In addition, the printing efficiency and printing quality are greatly improved.

Description

Technical Field

[0001] The invention belongs to the technical field of printing, and in particular relates to a rapid replacement process for anilox rollers in printing. Background Art

[0002] Currently, the replacement of anilox rollers requires the following conditions: (1) ensuring their own levelness; (2) controlling the contact angle and ink volume of the scraper, ensuring a relatively uniform ink load without causing ink leakage from the ends. A common method is to form a carrier with a printing mechanism equipped with anilox rollers, replace and adjust the rollers on the carrier, and then install the entire carrier on the production line. This, however, has the following drawbacks:

[0003] 1) A carrier is heavy, which makes it very inconvenient to transfer and align during installation. It also requires further adjustment after installation, which is very laborious, and the accuracy cannot be guaranteed, and it takes a long time.

[0004] 2) After the anilox roller is installed, the scraper angle and position need to be further adjusted. In addition, the size of the ink storage area formed by the angle of the ordinary scraper module is uncontrollable. At the same time, as the metal anilox roller rotates, the ink will shake in the area, which not only makes it difficult to achieve relatively uniform ink supply, resulting in the ink load being unable to meet printing requirements (insufficient ink supply often occurs); and because of the shaking, the probability of ink leakage from the end is relatively high, which brings great inconvenience to the actual control of ink addition. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new process for quickly replacing anilox rollers in printing.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A process for quickly replacing anilox rollers during printing, comprising the following steps:

[0008] S1. Temporary storage of anilox roller

[0009] Place the anilox roller horizontally on the positioning support seat from the shaft end;

[0010] S2, rolling support of anilox roller

[0011] A power module and a driven module are provided on the left and right sides of the positioning support seat. The power module and the driven module are relatively close to each other to lift the anilox roller from the positioning support seat and keep the axis in a horizontal state to form a rolling support. At the same time, the anilox roller rotates and prints under the drive of the power module.

[0012] S3. Installation of scraper

[0013] The scraper rod is passed across the anilox roller through the brackets at both ends of the anilox roller, and the scraper end face of the corresponding scraper module is close to the inner wall of the anilox roller. Then, the position of the scraper rod is adjusted so that its rod core is flush with the center of the anilox roller. The scraper module is located below the scraper rod, and the scraper end face is attached to the lower right side of the inner wall, wherein the attached end of the scraper module forms an ink storage area with both ends blocked and the top open, and when the anilox roller is printing, the liquid level of the ink in the ink storage area is 1~3mm above the contact part between the scraper end face and the inner wall of the anilox roller, and at the same time, the cross-section of the ink storage area is gradually approached from both sides from top to bottom.

[0014] Preferably, in S1, there are two positioning support seats, each of which is formed with an arcuate groove with an upward opening, and the anilox roller is mounted on the arcuate groove from the shaft end.

[0015] According to a specific implementation and preferred aspect of the present invention, in S2, as the power module and the driven module move away from each other, the anilox roller falls back onto the positioning support seat, making it easier to disassemble and assemble the anilox roller.

[0016] Preferably, the power module is fixed and the driven module moves in a horizontal direction and moves closer to or farther from the power module. This is one embodiment, and of course the relative movement of the power module and the driven module can also be used to move the anilox roller upward or downward.

[0017] In some specific embodiments, a transmission gear is formed at the end of the anilox roller. The driven module includes a movable seat, upper and lower extrusion wheels arranged vertically, with the lower extrusion wheel located to the right of the upper extrusion wheel, and the upper and lower extrusion wheels rotate about their respective axes. The power module includes a coaxially arranged power gear and power wheel, and a motor. The power gear meshes with the transmission gear to form a transmission. The power wheel, upper and lower extrusion wheels are arranged in a triangular shape. The anilox roller is formed into a rolling support by rolling, laminating, and lifting. The relative motion of the three wheels allows the axis of the anilox roller to be adjusted to maintain a horizontal axis.

