Rubber tube can cause bubbles in glue, the way of replacing
Whether the automatic dispensing machine can apply glue is directly related to the effect of glue control. Only when there are no bubbles in the dispensing syringe can the dispensing process be carried out evenly. Bubbles can cause problems such as wire drawing, dripping, reducing glue volume and inconsistent glue dots. Bubbles usually occur when the rubber tube is replaced and filled with glue. When water appears,
Ways to Solve Bubbles in Needle Barrel
First of all, we need to know where to enter the bubbles, which is generally caused by better hose problems, so when replacing the hose, pay attention not to introduce air into the inside of the dispensing syringe. If there is air residue in the hose, and you are sure that air does not enter the dispensing pump through the hose, it can be discharged. Whether the rubber hose is damaged or not and how to eliminate bubbles are determined.
Please replace the machine hose by following steps:
First shut down the pressure and power supply of the automatic glue coating machine, unscrew the screw of the dispensing valve, then re-unload the cooling sleeve from the rubber pipe, unload the pressure head, determine the material pipe interface to pay back to the glue dispensing valve, and remove the rubber pipe. If the glue shortage occurs in the elbow of the material is found, the old glue needs to be filled to solve the glue vacancy and gas. Bubble problem, then check whether there are bubbles in the locking adapter. If there are bubbles, a material joint needs to be replaced. Another way is to replace the rubber hose, which can ensure the smooth output of the rubber volume. This is the effect of the rubber hose replacement.
