Description

Technical Field

[0001] This utility model relates to the field of automatic coding technology, and in particular to an automatic coding machine for feed packaging bags. Background Technology

[0002] The automatic coding machine for feed packaging bags is designed specifically for the feed industry. It is an automated device that can automatically print key information on the surface of feed packaging bags. It is used in conjunction with feed packaging production lines. It can accurately print production date, shelf life, batch number, product specifications, and manufacturer information. Its core advantage is that it replaces manual coding, improves efficiency, and ensures that the information is clear, the position is consistent, and errors are reduced. It helps feed companies meet food safety traceability requirements and comply with industry quality control standards.

[0003] The automatic coding machine for feed packaging bags has significant advantages. It can effectively replace manual coding, adapt to the high-speed rhythm of feed packaging production lines, and can process dozens to hundreds of packaging bags per minute.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model is provided: an automatic coding machine for feed packaging bags, including a conveyor belt frame 1, a coding machine fixing frame 2 is provided on the rear side of the conveyor belt frame 1, a coding pre-pressing mechanism 3 is provided on the top right side of the conveyor belt frame 1, the coding pre-pressing mechanism 3 is used to press the packaging bag flat before coding, a coding mechanism 4 is provided on the top of the coding machine fixing frame 2, the coding mechanism 4 is used to code various feed packaging bags of different sizes, and a conveying mechanism 5 is provided inside the conveyor belt frame 1; The pre-pressing mechanism 3 for coding includes two telescopic limiting posts 31. The bottom of the two telescopic limiting posts 31 is fixedly connected to the front and rear sides of the top of the conveyor belt frame 1, respectively. The top of each of the two telescopic limiting posts 31 is fixedly connected to a lifting plate 32. The same cover 33 is fixedly connected between adjacent lifting plates 32. Multiple pressure rollers 34 are rotatably connected inside the cover 33. Multiple height adjustment components 35 are provided on the front and rear sides of the cover 33. Specifically, after the equipment is started, the feed packaging bags to be coded are conveyed to the conveyor mechanism 5 of the conveyor belt frame 1. The conveyor mechanism 5 operates and drives the feed packaging bags to move along a set direction, realizing automatic conveying of the packaging bags. When the feed packaging bags move to below the pre-coding flattening mechanism 3, the pre-coding flattening mechanism 3 begins to flatten the packaging bags. The two telescopic limit posts 31 in the pre-coding flattening mechanism 3 are fixed to the front and rear sides of the top of the conveyor belt frame 1, respectively, providing stable support for the entire flattening mechanism; the top of the two telescopic limit posts 31 is fixed to... The lifting plate 32 securely supports the machine cover 33 above the conveying mechanism 5. When the feed packaging bag passes under the machine cover 33, multiple pressure rollers 34 rotatably connected inside the machine cover 33 and the conveying mechanism 5 roll and flatten the surface of the packaging bag. At the same time, multiple height adjustment components 35 set on the front and rear sides of the machine cover 33 can adjust the distance between the pressure rollers 34 and the conveying mechanism 5 according to the thickness of the packaging bag. Through the rolling flattening of the pressure rollers 34 and the adjustment of the distance between the height adjustment components 35, the packaging bags of different thicknesses can be effectively flattened to ensure that the surface of the packaging bag is flat and wrinkle-free. After being flattened by the pre-printing flattening mechanism 3, the feed packaging bag is moved under the continuous conveying of the conveyor mechanism 5 to the bottom of the printing mechanism 4 set at the top of the printing machine mounting frame 2. The printing machine mounting frame 2 provides stable installation support for the printing mechanism 4, keeping the printing mechanism 4 in the set printing position. The printing mechanism 4 performs printing operation on the flat feed packaging bag passing below it according to the preset printing information. Since the packaging bag has been flattened by the pre-printing flattening mechanism 3, the printing mechanism 4 can accurately form clear printing marks on the surface of the packaging bag. After printing, the feed packaging bag continues to move under the drive of the conveyor mechanism 5 and is finally conveyed out from the output end of the conveyor belt frame 1, completing the entire automatic printing process.

