What is a screw powder packing machine?
A screw powder packing machine is an automatic device that uses a screw dosing mechanism to pack fine powder materials with high precision. This type of machine is suitable for packing powders such as tapioca starch, instant coffee, turmeric powder, wheat flour, cocoa powder, milk powder, matcha, herbs, powdered medicine, cereals, chemicals... with weights from 1g, 10g, 20g, 50g, 100g, 200g, 500g to 1kg or more, depending on the specific requirements of the customer.
Because these powders are very fine and easy to create dust, accurate dosing by methods such as weighing scales or volumetric cups is often difficult and does not meet the requirements. In this case, the automatic packaging machine using a screw is the optimal solution thanks to its ability to accurately quantify and operate stably and continuously, suitable for fine powder products with dusty properties.
Features of the screw powder packaging machine
Some outstanding features of the powder packaging machine you should know:
- Regarding the electrical part of the screw powder packaging machine
- The screw powder packaging machine is controlled by PLC programming, ensuring stable and efficient operation.
- The servo stepper motor is used to pull the film, helping to set the bag length quickly and accurately.
- The inverter controls the main motor to help the machine operate smoothly and stably.
- The machine is also equipped with a sensor (magic eye) to accurately locate the cutting point according to the market mark on the film.
- The thermometer helps to adjust and set the temperature intuitively, suitable for many types of complex films.
- Regarding the mechanical part of the screw powder packaging machine
- The machine frame and mechanical parts such as rollers, cams, and measuring chutes are designed to be sturdy and undergo testing and inspection on modern design software such as Solidworks, Pro Engineer, Master Cam, etc. by professional engineers.
- The machine parts are clearly published with unified dimensions, making it easy to manufacture, replace, and calibrate when necessary.
- Production is carried out on a large scale instead of individually.
- The machine housing and parts in contact with the raw materials are made of stainless steel to meet safety standards.
- The parts are manufactured with minimal error, ensuring precise assembly and increased aesthetics.
- The chute is conveniently designed to change the guide film and packaging film, and has an integrated feature to attach an automatic date printer.
Operating principle of screw powder packaging machine
The screw powder packaging machine operates based on the movement of a screw rotating around the vertical axis, bringing raw materials from the hopper into the packaging part in a spiral shape. This mechanism helps ensure that the powder quantification process is carried out continuously and evenly.
What is special is the ability to change the amount of powder to be packaged very flexibly. Adjusting the number of rotations of the screw makes it easy to control the amount of powder distributed, thereby meeting different quantification needs accurately. This is suitable for production requirements from small quantities (such as 0.5g - 5g) to larger quantities (such as 5g - 20g or 200g - 1000g), creating flexibility for production units.
Thanks to this adjustment capability, the screw powder packaging machine can meet a variety of business needs, from small scale to large production, ensuring high efficiency and accuracy in the packaging process.
