Description

Technical Field

[0001] The invention relates to the technical field of printing machines, in particular to a synchronous lifting structure of a paperboard support of an automatic printing machine. Background Art

[0002] The automatic printing machine is a high-efficiency, high-precision printing equipment, usually used in large-scale commercial printing, packaging printing and other fields. It can automatically complete the printing process, including paper conveying, inking, printing, drying and other links, greatly improving the printing efficiency and quality. The synchronous lifting structure of the paperboard of the automatic printing machine is used to support and convey the printing materials, ensuring the smooth conveying and positioning of the paper during the printing process.

[0003] After searching, Chinese patent No. CN202322344551.7 discloses a synchronous lifting mechanism for a paper support board of an automatic printing press, including a wall, an eccentric gear and a paper support board member. A linear guide rail is fixedly installed on the side of the wall close to the eccentric gear, and a slider is slidably connected to the outer wall of the linear guide rail. The slider is fixedly connected to the paper support board member, and a connecting component for cooperating with the eccentric gear is arranged on the outer side of the slider. A connecting sleeve is fixedly installed on the top of the slider, and a positioning component for fixing the connecting sleeve and the linear guide rail is arranged on the inner wall of the connecting sleeve.

[0004] The beneficial effects of the above device are as follows: as the eccentric gear rotates, the eccentric gear pushes the convex strip and the positioning plate to move upward, and the positioning plate is linked to the slider. While the slider slides vertically along the linear guide rail, the slider drives the paper support paper part to adjust its height, and in this process, the connecting sleeve will follow the slider to slide synchronously along the linear guide rail. After the paper support paper part is adjusted to the specified height, the positioning rod is rotated, and the positioning rod and the inner surface wall of the connecting sleeve are screwed together until the open end of the positioning rod abuts against the outer surface wall of the linear guide rail. At this time, the fixing of the connecting sleeve and the linear guide rail is achieved through friction force, thereby realizing the vertical limiting of the slider and the paper support paper part, thereby realizing the synchronous lifting and lowering of the paper support paper part and ensuring the stable operation of the paper support paper part.

[0005] During the operation of the existing synchronous lifting structure of the paper support of the printing press, although the paper support can be limited and fixed after the paper support moves to the target point, the stable movement of the paper support is achieved and the material on the paper support is accurately positioned. However, during the movement of the paper support, the paper support is affected by the transmission vibration of the mechanical structure, which will cause the material placed on the surface to vibrate and deviate, resulting in positioning errors of the conveyed materials after the degreasing plate moves to the target point. To this end, we propose a synchronous lifting structure of the paper support for an automatic printing press. Summary of the invention

[0026] Example

[0027] See also Figure 1-7 , the present invention provides a technical solution:

[0028] A synchronous lifting structure for a paperboard support of an automatic printing machine, wherein a slide rail 2 is fixedly connected to the surface of a base plate 1, the slide rail 2 is vertically arranged, a lifting platform 3 is slidingly installed on the surface of the slide rail 2, a paperboard support member 4 is fixedly connected to the surface of the lifting platform 3, the paperboard support member 4 is used to support the printed paper, and further, during the linear sliding process of the lifting platform 3 on the surface of the slide rail 2, the height of the paperboard support member 4 can be adjusted, thereby further controlling the lifting and lowering of the supported printed paper.

[0029] The surface of the base plate 1 is fixedly connected with a motor 7, and an eccentric wheel 8 is fixedly connected to the output shaft of the motor 7. At the same time, a push block 9 is fixedly connected to the surface of the lifting platform 3. The push block 9 is provided with an arc groove 10 on the side of the surface facing the eccentric wheel 8, and the push block 9 is adaptively abutted against the surface of the arc groove 10. Further, after the motor 7 is turned on, the motor 7 drives the eccentric wheel 8 to rotate, and the eccentric wheel 8 will abut against the surface of the arc groove 10 during the rotation process and push the push block 9 to slide. The lifting platform 3 is adaptively installed on the slide rail 2, so that when the slide rail 2 limits the lifting platform 3, the push block 9 will push the lifting platform 3 to slide linearly on the surface of the slide rail 2, and further realize the lifting and lowering adjustment of the paper supporting paper member 4.

