Description

Technical Field

[0001] The present application relates to the technical field of printing presses, and in particular to an imprinting device of a printing press. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product identical to the printing plate.

[0003] The embossing device of a printing press is a crucial part of the printing process. It is mainly responsible for transferring ink from the printing plate to the printing material to form the required graphic information. The embossing device of a printing press is mainly composed of the plate cylinder, the impression cylinder (or rubber cylinder) and the auxiliary equipment between them. When the plate cylinder and the impression cylinder (or rubber cylinder) exert sufficient pressure on the printing material, the ink is squeezed out of the printing plate and adheres to the surface of the printing material to form graphic information.

[0004] In the existing printing press embossing device, the plate cylinder and the impression cylinder are usually installed inside the embossing device. Since the plate cylinder and the impression cylinder are both parts that are easily worn out in the embossing device, in order to ensure the embossing quality of the printing press, the plate cylinder and the impression cylinder need to be replaced and maintained regularly. However, in the existing printing press embossing device, the replacement process of the plate cylinder and the impression cylinder is relatively troublesome. Summary of the invention

[0005] The present application provides an imprinting device for a printing press, which can facilitate staff to replace a plate cylinder and an impression cylinder in the imprinting device, thereby reducing the downtime of the printing press due to maintenance of the imprinting device.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses a printing press imprinting device for printing on a substrate.

[0031] Reference Figure 1 and Figure 2 The printing press imprinting device includes a base body 1, a frame body 2, a plate cylinder 3, an impression cylinder 4, a first driving member 5, a second driving member 6 and a third driving member 7.

[0032] The base 1 is fixedly mounted on the top of the machine body 8. The machine body 8 is a rectangular parallelepiped structure as a whole, and the printing material 10 can move on the end surface of the top of the machine body 8 along the length direction of the machine body 8; the base 1 has a clearance space 11 inside for other structures to be installed and moved and for the printing material 10 to move through, and the printing material 10 can move through the bottom of the clearance space 11. In this embodiment, since the movement of the printing material 10 on the machine body 8 is a prior art in the art, its principle will not be described in detail here, and it is only briefly shown in the drawings.

[0033] The frame 2 includes a movable member 21 , a rotating frame 22 and two mounting components 23 .

[0034] The movable member 21 is installed in the clearance space 11 and is movably connected with the base body 1 in the vertical direction; the first driving member 5 is fixedly installed on the top of the base body 1 and can drive the movable member 21 to move relative to the base body 1. In this embodiment, the first driving member 5 is preferably a servo cylinder; since the servo cylinder is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0035] One end of the rotating frame 22 is rotatably connected to the movable member 21, and its rotation axis is horizontal and perpendicular to the moving direction of the substrate 10; the second driving member 6 is fixedly mounted on the movable member 21, and can drive the rotating frame 22 to rotate relative to the movable member 21. In this embodiment, the second driving member 6 is preferably a servo motor; since the servo motor is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0036] The second driving member 6 has a limit in the process of driving the rotating frame 22 to rotate. When the second driving member 6 drives the rotating frame 22 to rotate to the extreme position in the direction close to the machine body 8, the rotating frame 22 is in a vertical state and is completely located in the clearance space 11; when the second driving member 6 drives the rotating frame 22 to rotate to the extreme position in the direction away from the machine body 8, the rotating frame 22 is in a horizontal state and is located on one side of the clearance space 11.

[0037] The mounting assembly 23 is mounted on one end of the rotating frame 22 away from the movable member 21 , and two mounting assemblies 23 are respectively located on two sides of the rotating frame 22 .

[0038] Reference Figure 3 and Figure 4 The mounting assembly 23 includes a mounting seat 231, a first cover body 232 and a second cover body 233, wherein the first cover body 232 and the second cover body 233 correspond to the plate cylinder 3 and the impression cylinder 4 respectively, and the plate cylinder 3 can be rotatably connected with the mounting seat 231 through the cooperation between the mounting seat 231 and the first cover body 232, and the impression cylinder 4 can be rotatably connected with the mounting seat 231 through the cooperation between the mounting seat 231 and the second cover body 233.

