Description

Technical Field

[0001] This utility model relates to the printing field, and in particular to a modular cardboard bonding and splicing device. Background Technology

[0002] In existing technologies, the forming and processing of cartons and boxes with large unfolded areas are all carried out using post-printing machinery such as automatic die-cutting machines that process single sheets of paper. Figure 1 As shown. In the paper feeding section of the automatic die-cutting equipment, cardboard is stacked and fed into the main die-cutting unit for forming. After waste removal and other processes, the die-cut finished products are collected and stacked on the receiving unit, as shown. Figure 1 As the demand for packaged goods increases and the unfolded area of ​​cartons continues to expand, the machinery used for die-cutting and forming cartons from single sheets of cardboard becomes very large, resulting in higher processing costs and more difficult machine operation. This is especially true when using cardboard of different materials glued together in the same carton or box; automatic die-cutting machines that process single sheets cannot complete the forming process. Utility Model Content

[0003] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] The technical problem to be solved by this utility model is to provide a modular cardboard bonding and splicing device that can bond and splice large-format or multi-material cardboard boxes / cartons without using ultra-large format equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides a modular cardboard bonding and splicing device, comprising:

[0006] Automatic paper feeder unit, used to stack and output die-cut cardboard sheets one by one;

[0007] Automatic positioning glue spraying and cardboard bonding unit, detachably connected to automatic paper feeding unit;

[0008] The suction belt is installed on each automatic positioning glue spraying and cardboard bonding unit and has vacuum suction holes;

[0009] Servo motor drive mechanism is used to drive the suction belt and each automatic paper feeding unit.

[0010] Alternatively, the modular cardboard bonding and splicing equipment can be further improved by connecting automatic paper feeding units to both sides of the automatic positioning glue spraying and cardboard bonding unit.

[0011] Alternatively, the modular cardboard bonding and splicing equipment may be further improved by having multiple automatically positioned glue spraying and cardboard bonding units connected in series along the conveying direction for completing the continuous splicing of more than two pieces of cardboard.

[0012] Optionally, further improvements to the modular cardboard bonding and splicing equipment, including the automatic positioning glue spraying and cardboard bonding unit, include:

[0013] The horizontal slide rail, the vertical slide rail, and the electronically controlled glue gun assembly driven by a servo motor enable the glue nozzle to move along the X, Y, or diagonal trajectory.

[0014] Alternatively, the modular cardboard bonding and splicing equipment may be further improved by providing longitudinal and / or transverse paper pressing rollers above the suction belt.

[0015] Optionally, the modular cardboard bonding and splicing equipment can be further improved by providing an automatic paper feeding unit with a paper feeding platform that can be raised and lowered and a buffer suction head. The position of the buffer suction head on the suction head support rod is adjustable.

[0016] Optionally, the modular cardboard bonding and splicing equipment can be further improved by installing a suction plate that can be started and stopped in sections below the suction belt.

[0017] Optionally, the modular cardboard bonding and splicing equipment can be further improved by providing an external conveyor belt at the end for automatically collecting the finished spliced ​​and bonded products.

[0018] Alternatively, the modular cardboard bonding and splicing equipment can be further improved, with all servo motors achieving synchronous movement between units via a synchronous belt drive mechanism.

[0019] The working process of this utility model can be divided into the following parts;

[0020] 1. Decompose: Break down the unfolded diagram of a large-format or multi-material cardboard box into several individual pieces of cardboard;

[0021] 2. Feeding: Each sheet of cardboard is stacked on the feeding table of the corresponding automatic paper feeding unit;

[0022] 3. Conveying: The servo motor drives the paper feeding unit to sequentially feed individual sheets of cardboard to the suction belt;

[0023] 4. Positioning: Vacuum suction holes ensure the cardboard does not slip on the conveyor belt;

[0024] 5. Glue spraying: The XY servo system precisely sprays glue onto the area of ​​the cardboard to be glued according to a preset trajectory;

[0025] 6. Joining: The next piece of cardboard is sent to the glued area and pressed together;

[0026] 7. Cascading, multiple units are connected in series to complete the continuous splicing of ≥4 pieces of cardboard;

[0027] 8. Press firmly, and use longitudinal and transverse rollers for secondary rolling to improve adhesion strength;

[0028] 9. Collection: The finished product is output via an external conveyor belt.

