Description

Technical Field

[0001] This utility model relates to the field of packaging box coding technology, specifically a packaging box coding device. Background Technology

[0002] Packaging boxes are containers used to package goods. After packaging is completed, the boxes are usually marked with inkjet printing.

[0003] A Chinese patent with announcement number CN211942304U discloses an automatic inkjet coding device for cartons, including a horizontal plate, a motor, and a mounting plate. Vertical plates are symmetrically arranged on both sides of the horizontal plate, and a support plate is fixedly connected to the top of each vertical plate. A connecting plate is fixedly connected between the support plates, and a sliding plate is provided on the top of the connecting plate. A screw is threadedly connected inside the sliding plate. One end of the screw passes through the support plate and connects to the output end of the motor, while the other end of the screw is connected to a bearing on the support plate. A sliding groove is formed in the middle of the connecting plate, and a slider is slidably connected within the sliding groove. This invention has a simple structure and reasonable design. When a carton conveyed at the top of the conveyor belt passes the sensor, the sensor detects the carton and the controller controls the inkjet printer to print codes on the carton, improving work efficiency.

[0004] The aforementioned automatic inkjet printing device for cartons is inconvenient to limit the movement of cartons during transport, causing them to shift and potentially resulting in skewed printing, which affects the quality and accuracy of the printing. Furthermore, existing automatic inkjet printing devices for cartons lack an effective drying mechanism, allowing the ink to flow or spread before it dries, leading to blurred and unclear characters, thus affecting the clarity and readability of the printed content. Therefore, a new packaging box inkjet printing device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a packaging box coding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A packaging box coding device of this utility model includes two support plates. Two conveyor rollers are installed between the two support plates via a rotating shaft, and the two conveyor rollers are located at opposite ends of the support plates. A conveyor belt is fitted onto the outer surface of the two conveyor rollers. A first motor is installed on one of the support plates, and the output end of the first motor is connected to one end of one of the rotating shafts. Fixing blocks are installed on both support plates, and first pneumatic cylinders are installed on both fixing blocks. First pneumatic rods are fitted to the working ends of both first pneumatic cylinders, and L-shaped fixing frames are fixedly connected to the ends of both first pneumatic rods. Multiple limiting wheels are rotatably installed within each L-shaped fixing frame. Two limiting wheels are fixedly connected to the top side of each support plate. The device includes a fixed base, each with a rod hole through which a limit rod is inserted. One end of each limit rod is fixed to an L-shaped fixing frame. The two limit rods are located on either side of the first pneumatic cylinder. To prevent the packaging box from shifting during transport, a limiting mechanism is used. When the packaging box is placed on the conveyor belt, the first pneumatic cylinder is activated, causing the first pneumatic rod to move the L-shaped fixing frame and the limit wheels. This causes the limit wheels on both sides to move closer together until they contact the side walls of the packaging box. At this point, the first pneumatic cylinder stops operating, effectively limiting the packaging box. Under the action of the limit wheels, the packaging box moves stably on the conveyor belt, preventing it from shifting during transport and ensuring the quality and accuracy of the coding.

[0007] Preferably, a support plate is fixed between the two support plates, and the support plate is set inside the conveyor belt. When using the device, the support plate provides additional support for the conveyor belt, preventing it from sagging or deforming during operation, thereby ensuring the smooth operation of the conveyor belt.

[0008] Preferably, each of the two support plates is equipped with a second pneumatic cylinder, and the working end of each of the two second pneumatic cylinders is fitted with a second pneumatic rod. A fixed plate is fixedly connected to the top of each of the two second pneumatic rods. A second motor is mounted on one of the fixed plates, and the output end of the second motor is connected to a lead screw. The other end of the lead screw is rotatably mounted on the other fixed plate. A movable block is sleeved on the lead screw, and an inkjet printer is mounted on the bottom side of the movable block. Two guide rods are fixedly connected between the two fixed plates, and the two guide rods are located on opposite sides of the lead screw. A limiting block is sleeved on each of the two guide rods, and the limiting block is fixedly connected to the movable block. When inkjet printing on the packaging box, the operation of the second pneumatic cylinder causes the second pneumatic rod to move the fixed plate and the inkjet printer up or down, thereby adjusting the height of the inkjet printer. This facilitates inkjet printing on packaging boxes of different heights. The operation of the second motor causes the lead screw to rotate, and with the cooperation of the guide rods and the limiting block, the movable block drives the inkjet printer to move stably, thus facilitating inkjet printing on different positions of the packaging box as needed.

[0009] Preferably, two support plates are fixedly connected to a support frame. Each side of the support frame has a sliding groove, and each sliding groove contains a lifting plate. An air diffuser is fixed between the two lifting plates. Two third motors are installed on the top side of the support frame. The output end of each third motor is connected to a threaded rod, which is located within the sliding groove and passes through the lifting plate. During the drying process, the third motors rotate, forcing the lifting plate to move up or down along the sliding groove. This causes the air diffuser to move up or down accordingly, allowing the position of the air diffuser to be adjusted according to the height of the packaging box, facilitating better drying of the ink after coding.

