[0016] A method for using a packaging carton conveying device comprises the following steps:

[0017] S1. The packaging cartons are piled up in the input bin. The main input belt is installed in the input bin to uniformly transport the packaging cartons backward. The transmission motor drives the transmission shaft to drive multiple insertion belts on the surface to drive simultaneously, waiting for the intermittent conveying mechanism on the intermediate bin to output to the output bin in sequence, so that the packaging cartons are arranged in order and centered;

[0018] S2. The conveying motor drives the conveying shaft to rotate through the conveying belt to simultaneously drive the toggle blocks on both sides to rotate. The toggle blocks toggle the internal sliding column and the rotating column to move in the rectangular path groove, and are connected to the transport platform through the vertical fixed column inside the rotating column and the top connecting frame on the top, so that the transport platform moves along the rectangular direction. After the packaging carton is transferred to the insertion belt, it will be clamped by the clamping and pushing mechanism. At this time, the insertion platform on one side of the transport platform is lifted from the bottom through the gap of the insertion belt and shovels the packaging carton onto the surface of the transport platform;

[0019] S3. When the transport platform moves toward the output bin, the toggle lever is pulled to drive the two moving blocks on the top to move closer, and the self-balancing block is pushed inward by the centering spring. The rotating moving column on the self-balancing block can rotate, and the driven gear at the bottom is engaged with the transport platform on the transport platform to achieve rotation while moving, and drive the push ring on the top to rotate. After the push ring contacts the packaging carton, it will continue to move inward for a distance, and then maintain the current position. At this time, the moving blocks on both sides continue to move inward to compress the centering spring, and when the push ring rotates, it will push the packaging carton on the surface of the transport platform further backward, and the packaging carton will be clamped inward to the center position during the pushing process. The insertion platform inserts the gap of the insertion belt from the other side to the top of the belt and puts down the packaging carton;

[0020] S4. When the vertical fixed column moves laterally along the rectangular path, it will pull the horizontal movable column to make it move laterally, and pull the pushing column forward by connecting the column, move on the pushing path groove, and push and pull the external platform to control the movement of the clamping and pushing shell. At this time, the inclined surface on the active pawl contacts the transmission chain, and will be continuously pushed open into the pushing column and stretch the tension spring, which will not drive the transmission chain to rotate. When the transport platform returns, the clamping and pushing shell will first be loosened, and the pushing column will push the horizontal moving column and the active pawl to move backward on the transmission chain. At this time, the active pawl cannot be lifted up, which drives the transmission chain to rotate. The transmission chain engages with the chain gear to drive the crawler mounting shaft to rotate, so that the pushing crawler set on the surface of the crawler mounting shaft rotates, and the packaging carton is actively pushed out to make it close to the transport platform.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, by the cooperation of the insertion input mechanism and the intermittent conveying mechanism, due to the gaps formed between the insertion belts, they will not hinder the up and down movement of the transport platform when lifting and lowering. The coordinated action of the toggle block and the sliding column enables the transport platform to move in a rectangular path, so that the transport platform can intermittently transport the packaging cartons in front to the rear in sequence, so that the packaging cartons can be transported according to a predetermined rhythm and interval.

[0023] In the present invention, the centering and advancement of the packaging carton during transportation is achieved through the provision of a transport centering mechanism. This design enables the packaging carton to automatically correct its position during transportation, ensuring that the carton is centered on the transport platform, reducing collisions or damages caused by position offset. At the same time, the cooperation of the centering spring and the self-balancing block increases the clamping force, ensuring the stability of the carton during transportation, and improving the safety and reliability of transportation.

[0024] In the present invention, by setting up the clamping and pushing mechanism, the effect of clamping when the transport platform is far away and pushing the clamped carton when it is close is achieved, thereby preventing the carton from sliding or falling off during transportation, and improving the transportation efficiency and the positioning accuracy of the carton.

