Maintenance tips for dispensing machines: How to prevent fluid drips and blockages in dispensing machines?
Automatic dispensing machine as the core equipment in the gluing process, its application is becoming more and more widespread. However, in the actual production process, automatic dispenser often fluid drips and blockages in dispensing machines, which not only affects the effect of glue, but also may be a potential threat to the quality of automotive parts.
Automatic dispenser machine fluid drips and blockages in dispensing machines cause analysis, automatic dispensing machine at the end of the dispensing operation of the fluid drips and blockages in dispensing machines, mainly from the glue flow characteristics, equipment operating parameters and machine status and other factors. Specifically, including the following aspects:

1.Glue characteristics:
glue viscosity, fluidity and curing speed and other characteristics will directly affect the phenomenon of fluid drips and blockages in dispensing machines. High viscosity of the glue in the stop flow is more likely to form fluid drips and blockages, and good fluidity of the glue may be due to the flow rate is too fast and produce fluid drips in the stop.
2.Equipment operating parameters:
improper setting of the delay time for opening and closing the glue, irrational setting of the fluid drips height and lifting height, unstable or too high air pressure setting, and the distance between the needle and the workpiece is too close or too far, etc., which may affect the flow of the glue and the breakage, which may lead to the fluid drips phenomenon.
3.Machine status:
wear and tear, clogging or contamination of the dispensing head or needle, as well as insufficient regular maintenance and upkeep of the equipment, such as incomplete cleaning of the pipeline, unstable air pressure system, etc., may also lead to fluid drips and blockages problems.
Automatic glue dispensing machine fluid drips and blockages in dispensing machines solution, for automatic dispenser fluid drips and blockages problem, you can take the following solutions:
1. Adjust the characteristics of the glue:
according to the product process needs to choose the right glue, to ensure that the viscosity of the glue is moderate, neither too thick nor too thin. For high-viscosity glue, can be diluted or heated to enhance its fluidity, to help reduce the phenomenon of fluid drips and blockages.
2. Optimize the operating parameters of the equipment:
Reasonably set the delay time for opening and closing the glue, to ensure that the glue in the stable outflow before starting the dispensing work, as well as in the dispensing is completed after a period of delay before closing the glue head. At the same time, adjust the fluid drips height and lifting height, so that the dispensing head can effectively pull off the glue when lifting.
In addition, keep the air pressure stable and moderate, to avoid too high or unstable air pressure caused by the fluid drips and blockages phenomenon.
3. Choose the right needle:
according to the size of the product and the viscosity of the glue to choose the right dispensing needle, to ensure that the caliber of the needle is neither too small nor too large, in order to reduce the resistance of the glue outflow and fluid drips phenomenon. At the same time, regularly check the status of the needle to ensure that the needle is not clogged or worn.
The solution to the problem of fluid drips and blockages in dispensing machines, for automatic dispenser fluid drips and blockages, you can take the following solutions:
1. Adjust the characteristics of the glue: according to the product process needs to choose the right glue, to ensure that the viscosity of the glue is moderate, neither too thick nor too thin. For high-viscosity glue, can be diluted or heated to enhance its fluidity, to help reduce the phenomenon of fluid drips and blockages.
2. Optimize the operating parameters of the equipment:
Reasonably set the delay time for opening and closing the glue, to ensure that the glue in the stable outflow before starting the dispensing work, as well as in the dispensing is completed after a period of delay before closing the glue head. At the same time, adjust the drawing height and lifting height, so that the dispensing head can effectively pull off the glue when lifting.
In addition, keep the air pressure stable and moderate, to avoid too high or unstable air pressure caused by the fluid drips and blockages phenomenon.
3. Choose the right needle:
according to the size of the product and the viscosity of the glue to choose the right dispensing needle, to ensure that the caliber of the needle is neither too small nor too large, in order to reduce the resistance of the glue outflow and fluid drips and blockages phenomenon. At the same time, regularly check the status of the needle to ensure that the needle is not blocked or worn.
4.Strengthen the maintenance of equipment:
regular cleaning and maintenance of equipment to ensure that the pipeline is unobstructed, stable and reliable air pressure system. For serious wear and tear of the dispensing head or needle, should be replaced in a timely manner.
5.Improve the process:
In the dispensing process, you can take the segmented dispensing, early off the glue reserved for the completion of the final track, slanting pull on the lift and other process improvement measures to reduce the occurrence of fluid drips and blockages the phenomenon.
