[0001] The invention relates to the technical field of carton production, in particular to a carton turning machine for carton production. Background Art

[0002] In the carton production process, carton turners are an important conveying and turning equipment, which are widely used in carton packaging, warehousing and logistics. Most of the existing carton turners for carton production use fixed conveyor belts or chains to convey cartons, and use mechanical arms or turning mechanisms to turn cartons. However, this traditional carton turner has some obvious defects in practical applications: First, when the existing carton turning machine is conveying cartons, the friction between the conveyor belt or chain and the cartons is large, which easily causes the cartons to slip or flip during the conveying process, thereby affecting the stability and safety of the conveying. Especially in the case of high-speed conveying, this phenomenon of slipping or flipping is more significant, which brings great inconvenience to the production and transportation of cartons. Secondly, when the existing carton turning machines turn over the cartons, it is often difficult to avoid squeezing and damaging the carton flaps.

[0013] Compared with the prior art, it has the following beneficial effects: Through the linkage of the steering rod and the second gear, the pressure plate can rotate according to the position of the carton, and use the roller to slide in contact with the top of the carton, which greatly reduces the friction of the carton during transportation and avoids the carton from sliding or flipping due to the movement of the conveying parts, ensuring the stability and safety of the transportation process; the design of the pressure plate can be fine-tuned according to the size and shape of the carton to adapt to cartons of different specifications. This flexibility ensures the stability of the carton during transportation.

This design not only simplifies the operation process, but also improves the reliability and durability of the equipment.

