[0001] This application claims priority to Chinese Patent Applications with application numbers 202420608119.6, titled "A Head Replacement Unit for a Printing Device", filed on March 26, 2024; 202420623353.6, titled "A Printing Device with Replaceable Heads", filed on March 26, 2024; 202410350771.7, titled "A Printing Device with Replaceable Heads and a Digital Enhancement Unit", filed on March 26, 2024; and 202410350764.7, titled "A Digital Enhancement Unit for a Printing Device", filed on March 26, 2024. The entire contents of these applications are incorporated herein by reference. Technical Field

[0002] This application relates to the field of printing devices, and particularly to a printing device. Background Art

[0003] Printed products are very common in daily life, such as leaflets, newspapers, product packaging, etc. These printed products are all printed by printing factories.

[0004] According to different requirements for printed products, the technological processes often vary. To meet the requirements of different customers, printing factories usually need to be equipped with multiple printing devices, such as printing devices for flexographic printing; printing devices for die-cutting; printing devices that can perform both flexographic printing and die-cutting. The printing of printed products includes multiple technological processes, and the arrangement order of different printing devices depends on the required technological order. Each printing device has a fixed direction for feeding and discharging products. After completing the printing of a batch of products, if the technological order of the next batch of products is different, such as being reversed, it is necessary to adjust the relative positions of the printing devices before printing the next batch of products. And according to different customer requirements, in addition to the technological order, the technologies to be used may also be different. Therefore, usually, not only the arrangement order of the printing devices needs to be adjusted, but also some printing devices may need to be replaced.

[0005] Printing devices are usually large in volume and weight, making it inconvenient to adjust their positions. The idle printing devices taken out of service will also occupy a large amount of space in the factory building, not only causing waste of resources but also affecting production efficiency.

Detailed implementation manners

[0078] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0079] It should also be understood that the term “and / or” used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0080] It should be noted that when an element is referred to as being “fixed to” or “disposed on” another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0081] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0082] In addition, in the description of the specification and the appended claims of the present application, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions, and should not be understood as indicating or implying relative importance.

[0083] The reference to "one embodiment" or "some embodiments" etc. described in the specification of the present application means that specific features, structures or characteristics described in connection with that embodiment are included in one or more embodiments of the present application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. Terms such as "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways. "A plurality" means two or more.

[0084] Figure 1 is a schematic structural diagram of a printing system in the related art. As Figure 1 shown, the printing system includes an unwinding device 01, a winding device 02 and a plurality of printing devices 03. The plurality of printing devices 03 are arranged in sequence between the unwinding device 01 and the winding device 02. The web released by the unwinding device 01 bypasses the functional rollers of the plurality of printing devices 03 in sequence. Only two functional rollers of each printing device 03 are schematically shown in the figure.

[0085] For Figure 1 the shown printing system, when printing, the unwinding device 01 releases the web, the winding device 02 winds up the web, and the flow direction of the web is from right to left. That is to say, the in-out product direction of this printing system is from right to left, and the in-out product direction of each printing device 03 therein is from right to left. When it is necessary to print another printed matter, if it is necessary to reverse the process sequence, it is necessary to completely change the arrangement order of the plurality of intermediate printing devices 03. Moreover, if the required process changes, just changing the flow direction of the web is not enough, and it may also be necessary to replace some of the printing devices. The equipment adjustment is inconvenient, the workload is large, and it will also cause some of the replaced printing devices to be idle, occupying a large space in the factory building, which has a greater impact on production efficiency.

[0086] Figure 2 It is a schematic structural diagram of a printing device provided by an embodiment of the present application. The printing device can be a device for performing printing processes, or a post-processing device for processing products after printing processes. The post-processing device can be, but is not limited to, a device for performing glazing processes, die-cutting processes, film laminating processes, cold stamping processes, hot stamping processes, and slitting processes.

[0087] As Figure 2 shown, the printing device includes a base 10, a plurality of functional rollers 40, and a plurality of heads 30 with different functions. The base 10 is selectively detachably connected to one of the plurality of heads 30, and the plurality of functional rollers 40 are detachably connected to the base 10. The base 10 has two sets of roller mounting positions. In the following two cases, the directions of the products entering and leaving the printing device are different:

[0088] The plurality of functional rollers 40 are installed at one set of roller mounting positions among the two sets of roller mounting positions;

[0089] The plurality of functional rollers 40 are installed at the other set of roller mounting positions among the two sets of roller mounting positions.

[0090] In the related art, since the installation position of the functional roller on the base is unique, the directions of the products entering and leaving are also fixed. In the embodiment of the present application, by providing two sets of roller mounting positions, during the use of the printing device, the plurality of functional rollers 40 can be installed at one of the two sets of roller mounting positions according to needs. After adjusting the plurality of functional rollers 40 to the other set of roller mounting positions, the directions of the products entering and leaving the printing device change, so that when it is necessary to reverse the process sequence, there is no need to adjust the position of the printing device, which is beneficial to improving production efficiency.

[0091] As an example, one set of roller mounting positions among the two sets of roller mounting positions includes at least a plurality of first roller mounting positions 50a, and one set of roller mounting positions among the two sets of roller mounting positions includes at least a plurality of second roller mounting positions 50b. The plurality of first roller mounting positions 50a and the plurality of second roller mounting positions 50b are arranged in a mirror image.

[0092] The first roller mounting positions 50a and the second roller mounting positions 50b are arranged in a mirror image, so that after adjusting the installation position of the functional roller 40, the directions of the products entering and leaving only change in a mirror image, which is beneficial to ensuring the accuracy of the process.

[0093] Exemplarily, the printing device includes a base 10, a plurality of functional rollers 40, and a plurality of printing heads 30 with different functions. The base 10 has a plurality of roller mounting positions, which include a plurality of first roller mounting positions 50a and a plurality of second roller mounting positions 50b. The plurality of first roller mounting positions 50a and the plurality of second roller mounting positions 50b are symmetrically distributed with respect to the same plane M. At least a part of the plurality of functional rollers 40 is selectively and detachably mounted at one of the first roller mounting positions 50a and the second roller mounting positions 50b.

[0094] The base 10 is selectively and detachably connected to one of the plurality of printing heads 30. That is, according to the needs of the process, a printing head 30 that meets the process requirements can be selected and installed on the base 10. After the required process changes, the printing head 30 can be replaced.

