涂布機膠出量少或不出膠原因

Reasons for low or no adhesive output from the coating machine

　　涂布機可以將固體熱熔膠加熱熔融，經過精密齒輪泵將液態膠輸送到漿料涂布裝置，涂布在基材上。由于涂布機涂布工藝的原因，在涂布生產過程中也可能出現膠出量少或不出膠的現象。出現這種情況的原因有以下幾種，我們分別來說：

The coating machine can heat and melt solid hot melt adhesive, and then deliver the liquid adhesive to the slurry coating device through a precision gear pump for coating on the substrate. Due to the coating process of the coating machine, there may also be a phenomenon of low or no glue output during the coating production process. There are several reasons for this situation, let's talk about them separately:

　　如果出膠壓力下降，可以檢查膠桶濾網，看是否被雜質堵塞，檢查膠筒的控溫系統，看是否出現故障。

If the glue pressure drops, you can check the filter screen of the glue barrel to see if it is blocked by impurities, and check the temperature control system of the glue barrel to see if there is a malfunction.

　　如果出膠大小不均勻，那么可能是濾網被堵住、馬達運轉不正常或者回流閥調整不當，可對應的進行調整。

If the adhesive size is uneven, it may be due to the filter being blocked, the motor not running properly, or the reflux valve being adjusted improperly. Corresponding adjustments can be made.

　　如果齒輪泵運行但不出膠，先看膠水熔化情況、濾網有沒有被堵塞。如果是新設備，那么原因可能是熱熔膠回路內真空造成的，這是要先拆掉膠管接頭螺帽，讓機器運轉，待出膠正常后再裝回去。

If the gear pump is running but does not produce glue, first check the melting of the glue and whether the filter screen is blocked. If it is a new device, the reason may be due to vacuum in the hot melt adhesive circuit. This requires first removing the nut of the adhesive pipe joint, allowing the machine to operate, and then reinstalling it after the adhesive is discharged normally.

　　如果是舊設備，那么有可能是齒輪泵齒輪已耗損，可以將齒輪泵取下來，換上一組新的齒輪。

If it is an old equipment, it is possible that the gear of the gear pump has been worn out. The gear pump can be removed and replaced with a new set of gears.
