Description

Technical Field

[0001] This invention relates to the field of printing production technology, specifically to an eight-color printing press with uniform ink output. Background Technology

[0002] As an important part of the modern printing industry, the eight-color printing press is leading the innovation of printing technology with its high precision, high efficiency and rich color expression. By precisely controlling the supply and distribution of ink, the eight-color printing press can ensure that each color ink adheres evenly and accurately to the substrate, thereby achieving high-precision printing results. Moreover, it can use eight different colors of ink for printing at the same time, providing designers and printers with a wider creative space and meeting the market's demand for colorful and personalized printed products.

[0003] When the printing press sprays ink, the high viscosity of the ink can cause it to adhere to the nozzle and form residue. This residue will gradually accumulate, affecting the uniform distribution of ink during subsequent printing, resulting in uneven color in the printed product and affecting the visual effect. Furthermore, the residual ink will gradually solidify, causing the nozzle to become clogged, increasing the equipment failure rate and affecting the production schedule.

[0004] Therefore, this invention proposes an eight-color printing press with uniform ink output to compensate for and improve the shortcomings of the prior art. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages:

It can also squeeze the ink to prevent it from drying out, so as to maintain the fluidity and printing performance of the ink.

[0019] 3. When the fixed strip is driven to slide left and right by the third gear, the scraper can move against the surface of the ink, so that the ink can be evenly distributed on the outer surface of the roller, improving the clarity of roller printing. As the amount of ink increases, the scraper can gradually move upward, so as to adapt to the height of the ink and smooth the ink, avoiding waste and printing defects caused by ink accumulation.

[0020] 4. When the back side of the scraper is attached to the outer surface of the roller, the ink on the outer surface of the roller can be scraped off, thereby shortening the cleaning time of the ink on the roller surface. The scraped ink can also be collected into the collection box, which can not only reduce unnecessary waste, but also improve resource utilization. Attached Figure Description

The outer surfaces of the first gear 1101 mesh with the inner side of a conveyor belt 19, which in turn drives the first gear 1101 to rotate. A rotating rod 112 is fixedly connected to the top of each of the first gears 1101, and a second gear 113 is fixedly connected to the top of each of the rotating rods 112. The first threaded sleeve 110 rotates on the outer surface of the first screw 111, causing the rotating rod 112 and the second gear 113 to move upward. A second screw 115 is fixedly connected to the bottom of the inner side of the ink cartridge 12, and a rotating component 114 is threadedly connected to the outer surface of each of the second screws 115. The outer surfaces of the second gears 113 mesh with the bottom of the rotating component 114. In conjunction with the second gear 113, the rotating component 114 is driven to move downward and rotate. The upper surface of the rotating component 114 is fixedly connected with a torsion spring 116. The top of the torsion spring 116 is fixedly connected to the bottom of the inner side of the ink cartridge 12. The torsion spring 116 is used to drive the rotating component 114 to reset and rotate. When the transmission wheel 18 is driven to rotate by the motor 17, the second gear 113 can move upward and engage with the rotating component 114, causing the rotating component 114 to move downward and rotate to clear the residual ink in the ink outlet hole of the ink cartridge 12. This can effectively prevent the ink from accumulating in the ink outlet hole of the ink cartridge 12, so that the ink is evenly distributed during the printing process, avoiding uneven color or blurry printing caused by ink accumulation, thereby improving the overall quality of the printed products.

[0041] refer to Figure 6 and Figure 7 As shown, an eight-color printing press with uniform ink output includes an electric slide rail 2 fixedly connected to the upper surface of the front side of the printing device 1. A rack 22 is fixedly connected to the front side of the electric slide rail 2. A sliding block 21 is slidably connected to the lower surface of the top of the electric slide rail 2, allowing it to slide left and right on the lower surface of the top of the electric slide rail 2. A third gear 23 is rotatably connected to the bottom of the sliding block 21, driving the third gear 23 to move. A second threaded sleeve 24 is fixedly connected to the bottom of the third gear 23, driving the second threaded sleeve 24 to move. The outer surface of the third gear 23 meshes with the rear side of the rack 22. When the third gear 23 moves behind the rack 22, it drives the third gear 23 to rotate. The third gear 23 is used to drive... The second threaded sleeve 24 rotates simultaneously. The internal thread of the second threaded sleeve 24 is connected to a bidirectional screw 25. When the second threaded sleeve 24 rotates, it drives the bidirectional screw 25 to move up and down. A fixing member 26 is fixedly connected to the outer surface of the bidirectional screw 25. When the bidirectional screw 25 moves, it drives the fixing member 26 to move simultaneously. A limiting rod 27 is slidably connected to the inner side of the fixing member 26. The front side of the top of the limiting rod 27 is fixedly connected to the rear side of the sliding block 21. The limiting rod 27 is used to guide the movement of the fixing member 26. By moving up and down on the ink surface through the bottom of the fixing member 26, it can prevent the ink from accumulating too much in the same area, so that the ink can be more evenly covered on the upper surface of the roller 14, and the color of the printed matter can be kept consistent and uniform.

