With the advancement of science and technology, it has driven the rapid development of related industries, and the application of this dispenser is also true. It appears in many areas of the production process. So what are the common problems of dispensing machine?

1. Dripping of glue valve

There are two main reasons for valve dripping, most of which occur after the valve is closed. One is because the used needle is used for too long or the operation of the needle head bump, resulting in needle wear or deformation. Too small or too large needles will also affect the flow of glue, and back pressure will be formed in the glue valve, causing the glue to drip out after the glue valve is closed. Second, there are bubbles in the rubber valve, which can not meet the air pressure requirements of the valve body required for dispensing, causing the glue to slowly leak out. In order to prevent the leakage of glue caused by air problems, the glue is generally degummed first, and the end air and the previous waste glue are discharged when the glue valve is pumped.

2, the flow rate is too slow

Check whether the needle is stuck and the push rod cannot be pushed down. If not, check whether the parameter has changed. You can appropriately increase the glue pumping speed of the glue valve and increase the flow rate of the glue.

3. The size of the glue is inconsistent

The main reason for the inconsistent glue out of the glue out valve is that the pressure of the glue out valve is unstable or air is pumped in. The inlet pressure regulator should be set to 10-20 psi lower than the factory pressure, and the low pressure part of the pressure between the pressure gauges should be avoided. Glue valve control pressure appropriate to increase the viscosity of glue, generally between 50-150. After checking the glue time. Too short words out of the glue too fast, easy to stick. If the time is too long, the glue is stable, the time is too long, and the production efficiency is low, so the time depends on the amount of glue.

How to maintain the dispensing machine?

1. First of all, we should give all automatic dispensing machines a good production environment and maintain a dust-free workshop. The workers brought shoe covers into the workshop to keep them out of dust. Deal with the site in time after each dispensing and keep the parts clean. This can improve the service life of the automatic dispensing machine.

2. If our automatic dispensing machine is not used for a long time, then we have to unplug the power supply, which can avoid many accidents, save electricity, and protect the dispensing machine.

When using an automatic dispensing machine, it is often necessary to glue different products. When changing the fluid glue, clean the syringe pipe to avoid blockage and affect the glue.

4. The automatic dispensing machine will have abnormal air intake and water vapor. To check the air pressure source is not abnormal, timely eliminate water vapor, so that the machine is not easy to malfunction, the use of high efficiency. Nature can hold on a little longer.

What are the application principles of dispensing machine?

1, curing factors: for the curing of glue, manufacturers will generally give the temperature curve. Generally, it can be cured at room temperature. In actual operation, it should be cured at a higher temperature as much as possible, so that the glue has sufficient strength and hardness after curing.

2. The bubbles generated by the dispensing machine during the dispensing process will affect the product quality, so there must be no bubbles before the glue is put in. If there are bubbles, the products produced by the dispensing machine will have many defective products. When using, the air in the glue should be discharged to prevent the dispenser from empty dispensing.

3. The vacuum suction valve must be installed on the dispenser. The vacuum suction function is mainly to prevent the glue from dripping when the dispenser is not working. After installing this kit, the vacuum suction valve can be adjusted appropriately to further control dripping and wire drawing.