[0020] Reference Figure 4 The coding mechanism 4 includes an ink tank 41. The right side of the ink tank 41 is fixedly connected to the left side of the inner wall of the coding machine mounting frame 2. The left side of the ink tank 41 is connected to a connecting pipe 42. The bottom end of the connecting pipe 42 is connected to an inkjet gun 43. The top of the coding machine mounting frame 2 is fixedly connected to a control console 44. The bottom end of the coding machine mounting frame 2 is fixedly connected to multiple rollers 45. The inside of the coding machine mounting frame 2 is provided with two sliding components 46. The left side of the inkjet gun 43 is provided with a pressing component 47. Specifically, when the feed packaging bag flattened by the pre-printing flattening mechanism 3 moves to the bottom of the inkjet printer mounting frame 2 under the drive of the conveying mechanism 5, the inkjet printer mechanism 4 starts to operate. The ink tank 41 of the inkjet printer mechanism 4 is fixedly connected to the left side of the inner wall of the inkjet printer mounting frame 2 on the right side. The ink tank 41 provides ink reserves for printing. The connecting pipe 42 connected to the left side of the ink tank 41 transports the ink in the ink tank 41 to the inkjet gun 43 connected to the bottom end of the connecting pipe 42. Through the ink reserves of the ink tank 41 and the ink transport of the connecting pipe 42, the effect of supplying printing ink to the inkjet gun 43 is achieved. The control console 44 fixedly connected to the top of the inkjet printer mounting frame 2 can preset the printing information and control the operation of the inkjet printer mechanism 4. After the operator sets the parameters through the control console 44, the control console 44 sends the printing command to the inkjet gun 43. The inkjet gun 43 prints ink on the flat packaging bag passing below according to the command. Two sliding components 46 inside the inkjet printer mounting bracket 2 are linked to the inkjet gun 43. When the coding position of the inkjet gun 43 needs to be adjusted to adapt to feed packaging bags of different sizes, the sliding components 46 drive the inkjet gun 43 to move along the set direction, adjusting the horizontal position of the inkjet gun 43. At the same time, the pressing component 47 on the left side of the inkjet gun 43 can push the inkjet gun 43 to move vertically, adjusting the distance between the inkjet gun 43 and the surface of the packaging bag. By adjusting the horizontal position of the sliding components 46 and the vertical distance of the pressing components 47, the coding position and height of the inkjet gun 43 can be flexibly adjusted to ensure that it can adapt to various feed packaging bags of different sizes. Multiple rollers 45 fixedly connected to the bottom of the inkjet printer mounting bracket 2 can drive the inkjet printer mounting bracket 2 and the coding mechanism 4 installed on it to move as a whole, which facilitates the adjustment of the overall position of the coding mechanism 4 according to the production line layout. Through the rolling of the rollers 45 and the overall support of the inkjet printer mounting bracket 2, the coding mechanism 4 can be flexibly arranged in the production line.

[0021] Reference Figures 2-4 The height adjustment assembly 35 includes multiple upper fixed plates 353, with adjacent sides of each upper fixed plate 353 fixedly connected to the front and rear sides of the cover 33. Each upper fixed plate 353 has a threaded post 352 fixedly connected to its bottom end. Multiple lower fixed plates 351 are fixedly connected to the front and rear sides of the conveyor belt frame 1, with the threaded posts 352 threadedly connected to the interior of the lower fixed plates 351. The sliding assembly 46 includes two slides 461 arranged in a cross-shaped layout. The interior of each slide 461... A slide bar 462 is fixedly connected, and a slider 463 is slidably connected inside both slide bars 462. The rear side of the longitudinal slide table 461 is fixedly connected to the front side of the transverse slider 463. The pressing assembly 47 includes a fixed platform 471. The left side of the fixed platform 471 is fixedly connected to the right side of the longitudinal slider 463. A cylinder 472 is fixedly connected to the top of the interior of the fixed platform 471. An inkjet mounting bracket 473 is fixedly connected to the output end of the cylinder 472. An inkjet gun 43 is fixedly connected inside the inkjet mounting bracket 473. Specifically, multiple upper fixing plates 353 of the height adjustment component 35 are fixedly connected to the front and rear sides of the cover 33 on adjacent sides. The threaded post 352 fixed at the bottom of the upper fixing plate 353 is threadedly connected to the interior of multiple lower fixing plates 351 fixed on the front and rear sides of the conveyor frame 1. The operator rotates the threaded post 352 to drive the upper fixing plate 353 and the cover 33 to move up and down, thereby adjusting the distance between the pressure roller 34 inside the cover 33 and the conveying mechanism 5. Through