Description

Technical Field

[0001] The invention relates to the technical field of inkjet coding and die-cutting, and in particular to an inkjet coding and die-cutting device for printing and packaging. Background Art

[0002] Printing packaging mainly refers to packaging materials that have been printed with patterns or texts. The coding die-cutting device is an all-in-one machine used to die-cut and code packaging such as packaging bags. It does not need to be transported to the coding equipment for coding processing after the printing and packaging die-cutting, which improves the production and processing efficiency. The equipment generally includes a loading device, a printing device, a die-cutting device and a winding device.

[0003] When existing equipment performs coding and die-cutting on printed packaging such as plastic film rolls or paper rolls, in order to ensure stability during coding and die-cutting, the printed packaging is tensioned by a tensioning structure. For example, the invention patent with authorization announcement number CN110091583B discloses a coding device for a packaging bag printing and die-cutting integrated machine and an installation method thereof. The tensioning mechanism is used to keep the plastic film (or paper) in a tensioned state when it is transferred between the winding device and the die-cutting device, thereby avoiding wrinkles in the plastic bag (or paper) and ensuring the coding effect of the coding machine.

[0004] However, this invention patent still has corresponding defects: in the process of printing and packaging such as plastic film being pulled and transported to the die-cutting or coding area, due to the poor stability of the plastic film during transportation, although the plastic film can be tightened by the tensioning mechanism, its edges are still prone to curling and overlapping with the adjacent areas on the plastic film, resulting in the plastic film being affected in subsequent die-cutting, coding and winding processes, such as affecting the die-cutting effect and causing uneven incisions, affecting the actual coding effect or the coding area, etc., and causing the edges of the plastic film to overlap when winding, causing the overlapping area of ​​the plastic film to deform when winding, and affecting the quality of winding.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 7As shown, the present invention provides a coding and die-cutting device for printing and packaging, comprising a bracket 1, on which a reeling mechanism 2 for releasing a rolled printed package, a coding mechanism 3 for coding the printed package, a die-cutting mechanism 4 for die-cutting the printed package, an elastic tensioning mechanism 7 and a reeling mechanism 5 for reeling in the printed package that has been coded are arranged in sequence along a straight line, a vibration and leveling mechanism 6 located on the bracket 1 is arranged between the reeling mechanism 2 and the coding mechanism 3, and the vibration and leveling mechanism 6 generates vibration and levels the printed package when the printed package passes through, and the elastic tensioning mechanism 7 is used to tension the printed package in motion.

[0030] When the present application is actually used, a rolled printed package (such as a rolled plastic film, etc.) is placed on the unwinding mechanism 2, and one end of the printed package passes through the vibration leveling mechanism 6, the coding mechanism 3, the die-cutting mechanism 4, the elastic tensioning mechanism 7 and the winding mechanism 5 in sequence, and the coding and die-cutting processing of the printed package are completed in sequence, so that the printed package can complete coding and die-cutting at the same time after one processing, thereby improving production efficiency.

[0031] During the transportation of printed packages, the vibration smoothing mechanism 6 vibrates the printed packages passing by and smoothes them during the vibration process, so that the curled and overlapping parts at the edges of the printed packages gradually recover after the vibration and are smoothed by the vibration smoothing mechanism 6, so that the printed packages entering the coding mechanism 3 and the die-cutting mechanism 4 are flat and have no curled and overlapping parts, thereby improving the coding and die-cutting quality of the printed packages and avoiding problems such as overlapping coding areas and uneven die-cutting edges due to curling and overlapping at the edges of the printed packages.

[0032] In this embodiment, the unwinding mechanism 2, the coding mechanism 3, the die-cutting mechanism 4 and the rewinding mechanism 5 are all existing technologies. For example, the unwinding mechanism can be a rotating roller that can fix the rolled printed packaging and can rotate. The rewinding mechanism 5 can be a device driven by a driving device that can rotate and fix the rolled printed packaging. The coding mechanism 3 and the die-cutting mechanism 4 can refer to the existing equipment for coding and die-cutting. The technical principles of the above parts will not be elaborated in detail here.

[0033] Furthermore, a vibration smoothing mechanism 6 may be provided between the elastic tensioning mechanism 7 and the winding mechanism 5 to ensure the winding quality of the winding mechanism 5 .

[0034] The vibration leveling mechanism 6 includes two groups of supporting side plates 601 arranged on the bracket 1, and the tops of the two groups of supporting side plates 601 are fixedly connected with a supporting top plate 623. The bottom of the supporting top plate 623 is provided with an elastic supporting structure 602, a toggle structure 603 and a vibration structure 604. The toggle structure 603 is used to toggle the vibration structure 604 to reciprocate in the vertical direction. The vibration structure 604 is used to alternately vibrate the printed package. The elastic supporting structure 602 is located on both sides of the vibration structure 604 and is used to support the printed package.

