Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing conveying, in particular to a paper conveying mechanism for die cutting and gold stamping. BACKGROUND

[0002] In the printing and packaging industry, die cutting and gold stamping is a key process to give products a beautiful appearance and unique texture, and is widely used in high-end gift packaging, delicate labels and artistic printed matter fields. As a core component of the die cutting and gold stamping equipment, the stability and precision of the paper conveying mechanism directly determine the quality and production efficiency of the product.

[0003] In recent years, with the enthusiasm of the consumer market for personalized and large-scale packaging, the use frequency of large-size paper in die cutting and gold stamping operations has increased significantly. However, the traditional paper conveying mechanism has obvious shortcomings when dealing with large paper. The conventional suction cup design is adapted to standard size paper. When facing large paper, the suction cup cannot completely cover the surface of the paper, resulting in insufficient suction area and difficulty in uniformly dispersing suction force. During the conveying process, the paper is prone to uneven force, leading to shaking, skewing or even falling off. This not only affects the precision of die cutting and gold stamping, but also may cause equipment failure and increase downtime maintenance time.

[0004] In addition, large paper has large mass and strong inertia, and requires more suction force to overcome gravity and friction during conveying. However, the suction force of the existing paper conveying mechanism is difficult to effectively improve, and cannot provide stable grabbing and conveying power for large paper, resulting in low conveying efficiency and inability to meet the needs of large-scale production. Therefore, it is of great practical significance to develop a paper conveying suction cup that can enhance the suction area and suction force of large paper, to break through the bottleneck of the current die cutting and gold stamping process and improve industrial competitiveness.

[0005] Chinese patent (publication number CN102774670B) discloses a paper conveying mechanism, which includes a paper box for storing multiple layers of paper and giving the multiple layers of paper a certain inclination angle to facilitate paper delivery; a paper separating mechanism connected to the paper box and delivering the paper in the paper box one by one; and a paper picking mechanism located in front of the paper box and picking away the delivered paper, which delivers the picked away paper to a paper conveying board. The paper box includes a paper feeding table where multiple layers of paper are placed; left and right paper alignment boards, front and rear paper blocking boards installed on the support and in contact with the four end surfaces of the paper feeding table, respectively, for positioning the multiple layers of paper on the paper feeding table, and the height of the rear paper pushing board is higher than that of the front paper blocking board; and a paper pushing device connected to the rear paper pushing board, which inclines the rear paper pushing board to push the multiple layers of paper on the paper feeding table out of position. The paper conveying mechanism of the invention is simple in structure, convenient to manufacture and process, and low in cost, and can realize continuous automatic paper feeding.

[0006] According to the above scheme, when the paper is conveyed, only the friction between the paper is reduced during conveying, and different sizes of paper cannot be adsorbed and conveyed, which has limitations. In order to solve the problem that different sizes of paper cannot be adsorbed and conveyed, we provide a die cutting and stamping paper conveying mechanism. SUMMARY

The outer wall of the slide bar 4 and the inner wall of the sliding opening are both smeared with lubricating oil.

The lubricating oil can also reduce the friction between the sliding opening and the slide bar 4, thereby prolonging the service life of the sliding opening and the slide bar 4. The left end of the mounting and matching plate 1 is fixedly installed with two second servo motors 2, and the two second servo motors 2 are symmetrically distributed in front and back at the left end of the mounting and matching plate 1. The right end of the mounting and matching plate 1 is rotatably connected with four belt pulleys 3 through a rotating shaft. A matching belt 5 is tightly sleeved between every two belt pulleys 3 parallel to the same horizontal plane. The output end of each second servo motor 2 is fixedly connected with the corresponding belt pulley 3, and the outer wall of each matching belt 5 is fixedly connected with the corresponding first moving block 7. Please refer to Figure 2 ;