[0014] By starting the drive motor, the carton can automatically and continuously complete the flipping action, reducing the need for manual operation and significantly improving the automation level and operating efficiency of the production line; the intermittent rotation design of the driving wheel and the driven wheel allows for more precise control of the flipping process, ensuring that the carton can smoothly and accurately complete the flipping action and avoid collision or damage during the flipping process; when the flipping frame rotates upward by 90 degrees, the carton is closer to the inside of the flipping frame due to its own gravity and the inward movement of the push plate, which helps to maintain the stability of the carton during the flipping process and prevent it from slipping or improper flipping; through the coordinated action of the first gear, rotating rod, disc and connecting rod and other mechanisms, the carton can automatically adjust its position during the flipping process to ensure that it can be smoothly discharged by the conveyor after the flipping is completed, reducing the need for manual intervention.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: Combination Figure 1-Figure 9 As shown, the present invention provides a technical solution: a carton turning machine for carton production, comprising a frame 1, a turning assembly 2 is installed on the top of the frame 1, and both sides of the turning assembly 2 are equipped with conveying members 3 for conveying and turning over cartons. The conveying member 3 on the left is responsible for conveying the carton to the side of the turning assembly 2, and the conveying member 3 on the right is responsible for conveying and discharging the turned carton. In order to ensure that the position of the carton is accurate during the conveying process, a control assembly 4 is arranged above the conveying member 3 on the left; The control assembly 4 is composed of multiple parts. First, there is a support frame 41 fixedly mounted on the left side of the frame 1. A positioning rod 42 is fixedly connected to the support frame 41. A pressing plate 43 is rotatably connected to the positioning rod 42. The outer wall of the bottom end of the pressing plate 43 is fixedly connected to an arc plate 48. A roller is provided at the inner side of the pressing plate 43 for moving the carton. When the pressing plate 43 rotates inwardly with the positioning rod 42 as the axis, that is, when the upper end of the pressing plate 43 rotates downward, the roller at its inner side contacts and slides with the top of the carton. In this way, when the conveying member 3 conveys the carton, the pressing plate 43 cooperates with the roller to ensure that the carton can move stably and avoid instability during the conveying process. The middle part of the support frame 41 is rotatably connected to a steering rod 44, to which a guide rod 45 for correcting the position of the carton is fixedly connected, and the outer end of the support frame 41 is fixedly connected to a side plate 46, to which a center plate 47 for folding the swing cover of the carton is rotatably provided; The bottom end of the support frame 41 is fixedly connected to the slide bar 411, and the slide bar 411 is slidably connected to the moving frame 412. The outer end of the moving frame 412 is fixedly connected to the first gear rod 415. The right side of the moving frame 412 is provided with a second damping spring 413 sleeved on the slide bar 411. When the carton pushes the guide rods 45 on both sides to rotate about the axis of the steering rod 44 toward the front and rear support frames 41, that is, the guide rods 45 on the two steering rods 44 are unfolded with the steering rod 44 as the axis as the push of the carton, and at the same time, the guide rods 45 will drive the steering rod 44 to rotate about itself as the axis when unfolding. The steering rod 44 drives the second gear 416 to rotate, and the rotation of the second gear 416 can drive the first gear rod 415 and the moving frame 412 to move to one side and compress the second damping spring 413. When the carton is separated from the guide rod 45, the moving frame 412 and the first gear rod 415 are reset under the elastic force of the second damping spring 413. The outer end of the moving frame 412 is fixedly connected to the limiting rod 414, and the limiting rod 414 contacts the outer wall of the arc plate 48. The limiting rod 414 is tilted to limit the arc plate 48 to prevent the arc plate 48 from rotating. The upper and lower ends of the steering rod 44 are respectively fixedly connected to the third gear 417 and the second gear 416, and the second gear 416 is meshedly connected with the first gear rod 415. When the second gear 416 rotates, it can drive the first gear rod 415 to move; A connecting piece 49 is provided at the inner end of the arc plate 48, and a first damping spring 410 is provided between the connecting piece 49 and the support frame 41. Under the elastic force of the first damping spring 410, the connecting piece 49 is cooperated to push the arc plate 48 and the pressure plate 43 to rotate. When the position of the limit rod 414 does not change, that is, the position of the limit rod 414 is fixed, since the pressure plate 43 is rotatably installed on the positioning rod 42, the elastic force of the first damping spring 410 can push the connecting piece 49 to move outward, so that the connecting piece 49 drives the arc plate 48 to move synchronously, and then the arc plate 48 drives the pressure plate 43 to rotate at the positioning rod 42, so that the arc plate 48 contacts the limit rod 414. The limiting rod 414 limits the arc plate 48, and when the steering rod 44 drives the second gear 416 to rotate, the second gear 416 drives the meshing first gear rod 415, the moving frame 412 and the limiting rod 414 to move synchronously. Due to the inclined setting of the limiting rod 414, when the limiting rod 414 moves toward the second damping spring 413, the elastic force of the first damping spring 410 pushes the connecting piece 49 and the arc plate 48 to move outward, so that the arc plate 48 always keeps in contact with the limiting rod 414, and when the limiting rod 414 moves toward the center plate 47, the limiting rod 414 can push the arc plate 48 and the connecting piece 49 to move inward and compress the first damping spring 410. The outer end of the side plate 46 is transversely fixedly connected to the second gear rod 418 meshing with the third gear 417, the outer end of the second gear rod 418 is fixedly connected to the U-shaped frame 419, the end of the U-shaped frame 419 is fixedly connected to the slider 421, and one end of the center plate 47 is rotatably mounted on the slider 421 through a rotating shaft, and the two ends of the rotating shaft are fixedly connected to the fourth gear 422, the outer end of the side plate 46 is fixedly connected to the fixed blocks 420 on both sides, the surfaces of the two fixed blocks 420 are provided with a slide groove, the slider 421 is slidably installed in the slide groove, and the outer end of the fixed block 420 is fixedly connected to the third gear rod 423 meshing with the fourth gear 422 When the carton pushes the guide rods 45 on both sides to rotate toward the front and rear support frames 41 with the steering rod 44 as the axis, the guide rod 45 will drive the steering rod 44 to rotate with itself as the axis, so that the rotating steering rod 44 can drive the third gear 417 to rotate synchronously, so that the third gear 417 drives the meshing second gear rod 418 and U-shaped frame 419 to move to one side, so that the U-shaped frame 419 drives the slider 421, the fourth gear 422, and the center plate 47 located on the fixed block 420 to move inward. At the same time, since the fourth gear 422 is meshed with the third gear rod 423, the center plate 47 rotates inward.

