The replaceable pot coating machine, with its flexibility of "replaceable pot body", adapts to the coating processing needs of multiple specifications of materials and is widely used in tablet coating (such as enteric coating, thin film coating), food granule coating (such as candy, health product granules) and other scenarios. The coating process requires precise control of parameters such as pot rotation speed, spray volume, temperature, etc. If equipment malfunctions, it can easily lead to uneven coating, material adhesion, and coating layer detachment, affecting the appearance and quality of the product. Therefore, mastering the solutions to common problems is crucial to ensure production.
The common problems and solutions of interchangeable pot coating machines are as follows:
1、 Mechanical malfunction
1. The machine cannot start (the blades cannot be turned by hand)
Reason: There is a problem with the bearing.
Solution: Consider replacing the bearings.
2. Belt breakage
Reason: The belt tension is not suitable.
Solution: Check the tightness of the belt and adjust the tensioning wheel to tighten the belt in a timely manner.
2、 Motor malfunction
1. The machine cannot start (capacitor issue)
Reason: The capacitor is burnt out.
Solution: Replace the starting capacitor and running capacitor, and replace the power cord with a thicker and shorter one.
2. The machine cannot start (motor burnt)
Reason: The motor has a serious malfunction.
Solution: Contact the manufacturer's after-sales service in a timely manner.
3、 Inverter malfunction
1. The machine cannot adjust speed (the potentiometer setting screw is loose)
Reason: The potentiometer can rotate once, but the speed cannot be adjusted because the potentiometer's fixing screw is loose.
Solution: Re tighten the screws.
2. The machine cannot adjust speed (potentiometer damaged)
Reason: The potentiometer can rotate several times but the speed cannot be adjusted, indicating that the potentiometer is damaged.
Solution: Replace the potentiometer.
3. The machine cannot adjust speed (with fault code displayed)
Reason: The frequency converter has experienced related malfunctions.
Solution: Follow the fault code prompts to troubleshoot.
4. Uneven speed regulation of the machine
Reason: The wiring of the potentiometer circuit is incorrect.
Solution: Swap the x1 and+10v connectors on the frequency converter.
4、 Material handling issues
1. Uneven coating
Reason: The seed flow rate and the liquid flow rate do not match.
Solution: Check the seed flow rate and medication flow rate to ensure that the seed and medication flow rates match.
2. Leakage of medication (leakage at the delivery end)
Reason: Mismatched drug flow rate or failure to shut down the peristaltic pump in a timely manner.
Solution: Adjust the matching degree of drug flow rate and promptly turn off the peristaltic pump. Generally, a small amount of leakage is a self-protection phenomenon of the machine, which is to prevent bearing damage.
3. Foreign objects entering
Reason: There are foreign objects in the pipeline.
Solution: It is necessary to dismantle the pipeline for foreign object removal.
5、 Other issues
1. The machine has an electric shock sensation
Reason: The circuit is exposed; If there is no exposure, it may be the induced electricity of the peristaltic pump.
Solution: Check if the circuit is exposed. If it is not exposed, the leakage is caused by the induced electricity of the peristaltic pump, ensuring that the machine is well grounded.
2. The voltmeter is damaged
Reason: The voltmeter itself has malfunctioned.
Solution: Replace the voltmeter.
