Description

Technical Field

[0001] This invention relates to a cartoning machine, specifically a cartoning machine for pharmaceutical glass bottles. Background Technology

[0002] A pharmaceutical glass bottle cartoning machine is a device that packs small-capacity glass containers for injections, such as vials and ampoules, into cardboard boxes. Because some pharmaceutical glass bottles lack plastic bases, existing cartoning machines also incorporate a partition feeding device to prevent squeezing and collisions between the bottles. This device inserts a partition from top to bottom between two rows of vials, effectively isolating them. However, this top-to-bottom insertion method can easily interfere with vials whose cap diameter is equal to the bottle body diameter, leading to jamming and even bottle damage. Summary of the Invention

Detailed Implementation

[0016] like Figure 1 As shown, this pharmaceutical glass bottle cartoning machine includes a frame 1, a material grid conveying device 5, a carton grid conveying device 6, a partition feeding device 4, and an infeed pushing device 7. Pharmaceutical glass bottles are conveyed via the glass bottle feeding device 2, and then multiple sets of pharmaceutical glass bottles are simultaneously sucked onto the material grid conveying device 5 by the robotic arm 3. Figure 12 As shown, the material grid conveying device 5 includes a feeding grid belt for placing materials (the materials refer to pharmaceutical glass bottles X), and the pharmaceutical glass bottles are placed on the feeding grid belt and conveyed forward; as Figure 9 As shown, the partition feeding device 4 is used to place the partition between two rows of pharmaceutical glass bottles X, serving as a separator; while the carton grid conveyor 6 is located on one side of the material grid conveyor 5, and the carton grid conveyor 6 includes a feeding grid belt for placing carton H, on which the carton H is placed and conveyed forward; the box feeding pusher 7 includes a pushing mechanism, such as... Figure 10 As shown, the pushing mechanism includes a pushing rod 70 and a pushing power source 72 that drives the pushing rod 70 to move left and right; Figure 11 As shown, the pusher rod 70 can push the pharmaceutical glass bottle X into the cardboard box H, and finally the cardboard box H enters the box closing process to complete the boxing work (the box closing process is existing technology).

[0017] like Figure 2 As shown, this partition feeding device 4 includes a support 41 and a storage bin 42. The storage bin 42 is used to store a stack of partitions B. The bottom of the storage bin 42 has a support edge and a discharge port. The support edge is used to support the partitions B, and the bottom partition B can pass through the discharge port when it is sucked down.

[0018] In order to enable the partition B to be placed on its side, such as Figure 3 As shown, a partition bin 43 for accommodating a single partition is installed on the support 41 (the partition bin 43 keeps partition B upright and prevents partition B from tilting to the left or right). A partition unloading mechanism 44 for moving partitions from the material storage bin to the partition bin 43 is installed on the support 41. Figure 4 As shown, the partition feeding mechanism 44 includes a suction nozzle 440 for holding the partition; as Figure 2 As shown, a partition pushing mechanism 45 is installed on the bracket 41, such as... Figure 5 and Figure 7 As shown, the partition pushing mechanism 45 includes a pusher plate 450 and a pushing power source 451 that drives the pusher plate 450 to move back and forth, and the pusher plate 450 is located inside the partition compartment 43; Figure 8 As shown, the pusher plate 450 has a support part 4501 and a pusher part 4502. The support part 4501 extends in the front-back direction, and the pusher part 4502 is located above the rear side of the support part 4501 (the two form an L-shaped space). After the partition unloading mechanism 44 places the partition B into the partition bin 43, the partition B is placed on the support part 4501 of the pusher plate 450. When the pusher plate 450 moves forward, the pusher part 4502 of the pusher plate 450 can push the partition B forward.

[0019] Its working principle is as follows: The suction nozzle 440 of the partition feeding mechanism 44 moves a partition B from the material storage 42 to the partition bin 43. The partition bin 43 keeps the partition B upright on its side. Figure 7 As shown, at this time, partition B is located on the support part 4501 of pusher plate 450. Then, pusher power source 451 drives pusher plate 450 to move forward, and pusher part 4502 of pusher plate 450 pushes partition B forward, as shown. Figure 9 As shown, since there is a flared opening X1 (a naturally formed inlet between circles) between the sides of the two rows of vials X, the partition B can smoothly and steadily enter between the two rows of vials X, thus placing the partition B more stably.

