Description

Technical Field

[0001] The invention relates to the technical field of printing machines, and in particular to a slotting structure of a water-based ink printing machine. Background Art

[0002] With the continuous development of the packaging industry, the quality and production efficiency requirements for packaging products such as cardboard are getting higher and higher. In the production of cardboard, it is not only necessary to print the cardboard, but also to open a variety of different fillets or notches on the cardboard so that the cardboard can be used normally after subsequent bending. Traditional printing and notching processes are often carried out separately, which not only increases the production process and reduces production efficiency, but also may cause errors in the conversion process of different processes, affecting product quality.

[0003] In order to meet the market demand for efficient and high-quality packaging products, the slotting structure of water-based ink printers came into being. This structure integrates printing and slotting functions into one device, greatly reducing production links and improving production efficiency. At the same time, through precise mechanical design and control systems, the accuracy of printing and slotting can be ensured, and the quality stability of products can be improved.

[0004] The existing slotting device uses a cutting roller for cutting and slotting. The cutting roller also plays the role of conveying while cutting. However, the cutting roller will squeeze the cardboard during conveying, causing the ink print on the cardboard to fade, seriously affecting the quality of the finished product. Summary of the invention The present invention provides a slotting structure for a water-based ink printer, which solves the problem in the related art that the printing quality of the paperboard is deteriorated due to the use of a cutting roller to convey the paperboard in the form of extrusion.

[0005] The technical solution of the present invention is as follows: A slotting structure for a water-based ink printing press, comprising: Printing rack; A negative pressure conveying member is arranged on the printing frame, and the negative pressure conveying member is used to drive the paperboard to move; A cutting roller is rotatably arranged on the printing frame, wherein the rotation axis of the cutting roller is not colinear with the conveying direction of the negative pressure conveying member, and the cutting roller does not abut against the paperboard; There are several cutters which are detachably arranged on the cutting roller. After the cutting roller rotates, the cutters abut against or cancel the abutment with the negative pressure conveying member. The cutters are used to cut cardboard.

[0006] As a further technical solution, the negative pressure conveying member includes: There are two conveying rollers, which are rotatably arranged on the printing frame; A conveyor belt, arranged on the two conveyor rollers, and having a plurality of openings; The adsorption plate is arranged on the printing frame, and has an exhaust space inside. The adsorption plate is located between the two conveying rollers. The top of the adsorption plate has a plurality of adsorption holes connected to the exhaust space. The adsorption plate adsorbs the cardboard through the openings.

[0007] As a further technical solution, the negative pressure conveying member further includes: A suction roller is rotatably arranged on the printing frame, the suction roller is located below the cutting roller and has the same height as the conveyor belt, the suction roller also has an exhaust space inside, and the outer wall of the suction roller also has a plurality of suction holes connected to the exhaust space; The vacuum member is arranged on the printing frame, the vacuum member is connected with the vacuum space, and is used to extract the gas in the vacuum space.

[0008] As a further technical solution, it also includes: A rotating shaft is arranged on the printing frame; There are several scrapers, and the scrapers are all rotatably arranged on the rotating shaft. After the scrapers rotate, they abut against or cancel the abutment with the adsorption roller. The scrapers are used to scrape off the cardboard adsorbed on the adsorption roller.

[0009] As a further technical solution, both ends of the scraper can abut against the adsorption roller. After the scraper rotates, the upper end or the lower end will abut against the adsorption roller. The side of the scraper abutting against the bottom of the adsorption roller has a drop hole, and the drop hole is used to allow the cut waste to leave the scraper.

[0010] As a further technical solution, both sides of the scraper have inclined surfaces. After the scraper rotates, one of the inclined surfaces abuts against or cancels the abutment against the adsorption roller. The inclined surface is used to cut off the connection between the paperboard and the adsorption roller.

[0011] As a further technical solution, it also includes: The limiting rod is detachably arranged on the printing frame, and the limiting rod is used to limit the rotation of the scraper after being installed.

[0012] As a further technical solution, the printing frame is provided with a plurality of mounting holes, and the plurality of mounting holes are used for mounting the limiting rods.

[0013] As a further technical solution, it also includes: A collecting bucket is located below the scraper and is used to collect waste materials cut off by the cutter.

[0014] As a further technical solution, it also includes: The blowing member is arranged above the conveyor belt and is used for drying the printed paperboard.