the threaded transmission of the threaded post 352 and the fixed support of the lower fixing plate 351, the height of the pressure roller 34 can be flexibly adjusted according to the thickness of the packaging bag, ensuring that the pressure roller 34 can effectively flatten packaging bags of different thicknesses. During the operation of the coding mechanism 4, the sliding component 46 and the pressing component 47 adjust the position of the inkjet gun 43. The two slides 461 of the sliding component 46 are arranged in a cross pattern. A slider 463 is slidably connected to a slide rod 462 fixed inside the slide 461. The rear side of the longitudinal slide 461 is fixedly connected to the front side of the transverse slider 463. When the transverse slider 463 slides along the transverse slide rod 462, it drives the longitudinal slide 461 to move laterally in sync. When the longitudinal slider 463 slides along the longitudinal slide rod 462, the position can be adjusted in the longitudinal direction. The sliding mechanism enables multi-directional position adjustment of the inkjet gun 43 within the plane. The left side of the fixed platform 471 of the pressing component 47 is fixedly connected to the right side of the longitudinal slider 463. The output end of the cylinder 472 fixed at the top inside the fixed platform 471 is fixedly connected to the inkjet mounting bracket 473. The inkjet gun 43 fixed inside the inkjet mounting bracket 473 moves synchronously with the inkjet mounting bracket 473. When the cylinder 472 extends or retracts, it pushes the inkjet mounting bracket 473 and the inkjet gun 43 to move up and down. Through the extension and retraction drive of the cylinder 472 and the fixed support of the inkjet mounting bracket 473, the height adjustment of the inkjet gun 43 in the vertical direction is achieved.

[0022] Reference Figure 5 The conveying mechanism 5 includes a pallet 51, the front side of which is fixedly connected to the rear side of the conveyor belt frame 1. An operation panel 52 is fixedly connected to the front side of the pallet 51. Multiple support legs 53 are fixedly connected to the bottom of the conveyor belt frame 1. A transmission assembly 55 is provided on the top of the pallet 51. Multiple rollers 54 are rotatably connected to the top of the inner part of the conveyor belt frame 1. The multiple rollers 54 are made of stainless steel and have multiple anti-slip grooves on their outer walls. The transmission assembly 55 includes a second motor 551, the bottom of which is fixedly connected to the top of the pallet 51. A chain 552 is meshed with the output end of the pallet 51. Two gears 553 are fixedly connected to the rear side of each of the multiple rollers 54. A transmission chain 554 is meshed with the outer wall of each of the multiple gears 553. Specifically, the front side of the pallet 51 of the conveyor mechanism 5 is fixedly connected to the rear side of the conveyor belt frame 1. The pallet 51 provides mounting support for the operation panel 52 and the transmission component 55. The operation panel 52 fixedly connected to the front side of the pallet 51 can control the start and stop of the transmission component 55. The operator can adjust the operating status of the conveyor mechanism 5 by sending commands through the operation panel 52. Multiple support legs 53 fixedly connected to the bottom of the conveyor belt frame 1 provide support for the conveyor belt frame 1 and the entire conveyor mechanism 5. Through the support of the support legs 53 and the bearing of the pallet 51, the conveyor mechanism 5 is stably placed during the operation. The transmission assembly 55 at the top of the pallet 51 provides power for the rotation of the rollers 54. The motor 551 of the transmission assembly 55 is fixedly connected to the top of the pallet 51 at its bottom. After the motor 551 is started, its output end drives the meshing chain 552 to rotate. The chain 552 transmits power to the gear 553 associated with it. Two gears 553 are fixedly connected to the rear side of each roller 54, and the outer walls of each gear 553 are meshed with a transmission chain 554. When one of the gears 553 rotates under the drive of the chain 552, the meshing transmission of the transmission chain 554 drives all the gears 553 to rotate synchronously, thereby causing the multiple rollers 54 rotatably connected to the top of the conveyor belt frame 1 to rotate synchronously. The synchronous rotation of the multiple rollers 54 is achieved through the power output of the motor 551 and the transmission of the chain 552, gears 553, and transmission chain 554, providing power for the conveying of packaging bags. The feed packaging bags to be coded are placed on multiple rollers 54. When the rollers 54 rotate, they drive the packaging bags to move in a set direction. Since the multiple rollers 54 are made of stainless steel and have multiple anti-slip grooves on their outer walls, the packaging bags can be prevented from slipping during the conveying process. Through the rotation of the rollers 54 and the anti-slip effect of the anti-slip grooves, the feed packaging bags can be moved smoothly.

