Description

Technical Field

[0001] This utility model relates to the field of packaging bag coding technology, and in particular to a coding device for composite packaging bags. Background Technology

[0002] The composite packaging bag processing coding device is an automated identification information printing device installed before or after the bag making, sealing, or forming process of composite packaging bags, or in the packaging production line. It is widely used in the flexible packaging industry such as food, pharmaceuticals, daily chemicals, and chemicals. The core function of this device is to achieve accurate, clear, and variable content printing on the surface of the packaging bag through non-contact coding technology (such as thermal foaming, continuous inkjet printing, or laser coding) at high speed. The content may include key information such as production date, batch number, barcode, QR code, product identification, and regulatory code.

[0003] Existing inkjet printing devices for composite packaging bags mostly use a self-rotating structure of the inkjet head to adjust the printing angle. However, their rotation structure is mostly single-axis or fixed-angle displacement, which cannot quickly switch between horizontal and vertical inkjet printing. The adjustment process is cumbersome, the positioning accuracy is poor, it is not conducive to continuous operation, and it reduces the efficiency of the equipment in adapting to different packaging needs.

[0004] Therefore, in view of the problems that existing composite packaging bag processing inkjet printing devices usually adjust the printing angle through the self-rotating structure of the inkjet head, but most of them are single-axis or fixed-angle rotation, making it difficult to achieve rapid switching between horizontal and vertical inkjet printing, complex adjustment operation, inaccurate positioning, affecting continuous operation efficiency and the equipment's adaptability to different packaging specifications, there is an urgent need to design a new type of composite packaging bag processing inkjet printing device. Utility Model Content

[0005] To overcome the problems of existing composite packaging bag processing inkjet printing devices, which usually adjust the printing angle through the self-rotating structure of the inkjet head, but are mostly single-axis or fixed-angle rotations, it is difficult to achieve rapid switching between horizontal and vertical inkjet printing, the adjustment operation is complicated, the positioning is inaccurate, and the continuous operation efficiency and the equipment's adaptability to different packaging specifications are affected.

[0006] The technical solution of this utility model is as follows: a composite packaging bag processing coding device, comprising a connecting plate and an upper irregularly shaped block installed at the bottom of the connecting plate. The bottom of the upper irregularly shaped block is wavy. A support column is connected to the top of the connecting plate. A top plate is connected to the end of the support column away from the connecting plate. A spring is connected to the bottom of the top plate. Connecting columns are connected to the front and rear sides of the bottom of the connecting plate. A lower irregularly shaped block is connected between the two connecting columns. The top of the lower irregularly shaped block is wavy. The lower irregularly shaped block cooperates with the upper irregularly shaped block. A lifting column is movably connected to the bottom of the spring. A limit plate is connected to the end of the connecting column away from the connecting plate. The outer end of the lifting column is connected to a limit rod, which is movably connected to the lower and upper irregular blocks. The outer end of the lifting column has a circular groove, through which the lifting column is slidably connected to the limit plate. The lifting column passes through the limit plate and is connected to an inkjet printer. Auxiliary blocks are connected to both sides of the inkjet printer. The bottom of the auxiliary blocks is rotatably connected to a ball bearing. When the inkjet printer contacts the ground, it drives the auxiliary blocks to compress the spring of the lifting column. The lifting column rises and causes the limit rod to collide with the lower irregular block. The wave-like shape at the bottom of the lower irregular block causes the limit rod to rotate the lifting column. The spring drives the lifting column to reset and the limit rod is locked onto the lower irregular block.

[0007] Preferably, by setting up upper and lower irregular blocks, when the horizontal and vertical direction of the inkjet printer needs to be adjusted, the lifting mechanism is activated to lower the connecting plate, the ball bearings contact the ground and roll, thereby driving the auxiliary block to move. The auxiliary block further pushes the lifting column down, compressing the spring, so that the limit rod abuts against the bottom of the upper irregular block. Utilizing the guiding effect of the wave-shaped structure at the bottom of the upper irregular block, the limit rod drives the lifting column to rotate smoothly, thereby driving the inkjet printer to complete the direction switch. Subsequently, the connecting plate is raised, and the lifting column moves down under the action of the spring. The limit rod is embedded in the limiting groove of the lower irregular block to achieve stable locking, completing the direction conversion of the inkjet printer. This enables the inkjet printer to quickly switch between horizontal and vertical directions without cumbersome adjustments during operation, significantly improving the equipment's adaptability to different packaging bag sizes and the continuity of operation.

[0008] Preferably, the rear end of the connecting plate is connected to a lifting block, and the outer end of the lifting block is slidably connected to a lifting frame.

