Description
Technical Field
[0001] The present application relates to the field of printing technology, and particularly relates to a full-width multi-functional printing device. Background Art
[0002] With the progress and development of the times, current consumers have diverse demands for products, which also puts higher requirements on product packaging and related printed matter. Currently, the market for variable printed graphics is growing faster and faster, and the low efficiency of traditional digital printing can no longer meet the market demand. Currently, widely used printing methods include offset printing, gravure printing, flexography, screen printing, letterpress printing, and digital printing. Among them, traditional offset printing is the most widely used, and its printing process is mature and stable, but the process is relatively complex. It is necessary to plate-making first and then print on an offset press. Therefore, once the content of the printed product is plate-making completed, it cannot be changed, and a single product can only print the same content, which is immutable during the printing process. In addition, with the gradual maturity of inkjet printing technology in digital printing in terms of printing speed, printing ink, and drying method, its current application is also becoming more and more extensive.
[0003] Based on the increasing market demand for variable and flexible printed products, in related technologies, a printing machine can integrate multiple printing methods. For example, an offset printing device can be integrated with an inkjet printing device to achieve diverse and flexible printing. However, in related technologies, a printing machine integrating multiple printing methods only simply combines one printing device with another printing device without making an adaptive match, resulting in a poor matching effect between different printing methods.

[0048] With the progress and development of the times, existing consumers have diverse demands for products, which also puts higher requirements on the packaging of products and related printed matter. Currently, the market growth of variable printed graphics and texts is getting faster and faster, and the low efficiency of traditional digital printing can no longer meet the market demand. Currently, widely used printing methods include offset printing, gravure printing, flexographic printing, screen printing, letterpress printing, and digital printing.
[0049] Based on the increasing market demand for variable and flexible printed products, a printing machine can integrate multiple printing methods. For example, an offset printing device can be integrated with a printing device to achieve diverse and flexible printing. However, in related technologies, a printing machine integrating multiple printing methods only simply combines one printing device with another printing device without making adaptive matching, resulting in a poor matching effect between different printing methods. More specifically, in related technologies, the printing widths corresponding to various integrated printing methods are different, which makes the width of the newly added printing device not match on the original basis, and full-width printing cannot be achieved.
[0050] In view of this, referring to Figures 1-6 , in an embodiment of the present utility model, a full-width multi-functional printing device 100 is provided, which includes a base body 110, an inkjet printing module 120, and an embossing module 130.
[0051] Specifically, referring to Figure 1 , the base body 110 includes a transport roller 111, and the transport roller 111 is adapted to transport printed products. It should be noted that the printed products in this application can be any products suitable for being printed, such as paper, packaging, etc., and the printed products can be unprinted printed products or printed completed printed products. Thus, it can be understood that the transport roller 111 is used to transport the printed products in a rolling manner, and the transport roller 111 can include multiple ones, so that the printed products can be transported by multiple transport rollers 111 in sequence, or the transport roller 111 can cooperate with the roller of the inkjet printing module 120 or the roller of the embossing module 130 to jointly transport the printed products. To achieve cooperation with the printing operation, the transport roller 111 can be arranged at the printing station, and in addition, the transport roller 111 can also be arranged upstream or downstream of the printing station of the printed products. In one transportation method, the outer periphery of the transport roller 111 can directly support and transport the printed products; in addition, a belt can also be wound between multiple transport rollers 111, and the printed products can be placed above the belt to achieve belt-type transportation.
[0052] Referring to Figures 1-2 , the inkjet printing module 120 is configured to inkjet the printed products transported by the transport roller 111 to print the printed products. The embossing module 130 includes an embossing roller 131, and the embossing roller 131 is configured to jointly apply pressure to the printed products with the transport roller 111 to print the printed products. Among them, the inkjet printing module 120 adopts a contactless, pressureless, and plate-free inkjet printing technology. Inkjet printing can involve computer control, and the liquid ink is converted into a high-speed and fine ink droplet stream through the inkjet holes 1261 of the inkjet printing module 120. These tiny ink droplets are precisely controlled and sprayed onto the printing substrate, thereby forming printed graphics and texts. It can eliminate the need for traditional printing plates and pressure during the printing process, making the printing process more flexible and efficient, and the graphic and text content can be changed according to actual needs. The inkjet printing module 120 can be monochromatic or multi-color, and the inkjet ink can be water-based or UV. The embossing module 130 realizes printing by the embossing roller 131 approaching the transport roller 111 relatively and squeezing the printed products. Thus, the embossing module 130 can specifically be any one of a lithographic printing press, a relief printing press, an intaglio printing press, and a hot stamping printing press. For the convenience of description, the following will be described with an example in which the embossing module 130 is a lithographic printing press. For other specific structures and printing function implementation methods of the inkjet printing module 120 or the embossing module 130, reference can be made to related technologies and will not be elaborated here.
