UV printer has the characteristics of no plate making, namely dry, not only can print ordinary effect, but also can print 3D and relief effect, but also a wide range of printing materials: packaging boxes, acrylic, KT board, U disk, glass, tile, wood, metal, etc.,
After the advent of the edge quickly occupy the market, UV printer has become a trend. UV printer in the use of the process is very strict, once improper operation will damage the life of the equipment, the following dangerous operations.
1. Do not plug and remove the line
When checking the machine board and nozzle, there is no electric discharge treatment. The non-standard use will lead to the contact of the line and the board, and more seriously, the print head will be damaged. Therefore, when checking the machine, it is necessary to turn off the power and unplug the power cable before discharging
Tighten and align with the data wire hole, no deviation or oblique needle. In the case of not turning off the power and cutting off the total power supply, install and disassemble the UV flatbed printer circuit at will. This behavior will damage the service life of each system and harm the sprinkler head.
2. Adjust the nozzle by brute force
Use external force to adjust the nozzle position. Do not use brute force when replacing or fine-tuning the sprinkler head. Please treat the sprinkler head with care according to the specifications.
3. Ignore the work ground
UV flatbed printer printing is greatly affected by static electricity, should often check the ground device connection, regularly sprinkle a little salt water around the ground. The working environment should be ventilated, the dry and humidity should be controlled within the scope specified in the machine manual, and the machine should be cleaned and maintained regularly
The replacement of vulnerable parts makes the machine run more stable and long.
4. Disassemble the head at will
Print head is a very precise and fragile part. Do not replace the plastic parts of print head or clean the circuit board inside the sprinkler head at will. If the head cover needs to be replaced, contact the machine manufacturer to give professional guidance, and non-professionals do not remove it.
5. The power supply is not turned off for cleaning
Cleaning without care to protect circuit boards and other internal systems. Please turn off the power when cleaning, and be careful not to let the water touch the circuit board and other internal systems.
6. Use inferior cleaning liquid
Clean the nozzle with inferior cleaning liquid. Sprinkler heads are easy to be polluted and worn, so please use the products specified by the manufacturer and the quality inspection products to clean the sprinkler heads.
7. High pressure cleaning nozzle
When cleaning the nozzle, if the nozzle is slightly blocked, it is recommended to use a vacuum cleaner to wash out the dust and then clean it carefully. Do not use this way.
8. Soak and clean the nozzle
Although it is more effective to clear stains by soaking the whole nozzle in the cleaning solution for a long time, the cleaning solution is corrosive, and if the time exceeds 48 hours, it will affect the print head hole itself. Therefore, generally only take an appropriate amount of the nozzle into the cleaning can be.
9. Sound wave cleaning print head
Use ultrasonic cleaning machine for a long time to clean the print head. In fact, if you pay attention to the print head maintenance, there is no need for ultrasonic cleaning. Ultrasonic waves can have a bad effect on the sprinkler head. But if the blockage is serious enough to require ultrasonic cleaning,
The maximum cleaning time is 3 minutes. If it is not cleaned once, please wait for the print head to naturally cool down to the normal state before the second cleaning.
10. Use bad ink
Add different batches of ink at will, or use inferior ink, cleaning fluid. Two different configurations of ink mixed will change the color and quality of the ink, the quality of the ink will affect the printing effect and block the nozzle, damage the nozzle life.
11. Can’t be fixed maintenance and maintenance of machine and precision parts
How long a machine lasts has a lot to do with its users and operators. As we all know, we will regularly maintain and replace vulnerable parts of a car. Only in this way can we use it for a long time and have a good safety and stability. So the same goes for printers, as users
We have the obligation to maintain and replace vulnerable parts regularly, so as to keep the printer in a safe and stable working state. Can not blindly only to use and do not know the maintenance and maintenance, over time, the aging of the components and lines, pipeline problems will affect the use and printing
The life of the machine, more serious cases will lead to continuous problems.
The above is several dangerous operations in the use of UV flatbed printer. The correct use and maintenance of UV flatbed printer can not only ensure the normal efficient production operation of the machine, but also extend the service life of UV printer, and can greatly reduce expenses and costs.
Some incorrect operations not only greatly reduce the service life of the printer but also seriously affect the production efficiency.