[0029] The working principle is explained below;

[0030] Paper feeding units I 50 and II 46 are connected to both sides of the first bonding and splicing unit 73, and paper feeding units I 50 and II 46 are also connected to both sides of the second bonding and splicing unit 74. The first bonding and splicing unit 73 and the second bonding and splicing unit 74 are mirror-connected via the positioning conveyor belt 25 of the first unit and the positioning conveyor belt 67 of the second unit, and are simultaneously driven by a servo motor III 60 and a transmission mechanism. According to the needs of unfolding carton and box forming, the decomposed and die-cut single sheets of cardboard, paper, or sheet materials of different materials are stacked on the paper feeding platforms 45 of the paper feeding units I 50 and II 46. According to the bonding sequence, the single pieces of cardboard stacked on the paper feeding table 45 of the paper feeding unit I 50 are first positioned and conveyed to the positioning conveyor belt 25 of the first bonding and splicing unit 72, and glue 72 is sprayed on the parts that need to be bonded. Then, the paper feeding unit II 46 positions and conveys the single pieces of cardboard on the paper feeding table 45 to the position of bonding and splicing with the single pieces of cardboard on the conveyor belt 25, and bonds them with the single pieces of cardboard.

[0031] Servo motor III60 drives positioning conveyor belts 25 and 67 to position and transport the glued individual pieces of cardboard to the second bonding and splicing unit 74. Paper feeder unit I50 and paper feeder unit II 46 of the second bonding and splicing unit 74 sequentially transport the individual pieces of cardboard to the splicing and bonding positions already sprayed with glue 72, bonding them together. As servo motor III60 drives positioning conveyor belts 25 and 67 synchronously, the finished cartons and boxes 78, after splicing and bonding, are transported to the external conveyor belt 77 for collection.

[0032] This utility model can achieve at least the following technical effects;

[0033] 1. This utility model changes the large-format one-time die-cutting to multi-piece small-specification die-cutting + splicing, avoiding the use of ultra-large-format die-cutting machines and reducing equipment costs.

[0034] 2. The double / multi-sided paper feeding unit of this utility model can feed paperboards of different materials separately, solving the problem that different materials cannot be processed on the same machine.

[0035] 3. This utility model adopts vacuum adsorption + servo synchronous drive to ensure that the splicing error is ≤±0.5mm, thus guaranteeing the splicing accuracy.

[0036] 4. This utility model adopts multiple units in parallel and continuous conveying, with a cycle time comparable to that of traditional large-format die-cutting machines, which can improve production efficiency.

[0037] 5. This utility model achieves unattended operation throughout the entire process of automatic paper feeding, glue spraying, pressing, and collection, which can reduce labor intensity. Attached Figure Description

On the inner side of the drive side and the operating side wall panel of the paper feeder unit II 46, a driven synchronous pulley long support shaft seat 51 and a driven synchronous pulley short support shaft seat 55 are also fixedly installed, respectively. A driven synchronous pulley II 42 is installed on the driven synchronous pulley long support shaft seat 51.

Synchronous belt I4 is supported on driving synchronous pulley I6, driven synchronous pulley I3, and driven synchronous pulley II42; synchronous belt II44 is supported on driving synchronous pulley II41, driven synchronous pulley III43, and driven synchronous pulley IV8.

