Description

Technical Field

[0001] The invention relates to an automatic iron sheet pasting machine, belonging to the technical field of paper box processing. Background Art

[0002] With the rapid development of modern industry and the continuous improvement of people's living standards, people's demand for packaging boxes is constantly increasing. Packaging boxes are ubiquitous, and higher requirements are also placed on the convenience of product packaging boxes. A packaging box consists of a box body and a lid located above the box body. Usually, the lid of the packaging box needs to have a closing and locking function to prevent the lid from being accidentally opened.

[0003] To achieve the lid's closed locking function, a packaging box is designed in the prior art: two latches are installed on the inner side of the box body, and two iron plates are installed on the lid. When the lid is closed, the iron plates and the latches engage to lock the lid in place, preventing it from accidentally opening. In the prior art, the iron plates on the lid are typically attached manually. Workers apply glue to the iron plates and then attach them to the lid. Manually attaching the iron plates presents the following problems: 1. Low production efficiency, requiring a large amount of labor, occupying a large production area, and high labor costs. 2. Manual glue application can lead to uneven glue application, resulting in overflow and affecting the packaging's aesthetics, or insufficient glue, preventing the iron plates from adhering securely. 3. Because the iron plates need to engage with the latches, the precise placement of the iron plates is critical. Any deviation in the placement of the iron plates will prevent them from engaging with the latches on the box body. Manual attachment often results in scrap, waste of materials, and increased costs.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-13As shown, the automatic iron sheet pasting machine includes a frame 1, a turntable mechanism 6 mounted on the frame 1, a cardboard flipping and loading mechanism 2, a glue dispensing mechanism 3, an iron sheet pasting mechanism 4, a feeding mechanism 5, and an iron sheet pasting mechanism 7. The cardboard flipping and loading mechanism 2 is used to flip and load a cardboard 8 onto the turntable mechanism 6. In this embodiment, the cardboard 8 can be split into two box lids, connected by a dotted line in the middle to facilitate splitting. Two iron sheets 9 are required for each box lid, meaning there are four iron sheets on the cardboard 8. The iron sheet pasting mechanism 7 needs to position the four iron sheets 9. The turntable mechanism 6 rotates the cardboard 8 to face the glue dispensing mechanism 3. The glue dispensing mechanism 3 then applies glue to the cardboard 8. The turntable mechanism 6 then rotates the cardboard 8 to face the iron sheet pasting mechanism 4. The iron sheet pasting mechanism 4 removes the positioned iron sheet 9 from the iron sheet pasting mechanism 7 and places it onto the cardboard 8, ensuring full contact with the glue on the cardboard 8 and adhering to the cardboard 8. The blanking mechanism 5 blanks the cardboard 8 with the iron sheet 9 attached. This embodiment allows the iron sheet 9 to be attached to two lids simultaneously, which is more efficient. The iron sheet 9 is formed with a plurality of iron sheet holes 92. The end of the iron sheet 9 is bent downward to form iron sheet protrusions 91. The cardboard 8 has cardboard slots, and the iron sheet protrusions 91 are located in the cardboard slots, thereby positioning the iron sheet 9 for installation.

[0034] In the above technical solution: Figure 1 、 2 As shown in Figures 3 and 4, the cardboard turning and loading mechanism 2 includes a turning assembly 24, two loading side panels 21 mounted on the frame 1, a stacking side panel 23 mounted on the loading side panels 21, a discharge plate 22 mounted between the two loading side panels 21, and a pusher assembly 25 located at the bottom of the discharge plate 22. The discharge plate 22 is mounted at an angle between the two loading side panels 21. The stacking side panel 23 is located above and perpendicular to the discharge plate 22.

The piston rod of the flip cylinder 245 is extended and retracted, driving the flip moving plate 246 and the flip rack 247 to move, thereby driving the flip gear 243, the rotating shaft 241 and the flip push plate 242 to rotate.

[0038] In the above technical solution, a tilting guide rail 248 is mounted on the side of the loading side plate 21, and a tilting slider 249 is mounted on the tilting movable plate 246. The tilting slider 249 slides on the tilting guide rail 248 to guide the movement of the tilting movable plate 246. Two tilting movement limiting posts 2410 are also mounted on the side of the loading side plate 21 to limit the movement distance of the tilting movable plate 246.