[0095] The top of the base 10 is used to carry the printing head 30. Exemplarily, the printing head 30 can be a flexographic printing head, a die-cutting machine head, etc. For printing devices with different processes, the printing heads are also different. Flexographic printing and die-cutting are relatively common processes in printing technology. Setting a flexographic printing head and a die-cutting machine head can improve the utilization rate of the printing device.

[0096] The printing device further includes an adapter plate 12 provided on the base 10 for connecting to other printing devices. The adapter plate 12 is provided on the base 10 to facilitate connection to other printing devices, so that a plurality of printing devices can be connected into one body.

[0097] By providing a plurality of functional rollers 40 in the base 10, where the plurality of roller mounting positions of the base 10 include a plurality of first roller mounting positions 50a and a plurality of second roller mounting positions 50b, at least a part of the plurality of functional rollers 40 is selectively and detachably mounted at one of the first roller mounting positions 50a and the second roller mounting positions 50b. That is, the functional rollers 40 can be installed at the first roller mounting positions 50a or the second roller mounting positions 50b according to needs. Since the plurality of first roller mounting positions 50a and the plurality of second roller mounting positions 50b are symmetrically distributed with respect to the same plane M, the direction of the incoming and outgoing products of the printing device can be changed by swapping the positions of the functional rollers 40, that is, installing the functional rollers 40 originally installed at the first roller mounting positions 50a to the symmetric second roller mounting positions 50b, and installing the functional rollers 40 originally installed at the second roller mounting positions 50b to the symmetric first roller mounting positions 50a. Thus, when it is necessary to reverse the process sequence, there is no need to adjust the position of the printing device, which is beneficial to improving production efficiency. Also, since the printing head 30 connected to the base 10 can be replaced, after reversing the process sequence, the printing head 30 can also be adjusted according to the specific process requirements, avoiding the idleness of the printing device, reducing the occupation of the factory space, and being beneficial to improving production efficiency.

[0098] AsFigure 2 As shown, the first roller mounting position 50a and the second roller mounting position 50b which is mirror - distributed with it are distributed at the same height.

[0099] The first roller mounting position 50a and the second roller mounting position 50b which are mirror images of each other are arranged at the same height, so that the first roller mounting position 50a and the second roller mounting position 50b are mirror - distributed. After adjusting the position of the functional roller 40, the height of the functional roller 40 will not change, and only the in - out product direction of the printing equipment will change mirror - image - wise. For example, the in - out product direction changes from right - to - left to left - to - right, which is beneficial for arranging products between adjacent printing equipments.

[0100] As Figure 2 shown, the multiple roller mounting positions further include a third roller mounting position 50c. The third roller mounting position 50c is located on the symmetry plane of the multiple first roller mounting positions 50a and the multiple second roller mounting positions 50b, and some of the multiple functional rollers 40 are mounted on the third roller mounting position 50c.

[0101] Since the third roller mounting position 50c is located on the symmetry plane of the multiple first roller mounting positions 50a and the multiple second roller mounting positions 50b, during the process of changing the in - out product direction of the printing equipment, the functional roller 40 mounted on the third roller mounting position 50c does not need to adjust its position, which can reduce the workload when adjusting the printing equipment.

[0102] Printing equipments usually have multiple functional rollers 40 with different functions. For example, a laminating roller for providing pressure to press different films together, a cooling roller for cooling the film, and a traction roller for providing traction force. The positions where different functional rollers 40 are arranged may be different.

[0103] In some examples, the cooling roller can be mounted on the third roller mounting position 50c.

[0104] Since the structure of the cooling roller is relatively complex, and in order to better cool the film, the size of the cooling roller is usually relatively large. Therefore, the disassembly and assembly of the cooling roller are more troublesome than those of other functional rollers 40. Mounting the cooling roller on the third roller mounting position 50c can avoid the disassembly and assembly of the cooling roller and reduce the workload of adjusting the in - out product direction.

[0105] The first roller mounting position 50a and the second roller mounting position 50b are arranged in a one-to-one correspondence. In some examples, among a part of the first roller mounting positions 50a and the corresponding second roller mounting positions 50b, only one of them may be provided with the functional roller 40. For this part of the first roller mounting positions 50a and the corresponding second roller mounting positions 50b, when it is necessary to adjust the direction of the incoming and outgoing products, the functional roller 40 can be adjusted from the first roller mounting position 50a to the second roller mounting position 50b, or from the second roller mounting position 50b to the second roller mounting position 50b. Among another part of the first roller mounting positions 50a and the corresponding second roller mounting positions 50b, both may be provided with the functional roller 40. For this part of the first roller mounting positions 50a and the corresponding second roller mounting positions 50b, when it is necessary to adjust the direction of the incoming and outgoing products, the functional roller 40 located at the first roller mounting position 50a and the functional roller 40 located at the second roller mounting position 50b can be interchanged.

[0106] In the embodiment of the present application, the roller mounting position refers to the area on the base 10 for arranging the functional roller 40. In order to mount the functional roller 40, a mounting structure, such as a hole structure, can be provided at the roller mounting position.

[0107] Figure 3 It is a schematic structural view of a base provided by an embodiment of the present application. As Figure 3 shown, the base 10 includes two first mounting plates 111 arranged oppositely, and the functional roller 40 is located between the two first mounting plates 111.

[0108] Figure 4 It is a front view of a base provided by an embodiment of the present application. As Figure 4 shown, at the roller mounting position, the first mounting plate 111 has a first mounting hole 111a, and the first mounting hole 111a is used to mount the functional roller 40.

[0109] The two first mounting plates 111 are used to provide support for both ends of the functional roller 40. Using the first mounting hole 111a to mount the functional roller 40 not only has a simple structure, but also is convenient in design, and the position arrangement is relatively flexible.

[0110] Figure 5 It is a partial structural view of a first mounting plate provided by an embodiment of the present application. As an example, as Figure 5 shown, the first mounting plate 111 has a first chute 111b, and the first chute 111b is located between the first roller mounting position 50a and the second roller mounting position 50b that are mirror images of each other. One end of the first chute 111b is communicated with the first mounting hole 111a located at the first roller mounting position 50a, and the other end of the first chute 111b is communicated with the first mounting hole 111a located at the second roller mounting position 50b.

[0111] The first mounting holes 111a that are mirror images of each other are connected through the first sliding groove 111b. In this way, when adjusting the position of the functional roller 40, the functional roller 40 can be directly slid from the first roller body mounting position 50a to the second roller body mounting position 50b, or from the second roller body mounting position 50b to the first roller body mounting position 50a, making the adjustment of the functional roller 40 more convenient.

