The invention and development of the printing machine plays an important role in the spread of human civilization and culture.What is the difference between a printer and a printer?How to buy a printing machine?Lets take a look at the printing machine knowledge encyclopedia.
Application of printing machinery
When the printing machinery starts, the current of the motor will be 5-6 times higher than the rated, which will not only affect the service life of the motor and consume more power. The system will leave a certain amount of balance in the electrical selection during design.The speed of the motor is fixed, but in the actual use process, sometimes it is necessary to run at a lower or higher speed, so the frequency conversion transformation is very necessary.The inverter can achieve soft motor startup, the purpose of changing the voltage frequency of the device to achieve energy saving speed regulation, and it can provide the equipment with protection functions such as overcurrent, overloading, and overloading.
Although the Chinese printing industry still has many problems such as overcapacity, increased labor costs, large fluctuations in raw materials, large unscrupulous enterprises in the industry, small unspokenness, lack of technical and management innovation capabilities, etc.good.
Affected by the rapid growth of the market demand of inkjet printers, digital color machines and special imaging printing machines, the market size of digital printing technology is growing. The scale of the global printing equipment and equipment market is expected to reach US $ 2.122 billion in 2015.
How to buy a printing machine
1. Printing products: The product has convex surface, mostly uses a printer, and the plane and the rules are mostly wire printers.
2. Printing feel: If you want to touch the effect, you can use a wire printer.
3. Product area: You can choose a printing machine of different specifications according to the product size.Small area printing is mostly printer.Product layouts are relatively fixed, the number of printing is particularly large, the printing area is also large, and the layer of the layer is thick. The concave printing machine should be selected for printing.For prints with rich colors, layouts with large graphic printing area, products that are made of outlets, and products with irregular printed quantities, you can choose a flat printing machine for printing.
4. Selection of process: Multi -facial printers are obviously used, which can be more accurate for color; plastic products can be used to use a hot molmpoling machine directly; glass products need to be printed first before the ink is dried in ink.
5. Product types: Most of the toys and stationery are used in printers. Most of the cosmetics industry uses silk printers. Most of the bottle caps are used.
6. Equipment types: There are small varieties and large -scale professional production enterprises, usually buying large equipment.Multi -varieties of small -batch companies usually buy small and medium -sized equipment.Considering the amount of corporate funds, the corresponding high -end fine printing volume, the operator and management of the management, depreciation costs, imported supporting printing materials and parts and maintenance costs.
7. Equipment price: When purchasing, you must pay attention to multi -party understanding, inspection, and comparison, so that the production capacity and product printing quality of the purchased printing machine are not only guaranteed, and the price of machines is reasonable.
8. Check the trial: Check whether the appearance of the device and the parts are completely harmless, try whether various functions can play normally, whether the machine is complete, and so on.
Printing operation process
1. Before turning on: First check the machine, especially when operating a machine that has not been turned on for a long time or connecting someone elses machine, you should pay attention to this.
2. Putting on and running: Before turning on, you should first ring the bell. Before the switch is run, the other hand should be placed on the town switch urgently.Usually, the machine should be carried out when the surface of the upper version, rubber cloth or cleaning the roller.
3. The water ink: the amount depends on the specific print, the general water and the amount of ink are slightly larger than the actual needs.
4. The upper version and the rubber cloth: The rubber cloth should generally be installed in advance, and the installation of the printing version should be performed in the presses.Before the previous version, check the printing version in detail.
5. Water and uniform ink: Move the machine, make the water and ink enter the water and ink roads, and beat them.
6. For the rules: the paper used at this time should be found to find the rules. The usual method is to find some white paper in the abolition of the seal.Note that the wheel paper should be consistent with the white paper to be printed (amplitude, quantitative, category) until the rules are right.
7. Analysis of the accuracy of the chapters: It is impossible to achieve the ideal overprint. Usually, the accuracy that people can accept.
8. Find ink color: The ink color should be evenly consistent. The common method of adjusting the ink color is to change the amount of ink.
9. Formally printing: First of all, the proofs of the school, and hand over the printed proofs to the relevant responsible person for review.When entering genuine printing, samples should be taken frequently to observe the balance of water and ink.When printing, you must diligently stir the ink fight, look at the water fighting, and often observe the rotation of water and ink rollers.
10. Ink: The operator needs to master the ink -matching operation process. Generally, the chromatography provided by ink manufacturers is generally selected.
11, drying paper: The paper drying machine should be installed in the printing workshop, so that the temperature and humidity of the environment can be basically consistent.
12. Make up ink color: Sometimes the printed products will be printed in some colors, and not supplementing will affect the quality of the print.It should be printed again to make up the lack of ink and supplement the ink.
13. Real on the ground: It is difficult to print a high -quality field on the printing machine. The usual method is usually print twice, but at this time, the field should be separate. If the field and graphic are connected together, it is not appropriate.