[0042] refer to Figures 8 to 11As shown, an eight-color printing press with uniform ink output has a fixing bar 3 fixedly connected to the outer surface of a limiting rod 27. The limiting rod 27 is used to drive the fixing bar 3 to move. The front end of the fixing bar 3 is rotatably connected to the outer surface of a second threaded sleeve 24. The bottom of the fixing bar 3 is symmetrically fixedly connected to a limiting rod 31. The fixing bar 3 is used to drive the limiting rod 31 to move. A sliding frame 32 is slidably connected between the sides of the limiting rods 31 that are close to each other. Extrusion rods 33 are fixedly connected to both sides of the sliding frame 32. The limiting rods 31 are used to drive the sliding frame 32 to move with the extrusion rods 33. The rod 33 moves, and a scraper 34 is fixedly connected to the lower surface of the left end of the sliding frame 32. The sliding frame 32 is used to drive the scraper 34 to move. The scraper 34 is used to scrape the ink on the upper surface of the front side of the printing device 1. An extrusion frame 35 is symmetrically fixedly connected to the upper surface of the front side of the printing device 1. The side of the extrusion frame 35 that is close to each other is inclined. The side of the extrusion rod 33 that is far away from each other is in extrusion fit with the inclined side of the extrusion frame 35 that is close to each other. The extrusion frame 35 is used to drive the extrusion rod 33 to move upward. The two sides of the upper surface of the sliding frame 32 are symmetrically fixed. The device is connected to a telescopic component 36, with a pressing block 37 fixedly connected to each side of the telescopic component 36 that is far apart from each other. The pressing rod 33 is used to drive the telescopic component 36 and the pressing block 37 to move upward through the sliding frame 32. The limiting rod 31 has multiple square inclined slots on the side that is close to each other in a straight line. The square inclined slots symmetrically opened on the limiting rod 31 engage with the side of the pressing block 37 that is far apart from each other. When the pressing block 37 moves upward, it engages in the square slots of the limiting rod 31. The side that is close to each other of the pressing block 37 is fixedly connected to a return spring 38. The side that is close to each other of the return spring 38 is fixedly connected to both sides of the top of the sliding frame 32. The return spring 38 is used to drive the pressing block 37 to return to its original position. When the fixing strip 3 slides left and right through the third gear 23, the scraper 34 can move against the surface of the ink, so that the ink can be evenly distributed on the outer surface of the roller 14, improving the clarity of the printing on the roller 14. As the amount of ink increases, the scraper 34 can gradually move upward, so as to adapt to the height of the ink and smooth the ink, avoiding waste and printing defects caused by ink accumulation.

[0043] refer to Figures 12 to 15As shown, an eight-color printing press with uniform ink output has a winding device 4 symmetrically fixedly connected to the upper surface of a sliding rod 16. Each winding device 4 has a pull rope 41 fixedly connected to its bottom. The outer surfaces of the pull ropes 41 pass through the upper surface of the sliding rod 16, and the winding device 4 is used to wind and unwind the pull ropes 41. A doctor blade 42 is fixedly connected to the bottom ends of the pull ropes 41, and the pull ropes 41 drive the doctor blade 42 to move up and down. The rear side of the doctor blade 42 is pressed against the outer surface of a roller 14, and the doctor blade 42 is used to scrape ink off the outer surface of the roller 14. A pin 45 is engaged with the lower surface of the doctor blade 42, and a collection box 43 is engaged with the outer surface of the pin 45. The pin 45 connects the doctor blade 42 to the collection box 43, which is used to collect the ink scraped by the doctor blade 42. Blocks 44 are fixedly connected to the front sides of both ends of the collection box 43. The upper side of the front side of the roller 14... A blocking box 46 is symmetrically and fixedly connected to the surface. The outer surface of the blocking block 44 is engaged with the inner side of the blocking box 46. The outer surface of the blocking block 44 is used to insert into the interior of the blocking box 46. Telescopic rollers 47 are fixedly connected to the inner side of the blocking box 46. The front side of the telescopic roller 47 is pressed against the outer surface of the blocking block 44. A storage spring 48 is fixedly wound around the outer surface of the moving end of the telescopic roller 47. The rear end of the storage spring 48 is fixedly connected to the inner side of the blocking box 46. The storage spring 48 is used to drive the telescopic roller 47 to move forward. When the rear side of the scraper 42 is attached to the outer surface of the roller 14, the ink on the outer surface of the roller 14 can be scraped off, thereby shortening the cleaning time of the ink on the surface of the roller 14. The scraped ink can be collected into the collection box 43, which can not only reduce unnecessary waste, but also improve resource utilization.