In this way, the angle between the two side toggle rods 43 will become smaller. The closer the arc moving block 45 is, the closer the two side moving blocks 451 on the top are. The two side moving blocks 451 are rotatably connected with the arc moving block 45, so it will not rotate itself. Since the transport platform 44 moves along the rectangular path,The distance from the middle warehouse 11 will also become larger, so the hinged movable block 411 is connected to the toggle rod 43 through a movable connecting disk 42, and the movable connecting rod 422 on the movable connecting disk 42 is inserted into the movable connecting groove 421 on the next movable connecting disk 42, and the movable connecting rod 422 can slide on the movable connecting groove 421 to drive the movable connecting disk 42 to move in the vertical direction, so that the movable connecting disks 42 can be raised by staggering each other, so that the toggle rod 43 is raised to adapt to the distance between the transport platform 44 and the middle warehouse 11. In the process of approaching each other, the movable blocks 451 on both sides will push the self-balancing block 46 inward through the centering spring 462, and the rotating movable column 47 on the self-balancing block 46 can rotate, and the driven gear 471 at the bottom is engaged with the fixed rack 4711 on the transport platform 44 to realize rotation while moving, and drive the top push ring 472 to rotate, and the push ring 472 is annular with A larger contact area is provided, and the friction force is increased through the contact pad 4721 on the surface. Since the self-balancing block 46 can slide on the outer mounting platform 452 through the centering limit column 461, after the push ring 472 contacts the packaging carton, the contact force is small due to the short forward distance, and it cannot resist the reaction force of the centering spring 462. In addition, the contact pad 4721 can be pressed down and deformed, and will continue to move inward for a distance until the reaction force of the centering spring 462 is offset, and then maintain the current position to prevent the carton from being damaged. At this time, the moving blocks 451 on both sides continue to move inward to compress the centering spring 462 and increase the clamping force. When the push ring 472 rotates, the packaging carton on the surface of the transport platform 44 will be further pushed backward. Since the push rings 472 on both sides are close at the same time, the packaging carton will be clamped inward to the center position during the pushing process, so as to achieve the effect of centering and pushing the packaging carton during transportation and during transportation.

[0048] There are two articulated movable blocks 411, and the two articulated movable blocks 411 are symmetrically distributed with the central axis of the articulated fixed seat 41 as the symmetry axis. The movable connecting groove 421 is slidably connected with the movable connecting rod 422. There are five movable connecting disks 42 on each side, and the five movable connecting disks 42 are connected through the movable connecting groove 421 and the movable connecting rod 422. The outermost movable connecting disk 42 on each side is fixedly connected to the toggle rod 43. The insertion platform 441 is slidably connected to the outer surface of the insertion belt 2311. The platform 441 is symmetrically and equidistantly distributed on both sides of the transport platform 44. Both ends of the arc-shaped moving block 45 are slidably connected to the toggle limit ring 431. The transport platform 44 is fixedly connected to the top connecting frame 341. The moving blocks 451 on both sides are slidably connected to the inner surface of the component sliding groove 442. The centering limit column 461 penetrates the outer mounting platform 452 and is slidably connected to its inner wall. The rotating moving column 47 penetrates the self-balancing block 46. The fixed rack 4711 is fixedly connected to the inner surface of the component sliding groove 442. The symmetrical hinged movable blocks 411 plays the role of moving the arc-shaped moving block 45 inwards to clamp the packaging carton on both sides at the same time. The movable connecting plate 42 can be staggered with the movable connecting rod 422 through the movable connecting groove 421 to lift it up. The height of the toggle rod 43 is raised by connecting it with the toggle rod 43 at the outermost side. The insertion platform 441 is inserted through the gap of the belt 2311, lifted from the bottom and shoveled to the surface of the transport platform 44, and the top of the belt 2311 is inserted from the other side to put down the packaging carton. The insertion platforms 441 on both sides adapt to the Insert the belt 2311, and the transport platform 44 follows the intermittent conveying mechanism 3 through the top connecting frame 341 to realize the movement of the rectangular path. The arc movement of the arc moving block 45 drives the moving blocks 451 on both sides to move linearly on the component sliding groove 442. The self-balancing block 46 is limited on the external mounting platform 452 by the centering limit column 461 and can move linearly. The rotating moving column 47 penetrates to the bottom of the self-balancing block 46 so that the mutual rotation between the bottom driven gear 471 and the fixed rack 4711 can be transmitted to the top push ring 472.

