Rewinding Machine safety operation guide - 

First, prepare for work after taking over:
1. It is necessary to arrive at the post, check, and original record 15 minutes earlier. Comprehensive understanding of the above
The operation of a class of equipment, the quality of rewinding and safety.
2. Understand whether the previous class of paper is good; whether the class changes specifications, the weight and change
time. Check if the shift is cleared in the previous shift.
3, the middle and night shift rewinders must check whether the rewinding paper core tube and packaging materials are adequate.
4,Report the handover to the squad leader

Seventh, production operations and quality control during the rewinding process:

4, pay attention to the quality of the rewinding of the paper roll when rewinding, found zigzag, knife, running,
If the color difference is serious, skipping, chain printing, wrinkling, violent edge, etc., the result should be stopped in time. Only after the inspector confirms can the machine be re-rolled.
5. When the rewinding operation is running, the host must be at the console, and must not leave at will to prevent accidents. Transport
The speed of lifting and lowering is slow, and the speed of the vehicle cannot exceed the prescribed limit.
6. When loading the paper core tube, it is necessary to select the paper core with the same outer diameter and the length specification in line with the quality standard.
The installation of the cylinder requires a large deviation of the outer diameter and needs to be replaced.

Rewinder mechanical structure and control process ---

 

Second, the main structure of the winder

2.3 Rolling Department
1. Stretching device
The stretching device of the rewinder is set to keep the paper web slit after slitting. In some paper cutting knives, the stretcher is also used. The main function is to eliminate the texture and slack of the paper web. Mainly, it can maintain the good operation of slitting. There are three types of stretchers that we often use today: D-shaped stretches, curved rollers, and Z-type double-bar stretchers.
2, support roller
The backup roll is mainly used to support the paper roll, which is composed of a controlled cast iron roll or a general tube roll. The roller body is mainly cast iron pipe and steel pipe, and its diameter is usually 400-700 mm or more according to the width of the winder. The center-to-center ratio between the rolls of the backup roll should be greater than the roll diameter. Only at such a distance, the roll core does not get caught in the middle of the roll when the support roll begins to curl.
When the winder is running at high speed, in order to avoid vibration during high-speed operation, the design of the backup roller must be minimal when supporting the paper roll. The radius is a function expression of the speed and width of the winder, mainly by allowable The critical speed and the degree of winding are determined because at this time the diameter of the backup roll has less chance of producing a defect in the roll hardness than the small diameter support roll. When coiling coated paper or very thin paper, we should consider using a larger diameter backup roll. On a rewinder with a small width, we generally use a 600mm roll diameter.
