Rewinding Machine safety operation guide -
Fourth, joint operator joint quality:
1 found that the paper has a broken rewinder
2 peel off the damaged paper that affects the quality at the break of the rewinding and rewinding paper roll, and draw the paper edge Qi.
3 first cut a piece of paper, paste double-sided tape (or according to process requirements)
4 Stick the other side of the paper together, cut the paper, and attach the connector label.
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.
Design and application of constant tension and load distribution control for winder---
2Rewinder control research status at home and abroad
Rewinding machine is an important papermaking machine. It is usually installed behind the paper machine. Its speed should be 2-3 times of the speed of the paper machine, generally 1500-1800m/min, up to 300om/min. When threading, run at a maximum speed of 1:100. In order to ensure continuous paper and loose paper during the rewinding process, the tension of the paper web must be kept constant; in order to ensure the tight and loose quality inside the finished paper, the load distribution of the front and rear bottom roller motors must be performed. Therefore, the main performance requirements of the rewinder for the electric drive system are long-term linear speed, adjustable speed and wide speed range, and fast response.
The control of the early rewinder is mainly based on DC drive, and the DC control system is composed of discrete components or analog regulators to realize the above control functions. Since the transmission of analog signals requires a one-to-one physical connection, the signal changes slowly, which increases the overhead of computer speed and accuracy, and the anti-interference ability of signal transmission is poor, and paper breakage and wrinkling often occur in the production process. So in the mid-to-late 1980s, the analog regulator was replaced by a digital regulator, and the DC digital control system of the winder appeared. This control system is more stable, reliable and suitable for maintenance than the analog system, and is more suitable for interface with the factory computer. In the mid-1990s, most of the newly-invested rewinders in the domestic paper industry used all-digital DC-speed converters produced abroad, and the more famous ones were the 6RA7O series from Siemens and the 590 series DC-speed converters from Continental Transmission.
Due to the DC motor commutator and the brush, under the stable conditions, the design speed of the winder can only reach 1800m/mni, and the accuracy of the digital regulator is still limited to about 0.08% of the maximum speed, which can not meet the high speed paper. The matching requirements of the machine (the speed of the winder should be 2-3 times the speed of the paper machine). In the early 1980s, European and Japanese developed AC variable frequency speed control devices. This technology was successfully introduced to the United States in the mid-1980s and used in rewinders. The biggest advantage of the AC drive is that the AC motor is simple in construction and reliable in operation, and it requires much less maintenance and repair than DC motors.
