Three-Head Corner Seal Labeling Machine

The YIXING three-head corner seal labeling machine is a custom build for 90° corner seal labels on boxes. Three labeling heads sit side by side over a stainless-steel conveyor cabinet, with a touchscreen and an inclined discharge chute. Seal positions and count, and with them the specs, are set per project.

Quick answers

The YIXING three-head corner seal labeling machine is a custom corner seal labeler from Dongguan Yixing Automation Equipment Co., Ltd., built to the customer's seal positions and count.
The brochure photo of the YIXING three-head corner seal labeling machine shows three labeling heads side by side over a stainless-steel conveyor cabinet, a touchscreen and an inclined discharge chute.
The YIXING three-head corner seal labeling machine has no standard specs; its related standard model is the automatic corner seal labeling machine.
The YIXING three-head corner seal labeling machine applies 90° corner seal labels and carries three labeling heads on one conveyor.
The YIXING three-head corner seal labeling machine is intended for boxes that need several seal labels.

Overview

The three-head corner seal labeling machine applies corner seal labels to boxes. The brochure photo shows a stainless-steel conveyor cabinet with three labeling heads side by side, a touchscreen and an inclined discharge chute at the end. The seal positions and the number of seals drive the configuration, so no standard specs are published and each machine is defined per project.

The corner labeling process follows YIXING's standard automatic corner seal labeling machine: products arrive one by one on the conveyor or straight from a cartoner, receive a label folded 90° around the corner, and the label is pressed down with a material chosen to suit its stiffness. That standard model can apply one, two, three or four seals (two on top, one top and one bottom, or two on the bottom), runs stand-alone or linked to a cartoner, comes in basic and standard versions, and is widely used in electronics and toys.

For reference, the standard model is rated at ±1 mm and 40–80 pcs/min for labels 6–50 mm long and wide; those figures belong to the standard machine, not this custom build. For a quote, provide box samples, a sketch of seal positions and count, label samples (so label stiffness and the pressing material can be judged), target output, and whether the machine must link to a cartoner.

How it works

1 Boxes travel on the conveyor into the labeling section
2 The three side-by-side labeling heads apply the corner seal labels according to the project layout
3 Sealed boxes leave over the inclined discharge chute

Key advantages

Three heads side by side

Three labeling heads sit side by side over the stainless-steel conveyor cabinet, for layouts with several seal positions.

90° corner seals

The label wraps over the box edge at 90° to form a corner seal.

Seal layout built to order

Top, bottom or top-and-bottom seals, and how many, are designed around the customer's box.

Inclined discharge chute

Sealed boxes exit over an inclined chute at the end of the conveyor.

Touchscreen

A touchscreen on the machine body is used for day-to-day operation.

Selection tips

One or two seals on regular boxes: start with the standard automatic corner seal labeling machine (basic or standard version, 40–80 pcs/min).
The standard model can already apply one to four seals, so whether three heads are needed depends on the seal layout and output; send samples and let the factory compare both options.
If the machine follows a cartoner, state the cartoner's outfeed direction, conveyor height and cycle rate so the connection can be planned.
Label stiffness affects the choice of pressing material, so send the labels you actually use.

FAQ

How many seals can the three-head corner seal labeler apply?

Seal positions and count are set per project. For reference, the standard automatic corner seal labeler can apply one, two, three or four seals; the three-head machine carries three heads side by side, and how they share the work is set in the design.

What is corner seal labeling?

A label is applied across the edge of a box and folded 90° to hold the flap closed. The standard model can place two top seals, one top and one bottom seal, or two bottom seals.

How fast and accurate is the three-head corner seal labeler?

No standard specs are listed for this machine. The standard automatic corner seal labeler is rated at ±1 mm (excluding product and label tolerances) and 40–80 pcs/min for labels 6–50 mm long and wide, which can guide selection; the custom machine's figures are confirmed in its design.

Can it connect to a cartoner?

The standard corner seal labeler runs stand-alone or linked to a cartoner. If the three-head machine must link up, provide the cartoner's outfeed arrangement and cycle rate so the factory can plan the connection.

Does the label material matter for corner seals?

Yes. The standard model selects different pressing materials according to label stiffness, so send the labels you will actually use.

What should I prepare for a custom corner seal quote?

Box samples, a sketch of seal positions and count, label samples and dimensions, target output, and whether the machine will run stand-alone or behind a cartoner.