[0112] In some examples, the base 10 further includes a first slider 112, and the first slider 112 is located in the first sliding groove 111b. The first slider 112 can move along the first sliding groove 111b into the first mounting hole 111a. The functional roller 40 is connected to the first slider 112.

[0113] By providing the first slider 112 to support the functional roller 40, it is possible to prevent the functional roller 40 from directly contacting the first mounting plate 111, thereby avoiding wear on the functional roller 40 during the process of adjusting its position.

[0114] In addition, providing the first slider 112 is also beneficial to improving the running stability of the functional roller 40. For example, after providing the first slider 112, the first slider 112 can also serve as a bearing seat, facilitating the installation of a bearing to support the functional roller 40.

[0115] Figure 6 It is a schematic structural diagram of a first slider provided by an embodiment of the present application. As Figure 6 shown, the outer side wall of the first slider 112 has a second groove 112a, and the edge of the first mounting plate 111 at the first sliding groove 111b is located in the second groove 112a.

[0116] The first slider 112 is embedded in the first sliding groove 111b, and a part of the first mounting plate 111 is located in the second groove 112a, forming a fit with the second groove 112a. During the movement of the first slider 112 along the first sliding groove 111b, it can provide guidance, making the movement of the first slider 112 smoother and also preventing the first slider 112 from disengaging from the first sliding groove 111b.

[0117] The second groove 112a can be connected end to end, that is, the second groove 112a extends a full circle around the circumference of the first slider 112, so that when the first slider 112 moves into the first mounting hole 111a, the hole wall of the first mounting hole 111a is located in the second groove 112a.

[0118] In some examples, a locking mechanism is provided on the first slider 112. The locking mechanism is used to lock the first slider 112 at the first roller body mounting position 50a or the second roller body mounting position 50b.

[0119] When adjusting the position of the functional roller 40, after moving the first slider 112 to the first roller mounting position 50a or the second roller mounting position 50b, the first slider 112 is locked by a locking mechanism to prevent displacement of the first slider 112 and the functional roller 40 during the operation of the printing device, which may affect the operation of the printing device.

[0120] As an example, the first mounting plate 111 further has a plurality of first connection holes 111c, and the first connection holes 111c are distributed around the first mounting hole 111a. The locking mechanism includes a first bolt for connecting with the first connection holes 111c.

[0121] As Figure 6 shown, the first slider 112 may have a plurality of second connection holes 112b, and the second connection holes 112b penetrate through two opposite side walls of the second groove 112a. After the first slider 112 moves to the first mounting hole 111a, the second connection holes 112b are aligned with the first connection holes 111c, and the first bolt is inserted into the first connection holes 111c and the second connection holes 112b to lock the first slider 112.

[0122] In other examples, the side wall of the first slider 112 may have a plurality of bumps, and the bumps have third connection holes, that is, the third connection holes are located outside the second groove 112a. After the first slider 112 moves to the first mounting hole 111a, the third connection holes are aligned with the first connection holes 111c, and the first bolt is inserted into the first connection holes 111c and the third connection holes to lock the first slider 112.

[0123] As Figure 4 shown, the bottom of the base 10 has height adjusting feet 11. The height adjusting feet 11 are used to adjust the placement height of the printing device so that the heights of adjacent printing devices match.

[0124] There may be a plurality of height adjusting feet 11. By changing the heights of different height adjusting feet 11, the levelness of the printing device can be adjusted to make the functional roller 40 horizontal.

[0125] Figure 7 is the front view of a base provided by an embodiment of the present application. As Figure 7 shown, a bracket 113 may further be provided on the first mounting plate 111, and the bracket 113 is detachably connected to the first mounting plate 111. A functional member 1131 is mounted on the bracket 113.

[0126] In some examples, the functional member 1131 may include a roller body, for example, an extrusion roller that cooperates with an adjacent functional roller 40 to extrude a product; in other examples, the functional member 1131 may include a curing device, which is used to process a product sprayed with glue to cure the glue. The functional member 1131 can be configured according to the specific printing equipment and the functions to be achieved.

[0127] As an example, the plurality of functional rollers 40 at least include a fixed traction roller 41 disposed on the base 10. The printing equipment includes a bracket 113 hingedly disposed on the base 10, and an adjusting member 1132 disposed on the base 10 for adjusting the bracket 113. Exemplarily, the adjusting member may be a traction cylinder with a telescopic rod connecting the bracket 113. The functional member 1131 can be a movable traction roller, and the movable traction roller is disposed on the bracket 113 through a shaft rod and is tangent to the fixed traction roller 41 during operation.

[0128] The structure on the first mounting plate 111 for connecting with the bracket 113 can also be symmetrically arranged with respect to the plane M, so that when adjusting the direction of the incoming and outgoing products, the position of the bracket 113 can be adjusted mirror-symmetrically.

[0129] As Figure 7 shown, an adjusting slide rail 114 can also be installed on the first mounting plate 111. A second slider 115 is slidably connected to the adjusting slide rail 114, and a locking member is disposed between the second slider 115 and the adjusting slide rail 114. For example, the locking member can be a screw. By turning the screw to make the screw abut against the adjusting slide rail 114, the second slider 115 is locked relative to the adjusting slide rail 114; when it is necessary to adjust the position of the second slider 115 on the adjusting slide rail 114, the screw can be loosened. A functional roller 40 is installed on the second slider 115. As Figure 7 shown, two functional rollers 40 can be installed on the second slider 115.

[0130] As an example, the adjusting slide rail 114 is symmetrically arranged with respect to the plane M.

[0131] In some other possible implementation manners, one set of roller body mounting positions in the two sets of roller body mounting positions may further include a fourth roller body mounting position, and the other set of roller body mounting positions in the two sets of roller body mounting positions may further include a fifth roller body mounting position. The symmetry plane of the fourth roller body mounting position and the fifth roller body mounting position does not coincide with the symmetry plane of the first roller body mounting position 50a and the second roller body mounting position 50b. That is to say, the fourth roller body mounting position and the fifth roller body mounting position may not be symmetric with respect to the plane M. For some functional rollers 40, their functions can still be achieved even if there is a certain deviation in the mounting positions on the base 10. In addition, when there are limitations in the mirror arrangement of the roller body mounting positions, the roller body mounting positions can also deviate from the mirror positions by a certain distance.

