Part 1: Three-Paper One-Film Flexographic Printing Machine

ZYT-6 FLEXO PRINTING MACHINE

Product Structure Overview

This machine uses a synchronous belt drive system connected to a hardened gear gearbox on the main motor. Each printing unit is equipped with a synchronous belt transmission and a high-precision planetary gearbox, along with an impression roller driven by a gear system that allows 360° printing plate adjustment.

An extended cooling section after the printing process enables the ink to dry optimally while ensuring the material is thoroughly cooled. This results in improved and more stable print quality.

Control System

The main motor is equipped with an inverter for stable and efficient speed control.
A PLC touchscreen (Human Machine Interface) is used to operate and control the entire machine system.
The machine is also equipped with high-quality gearbox motors.

There are 6 independent ink supply systems to ensure consistent ink distribution for each printing color.

Unwinding System (Material Unwinding Unit)

Single workstation design.
Shaftless structure.
Hydraulic clamping and hydraulic lifting system for material loading.
The unwinding width can be adjusted hydraulically to the left or right according to production requirements.
Automatic tension control using a magnetic powder brake.
Automatic web alignment system using photoelectric sensors to maintain accurate material tracking during operation.

Part 2: Three-Paper-One-Film Center-Seam Paper Bag Gluing Machine

Application

This machine is specifically designed for producing multi-layer paper bags with a structure consisting of three layers of paper and one layer of PE film. The materials include printed paper tubes with logos and colored packaging designs, additional lining paper tubes, and PE film rolls, each loaded on separate unwinding stations.

The production process includes:

• Automatic material feeding
• Multi-layer alignment and positioning
• Perforation process
• Side glue application
• Longitudinal gluing and cylinder forming
• Precise reinforcement of the bag body structure
• Cutting using a die-cutting system

The final output is a semi-finished cylindrical tube product, which is automatically counted and stacked. The entire process operates continuously in a highly automated production line.

Key Features

The entire process is controlled via a PLC touchscreen Human Machine Interface (HMI). A high-precision servo control system ensures accurate, stable, and reliable speed regulation throughout production.

The machine is also equipped with:

• Automatic web tracking system
• Automatic color mark tracking system
• Automatic gluing system
• Automatic bag forming system
• Electro-optical material detection sensors
• Free length adjustment without gear replacement
• Cold cutting system

The overall system is designed to be easy to operate and quick to learn for operators.

Part 3: Three-Paper-One-Film Automatic Bag Gluing Machine

Application

This single-head square-bottom automatic bag sealing machine is designed for the production and processing of multi-layer kraft paper packaging bags and similar types of packaging paper materials.

Production Process Flow

Semi-finished cylindrical tube products are stacked on the automatic feeding table of the valve bag gluing machine. Through a conveyor system and automatic position correction, the bag bodies are precisely aligned before the top and bottom valve openings are formed and cut.

Stage 1

• Indentation forming process
• Opening of top and bottom valves
• Automatic robotic arm support operation
• Synchronized feeding of inner and outer valve materials
• Valve forming and cutting
• Material transfer to top and bottom valve positions

Stage 2

• Bag structure forming
• Folding opening process
• Gluing process

Stage 3

• Final forming process
• Structural compression and reinforcement
• Automatic counting
• Finished product output

Automation System

This production line is equipped with advanced electrical systems and mechanical components that enable seamless coordination between individual and group controls, resulting in a highly automated production process.

Key features include:

• Sealed through-shaft conveyor system
• Automatic lateral position adjustment based on bag length
• High-precision differential mechanism for accurate forming
• Photoelectric sensors for real-time monitoring of blank bag movement
• Touchscreen control panel for production parameter settings
• PLC system controlling all machine components with high precision

Servo motors are used in both the main unit and feeding system, while the entire machine is controlled via a PLC Human Machine Interface (HMI). This allows real-time operational data display and precise, stable speed control across the entire system.

Configuration Options

The machine is available in two models:

• Double-Head Automatic Square Bottom Bag Sealing Machine
• Single-Head Automatic Square Bottom Bag Sealing Machine

Advantages

✔ High level of automation
✔ Consistent production accuracy
✔ Easy operation via PLC touchscreen
✔ Flexible parameter adjustment
✔ Simple maintenance
✔ Requires only 2 operators to run the entire production process efficiently

Parameter

Section 4: Automatic Bottom Gluing Machine for Valve Bags (Drum Bags)

Application Purpose

Valve bags that have not yet had their bottom installed are placed on the automatic feeding platform of the valve bag bottom gluing machine (drum bag type). Through a series of processes such as material conveying, position alignment, adhesive application on the valve bottom film, installation of the upper valve and bottom paper layer, pressing on both upper and lower valve sections, and automatic counting, fully finished valve bags can be produced.

Key Features

The Automatic Bottom Gluing Machine for Valve Bags (Drum Bags) is a finishing equipment for final products of three-paper-one-film valve bags. The machine is equipped with advanced electrical systems and mechanical mechanisms, and supports combined control systems (single and group control linkage), ensuring high automation and stable production performance.
