[0027] Referring to the accompanying drawings, which are examples of this embodiment, the functional component station switching mechanism of the printing press includes a longitudinal track 1, a longitudinal movable frame 2, a transverse connecting rail 3, a transverse movable frame 5, and a transverse guide component 4. The longitudinal track 1 is connected to the rear side of the printing unit of the printing press. The longitudinal track is located behind the rear wall panel of the printing unit of the printing press, and the front wall panel is located in front of the rear wall panel. The rear side refers to Figure 3 In the direction to the right, the front side refers to Figure 3 The left direction in the middle, in this embodiment, the longitudinal direction refers to the direction in which the various printing units of the printing press are arranged. The longitudinal movable frame 2 is configured on the longitudinal track 1, and the longitudinal movable frame 2 can be moved back and forth on and along the longitudinal track 1 to adjust the switching position, and a corresponding slider 26 can be configured for cooperative connection. The transverse rail 3 is installed on the longitudinal movable frame 2, and the transverse rail 3 will move back and forth with the longitudinal movable frame 2 to adjust the switching position, and the transverse and longitudinal directions are orthogonal. The transverse guide component 4 is connected and installed on the transverse movable frame 5, and the transverse guide component 4 and the transverse movable frame 5 will move laterally synchronously, and the transverse guide component 4 is cooperatively connected with the transverse rail 3. When the transverse guide component 4 is located on the transverse rail 3, the transverse guide component 4 will move back and forth laterally along the transverse rail 3. In the figure, the transverse rail 3 has a groove rail, and the transverse guide component 4 adopts a guide wheel, which is configured on the groove rail. Of course, other methods can also be used, such as a linear slide rail and a slider 26; the guide wheel is installed on the side plate 20, and a guide plate 29 can be added to the outer side of the side plate 20. The guide plate 29 has a raised guide strip. The side of the transverse rail 3 also has a guide groove. When the guide strip is retracted laterally, it can be engaged and matched in the guide groove. Lateral retraction refers to Figure 3 The direction of movement is to the right, and the structural stability is better.

[0028] In this embodiment, the transverse movable frame 5 is connected and installed for the corresponding functional components of the printing machine (not shown in the figure, such as the hot stamping device, the inkjet device, the screen device, the die-cutting device or the slitting device, etc.). For example, when the functional component is a hot stamping device, the functional component is installed on the transverse movable frame 5. When the functional component (such as the hot stamping device) needs to be used in different printing units, it can be switched through the functional component station switching mechanism of the printing machine. When working, the longitudinal movable frame 2 is first adjusted and moved along the longitudinal track 1 to the rear side of the printing unit where the functional component needs to be used, and then the transverse movable frame 5 on the longitudinal movable frame 2 is moved forward transversely along the transverse connecting track 3, that is, transverse forward refers to Figure 3In the leftward running direction, the transverse movable frame 5 is moved transversely to the upper part of the printing unit to be used, and the functional components installed on the transverse movable frame 5 can be used for printing. When switching, the transverse movable frame 5 first retracts laterally, causing the transverse guide component 4 to retract along the transverse connecting rail 3. After retraction, it can be adjusted and moved with the longitudinal movable frame 2 to the printing unit where the functional components are needed. The functional component station switching mechanism of the printing press is easy to use and can move and switch installed functional components between different printing units, which is more practical.

[0029] Based on the embodiment, the functional component station switching mechanism of the printing press further includes an auxiliary support member 6 (such as a support plate or support rod) to provide auxiliary support for the lateral movable frame 5 during lateral movement, ensuring more stable lateral movement. The auxiliary support member 6 is connected between the front wall panel 13 and the rear wall panel 14 of the printing unit, and cooperates with the auxiliary support member 6 to support the lateral movable frame 5 during lateral movement.