[0132] Figure 8 It is a schematic structural diagram of a printing device provided by an embodiment of the present application. Figure 8 At least the machine head 30 is omitted. As Figure 8 shown, the printing device includes a base 10, a connection structure 20, and a plurality of machine heads 30 with different functions. The connection structure 20 is connected to the base 10, and the connection structure 20 is configured to be detachably connected to any one of the plurality of machine heads 30, and at most one machine head 30 is connected to the connection structure 20.

[0133] By providing the base 10, the connection structure 20, and the plurality of machine heads 30 with different functions, and connecting the machine head 30 and the base 10 through the connection structure 20. Since the connection structure 20 and the machine head 30 are detachably connected, accordingly, according to specific process requirements, a machine head 30 with a corresponding function can be selected from the plurality of machine heads 30 and connected to the connection structure 20. When other processes need to be implemented, it can be replaced with a machine head 30 with other functions, avoiding the idle of the printing device, reducing the occupation of space, and avoiding the waste of resources.

[0134] Figure 9 It is a schematic structural diagram of a connection structure provided by an embodiment of the present application. As Figure 9 shown, in some examples, the connection structure 20 includes a fixed part 21 and a movable part 22. The movable part 22 is connected to the fixed part 21, and the movable part 22 can move relative to the fixed part 21. The fixed part 21 is connected to the base 10, and the movable part 22 is connected to the machine head 30.

[0135] The installation position of the machine head 30 has a certain influence on its function. For example, it may affect the accuracy of the process. Different machine heads 30 may have different installation positions due to differences in structure or function. By installing the machine head 30 on the base 10 through the connection structure 20, since the movable part 22 can move relative to the fixed part 21, the movable part 22 can be moved to adjust the position of the machine head 30, improving the accuracy of the installation position of the machine head 30, and thus improving its process accuracy.

[0136] Figure 10 It is an exploded structural diagram of a connection structure provided by an embodiment of the present application. As Figure 10 shown, in this printing device, the movable part 22 and the fixed part 21 are in sliding fit.

[0137] After the machine head 30 is connected to the movable part 22, the position of the machine head 30 is adjusted by sliding the movable part 22. The sliding motion mode is relatively stable, suitable for fine-tuning the position of the machine head 30, and improving the position accuracy of the machine head 30.

[0138] As an example, as Figure 10As shown, the fixed part 21 includes a horizontal slide rail 211, and the fixed part 21 cooperates with the horizontal slide rail 211.

[0139] With the cooperation of the horizontal slide rail 211, the fixed part 21 can move along the horizontal slide rail 211.

[0140] The machine head 30 usually includes a number of roller shafts. After the machine head 30 is installed in place, the roller shafts are usually required to be horizontal. The horizontally arranged horizontal slide rail 211 can also be used as a reference to improve the levelness of the roller shafts.

[0141] In some examples, the horizontal slide rail 211 can be directly installed on the base 10. Exemplarily, the horizontal slide rail 211 is detachably connected to the base 10, for example, by bolts. The accuracy of the horizontal slide rail 211, such as dimensional accuracy, will affect the installation accuracy of the machine head 30. Using a horizontal slide rail 211 with higher accuracy is beneficial to improving the installation accuracy of the machine head 30 and also makes the sliding of the movable part 22 smoother. The horizontal slide rail 211 is detachably connected to the base 10, which can facilitate the replacement of the horizontal slide rail 211. For example, the horizontal slide rail 211 is replaced when it shows wear beyond the allowable limit.

[0142] The horizontal slide rail 211 can also be fixedly connected to the base 10, for example, by welding.

[0143] Exemplarily, the horizontal slide rail 211 can be a rectangular slide rail, a circular slide rail, an H-shaped slide rail, that is, the cross-section of the slide rail can be rectangular, circular or H-shaped.

[0144] Two or more horizontal slide rails 211 can be provided. The multiple horizontal slide rails 211 are arranged in parallel at intervals to make the sliding of the fixed part 21 smoother.

[0145] In this example, as Figure 10 shown, the fixed part 21 further includes a bottom plate 212. The bottom plate 212 is detachably connected to the base 10, and the horizontal slide rail 211 is located on the surface of the bottom plate 212.

[0146] The bottom plate 212 can provide a relatively flat installation foundation for the horizontal slide rail 211, facilitating the arrangement of the horizontal slide rail 211.

[0147] As Figure 1 shown, the bottom plate 212 can have a plurality of bottom plate fixing holes 212a, and the bottom plate 212 and the base 10 can be connected by bolts.

[0148] The horizontal slide rail 211 and the bottom plate 212 can be detachably connected or fixedly connected.

[0149] In some examples, the fixed part 21 further includes two limit members 213. The limit members 213 are located on the side of the horizontal slide rail 211, and the two limit members 213 are spaced along the horizontal slide rail 211. The limit members 213 are used to limit the movement range of the movable part 22 along the horizontal slide rail 211.

[0150] In this example, each limit member 213 may include at least one limit rod, and the limit rod is arranged perpendicular to the surface of the bottom plate 212. The limit rod is arranged near the end of the horizontal slide rail 211 and has a certain gap with the horizontal slide rail 211. In some examples, each limit member 213 may include two limit rods, and the two limit rods are respectively located on both sides of the horizontal slide rail 211.

[0151] By arranging the limit members 213 to limit the movement range of the movable part 22 along the horizontal slide rail 211, it is possible to prevent the movable part 22 from detaching from the end of the horizontal slide rail 211.

[0152] Since the limit members 213 are not installed on the horizontal slide rail 211 but are arranged on the bottom plate 212, and there is still a gap between the limit members 213 and the horizontal slide rail 211, when adjusting the position of the movable part 22 along the horizontal slide rail 211, even if the movable part 22 accidentally collides with the limit members 213, the acting force will not directly act on the horizontal slide rail 211, and deformation of the horizontal slide rail 211 affecting the accuracy can be avoided.

[0153] In some other possible implementation manners, the limit members 213 may also be connected to the horizontal slide rail 211, for example, detachably connected or fixedly connected to the horizontal slide rail 211, or integrally formed with the horizontal slide rail 211. It is easy to understand that when assembling two components that are relatively close to each other to another structure, these two components are more likely to interfere with each other during the assembly process, affecting the assembly efficiency. In this example, the limit members 213 and the horizontal slide rail 211 can be assembled first, and then the horizontal slide rail 211 and the bottom plate 212 are assembled together, avoiding mutual interference and making the assembly easier to operate.

