Explanation Of The Working Principle Parameters And Applications Of Fumart Automated Rotary Die Cutting Machine

A rotary die cutting machine is a precision tool utilized in various industries for cutting and shaping materials with intricate designs. Its working principle involves a rotating cylindrical die that presses against the material to cut it into the desired shape. The die is typically customized to match the specific design requirements of the product being produced.

Parameters such as cutting speed, pressure, and blade sharpness can be adjusted to achieve different cutting results, ensuring precision and consistency in the production process. Additionally, some advanced rotary die cutting machines may incorporate automation features for enhanced efficiency and accuracy.

The primary purpose of a rotary die cutting machine is to mass-produce products with complex shapes or patterns, such as labels, stickers, gaskets, and electronic components. Its high-speed operation and customizability make it ideal for applications where precision cutting is essential, enabling manufacturers to meet the demands of various industries effectively.

I. Overview

The rotary cutter machine is a type of die cutting machine, also known as a "multi-position rotating die cutting machine," commonly referred to as a rotary die cutting machine, rotary knife machine, or multi-position rotary knife machine.

From a simple three-position design, the rotary die cutting machine has evolved to five positions, seven positions, and currently up to eighteen positions, with more auxiliary shafts being incorporated, making the equipment increasingly flexible. The rotary die cutting machine often employs servo motor drive and tension control, resulting in high precision control.

II. Working Principle of Rotary Die Cutting Machine

The rotary cutter machine is a type of die cutting machine, also known as a "multi-position rotating die cutting machine," commonly referred to as a rotary die cutting machine, rotary knife machine, or multi-position rotary knife machine. It continuously rotates in the form of rotary knives for die cutting processing, making it one of the most efficient types of die cutting machines in terms of production efficiency. The rotary die cutting machine comes in different series such as 2, 3, 5, and 7-position models. Rotary die cutting is achieved by squeezing the material between the blade and an anvil roller to achieve the die-cutting purpose, with the anvil roller being a smooth and hard cylindrical shaft. The process of rotary die cutting involves the composite and processing of multiple layers of materials.

Currently, in terms of tension control systems for multi-position rotary die cutting machines, automatic tension control programs are generally used to calculate the diameter of the unwinding and rewinding shafts and the torque in real-time to ensure stable tension. The automatic tension control system is widely adopted in Europe and America. The obvious advantages of the automatic tension control system include eliminating the need for multiple winding cycles, reducing material scratches and deformations, easy and convenient operation, and simple program upgrades. This is the basic working principle of the rotary die cutting machine.

VI. Usage Precautions for FUMART Automated Multi-position Round Blade Die Cutting Machine

1. Do not knock the blade when adjusting the blade clearance to prevent blade breakage. When adjusting the blade clearance, it is generally necessary to adjust the lower blade position first. Use professional tools to loosen the fastening bolts on the blade base, move the left and right movable blade base to the appropriate position, and then tighten the fastening bolts.

2. Operators must be familiar with the general structure and performance of the equipment, and strictly forbid exceeding the performance when using the equipment. The positioning of the mold on the operating platform has been precisely adjusted by the manufacturer. It should not be adjusted unless necessary.

3. The method of adjusting the upper blade is the same as the lower blade. Based on the thickness of the cutting board, adjust the upper blade to the appropriate gap and align the upper and lower pressure wheels with the blade. Adjust the positions of the various cutting tools in turn.

4. Before starting the machine, clean the workbench and surrounding tools and items that are not related to the work. Turn on the main power supply, then close the speed control box switch and adjust the roller speed. The shutdown process is the reverse of this.

Maintenance Methods for Round Blade Die Cutting Machines

1. When die-cutting paper boxes, a large amount of waste paper edges and paper debris will be generated. If not careful, they may enter the chain drive parts, die-cutting platform, and some rotating parts, and may block photodetectors, causing malfunctions. Therefore, the body of the round blade die-cutting machine must be cleaned thoroughly.

2. Operate strictly according to the operating procedures. The blades must be kept clean frequently, and rustproof grease should be applied to unpainted parts.

3. Regularly inspect and repair switches, fuses, handles to ensure their reliable operation.

4. Non-designated personnel are strictly prohibited from operating the equipment, and the machine must be stopped when people are away from it normally.