[0049] The clamping and pushing mechanism 5 includes a clamping and pushing shell 51, which is slidably connected to the inner surface of the input bin 1, and the outer surface of the clamping and pushing shell 51 is fixedly connected to an outer platform 52, and a pushing path groove 521 is provided on the outer surface of the outer platform 52, and a pushing column 53 is slidably connected to the inner surface of the pushing path groove 521, and a connecting column 531 is fixedly connected to the bottom surface of the pushing column 53, and a horizontal moving column 5311 is slidably connected to the inner surface of the pushing column 53, and a tension spring 532 is sleeved on the outer surface of the horizontal moving column 5311, and an active ratchet 533 is fixedly connected to one end of the horizontal moving column 5311, and the inner surface of the clamping and pushing shell 51 is rotatably connected to a track mounting shaft 54, and the outer surface of the track mounting shaft 54 ​​is fixedly connected to Chain gear 541, the outer surface of the chain gear 541 is meshed with a transmission chain 542, and the outer surface of the track mounting shaft 54 ​​is sleeved with a pushing track 55. Through the setting of the clamping and pushing mechanism 5, during use, when the transport platform 44 moves toward the output bin 12, the transverse active column 35 will be pulled to move in the same direction of the output bin 12. The transverse active column 35 pulls the pushing column 53 forward through the connecting column 531. The pushing column 53 is connected to the oblique pushing path groove 521 on the outer platform 52 and is at the rear in the initial state. When moving forward, the transverse active column 35 and the pushing column 53 will only move horizontally, and the distance between them and the input bin 1 remains unchanged. Then the pushing column 53 will push the outer platform 52 inward through the pushing path groove 521. When the clamping and pushing shell 51 is pushed, the clamping and pushing shell 51 is also pushed inward to clamp the packaging carton inserted on the belt 2311 so that it waits for the transportation platform 44 to return next time and then be transported. The horizontal moving column 5311 on the pushing column 53 can be linearly moved to adjust the distance from the transmission chain 542 on the crawler mounting shaft 54. The horizontal moving column 5311 has a pulling effect through the tension spring 532 so that even after the clamping and pushing shell 51 moves inward, it will still be tightly attached to the surface of the transmission chain 542. When the active ratchet 533 on the horizontal moving column 5311 is inserted into the transmission chain 542, if the transportation platform 44 moves forward at this time, it means that the pushing column 53 pulls the horizontal moving column 5311 and the active ratchet 533 forward on the transmission chain 542. At this time, the active ratchet 533 The inclined surface on the upper part contacts with the transmission chain 542, and will be continuously pushed open into the pushing column 53 and stretch the tension spring 532. The tension spring 532 will be continuously reset, so that the active pawl 533 will not drive the transmission chain 542 to rotate. When the transport platform 44 returns, the clamping and pushing shell 51 will first be loosened, and the pushing column 53 will push the horizontal moving column 5311 and the active pawl 533 to move backward on the transmission chain 542. At this time, the straight edge on the active pawl 533 contacts the transmission chain 542. The active pawl 533 cannot be pushed up, which drives the transmission chain 542 to rotate. The transmission chain 542 is meshed with the chain gear 541 to drive the crawler mounting shaft 54 ​​to rotate, so that the pushing crawler 55 set on the surface of the crawler mounting shaft 54 ​​rotates.Thus, the packaging carton inserted on the belt 2311 is clamped when the transport platform 44 is far away, and the packaging carton is actively pushed out to make it close to the transport platform 44 when the transport platform 44 is close.

[0050] The clamping and pushing shell 51 passes through the input bin 1, the number of the clamping and pushing shells 51 is two, and the two clamping and pushing shells 51 are symmetrically distributed with the central axis of the input bin 1 as the symmetry axis, the pushing column 53 passes through the outer platform 52 through the pushing path groove 521, the pushing column 53 is fixedly connected to the transverse movable column 35, the horizontal moving column 5311 passes through the pushing column 53, the two ends of the tension spring 532 are respectively fixedly connected to one end of the pushing column 53 and the horizontal moving column 5311, the number of the crawler mounting shaft 54 ​​on each clamping and pushing shell 51 is two, and The two crawler mounting columns are symmetrically distributed with the central axis of the clamping and pushing shell 51 as the symmetry axis. The active pawl 533 is slidably connected to the inner surface of the transmission chain 542. The symmetrical clamping and pushing shell 51 has a clamping and pushing effect on both sides of the packaging carton at the same time. The pushing column 53 moves on the pushing path groove 521, and the external platform 52 pushes and pulls to control the movement of the clamping and pushing shell 51. The horizontal moving column 5311 can move horizontally on the pushing column 53, but will be pulled by the tension spring 532, so that the active pawl 533 is always close to the transmission chain 542.