[0030] Based on the embodiment, further optimization is performed to achieve derailment and separation. The functional component station switching mechanism of the printing press also includes a connecting cross rail 7, a cross rail guide seat 8, a first connecting component 9, a second connecting component 10, a third connecting component 11 and a fourth connecting component 12. The connecting cross rail 7 is arranged on the cross rail guide seat 8, and the connecting cross rail 7 and the cross rail guide seat 8 can move back and forth relative to each other laterally. The cross rail guide seat 8 is installed on the transverse moving frame 5, and the cross rail guide seat 8 moves laterally synchronously with the transverse moving frame 5. The first connecting component 9 is installed on the connecting cross rail 7, and the first connecting component 9 is located at the front of the connecting cross rail 7. The front refers to Figure 3 The middle is the left end; the first connecting member 9 moves back and forth horizontally along the connecting rail 7. The second connecting member 10 is installed on the front wall panel 13 of the printing unit, and the second connecting member 10 is assembled and docked with the first connecting member 9 in a horizontal manner; when the first connecting member 9 moves horizontally along the connecting rail 7, the horizontal advance refers to Figure 3 In the direction of left movement, the first connecting part 9 will be connected with the second connecting part 10 to realize horizontal assembly and docking; when the connecting rail 7 moves back horizontally, the first connecting part 9 and the second connecting part 10 are separated horizontally. The third connecting part 11 is installed on the connecting rail 7. The third connecting part 11 is located at the rear of the connecting rail 7. The rear refers to Figure 3 The middle portion is the right end. The third connecting component 11 moves back and forth laterally with the connecting rail 7. The fourth connecting component 12 is mounted on the rear wall panel 14 of the printing unit. The fourth connecting component 12 and the third connecting component 11 are assembled and docked laterally. When the third connecting component 11 moves laterally with the connecting rail 7, it mates with the fourth connecting component 12 to achieve transverse assembly and docking. When the connecting rail 7 retracts laterally, the third connecting component 11 and the fourth connecting component 12 separate laterally. The connecting rail 7 can be a linear slide (e.g., a linear cylindrical slide).

[0031] The optimized structure is that before the transverse guide component 4 moves laterally with the transverse moving frame 5, a connecting transverse rail 7 for support can be arranged between the front wall panel 13 and the rear wall panel 14, and the connecting transverse rail 7 is extended forward and laterally from the transverse moving frame 5 and mounted between the front wall panel 13 and the rear wall panel 14; when the transverse guide component 4 and the transverse moving frame 5 move laterally, the transverse guide component 4 first moves on the transverse connecting rail 3, and then the transverse guide component 4 derails and separates from the transverse connecting rail 3, and the transverse rail guide seat 8 on the transverse moving frame 5 remains in cooperation with the connecting transverse rail 7. In addition, the connecting transverse rail 7 is previously extended and arranged on the front wall panel 13 and the rear wall panel 14, so that the front wall panel 13 and the rear wall panel 14 can support the transverse rail guide seat 8 and the transverse moving frame 5 through the connecting transverse rail 7, supporting them (the transverse rail guide seat 8 and the transverse moving frame 5) so that they can continue to move laterally after the transverse guide component 4 is derailed and separated from the transverse connecting rail 3. After the transverse guide component 4 is derailed and separated from the transverse connecting rail 3, the longitudinal movable frame 2 no longer supports the corresponding transverse movable frame 5, and the longitudinal movable frame 2 can be moved unloaded to other printing units, and other transverse movable frames 5 can be moved to the unloaded longitudinal movable frame 2, thereby realizing the replacement of different transverse movable frames 5 in sequence with each other. In the future, the longitudinal order of the functional components installed on the transverse movable frame 5 can also be replaced. For example, the functional component of the hot stamping device is arranged at the back, and the functional component of the inkjet device is arranged at the front. After replacement, the replacement of the sequential position can be realized, which is more practical. Moreover, the connecting transverse rail 7 and the transverse rail guide seat 8 can be set in a one-to-one correspondence with the transverse movable frame 5, and one transverse movable frame 5 is correspondingly provided with a set of connecting transverse rails 7 and transverse rail guide seat 8.