[0019] In the embodiment of the present invention, when the carton pushes the guide rods 45 on both sides to rotate toward the front and rear support frames 41 with the steering rod 44 as the axis, the guide rods 45 will drive the steering rods 44 to rotate with themselves as the axis, so that the rotating steering rods 44 can drive the second gear 416 to rotate synchronously, and this rotation not only drives the rotation of the second gear 416, but also through the gear transmission mechanism, the rotation of the second gear 416 can further drive the first gear rod 415, the moving frame 412 and the limiting rod 414 to move to one side. In this process, the second damping spring 413 is compressed, thereby allowing the limiting rod 414 to no longer block the arc plate 48. Due to the force of the first damping spring 410, the arc plate 48 and the pressure plate 43 will rotate accordingly. This design ensures that the pressure plate 43 can rotate inwardly, and the roller shaft at its inner end contacts and slides with the top of the carton, thereby effectively reducing the friction of the carton during transportation. This design not only reduces friction, but also prevents the carton from sliding or flipping due to the movement of the conveying member 3, ensuring the stability and safety of the conveying process. When the conveying member 3 conveys the carton, the cooperation between the pressing plate 43 and the roller can make the carton move smoothly, preventing instability during the conveying process. In addition, the design of the pressing plate 43 also takes into account the support and positioning of the carton. During the conveying process of the carton, the pressing plate 43 can be fine-tuned according to the size and shape of the carton to adapt to cartons of different specifications, ensuring the stability of the carton during the conveying process. At the same time, the roller design on the pressing plate 43 can also reduce damage to the surface of the carton and protect the integrity of the carton. At the same time, when the guide rod 45 drives the steering rod 44 to rotate, the third gear 417 will also rotate accordingly, and this rotation will drive the second gear rod 418 and the U-shaped frame 419 meshing therewith to move to one side, and the movement of the U-shaped frame 419 will further drive the slider 421, the fourth gear 422 and the center plate 47 to move inward relative to the fixed block 420. Since the fourth gear 422 is meshed with the third gear rod 423, the center plate 47 will rotate at the same time during the process of moving inward. This rotation enables the center plate 47 to drive the swing cover of the carton to rotate inward during the process of rotating inward, thereby preventing the swing cover from being squeezed when the turning assembly 2 turns the carton, causing deformation or damage to the carton; When the carton is detached from the guide rod 45, the movable frame 412, the limit rod 414 and the first gear rod 415 are reset under the elastic force of the second damping spring 413. This reset process enables the limit rod 414 to drive the arc plate 48 and the pressure plate 43 to move and reset, thereby enabling the guide rod 45 and the centering plate 47 to move and reset, and return to the initial state, preparing for the next carton transportation.

[0020] Embodiment 2: Combination Figure 2 , Figure 3 , Figure 4 As shown, on the basis of the first embodiment, the flip assembly 2 includes a driving shaft 21 rotatably mounted on the frame 1, a driving member is provided at one end of the driving shaft 21, connecting frames 22 are fixedly connected to both sides of the driving shaft 21, the connecting frames 22 are fixedly connected to the flip frame 23 around, and the inner end of the flip frame 23 is slidably connected to the push plate 24; The inner ends of the turning frame 23 are rotatably connected to a rotating rod 25, the outer end of the rotating rod 25 is fixedly connected to a first gear 26, and the inner end is fixedly connected to a disk 27, the inner end of the disk 27 is rotatably connected to a connecting rod 28, the other end of the connecting rod 28 is rotatably connected to a push rod 29, and the other end of the push rod 29 is rotatably connected to the push plate 24; The driving member includes a driving motor 210 fixedly mounted on the frame 1, the output end of the driving motor 210 is fixedly connected to a driving wheel 211, and a driven wheel 212 adapted to the driving wheel 211 is provided on the side of the driving shaft 21 close to the driving motor 210. When the driving wheel 211 rotates, it can drive the driven wheel 212 to intermittently rotate ninety degrees, thereby facilitating the subsequent flipping of the carton; Gear rings 213 fixedly mounted on the frame 1 are provided on both sides of the driving shaft 21 , and the first gear 26 is meshedly connected with the gear rings 213 .

[0021] In the embodiment of the present invention, the conveying member 3 is responsible for conveying the carton to the position of the turning frame 23. Once the carton needs to be turned over, the system will start the driving motor 210. The start of the driving motor 210 will drive the driving wheel 211 connected thereto to rotate synchronously. As the driving wheel 211 rotates, it will mesh with the driven wheel 212, so that the driven wheel 212 starts to rotate intermittently. This intermittent rotation is finally transmitted to the turning frame 23 through a series of mechanical transmission mechanisms, including the connecting frame 22 and the turning frame 23, thereby realizing the turning action of the carton. When the turning frame 23 performs a ninety-degree upward turning, the rotating rod 25 and the first gear 26 will rotate synchronously. With the cooperation of the gear ring 213, the first gear 26 will rotate along the track of the gear ring, and at the same time drive the rotating rod 25 and the disc 27 to rotate together. The rotation of the disc 27 will be mechanically connected to the connecting rod 28, so that the connecting rod 28 will produce corresponding movement, and this movement will be further transmitted to the push rod 29 and the push plate 24, so that they move inward. Since the carton is affected by its own gravity when the turning frame 23 turns upward, it will move inward with the movement of the turning frame 23, ensuring that the carton can remain stable during the turning process; When the flip frame 23 performs a ninety-degree downward flip, the first gear 26 will also rotate along the trajectory of the ring gear 213, but this time it will drive the rotating rod 25 and the disk 27 to rotate in opposite directions. The reverse rotation of the disk 27 is transmitted to the push rod 29 and the push plate 24 through the connecting rod 28, causing them to move outward. The outward movement of the push plate 24 helps to push the carton from the flip frame 23, making it easier for the conveyor 3 to discharge the flipped carton out of the system. The whole process ensures the stability and accuracy of the carton during the flipping process through precise mechanical design and transmission mechanism, and also ensures that the conveyor 3 can efficiently complete the task of conveying and discharging the carton.

