Description

Technical Field

[0001] This invention relates to the field of printing technology, specifically to a uniform printing structure for a printing press and its usage method. Background Technology

[0002] Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Their working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the press to the areas of the printing plate containing the text and images, and the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate. The invention and development of the printing press have played a vital role in the dissemination of human civilization and culture.

[0003] Currently, the printing mechanism of printing presses not only has a single structure and function, but also when printed materials are printed by the printing mechanism, impurities attached to the surface of the printed materials can cause uneven printing, affecting the quality of the printing and the reliability of the printing operation of the printing mechanism in the printing press. Summary of the Invention

The output end of the stepper motor passes through the upper surface of the adjustment block and is fixedly connected to the lead screw via a coupling. The lower end of the lead screw is rotatably connected to the lower surface of the sliding groove. A slider matching the sliding groove is threaded onto the lead screw. One end of the slider extends outside the sliding groove and is fixedly connected to the L-shaped support base.

[0008] As a further embodiment of the present invention: the front and rear ends of the adjustment block one are fixedly connected with rib one, the lower surface of rib one is fixedly connected with the upper surface of the base, the upper and lower surfaces of the slider one are fixedly connected with rib two, and the side of rib two is fixedly connected with the side of the L-shaped support seat.

[0009] As a further aspect of the present invention, the upper surface of the L-shaped support base is fixedly connected to two parallel ribs.

[0010] As a further embodiment of the present invention: the angle adjustment mechanism includes a second stepper motor, a second adjustment block, a second slider, a second lead screw, an adjustment rod, an adjustment plate, and a rotating shaft. The second adjustment block is fixedly connected to the upper surface of the L-shaped support base. A second sliding groove is opened on one side of the second adjustment block. The second stepper motor is mounted on the upper surface of the second adjustment block. The output end of the second stepper motor passes through the upper surface of the second adjustment block and is fixedly connected to the second lead screw through a coupling. The lower end of the second lead screw is rotatably connected to the lower surface of the second sliding groove. A second slider matching the second sliding groove is threaded onto the second lead screw. An adjustment rod is hinged to one side of the second slider. A through cavity is opened on the L-shaped support base. An adjustment plate is arranged in the through cavity. A rotating shaft is fixedly connected to both the front and rear ends of the adjustment plate. The rotating shaft is rotatably connected to the inner side of the through cavity. The other end of the adjustment rod is hinged to the upper surface of the adjustment plate. The printing press is connected to the lower surface of the adjustment plate.

[0011] As a further aspect of the present invention: a connecting block is fixedly connected to the upper surface of the printing machine, and a mounting plate is fixedly connected to the upper surface of the printing machine by a plurality of evenly distributed bolts.

[0012] As a further embodiment of the present invention: the impurity removal mechanism further includes a dustproof net, a dust collection box and an air inlet pipe. The dust collection box is fixedly connected to the upper surface of the L-shaped support base, and a matching dustproof net is fixedly connected inside the dust collection box. The inlet of the fan is fixedly connected to the air inlet pipe, and the other end of the air inlet pipe is fixedly connected to the side of the dust collection box.

[0013] As a further aspect of the present invention: the lower end of the doctor blade is level with the horizontal height of the printing head of the printing machine.

[0014] A method for using a uniform printing structure for a printing press, with the following specific operating steps:

[0015] a. First, start stepper motor one. The rotation of stepper motor one drives the rotation of lead screw one. The rotation of lead screw one drives slider one to slide in the slide groove one on the side of adjustment block one. The movement of adjustment block one drives the movement of L-shaped support seat. The movement of L-shaped support seat drives the movement of angle adjustment mechanism, so that the printing press connected to the angle adjustment mechanism can move accordingly, and the height of the printing press can be adjusted to suit the printed matter.

[0016] b. Restart stepper motor two. The rotation of stepper motor two drives the rotation of lead screw two. The rotation of lead screw two can drive slider two to slide in the slide groove two on the side of adjustment block two. By rotating stepper motor two forward and backward, the height of slider two can be adjusted. One end of adjustment rod is hinged to slider two, and the other end is hinged to adjustment plate. One end of adjustment plate can rotate through a rotating shaft. Thus, the up and down movement of slider two can pull up or down one end of adjustment plate through adjustment rod, so that adjustment plate rotates around the rotating shaft and the angle of adjustment plate can be stably adjusted. This allows for stable adjustment of the tilt angle of the printing press, making the tilt angle of the printing press suitable for printing materials.

