FUMART Rotary Die Cutting Machine Working Principle, Parameters, and Functions fully details

I. Overview

Round knife machine is a die cutting machine, called "multi-station rotary die cutting machine", referred to as multi-station rotary, commonly known as round knife die cutting machine, hob machine or multi-station hob machine.

Round knife die cutting machine from a simple three stations to five stations, seven stations to the present 32 stations, more and more auxiliary shaft, equipment use is more and more flexible. Rotary die cutting machine adopts servomotor drive, tension control, control precision is relatively high.


2, the working principle of round knife die cutting machine

Round knife machine is a die cutting machine, called "multi-station rotary die cutting machine", referred to as multi-station rotary, commonly known as round knife die cutting machine, hob machine or multi-station hob machine. It in the form of hob continuous rotation die cutting processing, die cutting machine is one of the highest production efficiency of the machine. Divided into 2 seats, 3 seats, 5 seats, 7 seats and other series of round knife die cutting models. Round knife die cutting is through the blade and roller extrusion material to achieve the purpose of die cutting, roller is a smooth surface and hard cylindrical shaft, round knife processing is in a process to complete the composite and processing of multi-layer material die cutting method.

At present, from the point of view of the tension control system of the multi-station round knife die cutting machine, it is generally the use of automatic tension control program, through the pre-set program, automatic calculation of retracting and discharging shaft diameter, timely calculation of torque, so as to ensure the stability of tension. Automatic program tension control system is widely used in Europe and America. In the view of many operators, the program automatic tension control system advantages are very obvious, such as the material does not need to be wound many times; Reduce material scratch, deformation; Easy to operate, easy to upgrade procedures. This is the basic working principle of the round knife die cutting machine.


3, FUMART round knife die cutting machine partial function

Multi - station round knife die - cutting machine is high efficiency, high precision processing equipment.

(2) Asynchronous function: it can realize small piece paste large piece, reduce cost and increase efficiency. Normal tool die through asynchronous virtual setting of a tool shaft (sliding material), to make small pieces of composite to large products, that is to save the cost of the tool die, but also save the cost of materials.

(3) The function of cutting (sticking) irregular sheet (graphite sheet) : you can cut irregular sheets into regular, unequal spacing sheets, you can also arrange unequal spacing sheets into equal spacing sheets, and then accurately compound equal spacing sheets into products. Suitable for special materials and complex technology.

(4) Multiple groups of asynchronous parameter setting, you can set one to four groups of different jump distance, powerful, flexible setting.

(5) Automatic tracking and adjustment function: can realize automatic adjustment of sleeve cutting size or post-press die cutting, in accordance with the set size alignment, set accurate, high degree of automation, labor saving.

(6) Independent servo control: can realize separate start and stop, positive and negative rotation, proportional/synchronous. Set the follow speed arbitrarily.

(7) Automatic constant tension control, automatic cutting protection, torque changes with the size of the diameter, to maintain constant tension.

(8) Automatic correction function: it can realize automatic correction of main materials.

(9) With safety protection function, the maximum protection of personal safety. High safety factor, simple and convenient operation.

6. Precautions for FUMART multi-station round knife die Cutting Machine

1). Do not knock the edge when adjusting the gap of the edge to prevent the edge from cracking. Generally, adjust the lower tool position before adjusting the blade clearance. During the adjustment, loosen the fastening bolts on the blade base using a professional tool, move the blade base to the proper position, and then tighten the fastening bolts.

2). the operator must be familiar with the general structure and performance of the equipment, it is strictly prohibited to use the equipment beyond the performance. The mold on the operating platform has been positioned after accurate adjustment by the manufacturer, and shall not be adjusted unless special circumstances.

3). Adjust the upper tool in the same way as the lower tool. Adjust the upper tool to an appropriate gap according to the thickness of the cutting plate, and align the upper and lower press wheel with the tool. Adjust the position of each tool in turn.

4). Clean the workbench and its surrounding tools and items unrelated to work before starting. Switch on the main power supply, then close the speed control box switch, adjust the rolling speed. The procedure is reversed when the machine is shut down.

7, Rround knife die cutting machine maintenance method

1). die cutting carton will produce a lot of waste paper edge, paper wool, a little attention will enter the chain transmission parts, die cutting part of the moving platform and some rotating motion parts, and may block the photoelectric detection, causing failure. Therefore, be sure to clean the body of the round knife die cutting machine.

2). operate in strict accordance with the operating procedures, the blade must always keep clean, unpainted part of the anti-rust grease.

3). Check and repair the switch, safety and handle regularly to ensure its reliability.

4). It is strictly prohibited for non-designated personnel to operate the equipment, and it must be stopped when people leave the plane.