[0022] Working principle of carton turning machine for carton production: Step 1. After the carton is moved onto the conveying member 3, the conveying member 3 is used to convey it to the side of the control component 4, so that the carton pushes the guide rods 45 on both sides to rotate about the axis of the steering rod 44 toward the side of the front and rear support frames 41, that is, the guide rods 45 on the two steering rods 44 are unfolded with the steering rod 44 as the axis as the push of the carton, and at the same time, the guide rods 45 will drive the steering rod 44 to rotate about itself as the axis when unfolding, so that the steering rod 44 drives the second gear 416 to rotate, and the rotation of the second gear 416 can drive the first gear rod 415, the moving frame 412, and the limiting rod 414 to move to one side, and compress the second damping spring 413, so that the limiting rod 414 no longer forms a block to the arc plate 48, and the arc plate 48 and the pressure plate 43 rotate under the elastic force of the first damping spring 410, so that the pressure plate 43 rotates inwardly, and the roller shaft at the inner end of the pressure plate 43 is The top of the carton contacts and slides, so that when the conveying member 3 conveys the carton, the pressing plate 43 cooperates with the roller shaft to enable the carton to move, thereby preventing the conveying member 3 from being unstable when moving the carton; and when the guide rod 45 drives the steering rod 44 to rotate outward, it can drive the third gear 417 to rotate, so that the third gear 417 drives the meshing second gear rod 418 and U-shaped frame 419 to move to one side, so that the U-shaped frame 419 drives the slider 421, the fourth gear 422, and the centering plate 47 located on the fixed block 420 to move inward, and at the same time, because the fourth gear 422 is meshed with the third gear rod 423, the centering plate 47 rotates inward, so that the centering plate 47 can drive the swing cover of the carton to rotate inward during the inward rotation process, thereby preventing the swing cover from being squeezed when the flip assembly 2 flips the carton, causing the carton to be deformed or damaged; Step 2: Turn on the driving motor 210 to drive the driving wheel 211 to rotate synchronously, and the driving wheel 211 drives the driven wheel 212 to rotate intermittently, so that the driven wheel 212 drives the driving shaft 21, the connecting frame 22, and the turning frame 23 to rotate, thereby driving the carton to turn over; At the same time, when the overturning frame 23 rotates upward by 90 degrees, it can drive the rotating rod 25 and the first gear 26 to rotate synchronously, so that the first gear 26 rotates along the gear ring 213, so that the first gear 26 drives the rotating rod 25 and the disk 27 to rotate, and the disk 27 drives the linkage rod 28 to move, so that the linkage rod 28 drives the push rod 29 and the push plate 24 to move inwardly. This makes it possible for the overturning frame 23 to drive the carton to rotate upward, and the carton moves toward the inside of the overturning frame 23 under the action of its own gravity. When the overturning frame 23 rotates downward by 90 degrees, the first gear 26 can rotate along the gear ring 213, so that the first gear 26 drives the rotating rod 25 and the disk 27 to rotate, and the disk 27 drives the linkage rod 28 to move, so that the linkage rod 28 drives the push rod 29 and the push plate 24 to move outward, so that the push plate 24 can push the carton outward, so as to facilitate the conveying member 3 to discharge the carton; Step three, when the carton is separated from the guide rod 45, the movable frame 412, the limit rod 414, and the first gear rod 415 are reset under the elastic force of the second damping spring 413, so that the limit rod 414 drives the arc plate 48 and the pressure plate 43 to move and reset, and then the guide rod 45 and the centering plate 47 are moved and reset.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