[0051] On the inner sides of the drive-side and operating-side wall panels 24 of the first bonding and splicing unit 72, and paper feeding units I 50 and II 46, slide rail support plates 23 are horizontally fixed. The length of the slide rail support plate 23 extends from paper feeding unit I 50 to paper feeding unit II 46. On the upper surface of the slide rail support plate 23 on the drive-side and operating-side, a longitudinal slide rail 20 is fixedly installed longitudinally. The length of the longitudinal slide rail 20 is approximately equal to the length of the slide rail support plate 23. On the longitudinal slide rail 20 on the drive-side and operating-side, near the side of paper feeding unit I 50, several slide blocks I19 are installed, and sliding support plates I18 are fixedly connected to the upper surface of the slide blocks I19. On the longitudinal slide rail 20 on the drive-side and operating-side, near the side of paper feeding unit II 46, several slide blocks I19 are also installed, and sliding support plates II 40 are fixedly connected to the upper surface of the slide blocks I19. On one side of the paper feeder unit I50, the synchronous belts I4 on the drive side and the operating side are pressed against the sliding support plate I18 by the synchronous belt pressure plate I16, thus fixing the synchronous belts I4 and the sliding support plate I18 together. On the other side of the paper feeder unit II 46, the synchronous belts II 44 on the drive side and the operating side are pressed against the sliding support plate II 40 by the synchronous belt pressure plate I16, thus fixing the synchronous belts II 44 and the sliding support plate II 40 together. When the servo motor I7 fixedly installed on the paper feeder unit I50 drives the drive shaft 54 ​​of the active synchronous belt pulley and the active synchronous belt pulley I6 to rotate, it can drive the synchronous belts I4 to rotate. And through the synchronous belts I4 on the drive side and the operating side, the sliding support plates I18 on both sides slide synchronously along the longitudinal slide rail 20. When the servo motor I 7, which is fixedly installed in the paper feeding unit II 46, drives the drive shaft 54 ​​and the drive pulley II 41 of the synchronous belt to rotate, it can drive the synchronous belt II 44 to rotate. And through the synchronous belt I 44 on the transmission side and the operation side, it drives the sliding support plates II 40 on both sides to slide synchronously along the longitudinal slide rail 20.

[0052] On one side of the upper surface of the sliding support plate I18 and sliding support plate II 40 on the drive side and operation side, respectively, a paper suction head lifting cylinder 17 is fixedly installed. A paper suction head lifting plate 12 is fixedly installed on the top plate 14 of the cylinder. On the lower surface of the paper suction head lifting plate 12, near the outer edge of the unit's axis of symmetry, a paper suction head lifting column 13 is vertically fixedly connected. Between the paper suction head lifting columns 13 on the drive side and operation side, a paper suction head lifting crossbar 15 is horizontally fixedly connected to the lower ends of the paper suction head lifting columns 13 on both sides. At the lower part of the paper suction head lifting crossbar 15, several paper suction head support rods 11 are fixedly connected along the X direction.

The position of the buffer paper suction heads 10 can be moved and adjusted in the long slots of the paper suction head support rods 11 as needed.

[0053] Between the sliding support plate I18 and sliding support plate II 40 on the transmission and operation sides, a transverse slide rail 39 is horizontally fixedly installed on the upper surface of each sliding support plate I18 and sliding support plate II 40. A slide block II 38 is installed on each transverse slide rail 39, and a small curved plate 32 is fixedly installed on the upper surface of each slide block II 38. A connecting block 29 is fixedly installed on each small curved plate 32, and an electrically controlled glue gun assembly 28 is fixedly installed on the connecting block 29. Glue pipe 30 supplies glue to the electrically controlled glue gun assembly 28, and glue gun control cable 31 controls the glue spraying time and amount. A longitudinal paper pressing roller 26 is also fixedly installed on the connecting block 29. A servo motor fixing plate 34 is fixedly installed on the upper surface of the sliding support plate I18 and sliding support plate II 40 near the transmission side wall panel 24. A servo motor II 37 is fixedly mounted on the servo motor mounting plate 34, and a drive synchronous pulley III 33 is fixedly mounted on the output shaft of the servo motor II 37. A synchronous pulley support seat 57 is fixedly mounted on the upper surface of the sliding support plate I 18 and the sliding support plate II 40 near the operating side wall plate 24, respectively. A support shaft 58 is fixedly mounted on the support seat 57, and a driven synchronous pulley V 59 is mounted on the support shaft 58. A synchronous belt III 36 is mounted on the drive synchronous pulley III 33 and the driven synchronous pulley V 59 on the paper feeder unit I 50 side and the paper feeder unit II 46 side, respectively. The synchronous belt III 36 passes close to the upper surface of the small curved plate 32 above it, and is pressed and fastened together by the synchronous belt pressure plate II 35. When the servo motor II 37 drives the active synchronous pulley III 33 to rotate, the synchronous belt III 36 can drive the small bending plate 32 and the electronically controlled glue gun assembly 28 mounted on the small bending plate 32 to move along the transverse slide rail 39 (along the Y direction).

