Offset Installation and Debugging Layout and Planning (2)

Before installing the machine, technicians, mechanics, electricians, and operators are required to install, commission, and inspect the equipment, and read the relevant information provided by the manufacturer carefully to understand the machine's weight, length, width, and height. Technical parameters, combined with the actual situation of the workshop, reasonable selection of installation location and consider the basic requirements of the printing process: easy production management, favorable operation, safe production, but also taking into account the stacking of finished products, semi-finished products, the operator's touring aisle, Machine maintenance space, fire exits, and the location of ventilation, lighting, and piping during normal printing.

After the concrete is watered, it needs a certain period of conservation. The time depends on the concrete label and the climate. The general time is 21 days to 30 days. After the foundation is completed, follow the interface and cut the groove to reduce the peripheral equipment and the concrete stretching to the ground. The impact of the floor, if possible, is better to press the item with the corresponding weight before the equipment is stored, and the effect will be better.

When casting the foundation, the trenches, embedded pipes, and oil drainage trenches of the cable should also be taken into consideration to avoid re-excavation or placing unnecessary open lines. If there are steam hammers, air compressors or other equipment that may affect the foundation near the workshop, then a shock-proof tank shall be added around the foundation. General shock tank width of about 100 mm, deep and the same foundation, with sawdust or white ash filled.

Preparation of five offset presses before installation

Before the offset press is installed, it is necessary to make the necessary preliminary preparation work, mainly in the following aspects, using the sheetfed offset press as an example:
1. Power supply: According to the power determined by the installation instructions. Multi-color offset printing machines such as the use of electric heating, UV (UV), IR (infrared) drying device, the required power consumption will be another design, the specific data should be based on the reference data provided by the instruction manual for power supply arrangements, and Meet the safety requirements of electrical appliances.

2. The location of the distribution box: It should be close to the entrance of the electrical control box of the offset printing machine. At the same time, it is also necessary to take into account safety, power supply and maintenance, and convenient maintenance. Set inside the box: fuse plug and fusion plug seat, air switch, lighting switch, low voltage lamp, power supply, single-phase power supply, etc. The value of the melting current of the fuse should be based on the power of the electrical device.

3, the work of the embedded pipe: This is a very important job, in general, the control of the electrical offset box is mostly placed in the transmission surface of the conveyor, pre-buried when doing the foundation, the choice of steel pipe should be based on the diameter The cross section and the number of roots determine.

4. Auxiliary equipment: The lighting needs sufficient brightness; ventilation should be arranged with appropriate rows and ventilation fans to keep the air in the workshop; the low-voltage lamps should generally be provided with sockets according to actual needs; the air conditioners arrange central air-conditioning or several units according to the area of ​​the plant. Air conditioning.

5. Pre-buried water supply pipes and drainage pipes: For multi-color offset printing presses, the general water supply outlet is on the transmission surface (outward), and the water consumption is not large. A steel pipe with a caliber of 18 mm or 12.5 mm can be used for water supply. However, to ensure constant water, once the water is cut off for a long time, the freezing system of the wetting system may malfunction, causing water shortage and rising water temperature, directly affecting product quality. The diameter of the drainage pipe shall not be less than 32 mm. When doing the foundation construction, the rationality of the supply and drainage pipes shall be taken into consideration.
