HF Welding Document Bag Making Machine

Product Introduction

When office supplies factories mass-produce PVC document bags, they often face low productivity due to asynchronous feeding/welding of single-station equipment, and slow mold replacement affecting order delivery. HF Welding Document Bag Making Machine is designed for mass production of document bags. Through alternate operation of dual slide tables (one slide table welds while the other feeds synchronously), productivity is increased by 60% compared to single-station equipment; paired with quick-change molds for document bags, A4/A5 specifications can be switched in 5 minutes. At the same time, dual-circuit temperature control ensures flat, bubble-free welding of both thin and thick materials, fully adapting to the efficient mass production needs of document bags.

Product Features

Dual Slide Table Alternate Operation: Two slide tables run independently, welding and feeding are carried out synchronously, with an hourly productivity of 800-1200 document bags, 60% more efficient than single-station equipment.

Quick-Change Molds for Document Bags: Custom quick-install molds for A4/A5/file bag specifications, replaced in 5 minutes via a snap-on structure without disassembling equipment components, adapting to multi-spec small-batch orders.

Dual-Circuit Independent Temperature Control: Two slide tables are equipped with independent temperature control circuits, allowing simultaneous welding of PVC materials of different thicknesses (e.g., 0.5mm thin document bags + 1.2mm thick file bags), avoiding parameter interference and reducing setup time.

Application Scenarios

Dual Slide Table Mass Production of PVC Document Bags: Suitable for efficient welding of zipper document bags, snap file bags, and transparent sealed document bags. It solves the pain points of traditional single-station equipment such as "low productivity, slow mold change, and poor efficiency in multi-spec production". Alternate operation of dual slide tables increases productivity, quick-change molds adapt to multi-spec orders, and dual-circuit temperature control ensures welding quality of materials of different thicknesses, helping office supplies factories undertake larger batches of document bag orders and reduce unit product production costs.

FAQ

1.Can different specifications of document bags be produced when dual slide tables operate simultaneously?

A: Yes. The two slide tables are equipped with independent temperature control and quick-change molds, which can be loaded with A4 and A5 molds at the same time, producing two different sizes of document bags synchronously, adapting to multi-spec mixed orders.

2.How much higher is the productivity of dual slide table alternate operation compared to single-station equipment?

A: Productivity is increased by about 60%. Single-station equipment takes 5-8 seconds per piece for feeding + welding, while dual slide table equipment feeds on one slide table while welding on the other, producing 800-1200 pieces per hour, 300-500 more than single-station.

3.Does changing document bag molds require professional tools?

A: No professional tools are needed. The mold adopts a snap-on quick-install structure; the old mold can be removed by manually unlocking the snap, and the new mold is locked after installation, completed within 5 minutes, operable by novices.

4.When welding 0.5mm thin material and 1.2mm thick material at the same time, will parameters interfere with each other?

A: No interference. The dual-circuit independent temperature control system allows independent storage of temperature and power parameters for the two slide tables, and the welding parameters of thin and thick materials do not affect each other, enabling stable synchronous production.

5.Will the equipment fail when the dual slide tables run continuously for 8 hours?

A: No. The slide tables use wear-resistant guide rails + heat-dissipating bearings, which can maintain stable accuracy even after 8 hours of continuous operation. Paired with a natural air cooling system, welding effect will not be affected by overheating.

6.Can special-sized document bag molds be customized?

A: Yes, customization is available. Custom quick-install molds are supported for special specifications such as long file bags and special-shaped document bags, which can be directly snap-mounted on the slide tables without modifying the equipment.

7.Is the operation of dual slide tables difficult, and how many people are needed to operate?

A: Operation is simple, and 1 person is sufficient. The slide tables are equipped with positioning fixture slots; feeding can be done by direct clamping, and the slide table working mode is switched via a knob. 1 person can complete feeding and welding for both slide tables.

8.What is the load-bearing capacity of the zipper of the welded document bag?

A: The load-bearing capacity can reach 3KG. The 350KG (500KG) pressure of the dual slide tables combined with temperature-controlled welding makes the welding strength of the zipper and bag body reach 95% of the raw material, and the zipper will not fall off even when pulled with 3KG of documents inside.