[0015] The working principle and beneficial effects of the present invention are: In the present invention, since the rotation axis of the cutting roller is not colinear with the conveying direction of the negative pressure conveyor and the cutter is detachably arranged on the cutting roller, this structure can drive the cardboard to move as a further technical solution when cutting the cardboard, and cut under stable conveying, which can reduce the shaking and deviation of the cardboard during the cutting process. In addition, multiple detachable cutters can be set according to different cutting patterns or slotting requirements, so that the cutting edge is more neat and the cutting quality is improved. The detachable design of the cutter is convenient for replacing the worn cutter, which reduces the difficulty of equipment maintenance. If the cutter is damaged or blunt, it can be replaced separately without replacing the entire cutting roller, which helps to reduce the maintenance cost of the equipment. At the same time, this structure is relatively simple, reduces the risk of failure caused by complex structures, and indirectly reduces the operation and maintenance costs of the equipment. The cutting roller in this structure does not abut against the cardboard, avoids squeezing and friction on the cardboard, and is suitable for cardboards of different thicknesses and materials. When facing different types of production tasks, there is no need to make large-scale adjustments to the equipment, only the setting of the cutter needs to be adjusted, which enhances the flexibility of the equipment.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention.

In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1~Figure 2 , which is the first embodiment of the present invention, proposes a slotting structure for a water-based ink printing machine, including: a negative pressure conveying member 2 is arranged on a printing frame 1, and the negative pressure conveying member 2 is used to drive the cardboard to move; a cutting roller 3 is rotatably arranged on the printing frame 1, and the rotation axis of the cutting roller 3 is not colinear with the conveying direction of the negative pressure conveying member 2, and the cutting roller 3 does not abut against the cardboard; there are a plurality of cutters 4, which are detachably arranged on the cutting roller 3, and after the cutting roller 3 rotates, the cutter 4 abuts against or cancels the abutment with the negative pressure conveying member 2, and the cutter 4 is used to cut the cardboard.

[0023] In this embodiment, since the rotation axis of the cutting roller 3 is not colinear with the conveying direction of the negative pressure conveyor 2 and the cutter 4 is detachably arranged on the cutting roller 3, this structure can drive the cardboard to move as a further technical solution when cutting the cardboard, and cut under stable conveying, which can reduce the shaking and deviation of the cardboard during the cutting process. In addition, multiple detachable cutters 4 can be set according to different cutting patterns or slotting requirements, so that the cutting edge is more neat and the cutting quality is improved. The detachable design of the cutter 4 is convenient for replacing the worn cutter 4, which reduces the difficulty of equipment maintenance. If the cutter 4 is damaged or blunt, it can be replaced separately without replacing the entire cutting roller 3, which helps to reduce the maintenance cost of the equipment. At the same time, this structure is relatively simple, reduces the risk of failure caused by complex structures, and indirectly reduces the operation and maintenance costs of the equipment. The cutting roller 3 in this structure does not abut against the cardboard, avoids squeezing and friction on the cardboard, and is suitable for cardboards of different thicknesses and materials. When facing different types of production tasks, there is no need to make large-scale adjustments to the equipment, only the setting of the cutter 4 needs to be adjusted, which enhances the flexibility of the equipment.

[0024] As a further technical solution, the negative pressure conveying member 2 includes: two conveying rollers 5, which are rotatably arranged on the printing frame 1; a conveyor belt 6 is arranged on the two conveyor rollers 5, and the conveyor belt 6 has a plurality of openings 7; an adsorption plate 8 is arranged on the printing frame 1, and the adsorption plate 8 has an exhaust space 9 inside, the adsorption plate 8 is located between the two conveying rollers 5, and the top of the adsorption plate 8 has a plurality of adsorption holes 10 connected to the exhaust space 9, and the adsorption plate 8 adsorbs the cardboard through the openings 7.

[0025] In this embodiment, the negative pressure conveying member 2 adopts a structure of two conveying rollers 5 rotatably arranged on the printing frame 1 and a conveyor belt 6 sleeved thereon, and this structure can provide stable support and transmission. Several openings 7 on the conveyor belt 6 cooperate with the adsorption plate 8, and the adsorption plate 8 is located between the two conveyor rollers 5, so that during the operation of the conveyor belt 6, the cardboard can be adsorbed at a suitable position, thereby ensuring the stability of the cardboard during the entire conveying process, reducing the shaking and offset of the cardboard, and facilitating the precise implementation of subsequent printing, slotting and other processes. There is an exhaust space 9 inside the adsorption plate 8, and there are several adsorption holes 10 on the top that are connected to the exhaust space 9, and the cardboard can be adsorbed through the openings 7 on the conveyor belt 6. This structural design can make the adsorption force distribution more uniform, and can effectively adsorb cardboards of different sizes and shapes. Uniform adsorption force helps to better fix the cardboard and prevent the cardboard from being displaced during cutting, printing and other operations, thereby improving the quality of printing and slotting.