[0055] In this embodiment, Figure 6 , Figure 7 As shown, the transport platform 44 also moves in a rectangular path, and the transverse movable column 35 is restricted by the transverse support frame 351 to move only transversely. The transverse movable column 35 firstly restrains the vertical fixed column 34 to prevent it from tipping over, and when the vertical fixed column 34 moves transversely in the rectangular path, it pulls the transverse movable column 35 to make it move transversely.

[0056] In this embodiment, Figure 8 As shown, the hinged fixing seat 41 is fixed on the intermediate bin 11 and will not move with the transport platform 44;

[0057] In this embodiment, Fig. 9 As shown, the angle between the two side toggle rods 43 can be reduced, and the arc-shaped moving blocks 45 are closer, driving the two side moving blocks 451 on the top to be closer, and the movable connection plates 42 can be raised by staggering each other, so that the toggle rods 43 are raised to adapt to the distance between the transport platform 44 and the intermediate bin 11;

[0060] In this embodiment, Fig.12 As shown, since the self-balancing block 46 can slide on the outer mounting platform 452 through the centering limit column 461, after the push ring 472 contacts the packaging carton, it will continue to move inward for a distance and then maintain the current position to prevent the carton from being damaged;

[0061] In this embodiment, Fig.13 As shown, when the transport platform 44 moves toward the output bin 12, the transverse movable column 35 will be pulled to move forward in the direction of the output bin 12, and the transverse movable column 35 pulls the push column 53 forward by connecting the column 531;

[0062] In this embodiment, Fig.14 As shown, the horizontal moving column 5311 has a pulling effect through the tension spring 532 so that even after the clamping and pushing housing 51 moves inward, it will still be tightly attached to the surface of the transmission chain 542, and the active pawl 533 is inserted into the transmission chain 542.

[0063] A method for using a packaging carton conveying device comprises the following steps:

[0064] S1, the packaging cartons are piled up in the input bin 1, the main input belt 21 is installed in the input bin 1, and is used to uniformly transport the packaging cartons backward, the transmission motor 23 drives the transmission shaft 231 to drive multiple insertion belts 2311 on the surface to drive simultaneously, and wait for the intermittent conveying mechanism 3 on the intermediate bin 11 to sequentially output to the output bin 12, so that the packaging cartons are arranged in order and centered;

[0065] S2, the conveying motor 31 drives the conveying shaft 32 to rotate through the conveying belt 311 to simultaneously drive the toggle blocks 33 on both sides to rotate, and the toggle blocks 33 drive the internal sliding column 331 and the rotating column 332 to move in the rectangular path groove 111, and are connected to the transport platform 44 through the vertical fixed column 34 inside the rotating column 332 and the top connecting frame 341 on the top, so that the transport platform 44 moves along the rectangular direction. After the packaging carton is transferred to the insertion belt 2311, it will be clamped by the clamping and pushing mechanism 5. At this time, the insertion platform 441 on one side of the transport platform 44 is lifted from the bottom through the gap of the insertion belt 2311 and shovels the packaging carton onto the surface of the transport platform 44;

[0066] S3, when the transport platform 44 moves toward the output bin 12, the toggle lever 43 is pulled to drive the moving blocks 451 on both sides of the top to move closer, and the self-balancing block 46 is pushed inward by the centering spring 462. The rotating moving column 47 on the self-balancing block 46 can rotate, and the driven gear 471 at the bottom is engaged with the transport platform 44 on the transport platform 44 to realize rotation while moving, and drive the pushing ring 472 on the top to rotate. After the pushing ring 472 contacts the packaging carton, it will continue to move inward for a distance, and then maintain the current position. At this time, the moving blocks 451 on both sides continue to move inward to compress the centering spring 462, and when the pushing ring 472 rotates, it will push the packaging carton on the surface of the transport platform 44 further backward, and the packaging carton will be clamped inward to the center position during the pushing process. The insertion platform 441 inserts the gap of the belt 2311 from the other side and puts down the packaging carton on the top of the belt 2311;

