Description

Technical Field

[0001] The invention relates to the technical field of printing and conveying, in particular to a die-cutting and hot stamping paper conveying mechanism. Background Art

[0002] In the printing and packaging industry, die-cutting and hot stamping are key processes that give products exquisite appearance and unique texture. They are widely used in high-end gift packaging, exquisite labels, and art prints. The paper feeding mechanism is the core component of die-cutting and hot stamping equipment. Its paper feeding stability and accuracy directly determine the product quality and production efficiency.

[0003] In recent years, as the consumer market is keen on personalized and large-scale packaging, the frequency of using large-size paper in die-cutting and hot stamping operations has increased significantly. However, the traditional paper feeding mechanism has obvious shortcomings when dealing with large paper. The conventional suction cup design is adapted to standard-sized paper. When facing large paper, the suction cup cannot completely cover the surface of the paper, resulting in insufficient adsorption area and difficulty in evenly dispersing the adsorption force. During the transportation process, the paper is prone to uneven local force, resulting in shaking, skewing or even falling off, which not only affects the accuracy of die-cutting and hot stamping, but also may cause equipment failure and increase downtime for maintenance;

[0004] In addition, large papers have large mass and strong inertia, and require greater adsorption force to overcome gravity and friction during transportation. However, the adsorption force of the suction cup of the existing paper feeding mechanism is difficult to effectively improve, and cannot provide stable grasping and conveying power for large papers, resulting in low conveying efficiency and unable to meet the needs of large-scale production. Therefore, the development of a paper feeding suction cup that can enhance the adsorption area and adsorption force of large papers is of great practical significance for breaking through the bottleneck of the current die-cutting and hot stamping process and enhancing the competitiveness of the industry.

[0005] Chinese patent (Announcement No. CN102774670B), the patent discloses a paper conveying mechanism, which includes: a paper box for storing multiple layers of paper and making the multiple layers of paper have a certain tilt angle to facilitate the delivery of the paper; a paper separation mechanism connected to the paper box and delivering the paper in the paper box one by one; a paper gripping mechanism located in front of the paper box and taking away the delivered paper, which transfers the taken paper to the paper feeder. Among them, the paper box includes: a paper feeder with multiple layers of paper placed; a left-aligned paperboard, a right-aligned paperboard, a front stopper paperboard and a rear pusher paperboard installed on a bracket and contacting the four end faces of the paper feeder respectively, used to position the multiple layers of paper on the paper feeder, and the height of the rear pusher paperboard is higher than that of the front stopper paperboard; a paper pushing device connected to the rear pusher paperboard, which makes the rear pusher paperboard tilted so as to push the multiple layers of paper on the paper feeder to be displaced. The paper conveying mechanism of the invention has a simple structure, is easy to manufacture and process, has a low cost, and can realize continuous automatic paper supply.

[0006] According to the above scheme, when the above scheme is used, when conveying paper, it only reduces the friction between the two when conveying the paper, and when in use, it is unable to absorb and convey papers of different sizes, which has limitations. In order to solve the problem of being unable to absorb and convey papers of different sizes, we propose a die-cutting and hot stamping paper feeding mechanism. Summary of the invention

[0022] 1. When the present invention is used, the second moving block can drive the corresponding adsorption barrel to move flexibly. By adjusting the distance between the two adsorption barrels, the adsorption barrel can be adaptively adjusted according to the width of the paper. This design enables the adsorption port on the adsorption barrel to effectively adsorb papers of different widths, greatly improving the adaptability of the paper feeding mechanism to paper specifications. Whether it is narrow paper or large-format paper, it can be stably adsorbed, avoiding problems such as unstable adsorption and conveying deviation caused by differences in paper width, improving the stability of the production process and the processing accuracy of the product, effectively reducing the scrap rate, and enhancing the practicality of the equipment in diversified production demand scenarios;

[0023] 2.

The larger suction area can make the suction force more evenly distributed on the surface of the paper, effectively avoiding the occurrence of wrinkles due to uneven local force on the paper caused by the small suction area. At the same time, the larger suction area provides a stronger suction force, which greatly reduces the risk of paper falling off during transportation, ensures the stability of paper transportation, and improves product quality and production efficiency.

In this way, when the abutment arm 35 on the right side above the moving tube 6 moves toward the abutment block 36 on the left side of the upper end of the moving tube 6, the abutment arm 35 will not abut and block the abutment block 36 on the left side of the upper end of the moving tube 6.