[0030] The surface of the paper support member 4 is fixedly connected with a transverse leveling mechanism 5 and a longitudinal leveling mechanism 6, and the transverse leveling mechanism 5 and the longitudinal leveling mechanism 6 are vertically distributed. When the printed paper is placed on the surface of the paper support member 4 and is lifted and lowered as the paper support member 4 is lifted and lowered, the paper support member 4 is affected by the vibration of the mechanical structure when it moves, which causes the printed paper to vibrate and slide on the surface of the paper support member 4, further causing the printed paper to be displaced on the surface of the paper support member 4, resulting in errors in the positioning of the printed paper, and further causing printing misalignment. Through the structural operation of the transverse leveling mechanism 5 and the longitudinal leveling mechanism 6, the printed paper on the surface of the paper support member 4 can be positioned and reset during the lifting and lowering process of the paper support member 4, so that the printed paper can be neatly stacked on the surface of the paper support member 4, and the position of the printed paper will not be shifted due to the vibration generated by the movement of the paper support member 4, further improving the printing accuracy of the printing press.

[0031] The paper support member 4 includes a fixed support plate 401 fixedly connected to the surface of the lifting platform 3, and the fixed support plate 401 is used to lay the printed paper flat. A movable support plate 402 is installed on the surface of the fixed support plate 401, and the support area of ​​the surface of the fixed support plate 401 can be increased by the movable support plate 402, which further facilitates the paper support member 4 to support a larger area of ​​printed paper, thereby improving the applicability of the device. A damping hole 403 is provided on the surface of the fixed support plate 401 facing the movable support plate 402, and a damping plug rod 404 is fixedly connected to the surface of the movable support plate 402 facing the fixed support plate 401, and the damping plug rod 404 is inserted in the damping hole 403 in a matching manner. Further, the damping plug rod 404 is made to slide inside the damping hole 403, so that the distance between the fixed support plate 401 and the movable support plate 402 can be adjusted, so that the fixed support plate 401 and the movable support plate 402 can support and place printed paper of different lengths, thereby improving the applicability of the device. The surface of the fixed support plate 401 is provided with a threaded hole which is connected to the damping hole 403, and a fixing bolt 405 is inserted in the threaded hole on the surface of the fixed support plate 401. When the damping rod 404 is slidably adjusted inside the damping hole 403, the fixing bolt 405 is tightened in the threaded hole and abuts against the surface of the damping rod 404, thereby increasing the sliding friction of the damping rod 404 inside the damping hole 403, further realizing the limited fixation of the damping rod 404 inside the damping hole 403, realizing the fixation of the fixed support plate 401 and the movable support plate 402 after the distance is adjusted, and ensuring the structural stability of the paper support member 4 when supporting and lifting the printed paper.

[0032] The surface of the movable support plate 402 away from the fixed support plate 401 is fixedly connected with two groups of hinged protrusions 406, and the horizontal leveling mechanism 5 includes a mounting shaft A501 inserted between the two groups of hinged protrusions 406, and the surface of the mounting shaft A501 is fixedly connected with a gear 502. The surface of the base plate 1 is fixedly connected with a fixed block 11, and a threaded hole is provided inside the fixed block 11, and a threaded rod 12 is inserted into the threaded hole. The threaded rod 12 is sleeved with a movable block 13 on the surface of one end of the threaded rod 12 facing the paper support member 4, and the surface of the movable block 13 is fixedly connected with a connecting rod 14, which is set in an "L" shape, and the surface of the connecting rod 14 facing the paper support member 4 is fixedly connected with a rack 15. When the spacing between the fixed support plate 401 and the movable support plate 402 is adjusted, the threaded rod 12 rotates inside the fixed block 11 to push the movable block 13 to slide on the surface of the base plate 1, and further adjusts the spacing of the rack 15 relative to the side of the paper support member 4 until the rack 15 and the gear 502 are meshed. When the paper support member 4 is in the process of being lifted or lowered, the gear 502 is driven to slide relatively along the surface of the rack 15. Further, through the meshing action of the rack 15 and the gear 502, the paper support member 4 is synchronously driven to rotate the mounting shaft A501 during the lifting or lowering process, thereby controlling the transverse flattening mechanism 5 to run on the surface of the paper support member 4, so that the transverse flattening mechanism 5 can position and reset the transverse edge of the printed paper placed on the surface of the paper support member 4.

