Working principle of circular or rotary die cutting machine
I. Overview
Round knife machine is a kind of die cutting machine, full known as "multi-station rotary die cutting machine", referred to as roll cutting machine or rotary machine, commonly known as Circular knife machine, hob machine or multi-station roll cutter.
The circular knife die cutting machine has developed from a simple three stations to five stations, seven stations to the present 18 stations, more and more auxiliary shafts, and the use of equipment is more and more flexible. rotary die cutting machine mostly adopts servo motor drive, tension control, control accuracy is relatively high.
2. the working principle of the rotary die cutting machine
Roll cutting machine is a kind of die cutting machine, full known as "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. Roll cutting is to achieve the purpose of die cutting through the blade and the roller extrusion material, the 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 rotary die cutting machine, it is generally the program of automatic tension control, through the pre-set program, the automatic calculation of the reel diameter of the retracting and discharging shaft, and the timely calculation of the torque, so as to ensure the stability of the tension. Automatic tension control system is widely used in Europe and America. In the view of many operators, the advantages of automatic tension control system are very obvious, such as the material does not need to be wound multiple times; Reduce material scratching and deformation; The operation is simple and convenient, and the program is easy to upgrade. This is the basic working principle of the round knife die cutting machine.
3. Xiaoniu technology round knife die cutting machine part of the function
Multi-station round knife die cutting machine is high efficiency, high precision processing equipment. The equipment is widely used in the die-cutting of electronic adhesive accessories such as mobile phones, digital cameras and computers. It has the advantages of multi-layer composite, multi-die cutting, waste discharge, multi-group winding and unwinding simultaneously, advanced technology, reasonable process, compact structure, flexible and convenient operation, and high production efficiency. Strong ability to adapt to different product processes, die-cutting quality and production efficiency are much higher than other die-cutting methods, is the ideal choice for die-cutting products to improve production capacity and reduce production and operating costs. In order to adapt to different specifications of die-cutting products, die-cutting equipment can be customized according to the requirements of die-cutting manufacturers.
(1) Two-speed function: one device can be used as two devices. Each tool holder can achieve system switching, any combination of each tool holder, flexible setting, independent counting, start-stop control, do not affect each other.
(2) Asynchronous function: It can achieve small pieces with large pieces, reducing cost and increasing efficiency. Normal 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 die, but also save the cost of materials.
(3) The function of cutting (sticking) irregular sheets (graphite sheets) : the irregular sheets can be cut into regular, unequal spacing sheets, and the unequal spacing sheets can be arranged into equal spacing sheets, and then the equal spacing sheets are accurately compounded into the product. Suitable for special materials and complex processes.
(4) Multiple groups of asynchronous parameter Settings, you can set one to four different groups of jump distance, powerful, flexible Settings.
(5) Automatic tracking, adjustment function: can achieve automatic adjustment of the sleeve cutting size or post-press die cutting, according to the set size alignment, set accurate, high degree of automation, labor saving.
(6) Independent servo control: can achieve separate start and stop, positive and negative rotation, ratio/synchronization. Set the follow speed arbitrarily.
(7) Automatic constant tension control, automatic cutting protection, torque changes with the size of the roll diameter, maintain constant tension.
(8) Automatic correction function: automatic correction of main materials can be achieved.
(9) With safety protection function, maximize the protection of personal safety. High safety factor, easy to operate.
(10) In addition to electrostatic function: eliminate the static electricity and dirt of the material, improve the quality of die cutting.
