Dongguan Glue filling machine The problem may lie in: the quality of the filling valve is not up to standard, the sealing parts are worn and corroded, the glue is too thin, the air pressure is too high Glue filling machine Needle diameter is too small and other factors, today's Yinghe Xiaobian to summarize and analyze the solutions.
1、 Low quality filling valve, air leakage, processing accuracy is not high, valve can not be closed, will cause glue dripping.
2、 If the rubber valve is used for a long time, or the glue itself is corrosive, the seal will be damaged. In this way, there will be a sealing gap when the rubber valve is closed. The effect of suction will be greatly reduced, and the glue will also drip. Therefore, when the rubber valve is used for a long time, there will be glue dripping. First, change the seal and try it!
3、 The glue filler particles are too large and the proportion is too large, which causes the seal ring to wear. Replace the glue with better quality, and the problem is solved.
4、 If the air pressure is too small, it will also cause glue dripping. If the air pressure is too small, the cylinder will be weak up and down, which will cause insufficient suction force. It will also drip glue. Turn the air pressure up a bit
5、 This kind of situation often occurs after the rubber valve is closed. 95% of the cases are due to the small diameter of the needle used.
If the needle is too small, it will affect the flow of liquid and cause back pressure. As a result, the phenomenon of drip will be formed soon after the rubber valve is closed. If the needle is too small, it will affect the exhaust bubble action when the rubber valve starts to use. As long as the larger needle is replaced, this problem can be solved. The conical oblique needle produces the least back pressure and the most smooth liquid flow. The air in the liquid will leak after the rubber valve is closed. It is better to remove the air in the liquid in advance, or use the glue which is not easy to contain bubbles, or centrifuge the glue before use.
To sum up, when you meet Dongguan glue filling machine When the glue is dripping or cannot be collected, take apart the rubber valve, check the sealing ring first to see if there is corrosion, and then test it one by one. I believe that you will find out the root cause of the glue dripping, and then take corresponding measures, and your glue dropping problem will be solved easily!