[0020] The partition feeding mechanism 44 can adopt a feeding structure from the prior art, as long as it can suck the partition B out of the material magazine 42 and place it into the partition bin 43. A specific implementation of the partition feeding mechanism 44 is provided below.

[0021] like Figure 3 and Figure 4As shown, the partition unloading mechanism 44 includes a suction nozzle rod 441, a lifting seat 442, a rotating guide plate 445, and a lifting power source 449. A suction nozzle 440 is mounted on the suction nozzle rod 441 (the suction nozzle 440 is a vacuum suction nozzle capable of generating negative pressure). The suction nozzle rod 441 is rotatably mounted on the lifting seat 442. One end of the suction nozzle rod 441 is connected to a swing arm 443, and the other end of the swing arm 443 is connected to a guide member 444 (guide wheel or guide column). Figure 4 As shown, the rotating guide plate 445 is provided with a guide groove 446 extending vertically, and the guide member 444 is matched and disposed in the guide groove 446 of the rotating guide plate 445. The guide groove 446 has an upper guide section and a lower guide section that communicate with each other, and the upper guide section and the lower guide section are staggered left and right; the material storage 42 is located above the partition bin 43.

[0022] The working principle of this partition unloading mechanism 44 is as follows: The lifting power source 449 (linear module or other motor drive mechanism) drives the lifting seat 442 to move linearly upward. Since one end of the swing arm 443 is connected to the suction rod 441 and the other end is connected to the guide member 444, the guide member 444 can move within the guide groove 446 when the lifting seat 442 is raised and lowered. Since the upper guide section and the lower guide section of the guide groove 446 are staggered left and right, when the guide member 444 transitions from the lower guide section to the upper guide section, the swing arm 443 can move. The swing arm 443 can swing 90°, thus driving the suction rod 441 to rotate. When the lifting seat 442 reaches its highest position, the suction nozzle 440 faces upward, sucking up the partition B in the material storage 42. After the suction nozzle 440 sucks up the partition B, it drives the lifting seat 442 to move linearly downward. Based on the same principle, the swing arm 443 can drive the suction rod 441 to rotate. When the lifting seat 442 reaches its lowest position, the suction nozzle 440 faces to one side, allowing the partition B to enter the partition bin 43 (the feeding method of the partition B is as follows). Figure 8 (As shown). This partition feeding mechanism 44, through the cooperation of the guide groove 446 and the guide member 444, enables the suction nozzle 440 to rotate, which not only ensures stable operation and precise action, but also reduces manufacturing costs.

[0023] like Figure 7 As shown, the front end of the support part 4501 is pointed, and the length of the support part 4501 is greater than the length of the partition B (the front-to-back length of the partition B when it is standing on its side). When the partition B is placed on the support part 4501, the front end of the support part 4501 extends beyond the frontmost position of the partition B. When the pusher plate 450 moves forward to push the material, the front end of the support part 4501 can separate the left and right rows of vials X slightly, so that the partition B can enter between the left and right rows of vials X without obstruction, preventing the partition B from colliding with the vials and ensuring that the partition B will not bend.

[0024] like Figure 5As shown, the partition compartment 43 includes a left compartment plate 430 and a right compartment plate 431. A space is formed between the left compartment plate 430 and the right compartment plate 431 to accommodate a single partition B, and the left compartment plate 430 and the right compartment plate 431 can prevent the single partition B from tilting to the left or right.

[0025] After partition B is pushed out, due to the friction between partition B and the support part 4501 of pusher plate 450, pusher plate 450 may pull partition B back when it returns to its original position. To prevent this from happening, such as Figure 5 As shown, a check valve assembly is connected to the right compartment plate 431 (of course, a check valve assembly can also be installed on the left compartment plate 430; the effect is the same, and they are equivalent technical features). Figure 6 As shown, the check valve assembly includes a check valve seat 432, a check valve block 433, and a check valve spring 434. The check valve seat 432 is mounted on the right compartment plate 431 (the check valve seat 432 can be integrated with the right compartment plate 431). The check valve block 433 is movably mounted at the front end of the check valve seat 432, and the check valve spring 434 drives the check valve block 433 to move towards the left compartment plate 430. The side end of the check valve block 433 has an inclined surface 437 extending towards the left compartment plate 430. During the process of the partition being pushed out by the pusher plate 450, the partition acts on the inclined surface 437 of the check valve block 433, causing the check valve block 433 to move outward (e.g., ...). Figure 6 (As shown in the left direction), the check block 433 compresses the check spring 434. When the partition is pushed out, the check block 433 resets under the action of the check spring 434. The check block 433 then blocks the back side of the partition. When the push plate 450 resets, the check block 433 can prevent the partition B from being carried back, ensuring a stable supply of the partition.