[0032] Based on the embodiment, further optimization is performed. The first connecting component 9 and the second connecting component 10 respectively use matching docking plates and docking ports, that is, one uses a docking plate and the other uses a docking port. In addition, when the first connecting component 9 uses a docking plate, when the first connecting component 9 extends along the connecting rail 7, the first connecting component 9 can also be supported by the auxiliary support component 6. The third connecting component 11 and the fourth connecting component 12 respectively use matching docking pins and docking holes, that is, one uses a docking pin and the other uses a docking hole. Alternatively, the first connecting component 9 and the second connecting component 10 respectively use matching docking pins and docking holes, that is, one uses a docking pin and the other uses a docking hole. The third connecting component 11 and the fourth connecting component 12 respectively use matching docking plates and docking ports, that is, one uses a docking plate and the other uses a docking port. When the docking plates are placed in the docking ports, assembly docking is achieved, and when they are separated horizontally, the assembly docking relationship is released. When the docking pins are inserted into the docking holes, assembly docking is achieved, and when they are separated horizontally, the assembly docking relationship is released. This optimized assembly docking structure is easy to connect and has relatively accurate positioning. One end of the connecting cross rail 7 can be precisely positioned, while the other end does not need to be precisely positioned. This is more practical and simpler to process and assemble. Positioning is more accurate when using docking holes and docking pins. The second connecting component 10 in the figure uses a docking port. In this embodiment, the docking port is set on the mounting block 27, and the mounting block 27 is then set on the front wall panel 13; the third connecting component 11 uses a docking pin, which is installed on the connecting rail through the docking pin seat 15. The fourth connecting component 12 uses a docking hole, which is located on the mounting plate 28, and is then set on the rear wall panel 14 through the mounting plate.

[0033] Based on the embodiment, further optimization is performed, and the transverse movable frame 5 is connected with a transverse adjustment device to adjust the transverse position of the transverse movable frame 5 so that its position is more accurate. After the transverse movable frame 5 moves forward laterally to its position, the position can be further adjusted by the transverse adjustment device. The transverse adjustment device includes a nut 16, a screw rod 17 and a screw rod rotation support seat 18. The nut 16 is installed on the transverse movable frame 5, and a nut seat can be configured on the transverse movable frame 5 for installing the nut 16 so that the nut 16 and the transverse movable frame 5 can move laterally synchronously. The screw rod 17 is connected to the nut 16 to realize the transmission of the screw rod 17 and the nut 16. The screw rod 17 is installed and connected to the screw rod rotation support seat 18, and the screw rod 17 is connected to the screw rod rotation support seat 18. The screw rod 17 and the screw rod rotation support seat 18 can rotate relative to each other. When the screw rod rotation support seat 18 is fixedly supported, the screw rod 17 is supported by the screw rod rotation support seat 18 to rotate. The screw rotation support seat 18 has a matching portion for fixed support connection, and the screw rotation support seat 18 is fixedly supported by the matching portion, for example, the matching portion is connected to the fixed support portion, and the fixed support portion can be the front wall panel 13 or the rear wall panel 14 or a component connected to the front wall panel 13 or the rear wall panel 14; the matching portion of the support seat in the figure is connected and matched with the first connecting component 9 (as the fixed support portion). When the first connecting component 9 on the connecting rail 7 is horizontally assembled and docked with the second connecting component 10 on the front wall panel 13, the position of the first connecting component 9 will be relatively fixed, and the matching portion of the support seat is connected to the first connecting component 9. The first connecting component 9 will fixedly support the support seat. Specifically, there is a notch on the first connecting component 9, and the matching portion of the support seat has a card slot (with card plates 19 on both sides). When the support seat is located in the notch, the support seat is rotated to clamp the card plates on both sides of the card slot on both sides of the notch.

