Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a paperboard inkjet printing device for corrugated boxes. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made of multi-layered cardboard with a unique wavy corrugated core. The lining paper on both sides works in conjunction with the core to form a stable structure. Thanks to the wavy shape of the corrugated core, the boxes have high strength, effectively dispersing external pressure and absorbing vibrations and impacts during transportation, protecting the contents. To facilitate inkjet printing on the cardboard, a cardboard inkjet printing device for corrugated cardboard boxes is needed.

[0003] A search revealed Chinese patent publication number CN222061553U, which discloses a cardboard inkjet printing device for corrugated boxes. The device includes a base plate and two support legs fixedly mounted on the bottom surface of the base plate. An inkjet printing mechanism and a positioning mechanism are located above the base plate. The positioning mechanism is situated to the left of the inkjet printing mechanism. The inkjet printing mechanism includes a lifting section and a mounting section. The technical advantage is that the inkjet printing mechanism enables inkjet printing on the surface of corrugated boxes during production. During printing, the printhead can be mounted, preventing ink from condensing and clogging the printhead when the printer is not in use. Furthermore, it can... The printhead can be replaced according to different coding requirements, making the inkjet printer more efficient in coding the surface of cartons. During installation, the printhead can be fixed by controlling two locking balls to extend to the front and rear sides of the locking sleeve, making installation convenient. The height of the inkjet printer can be adjusted by a lifting part. However, in actual use, this device can only code the top side of the carton. When multiple sides of the carton need to be coded, the position of the carton needs to be readjusted after coding and then coding again, which reduces the convenience of the device. Utility Model Content

[0038] 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 protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a cardboard inkjet printing device for corrugated boxes, comprising a fixed frame 1, a conveyor belt 3 fixedly connected to the top of the inner wall of the fixed frame 1, the conveyor belt 3 being able to transport cardboard boxes when activated, a mounting frame 4 fixedly connected to the top right side of the fixed frame 1, an ink cartridge 5 fixedly connected to the top of the mounting frame 4, an electric slide rail 6 fixedly connected to the middle of the inner wall of the mounting frame 4, a printhead 7 slidably connected to the inner side of the electric slide rail 6, the printhead 7 being able to use the ink in the ink cartridge 5 for inkjet printing when activated, and a bidirectional threaded rod 9 rotatably connected to the top of the inner wall of the mounting frame 4. The outer wall of the threaded rod 9 is threaded with a movable frame 10 on both the front and rear sides. Rotating the bidirectional threaded rod 9 can drive the movable frame 10 to move. The bottom of the movable frame 10 passes through the mounting frame 4 and is rotatably connected to a telescopic rod 11. The outer wall of the mounting frame 4 is fixedly connected with a motor 8 on both the front and rear sides. The output end of the motor 8 passes through the mounting frame 4 and is fixedly connected to the telescopic rod 11. Starting the motor 8 can drive the telescopic rod 11 to rotate. The outer side of the telescopic rod 11 is fixedly connected with a clamping plate 12. Multiple rubber balls 13 are rotatably connected around the outer wall of the clamping plate 12. A cleaning mechanism 2 is provided on the inner side of the fixed frame 1.

[0040] Specifically, after placing corrugated boxes on the surface of conveyor belt 3, starting conveyor belt 3 enables simultaneous conveying of multiple corrugated boxes. When the corrugated boxes are conveyed into the mounting frame 4, the electric slide rail 6 is first activated to precisely adjust the position of the printhead 7. Then, the printhead 7 is turned on, and the ink in the ink cartridge 5 is sprayed out to spray the corrugated boxes. If coding is required at different positions on the corrugated boxes, the bidirectional threaded rod 9 is rotated, and the moving frame 10 is displaced by the threaded connection. At the same time, the telescopic rod 11 is pulled to extend and retract, thereby driving the clamping plate 12 to securely hold the boxes. Afterward, the motor 8 is started, driving the telescopic rod 11 and the clamping plate 12 to rotate together to flip the boxes. Furthermore, the rubber ball 13 effectively improves the smoothness of the rotation during the fixing of the boxes, ensuring that the entire coding and flipping operation process is more efficient and stable.

