In recent years, my country’s printing and packaging industry has introduced many foreign second -hand equipment, and as many as hundreds of manufacturers using second -hand rubber printers. At present, the purchase of domestic personnel is mainly to buy from domestic operating units or import directly from abroad. According to incomplete statistics, except for sales units in the intermediate link, there are currently more than 3O manufacturers that directly renovate and operate second -hand platiards in the country. Most of the users who use the two mobile phones, but there are not satisfactory conditions. So how to avoid buying a two -phone mistake? The author summarizes the following points for the reference.
. Pay attention to the brand of the second phone. To buy a second -hand printing machine, we must first have a full understanding of the printing quality, equipment performance and stability produced by companies produced by companies in the world. This is the basic prerequisite. If the ink bar or the seal fails to wait for the new equipment during the use period of the new device is not long, such a printing failure is not allowed, such machines cannot be included in the selection range.
. Clarify the original country or region of the two mobile phones. This is one of the factors that determine the quality and price of the second phone. The machine produced by the same brand, model, and at the same time, because the user used in the use of the machine in terms of technical quality, maintenance level, and the work load of equipment will directly affect the quality of the second phone. Therefore different.
. Clarify the second phone you want to buy. It turned out to be a printed card or a thin paper, whether it is consistent with your role. Generally speaking, it turns out that it is printed with thin paper. You can use it to print thin paper, or it can be adjusted to print card paper (the speed should be reduced). If you have a long -term printed card paper, you can only use it to print the card paper, and you cannot print the thin paper. Otherwise, it is easy to produce the faults of other printing. The Roland 700 series is another matter.
. Understand the production year and total printing of the equipment, and do not discuss the price by “color”. The production year and total printing of the device are one of the factors of the quality of the two mobile phones under normal use. In the same type of equipment, the morning and evening of production can basically explain the advancedness and improvement of the equipment; the amount of total printing can show the size of its remaining use value.
. Understand the credibility and ability of the second -hand equipment unit. Units directly engaged in the operation of the second mobile phone have four types: the whole people, joint ventures, collectives, and private in the system. It can be divided into two categories in the technical level: the other is exquisite technical and perfect after -sales service. After its renovation, the two mobile phones have improved to varying degrees in the mechanical accuracy and printing quality. After many years of problems, and internal corporate standards, he provides comprehensive after -sales technical services to ensure the supply of next accessories; another type of technical force is lacking. Its so -called renovation is just reinstallation after washing. Only improve the appearance and technical services of the two mobile phones. Therefore, users can make a choice according to their technical capabilities, the quality status and price of the two mobile phones after comprehensive analysis.
6. Carefully examine the second phone to listen, watch, touch, and test. Listening, that is, through human hearing, listening to the two mobile phones in the state of air operation, clutching instantaneous, and co -pressure work. If there is an abnormal sound in a certain part, whether it is a periodic or non -periodic impact, it shows that the problems of the original two mobile phones are not solved during renovation, and the reason must be found to be solved, otherwise it will affect the normal use in the future. See, whether the appearance and parts of the person’s visual inspection equipment are broken and oil leakage. See whether the movements of various components such as water rollers, ink rollers, connecting ink and other movements are normal and effective. Wait for. Touch, that is, through the man’s feel, the dragging part of the roller is compared to the paper, whether there is a dental or artificial damage, the vibration of the machine, and when using the hand disk motor, etc. The measurement is to measure the comprehensive accuracy of the main roller assembly on the machine with the help of the test tool, such as the radial beating and axial movement of the three -place and right of the left, middle, and right. Measure the accuracy of duplicate printing and visual inspection of water bars and ink. Generally speaking, the purchase of two mobile phones in the printing industry is printed on the network cable version. Therefore, our testing requirements for the two mobile phones can be based on the national standards of my country’s rubber printing industry.
7. Pay attention to the integrity of the two mobile phone information and special tools. When purchasing the second phone, the supplier must require the supplier to provide random technical documents, such as using instructions (operating manuals) and atons. The former is the operator’s correct use of the machine reference, and the latter is an indispensable basis for buying each accessory. At the same time as the factory number and production year of the machine, the number of zero, ministry (group) parts can be accurately reported by the 册 在 在. Without a map, it is difficult for you to buy the reserve you need. Dedicated tools are essential for operation adjustment or daily maintenance.
