二手双组份打胶机还是性价比较高的设备，在选择二手双组份打胶机时也会面临很多的风险以及陷阱，这时候就需要在选购二手双组份打胶机的时候更加细心和仔细，防止上当受骗。

Second hand two-component glue applicator is still a cost-effective device. When choosing second-hand two-component glue applicator, you will also face many risks and traps. At this time, you need to be more careful when choosing second-hand two-component glue applicator to prevent being cheated.

双组份打胶机是一个结构比较复杂的玻璃机械，从大体上分为供胶机和涂胶机两个部分，但是中间有一些复杂电气、电路连接。所以在选购二手双组份打胶机时要把这几个部分检查一下，防止买回来的时候出现故障。可是时间不允许我们一处处的检查，所以有几个要点去检查。

The two-component gluing machine is a glass machine with complex structure, which is generally divided into two parts: glue feeder and glue applicator, but there are some complex electrical and circuit connections in the middle. Therefore, when purchasing a second-hand two-component glue applicator, you should check these parts to prevent failure when you buy it back. However, time does not allow us to check everywhere, so there are several points to check.

检查供胶机上面供胶管、混交棒是否完好

Check whether the rubber supply pipe and mixing rod on the rubber feeder are in good condition

众所周知，在供胶机上重要的就是供胶管了，它用于给打胶机供胶。但是，有一个常见的问题老是躲避不了的，胶体是比较粘稠的，由于胶体的特殊性，很容易堵塞供胶管。如果之前的主人在使用过程中对打胶机并没有进行清理和保养，那么双组份打胶机很有可能已经堵塞，严重的可能已经损坏了。这部分如果一旦出现问题，就会导致设备的出胶不正常甚不出胶。所以供胶管要要点检查一下。

As we all know, the important thing in the glue feeder is the glue supply pipe, which is used to supply glue to the glue dispenser. However, there is a common problem that cannot be avoided. The colloid is relatively viscous. Due to the particularity of the colloid, it is easy to block the rubber supply pipe. If the previous owner did not clean and maintain the glue applicator during use, the two-component glue applicator may have been blocked or seriously damaged. Once there is a problem in this part, it will lead to abnormal glue output or even no glue output of the equipment. Therefore, the supply hose should be checked.

需要检查的地方在打胶机上面。

The place to be checked is on the glue applicator.

我们知道把要胶供给打胶机，但是之后要怎么去打胶呢？在打胶机的工作原理是靠气压把胶挤压出来无缺的涂在打胶机上。为什么要第二个去检查这个呢？因为打胶全靠气压，如果气压不够，你想想这胶还能不能无缺的打出来呢。所以我们要检查一下双组份打胶机的压力系统是否能正常的调压。

We know that we need glue to supply the glue dispenser, but how to apply glue later? The working principle of the glue applicator is to squeeze the glue out by air pressure and apply it on the glue applicator without defect. Why should I be the second one to check this? Because the glue is made by air pressure. If the air pressure is not enough, think about whether the glue can be made without defects. So we need to check whether the pressure system of the two-component glue applicator can adjust the pressure normally.
