Be careful not to introduce air into the colloid channel when replacing the hose with a two-component glue filling machine. If there is air residue in the hose and you decide that the air does not enter the dispensing pump through the hose, please replace the hose according to the following process:

关闭点胶机。打开门，从胶管上卸下冷却套，假如有冷却套。卸下气压头。撤消胶管。请承认90°的弯管配件还附着在点胶阀上，假如有弯管配件。胶管卸下后，点胶阀断定转接头底部会发作一小段空腔。请运用旧胶管中的胶体填充这段空腔，并检查断定转接头中是否存在气泡。

Turn off the dispenser. Open the door and remove the cooling sleeve from the rubber hose. If there is a cooling sleeve. Remove the pneumatic head. Undo the hose. Please acknowledge that 90 ° elbow fittings are also attached to the dispensing valve, if there are elbow fittings. After the hose is removed, the dispensing valve determines that there will be a small cavity at the bottom of the adapter. Please fill the cavity with the colloid in the old hose and check whether there are bubbles in the adapter.

假如有气泡，请运用新的胶管填充这段空腔，并检查新的胶管是否存在气泡。假如有气泡存在的话，请运用另一个胶管。卸下新胶管的盖帽。坚持胶管结尾向下，让胶体彻底地填满胶管底部，联接胶管和点胶阀断定转接头。假如胶体溢出到配件外，请擦拭洁净。重新安装气压头。重新安装胶管冷却套，假如有冷却套。关闭点胶机门。重新启动设备。

If there are bubbles, please fill the cavity with a new hose and check whether there are bubbles in the new hose. If there are bubbles, please use another hose. Remove the cap from the new hose. Keep the end of the hose down, let the colloid completely fill the bottom of the hose, and connect the hose and the adapter of the dispensing valve. If the colloid spills out of the accessories, please wipe it clean. Reinstall the pneumatic head. Reinstall the hose cooling sleeve, if any. Close the dispenser door. Restart the device.

全自动点胶机排胶要留有成分的时刻，使新胶管中的胶体顺利流出点胶头，承认点胶阀的压力和速度依照志向情况设定。然后测定胶体流速，直接连两次丈量成果的过失在正负2%规划以内。

The dispensing time of the full-automatic dispensing machine shall be reserved to make the colloid in the new hose flow out of the dispensing head smoothly. It is recognized that the pressure and speed of the dispensing valve are set according to the ambition. Then measure the colloid flow rate until the error of two consecutive measurement results is within plus or minus 2%.

另外还需要留心一点，假如存在下述情况，建议不要运用简易的胶管替换方法：点胶机在运转过程中，胶管中胶材现已用完。该情况下点胶阀中很可能有空气存在。自动灌胶机胶管中的胶材现已超过了运用期限。呈现以上任何情况，你有必要彻底清洁并单调点胶阀或点胶泵，并遵照装备过程。

In addition, you need to pay attention. If there are the following situations, it is recommended not to use a simple hose replacement method: the rubber material in the hose has been used up during the operation of the dispensing machine. In this case, there is likely to be air in the dispensing valve. The rubber material in the rubber hose of automatic glue filling machine has exceeded the service life. In any of the above situations, you need to thoroughly clean and clean the dispensing valve or dispensing pump, and follow the equipment process.
