Description

Technical Field

[0001] The utility model relates to the technical field of cardboard printing, in particular to a cardboard printing and conveying device. Background Art

[0002] The conveying and printing stages of the cardboard production process are crucial. During this process, the cardboard must be conveyed smoothly, continuously, and accurately to the printing area to ensure print quality and production efficiency. During the conveying and printing process, the cardboard is first separated by the paper feed system and fed into the conveyor system. A conveyor belt or rollers then smoothly transport the cardboard to the printing area. During conveyance, pressure rollers apply appropriate pressure to ensure flatness. Meanwhile, stoppers limit the cardboard, ensuring it maintains the correct position and orientation during conveyance. Once the cardboard reaches the printing area, the printing press's printing components begin to operate, transferring ink to the cardboard to create the pattern or text. During the printing process, the contact pressure and speed between the plate cylinder, rubber roller, and other components and the cardboard must be maintained constant to ensure uniform and consistent print quality.

[0003] The patent with publication date of March 22, 2024 and announcement number CN220641461U discloses a conveying device on a cardboard printing production line, which includes a support assembly, a conveying assembly, at least two lifting assemblies and at least one fixing mechanism, the support assembly includes a support frame, the conveying assembly includes two rotating rollers, a conveyor belt and a driving member, the distribution direction of the two rotating rollers is consistent with the cardboard conveying direction, the two rotating rollers are rotatably connected to the support frame, the conveyor belt is wrapped around the two rotating rollers, and the driving member can drive the rotating rollers to rotate; the distribution direction of the two lifting assemblies is consistent with the cardboard conveying direction, the lifting assembly includes a fixed base and a lifting member, the two lifting members are each located on a fixed base, one end of one lifting member is hinged to the fixed base, and the other end is hinged to the support frame, one end of the other lifting member is fixed to the fixed base, and the other end is hinged to the support frame, the fixing mechanism is fixed on the conveyor belt, and the fixing mechanism can fix the cardboard. This application has the effect of improving the inconvenience of cardboard conveying.

[0004] During the cardboard conveying printing process, there is often dust on the cardboard surface. The dust covering the cardboard surface will mix with the printing ink, affecting the purity of the ink, or form a "protective layer" on the cardboard surface. The ink is blocked by the dust and cannot fully contact the cardboard, which ultimately affects the printing quality of the pattern. The above solution considers using a fixing mechanism to fix the cardboard to improve the inconvenience of cardboard conveying, but ignores the need to clean the cardboard surface before printing to ensure printing quality.

[0005] Therefore, it is necessary to provide a cardboard printing and conveying device. Utility Model Content

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the accompanying drawings are intended to cover non-exclusive inclusions.

[0026] In order to improve the problem in the related art that dust on the cardboard surface mixes with the ink or forms a protective layer, and the ink cannot fully contact the cardboard surface, resulting in low printing quality, the embodiments of the present application provide the following solution.

[0027] Please also refer to Figure 1-Figure 5 , including: a frame 1, a control panel 2, a conveying mechanism 3, a printing mechanism 5 and a cleaning mechanism 4, the printing mechanism 5 includes a printing box 51, the cleaning mechanism 4 includes a cleaning box 41, a blower 42, a brush 43, a first motor 44, a first electric push cylinder 45 and a windshield 46, the conveying mechanism 3 is arranged on the frame 1, the printing box 51 is fixedly connected to the conveying mechanism 3, the cleaning box 41 is also fixedly connected to the conveying mechanism 3, and the cleaning box 41 is in contact with the printing box 51, the cleaning box 41 is provided with a through hole, and the blower 42 is fixed through the through hole It is connected to the cleaning box 41, and the wind shield 46 is fixedly connected to the part of the cleaning box 41 between the through hole and the printing box 51, and ash outlets are opened on both sides of the cleaning box 41. The first motor 44 is bonded to the output end of the first electric push cylinder 45, and the other end of the first electric push cylinder 45 is fixedly connected to the cleaning box 41. The brush 43 is fixedly connected to the output end of the first motor 44, and the control panel 2 is fixedly connected to the printing box 51. The blower 42, the first motor 44 and the first electric push cylinder 45 are all electrically connected to the control panel 2.

[0028] With such arrangement, the cardboard first enters the cleaning box 41 through the conveying mechanism 3. By inputting the thickness of the cardboard on the control panel 2, the first electric push cylinder 45 is adjusted, and the output end of the first electric push cylinder 45 moves toward the cardboard position. Then the first motor 44 starts to work, driving the brush 43 on the first motor 44 to start rotating, cleaning the dust on the surface of the cardboard. At the same time, the wind speed of the blower 42 is set and it is allowed to work. The wind blown by the blower 42 changes the wind direction after passing through the wind shield 46, gradually changing from the vertical direction to the horizontal direction, and the dust brought up by the brush 43 on the surface of the cardboard is blown out of the cleaning box 41 through the ash outlet. After the dust on the cardboard is cleaned, the cardboard is further transported to the printing box 51 through the conveying mechanism 3 for inkjet printing.

[0029] Optionally, in some embodiments, please refer to Figure 1 as well as Figure 3 The conveying mechanism 3 includes an input component 31, a conveyor belt 33, a conveyor roller 34, a first rotating shaft 35 and a second motor 36. The second motor 36 is arranged at both ends of the frame 1. The output end of the second motor 36 is fixedly connected to the first rotating shaft 35. The first rotating shaft 35 is also rotatably connected to the middle part of the frame 1. The conveyor roller 34 is sleeved on the first rotating shaft 35. The conveyor belt 33 is transmission-connected to the conveyor roller 34. The second motor 36 is electrically connected to the control panel 2.

