[0002] With the continuous upgrading of technology in the ceramics industry, gradually replacing manual labor with mechanization and automation has become a development trend. Besides significantly reducing labor intensity, this approach also greatly improves work efficiency and quality.

[0003] Tile packaging machines are new products developed in response to this trend and tailored to the actual conditions of ceramic manufacturers in my country. Currently, many ceramic machinery manufacturers have launched various types of tile packaging machines. The packaging process typically involves: shaping, adding protective foam boards, adding corner protectors, packing, and folding and sealing the box.

[0004] However, most existing folding devices can only fold the four flaps on the top or bottom side of the carton, still requiring manual assistance. They cannot fold all eight flaps on both sides of the carton, thus affecting the subsequent sealing operation and consequently impacting the efficiency and quality of the carton packaging.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0048] This utility model provides a folding box device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0049] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0050] Please see Figures 1 to 8As shown, this utility model provides a carton folding device, comprising: a conveying mechanism 1, and a first folding mechanism 2, a second folding mechanism 3, a flipping mechanism 4, a third folding mechanism 5, and a fourth folding mechanism 6 arranged sequentially along the conveying direction of the conveying mechanism 1. The conveying mechanism 1 is used to convey cartons through the first folding mechanism 2 to the fourth folding mechanism 6. The first folding mechanism 2 is disposed on one side of the conveying mechanism 1 and is used to fold the left and right cover plates of the carton facing upward into the carton. The second folding mechanism 3 is disposed on the flipping mechanism 4 and can be adjusted accordingly. The flipping mechanism 4 flips the carton, and the second folding mechanism 3 folds the front and rear covers of the carton into the carton. The flipping mechanism 4 is set on the conveying mechanism 1 and is used to flip the folded side of the carton to the bottom, exposing the folded side as the new top side. The third folding mechanism 5 is set on the conveying mechanism 1 and is used to fold the left and right covers of the new top side of the carton into the carton. The fourth folding mechanism 6 is set on the conveying mechanism 1 and is used to fold the front and rear covers of the new top side of the carton into the carton.

[0051] In actual production, conveyor 1 transports the cartoned tile products to the first folding mechanism 2. The first folding mechanism 2 folds the left and right cover plates of the top-facing side of the carton. Then, conveyor 1 continues to transport the carton to the second folding mechanism 3, which folds the front and rear cover plates of the top-facing side. The folded carton and the tile products inside are then flipped by the flipping mechanism 4, so that the folded side of the carton faces upwards, and the folded side becomes the bottom. Conveyor 1 transports the flipped carton to the third folding mechanism 5, which folds the left and right cover plates of the top-facing side. Then, conveyor 1 continues to transport the carton to the fourth folding mechanism 6, which folds the front and rear cover plates of the top-facing side. Conveyor 1 then transports the fully folded carton to the sealing mechanism for tape application. This folding device can achieve fully automatic, all-around folding of the carton, completely replacing manual labor and improving packaging efficiency and quality.

[0052] Furthermore, in this embodiment, the first folding mechanism 2, the second folding mechanism 3, the third folding mechanism 5, and the fourth folding mechanism 6 are all equipped with positioning sensors. These sensors are used to identify the conveying position of the cartons on the conveying mechanism 1. The positioning sensors are connected to the overall control system in the production line, and the drive source for each mechanism is controlled by the overall control system. When the positioning sensor of a folding mechanism detects a carton, the overall control system controls the conveying mechanism 1 to pause its conveying action and controls that folding mechanism to begin folding. After the folding mechanism completes its folding action, the overall control system controls the conveying mechanism 1 to continue conveying. When the second folding mechanism 3 completes its folding action, the overall control system controls the flipping mechanism 4 to perform a flipping action, and then controls the conveying mechanism 1 to continue conveying. When the positioning sensor of the third folding mechanism 5 detects a carton, the overall control system does not control the conveying mechanism 1 to pause its conveying action, but only controls the third folding mechanism 5 to fold the carton.

[0053] Please see Figure 1 As shown, the conveying mechanism 1 includes a first conveying roller group 11, a second conveying roller group 12, a first conveyor belt 13, and a second conveyor belt 14. The first conveying roller group 11 is disposed corresponding to the first folding mechanism 2 and is used to convey the carton to be folded to the first folding mechanism 2 and the second conveying roller group 12. The second conveying roller group 12 is disposed on the flipping mechanism 4 and can be flipped with the flipping mechanism 4. The second conveying roller group 12 is used to convey the carton to be folded to the flipping mechanism 4. The first conveyor belt 13 is disposed between the flipping mechanism 4 and the third folding mechanism 5 and is used to convey the flipped carton to be folded to the third folding mechanism 5. The second conveyor belt 14 is disposed through the third folding mechanism 5 and the fourth folding mechanism 6 and is used to convey the carton to be folded to the fourth folding mechanism 6 and the next working stage.