[0026] To facilitate the installation of check block 433, such as Figure 6 As shown, the check block 433 is threadedly connected to the adjusting bolt 435. The bolt shank of the adjusting bolt 435 passes through the check seat 432, while the bolt head of the adjusting bolt 435 acts on the check seat 432. The check spring 434 is fitted onto the adjusting bolt 435, with one end of the check spring 434 acting on the check block 433 and the other end acting on the check seat 432. This structure makes it easier to install the check block 433 and to adjust its left and right positions, thereby adjusting the spring force.

[0027] In order to accommodate the pushing of partitions of different sizes, such as Figure 5As shown, a check valve 432 is movably and adjustablely mounted on the right compartment plate 431. The right compartment plate 431 has a right elongated hole. The check valve 432 is connected to the right compartment plate 431 by a right screw, which passes through the right elongated hole, thus allowing the check valve 432 to be adjusted forward and backward. Similarly, a left stop block 436 is provided on the left compartment plate 430. This left stop block 436 is movably and adjustablely mounted on the left compartment plate 430. The left compartment plate 430 has a left elongated hole. The left stop block 436 is connected to the left compartment plate 430 by a left screw, which passes through the left elongated hole, thus allowing the left stop block 436 to be adjusted forward and backward. This structure extends the length of the partition compartment 43, thereby accommodating the placement of longer partitions.

[0028] like Figure 3 As shown, a baffle 46 is provided at the front end of the partition compartment 43, such as... Figure 7 As shown, the baffle 46 has a discharge port 460 that communicates with the partition chamber 43. The discharge port 460 allows the pusher plate 450 to pass through. The baffle 46 can prevent the vial from colliding with mechanical parts such as the partition chamber 43 and the check valve assembly.

[0029] like Figure 4 As shown, two material magazines 42 are installed on the bracket 41. Each material magazine 42 corresponds to a partition unloading mechanism 44, each partition unloading mechanism 44 corresponds to a partition bin 43, and each partition bin 43 corresponds to a partition pushing mechanism 45; as Figure 3 As shown, the two partition unloading mechanisms 44 share a rotating guide plate 445 and a lifting power source 449; Figure 7 As shown, the two partition pushing mechanisms 45 share a single pushing power source 451. This structure can double the partition feeding efficiency.

[0030] To prevent excessive resistance in the partition pushing mechanism 45 from damaging the equipment, such as Figure 7As shown, the pusher plate 450 is connected to the overload protection seat 452, which is slidably mounted on the guide rail 454 of the pusher slide seat 453. The pusher power source 451 is connected to the pusher slide seat 453. A support seat 455 is mounted on the pusher slide seat 453. A connecting rod 456 is connected to the overload protection seat 452. The connecting rod 456 passes through the support seat 455 and is connected to the detection block 457. A spring 458 is sleeved on the connecting rod 456. The spring 458 is located between the support seat 455 and the overload protection seat 452. A photoelectric eye 459 that can detect the movement of the detection block 457 is mounted on the pusher slide seat 453. The photoelectric eye 459 is electrically connected to the controller, which controls the pusher power source 451 to work. During normal operation, the push power source 451 drives the pusher slide 453 to move forward. The pusher slide 453, along with the overload protection seat 452 and the pusher plate 450, moves forward together. Supported by the spring 458, the pusher plate 450 elastically pushes the partition forward. When there is a fault (such as the vial being mispositioned), the pusher plate 450 will act directly on the vial. In this case, the overload protection seat 452 will not move forward, while the pusher slide 453 continues to move forward. This causes the overload protection seat 452 to compress the spring 458, and the detection block 457 will move backward relative to the support seat 455. The photoelectric eye 459 detects the change in the position of the detection block 457 and sends a signal to the controller. The controller immediately controls the push power source 451 to stop outputting, thus achieving overload protection and protecting the equipment and materials from damage.

