Description

Technical Field

[0001] The utility model relates to the technical field of jet printing, in particular to a carton forming machine with jet printing equipment. Background Art

[0002] Cartons are the most widely used packaging products, usually used as wrapping for goods or as protective outer layers for items. Carton packaging machines, also known as carton forming machines or carton unpacking machines, are mechanical equipment that uses a single piece of carton sheet molded by a carton die-cutting machine as the packaging carton blank. After the carton is erected, it is sealed on the sides or bottom of the carton, allowing it to be directly used for product packaging. Although the carton forming machines currently on the market can achieve carton forming, their functions are relatively simple, and the last step before carton forming is to print the cardboard. Only after printing is completed can the carton be considered fully formed. The carton forming machines currently on the market need to first perform processes such as pressing, cutting, and punching on the cardboard, and then transfer the cardboard to the printer for printing. The turnover process not only wastes manpower and material resources, but also easily causes damage to the cardboard. Therefore, there is an urgent need for a carton forming machine with a printing component that can form the carton in one step. Utility Model Content

[0045] A retractable pull rod 30 is provided between the tool holder 23 and the horizontal base 20. In this embodiment, the pull rod 30 includes a driving member, which is a telescopic motor or a telescopic cylinder. The fixed end of the pull rod 30 is hinged to the horizontal base 20, and the telescopic end is hinged to the tool holder 23. Since the tool holder 23 is rotatably connected to the fixed seat 22, the pull rod 30 is retracted to drive the tool holder 23 to swing back and forth, and then drive the driven wheel 24 to move up and down, thereby realizing the up and down movement of the longitudinal cutter 27 to control the operation of the longitudinal cutter 27, and the cutting depth of the longitudinal cutter 27 can be adjusted at the same time.

[0046] A horizontal pressing piece 31 is provided at the bottom of the tool holder 23 along the front-to-back direction. The pressing piece 31 is fixed to the bottom of the tool holder 23 by fasteners. The pressing piece 31 is provided with an avoidance groove at the longitudinal cutting knife 27 to avoid interfering with the rotation of the longitudinal cutting knife 27. A waist-shaped hole is provided at the bottom of the tool holder 23.

A linear guide rail 16 that slides with the guide slider 15 is correspondingly provided on the mounting beam 26. The mounting beam 26 and the movable seat 14 are also connected by a gear-rack matching method, so that the movable seat 14 can stably reciprocate along the mounting beam 26. A retractable drive rod 17 is provided at the bottom of the movable seat 14. The retractable end of the drive rod 17 faces downward, and a longitudinal pressing wheel 18 is installed on the retractable end. The longitudinal pressing wheel 18 moves up and down by the retractable drive of the drive rod 17, so that the longitudinal pressing wheel 18 presses down and forms a longitudinal indentation on the cardboard.

[0051] The cross-cutting component d includes a support beam 36, which is connected to the frame. The support beam 36 is arranged in the same direction as the fixed beam 13.

The first support seat 37 is also provided with a drive for the second gear structure 40. The driving device 42 rotates the gear structure 40, so that the first support seat 37 can move back and forth stably along the support beam 36. A cross-cutter 43 is provided at the bottom of the first support seat 37. The cross-cutter 43 is a turntable cutter structure. The cross-cutter 43 is rotatably connected to the bottom of the first support seat 37. The cross-cutter 43 is transmitted to the second gear structure 40 through the synchronous gear transmission structure 44, so that the second gear structure 40 rotates and drives the synchronous gear transmission structure 44 to work. The synchronous gear transmission structure 44 drives the cross-cutter 43 to rotate. When the first support seat 37 moves back and forth along the support beam 36, the cross-cutter 43 contacts the cardboard and performs horizontal synchronous cutting.

The first conveyor roller 79, the second conveyor roller 80 and the third conveyor roller 81 are arranged in parallel with each other along the cardboard conveying direction. The paper to be printed is placed on the table 77 and is conveyed by three conveyor rollers and synchronous guide belts. The second support seat 76 is provided with a printing mechanism 74 below the table 77. The main components of the printing mechanism 74 are an ink supply mechanism and a nozzle 7 5. The ink supply mechanism supplies ink to the nozzle 75, which is used to spray ink. The printing mechanism 74 is conventional equipment, and its specific working principle and structure are not described in detail here. The table 77 has an operation port 771 between the third conveyor roller 81 and the second conveyor roller 80. The nozzle 75 of the printing mechanism 74 is located directly below the operation port 771. In other words, the nozzle 75 is positioned upward, so that the nozzle 75 can spray ink from the bottom to the top of the cardboard passing through the operation port 771, thereby printing the bottom surface of the cardboard. Because the nozzle 75 is positioned upward, ink only flows from the ink supply mechanism into the nozzle 75 when the nozzle 75 is spraying ink. After the ink is sprayed, the ink naturally flows down without accumulating in the nozzle 75, thereby greatly reducing the probability of clogging of the nozzle 75.

[0053] In addition, a heating mechanism may be added inside the nozzle 75 to prevent the ink from freezing inside the nozzle 75 and causing blockage when the ambient temperature is relatively cold. The specific structure of the heating mechanism will not be described in detail here.

[0054] In addition, an ink backflow prevention mechanism may be added inside the nozzle 75, such as setting a piston structure inside the nozzle 75 to absorb or press down the ink in the nozzle 75 through negative pressure or downward pressure. The specific structure of the backflow prevention mechanism is not described here.

