In addition, we install several photoelectric eyes on our SiroSilo carton erector machine.

These eyes monitor the actions of various parts, such as detecting the carton status & carton miss, ensuring carton forming is smooth.


Speaking of the carton forming, it includes the following steps:

  • Carton Blank Pickup
  • Bottom Dust Flap Folding
  • Bottom Closing Panel Folding
  • Bottom Tuck Flap Insertion
  • Finished Carton Outputting

Refer to the video below, let me explain our SiroSilo tuck end box erector machine’s workflow for you.

The vacuum sucker picks up the carton blank from the magazine, pre-breaks the blank into shape, then places it between two lugs on the drive chain.


The chain drives the carton forward, the plows fold two dust flaps first, then fold the bottom closure panel.

Finally, the air-controlled tucker inserts the bottom tuck flap to the carton, a fully-erected & bottom-sealed carton catches your eyes.


Then, the fully-erected & bottom-sealed carton moves forward to the outlet, directly into the downstream packaging equipment or into the pre-placed collection box below.


The tuck end carton erector machine just follows these processes, repeats them over and over again.

Snap Lock Bottom Carton Erecting Machine

With regard to the snap lock bottom carton erecting machine, it converts carton blanks to 1-2-3 bottom boxes.


When the formed snap lock bottom box comes out from the erector, its top closure panel & dust flaps are open for product filling.


As shown below:



SiroSilo 1-2-3 bottom box erecting machine consists of the following parts:

  • Control Console
  • Electric Cabinet
  • Alarm Light
  • Carton Blank Magazine
  • Carton Erecting Unit
  • Bottom Locking Unit
  • Carton Outlet

Turn on the power button on the control console, click “Start” on the touch screen to run the machine.

Two vacuum suction cups suck a carton blank from the magazine, they absorb the bottom of the carton blank, move to the carton forming station.


During the carton blank’s natural falling process in the magazine, the falling contact area & friction force is small.

With the block-shaped strip guiding carton blank falling, the falling process is smoother.

By adjusting the feed rod & lead screw of the carton blank magazine, you can change the magazine’s length & width, thus the magazine can fit different carton sizes.



After the carton blank arrives at the carton forming station, the photoelectric eye detects the carton blank, feeds a signal to the PLC.


The PLC sends commands, two vacuum suction cups absorb the upper part of the carton, apply an upward pulling force to the carton.

Two reverse pulling forces (upper & lower) erect the carton.


After erecting & shaping the carton, the next step is to lock its bottom, the bottom locking unit undertakes this task.

The bottom locking unit folds the top flap first, then folds the side flaps.

Finally, the tucker inserts the bottom flap into the top flap.


Snap Lock Bottom Box

With reference to the video below, you can clearly understand our SiroSilo tab lock mailer box erector’s entire workflow.

Four vacuum suction cups suck a carton blank from the magazine, moves to the top of the pressing & forming station.

When the pressing & forming station’s two baffles are in place, two plows fall down to form a pocket for box loading.

At this time, the pressing plate appears from the top of the carton blank, it presses the carton blank down.

The mailer box’s side panel, front panel, and rear panel are erected normally, its side panel’s closure flaps are also folded.


Then, the pocket carries the erected box to the next station.

In this follow-up station, a tucker folds inward the side closure panel, until the side closure panel adheres to the side panel, and inserts the side closure panel’s tabs into the bottom panel’s socket.
