As is known to all, the board bending is the main obstacle of all carton factory. It will affect the operation of the system, such as die - cutting, printing, and so on, will result in increased scrap cardboard, so that the work is not smooth. Before we have written on the bending and S bending of the solution, there is a bending and they are not the same, that is, the board appears to be a distorted state, showing irregular bending. This is how to form it? In fact, it can be checked on the paste roll and cotton with two aspects of the reasons and solutions to find. 1 Top paste In the production process, the equipment is a vibration. If the paste roll in the circumferential direction of vibration, it will cause the paste is not uniform, resulting in different water content of the board, forming a distorted phenomenon. Encountered such problems will have to repair the vibration of the paste roll or replace. Secondly, the paste on the bearing wear will cause uneven paste, resulting in distortion, then replace the bearings will be able to solve. Therefore, equipment maintenance is very important. 2 cotton belt In the production process of tile line, synchronous production is very important. When the double machine cotton belt tension at different times, under the cotton belt speed will not synchronous, making paper and paper in the cardboard uneven force, then it will cause the distortion of cardboard. We can adjust the tension of the cotton belt, so that the upper and lower cotton belt synchronous operation. From the above two points of analysis, the board appears to distort the state on the device that we have defects. Therefore, the plant must often carry out inspection and implementation of the equipment, the weekly, monthly, quarterly, annual maintenance, to ensure the normal operation of equipment, to avoid equipment failure caused by product accidents.

To reduce the cost of carton forming process, we must first pay attention to product quality, quantity, a time to do a good job in the quality of the carton, a number of times to do enough, the quality of the carton to meet customer requirements. The second is from the equipment, process technology, staff operations, management of the several aspects of the comprehensive consideration. The following as long as from the "equipment" to proceed with the description! Printing machine, nail box machine, packing machine and other equipment selection should be selected according to the order characteristics, if long single daily orders more, on the choice of high automaticity and high precision equipment, and proper configuration of several stand-alone, for the production of single or small number of short order, can reduce production cost; when the total number of short single orders for most of the time, you should choose a single production, or even semi automatic equipment, for example, carton orders on average in southern Zhejiang in 50 only to 200, apparently with the automatic equipment equipment performance is not The loss outweighs the gain., to play well, it is a waste. The following equipment selection must be considered: Printing part: 1, feeding the maximum and minimum width; 2, the largest printing area; 3, the use of plate thickness; 4, the number of the wire coating roller; 5, the number of printing roller; 6, the maximum and minimum thickness of paper; 7, guide way; 8, the printing precision; 9, printing speed; 10, the degree of automation control system; 11, with electric power. Slotted part: 1, the maximum and minimum slot depth; 2, slotting phase adjustment precision and automation degree; 3, the thickness of blade; 4, the replacement of slotted knife is convenient; 5, slotting speed; 6, supporting power. Nail box part: 1, through the maximum size of the box, the smallest size (length * width); 2, after the thickness of the box blank; 3, the use of flat type; 4, nail box speed; 5, nail distance; 6, power. Packaged part: 1, maximum and minimum width; 2, pack the largest and smallest thickness; 3, the use of packing rope material; 4, packing buckle mode; 5, packing speed; 6, equipment power.

1, set the goal of tile line equipment: normal speed of about 90% Such as tile line design speed of 250 m / min, the normal target production and speed should be: 220 five m / min, 230 layer three m / min. 2. Find the corresponding process parameters of temperature and glue physical index to match the target production speed. Such as the temperature range of each piece of paper and the corresponding temperature, viscosity and solid content of the glue. At present, most of the factory's temperature control is based on the operator's experience of manual control. The ability of the operator and the responsibility of the heart is very high. The temperature control of the wet part of the tile line is recommended ". 3, optimize the order structure, improve the scheduling of single program to reduce the impact on the efficiency of production. 4, to participate in the production of staff management assessment, to mobilize the enthusiasm of the staff involved in management Note: the management responsibility to the people (loss, quality, efficiency, 6S), do not eat rice pot. 5, all the factors affecting the efficiency of records, analysis, find reasons, research solutions Such as: 1) stop, broken paper, paper, paper jam, fault reason, and so on, roll change time; 2) have poor quality such as quality problems of Gao Kezhong base drive fast speed or high speed; 3) wet for a single short length, the paper is not urgent, such as the length of less than 500m; 4) cadres for a single length short, continuous small orders, small orders, cadres cut long for a single slow; 5) logistics system can not keep up the speed; 6) operator and coordination ability. 6, repeat the process, the formation of a virtuous cycle.

In color printing, sometimes we often encounter problems and this version of the plug, often for the quality and efficiency of color printing production have certain adverse effects. Generally speaking, color box printing are often large customers, such as pharmaceutical, drug in white box, color box these large orders, once the plug version will increase the number of downtime, resulting in low production efficiency, but also will increase the loss of printing production. So what is the cause of the plug version of the problem? We usually find the ink and the print version, as well as the operation caused by the plug version. First, the reasons for printing ink 1, when the production of color printing ink liquidity is bad. Some operators love into the cartridge ink to adjust slowly, let roller and rollers inking more intermediate storage. This approach is applicable to the full version of the printing, but the printing dot or small word will appear in the plug version of the problem. Solution: to speed up the flow of printing ink, adjust the pressure of the ink pump. 2, printing ink drying too quickly, when the ink from the transfer roller to the printing plate, printing paper box and then transferred to the time, because the ink drying too quickly, the accumulation of ink in print edition plug problem. Solution: when you rub the printing plate, you can add a new ink or add a slow drying agent. 3, printing ink viscosity is too high will cause the plug version, to control the printing viscosity, general viscosity control in 9 seconds or so more appropriate. 4, printing ink in the dust and paper powder, will form the plug version of the problem. The filtering net is additionally arranged in an ink inlet tube, mesh 120 mesh in it. Reason two, printing plate roller, and Does not match the print and roller, such as 300 to 80 line roller printing pattern, then this ratio would constantly plug version, because the net 300 net hole is too large, the amount of ink transfer assembly cause the printed version of the ink, printing dot plug caused leading print edition. And the roller does not match. Solution: usually the ratio of 1:4.5, the ratio is reasonable. Three, the reasons for the mistakes of the operation of the printing staff The printing operation, the main roller is too much pressure as a result of deformation caused by printing, printing dot gain, resulting in network congestion. Color box printing manufacturers to conduct professional training for operators, printing version printing operation to prevent plug caused by failure.
