Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an efficient full-page printing device. Background Art

[0002] Full-page printing refers to a printing method in which the printing substrate is printed with the entire cardboard. As a printing method, its characteristics include low processes and no color difference. It is generally often used when making the cover of a picture album or a color box. Dark colors such as black and red are printed on the entire piece of paper. After full-page water-based printing of paper packaging boxes, a drying device is required to dry the ink to prevent pattern damage caused by friction between products after printing.

[0003] The publication number is: CN218857955U, which discloses an automatic drying device for the surface of full-page water-based printed products. The drying device can perform baking and preheating treatments on the upper and lower surfaces before printing paper packaging boxes through the heating box and heating plates installed on the connecting frame in the preheating box, so that the paper packaging boxes can have a certain initial temperature. In this way, during full-page water-based printing, the printed ink can be dried by its own temperature. Through the hot air blower, the air duct and the air jet head, hot air can be sprayed to perform the final drying treatment on the printed paper packaging boxes. Through the exhaust fan, the air flow in the drying box can be circulated and discharged, which is beneficial to accelerating the air flow and making the drying effect better. However, during the production and transportation of products, more dust or other sundries may adhere to the product surface. The above drying device only performs drying operations before product printing and does not clean the product surface. If the product surface has dust or sundries during printing, the product will become a defective product, thus affecting the printing production of the product.

[0004] Based on this, an efficient full-page printing device is now provided to eliminate the drawbacks of existing devices. Summary of the Utility Model

Detailed Description of the Invention

[0026] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0027] In one embodiment, as Figures 1-7 shown, an efficient full-page printing device includes a printing box 11. A pretreatment box 12 and a drying box 13 are respectively and communicatively connected to the input end and the output end of the printing box 11. A conveyor belt 14 is arranged inside the printing box 11, and the conveyor belt 14 penetrates through the pretreatment box 12 and the drying box 13. A heating plate 21 is fixedly arranged at a position corresponding to the middle of the conveyor belt 14 inside the pretreatment box 12. Two second exhaust ducts 29 are fixedly arranged inside the drying box 13. The input ends of the two second exhaust ducts 29 are respectively communicatively connected to the output ends of a communicating pipe, and the input end of the communicating pipe is communicatively connected to the output end of a second hot air blower 30. The second hot air blower 30 is fixedly arranged at the upper end of the drying box 13. A cleaning mechanism for cleaning the surface of the product is arranged inside the pretreatment box 12, and an exhaust mechanism for discharging air is arranged inside the drying box 13. The cleaning mechanism facilitates cleaning the surface of the product to be printed, and the exhaust mechanism facilitates discharging the used air and filtering and purifying the air at the same time;

[0028] The cleaning mechanism includes two cleaning disks 16 arranged symmetrically. A number of bristles are provided at the bottom ends of the cleaning disks 16. The upper end rotating shafts of the cleaning disks 16 are rotatably arranged in the mounting holes at the bottom end of the mounting plate. The upper end of the mounting plate is fixedly connected to the output end of the electric push rod 17. The electric push rod 17 is fixedly arranged at the upper end inside the pretreatment box 12. Second bevel gears are fixedly provided on the upper end rotating shafts of the cleaning disks 16. First bevel gears 18 are meshed with the second bevel gears respectively. The first bevel gears 18 are fixedly arranged on the transmission shaft. The two ends of the transmission shaft are rotatably provided with second rotating plates. The second rotating plates are fixedly arranged at the upper end of the mounting plate. A first gear is fixedly provided on the transmission shaft. A second gear is meshed with the first gear. The second gear is fixedly arranged at the output end of the second motor 19. The second motor 19 is fixedly arranged at the upper end of the mounting plate. The two ends of the conveyor belt 14 are respectively provided with a driving roller and a driven roller. The rotating shafts at the two ends of the driving roller and the driven roller are rotatably provided with first rotating plates. The first rotating plates are respectively arranged on one side of the drying box 13 and the conveyor belt 14. One end rotating shaft of the driving roller is fixedly connected to the output end of the first motor 15. The first motor 15 is fixedly arranged at the upper end of the support plate. The support plate is fixedly arranged on one side of the pretreatment box 12. During use, when it is necessary to clean the surface of the product to be printed, the product is placed on the upper end of the conveyor belt 14. Then the first motor 15 is started, so that the conveyor belt 14 drives the product to move. When the product moves below the cleaning disks 16, the second motor 19 is started. The second motor 19 drives the transmission shaft to rotate. The transmission shaft drives the two first bevel gears 18 to rotate. The two first bevel gears 18 respectively drive the two cleaning disks 16 to rotate, and the rotation directions of the two cleaning disks 16 are opposite. The cleaning disks 16 clean the attachments on the product surface through the bottom bristles. Limiting components for limiting the product are provided on both sides of the mounting plate. A removing component for removing and collecting the attachments on the product surface is provided inside the pretreatment box 12.

