Mill Roll Stand

Stable Roll Support and Smooth Paper Feeding for Reliable Corrugator Production

Mill Roll Stand Overview

The mill roll stand is an auxiliary piece of equipment in a corrugated board production line. This equipment is mainly responsible for supplying paper to the corrugator machine. It is designed to support, lift, clamp, and position large base paper rolls, ensuring stable and continuous base paper feeding to the corrugator line. Through stable roll positioning and precise tension control, the shaftless mill roll stand helps reduce paper deviation and breakage. It makes the subsequent processing smoother and improves production efficiency and product quality.

According to the differences in mill roll stand structure, the mill roll stand is divided into the shaftless and shafted types. The shaftless mill roll stand relies on greater automation, faster roll changes, and more stable tension control, making it a widely used type of equipment in modern corrugated production lines.

Hydraulic Shaftless Mill Roll Stand

The hydraulic shaftless mill roll stand mainly uses a hydraulic power system to drive the mechanical arms, realizing paper roll clamping, lifting, and adjustment. It also adopts shaftless expansion chucks to secure the paper roll core. This can improve roll-changing efficiency and reduce paper waste. The hydraulic shaftless mill roll stand has some advantages, including strong load capacity, smooth movement, and stable hydraulic movement. This equipment is suitable for high-speed corrugated board production lines with large paper rolls.

Electric Shaftless Mill Roll Stand

The electric shaftless mill roll stand is used to support and clamp the paper roll. The movement and positioning of the mill roll stand are controlled by electric motors. Compared with a hydraulic structure, the electric shaftless mill roll stand has faster response, higher control accuracy, and easier maintenance.

corrugator machine manufacturer

As a professional , AGICO PAPER offers two types of mill roll stands: hydraulic shaftless mill roll stand and electric shaftless mill roll stand for corrugator line. They meet different customers' demands for production speed, automation level, and budget. Whether you use it on medium- and high-speed, large-scale production lines or on a stable economic production line, AGICO PAPER can provide the proper mill roll stand solution.

Efficient Roll Changing

The shaftless design of the mill roll stand adapts to the corrugated line's frequently changing paper rolls. It can improve the base paper replacement efficiency.

High Load Capacity

The hydraulic system can handle heavy paper rolls easily.

Precise Control

The hydraulic system makes the paper roll stable and cooperates with the braking system to maintain stable paper tension.

Wide Applicability

This machine is used for different production requirements of the corrugated board production line.

Electric Drive

The electric drive system replaces the hydraulic system. It can improve the equipment response speed.

Energy Saving Design

There is no hydraulic oil consumption. It can reduce hydraulic system maintenance requirements and lower operating costs.

Low Maintenance Cost

This machine’s structure is simple, without hydraulic components, eliminating oil changes and seal replacement, reducing maintenance costs.

Hydraulic vs Electric Mill Roll Stand

Due to differences in drive method and control method, there are differences between the electric shaftless mill roll stand and hydraulic shaftless mill roll stand following table.

Comparison Item	Hydraulic Shaftless Mill Roll Stand	Electric Shaftless Mill Roll Stand
Drive System	Hydraulic system drive	Electric motor drive
Structure	Heavy-duty double-arm symmetrical structure	Compact single-slide structure
Supported Paper Roll Diameter	Max. 1500 mm	1400 mm
Load Capacity	3-5T	Approx. 2T
Tension Control	Multi-point braking system	Disc-type manual brake
Maintenance Cost	Higher	Lower

If your production line is high-speed and needs to load large paper rolls, the hydraulic shaftless mill roll stand is a good choice for you. For customers with small- to medium-sized production lines or who prioritize operational convenience and maintenance costs, the electric shaftless mill roll stand can offer a more affordable solution.

Key Advantages of AGICO Mill Roll Stand

Support Continuous Production

AGICO PAPER shaftless mill roll stand can be used together with automatic splicers to complete paper roll changes during high-speed production, reducing downtime and improving the corrugator line's overall operating efficiency.

Reduce Paper Waste

This machine uses multi-point brakes and manual tension brakes to ensure precise tension control. The top of the mill roll stand adopts a serrated clamping chuck, which improves paper roll clamping stability and reduces paper waste and breaks.

Flexible Configuration Options

AGICO PAPER offers different specifications and configurations of shaftless parent roll stands. They are used for corrugated board production lines with different widths, weights, and production speeds. Provides a flexible choice.

Improve Automation Level

Through the hydraulic or electric control system, this corrugator equipment realizes paper roll lifting, clamping, and positioning. It also reduces manual adjustments, improving the roll change efficiency.

Working Principle of Mill Roll Stand

The shaftless mill roll stand mainly works by supporting, clamping, and positioning the paper roll. It uses the tension control system to keep stable tension during unwinding. This also ensures smooth and continuous paper feeding to the corrugator.

Paper Roll Clamping

The equipment adopts a four-arm structure and clamps the paper core through chucks. This keeps the paper roll stable during high-speed operation.

Paper Roll Alignment

The equipment is driven by a hydraulic or electric system, lifting the paper roll to the working position and adjusting its position. This ensures stable paper feeding and reduces deviation during operation.

Constant Tension Control

The multi-point brake and disc-type manual brake adjust the paper roll tension to maintain stable unwinding.
