Embodiment
[0016] The structure of the transmission part of the general rewinder at home and abroad is as follows: figure 1 As shown, it includes the unwinding roller 1, the front bottom roller 2, the rear bottom roller 3, the arc rollers 6, 7, 8, the pressure roller 5 arranged on the front bottom roller 2 and the rear bottom roller 3, and the introduction roller 4 And paper cutter 9: unwinding roller 1 assists unwinding paper roll 11, and controls torque current to adjust tension; front bottom roller 2 and rear bottom roller 3 assist in winding the paper shaft; arc roller 6 wraps the paper web Open to prevent paper from wrinkling; pressure roller 5 increases the hardness and tightness of roll paper 12, and prevents the paper roll from flying at high speed; lead-in roller 4 assists in the introduction of the paper head when leading the paper, and assists in generating tension during operation; The paper knife 9 is rotated at a higher linear speed than the paper web 10 to slit the paper w...

The invention relates to a transmission control flow for a rewinding machine and discloses a transmission control flow for a papermaking rewinding machine, comprising the following steps: controlling an unwinding roll (1), a front bed roll (2), a rear bed roll (3), curved rolls (6,7,8), a dancer roll (5) arranged on a paper roll (12), a feed roll (4) and a paper cutter (9); carrying out transmission control by adopting a control state conversion mode; and dividing the operation process and security protection function of rewinding machine transmission control into an operational control stateand a protective control state. The invention is characterized in that a modular design is adopted aiming at the control flow of the traditional papermaking rewinding machine, thus improving the generality of the control flow; multiple control states are set, thus control information quantity is increased, the operating steps are simplified, maintenance and diagnosis are convenient, the operatingperiod is shortened, and the production efficiency is improved; and various stop settings are adopted, thus the safety of the papermaking rewinding machine is protected, unnecessary paper-breaking stop processes are avoided at the same time, and the maintenance time is saved.
Description
technical field [0001] The invention relates to the transmission control flow of a rewinder, in particular to the control of the transmission flow mainly applied to a papermaking rewinder. Background technique [0002] As the competition in the papermaking industry continues to increase, the production scale of papermaking enterprises is also expanding, and the production equipment introduced is becoming more and more advanced. At present, the maximum speed of the mainstream paper machine is generally 800-1000 m / min, and the maximum operating speed of the rewinder is required to be 2.5-3 times the speed of the paper machine, which is 2000-3000 m / min. Because the operation process of the rewinder is different from the continuous operation of the paper machine, it is an intermittent operation, which is divided into multiple steps such as paper threading, speed up, operation, speed down and roll change. The actual running time at the highest speed only takes up to 1 / 2 or even ...
