Remarkably, the general working principle of a high speed case sealing machine is quite straightforward.

Here are the main aspects involved in the working process of this particular equipment;

Setting Empty Cases In Position

The cases move from the blank case zone through the feeding unit one by one.

Each case opens up at the right angles with the aid of a push plate and the guide rails that direct them to the correct position.

The machine, through a series of push and suction mechanisms, fold the cases to enable them to attain the right shape.

Loading

At the loading zone, the equipment loads the items into each case accordingly.

The loading techniques often vary depending on the actual type of high case sealing machine you are using.

Folding

Once the items are loaded into the cases, they are pushed to the folding zone through the conveyor system.

At this stage, the case flaps are folded through a continuous rotary motion.

Once the flaps are properly folded, the conveyor system then moves them to the sealing zone.

Sealing

At the sealing area, the machine applies the adhesive tape or hot melt sealing technique to ensure the cases are securely closed.

Ordinarily, the pushing plate activates a push on the tongue, allowing it to fasten a lock forming seal.

The equipment then inspects the cases before conveying them to the loading zone.

You can find this equipment in various types but often depending on how it applies the seals on the cases.

The notable ones you are likely to come across in different applications include the following;

High Speed Random Case Sealer

This high speed case sealer variant uses a system that can easily adjust its tape height to seal different case sizes on the fly.

Ordinarily, it features a design construction that enables it to offer top and bottom sealing capabilities at high speeds.

Every case getting into this equipment is determined in height and width; thus, it can easily position folding and sealing system automatically.

high speed random case sealer

This machine variant does not require a set up for continuous runs of different random size cases.

It is easy to operate, cost-effective, self-adjusting, durable, and ideal for packaging products in cases of different sizes simultaneously.

High Speed Uniform Case Sealer

This is a type of high speed case sealing machine variant that uses a fixed tape head suited for specific case sizes on the fly.

Primarily, it implies that the tape head in this machine often requires manual adjustment for every case size with a different height.

Simply put, unlike a random high speed case sealer, a uniform case sealer is designed only for sealing boxes with same height at every specific run.

Once you set this machine to specific case size, it folds the upper section flaps and seals the top and bottom sides of the case.

When you need

Therefore, it is mostly suitable when handling cases with similar height dimensions in large-scale production.

It is also fast, accurate, and reliable hence an ideal consideration for industrial applications.

Top And Bottom High Speed Case Sealer

This case sealer variant is known for its production efficiency, dependable service with less maintenance needs.

Ordinarily, it features flight lugs designed to push each case at corner to square it during transfer.

Its flap folders are contoured to fold the flaps gradually at the score line and close them smoothly without any flap overlap.

High speed case erector refers to a piece of automated equipment designed to open cases and place them in position awaiting good’s stacking and sealing.

The design enables it to reliably position the knockdowns for precise introduction into the equipment for filling and sealing.

This machine also ensures the bottom flaps of RSC and HSC cases are folded as sealed with hot melt adhesive.

Primarily, the main role of a case erector is to ensure cases are erected and glued constantly and appropriately at high speeds.

high speed case erector

It is quite adaptive, and it is designed to avoid repetitive and wasteful equipment refills, thus minimizing operator involvement at accelerated production rates.

On the other hand, high speed case sealer is primarily designed to pace already erected case feeds, fold flaps, apply adhesive and compression to seal cases tightly.

As such, the main difference between these packaging equipment lies in functional variables.

Case erector opens and glues case flaps at high speeds before moving them to case sealer.

Conversely, case sealer folds the flaps and seal them tightly also at high speed to guarantee safety of the products.