[0018] Preferably, the centers of the power wheel, upper squeeze wheel, and lower squeeze wheel form an isosceles triangle, with the line connecting the centers of the upper and lower squeeze wheels as the base, the center of the power wheel as the vertex, and the axis of the anilox roller located on the perpendicular line from the vertex to the base. Simply put, when printing with the anilox roller, the center of the triangle coincides with the axis of the anilox roller, which achieves optimal printing accuracy.

[0019] According to another specific implementation and preferred aspect of the present invention, in S3, the scraper module includes a first template extending downward from the scraper rod, a second template extending rightward and downward from the bottom of the first template, a third template extending upward from the right end of the second template, and a sealing template arranged at both ends of the second template and the third template, wherein the third template and the sealing template are both attached to the inner wall of the anilox roller from the end face, and the ink storage area is formed between the second template, the third template and the sealing template.

[0020] Preferably, the contact end surfaces of the third template and the end-sealing template are similar to and fully fit the inner wall surface of the anilox roller at the corresponding position, thereby avoiding ink leakage.

[0021] Furthermore, the S3 features a V- or U-shaped ink reservoir, with the vertical center plane of the V or U perpendicular to the horizontal plane after the scraper bar is installed. Furthermore, the S3 allows the scraper bar to be adjusted vertically to align the scraper end face with or away from the inner wall of the anilox roller. This allows the scraper module to be engaged or disengaged simply by adjusting the scraper bar vertically, facilitating quick anilox roller replacement.

[0022] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] The replacement of the existing anilox roller requires not only the disassembly and assembly of the entire carrier, but also the inability to maintain the horizontal accuracy of the axis of the anilox roller after docking, which is very laborious. At the same time, after the installation of the anilox roller is completed, the scraper angle and position need to be further adjusted. Moreover, the size of the ink storage area formed by the angle of the ordinary scraper module is uncontrollable. At the same time, as the metal anilox roller rotates, the ink will shake in the area, which not only makes it difficult to achieve relatively uniform ink supply, resulting in the ink carrying amount being unable to meet printing requirements (insufficient ink supply often occurs); and because of the shaking, the probability of ink leakage from the end is relatively high, which brings great inconvenience to the actual control of ink adding. The present invention cleverly solves the various deficiencies of the existing structure through the overall design of the anilox roller rapid replacement process. After adopting the quick-changing process of the anilox roller, the anilox roller is first horizontally mounted on the positioning support seat from the shaft end, and then, a power module and a driven module are provided on the left and right sides of the positioning support seat, wherein the power module and the driven module are relatively close to each other to lift the anilox roller from the positioning support seat and keep the axis line in a horizontal state to form a rolling support, and at the same time, driven by the power module, the anilox roller rotates and prints; then, the scraper rod is passed across the anilox roller through the brackets at both ends of the anilox roller, and the scraper end face of the corresponding scraper module is close to the inner wall of the anilox roller, and then, the position of the scraper rod is adjusted so that its rod core is flush with the center of the anilox roller, and the scraper module is located below the scraper rod, and the scraper end face is attached to the lower right side of the inner wall, wherein the attached end of the scraper module forms an ink storage area with both ends blocked and the top open, and when the anilox roller is printing, the liquid level of the ink in the ink storage area is between the scraper end face and the anilox roller 1~3mm above the contact part of the inner wall of the anilox roller, and the cross-section of the ink storage area is gradually approached from both sides from top to bottom, so that the replacement of the anilox roller is completed. Therefore, on the one hand, the present invention only needs to replace a single anilox roller, which can meet the printing needs, and the anilox roller is easy to disassemble and assemble. At the same time, the anilox roller automatically keeps the axis line in a horizontal state for transfer, meeting the needs of high-precision printing; on the other hand, the installation of the scraper rod and scraper module adopted makes the liquid level height of the ink in the ink storage area 1~3mm above the contact part between the scraper end face and the inner wall of the anilox roller, and the ink forms a small shaking amplitude in the ink storage area, and keeps the immersion type fit on the corresponding inner wall of the anilox roller, so that the ink carrying amount is not affected by the liquid level shaking, and the end sealing plate effectively prevents the ink from leaking from the end, and the user can add ink regularly, timed or quantitatively, which is convenient for operation. In addition, it also greatly improves the printing efficiency and printing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Combine Figures 1 to 8 As shown, the anilox roller quick-changing process in printing of this embodiment adopts an anilox roller quick-changing system including a disassembly and assembly seat 1, a positioning support seat 2, a drive module 3, and a scraper module 4, wherein the disassembly and assembly seat 1 is fixed to the printing assembly line; the positioning support seat 2 is used for horizontal positioning support of the anilox roller G, the drive module 3 is used for removing or returning the anilox roller G from the positioning support seat 2, and driving the anilox roller G to rotate for printing; the scraper module 4 is used for controlling the ink carrying amount of the anilox roller G.