[0039] In the above technical solution: Figure 1 、 5As shown in Figures 6 and 7, the turntable mechanism 6 includes a turntable motor 61 and a turntable divider 613. The turntable divider 613 is mounted on the frame 1 and connected to the turntable motor 61. A turntable base plate 62 is located on top of the turntable divider 613. The turntable motor 61 drives the turntable divider 613 to rotate the turntable base plate 62. During its rotation, the turntable base plate 62 passes through the cardboard flipping and loading mechanism 2, the glue dispensing mechanism 3, the iron sheet loading mechanism 7, the unloading mechanism 5, and the cardboard flipping and loading mechanism 2.

[0040] In the above technical solution, four sets of cardboard positioning blocks are provided on the turntable base plate 62, and the four sets of cardboard positioning blocks are arranged in pairs opposite to each other. The cardboard positioning blocks include a positioning movable block, a first positioning fixed block 63, two second positioning fixed blocks 619, and two positioning springs 64.

The two positioning springs 64 are arranged collinearly, and the two second positioning fixed blocks 619 are arranged collinearly and located opposite the positioning springs 64. A plurality of second spring adjustment holes 65 are formed on the turntable base plate 62. The positioning springs 64 are mounted on the turntable base plate 62 via spring mounting brackets 614. The positioning springs 64 are bent, and the ends of the positioning springs 64 are located within the second spring adjustment holes 65 and can move within the second spring adjustment holes 65.

[0041] In the above technical solution: Figure 5 、 6 As shown, the positioning movable block includes a rotating block 67, a movable spring piece 68, and a movable mounting block 66 mounted on the bottom of the turntable base plate 62. A mounting groove is formed on the movable mounting block 66, and a pin shaft 615 passes through the rotating block 67 and mounts the rotating block 67 in the mounting groove. The rotating block 67 can rotate around the pin shaft 615. The movable spring piece 68 is mounted on the top of the rotating block 67. A plurality of first spring piece adjustment holes 620 are formed on the turntable base plate 62.

The high contact surface 616 is located above the low contact surface 617. The fixed base 611 is installed between the unloading mechanism 5 and the cardboard turning and loading mechanism 2. As the turntable base 62 rotates and passes through the unloading mechanism 5 and the cardboard turning and loading mechanism 2, the rolling bearing 69 sequentially contacts the low contact surface 617, the inclined contact surface 618, and the high contact surface 616. The increase in the height of the rolling bearing 69 drives the rotating block 67 to rotate, causing the top of the movable spring 68 to move away from the first positioning fixed block 63.

A pasting slider 48 is mounted on the pasting transmission block 47. The pasting movement motor 41 drives the pasting slider 48 along the pasting transmission block 47. The transmission mechanism between the pasting movement motor 41, the pasting transmission block 47, and the pasting slider 48 is a synchronous gear drive. Two pasting transmission shafts are mounted within the pasting transmission block 47. The rotating shaft of the pasting movement motor 41 is connected to one of the pasting transmission shafts and the two pasting transmission shafts are arranged in the same direction. The two pasting transmission shafts are arranged in parallel. Both pasting transmission shafts are equipped with pasting synchronous gears, and a pasting belt is installed between the two pasting synchronous gears. The pasting slider 48 is connected to the pasting belt. When the pasting movement motor 41 starts running, it drives the pasting synchronous gears to rotate, which in turn drives the pasting slider 48 to move.

[0054] In the above technical solution, a pasting slider 48 is connected to two sides of a pasting side plate 49, and a pasting mounting plate 410 is installed between the two pasting side plates 49.

[0056] In the above technical solution: Figure 1 、 12As shown in Figures 1 and 13, the unloading mechanism 5 includes a unloading motor 53, an unloading plate 54, several unloading nozzles 55, and an unloading base 56 mounted on the frame 1. A unloading mounting block 57 is mounted on the top of the unloading base 56, and the unloading motor 53 is mounted on the unloading mounting block 57. The rotating shaft of the unloading motor 53 passes through the unloading mounting block 57 and is connected to a first unloading synchronous pulley 58. A second unloading synchronous pulley 59 is connected to the unloading plate 54, and an unloading belt 510 is sleeved between the first and second unloading synchronous pulleys 58, 59. Several unloading nozzles 55 are mounted on the bottom of the unloading plate 54. When the unloading motor 53 starts running, it drives the first and second unloading synchronous pulleys 58, 59 to rotate, and the unloading belt 510 starts to move, thereby driving the unloading plate 54 and the unloading nozzles 55 to rotate.

