How To Do The Daily Maintenance Of The Rewinder

The rewinding machine is a kind of special equipment used for paper and film. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the paper machine in sequence, and the paper is made into finished paper after rewinding. At present, it has become a development trend in the papermaking machinery industry to replace DC transmission with AC drive for rewinders. The paper roll rolled by the paper reel is relatively soft, and may be damaged or broken inside, the edges on both sides are not neat, and the width of the paper web cannot be directly used in paper processing or printing machines. Most paper types (such as newsprint) , Letterpress printing paper, packaging paper, etc.) must be trimmed, slit, spliced, and re-rolled on the core of the paper roll to form a finished paper roll with a certain specification and certain tightness requirements before it can leave the factory. So, how does the daily maintenance of the rewinder need to be done? Let's take a look at the introduction of Shandong Haitian Paper Machinery Co., Ltd. for us.

[How to do the daily maintenance of the rewinder]

The rewinding machine must be operated by a fixed person who is able to operate the packaging machinery and equipment, and can be proficient in the start-up and bag making procedures, and can simply debug the instrument, change the parameters, etc.; the mechanical instrument debugger must be strict with the manufacturer and be able to master the performance of the instrument. Working procedures, operating modes, working status, common troubleshooting and handling; it is strictly forbidden to operate computer instruments without personnel. The daily maintenance of the rewinder must ensure that the inside and outside of the computer instrument box are clean and dry; regularly check that the wiring terminals are not loose or falling off. Ensure that the circuit and gas path are unblocked.


1. Regularly check the screws of each part of the packaging machine to avoid loosening;
2. Pay attention to the waterproof, moisture-proof, anti-corrosion and rat-proof of the electrical part of the rewinder. The inside of the electric control box and wiring terminals must be kept clean to prevent electrical failure;
3. When the rewinder is stopped, the two heat sealing rollers should be in the open position to prevent the packaging materials from being scalded;
4. Lubricate the gear meshes of the rewinder, the oil hole of the bearing with a seat and all the moving parts regularly. When adding lubricating oil, please be careful not to drop the oil on the transmission belt to prevent slipping and loss of rotation or belt aging damage;
5. The transmission and moving parts of the newly installed rewinder must be inspected and tightened within one week of use, and oiled for maintenance; thereafter, it must be inspected and maintained regularly every month.
