[0001] The present invention relates to the technical field of corrugated paper roll production, and specifically relates to an automatic conveying device for packing corrugated paper rolls. Background Art

[0002] In the production process of corrugated cardboard, the raw material conveying of paper rolls is a key link affecting the production line efficiency and safety. There are risks of axial offset and circumferential rolling of paper rolls in traditional roller conveyors. Due to its modular bearing surface and directional drive characteristics, the chain conveyor has gradually become the mainstream solution for heavy paper roll conveying.

[0003] The authorized announcement number CN210854003U discloses a paper roll conveying device for corrugated cardboard production, which relates to the field of corrugated paper production equipment, including a horizontal conveying line and a vertical conveying line. A first guiding plate is arranged at the output end of the horizontal conveying line, and horizontal baffles are arranged on both sides above the horizontal conveying line. A second guiding plate and a third guiding plate are arranged at the input end of the vertical conveying line, and vertical baffles are arranged on both sides above the vertical conveying line. A reversing table is arranged between the first guiding plate and the second guiding plate. A limiting column is arranged on the reversing table, and an upward pushing oil cylinder is arranged at the bottom of the limiting column. A rotating device is arranged at the center of the reversing table, and a flexible rubber pad is arranged on the top surface of the rotating device. A pushing plate opposite to the vertical conveying line is arranged on the reversing table, and two horizontally symmetrically distributed horizontal driving oil cylinders are arranged on the side of the pushing plate facing away from the vertical conveying line. This device is reasonably designed, simple in structure, good in connection performance, high in conveying efficiency and safe. It is suitable for large-scale promotion. This utility model conveys corrugated paper rolls through a conveying line. Since the conveying plate on the conveying line is flat, the conveying line will shake when conveying the paper roll, which will seriously cause the rolling of the paper roll. And when the conveying line conveys the paper roll, the weight of the paper roll will be transmitted to the chain through the conveying plate, making the chain bear a large pressure and reducing the service life of the chain.

[0024] Please refer to Figure 1 , the present invention provides an embodiment: an automatic conveying device for corrugated paper roll packing, including: a frame 100, a support leg 200 for adjusting stability is fixedly installed at the bottom of the frame 100, a conveying mechanism 400 for conveying the paper roll is fixedly installed inside the frame 100 through a chain, and a driving mechanism 300 for providing driving force for the conveying mechanism 400 is installed on the side of the frame 100; It should be noted that when in use, the paper roll is placed on the conveying mechanism 400 through a lifting device. The conveying mechanism 400 can limit the paper roll through components. After the paper roll is placed, the driving mechanism 300 works to drive the rotating rollers, gears and chains inside the frame 100 to work. When the chain works, it can drive the conveying mechanism 400 to rotate. When the conveying mechanism 400 rotates, it can convey the paper roll, and the height can also be adjusted through the support leg 200 at the bottom of the frame 100.

[0025] As Figure 1 and Figure 2 shown, the conveying mechanism 400 includes a placing component 410 for placing the paper roll, a limiting component 420 for limiting the paper roll, and a supporting component 430 for supporting the placing component 410. The placing component 410 is installed inside the frame 100 through a chain, the limiting component 420 is installed on the placing component 410, and the supporting component 430 is movably installed on the side of the frame 100; It can be conceived that when the paper roll is placed on the placing component 410, the placing component 410 can be recessed downward according to the diameter of the paper roll, so as to be adaptively adjusted according to the diameter of the paper roll. When the placing component 410 is recessed downward, the limiting component 420 can limit the paper roll to prevent the paper roll from swinging left and right. While the placing component 410 is recessed downward, the supporting component 430 supports the other non-recessed components of the placing component 410 through the cooperation of components.

[0026] As Figures 1-4 and Figure 6 shown, the storage assembly 410 includes a first placement seat 412 and a second placement seat 413 for placing paper rolls, and a connection seat 411 for mounting the first placement seat 412 and the second placement seat 413. The connection seat 411 is fixedly installed inside the frame 100 through a chain. The first placement seat 412 is installed on the side of the connection seat 411, and the second placement seat 413 is movably installed between the first placement seats 412; It should be noted that when the paper roll is placed, it will first contact the upper surface of the second placement seat 413. The weight of the paper roll will press down on the second placement seat 413. When the second placement seat 413 moves down to a specified position, it can drive the first placement seats 412 on both sides to move down through the cooperation of components. When the first placement seat 412 moves down to a specified position, it will drive the first placement seat 412 on the side to continue to move down. The second placement seat 413 and the first placement seat 412 can move down gradually according to the weight of the paper roll, so as to be adjusted to fit the diameter of the paper roll.

