What are the common problems that will occur during the use of the CNC PU foam sealing gasket machine？
The development of CNC PU foam sealing gasket machine is very rapid, after the use of CNC PU foam sealing gasket machine can replace manual work, to achieve mechanized production; Single machine can be operated, simple and convenient, high speed and accurate. However, if the operation is not proper or long time use may occur some problems, today we will take a look at what will appear common problems.
What is the CNC PU foam sealing gasket machine?
The CNC PU foam sealing gasket machine is an automated machine that specifically controls the fluid, drips, coats, and seals the liquid on the surface or inside the product.The CNC PU foam seal gasket machine is mainly used for glue, oil, paint and other liquid in product process. Note, coating, drip to the precise position of each product, can be used to achieve the dot, line, circular or arc.
The CNC PU foam sealing gasket machine mainly applies to all kinds of solvents, adhesives, oil, paint, chemical materials, solid glue, etc., including silicone, EMI conductive adhesive, UV glue, AB glue, fast drying glue, epoxy glue, sealant, grease, tin paste, transparent paint, screw fixant, ink, pigment, etc.
What is the function of the CNC PU foam seal gasket machine？
Simply put, the CNC PU foam seal gasket machine is specialized for the adhesive and other coatings control and drip, coated on the surface of the product automation equipment. It is through the compressed air to send the coating into the supply hose, and then through the program control, the coating in accordance with the preset path for drip or coating. Automatic control of the production process, without manual operation, improve the efficiency at the same time also reduce the labor intensity.
Common problems of CNC PU foam seal gasket machine
The most common problem encountered by theCNC PU foam seal gasket machine is the valve problem, and the following are effective ways to solve the problems that often occur when the rubber valve is used.
This situation often occurs after the rubber valve is closed. 95% of these cases are due to the use of small needle caliber.
Too small a needle will affect the flow of the liquid causing back pressure, resulting in the formation of a drip phenomenon shortly after the rubber valve is closed. Too small a needle will also affect the action of the exhaust bubble when the rubber valve begins to use. This problem can be solved simply by replacing a larger needle. Tapered oblique needles produce the least back pressure and the most fluid flow. The air in the liquid will leak after the rubber valve is closed, it is best to remove the air in the liquid in advance, or use the glue that is not easy to contain bubbles. Or use the glue after centrifuging and defoaming.
The size of the glue is inconsistent
When the glue is inconsistent, it is mainly caused by the instability of the pressure cylinder or the air pressure of the fluid storage.
The intake pressure regulator should be set 10 to 15psi lower than the minimum pressure in the factory. The pressure used in the pressure cylinder should be between the pressure above the middle of the regulator. The pressure should be avoided between the low pressure part of the pressure gauge.
The control pressure of the rubber valve should be at least 60psi above to ensure the stability of the rubber.
Finally, the glue time should be checked. If it is less than 15/1000 seconds, the glue will be unstable. The longer the glue time, the more stable the glue.
Flow rate is too slow
If the flow rate is too slow, change the pipe from 1/4 "to 3/8".
The pipe should be as short as possible if not needed.
In addition to changing the pipe, it is necessary to change the rubber mouth and air pressure, so as to completely accelerate the flow rate.
Bubbles in the fluid
Excessive fluid pressure coupled with too short opening time may seep air into the liquid. The solution is to reduce the fluid pressure and use a conical inclined needle.
Glue plugging
This situation is mainly due to excessive moisture or repeated use of instant glue. Be sure to use fresh instant glue. Clean the pipe thoroughly with Aceton acetone without moisture. The air used should be determined to be completely dry and a filter should be installed between the air pressure and the rubber valve system in the plant. (If the above methods are still ineffective, nitrogen should be used).
Reasons for breaking glue during dispensing
First: Check whether there is a problem with the glue (such as the glue contains bubbles, particulate sediment, etc.), in this case, the glue dispenser will produce glue breaking problems;
Second: Whether the gluing controller works normally, because of its abnormal work or its own performance is insufficient, there will be the problem of gluing broken glue.
UV adhesive
UV adhesive is UV curing adhesive.
Make sure to use black pipes.
Do not directly add UV glue to the old UV glue in the pressure cylinder. First, the original UV glue is discharged, and then the UV glue is poured into the empty pressure cylinder. The UV glue in the pressure cylinder often produces bubbles after a period of time, resulting in glue instability.
The price of CNC PU foam seal gasket machine
The price of the glue machine is subject to fluctuations of many factors, usually the price will be affected by raw materials, market environment, research and development costs, so there will often be different prices, if you want to know the latest price can contact me.
