Manufacturing techniques and production process in die-cutter

Shandong Century Machinery Co.,Ltd is a high-tech enterprise specialized in post-printing equipment that gathered scientific research, production sell as a whole.Our company has been passed ISO9001 quality certification and CE quality management system authentication.Die - cutting equipment characteristics and development trendsWith the improvement of people's living standard, packaging products are also rapidly updated. Current packaging products, especially some cartons and cartons with special s and special shapes, are no longer able to meet the changes of the market and users' demand for packaging according to the ordinary production methods. As carton manufacturers, they should keep up with the market demand and strive to meet the ever-changing consumer market. At present, many carton enterprises in the actual production of die-cutting carton, the existence of some technical problems can not be well controlled to solve, thus unable to ensure product quality, affecting the economic benefits of enterprises. This issue we will discuss with you from different aspects of the die-cutting process, problems, solutions and technology trends.Knowing die cutting processDie-cutting process is the most commonly used to package press work a process, is to use die-cutting knife according to the product design requirements of the pattern combination of die-cutting, under the action of pressure, the press work or other plate shape blank rolling cut into the shape or cutting mark of the molding process. Indentation process is the use of line pressure knife or die, through the role of pressure in the material on the line, or the use of line roller in the material on the line, so that the material can be predetermined position bending molding.Usually die cutting indentation process is the die cutting tool and line tool combined in the same template, at the same time in the die cutting machine die cutting and indentation processing process, referred to as die cutting.Technology introductionDie-cutting indentation of the main process as follows:On the plate - adjustment of pressure - a certain rules - paste rubber strip - pressure die - cutting - cleaning - finished product inspection - a number of packaging.(1) version: first, proofread the die-cutting version has been done, roughly observe whether the requirements of the design draft. Steel line (line pressure knife) and steel knife (die cutting knife) position is accurate, slotting hole knife line whether to use the whole line, line corner is rounded; In order to facilitate waste removal, whether the adjacent narrow waste side connection increases the connecting part and makes it connect into a piece; Whether there is sharp Angle phenomenon at the junction of two lines; Whether there is a sharp line cut off the middle paragraph of another line, such as the problem. Die-cutting once the above problems, should immediately notify the plate making personnel to correct to avoid more time wasted, and then, the production of the die-cutting version of the installation fixed in the die-cutting machine, the initial adjustment of the position of the good version.(2) adjust the pressure, determine the rules and paste rubber plug: adjust the layout pressure, first to adjust the pressure of the steel knife. After pad paper, first turn on the embossing for several times, so as to flatten the steel knife, and then use the cardboard larger than the die-cut version of the pressure test, according to the steel knife cut in the cardboard, using local or all gradually increase the pressure or reduce the number of layers of the lining paper to make the layout of the knife line pressure uniform.In general, the steel wire is 0.Bmn lower than the cutter wire (because of the different corrugated board, the thickness difference between the cardboard is large, should be adjusted according to the actual situation). Usually according to the thickness of the die-cut cardboard to calculate the thickness of the pad, that is, the thickness of the pad paper two steel knife height a steel wire height - the thickness of the die-cut cardboard.Rubber cartridge plug should be placed on the two sides of the die-cutting version of the main steel knife base, the use of rubber cartridge good recovery effect, the separated cardboard from the edge. In general, the rubber strip should be higher than the die cutting blade about 1.2mm, the rubber strip from the knife line distance of 1mm-2mn is advisable, because if installed close to the body of the knife, the rubber plug in the pressure can not expand in the direction of the body, can only expand in the other direction, die cutting knife has not cut off the paper, has been rubber plugRaw wool.(3) pressure die cutting, positive pressure die cutting, waste cleaning, finished product inspection, points packaging: after the above work is completed, should first die cutting sample, a comprehensive inspection to see whether the indicators meet the requirements. The batch production can be carried out after the sample is signed and confirmed by the full-time inspectors. In the process of production, the operator should carry out white inspection from time to time. It is mainly compared with the sample sheets to see if there are problems and solve them in time. After the die-cutting products should remove the excess material, and then burr on the edge of the burr, make it ooth without burr. Then the finished products were selected and inspected, and the defective products were removed. Finally, the products were counted, packaged, accepted and put into storage.Equipment characteristics and development trendUsed for die-cutting indentation processing equipment known as die-cutting machine, according to the die-cutting version and die-cutting structure of the main parts of the shape is different, there are currently three types of die-cutting machines in the market: flat die-cutting machine, rotary die-cutting machine and rotary die-cutting machine. But no matter what type of die - cutting machine, its structure is composed of die - cutting table and press paper mechani. Here's a brief look at how they work and their pros and cons:Flat die-cutting machineWorking principle: flat - die - cutting machine die - cutting table and the shape of the cutting mechani is flat. Die - cutting plate is fixed on the flat plate, the plate is processed on the pressure plate (pressure plate). When working, die cutting table fixed, the pressure plate through the crankshaft connecting rod reciprocating movement, so that the plate and the pressure plate constantly clutch pressure, each pressure will achieve a die cutting. Common flat die - cutting machine has vertical die - cutting machine and horizontal die - cutting machine. At present, the vertical die-cutting machine is mainly made up of flat presses; And the horizontal die-cutting machine structure and monochrome offset press similar, it is composed of feeding part, molding part, part of the material, some with automatic waste removal device.Advantages and disadvantages: due to the flat die cutting machine relative to other die cutting equipment has a simple structure, easy maintenance, easy to operate, easy to replace die cutting indentation version, suitable for different grams of material, die cutting precision and a series of advantages, so it has a wide market. However, its disadvantages are also obvious. For example, it needs a lot of pressure when working, which leads to high labor intensity and low production efficiency.It has a wide range of application, suitable for folding carton, paste carton, corrugated carton die-cutting indentation treatment, is the current domestic use of more common die cutting machine.Die cutting machine operation must pay attention to whatBefore operating the machine, the operating performance and procedures of the machine must be fully known. You can't operate without training.According to production requirements, get the corresponding knife plate and plastic plate and other materials. Check that the machine and its surroundings are in good condition before turning on the main power.After starting the machine, the upper board should be taken out first, the knife board to be used should be fixed on the standard of the board board, and then the operating table should be pushed in and locked.Then take out the lower platform, put it on the upper platform relative position paste on 1-2mm thick high quality plastic board, after that push operation platform also want to lock.Test the pressure until the pressure is balanced. Then lock the dart wire and keep the pressure still. Pressure adjustment as light pressure fine tuning.Maintenance of die cutting machineFirst of all, the staff to do a good job cleaning dust.Because in the actual work, there will be a lot of waste paper edges, paper wool, if you are not careful will enter the chain drive parts, die cutting parts moving platform and some rotating parts, causing machine failure. Therefore, the die - cutting machine cleaning should be put in the first place, and then make sure that the machine is trouble-free.Secondly, die cutting machine to change oil regularly. Die cutting machine main action is the main motor to drive the sliding rod, pulley to drive other parts of the operation, high-speed work speed can reach 6000 pieces per hour if the lubrication is bad is very troublesome.