[0057] In the above technical solution: Figure 1 As shown, a blanking protection shell 520 is installed on the blanking mounting block 57. The first blanking synchronous wheel 58 and the second blanking synchronous wheel 59 are located in the blanking protection shell and are connected to the blanking protection shell 520. Figure 12 The blanking protective housing 520 is omitted. An adjustment roller 511, an adjustment connecting plate 512, and a mounting pin 513 are also provided within the blanking protective housing. The adjustment roller 511 and mounting pin 513 are hinged at both ends of the adjustment connecting plate 512, respectively. The mounting pin 513 is fixed to the inner wall of the blanking protective housing 520, allowing the adjustment connecting plate 512 and adjustment roller 511 to rotate relative to the mounting pin 513 and blanking protective housing, thereby adjusting the height of the adjustment roller 511. The adjustment roller 511 contacts the blanking belt 510 and is used to adjust the tension of the blanking belt 510.

[0058] In the above technical solution, the unloading mechanism 5 also includes a conveying motor 515, an unloading frame 51, and an unloading conveyor belt 52 located above the unloading frame 51. Two mounting side plates 514 are installed on the top of the unloading frame 51. Two unloading rotating shafts are installed between the two mounting side plates 514. The unloading conveyor belt 52 is sleeved on the two unloading rotating shafts. One end of the unloading rotating shaft passes through the mounting side plates 514 and is connected to a first conveying synchronous pulley 518. The conveying motor 515 is mounted on the unloading frame 51 via a motor mounting plate 516. The rotating shaft of the conveying motor 515 passes through the motor mounting plate 516 and is connected to a second conveying synchronous pulley 519. A conveying belt 517 is sleeved between the first and second conveying synchronous pulleys 518, 519. When the conveying motor 515 starts running, it drives the first and second conveying synchronous pulleys 518, 519 to rotate, thereby driving the two unloading rotating shafts to rotate, and the unloading conveyor belt 52 begins to move.

[0059] The working process of the present invention is as follows:

[0060] First, the cardboard sheets 8 are flipped and loaded. Several cardboard sheets 8 are stacked between the two stacking side plates 23. Before loading, the pusher block 253 is located at the end of the strip groove 221 away from the flip assembly 24. The piston rod of the flip cylinder 245 extends, driving the flip moving plate 246 and the flip rack 247 to move, thereby rotating the flip gear 243, the rotating shaft 241, and the flip push plate 242. The flip push plate 242 enters the strip groove 221, and the flip surface of the flip push plate 242 is coplanar with the upper surface of the unloading plate 22.

[0061] The cardboard 8 is pushed. The push cylinder 252 drives the push block 253 to move obliquely downward along the strip groove 221. The guide protrusion 2532 contacts the bottommost cardboard 8. Guided by the push ramp 2535, the cardboard 8 moves onto the guide protrusion 2532 and follows the tilt of the push ramp 2535. The end of the cardboard 8 away from the push block 253 tilts downward, allowing the cardboard 8 to pass through the gap between the bottom surface of the positioning bar 26 and the top surface of the discharge plate 22. The push protrusion 2531 drives the cardboard 8 obliquely downward. When the push connecting plate 251 contacts the push stop post 256, the push connecting plate 251 stops moving, and the pushing is complete. At this point, the cardboard 8 passes through the gap between the bottom surface of the positioning bar 26 and the discharge plate 22 and moves to contact the flip surface. The push stop block 244 stops the cardboard 8 in its position.

[0062] The pusher assembly 25 resets to prevent interference between the pusher assembly 25 and the cardboard 8 during the reversing process. The pusher cylinder 252 drives the pusher connecting plate 251 and the pusher block 253 to move diagonally upward and reset. During this reset, the pusher protrusion 2531 contacts the stacked cardboard 8. Guided by the reset bevel 2534, the pusher protrusion 2531 is forced downward by the stacked cardboard 8. This facilitates the reset of the pusher block 253 and prevents the pusher protrusion 2531 from being blocked by the stacked cardboard 8, which could affect the reset. When the pusher protrusion 2531 clears the stacked cardboard 8, it automatically pops out and resets. When the pusher connecting plate 251 contacts the pusher stop post 256, the pusher connecting plate 251 stops moving, completing the reset of the pusher assembly 25.

