Fertilizer automatic traction edge folding and sewing machine + single-person operation quantitative

Project Background: In the packaging process of fertilizers (granules/powders), the traditional manual bagging and sewing methods are inefficient (only 100-200 bags per hour), and the sealing quality is unstable. The combination of the automatic traction edge folding and sewing machine and the quantitative packaging scale can achieve high-precision weighing and automatic edge folding and sewing under single-person operation, significantly improving packaging efficiency (300-600 bags per hour) and sealing consistency. It is particularly suitable for large-scale packaging of products such as compound fertilizers, organic fertilizers, and microbial agents.

I. Core Equipment Functions and Advantages

Quantitative packaging scale (single-person operation type)

High-precision weighing: Utilizing loss-in-weight/dynamic weighing technology, with an error of ±0.1% to 0.2% (25-50kg per package).

Automated operation: A single person can complete the entire process of bag loading, bag clamping, filling and bag removal.

The touch screen sets parameters and supports the storage of over 10 types of formulas (such as fertilizer packaging of different specifications).

Suitable for complex materials: granular fertilizer (anti-breakage design) | Powdered fertilizer (dust-proof sealing) | Moist fertilizer (anti-sticking screw feeding).

2. Automatic traction edge folding and sewing machine

Fully automatic bag sewing: Automatically pull the packaging bag, fold the edge, and sew the opening (thread sewing/heat sealing is optional), no manual intervention is required.

Intelligent adjustment: It can adapt to different bag types (woven bags, PE bags, paper bags), and the bag width is adjustable from 30 to 60cm.

Variable frequency speed regulation, matching the discharging speed of the packaging scale (such as fast/slow dual-speed mode).

Durable design: Industrial-grade sewing machine head, capable of continuous operation for ≥8 hours per day.

Ii. System Workflow (Single-Person Operation)

1. Quantitative filling: The fertilizer is automatically weighed by the packaging scale and filled into bags.

2. Conveying and positioning: The filled bags are transported to the sewing machine by the conveyor belt and positioned by the photoelectric sensor.

3. Edge folding and sewing: Automatic edge folding and sewing (single/double thread sewing or heat sealing is available).

4. Finished product output: After the sewing of the bags is completed, they are conveyed to the palletizing area, and the entire process only requires one person to monitor.

Iii. Customer Cases and Benefit Analysis

Case: An organic fertilizer factory in Henan Province

Original process: 4 people operate (2 people weighing, 1 person holding the bags, and 1 person sewing the bags), with an efficiency of 200 bags per hour and a breakage rate of 5%.

After upgrade: Equipment combination: Zhengzhou Hanke Machinery HK-CW50 quantitative scale +HK-FS380 automatic sewing machine.

Effect: Efficiency has been increased to 450 packages per hour (operated by a single person), and labor costs have been reduced by 75%.

The qualified rate of seam openings is ≥99.5%, and the rate of broken packages has dropped to 0.3%.

Investment payback period: 6 to 8 months (calculated based on an average daily output of 80 tons).

Iv. Selection Suggestions

Demand scenario | Recommended configuration | Budget reference

Medium and small production capacity (≤300 packs per hour) | Semi-automatic quantitative scale + simple sewing machine | 80,000-150,000 yuan

Large-scale production (≥500 packs per hour) | Fully automatic scale + traction edge folding and sewing machine + conveyor line | 180,000-350,000 yuan

Highly corrosive fertilizer |316 stainless steel scale body + acid-resistant sewing machine | 250,000-500,000 yuan

V. Procurement Precautions

1. Material compatibility test: Provide fertilizer samples to verify the anti-sticking and dust-proof effects of the equipment.

2. After-sales service terms: Core components (sensors, sewing machine heads) are guaranteed for ≥1 year.

3. Energy efficiency and environmental protection: Choosing variable frequency motors can save energy by more than 30%. Equipped with a dust removal interface (in compliance with the GB16297 emission standard).

The combination of automatic traction edge folding and sewing machine and quantitative packaging scale is the preferred solution for upgrading fertilizer packaging, especially suitable for: For regions with high labor costs, export-grade products, and enterprises planning to apply for organic fertilizer certification (to reduce human errors), if you need further customized solutions or trial operation arrangements, we can provide parameters such as production capacity, bag type, and material characteristics. Zhengzhou Hanke Machinery will recommend a better configuration for you!
