Specializing in deviation and belt breakage, this electrochemical aluminum slitting machine is really stable

In the packaging and printing industry, there is a saying: "Three points of ironing, seven points of cutting".

As the finishing touch of the packaging post-press process, the slitting quality of electrochemical aluminum (hot stamping foil) directly determines the efficiency and yield of the hot stamping process. However, in the face of increasingly thin and wide hot stamping materials, "deviation" leads to waste of edge materials, and "frequent belt breaks" cause downtime losses, which have always been two major "stubborn diseases" that plague many printing companies.

Recently, the new generation of all-servo electrochemical aluminum slitting machine independently developed by Delish was officially put into the market, with its "stable as Mount Tai" slitting performance, it has truly realized the special treatment of deviations and eliminated belt breakage, bringing a "stable" revolution to improve quality and efficiency for industry customers.

1. Precise correction and special treatment of the problem of "deviation"

When the traditional mechanical slitting machine is running at high speed, it is easy to cause the electrochemical aluminum foil to swing left and right during the journey due to fluctuations in unwinding tension or uneven material thickness. This not only causes rough slitting edges, but also leads to the shift of the position of the graphics and texts during subsequent hot stamping, resulting in a large number of waste products.

Our new generation of slitting machines are equipped with "EPC/LPC dual closed-loop hydraulic correction system", which has a response speed of milliseconds. The edge of the material is monitored in real time through high-precision sensors, and with the imported servo drive, it can be reverse compensated at the moment when the material has a slight deviation.

• Result: Whether it is a narrow (5mm) thin cursor or a wide (1.6m) large version of hot stamping foil, the material always runs smoothly in a straight line, and the edges are as neat as a knife, completely solving the problems of "ruffles" and uneven winding caused by running off.

2. Tension intelligent control to end the nightmare of "broken belt"

Electrolysium is an extremely fragile composite material consisting of a PET base layer, a release layer, a coloring layer, and an adhesive layer. If the tension is too large, the material will be stretched, deformed, or even broken; If the tension is too small, it will lead to loose winding and wrinkling.

In response to this pain point, the equipment adopts "five-motor independent drive + full closed-loop tension control system". The system can automatically calculate the optimal taper tension curve for retraction and retraction according to the tensile strength and width of the material.

• Highlights: Tension fluctuations are controlled within a very small range of ±0.5N when the machine accelerates, decelerates or splices materials. This "gentle and constant" stress environment allows low-gram weight and high-sensitivity electroized aluminum foil, which is originally very easy to break, to pass smoothly, truly realizing the "zero break belt" under high-speed slitting.

3. Structural innovation lays the cornerstone of "true stability"

In addition to the intelligent control system, the stability of the mechanical structure is the basis for slitting accuracy. This equipment uses "heavy-duty monolithic cast iron wall panels" and "mirror-grade chrome rollers".

• Shock-absorbing design: The thickened frame effectively absorbs the resonance generated by high-speed operation, ensuring that the tool holder does not move when cross-cutting.

• Optimized feeding path: shortens the suspension distance between the rollers and reduces the interference of airflow on the foil.

• Convenient operation: Equipped with an inflatable shaft and a shaftless hydraulic feeding system, it is easier to change the reel and reduce the uncertainty caused by manual operation.

4. User testimonials: from "usable" to "easy to use" to "inseparable"

In the production workshop of a large cigarette pack printing enterprise in East China, the slitting machine has been running continuously for 800 hours.

"In the past, the imported electrochemical aluminum was okay, but when the domestic material was changed, the belt was always broken, and the coil core was still wrinkled." Mr. Li, the director of the workshop, said, "Since changing this equipment, whether it is a 3-micron film or a thicker laser foil, there is basically no need for manual intervention. The winding end face is as flat as a mirror, and the efficiency is increased by at least 30% when the hot stamping machine is placed accurately. ”

Epilogue

In the printing industry in the era of low profits, every meter of material waste means a loss of profit.

Specializing in deviation is attitude; Eliminating broken belts is technology.

The reason why this electrochemical aluminum slitting machine is "stable" is that it understands the temper of the material and uses precise mechanical design and intelligent control algorithms to pave a "highway" for the fragile electrochemical aluminum foil.
