How to rewind jumbo roll efficiently?
In the toilet paper processing industry, the rewinder, as one of the core equipment, directly determines the production efficiency and quality of the finished product. Today we will focus on a rewinding device that is professionally used to rewind large rolls of base paper (Jumbo Roll) into small rolls of long toilet paper. By analyzing its functions, model parameters and technical highlights, we will provide selection references for industry users.
1. Core functions and applicable scenarios of the equipment
This toilet paper roll rewinding machine is designed for the post-processing of toilet paper. Through the functions of synchronous conveying of the unwinding rack, precise slitting and rewinding, and automatic punching, it can efficiently convert large rolls of base paper with a width of 1800-3500mm into finished small rolls with a diameter of 50-1800mm. Its applicable scenarios include:
Large-scale production of household rolls (medium and low weight);
Processing of customized long toilet paper in the hotel and catering industry;
Secondary slitting service of base paper supplier.
2. Model parameter analysis: How to select from 1575 to 3500?
According to the base paper width and production capacity requirements, this series of rewinders provides 5 mainstream models (1575/1760/1880/2800/3500)
1575/1760: Suitable for small processing plants with a daily output of less than 5 tons, taking into account cost-effectiveness and flexibility.
1880/2800: Recommended for medium-sized enterprises, which can meet diversified order requirements (such as finished products with different diameters and weights).
3500: For ultra-wide base paper (such as 3500mm), suitable for large-scale paper mills or OEM companies.
3. Technical highlights: How to achieve efficient and stable production?
Three-layer synchronous paper unwinding rack design
Adopting three-layer base paper synchronous transmission technology, it supports continuous loading of large rolls with a diameter of less than 1100mm, reduces the frequency of paper replacement, and improves production capacity utilization.
Stepless frequency conversion speed regulation system
The 5.5-15kW power configuration is combined with the frequency conversion speed regulation function, which can flexibly adjust the speed according to the base paper weight (14-40gsm), while ensuring the slitting accuracy and avoiding paper breaks.
Intelligent punching and tension control
Equipped with 2-blade/3-blade punching knife group, the spacing covers 80-300mm, which can meet the needs of different products such as paper drawing and paper rolling;
PLC system monitors tension in real time to ensure uniform tightness of finished rolls (diameter error ≤±1mm).
Pneumatic system optimization
It needs to be equipped with a 3-horsepower air compressor (air pressure ≥5kg/cm²), and the pneumatic pressure roller can be used to achieve fast roll change and reduce the intensity of manual intervention.
4. User pain point solution
In actual production, the rewinding link often faces the following problems, and the equipment has designed a targeted solution:
Poor compatibility of base paper → Support 76mm standard paper core (other specifications can be customized), suitable for more than 90% of base paper suppliers on the market.
Low slitting efficiency → Maximum processing speed of 280 meters/minute, single-shift output can reach 15-20 tons (depending on the base paper weight).
Low qualified rate of finished products → The human-machine interface presets parameter templates, and one-click switching of different specifications reduces human errors.