[0054] In this embodiment, the first conveyor roller group 11, the second conveyor roller group 12, the first conveyor belt 13, and the second conveyor belt 14 are all existing structures. The first conveyor roller group 11, the first conveyor belt 13, and the second conveyor belt 14 are all fixedly mounted on the factory floor or other bearing surface used in the production line by a frame. The second conveyor roller group 12 is mounted on the flipping mechanism 4 and can flip with the flipping mechanism 4, preventing the ceramic tile products inside the carton from falling out of the unfolded side during the flipping process. It also avoids interfering with the flipping action of the flipping mechanism 4, allowing the carton containing ceramic tile products to be flipped stably and safely, achieving folding on the other side. The first conveyor belt 13 is a relatively wide single belt located in the middle. The seam between the front and rear covers of the folded carton is pressed onto this single belt, preventing the ceramic tile products from falling out and avoiding interference with the resetting of the folding flap 36 of the second folding mechanism 3. The second conveyor belt 14 is a thinner double belt located on both sides. The front and rear covers of the folded carton are pressed onto the double belts respectively, which can prevent the ceramic tile products from falling off and can also avoid interfering with the subsequent sealing mechanism applying tape to the joint between the front and rear covers of the carton.

[0055] Please see Figures 2 to 4 As shown, the first folding box mechanism 2 includes a first folding box cylinder 21, a first connecting rod 22, a first rotating shaft 23, a first swing arm 24, a first bearing seat 25, and a first folding box arm 26. The telescopic rod of the first folding box cylinder 21 is connected to one end of the first connecting rod 22, and the other end of the first connecting rod 22 is rotatably connected to one end of the first swing arm 24. One end of the first rotating shaft 23 is fixedly connected to the other end of the first swing arm 24, and the first rotating shaft 23 is rotatably mounted on the first bearing seat 25. One end of the first folding box arm 26 is fixedly connected to the other end of the first rotating shaft 23. In this embodiment, the end of the first folding arm 26 that contacts the carton is bent, so that the contact area between the first folding arm 26 and the carton is offset from the axis of the first folding arm 26. When the first folding arm 26 swings to fold the carton, the bent end reaches the position and contacts the carton first, which can reduce the swing angle of the first folding arm 26, i.e., reduce the rotation angle of the first rotating shaft 23, thereby shortening the drive stroke of the first folding cylinder 21, which is beneficial for the compact design of the first folding mechanism 2. The first bearing seat 25 is used to install the first rotating shaft 23 to support the rotation of the first rotating shaft 23. The first swing arm 24 swings at a specific angle with the axis of rotation of the first rotating shaft 23 as the axis of rotation. There are two of each of the first folding cylinder 21, the first connecting rod 22, the first rotating shaft 23, the first swing arm 24, the first bearing seat 25, and the first folding arm 26, which are symmetrically arranged to achieve simultaneous folding of the left and right cover plates of the carton.

[0056] In the actual folding process, the first conveyor roller group 11 conveys the carton to be folded to the first folding mechanism 2 and stops. The telescopic rod of the first folding cylinder 21 extends, driving the first movable rod 22 to move outward, thereby pushing the first swing arm 24 to swing. The first swing arm 24 drives the first rotating shaft 23 to rotate, and the first rotating shaft 23 drives the first folding arm 26 to swing. The bent end of the first folding arm 26 approaches the carton to be folded and folds the left and right cover plates of the carton. After folding the left and right cover plates of the carton, the telescopic rod of the first folding cylinder 21 retracts, and the transmission drives the first folding arm 26 to reset, waiting for the next folding.

