What is a rewinder? What are the characteristics?

  • This is an article introducing the rewinding machine. The rewinding machine supplier Deguang introduces in detail the performance characteristics, operation precautions, and preparations before the operation of the rewinding machine.

    About the introduction of the rewinding machine, what is the rewinding machine?

    A rewinding machine is a special machine for film and paper. This kind of machine equipment mainly rewinds the paper rolls produced by the paper machine in sequence, and the paper is made into finished paper after rewinding before leaving the factory. For now, the use of AC drives instead of DC drives in rewinding machines has become a trend in the paper machinery industry.

    The paper roll produced by the reeling machine will be relatively soft, the interior may be damaged or broken, the edges on both sides are uneven, and the width of the paper web cannot be directly used in some machines such as paper processing or printing. Most paper types (like newsprint, wrapping, etc.) need to be slit across the edge of the rewinding machine, seamed, and rewound on the roll core to form some degree of the finished roll before leaving the factory. The rewinding process mainly completes three steps: first, cut off the raw edges of the base paper, then cut the whole base paper into several widths that meet the user's requirements, and then control the diameter of the finished paper roll to make it meet the factory specifications.

    What are the performance characteristics of the rewinding machine?

    1. The rewinding machine is mainly controlled by a PC or manual operation. It has very reliable performance and a high degree of automation. It can also automatically identify wrong commands and avoid some accidents caused by wrong operations.

    2. The precompiled process program can be locked because the operator cannot change the program without authorization, thus ensuring the quality of the pressed product.

    3. The rewinding machine also has the good functions of timing mold opening, automatic deflation, and automatic pressure compensation.

    4. Three operating modes can be selected at will: manual, automatic, and electric.

    5. Electric heating press uses a digital display to control temperature.

    The following preparations should be carried out before the rewinding machine is commissioned:

    1. Add lubricant according to the requirements of equipment technical documents.

    2. There should be a gap between the tool shafts of the longitudinal device, and the size of the gap should meet the requirements of the equipment technical documents.

    3. The piston rod of the pushing device should be in the non-working position.

    4. The product quality certificate should be checked before the rewinding machine is assembled. The specifications and models of the machine and equipment need to comply with the relevant regulations of the design documents.

    The operation and maintenance of the rewinding machine:

    Although the rewinding machine is small, regular maintenance and storage by professionals are required, and the operator is also familiar with the structure and performance of the machine. In addition, it is strictly forbidden to overload the circular rewinding machine.

    1. The blade of the rewinding machine should be kept sharp. If the blade becomes dull or damaged, it must be repaired or replaced in time. When carrying out multi-person operations, there should be a special person to direct and coordinate. In addition, it is forbidden to cut two materials of different specifications at the same time on the rewinding machine, and overlapping cuts are not allowed, which will also damage the machine.


    2. The workpieces cut by the rewinding machine must be placed stably, not too high, or on the aisle. Operators should also clean up the remaining materials and waste time to keep the site clean and tidy.

    The above is all the content about the rewinding machine brought to you today by the rewinding machine manufacturing company. I hope the above content can help you get to know the rewinding machine initially. More information on the machinery industry is continuously updated, and we will see you in the next issue.