[0017] c. After adjustment, printing is carried out using the printing press. During the printing process, the blower is started, and the air from the blower is introduced into the air pipe through a flexible hose and then discharged through the oblique hole. The airflow can blow away the tiny dust impurities on the surface of the printed matter. Moreover, during the printing process, the squeegee can be adjusted with the angle of the printing press to always be directly facing the printed matter. Since the lower end of the squeegee is level with the printing head of the printing press, it can scrape away stubborn impurities attached to the surface of the printed matter as it is fed to the base below the printing press. In addition, during the impurity removal process, when the blower is venting, the air is drawn into the dust collection box through the air inlet pipe, filtered through the dust screen, and then drawn away for dust removal and reuse, avoiding the influence of dust impurities in the air on the impurity removal process.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention features a height adjustment mechanism that allows for convenient and quick adjustment of the printing press height, facilitating printing on materials of varying heights. An angle adjustment mechanism that allows for stable adjustment of the printing press tilt angle facilitates printing on materials at different tilt angles. This versatility enhances the applicability of the device.

[0020] This invention, through its impurity removal mechanism, can easily remove minute dust impurities and stubborn adhering impurities from printed materials, preventing impurities from causing uneven printing, thereby improving printing quality and enhancing the reliability of the printing press.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6 In this embodiment of the invention, a uniform printing structure for a printing press includes a base 1, a height adjustment mechanism 2, an L-shaped support 3, an angle adjustment mechanism 4, a printing press 5, and a cleaning mechanism 6.

[0030] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 5As shown, a height adjustment mechanism 2 for adjusting the printing height is connected to the base 1. An L-shaped support base 3 is fixedly connected to the height adjustment mechanism 2. An angle adjustment mechanism 4 for adjusting the printing angle is connected to the L-shaped support base 3. A printing machine 5 is connected to the angle adjustment mechanism 4. A cleaning mechanism 6 is connected to the printing machine 5.

[0031] It should be noted that during operation, the height of the printing press 5 is first adjusted using the height adjustment mechanism 2 to accommodate printing materials of different heights. Then, the angle is adjusted using the angle adjustment mechanism 4 to accommodate printing materials with different tilt angles. After adjustment, printing begins. During printing, the blower 65 is activated, and the air from the blower 65 is introduced into the air duct 67 through the hose 66 and then discharged through the oblique hole. The airflow removes fine dust and impurities from the surface of the printed material. Furthermore, during printing, the doctor blade 62 adjusts accordingly with the angle of the printing press 5, always facing the printed material. The lower end of 62 is level with the printing head of the printing machine 5, so that during the process of feeding the printed matter onto the base 1 and below the printing machine 5, it can scrape off the stubborn impurities attached to the surface of the printed matter. This can easily remove the tiny dust impurities and stubborn impurities attached to the printed matter, avoid impurities causing uneven printing, and thus improve the printing quality. At the same time, it can improve the reliability of the printing machine 5. Moreover, during the impurity removal process, when the fan 65 is venting, the gas is drawn into the dust collection box 69 through the air inlet pipe 610. After being filtered by the dust filter 68, it is drawn away for dust removal and reuse, avoiding the dust impurities in the gas from affecting the impurity removal, thereby improving the impurity removal effect.

[0032] refer to Figure 1 , Figure 2 and Figure 3 As shown, the height adjustment mechanism 2 includes an adjustment block 21, a stepper motor 22, a lead screw 23, and a slider 24. The adjustment block 21 is fixedly connected to the upper surface of the base 1. A sliding groove is provided on one side of the adjustment block 21. The stepper motor 22 is installed on the upper surface of the adjustment block 21. The output end of the stepper motor 22 passes through the upper surface of the adjustment block 21 and is fixedly connected to the lead screw 23 through a coupling. The lower end of the lead screw 23 is rotatably connected to the lower surface of the sliding groove. A slider 24 matching the sliding groove is threaded on the lead screw 23. One end of the slider 24 extends outside the sliding groove and is fixedly connected to the L-shaped support base 3.

[0033] It should be noted that when adjusting the height, stepper motor 22 is started. The rotation of stepper motor 22 drives the rotation of lead screw 23. The rotation of lead screw 23 causes slider 24 to slide in the groove on the side of adjusting block 21. The movement of adjusting block 21 drives the movement of L-shaped support 3. The movement of L-shaped support 3 drives the movement of angle adjustment mechanism 4, so that printing press 5 connected to angle adjustment mechanism 4 can move accordingly. Thus, by rotating stepper motor 22 in both directions, the height of printing press 5 can be adjusted conveniently and quickly, which is convenient for printing on materials of different heights and improves the applicability of the device.

[0034] refer to Figure 3 As shown, the front and rear ends of the adjusting block 21 are fixedly connected with ribs 8. The lower surface of ribs 8 is fixedly connected to the upper surface of the base 1. The upper and lower surfaces of the slider 24 are fixedly connected with ribs 7. The side of ribs 7 is fixedly connected to the side of the L-shaped support 3. By setting ribs 8, the adjusting block 21 can be more stably connected to the base 1. By setting ribs 7, the L-shaped support 3 can be stably connected to the slider 24.