[0033] A rotating disk A503 is fixedly connected to the surface of one end of the mounting shaft A501, a convex shaft A504 is fixedly connected to the non-center portion of the surface of the rotating disk A503, and a push rod A505 is hingedly installed on the surface of the convex shaft A504. A limited sliding groove A506 is arranged on the surface of the movable support plate 402 facing the rotating disk A503, a transverse slider A507 is inserted inside the limited sliding groove A506, and the transverse slider A507 is arranged in an "L" shape and protrudes from the surface of the limited sliding groove A506. A fixed shaft A508 is fixedly connected to the surface of the transverse slider A507, and the other end of the push rod A505 is sleeved on the surface of the fixed shaft A508. When the gear 502 meshes with the rack 15 and rotates and drives the mounting shaft A501 to rotate, the turntable A503 will be driven to rotate synchronously. During the rotation of the turntable A503, the convex shaft A504 will be driven to rotate, and the convex shaft A504 will further push the transverse slider A507 to slide inside the limiting slide groove A506. Under the limiting action of the limiting slide groove A506, the transverse slider A507 will reciprocate linearly inside the limiting slide groove A506. The upper end surface of the transverse slider A507 is fixedly connected with a cross bar 509, and the surface of the cross bar 509 is sleeved with a sliding sleeve A510. The surface of the sliding sleeve A510 is fixedly connected with a transverse push plate 512, and the lower end surface of the transverse push plate 512 abuts against the upper surface of the movable support plate 402. Further, during the reciprocating linear sliding process of the transverse slider A507 on the surface of the limiting slide groove A506, the transverse slider 512 will be pushed to reciprocate linearly on the surface of the movable support plate 402. When the printed paper is laid flat on the surface of the fixed support plate 401 and the movable support plate 402, the position of the transverse push plate 512 relative to the transverse edge of the printed paper is adjusted by sliding the sleeve A510 on the surface of the cross bar 509 according to the size of the paper, and the limiting bolt A511 inserted through the threaded hole on the surface of the sleeve A510 is further tightened, so that the sleeve A510 can be fixed after being adjusted on the surface of the cross bar 509. The surface of the fixed support plate 401 is fixedly connected to a limit stopper 407, and the limit stopper 407 is set in an "L" shape and installed at the corner position of the surface of the fixed support plate 401. The limit stopper 407 can limit the two side surfaces of the printed paper placed on the surface of the paper support plate 4, so that when the printed paper on the surface of the paper support plate 4 is affected by vibration and shifts in position during the movement of the paper support plate 4, the printed paper will slide toward the side away from the limit stopper 407, and the horizontal push plate 512 will contact the longitudinal edge of the printed paper during the reciprocating linear sliding process, so that the pushed paper can be reset and adjusted, thereby further maintaining the horizontal position accuracy of the printed paper when it is placed on the surface of the paper support plate 4.

