There are many things we need to pay attention to in our normal use of the two-component dispenser. If we don't pay attention to these places, it is likely that our two-component dispenser will present various problems. This will not only affect your production power, reduce your revenue, but also significantly reduce the life of the equipment
Today's small edition on the introduction of two-component sizing machine in the ordinary production operation should pay attention to which aspects. You can strictly follow the contents of the editor to avoid unnecessary problems and problems.
1. The air release valve on the pressure plate shall be kept clear, dredged and cleaned regularly.
2. Do not cut off the air source during normal operation. If any, stop the operation.
3. If the pause time is more than 15 minutes in the process of two-component gluing machine gluing operation, it is necessary to use "shot gun". This machine has an alarm function. There will be a buzzer alarm if there is no glue flushing.
4. Check the air source regularly. First, make sure to use dry and clean compressed air, regularly discharge the accumulated water in the separate filter, and check whether the oil in the oil atomizer is sufficient.
5. In case of air, component B of silicone rubber will crust, which will affect the normal operation of the pump and the dredging of the pipeline. Therefore, all channels of component B rubber shall be closed after pressure relief during shutdown, so that component B shall not contact the air.
6. If there is air in the B rubber barrel, the air will not be discharged, and the B pump will move rapidly to and fro, and cannot supply glue to the high pressure pump normally, which will affect the whole system. Therefore, the air must be discharged. The method is: lift the pressure plate and press it in again and release the air.
7. The pressure of the hydraulic station system cannot be adjusted too high. According to the actual situation such as the indoor environment temperature, adjust the pressure to the satisfaction that the glue nozzle is normal and the glue is evenly applied. When opening the hydraulic station, the glue gun must be opened, otherwise the pressure of component B pipeline will rise very high, forming a safety accident.
8. The continuous operation of a glue lift pump for more than 1 minute does not stop the supply of glue, which means there is air in the pipeline. At this moment, an alarm will be given. It is necessary to open the upper pipe joint of the pump and then the a glue lift pump until the delivery of glue is stopped. Stop and connect the joint. The glue gun will show an air beep explosion, and the air will be discharged completely.
9. Because the mixer will not be completely clean every time, a small amount of mixed rubber will accumulate every time, more and more, which will block the mixer channel. After a period of time, the rubber output and mixing effect will be affected, so it is necessary to clean the mixer regularly (polysulfide rubber for five days, silicone rubber for two days). Remove the mixing bar in the mixer, and replace it with a new one if it is damaged. If the rubber mixing rod cannot be removed, it can be burnt out by fire. Pay attention not to damage the thread of parts.
2、 Maintenance of two-component gluing machine
Clean the surface of the spray gun and the nozzle of the two-component gluing machine to ensure that the nozzle is unblocked;
Clean or replace the filter screen of glue machine and spray gun;
Check whether the spray gun has leakage. If there is leakage, please adjust, repair and replace the spray gun, nozzle, nozzle and other parts that need to be replaced.
Check whether there is a carbonized layer on the inner wall of the rubber cylinder. If there is a carbonized layer, please clean the rubber cylinder with the special cleaning solution r of nuoxin.
Heat the glue machine to the operating temperature and empty the hot-melt glue in the glue box. Check whether there are impurities in the rubber cylinder. If there are impurities, clean the rubber cylinder with a clean cloth.
Check whether all junction boxes and terminals of the two-component dispenser are firm;
Check whether all power plug wires are damaged and other insulation parts are secure;
Clean and check the inside of the rubber machine electrical box;
Check whether all power pins of the two-component dispenser are firmly connected.
