Summary of common problems in the gluing process of flap disc making machine
1. Air in the glue leads to wire drawing
Q: First turn on the glue switch on the manual screen of the operation panel, then turn off the glue switch after the glue is released, quickly wipe the glue head clean, and there is still a fixed point of glue in the nozzle within 5s.
A: Remove the screws on the glue head and turn on the glue switch. When you see the glue coming out, turn off the glue switch and install the screws.
2. Glue head leaks
Q: Make sure that the glue switch is closed, and glue has been flowing out of the glue head. The thimble doesn't fit well with the top ring.
A: When hitting the manual interface, first open the glue switch to put glue, loosen the four screws on the side of the glue head, and remove the front part of the glue head.
-- First check the top ring, if the top ring has a gap then change the top ring, if the top ring groove is too deep also change the top ring;
-- If the top ring is ok, close the glue switch to expose the thimble and check whether the thimble is notched;
-- Change the thimble: there are four screws on the cylinder at the end of the rubber head. After loosening the screws, the cylinder can be pulled out, and the iron rod connected with the cylinder is the thimble;
Note: when disassembling the glue head, open the glue switch or close the air source, otherwise it is easy to pull the screw;
3. The cylinder current limit of the glue coating switch is inappropriate
There are two holes on the cylinder, when the tail air, head exhaust, the cylinder forward; When the head inlet, tail exhaust, the cylinder pull back; And when a hole air, another hole blocked, the cylinder is not action;
Part of the cylinder hole joint is adjustable, adjust the speed of exhaust, indirect regulation of the speed of the cylinder; Counterclockwise fast, clockwise slow;
In actual production, the glue switch needs to be opened quickly, so the regulating valve behind the glue switch cylinder should be completely opened;
Close the glue switch cylinder: because the action of the thimble is to push forward, the corresponding part of the glue in front of the thimble is extruded; If the front top thimble action is too fast, it will cause the glue to suddenly become large (uneven), so the front of the regulating valve should be appropriate to adjust; The speed of closing the glue switch will affect the stopping Angle;
4. Foreign bodies in the corner mouth
Q: The amount of glue suddenly becomes smaller. If it is a double nozzle, the amount of glue is large and the amount of glue is small.
A: Remove the rubber nozzle and clean up foreign matter;
5. Pressure should be stable, otherwise the glue quantity between the cutting pieces is different;
6. The environmental temperature difference is best and stable, affecting the pendulum;
7. Continuous production is interrupted and the time is more than 20S. Bake the nozzle before starting.
8. If you do not produce within 2 hours, please turn off the heating, heating the same glue for a long time is easy to lead to glue curing;
9. Add water in time, water has been evaporating, too little water is easy to damage the heating part;
