How to solve the problem of bubbles after filling the glue?

How to solve the problem of bubbles after consolidation of glue: 

The main reason for causing bubbles when the glue filled is consolidated by the glue filling machine:

1. Air enters during stirring, and the air is not completely removed during the injection of the product and the entire hardener process. Phenomenon: Very small are the bubbles.

2. The reaction of moisture and hardener agent produces gas, phenomenon: Very large are the bubblesThe solution to the first cause of bubbles:
　　 It is recommended that after mixing the main agent and hardener agent together, use a double-liquid glue potting machine to vacuum it with a vacuum system.
　　Turn on the heating system of the glue filling machine, and preheating the product to be potted will let the air escape.

　　Harden the glue in a room with low temperature and humidity to let the air flee. 

The solution to the second cause of bubbles:

A. The main agent has been used many times, and moisture is mixed in each time during mixing. It may cause the bubbles when the lid of the package is not tightly closed. In order to find out the real reason, please follow the above instructions to mix the main agent and hardener agent in a dry cup and put it in an oven (60-80) to dry. If bubbles still occur, it means that the main agent has deteriorated at this time, so please do not use it again. 

B. The potting product contains too much moisture. It is recommended to re-test after preheating the product.

C, the surface of the mixture of the main agent and the hardener agent reacts with moisture in the surrounding air. If this is the case, please cure in a dry environment. If the product permits, it can be cured in an oven after heating,

D. The liquid main agent and hardener agent mixture may have been in contact with other chemicals (such as solvents, release agents, varnishes, glues, etc.) before hardener. Ensure that these substances are removed before the next test

The easiest way to solve the bubble filling is to use a vacuum filling machine. 

Vacuum glue filling machine is a kind of equipment for filling glue in a vacuum environment. Compared with ordinary glue filling machines, the biggest difference lies in the vacuum, that is, the glue is defoamed to ensure that there are no bubbles in the glue. The main application industries are LED flexible light bar industry, automobile ignition coil, LED power supply, etc.

There are currently two types of vacuum glue filling machines: one is a fully automatic vacuum filling machine, and the other is a semi-automatic one.

Automatic vacuum glue filling machine is to continuously defoam the glue, including the entire glue filling environment is carried out in a vacuum environment, that is, the robot part of the glue filling machine is made into a full vacuum environment. This kind of glue filling machine is generally used for the glue filling of ignition coils, dry-type transformers and medium and high voltage transformers, that is, the product glue should not have any air bubbles.

How to do trouble shooting for VFFS vertical packaging machine

Automatic packaging machines are the most commonly used and indispensable special packaging equipment in the production process in the factory. During long-term operation, if there is the failure and abnormal shutdown, it will cause losses to the manufacturer. For this reason, the user's on-site operators , Maintenance personnel should be familiar with the correct operating procedures of the packaging machine in order to avoid damage of the wrong operation to the machine; At the same time is is a must to know how to regularly maintain and repair the mechanical and electrical parts of the equipment. Users can refer to the common faults of the automatic packaging machine and the corresponding repair solutions to repair the equipment.

Common faults and maintenance solutions of automatic packaging machines

        1. The seal of the horizontal or vertical seal is damaged
Check whether the setting temperature is too high, or the packaging speed is too slow, and the sealing time is too long, which will cause the film to burn. The temperature should not be too high when the sealing is intact. If the sealing part is still not stretched or wrinkled after repeated attempts, the material of the packaging film itself should be considered.

        2. The length of the packaging bag destroys the printed pattern
The cross-sealing cutter is sealed and cut off at the color code to ensure that the packaging film that is too light in the color of the non-color code block is driven to slip. After this situation is eliminated, the photoelectric eye color code recognition sensitivity should be adjusted, and the color code tracking is started in the device function menu. Adjust according to the color code debugging method guided by the technical engineer.
         3. Unable to seal or the seal is not firm
First, rule out whether the horizontal sealing temperature setting is too low, and increase the sealing temperature setting appropriately. If the sealing still leaks, you need to consider abnormal conditions such as solid-state circuit breaker, temperature control module, thermocouple damage, etc., and gradually check and confirm which link has the problem, and timely Replace damaged parts. If the packaging speed is set too fast, it will also cause sealing problems. At this time, the packaging speed should be appropriately reduced.

The packaging machine troubleshooting  

▶Packing machine fault phenomenon Packing equipment fault diagnosis Packing machine repair fault solution

▶There is no response after starting the machine and the machine cannot be turned on. Check whether the emergency stop switch is reset. Reset the emergency stop switch.
Turn off the main power and turn it on again after 20 seconds
▶Leakage switch tripped, heating tube and other electrical equipment leakage, check each electrical appliance one by one
▶The sealing temperature cannot rise up. The power-off protector has tripped. Check and remove the short circuit, then close it again.
▶The heating tube is burned out. Replace the heating tube.
▶The temperature control meter is damaged. Replace the temperature control meter.
▶The temperature of the temperature control meter repeatedly bounces. The thermocouple is loose or damaged. Tighten or replace the thermocouple.
▶The temperature is normal when the machine is stopped but the temperature drops after the machine is turned on. The low voltage causes the power of the heating tube to decrease. Reduce the packaging speed or increase the voltage stabilizing device
▶The power of the heating tube is too small. Replace the high-power heating tube.
▶The seal of the packaging bag leaks and the temperature is not enough. Increase the temperature appropriately
▶Insufficient pressure Check whether the total pressure is 6.5 kg
▶The sealing time is too short Increase the sealing time parameter appropriately
▶The front and rear horizontal sealing rollers are not flat. Carefully adjust the sealing parallelism of the horizontal sealing rollers.
▶Clamping adjust the blanking time or inflation delay
▶Unable to control the cut point or half point. Wrinkles on the edge of the packaging film or optical path quality problems cause photoelectric malfunction. Replace the packaging film.
▶The sensitivity of the photoelectric eye has not been adjusted properly. Re-adjust the photoelectric sensitivity
▶Setting the bag length is not enough to cause the length of the bag. Increase the bag length
▶Abnormal film pulling The pressure of the film transport cylinder is not enough or too large. Check whether the pressure of the film transport is 2.5 kg.
▶Belt slippage or damage Use a saw blade to scrape the surface of the fur belt or replace the belt
▶The packaging film has too much static electricity. Replace the packaging film.