[0044] The complete working principle and steps of the above embodiments are as follows:

[0045] refer to Figures 1 to 5 As shown, when the printing press is in its initial state, the motor 17 is in the off state, the outer surface of the second gear 113 has not yet engaged with the bottom of the rotating part 114, and the torsion spring 116 is in a naturally relaxed state.

[0046] When printing using this printing press, the operator first pours the ink to be printed onto the right side of the feed pipe 13. The ink inside the feed pipe 13 then flows into the ink cartridge 12. The ink inside the ink cartridge 12 flows from the outlet hole at the bottom of the ink cartridge 12 to the outer surface of the roller 14. As the ink flows out from the outlet hole at the bottom of the ink cartridge 12, its high viscosity causes it to adhere to the outlet hole. At this point, the operator can slide the sliding rod 16 backward between the guide members 15. When the motor 17 moves, the sliding rod 16 slides backward, which in turn drives the first threaded sleeve 110 to move via the first screw 111. The first threaded sleeve 110 then drives the second gear 113 to move via the rotating rod 112, causing the rotating rod 112 and the second gear 113 to be positioned at the bottom of the ink cartridge 12's outlet hole. At this time, the motor 17 is started, causing the output shaft of the motor 17 to drive the transmission wheel 18 to rotate. When the transmission wheel 18 rotates, it drives the three first gears 1101 to rotate simultaneously via the conveyor belt 19. When the first gears 1101 rotate, they drive the three first gears 1101 to rotate simultaneously. The first threaded sleeve 110 rotates on the outer surface of the first screw 111. As the first threaded sleeve 110 rotates, it gradually moves upward on the outer surface of the first screw 111. At this time, the first threaded sleeve 110 can drive the second gear 113 to move simultaneously via the rotating rod 112. When the second gear 113 moves upward and inserts into the ink cartridge 12's outlet hole, its outer surface can engage with the bottom of the rotating member 114. As the second gear 113 rotates, it drives the rotating member 114 to rotate simultaneously. The rotating member 114... When the outer surface of the two screws 115 rotates, it gradually moves downward. When the rotating part 114 moves downward, it can rotate the torsion spring 116 to the stored tension state. When the rotating part 114 rotates downward, it can squeeze the ink out of the ink outlet of the ink cartridge 12. When the rotating part 114 rotates, it can also scrape the inner wall of the ink outlet of the ink cartridge 12, thereby effectively preventing the ink from accumulating in the ink outlet of the ink cartridge 12 and making the ink evenly distributed during the printing process. When the rotating part 114 squeezes the solidified ink downward, it can prevent the solidified ink from returning to the inside of the ink cartridge 12.

[0047] As the first threaded sleeve 110 rotates on the outer surface of the first screw 111, the first threaded sleeve 110 can drive the second gear 113 to move downward through the rotating rod 112. When the second gear 113 moves downward, its outer surface will disengage from the bottom of the rotating member 114. At this time, the torsion spring 116, which is in a state of stored tension, will drive the rotating member 114 to reset and move on the outer surface of the second screw 115. As the rotating rod 112 drives the second gear 113 to slide out of the ink cartridge 12's outlet hole, the operator can push the sliding rod 16 forward, thereby causing the rotating rod 112 to drive the second gear 113 away from the ink cartridge 12's outlet hole, so that the ink cartridge 12 can normally deliver ink.

[0048] refer to Figure 6 and Figure 7 As shown, when the printing press is in its initial state, the electric slide rail 2 is in the closed state, and the outer surface of the third gear 23 meshes with the rear side of the left end of the rack 22.

