Common fault handling solutions for the clamping mechanism of 25-kilogram bacterial fertilizer packa

The clamping mechanism of the 25-kilogram bacterial fertilizer packaging scale is a key component of the packaging scale. Its design directly affects the packaging efficiency and sealing performance. Common types include fully enclosed type, simple side clamping type and internal support type. The specific features and applications are as follows:

I. Core Requirements of Microbial Fertilizer Inclusion Mechanism

1. Special challenges

Bacterial fertilizer is prone to dust → A sealed dust-proof design is required

The packaging bags are made of various materials (PE/ woven bags/laminated bags) → They need to adapt to the clamping force

Live bacteria protection → Avoid mechanical compression causing the death of the bacterial community

Ii. Comparison of Mainstream Sandwich Mechanism Types

Type: Mechanical type, Pneumatic type, electric servo type

Clamping force: Fixed (20-50kg), adjustable (10-80kg), intelligent dynamic adjustment

Adapted bag types: Only standard bags available; suitable for both thick and thin bags; customizable for special-shaped bags

Dust-proof design: No basic dust-proof, fully sealed + dust removal interface

Microbiota protection: Poor, medium, best (flexible contact

Price: 8,000-15,000 yuan, 15,000-30,000 yuan, 30,000-50,000 yuan +

✅ bacterial fertilizer recommendation: pneumatic type (mid-range) or electric servo type (high-end)

Iii. Key Technologies of Special Clamping Mechanism for Bacterial Fertilizer

Triple anti-pollution design

Food-grade silicone grippers (corrosion-resistant and easy to clean)

Negative pressure dust suction interface (directly connected to the dust removal system)

Ultraviolet disinfection optional (biosafety type)

2. Intelligent pressure control

Real-time feedback of pressure sensor (anti-bag breakage)

Automatically remember parameters for different bag thicknesses

3. Special structure optimization

Arc-shaped claw design → Reduces wrinkles at the bag opening

Quick-release structure → Convenient for sterilization treatment

Iv. Typical Fault Handling Solutions

Fault phenomenon: Possible causes: Solutions

Bag clamping is not secure. Insufficient air pressure (<0.4MPa). Check the air compressor and adjust the pressure

Bag opening contamination, residual fertilizer on the gripper, wipe daily with 75% alcohol

Action delay: Solenoid valve blockage: Clean the air filter every month

High bag breakage rate; Excessive clamping force; recalibrate the pressure curve

V. Suggestions for Selection and Configuration

1. Mandatory configuration

304 stainless steel body (anti-bacterial fertilizer corrosion)

Abnormal pressure alarm function

Photoelectric protection against accidental clamping

2. Value-added optional

Bag opening shaping device (solving soft package collapse)

Weighing linkage system (Automatic peeling when bag clamping)

Internet of Things module (Remote monitoring of packet inclusion times)

Choosing the right clamping mechanism can increase the packaging efficiency of microbial fertilizer by 40%!
