Rewinder mechanical structure and control process ---

As the last process in the papermaking industry, the winder is the fastest running machinery in papermaking machinery. Its speed can reach 1500~1800m/min or even the speed can reach 3000m/min or more. The winder is in the papermaking industry. The important role that can not be ignored, the paper roll from the paper machine must be rewinded by the winder to get the finished paper roll we need, and the quality of the finished paper roll is not only determined by the paper machine, The role of the winder is also of particular importance.

 

The working principle of the winder is to install the large paper roll produced from the paper machine on the paper exit frame of the winder. In order to maintain a certain tension of the paper web, the brake device must be installed on the paper return frame. A brake motor is installed on the paper exit frame. If the paper breaks during the rewinding process, the brake device can also brake quickly to reduce paper loss. The web is cut to the width we need by the slitting roller, the paper guide roller and the winder slitting mechanism, and then re-rolled into a paper roll according to the required tightness and the diameter of the finished paper roll. The main structural parameters of the winder are the width of the paper roll that can be rewinded, the maximum speed that the rewinding machine can reach, the quality of the finished paper roll, the maximum diameter of the ejecting roll and the roll paper, and the method of cutting the paper.

 

There are many types of rewinders, and other devices can be equipped in the rewinder as needed to become a joint machine. The rewinder can basically be divided into the following five types: upper paper rewinder, lower paper rewinder, single roll rewinder, special rewinder and thin paper rewinder. Since the research object of this subject is mainly for the lower threading rewinding machine, the introduction and explanation of the double bottom roller lowering paper rewinding machine will be given.

Guolian High Speed ??Slitting Rewinder Technical Description ---

The specific technical structure is described as follows:

2. Paper cutting department:
It is mainly composed of independent frame, guiding paper-feeding roller, segmented and extended arc roller device, front and rear segment guide roller, bottom knife device, round knife device and paper suction fan.
The frame is welded by steel plates and is heavy and sturdy, completely independent of the take-up frame, avoiding the effects of possible vibration on the paper cut.
Guided paper roller, diameter Φ700mm, material Q235, directly driven by motor, chrome-plated surface, hydraulic disc brake and vertical adjustment device, can be adjusted along the scale with worm gear system to adjust the tension of the paper web, adjustment range It is ±25mm. The large diameter guide rollers also facilitate smooth and high speed operation of the equipment and paper web. The bottom knife device, the round knife device and the front and rear segment guide rollers form a paper cutting platform to ensure that the width direction of the paper cutting is even and even. There are 6 sets of cutters, top knife φ180mm, bottom knife φ200mm, each bottom knife is driven by a variable frequency motor, the cutter is automatically positioned, and the cutting servo width is automatically adjusted by the control servo system. The entire slitting system assembly (including tool holders, guide rails, etc.) is imported from abroad to ensure its stability and reliability. The segment guide roller before and after the cutter has a diameter of φ198mm and a roller material Q235, which is divided into 5 sections. Each side of the cutter is equipped with SKF bearings. The surface of the roller body is grooved and the surface is chrome-plated. The circular knife device is composed of a cylinder, a sliding seat and a round knife, and is fixed on the circular beam beam guide rail. The feeding knife and the knife are controlled by the cylinder. After the starting, the two sides of the knife start to cut the paper edge, and the other round knife is given by the operator. After the command is fed, when the paper breaks, the air source of the middle circular knife is automatically cut off by the main control command and automatically raised. There is a web stabilizer plate on each side of the knife to guide the paper edge.
      Before the paper cutting table, a set of segmented stretching roller system is installed. The diameter of the stretching roller is φ198mm, the material of the roller body is Q235, and the surface is chrome-plated. The total length is 19 segments. The curvature of the multi-stage roller can be adjusted before and after the hand wheel to ensure the paper web. smooth.
      The suction paper edge device on both sides of the longitudinal cutter uses a special fan to break the paper edge, which makes the suction effect better, and is also beneficial to the next processing of the waste paper edge. Fan motor power 37KW air volume 11000m3 / h.