[0053] Based on the above inkjet printing module 120 and embossing module 130, refer to Figure 1 , the inkjet printing module 120 and the embossing module 130 are arranged opposite to each other along the transportation direction X of the printed product. According to requirements, the opposite arrangement of the two modules along the transportation direction X of the printed product enables the printed product to be respectively subjected to the printing effects of the inkjet printing module 120 and the embossing module 130 during the transportation process by the transportation roller 111; or enables the two modules to work alternatively, that is, the printed product is only subjected to the printing effect of one of the inkjet printing module 120 and the embossing module 130. In particular, the printing width of the inkjet printing module 120 is greater than or equal to the printing width of the embossing module 130. Wherein, the printing width is the maximum width size that the printing effect of the inkjet printing module 120 or the embossing module 130 can cover. In actual work, the actual printed width size can be adjusted according to requirements. It can be understood that the above width setting enables the width of the inkjet printing module 120 to match the width of the embossing module 130. Thus, when the printed product is respectively subjected to the printing effects of the inkjet printing module 120 and the embossing module 130, the printed product can be printed in multiple ways according to requirements without losing the printing width, realizing the diversification of printing methods; when the printed product is only subjected to the printing effect of one of the inkjet printing module 120 and the embossing module 130, the widths corresponding to the two types of printing effects can be made consistent, realizing width standardization between different printing methods. In addition, when the original equipment only provides the embossing printing method, on this basis, one of the modules using the embossing method in the original equipment can be removed (specifically, the printing color group, plate cylinder, blanket cylinder, and impression cylinder 131 can be removed), and the inkjet printing module 120 can be replaced and installed in the original position. In this way, on the basis of the original embossing printing equipment, the full-width multi-functional printing device 100 integrating the inkjet printing module 120 and the embossing module 130 of the present application is formed.
[0054] According to the combination of the above embodiments, it can be seen that the full-width multi-functional printing device 100 of the present application includes a base body 110, a printing module 120, and an embossing module 130. The base body 110 includes a transport roller 111, and the transport roller 111 is adapted to transport printed products. The printing module 120 and the embossing module 130 are arranged opposite to each other along the transport direction X of the printed product, and the printing width of the printing module 120 is greater than or equal to the printing width of the embossing module 130. Compared with the printing machine in the related art that integrates multiple printing methods but does not make matching, the present application enables the width of the printing module 120 to match the width of the embossing module 130. Therefore, when the printed product is respectively subjected to the printing actions of the printing module 120 and the embossing module 130, the printed product can be printed in multiple ways according to requirements without losing the printing width, realizing the diversification of printing methods, and the widths corresponding to the two types of printing actions are consistent. Therefore, the full-width multi-functional printing device 100 of the present application can realize the diversification of printing methods without losing the printing width, and standardize the widths between different printing methods.
[0055] According to requirements, other matching relationships can also be realized between the printing module 120 and the embossing module 130. Specifically, on the one hand, the printing resolution of the printing module 120 can be greater than or equal to the printing resolution of the embossing module 130. According to requirements, the printing module 120 and the embossing module 130 can adopt any suitable printing resolution. For example, the printing resolution of the printing module 120 and / or the embossing module 130 can be any one of 600 dpi, 1200 dpi, 1800 dpi, and 2400 dpi. On the other hand, the printing color range of the printing module 120 can be greater than or equal to the printing color range of the embossing module 130. The above two aspects of settings are both based on the premise that the widths can match, so that the printing actions of the printing module 120 and the embossing module 130 can be further matched, thereby improving the consistency of the two types of printing actions.
