[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] See the appendix Figure 1, in the printing press of the unit type in this embodiment, it includes a front mechanism 1, a printing unit 2, and a rear mechanism 3, which can supply the continuous web substrate to select various ways to replace printing. Among them, the printing unit 2 includes at least two unit cells 20, and multiple unit cells 20 can be set according to requirements. The unit cells 20 are arranged in sequence from front to back. The printing unit 2 is arranged between the front mechanism 1 and the rear mechanism 3, that is, multiple unit cells 20 are arranged between the front mechanism 1 and the rear mechanism 3.

[0037] Among them, the front mechanism 1 includes a front traction device 10, and the front traction device 10 can be used to cooperate with the traction of the substrate. The front traction device 10 includes a front traction roller 101.

[0038] Among them, the rear mechanism 3 includes a rear traction device 30, and the rear traction device 30 can be used to cooperate with the traction of the substrate. The rear traction device 30 includes a rear traction roller 301.

[0039] Each unit cell 20 respectively includes a printing mechanism 22. The printing mechanism 22 includes a plate cylinder 221, a transfer roller 222, and a substrate bottom roller 223. The printing mechanism 22 can be used to print the substrate. The printing mechanism 22 includes a plate cylinder 221, a transfer roller 222, and a substrate bottom roller 223. Among them, the transfer roller 222 and the substrate bottom roller 223 are used for the input and output of the substrate, which is relatively mature. The rear traction device 30 is also connected to a centralized curing mechanism 4, and the centralized curing mechanism 4 can cooperate to perform corresponding curing on the printed substrate according to requirements.

[0040] In this unit type of printing press, the substrate can be routed and wound according to requirements, and has a centralized curing non-return continuous printing method. Its structure is relatively simple, and the operation is convenient, which can meet the printing requirements of this type of substrate.

[0041] The following optimizations or further explanations can be made respectively on the above basic embodiments.

[0042] For example, in Embodiment 1, see the appendix Figure 1, in the basic embodiment, the web-fed printing press has a centralized curing non-retreating continuous printing method. When using the centralized curing non-retreating continuous printing method, the substrate does not retreat during the entire normal printing process. The substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 in the printing unit 2, so as to connect and wind the substrate output and input; between the printing unit 20 and another printing unit 20 at the rear, the substrate output end of the printing mechanism 22 of the printing unit 20 is connected to the substrate input end of the printing mechanism 22 of another printing unit 20 at the rear, so as to connect and wind the substrate output and input; the substrate between the two printing mechanisms 22 can be directly pulled through, such as directly laid out horizontally; the substrate output end of the rear printing mechanism 22 in the printing unit 2 is connected to the substrate input end of the rear traction device 30, so as to connect and wind the substrate output and input, and the centralized curing mechanism 4 is in an online connection state. The centralized curing mechanism 4 can cooperate to perform corresponding curing on the printed substrate. The substrate can pass through the centralized curing mechanism 4, so that the centralized curing mechanism 4 can perform centralized curing treatment on the substrate during operation. Generally, the front traction device 25 of the unit and the rear traction device 26 of the unit maintain the same linear speed to traction the substrate.