[0154] Exemplarily, when the limit members 213 are arranged on the horizontal slide rail 211, the limit members 213 may be stoppers, retaining rings, etc. located at both ends of the horizontal slide rail 211.

[0155] In some examples, limit members 213 may be respectively provided corresponding to each horizontal slide rail 211. For example, two limit members 213 are respectively arranged corresponding to each horizontal slide rail 211.

[0156] As Figure 10 shown, the movable part 22 includes a second mounting plate 221. One side of the second mounting plate 221 is in sliding fit with the fixed part 21, and the other side of the second mounting plate 221 is used to connect to the machine head 30.

[0157] The structure of the second mounting plate 221 is simple, which can provide a relatively complete and flat surface for the installation of the machine head 30, enabling the machine head 30 to remain stable.

[0158] Exemplarily, the machine head 30 can be connected to the second mounting plate 221 by bolts.

[0159] On the side of the second mounting plate 221 for connecting the machine head 30, multiple groups of bolt holes 221a can be distributed. Each group of bolt holes 221a is at least used to connect to one machine head 30. For machine heads 30 with different functions, there may be differences in structure such as shape and size. By setting multiple groups of bolt holes 221a on the second mounting plate 221, when replacing the machine head 30, bolt holes 221a at appropriate positions can be selected to install the machine head 30, enabling the second mounting plate 221 to adapt to different machine heads 30.

[0160] Such as Figure 10 As shown, on the side of the second mounting plate 221 close to the bottom plate 212, a third slider 222 can be provided. The third slider 222 is in sliding fit with the horizontal slide rail 211. The third slider 222 can be located between two limit members 213. When the second mounting plate 221 slides relative to the bottom plate 212, the third slider 222 moves between the two limit members 213.

[0161] As an example, on the side of the third slider 222 away from the second mounting plate 221, a first groove 222a can be provided, and the horizontal slide rail 211 is located in the first groove 222a.

[0162] Such as Figure 10 As shown, the connection structure 20 of this printing device further includes a driving part 23. The driving part 23 is respectively connected to the fixed part 21 and the movable part 22. The driving part 23 is used to drive the movable part 22 to move. The driving part 23 is provided to facilitate adjusting the position of the movable part 22 relative to the fixed part 21, so as to achieve the purpose of adjusting the position of the machine head 30.

[0163] As an example, the driving part 23 can include a lead screw mechanism. The lead screw mechanism can include a lead screw 231 and a connecting block 232. One of the lead screw 231 and the connecting block 232 is connected to the fixed part 21 or the base 10, and the other of the lead screw 231 and the connecting block 232 is connected to the movable part 22.

[0164] Such as Figure 10 As shown, in this example, the connecting block 232 is connected to the second mounting plate 221, and the lead screw 231 is connected to the bottom plate 212. The lead screw 231 is arranged parallel to the horizontal slide rail 211. The lead screw 231 is in threaded fit with the connecting block 232. By rotating the lead screw 231, the connecting block 232 can be moved along the lead screw 231, thereby driving the second mounting plate 221 to move along the horizontal slide rail 211.

[0165] The lead screw mechanism not only moves smoothly but also has high adjustment accuracy, which is beneficial for fine adjustment of the position of the head 30. Additionally, due to the characteristics of the lead screw mechanism itself, the power is generally transmitted from the lead screw 231 to the connecting block 232, that is, the lead screw 231 can drive the connecting block 232 to move, while it is difficult for the connecting block 232 to drive the lead screw 231 to rotate. This enables the mechanism to remain stable after the position of the second mounting plate 221 is adjusted in place and is not prone to displacement.

[0166] As an example, as Figure 10 shown, a lead screw mounting block 2121 is connected to one side of the bottom plate 212, and the lead screw mounting block 2121 has a through hole. The lead screw 231 is inserted into the through hole of the lead screw mounting block 2121 and is in clearance fit with the through hole, enabling the lead screw 231 to rotate relative to the lead screw mounting block 2121.

[0167] The driving part 23 may further include a rotating rod 233, which is rotatably connected to the lead screw mounting block 2121. The rotating rod 233 is arranged parallel and spaced apart from the lead screw 231. The rotating rod 233 is in transmission connection with the lead screw 231. For example, the rotating rod 233 and the lead screw 231 can be connected by gear transmission, or by belt transmission, or by chain transmission. In this example, the rotating rod 233 and the lead screw 231 are connected by belt transmission. The belt connecting the rotating rod 233 and the lead screw 231 can be a V-belt, which is not prone to slipping and has a relatively stable transmission ratio. The lead screw 231 and the rotating rod 233 can be respectively connected with belt pulleys, and a belt is wound around the belt pulleys. Figure 10 The belt is omitted in [the figure] and only the belt pulleys are shown.

[0168] As Figure 10 shown, a first handle 2331 can be provided at the end of the rotating rod 233 to facilitate the operator to turn the rotating rod 233.

[0169] In some examples, the lead screw 231 is located between the fixed part 21 and the movable part 22.

[0170] As Figure 10 shown, the connecting block 232 is located on the side of the second mounting plate 221 close to the bottom plate 212. The lead screw 231 is located between the bottom plate 212 and the second mounting plate 221. This not only makes full use of the space and reduces the space occupied by the printing equipment, but also the second mounting plate 221 and the bottom plate 212 can provide a certain degree of protection for the lead screw 231, preventing impurities from adhering to the surface of the lead screw 231 and preventing foreign objects from getting stuck between the lead screw 231 and the connecting block 232, which may affect the normal function of the lead screw mechanism.

[0171] In some examples, the connection structure 20 further includes a locking portion, which is connected to one of the fixed portion 21 and the movable portion 22, and the locking portion is used to lock the movable portion 22.

[0172] As an example, the locking portion may include a brake, which is sleeved outside the lead screw 231, and the brake is used to lock the lead screw 231. After rotating the lead screw 231 and adjusting the machine head 30 in place, locking the lead screw 231 through the brake can further prevent the loosening of the lead screw mechanism and improve the stability of the printing device.

[0173] In some possible implementation manners, the locking portion may also include pressing blocks, which are distributed at the edge of the second mounting plate 221. For example, the locking portion may include a plurality of pressing blocks, and the plurality of pressing blocks are spaced apart along the edge of the second mounting plate 221. The pressing blocks are movably connected to the bottom plate 212. For example, the pressing blocks may be connected to the bottom plate 212 through bolts. By tightening the bolts, the pressing blocks are pressed against the surface of the second mounting plate 221 away from the bottom plate 212, and the second mounting plate 221 is locked by the downward pressure and friction force of the pressing blocks, thereby locking the movable portion 22.

