A rewinder is a kind of papermaking equipment. After the paper passes through the equipment, it is made into finished paper and leaves the factory. At present, the use of AC drives instead of DC drives in equipment has become a development trend in the tissue processing equipment industry.

Rewinders are mainly used to convert large toilet paper from single-layer rewinders and slitters into single-layer, two-layer or three-layer specifications for folding paper towels, napkins, boxed facial tissues, etc.

Equipment failures will be encountered when using the equipment, and the daily maintenance is as follows:

1. Transmission devices, such as gear chains, need to be lubricated for a period of time.

2. There is usually no problem with the rewinder, and the wearing parts are just pinions. If you add another one, the printing knife will be easily broken. After a year and a half of use, the wool roller will become thinner. It needs to be sent back to the factory for repair. If it is necessary to replace the embossing pattern on the embossing device of the steel roller, the steel roller needs to be transported back to the original factory for transformation, which is not costly.

The winder must be operated by a fixed person who can master start-up and bag-making procedures, simple instrument commissioning and parameter modification. Mechanical instrument commissioning personnel need to have strict requirements for manufacturers, and can master instrument performance, working procedures, operating modes, working states and common fault elimination; It is strictly forbidden to operate computer instruments without personnel.

The daily basic cleaning of the equipment needs to keep the inside and outside of the computer instrument box clean and dry; Check for loose or detached timing terminals. Make sure the circuit and air path are clear.

Basic cleaning of the winder includes:

1. The metering part of the equipment should be cleaned in time after shutdown, for example, the packaging is sugar, plate blue root granules, salt, etc. It must be ensured that the unloading tray and turntable of each shift are cleaned to prevent corrosion.

2. The body of the heat sealer should be cleaned frequently to make the texture of the equipment seal clear.

3. The photoelectric follow-up light-emitting head, that is, the electric eye, should also be cleaned regularly to ensure that the cursor follow-up error is small.

4. The scattered materials on the pallet should be cleaned up in time to keep the parts clean.

5. Clean the dust in the electrical cabinet regularly to avoid failures such as poor contact. The newly installed rewinder requires the transmission and moving parts to be inspected, tightened, refueled and maintained within a week. Regular inspection and maintenance are required monthly.

Paper machine, as the name implies, is a kind of equipment used for papermaking, and the emergence of this equipment brings great convenience to our lives, and what parts are composed of this magical equipment? In view of this, the paper machine manufacturer - Haitian Paper summarized a few points, I hope it can be helpful to you.

Paper machine common failure analysis

The performance of the paper machine control system is the premise of determining whether a paper machine can produce with high efficiency and high quality, and for a normal paper machine, in order to ensure its continuous high efficiency and high quality production, the maintenance of the transmission system is particularly important.

What is a slitter rewinder's cleaning device?

The slitter rewinder includes a rack equipped with a paper stock rack, a paper feeding mechanism, a rewinding station, a paper cutting tube station and a conveyor mechanism.

Paper machine basic classification

According to the needs of the copying process, the structure of the paper machine is diverse, generally composed of flowing, forming, pressing, drying, finishing, winding and transmission and auxiliary equipment and other supporting equipment.