[0009] Preferably, the lifting block is internally connected to a screw, and the top of the lifting frame is connected to a motor, the output end of which is connected to the screw.

[0010] Preferably, the rear end of the lifting frame is connected to a mounting plate, and the mounting plate has mounting holes on the left and right sides inside, which are connected to external screws.

[0011] Preferably, the front end of the inkjet printer is connected to a fixing block, and the left and right sides inside the fixing block are connected to infrared sensing modules. The infrared sensing modules are electrically connected to an external controller, and the inkjet printer is electrically connected to the external controller.

[0012] Preferably, the front end of the inkjet printer is connected to an ink tank, and the top of the ink tank is provided with an ink filling port.

[0013] Preferably, ink is injected into the ink filling port and stored in the ink tank, which is used to supply ink to the inkjet printer. The infrared sensing module is used to sense objects and start the inkjet printer through an external controller.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using the guide of irregularly shaped blocks and the positioning function of the limiting rod, the inkjet printer can quickly switch between horizontal and vertical directions. The entire switching process requires no complicated operations, the conversion is smooth and stable, the structure is reasonably designed, and the operation is reliable. It not only significantly shortens the time for adjusting the inkjet direction, but also effectively ensures the stability and positional consistency during the switching process. This device is suitable for the processing needs of composite packaging bags with different sizes and layout requirements, which helps to improve the cycle time efficiency and switching efficiency of the entire line. It is especially suitable for automated processing and production scenarios with diverse packaging categories and frequent batch changes, which increases production capacity while reducing the need for human intervention.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a composite packaging bag processing coding device, including a connecting plate 1 and an upper irregular block 21 installed at the bottom of the connecting plate 1. The bottom of the upper irregular block 21 is wavy. A support column 22 is connected to the top of the connecting plate 1. A top plate 23 is connected to the end of the support column 22 away from the connecting plate 1. A spring 24 is connected to the bottom of the top plate 23. Connecting columns 25 are connected to the front and rear sides of the bottom of the connecting plate 1. A lower irregular block 26 is connected between the two connecting columns 25. The top of the lower irregular block 26 is wavy. The lower irregular block 26 cooperates with the upper irregular block 21. The spring 24... A lifting column 27 is movably connected to the bottom. A limiting plate 29 is connected to the end of the connecting column 25 away from the connecting plate 1. A limiting rod 28 is connected to the outer end of the lifting column 27. The limiting rod 28 is movably connected to the lower irregular block 26 and the upper irregular block 21. A circular groove is provided on the outer end of the lifting column 27, and the lifting column 27 is slidably connected to the limiting plate 29 through the circular groove. A coding device 210 is connected to the lifting column 27 through the limiting plate 29. Auxiliary blocks 211 are connected to both sides of the coding device 210. A ball bearing 212 is rotatably connected to the bottom of the auxiliary block 211. When the coding device 210 contacts the ground, it drives the auxiliary block 211 to lift. The column 27 compresses the spring 24, causing the lifting column 27 to rise and collide with the limit rod 28 and the lower irregular block 26. The wave-like shape at the bottom of the lower irregular block 26 causes the limit rod 28 to rotate, and the spring 24 causes the lifting column 27 to reset, locking the limit rod 28 into the lower irregular block 26. By setting the upper irregular block 21 and the lower irregular block 26, when the horizontal and vertical directions of the inkjet printer 210 need to be adjusted, the lifting mechanism is activated, causing the connecting plate 1 to descend. The ball bearing 212 contacts the ground and rolls, thereby driving the auxiliary block 211 to move. The auxiliary block 211 further pushes the lifting column 27 downward, compressing the spring 24, causing... The limiting rod 28 abuts against the bottom of the upper irregular block 21. Utilizing the guiding effect of the wave-shaped structure at the bottom of the upper irregular block 21, the limiting rod 28 drives the lifting column 27 to rotate smoothly, thereby driving the inkjet printer 210 to complete the direction switch. Subsequently, the connecting plate 1 is raised, and the lifting column 27 moves down under the action of the spring 24. The limiting rod 28 is embedded in the limiting groove of the lower irregular block 26 to achieve stable locking, completing the direction conversion of the inkjet printer 210. This enables the inkjet printer 210 to switch quickly between horizontal and vertical directions. The operation process does not require cumbersome adjustments, significantly improving the equipment's adaptability to packaging bags of different specifications and the continuity of operation.