[0027] As Figures 2-6 shown, the storage assembly 410 further includes a groove 418 and a protrusion 419 for guiding the first placement seat 412 and the second placement seat 413, and an operation slot 414, a guide rod 415, a moving plate 416 and a pull rope 4110 for limiting the first placement seat 412 and the second placement seat 413. Grooves 418 are provided on one side of the connection seat 411 and the first placement seat 412. Protrusions 419 are fixedly installed on the side of the first placement seat 412 and the second placement seat 413 close to the groove 418. An operation slot 414 is provided inside the groove 418. Two guide rods 415 are symmetrically fixed inside the operation slot 414. A moving plate 416 is movably connected to the outer surface of the two guide rods 415. One end of a pull rope 4110 is fixedly connected to one side of the moving plate 416, and the other end of the pull rope 4110 is fixedly connected to the surface of the protrusion 419; It should be understood that when the second placement seat 413 and the first placement seat 412 move down, they can drive the protrusion 419 to slide down in the groove 418. When the protrusion 419 slides, it can pull one end of the pull rope 4110. When one end of the pull rope 4110 is pulled, the other end can drive the moving plate 416 to slide in the operation slot 414. When the moving plate 416 slides, it can slide on the outer surface of the guide rod 415. When the moving plate 416 slides to one end of the guide rod 415, the pull rope 4110 can drive the first placement seat 412 to move down through the moving plate 416.

[0028] As Figures 2-5As shown, the storage component 410 further includes a first spring 417 for resetting the first placement seat 412 and the second placement seat 413. One end of the first spring 417 is fixedly connected to the other side of the moving plate 416, and the other end of the first spring 417 is fixedly installed on the inner wall of the operation groove 414; It can be conceived that when the moving plate 416 moves, it can stretch one end of the first spring 417. When the paper roll is separated from the first placement seat 412 and the second placement seat 413, the first spring 417 can drive the moving plate 416 to reset through its own elastic force. When the moving plate 416 resets, it can drive the first placement seat 412 and the second placement seat 413 to reset through the pull rope 4110.

[0029] Such as Figures 2-4 and Figure 6 As shown, the limiting component 420 includes a limiting plate 421 for limiting the paper roll and a placement groove 422 for installing the limiting plate 421. A placement groove 422 is opened on one side of the first placement seat 412. Limiting plates 421 matching the placement groove 422 are fixedly installed on the side surfaces of the connecting seat 411 and the first placement seat 412, and inclined surfaces are provided on the limiting plates 421; It should be noted that when the first placement seat 412 moves downward, it will drive the placement groove 422 to move downward. When the first placement seat 412 moves to a specified position, the limiting plate 421 will slide out of the placement groove 422. After the limiting plate 421 slides out of the placement groove 422, it will be arranged staggered on the side surface of the first placement seat 412. The limiting plate 421 can limit the paper roll through its own inclined surface, thereby avoiding the left and right swing of the paper roll during transportation.

[0030] Such as Figures 2-4 and Figure 6 As shown, the limiting component 420 further includes an anti-slip pad 424 for increasing the friction of the paper roll and a fixing groove 423 for installing the anti-slip pad 424. A number of fixing grooves 423 are equidistantly opened on the limiting plate 421, and an anti-slip pad 424 is installed inside each fixing groove 423; It can be conceived that when the limiting plate 421 moves out of the placement groove 422, it will drive the anti-slip pad 424 to move. When the limiting plate 421 limits the paper roll, it will drive the anti-slip pad 424 to fit with the paper roll. The anti-slip pad 424 can increase the friction with the paper roll through its own rubber material.

