The mechanism of valved bag filling machines are produced in various ways depending on the powder, bag weight, number of nozzles and other determining conditions, including the needs of the client. Turbine filling system is one of these methods; This system has a central propeller that rotates at a high speed (around 700 rpm). This device performs the filling operation by means of the centrifugal force of the propeller and with the help of the air pressure.

• Parts such as turbines and nozzles are modeled, and forging and welding methods are not used.

Velobag bags are produced in the form of envelopes and have only one open entrance from the corner to fill materials. The inner flap of the entrance of these bags acts as a one-way valve and closes automatically after filling. It is obvious that in order to use these bags, we need a filling machine for this type of bags.

 

It is obvious that in order to use these bags, we need a filling machine for this type of bags. First, the weighing bag model, such as turbine or gravity screw types; And in the second model, the bags are not placed on the weighing plate and the weighing is done in the separate part of the weighing hopper, and the final weight is entered into the bag by another mechanism such as (nozzle or auger). The good thing about weighing in a hopper is that you can achieve high accuracy in weighing and a weight error of about 20 grams.

 

According to the mechanism of driving the material towards the weighing hopper, the weighing hopper system itself is divided into two categories: Weighing hopper with screw system and weighing hopper with CUT GATE system

•  The ability to install screws to increase the capacity up to 120 bags per hour.

• The design of the body is completely laser cut and profile and forging methods are not used.

• Use of PLC, HMI and step motor system for better process control.

• Ability to support remote automation using the Internet.

• Bolt and nut assembly of the whole device: this feature causes parts of the device to wear out due to auger wear; With the services provided by the manufacturer, you can easily replace the wearable part without any welding or cutting operations, just by opening and closing a few bolts and nuts.

If you’re looking for a precise, automatic valve bag filler for powder production, you’ve come to the right place!

As you know, packaging various types of powders requires specialized filling machines due to the different properties of powders, such as particle size, stickiness, and the specific requirements for industrial, hygienic, and pharmaceutical grades. The machine before you offers extensive capabilities for packaging a range of powders, from construction and industrial materials to food and hygiene products.

The Powder Filler – CW1-A is designed and manufactured by our specialists at Ebra Machine. This automatic device features a suspension system and vibrator to ensure uniform filling into the bag while simultaneously preventing dust generation. This process is carried out exclusively by our experts at Ebra Machine.

The CW1.A machine is suitable for filling a variety of powders and granules.

This fully automatic device performs all stages of loading, weighing, injecting, and sealing the bag without manual intervention. In practice, the operator’s only task is to place the bags.

Furthermore, all machines manufactured by Ebra Machine, including the CW1.A, can be upgraded in design and construction after the initial design phase and before the pre-production stages. For instance, with a few adjustments, the production capacity can reach up to 3.5 tons per hour. The machine can also be converted from a three-phase to a single-phase configuration if needed.

In addition to its upgradeability, this machine can be connected to various conveyors, bag filters, and different types of bagging robots.

Advantages of CW1-A:

•  Very High Bag Weighing Accuracy: The machine offers exceptional precision in weighing bags.

•  Low Filler Error Rate: The error rate in filling is minimal.

• Installation Without Local Welding: It can be installed on-site without the need for welding.

• Maintenance-Friendly Design: Features inspection valves in various parts of the machine for easy maintenance and repair.

• No Dust Generation: Utilizes a non-air system for filling bags, thereby preventing dust creation

Disadvantages of CW1-A:

• Slower Filling Speed: The use of an auger mechanism for filling valve bags results in a slower filling speed compared to other powder filling models.