[0041] Reference Figure 1 and Figure 5The cleaning mechanism 2 includes a hot air blower 201, which is fixedly connected to the right side of the fixed frame 1. The output end of the hot air blower 201 passes through the fixed frame 1 and is connected to a hot air pipe 203. When the hot air blower 201 is started, it can deliver hot air to the hot air pipe 203. A water tank 202 is provided on the right side of the inner wall of the fixed frame 1, and a reserved groove 204 is provided on the left side of the inner wall of the fixed frame 1. The water tank 202 and the reserved groove 204 pass through the left and right sides of the outer wall of the hot air pipe 203, respectively. The hot air pipe 203 can blow air and aerate to clean the conveyor belt 3. A cleaning roller 205 is rotatably connected to the left side of the inner wall of the fixed frame 1. The cleaning roller 205 can wipe the conveyor belt dry.

[0042] Specifically, after the hot air blower 201 is turned on, it will deliver hot air into the hot air pipe 203. The hot air will simultaneously blow onto the reserved groove 204 and the water tank 202. Cleaning liquid or clean water is pre-filled into the water tank 202. With the help of the hot air blowing, the liquid in the water tank 202 will generate an aeration phenomenon. Through this aeration, the conveyor belt 3 can be effectively cleaned. At the same time, when the hot air is discharged from the reserved groove 204, it can also dry the conveyor belt. Furthermore, as the conveyor belt 3 continues to convey, the cleaning roller 205 will further dry it. In this way, the conveyor belt 3 can always remain clean throughout the entire working process, ensuring the hygiene and efficiency of the conveying operation.

[0043] Reference Figure 2 , Figure 3 and Figure 5 The inner side of the reserved slot 204 is provided with a groove 16, and a filter screen 17 is fixedly connected to the inner side of the groove 16 to prevent impurities from entering the reserved slot 204; the outer wall of the fixed frame 1 is provided with handles 19 on all four sides, and screws 20 are threadedly connected to the left and right sides of the outer wall of the handles 19.

[0044] Specifically, the filter screen 17 in the groove 16 can prevent impurities from entering the reserved groove 204, the screw 20 can fix the handle 19, and the handle 19 can be used to hold and carry the device. By installing a threaded part in the positioning hole 22 on the positioning block 21, the device can be easily installed and fixed.

[0045] Reference Figure 1 , Figure 2 and Figure 3A controller 18 is fixedly connected to the center of the front side of the fixed frame 1. The controller 18 is electrically connected to the conveyor belt 3, the electric slide rail 6, the nozzle 7, the motor 8, and the hot air blower 201. The controller 18 can easily control the start of the conveyor belt 3, the electric slide rail 6, the nozzle 7, the motor 8, and the hot air blower 201. A knob 14 is rotatably connected to the front side of the mounting bracket 4. The outer side of the knob 14 passes through the mounting bracket 4 and is fixedly connected to the bidirectional threaded rod 9. Brackets 15 are fixedly connected to all four sides of the outer wall of the mounting bracket 4. The bottom of the brackets 15 is fixedly connected to the fixed frame 1.

[0046] Specifically, the controller 18 can easily control the start and operation of the conveyor belt 3, electric slide rail 6, nozzle 7 motor 8 and hot air blower 201, the knob 14 can easily drive the bidirectional threaded rod 9 to rotate, and the bracket 15 can improve the firmness of the fixation between the fixed frame 1 and the mounting bracket 4.

[0047] Working principle: Before using the device, corrugated paper is first placed on the surface of the conveyor belt 3. Then, the conveyor belt 3 is started to transport multiple corrugated cartons. When the corrugated cartons move into the mounting frame 4, the electric slide rail 6 is started to adjust the position of the print head 7, and the print head 7 is started to use the ink in the ink cartridge 5 for spraying. When it is necessary to print codes on different positions, the bidirectional threaded rod 9 is rotated to drive the moving frame 10 to move through the threaded connection. The telescopic rod 11 is pulled to extend and retract, thereby driving the clamping plate 12 to fix the cartons. Then, the motor 8 is started to drive the telescopic rod 11 and the clamping plate 12 to rotate, which can flip the cartons over and improve the smoothness of rotation when fixing them through the rubber ball 13.

[0048] Furthermore, starting the hot air blower 201 can blow hot air into the hot air pipe 203 to blow air into the reserved trough 204 and the water tank 202 at the same time. At this time, the cleaning liquid or water injected into the water tank 202 can be aerated with the blowing of hot air and cleaned by the aeration. As the hot air is discharged from the reserved trough 204, it can also dry the conveyor belt. As the conveyor belt 3 is conveyed, it is wiped dry by the cleaning roller 205, which can keep the conveyor belt 3 clean during operation.
