Paper slitter rewinder machine with shaftless loading type can Maximum unwinding diameter 1500mm raw material, width 1100-3200mm can be customized according to the customer's raw material width. machine shaftless feeding form can be placed paper tube inner diameter of 3-6 inches of paper roll raw materials.

 

Unwinding configuration U-shaped automatic deviation correction control system spacing is 4 cm. The function of this control system is to prevent material deviation or displacement during unwinding and to maintain the stability of the material.

 

Working process: the cutting tool can be a round knife or an air knife, and the cutting width and cutting mode can be realized by adjusting the position and setting of the cutting tool. The slitting part is moveable so that it is close to the rewinding part and moves backward with the increase of the rewinding diameter to ensure that the slitting part is close to the rewinding part.

 

11 KW servo motor is used to drive the reel, and the tension is automatically controlled by PLC, so that multiple strips will not be affected by the thickness of the material. The end face of the reel is flat, and the leveling method is selected by pneumatic pressing roller and self-weight pressing roller. The tightness of the inner and outer layers of the finished coil can be controlled, and the spiral winding method is adopted. As the winding diameter increases, PLC will automatically reduce the speed of the winding servo motor.

The rewinding inflatable shaft can support unilateral opening and bilateral opening. The machine is also equipped with a pneumatic blanking device and a pressing roller group to prevent slack after cutting off the paper after rewinding a roll.

 

Finally, a larger power suction system is used to absorb the waste side material

 

1. The working process of round knife:

A round knife is a rotary tool, usually composed of a blade and a tool shaft. The blade is usually round or semicircular and is mounted on the knife shaft.

During the working process of the round knife, the tool shaft will be rotated by power sources such as the motor. The rotation speed can be adjusted as needed.

When the cutting material enters the cutting area, the blade of the circular knife will come into contact with the material and rotate under the drive of the knife shaft. The sharp edge of the blade cuts off the cutting material.

-the material needs to be stable in the process of cutting with a circular knife and controlled by tension control equipment to obtain accurate cutting results.

-cutting width and cutting speed can usually be controlled by adjusting the position of the blade and adjusting the rotation speed.

 

2. The working process of air knife:

An air knife is a tool that uses airflow energy for cutting. It usually consists of a nozzle and an air source.

During the working process of the air knife, the air source will provide high pressure gas (such as compressed air) and accelerate the air flow through the nozzle.

-the accelerated high-speed airflow forms a narrow airflow ray through the outlet of the nozzle, which has a high impact force.

-the material to be cut is placed in the cutting area of the air knife, and the material is cut off by the impact of high-speed air flow.

The air knife can control the cutting strength and width by adjusting the pressure of the air source and controlling the nozzle diameter of the air flow.

-Air knife can be used to cut soft materials (such as paper, cloth, etc.) and some thin film materials.

 

It should be noted that when using a circular knife or air knife, follow the relevant safety operating procedures, including correctly fixing the tool, setting appropriate cutting parameters, wearing personal protective equipment, etc., in order to ensure the safety of the operator. And select the appropriate cutting tools and technology according to the characteristics of the material and cutting requirements.
