tile line designed to produce 23,000-30,000 square meters per class, that is, the hourly output should be around 3000m2. But now it is generally around 1500m2, and the production efficiency should be doubled at the current level. In this way, the appearance of the enterprise can be greatly improved. Then, how can we give full play to the production efficiency of tile lines? Overall, it is a comprehensive factor and a comprehensive reflection of the quality of business leaders and workers. Specifically, we must do the following:

1. We must do a good job in preparation for production. This is the basic work to increase production efficiency. Preparation is not in place, the equipment is not in good condition, and it is not easy to boot. For faults and hidden dangers, they must be excluded from preparation. Operators, captains, and workshop directors are all familiar with the state of the equipment. If they are innumerable, they are guilty of dereliction of duty; because preparations are not adequate or careful, resulting in midstream shutdowns, they must carefully find out the reasons and strictly investigate responsibilities.

2. Maintain a balanced production of corrugated cardboard lines. The so-called balanced production means continuous production without stopping the machine. Stopping in the middle of the road means that the production operation is not normal, which will greatly reduce the production efficiency. It will not only produce a large number of defective products, but will also reduce the product quality.

Balanced production requires all employees to be skilled, superb technical skills, and responsible, meticulous work. In production operations, operators must devote themselves to paying close attention to the operation and trends of equipment and paper. Correctly deal with various special situations in a timely manner to ensure the normal operation of tile lines.

Tile line production and operation in a balanced manner, should be based on double-sided machine, coordination and coordination, step by step: if the speed of the single-sided machine, the amount of alignment on the bridge to be coordinated, in general, the arrangement of single-sided cardboard on the bridge is to account for 2/3 long is appropriate. The single-sided machine may appropriately accelerate and appropriately increase the amount of single-sided machine boards stacked on the bridge before the paper change. At this time, the double-sided machine and the other single-sided machine must be properly decelerated to achieve effective cooperation. Change the paper faster, and the new paper will go up within one minute. When the paper change is over, all lines resume normal speed.

3. Give full play to the tile line process performance. This is obvious for the full utilization of tile production efficiency. For example, in a production line of 1600, a production of 1200 paper webs is more efficient than using 1600 papers, and the production efficiency is reduced by 25%. Therefore, when arranging production tasks, we must be very cautious about the specifications of the products and their materials. We must, in line with the principle of exerting the production efficiency of tile lines, make appropriate adjustments and collocations for some small-size products and arrange them scientifically.

4. Give full play to the thermal efficiency of the boiler and ensure that the tile line has sufficient vapor pressure. This is an important condition for giving full play to the production efficiency of tile lines. The relationship between steam pressure and tile speed is shown in the table below.

It can be seen from the table that the steam pressure is directly proportional to the tile speed. To fully utilize the tile line production efficiency, it must be ensured that there is sufficient steam pressure. For example, a light tile line, which requires a vapor pressure of 0.9-1 Mpa, if the production of double-sided five-layer paperboard, steam pressure should also reach 1-1.2Mpa. In the practice of producing five-layer paperboard, the steam pressure is 0.8, and the double-sided machine speed cannot be greater than 800r/min. Steam pressure 1-1.2, double-sided machine speed can be greater than 1200r/min, its efficiency increased by 50%. Therefore, steam pressure is an important factor in tile line production efficiency.

The full utilization of boiler thermal efficiency depends on the good condition of boiler equipment. Its operating system must meet the requirements of technical standards, high-quality fuel coal, and skilled service technicians. At the same time, the siphon pipes, steam separation stations, and return pipes of the tile-line heat rollers are kept in good and smooth condition, which is also very important for the full use of steam thermal efficiency.

Note: The "tile speed" varies from model to model.
