Paper tube machine manufacturers introduce the price advantage of their products: According to the degree of intelligence, paper tube machines can be divided into: intelligent CNC spiral paper tube machines, program-controlled spiral paper tube machines. The progress of human beings and the development of science and technology are inseparable, and at the same time, the performance of products is continuously improved. Now there are manufacturers of products everywhere, so you need to fully understand before buying.
Operation principle of paper tube machine under different control systems
1. From the working mode of the paper tube machine, in the relay control circuit, when the power is turned on, all the relays in the circuit are in a restricted state, that is, the pull-in relays are pulled in at the same time. The relay is limited by certain conditions and cannot be pulled in. This kind of working mode is called parallel working mode. The PLC's user program is executed in a certain sequence. Therefore, each soft relay is in a cyclic scan. The sequence of each relay subject to the same condition is determined by the sequence of the program scan. This working method is called serial. Way of working. 2. From the control method of the paper tube machine, the control logic of the electrical control system adopts hardware wiring, and the control logic of the relay's mechanical contacts is connected in series or parallel. The PLC uses computer technology, and its control logic is stored in the memory in the form of a program. To change the control logic, you only need to change the program, so it is easy to change or add system functions.
Tips: Nowadays, there are so many product manufacturers. Choosing a factory that suits you requires multiple inspections. The birth of the product has brought many conveniences to human life, and the product is not static, but is constantly innovating with the development of science and technology.