[0042] The first moving block 7 is slidably connected with a moving pipe 6 away from one end of the mounting matching plate 1, the first moving block 7 is fixedly connected with an electric cylinder 8 inside, and the output end of the electric cylinder 8 is fixedly connected with the upper end of the moving pipe 6, the bottom of the moving pipe 6 is fixedly connected with an adjusting mechanism 101, and the bottom of the moving pipe 6 is also fixedly connected with an adsorption mechanism 201 capable of adsorbing paper, the adjusting mechanism 101 can adjust the adsorption mechanism 201, and different papers can be adsorbed, and the upper end of the moving pipe 6 is also fixedly connected with a suction force mechanism 301 capable of adjusting the suction force of the adsorption mechanism 201, when the paper to be conveyed is placed below the moving pipe 6 on the left side of the mounting matching plate 1, the electric cylinder 8 inside the first moving block 7 drives the moving pipe 6 to move downward at this time, the moving pipe 6 drives the adsorption mechanism 201 to adsorb the paper and moves the paper, when the adsorption mechanism 201 releases the paper, the moving pipe 6 is reset, and when the released paper is printed, another moving pipe 6 moves above the paper, and the suction force mechanism 301 at the bottom adsorbs and conveys the paper, and the two moving pipes 6 move reciprocatingly.

[0043] Embodiment two: please refer to Figures 4-6 As shown, the adjusting mechanism 101 comprises a first matching cylinder 12, the first matching cylinder 12 is slidably connected with a first piston 11 having a reset function inside, the first piston 11 and the inner wall of the first matching cylinder 12 are fixedly connected through a first spring 13, the first spring 13 can drive the first piston 11 to reset quickly, the bottom of the moving pipe 6 is also fixedly connected with a first servo motor 15, the first servo motor 15 has the function of limiting the output shaft after stopping, the first servo motor 15 is located on the right side of the first matching cylinder 12, the output end of the first servo motor 15 is fixedly connected with a recovery wheel 16, the outer wall of the recovery wheel 16 is wound with a first connecting rope 14, the free end of the first connecting rope 14 is fixedly connected with the first piston 11, the first spring 13 is sleeved on the outer wall of the first connecting rope 14, and the outer wall of the first connecting rope 14 is also slidably connected in the first matching cylinder 12, the bottom of the moving pipe 6 is also fixedly connected with two second matching cylinders 19, and the two second matching cylinders 19 are distributed in a left-right symmetrical manner at the bottom of the moving pipe 6;

[0044] The second matching cylinder 19 is filled with hydraulic oil, and the first matching cylinder 12 is in fixed communication with all the second matching cylinders 19 through pipelines. Each second matching cylinder 19 is slidably connected with a second piston 20. When the first servo motor 15 drives the recovery wheel 16 to rotate, the recovery wheel 16 pulls the first connecting rope 14, which in turn pulls the first piston 11. Since the liquid is incompressible, the hydraulic oil enters 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 move in opposite directions. Due to the hydraulic effect, the two second pistons 20 move at the same speed.

[0045] As shown in Figure 2 、 Figures 5-9 The adsorption mechanism 201 includes two second moving blocks 21, each of which is fixedly connected with an adjacent second piston 20 through a connecting arm. The bottom of the second moving block 21 is fixedly connected with an adsorption barrel 18, which is in fixed communication with the moving pipe 6 through an extension pipe. The bottom of the adsorption barrel 18 is conical, and the bottom of the adsorption barrel 18 is fixedly connected with a circular plate 30. A plurality of adsorption openings 29 are formed in the outer wall of the circular plate 30, and a plurality of matching rings 25 are arranged above the circular plate 30. Each matching ring 25 is fixedly connected with two abutting blocks 26 at the upper end, which are distributed symmetrically left and right at the upper end of the matching ring 25. Each matching ring 25 is fixedly connected with a plurality of second springs 28 between the circular plate 30, which can drive the matching ring 25 to reset quickly. A plurality of matching rings 25 are nested with each other, and each matching ring 25 is fixedly connected with a plurality of closing columns 27 at the bottom, which are distributed circumferentially at the bottom of the matching ring 25. The outer wall of each closing column 27 is matched with the inner wall of the adsorption opening 29 directly below.