[0026] As a further technical solution, the negative pressure conveying member 2 also includes: an adsorption roller 11 is rotatably arranged on the printing frame 1, the adsorption roller 11 is located below the cutting roller 3 and has the same height as the conveyor belt 6, the adsorption roller 11 also has an exhaust space 9 inside, and the outer wall of the adsorption roller 11 also has a plurality of adsorption holes 10 connected to the exhaust space 9; the exhaust member is arranged on the printing frame 1, the exhaust member is connected to the exhaust space 9, and the exhaust member is used to extract the gas in the exhaust space 9.

[0027] In this embodiment, the adsorption roller 11 is located below the cutting roller 3 and has the same height as the conveyor belt 6. There is an exhaust space 9 inside it, and there are a number of adsorption holes 10 on the outer wall that are connected to the exhaust space 9. This allows the adsorption roller 11 to adsorb the cardboard from the side in addition to the adsorption effect of the adsorption plate 8 on the bottom of the cardboard during the cardboard transportation process, thereby improving the comprehensiveness of the adsorption of the cardboard. The cardboard can be better fixed, especially during operations such as cutting and slotting, which can effectively prevent the edge of the cardboard from warping or shifting, thereby improving the cutting accuracy. The setting of the exhaust member provides exhaust power for the exhaust space 9 of the adsorption plate 8 and the adsorption roller 11. The gas in the exhaust space 9 is extracted by the exhaust member, which can enhance the adsorption force of the adsorption plate 8 and the adsorption roller 11. Stronger adsorption force helps to fix the cardboard more firmly. Whether it is a lighter cardboard or a smoother cardboard, it can be effectively adsorbed on the conveyor belt 6, reducing errors in the processing process and improving the working quality of the slotting structure of the water-based ink printer.

[0028] As a further technical solution, it also includes: a rotating shaft 13 is set on the printing frame 1; there are a plurality of scrapers 14, and the plurality of scrapers 14 are rotatably set on the rotating shaft 13. After the scraper 14 rotates, it abuts against or cancels the abutment with the adsorption roller 11, and the scraper 14 is used to scrape off the cardboard adsorbed on the adsorption roller 11.

[0029] In this embodiment, a plurality of scrapers 14 are rotatably arranged on the rotating shaft 13 and can abut or cancel the abutment with the adsorption roller 11, which provides a convenient way to clean the adsorption roller 11. When the adsorption roller 11 adsorbs impurities such as cardboard fragments during operation, the adsorbed cardboard can be easily scraped off by rotating the scraper 14 to abut against the adsorption roller 11. This structure can clean the adsorption roller 11 without complicated disassembly steps, reducing the time and workload of equipment maintenance. Timely cleaning of the cardboard adsorbed on the adsorption roller 11 is crucial for the stable operation of the equipment. If too much cardboard is adsorbed on the surface of the adsorption roller 11, its adsorption performance will be affected, thereby affecting the normal transportation and processing of the cardboard. The scraper 14 can effectively keep the surface of the adsorption roller 11 clean, so that the adsorption roller 11 always maintains a stable adsorption force during operation, thereby ensuring the operating stability of the entire ink printing machine slot structure and reducing paper jams, cardboard deviations and other faults caused by adsorption problems of the adsorption roller 11. Since the scraper 14 can clean the impurities on the adsorption roller 11 in time, the impurities are prevented from adhering to the surface of the adsorption roller 11 for a long time and causing wear and corrosion to it. This helps to extend the service life of the suction roller 11 and reduce the maintenance and replacement costs of the equipment. At the same time, it also helps to protect other components related to the suction roller 11, such as the suction member, because the good condition of the suction roller 11 can reduce the additional workload of the suction member and other components, indirectly extending the service life of these components.

