Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing, in particular to a paperboard machine adopting gravure printing. Background Art

[0002] Cardboard inside photo frames is essential for creating a beautiful everyday environment and possessing artistic effects and appeal. Cardboard cutting machines are essential equipment for automated cardboard processing. They are two-and-a-half-axis CNC devices, and their functionality and level of automation are hallmarks of the cardboard production industry's production capabilities. The knife holder is the core component of a cardboard cutting machine and one of its most complex components. The complexity and applicability of its functions have a crucial impact on the processing range and reliability of the entire cardboard cutting machine. Achieving different bevel blade angles for cutting cardboard is one of the primary factors in expanding the processing range of cardboard cutting machines. This is an increasingly pressing market need, making variable bevel blade angles an indispensable key technology. Its ultimate goal is to expand the processing range and artistic effects of cardboard cutting, while meeting the market's growing demand for individuality. A Chinese patent discloses a paper jam machine (authorization announcement number CN219882600U). This patented technology discloses a paper jam machine, including a fixed frame for installation and a table for fixing paper jams, and a longitudinal moving component and a transverse moving component for adjusting the position. The table is installed at the bottom of the fixed frame, and the upper side of the table is installed with a longitudinal moving component and a transverse moving component. It also includes a cutting mechanism for cutting paper jams and a lifting mechanism for driving the cutting mechanism to move up and down. The lifting mechanism is installed at the movable end of the transverse moving component, and the cutting mechanism is installed at the bottom of the lifting mechanism. A vibration mechanism for improving the cutting effect is installed between the side of the cutting mechanism and the lifting mechanism. The utility model facilitates cutting paper jams of different requirements at different angles by adjusting the angle of the cutter head, and cooperates with the slight vibration generated during lifting and lowering to make it easier to insert the blade into the paper jam, thereby improving the cutting effect. This patented technology solves the current problem in the field of paper cutting where a paper cutting machine with an inclined blade head is used. Because the blade is already inclined when it descends, the force direction is not concentrated when it contacts the paper, which can easily cause the blade to tilt too much or the paper to be too hard to cut, affecting the processing effect.

A circulation pump 206 is connected to the outer side of the circulation pipe 205, and the water pumping end of the circulation pump 206 is connected to the inside of the flowing bottom material box 202;

[0037] A locking through slot 212 is formed through the inner wall of the arc-shaped top frame 211, and a through slot locking block 216 is movably provided inside the locking through slot 212, and a locking bolt 217 is installed in the through slot locking block 216 with a spiral transmission; a contact scraper 208 is slidably installed on the top side of the arc-shaped top material box 203, one end of the contact scraper 208 movably passes through the outside of the arc-shaped top material box 203, and a plurality of synchronous cylinders 209 are installed between the arc-shaped top material box 203; the structures of the paper jam conveying structure 1 3 and the paper jam conveying structure 2 4 are the same;

[0038] The paper jam conveying structure 1 3 includes a mounting frame 301 fixedly mounted on the load-bearing plate seat 201, with a plurality of auxiliary rollers 302 rotatably mounted inside the mounting frame 301; and a main roller 1 303 and a main roller 2 306 rotatably mounted inside the mounting frame 301. One end of the main roller 1 303 rotatably penetrates the outer wall of the mounting frame 301 and is fixedly mounted with a first spur gear 304. The first spur gear 304 is meshed with a second spur gear 307, and the second spur gear 307 is fixedly mounted on the outer wall of the main roller 2 306.

[0039] The first spur gear 304 is connected to the second servo motor 305; a dryer 207 is provided above the contact scraper 208, and the dryer 207 is installed on the top of the arc-shaped top material box 203; a controller 5 is installed on the outer wall of the paper machine body 1.

[0040] According to the above embodiment, the working principle of the present invention is:

[0041] When the jammed paper is discharged from the jammed paper outlet of the paper machine body 1, it is first transported to the gravure printing mechanism 2 through the jammed paper conveying structure 1 3 for gravure printing, and then discharged through the jammed paper conveying structure 2 4;

[0042] The paper transport mechanism 1 starts the servo motor 2 305, which drives the first spur gear 304 to rotate. The rotating first spur gear 304 engages and drives the second spur gear 307 to rotate, causing the main roller 1 303 and the main roller 2 306 to rotate in opposite directions at the same time, actively moving the paper to the surface of the gravure brush roller 214 for gravure printing.

[0043] During gravure printing, the servo motor 1 219 is started, which drives the gear 2 218 to rotate. The gear 218 rotates to engage the gear 1 215, so that the gear 1 215 drives the gravure brush roller 214 to roll on the bottom of the cardboard, and the ink in the pattern groove is printed on the cardboard.

[0044] When the gravure brush roller 214 rotates, the bottom passes through the arc-shaped top material box 203 to load the ink. Then, the gravure brush roller 214 with ink passes through the contact scraper 208, which scrapes the ink left on the surface of the gravure brush roller 214 and leaves it in the arc-shaped top material box 203. At the same time, the ink inside the arc-shaped top material box 203 flows into the fluid bottom material box 202 through the slot at the lower end, and then passes through the circulation pump 206. The circulation pump 206 is started to circulate the ink inside the fluid bottom material box 202 through the circulation pipe 205 and the circulation top groove 204 and is discharged into the arc-shaped top material box 203 to ensure the fluidity of the ink and prevent it from solidifying.

[0045] When the gravure brush roller 214 is replaced, it is disassembled manually by taking the locking bolt 217 of the through-slot locking block 216, and then the through-slot locking block 216 is manually removed to disassemble and replace the gravure brush roller 214;

[0046] After the cardboard is printed with ink by the gravure brush roller 214, it passes through the top of the dryer 207. The dryer 207 dries the printed ink, and then the cardboard is discharged through the cardboard conveying structure 24, thus completing the gravure printing process of the cardboard machine.

[0047] The synchronous cylinder 209 is used to adjust the distance between the contact scraper 208 and the gravure brush roller 214.

[0048] In the present invention, unless otherwise clearly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0049] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.