[0046] The second elastic telescopic arm 39 is fixedly connected with the second moving block 21 at the left end, and the output end of the second elastic telescopic arm 39 is fixedly connected with the innermost one of all the matching rings 25 through a second connecting rope 24. The second connecting rope 24 is slidably arranged in the second moving block 21. The bottom of the moving pipe 6 is further fixedly connected with two triangular plates 22, which are distributed symmetrically left and right at the bottom of the moving pipe 6. A weight-reducing opening is formed in each triangular plate 22. The end of the second elastic telescopic arm 39 close to the triangular plate 22 is rotatably connected with an abutting wheel 23 through a rotating shaft. The outer wall of the abutting wheel 23 abuts against the outer wall of the triangular plate 22, which can effectively reduce the friction between the abutting wheel 23 and the triangular plate 22.

[0047] As shown in Figure 5 、 Figures 10-11As shown, the suction mechanism 301 comprises two connecting telescopic arms 33, both of which are fixedly connected to the upper end of the moving pipe 6, and the end of each connecting telescopic arm 33 away from the moving pipe 6 is fixedly connected with the adjacent second moving block 21 through the cooperation arm 17. The upper end of the moving pipe 6 is fixedly connected with a plurality of air pipes 32, which are arrayed from left to right on the upper end of the moving pipe 6. Each air pipe 32 is slidably connected with a cooperation column 10 having a reset function inside, and the cooperation column 10 and the inner wall of the air pipe 32 are fixedly connected through a cooperation spring 40, which can drive the cooperation column 10 to reset quickly.

[0048] The first cooperation block 37 is fixedly connected with a plug 31, which is conical, and the bottom of the plug 31 is fixedly connected with a rubber sealing ring. When the bottom of the plug 31 abuts against the upper end of the air pipe 32, the rubber sealing ring can enhance the sealing between the plug 31 and the air pipe 32.

[0049] Please refer to Figure 2 、 Figures 11-13 As shown, the upper end of the moving pipe 6 is fixedly connected with a second cooperation block 38, and the bottom of the second cooperation block 38 is fixedly connected with the moving pipe 6 through a pipe. The upper side of the second cooperation block 38 is provided with a first cooperation block 37, and the first cooperation block 37 and the second cooperation block 38 are fixedly connected with a plurality of first elastic telescopic arms 34, which are circumferentially distributed between the first cooperation block 37 and the second cooperation block 38. The upper end of the first cooperation block 37 is fixedly connected with a connecting pipe 9, and the outer wall of the first cooperation block 37 is fixedly connected with an abutting arm 35. The upper end of the mounting cooperation plate 1 is fixedly connected with two abutting cooperation blocks 36. It is worth noting that the camber height of the connecting pipe 9 is higher than the height of all the abutting cooperation blocks 36, and the height of the abutting arm 35 on the right side of the upper end of the moving pipe 6 is higher than the height of the abutting cooperation block 36 on the upper end of the moving pipe 6. In this way, when the abutting arm 35 on the right side of the upper end of the moving pipe 6 moves towards the abutting cooperation block 36 on the left side of the upper end of the moving pipe 6, the abutting arm 35 will not abut against and block the abutting cooperation block 36 on the left side of the upper end of the moving pipe 6.

