Valve bags has wide applications and can be used to pack construction materials, minerals, concrete, fertilizers, chemical materials, food powders, etc.
An excellent filling machine can significantly improve the quality and speed of packaging and avoid dust pollution.
Therefore, choosing a suitable valve bag packing machine becomes very important.
&#;1. What is the Valve Bag
There are two types of valve bags: inner valve port bags and outer valve port bags. About the inner valve port, when the filling material is finished, the material will be automatically squeezed from the inside to close the valve bag. About the outer valve port, when the filling material is finished, you need to fold the extended &#;tuck-in sleeve manually.&#;
&#;2. Open-mouth Bags vs. Valve Bags
In contrast to valve bags, the open-mouth bag is closed on three sides and entirely open at the top side. After filling, you must close bags with the sewing machine or heat sealer.
Open-mouth bags win in terms of price because the manufacturing cost of valve bags is much higher than open pouches. However, using the valve bag can effectively avoid material leakage into the environment and ensure a clean environment and workers&#; health.
At the same time, because using the valve bag can more effectively drain the air from the bag, thus filling more material, the bag&#;s shape is more regular, more beautiful, and more convenient for palletizing.
The open-mouth bag can fit most packaging equipment; while using valve pockets, it is necessary to match the valve pocket packaging machine.
&#;3. Applications of Valve Bags
We can easily find valve bags playing an essential role in many industries and can often see a variety of valve bags.
Construction Industry: we can use the valve bagging machine to fill construction materials such as cement, concrete, sand, gypsum, etc.
Food Industry: All solid food materials can be filled with an automatic valve bag packing machine, such as flour, sugar, cocoa powder, salt, cake powder, etc.
Mineral Industry: packaging barite, garnet, graphite, bentonite, and other mineral materials can also be packaged using the valve pack bagger.
Agriculture Industry: seeds, feed, fertilizer, and other materials can also be packaged using valve bagging equipment.
Chemical Industry: applied to some powder and granular materials in the chemical industry, can use valve pockets to packaging. For example, plastic granules, zinc oxide, and other materials.
&#;4. What is the Valve Bag Filling Machine
Valve bag fillers are automatic packaging equipment. It is designed for valve bags. The valve bag filling machine has the functions of filling, weighing, and sealing and can hand all types of solid materials such as granules, powders, and flakes.
Compared to traditional bagging scales, the most significant feature of the valve bagger is that its feeding port is an extended tube that goes deep inside the valve bags. In contrast, the feeding port of the regular packaging scale is a big circular hole that requires the bag to be placed over the discharge port.
Because of the unique filling method, the valve bag packer can minimize material spillage and dust emissions, ensuring a clean environment and worker health.
This packaging machine can meet the weight requirements of 10-50kg and handle 10 bags per minute. We can also customize the valve bag filling machine to meet specific material types and packaging needs.

4.2 Details of Valve Bag Filler
These are the details about the valve bag filler.
For example, the starter device at the filling port ensures that the bag and the feeding tube form an airtight space.
We have added a toggle switch on the side of the feeding port to make it easy for the operator to start the machine quickly.
In addition, the use of LCDs and imported load cells are constantly improving the ease of operation and stability of the valve pocket packaging equipment.
We have also added a roller conveyor belt to make it easy to move valve bags.
4.3 Components of Valve Bag Filler
A genuinely satisfying valve bag filling machine that meets the material and packaging needs of the customer. Therefore, we will customize the specific valve bag filler.
Besides, some core components are the same.
Feeding Mechanism
For different materials, we will use different feeding methods. For example, impeller, anger, gravity, air, etc.
Feeding Spout
The filling spout is an important part equipped outside the machine. Put the spout into the valve bag, and the material will flow into the bag along the spout.
Weighing System
The core component is the load cell. It controls the feeding timing, detects the feed material&#;s weight, and ensures that the quantity is the same in all valve pockets.
Control System
The control system allows the operator to control the machine entirely. It can also send and receive electrical signals to give the corresponding feedback.
Bag Clamping Device
It will hold the bag and the feed spout firmly together, forming a closed space to minimize material leakage.
Bag Chairs
Bag Chairs are mainly used to support the valve bag during the filling process, so moving valve bags will be quicker.
Storage Hopper
The hopper is used to store the material.