[0023] Working principle: Before starting the equipment, the operator can make preliminary adjustments according to the specifications of the feed packaging bags to be coded. For the pre-coding flattening mechanism 3, the multiple upper fixing plates 353 of its height adjustment component 35 are fixedly connected to the front and rear sides of the cover 33 on adjacent sides. The threaded post 352 fixed at the bottom of the upper fixing plate 353 is threadedly connected to the interior of the multiple lower fixing plates 351 fixed on the front and rear sides of the conveyor frame 1. By rotating the threaded post 352, the operator drives the upper fixing plate 353 and the cover 33 to move up and down, thereby adjusting the distance between the pressure roller 34 inside the cover 33 and the roller 54 in the conveyor mechanism 5. The lower fixing plate 351 is connected to the lower fixing plate 351 through the threaded transmission of the threaded post 352. The fixed support of 51 allows for flexible adjustment of the height of the pressure roller 34 according to the thickness of the packaging bag, ensuring that subsequent flattening operations are adapted to the current packaging bag size. For the coding mechanism 4, the operator presets coding information via the control console 44 fixedly connected to the top of the coding machine mounting bracket 2, and simultaneously adjusts the position of the inkjet gun 43 according to the size of the packaging bag. Two sliding components 46 inside the coding machine mounting bracket 2 are linked to the inkjet gun 43. The two slides 461 of the sliding components 46 adopt a cross-shaped layout. A slider 463 is slidably connected to a slide rod 462 fixed inside the slide 461. The rear side of the longitudinal slide 461 is fixedly connected to the front side of the transverse slider 463. When block 463 slides along the transverse slide bar 462, it drives the longitudinal slide table 461 to move laterally in sync. When the longitudinal slider 463 slides along the longitudinal slide bar 462, it achieves position adjustment in the longitudinal direction. By sliding the transverse slider 463 and the longitudinal slider 463, the position of the inkjet gun 43 in the plane is adjusted. The left side of the fixing platform 471 of the pressing assembly 47 is fixedly connected to the right side of the longitudinal slider 463. The output end of the cylinder 472 fixed at the top of the fixing platform 471 is fixedly connected to the inkjet mounting bracket 473. The inkjet gun 43 fixed inside the inkjet mounting bracket 473 moves synchronously with the inkjet mounting bracket 473. When the cylinder 472 extends or retracts, it pushes the inkjet mounting bracket 473 and... The inkjet gun 43 moves up and down, and through the extension and retraction drive of the cylinder 472 and the fixed support of the inkjet mounting frame 473, the vertical distance between the inkjet gun 43 and the roller 54 in the conveying mechanism 5 is adjusted, so that the inkjet gun 43 is in the coding position that is suitable for the current packaging bag. If it is necessary to adjust the overall position of the coding mechanism 4 according to the production line layout, multiple rollers 45 fixedly connected to the bottom of the coding machine mounting frame 2 can be used to push the coding machine mounting frame 2 and the coding mechanism 4 installed on it to move as a whole. Through the rolling drive of the rollers 45 and the overall support of the coding machine mounting frame 2, the coding mechanism 4 can be flexibly arranged in the production line. After the initial adjustment is completed, the equipment enters the standby state. After the equipment is officially started, the operator places the feed packaging bags to be coded on the multiple rollers 54 of the conveyor mechanism 5. Then, the operator sends a start command through the operation panel 52 fixedly connected to the front of the pallet 51 to control the operation of the transmission component 55. The front of the pallet 51 of the conveyor mechanism 5 is fixedly connected to the rear of the conveyor belt frame 1, providing mounting support for the operation panel 52 and the transmission component 55. Multiple support legs 53 fixedly connected to the bottom of the conveyor belt frame 1 provide support for the conveyor belt frame 1 and the entire conveyor mechanism 5. Through the support of the support legs 53 and the load-bearing capacity of the pallet 51, the stable placement of the conveyor mechanism 5 is ensured during operation. The bottom of the