Embossment Hydraulic hot stamping machine

    The fluid is incompressible, so it can be used as the transmission medium of the power of the hydraulic stamping machine. Compared with the pneumatic stamping machine, its pressure is higher and more stable. The hydraulic bronzing machine has a wide range of applications in concave and convex bronzing, die cutting, large flat bronzing and bronzing on hard plastics. The hydraulic hot stamping machine supplies the liquid through the hydraulic pump, and the liquid transmits the action to the hydraulic valve and the hydraulic cylinder through the operation command to perform the hot stamping. Due to the huge pressure of the hydraulic bronzing machine, the materials for making the bronzing machine, such as hot stamping, and the workbench all require high-strength steel.

Structural composition

1. Body and frame:

• High-strength high-quality steel is used for precision processing to ensure that the structure has strong rigidity and stability, can withstand the high pressure applied by the hydraulic system, and will not easily deform during long-term hot stamping operations, laying a solid foundation for achieving high-precision hot stamping.

2. Hydraulic system:

• Hydraulic pump: As the power core of the entire hydraulic system, it can extract hydraulic oil from the oil tank and accurately output hydraulic oil of different pressure levels according to the actual hot stamping needs. For substrates with different thicknesses and materials such as book color box packaging, the pressure can be flexibly adjusted to ensure the hot stamping effect.

• Hydraulic cylinder: connected to the hot stamping component, the internal piston is pushed by the pressure of the hydraulic oil, thereby generating a stable and strong pressure, so that the hot stamping plate and the substrates such as book color boxes fit closely. Its stroke can be adjusted as needed to adapt to different stroke requirements under various hot stamping processes, such as the stroke changes corresponding to different depths of concave and convex patterns during concave and convex three-dimensional hot stamping.

• Hydraulic valve and oil pipe: Hydraulic valve plays a key role in accurately controlling the flow direction and pressure of hydraulic oil. By reasonably controlling the opening and closing of the valve, it ensures that all links of the hydraulic system operate in an orderly manner according to the preset. The oil pipe is responsible for safely and stably transmitting hydraulic oil between various hydraulic components, and has good sealing to prevent problems such as hydraulic oil leakage from affecting the normal operation of the system.

3. Hot stamping system:

• Hot stamping head: The hot stamping head of the hot stamping machine is usually made of high-strength steel with good heat conductivity, which is used to install the hot stamping plate. The hot stamping plate is made using high-precision engraving, etching and mold forming processes. For the concave and convex three-dimensional hot stamping of book color box packaging, it is necessary not only to finely present conventional elements such as patterns and texts, but also to accurately shape the shape and depth of the concave and convex parts, so that the hot stamping can show a realistic and three-dimensional effect, and enhance the beauty and texture of the packaging.

• Heating device: Generally, electric heating is used, which has the ability to quickly heat up and stably control temperature. The temperature can be precisely adjusted according to different types of electroplated aluminum foil and the materials of book color boxes (such as paper, cardboard, etc.), ensuring that under appropriate temperature conditions, the electroplated aluminum foil can smoothly transfer the corresponding metal layer and pigment layer to the substrate to achieve high-quality hot stamping.

4. Control system:
• Using the common relay operation panel as the control unit, the operator can easily set the hydraulic stamping time, the temperature of the heating device, and the hot stamping time, the pressure parameters corresponding to the concave and convex parts during the concave and convex three-dimensional hot stamping, etc.

5. Auxiliary device:

• Waste collection device: used to collect electroplated aluminum foil waste generated during the hot stamping process, keep the equipment and working environment clean, and avoid waste from adversely affecting the operation of the equipment and the quality of hot stamping.

Working principle

First, place the book color box that needs hot stamping on the conveyor belt of the substrate conveying and positioning system. After accurately fixing its position with the positioning fixture, the conveyor belt smoothly transports the book color box to the hot stamping station at the set speed. Install the concave and convex hot stamping mold, start the heating device to heat the temperature to the preset temperature. Start the hydraulic system, the hydraulic pump delivers hydraulic oil to the hydraulic cylinder, and the hydraulic cylinder pushes the hot stamping plate down towards the book box, so that the hot stamping plate and the book box fit tightly. In the case of concave and convex three-dimensional hot stamping, according to the design requirements of the concave and convex pattern, the hydraulic system applies appropriate pressure, so that the electrochemical aluminum foil transfers the corresponding metal layer and pigment layer to the book box according to the pattern and concave and convex shape of the hot stamping plate under the dual effects of temperature and pressure, thereby forming a hot stamping pattern with a concave and convex three-dimensional effect. After the hot stamping is completed, the hydraulic system controls the hot stamping plate to rise and reset, and the conveyor belt then sends the hot stamped book box out of the hot stamping station.

Features and advantages

1. Excellent hot stamping effect: With the stable and strong pressure provided by the hydraulic system, combined with high-precision hot stamping plates and precise temperature control, a clear, exquisite and three-dimensional hot stamping pattern can be presented on the book box packaging, which greatly enhances the visual appeal of the packaging and the product grade, and helps the product stand out in the market.

2. Wide application range: It can well adapt to the hot stamping needs of book color box packaging of different materials (paper, cardboard, cardboard, etc.), different thicknesses and various sizes. It only needs to properly adjust the parameters such as hydraulic pressure, heating temperature, hot stamping time according to the specific characteristics of the substrate to achieve high-quality hot stamping effect, and it has strong versatility.

3. High precision control: From the precise positioning of the substrate to the precise setting of the parameters of the hydraulic system and hot stamping system, each link cooperates with each other to ensure the position accuracy of the hot stamping pattern on the book color box and the consistency of the concave and convex three-dimensional effect, effectively avoiding quality problems such as pattern offset and uneven depth, and meeting the production scenarios with high requirements for packaging and printing quality.

4. Convenient and flexible operation: Through the relay operation panel, the operator can easily set and adjust many parameters of the equipment without complex operating skills and professional knowledge, and can quickly switch the hot stamping programs corresponding to different book color box products, which is convenient for responding to diversified production orders and improving production efficiency.

5. Both production efficiency and stability: The overall structure of the equipment is reasonable, the coordination between the various systems is stable and reliable, and it can run continuously for a long time. While ensuring efficient production, it reduces production interruptions caused by equipment failures. For mass production of book color box packaging gold stamping products, it can effectively reduce production costs and ensure production progress.
