3.2. Components and Functions

This image displays the overall structure of the YLZF-1000 machine, highlighting its compact design and integrated components for automated liquid packaging.

This diagram illustrates the main functional areas: 1. Cursor Sensing for stable and accurate positioning; 2. Touch Screen with PLC control for easy operation; 3. Roll Film Rod for strong and durable film support; and 4. Bag Puller with motor-controlled film pulling for smooth and accurate movement.

This image highlights five key aspects: 01 Customizable bag type (Side-seal, Back-seal, Four-side -seal), 02 Microcomputer (Touch screen for parameter adjustment), 03 Automation (Bag making, filling, sealing, cutting, counting, date printing), 04 Photoelectric (Sensing system for bag pattern integrity), and 05 Food Grade (SU304 stainless steel construction).

The machine is designed to package various pure liquids, including cow's milk, mixtures, red wine, table vinegar, mineral water, and beverages, provided they are free of particles.

4. Setup

4.1. Unpacking

Carefully remove the machine from its packaging. Inspect for any visible damage that may have occurred during transit. Retain all packaging materials until you have confirmed the machine is in working order.

4.2. Placement

Place the machine on a stable, level surface capable of supporting its weight (approximately 450kg). Ensure there is sufficient space around the machine for operation, maintenance, and ventilation. Avoid locations with excessive dust, humidity, or direct sunlight.

4.3. Power Connection

Connect the machine to a compatible power supply (110V-220V/50HZ-60HZ). Ensure the power outlet is properly grounded and can handle the machine's electrical requirements. Do not use extension cords unless absolutely necessary, and ensure they are rated for industrial use.

4.4. Film Roll Installation

Load the PE packing film roll onto the film rod. Ensure the film is correctly aligned and threaded through the machine's guides. The machine supports film rolls for both side-seal and rear-seal bag types. The width former determines the bag width, which is constant for a given former, while bag length is adjustable.

The image shows the touch screen interface for adjusting parameters and the width former, which shapes the film into the desired bag width. The popular width former size is 320mm, and extra formers can be ordered for different bag widths.

5. Operation

5.1. Control Panel Overview

The machine is operated via a touch screen control panel. This interface allows for easy adjustment of various parameters, including bag length, filling volume, and sealing temperature. Refer to the on-screen menus for specific settings.

5.2. Filling Material Preparation

Ensure the liquid to be filled is pure and free of particles. Connect the liquid supply hose to the machine's inlet. The machine's check-valve system prevents liquid backflow when the filling process pauses.

This image demonstrates the machine actively filling and sealing sachets, with two completed sachets shown alongside the operational unit.

5.3. Adjusting Bag Parameters

Using the touch screen, set the desired bag length (50-150mm) and filling volume (50-500ml). The machine's cursor positioning system ensures accurate cutting based on printed film patterns.

5.4. Sealing Mechanism

The machine utilizes pure copper blocks for both horizontal and vertical sealing, ensuring strong and consistent seals.

The horizontal sealing block, made of pure copper, creates a firm and aesthetically pleasing seal. Finished products can withstand significant pressure, up to 70 kilograms.

The vertical sealing mechanism also uses a pure copper block, known for its fast heating, uniform temperature distribution, and excellent heat conduction properties, preventing deformation during sealing.

5.5. Batch Coding

The machine offers options for applying production dates or batch numbers using either a ribbon coding system or a steel stamp mechanism.

This image displays close-ups of the ribbon coding system (top) and the steel stamp mechanism (bottom), both used for printing production information directly onto the packaging film.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your YLZF-1000 machine.

6.1. Cleaning

• Daily: Wipe down all external surfaces with a damp cloth. Clean any liquid spills immediately.
• Weekly: Disconnect power. Clean the filling nozzle and liquid pathways thoroughly. Inspect and clean the sealing jaws to remove any film residue.
• Monthly: Perform a deeper clean of all accessible internal components.

6.2. Inspection

• Regularly check all electrical connections for signs of wear or damage.
• Inspect moving parts for proper lubrication and adjust as needed.
• Examine the packing film path for any obstructions or misalignments.
• Verify the functionality of safety features and emergency stop buttons.
