Canadian strip sheet 3/4 automatic uv screen printing machine

plywood

Applications :

Mainly for signs factory, paper box packaging silk screen processing plants, Electronics, toys, gifts, clothing, stationery, cosmetics, washing products, chemicals, food, health product, pharmaceutical and packaging etc.

Advantages:

1,  servo motor drive, printing runs smoothly, High precision printing for big size printing;

2,  UV light source , Drying uv ink on sheet is very fast than heat dry ink;

3,  Energy saving and environmental protection, Suitable for clean room(dust-free workshop).

FAQ

Q1:
How difficult would it be to modify our printer with a squeegee on both sides, and change the program to print in both directions ?
R-L, lift... 1 print... L-R, lift... 1 print
1st print - Squeegee pressure R-L, then raise. New substrate... 2nd print - Squeegee pressure L-R, then raise. (each direction is 1 print with new sheet).
The reason is, we are using a stencil with holes. Pushing the ink L-R with the aluminum blade causes the ink to leak through the holes. It would be better if we printed, once in one direction, then once in the other direction.
what is required ? A squeegee on both sides ? If you can show me the parts, I will understand. I am mechanical engineer and design machines as well.
I also work with PLCs and can make modifications
A1:
Solution 1
cancel flood bar ,change to 2 squeegee
Solution 2
Directly cancel the oil return scraper , only use 1 squeegee scraper to move back and forth
The risk lies in the action interference. Pay special attention to dragging the uv machine away first to ensure a safe distance from the screen printing machine to prevent fights and ensure that the robotic arm does not touch the screen printing machine during the debugging process.
Ensure that the movements are coordinated and meet the requirements, and then the two parts are sent to the correct position
The robot PLC program should not need to be changed

Q2:
Can it be done with just a program change ?  This would be ideal. I guess one squeegee would print in both directions.
A2:
The U disk file can only change the touch screen display, and the PLC program file becomes the desired action, which needs to be continuously debugged. The machine is not in China, it is difficult to achieve. We suggest that you will work on the current state, single squeegee printing, the left and right tilt angles are inconsistent, and you need to adjust the descending height of the head during the return printing process
Looking forward to your video feedback on normal production status，thank u
Q3:
How much time will the reprogramming take ? Can we upload the new program ? We have very little time to make this work.
A3:
Express back and forth plus programming time, you budget 40 days
Disassemble the touch screen and PLC and send them to us for modification.
Pay special attention to the risks, it is easy to disassemble and difficult to put back, and it is very dangerous to connect a wrong wire, remember to record the whole process for backup.
 Remember to videotape the whole process of disassembly and assembly for future reference.
Q4:
I need it working in a week. Do we have access to the program ? I have a good programmer if it is a change in the logic sequence.
A4:
First ask him if your programmer  can understand the existing program, if he can understand the original command code, keep a backup, and then try to change the code
If your programmers can't understand the factory code, try not to change it.
Because DHL express usually 7~15days
Q5:
Thankyou... we are working with the program, but it will be difficult to do ourselves. We have no trouble loading a new program on the PLC. Can you generate an updated program for the 2 direction printing ? We can gladly pay for the change.
This work is urgent and we need the change asap - please let me know if there is any option to expedite the work.
A5:
 This program change cannot be implemented remotely, it must be debugged on site, and it is too expensive for engineers to go to Canada
Q6:
Ok, I thought you wanted the PLC shipped back for programming (which seems like just loading the program), I don't know how that helps debug.
I must have misunderstood.
A6:
Thank you for providing us with a design idea,
The next time I encounter long strip printing, I will advise customers to print bidirectionally to improve efficiency.
You have contributed to the industrial development of mankind, and you can also apply for a patent.
Q7:
Getting close. We have the full size stencil now. The squeegee travel is not parallel to the table. 10mm higher at one end. Is there adjustment for this ?
A7:
First, you can adjust the control handle of the screen frame to reach a distance of 5~8mm from the platform.
Adjustable workbench
Disassemble the cover plate, there are screw adjustments inside
If it is adjusted to the limit, put something in to level the workbench
There should not be so much difference. We adjusted the workbench level when assembling.
Q8:
Strange... We have a new PLC program ready to download to the PLC, but are getting an "unlock error"... The 201129 pass doesn't seem to work. Any ideas? Is there a trick to connecting to the PLC ?
A8:
PLC program not free, you bought? and get key?
The new PLC has a password, you have to ask the PLC program supplier
