The numbering machine of the Rota Company’s computer ticket production equipment generally has a service life of 1.5 million times. Sometimes it is used improperly, the main parts are replaced, and it breaks after 300,000 hits. How to extend the service life of the header and reduce the cost of unit hiccups?
After exploration, it was found that the direct cause of damage to the number header was the electromagnetic driver that drove the number head to work. Open the top cover of the driver and use the socket wrench to remove the iron core with a buffer bar. At this time, you can see the coil cover under the bar, with two 20mm x 10mm x 5mm buffer sponges. If these two small sponges are completely different and they lose their cushioning effect, they will affect the life of the pier.
We did this: remove the sponge residue, replace the buffer bar with a washer with an outer diameter of about 3.5 cm, and put 3-4 layers of old rubber with an outer diameter close to the gasket on the iron core. In the drive, the number of the head is used to try again. If the number does not jump, it means that the stroke of the driver is not enough to hit the floor downwards. You can remove a piece of gasket or peel off one of the rubber mats until you reach the number of the head. The itinerary and pressure.
The improved driver can be played 4 million times with a new number of heads, up to a maximum of 5 million times, effectively reducing the related production costs.