[0054] At the junction of the first bonding and splicing unit 73 with paper feeding unit I 50 and paper feeding unit II 46, a first unit belt roller support wall plate 48 is symmetrically fixedly installed. Between the two first unit belt roller support wall plates 48, near the drive side, a driven belt roller I 22 is supported and mounted on a bearing seat fixed on the outer side of the wall plate 48. Between the two first unit belt roller support wall plates 48, near the operating side, a main drive belt roller 61 is supported and mounted on a bearing seat fixed on the inner side of the wall plate 48. At the shaft end near the paper feeding unit I 50, a drive synchronous pulley V 71 is fixedly installed, and the other end of the shaft of the main drive belt roller 61 is fixedly connected to the output shaft hole of servo motor III 60. Servo motor III 60 is fixedly mounted on servo motor support 62. Servo motor support 62 is fixedly mounted on the outer surface of the first unit belt roller support wall plate 48 near the paper feeding unit II 46. A drive synchronous pulley VI 63 is also fixedly installed on the main drive belt roller 61 between the outer side of the first unit belt roller support wall plate 48 and the servo motor III 60. A second unit belt roller support wall plate 65 is symmetrically fixedly installed at the junction of the second bonding and splicing unit 74 with the paper feeding unit I 50 and the paper feeding unit II 46. Between the two second unit belt roller support wall plates 65, near the drive side, a driven belt roller III 76 is supported and installed on a bearing seat fixed to the outer side of the wall plate. Between the two second unit belt roller support wall plates 65, near the operating side, a driven belt roller II 68 is supported and installed on a bearing seat fixed to the inner side of the wall plate 65. A driven synchronous pulley VI 69 is fixedly installed on the shaft end near the paper feeding unit I 50, and another driven synchronous pulley VI 69 is fixedly installed on the shaft end of the other end of the driven belt roller II 68. A synchronous belt IV 64 is installed on the driving synchronous pulley VI 63 and the driven synchronous pulley VI 69, and a synchronous belt V 70 is installed on the driving synchronous pulley V 71 and the driven synchronous pulley VI 69. A first unit positioning conveyor belt 25 is supported and installed on the main drive belt roller 61 and the driven belt roller I 22; a second unit positioning conveyor belt 67 is supported and installed on the driven belt roller II 68 and the driven belt roller III 76.

[0055] Several neatly arranged small holes are machined on the positioning conveyor belts 25 and 67. A suction disc 56 is fixedly installed below the positioning conveyor belts 25 and 67, and the suction disc 56 can control suction in different areas. Through the small holes, materials such as shaped cardboard conveyed to the positioning conveyor belts 25 and 67 can be adsorbed onto the positioning conveyor belts 25 and 67. When the servo motor III 60 drives the output shaft to rotate, the main drive belt roller 61, the active synchronous pulley VI 63, the driven synchronous pulley VI 69, the synchronous belt IV 64, the active synchronous pulley V 71, the driven synchronous pulley VI 69, and the synchronous belt V 70 drive the first unit positioning conveyor belt 25 and the second unit positioning conveyor belt 67 to move synchronously, positioning and conveying the glued cardboard from the first bonding and splicing unit 73 to the second bonding and splicing unit 74.

[0056] Based on the modular structural design, the second bonding and splicing unit 74 and the connected paper feeding unit I 50 and paper feeding unit II 46 have the same structure and working principle as the first bonding and splicing unit 73 and the connected paper feeding unit I 50 and paper feeding unit II 46.

