Intermittent Motion

The following video shows the workflow of the intermittent motion 123 bottom box folding machine.


Referring to the photo below, you can understand the core components of this little carton erector.


It includes the following parts:

  • Box Blank Magazine

Pre-store box blanks, up to 400 pieces, depending on the blank thickness.


  • Pneumatic System

Grab the 123 bottom box blanks and then transport the blanks to the box-forming station.


  • Carton Forming Unit

Fold the two closure flaps and the female bottom closure panel.


  • Bottom Locking Unit

A pneumatically controlled tucker inserts the male bottom closure panel into the female bottom closure panel, and the flaps & panels interlock together to close the bottom.


  • Formed Carton Outlet

The formed box is pushed by the tucker to the outlet and dropped into the pre-placed collection cardboard box below.

  • Console

Control the erector operation, and set the corresponding parameters according to your production needs.

  • Electric Cabinet

It contains important components such as PLC, photoelectric eye, air cylinder, etc., which is equivalent to the brain of the erector.


  • Alarm Indicator

When this little carton erector is running abnormally, the alarm indicator will light up, reminding you to check and solve the problem.

  • Safety Cover

In the event of a machine accident, it protects the operator.



The operation of this small box folding machine includes the following steps:

  • Box Blank Pick Up and Transfer

Two vacuum suction cups suck a box blank from the blank magazine and then move the box blank to the box forming station.


The lead screw that holds the blank magazine is adjustable, and adjusting the lead screw can make the magazine fit your carton size.

  • Box Forming

After the box blank arrives at the carton forming station, it is detected by the photoelectric eye first, and the photoelectric eye feeds back a signal to the PLC.


Then, the PLC sends a command, the other two vacuum suction cups absorb the box blank and generate a reverse pulling force on the box blank, and the two reverse pulling forces erect the box blank into a square shape.

  • Bottom Interlocking

After erecting the box blank into a square shape, the bottom locking unit comes on stage.


The bottom locking unit folds the female bottom closure panel first, then folds the two closure flaps, and finally tucks the male bottom closure panel into the female bottom closure panel.


  • Output Erected Box

After completing the bottom interlocking, the tucker will push the erected box out of the bottom locking station, and the erected boxes with open tops drop into the pre-placed collection cardboard box.

Snap Lock Bottom Box Forming Machine Suppliers

Search keywords such as snap lock bottom box former and 1 2 3 bottom box former in the keyword Planner of Google Adwords, and their monthly search volume is 0-10 globally.

Such search volume can partially reflect that there are few potential customers searching for 1 2 3 bottom box forming machines.


Because of this, there are relatively few suppliers of such small case erectors.

Well-known case erector manufacturers in America, Combi, Lantech, Loveshaw, Pearson, Wexxar, etc., all specialize in corrugated box erectors but do not provide folding carton erectors, snap lock bottom box formers are unavailable from them.

Mailer Box Folding Machine

SiroSilo often encounters customers inquiring about pizza box folding machines.

For example, Ilkka, a Finnish customer sent us an inquiry on October 27, 2023.


His pizza box is very special, a gusset tuck box.


We sent him the following video and asked them to confirm whether his box was consistent with the one in the video.

In the Chinese market, almost all of the box former manufacturers you can find produce postal/mailer box folding machines or rigid box forming machines.


In other words, if you want to purchase a pizza box folding machine, you must discuss the customization with these manufacturers, they will assess the input-output ratio before taking orders.

Let us get back to business, we introduce to you in detail the mailer box folding machine (the mother machine for pizza box folding).


As shown in the photo below, the parts of the pizza box folding machine are clearly visible.


  • Lifting Motor
  • Transmission Chain
  • Box Blank Magazine

This mailer box folding machine has a compact structure, a small footprint, and a touchscreen HMI for one-button control.

Its operation is simple, and you can add box blanks without stopping the machine, reducing downtime.

Large Box Case Erector

SiroSilo not only supplies folding carton erectors, but also sells corrugated cardboard box erectors, including case erector tape, case erector glue, and box folding robots.

BOPP Adhesive Tape

Corrugated carton erectors with bopp tape bottom seals are the most common in the Chinese market, with numerous suppliers.

The pressure sensitive tape applicator sticks bopp tapes of different widths such as 72mm, 60mm, 48mm, and 45mm to the outer flaps (major flaps) of corrugated boxes, completing the bottom sealing.

Water Activated Tape

Water activated tape case erectors are extremely rare in the Chinese market.

Currently, its speed is only 2-4 CPM, which is a stumbling stone or brake that prevents many customers from making a purchase decision.

Hot Melt Glue

Hot melt adhesive sealing is becoming more and more popular because it has the following features.

  • Environmental Friendly

As a kind of non-toxic and odorless chemical product, hot melt glue is environmentally friendly and has been widely used abroad.

As China increases its environmental protection efforts, hot melt adhesive sealing has become increasingly popular.

  • Firm

Daily beer cartons are sealed with hot melt adhesive.

If you introduce tape to seal, the effect will be much worse.

  • Anti-theft

Tape is easy to peel off and reseal from the outside, but hot melt glue is not.

Tearing off the hot melt adhesive seal will destroy the entire carton and is unrecoverable.


The speed of the box folding robot is also slow, 4-8 CMP.

But it can erect cartons of different sizes in each run, just by pairing it with multiple box blank magazines.

This attractive feature has won the favor of many customers.