[0043] Embodiment 2, see the appendix Figure 2, on the basis of the basic embodiment, the structure of the printing machine can be further optimized. Each unit 20 of the printing machine further includes a unit curing mechanism 23, that is, each unit is additionally provided with a unit curing mechanism. The unit curing mechanism 23 is arranged behind the printing mechanism 22, so that the printing machine has a shared structure when the printing methods increase, and the use cost is relatively low. For example, it has a centralized curing non-retracting continuous printing method. When using the centralized curing non-retracting continuous printing method: the substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 in the printing unit 2; between the unit 20 and another unit 20 at the rear, the substrate output end of the printing mechanism 22 of the unit 20 is connected to the substrate input end of the printing mechanism 22 of another unit 20 at the rear; the substrate output end of the printing mechanism 22 at the rear in the printing unit 2 is connected to the substrate input end of the rear traction device 30; the unit curing mechanism 23 is in a connection avoidance state, and the centralized curing mechanism 4 is in an online connection state; the centralized curing non-retracting continuous printing method has been described above and will not be elaborated here. Another example is that it has a grouped curing non-retracting continuous printing method. When using the grouped curing non-retracting continuous printing method: the substrate does not retract during the entire normal printing process, and each unit can group-cure the printed substrate by the unit curing mechanism 23. The substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 in the printing unit 2 for the connection and winding layout of the substrate output and input; within each unit 20, the substrate output end of the printing mechanism 22 is connected to the substrate input end of the unit curing mechanism 23 for the connection and winding layout of the substrate output and input; between the unit 20 and another unit 20 at the rear, the substrate output end of the unit curing mechanism 23 of the unit 20 is connected to the substrate input end of the printing mechanism 22 of another unit 20 at the rear for the connection and winding layout of the substrate output and input; the substrate output end of the unit curing mechanism 23 of the unit 20 at the rear in the printing unit 2 is connected to the substrate input end of the rear traction device 30 for the connection and winding layout of the substrate output and input; the unit curing mechanism 23 is in a connected state, and the centralized curing mechanism 4 is in an idle state. Each unit can group-cure the printed substrate by the unit curing mechanism 23, and the centralized curing mechanism 4 does not need to be additionally centralized and cured and does not need to operate.For another example, it also has a double-curing non-retracting continuous printing method. When using the double-curing non-retracting continuous printing method: the substrate does not retract during the entire normal printing process, and the substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 in the printing unit 2; within each unit 20, the substrate output end of the printing mechanism 22 is connected to the substrate input end of the unit curing mechanism 23; between the unit 20 and another unit 20 at the rear, the substrate output end of the unit curing mechanism 23 of the unit 20 is connected to the substrate input end of the printing mechanism 22 of another unit 20 at the rear; the substrate output end of the unit curing mechanism 23 of the last unit 20 in the printing unit 2 is connected to the substrate input end of the rear traction device 30; the unit curing mechanism 23 is in a connected state, and the centralized curing mechanism 4 is in an on-line connected state. In each unit, the printed substrate can be grouped and cured by the unit curing mechanism 23. At the same time, the centralized curing mechanism 4 can also additionally and centrally cure the printed substrate. Double curing can better cure the substrate with a relatively thick printing ink thickness.

[0044] Embodiment 3, see the appendix Figure 3, or other structures of the printing press can be optimized on the basis of the basic embodiment, the front mechanism 1 also includes a front floating device 11; the front floating device 11 includes a front floating roller 110, and the front floating roller 110 is connected to the front floating drive motor; the front floating drive motor cooperates to drive the front floating roller 110 to float, such as the floating operation of the left and right movements in the figure, the front floating device 11 can be used to cooperate with the floating effect on the substrate, such as the front floating roller 110 can cooperate with the substrate through floating operation, and the front traction device 10 is arranged before the front floating device 11; that is, when the substrate is wound, it can first pass through the front traction device 10 and then pass through the front floating device 11 to arrange the substrate. The rear floating device 31 can be used to cooperate with the floating effect on the substrate, and the rear floating device 31 includes a rear floating roller 311, and the rear floating roller 311 can cooperate with the substrate through floating operation. The rear floating roller 311 is connected to the rear floating drive motor by transmission, and the rear floating drive motor cooperates to drive the rear floating roller 311 to perform floating operation, such as the floating operation of left and right movement in the figure. The rear traction device 30 is arranged behind the rear floating device 31, that is, when the substrate is wound, it can first pass through the rear floating device 31 and then pass through the rear traction device 30 to arrange the substrate. The printing unit 2 is also provided with a unit curing component 27, and the rear side of each unit unit 20 is respectively configured with a unit curing component 27; each unit unit 20 is respectively shifted and adjusted forward and backward, and the forward and backward movement position is used for phase adjustment. There is no need to move the position forward and backward during transportation. The entire unit unit 20 can be set on the unit frame wall panel, and the unit frame wall panel moves forward and backward on the guide rail of the base (left and right direction in the figure). In addition, the centralized curing mechanism 4 is not configured, that is, it can be not configured when leaving the factory or in an idle state. Even if it is configured, it does not need centralized curing operation, and no additional curing is required.For example, it has an intermittent overall backward printing method. When using the intermittent overall backward printing method: the printing substrate intermittently moves backward as a whole during the entire normal printing process. The printing substrate output end of the front traction device 10 is connected to the printing substrate input end of the front floating device 11. The printing substrate output end of the front floating device 11 is connected to the printing substrate input end of the printing mechanism 22 of the front unit 20 in the printing unit 2. The printing substrate output end of the printing mechanism 22 of the unit 20 is connected to the printing substrate input end of the rear unit curing assembly 27. The printing output end of the unit curing assembly 27 is connected to the printing substrate input end of the printing mechanism 22 of another rear unit 20. The printing substrate output end of the rear unit curing assembly 27 in the printing unit 2 is connected to the printing substrate input end of the rear floating device 31. The printing substrate output end of the rear floating device 31 is connected to the printing substrate input end of the rear traction device 30. The front and rear displacement adjustment of the unit 20 is used for phase adjustment. The front floating device 11 and the rear floating device 31 are in a connected floating operation state, and are in the connected floating operation state so as to cooperate with the floating operation to control the intermittent backward movement of the printing substrate as a whole and the return after the backward movement. For another example, it has a continuous non-backward printing method. When using the continuous non-backward printing method: the printing substrate does not move backward continuously during the entire normal printing process. The printing substrate output end of the front traction device 10 is connected to the printing substrate input end of the front printing mechanism 22 in the printing unit 2. Between the unit 20 and another rear unit 20, the printing substrate output end of the printing mechanism 22 of the unit 20 is connected to the printing substrate input end of the printing mechanism 22 of another rear unit 20. The printing substrate output end of the printing mechanism 22 at the rear of the printing unit 2 is connected to the printing substrate input end of the rear traction device 30. The front floating device 11 and the rear floating device 31 are in a connected non-floating operation state, that is, the printing substrate passes through the front floating device 11 and the rear floating device 31, but there is no need for corresponding floating operation, and the unit curing assembly 27 is in a connected curing operation state, that is, the printing substrate passes through it and is in a curing operation. Or, the front floating device 11 and the rear floating device 31 are in a state of avoiding material receiving, that is, the printing substrate does not wind through them, and at least one of the unit curing assembly 27 and the centralized curing mechanism 4 is in a connected curing operation state.

