Security checker troubleshooting precautions:

1.There are a large number of devices with a working voltage of 220V in the equipment, and ordinary maintenance must be carried out when the power is off.

2.There are a large number of precision electronic devices in the equipment, and preparations should be made to prevent static electricity from damaging the devices before maintenance;

3.The equipment has a lead protective layer to prevent radiation leakage, it is best to wear cotton gloves during operation, and if you cannot wear gloves, wash your hands immediately after work; 4.Before the equipment is powered on, it should be carefully checked to confirm that the wiring is correct and there is no misconnection or short circuit;

5.Before turning on the rays, cover the plate to avoid personal injury caused by the rays.

1. Unable to absorb material, plugging material, and low conveying capacity.

There are many reasons for the inability to absorb the material, the blockage of the material, and the low conveying capacity

1.Poor material characteristics.

The material is easy to bond and bridging, has poor fluidity, and is hygroscopic.

Scheme: add vibration, vulcanization, stirring and other designs (suitable for materials with a water content of no more than 10%) 2Replaced with new materials.

The specific gravity of the replaced material is quite different, and the characteristics of the material such as fluidity are quite different.

For example, if the system used to transport copper powder is used to transport toner, the transportation efficiency will be reduced by about 70%Solution: Different materials are transported in different systems and pipelines.

3.The dust removal effect is not good.

Due to the serious ash on the surface area of the filter element or bag, the filtration area is seriously reduced, resulting in the problem of reduced conveying capacity or material blockage.

Solution: Use compressed air to clean the filter element, and if possible, you can use ultrasonic cleaning to directly use the system's built-in backflush function for cleaning.

4.The supply volume is unstable.

The main factor of the instability of the supply volume is the use of the material gun feeding, and the manual operation causes the instability of the system feeding volume.

For specific analysis, please see: Advantages and defects analysis scheme of vacuum feeder material gun: 1. Material gun: manually operate the material gun to control the feed amount of the material gun mouth 2. Improve the plan, directly change to pipeline transportation.

5.The vacuum loader has too much material.

Too much material is stored in the hopper of the vacuum feeder, or the material is not discharged in time, which can easily lead to damage to the filter element, plugging or reducing the conveying capacity.

Solution: Extend the unloading time.

Manual operating system, separate discharge.

6.Excessive impurities in the material.

Solution: Add a screening process before the conveying process.

2. Dusting. 1. Spray powder at the outlet of the vacuum pump.

This is mainly caused by damage to the filter or bag collector or loose connections.

Scenario: Check the filtration system immediately.

2. Spray powder at the feed port during backblowing.

Relying on the back-blowing system of high-pressure airflow, if the sealing is not good, it is easy to form a powder spraying scheme: 1. Check whether the sealing ring is damaged and whether the installation method is correct 2. Increase the suction valve.

1. When the vacuum feeder is in use, the compressed air connection of the automatic vacuum feeder is that the insufficient pressure of the compressed air supply will lead to the lack of backflushing strength, which will lead to the dust summarized by the filter of the automatic vacuum feeder cannot be cleaned, thus affecting the suction speed of the vacuum feeder;

2. The pipe connection of the automatic vacuum feeder needs to be firm to prevent air leakage from affecting the vacuum degree;

3. The barrel ring of the vacuum automatic vacuum feeder is installed in place, check whether it is completely put into the S edge, if there is any damage, it should be replaced in time to prevent air leakage from affecting the suction efficiency;

Common faults and solutions of trapeze sewing machine.

The common faults of the flyer are: jumper, broken wire, broken needle, sluggish feeding, no action of the motor, etc., fault phenomena and treatment methods

1. Jumper. There are two situations of jumper: 1. Jumper during sewing 2. Single line after sewing is completed.

1. Reasons for jumpers in the sewing process: The gap between the needle and the hook needle is too large, the sewing bag is too thin, the needleboard hole is worn, the sewing thread is elastic, the sewing thread is not overpressed, and the groove surface of the needle is not parallel to the face of the fuselage.