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

[0051] When the application is used, the neatly stacked paper is placed directly below the moving pipe 6 at the left end of the mounting fitting plate 1, all the connecting pipes 9 are connected to the suction port of the air pump, the connecting pipes 9 will suck the moving pipe 6 through the first fitting block 37 and the second fitting block 38, the moving pipe 6 will suck the suction barrel 18, and then the electric cylinder 8 at the left side of the mounting fitting plate 1 is started, which will drive the corresponding moving pipe 6 to move downward, the moving pipe 6 will drive all the bottom of the suction barrel 18 below to abut against the upper end of the paper, the suction barrel 18 will suck the outer wall of the paper through the suction port 29 at the bottom, and when the outer wall of the paper is in abutment with the suction port 29, the second servo motor 2 at the left end of the mounting fitting plate 1 is started, which will drive the corresponding belt pulley 3 to rotate, the belt pulley 3 will drive the cooperating belt 5 to transmit, the cooperating belt 5 will drive the corresponding moving pipe 6 to move, the moving pipe 6 will drive all the suction barrels 18 to move simultaneously, and the suction barrel 18 will drive the sucked paper to move, when the abutment fitting block 36 at the left side of the upper end of the mounting fitting plate 1 abuts against the abutment arm 35 being moved, the electric cylinder 8 will drive the first moving block 7 to move downward, the first moving block 7 will move the paper downward through the suction barrel 18, so that the paper is placed on the set position, and at this time the abutment arm 35 will move upward along the inclined wall at the upper end of the abutment fitting block 36, the abutment arm 35 will drive the first fitting block 37 to move upward, when the first fitting block 37 is separated from the abutment with the second fitting block 38, at this time there is no suction in the suction barrel 18, and the suction barrel 18 will release the suction of the paper, when the printing on the outer surface of the paper is completed, the second servo motor 2 at the right side of the mounting fitting plate 1 is started again, at this time the other moving pipe 6 will drive the suction barrel 18 to suck the paper, and according to the above working principle, the printed paper can be moved and placed;

[0052] After the paper is placed, the moving pipe 6 will move back, at this time the abutment arm 35 will be separated from the abutment with the outer wall of the corresponding abutment fitting block 36, and the second fitting block 38 and the first fitting block 37 will be reset in abutment under the action of the first elastic extension arm 34, so that the second paper suction and taking can be performed;

[0053] When it is necessary to adsorb paper of different widths, only the first servo motor 15 is started to drive the recovery wheel 16 to rotate, the recovery wheel 16 will pull the first connecting rope 14, the first connecting rope 14 will pull the first piston 11, because 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-locked, so that the first spring 13 will press 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, the two second moving blocks 21 will drive the second moving blocks 21 to move in opposite directions, the second moving blocks 21 will drive the corresponding adsorption barrels 18 to move, the adsorption barrels 18 can adsorb paper of different widths through the adsorption ports 29, and paper of different widths can be adsorbed by adjusting the distance between the two adsorption barrels 18;

[0054] In the process of moving of the two second moving blocks 21, the second moving blocks 21 will drive the second elastic telescopic arms 39 to move, the second elastic telescopic arms 39 will drive the abutting wheels 23 to abut and slide on the outer wall of the triangular plates 22, in the process of elongation of the second elastic telescopic arms 39, the second elastic telescopic arms 39 will pull the second connecting ropes 24, the second connecting ropes 24 will pull the innermost matching ring 25 of all the 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, the second elastic telescopic arms 39 will continue to pull the second connecting ropes 24, the innermost matching ring 25 will abut against the outer wall of the abutting block 26 on the upper end of the abutting matching ring 25, thereby driving the corresponding matching ring 25 to move upward, when the matching ring 25 moves upward, the closing column 27 will be separated from the abutment with the inner wall of the adsorption port 29, so that more adsorption ports 29 are released, so that the adsorption area of the paper can be increased, and the problem that the surface of the paper is wrinkled due to a small adsorption area can be effectively avoided or the paper can be prevented from falling off;

[0055] And in the process of moving of the second moving blocks 21, the second moving blocks 21 will also pull the connecting telescopic arms 33 through the matching arms 17, when the matching arms 17 move, the connecting telescopic arms 33 will abut against the upper end of the corresponding block 31, when the block 31 is abutted, the block 31 moves downward to block the upper end of the air pipe 32, so that when the closing column 27 in the plurality of adsorption ports 29 is separated from the abutment, more air pipes 32 are blocked, so that the suction force of the released adsorption ports 29 will not be decayed.

[0056] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