[0067] S4, when the vertical fixed column 34 moves laterally along the rectangular path, it will pull the horizontal movable column 35 to make it move laterally, and pull the push column 53 forward through the connecting column 531, move on the push path groove 521, and push and pull the external platform 52 to control the movement of the clamp push shell 51. At this time, the inclined surface on the active pawl 533 contacts the transmission chain 542, and will be continuously pushed open into the push column 53 and stretch the tension spring 532, which will not drive the transmission chain 542 to rotate. When the transport platform 44 returns, the clamping and pushing shell 51 will first be loosened, and the pushing column 53 will push the horizontal moving column 5311 and the active pawl 533 to move backward on the transmission chain 542. At this time, the active pawl 533 cannot be lifted up, so it drives the transmission chain 542 to rotate. The transmission chain 542 engages with the chain gear 541 to drive the track mounting shaft 54 ​​to rotate, so that the pushing track 55 sleeved on the surface of the track mounting shaft 54 ​​rotates, and the packaging carton is actively pushed out to make it close to the transport platform 44.

A method for using a packaging carton conveying device, characterized in that: Using a packaging carton conveying device as described in any one of claims 1 to 9 comprises the following steps: S1, packaging cartons are piled up in the input bin (1), a main input belt (21) is installed in the input bin (1) to uniformly transport the packaging cartons backwards, a transmission motor (23) drives a transmission shaft (231) to drive multiple insertion belts (2311) on the surface to simultaneously transport, and wait for the intermittent conveying mechanism (3) on the intermediate bin (11) to sequentially transport to the output bin (12), so that the packaging cartons are arranged in order and centered; S2, the conveying motor (31) drives the conveying shaft (32) to rotate through the conveying belt (311) to simultaneously drive the toggle blocks (33) on both sides to rotate, and the toggle blocks (33) to toggle the internal sliding column (331) and the rotating column (332) to move in the rectangular path groove (111), and are connected to the transport platform (44) through the vertical fixed column (34) inside the rotating column (332) and the top connecting frame (341) at the top, so that the transport platform (44) moves along the rectangular direction, and after the packaging carton is transferred to the insertion belt (2311), it will be clamped by the clamping and pushing mechanism (5), and at this time, the insertion platform (441) on one side of the transport platform (44) is lifted from the bottom through the gap of the insertion belt (2311) and shovels the packaging carton onto the surface of the transport platform (44); S3, when the transport platform (44) moves toward the output bin (12), the toggle lever (43) is pulled to drive the two side moving blocks (451) on the top to move closer, and the self-balancing block (46) is pushed inward by the centering spring (462), and the rotating moving column (47) on the self-balancing block (46) can rotate, and the driven gear (471) at the bottom is engaged with the transport platform (44) on the transport platform (44) to realize rotation while moving, and drive the push ring (472) on the top to rotate, and the push ring (472) on the push ring (472) is rotated. 72) After contacting the packaging carton, it will continue to move inward for a distance, and then maintain the current position. At this time, the moving blocks (451) on both sides continue to move inward to compress the centering spring (462), and when the pushing ring (472) rotates, it will push the packaging carton on the surface of the transport platform (44) further backward. During the pushing process, the packaging carton is clamped inward to the center position, and the insertion platform (441) passes through the gap of the insertion belt (2311) and inserts the packaging carton from the top of the other side of the insertion belt (2311) to put down the packaging carton; S4, when the vertical fixed column (34) moves laterally along the rectangular path, it will pull the horizontal movable column (35) to make it move laterally, and pull the push column (53) forward through the connecting column (531), move on the push path groove (521), push and pull the external platform (52) to control the movement of the clamp push shell (51), and at this time, the inclined surface on the active ratchet (533) contacts the transmission chain (542), and will be continuously pushed open into the push column (53) and stretch the tension spring (532), and will not drive the transmission chain (542) to rotate. When the transport platform (44) returns, the clamping and pushing shell (51) will first be loosened, and the pushing column (53) will push the horizontal moving column (5311) and the active ratchet (533) to move backward on the transmission chain (542). At this time, the active ratchet (533) cannot be lifted up, so it drives the transmission chain (542) to rotate. The transmission chain (542) engages with the chain gear (541) to drive the track mounting shaft (54) to rotate, so that the pushing track (55) sleeved on the surface of the track mounting shaft (54) rotates, and the packaging carton is actively pushed out to make it close to the transport platform (44).