[0057] Please see Figures 2 to 4 As shown, the first folding box mechanism 2 further includes a cylinder mounting base 27, an adjusting plate 28, a movable folding plate 29, a slider 210, a slide rail 211, a movable cylinder 212, and a first frame 213. The first folding box cylinder 21 is mounted on the cylinder mounting base 27, the cylinder mounting base 27 is mounted on the adjusting plate 28, the adjusting plate 28 is mounted on the movable folding plate 29, the first bearing seat 25 is mounted on the movable folding plate 29, the slider 210 is disposed on the movable folding plate 29, the slide rail 211 is disposed on the first frame 213, the movable cylinder 212 is disposed on the first frame 213 and drives the movable folding plate 29, and the slider 210 is slidably connected to the slide rail 211. The first folding box mechanism 2 also includes a foot plate 214, the first frame 213 is mounted on the foot plate 214, and the foot plate 214 is used to adjust the height of the first frame 213. In this embodiment, there are two cylinder mounting bases 27 and adjusting plates 28, which are symmetrically arranged. The first folding mechanism 2 is symmetrical about the vertical plane containing the central axis of the movable cylinder 212, and all the aforementioned two components are symmetrically arranged about this plane. The adjusting plate 28 and the movable folding plate 29 are connected by screws. The movable folding plate 29 is provided with an adjusting hole 291. By adjusting the position of the screw in the adjusting hole 291, the installation height of the adjusting plate 28 on the movable folding plate 29 is changed, thereby adjusting the installation height of the first folding cylinder 21.

[0058] Before the carton to be folded is conveyed to the first folding mechanism 2 by the conveying mechanism 1, the moving cylinder 212 drives the moving folding plate 29 to move forward along the slide rail 211. The moving folding plate 29 drives the first folding cylinder 21, the first folding arm 26 and other components mounted on it to move forward and approach the carton to be folded. When the first folding arm 26 is located on the front-rear center axis of the carton to be folded, the first folding cylinder 21 starts working, causing the first folding arm 26 to swing and fold the left and right cover plates of the carton to be folded inward, thus completing the folding of the left and right cover plates. After the first folding action is completed, the first folding arm 26 returns to its original position, and the moving cylinder 212 drives the moving folding plate 29 to move backward, thereby resetting the first folding cylinder 21 and other components so that the carton to be folded can be conveyed to the second folding mechanism 3 by the conveying mechanism 1.

[0059] Please see Figures 5 to 6 As shown, the second folding mechanism 3 includes a second folding cylinder 31, a second connecting rod 32, a second rotating shaft 33, a second swing arm 34, a second bearing seat 35, and a folding flap 36. The telescopic rod of the second folding cylinder 31 is connected to one end of the second connecting rod 32, and the other end of the second connecting rod 32 is rotatably connected to one end of the second swing arm 34. The other end of the second swing arm 34 is fixedly connected to one end of the second rotating shaft 33. The second rotating shaft 33 is rotatably mounted on the second bearing seat 35, and the other end of the second rotating shaft 33 is fixedly connected to the folding flap 36. In this embodiment, there are two of each of the following components: the second folding cylinder 31, the second connecting rod 32, the second rotating shaft 33, the second swing arm 34, the second bearing seat 35, and the folding flap 36. They are arranged symmetrically along the axis of the conveying direction to simultaneously fold the front and rear covers of the carton to be folded. The folding flap 36 includes a flipping base plate 361 and a pressure plate 362 disposed on the flipping base plate 361. The pressure plate 362 protrudes from the flipping base plate 361 on the side closest to the carton. When folding the carton, the pressure plate 362 first contacts the front cover and the rear cover of the carton, which can reduce the flipping angle of the folding flap 36, that is, reduce the rotation angle of the second rotating shaft 33, and maintain the angle between the folding flap 36 and the side wall of the carton at 90°, so that the ceramic tile products inside the carton can be flipped smoothly when the flipping mechanism 4 flips.

[0060] When folding the carton, the carton to be folded, whose left and right cover plates have already been folded by the first folding mechanism 2, is conveyed by the first conveyor roller group 11 into the second conveyor roller group 12. The telescopic rod of the second folding cylinder 31 retracts, causing the second movable rod 32 to move downward. The second movable rod 32 causes the second swing arm 34 to swing downward, thereby causing the second rotating shaft 33 to rotate, and finally causing the folding flap 36 to flip downward to fold the front and rear cover plates of the carton to be folded inward. It should be noted that after the second folding action is completed, the folding flap 36 does not immediately return to its original position, but maintains the posture of pressing down the front and rear cover plates of the carton, and then returns to its original position after being flipped in coordination with the flipping mechanism 4.

