First, definition and Function
1. Rewinder
• The rewinder is an indispensable equipment in the printing contour processing process, which is mainly used to rewind large rolls of printing materials (such as paper, plastic film, etc.) into the required small rolls of materials.
• In the papermaking machinery industry, the rewinder is often used to rewind the paper rolls (base paper rolls) produced by the paper machine in turn to form finished paper rolls with certain specifications and certain tightness requirements.
2. Slitting machine
• Slitting machine is a processing equipment that cuts large rolls of materials into specified sizes and lengths, mainly used to cut wide paper, film, mica tape and other materials into multiple narrow strips.
• Slitting machines are widely used in papermaking machinery, wire and cable mica tape, printing and packaging machinery and other fields, and can cut out various specifications of coils, such as 3mm, 5mm, 10mm, etc.
Second, use scenarios and product specifications
1. Usage scenarios
• The rewinder is usually used as a necessary equipment in the finished product barcode printing, secondary processing and other links, and is also commonly used for the rewinding and slitting of mica tape, paper and film.
• The slitting machine is mainly used in the automatic production line for continuous cutting and processing of coils, especially suitable for the slitting of narrow strips (such as non-woven fabrics, paper, insulating materials, mica tape, films, etc.).
2. Product specifications
• The material specifications of the rewinder after rewinding are relatively simple, mainly small roll materials.
• The slitting machine can cut a variety of coils of various specifications, and the specifications of the products are more diversified.
Third, structure and characteristics
1. Rewinder
• The rewinder usually has functions such as automatic trimming, glue spraying, sealing, etc., which are used to improve the quality and aesthetics of the product.
• The longitudinal knife system of the rewinder has no driving force, and the longitudinal knife is driven by the rotation of the paper roll to cut the paper, so there may be problems such as paper powder and paper wool.
2. Slitting machine
• The slitting machine has a high-precision photoelectric deviation correction system, which can ensure the precision and stability of cutting.
• The slitting machine is usually controlled by dual inverter motors, so that the rewinding material can still maintain a stable cutting effect when the diameter of the rewinding material becomes larger.
• The slitting machine also has the functions of fixed-length automatic shutdown, automatic length metering, etc., which improves the production efficiency.
To sum up, there are obvious differences between the rewinder and the slitting machine in terms of definition and function, use scenarios and product specifications, and structure and characteristics. In practical application, the appropriate equipment should be selected for processing according to the different production needs and product specifications.