[0040] The positioning support 2 includes two positioning modules 20 located at both ends of the anilox roller G and forming an upwardly opening arcuate groove 200 , wherein the arcuate groove 200 matches the axial end of the anilox roller G, and the axis of the anilox roller G is horizontally mounted on the two positioning modules 20 .

[0041] The drive module 3 includes a power module 30 and a driven module 31 located on either side of the positioning module 20, with the power module 30 located on the right side and the driven module 31 located on the left side. In this example, the power module 30 is fixed, while the driven module 31 moves horizontally, approaching or moving away from the power module 30. This is one embodiment; of course, the relative movement of the power module 30 and the driven module 31 can also be used to raise or lower the anilox roller G.

[0042] In some specific embodiments, the power module 30 includes a power gear 300, a motor 301, and a power wheel 302 that engage with the end of the anilox roller G; the driven module 31 includes a movable seat 310 that is slidably arranged on the disassembly and assembly seat 1 along the left and right directions, an upper extrusion wheel 311 and a lower extrusion wheel 312 installed on the movable seat 310, and a driven power source 313.

[0043] In this example, transmission gears m1 are respectively provided at both ends of the anilox roller G, and the power gear 300 and the power wheel 302 are coaxial, wherein there are two power gears 300 and they are respectively engaged with the transmission gears m1 at both ends, and the power wheel 302 rolls and fits on the shaft end of the anilox roller G; the lower extrusion wheel 311 is located on the right side of the upper extrusion wheel 312, and the upper extrusion wheel 311 and the lower extrusion wheel 312 rotate around their own axes. At the same time, the upper extrusion wheel 311, the lower extrusion wheel 312 and the power wheel 302 constitute a rolling support group, wherein the rolling support includes two rolling support groups, which are respectively arranged at the two shaft ends of the anilox roller G.

[0044] Combine Figure 4 and Figure 5As shown, the upper squeeze wheel 311, lower squeeze wheel 312, and power wheel 302 form an isosceles triangle, with the center of the triangle coinciding with the axis of the anilox roller G. This achieves optimal printing accuracy. In short, as the upper squeeze wheel 311 and lower squeeze wheel 312 move toward or away from the power wheel 302, the anilox roller G is removed from or retracted from the positioning module 20 while maintaining its axis horizontal.

[0045] To facilitate the movement of the driven module 31, in this example, a slide rail 314 extending in the left-right direction is provided on the disassembly and assembly base 1, and the movable base 310 is slidably provided on the slide rail 314. The two rolling support groups move synchronously with the movable base 310. At the same time, the driven power source 313 is a hydraulic cylinder or a pneumatic cylinder that moves in the left-right direction. The anilox roller G is mounted on the two positioning modules 20 from the shaft end. Then, the upper extrusion wheel 311 and the lower extrusion wheel 312 move synchronously to the right. First, the lower extrusion wheel 312 contacts the anilox roller G to push it out of the arc groove 200 and lift it upward to fit the power wheel 302. At the same time, the upper extrusion wheel 311 contacts the anilox roller G to support the anilox roller G in a rolling manner between the upper extrusion wheel 311, the lower extrusion wheel 312 and the power wheel 302. The transmission gear m1 and the power gear 300 are engaged and driven to realize the rotation and printing of the anilox roller G.