[0061] Please see Figures 5 to 6 As shown, the flipping mechanism 4 includes a second frame 41, a flipping frame 42, a flipping motor 43, a flipping shaft 44, a pressing member 45, and a pressing cylinder 46. The flipping frame 42 and the flipping motor 43 are both mounted on the second frame 41. The second folding cylinder 31, the second bearing seat 35, and the second conveying roller group 12 are all mounted on the flipping frame 42. The flipping motor 43 drives the flipping shaft 44, which is fixedly connected to the flipping frame 42 and drives the flipping frame 42 to flip. The pressing member 45 is movably connected to the flipping frame 42 and can move relative to it. The pressing cylinder 46 drives the pressing member 45. In this embodiment, the flipping motor 43 drives the flipping shaft 44 to rotate via a gear transmission structure. The flipping shaft 44 drives the flipping frame 42 to rotate 180° reciprocatingly, thereby flipping and swapping the top and bottom surfaces of the carton to be folded.

[0062] After the second folding mechanism 3 completes the second folding action, the pressing cylinder 46 drives the pressing member 45 to move upward from the bottom of the carton and extend into the carton to press against the ceramic tile product, so that the ceramic tile product presses against the folded left and right cover plates. The folding flip plate 36 keeps pressing against the front and rear cover plates of the carton, and the ceramic tile product is fixed inside the carton. The flipping motor 43 drives the flipping shaft 44 to rotate, and the flipping shaft 44 drives the flipping frame 42 to rotate 180°, so that the folded front, rear, left and right cover plates of the carton are pressed down by the ceramic tile product, while the folded side of the carton is facing up. The flipped carton falls onto the first conveyor belt 13. The second folding cylinder 31 drives the folding flip plate 36 to reset, and then the flipping motor 43 drives the flipping frame 42 to reset, thereby driving the second conveyor roller group 12 and the second folding mechanism 3 to reset.

[0063] Please see Figures 5 to 6As shown, the flipping frame 42 includes two side plates 421 and baffles 422 respectively connected to the two side plates 421. The two ends of the flipping shaft 44 are fixedly connected to the two side plates 421 respectively. The second conveying roller group 12 is fixedly connected to the two side plates 421 respectively. The second bearing seat 35 is installed on the side plate 421. The second folding cylinder 31 and the pressing cylinder 46 are both installed on the same side of the baffle 422. The baffle 422 is used to hold the flipped carton against the side plate. In this embodiment, the two side plates 421 are arranged parallel to each other on both sides of the second conveying roller group 12 and parallel to the conveying direction. The two ends of the baffle 422 are vertically fixedly connected to the two side plates 421 respectively. When not flipped, the baffle 422 is located at the end of the second conveying roller group 12. During the flipping process, the baffle 422 can support the carton and prevent the carton and ceramic tile products from falling off.

[0064] Please see Figures 5 to 6 As shown, the holding member 45 includes a plurality of parallel abutment members 451 and a connecting plate 452 for mounting the plurality of abutment members 451. The holding cylinder 46 drives and connects to the connecting plate 452. The plurality of abutment members 451 are respectively located between each of the conveying rollers of the second conveying roller group 12. The connecting plate 452 is connected to a first guide rod 453. A first guide sleeve 454 is movably sleeved on the first guide rod 453. The first guide sleeve 454 is fixedly installed on the baffle 422 and is located on the same side as the holding cylinder 46. In this embodiment, the abutment member 451 is a plate parallel to the baffle 422, and the plurality of abutment members 451 are arranged parallel to the connecting plate 452 and perpendicular to the connecting plate 452. In some other embodiments, the abutment member 451 can be a cylinder, and there are at least two abutment members 451 between each two adjacent conveying rollers. By setting the first guide rod 453 and the first guide sleeve 454 to provide guidance, the movement of the holding member 45 is made more stable.

[0065] After the second folding mechanism 3 completes the folding action, the holding member 45 is driven by the holding cylinder 46, and multiple abutting members 451 move upward from between the conveying rollers of the second conveying roller group 12 and extend into the carton, lifting the ceramic tile products in the carton to abut against the folded left and right cover plates, so that the ceramic tile products have no room to move in the carton, and avoid damage to the carton or ceramic tile products caused by other movements of the ceramic tile products when flipping.

