Best scheme for the hottest paperboard production

The best plan for paperboard production

with the increasingly fierce market competition and the recent rising prices of raw materials, business operators have tried every means to make the company grow continuously. Therefore, as long as it is possible to improve the current operating conditions by purchasing new equipment and improving management methods, everyone is racking their brains to make breakthroughs and strive for the survival and development of the enterprise

a person in the packaging industry once described the current packaging market as follows: in the past, when recruiting salespeople, they had to train how to calculate the area of cardboard and cartons, and how to add the cost of raw materials to the basic processing fee is the unit price for customers: now! The salesman only needs to answer the customer. Can he accept the order at a lower price than the current one? Can we reduce costs? Is it profitable? Indeed, in an era when all walks of life are shouting "costdown", it seems that no one will listen to how you calculate the unit price, because guests just want to know immediately whether you want to do this price. Anyway, if you don't do it, people who want to do it are still waiting in line. If you hesitate a little, the order will be put into others' arms immediately. This reality points out the dilemma of the current packaging industry

but just when the market seems to have been howling everywhere at the same time, I am here to choose an experimental machine with superior performance and good quality from another perspective and put forward another kind of thinking. I hope you can face up to and think about a problem -- when we want to seek profits from customers, but sometimes we don't give them, can we also turn to ourselves and kill a glimmer of vitality from raw material control and efficiency improvement? 9 the previous idea was to expand equipment and increase production capacity to share costs and accumulate profits quantitatively. But now the market is basically the so-called "terror balance". When the production capacity of large manufacturers is expanded, because the market demand has not increased significantly, small manufacturers must reduce prices to survive. As a result, the profits of the whole market are thinner, and the quantified profits are worse than the original

after obtaining the approval of Chen Rong, general manager of Huangyan ricundai carton factory in Taizhou City, Zhejiang Province, I will introduce how Huangyan Shidai carton factory can break through the current situation and create new opportunities in the market. First of all, Huangyan Shidai carton factory has a good reputation in Taizhou, Zhejiang Province for 15 years. Four years ago, it bought a set of domestic Hubei Jingshan 1. The 6-meter paperboard assembly line includes two single-sided machines, one double-sided machine, one Slitter, and two crosscutters. Under the comprehensive factors of raw materials, equipment conditions, and personnel operation, the original daily production status of the plant is more important because this project will become an important experimental field for China's No. 5 mining industry to deepen the reform of state-owned enterprises. The basic conditions are as follows:

◆ daily paper speed: about 70 meters/minute

◆ average good, so as to achieve a decentralized average of 1 CDs@MOF Speed of composite products: 40 m/min {actual length of good products/(production + total parking hours))

◆ daily paper consumption: 8% (bad paper + excessive production) Length/total paper consumption

in the face of such a low profit market, like all manufacturers, Huangyan era has repeatedly considered and calculated whether to invest in higher speed production equipment in the past year. After many discussions, evaluation and comparison, it was decided to use the production management system of the corrugated machine assembly line first, hoping to improve the current production status of the paperboard line with this set of auxiliary equipment

after two months of use and commissioning, the on-site operators have been familiar with the use of the new equipment. At this moment, the production situation is checked again, and there is indeed a significant improvement. Daily production: the situation has changed as follows

◆ daily paper speed: 100 meters/minute

◆ average good product speed: 65 meters - 0 meters/minute

◆ daily paper consumption: less than 4%

that is to say, after two months, the production capacity of the factory has increased by 50%, and the consumption is only 1/2 of the original. Why is it that a set of production management system is added to the original mechanical equipment, but such amazing changes have taken place? 9 what functions does this set of equipment have? Can it play such a big role? Next, I will introduce the functions of the production management system, which is very helpful to improve the efficiency of the production line:

I. Office part:

using the remote online function provided by the production management system, the supervisor can fully grasp the production status of the workshop in the office, and the order setter can transmit the data to be produced to the production line through the computer, especially in the case of emergency order insertion or data modification, it can achieve the effect of timely processing, which greatly improves the work efficiency. Through the daily production report, we can analyze which link of the production process needs to be improved and can be done better

II. Production line:

several common conditions at the wet end that are easy to increase consumption and reduce efficiency:

1. During manual operation, the speed allocation is unstable and the overpass is not well controlled, which is easy to break the paper and cause parking

2. Manual speed regulation changes too much, which is easy to produce machine vibration and poor paste caused by unstable quality

3. Manual paper calculation is not accurate enough, causing the master to always take more paper to avoid insufficient quantity, resulting in more orders and unnecessary waste

4. Because the staff is responsible for operating the equipment and estimating the length of paper, the quality and production efficiency cannot be improved

however, the production management system provides functions such as "synchronization", "automatic paper receiving" and "Overpass control". Through the high-speed calculation and memory ability of the industrial computer, it coordinates each single-sided machine in the wet end to control the stacking amount of the overpass in the most intelligent way according to the paper stacking condition and motor characteristics of the overpass, and ensures that the single tile paper will not have poor quality due to excessive vibration. In addition, under the condition of no automatic paper receiving machine and automatic speed reduction, the paper can be successfully changed within 3 meters by completing five paper receiving heads at a speed of 30 meters/minute. It achieves the function of timely and appropriate amount

general manager Chen Rong said that at present, the production control at the wet end is better than that of the original masters, which is far beyond his expectation. And now the master at the wet end has more time to use song to pay attention to the improvement of quality and the cleaning and maintenance of the machine, instead of having to do too many things alone, as in the past, people are busy and things can't be done well. In the cadre end, due to the configuration of the mode of double crosscutting machine, it used to be necessary to stop the slitter for 3-5 minutes to adjust the tool spacing, and then continue production. Such action will always cause a loss of about 3 meters, and the efficiency will also be sacrificed. However, after installing the production management system, the production management system can automatically select the best running speed according to the material condition, and cooperate with different alarm sounds and warning lights to predict whether or not; If the size of the slitter is changed, whether to change the order of the crosscutting machine? It will automatically slow down and stop through the production management, and automatically return to the maximum operation speed of the order after the order change is completed. Such a process, however, really ended the past 3-5 minute downtime for each order change and the nightmare of more than 3 meters of bad paper by taking less than 20 seconds and less than one meter of bad paper

indeed, spicy peppers don't have to be big. How the packaging industry competes in quality, service and cost should be a problem worth pondering. It may be a thousand things for the company to improve its competitiveness, but at a time when the profit is as thin as paper, have you ever thought that as long as you really find a good way, small soldiers can also make great contributions