[0035] refer to Figure 2 As shown, two parallel ribs 9 are fixedly connected to the upper surface of the L-row support base 3. The ribs 9 make the structure of the L-row support base 3 more stable, improve its support effect, and prevent deformation.

[0036] refer to Figure 1 , Figure 2 and Figure 4 As shown, the angle adjustment mechanism 4 includes a second stepper motor 41, a second adjustment block 42, a second slider 43, a second lead screw 44, an adjustment rod 45, an adjustment plate 46, and a rotating shaft 47. The second adjustment block 42 is fixedly connected to the upper surface of the L-shaped support base 3. A second sliding groove is provided on one side of the second adjustment block 42. The second stepper motor 41 is mounted on the upper surface of the second adjustment block 42. The output end of the second stepper motor 41 passes through the upper surface of the second adjustment block 42 and is fixedly connected to the second lead screw 44 via a coupling. The lower end of 44 is rotatably connected to the lower surface of the slide groove 2. The screw 2 44 is threaded with a slider 2 43 that matches the slide groove 2. One side of the slider 2 43 is hinged with an adjusting rod 45. The L-shaped support 3 has a through cavity. An adjusting plate 46 is installed in the through cavity. The front and rear ends of the adjusting plate 46 are fixedly connected with a rotating shaft 47. The rotating shaft 47 is rotatably connected to the inner side of the through cavity. The other end of the adjusting rod 45 is hinged to the upper surface of the adjusting plate 46. The printing machine 5 is connected to the lower surface of the adjusting plate 46.

[0037] It should be noted that when angle adjustment is required, stepper motor 41 is started. The rotation of stepper motor 41 drives the rotation of lead screw 44. The rotation of lead screw 44 causes slider 43 to slide in the groove on the side of adjusting block 42. By rotating stepper motor 41 in both directions, the height of slider 43 can be adjusted. One end of adjusting rod 45 is hinged to slider 43, and the other end is hinged to adjusting plate 46. One end of adjusting plate 46 can rotate through shaft 47. Thus, the up and down movement of slider 43 can pull up or down one end of adjusting plate 46 through adjusting rod 45, causing adjusting plate 46 to rotate around shaft 47. This allows for stable adjustment of the angle of adjusting plate 46, thereby stably adjusting the tilt angle of printing press 5. This facilitates the use of printing materials with different tilt angles and improves the applicability of the device.

[0038] refer to Figure 6 As shown, the upper surface of the printing machine 5 is fixedly connected to a connecting block 10 and a mounting plate 11. The mounting plate 11 is fixedly connected to the lower surface of the adjusting plate 46 by a plurality of evenly distributed bolts, so that the printing machine 5 can be easily and quickly removed from the mounting plate 11 for easy inspection and maintenance.

[0039] A method for using a uniform printing structure for a printing press, with the following specific operating steps:

[0040] a. First, start the stepper motor 22. The rotation of the stepper motor 22 drives the rotation of the lead screw 23. The rotation of the lead screw 23 drives the slider 24 to slide in the groove on the side of the adjusting block 21. The movement of the adjusting block 21 drives the movement of the L-shaped support 3. The movement of the L-shaped support 3 drives the movement of the angle adjustment mechanism 4, so that the printing press 5 connected to the angle adjustment mechanism 4 can move accordingly, and the height of the printing press 5 can be adjusted to suit the printed matter.

[0041] b. Restart stepper motor 41. The rotation of stepper motor 41 drives the rotation of lead screw 44. The rotation of lead screw 44 causes slider 43 to slide in the groove on the side of adjusting block 42. By rotating stepper motor 41 in both directions, the height of slider 43 can be adjusted. One end of adjusting rod 45 is hinged to slider 43, and the other end is hinged to adjusting plate 46. One end of adjusting plate 46 can rotate through shaft 47. Thus, the up and down movement of slider 43 can pull up or down one end of adjusting plate 46 through adjusting rod 45, so that adjusting plate 46 rotates around shaft 47, and the angle of adjusting plate 46 can be stably adjusted, thereby stably adjusting the tilt angle of printing press 5, so that the tilt angle of printing press 5 can be adjusted to suit the printed matter.

[0042] c. After adjustment, printing is performed using printing press 5. During printing, fan 65 is started, and the air from fan 65 is introduced into air pipe 67 through hose 66 and then discharged through oblique hole. The airflow can blow away tiny dust impurities on the surface of the printed matter. Moreover, during printing, the doctor blade 62 can be adjusted with the angle of printing press 5, always facing the printed matter. Since the lower end of doctor blade 62 is level with the printing head of printing press 5, stubborn impurities attached to the surface of the printed matter can be scraped away when the printed matter is fed to the base 1 below printing press 5. In addition, during the impurity removal process, when fan 65 is venting, the air is drawn into dust collection box 69 through air inlet pipe 610, filtered through dust screen 68 and then drawn away for dust removal and reuse, avoiding the influence of dust impurities in the air on the impurity removal.