[0031] Such as Figures 2-5 and Figure 7As shown, the support assembly 430 includes a support rod 4313, a support base 4314, and a support pulley 4315 for supporting the first placement seat 412, as well as a connecting frame 431, a mounting groove 439, a moving block 4311, and a moving frame 4312 for moving the support rod 4313. The surface of the connecting seat 411 is movably connected to the connecting frame 431 through a through hole. The connecting frame 431 is provided with a mounting groove 439. A moving frame 4312 is sleeved on the outer surface of the connecting frame 431. A moving block 4311 is fixedly connected to the inner side of the moving frame 4312 close to the mounting groove 439. A support rod 4313 is fixedly installed on the moving frame 4312. A support base 4314 is fixedly installed at the top of the support rod 4313. A support pulley 4315 is rotatably installed on the top of the support base 4314 through an assembly groove; It should be noted that when the moving block 4311 is pushed, it can slide inside the mounting groove 439. When the moving block 4311 slides, it will drive the moving frame 4312 to move. When the moving frame 4312 moves, it can slide on the outer surface of the connecting frame 431. When the moving frame 4312 slides, it can drive the support rod 4313 to move. When the support rod 4313 moves, it can drive the support base 4314 and the support pulley 4315 to move. When the support pulley 4315 moves, it can slide and support the bottom of the first placement seat 412. The initial position of the support pulley 4315 is located at the bottom of the first placement seat 412 adjacent to the second placement seat 413. When the second placement seat 413 moves down to a specified position, the second placement seat 413 can move the support pulley 4315 from the bottom of the first placement seat 412 to the bottom of the other first placement seat 412 through the cooperation of components. Thus, the support pulley 4315 can slide and support the first placement seats 412 at different positions as the second placement seat 413 gradually moves down.

[0032] As Figures 1-4 As shown, the support assembly 430 further includes a guide pulley 4316 and a guide annular groove 4317 for moving the connecting frame 431. Guide pulleys 4316 are rotatably installed at both ends of the connecting frame 431. Two guide annular grooves 4317 matching the guide pulleys 4316 are symmetrically provided on the inner side of the frame 100; It should be understood that when the chain rotates, it can drive the connecting seat 411 to move. When the connecting seat 411 moves, it drives the connecting frame 431 to move through the assembly groove. When the connecting frame 431 moves, it can drive the guide pulley 4316 to move. When the guide pulley 4316 moves, it can slide in the guide annular groove 4317. When the support pulley 4315 supports the connecting seat 411 and the first placement seat 412, the pressure will be applied to the connecting frame 431. The connecting frame 431 will then apply the pressure to the frame 100 through the guide pulley 4316 and the guide annular groove 4317, thereby reducing the wear of the chain during use and increasing the service life of the chain.

[0033] As Figures 2-5 shown, the support assembly 430 further includes a connecting column 432 for applying a driving force to the support pulley 4315, an extrusion chamber 433, a push rod 434, a docking groove 435 and a piston 436, and a second spring 437 for resetting the support pulley 4315. A connecting column 432 is fixedly installed at the center of the connecting frame 431. An extrusion chamber 433 is opened at the top end of the connecting column 432. The end of the extrusion chamber 433 is located inside the connecting frame 431. A docking groove 435 is opened at the bottom of the second placement seat 413. A push rod 434 is fixedly installed at the center of the top of the docking groove 435. A piston 436 is fixedly installed at the end of the push rod 434. The piston 436 is movably connected inside the extrusion chamber 433; It can be conceived that when the second placement seat 413 moves downward, it can drive the docking groove 435 to move downward. When the docking groove 435 moves downward, it can push the push rod 434 to move downward. When the push rod 434 moves downward, it can push the piston 436. When the piston 436 is pushed, it can slide inside the extrusion chamber 433. When the piston 436 moves inside the extrusion chamber 433, it can squeeze the gas inside downward. When the gas is squeezed downward, it can drive the support seat 4314 and the support pulley 4315 to move through the cooperation of components. When the paper roll moves out of the surface of the second placement seat 413, the piston 436 can be reset by the elastic force of the second spring 437 itself. When the piston 436 is reset, it can push the second placement seat 413 to reset through the push rod 434.

[0034] As Figures 2-5 and Figure 7 shown, the support assembly 430 further includes a telescopic member 4310 for pushing the moving block 4311 to move, and an air inlet hole 438 for delivering gas to the telescopic member 4310. An air inlet hole 438 is penetrated between the installation groove 439 and the extrusion chamber 433. A telescopic member 4310 is fixedly installed at one end of the installation groove 439 close to the air inlet hole 438. The telescopic member 4310 is connected to the air inlet hole 438; It should be noted that when the piston 436 moves inside the extrusion chamber 433, it can squeeze the gas inside downward. When the gas is squeezed downward, it can be delivered to the inside of the telescopic member 4310 through the air inlet hole 438. When the telescopic member 4310 receives the gas, it will extend. When the telescopic member 4310 extends, it can push the moving block 4311 to move.