[0039] Reference Figure 2 and Figure 5 The plate cylinder 3 and the impression cylinder 4 are both cylindrical structures as a whole. Both ends of the plate cylinder 3 in the axial direction have a first shaft body 31 extending outward along its own axial direction, and both ends of the impression cylinder 4 in the axial direction have a second shaft body 41 extending outward along its own axial direction.

[0040] The mounting seat 231 is provided with a first mounting groove 2311 adapted to the first shaft body 31 and a second mounting groove 2312 adapted to the second shaft body 41, and the second mounting groove 2312 is located on the side of the first mounting groove 2311 away from the rotating frame 22; the first cover body 232 has a structure adapted to the first shaft body 31, and the second cover body 233 also has a structure adapted to the second shaft body 41.

[0041] The first cover 232 and the second cover 233 are both detachably connected to the mounting seat 231. When the two first shafts 31 on the plate cylinder 3 are respectively inserted into the two first mounting grooves 2311 on the two mounting seats 231, the two first covers 232 are respectively fixed on the two mounting seats 231, and the two first covers 232 will respectively embrace the two first shafts 31, so that the plate cylinder 3 is rotatably connected on the mounting seat 231, and the rotation axis thereof coincides with the axis of the plate cylinder 3 itself and is parallel to the rotation axis of the rotating frame 22; when the two second shafts 41 on the impression cylinder 4 are respectively inserted into the two second mounting grooves 2312 on the two mounting seats 231, the two second covers 233 are respectively fixed on the two mounting seats 231, and the two second covers 233 will respectively embrace the two second shafts 41, so that the impression cylinder 4 is rotatably connected on the mounting seat 231, and the rotation axis thereof coincides with the axis of the impression cylinder 4 itself and is parallel to the rotation axis of the rotating frame 22. In this embodiment, the first cover body 232 and the second cover body 233 are preferably detachably connected to the mounting base 231 through screws; since the above-mentioned detachable connection method is a common prior art, it will not be described in detail here, and the related connection structures such as screws are omitted in the drawings.

[0042] When the plate cylinder 3 and the impression cylinder 4 are both rotatably connected on the mounting seat 231, the plate cylinder 3 is located on the side of the impression cylinder 4 close to the rotating frame 22, and the cylinder surface of the plate cylinder 3 contacts and abuts against the cylinder surface of the impression cylinder 4, and the rotation of the plate cylinder 3 relative to the connecting seat can drive the impression cylinder 4 to rotate in the opposite direction relative to the connecting seat synchronously. In this embodiment, the impression cylinder 4 is preferably a rubber cylinder, which can effectively ensure the friction between the plate cylinder 3 and the impression cylinder 4 after the contact between the two, and can also reduce the wear of the plate cylinder 3 caused by the contact between the two; since the rubber cylinder is a prior art in the field, it will not be described here, and it is only briefly shown in the drawings.

[0043] Reference Figure 1 When the second driving member 6 drives the rotating frame 22 to rotate to a vertical state, the first driving member 5 drives the movable member 21 to move relative to the base body 1, so that the impression roller 4 can be controlled to move toward the direction of the substrate 10, and the pressure of the impression roller 4 on the substrate 10 can be adjusted by controlling the first driving member 5, thereby adjusting the printing effect on the substrate 10.

[0044] Reference Figure 2 and Figure 5When the second driving member 6 drives the rotating frame 22 to rotate to a horizontal state, the plate cylinder 3 and the impression cylinder 4 are both located above the machine body 8 and on one side of the clearance space 11, and there is enough operating space around them for the staff to replace the plate cylinder 3 and the impression cylinder 4. At this time, the notches of the first mounting groove 2311 and the second mounting groove 2312 are both vertically upward, and the first cover body 232 and the second cover body 233 are both located above the mounting seat 231.

[0045] Reference Figure 3 and Figure 5 In order to facilitate the staff to replace the plate cylinder 3 and the impression cylinder 4, the frame 2 preferably also includes a support frame 24, an elastic member 25 and an operating member 26.