motor 551 of the transmission component 55 is fixedly connected to the top of the pallet 51. After the motor 551 is started, its output end drives the meshing chain 552 to rotate. The chain 552 transmits power to the associated gear 553, and the multiple rollers 54 are then... Each side is fixedly connected to two gears 553, and the outer walls of multiple gears 553 are meshed with transmission chains 554. When one of the gears 553 rotates under the drive of the chain 552, the meshing transmission of the transmission chain 554 drives all gears 553 to rotate synchronously, thereby causing multiple rollers 54 rotatably connected to the top of the conveyor belt frame 1 to rotate synchronously. The synchronous rotation of multiple rollers 54 is achieved through the power output of motor 2 551 and the transmission of the chain 552, gears 553, and transmission chain 554, providing power for the conveying of packaging bags. When the rollers 54 rotate, they drive the feed packaging bags on them to move in a set direction. Since multiple rollers 54 are made of stainless steel and have multiple anti-slip grooves on their outer walls, the packaging bags can be prevented from slipping during the conveying process. Through the rotation of the rollers 54 and the anti-slip effect of the anti-slip grooves, the feed packaging bags can be moved smoothly, completing the automatic conveying of the packaging bags. When the feed packaging bag moves under the roller 54 to the bottom of the pre-printing flattening mechanism 3, the pre-printing flattening mechanism 3 begins to flatten the packaging bag. The two telescopic limit posts 31 in the pre-printing flattening mechanism 3 are fixed to the front and rear sides of the top of the conveyor frame 1, respectively, to provide stable support for the entire flattening mechanism. The lifting plate 32 fixed to the top of the two telescopic limit posts 31 firmly supports the cover 33 above the conveyor mechanism 5. When the feed packaging bag passes under the cover 33, the multiple pressure rollers 34 rotatably connected inside the cover 33 and the rollers 54 of the conveyor mechanism 5 roll and flatten the surface of the packaging bag. The previously adjusted height adjustment component 35 has ensured that the distance between the pressure rollers 34 and the rollers 54 is adapted to the current packaging bag thickness. Through the rolling flattening of the pressure rollers 34 and the distance adjustment of the height adjustment component 35, the packaging bag of the current thickness is effectively flattened, ensuring that the surface of the packaging bag is flat and wrinkle-free, providing a flat coding surface for subsequent printing operations. After being flattened by the pre-printing flattening mechanism 3, the feed packaging bag continues to move under the continuous conveying of the rollers 54 of the conveying mechanism 5 to the bottom of the printing mechanism 4 set at the top of the printing machine mounting frame 2. The printing machine mounting frame 2 provides stable installation support for the printing mechanism 4, keeping it in the set printing position. The ink tank 41 of the printing mechanism 4 is fixedly connected to the left side of the inner wall of the printing machine mounting frame 2 on the right side. The ink tank 41 provides ink for printing, and the connecting pipe 42 connected to the left side of the ink tank 41 delivers the ink in the ink tank 41. The inkjet gun 43, which is connected to the bottom of the connecting tube 42, is supplied with coding ink through the ink storage in the ink tank 41 and the ink delivery through the connecting tube 42. The control console 44 sends coding instructions to the inkjet gun 43 according to the preset coding information. The inkjet gun 43 performs inkjet coding on the flat packaging bag passing below according to the instructions. Since the packaging bag has been flattened by the pre-coding flattening mechanism 3, the inkjet gun 43 can accurately form clear coding marks on the surface of the packaging bag, thus completing the coding operation of the feed packaging bag. After coding, the feed packaging bags continue to move along the set direction under the continuous drive of the rollers 54 of the conveyor mechanism 5, and are finally conveyed out from the output end of the conveyor frame 1. Thus, the automatic coding machine for feed packaging bags completes a complete automatic coding process. In the future, continuous automatic coding operations can be achieved by continuously feeding materials into the conveyor mechanism 5.