[0174] Figure 11 and Figure 12 is a schematic structural diagram of a printing device provided by an embodiment of the present application. Figure 13 is a schematic structural diagram of a connection structure provided by an embodiment of the present application. As Figure 13 shown, in this printing device, the connection structure 20 includes a fixed portion 21, a movable portion 22, and a driving portion 23.

[0175] Figure 14 is an exploded structural diagram of a connection structure provided by an embodiment of the present application. As Figure 14 shown, the fixed portion 21 of the connection structure 20 includes two horizontal slide rails 211, and the two horizontal slide rails 211 are respectively connected to the base 10. As an example, the horizontal slide rail 211 is a circular horizontal slide rail, that is, the cross section of the horizontal slide rail 211 is circular.

[0176] The movable portion 22 of the connection structure 20 includes a second mounting plate 221 and a fourth slider 223, and the fourth slider 223 is connected to one side of the second mounting plate 221. The fourth slider 223 is sleeved outside the horizontal slide rail 211 and is in clearance fit with the horizontal slide rail 211, so that the fourth slider 223 can slide along the horizontal slide rail 211.

[0177] The driving portion 23 includes a lead screw 231 and a connection block 232, the lead screw 231 is connected to the movable portion 22, and the connection block 232 is connected to the base 10. The lead screw 231 is located on the side of the fixed portion 21 away from the movable portion 22.

[0178] As Figure 14As shown, anti-collision blocks 2231 are provided on the outer sides of the two fourth sliders 223. The anti-collision blocks 2231 are connected to the fourth sliders 223. There is a gap between the anti-collision blocks 2231 and the base 10. The anti-collision blocks 2231 can limit the movement range of the movable part 22 relative to the horizontal slide rail 211.

[0179] The anti-collision blocks 2231 can be flexible members, such as rubber members, to play a buffering role and avoid hard collisions between the connection structure 20 and the base 10.

[0180] In this example, the movable part 22 further includes two baffles 224, which are arranged on the side of the second mounting plate 221 away from the fourth slider 223. The two baffles 224 are arranged at intervals along the extending direction of the horizontal slide rail 211. Exemplarily, the two baffles 224 are parallel.

[0181] The lead screw 231 can be inserted into the two baffles 224 and is arranged parallel to the horizontal slide rail 211. The lead screw 231 and the baffle 224 are locked to each other in the axial direction of the lead screw 231, and the lead screw 231 is rotationally engaged with the baffle 224. That is to say, the lead screw 231 can rotate relative to the baffle 224, but their relative positions remain unchanged in the axial direction of the lead screw 231.

[0182] As Figure 14 shown, the lead screw 231 penetrates through the baffle 224, and one end of the lead screw 231 is threadedly connected to the connection block 232, so that during the rotation of the lead screw 231, the lead screw 231 can move relative to the connection block 232 along the axial direction of the lead screw 231, thereby driving the movable part 22 to slide along the horizontal slide rail 211. By providing the two baffles 224, the head 30 can be limited.

[0183] The baffle 224 can also be provided with a second mounting hole 224a, and the second mounting hole 224a can be used to connect with the head 30. To meet the installation requirements of different heads 30, the second mounting hole 224a can be provided with multiple second mounting holes 224a, and the distribution positions of the second mounting holes 224a can be set according to the head 30. When installing the head 30, the head 30 can be selectively connected to some of the second mounting holes 224a among the multiple second mounting holes 224a.

[0184] Exemplarily, at least one baffle 224 is detachably connected to the second mounting plate 221. For example, the baffle 224 is connected to the second mounting plate 221 by bolts. This can facilitate the disassembly and assembly of the head 30.

[0185] In this example, both ends of the lead screw 231 extend relative to the baffle 224. One end of the lead screw 231 is engaged with the connecting block 232, and the other end of the lead screw 231 is connected with a second handle 2311. By providing the second handle 2311, the lead screw 231 can be conveniently rotated manually to adjust the position of the movable part 22 on the horizontal slide rail 211.

[0186] In this example, the machine head 30 has a jack, and the lead screw 231 passes through the jack and is in clearance fit with the jack.

[0187] By providing a jack on the machine head 30 to accommodate the lead screw 231, protection can be provided for the lead screw 231 to prevent the lead screw 231 from being exposed and knocked to deform, and also prevent sundries from adhering to the surface of the lead screw 231 and affecting the rotation of the lead screw 231.

[0188] In this example, the two baffles 224 are respectively detachably connected to the second mounting plate 221. When it is necessary to replace the machine head 30, at least one of the two baffles 224 can be removed. For example, remove one of the two baffles 224 that is far from the connecting block 232. During the removal process, the lead screw 231 can be rotated to separate the lead screw 231 from the connecting block 232, and the lead screw 231 can be pulled out of the jack, so that the baffle 224 and the lead screw 231 are removed together.

[0189] Figures 15 - 17 is a schematic structural diagram of a printing device provided by an embodiment of the present application. As Figure 15 shown, in this example, the printing device includes a base 10, a connection structure 20 provided on the base 10, and a machine head 30 provided on the connection structure 20.

[0190] Figure 18 is a schematic structural diagram of a connection structure provided by an embodiment of the present application. As Figure 18 shown, in this connection structure 20, the fixed part 21 includes a bottom plate 212 and a horizontal slide rail 211, the movable part 22 includes a second mounting plate 221, and the driving part 23 includes a lead screw 231 and a connecting block 232.

[0191] Figure 19 is a partial structural schematic diagram of a connection structure provided by an embodiment of the present application. Figure 19 At least the movable part 22 and the lead screw 231 are omitted. Figure 20 is a schematic structural diagram of a movable part provided by an embodiment of the present application. As Figure 19 and Figure 20As shown in the figure, the connection structure 20 includes a bottom plate 212 placed on the base 10 and having second sliding grooves 212b on both sides of the top, a horizontal sliding rail 211 placed on the bottom plate 212 and located in the second sliding grooves 212b on both sides, a second mounting plate 221 placed on the horizontal sliding rails 211 on both sides and having a convex structure at the bottom, and locking parts 24 provided on both sides of the bottom plate 212 and located at the front end and the tail end of the bottom plate 212. Through the connection structure 20, the printing device can replace the printing head 30, enabling the single printing device in the past to achieve more printing functions, greatly saving the equipment purchase cost. Only by purchasing the corresponding printing head 30 can the corresponding functions be achieved.