[0031] like Figure 10 As shown, this box-feeding device 7 includes a feeding mechanism, which includes a feeding rod 70 and a feeding power source 72 (linear module or existing motor drive mechanism) that drives the feeding rod 70 to move left and right. Driven by the feeding power source 72, the feeding rod 70 can move left and right. To achieve stable feeding, a top-feeding mechanism is provided opposite the feeding mechanism. This top-feeding mechanism includes a top-feeding rod 71 and a top-feeding power source 73 that drives the top-feeding rod 71 to move left and right. Driven by the top-feeding power source 73, the top-feeding rod 71 can move left and right. Figure 11 As shown, during operation, the arranged pharmaceutical glass bottles X are conveyed through the material conveying grid conveyor 5, and the cardboard boxes H are also conveyed through the cardboard box grid conveyor 6. Both the pharmaceutical glass bottles X and the cardboard boxes H are located between the pushing mechanism and the top-feeding mechanism. Figure 11 As shown, the top rod 71 first passes through the cardboard box H to the rear side of the pharmaceutical glass bottle X and abuts against the rear side of the pharmaceutical glass bottle X. The push rod 70 abuts against the front side of the pharmaceutical glass bottle X. The push rod 70 moves forward, and the top rod 71 moves backward at the same speed. In this way, the push rod 70, the pharmaceutical glass bottle X and the top rod 71 form a whole, which can stably push multiple rows of pharmaceutical glass bottles X into the cardboard box H together.

[0032] like Figure 10 As shown, pharmaceutical glass bottles X generally need to be packaged together with instruction manuals S into cardboard boxes H. Therefore, an instruction manual feeding device 8 is provided between the material grid conveying device 5 and the cardboard box grid conveying device 6. The instruction manual feeding device 8 includes an instruction manual feeding power source (not shown), a transmission chain 80, a transmission sprocket (not shown), and several instruction manual clips 81 (existing technology). The transmission chain 80 is wound around the transmission sprocket, and the instruction manual clips 81 are connected to the transmission chain 80. The instruction manual feeding power source is connected to the transmission sprocket. Driven by the instruction manual feeding power source, the transmission sprocket drives the transmission chain 80 to rotate, and the instruction manual clips 81 on the transmission chain 80 move the instruction manuals. Figure 11 As shown, when the instruction manual S and the pharmaceutical glass bottle X are in the same position, the push rod 70 acts on one side of the pharmaceutical glass bottle X, while the ejector rod 71 acts on one side of the instruction manual S. In this way, the push rod 70 and the ejector rod 71 can cooperate to move the pharmaceutical glass bottle X and the instruction manual S together into the cardboard box H on one side. Figure 11 As shown, because the top rod 71 acts on the instruction manual S, the instruction manual S is supported from the rear. When the instruction manual S enters the cardboard box H, it can bend more stably, thus entering the cardboard box more stably. (Without the support of the top rod 71, the position of the instruction manual S will be uncertain under the push of the pharmaceutical glass bottle X, which may result in the instruction manual S not being able to enter the cardboard box H.)

[0033] To improve feeding efficiency, the feeding mechanism includes two feeding rods 70 arranged horizontally and horizontally, while the ejecting mechanism includes two ejecting rods 71 ​​arranged horizontally and horizontally; each feeding rod 70 is positioned opposite to one ejecting rod 71. This allows two sets of material to be pushed in a single feeding operation, thus significantly improving feeding efficiency.

[0034] like Figure 12 As shown, the material grid conveyor 5 is used to convey pharmaceutical glass bottles X (such as vials), as... Figure 13 As shown, the carton grid conveyor 6 is used to convey carton (see prior art with patent publication number CN107902169A). The structure and working principle of the material grid conveyor 5 and the carton grid conveyor 6 are described in detail below.

[0035] like Figure 12As shown, the material grid conveying device 5 includes an active feeding sprocket 50 and a driven feeding sprocket 51. An active feeding chain is wound around the active feeding sprocket 50, and multiple first support members 53 are connected to the active feeding chain. A first grid plate 530 is mounted on each of the first support members 53. A driven feeding chain is wound around the driven feeding sprocket 51, and multiple second support members 52 are connected to the driven feeding chain. A second grid plate 520 is mounted on each of the second support members 52. A gap is formed between the first grid plate 530 and the second grid plate 520 to accommodate material. When the active feeding chain and the driven feeding chain move synchronously, normal feeding is achieved. When the active feeding chain is fixed and the driven feeding chain moves, the gap between the first grid plate 530 and the second grid plate 520 can be adjusted (see the prior art with announcement number CN211685866U), that is, material width adjustment is achieved.