[0046] The support frame 24 is installed on one side of the rotating frame 22 and is adjacent to the first cover 232 . When the rotating frame 22 is in a horizontal state, the support frame 24 is located above the rotating frame 22 .

[0047] The support frame 24 is an arc-shaped frame body 2 structure as a whole, and has a groove 241 for temporarily placing the printing plate cylinder 3 or the impression cylinder 4, and the groove 241 corresponds to an arc-shaped groove. The support frame 24 is rotatably connected to the rotating frame 22, and its rotation axis is parallel to the rotation axis of the rotating frame 22, and the support frame 24 is symmetrical relative to its own rotation axis; the elastic member 25 is installed at the rotation connection position between the support frame 24 and the rotating frame 22, and its two ends are respectively fixedly connected to the support frame 24 and the rotating frame 22, and has a tendency to drive the support frame 24 to rotate to the extreme position away from the mounting seat 231 and maintain it; when the rotating frame 22 is in a horizontal state, the support frame 24 can keep the notch of the groove 241 facing vertically upward under the action of the elastic member 25. In this embodiment, the elastic member 25 is preferably a torsion spring; since the torsion spring is a common prior art, it is not described here, and it is only briefly shown in the drawings.

[0048] Reference Figure 3 and Figure 4 The operating member 26 is a rod-shaped structure as a whole, and one end of the operating member 26 in the length direction is rotatably connected to the end of the support frame 24 close to the mounting seat 231, and the rotation axis is parallel to the rotation axis of the support frame 24; the other end of the operating member 26 in the length direction passes through the rotating frame 22 and is located on the side of the rotating frame 22 away from the support frame 24, so that the staff can hold this end and apply force to the support frame 24 through the operating member 26 to drive it to overcome the force of the elastic member 25 and rotate in the direction close to the mounting seat 231.

[0049] When the support frame 24 rotates to the extreme position in the direction close to the mounting seat 231, the end of the groove wall of the groove 241 close to the mounting seat 231 will be close to the surface of the first cover plate away from the mounting seat 231, and after the first cover plate and the second cover plate are installed on the mounting seat 231, the surface of the first cover plate away from the mounting seat 231 is flush with the surface of the second cover plate away from the mounting seat 231.

[0050] Reference Figure 4 and Figure 5 When the plate cylinder 3 or the impression cylinder 4 is placed on the support frame 24, the plate cylinder 3 or the impression cylinder 4 will be in a position where the axis is parallel to the rotation axis of the support frame 24, and the corresponding two first shafts 31 or the two second shafts 41 will contact and abut against the groove wall of the groove 241.

[0051] At this time, after controlling the support frame 24 to rotate to the extreme position in the direction close to the mounting seat 231, the plate cylinder 3 or the impression cylinder 4 placed on the support frame 24 will roll along the arc trajectory of the support frame 24 in the direction close to the mounting seat 231, and after the plate cylinder 3 or the impression cylinder 4 rolls to the connecting seat, the corresponding first shaft body 31 or the second shaft body 41 can be inserted into the corresponding first positioning groove 242 or the second positioning groove 242, completing the preliminary installation of the plate cylinder 3 or the impression cylinder 4 on the mounting seat 231.

[0052] Furthermore, in order to facilitate the plate cylinder 3 or the impression cylinder 4 to stop on the mounting seat 231 after rolling, and to reduce the probability of the plate cylinder 3 or the impression cylinder 4 rolling off the mounting seat 231 due to inertia, a guide groove 2313 is preferably provided on the mounting seat 231.

[0053] When the rotating frame 22 is in a horizontal state, the guide groove 2313 is located above the first mounting groove 2311 and the second mounting groove 2312 on the mounting seat 231, and the guide groove 2313 is communicated with the first mounting groove 2311 and the second mounting groove 2312 at the same time; the guide groove 2313 is flared in a direction away from the first mounting groove 2311 and the second mounting groove 2312, so that the first axis 31 or the second axis 41 corresponding to the plate roller 3 or the impression roller 4 can be easily rolled into the guide groove 2313, and the first axis 31 or the second axis 41 corresponding to the plate roller 3 or the impression roller 4 can be lowered to roll away from the guide groove 2313.

