Description

Technical Field

[0001] This utility model relates to the field of packaging and printing production technology, specifically to a flange-flipping device for packaging and printing production. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressing. Printing is the process of transferring approved printing plates onto a substrate using printing machinery and specialized inks.

[0003] A search revealed a flange-flipping device for packaging and printing production, application number CN202421033952.9, comprising an operating table with lifting legs installed at the bottom. A first drive motor is installed inside the operating table, and a first transmission rod is splinedly connected to the output end of the first drive motor. A first transmission shaft is fixedly installed at one end of the first transmission rod, and a conveyor belt meshes with the surface of the first transmission shaft. A second transmission shaft meshes with the inner wall of the conveyor belt. A second drive motor is fixedly installed on the outer wall of the operating table, and a second transmission rod is splinedly connected to the output end of the second drive motor.

[0004] In this design, a second drive motor rotates a second transmission rod and a bidirectional threaded rod, causing the motor housing to move along the bidirectional threaded rod to a suitable position. Then, a servo motor drives a third transmission rod and a flanging plate to complete the flanging operation of the packaging bag, thus realizing the flanging function in the printing production process. However, in this design, one end of the flanging plate is fixed to the motor output shaft, while the other end is suspended. Over long-term use, this can easily lead to stress concentration on the motor output shaft, causing it to break and resulting in equipment interruption, affecting production continuity. Therefore, this solution provides a flanging device for packaging printing production to address the aforementioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, a flange-flipping device for packaging printing production is provided. This technical solution solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flanging device for packaging printing production includes an operating table and a packaging printing machine fixedly installed on the operating table. A feeding belt is provided on the lower side of the packaging printing machine, and a first flanging assembly and a second flanging assembly are respectively provided on both sides of the upper end of the feeding belt.

Two sets of flanging plates are symmetrically fixedly installed on the rotating rod, and an adjusting component is fixedly connected to the outer end of the sliding frame one.

[0009] Preferably, a connecting frame is fixedly connected between the first sliding frame and the two side sliding frames.

[0010] Preferably, a follower block 1 and a follower block 2 are fixedly connected to the middle of the rotating rod in a flip-over configuration, and a limit block 1 and a limit block 2 for limiting the follower block 1 and the follower block 2 are fixedly connected to both sides of the sliding frame 1, and the limit block 2 is located on the upper side of the limit block 1.

[0012] Compared with the prior art, this utility model proposes a flange-flipping device for packaging printing production, which has the following beneficial effects: 1. In this utility model, the screw drive of the drive component enables the centering adjustment of the first and second flanging components, so that the first and second flanging components can be adapted to packaging bags of different widths after they work together, eliminating the need to frequently replace the flanging components due to changes in product specifications, thus reducing equipment replacement costs and downtime.

[0013] 2. In this utility model, the first and second flanging components are symmetrically arranged and can be driven synchronously by the drive component, which effectively ensures that the flanging of both sides of the packaging is carried out synchronously, avoiding single-sided flanging and thus avoiding deviation; at the same time, during the flanging process, the cooperation between follower block one, limit block one, follower block two and limit block two achieves precise control of the flanging angle, avoiding inconsistent flanging angles caused by cylinder stroke error, thereby ensuring the positioning accuracy of subsequent printing processes.

[0014] 3. In the flipping assembly of this utility model, the sliding frame one and the sliding frame two used to support the flipped plate are rigidly connected by a connecting frame, which effectively enhances the overall resistance to deformation.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1 As shown, a flanging device for packaging printing production includes an operating table 1 and a packaging printing machine 2 fixedly installed on the operating table 1. A feeding belt 3 is provided on the lower side of the packaging printing machine 2, and a first flanging component 5 and a second flanging component 6 are respectively provided on both sides of the upper end of the feeding belt 3. A driving component 4 is provided at the bottom of the operating table 1. Reference Figure 2 As shown, specifically in this embodiment, the drive assembly 4 includes a mounting bracket 401 and a motor 402 fixedly installed at the bottom of the operating table 1. A threaded screw 403 is rotatably installed on the inner side of the mounting bracket 401. The output shaft of the motor 402 is fixedly connected to the threaded screw 403. A movable seat 404 is threadedly connected to the threaded screw 403. Connecting rods 405 are fixedly connected to both ends of the movable seat 404. The connecting rods 405 on both sides are fixedly connected to the first flange assembly 5 and the second flange assembly 6, respectively.

