Working Principle of Vertical Automatic Roll Change Slitter

Advantages of this series of machinery and equipment:

● Non-stop production: Automatic roll change and material splicing minimize downtime and greatly boost productivity.

● Labor saving: Reduce manual work for roll replacement, well suited for automated production lines.

● High slitting quality: Precision knives and stable tension system ensure clean cuts and wrinkle-free rolls.

● Reliable operation: Optimized mechanical and electrical structure, low failure rate for mass continuous production.

● Wide compatibility: Applicable to various rolls with different materials and thicknesses.

● Low material loss: Continuous material feeding cuts waste during roll change.

Frequently Asked Questions
Find answers to common questions about our machines and services
What products do we manufacture?

We mainly produce slitting machines, inspection machines, and cross-cutting machines in various models and specifications.

What are the advantages of automatic tension control equipped on automatic slitting machines?

Automatic tension control maintains constant material tension during slitting and rewinding processes, so as to improve finished product quality and production efficiency.

How does the automatic edge guiding system of automatic slitting machines work?

The automatic edge guiding system detects material position via sensors such as ultrasonic sensors or CCD sensors. Once material deviation occurs, the edge guiding controller sends commands to actuators to automatically correct the material position. In addition, the system supports tracking of printed registration marks.

What are the maximum unwinding and rewinding diameters? What is the load capacity?

The vertical standard models feature winding diameters of 600 mm and 800 mm, with unwinding diameters of 800 mm and 1000 mm; the horizontal standard models have winding diameters of 600 mm, 800 mm, and 1200 mm, with unwinding diameters ranging from 1200 to 1600 mm. Different models support unwinding loads up to 1500 kg or even over 3000 kg. Customized solutions for specific dimensions and load requirements are available upon request.

Can the slitting width be customized? How many strips can be slit simultaneously?

Yes, slitting width can be customized, with the minimum slitting width down to 10mm. The number of simultaneously slit strips depends on the total material width and minimum slitting width. For example, a 1600mm wide machine can slit up to 32 strips of 50mm wide products.

What optional functions do you have? Which ones are more practical?

Practical optional features include: 6-inch rewinding shaft (suitable for large-diameter rewinding), Automatic paper feeding tube (enhances production efficiency and accuracy); automatic blade leveling/milling mechanism (reduces manual adjustment time); automated packaging function (simplifies packaging process); automatic waste edge winding device, etc.

What is the warranty period of the equipment? What are the wearing parts? What is the replacement cycle?

The whole machine warranty period is 1 year, and core components (servo motors, PLC) have a 2-year warranty. Wearing parts mainly include knives, belts, sealing rings, bearings, etc. Knife replacement cycle is 1-3 months (depending on material hardness and usage frequency), belts 3-6 months, bearings 6-12 months. We will provide a list of common wearing parts and preferential spare parts prices.

How long does installation and commissioning take? Will you send someone to provide on-site training?

Standard model installation and debugging take 3–5 days. For international customers, we dispatch professional engineers to perform on-site installation and debugging, along with 1–2 days of training for operators covering equipment operation, daily maintenance, and common troubleshooting.

What should I do if the equipment breaks down? How fast is your after-sales response?

We provide 7×24 hours technical support, and general faults can be solved through remote guidance. For home visits, we will arrange them within 48 hours.
