Hey there! As a supplier of Flexo Folder Gluers, I'm super stoked to break down the main components of these awesome machines with you. Flexo Folder Gluers are like the Swiss Army knives of the packaging world, handling everything from folding to gluing cardboard boxes with ease. So, let's dive right in and take a closer look at what makes these machines tick.
Feeder Unit
The feeder unit is where the magic starts. It's like the doorman of the Flexo Folder Gluer, welcoming in the cardboard sheets one by one. This part of the machine is responsible for picking up the cardboard from a stack and feeding it into the printing and folding sections.
There are different types of feeders, but the most common ones use suction cups or friction belts to grab the sheets. Suction cup feeders are great because they can handle a wide range of cardboard thicknesses and sizes. They work by creating a vacuum that sticks to the top sheet of the stack, lifting it up and moving it forward. Friction belt feeders, on the other hand, use the friction between the belts and the cardboard to pull the sheets through.
The feeder unit also has sensors to make sure that only one sheet is fed at a time. If there's a double feed or a misfeed, the machine will stop automatically to prevent jams and damage. This helps to keep the production process running smoothly and efficiently.
Printing Unit
Once the cardboard sheets are in the machine, they head to the printing unit. This is where the designs and labels are printed onto the boxes. The printing unit uses flexographic printing technology, which is a popular method for printing on flexible materials like cardboard.
Flexographic printing works by using a flexible printing plate that is wrapped around a cylinder. The plate has the design or text engraved on it, and ink is applied to the plate using an anilox roller. The anilox roller has tiny cells that hold the ink and transfer it to the plate. When the plate comes into contact with the cardboard, the ink is transferred onto the surface, creating the printed image.
The printing unit can have multiple colors, allowing for more complex and eye-catching designs. It also has controls for adjusting the ink density, registration, and other printing parameters to ensure high-quality prints.
Pre-folding Unit
After printing, the cardboard sheets move on to the pre-folding unit. This is an important step in the process because it prepares the sheets for the final folding and gluing. The pre-folding unit creates score lines and creases in the cardboard, making it easier to fold the boxes into the desired shape.
The score lines are made by pressing a sharp blade into the cardboard, creating a weak point that the sheet can be folded along. The creases are made by using a pair of rollers that squeeze the cardboard, creating a permanent bend. The pre-folding unit can be adjusted to create different types of score lines and creases, depending on the design of the box.
You can learn more about the pre-folding process in a Flexo Folder Gluer by checking out this Folder Gluer Machine Pre-folding page. It has some really useful information on how this part of the machine works.
Folding Unit
Once the sheets are pre-folded, they enter the folding unit. This is where the real action happens, as the sheets are folded into the final shape of the box. The folding unit uses a series of rollers, belts, and guides to bend the cardboard along the score lines and creases created in the pre-folding unit.
There are different types of folding units, depending on the complexity of the box design. Some folding units can handle simple straight-line folds, while others can do more complex folds like multi-panel boxes and boxes with flaps. The folding unit also has controls for adjusting the folding speed, pressure, and alignment to ensure accurate and consistent folds.
Gluing Unit
After folding, the next step is gluing. The gluing unit applies adhesive to the appropriate areas of the box to hold the folds together. There are different types of adhesives that can be used, depending on the type of cardboard and the requirements of the box.
The most common type of adhesive used in Flexo Folder Gluers is water-based glue. It's easy to apply, dries quickly, and is environmentally friendly. The gluing unit has a glue tank that holds the adhesive, and a pump that transfers the glue to the application nozzles. The nozzles spray the glue onto the cardboard in a precise pattern, ensuring that the box is glued together securely.
The gluing unit also has controls for adjusting the glue flow rate, pressure, and pattern to ensure the right amount of glue is applied. This helps to prevent over-gluing or under-gluing, which can affect the quality and strength of the box.
Delivery Unit
Once the boxes are folded and glued, they exit the machine through the delivery unit. The delivery unit is responsible for stacking the finished boxes neatly and transferring them to the next stage of the production process, such as packaging or shipping.
The delivery unit uses a conveyor belt to move the boxes out of the machine. It also has sensors to detect the size and position of the boxes, allowing it to stack them correctly. Some delivery units can stack the boxes in different configurations, depending on the customer's requirements.
Control System
Last but not least, every Flexo Folder Gluer has a control system that manages and monitors the entire operation of the machine. The control system is like the brain of the machine, allowing operators to set the parameters, adjust the settings, and troubleshoot any issues.
The control system is usually a computerized interface that displays all the important information about the machine, such as the production speed, temperature, and error messages. It also has buttons and switches for starting, stopping, and adjusting the machine.
Modern Flexo Folder Gluers often come with advanced control systems that use touchscreens and software to make the operation more user-friendly. These systems can also store different job settings, allowing operators to quickly switch between different box designs without having to reconfigure the machine every time.