[0056] See Figure 1, in some embodiments, the base 110 further includes a first base 112 and a second base 113. The first base 112 and the second base 113 are integrally connected and are oppositely arranged along the transportation direction X of the printed product. The inkjet printing module 120 is connected to the first base 112, and the embossing module 130 is connected to the second base 113. It can be understood that both the first base 112 and the second base 113 can serve as the installation structures for the printing modules (the inkjet printing module 120 and the embossing module 130). And the setting that the two are integrated structures and are respectively connected to the inkjet printing module 120 and the embossing module 130 can, on the one hand, improve the integration degree of the full-width multi-functional printing device 100, make the installation of the inkjet printing module 120 and the embossing module 130 stable, and reduce the shaking and deformation generated by them; on the other hand, it is also convenient for installation, saving the positioning and debugging operations during the installation of the inkjet printing module 120 and the embossing module 130. Further, in some embodiments, the first base 112 and the second base 113 have the same shape and structure. The above setting can make the installation structure of the base 110 have a higher standardization degree, and is beneficial to cost saving. And thus, on the premise that the original equipment includes multiple bases, and each base corresponds to installing a printing module (which can be a module with the same structure and function as the embossing module 130 of the present application), by removing the printing module originally installed on one of the original equipment bases (corresponding to the first base 112) and replacing and installing the inkjet printing module 120 of the present application at this position, the inkjet printing module 120 and the embossing module 130 arranged in parallel in the solution of the present application are formed. This setting makes the manufacturing and transformation of the full-width multi-functional printing device 100 of the present application convenient and has a lower cost.
[0057] To make the printing effect of the inkjet printing module 120 better. Refer to Figure 2 , in some embodiments, the inkjet printing module 120 further includes a suction drum 121. The number of the transport drums 111 is multiple. Along the transportation direction X of the printed product, the suction drum 121 is located between two transport drums 111 (it can be entirely between the two transport drums 111 or partially), so as to rotate together with each transport drum 111 and transport the printed product. The suction drum 121 has an outer peripheral wall 1211 extending in a ring shape, and the outer peripheral wall 1211 has a plurality of suction holes 12111. Thus, the suction drum 121 can be configured to generate an air flow, and the air flow flows along the suction holes 12111 in the direction pointing to the rotation axis of the suction drum 121, so as to adsorb the printed product on the suction drum 121. It can be understood that the suction drum 121 can generate an adsorption air flow, and through the action of the suction holes 12111, adsorb the printed product on the outer peripheral wall 1211 of the adsorption drum, so as to fix the position of the printed product during the printing process.
[0058] Further, refer to Figure 5 or Figure 6, in some embodiments, the suction drum 121 includes a cylinder body 1212, end caps 1213, and a suction assembly 1214. The cylinder body 1212 includes an outer peripheral wall 1211, and the outer peripheral wall 1211 has a plurality of suction grooves 12112 extending in a direction parallel to the rotation axis of the suction drum 121. The number of suction holes 12111 is plural, and each suction groove 12112 and each suction hole 12111 are distributed relatively along the circumferential direction of the rotation of the suction drum 121. Each suction groove 12112 communicates with at least one suction hole 12111. The end caps 1213 are connected to the ends of the cylinder body 1212 along the rotation axis, and the end caps 1213 define a suction chamber 1215. One side of the suction chamber 1215 communicates with each suction groove 12112, and the other side communicates with the suction assembly 1214. Among them, the suction assembly 1214 can be any device suitable for sucking air flow, for example, it can be a suction pipe or a vacuum adsorption device. It can be understood that the above structural arrangement can make the suction source located on both sides of the cylinder body 1212 and communicate with the adsorption chamber. The suction chamber 1215 further communicates with the suction holes 12111 and the outside of the suction drum 121 through the suction grooves 12112. Thus, after the suction assembly 1214 generates an adsorption effect, an adsorption effect can be formed at the position of the suction holes 12111, and then the suction effect on the printed matter can be realized.
[0059] Further, based on the setting of the suction drum 121, other cooperating components can also be provided. Specifically, on the one hand, referring to Figure 2 , in some embodiments, the printing module 120 further includes a blowing assembly 122. Along the radial direction of the rotation of the suction drum 121, the blowing assembly 122 is located on the side of the outer peripheral wall 1211 away from the rotation axis and upstream of the printing module 120. The blowing assembly 122 is configured to blow out air flow towards the outer peripheral wall 1211. The setting of the blowing assembly 122 can blow the printing plate against the surface of the suction drum 121, make the product adhere firmly, so as to better perform printing, and can also prevent the printed matter from warping. At the same time, setting the blowing assembly 122 upstream can also assist the suction drum 121 in the initial stage of adsorbing the printed matter. At this time, the adsorption force is relatively unstable, so the blowing assembly 122 needs to be provided for assistance. On the other hand, referring to Figure 2 , in some embodiments, the printing module 120 further includes a stop bar. Along the radial direction of the rotation of the suction drum 121, the stop bar is located on the side of the outer peripheral wall 1211 away from the rotation axis, and the stop bar 123 is configured to be able to block the movement of the printed matter towards the printing module 120. The blowing assembly 122 can be arranged around the printing module 120 and between the printing module 120 and the suction drum 121, so as to play a role in blocking the printed matter and prevent it from warping or detaching from the suction drum 121. On the other hand, in order to realize the drying effect of the ink ejected by the printing module 120, referring to Figure 2, in some embodiments, the inkjet printing module 120 further includes an infrared hot air drying component 124. Along the rotation radius of the air suction drum 121, the infrared hot air drying component 124 is located on the side of the outer peripheral wall 1211 away from the rotation axis and downstream of the inkjet printing module 120. Similarly, for the purpose of drying, refer to Figure 2 , in some embodiments, the inkjet printing module 120 further includes a UV drying component 125. Along the rotation radius of the air suction drum 121, the UV drying component 125 is located on the side of the outer peripheral wall 1211 away from the rotation axis and downstream of the inkjet printing module 120. Both the above-mentioned infrared hot air drying component 124 and the UV drying component 125 can match the width of the inkjet printing module 120 to achieve the drying of the full-width inkjet graphic ink.
