Description

Technical Field

[0001] This utility model relates to the field of color printing technology for cardboard boxes and paperboard, and in particular to a continuous cardboard box printing machine. Background Technology

[0002] The color printing machine uses modular product accessories to directly print the graphics and text on the computer onto the printing medium through the printhead of the inkjet printer. It is suitable for printing on any material, has a fast printing speed, and low printing cost, which can significantly reduce the cost of special printing on products. It is one of the commonly used equipment for carton manufacturers. It can perform continuous color printing processing on carton paperboard. For example, a continuous carton printing color printing machine with application number "202222696178.7" includes a machine table, and the top of the machine table is provided with two baffles. The two baffles are provided with limit mechanisms inside.

[0003] However, while it greatly enhances practicality, it requires manual placement of cardboard boxes at equal intervals on the conveyor belt for feeding and conveying. This can lead to operator fatigue due to frequent fixed operations and an inability to guarantee the equidistant effect, ultimately affecting the color printing processing results. At the same time, it cannot automatically control the clamping state of the cardboard boxes according to the movement position of the printing head, which requires the design of a separate drive structure for use, increasing costs and operational difficulty. Utility Model Content

[0004] This invention aims to address the shortcomings of existing technologies, such as the need for manual, sequential placement of cardboard boxes onto a conveyor belt for feeding and conveying. This process can lead to operator fatigue due to frequent, fixed operations and an inability to guarantee equidistant spacing, ultimately affecting the printing quality. Furthermore, the inability to automatically control the cardboard box clamping position based on the printing head's movement necessitates the design of a separate drive structure, increasing costs and operational complexity. Therefore, this invention provides a continuous cardboard box printing machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A continuous carton printing color printing machine includes a base and a vertical beam. The vertical beam is fixedly connected to the center of the upper left and right sides of the base. A top plate is fixedly connected to the upper end of the vertical beam. Multiple self-locking cylinders are fixedly connected at equal intervals to the upper end of the top plate. The output shaft of the self-locking cylinder is fixedly connected to a crossbeam. A feeding assembly is installed on the upper part of the base. Clamping assemblies are provided on both sides of the outer wall of the vertical beam.

[0006] To further improve the system, the feeding assembly includes a drive motor, a conveyor belt, pallets, and a hopper. The ends of the pallets on both sides are fixedly connected to the base by bolts. The hopper is fixedly attached to the rear upper side of the pallets. The power roller of the conveyor belt is connected to the output shaft of the drive motor through a sprocket and a chain. Push blocks are fixedly attached to both sides of the center of the outer wall of the conveyor belt. The drive motor is fixedly connected to the front right side of the base. The conveyor belt is installed inside the base.

[0007] To further improve the design, a groove is machined at the lower front end of the material box for the cardboard to be removed, and grooves are machined on both sides at the lower rear end of the material box for the pusher block to pass through.

[0008] Further improvements include a clamping assembly comprising a bracket, baffles, and slide cylinders. Multiple slide cylinders are fixedly connected to the outer wall of the base, and the inner walls of each slide cylinder are slidably connected to the bracket. A push plate is fixedly connected to the upper end of each bracket, and a rack is fixedly connected to the lower end of each bracket. A gear is meshed with the inner side of the rack, and the rotation shaft of the gear is rotatably connected to the housing. A column is fixedly connected to the lower end of the housing, and the end of the rack is movably connected to the housing via a spring. Multiple baffles are fixedly connected to both sides of the outer wall of the printing head, and a vertical rod is fixedly connected to the inner side of the upper end of the bracket.

[0009] Further improvements include a color printing head that is slidably connected to the outer wall of the crossbeam, and a rear-side traveling mechanism of the color printing head that is connected to the groove of the crossbeam.

[0010] Further improvements include the addition of a feature where both ends of the crossbeam are slidably connected to the vertical beam.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the cooperation between the drive motor, pusher block, material bin, cardboard box, and conveyor belt, starts the drive motor, causing the output shaft of the drive motor to drive the conveyor belt to rotate through the sprocket chain. The conveyor belt then drives the pusher block on its surface to rotate, causing the pusher block to insert into the groove below the rear end of the material bin. This pushes out the bottom layer of cardboard boxes from the groove below the front end of the material bin, realizing the automatic feeding process by pushing out the cardboard boxes one by one at equal intervals. This effectively avoids the problem of manually placing the cardboard boxes at equal intervals on the conveyor belt for feeding and conveying, which may cause operator fatigue due to frequent fixed operations and make it impossible to guarantee the equidistant effect, ultimately affecting the color printing processing effect.

[0012] Through the coordination of the printing head, support, vertical rod, baffle, gears, and springs, after completing a certain range of spraying, the printing head moves to one side. At this time, the baffle on the outer wall of the printing head pushes the vertical rod, causing one side of the support to move outward. The support on one side, through the coordination of gears, drives the other side of the support to move outward, thereby causing the push plates on both sides to unfold outward and no longer clamp the outer wall of the cardboard. Then, the conveyor belt drives the cardboard forward a certain distance, and then controls the traveling mechanism on the back of the printing head to move to the other side. During this process, the baffle of the printing head no longer abuts the position of the vertical rod, and the support and push plates are reset under the action of the springs, clamping the cardboard again. This achieves automatic clamping of the cardboard during spraying. When the cardboard is pushed, the push plates automatically release the clamping state, effectively avoiding the problem in the existing technology that cannot control the clamping state of the cardboard according to the movement position of the printing head, which leads to the need to design a specific drive structure for use, increasing costs and operational difficulties.