[0029] The limiting components include limiting rollers 20. The two limiting rollers 20 are arranged symmetrically. The rotating shafts at the two ends of the limiting rollers 20 are rotatably provided with third rotating plates. The third rotating plates are respectively fixedly arranged on both sides of the mounting plate. During use, when the product moves below the cleaning disks 16, the limiting rollers 20 can limit the product, preventing the product from moving when the cleaning disks 16 clean the product. At the same time, according to the height of different products, the electric push rod 17 can be started. The output end of the electric push rod 17 drives the mounting plate to move, so as to adjust the distance between the bottom end of the cleaning disks 16 and the upper end of the conveyor belt 14.

[0030] The cleaning component includes a first exhaust duct 22 and a gas collecting pipe 24. The first exhaust duct 22 is fixedly arranged on one of the third rotating plates. A fixed pipe is sleeved at the input end of the first exhaust duct 22. The fixed pipe is communicated with the output end of the first hot air blower 23. The first hot air blower 23 is fixedly arranged at the upper end of the pretreatment box 12. The gas collecting pipe 24 is fixedly arranged inside the pretreatment box 12. The gas collecting pipe 24 and the first exhaust duct 22 are arranged in a relative position. The output end of the gas collecting pipe 24 is communicated with a connection box 25. The connection box 25 is fixedly arranged on one side of the pretreatment box 12. A filter screen plate 26 is fixedly arranged inside the connection box 25. During use, when the product is cleaned by the cleaning tray 16, there is still a small amount of dust or impurities on the surface of the product. Subsequently, the conveyor belt 14 drives the product to move to one side of the first exhaust duct 22. At this time, the first hot air blower 23 is started. The output end of the first hot air blower 23 conveys hot air into the first exhaust duct 22. The first exhaust duct 22 discharges the air, so as to clean the dust or impurities on the product. At the same time, the heating plate 21 is started, so that the first exhaust duct 22 and the heating plate 21 cooperate to preheat the product. The hot air discharging the dust or impurities is blown into the gas collecting pipe 24. And because the gas collecting pipe 24 is communicated with the inside of the connection box 25, the hot air drives the dust or impurities to enter the connection box 25. At the same time, the filter screen plate 26 can intercept the dust or impurities. It should be noted that in this application, both the first hot air blower 23 and the second hot air blower 30 adopt existing components, which will not be elaborated here.

[0031] One side of the filter screen plate 26 is closely attached with a scraping rod 27. The scraping rod 27 is fixedly arranged at one end of a pull rod. The pull rod is slidably arranged in a rectangular through hole at the upper end of the connection box 25. A collecting box 28 is slidably arranged inside the connection box 25. During use, when it is necessary to clean the dust or impurities on one side of the filter screen plate 26, the pull rod is pulled. The pull rod drives the scraping rod 27 to move. Because the scraping rod 27 is closely attached to one side of the filter screen plate 26, the scraping rod 27 can clean the dust or impurities on one side of the filter screen plate 26. The cleaned dust or impurities fall into the collecting box 28 for collection.

[0032] The exhaust mechanism includes a gas collecting box 31 which is arranged inside the drying box 13. The gas collecting box 31 is located at the middle position of the conveyor belt 14. The output end of the gas collecting box 31 is communicated with the input end of the exhaust fan 32. The exhaust fan 32 is fixedly arranged at the bottom end inside the drying box 13. The output end of the exhaust fan 32 is provided with a purification component for purifying the air. During use, when the product after being cleaned and preheated moves into the printing box 11, the printing components inside the printing box 11 can print the product. Subsequently, the product is conveyed into the drying box 13 by the conveyor belt 14. When the product moves below the second exhaust duct 29, the second hot air blower 30 is started. The output end of the second hot air blower 30 conveys hot air into the two 39 (it seems there is a mistake here, should be specific parts). The second exhaust duct 29 discharges the hot air, so as to accelerate the drying of the printed pattern on the product surface. At the same time, the exhaust fan 32 is started, so that the used hot air enters the gas collecting box 31. The exhaust fan 32 conveys the air to the purification component inside for purification treatment.

