Rewinding Machine safety operation guide - 

Sixth, change the specification operation:
1. Stop the winder and lift the round knife and tighten the bolts on the base of the round knife.
2. Move the base of the circular knife holder and measure the distance between two adjacent circular cutters with a tape measure to make it conform to
Paper specification requirements.
3. Fix the base of the round knife holder, tighten the bolts, and measure the specifications once again.
Dynamic rewinding (contact angle, tightness, depth).

Rewinding Machine operation safety regulations - 

Second, the operation steps:

4, traction paper head, start switch paper, the paper passing through the following parts: curved rod - towel press paper knife in front of punching knife - punching knife - curved rod - felt paper stick - winding wheel (the whole process It is necessary to use jog feed or slow speed. When entering the punching knife, it is strictly prohibited to twist the paper into one or more layers, and pay attention to safety);
5. Set the number of production sections according to product specifications;
6. Take a bundle of paper tubes into the paper tube push-up rack of the machine, spread the paper tube, take one into the middle of the two winding wheels, (and then press the embossing stick), and slowly rotate the machine. Rewinding (the ropes bundled with paper tubes should be placed in accordance with the regulations, and should not be randomly placed);

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.