[0016] See attached document Figure 1-6 In this embodiment, the feeding assembly 3 includes a drive motor 302, a conveyor belt 303, pallets 304, and a hopper 306. The ends of the two pallets 304 are fixedly connected to the base 1 by bolts 301. The hopper 306 is fixedly connected to the rear side of the upper end of the pallet 304. The power roller of the conveyor belt 303 is connected to the output shaft of the drive motor 302 through a sprocket and a chain.

[0017] See attached document Figure 1-6In this embodiment, the clamping assembly 4 includes a bracket 401, a baffle 404, and a slide cylinder 405. Multiple slide cylinders 405 are fixedly connected to the outer wall of the base 1. The inner walls of the slide cylinders 405 are slidably connected to the bracket 401, providing support for the bracket 401. The side plates and lower horizontal lines of the bracket 401 are connected by bolts. When the spring force of the spring 410 is insufficient, the entire lower part of the bracket 401 can be removed and replaced. Push plates 403 are fixedly connected to the upper end of the bracket 401, and push plates 403 are fixedly connected to the lower end of the bracket 401. There is a rack 407, and a gear 409 is meshed on the inner side of the rack 407. The rotating shaft of the gear 409 is rotatably connected to the housing 406. A column 408 is fixedly connected to the lower end of the housing 406. The column 408 can stand on the ground to provide support for the housing 406. The end of the rack 407 is movably connected to the housing 406 through a spring 410. The elastic coefficient of the spring 410 can be determined according to the specific usage requirements. Multiple baffles 404 are fixedly connected to both sides of the outer wall of the color printing head 9. A vertical rod 402 is fixedly connected to the inner side of the upper end of the bracket 401.

[0018] Working principle: When this continuous carton printing machine is needed, the user first stacks the cardboard boxes 2 to be printed into the material bin 306. Then, the drive motor 302 is started, causing the output shaft of the drive motor 302 to drive the conveyor belt 303 to rotate via the sprocket and chain. The conveyor belt 303 then drives the pusher block 305 on its surface to rotate, causing the pusher block 305 to insert into the groove below the rear end of the material bin 306. This pushes out the bottom layer of cardboard boxes 2 from the groove below the front end of the material bin 306, thus automating the feeding process by pushing out the cardboard boxes 2 one by one at equal intervals. This is a significant improvement over the manual feeding process required for other methods. Placing the cartons on a conveyor belt for feeding and conveying can lead to operator fatigue due to frequent fixed operations and make it impossible to guarantee equidistant spacing, ultimately affecting the color printing processing effect. This invention solves the problem by inserting the pusher block 305 into the groove below the rear end of the material box 306, pushing out the bottom layer of cardboard 2 inside the material box 306 from the groove below the front end of the material box 306. This achieves the goal of pushing out the cardboard 2 one by one at equal intervals, effectively avoiding the problem of having to manually place the cardboard 2 at equal intervals on the conveyor belt for feeding and conveying, which can lead to operator fatigue due to frequent fixed operations and make it impossible to guarantee equidistant spacing, ultimately affecting the color printing processing effect.

[0019] After the cardboard 2 moves below the printing head 9, the conveyor belt 303 stops. The traveling mechanism behind the printing head 9 can be controlled to move laterally on the outer wall of the crossbeam 6. During the movement, color printing is applied to the upper surface of the cardboard 2. After a certain range of printing is completed, the printing head 9 moves to one side. At this time, the baffle 404 on the outer wall of the printing head 9 pushes the vertical rod 402 to move one side bracket 401 outward. The one side bracket 401 can drive the other side bracket 401 outward through the cooperation of gears 407 and 409, thereby causing the push plates 403 on both sides to unfold outward and no longer clamped on the outer wall of the cardboard 2. At this time, the conveyor belt 303 drives the cardboard 2 to move outward. The cardboard box 2 moves forward a certain distance, and then the traveling mechanism behind the printing head 9 is controlled to move to the other side. During this process, the baffle 404 of the printing head 9 no longer abuts against the position of the vertical rod 402, thereby causing the bracket 401 and the push plate 403 to reset under the action of the spring 410 and clamp the cardboard box 2 again. This achieves automatic clamping of the cardboard box 2 during spraying. When the cardboard box 2 is pushed, the push plate 403 automatically releases the clamping state, effectively avoiding the problem in the prior art that the clamping state of the cardboard box 2 cannot be controlled according to the moving position of the printing head 9, which leads to the need to design a specific drive structure for use, increasing costs and operational difficulties.

[0020] During the process, the specific height of the printing head 9 can be controlled by the self-locking cylinder 7 to adapt to the different size requirements of the carton 2. The user can remove the tray 304 and the material box 306 by loosening the bolt 301, replace the material box 306 and the tray 304 with the corresponding size requirements, install them on the base 1, and tighten the bolt 301 to complete the installation.

[0021] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