[0054] The first cover 232 and the second cover 233 both have structures adapted to the guide groove 2313 . After both are installed on the mounting seat 231 , the guide groove 2313 can be filled.

[0055] During the process of replacing the plate roller 3, it is necessary to remove the corresponding two first cover bodies 232, and then control the support frame 24 to rotate to the extreme position in the direction close to the mounting seat 231. At this time, the two first shaft bodies 31 of the plate roller 3 will roll along the groove wall of the groove 241, so that the plate roller 3 moves in the direction close to the mounting seat 231; after the first shaft body 31 leaves the support frame 24, it will fall into the guide groove 2313 and contact the mounting seat 231. At this time, the two second cover bodies 233 will limit the rolling of the two first shaft bodies 31 in the guide groove 2313, and the contact between the plate roller 3 and the impression roller 4 can play a buffering effect, so that the two first shaft bodies 31 can be smoothly inserted into the corresponding first mounting groove 2311.

[0056] During the process of replacing the impression roller 4, it is necessary to remove the corresponding two second cover bodies 233, and then control the support frame 24 to rotate to the extreme position in the direction close to the mounting seat 231. At this time, the two second shaft bodies 41 of the impression roller 4 will roll along the groove wall of the groove 241, so that the impression roller 4 moves in the direction close to the mounting seat 231; after the second shaft body 41 leaves the support frame 24, it will first roll on the surface of the first cover body 232, and then fall into the guide groove 2313 and contact the mounting seat 231. At this time, the flared structure of the guide groove 2313 can effectively prevent the second shaft body 41 from rolling away in the guide groove 2313, so that the two second shaft bodies 41 can be smoothly inserted into the corresponding second mounting grooves 2312.

[0057] Furthermore, in order to improve the position accuracy of the plate cylinder 3 or the impression cylinder 4 when it is placed on the support frame 24, and to improve the position accuracy of the subsequent plate cylinder 3 or the impression cylinder 4 when it is replaced on the mounting seat 231, it is preferred that the plate cylinder 3 has a first positioning portion 311 extending outward along its own radial direction on the two first shafts 31, and the impression cylinder 4 has a second positioning portion 411 extending outward along its own radial direction on the two second shafts 41, and the support frame 24 has two positioning grooves 242 on the groove wall of the groove 241 that are adapted to the first positioning portion 311 and the second positioning portion 411.

[0058] The first positioning portion 311 and the second positioning portion 411 are both annular structures as a whole. The extension trajectory of the positioning groove 242 on the support frame 24 is the same as the arc trajectory of the support frame 24, and the positioning groove 242 has openings on the support frame 24 in the direction close to the groove 241 and in the direction close to the mounting seat 231.

[0059] At this time, when the printing plate cylinder 3 or the impression cylinder 4 is placed on the support frame 24, the corresponding two first shafts 31 or the two second shafts 41 will contact and abut against the groove wall of the groove 241, and the corresponding two first positioning portions 311 or the two second positioning portions 411 will be respectively inserted into the two positioning grooves 242; when the printing plate cylinder 3 or the impression cylinder 4 is moved to the mounting seat 231 for initial installation, the corresponding first positioning portion 311 or the second positioning portion 411 will be located between the two mounting seats 231.

[0060] Furthermore, in order to further facilitate the staff to correctly place the new plate cylinder 3 or impression cylinder 4 to be installed on the support frame 24, and at the same time facilitate the plate cylinder 3 or impression cylinder 4 to be correctly moved to the mounting seat 231 to successfully complete the initial installation, it is preferred that the positioning groove 242 is flared in the direction close to the groove 241, and is contracted along its own extension trajectory in the direction close to the mounting seat 231, and the first positioning portion 311 and the second positioning portion 411 can both be exactly matched with the portion of the positioning groove 242 close to the mounting seat 231.