[0034] The longitudinal leveling mechanism 6 includes a mounting plate 601 mounted on the surface of the fixed support plate 401, a mounting shaft B602 is inserted inside the mounting plate 601, the mounting shaft B602 and the mounting shaft A501 are vertically distributed, the mounting shaft B602 is fixedly connected to one end of the mounting shaft A501 with a bevel gear A603, and the other end of the mounting shaft A501 is fixedly connected to a bevel gear B604, and the bevel gear A603 and the bevel gear B604 are meshed and connected. Further, during the rotation of the mounting shaft A501, the bevel gear B604 will be driven to rotate in mesh with the bevel gear A603, and the bevel gear A603 will drive the mounting shaft B602 to rotate, so as to realize the driving of the longitudinal leveling mechanism 6, so that during the operation of the longitudinal leveling mechanism 6, the printed paper placed on the surface of the paper support member 4 can be longitudinally positioned and reset. A rotating disk B605 is fixedly connected to the surface of one end of the mounting shaft B602, a convex shaft B606 is fixedly connected to the non-center of the surface of the rotating disk B605, and a push rod B607 is hingedly installed on the surface of the convex shaft B606. A limited sliding groove B608 is arranged on the surface of the mounting plate 601, and a longitudinal slider 609 is inserted inside the limited sliding groove B608. The longitudinal slider 609 is arranged in an "L" shape and protrudes from the surface of the limited sliding groove B608. A fixed shaft B617 is fixedly connected to the surface of the longitudinal slider 609, and the other end of the push rod B607 is sleeved on the surface of the fixed shaft B617. The rotating disk B605 drives the push rod B607 to rotate during rotation, and further pushes the longitudinal slider 609 to slide inside the limited sliding groove B608 through the push rod B607, and under the limiting action of the limited sliding groove B608, the longitudinal slider 609 will reciprocate linearly inside the limited sliding groove B608. The upper end surface of the longitudinal slider 609 is fixedly connected with a longitudinal rod 610, and a sleeve B611 is installed on the surface of the longitudinal rod 610. The surface of the sleeve B611 is fixedly connected with a longitudinal fixed push plate 612, and the lower end surface of the longitudinal fixed push plate 612 abuts against the upper surface of the fixed support plate 401, and the longitudinal fixed push plate 612 and the transverse push plate 512 are vertically distributed. Further, the longitudinal slider 609 pushes the longitudinal fixed push plate 612 to slide reciprocatingly on the surface of the fixed support plate 401 during the reciprocating linear sliding process on the surface of the limiting slide groove B608. When the printed paper is laid flat on the surface of the fixed support plate 401 and the movable support plate 402, according to the size of the paper, the sleeve B611 slides on the surface of the longitudinal rod 610, and the limiting bolt B613 inserted in the threaded hole set on the surface of the sleeve B611 is tightened to abut against the surface of the longitudinal rod 610, so that the position of the transverse push plate 512 relative to the transverse edge of the printed paper can be adjusted and fixed.Furthermore, when the paper support member 4 is moving, when the printed paper on the surface of the paper support member 4 is affected by vibration and shifts in position, the printed paper will slide toward the side away from the limit block 407. The longitudinal fixed push plate 612 will contact the lateral edge of the printed paper during the reciprocating linear sliding process, and the pushed paper can be reset and adjusted, thereby further maintaining the longitudinal position accuracy of the printed paper when placed on the surface of the paper support member 4.

[0035] The surface of the longitudinal fixed push plate 612 is fixedly connected with a clamping sleeve 614, and a longitudinal movable push plate 615 is inserted inside the clamping sleeve 614. The surface of the clamping sleeve 614 is provided with a threaded hole, and a limiting bolt C616 is inserted in the threaded hole. When the spacing between the fixed support plate 401 and the movable support plate 402 is adjusted, the longitudinal movable push plate 615 slides inside the clamping sleeve 614 to further adjust the overall length of the longitudinal fixed push plate 612 and the longitudinal movable push plate 615, and the limiting bolt C616 is tightened in the threaded hole on the surface of the clamping sleeve 614 to contact the surface of the longitudinal movable push plate 615, so that the longitudinal movable push plate 615 can be fixed after adjustment. Ensure that the longitudinal flattening mechanism 6 performs positioning and resetting processing on the transverse edges of printed paper of different sizes.

[0036] This solution uses the structural settings of the paper support member 4, the transverse leveling mechanism 5, and the longitudinal leveling mechanism 6 to place printed papers of different sizes on the surface of the paper support member 4. Then, through the structural operation of the transverse leveling mechanism 5 and the longitudinal leveling mechanism 6, two sets of mutually perpendicular transverse push plates 512 and longitudinal fixed push plates 612 are controlled to reciprocate and abut against the edge of the printed paper, and one side of the printed paper is limited by the limit block 407. When the printed paper is subjected to mechanical vibration during the lifting process, causing the paper to slide and deviate on the surface of the paper support member 4, the reciprocating movement of the transverse push plate 512 and the longitudinal fixed push plate 612 can push the paper to return to its original position, thereby further ensuring the accuracy of the placement position of the paper on the surface of the paper support member 4.