[0057] When the above embodiments are in operation, according to the bonding process requirements (such as...) Figure 3(See the top view of the finished product 78 after splicing and bonding). Formed cardboard I is stacked on the paper feeding platform 45 of the paper feeding unit I 50 of the first bonding and splicing unit 73. The paper feeding platform drive motor 1 lifts the stacked formed cardboard I on the paper feeding platform 45 to a height close to the upper surface of the positioning conveyor belt 25. At this time, the servo motor I 7 drives the synchronous belt I 4 on the transmission side and the operation side to rotate, and the synchronous belt I 4 drives the sliding support plates I 18, which are symmetrically installed on the transmission side and the operation side, to slide synchronously along the longitudinal slide rail 20. A row of several buffer suction heads 10 are moved above the leading edge of the formed cardboard I by means of the suction head lifting cylinder 17 fixedly installed on the sliding support plates I 18 on both sides, the suction head lifting plate 12 installed on the cylinder top plate 14, and the suction head lifting column 13 and suction head lifting crossbar 15 installed on the suction head lifting plate 12. As the lifting cylinder 17 retracts along with the cylinder top plate 14, the lifting plate 12 moves downward, causing the buffer suction heads 10 to press against the leading edge of the formed cardboard I via the lifting crossbar 15. At this time, several buffer suction heads 10 near the leading edge suck in air, adsorbing the leading edge of the formed cardboard I onto the buffer suction heads 10. As the lifting cylinder 17 extends along with the cylinder top plate 14, the lifting plate 12 moves upward, causing the buffer suction heads 10 to lift the leading edge of the formed cardboard I via the lifting crossbar 15. Then, the servo motor 17 drives the synchronous belt 14 on both the transmission and operation sides to rotate. The sliding support plate 118 on both the transmission and operation sides drives the lifting crossbar 15 and the buffer suction heads 10 to position and transport the lifted formed cardboard I to a specific location on the positioning conveyor belt 25. At this time, the push rod of the suction head lifting cylinder 17 retracts along with the cylinder top plate 14, causing the suction head lifting plate 12 to move downwards. This moves the suction head lifting crossbar 15 and the buffer suction head 10 downwards together, placing the suction-held formed cardboard I onto the surface of the positioning conveyor belt 25. Simultaneously, the buffer suction head 10 stops suction, allowing the formed cardboard I to be adhered and fixed to the positioning conveyor belt 25. Afterwards, the push rod of the suction head lifting cylinder 17 extends, lifting the cylinder top plate 14 and the fixed suction head lifting crossbar 15 and buffer suction head 10.

[0058] After the buffer suction head 10 is lifted, servo motor I 7 drives the synchronous belt I 4 on the transmission side and the operation side to rotate, which in turn drives the symmetrically installed sliding support plate I 18, the transverse slide rail 39 fixedly installed on the sliding support plate I 18, and the servo motor II 37 fixedly installed on the servo motor fixing plate 34 to move along the longitudinal slide rail 20 (along the X direction). At the same time, as servo motor II 37 drives the active synchronous pulley III 33 to rotate, synchronous belt III 36 drives the small bending plate 32, the connecting block 29 installed on the small bending plate 32, and the electronically controlled glue spray gun assembly 28 on the connecting block 29 to move along the transverse slide rail 39 (along the Y direction). Therefore, under the joint drive of servo motor I 7 and servo motor II 37, the glue spray nozzle 27 can be moved to the starting point of the position on the formed cardboard I where glue needs to be sprayed.

[0059] After the nozzle 27 reaches the glue spraying start position, when servo motor II 37 moves and servo motor I 7 remains stationary, the electronically controlled glue spraying gun assembly 28 moves along the transverse slide rail 39 (along the Y direction) and sprays out a glue strip along the Y direction; when servo motor I 7 moves and servo motor II 37 remains stationary, the electronically controlled glue spraying gun assembly 28 moves along the longitudinal slide rail 20 (along the X direction) and sprays out a glue strip along the X direction, as shown below. Figure 3 (Top view) The formed cardboard I is shown. When servo motor I 7 and servo motor II 37 move simultaneously, an oblique adhesive strip can be sprayed. The glue gun control cable 31 controls the valve of the glue gun, determining the amount of glue sprayed. After the glue spraying is completed, the glue nozzle 27 of the paper feeder unit I 50 moves back to the origin O under the control of servo motor I 7 and servo motor II 37.

