Description

Technical Field

[0001] This utility model belongs to the field of printing machinery design and manufacturing technology, and more specifically, it relates to a ring-shaped pressure device for a water-based ink printing machine. Background Technology

[0002] In the packaging and printing industry, water-based ink printing machines are key equipment for producing corrugated cardboard boxes and other packaging products. Among them, the creasing process is an important step to ensure that the printed cardboard can be accurately bent and shaped at a predetermined position. The ring creasing device is the core component to realize this process. When the ring creasing device is in use, the power source generally drives the ring transmission system to operate, which drives the creasing components to move in a cycle. When the printed cardboard is transported to the working area of ​​the ring creasing device, the creasing components come into contact with the cardboard in turn, and under pressure, creases are pressed into the surface of the cardboard.

[0003] The existing application number is CN201520095818.6, which describes a pre-pressing line device for slotting or die-cutting in a printing press. The device includes a toothed pre-pressing wheel mounted on a pre-pressing wheel seat and a corresponding pre-pressing pair of wheels. The toothed pre-pressing wheel has a helical tooth shape, and the teeth are shaped like a drum with a central bulge. This pre-pressing line device for slotting or die-cutting in a printing press solves the problem of insufficient squareness of cartons, ensuring that the cartons are always folded along the pressing lines during folding without deviation.

[0004] Based on the above, when using the existing circular creasing device of the water-based ink printing machine, the thickness varies due to errors in the cardboard processing, the thickness tolerance of the cardboard fluctuates, and there are also uneven thicknesses within the same batch. Moreover, the existing circular creasing devices of the water-based ink printing machine are mostly fixed structures, and the pressure is uniform during creasing, which easily leads to inconsistent creasing depths, affecting the creasing and corrugated carton production quality.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a dynamic adjustment mechanism. The cardboard passes through a pressure sensor, which transmits a signal to a PLC controller. The PLC controller controls the adjustment drive push rod. When the pressure is too high, the push rod moves upward, causing the adjustment connecting slider to move upward. This upward movement of the slider causes a set of sprocket and chain crease pressing components above to move upward. At this point, the distance between the two sets of sprocket and chain crease pressing components increases, reducing the pressure on the cardboard. This achieves dynamic adjustment of the cardboard pressure during crease pressing, ensuring consistent crease pressure and depth, thus improving the processing quality of corrugated boxes. Simultaneously, a vacuum cleaner is activated, transmitting negative suction through a cleaning connecting pipe to a cleaning suction component. This component cleans paper scraps and dust from the surface of the crease knife, further improving crease quality.

[0015] This invention, through the setting of a creasing drive mechanism, activates a creasing drive motor, which drives a creasing drive gear to rotate. This gear, in turn, drives a creasing transmission gear, which in turn drives a creasing drive worm gear. The worm gear, in turn, drives a creasing drive worm wheel, which in turn drives a sprocket and chain creasing component. This sprocket and chain creasing component then drives a creasing knife to creasing the cardboard. Simultaneously, a keyed connection between the upper set of creasing transmission gears and the upper set of creasing drive worm gears allows the entire creasing device to be adjusted during the creasing process, avoiding machine downtime for adjustments and improving carton production efficiency.

Multiple sets of indentation knives 4 are provided, each fixedly connected to the outer side of the chain structure of the sprocket and chain creasing component 3. The creasing drive box 5 is fixedly connected to the left rear of the creasing mounting plate 1. The adjustment drive push rod 6 is fixedly connected to the middle rear of the creasing mounting plate 1. The dynamic adjustment mechanism is located on the outer side of the creasing mounting plate 1.

[0027] The dynamic adjustment mechanism includes a cleaning adsorption component 101 and a cleaning connecting pipe 102.