[0036] In order to adjust the material width, such as Figure 14 As shown, a conveyor frame 9 is mounted on the frame 1, and a rotatable first transmission sleeve 54 is mounted on the conveyor frame 9, as... Figure 16 As shown, the first transmission sleeve 54 is equipped with a rotatable first transmission shaft 540. A driving feed sprocket 50 is connected to the first transmission sleeve 54, and a driven feed sprocket 51 is connected to the first transmission shaft 540. The driving feed sprocket 50 and the driven feed sprocket 51 are arranged side-by-side. Figure 15 As shown, a first harmonic drive reducer 55 is installed on the conveyor frame 9. The first harmonic drive reducer 55 includes a first harmonic drive shaft 550, a first left steel wheel 551, and a first right steel wheel 552. The first harmonic drive shaft 550 is rotatably mounted on the conveyor frame 9. A first adjusting power source 56 is installed on the conveyor frame 9 and is connected to the first harmonic drive shaft 550. The first left steel wheel 551 is connected to a first left gear 553. A first driven gear 542 is connected to the first drive shaft 540 and meshes with the first left gear 553. The first right steel wheel 552 is connected to a first right drive wheel 554. A drive shaft 57 is installed on the conveyor frame 9, and a first external drive wheel 59 is connected to the drive shaft 57. The first outer drive wheel 59 is connected to the first right drive wheel 554. The first driven drive wheel 541 is connected to the first drive sleeve 54. The first inner drive wheel 511 is connected to the drive shaft 57. The first inner drive wheel 511 is connected to the first driven drive wheel 541. The drive shaft 57 is connected to the power source 58 (through the drive belt 580 and the synchronous pulley 581).

[0037] The harmonic drive reducer is existing technology, which includes a wave generator, a flexible wave, and two steel wheels (refer to the existing technology with announcement number CN113700823A). The flexible wave is fitted onto the wave generator, and the two steel wheels are fitted onto the flexible wave. The external teeth on the flexible wave mesh with the internal teeth of the steel wheels (the two have a gear ratio). Its working characteristics are as follows: when the shaft drives the wave generator to rotate, the flexible wave can drive the steel wheels to rotate. When one of the steel wheels is fixed, the flexible wave can drive the other steel wheel to rotate. When the shaft is fixed to the wave generator, when one steel wheel rotates, the other steel wheel can be driven to rotate through the flexible wave.

[0038] The working principle of this material grid conveying device 5 during normal conveying is as follows: During normal conveying, such as Figure 14 As shown, the power source 58 drives the drive shaft 57, as... Figure 15 As shown, the rotation of the drive shaft 57 drives the first transmission sleeve 54 to rotate via the first inner transmission wheel 511 and the first driven transmission wheel 541. Since the drive feed sprocket 50 is connected to the first transmission sleeve 54, the drive feed sprocket 50 rotates, thereby driving the drive feed chain to move. Additionally, the rotation of the drive shaft 57 drives the first right steel wheel 552 to rotate via the first outer transmission wheel 59 and the first right transmission wheel 554. During normal conveying, the first regulating power source 56 does not output power, and the first harmonic drive reducer 55... The first harmonic drive shaft 550 does not rotate, so the rotation of the first right steel wheel 552 drives the first left steel wheel 551 to rotate through the soft wave. The rotation of the first left steel wheel 551 drives the first drive shaft 540 to rotate through the first left gear 553 and the first driven gear 542. Since the driven feeding sprocket 51 is connected to the first drive shaft 540, the driven feeding sprocket 51 rotates, thereby driving the driven feeding chain to move. Thus, the driven feeding chain and the active feeding chain move synchronously, which enables normal feeding.

[0039] The working principle of this material grid conveying device 5 during adjustment is as follows: When it is necessary to adjust the distance between the first grid plate 530 and the second grid plate 520, the conveying power source 58 stops conveying. Thus, the drive shaft 57 does not rotate, and the first transmission sleeve 54 and the drive feeding sprocket 50 connected to the first transmission sleeve 54 do not rotate. Since the drive shaft 57 does not rotate, the first outer transmission wheel 59 and the first right transmission wheel 554 do not rotate, and the first right steel wheel 552 also does not rotate. At this time, the first adjusting power source 56 outputs power, driving the first harmonic drive reducer 5. The first harmonic drive shaft 550 rotates, and the first harmonic drive shaft 550 drives the soft wave to rotate through the wave generator. The soft wave drives the first left steel wheel 551 to rotate. The rotation of the first left steel wheel 551 drives the first drive shaft 540 to rotate through the first left gear 553 and the first driven gear 542. Since the driven feeding sprocket 51 is connected to the first drive shaft 540, the driven feeding sprocket 51 rotates, thereby driving the driven feeding chain to move. This achieves the goal of fixing the active feeding chain and moving the driven feeding chain, thus realizing the adjustment of the material width.

