Rewinding Machine Structure - Pressure Mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work.
The paper roll is slippery because the paper roll is too light and the take-up is too tight because the pressure is too high until the rewinding to the late stage. In the modern rewinder system, the platen roller is automatically controlled so that additional weight can be applied to the paper web. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is passed to the pressure program control unit,
To calculate the pressure, so that the oil pressure in the scale can be changed, thus achieving the pressure control of the platen roller.

Second, the system configuration
1. Main transmission part: 1 set of paper-removing brake generator, 400kW (YVP4501-6 or
1LA8357-6), one roller motor (YVP225S-4), 37kW, two pressure roller motors (YVP132S-4), 5.5kW, two coiling motors (YVP355L2-4) (one for each front and rear roller) , 315kW, 6 paper cutter motor, 0.55kW, total installed capacity 1082kw (model and power are subject to final design). The rectification feedback and the inverter unit and the tension controller matched with the above constitute a transmission control system.
2. Logic control part: PLC host 1 block.
3. The logic control system selects the S7-400 series products of SIEMENS.
4. Tension control part: 1 set of tension detection and control system, using Sweden
5. 1 set of coiling roller pressure detection and control system.
6. The diameter detecting sensor of the take-up roller.
7, with position detection, pressure detection, liquid level detection, safety detection sensor and phase
The control agency should be controlled.
8. On-site operation panel, logic control panel, and electric drive panel.
What is a fully automatic winder---
The shortage of workers and the lack of employment are the actual problems faced by enterprises in the current period. In addition to the fierce competition in the current market price war and other factors, it is undoubtedly worse for enterprises. Transforming and upgrading equipment is fundamental to reducing costs today. For the needs of the market, our Zhengzhou Guolian Machinery Factory is in a hurry to develop the plastic machinery supporting equipment ------- automatic rewinding machine.
Automatic rewinding machine - role and purpose
Instead of the previous manual and manual semi-automatic secondary rewinding. It effectively improves work efficiency, reduces and saves the problem of labor and workers' wages, and is a fully automated production supporting equipment that is indispensable for enterprises to directly reduce production costs.
Automatic rewinding machine---function and use
In order to meet the different needs of customers for the length and width of the product. Carrying on cling film, wrapping film, stretching
Secondary rewinding of film, aluminized film, paper, non-woven fabric, etc. Replacing previous manual operations and manual semi-automated work. Improve the cumbersome and heavy work procedures and manual labor and the lack of labor and reduce unnecessary expenses, improve work efficiency, and thus achieve the purpose of reducing production costs.