[0060] At this time, the paper feeding unit II 46 of the first bonding and splicing unit 73, as described above, driven by the servo motor I 7 of the paper feeding unit II 46, drives the symmetrically mounted sliding support plate I18 to move along the longitudinal slide rail 20 (along the X direction) via the synchronous belt II 44 on the transmission side and the operating side. This moves the suction head lifting crossbar 15 and a row of fixed buffer suction heads 10 to above the leading edge of the formed cardboard II stacked on the paper feeding table 45. Then, as mentioned before, the buffer suction heads 10 lift the leading edge of the formed cardboard II and, driven by the servo motor I 7, transport the leading edge of the formed cardboard II to above the Y-direction adhesive strip on the side of the formed cardboard I closest to the paper feeding unit II 46. The suction head lifting crossbar 15 moves downward under the drive of the lifting cylinder 17, pressing the leading edge of the formed cardboard II onto the adhesive strip via the buffer suction heads 10. Afterwards, the buffer suction head 10 stops sucking air, the suction head lifting crossbar 15 drives the fixed buffer suction head 10 to lift up, and returns to the initial position under the drive of the servo motor I 7.

[0061] After the formed paperboard I and the formed paperboard II are bonded together, the servo motor III 60 drives the main drive belt roller 61 and the driven belt roller II 68 to drive the first unit positioning conveyor belt 25 and the second unit positioning conveyor belt 67 to move synchronously, so as to transport the bonded formed paperboard I and the formed paperboard II to the second bonding and splicing unit 74.

[0062] Based on the modular structural design, repeating the aforementioned actions, the paper feeding unit II 46 of the second bonding and splicing unit 74 drives the synchronous belt II 44 on the transmission and operation sides via the servo motor I 7, causing the symmetrically installed sliding support plate I 18 to move along the longitudinal slide rail 20 (along the X direction). The paper suction head lifting crossbar 15 and the two rows of fixed buffer paper suction heads 10 are moved to the middle of the formed paperboard III stacked on the paper feeding table 45. The formed paperboard III stacked on the paper feeding table 45 is sucked up and lifted as a whole. The servo motor I 7 drives the synchronous belt II 44 to move, moving the side edge of the formed paperboard III above the adhesive strip sprayed along the X direction on the formed paperboard I, and pressing the side edge of the formed paperboard III onto the adhesive strip through the buffer paper suction heads 10. Subsequently, servo motors I 7 and II 37 on the paper feeding unit I 50 of the second bonding and splicing unit 74 move simultaneously along the X and Y directions, moving the connecting block 29 fixedly mounted on the small curved plate 32 and its connected longitudinal pressure roller 26 to the position facing the bonding of the forming paperboard III and the forming paperboard I. Servo motor II 37 stops, and servo motor I 7 moves, causing the longitudinal pressure roller 26 to move along the X direction and roll over the edge of the bonding of the forming paperboard III to improve the bonding force.

[0063] After the longitudinal pressing roller 26 completes rolling in the X direction, driven by the servo motor I 7 of the paper feeder unit I 50, the symmetrically mounted sliding support plate I 18 moves along the longitudinal slide rail 20 (in the X direction) via the synchronous belt I 4 on the transmission and operation sides. The suction head lifting crossbar 15 and a row of fixed buffer suction heads 10 are moved to above the leading edge of the formed paperboard IV stacked on the paper feeder plate 45. Then, as described above, the buffer suction heads 10 lift the leading edge of the formed paperboard IV and, driven by the servo motor I 7, transport the leading edge of the formed paperboard IV to above the Y-direction adhesive strip on the side of the formed paperboard I closest to the paper feeder unit I 50. The suction head lifting crossbar 15 moves downward under the drive of the lifting cylinder 17, pressing the leading edge of the formed paperboard IV onto the adhesive strip via the buffer suction heads 10. Afterwards, the buffer suction head 10 stops sucking air, the suction head lifting crossbar 15 drives the fixed buffer suction head 10 to lift up, and returns to the initial position under the drive of the servo motor I 7.

[0064] Several transverse paper-pressing rollers 75 are installed along the lower edge of the wall panel 24 on the drive side and the operating side. These rollers 75 can move parallel to the lower edge of the wall panel 24, aligning with the Y-direction adhesive strip bonding position. After the formed cardboard I, II, III, and IV are bonded, the servo motor III 60 drives the main drive belt roller 61 and the driven belt roller II 68 to drive the first unit positioning conveyor belt 25 and the second unit positioning conveyor belt 67 to move synchronously. As the finished product 78 is conveyed to the outside of the second bonding and splicing unit 74, the transverse paper-pressing rollers 75 roll over the already bonded cardboard at the Y-direction adhesive strip bonding position, improving the bonding force. The finished product 78 is then collected on the external conveyor belt 77.