[0033] The purification component includes a filter box 33. The input end of the filter box 33 is communicated with the output end of the exhaust fan 32. The filter box 33 is fixedly arranged at the bottom end inside the drying box 13. The output end of the filter box 33 is communicated with an air outlet pipe 35. A plurality of filter plates 34 are arranged inside the filter box 33. During use, when the exhaust fan 32 conveys the used air into the filter box 33, the air is discharged after being purified by the two filter plates 34, and the moisture and ink smell in the air can be adsorbed. It should be noted that in this application, the filter plates 34 can be selected from different materials according to actual use, such as water absorption plates, activated carbon plates, etc., which will not be elaborated here.

[0034] Adjusting plates 36 are closely arranged at both ends of the inlet and outlet of the pretreatment box 12 and the drying box 13. Two adjacent adjusting plates 36 are respectively fixedly arranged at both ends of the mounting frame 37. Threaded holes are arranged at the upper end of the mounting frame 37. Threaded rods 38 are in threaded fit with the threaded holes. One end of each threaded rod 38 is rotatably arranged in the mounting holes at the upper ends of the pretreatment box 12 and the drying box 13. A handwheel is arranged at one end of the threaded rod 38. During use, when printing products of different heights is required, the threaded rod 38 can be rotated. Under the action of the thread, the mounting frame 37 drives the two adjusting plates 36 to move, so as to adjust the height of the inlets and outlets of the pretreatment box 12 and the drying box 13, thereby reducing the circulation and discharge of the air inside the printing box 11, the pretreatment box 12 and the drying box 13.

[0035] The above embodiments disclose an efficient full-page printing device. When it is necessary to clean the surface of the product to be printed, the product is placed on the upper end of the conveyor belt 14. Subsequently, the first motor 15 is started, so that the conveyor belt 14 drives the product to move. When the product moves below the cleaning disk 16, the limiting roller 20 can limit the product to prevent the product from moving when the cleaning disk 16 cleans the product. At the same time, according to the height of different products, the electric push rod 17 can be started, and the output end of the electric push rod 17 drives the mounting plate to move, so as to adjust the distance between the bottom end of the cleaning disk 16 and the upper end of the conveyor belt 14. Subsequently, the second motor 19 is started, the second motor 19 drives the transmission shaft to rotate, the transmission shaft drives the two first bevel gears 18 to rotate, the two first bevel gears 18 respectively drive the two cleaning disks 16 to rotate, and the two cleaning disks 16 rotate in opposite directions. The cleaning disk 16 cleans the attachments on the product surface through the bottom brush. After the product is cleaned by the cleaning disk 16, there is still a small amount of dust or impurities on the product surface. Subsequently, the conveyor belt 14 drives the product to move to one side of the first exhaust duct 22. At this time, the first hot air blower 23 is started, and the output end of the first hot air blower 23 conveys hot air into the first exhaust duct 22. The first exhaust duct 22 discharges the air, so as to clean the dust or impurities on the product. At the same time, the heating plate 21 is started, so that the first exhaust duct 22 and the heating plate 21 cooperate to preheat the product. The hot air that discharges the dust or impurities blows the dust or impurities into the gas collecting pipe 24. And because the gas collecting pipe 24 is communicated with the inside of the connection box 25, the hot air drives the dust or impurities to enter the connection box 25. At the same time, the filter screen plate 26 can intercept the dust or impurities. When the product that has been cleaned and preheated moves into the printing box 11, the printing components inside the printing box 11 can print the product. Subsequently, the product is conveyed by the conveyor belt 14 into the drying box 13. When the product moves below the second exhaust duct 29, the second hot air blower 30 is started, and the output end of the second hot air blower 30 conveys heat into the two 39 (it should be noted that there may be an error here, assuming it is the second exhaust duct 29). The second exhaust duct 29 discharges the hot air, so as to accelerate the drying of the printed pattern on the product surface. At the same time, the exhaust fan 32 is started, so that the used hot air enters the air collecting box 31. When the exhaust fan 32 conveys the used air into the filter box 33, the air is discharged after being purified by the two filter plates 34, and the moisture and ink smell in the air can be adsorbed.

[0036] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