[0030] With this arrangement, the cardboard is first adjusted and fixed in direction by the input component 31, and then transported to the conveyor belt 33 by the input component 31. The control panel 2 can be used to control the second motor 36 to change the conveying speed of the conveyor belt. The conveyor belt 33 is connected to the conveyor roller 34 for transmission. The second motors 36 at both ends of the frame 1 run synchronously at the same speed to control the rotation speed of the conveyor roller 34 and drive the conveyor belt 33 to move. The conveyor roller 34 in the middle part plays a supporting role on the one hand, and on the other hand, plays a role in rotating and driving the conveyor belt 33 to move.

[0031] Optionally, in some embodiments, please refer to Figure 1 、 Figure 3 as well as Figure 4 The input component 31 includes a servo motor 311, a rotating shaft 312, a rotating wheel 313 and a gravity sensor 314. The servo motor 311 is fixedly connected to the frame 1, and the rotating wheel 313 is sleeved and fixedly connected to the output end of the servo motor. The rotating shaft is rotatably connected to the frame, and a rotating wheel is sleeved and fixed on the rotating shaft.

The gravity sensor 314 abuts against the rotating wheel 313, and the gravity sensor 314 is electrically connected to the servo motor 311.

[0032] With this arrangement, when a cardboard is placed on the rotating wheel 313, the gravity sensor 314 senses the presence of the cardboard and transmits a gravity signal to the servo motor 311. The servo motor 311 starts working, driving the rotating wheel 313 to start rotating. With the help of the transmission wheel and belt, the rotating shaft 312 is driven to rotate, so that all the rotating wheels 313 roll to transport the cardboard toward the conveyor belt 33. When the cardboard is not in contact with the rotating wheel 313, the gravity sensor 314 does not receive the gravity signal, and the rotating wheel 313 does not rotate, thereby saving energy.

[0033] Optionally, in some embodiments, please refer to Figure 2 The conveying mechanism 3 also includes a limiting component 32, the limiting component 32 includes a limiting plate 321, a second electric push cylinder 322 and a support plate 323, the support plate 323 is fixedly connected to the frame 1, the second electric push cylinder 322 is fixedly connected to the support plate 323, the limiting plate 321 is fixedly connected to the output end of the second electric push cylinder 322, and the second electric push cylinder 322 is electrically connected to the control panel 2.

[0034] With this arrangement, when the cardboard passes through the input assembly 31, in order to prevent the change in the position of the cardboard from affecting the subsequent printing quality, when the cardboard moves on the roller, the control panel 2 controls the second electric push cylinder 322 to work, and its output end drives the limit plate 321 to move, thereby correcting the position and direction of the skewed rectangular cardboard. Then, the control panel 2 controls the second electric push cylinder 322 to move in the opposite direction, so that the limit plate 321 does not abut against the cardboard, but still has a small distance from the cardboard, so that the cardboard can move slightly within the range allowed by printing error.

[0035] Optionally, in some embodiments, please refer to Figure 3 The conveyor belt 33 is provided with a through hole, and a ventilation pipe 6 is movably connected in the cavity formed by the conveyor belt 33 and the conveyor roller 34. The ventilation pipe 6 is externally connected to a vacuum pump 7, and the vacuum pump 7 is electrically connected to the control panel 2.

[0036] With this arrangement, after the cardboard passes through the input assembly 31 and enters the conveyor belt 33, it will also pass through the printing mechanism 5 and the cleaning mechanism 4, which will cause the position of the cardboard to change. A through hole is opened on the conveyor belt 33, and a ventilation pipe 6 and a vacuum pump 7 are used in combination to use pressure to fix the cardboard on the conveyor belt 33. When the cardboard passes through the printing mechanism 5 and the cleaning mechanism 4, the position of the cardboard will not be easily changed, thereby ensuring printing quality.

[0037] Optionally, in some embodiments, please refer to Figure 3 The printing mechanism 5 also includes a printing unit 52, a second rotating shaft 53, a third motor 54, a lifting frame 55 and a cylinder 56. The printing box 51 is fixedly connected to the support plate 323, and the cylinder 56 is fixedly connected to the inner wall of the printing box 51 in an upside-down manner. The lifting frame 55 is fixedly connected to the output end of the cylinder 56, and the second motor 36 is fixedly connected to the lifting frame 55. The second rotating shaft 53 is fixedly connected to the output end of the second motor 36. The printing unit 52 is provided with a through hole and is sleeved on the second rotating shaft 53 through the through hole. The second motor 36 and the cylinder 56 are electrically connected to the control panel 2. The printing unit 52 uses quick-drying ink.

[0038] With this arrangement, the cylinder 56 is mainly used to adjust the height of the printing unit 52 up and down, the lifting frame 55 is used for loading, and the control panel 2 controls the speed of the third motor 54 according to the size and thickness of the cardboard and the speed of the conveyor belt 33, so that the printing unit 52 can adapt to the cardboard. When the cardboard passes through the printing box 51, the printing unit 52 rotates to realize printing on the cardboard. The printing unit 52 uses quick-drying ink, which improves work efficiency and creation speed, effectively reduces adhesion between ink marks, keeps the page neat and clear, and ensures printing quality.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