[0040] like Figure 13 and Figure 14 As shown, the carton grid conveying device 6 includes an active feeding sprocket 60 and a driven feeding sprocket 61. An active feeding chain 62 is wound around the active feeding sprocket 60, and a first partition 620 is connected to the active feeding chain 62. A driven feeding chain 63 is wound around the driven feeding sprocket 61, and a second partition 630 is connected to the driven feeding chain 63. A gap for accommodating cartons is formed between the first partition 620 and the second partition 630. When the active feeding chain 62 and the driven feeding chain 63 move synchronously, normal carton feeding can be achieved. When the active feeding chain 62 is fixed and the driven feeding chain 63 rotates, the gap between the first partition 620 and the second partition 630 can be adjusted, that is, the carton width can be adjusted. The active box feeding sprocket 60 and the driven box feeding sprocket 61 form a group, with a total of two groups, left and right, which are symmetrically arranged. The paper box H is placed between the two first partitions 620 and the two second partitions 630 of the two groups.

[0041] In order to enable box width adjustment, such as Figure 14 As shown, a rotatable second transmission sleeve 64 is installed on the conveyor frame 9, such as... Figure 17 As shown, a rotatable second transmission shaft 640 is provided inside the second transmission sleeve 64. A driving box-feeding sprocket 60 is connected to the second transmission sleeve 64, and a driven box-feeding sprocket 61 is connected to the second transmission shaft 640. The driving box-feeding sprocket 60 and the driven box-feeding sprocket 61 are arranged side-by-side. Figure 14 As shown, a second harmonic drive reducer 68 is installed on the conveyor frame 9, such as... Figure 18As shown, the second harmonic drive reducer 68 includes a second harmonic drive shaft 680, a second left steel wheel 681, and a second right steel wheel 682. The second harmonic drive shaft 680 is rotatably mounted on the conveyor frame 9. A second adjusting power source 67 is mounted on the conveyor frame 9 and is connected to the second harmonic drive shaft 680. The second right steel wheel 682 is connected to the second right gear 684. A second driven gear 614 is connected to the second drive shaft 640 and meshes with the second right gear 684. The second left steel wheel 681 is connected to the second left drive wheel 683, which is connected to the conveying drive power source 58 via a drive belt 580. Figure 14 As shown, a second transmission wheel 641 is connected to the second transmission sleeve 64, and a first transmission wheel 571 is connected to the drive transmission shaft 57. The first transmission wheel 571 and the second transmission wheel 641 are connected in a transmission connection.

[0042] The working principle of this cardboard box grid conveyor 6 during normal conveying is as follows: During normal conveying, such as Figure 14 As shown, the active power source 58 drives the active drive shaft 57 to rotate. The rotation of the active drive shaft 57 drives the second drive sleeve 64 to rotate via the first drive wheel 571 and the second drive wheel 641. Since the active box feeding sprocket 60 is connected to the second drive sleeve 64, the active box feeding sprocket 60 rotates, and the active box feeding chain 62 rotates. The active power source 58 drives the second left drive wheel 683 via the drive belt 580. The second left drive wheel 683 drives the second left steel wheel 681 to rotate. At this time, the second regulating power source 67 does not output power, and the second harmonic drive... The second harmonic drive shaft 680 of the reducer 68 does not rotate. In this way, the second left steel wheel 681 drives the flexible wave to rotate, and the flexible wave drives the second right steel wheel 682 to rotate. The rotation of the second right steel wheel 682 drives the second drive shaft 640 to rotate through the second right gear 684 and the second driven gear 614. Since the driven box feeding sprocket 61 is connected to the second drive shaft 640, the driven box feeding sprocket 61 drives the driven box feeding chain 63 to rotate. This achieves synchronous movement of the active box feeding chain 62 and the driven box feeding chain 63, thus enabling normal box feeding.