[0046] Recombination Figure 1 、 7 8. The scraper module 4 includes a scraper seat 40 that is detachable and mounted on both ends of the anilox roller G, a scraper rod 41 that is mounted on the scraper seat 40 and passes through the inside of the anilox roller G, and a scraper module 42 that is arranged on the scraper rod 41, wherein the scraper end of the scraper module 42 is attached to the inner wall of the anilox roller G, and the scraper end of the scraper module 42 forms an ink storage area c with both ends blocked and the top open. The liquid level of the ink in the ink storage area c is above the contact part between the scraper end and the inner wall of the anilox roller, and the liquid level is 1~3mm high. Generally, 2mm is sufficient. Once the liquid level is too low, the liquid surface moves due to the movement of the anilox roller, resulting in uneven ink loading; once the liquid level is too high, the liquid surface moves due to the movement of the anilox roller, resulting in ink leakage, affecting the printing quality.

[0047] Recombination Figure 1 and Figure 6As shown, the scraper holder 40 includes a holder body 400, a slider 401 that slides up and down on the holder body 400, and a scraper rod 41 that is inserted into the slider 401 from the end. The centerline of the scraper rod 41 is parallel to the axis of the anilox roller G and is arranged flush. At the same time, the scraper rod 41 is relatively close to the inner wall of the anilox roller G, which facilitates the scraping of excess ink on the inner wall and maintains a relatively uniform ink load. The scraper module 42 includes a first template 421 extending downward from the scraper rod 41, a second template 422 extending rightward and downward from the bottom of the first template 421, a third template 423 extending upward from the end of the second template 422, and end-sealing templates 424 disposed at both ends of the second and third templates 422, 423. The third and end-sealing templates 423 and 424 are attached to the inner wall of the anilox roller G from their end faces. An ink reservoir c is formed between the second, third, and end-sealing templates 422, 423, and 424. The angle formed between the second and third templates 422, 423 is an obtuse angle. Generally, this angle is between 160 and 175 degrees, but in this case, 166 degrees, which facilitates ink level control. The end-sealing template 424 is triangular in shape and fits flush at the junction of the second and third templates 422, 423.

[0048] In some specific embodiments, the contact end surfaces of the third template 423 and the end-sealing template 424 are similar to and fully aligned with the inner wall surface of the anilox roller G at the corresponding locations. Furthermore, the ink storage area has a V- or U-shaped cross-section, and after the scraper rod is installed, the vertical center plane of the V or U is perpendicular to the horizontal plane. Furthermore, in step S3, the scraper rod is adjusted up and down to ensure that the scraper end surface is relatively aligned with or separated from the inner wall of the anilox roller.

[0049] In this example, a straight rail 43 extending up and down is provided on the seat body 400, and the slider 401 is slidably set on the straight rail 43. The scraper module 4 also includes an adjustment bolt 44 that moves in the up and down directions and a fastening bolt 45 for fixing the slider 401 to the seat body 400.

[0050] In summary, the process for quickly changing the anilox roller during printing includes the following steps:

[0051] S1. Temporary storage of anilox roller

[0052] The anilox roller is mounted horizontally on a positioning support seat from the shaft end, wherein there are two positioning support seats, each positioning support seat is formed with an arc groove with an opening facing upwards, and the anilox roller is mounted on the arc groove from the shaft end;

[0053] S2, rolling support of anilox roller

[0054] The left and right sides of the positioning support seat are provided with a power module and a driven module. The power module is fixed, and the relative proximity of the driven module lifts the anilox roller from the positioning support seat and keeps the axis in a horizontal state to form a rolling support. At the same time, driven by the power module, the anilox roller rotates and prints;

[0055] S3. Installation of scraper

[0056] The scraper rod is passed across the anilox roller through the brackets at both ends of the anilox roller, and the scraper end face of the corresponding scraper module is close to the inner wall of the anilox roller. Then, the upper and lower positions of the scraper rod are adjusted by adjusting the bolt so that its rod core is flush with the center of the anilox roller. The scraper module is located below the scraper rod, and the scraper end face is attached to the lower right part of the inner wall. Then, the slider is fixed to the seat body with a fastening bolt, wherein the attached end of the scraper module forms a V-shaped ink storage area with both ends blocked and the top open. When the anilox roller is printing, the liquid level of the ink in the ink storage area is 1~3mm above the contact part between the scraper end face and the inner wall of the anilox roller.