[0192] The printing head 30 can be installed on the second mounting plate 221 by means of bolt connection, and then the second mounting plate 221 is placed on the horizontal sliding rail 211. The horizontal sliding rail 211 is located in the second sliding grooves 212b on the corresponding two sides of the bottom plate 212. By installing the bottom plate 212 on the base, the installation of the printing head 30 is achieved. The second mounting plate 221 is fastened by the locking parts 24 provided on the bottom plate 212. There are at least four locking parts 24, which are respectively installed around the bottom plate 212, and the second mounting plate 221 is fastened by the way of fastening around, effectively preventing the printing head 30 from deviating from the working position due to the vibration of the printing device.

[0193] When the printing head 30 needs to be replaced, only the locking parts 24 around need to be unlocked, then the second mounting plate 221 can be pulled out on the horizontal sliding rail 211. After replacing the required printing head 30, the second mounting plate 221 can be fixed by the locking parts 24 to complete the replacement of the printing head 30.

[0194] The bottom of the second mounting plate 221 has a convex structure, which can facilitate the positioning of the second mounting plate 221 between the two horizontal sliding rails 211, so that the second mounting plate 221 can be smoothly installed on the two horizontal sliding rails 211. The second sliding grooves 212b on the bottom plate 212 can limit the horizontal sliding rail 211. The height of the convex structure at the bottom of the second mounting plate 221 is less than the height of the horizontal sliding rail 211 protruding from the top surface of the bottom plate 212, which not only plays a role in limiting and guiding, but also avoids friction between the second mounting plate 221 and the bottom plate 212.

[0195] In this example, the driving part 23 includes a lead screw 231 and a connecting block 232. The connecting block 232 is arranged at the tail end of the bottom plate 212. The connecting block 232 is arranged at the tail end of the bottom plate 212 to enable fine adjustment of the machine head 30 on the second mounting plate 221. Exemplarily, the machine head 30 has a jack, and the lead screw 231 passes through the jack and is in clearance fit with the jack. The lead screw 231 and the machine head 30 are axially locked to each other, and the lead screw 231 can rotate relative to the machine head 30. One end of the lead screw 231 extends relative to the machine head 30, and the other end of the lead screw 231 is in threaded fit with the connecting block 232. Under the interaction between the lead screw 231 and the connecting block 232, when the lead screw 231 is rotated, the lead screw 231 can move relative to the connecting block 232, thereby driving the machine head 30 to move along the horizontal slide rail 211.

[0196] Figure 21 It is an exploded structural schematic diagram of a locking part provided by an embodiment of the present application. As Figure 21 shown, the locking part 24 includes a pressing block 241, and the pressing block 241 is movably connected to the fixed part 21. The pressing block 241 is used to press the movable part 22.

[0197] Figure 22 It is a partial structural schematic diagram of a connection structure provided by an embodiment of the present application. As Figure 21 and Figure 22 shown, in this example, the locking part 24 further includes a fixed seat 242 arranged on the bottom plate 212, a fastening screw 243 arranged on the fixed seat 242 and passing through the pressing block 241, and a third handle 244 arranged on the fastening screw 243. One side of the pressing block 241 has a boss 2411. The locking part 24 is installed on the bottom plate 212 through the fixed seat 242, and the pressing block 241 is installed on the fixed seat 242 through the fastening screw 243. The positive projection of the boss 2411 on the pressing block 241 is at least partially located inside the second mounting plate 221. When fixing the second mounting plate 221, the fastening screw 243 is rotated through the third handle 244 to make the boss 2411 on the pressing block 241 contact the second mounting plate 221, and then the second mounting plate 221 is fastened to the bottom plate 212, that is, the installation of the machine head 30 is completed. When replacing the machine head 30, the pressing block 241 is released by rotating the fastening screw 243 through the third handle 244 to make the boss 2411 disengage from the second mounting plate 221, so that the second mounting plate 221 and the machine head 30 can be pulled out from the horizontal slide rail 211. After replacing the machine head 30, the machine head 30 and the second mounting plate 221 can be installed on the horizontal slide rail 211 again.

[0198] As Figure 21As shown, the fixed seat 242 is in an inverted L shape and has an assembly groove 242a at the top. The bottom of the pressing block 241 has a protrusion 2412 that mates with the assembly groove 242a. The fixed seat 242 is made in an L shape to make the fixed seat 242 more stable during installation and prevent the fixed seat 242 from loosening. The assembly groove 242a is provided at the top of the fixed seat 242 to cooperate with the protrusion 2412 at the bottom of the pressing block 241, and it is convenient to position the pressing block 241 through the cooperation of the assembly groove 242a and the protrusion 2412.

[0199] As an example, the printing device may further include a positioning pin 261 and a scale bar 262. The positioning pin 261 may be located at the edge of the second mounting plate 221 and connected to the second mounting plate 221. The scale bar 262 may be located on the bottom plate 212, and the scale bar 262 is arranged along the extension direction of the horizontal slide rail 211. The positioning pin 261 points to the scale bar 262. During the process of adjusting the second mounting plate 221 along the horizontal slide rail 211, the positioning pin 261 moves relative to the scale bar 262, and the position of the second mounting plate 221 can be accurately adjusted according to the change in the position indicated by the positioning pin 261 on the scale bar 262, improving the installation accuracy of the machine head 30.

[0200] In this example, a positioning pin 261 with the pointer direction facing the bottom plate 212 is provided at the front end of one side of the second mounting plate 221, and a scale bar 262 is provided at the position of the bottom plate 212 corresponding to the positioning pin 261. The positioning pin 261 is provided on the second mounting plate 221 and the scale bar 262 is provided on the bottom plate 212 to play a positioning role when installing the second mounting plate 221, and at the same time, it also plays a role in facilitating the installation of the machine head 30, so as to more accurately position and install the machine head 30.

[0201] A plurality of bottom plate fixing holes 212a for fixing the bottom plate 212 to the base 10 are provided on the bottom plate 212. A plurality of bolt holes 221a for fixing the machine head 30 are provided on the second mounting plate 221. The bottom plate fixing holes 212a are for conveniently connecting the bottom plate 212 to the base 10 through bolts. The bolt holes 221a are for conveniently connecting the machine heads 30 with different functions to the second mounting plate 221, and then installing them on the base 10, enabling a single printing device to achieve more printing functions and meeting different printing requirements with one device.

