雙組份打膠機(jī)低成本的五種清洗方法
1.打膠機(jī)：針頭和塞子的彎曲或磨損會對點膠質(zhì)量產(chǎn)生重大影響。如果溫度高或長時間不清洗，貼片膠也可能在針頭內(nèi)表面固化或半固化，造成堵塞。定期檢查打膠機(jī)頭，發(fā)現(xiàn)污染，及時清理。將針頭浸泡在兼容的溶劑中是一種常見的方法，但單獨浸泡的效率太低，無法去除所有未固化的材料。可以用兼容溶劑的高壓噴霧將膠水從針頭內(nèi)孔吹出，然后用干燥的壓縮空氣將膠水吹出內(nèi)孔，使針頭干燥。
1. glue applicator: the bending or wear of the needle and plug will have a significant impact on the dispensing quality. If the temperature is high or it is not cleaned for a long time, the patch adhesive may also solidify or semi solidify on the inner surface of the needle, causing blockage. Regularly check the glue applicator head, and clean it up in time if any pollution is found. Soaking the needle in a compatible solvent is a common method, but soaking alone is too inefficient to remove all uncured material. The glue can be blown out of the inner hole of the needle with a high-pressure spray of compatible solvent, and then the glue can be blown out of the inner hole with dry compressed air to dry the needle.
2、金屬模板：為了避免清潔劑侵蝕模板和絲網(wǎng)的粘合劑，使用預(yù)洗工藝，使用更強(qiáng)的清潔劑，手動操作，避免清潔劑和粘合劑接觸，然后清洗模板用普通洗滌劑。
2. Metal formwork: in order to avoid the adhesive of formwork and wire mesh eroded by detergent, use pre washing process, use stronger detergent, operate manually to avoid the contact between detergent and adhesive, and then clean the formwork with common detergent.
3、塑料網(wǎng)板：清洗塑料網(wǎng)板時，可能會發(fā)生靜電放電。因此，應(yīng)使用特殊的抗靜電清潔劑來避免這種現(xiàn)象。同時，不要用抹布用手清潔，因為塑料很容易劃傷，長此以往可能會造成打印質(zhì)量問題。點膠機(jī)的清潔是點膠機(jī)日常維護(hù)中的一項重要工作。用戶對此非常重視，但清潔方法仍需改進(jìn)。
3. Plastic screen: electrostatic discharge may occur when cleaning the plastic screen. Therefore, special antistatic cleaners should be used to avoid this phenomenon. At the same time, do not use a rag to clean by hand, because the plastic is easy to scratch, which may cause printing quality problems in the long run. The cleaning of dispensing machine is an important work in the daily maintenance of dispensing machine. Users attach great importance to this, but the cleaning method still needs to be improved.
4、
雙組份打膠機(jī)出膠時，應(yīng)有一定成分，使新膠管中的膠水能順利流出膠頭。公認(rèn)膠閥的壓力和速度是按理想情況設(shè)定的。然后測量膠體流速，直到連續(xù)兩次測量的誤差在計劃的正負(fù)2%范圍內(nèi)。
4. When the two-component glue applicator delivers glue, it should have certain ingredients to make the glue in the new hose flow out of the glue head smoothly. It is generally accepted that the pressure and speed of the rubber valve are set according to the ideal situation. Then measure the colloid flow rate until the error of two consecutive measurements is within the planned range of plus or minus 2%.
其余還應(yīng)注意，如遇以下情況，建議不要使用粗略的純膠管更換方法：膠管內(nèi)的膠水在點膠機(jī)運行過程中已經(jīng)用完。在這種情況下，分配閥很可能有大氣。軟管中的膠水已超過使用時間。在上述情況下，您需要徹底清潔剛性分配閥或分配泵，并按照設(shè)備程序進(jìn)行操作。
It should also be noted that in the following cases, it is recommended not to use the rough replacement method of pure rubber hose: the glue in the hose has been used up during the operation of the dispenser. In this case, the distribution valve is likely to have atmosphere. The glue in the hose has expired. In the above cases, you need to thoroughly clean the rigid distribution valve or distribution pump and follow the equipment procedures.
5、快干膠（速干膠）堵在灌膠機(jī)膠閥的連接頭和管路上：這種情況主要是體內(nèi)水分過多或快干膠多次重復(fù)使用，應(yīng)使用新鮮的速干膠。對于干膠，用體內(nèi)不含水分的甲苯徹底清洗管道。應(yīng)用的氣體應(yīng)徹底干燥，過濾裝置應(yīng)在出廠時在氣壓和閥門系統(tǒng)軟件之間進(jìn)行修改。
5. The quick drying glue (quick drying glue) is blocked on the connector and pipeline of the glue valve of the glue dispenser: This is mainly due to excessive water in the body or repeated use of the quick drying glue. Fresh quick drying glue should be used. For dry glue, thoroughly clean the pipe with toluene that does not contain water in the body. The applied gas shall be thoroughly dried, and the filtering device shall be modified between the air pressure and the valve system software at the factory.
