The code-injector does not work for a long time, how to solve the problem of nozzle blockage?

　　Pharmaceutical Network Technical Article: Code-spraying machine in the food, pharmaceutical industry is a common identification equipment Among them, ink spray machine high efficiency, wide range of applications, coding effect specifications, has been widely used in various industries
In recent years, with the continuous development of science and technology, as well as the continuous progress of coding technology, laser coding machine as a new high-tech coding equipment, can be used to replace a part of the ink spray machine However, because the laser material requirements are more stringent, there are some materials so far can not completely replace the ink coder, coupled with the high cost of laser code rafter, according to different types, different wavelengths, different energy requirements, the price gap is very large Therefore, the current market ink spray machine still has a pivotal position
At a special time, most companies have issued notices of delays in returning to work in preparation for pre-work The author learned that the ink spray machine in a long period of production, easy to cause the problem of nozzle blockage, to the spray code work to bring trouble, affecting normal production Therefore, how to avoid and solve this problem becomes a problem that users want to know
It is understood that the long shutdown of the code-injector may cause the ink supply lines and nozzles have residual ink drying up, making the ink in the ink supply line or nozzle door to form a blockage or completely blocked
How to avoid it in advance? Industry engineers suggest that users need to develop good standard shutdown habits (using stop keys) in peacetime, regularly turn on the machine
In addition, if a long shutdown does not require a shutdown, be sure to follow the normal shutdown procedures It is reported that the coder in the normal switch machine in the process of the machine ink lines will be a comprehensive cleaning, so that the ink and nozzle in the no residual ink dried up, so that even if the coder long-term shutdown will not cause the phenomenon of nozzle blockage
There are also many users will ask, not to achieve these preparations, sprinklers have been blocked situation how to do? Based on their years of experience, industry engineers have summed up two common phenomena and corresponding solutions for the industry's reference only
First, there is a ink line is not allowed to be straight, in this case the ink line is opened after the ink line is shot out of the nozzle but not into the recovery tank The nozzle should be cleaned immediately
Second, no ink line is not allowed to be straight, open the code-injector found no ink line spewing out, machine inkjet is not allowed to directly explain the nozzle completely blocked Remove the nozzle immediately, use the nozzle or use ultrasonic waves for cleaning, and use the syringe to test whether the nozzle has been unblocked
The industry also reminds that users need to take extra care of the nozzle in the process of daily use of the code-spraying machine Whether it is nozzle maintenance, removal, preservation, cleaning or immersion need to be careful, never let the nozzle membrane touch any hard objects At the same time, the surface part of the nozzle can not be rubbed with any object, otherwise it is easy to damage the nozzle film
In addition, if the user soaks the nozzle for a long time and injects the cleaning fluid into the nozzle for a long time, the nozzle film and the cleaning fluid will react, the nozzle film will easily fall off, affecting the nozzle to be used again Once the nozzle membrane is damaged or shedding, the spray equipment can not be used, can only replace the entire spray dock, so in the use of spray code, the maintenance and maintenance of the nozzle to cause attention, maintenance and maintenance of a good nozzle, in order to effectively extend the life of the spray machine.
