Common Faults and Solutions of Compound Fertilizer Ammonium Chloride Granule Packaging Machine

The compound fertilizer ammonium chloride granule packaging machine is a packaging equipment widely used in multiple fields such as agriculture, medicine, food, and daily chemicals. It is mainly used for packaging various granular materials. The packaging weight range is generally between twenty and twenty-five kilograms, featuring high working efficiency and low energy consumption.

Common Faults and Solutions of Compound Fertilizer Ammonium Chloride Granule Packaging Machine

I. Issues Related to Packaging Materials

Excessive joints, cracks or burrs: These substandard packaging materials will affect the packaging effect and need to be replaced in a timely manner.

II. Electrical Faults

1、Paper supply motor circuit problem

Paper feed motor circuit failure or poor contact: Check and repair the paper feed motor circuit to ensure it works properly.

The paper supply proximity switch is damaged: Replace the damaged proximity switch to ensure the normal operation of the paper supply function.

2. Sealing system issues

Poor sealing of the bag: This may be caused by uneven inner layers of the packaging material, uneven sealing pressure, or low heat sealing temperature. Adjusting the sealing pressure and increasing the heat sealing temperature can solve this problem.

Misaligned sealing path: Re-adjust the position of the heat sealer body to ensure the sealing path is correct.

3. The bag cutting position is incorrect.

The position of the photoelectric switch (electric eye) is incorrect: Adjust the position of the photoelectric switch to ensure the bag cutting position is accurate.

III. Color Mark Positioning and Photoelectric Tracking Compensation Out of Control

When there are seams or rough edges on the packaging material, clean the former to ensure smooth paper feeding.

There are foreign objects in the former: Remove the foreign objects to ensure smooth paper feeding.

The packaging material protrudes from the guide plate of the photoelectric switch: Adjust the position of the guide plate so that the light spot is in the middle of the color mark.

Poor sensitivity of the photoelectric switch: Replace the photoelectric switch and correctly select the light-dark moving switch.

IV. Mechanical Faults

1、Fault in the turntable area

Foreign materials mixed into the heat-sealing area: Adjust the connection of the turntable gear and change the meshing position to prevent the materials from falling.

The adjusted blanking time has gone awry: re-fix the turntable, adjust the key and screws, and ensure the opener works properly.

2. Fault of the cutting knife

Bag cutting knife failure: Check if the sharpness of the cutting knife is sufficient. Replace the cutting knife head or adjust the gap in the middle of the transverse seal if necessary.

The packaging bags cannot be cut or are partially uncut: Adjust the pressure between the cutting knives, and sharpen or replace the cutting knives.

V. The Problem of Non-Drawing Bags

The bag-pulling motor does not operate: Check if the circuit, proximity switch, controller and stepper motor are damaged, and replace the damaged parts.

VI. Other Common Faults

The heat sealer body does not heat up: This may be caused by damaged heating tubes, circuit faults, blown fuses, faulty temperature controllers or open circuits in the thermocouple, etc. Replace the corresponding parts according to the specific situation.

In conclusion, the maintenance of the compound fertilizer ammonium chloride granule packaging machine requires regular inspection and prompt handling of various malfunctions to ensure the normal operation of the equipment and production efficiency.
