Filling into the packaging container of various products, there must be specifications and weight requirements, we in order to ensure that the amount of filler equipment called metering device, he has counting, capacity and weighing, today to explain to you is the measurement of the device in the auger filler, which can be a component of the filling machine, can also be independently made into a weighing facility, and a variety of packaging equipment supporting the use of, so as to achieve accurate What is an auger filler?
What is an auger filler?
The auger filler is a dosing device, often used for powdered materials, which is fed and dosed by a screw. The auger filler generally consists of 1 auger sleeve, 2 handwheels, 3 augers, 4 agitator paddles, 5 shafts, 6 agitator sleeves, 7 hoppers, 8 agitator gears, 9 discharge motors, 10 agitator motor (corresponding to the number on the picture). The metering device is driven by an AC servo motor (Fig. 9) to rotate the shaft 5 and screw 3, while the stirring motor drives gear 8, the stirring sleeve, and the stirring paddle to rotate so that the material filled into the screw is more uniform.
Parts of an auger filler
Hopper
This is a container hopper, which is of a monolithic construction. Inside the hopper, the powdered product is stored, and precise dosing is achieved by controlling the speed of the screw by means of the volumetric principle of the screw.
Drive assembly
The drive assembly of the auger filler is composed of 2 motors. As you can see in the picture above, there are 2 motors for 9 and 10 parts, one is to control the feeding and the other is to control the mixing. Different motors provide different work, which will lead to higher accuracy and more efficient and stable completion of the work.
Secondly, the AC servo motor driven screw metering device will improve the accuracy and reduce the noise than the stepping motor. Of course, servo motors are more expensive than stepper motors.
Tooling: Auger + Agitator Blade + Funnel
The internal intermediate components include a screw, an Agitator Blade, and a Funnel.
Auger
As the main precision component, the screw is the most important. Each screw has a theoretical volume, and the speed of the screw is controlled during each charging cycle so that accurate metering can be obtained.
It is made of high-strength, heat- and corrosion-resistant alloy steel, and is designed to push the plastic forward, causing it to melt by generating pressure and agitation while rotating and generating frictional heat with the plastic.
Agitator Blade
The purpose of the Agitator Blade is to make the material in the hopper more homogeneous and to prevent agglomeration. This design directly affects the mixing result of the material and ensures the homogeneity of the material, avoiding problems due to uneven mixing. The rotary motion of the mixing paddle generates shearing force and kneading effect, which makes the material undergo complex movement in the mixing drum, thus promoting the mixing and dispersion of different components. This shearing and kneading effect helps to speed up the mixing process and improve the mixing efficiency.
Funnel
The logistic characteristics such as fluidity and adhesion of different powders vary widely, and funnels are interfaced with packaging containers. The funnel can be equipped with different styles of nozzles according to the user’s needs. The right nozzle can avoid the problem of powder leakage or difficult or clogging of the material, and thus improve the filling accuracy.
Container Filling
Down the funnel is the volumetric filling, which can be selected for bags, cans, and bottles, and of course is followed by other fully automated packaging machines to realize different packaging methods.
Control Panel
Generally speaking, the operation of the auger filler can be controlled by a control panel or a foot pedal, Semi automatic auger filling machine can be controlled by a foot pedal to control the time of discharging, which combined with the manual control, can reduce the cost. The control panel is usually fully automatic to control the dosing and discharging, and is more in pursuit of automated programs.
Auger filling machine working principle
The working principle of the Auger Filling Machine is based on the “Quantitative Powder Packaging” technology, which is divided into three parts: Feeding System, Weighing System, Sealing System and Control System.
The feeding system takes the powder out of the raw material bin and transports it through the conveyor to the weighing system. This system consists of automatic lifters, vibrators, conveyors, etc. to ensure that the powder flows evenly into the weighing system.
The core of the weighing system is realized by the rotation of the screw and the real-time monitoring of the metering sensor. When the predetermined weight reaches the set value, the control system will automatically close the screw and complete the metering to accurately measure the quantity of powder required for each bag to ensure the stable and consistent quality of each bag of powder.
The sealing system mainly consists of fixture and sealer. When the bag filled with powder is transferred through the fixture, it will automatically be in the right position, and then the bag is fixed on the sealer, which effectively seals the bag through thermal pressure to avoid powder leakage.
The control system monitors the operating status of the equipment and controls each part. For example, when the hopper capacity exceeds a certain capacity, a signal is sent to the control system, which automatically stops the feeding system or gives an alarm indication.
Types of the Auger Filling Machine
1. Semi-Automatic Auger Filler
Semi-automatic auger filling requires manual intervention, as you can see from the video, the auger is metered by the screw and then fed into the container under manual control. This machine is very maneuverable and can be used to change the form of the container at any time, allowing for a wide variety of packaging methods.
2.Automatic auger filling machine
Fully automatic auger filling machine with higher automation program. The auger can be combined with a horizontal bagging machine, a vertical bagging machine and a filling system to realize a wide range of packaging methods, without the need for constant human intervention.
3.Fill-By-Weight Auger Filler
Fill-By-Weight Auger Fillers are used if you need to package powder or granular products with high precision weight control, as they are fed in real time by electronic scales or weight sensors to ensure that the weight of each package is consistent.
4.Net Weight Auger Filler
If your product requires a high degree of accuracy in net weight labeling, such as in the pharmaceutical field, food weight bagging or filling, the Net Weight Auger Filler is the perfect solution for you. This type of Net Weight Auger Filler emphasizes the control of the net weight of the final package, which, like the Fill-By-Weight Auger Filler, uses a weight sensor to control the filling process, but then removes the weight of the packaging material itself from the calculation, and only the net weight of the material inside the package is accurately measured.
5.Multiple Auger Fillers
Multiple Auger Fillers are a good choice if your product requires mixed ingredient product packaging, such as breakfast cereals, pet food, premixes, etc., where several ingredients need to be filled in specific proportions. It is more than one screw, and multiple screws can fill multiple materials or different amounts of materials simultaneously or sequentially. This design improves production flexibility by allowing precise proportioning of multiple ingredients within the same package, as well as the ability to quickly switch between different product specifications using multiple production lines.
In summary, each of these five types of screw discharging equipment demonstrates its own advantages in terms of precise weight control, net weight metering control and multi-ingredient mixing and packaging to meet the specific packaging needs of different industries and products.
The uses of auger filling machines
If you are a powder manufacturer, you may have come across different forms of packaging that can be realized with different core packaging machines.
An example:
When your determine the packaging powder bag is stand up shape, then you may choose a prefabricated bag feeder with screw down device, because you only need to complete the down and sealing on the finished product output.
When your bags are pillow bags, designed roll film, this time a vertical packaging machine will solve your bag forming, feeding, sealing all-in-one fully automatic packaging machine. And screw metering in this type of machine is the most widely used, common is the packaging of flour, seasoning packaging, coffee powder packaging, chemical product packaging and so on.
If you pack the form of cans or glass jars, then it is necessary to match the filling system, filling equipment also includes a can sealing machine to seal the cans.
However, these packaging powder site can not be avoided is the increase in dust, so it is generally recommended that customers in the various machines to increase the collection of dust sealing device, in order to achieve an effective reduction of dust.
There is also a special case to flour example, the use of straight down the screw will be faster, so that straight down the screw directly to the bottom of the filling, from the root to reduce the dust, but this is only suitable for the use of vertical packaging machine cases to come.