[0066] Please see Figures 7 to 8As shown, the third folding mechanism 5 includes a third frame 51, a fixed folding plate 52, a third folding cylinder 53, a third connecting rod 54, a third rotating shaft 55, a third swing arm 56, a third bearing seat 57, and a second folding arm 58. The fixed folding plate 52, the third folding cylinder 53, and the third bearing seat 57 are all mounted on the third frame 51. The telescopic rod of the third folding cylinder 53 is connected to one end of the third connecting rod 54, and the other end of the third connecting rod 54 is rotatably connected to one end of the third swing arm 56. The other end of the third swing arm 56 is fixedly connected to the third rotating shaft 55. The second folding arm 58 is connected to the third rotating shaft 55. The second folding arm 58 and the fixed folding plate 52 cooperate to fold and flip the left and right cover plates of the carton. In this embodiment, the fixed folding plate 52 is positioned directly above the first conveyor belt 13, and is located behind the second folding arm 58 in the conveying direction. The end of the fixed folding plate 52 facing the beginning of the conveying direction is bent upwards, and the upturned part acts as a guide, allowing the right cover of the carton to fold smoothly into the carton when it contacts the fixed folding plate 52 during the conveying process. The shape of the end of the second folding arm 58 that contacts the carton is the same as that of the first folding arm 26. The second folding arm 58 is connected to the third rotating shaft 55 via an adjusting rod. One end of the adjusting rod is fixedly connected to the third rotating shaft 55, and the other end is provided with an adjusting hole 291 and connected to the second folding arm 58 by a screw. The distance between the bent end of the second folding arm 58 and the upturned end of the fixed folding plate 52 can be adjusted by adjusting the position of the screw in the adjusting hole 291, ensuring that the distance between the two is consistent with the left and right width of the carton when the second folding arm 58 is not in motion.

[0067] After the carton is flipped, the first conveyor belt 13 transports the carton to the second conveyor belt 14. The second conveyor belt 14 does not stop transporting the carton when it enters the third folding mechanism 5. At the moment when the right cover of the carton contacts the raised part of the fixed folding plate 52, the telescopic rod of the third folding cylinder 53 extends, driving the third movable rod 54 to swing the third swing arm 56, thereby driving the third rotating shaft 55 to rotate. This causes the second folding arm 58 to swing and push the left cover of the carton to fold into the carton. During the carton transport process, the right cover is held against the fixed folding plate 52 and folded into the carton. Then the carton is transported to the fourth folding mechanism 6.

[0068] Please see Figures 7 to 8As shown, the fourth folding box mechanism 6 includes a fourth folding box cylinder 61, a folding box push plate 62, a second guide rod 63, and a second guide sleeve 64. The fourth folding box cylinder 61 is mounted on the third frame 51 and drives the folding box push plate 62. The folding box push plate 62 is fixedly connected to the second guide rod 63. The second guide sleeve 64 is movably sleeved outside the second guide rod 63 and fixedly mounted on the third frame 51. In this embodiment, the end of the fixed folding plate 52 is very close to the beginning of the folding box push plate 62. There are two fourth folding box cylinders 61 and two folding box push plates 62, symmetrically arranged on both sides of the fourth folding box mechanism 6. Each side has two second guide rods 63 and two second guide sleeves 64 to enhance the stability of the folding box push plate 62.

[0069] When the carton completes the third folding action in the third folding mechanism 5, it is sent into the fourth folding mechanism 6 by the second conveyor belt 14. When the carton completely leaves the fixed folding plate 52, the fourth folding cylinder 61 drives the folding push plate 62 to move towards the middle of the fourth transmission belt, thereby folding the front cover and the rear cover of the carton inward, completing the fourth folding action.

[0070] In summary, this utility model comprises a conveying mechanism 1 and a first folding mechanism 2, a second folding mechanism 3, a flipping mechanism 4, a third folding mechanism 5, and a fourth folding mechanism 6 arranged sequentially along the conveying direction of the conveying mechanism 1. In actual production, conveyor 1 transports the cartoned tile products to the first folding mechanism 2. The first folding mechanism 2 folds the left and right cover plates of the top-facing side of the carton. Then, conveyor 1 continues to transport the carton to the second folding mechanism 3, which folds the front and rear cover plates of the top-facing side. The folded carton and the tile products inside are then flipped by the flipping mechanism 4, so that the folded side of the carton faces upwards, and the folded side becomes the bottom. Conveyor 1 transports the flipped carton to the third folding mechanism 5, which folds the left and right cover plates of the top-facing side. Then, conveyor 1 continues to transport the carton to the fourth folding mechanism 6, which folds the front and rear cover plates of the top-facing side. Conveyor 1 then transports the fully folded carton to the sealing mechanism for tape application. This folding device can achieve fully automatic, all-around folding of the carton, completely replacing manual labor and improving packaging efficiency and quality.
