Description

High-speed circular knife die-cutting machine

Technical Field

The utility model relates to the technical field of printing and packaging, in particular to a high-speed circular knife die-cutting machine.

Background

The circular knife die-cutting machine is used for die-cutting production of film materials such as label paper, self-adhesive paper and the like. In the prior domestic circular knife die-cutting machine, the front and back die-cutting work is realized, the production speed is generally not higher than 100 meters per minute, namely the die-cutting production with the speed of more than 100 meters per minute is difficult to be finished; in addition, after the temporary shutdown or the work shutdown, the tension of the film materials such as the label paper, the self-adhesive paper and the like can be changed, so that the front and back die cutting positions of the film materials are changed, and the film materials are required to be adjusted when the machine is restarted every time, which is very inconvenient.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide the high-speed circular knife die cutting machine which can realize high-speed die cutting, simultaneously ensure that the die cutting position is unchanged during start-up and shutdown and improve the die cutting production speed.

The utility model is completed by adopting the following technical scheme:

high-speed circular knife cross cutting machine, including blowing part, cross cutting part and rolling part, its characterized in that: the cross cutting part comprises two sets of the same circle mould cutting groups that bilateral symmetry set up, every group circle mould cutting group is including cross cutting roller and rotor, the cross cutting roller is rotatable to be located on the cross cutting roller seat, the rotor is rotatable to be located on the rotor seat, cross cutting roller seat, the rotor seat can be located in the cross cutting frame by the horizontal slip, one side that the rotor was kept away from to the cross cutting roller is equipped with the bottom roll, the bottom roll is rotatable to be located on the intermediate lamella, the intermediate lamella is fixed mounting in the cross cutting frame, one side that the rotor kept away from the cross cutting roller is equipped with the pinch roller, the pinch roller is promoted by the pinch roller cylinder and is carried out the activity about.

A traction component and a deviation rectifying component are arranged between the die cutting component and the discharging component, and a waste collecting component is arranged above the die cutting component.

And a film material locking component is arranged between the die cutting component and the winding component.

The film material locking part comprises a fixed roller and a movable roller, and the movable roller is pushed by a movable roller cylinder.

According to the technical scheme, when the high-speed circular knife die-cutting machine works, the pinch roller cylinder pushes the pinch roller to enable the knife roll, the die-cutting roll and the bottom roll to be in pressing contact, the bottom roll supports the die-cutting roll from the rear side direction to prevent the die-cutting roll from deforming so as to ensure reliable attachment of the knife roll and the die-cutting roll, and therefore the rigidity of the whole die-cutting part is high, the attachment degree is good, high-speed die-cutting production is achieved, and the die-cutting production speed can reach 300 m/min. In addition, when the machine is stopped temporarily or is stopped during working, the label paper or the adhesive sticker paper is pressed on the fixed roller through the action of the movable roller, the tension of the film material is prevented from changing after the machine is stopped, the tension of the film material is kept, the front die cutting position and the rear die cutting position of the film material cannot change, the machine is restarted every time, the die cutting position does not need to be readjusted, the machine is very convenient, and the production efficiency is improved.

Drawings

The utility model has the following drawings:

figure 1 is a perspective view of the present invention,

fig. 2 is a longitudinal sectional view of fig. 1.

Detailed Description

As shown in the figure, the high-speed circular knife die-cutting machine comprises a discharging component 1, a die-cutting component and a winding component 13, wherein the die-cutting component is composed of two groups of circular die-cutting groups with the same structure which are arranged in a bilateral symmetry mode, each group of circular die-cutting groups comprises a die-cutting roller 8 and a knife roller 9, the die-cutting rollers 8 are rotatably arranged on a die-cutting roller seat 5, the knife rollers 9 are rotatably arranged on a knife roller seat 4, the die-cutting roller seats 5 and the knife roller seats 4 can be arranged on a die-cutting rack 16 in a left-right sliding mode through sliders and linear sliding rails, a bottom roller 6 is arranged on one side, far away from the knife rollers, of the die-cutting rollers 8, the bottom roller 6 is rotatably arranged on an intermediate plate 7, the intermediate plate 7 is fixedly arranged on the die-cutting rack 16, pinch rollers 10 are arranged on one side, far away from the die-cutting rollers 9, the pinch rollers 10 are pushed by pinch roller cylinders to move left and right, and the pinch rollers abut against two ends of the knife rollers during working. The drawing part 3 and the deviation rectifying part 2 are arranged between the die cutting part and the discharging part 1, the waste collecting part 11 is arranged above the die cutting part, the film material locking part is arranged between the die cutting part and the winding part 13 and comprises a fixed roller 14 and a movable roller 15, the fixed roller 14 is fixedly installed, and the movable roller 15 is pushed by a movable roller cylinder.

The utility model is produced by high-speed circular die cutting: the film material gets off from the discharging part 1, reaches the die cutting part after being rectified by the rectifying part 2 and pulled by the pulling part 3, at the die cutting part, the right round die cutting group performs front die cutting on the film material, the generated die cutting waste material is coiled by the waste collecting part 11, the film material subjected to front die cutting enters the left round die cutting group, the left round die cutting group performs back die cutting on the film material, the film material subjected to front and back die cutting reaches the coiling part 13 through the film material locking part and the rear rectifying part 12, and the coiling part 13 performs coiling to complete high-speed round die cutting production.