[0019] Furthermore: When the drive assembly starts, the motor 402 drives the threaded screw 403 to rotate. During the rotation of the threaded screw 403, the moving seat 404 is stabilized on the threaded screw 403 by the limiting of the connecting rods 405 on both sides, and the first flanging assembly 5 and the second flanging assembly 6 move synchronously through the connecting rods 405 on both sides. During the movement, the first flanging assembly 5 and the second flanging assembly 6 transmit power through their internal structure to achieve the centering adjustment of the flanging plate 506, so that it can be adapted to packaging bags of different widths. This eliminates the need to frequently replace the flanging parts due to changes in product specifications, reducing equipment replacement costs and downtime.

[0020] Reference Figure 2 As shown, specifically in this embodiment, the first flange assembly 5 and the second flange assembly 6 have the same overall structure, and the first flange assembly 5 and the second flange assembly 6 are symmetrically arranged on the front and rear sides of the operating table 1.

[0021] Furthermore, the first flanging component 5 and the second flanging component 6 are symmetrically arranged and can be driven synchronously by the driving component 4, which effectively ensures that the flanging of both sides of the packaging is carried out synchronously, avoiding single-sided flanging and thus avoiding deviation.

[0022] Reference Figure 3 As shown, specifically in this embodiment, the first flanging assembly 5 includes a sliding frame 1 501 and a sliding frame 2 502 slidably connected to the side wall of the operating table 1. Two sets of sliding frames 2 502 are provided and symmetrically arranged on both sides of the sliding frame 1 501. Rotating seats 503 are fixedly connected to the inner ends of both the sliding frame 1 501 and the sliding frame 2 502. A rotating rod 504 is rotatably mounted between the rotating seats 503. A tilting cylinder 505 is fixedly mounted on the left side of the rotating rod 504 and is fixedly connected to the output shaft of the tilting cylinder 505. Two sets of flanging plates 506 are symmetrically fixedly mounted on the rotating rod 504. An adjusting component is fixedly connected to the outer end of the sliding frame 1 501. A connecting frame 507 is fixedly connected between the sliding frame 1 501 and the two sliding frames 2 502 on both sides.

[0023] Furthermore, in the first flanging assembly 5, the sliding frame 501 and the sliding frame 502 used to support the flanging plate 506 are rigidly connected by the connecting frame 507, which effectively enhances the component's resistance to deformation. At the same time, the rotating rod 504 used to fix and install the flanging plate 506 is supported by multiple sets of rotating seats 503, so that the overall force is evenly distributed and the force is effectively distributed to the sturdy frame. This can improve the service life and operational stability of the equipment and avoid the problem of motor output shaft breakage caused by uneven force due to one end of the fixed frame being suspended in the air.

[0024] Reference Figure 5 As shown, specifically in this embodiment, the middle part of the rotating rod 504 is fixedly connected to a follower block 1 508 and a follower block 2 5010 that are rotated 180 degrees. The two sides of the sliding frame 1 501 are respectively fixedly connected to a limiting block 1 509 and a limiting block 2 5011 for limiting the follower block 1 508 and the follower block 2 5010, and the limiting block 2 5011 is located on the upper side of the limiting block 1 509.

[0025] Furthermore: During the flanging process, when the rotating rod 504 rotates, the follower block 1 508 and follower block 2 5010 in its upper middle part rotate synchronously; when follower block 1 508 contacts limit block 1 509 or follower block 2 5010 contacts limit block 2 5011, the rotating rod 504 stops rotating. Through the fixed mechanical limit structure, the flipping angle of the rotating rod 504 is precisely limited, avoiding over- or under-flanging, ensuring that the flanging angle of all packaging bags is consistent, effectively improving the flanging accuracy, thereby ensuring the positioning accuracy of subsequent printing processes.

