Abstract
The utility model relates to a rotary die-cutting device capable of eliminating the transmission clearance. The utility model is characterized in that a friction part is arranged additionally on the rotary die-cutting device, thereby, the drive moment of the motor to the die-cutting knife roller is more than zero in normal condition; the action surfaces of the gears in each level between the motor and the die-cutting knife roller do not change; thus the influence of the transmission clearance on the transmission precision in the die-cutting device is eliminated.
Description
Affiliated technical field the utility model relates to a kind of rotating die cutting device, the especially a kind of rotating die cutting device that can eliminate drive gap.
Background technology
Rotating die cutting device uses in a large number in printing, packing and adhesive article processing and other fields, and power-equipments such as ac motor, dc motor and servomotor are given rotating mould cutting roller transmission of power by mechanical parts such as gear, synchronous band, shaft coupling, reductor, leading screws.Usually between the gear or have the gap between the drive disk assembly, when rotating die cutting device is in frequent acceleration and deceleration state, or the tractive force of machined material and brake force is when changing, and the field of conjugate action of gear or other drive disk assembly can change, and drive gap brings adverse effect to transmission accuracy.Rotating die cutting device with the servomotor drive is an example, servomotor passes through reductor, shaft coupling drives the smooth roll rotation, gear is arranged on the smooth roll, gear on the smooth roll is passed to gear on the die cutter roller to power, die cutter roller and smooth roll surface are pressed close to and are done relative rotary motion, need the strip material of processing between die cutter roller and smooth roll, to travel forward, strip material is become satisfactory shape by rolling cut, when servomotor is in frequent acceleration-deceleration, or strip material on these rotating die cutting device both sides forward pulling force and pulling force backward when changing, the field of conjugate action between the gear can change, gear clearance can be brought influence to transmission accuracy, thereby causes the cross cutting error of final products to become big.
Summary of the invention
Drive gap is to the influence of transmission accuracy in the rotating die cutting device in order to overcome, and the utility model provides a kind of rotating die cutting device that can eliminate drive gap, and this device is by eliminating the influence of drive gap in terminate load additional friction moment.
The technical scheme that its technical problem that solves the utility model adopts is: rotating die cutting device is by motor, shaft coupling, gear, smooth roll, die cutter roller, transition roller, mechanical parts such as rubber roll are formed, on rotating die cutting device, increase friction means, friction means can be attached to the spindle nose of die cutter roller, friction means also can act on the surface of die cutter roller, it is also passable to increase a friction roller again in the back of die cutter roller, in the end the one-level driven roll is (as transition roller, traditional method of indicating the pronunciation of a Chinese character roller, rubber rolls etc.) going up the additional friction parts equally can, like this motor to the driving moment of die cutter roller under normal operation all greater than zero, motor just can not change to gear meshing faces at different levels between the die cutter roller, because of causing the gears engaged face, effect of inertia changes when avoiding motor deceleration, avoid the excessive gears engaged face that causes of the suffered pulling force forward of processed band to change, so just eliminated in the rotating die cutting device drive gap to the influence of transmission accuracy, friction means can be a mechanical type, as friction plate, it also can be electric, as magnetic powder brake, the electric current of the pressure of adjusting friction plate or change magnetic powder brake just can change the size of additional friction power.
The invention has the beneficial effects as follows by drive gap in the additional friction parts elimination rotating die cutting device the influence of transmission accuracy, because the technical measures that this utility model is taked just get final product at the die cutter roller side increase friction means of rotating die cutting device, simple possible, it is convenient to realize.
