涂布机胶出量少或不出胶原因

Reasons for low or no adhesive output from the coating machine

　　涂布机可以将固体热熔胶加热熔融，经过精密齿轮泵将液态胶输送到浆料涂布装置，涂布在基材上。由于涂布机涂布工艺的原因，在涂布生产过程中也可能出现胶出量少或不出胶的现象。出现这种情况的原因有以下几种，我们分别来说：

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:

　　如果出胶压力下降，可以检查胶桶滤网，看是否被杂质堵塞，检查胶筒的控温系统，看是否出现故障。

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.

　　如果出胶大小不均匀，那么可能是滤网被堵住、马达运转不正常或者回流阀调整不当，可对应的进行调整。

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.

　　如果齿轮泵运行但不出胶，先看胶水熔化情况、滤网有没有被堵塞。如果是新设备，那么原因可能是热熔胶回路内真空造成的，这是要先拆掉胶管接头螺帽，让机器运转，待出胶正常后再装回去。

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.

　　如果是旧设备，那么有可能是齿轮泵齿轮已耗损，可以将齿轮泵取下来，换上一组新的齿轮。

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.
