點膠機膠閥的運用要注意哪些問題？
1、點膠機上膠閥滴漏這一場景在以后經(jīng)常發(fā)生在膠閥關閉時。95%的這些圖像是由于使用的針頭太小造成的。如果針頭太小，就會影響液體的運動，形成反壓力。這一結果將導致橡膠閥關閉后不久出現(xiàn)滴漏現(xiàn)象。如果針筒過小，也會影響橡膠閥開始使用時排氣氣泡的作用。錐形斜針的背壓小，流體運動平穩(wěn)。膠水閥關閉后，內部液體空氣會滴漏。深圳點膠機生產(chǎn)廠家提倡，好提前清理內部的液體空氣，或者使用不含氣泡的膠水，或者將膠水離心后使用。
1. The leakage of the glue valve on the dispenser often happens when the glue valve closes in the future. Ninety-five percent of these images were caused by the use of too small needles. If the needle is too small, it will affect the movement of the liquid, forming back pressure. This result will lead to leakage shortly after the rubber valve closes. If the syringe is too small, it will also affect the role of exhaust bubbles when rubber valves start to use. The conical oblique needle has the smallest back pressure and the smoothest fluid movement. When the glue valve closes, the internal liquid air will drip. Shenzhen dispensing machine manufacturers advocate that it is best to clean up the liquid air in advance, or use glue without bubbles, or centrifuge the glue after use.
2、分配器的尺寸不一致時膠料不一致，主要是由于儲油缸的流體壓力或氣壓不穩(wěn)定。進氣壓力調節(jié)器應該設置在比工廠小壓力低10到15psi的地方。壓力缸內使用的壓力應在調節(jié)閥壓力中心以上。壓力應防止用于壓力表的低壓部分。橡膠閥門的工作壓力少為60psi，以保證膠水的穩(wěn)定性。后檢查上膠時間。如果小于15/1000秒，分配器的上膠時間會更穩(wěn)定。
2. When the size of distributor is different, the rubber material is different, mainly because of the unstable fluid pressure or air pressure of the oil storage cylinder. The intake pressure regulator should be set 10 to 15 psi below the minimum pressure of the plant. The pressure used in the pressure cylinder should be above the pressure center of the regulating valve. Pressure shall be prevented from low pressure parts used for pressure gauges. The working pressure of the rubber valve is at least 60psi to ensure the stability of the glue. Finally, check the gluing time. If less than 15/1000 seconds, the gluing time of the distributor will be more stable.
流量太慢了。如果流速過慢，管道應由1/4“改為3/8”。管道越短越好。
The traffic is too slow. If the flow rate is too slow, the pipeline should be changed from 1/4 to 3/8. The shorter the pipe, the better.
4、點膠機液泡過大，液壓力過大，如果再加上閥門開度過短，可能是空氣進入液中，處理方法是降低液壓力，并采用錐形斜針。
4. The dispenser has too large bubbles and too large hydraulic pressure. If the opening of the valve is too short, it may be that air enters the liquid. The treatment method is to reduce the hydraulic pressure and adopt a conical oblique needle.
5、即時膠(快干膠)橡膠閥‘聯(lián)合’和管道塊看到主要是因為過多的水分或重復使用強力膠,應保證新鮮即時膠水的使用,管道不徹底清潔的丙酮丙酮含有水分,應該得出的結論是,使用空氣干燥和廠內空氣壓力之間的橡膠閥系統(tǒng)和添加過濾器。(如果上述方法仍然失敗，則應施用氮氣。)
5. Instant glue (quick-drying glue) rubber valves and pipeline blocks are mainly due to excessive moisture or re-use of strong glue. Fresh instant glue should be guaranteed. Acetone and acetone which is not thoroughly cleaned in the pipeline contain moisture. It should be concluded that the rubber valve system between air drying and air pressure in the factory and the addition of filters should be used. If the above method still fails, nitrogen should be applied. )
6、UV膠(UV固化膠)確定使用黑線。不要直接添加UV膠老UV膠壓力缸,先把原來的UV膠水,然后把UV膠水到空壓力缸,增壓缸的UV膠通常通過一段時間后,泡沫和橡膠是不穩(wěn)定的。
6. UV adhesive (UV curing adhesive) determines the use of black line. Do not directly add UV glue to the old UV pressure cylinder, first put the original UV glue, then UV glue to the air pressure cylinder, and the UV glue of the pressurized cylinder usually passes through a period of time, and the foam and rubber are unstable.
7、針頭一般小于20針時可能會發(fā)生空氣問題——滴水或垂直流動，一般盡量使用較大的金屬針或錐形斜針，防止使用創(chuàng)口或鐵氟隆針。
7. Air problems may occur when needles are usually less than 20 needles - dripping or vertical flow. Generally, larger metal needles or tapered oblique needles should be used as far as possible to prevent the use of wounds or Teflon needles.
8、環(huán)氧樹脂(環(huán)氧樹脂)清洗機廠家提倡，我們盡可能每班都用一般甲苯溶劑儲存壓力缸自動清洗，越頻繁越好。
8. The manufacturer of Shenzhen Extension of Epoxy Resin (Epoxy Resin) Cleaning Machine advocates that we use general toluene solvent to store pressure cylinder for automatic cleaning in every shift, the more frequent the better.