[0026] Reference Figure 4 As shown, specifically in this embodiment, the adjusting component includes an anti-detachment plate 5012 fixedly installed on the sliding frame 501. A drive rod 5013 is fixedly installed on the anti-detachment plate 5012. A drive block 5014 is slidably connected to the lower end of the drive rod 5013, and a slanted groove 5015 for cooperating with the drive rod 5013 is provided through the drive block 5014. Fixing plates 5016 fixedly installed on the operating table 1 are provided on both sides of the drive block 5014. Two sets of guide rods 5017 are fixedly connected between the fixing plates 5016. Both sets of guide rods 5017 are slidably connected to the drive block 5014. The lower end of the drive block 5014 is fixedly connected to the connecting rod 405.

[0027] Furthermore: When the movable seat 404 moves under the rotation of the threaded screw 403, it drives the drive block 5014 in the first flanging assembly 5 through the connecting rod 405, causing it to slide along the guide rod 5017 between the fixed plates 5016; at this time, the inclined groove 5015 on the drive block 5014, through the sliding cooperation with the drive rod 5013 on the sliding frame 501, transforms the horizontal movement of the drive block 5014 into the inclined surface thrust of the inclined groove 5015, which drives the sliding frame 501 to slide smoothly along the side wall of the operating table 1. This realizes the transformation of the first coarse adjustment of the drive assembly 4 into the second fine adjustment of the flanging assembly, and effectively eliminates displacement deviation through the transmission of the inclined groove 5015, ensuring that the flanging plate 506 is accurately aligned with the edge of the packaging bag.

[0028] The working principle of this utility model is as follows: When in use, the drive assembly 4 is started, and the screw 403 is driven to rotate by the motor 402. During the rotation of the screw 403, the moving seat 404 is moved stably on the screw 403 by the limiting of the connecting rods 405 on both sides, and the first flanging assembly 5 and the second flanging assembly 6 are moved synchronously by the connecting rods 405 on both sides. The first flange component 5 and the second flange component 6 have the same overall structure. Taking the first flange component 5 as an example: When the movable seat 404 moves under the rotation of the threaded screw 403, it drives the drive block 5014 in the first flanging assembly 5 through the connecting rod 405, causing it to slide along the guide rod 5017 between the fixed plates 5016. At this time, the inclined groove 5015 on the drive block 5014, through its sliding cooperation with the drive rod 5013 on the sliding frame 501, transforms the horizontal movement of the drive block 5014 into the inclined surface thrust of the inclined groove 5015, which drives the sliding frame 501 to slide smoothly along the side wall of the operating table 1, ensuring that the flanging plate 506 is accurately aligned with the edge of the packaging bag.

[0029] Subsequently, after the packaged workpiece is in place, the rotating rod 504 is controlled by the flipping cylinder 505 to drive the flanging plate 506 to rotate. During the flanging process, when the rotating rod 504 rotates, the follower block 1 508 and follower block 2 5010 in its upper middle part rotate synchronously. When follower block 1 508 contacts limit block 1 509 or follower block 2 5010 contacts limit block 2 5011, the rotating rod 504 stops rotating. The flipping angle of the rotating rod 504 is precisely limited by the fixed mechanical limiting structure. Meanwhile, the sliding frame 501 and the sliding frame 502 used to support the flange plate 506 are rigidly connected by the connecting frame 507, which effectively enhances the component's resistance to deformation. At the same time, the rotating rod 504 used to fix the flange plate 506 is supported by multiple sets of rotating seats 503, so the overall force is evenly distributed and the force is effectively distributed to the sturdy frame. This can improve the service life and operational stability of the equipment and avoid the problem of motor output shaft breakage caused by uneven force due to one end of the fixed frame being suspended.