[0055] The second support seat 76 is provided with a brush roller 84 between the first conveyor roller 79 and the second conveyor roller 80.

[0056] The table 77 is provided with a dust suction port 772 between the operating port 771 and the second conveying roller 80. The second support seat 76 is provided with a dust suction structure 78 below the dust suction port 772 to further remove dust from the cardboard after passing through the second conveying roller 80. The dust suction structure 78 is driven by a fan to perform negative pressure suction on the dust suction port 772 to achieve dust collection.

[0057] A first driving structure is provided on the second support seat 76, and the first driving structure includes a first driving member 82 and a first gear transmission structure 83. The output end of the first driving member 82 is connected to the roller body of the conveying roller through the first gear transmission structure 83. In this embodiment, the first gear transmission structure 83 includes a main gear, a belt, a tensioning pulley 32 and a driven pulley 24. The main gear is connected to the output end of the first driving member 82, and the driven pulley 24 is installed at the end of the roller body of the conveying roller. The belt connects the main gear, the tensioning pulley 32 and the driven pulley 24 in sequence to form a closed loop, so that transmission is formed between the first conveying roller 79, the second conveying roller 80 and the third conveying roller 81 to achieve synchronous rotation.

[0058] In this embodiment, the first conveying roller 79 and the second conveying roller 80 are both rubber rollers.

[0059] A second driving structure is also provided on the second support seat 76, and the second driving structure includes a second driving member 85 and a second gear transmission structure 86. The second gear transmission structure 86 includes a rack and a gear structure. The rack is laterally arranged on the second support seat 76, that is, the rack extends along the length direction of the conveying roller, and the gear structure is rotatably installed on the inkjet component e and engages with the rack. The output end of the second driving member 85 drives the gear structure to rotate, and the gear structure moves along the direction in which the rack is set, so that the gear structure drives the inkjet component e to perform lateral displacement, that is, the inkjet component e can move back and forth in a direction perpendicular to the conveying direction to realize back and forth printing in this direction.

[0060] The pressing mechanism 87 is located above the table 77. The pressing mechanism 87 includes a mounting seat 871. The mounting seat 871 is provided with a sun gear 8723 for pressing down. The mounting seat 871 is hinged with a lifting rod structure for fixing the sun gear 8723. The lifting rod structure includes a cross bar 8721 in the same direction as the length direction of the conveying roller and a swing arm 8722 located on both sides of the cross bar 8721. One end of the swing arm 8722 is hinged to the mounting seat 871, and the other end is hinged to the cross bar 8721. Multiple sun gears 8723 are connected in series on the cross bar 8721. The multiple sun gears 8723 are evenly and equidistantly distributed along the length direction of the cross bar 8721, so that the lifting rod structure can lift and press down relative to the mounting seat 871, thereby realizing the lifting and pressing down of the sun gear 8723.

[0061] A lifting rod structure and multiple sun gears 8723 located thereon serve as a downward pressure sun gear group 872. In this embodiment, a group of downward pressure sun gear groups 872 are respectively provided above the first conveying roller 79, the second conveying roller 80 and the third conveying roller 81, that is, there are three downward pressure sun gear groups 872. The cross bars 8721 of the three downward pressure sun gear groups 872 are arranged in the same direction as the corresponding conveying rollers, so that the first conveying roller 79, the second conveying roller 80 and the third conveying roller 81 all have downward pressure sun gears 8723, so that the cardboard can be positioned up and down to maintain stability.

[0062] A third driving structure is provided between each lifting rod structure and the mounting seat 871. The third driving structure includes a third driving member 873 and a hinge structure 874. The hinge structure 874 is installed between the lifting rod structure and the mounting seat 871, that is, the hinge structure 874 is installed at both ends of the cross bar 8721. The output end of the third driving member 873 is connected to the hinge structure 874. The third driving member 873 pushes and pulls the hinge structure 874. The hinge structure drives the cross bar 8721, so that the lifting rod structure can be lifted and pressed relative to the mounting seat 871. Since each lifting rod structure has its own third driving structure, the three downward-pressing sun gear groups 872 can be lifted and pressed individually or synchronously.

[0063] A first guide rail 88 is provided on the frame, and the first guide rail 88 extends perpendicular to the paper conveying direction. A first slider 89 is provided on the mounting seat 871, and the first slider 89 and the first guide rail 88 slide and cooperate with each other. A belt structure 91 is also provided on the frame along the first guide rail 88. A fourth driving member 90 is provided on the frame to drive the belt structure 91 to transmit. A synchronous wheel that cooperates with the belt structure 91 is provided on the first slider 89, so that the belt structure 91 and the synchronous wheel cooperate to assist the mounting seat 871 to move horizontally, and finally the downward pressure mechanism 87 can move back and forth horizontally.

[0064] A second guide rail 92 is provided on the frame, and the second support seat 76 is provided with a second slider 93 that slides with the second guide rail 92 to position the paper conveying direction as longitudinal. The second guide rail 92 is arranged along the transverse direction, and the second sliders 93 are distributed at the four corners of the second support seat 76. At the same time, the second guide rail 92 is provided with racks distributed in the same direction, and the second slider 93 is correspondingly provided with a gear that cooperates with the rack, so that the sliding of the second slider 93 is more stable. Finally, the second support seat 76 can move back and forth along the second guide rail 92, so that the inkjet assembly e can move back and forth horizontally. The inkjet assembly e and the downward pressure mechanism 87 can move horizontally synchronously, or they can move horizontally separately.