Bag Loading Device (fully automatic option)
Suppose you choose the fully automatic valve bag filling machine. In that case, this device will automatically load the bag over the filling spout without manual involvement, providing a high-level automatic operation.
&#;5. Types of the Valve Bag Filling Machine
There are many different types of materials that need to be handled. Many clients also have many different requirements for packaging.
We build many different types of valve bag fillers to meet all their requirements and provide them with suitable valve bag filling equipment.
They can be distinguished in two directions.
- Classification according to the material types
- Classification according to the level of automation
According to the MATERIAL TYPES:
5.1 Impeller Filler
Inside the machine, the material is fed into the valve bag by rotating a multi-bladed vertical or horizontal impeller. This feeding method is suitable for smaller, drier powder materials.
The impeller filler allows for a faster filling process and avoids material leakage.
5.2 Gravity Filler
It is a simple filling structure. It relies on the gravity of the material itself to complete the filling process. It is often used for large materials that can flow freely, such as flakes, granules, or lumps. They can quickly be dropped from the hopper.

5.3 Auger Filler
It uses the horizontal auger to fill the material from the hopper into the valve bag. This feeding method is suitable for some dry bulk materials, powders, granules, flakes, and other materials.
When the auger rotates and feeds, little air is added to the product, thus reducing the risk of bag bursting during the filling process.
However, it should be noted that, generally, the auger filler is slower than other types.
5.4 Air Filler
Sometimes it is also named a forced flow or pneumatic packer. It uses pressurized air to push the material into the bag. It is very versatile, capable of filling all types of materials, and ensures fast filling speeds and filling accuracy.
Because of no moving parts, there is no need to worry about the wear and tear of the parts. However, be aware that excessive air may cause the bag to burst.
5.5 Vacuum Filler
We equip the vacuum valve filler with a vacuum chamber. By placing the bag in the vacuum chamber and using the air pressure difference, the material can be effectively sucked into the valve bag.
Usually, this feeding method is only suitable for lighter ultra-fine powder materials, such as carbon black, graphite, etc. And it has high accuracy.
According to the AUTOMATION LEVEL:
5.6 Semi-automatic Valve Bag Filling Machine
The semi-automatic valve bag filling machine needs the operator to load the bags and start the machine manually.
A start-up device is equipped on the side of the spout and can be touched easily. Starting the machine is safer and more efficient than using a sensor, which risks failing.
In addition, if your output requirements are not high, we can help you reduce the cost of the machine as much as possible while maintaining quality so that our customers can get the most suitable valve type bag filling machine at a cheap price.
5.7 Fully Automatic Valve Bag Filling Machine
The fully automatic valve bag packing machine achieves complete automation, and the filling process does not require manual participation.
The robot can automatically complete the tasks of bagging, filling, sealing, and conveying and can operate stably for 24 hours with high production efficiency.
Whether semi-automatic or fully automatic packaging machines, they are highly expandable. You can easily add auxiliary bagging equipment to them or add them to other packaging lines. It all depends on your needs.
&#;6. How Valve Bag Filling Machines Work
Initially, you should load an empty valve bag over the filling spout and activate the filling switch. The bag clamping mechanism will hold the bag. Then the feeding mechanism will start working while the weighing system continuously monitors the bag weight.
After the bag weight reaches the preset value, the clamping mechanism will release the bag. The bag will fall on the conveyor, which is the filling process.
Finally, depending on the type of valve bag selected, different sealing equipment is optional.
6.1 Selection of Bag Closing Machine for Valve Bags
Choosing different types of valve bags requires different bag closing equipment.
If you use bags with the inner valve opening, you do not need to use a bag sealing machine.
If you use bags with the external valve opening, you must use a bag sealing machine.
We offer two types of bag sealing: heat sealing and ultrasonic bag sealing
A heat sealer is heating the bag material, making it melt and condensing it when it cools.
An ultrasonic sealing machine is a kind of ultrasonic plastic welding machine which uses the ultrasonic concentrator to act on the sealing part of the packaging container. We usually install it outside the valve bagger to achieve automatic bag sealing.
&#;7. Benefits of Valve Bag Filling Machine
We need to understand that the many points of the valve bag filling machine make it more and more popular in the market.
- Offers a wide range of options for automation levels, making it easy for employees to operate.