[0043] The working principle of this cardboard box grid conveyor 6 during adjustment is as follows: When it is necessary to adjust the distance between the first partition 620 and the second partition 630, such as... Figure 14 As shown, when the conveying power source 58 stops conveying, the drive shaft 57 does not rotate, and there is no transmission between the first drive wheel 571 and the second drive wheel 641. Therefore, the second drive sleeve 64 does not rotate. Since the drive box feeding sprocket 60 is connected to the second drive sleeve 64, the drive box feeding sprocket 60 does not rotate, and the drive box feeding chain 62 does not rotate. Figure 18As shown, since the main power source 58 stops conveying, the second left drive wheel 683 does not rotate, and the second left steel wheel 681 does not rotate. At this time, the second regulating power source 67 outputs power, driving the second harmonic drive shaft 680 of the second harmonic drive reducer 68 to rotate. The rotation of the second harmonic drive shaft 680 drives the flexible wave to rotate, and the flexible wave drives the second right steel wheel 682 to rotate. The rotation of the second right steel wheel 682 drives the second drive shaft 640 to rotate through the second right gear 684 and the second driven gear 614. Since the driven box feeding sprocket 61 is connected to the second drive shaft 640, the driven box feeding sprocket 61 drives the driven box feeding chain 63 to rotate. Thus, the main box feeding chain 62 is fixed, while the driven box feeding chain 63 moves, thereby achieving the adjustment of the box width.

[0044] This adjustable grid conveyor only requires one main power source 58 (motor) to simultaneously drive the material grid conveyor 5 and the carton grid conveyor 6 for conveying. The two have better synchronization, lower cost, and can easily adjust the material width and carton width to meet the conveying needs of different specifications of materials and different specifications of cartons.

[0045] To achieve the transmission connection between the first transmission wheel 571 and the second transmission wheel 641, such as Figure 14 As shown, both the first transmission wheel 571 and the second transmission wheel 641 are bevel gears, and a first transmission rod 617 is provided between the first transmission wheel 571 and the second transmission wheel 641, as shown. Figure 15 As shown, one end of the first transmission rod 617 is connected to a first bevel gear 650, which meshes with the first transmission wheel 571, as follows. Figure 14 As shown, the other end of the first transmission rod 617 is connected to a second bevel gear 651, which meshes with the second transmission wheel 641. Thus, when the drive shaft 57 rotates, it drives the second transmission sleeve 64 to rotate via the first transmission wheel 571, the first bevel gear 650, the first transmission rod 617, the second bevel gear 651, and the second transmission wheel 641. Alternatively, the first transmission wheel 571 and the second transmission wheel 641 can be synchronous pulleys, connected by a synchronous belt.

[0046] To achieve the transmission connection between the first outer drive wheel 59 and the first right drive wheel 554, such as Figure 15 As shown, both the first outer drive wheel 59 and the first right drive wheel 554 are synchronous pulleys, connected by a first synchronous belt 590. This ensures that the first outer drive wheel 59 and the first right drive wheel 554 move synchronously and maintain the same direction of rotation. Alternatively, both the first outer drive wheel 59 and the first right drive wheel 554 can be gears, with an intermediate gear installed between them, allowing the three gears to mesh. This would also ensure that the first outer drive wheel 59 and the first right drive wheel 554 move synchronously and maintain the same direction of rotation.

[0047] To achieve the transmission connection between the first inner transmission wheel 511 and the first driven transmission wheel 541, such as Figure 15 As shown, both the first inner drive wheel 511 and the first driven drive wheel 541 are gears, and they are connected by a transition gear 543. Alternatively, the first inner drive wheel 511 and the first driven drive wheel 541 can be synchronous pulleys, which are connected by a synchronous belt.

[0048] Since the first harmonic drive reducer 55 has a deceleration effect, in order to counteract this deceleration effect, the reduction ratio of the first harmonic drive reducer 55 is the same as the speed increase ratio between the first left gear 553 and the first driven gear 542 (that is, the first harmonic drive reducer 55 has a deceleration effect, while the first driven gear 542 and the first left gear 553 have a speed increase effect, and the two just cancel each other out). In this way, the reduction ratio of the first harmonic drive reducer 55 can be eliminated, so that the rotational speed of the active feed sprocket 50 and the driven feed sprocket 51 is kept consistent.

[0049] Similarly, the reduction ratio of the second harmonic drive shaft 680 is the same as the speed increase ratio between the second right gear 684 and the second driven gear 614. This eliminates the reduction ratio of the second harmonic drive reducer 68, ensuring that the rotational speeds of the driving sprocket 60 and the driven sprocket 61 are consistent.