[0057] In summary, after adopting the rapid replacement process of the anilox roller, the anilox roller is first horizontally mounted on the positioning support seat from the shaft end, wherein there are two positioning support seats, each of which is formed with an arc groove with an opening facing upward, and the anilox roller is matched and mounted on the arc groove from the shaft end; then, a power module and a driven module are provided on the left and right sides of the positioning support seat, wherein the power module is fixed, and the relative proximity of the driven modules lifts the anilox roller from the positioning support seat and keeps the axis line in a horizontal state to form a rolling support, and at the same time, driven by the power module, the anilox roller rotates and prints; then, the scraper rod is passed across the anilox roller through the brackets at both ends of the anilox roller, and the scraper end face of the corresponding scraper module is close to the inner wall of the anilox roller, and then, the upper and lower positions of the scraper rod are adjusted by adjusting the bolt so that the rod The core is flush with the center of the anilox roller, the scraper module is located below the scraper rod, and the scraper end face is attached to the lower right side of the inner wall, and then the slider is fixed to the seat body with a fastening bolt, wherein the attached end of the scraper module forms a V-shaped ink storage area with both ends blocked and the top open, and when the anilox roller is printing, the liquid level of the ink in the ink storage area is 1~3mm above the contact part between the scraper end face and the inner wall of the anilox roller, and the replacement of the anilox roller is completed. Therefore, on the one hand, the present invention only needs to replace a single anilox roller, which can meet the printing needs, and the anilox roller is easy to disassemble and assemble. At the same time, the anilox roller automatically keeps the axis line in a horizontal state for transfer, which meets the needs of high-precision printing; on the other hand, the installation of the scraper rod and scraper module adopted makes the ink in the ink storage area The liquid level height is 1~3mm above the contact part between the end face of the scraper and the inner wall of the anilox roller, and the ink has a small shaking amplitude in the ink storage area, while maintaining an immersion fit on the corresponding inner wall of the anilox roller, so that the ink carrying amount is not affected by the liquid level shaking. At the same time, the end sealing plate effectively prevents the ink from leaking from the end, and the user can add ink regularly, timed or quantitatively, which is convenient for operation. In addition, it also greatly improves the printing efficiency and printing quality.

On the fourth aspect, the upper extrusion wheel, the lower extrusion wheel and the power wheel are distributed in an isosceles triangle. When the anilox roller is printing, the center of the triangle It coincides with the axis of the anilox roller, and at this time, the printing accuracy can be best reflected; the fifth aspect is the position distribution of the scraper rod, which is convenient for the layout of the scraper module. At the same time, the scraper rod is relatively close to the inner wall of the anilox roller, which is more conducive to scraping off excess ink on the inner wall and maintaining a relatively uniform ink load; the sixth aspect is that the scraper end face of the scraper module is attached to the inner wall of the lower right side of the anilox roller, and the contact end faces of the third template and the sealing template are similar to and fully attached to the inner wall surface of the anilox roller at the corresponding position. At the same time, the cross-section of the ink storage area is V-shaped or U-shaped, and after the scraper rod is installed, the vertical center plane of the V-shaped or U-shaped is perpendicular to the horizontal plane. Under this design, as long as the scraper rod is lifted, the scraper module is directly separated from the ink roller, and excess ink can be retained in the ink storage area to complete the replacement of the anilox roller;Seventh, the angle formed between the second and third templates is an obtuse angle, typically between 160 and 175 degrees, which facilitates ink level control. Eighth, a scraper rod is positioned across the anilox roller via brackets at both ends of the anilox roller, with the scraper end face of the corresponding scraper module positioned close to the inner wall of the anilox roller. The scraper rod is then adjusted so that its core is flush with the center of the anilox roller.