[0024] Please see Figures 1-5In this embodiment, a lifting block 31 is connected to the rear end of the connecting plate 1, and a lifting frame 32 is slidably connected to the outer end of the lifting block 31. A screw 33 is rotatably connected inside the lifting block 31, and a motor 34 is connected to the top of the lifting frame 32. The output end of the motor 34 is connected to the screw 33. A mounting plate 35 is connected to the rear end of the lifting frame 32. Mounting holes 36 are provided on the left and right sides inside the mounting plate 35. The mounting holes 36 are connected to external screws. The motor 34 drives the screw 33 to rotate, thereby realizing the up and down adjustment of the lifting block 31 inside the lifting frame 32. This drives the connecting plate 1 to move vertically as a whole, which helps to assist the inkjet printer 210 to rotate. It can also increase the height of the inkjet printer 210 according to the inkjet printing requirements of different packaging bags, thereby improving the adaptability and adjustment flexibility of the equipment.

[0025] Please see Figures 2-5 In this embodiment, a fixing block 37 is connected to the front end of the inkjet printer 210. Infrared sensing modules 38 are connected to the left and right sides inside the fixing block 37. The infrared sensing modules 38 are electrically connected to an external controller. The inkjet printer 210 is also electrically connected to the external controller. An ink tank 39 is connected to the front end of the inkjet printer 210. An ink inlet 310 is provided on the top of the ink tank 39. Ink is injected into the ink inlet 310 and stored in the ink tank 39. The ink tank 39 is used to provide ink to the inkjet printer 210. The infrared sensing module 38 is used to sense objects and start the inkjet printer 210 through the external controller. The infrared sensing module 38, model Si1143, works in conjunction with the external controller to achieve automatic identification of the object to be printed. The infrared sensing module 38 responds to the start of the inkjet printer 210, improving the automation level and response speed of the printing process. The ink tank 39 works in conjunction with the inkjet printer 210 to ensure a continuous and stable ink supply, supporting long-term uninterrupted printing operations, further improving printing efficiency and device stability.

[0026] When the coding direction of the inkjet printer 210 needs to be adjusted during operation, the lifting mechanism is first activated. The motor 34 drives the screw 33 to rotate, which in turn drives the lifting block 31 to slide along the lifting frame 32, causing the connecting plate 1 to move down as a whole. During the descent of the connecting plate 1, the ball bearing 212 at the bottom of the inkjet printer 210 first contacts the ground and begins to roll. The rolling motion drives the auxiliary block 211 to move horizontally. The auxiliary block 211 further pushes the lifting column 27 upward, squeezing the spring 24 below the top plate 23, so that the limiting rod 28 contacts the bottom of the upper irregular block 21. Since the bottom of the upper irregular block 21 adopts a wave-shaped structure, the limiting rod 28 drives the lifting column 27 to rotate under its guiding action. The rotation of the lifting column 27 causes the inkjet printer 210 to complete the angle switching accordingly. After the inkjet printer 210 is oriented, the motor 34 reverses direction, the connecting plate 1 rises, and under the action of the spring 24, the lifting column 27 moves downward. The limiting rod 28 is embedded in the wave-shaped limiting groove of the lower irregular block 26, achieving stable directional locking of the inkjet printer 210. This structure allows for quick and reliable switching between horizontal and vertical inkjet printing without complicated operations, significantly improving the equipment's adaptability to multi-specification composite packaging bags and operational continuity. During inkjet printing, the infrared sensing module 38 at the front end of the inkjet printer 210 can sense the position and status of the object to be printed in real time and transmit the signal to the external controller. The controller then controls the inkjet printer 210 to start as needed, ensuring the accuracy and timeliness of the inkjet printing. Simultaneously, the ink tank 39 continuously provides a stable ink source to the inkjet printer 210 after ink is injected through the ink filling port 310, ensuring the continuity and efficiency of the inkjet printing operation and meeting the requirements of high-cycle automated production lines.

[0027] Through the above steps, the inkjet printer 210 can quickly switch between horizontal and vertical modes by guiding the contour of the irregular block and cooperating with the limiting rod 28. The entire switching process requires no complex adjustments, the operation is smooth and the positioning is stable, which can significantly shorten the adjustment time and ensure the consistency and smoothness of the switching process. This design can flexibly adapt to the inkjet printing needs of composite packaging bags of different sizes and formats, effectively improve the switching response speed and working rhythm of the entire production line, and is particularly suitable for automated packaging production lines with multiple types and frequent product changes. While improving capacity and efficiency, it also significantly reduces manual intervention and improves practicality. This solves the problem that existing composite packaging bag processing inkjet printing devices usually adjust the printing angle through the self-rotating structure of the inkjet head, but most of them are single-axis or fixed-angle rotation, which makes it difficult to achieve rapid switching between horizontal and vertical inkjet printing, and the adjustment operation is complicated, the positioning is inaccurate, and it affects the efficiency of continuous operation and the equipment's adaptability to different packaging specifications.
