A Guide to Purchasing Automatic Fertilizer Traction and Sewing Packaging Machines

When choosing an automatic fertilizer traction bag sewing and packaging machine, the main considerations are the sewing speed, durability and adaptability to bag types. The price is generally between 30,000 and 80,000 yuan. Let me tell you in the simplest plain language how to choose:

First, look at the type of your bag

Woven bags (common fertilizer bags) : Choose industrial-grade sewing machine heads, and the stitches should be thick (to prevent thread breakage).

Paper-plastic composite bags: Choose double-thread sewing to avoid material leakage.

Valve pocket (automatic filling) : It should be equipped with heat sealing or bonding, not necessarily using a sewing machine.

2. Key points for selection

Bag sewing speed:

Standard type: 2 to 3 packs per minute (suitable for small factories, 30,000 to 40,000)

High-speed type: 8 to 10 packs per minute (for high-production lines, 50,000 to 80,000)

Durability: Don't break down after one year of use

Check the motor: The motor is the heart of the machine. Choose one with pure copper coils instead of aluminum ones, as they are prone to burning out.

Check the bearings: The bearings of the traction wheel must be imported, such as NSK or SKF. Do not use unbranded ones, as they will shake after long-term use.

Check the sewing head: The sewing head should be a double-needle one to ensure a firm stitch. Do not use a single-needle one as it is prone to thread detachment.

Degree of automation

Semi-automatic: Manual bag placement, machine automatic sewing (cheap, about 30,000 yuan).

Fully automatic: Automatic bag picking, sewing, and line cutting (labor-saving, over 60,000 yuan).

Dust-proof design

There is a lot of fertilizer dust, so the machine should be equipped with a dust cover; otherwise, the sewing machine is prone to thread jamming.

3. Price reference

Type | Speed (package/minute)  | Price (yuan)    | Suitable Scenarios  |

Semi-automatic standard type   | 20,000-30,000   | 30,000-40,000       | Small factory, low budget

Semi-automatic high-speed type | 80,000-100,000  | 30,000-50,000       | Medium output

Fully automatic type           | 100,000-150,000 | 60,000-80,000       | Big factory, labor-saving

Look at the cost performance: Don't just go for the cheapest ones, nor just buy the expensive ones. Generally, the price of mid-range machines ranges from 30,000 to 50,000 yuan, while that of high-end ones is between 50,000 and 80,000 yuan.

4. Guide to Avoiding Pitfalls

⚠️ Don 't be greedy for CHEAP: under 20,000, the sewing machine is basically a household machine modified, sewing fertilizer bag will be ruined in a month.

⚠️ Look for after-sales service: Ask how long the needle, motor and other vulnerable parts are covered by warranty and how much it costs to replace them.

⚠️ Test: Take your fertilizer bag and sew it on the spot to see if the thread breaks or the needle jumps.

Summary

For small factories with a limited budget: Choose a semi-automatic fertilizer traction sewing and packaging machine, which can be settled for 30,000 yuan.

High output: Directly use the fully automatic fertilizer traction sewing and packaging machine, 60,000 to 80,000 yuan, more cost-effective in the long run.