[0061] Reference Figure 1 and Figure 5 The third driving member 7 is fixedly mounted on the movable member 21, and can drive the plate cylinder 3 to rotate relative to the mounting seat 231. In this embodiment, the third driving member 7 is preferably a servo motor.

[0062] Furthermore, in order to improve the stability of the third driving member 7 driving the plate cylinder 3 to rotate, two synchronous belts 9 for transmission are preferably installed between the third driving member 7 and the plate cylinder 3, and the plate cylinder 3 has synchronous wheels 32 adapted to the synchronous belts 9 at the ends of the two first shafts 31.

[0063] The output shaft of the third driving member 7 has two corresponding hub structures 71 for the synchronous belt 9 to be wound around. The axis of the hub structure 71 is parallel to the rotation axis of the rotating frame 22, and the two hub structures 71 are respectively aligned with the two synchronous wheels 32 along their respective radial directions; the axis of the synchronous wheel 32 coincides with the axis of the plate cylinder 3. After the plate cylinder 3 is installed on the two mounting seats 231, the two mounting seats 231 will be located between the two synchronous wheels 32; the synchronous belt 9 is respectively wound around the corresponding hub structure 71 and the synchronous wheel 32, and the third driving member 7 can drive the output shaft to rotate and drive the two hub structures 71 to rotate, thereby driving the plate cylinder 3 to rotate relative to the connecting seat through the two synchronous belts 9. In this embodiment, since the pulley drive is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0064] Furthermore, it is preferred that the minimum distance between the axis of the plate cylinder 3 and the axis of the output shaft of the third drive member 7 when the rotating frame 22 is in a horizontal state is smaller than the minimum distance between the axis of the plate cylinder 3 and the axis of the output shaft of the third drive member 7 when the rotating frame 22 is in a vertical state.

[0065] Correspondingly, when the rotating frame 22 is in a horizontal state, the synchronous belt 9 installed between the third driving member 7 and the plate cylinder 3 is in a loose state, which can facilitate the staff to disassemble and assemble, release the synchronization relationship between the third driving member 7 and the plate cylinder 3, or form a synchronization relationship between the third driving member 7 and the plate cylinder 3; when the rotating frame 22 is in a vertical state, the synchronous belt 9 installed between the third driving member 7 and the plate cylinder 3 is in a taut state, which effectively ensures the stability and synchronization of the third driving member 7 driving the plate cylinder 3 to rotate.

[0066] The implementation principle of a printing press imprinting device in the embodiment of the present application is as follows: When the printing plate cylinder 3 or the impression cylinder 4 needs to be replaced, the first driving member 5 is first controlled to drive the movable member 21 to move upward to a certain height, and then the second driving member 6 is controlled to drive the rotating frame 22 to rotate to a horizontal state, and then the corresponding first cover body 232 or second cover body 233 is removed, and then the original printing plate cylinder 3 or impression cylinder 4 is hoisted and removed; then the new printing plate cylinder 3 or impression cylinder 4 to be installed is placed on the support frame 24, so that the corresponding first positioning portion 311 or second positioning portion 411 is engaged with the positioning groove 242; and then the support frame 24 is controlled by the operating member 26 to move closer to the mounting seat 231 The plate cylinder 3 or the impression cylinder 4 is rotated to the extreme position in the direction of the mounting seat 231, and the corresponding first shaft body 31 or the second shaft body 41 rolls along the groove wall of the groove 241 and enters the guide groove 2313, and then enters the corresponding first mounting groove 2311 or the second mounting groove 2312 in the guide groove 2313, completing the preliminary installation of the plate cylinder 3 or the impression cylinder 4 on the mounting seat 231; finally, the corresponding first cover body 232 or the second cover body 233 is installed on the mounting seat 231, so that the new plate cylinder 3 or the impression cylinder 4 is rotatably connected with the mounting seat 231; If the printing plate cylinder 3 is replaced, the synchronous belt 9 needs to be disassembled and assembled during the replacement process.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