[0050] The working principle of the present invention is:

[0051] When the present invention is used, the neatly stacked papers are placed just below the moving tube 6 located at the left end of the mounting and matching plate 1, and all the connecting tubes 9 are connected to the suction port of the vacuum pump. The connecting tube 9 will suck the moving tube 6 through the first matching block 37 and the second matching block 38, and the moving tube 6 will suck the adsorption barrel 18, and then the electric cylinder 8 located on the left side of the mounting and matching plate 1 will be started, and the electric cylinder 8 will drive the corresponding moving tube 6 to move downward, and the moving tube 6 will drive the bottom of all the adsorption barrels 18 below to abut against the upper end of the paper, and the adsorption barrel 18 will adsorb the outer wall of the paper through the adsorption port 29 at the bottom. When the outer wall of the paper is adsorbed and abutted against the adsorption port 29, the second servo motor 2 at the left end of the mounting and matching plate 1 will be started again, and the second servo motor 2 will drive the corresponding pulley 3 to rotate, and the pulley 3 will drive the matching belt 5 for transmission, and the matching belt 5 will drive the corresponding moving tube 6 to move, and the moving tube 6 will drive all the adsorption barrels 1 8 moves simultaneously, the adsorption barrel 18 will drive the adsorbed paper to move, when the abutting matching block 36 on the left side of the upper end of the installation matching plate 1 abuts against the moving abutting arm 35, the electric cylinder 8 will drive the first moving block 7 to move downward, and the first moving block 7 will move the paper downward through the adsorption barrel 18, so that the paper is placed in the set position, and at this time the abutting arm 35 will move upward along the inclined wall at the upper end of the abutting matching block 36, and the abutting arm 35 will drive the first matching block 37 to move upward, when the first matching block 37 is separated from the abutment with the second matching block 38, there is no suction inside the adsorption barrel 18 at this time, and the adsorption barrel 18 will release the adsorption of the paper, when the outer surface of the paper is printed, the second servo motor 2 on the right side of the installation matching plate 1 is started again, and at this time the other moving tube 6 will drive the adsorption barrel 18 to adsorb the paper, and then according to the above working principle, it can be known that the printed paper can be moved and placed;

[0052] After the paper is placed, the movable tube 6 will be reset, and the abutting arm 35 will be separated from the abutment with the outer wall of the corresponding abutting matching block 36, and the second matching block 38 and the first matching block 37 will be reset and abutted under the action of the first elastic telescopic arm 34, so that the second pair of paper can be sucked and taken;

[0053] When it is necessary to adsorb papers of different widths, it is only necessary to start the first servo motor 15 to drive the recovery wheel 16 to rotate, the recovery wheel 16 will pull the first connecting rope 14, and the first connecting rope 14 will pull the first piston 11. Since the liquid is incompressible, the hydraulic oil will enter all the second matching cylinders 19 through the first matching cylinder 12. At this time, the second pistons 20 in the two second matching cylinders 19 will move in opposite directions. When the first servo motor 15 stops rotating, the output end will be self-locking, so that the first spring 13 will squeeze the first piston 11, and the first connecting rope 14 will pull the first piston 11, so as to complete the limiting of the first piston 11, and the two second pistons 20 will drive the second moving blocks 21 to move in opposite directions, and the second moving blocks 21 will drive the corresponding adsorption barrels 18 to move, and the adsorption barrels 18 can adsorb papers of different widths through the adsorption port 29. By adjusting the distance between the two adsorption barrels 18, papers of different widths can be adsorbed;

[0054] When the two second moving blocks 21 move, the second moving blocks 21 will drive the second elastic telescopic arms 39 to move, and the second elastic telescopic arms 39 will drive the abutting wheels 23 to abut and slide against the outer wall of the triangular plate 22. When the second elastic telescopic arms 39 extend, the second connecting rope 24 will be pulled, and the second connecting rope 24 will pull the innermost matching ring 25 among all matching rings 25. When the two second moving blocks 21 continue to move in opposite directions, the second elastic telescopic arms 39 will continue to extend, and the second elastic telescopic arms 39 will continue to pull the second connecting rope 24. The innermost matching ring 25 will abut against the outer wall of the abutting block 26 at the upper end of the matching ring 25 abutting against it, and then drive the corresponding matching ring 25 to move upward. When the matching ring 25 moves upward, it will drive the closing column 27 to break away from the abutment with the inner wall of the suction port 29, so that more suction ports 29 are released, which can increase the suction area of ​​the paper. Since the suction area becomes larger, the problem of wrinkles on the surface of the paper due to the small suction area can be effectively avoided, or the paper can be prevented from falling off.

[0055] During the movement of the second movable block 21, the second movable block 21 will also pull the connecting telescopic arm 33 through the cooperating arm 17. When the cooperating arm 17 moves, it will also drive the connecting telescopic arm 33 to abut the upper end of the corresponding blocking block 31. When the blocking block 31 is abutted, the blocking block 31 moves downward to block the upper end of the ventilation pipe 32. In this way, when the closing column 27 inside the multiple suction ports 29 is out of contact, more ventilation pipes 32 are blocked, so that the suction force of the suction port 29 will not decline after being released.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
