How to install the plastic barrel for the PUR hot melt glue machine?

2021/08/26

     Hello everyone, today we will explain the operation details of the fourth generation PUR hot melt glue machine to install the plastic bucket.


    First, turn on the power switch of the PUR hot melt glue machine. After setting the temperature of the pressure plate, wait for the PUR hot melt glue machine to warm up. When the pressure plate reaches the set temperature, the three-color light will turn on green, and then the glue can be carried out. The barrel is installed. Open the blowing rod on the pressure plate. Before preparing to press down, we first coat the sealing ring on the pressure plate with high-temperature butter. This may be easily missed by many customers. Why do we need to coat it with butter? It can reduce the friction between the sealing ring and the rubber barrel during the pressing down process of the pressure plate, and make the pressing down more smoothly.


    We press the up button on the cantilever operation box to raise the pressure plate to a height enough to put the rubber bucket underneath. Now put the rubber bucket on the right position. Now you can press the down button on the cantilever operation box. When entering the rubber bucket, you need to carefully observe whether the pressure plate is aligned with the mouth of the rubber bucket. If it is not aligned, stop and adjust the position of the rubber bucket in time. After the position is aligned, you need to tighten the fixing blocks around the rubber bucket.


    Here our fourth-generation PUR hot melt adhesive machine has 2 major advantages:

    1. The touch screens on the market are all fixed on the electric box. We have to press the button while observing whether the pressure plate is aligned with the mouth of the rubber barrel, which is not convenient; while the fourth-generation PUR hot melt glue machine uses It is a cantilever operation box, which can rotate 360 degrees. Our operator stands on the side of the rubber bucket and moves the cantilever operation box to the front to operate. We can observe the pressing down of the pressure plate while holding down the push button.


2. The PUR hot melt glue machine on the market does not have a cylinder double balance bar. Many friends report that the pressure plate will tilt during the pressing process, which will damage the rubber barrel more seriously; while the fourth generation PUR hot melt glue machine uses a double balance bar , It can ensure the vertical state of the pressure plate and the cylinder lifting rod when pressing, so that the rubber barrel will not be crushed, the pressing process will be smoother, and the amount of glue can be increased. Because once the pressure plate is tilted, it will become more and more difficult to press down after entering the glue bucket. The contact surface between the pressure plate and the hot melt adhesive is small, the melting speed is slow, and the glue is difficult to draw. These various reasons will lead to a small amount of glue.

After the pressure plate is aligned with the rubber bucket, continue to press the button. When the sealing ring is completely in the rubber bucket, you can press the automatic push button to let the pressure plate press down by itself. At this time, we need to pay attention to the blowing valve if there is hot melt glue flowing out, indicating that the air in the barrel has been exhausted, we can close the blowing rod.
