Problems solved by technology

[0014] If the tension is insufficient, the base paper will drift during operation, and the finished paper will be wrinkled after slitting and rewinding; if the tension is too high, the base paper will be easily broken, resulting in more broken ends of the finished paper after rewinding
[0015] 3) Since the tension adjustment device adopts mechanical transmission, the mechanical coaxial transmission wears seriously and requires frequent maintenance

Embodiment

[0041] 1) The main inverter is the power drive of the whole machine, the 1# slave inverter is the paper feeding power of the 1# paper rack, the 2# slave inverter is the paper feeding power of the 2# paper rack, the touch screen is used for parameter correction, and the PLC is used for The system control and the encoder are used for data feedback. This configuration makes the electrical control of the equipment in a complete closed-loop system, thereby fully eliminating the problem of over-tension and under-tension.

[0042] 2) Job requirements:

[0043] Tension control refers to the ability to permanently control the tension of the base paper when it is conveyed on the equipment. This control must remain effective for any speed at which the machine operates, including acceleration, deceleration, and constant speed of the machine. Even in the case of emergency shutdown, it should be able to ensure that the cut objects are not damaged. The purpose of tension control can be ach...

Abstract

The invention relates to a synchronous speed regulating device for a slitting and rewinding machine of a paper disc to keep tension balancing of big volumes and small volumes in the slitting and rewinding machine of paper disc. The synchronous speed regulation device for the slitting and rewinding machine of the paper disc comprises a PLC, a regulating assembly of big volume and a regulating assembly of small volume. The PLC is connected to the regulating assembly of big volume and the regulating assembly of small volume correspondingly; when regulating, the regulating assembly of big volume is connected to the regulating assembly of small volume to achieve torque and speed of an electric motor of the big volume and an electric motor of small volume correspondingly; and according to the torque and speed of an electric motor of the big volume and an electric motor of small volume, the PLC regulating through Closed-loop the torque and speed of an electric motor of the big volume and an electric motor of small volume, thus tension balancing of big volumes and small volumes can be kept. Compared with the prior art, the synchronous speed regulation device for the slitting and rewinding machine of the paper disc has the advantages of being accurate in tension control, longer in service life, and the like.

Description

technical field [0001] The invention relates to a speed regulating device, in particular to a synchronous speed regulating device of a coil paper slitting and rewinding machine. Background technique [0002] The paper slitting and rewinding machine is used to produce small toilet paper. With the improvement of facilities in public places, it is widely used in toilets in public places such as hotels and office buildings. People's recognition and demand for small paper is increasing day by day. Modern small-pan paper is not only required to be hygienic and clean, but also has requirements for the shape and thickness of the paper. At the same time, it is required that the appearance of the produced paper products should be neat and the edges of the paper should not be frayed. [0003] The operation process of the existing coil paper slitting and rewinding machine: [0004] Raw material loading (pneumatic feeding) - pneumatic feeding - manual tension adjustment device - embossi...