[0063] The turntable base 62 pauses, aligning one set of cardboard positioning blocks with the cardboard flipping and loading mechanism 2. The rolling bearing 69 now contacts the elevated contact surface 616. The piston rod of the flipping cylinder 245 shortens, moving the flipping movable plate 246 and the flipping rack 247. This in turn rotates the flipping gear 243, the rotating shaft 241, and the flipping push plate 242. The flipping push plate 242 rotates the cardboard 8 toward the turntable mechanism 6, placing it on the turntable base 62. During this rotation, the cardboard 8 is flipped, completing the loading process. The cardboard 8 is positioned within the cardboard positioning blocks, with its sides contacting the positioning springs 64 and the second positioning fixed block 619. The piston rod of the flipping cylinder 245 extends, rotating the flipping push plate 242 back to its original position. The cardboard flipping and loading mechanism 2 features a simple structure, eliminating the need for positioning sensors, reducing workstations, lowering costs, facilitating installation, and minimizing footprint.

[0064] Cardboard 8 is positioned. The turntable base 62 continues to rotate toward the dispensing mechanism 3. During the rotation, the rolling bearing 69 sequentially contacts the contact slope 618, the contact lower surface 617, and finally disengages from the contact block 612. The height of the rolling bearing 69 decreases, driving the rotating block 67 to rotate. The top of the movable spring 68 moves toward the first positioning and fixing block 63 until the movable spring 66 contacts the end face of the cardboard 8 and pushes the cardboard 8, so that the end face of the cardboard 8 contacts the first positioning and fixing block 63, completing the positioning of the cardboard 8. The cardboard positioning block eliminates the need for an electric cylinder drive during the positioning process of the cardboard 8, making cardboard positioning more convenient and quick. The cardboard positioning block occupies a small area, has a simple structure, is easy to install, and is low in cost. A positioning spring 64 and a second positioning and fixing block 619 are also provided to position the side of the cardboard 8, thereby completing the precise positioning of the cardboard 8.

[0065] Glue is applied to the cardboard 8. The turntable mechanism 6 drives the cardboard 8 to rotate to face the glue dispensing mechanism 3, and the glue dispensing moving motor 31 drives two sets of glue dispensing guns 36 to move horizontally. The glue dispensing guns 36 apply glue to the four positions of the cardboard 8 where the iron sheet 9 needs to be installed.

[0066] During the above process, the iron sheet 9 begins to be loaded. The cardboard 8 includes two box covers, each of which is equipped with two iron sheets 9. Therefore, each set of iron sheet positioning components 71 needs to position two iron sheets 9. Several iron sheets 9 are neatly stacked in the iron sheet stacking trough, and the iron sheet 9 at the bottom is in contact with the iron sheet guide block 713. Because of the presence of the iron sheet protrusion 91 at the bottom of the iron sheet 9, when the iron sheet 9 is stacked in the iron sheet stacking trough, the iron sheet protrusion 91 can only be located away from the loading direction of the iron sheet 9 and in contact with the bottom of the iron sheet stacking trough, thereby preventing the iron sheet 9 from getting stuck when loading. When it is necessary to move the iron sheet 9, the iron sheet positioning motor 711 starts running, driving the iron sheet push nozzle 719 to move. The iron sheet push nozzle 719 contacts the iron sheet at the bottom of the stacking and drives the iron sheet to move. When the iron sheet moves to contact the iron sheet moving limit block 7115, the iron sheet stops moving and is positioned in place. The push nozzle groove 7192 prevents the iron sheet push nozzle 719 and the iron sheet protrusion 91 from interfering with each other.

[0067] The iron sheet positioning motor 711 drives the iron sheet push nozzle 719 to reset. During the reset process, the iron sheet push nozzle 719 contacts the iron sheet 9 in the iron sheet stacking trough, and under the guidance of the push nozzle inclined surface 7191, the iron sheet push nozzle 719 is squeezed by the iron sheet 9 in the stacking state and begins to rotate. At this time, the push nozzle spring is compressed, and the push nozzle inclined surface 7191 is tilted horizontally and located below the iron sheet 9 in the iron sheet stacking trough, making the reset process of the iron sheet push nozzle 719 smoother and preventing the iron sheet push nozzle 719 from being blocked by the iron sheet 9 in the stacking state and affecting the reset. When the iron sheet push nozzle 719 is separated from the iron sheet 9 in the iron sheet stacking trough, the elastic force of the push nozzle spring is released, driving the iron sheet push nozzle 719 to reset to the initial state. The iron sheet positioning motor 711 drives the iron sheet pushing nozzle 719 to move again. The iron sheet pushing nozzle 719 contacts the iron sheet at the bottom of the pile and drives the iron sheet to move. The iron sheet positioning motor 711 is provided with a stroke for this movement. When the iron sheet positioning motor 711 stops running, the iron sheet is positioned in place.

