How to maintain the flexo machine? What are the methods and techniques?

Is there a need for maintenance of the flexo press? How to maintain it? What are the methods and techniques? The machine personnel must carry out a comprehensive inspection of the flexo press, repair, lubrication, debugging, wiping, and wait until the workshop is qualified before starting the next time. Production, at the end of each month, concentrate on the equipment to carry out a thorough maintenance.

The detailed maintenance methods and techniques of the flexo press are detailed below.

1, the tension part

The flexo press tension control system is an important device to ensure the printing registration. The long-term high-speed operation of the equipment will often result in lower registration accuracy, poor registration sensitivity and large fluctuations. During maintenance, the tension control sensor and other devices must be inspected and the magnetic powder in the magnetic powder brake must be replaced.

2, the transmission part

When the gearboxes of various color groups are subjected to printing pressure, long-term high-speed operation will cause gaps between the bearing and the inner bearing of the gearbox, resulting in lower concentricity and affecting registration accuracy. When it is severe, it will beat and affect the quality of the product. When repairing, replace the bearing in the gearbox according to the situation and adjust the gear clearance.

3, unwinding and winding part

The discharge and winding device should perform the high-speed operation of the uniform speed for a long time under the pressure of the paper roll. Over time, the gap of the transmission gear of the flexo printing machine will increase, which will affect the stability of the paper tension during the printing process. Gears, bearings, and gear support shafts should be replaced during repairs.

Weed Mat

The role of Weed Control Mat in agriculture is self-evident. Let's talk about its main functions,Inhibition of weed growth: Covering black grass cloth, weeds can not see light after germination, photosynthesis is inhibited, and the effect is very good.Increase the ground temperature: After covering the Weed Mat, the ground cloth can block the heat dissipation of the soil and increase the low temperature by 3~4 degrees Celsius.Keep the soil moist: After the ground covers the ground cloth, it can inhibit the evaporation of water, and adding polymer functional materials can maintain a certain soil moisture, which can reduce the number of watering and save labor costs. Improve soil compaction: After the ground covers the ground cloth, the Landscape Mat is well ventilated, the soil such as earthworms is increased, the soil micro-environment is improved, the soil is loosened, and there is no knotting phenomenon.Our factory can customize the weeding cloth that customers want according to their needs. There are multiple choices in size and color. The price here is not only affordable, but also quality assurance.