[0060] For the specific structural arrangement of the inkjet printing module 120, refer to Figures 3-4 , in some embodiments, the inkjet printing module 120 includes a plurality of nozzles 126, and each nozzle 126 is used for jetting ink onto the printed product. Along the direction parallel to the rotation axis of the transport drum 111, the nozzles 126 are arranged oppositely. That is to say, each nozzle 126 can jointly perform the printing function, and the coverage range of each nozzle 126 can correspond to the printing width of the inkjet printing module 120. Based on this, refer to Figure 3 , in some embodiments, along the transport direction X of the printed product, the nozzles 126 are arranged side by side. This arrangement can make the layout of each nozzle 126 relatively simple, with low installation cost and small occupied space. Or, refer to Figure 4 , in other embodiments, along the transport direction X of the printed product, the nozzles 126 are arranged staggeredly. When the nozzle 126 itself needs to occupy a certain space, but in order to cover a larger width, and the spray holes 1261 of two adjacent nozzles 126 need to be continuously arranged, the above-mentioned staggered arrangement form can make the spray holes 1261 between the nozzles 126 continuously arranged without occupying extra lateral (along the direction parallel to the rotation axis of the transport drum 111) space, and can reduce the distance between the spray holes 1261. The spacing of the staggered nozzles 126 along the transport direction X is limited to not affecting the installation of the two nozzles 126, and the overall inkjet time matching and inkjet effect are uniformly coordinated by the inkjet control circuit, so as to complete the inkjet printing operation within the full-width range.
[0061] Furthermore, based on the above embodiments in which the nozzles 126 are arranged staggeredly, refer to Figure 4, in some embodiments, along the direction parallel to the rotation axis of the transport roller 111, each nozzle 126 includes a plurality of nozzle holes 1261 with a spacing of d1, and the spacing between the nozzle holes 1261 at the ends of adjacent nozzles 126 is d2, and it satisfies: d1 = d2. It can be understood that this setting makes the spacing between each nozzle hole 1261 equal and does not change the spacing of the nozzle holes 1261 at the junction position of two adjacent nozzles 126, so that the printing effect can be better. In other embodiments, based on the definitions of d1 and d2, in the embodiments where each nozzle 126 is arranged side by side, d1 = d2 can also be satisfied.
[0062] To meet more diverse printing requirements, refer to Figure 6 , in some embodiments, the printing module 120 includes a first nozzle group 127 and a second nozzle group 128. Both the first nozzle group 127 and the second nozzle group 128 include a plurality of nozzles 126. The first nozzle group 127 and the second nozzle group 128 are arranged opposite to each other along the transport direction X of the printed matter. Along the transport direction X of the printed matter, the nozzles 126 of the first nozzle group 127 are arranged side by side, and the nozzles 126 of the second nozzle group 128 are arranged staggeredly. According to the combination of the first nozzle group 127 and the second nozzle group 128 with different nozzle 126 arrangement forms, a full-width, full-resolution, and full-color inkjet printing module can be combined on the same printing unit. Specifically, in some embodiments, the printing widths of the first nozzle group 127 and the second nozzle group 128 can be the same (within the allowable error range), and different printing resolutions and / or different printing color ranges can be adopted between the first nozzle group 127 and the second nozzle group 128. Thus, the first nozzle group 127 and the second nozzle group 128 can jointly make the printing capacity range of the full-width multi-functional printing device 100 wider and meet more diverse printing requirements.

Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the application concept of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
