Machine description

The automatic hot stamping machine of roll materials usually needs to carry out continuous hot foil stamping on the whole roll according to a certain pitch. This kind of automatic hot stamping machine is much more complicated than the hot foil stamping machine conveyed by single paper. The most important thing to solve the hot stamping of roll materials is Conveying and positioning problems of roll material. For the roll material without any printing, the adjustment of the conveying length of the roll material, the axial and radial positioning, and the control of the surface tension are all problems that need to be solved. It has already been solved on the machine, and it is enough to transfer these technologies to the hot stamping machine. In addition, for the printed roll materials, it is very important to ensure that the hot foil stamping position and the printing position are relatively fixed. This is the photoelectric control technology, photoelectric The switch can identify the printing color, and control the servo motor to drive the package material to the designated position for bronzing.
The automatic hot stamping machine for roll materials integrates various technologies such as automatic hot foil stamping technology, deviation correction technology, tension control technology, and infrared tracking technology. It represents the highest level of hot stamping technology and occupies an unattainable position in the field of plastic and paper packaging.

Machine structure

The structure of the roll-to-roll automatic hot foil stamping machine:

Unwinding mechanism

It is a device for placing the roll material to be hot stamped, which is composed of unwinding bracket, unwinding motor, tension control system, etc.

Hot foil stamping mechanism

It includes hot stamping plate, heating device, pressure applying device, etc. The hot stamping plate is engraved with the pattern or text to be hot stamped.

Rewinding mechanism

It is a device for collecting the hot stamped material, which is similar to the unwinding mechanism and is composed of rewinding bracket, rewinding motor, tension control system, etc.

Transmission mechanism

It is composed of motor, reducer, gear, chain or belt, etc. It transmits power to each component to ensure the coordinated and synchronous movement between the components.

Control system

Usually, control chips such as PLC (programmable logic controller) or single-chip microcomputer are used, in conjunction with touch screen or control panel, to achieve precise control of parameters such as temperature, pressure, speed, tension, etc. of the hot foil stamping machine, and can also monitor the operating status of the equipment and alarm for faults.

Tension control mechanism

It is composed of tension sensor, controller and actuator. The tension sensor detects the tension of the material strip in real time, transmits the signal to the controller, and controls the constant tension.

Correction mechanism

Common types include photoelectric correction and mechanical correction. The photoelectric correction mechanism detects the position of the edge or pattern of the material strip through a photoelectric sensor. When the material strip is offset, the controller drives the correction device to adjust the position of the material strip. Mechanical correction usually uses mechanical devices, such as guide rollers, screw nut mechanisms, etc., to adjust the position of the material strip to ensure that the material strip maintains the correct position during operation and avoids the deviation of the hot stamping position.

Hot stamping foil transmission mechanism

It includes an electroplated aluminum unwinding device, a guide roller, a tension adjustment device, and an electroplated aluminum winding device.

Machine advantage

The roll-to-roll automatic hot stamping equipment is an automated device for continuous hot foil stamping of roll materials such as paper, film, leather, and fabric. Its main features are as follows:

1. Continuous Conveying and Positioning

It is equipped with a roll unwinding and rewinding mechanism, a high-precision tension control system (such as a magnetic powder brake and servo motor), and a photoelectric web-correction device for precise control of roll conveying and positioning, ensuring accurate alignment of the hot foil stamping pattern with the substrate.

2. Diverse Hot foil Stamping Processes

It is compatible with hot stamping foils of various specifications, such as metallic foil, pigmented foil, holographic foil, and laser foil, meeting diverse decorative effects such as glossy gold, matte, laser, and colored. It can process roll materials of various materials, including paper, plastic film (such as PET and PP), leather, textiles, and metal foil. Adjustable hot stamping temperature, pressure, and speed allow for flexible adjustments to suit different hot stamping processes.

3. Automatic Control Linkage

The integrated PLC control system features a human-machine interface for convenient parameter setting, status monitoring, and fault notifications. It can be integrated into the production line and coordinated with other upstream and downstream equipment, including printing presses, die-cutters, and slitter machines, to form an integrated production process.

4. High-Precision Hot foil Stamping

The system utilizes high-precision hot stamping rollers or plates (such as copper or silicone plates) coupled with a precise servo drive system to ensure repeatable pattern positioning accuracy. High-end models can integrate multiple hot stamping units and, combined with an automatic photoelectric tracking system, enable multi-color hot stamping or overprinting, enhancing the layering and decorative effects of the pattern.

5. Detection

Broken material/foil detection automatically stops and issues an alarm if the substrate or foil breaks. The machine then automatically rewinds the waste foil after hot stamping, maintaining a clean production environment. Safety features such as protective covers and emergency stop buttons prevent operator contact with hot or moving parts, ensuring safe production.