[0068] The iron sheet picking assembly 72 picks up the two iron sheets that have been positioned on the iron sheet positioning assembly 71, and drives the iron sheets to move to the iron sheet transfer assembly 73. The picking motor 7217 drives the two picking mobile manipulators to move to the iron sheet positioning assembly 71, and the picking telescopic electric cylinder 724 drives the picking suction nozzle 727 to move down to pick up the two iron sheets 9 that have been positioned, and the picking telescopic electric cylinder 724 drives the picking suction nozzle 727 and the two iron sheets 9 to move up. The picking motor 7217 drives the picking mobile manipulator and the two iron sheets 9 to move to the iron sheet transfer assembly 73, and the picking mobile manipulator places the iron sheet 9 on the iron sheet placement slot 736 of the iron sheet transfer assembly 73. Since the subsequent iron sheet transfer assembly 73 will drive the iron sheet 9 to rotate, in order to make the position of the rotated iron sheet 9 and the cardboard 8 on the turntable mechanism 6 correspond, the picking mobile manipulator places the iron sheet 9 on the farther iron sheet placement slot 736.

[0069] The transfer motor 731 of the iron sheet transfer assembly 73 starts to run, driving the transfer base plate 733, the transfer pallet 734 and the iron sheet 9 to rotate, so that the transfer pallet 734 with the iron sheet 9 is rotated close to the turntable mechanism 6, and the transfer pallet 734 without the iron sheet 9 is located below the iron sheet picking assembly 72, waiting for the iron sheet 9 to be loaded.

[0070] The iron sheet pasting mechanism 4 moves the iron sheet 9 onto the cardboard 8 and pastes the iron sheet 9 onto the cardboard 8. The turntable mechanism 6 drives the cardboard 8 to rotate until it is facing the iron sheet transfer assembly 73. The pasting lifting electric cylinder 43 of the iron sheet pasting mechanism 4 drives the pasting lifting plate 45 and the positioning column 414 to move downward, and the positioning head 415 passes through the positioning hole 441. The pasting moving motor 41 drives the pasting lifting cylinder 42 to move above the transfer tray 734 where the iron sheet 9 is placed. The pasting lifting cylinder 42 drives the positioning column 414 and the pasting suction nozzle 46 to move downward. The end of the positioning head 415 is first inserted into the iron sheet hole 92 on the iron sheet 9 to position the iron sheet 9. The pasting suction nozzle 46 then sucks the iron sheet 9. The pasting moving motor 41 drives the sucked iron sheet 9 to move to the top of the cardboard 8 on the turntable mechanism 6. The pasting lifting cylinder 42 drives the iron sheet 9 to move downward. The iron sheet 9 contacts the glue on the cardboard 8 and is pasted on the cardboard 8. The electric cylinder 43 drives the lifting plate 45 and the positioning post 414 upward, disengaging the positioning head 415 from the iron sheet hole 92 and retracting it into the positioning hole 441. The adhesive nozzle 46 releases the iron sheet 9, and the pneumatic cylinder 42 drives the adhesive nozzle 46 upward. The iron sheet feeding mechanism 7 precisely positions the iron sheet 9, and the iron sheet pasting mechanism 4 ensures that the iron sheet 9 and the cardboard 8 are accurately and precisely positioned, significantly improving the product quality rate.

[0071] The unloading mechanism 5 unloads the cardboard 8 with the iron sheet 9 attached. The turntable mechanism 6 rotates the cardboard 8 with the iron sheet 9 attached until it faces the unloading conveyor belt 52. The unloading motor 53 rotates the unloading plate 54 and the unloading nozzle 55, causing the unloading nozzle 55 to pick up the cardboard 8 with the iron sheet 9 attached from the turntable mechanism 6. The unloading motor 53 then rotates the unloading nozzle 55 and the cardboard 8 with the iron sheet 9 attached, placing the cardboard 8 with the iron sheet 9 attached on the unloading conveyor belt 52. The conveyor motor 515 operates, driving the unloading conveyor belt 52 and the cardboard 8 with the iron sheet 9 attached to move the unloading conveyor belt 52.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should fall within the scope of protection of the present invention.