[0034] In a further improvement based on the embodiment, the longitudinal movable frame 2 is equipped with a positioning device. This device facilitates the longitudinal movable frame 2 to be positioned accurately behind the corresponding printing unit during longitudinal movement, making it more convenient to use. The positioning device includes a lifting positioning pin, a return spring (not shown), and a positioning seat 21. The lifting positioning pin is connected to the longitudinal movable frame 2, and the return spring is located between the lifting positioning pin and the longitudinal movable frame 2. The lifting positioning pin can be raised and lowered relative to the longitudinal movable frame 2, and the return spring resets the lifting positioning pin downward. The positioning seat 21 is fixedly arranged and located below the lifting positioning pin. The positioning seat 21 has a positioning opening 22 and an introduction surface 23. The positioning opening 22 matches the lifting positioning pin. When the lifting positioning pin is inserted into the positioning opening 22, it plays a positioning role. The introduction surface 23 is located on both sides of the positioning opening 22. The introduction surface 23 corresponds to the lifting positioning pin. When the lifting positioning pin moves with the longitudinal movable frame 2, the lifting positioning pin will rise along the introduction surface 23 until the lifting positioning pin moves to the positioning opening 22. Under the action of the return spring, the lifting positioning pin descends and is inserted into the positioning opening 22 to achieve positioning. The longitudinal movable frame 2 moves to the rear side of the corresponding printing unit, and the transverse movable frame 5 can be moved transversely, which makes it more convenient to configure the positioning device in place. In addition, a rotating rod with a toggle fork can be configured on the longitudinal movable frame 2. By rotating, the toggle fork can be driven back and forth. The toggle fork can cooperate with the connecting block on the lifting positioning pin, so that the lifting positioning pin inserted into the positioning opening 22 can be moved upward.

[0035] In a further optimization based on the embodiment, a mounting bracket 24 is further provided on the transverse movable frame 5. Functional components are arranged on the transverse movable frame 5 via the mounting bracket 24. Functional components are mounted on the mounting bracket 24, which is then mounted on the transverse movable frame 5. The mounting bracket 24 can be directly mounted on the transverse movable frame 5 via a connecting component. Further optimization can be performed by providing a vertical rotation axis 25 between the mounting bracket 24 and the transverse movable frame 5, so that the mounting bracket 24 can rotate on the transverse movable frame 5. This makes the spatial layout more reasonable and allows for rotation to change the length and width, making it easier to move, especially when the functional components are relatively wide.

[0036] In addition to the above-mentioned derailment separation method, another derailment method can be adopted. The functional component station switching mechanism of the printing press also includes a transverse track and a transverse guide element; the transverse track is configured on the front wall panel 13 and / or the rear wall panel 14 of the printing unit; the transverse guide element is connected to the transverse movable frame 5, and the transverse movable frame 5 moves laterally synchronously with the transverse guide element, and the transverse guide element cooperates with the transverse track. When the transverse movable frame 5 moves with the longitudinal movable frame 2 to the rear side of the printing unit where the functional component is required, the transverse movable frame 5 can move laterally; when the transverse movable frame 5 moves laterally, the transverse guide element of the transverse movable frame 5 will dock with the transverse track, and the transverse movable frame 5 will transfer from the transverse connecting track 3 of the longitudinal movable frame 2 to the transverse track, achieving derailment and separation, so that the longitudinal movable frame 2 can move independently; when the transverse movable frame 5 moves laterally, the transverse guide element of the transverse movable frame 5 will retract laterally from the transverse track, the transverse guide element derails and separates from the transverse track, and the transverse movable frame 5 retracts laterally to the transverse connecting track 3 of the longitudinal movable frame 2. The transverse guide element and the transverse guide component 4 use the same or different components, that is, the transverse guide element and the transverse guide component 4; if the same components are used, they can cooperate with both the transverse connecting rail 3 and the transverse track; if different components are used, they can cooperate with the transverse connecting rail 3 and the transverse track respectively.

[0037] In a further optimization based on the embodiment, the transverse guide member 4 and the transverse connecting rail 3 are connected by a docking fit to facilitate derailment. This docking fit allows the transverse guide member 4 to move on the transverse connecting rail 3 when on the longitudinal movable frame 2. When the transverse movable frame 5 moves laterally from the longitudinal movable frame 2 and derails, the transverse guide member 4 separates from the transverse connecting rail 3. When the transverse movable frame 5 retracts laterally, the transverse guide member 4 can re-docking with the transverse connecting rail 3 and move on the transverse connecting rail 3.