[0030] As a further technical solution, both ends of the scraper 14 can abut against the adsorption roller 11. After the scraper 14 rotates, the upper end or the lower end will abut against the adsorption roller 11. The side of the scraper 14 abutting against the bottom of the adsorption roller 11 has a drop hole 15, and the drop hole 15 is used to allow the cut waste to leave the scraper 14.

[0031] In this embodiment, the design that both ends of the scraper 14 can abut against the adsorption roller 11 and the upper end or the lower end of the scraper 14 can abut against the adsorption roller 11 after the scraper 14 rotates expands the cleaning range of the scraper 14 on the adsorption roller 11. It can scrape off the debris such as cardboard adsorbed on the adsorption roller 11 more comprehensively to ensure the cleanliness of the surface of the adsorption roller 11. At the same time, the scraper 14 abuts against the lower side of the adsorption roller 11. When the scraper 14 scrapes off the cutting waste, the waste can directly leave the scraper 14 through the dropping hole 15, avoiding the accumulation of waste on the scraper 14. This not only makes the waste cleaning process more efficient, reduces the number of cleaning times of the scraper 14 increased due to waste accumulation, improves the overall working efficiency of the equipment, but also simplifies the equipment cleaning steps. The existence of the dropping hole 15 allows the cutting waste to leave the scraper 14 in an orderly manner, without the need to manually clean the waste on the scraper 14 or use additional tools to clean it. This reduces the difficulty of equipment cleaning, whether it is regular cleaning during equipment operation or deep cleaning after long-term operation, it can save time and labor costs. Timely cleaning of cutting waste is crucial to the stable operation of the equipment. If the waste is not removed from the scraper 14 in time, it may adhere to the suction roller 11 again or affect the normal operation of the scraper 14, thereby affecting the suction performance of the suction roller 11 or causing abnormal friction between the scraper 14 and the suction roller 11. The blanking hole 15 ensures that the waste is discharged smoothly, maintains the normal working state of the scraper 14 and the suction roller 11, and ensures the operating stability of the entire slotting structure of the ink printing machine.

[0032] As a further technical solution, both sides of the scraper 14 have inclined surfaces 16 . After the scraper 14 rotates, one inclined surface 16 abuts against or cancels the abutment against the suction roller 11 . The inclined surface 16 is used to cut off the connection between the paperboard and the suction roller 11 .

[0033] In this embodiment, the scraper 14 has inclined surfaces 16 on both sides. When the scraper 14 rotates, the inclined surfaces 16 can abut or cancel the abutment against the suction roller 11 to cut off the connection between the paperboard and the suction roller 11. The design of the inclined surfaces 16 allows the paperboard to be cut off in a gradual manner when the connection is cut off, which is more conducive to quickly and smoothly separating the connection between the paperboard and the suction roller 11 compared to a flat structure. This helps to improve the continuity of the production process, reduce the equipment stop time caused by the adhesion of the paperboard to the suction roller 11, and thus improve the overall production efficiency.

[0034] As a further technical solution, the limiting rod 17 is detachably arranged on the printing frame 1 , and the limiting rod 17 is used to limit the rotation of the scraper 14 after being installed.

[0035] In this embodiment, the limiting rod 17 is detachably arranged on the printing frame 1 and is used to limit the rotation of the scraper 14. This design can ensure that the scraper 14 remains fixed when it does not need to rotate, and effectively ensures that the scraper 14 will not rotate and disengage during operation.

[0036] As a further technical solution, the printing frame 1 is provided with a plurality of mounting holes 18 , and the plurality of mounting holes 18 are used to mount the limiting rods 17 .

[0037] In this embodiment, the mounting hole 18 can effectively limit the movement of the limiting rod 17, and at the same time, the assembly and disassembly is more convenient, thereby improving the user experience of the device.

[0038] As a further technical solution, it also includes: a collecting bucket 19 is located below the scraper 14, and the collecting bucket 19 is used to collect the waste cut by the cutter 4.

[0039] In this embodiment, the collecting bucket 19 can collect the cutting waste and residues scraped off by the scraper 14, which makes it more convenient and faster for the user to clean up, thereby improving the cleaning efficiency.

[0040] As a further technical solution, it also includes: a blowing member 20 is arranged above the conveyor belt 6, and the blowing member 20 is used to dry the printed cardboard.

[0041] In this embodiment, the blowing member 20 relies on the wind drawn out by the exhaust member to realize air supply, and delivers the wind to the cardboard that has just been printed, so as to dry the ink, prevent the pattern from being damaged during the cutting process, and improve the printing effect.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
