First, we need to understand the adjustment function of each part of the glue machine and glue gun
Explain Figure 123
In the above figure 1, the whole glue gun can be divided into three adjustment parts. 1 The circled screw is the glue gun shutoff valve, which controls the size of the glue gun outlet (clockwise tightening is small, counterclockwise loosening is large). 2 Glue scraping width adjustment, which controls the size of the glue scraping outlet. 3 Glue scraping outlet
In the above figure 2, there are three positions at the back of the glue machine where the glue hose is connected, respectively. 1 is the glue machine shut-off valve, which controls the size of the glue outlet of the glue machine. (Tighten clockwise for large, loosen counterclockwise for small) 2 is the glue outlet, which should be blocked when no hose is connected. 3 is the glue outlet, connect the hose
Figure 3 is the front control panel of the machine
1 is the frequency of glue pumping. Control the amount of glue pumping,
respectively control the temperature of the glue gun or the hose
(II) Glue adjustment
Under normal circumstances, the distance between the glue scraping port Figure 3 and the surface of the material to be glued is about 1 mm. The adjustment position varies according to the installed machine model. The width of the glue scraping can be adjusted through Figure 1 2, generally from narrow to wide. The width adjustment part has a rough scale mark, such as a 30 width side strip, which can be adjusted from 25. The appropriate width can be adjusted through the glue scraping test.
If you encounter the following situations when adjusting glue, you can deal with it in the following ways.
1. Uneven glue discharge!
Method 1. Appropriately adjust the inverter at the place marked 1 in Figure 3 clockwise to increase the amount of glue. Or adjust the glue machine shutoff valve at the position marked 1 in Figure 2 and turn it clockwise to increase the amount of glue pumped.
2. More glue at the head and less at the tail.
This can be controlled by adjusting the glue gun shutoff valve at position 1 in Figure 1. Generally, turn it clockwise to the tightest. Then loosen it counterclockwise for half a turn and test the glue output. According to the test results, if the glue output is still more at the head and less at the tail, tighten it clockwise a little. Otherwise, loosen it counterclockwise. Adjust until the glue output is uniform.
If there is less glue after adjusting the glue gun, you can increase the glue amount by adjusting the frequency of the glue machine at position 1 in Figure 3 (but the frequency should be controlled within 35), or adjust position 1 in Figure 2 and turn it clockwise a little to increase the glue amount.
3.Glue scraping thickness. Control by adjusting the distance between the scraper and the material coating surface. If the glue is thin, you can adjust the distance closer and reduce the glue amount. If you need a thicker glue, adjust the distance a little further and increase the glue amount.
4.Notes: Test the glue output and adjust the glue amount according to the observation. The glue amount should not be adjusted too much. Just apply it evenly on the edge strip surface when the glue is output. When applying glue, there should be no excess glue accumulated behind the glue gun. It will easily drag the glue or get stuck on the edge strip. This can be solved by increasing the distance of the scraper gun to apply glue on the edge strip surface, or by reducing the amount of glue pumped.