[0035] The vibration leveling mechanism 6 supports the mounting support top plate 623 through two groups of support side plates 601 , and together with the support top plate 623 , provides mounting support for the elastic support structure 602 , the paddle structure 603 and the vibration structure 604 .

[0036] The elastic support structure 602 contacts and supports the printed packages on both sides of the vibration structure 604. The vibration structure 604 vibrates when driven by the driving structure 603, so that the printed packages in contact with the bottom of the vibration structure 604 also vibrate. During the vibration, the edges of the printed packages shake due to vibration, so that the curled and overlapping parts gradually unfold, thereby eliminating the curled and overlapping parts at the edges of the printed packages. The elastic support structure 602 ensures that the printed packages are always in a taut state during the vibration process through its own elastic deformation, thereby preventing the edges of the printed packages that have corrected the curled and overlapping problems from curling and overlapping again due to vibration.

[0037] The elastic support structure 602 includes two fixed rod groups fixedly set on the support top plate 623, and the two fixed rod groups are located on both sides of the vibration structure 604, each fixed rod group includes two fixed rods 605 arranged on the support top plate 623, each fixed rod 605 is slidably sleeved with a sliding sleeve 606, and the corresponding two sliding sleeves 606 are rotatably connected with a support roller 607, each fixed rod 605 is slidably sleeved with a spring 608, and the two ends of the spring 608 are respectively against the support top plate 623 and the sliding sleeve 606, and each fixed rod 605 is fixedly provided with a limit block for limiting the maximum sliding distance of the sliding sleeve 606.

[0038] The two support rollers 607 are respectively against the printed packaging parts located on both sides of the vibration structure 604, which not only ensures the normal transportation of the printed packaging, but also the spring 608 is in a compressed state at this time. The elastic force of the spring 608 presses the sliding sleeve 606, so that the support rollers 607 press the printed packaging to tension the printed packaging, so that the printed packaging on both sides of the vibration structure 604 and on the support rollers 607 is in a stable and taut state, thereby preventing the printed packaging that has been corrected in the curling and overlapping problem from curling and overlapping again due to the action of the vibration structure 604.

[0039] The sliding sleeve 606 can slide up and down along the fixed rod 605, so that when the printed package presses against the support roller 607, the sliding sleeve 606 can be driven to move up and down to compress the spring 608 or make the spring 608 gradually extend in the direction of restoring its original length, so that the printed package is in a taut state and damage to the printed package is avoided.

[0040] The toggle structure 603 includes a rotating device 609 installed on a supporting top plate 623 and a rotating seat 610 rotatably connected to the supporting top plate 623, and the rotating seat 610 is connected to the rotating device 609, and two toggle plate groups are arranged on the peripheral side of the rotating seat 610, each toggle plate group includes a plurality of toggle plates 611 evenly arranged on the peripheral side of the rotating seat 610, and the two toggle plate groups are located on both sides of the rotating seat 610 that are perpendicular to the axis and bisect the cross-section of the rotating seat 610, and the two toggle plate groups are staggered.

[0041] The rotating device 609 drives the rotating base 610 to rotate, thereby driving the two toggle plate groups on the rotating base 610 to rotate simultaneously, and since the two toggle plate groups are staggered, when the toggle plate 611 in one of the toggle plate groups presses the vibration structure 604, the other toggle plate group will not resist the vibration structure 604, so that the two toggle plate groups toggle the vibration structure 604 in batches, and the two toggle plate groups cyclically press the vibration structure 604, so that the vibration structure 604 stably generates a vibration effect to be transmitted to the printed packaging, thereby eliminating the curling and overlapping at the edge of the printed packaging.

[0042] The vibration structure 604 includes a connecting frame 612 fixedly set on two groups of supporting side plates 601, and two opposite side walls in the connecting frame 612 are slidably connected with connecting plates 613. Each connecting plate 613 is rotatably connected with a plurality of pressure rollers 614 for rolling contact with the printed packaging, and the plurality of pressure rollers 614 on the two connecting plates 613 are staggered. The top of each connecting plate 613 is fixedly connected with a pressure plate 615 for abutting against the toggle plate 611 and a first elastic member 624 connected to the supporting side plate 601, and the first elastic member 624 is deformed in the vertical direction.

[0043] The two toggle plate groups respectively press the two pressure plates 615. When the toggle plate 611 in one of the toggle plate groups presses the pressure plate 615, the other toggle plate group does not contact the corresponding pressure plate 615, so that the pressure plate 615 under the pressure drives the connecting plate 613 to slide downward along the connecting frame 612, and stretches the first elastic member 624 to elastically deform. The multiple pressure rollers 614 on the connecting plate 613 move downward synchronously with the connecting plate 613, so that the printed package bends downward. When the toggle plate 611 in one of the toggle plate groups passes the pressure plate 615, the corresponding The connecting plate 613 is reset under the elastic force of the first elastic member 624, and the other toggle plate group presses the other pressing plate 615 to drive the multiple pressing rollers 614 on the other connecting plate 613 to descend, so that the multiple pressing rollers 614 on the two connecting plates 613 press the printed package alternately. The printed package vibrates in the process of being alternately pressed by the multiple pressing rollers 614 on the two connecting plates 613, so that the curling overlap at the edge of the printed package is restored during the vibration, thereby avoiding the impact on the quality of inkjet printing and die-cutting due to the curling overlap at the edge of the printed package.