[0010] Preferably, a heating box is fixed to the top side of the support frame, a heating tube is installed inside the heating box, and a gas supply hose is connected between the heating box and the air diffuser. A fourth motor is installed on the top side of the heating box, and a fan is installed at the output end of the fourth motor. An air inlet pipe is connected to the top side of the heating box. After the packaging box is printed, in order to dry the printed ink quickly, a drying mechanism is set up, the fourth motor is started, and the fan rotates. With the cooperation of the heating tube, the heated high-temperature gas can be blown into the air diffuser through the gas supply hose. The air diffuser increases the contact area between the hot air and the surface of the packaging box, thereby enabling the printed ink to dry quickly and adhere firmly to the surface of the packaging box. This not only prevents the ink from flowing or spreading on the packaging box, causing the text to become blurred or deformed, but also ensures the clarity and readability of the printed content.

[0011] The advantages of this utility model are:

[0012] 1. To prevent the packaging box from shifting during transportation, this utility model sets up a limiting mechanism. The packaging box is placed on the conveyor belt, and the first pneumatic cylinder is activated, causing the first pneumatic rod to move the L-shaped fixing frame and the limiting wheels. This causes the limiting wheels on both sides to move closer together until they contact the side walls of the packaging box. At this point, the first pneumatic cylinder stops operating, effectively limiting the packaging box. Under the action of the limiting wheels, the packaging box moves stably on the conveyor belt, thus preventing the packaging box from shifting during transportation and ensuring the quality and accuracy of the coding.

[0013] 2. After the packaging box is marked with ink, in order to quickly dry the ink, a drying mechanism is set up. The fourth motor is started to make the fan rotate. With the cooperation of the heating tube, the heated high-temperature gas can be blown into the air diffuser through the air supply hose. The air diffuser increases the contact area between the hot air and the surface of the packaging box, thereby enabling the ink to dry quickly and adhere firmly to the surface of the packaging box. This not only prevents the ink from flowing or spreading on the packaging box, causing the text to become blurred or deformed, but also ensures the clarity and readability of the marked content.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0022] Please see Figure 1-3As shown, a packaging box coding device includes two support plates 1. Two conveyor rollers 2 are mounted between the two support plates 1 via a rotating shaft, and the two conveyor rollers 2 are located at opposite ends of the support plates 1. A conveyor belt 3 is fitted onto the outer surface of the two conveyor rollers 2. A first motor 12 is mounted on one of the support plates 1, and the output end of the first motor 12 is connected to one end of one of the rotating shafts. A support plate 4 is fixed between the two support plates 1 and is disposed within the conveyor belt 3. A fixing block 5 is mounted on each of the two support plates 1, and a first pneumatic cylinder 6 is mounted on each of the two fixing blocks 5. A first pneumatic rod 7 is fitted to the actuating end of each of the two first pneumatic cylinders 6. An L-shaped fixing frame 8 is fixed to the end of each of the two first pneumatic rods 7. Multiple limit wheels 9 are rotatably mounted in each L-shaped fixing frame 8. Two fixing seats 10 are fixed to the top side of each support plate 1. Each fixing seat 10 has a rod hole, and a rod is inserted into each rod hole. A limiting rod 11 is provided, with one end of the limiting rod 11 fixed to the L-shaped fixing frame 8. The two limiting rods 11 are located on both sides of the first pneumatic cylinder 6. To prevent the packaging box from shifting during transportation, a limiting mechanism is set up. First, the packaging box is placed on the conveyor belt 3. Then, the first pneumatic cylinder 6 is activated, causing the first pneumatic rod 7 to drive the L-shaped fixing frame 8 and the limiting wheel 9 to move. This causes the limiting wheels 9 on both sides to move closer to each other until they contact the side walls of the packaging box. At this point, the first pneumatic cylinder 6 stops operating, thus effectively limiting the packaging box. Under the action of the limiting wheels 9, the packaging box moves stably on the conveyor belt 3, thereby preventing the packaging box from shifting during transportation and ensuring the quality and accuracy of the coding. By setting up a support plate 4, additional support is provided for the conveyor belt 3 to prevent it from sagging or deforming during operation, thus ensuring the smooth operation of the conveyor belt 3.