[0202] The printing device further includes a plurality of height adjusting feet 11 provided at the bottom of the base 10. The height adjusting feet 11 are provided on the base 10 to conveniently adjust the height of the entire printing device, so as to better cooperate with other printing devices for use. The height adjusting feet 11 can also be used to adjust the levelness of the printing device to make the printing device reach the best use state.

[0203] The printing device further includes an adapter plate 12 disposed on the base 10 for connecting to other printing devices. The adapter plate 12 is provided on the base 10 to facilitate connection with other printing devices, enabling multiple printing devices to be connected as a single unit.

[0204] Exemplarily, the printing head 30 includes a flexographic printing head or a die-cutting head. For example Figures 15 - 17 In the illustrated printing device, the printing head 30 is a die-cutting head. Figure 23 and Figure 24 FIG. is a schematic structural diagram of a printing device provided by an embodiment of the present application. As Figure 23 and Figure 24 shown, in this example, the printing head 30 is a flexographic printing head.

[0205] By connecting different process heads to the base 10, such a printing device achieves the effect of implementing different processes on the same base 10, thereby reducing the cost of purchasing multiple printing devices, reducing the floor space cost of multiple printing devices, and reducing the labor cost of multiple operators. Additionally, such a printing device has a simple structure and low cost, and can satisfy the interchangeability of a flexographic printing head and a die-cutting head.

[0206] Figure 25 FIG. is a schematic structural diagram of a printing device provided by an embodiment of the present application. As Figure 25 shown, in this example, a printing head 30 is disposed on the base 10, and the printing head 30 is an inkjet printing head. An operation table 8 is further disposed on the base 10, and an operation computer 9 for controlling the printing device is disposed on the operation table 8.

[0207] The plurality of functional rollers 40 may include a fixed traction roller 41, a cooling roller 42, a plurality of paper feeding rollers 43, and a fixed laminating roller 44, where the cooling roller 42 may be a water-cooled roller. The paper feeding rollers 43 are for defining the paper feeding direction of the printed product 7 and ensuring sufficient paper feeding space for the printed product 7.

[0208] The printing device includes a traction assembly and a laminating assembly. As Figure 25 shown, two brackets 113 are disposed on the base 10, with one bracket 113 arranged close to the fixed traction roller 41 and the other bracket 113 arranged close to the fixed laminating roller 44.

[0209] The functional member 1131 disposed on the bracket 113 arranged close to the fixed traction roller 41 is a movable traction roller; the functional member 1131 disposed on the bracket 113 arranged close to the fixed laminating roller 44 is a movable laminating roller.

[0210] The traction assembly includes a fixed traction roller 41 and a movable traction roller, and the laminating assembly includes a fixed laminating roller 44 and a movable laminating roller.

[0211] As Figure 25As shown, the printing device further includes a pre-curing unit 61 and a final-curing unit 62, wherein the pre-curing unit 61 is arranged adjacent to the fixed film laminating roller 44, and the final-curing unit 62 is arranged adjacent to the cooling roller 42.

[0212] That is, the printing device includes a base 10, an inkjet head disposed on the base 10, a traction assembly disposed on the base 10, a film laminating assembly disposed on the base 10, a pre-curing unit 61 disposed on the base 10, and a final-curing unit 62 disposed on the base 10.

[0213] During operation, the printed product 7 is introduced into the printing device through the traction assembly, sprayed by the inkjet head. After spraying, the printed product 7 is pre-cured by the pre-curing unit 61. After pre-curing, it is film laminated by the film laminating assembly. After film lamination, it is finally cured by the final-curing unit 62. After completion, the printed product 7 is exported. The pre-curing unit 61 and the final-curing unit 62 can be curing units used in related art for printing devices as long as they can achieve their functions.

[0214] The cooling roller 42 is located above the final-curing unit 62. During operation, after the printed product 7 is film laminated, it passes through the cooling roller 42 and the final-curing unit 62 simultaneously for cooling and final curing. The cooling roller 42 is used for some special materials. For example, heat shrinkable films and other materials that are intolerant to high temperatures require the use of the cooling roller 42 for cooling. If it is paper or heat-resistant film materials, the cooling roller 42 may not be needed. Therefore, the cooling roller 42 can be selectively installed according to different needs.

[0215] The inkjet head includes at least one inkjet cartridge (not shown in the figure) disposed on the base 10, and nozzles disposed on the inkjet cartridge, connecting the inkjet cartridge, with the nozzles facing the printed product 7 and the number of nozzles being the same as the number of inkjet cartridges. Different materials such as glue, ink, varnish, etc. are placed in the inkjet head through the inkjet cartridges. Corresponding nozzles are provided at the bottom of the inkjet cartridges. The specific number of inkjet cartridges is installed according to different requirements. These nozzles are all controlled by an operation computer 9. When in use, the operation computer 9 controls different nozzles to work according to different printing requirements to achieve the required printing requirements. The inkjet head can be an inkjet head in related art as long as it can achieve the required functions.

[0216] The traction assembly includes a fixed traction roller 41 disposed on the base 10, a bracket 113 hinged to the base 10, a movable traction roller disposed on the bracket 113 via a shaft rod and tangent to the fixed traction roller 41 during operation, and an adjusting member 1132 disposed on the base 10 and connected to the bracket 113 by a telescopic rod, which is a traction cylinder here. The traction assembly is responsible for pulling the printed product 7 into the printing equipment. By controlling the pulling force of the movable traction roller through the traction cylinder, the traction assembly can be used to pull various printed products 7 without damaging the printed product 7 or having insufficient traction due to excessive or insufficient pulling force.

[0217] The film laminating assembly includes a fixed film laminating roller 44 disposed on the base 10, a bracket 113 hinged to the base 10, a movable film laminating roller disposed on the bracket 113 via a shaft rod and tangent to the fixed film laminating roller 44 during operation, and an adjusting member 1132 disposed on the base 10 and connected to the bracket 113 by a telescopic rod, such as a film laminating cylinder. The film laminating assembly controls whether to perform film lamination through the film laminating cylinder. When film lamination is not required, the film laminating cylinder controls the movable film laminating roller not to participate in the work. Moreover, the film laminating assembly can also control the film laminating force through the film laminating cylinder, enabling the film laminating assembly to perform film lamination work with different requirements.

[0218] Exemplarily, both the traction cylinder and the film laminating cylinder can be gas-driven telescopic cylinders. In some examples, the adjusting member 1132 can also be an electric telescopic rod.
