Automatic Pyramid Tea Bag Packing Machine with Ultrasonic Sealing

Product Overview

This automatic pyramid tea bag packing machine is designed to produce three-dimensional triangular bags and conventional flat tea bags from roll-fed mesh packaging material. It is suitable for green tea, black tea, scented tea, herbal blends, coffee, and other dry granular or small-cut infusion materials.

The machine automatically completes material feeding, electronic weighing, bag forming, filling, ultrasonic sealing, cutting, counting, and finished-product conveying. The electronic weighing system portions the product before it enters the formed bag, while the ultrasonic sealing unit joins the mesh material without relying on a conventional heat-sealing structure. Both triangular and flat bag formats are confirmed in the supplied machine specification.

This machine is intended for tea factories, herbal infusion manufacturers, private-label packers, coffee processors, and companies producing premium visible-mesh tea bags. Its high-speed integrated process reduces repetitive manual handling and supports consistent filling and package formation.

Final suitability depends on the product’s particle size, fiber length, bulk density, moisture content, and flowability. Long leaves, oversized flower pieces, sticky materials, or very fine powders should be tested before the weighing configuration and bag dimensions are finalized.

Applications

This machine is suitable for dry tea leaves, small-cut herbs, flower pieces, coffee granules, and other infusion materials that can be measured by an electronic weighing system. Products should have suitable flowability and particle size for reliable feeding into flat or triangular mesh bags.

This machine is suitable for:

• Green tea
• Black tea
• Oolong tea
• Jasmine tea
• Scented tea blends
• White tea pieces
• Rooibos tea
• Peppermint tea
• Chamomile flower pieces
• Herbal infusion blends
• Fruit tea blends
• Roasted barley tea
• Small-cut botanical roots
• Coarse ground coffee
• Other dry infusion granules

A material test is recommended for products with long fibers, oversized leaves, excessive fine powder, high moisture content, irregular pieces, poor flowability, or a tendency to bridge inside the feeding and weighing system.

Main Features

1. Pyramid and Flat Bag Production

The same packaging unit can produce three-dimensional triangular tea bags or conventional flat bags, subject to the selected forming and packaging material configuration.

2. Electronic Weighing System

The product is measured by an electronic weighing system before filling, making the machine suitable for tea leaves, herbal particles, coffee, and similar granular materials.

3. Ultrasonic Sealing

The documented ultrasonic sealing system joins the mesh packaging material and forms a secure seal for triangular or flat infusion bags.

4. Fully Automatic Packaging Cycle

The machine automatically completes feeding, measuring, bag forming, filling, sealing, cutting, counting, and finished-product conveying in one continuous process.

5. High-Speed Production

The confirmed packaging speed is 70–100 bags per minute, depending on the product characteristics, filling weight, bag size, and weighing configuration.

6. Adjustable Bag Dimensions

Bag length can be adjusted from 45 to 90 mm, while bag width can be selected from 40 to 90 mm within the confirmed range.

7. Multiple Mesh Material Options

The machine supports nylon mesh, polyester mesh, nonwoven material, and corn-fiber packaging material as listed in the supplied specification.

8. Small-Dose Filling Range

The confirmed measuring range of 1–10 g covers many common tea, herbal infusion, and coarse coffee portions.

9. Finished-Product Conveying

After sealing and cutting, finished tea bags are transferred through the documented conveying section for collection or connection with downstream packaging equipment.

Working Principle

The product is first supplied to the upper feeding and electronic weighing system. The weighing unit measures the preset portion and releases it when the bag-forming section is ready.

Roll-fed mesh material is unwound and guided into the forming mechanism. Depending on the selected setup, the material is shaped into either a triangular pyramid bag or a flat tea bag. The measured product is discharged into the formed bag, after which the ultrasonic sealing system closes the package.

The cutting mechanism separates each finished tea bag, while the counting system records the completed output. Finished bags are then transferred through the discharge or conveying section for collection or connection with an outer bag packaging machine.

Product flowability, particle size, bag dimensions, and packaging material must be confirmed before final production settings are established.

Process Flow:

Material Feeding → Electronic Weighing → Mesh Film Feeding → Bag Forming → Filling → Ultrasonic Sealing → Cutting → Counting → Finished-Product Conveying

Machine Details

1. Upper Feeding System

The upper feeding section receives the tea, herbs, coffee, or granular infusion product and continuously supplies it to the electronic weighing units.

2. Electronic Weighing Unit

The weighing unit measures each product portion before discharge. Different weighing-head configurations are referenced in the supplied quotation and should be confirmed according to the material and required output.

3. Mesh Film Unwinding System

The roll-film section holds and feeds nylon, polyester mesh, nonwoven, or corn-fiber packaging material into the forming mechanism.

4. Pyramid Bag Forming Section

This section guides and shapes the mesh material into a three-dimensional triangular package. The machine can also produce flat bags when fitted with the corresponding setup.

5. Ultrasonic Sealing Unit

The ultrasonic system seals the mesh material after filling and creates the closed edges required for the finished triangular or flat tea bag.

6. Cutting Mechanism

After sealing, the cutting mechanism separates each finished package according to the selected bag length.

7. Control Interface

The machine image on page 2 shows a front-mounted operating interface used for machine operation and production-setting adjustment.

8. Finished-Product Conveyor

The completed bags are discharged and transferred away from the sealing area for collection or further packaging.

9. Mobile Machine Frame

The lower packaging unit shown on page 2 is fitted with caster wheels, supporting positioning and movement during installation, cleaning, or production-line adjustment.

Technical Parameters

Packaging & Shipping

The supplied quotation states that wooden-case packing, coding equipment, freight, and related shipping charges are not included in the listed machine prices. Therefore, the final packing method and shipping cost must be confirmed according to the selected weighing configuration and optional equipment.

Before shipment, the machine configuration, voltage, weighing-head quantity, bag former, ultrasonic sealing system, packaging material, and optional downstream equipment should be checked against the confirmed order.

The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration. A separate conveying hopper, outer bag machine, or premade pouch packaging unit may affect the number of wooden cases and total shipment volume.

Destination charges, customs clearance, import taxes, and local delivery arrangements should be confirmed separately with the buyer.