[0023] Please see Figure 5As shown, a second pneumatic cylinder 13 is mounted on each of the two support plates 1. A second pneumatic rod 14 is fitted to the actuating end of each of the two second pneumatic cylinders 13. A fixed plate 15 is fixedly connected to the top of each of the two second pneumatic rods 14. A second motor 17 is mounted on one of the fixed plates 15. A lead screw 16 is connected to the output end of the second motor 17, and the other end of the lead screw 16 is rotatably mounted on the other fixed plate 15. A movable block 18 is sleeved on the lead screw 16, and a coding device 19 is mounted on the bottom side of the movable block 18. Two guide rods 20 are fixedly connected between the two fixed plates 15, and the two guide rods 20 are respectively located on the two sides of the lead screw 16. On the side, each of the two guide rods 20 is fitted with a limiting block 21, and the limiting block 21 is fixed to the movable block 18. When the packaging box is being marked, the second pneumatic cylinder 13 operates, causing the second pneumatic rod 14 to drive the fixed plate 15 and the inkjet printer 19 to move up or down, thereby adjusting the height of the inkjet printer 19 to facilitate marking of packaging boxes of different heights. The second motor 17 operates, causing the lead screw 16 to rotate. With the cooperation of the guide rods 20 and the limiting block 21, the movable block 18 drives the inkjet printer 19 to move stably, thus facilitating marking of different positions on the packaging box as needed.

[0024] Please see Figure 4 As shown, two support plates 1 are fixedly connected to a support frame 22. Slide grooves 23 are provided on both sides of the support frame 22, and lifting plates 24 are installed in each of the two slide grooves 23. An air diffuser 25 is fixedly connected between the two lifting plates 24. Two third motors 26 are installed on the top side of the support frame 22. The output end of each third motor 26 is connected to a threaded rod 27, which is located within the slide groove 23 and passes through the lifting plate 24. During the drying operation, the third motors 26 operate, causing the threaded rod 27 to rotate, forcing the lifting plate 24 to move up or down along the slide groove 23. This causes the air diffuser 25 to move up or down accordingly, allowing the position of the air diffuser 25 to be adjusted according to the height of the packaging box, facilitating better drying of the ink after coding.

[0025] A heating box 28 is fixedly connected to the top side of the support frame 22. A heating tube 29 is installed inside the heating box 28. A gas supply hose 32 connects the heating box 28 and the air diffuser 25. A fourth motor 30 is installed on the top side of the heating box 28. A fan 31 is installed at the output end of the fourth motor 30. An air inlet pipe 33 is connected to the top side of the heating box 28. After the packaging box is marked, in order to dry the ink quickly, a drying mechanism is set up. The fourth motor 30 is started, and the fan 31 rotates. With the cooperation of the heating tube 29, the heated high-temperature gas can be blown into the air diffuser 25 through the gas supply hose 32. The air diffuser 25 increases the contact area between the hot air and the surface of the packaging box, so that the ink can be dried quickly and firmly adhered to the surface of the packaging box. This not only prevents the ink from flowing or spreading on the packaging box, causing the characters to become blurred or deformed, but also ensures the clarity and readability of the marked content.

[0026] Working Principle: The aforementioned automatic carton coding device is inconvenient for limiting the carton's position during transport, leading to cartons shifting and potentially causing skewed coding, thus affecting the quality and accuracy of the coding. Furthermore, existing automatic carton coding devices lack an effective drying mechanism; ink that hasn't dried properly can flow or spread, resulting in blurred and unclear characters, affecting the clarity and readability of the coding content. Therefore, this paper proposes a packaging box coding device to address these issues. To prevent cartons from shifting during transport, a limiting mechanism is implemented. First, the cartons are placed on conveyor belt 3... The first pneumatic cylinder 6 is activated, causing the first pneumatic rod 7 to move the L-shaped fixing frame 8 and the limiting wheel 9, thereby bringing the limiting wheels 9 on both sides closer together until they contact the side walls of the packaging box. At this point, the first pneumatic cylinder 6 stops operating, effectively limiting the packaging box. Under the action of the limiting wheels 9, the packaging box moves stably on the conveyor belt 3, thus preventing the packaging box from shifting during transportation and ensuring the quality and accuracy of the coding. By setting the support plate 4, additional support is provided for the conveyor belt 3 to prevent it from sagging or deforming during operation, thereby ensuring the smooth operation of the conveyor belt 3.

[0027] After the packaging box is marked, in order to quickly dry the ink, a drying mechanism is set up. The fourth motor 30 is started, which makes the fan 31 rotate. With the cooperation of the heating tube 29, the heated high-temperature gas can be blown into the air diffuser 25 through the air supply hose 32. The air diffuser 25 increases the contact area between the hot air and the surface of the packaging box, so that the ink can be dried quickly and firmly adhered to the surface of the packaging box. This not only prevents the ink from flowing or spreading on the packaging box, causing the text to become blurry or deformed, but also ensures the clarity and readability of the marked content. During the drying operation, the third motor 26 operates, which makes the threaded rod 27 rotate, forcing the lifting plate 24 to move up or down along the slide 23, and thus the air diffuser 25 moves up or down accordingly. This allows the position of the air diffuser 25 to be adjusted according to the height of the packaging box, so as to better dry the ink after marking.