The unit front floating roller 242 and the unit rear floating roller 243 will float together with the unit floating seat 241; the unit floating seat 241 is in transmission connection with the unit floating drive motor, and the unit floating drive motor cooperates to drive the unit floating seat 241 to float, such as floating left and right as shown in the figure, so as to connect the printing material in the corresponding unit 20 to float, cooperate with the printing material in the corresponding unit 20 to retreat, and then float back to the original position after the retreat is completed; the centralized curing mechanism 4 is in a configured state or an unconfigured state. For example, it has a grouped curing and non-retreating continuous printing method. When the grouped curing and non-retreating continuous printing method is adopted: after the printing material is printed in different units 20, it is directly cured by the unit curing mechanism 23 in the corresponding unit 20. The front floating device 11 is in the receiving and non-floating operating state or in the state of avoiding receiving, the rear floating device 31 is in the receiving and non-floating operating state or in the state of avoiding receiving, and the unit floating mechanism 24 is in the receiving and non-floating operating state or in the state of avoiding receiving; in the present invention, the receiving and floating operating state means that the printing material can be connected and arranged to pass through, and it needs to float during the printing process; the receiving and non-floating operating state means that the printing material can be connected and arranged to pass through, but it does not need to float during the printing process; the state of avoiding receiving means that the printing material does not pass through it by winding, which will not be elaborated here.In this printing method, the substrate output end of the front traction device 10 is connected to the substrate input end of the front printing mechanism 22 in the printing unit 2; within each unit 20, the substrate output end of the printing mechanism 22 is connected to the substrate input end of the unit curing mechanism 23; between the unit 20 and another unit 20 at the rear, the substrate output end of the unit curing mechanism 23 of the unit 20 is connected to the substrate input end of the printing mechanism 22 of another unit 20 at the rear; the substrate output end of the unit curing mechanism 23 of the last unit 20 in the printing unit 2 is connected to the substrate input end of the rear traction device 30. For another example, it has a grouped curing intermittent integral backward printing method. When using the grouped curing intermittent integral backward printing method: curing is directly carried out by the unit curing mechanism 23 in the corresponding unit 20 to achieve grouped curing, and the substrate intermittently moves backward integrally during the entire normal printing process, which can eliminate the blank gaps on the substrate. The intermittent integral backward movement will be controlled by the front floating device 11 and the rear floating device 31 through floating cooperation.