[0044] Furthermore, the plurality of pressing rollers 614 on the two connecting plates 613 are arranged alternately, so that when the printed package is pressed by the pressing rollers 614 , the force distribution is relatively uniform, thereby avoiding damage to the printed package.

[0045] The pressure plate 615 includes a transverse plate 616 and a longitudinal plate 617 , wherein the transverse plate 616 is connected to the top of the connecting plate 613 , the longitudinal plate 617 is perpendicular to the transverse plate 616 , and the length direction of the longitudinal plate 617 is perpendicular to the axis of the pressure roller 614 .

[0046] The longitudinal plate 617 is connected by the transverse plate 616, and the longitudinal plate 617 is perpendicular to the pressure roller 614, so that the length of the longitudinal plate 617 on the rotation path of the pressure plate 615 is longer, which makes it easier for the pressure plate 615 to abut against the longitudinal plate 617 and push the connecting plate 613 down, avoiding the pressure plate 615 from abutting against the edge of the pressure plate 615 when entering the pressure plate 615.

[0047] A vertical plate 618 and a horizontal plate 619 are provided on two opposite side walls in the connecting frame 612. The vertical plate 618 is rotatably connected to a rotating seat 620. A plurality of groups of bristles 621 are evenly arranged on the circumference of the rotating seat 620. A driving device is provided on the horizontal plate 619. The driving device is connected to a transmission device connected to the rotating seat 620. The rotation center line of the rotating seat 620 is parallel to the horizontal plane and perpendicular to the axis of the pressure roller 614. An avoidance groove 622 is provided on the top of each connecting plate 613 for the vertical plate 618 and the horizontal plate 619 to pass through.

[0048] The driving device drives the rotating seat 620 to rotate through the transmission device, so that the multiple groups of bristles 621 on the multiple groups of rotating seats 620 rotate, so as to assist in brushing the curled and overlapping parts at the edge of the printed package toward the outside of the printed package, thereby assisting in smoothing the edge of the printed package and improving the correction effect of the curled and overlapping parts at the edge of the printed package.

[0049] In this embodiment, the bristles 621 are similar to a brush, with a large number of soft bristles on a mounting base.

[0050] The avoidance groove 622 is used to prevent the vertical plate 618 and the horizontal plate 619 from interfering with the movement of the connecting plate 613 .

[0051] The vertical plate 618 and the horizontal plate 619 form an inverted L-shaped plate body, which is used to install the rotating seat 620 and the driving device respectively to avoid occupying the space between the two pressing rollers 614.

[0052] The driving device and the transmission device are both existing technologies. For example, the driving device can be a motor, and the transmission device can be a gear set, etc.

[0053] Furthermore, a rotating seat 620 and bristles 621 may be provided at the bottom of the connecting frame 612 to assist in leveling the bottom surface of the printed package, thereby further improving the correction and leveling effect of the curled and overlapped portions at the edge of the printed package.

[0054] The elastic tensioning mechanism 7 includes a plurality of mounting frames 701 arranged on the bracket 1, each mounting frame 701 is provided with two second elastic members 702 capable of elastic deformation in the vertical direction, each second elastic member 702 is provided with a mounting block 703 slidably connected to the side wall of the mounting frame 701, and the two mounting blocks 703 on the same mounting frame 701 are rotatably connected to a tensioning roller 704, and the center line of the plurality of tensioning rollers 704 is wavy.

[0055] The plurality of mounting frames 701 are respectively mounted with the plurality of mounting blocks 703 through the second elastic member 702 , so as to mount the plurality of tensioning rollers 704 to abut against the printed package, so that the printed package is tensioned by the elastic force of the second elastic member 702 .

[0056] The center line connecting the multiple tensioning rollers 704 is wavy, that is, the heights of the multiple tensioning rollers 704 are different, and the heights of two tensioning rollers 704 separated by a tensioning roller 704 are the same, so that the printed package passes through multiple tensioning rollers 704, thereby improving the stability of the printed package during transportation.

[0057] In this embodiment, the first elastic member 624 and the second elastic member 702 are both existing technologies, and can be cylindrical springs or cylindrical springs arranged in a cylindrical tube, and a cylinder is sleeved in the cylindrical tube to resist the cylindrical spring. Either technical solution is available and can be selected according to actual needs.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
