Glue quality is an important factor affecting the jet type automatic dispensing machine coating dispensing quality, high viscosity glue is mainly applied to strengthen the bonding strength between products, if necessary products have a high strength adhesive effect, should be strengthened to strengthen the cohesive glue bonding strength between products, it is worth noting that to avoid the existence of bubbles in the glue the bubble may be the glue, glue quality problem may also be caused by uneven mixing, glue fully and evenly stirring to maximize the removal of gas bubbles in the glue. An application of dispenser dispensing glue coated link valve, the operator of the large volume of the plastic dispenser control effect needs to be applied to jet dispensing valve, dispensing valve can real-time control the quantity of cement to meet the requirements of the product coated glue, glue the quantitative control of the value of the products has been further improved, so regular maintenance check dispensing valve is a necessary work. Badges were coated adhesive is in order to enhance the appearance of the surface effect, in order to enhance the quality and efficiency of dispensing badge coating, the coating can be carried out through the dispensing large jet dispensing machine, large jet dispensing machine badge coating effect more fully evenly, avoid contact dispensing and scratching the surface of metal badge.