[0049] As ink cartridge 12 delivers ink to the upper surface of the front of printing device 1, the electric slide rail 2 is activated, causing the sliding block 21 to move to the right. The sliding block 21 moves to the right, simultaneously moving the third gear 23. As the third gear 23 moves to the right, its outer surface meshes with the rear side of rack 22, causing it to rotate. This rotation of the third gear 23 causes the second threaded sleeve 24 to move to the right and rotate. The rotation of the second threaded sleeve 24 causes the bidirectional screw 25 to move to the right and slide up and down. The movement of the bidirectional screw 25 causes the fixing member 26 to slide on the outer surface of the limiting rod 27. The fixing member 26 moves up and down simultaneously with its rightward movement, and its bottom moves up and down on the ink surface. This prevents excessive ink accumulation in the same area, allowing the ink to cover the upper surface of the roller 14 more evenly, ensuring consistent color uniformity in the printed product. Furthermore, it squeezes the ink to prevent drying, maintaining its fluidity and printing performance.

[0050] refer to Figures 8 to 11 As shown, when the printing press is in its initial state, the left end of the left rack 22 is attached to the inclined surface at the bottom of the left extrusion frame 35, the extrusion blocks 37 on the opposite side are engaged in the square inclined groove at the bottom of the limiting rod 31 on the opposite side, and the return spring 38 is in a naturally relaxed state.

[0051] As the limiting rod 27 moves to the right, it drives the limiting rod 31 to move simultaneously via the fixing strip 3. The movement of the limiting rod 31 to the right drives the sliding frame 32 to move simultaneously. As the sliding frame 32 moves to the right, it drives the scraper 34 to move simultaneously. The scraper 34's movement to the right allows its bottom to adhere to the ink surface, thus ensuring even ink distribution on the outer surface of the roller 14 and improving printing clarity. Furthermore, the movement of the sliding frame 32 to the right also drives the pressing rods 33 on both sides of the sliding frame 32 to move simultaneously. At this time, the left end of the left pressing rod 33 disengages from the inclined surface of the left pressing frame 35. As the sliding frame 32 drives the pressing rods 33 on both sides to move to the right, the right end of the right pressing rod 33 adheres to the inclined surface of the right pressing frame 35 and moves the right pressing rod 33 upwards. The upward movement of the right pressing rod 33 drives the sliding frame 32 to move between the sides where the limiting rods 31 are close together. As the sliding frame 32 moves upward, the telescopic member 36 drives the extrusion block 37 to slide upward on the side of the limiting rod 31 that is close to each other. When the extrusion block 37 slides upward through the inclined groove at the bottom of the limiting rod 31, it causes the extrusion block 37 to press against the side that is close to each other. The extrusion block 37 presses the telescopic member 36 into a compressed state. As the extrusion block 37 continues to move upward, its inclined surface can coincide with another inclined groove of the limiting rod 31. At this time, the telescopic member 36, which is in a compressed state, can drive the extrusion block 37 to move away from each other, so that the inclined surface of the extrusion block 37 can be engaged in the other inclined groove of the limiting rod 31. When the sliding frame 32 moves upward, it also drives the scraper 34 to move simultaneously. This allows the height of the scraper 34 to be raised as the ink increases, so that the scraper 34 can smooth the ink at different heights, avoiding waste and printing defects caused by ink accumulation.

[0052] When it is necessary to lower the height of the scraper 34, the operator can move the extrusion block 37 to the side where they are close to each other. At this time, the inclined surface of the extrusion block 37 can disengage from the inclined groove of the limiting rod 31. The sliding frame 32 can then drive the extrusion block 37 to slide downward on the side where the limiting rod 31 is close to each other through the telescopic member 36. When the sliding frame 32 slides downward, it will drive the scraper 34 to slide simultaneously, so that the scraper 34 can return to its initial state.

[0053] refer to Figures 12 to 15As shown, when the equipment finishes printing on the product, the operator can push the sliding rod 16 backward. When the sliding rod 16 moves backward, it will cause the take-up reel 4 to move simultaneously. When the take-up reel 4 moves forward, it will cause the squeegee 42 to move simultaneously via the pull rope 41. After the squeegee 42 moves backward, the operator can activate the take-up reel 4, allowing it to loosen the pull rope 41. At this time, the squeegee 42 will move downward due to gravity, causing the pull rope 41 and the collection box 43 to move. When the collection box 43 reaches the bottom, the operator can push it forward, causing the collection box 43 to move the blocking block 44 forward. When the blocking block 44 moves forward, it can slide into the inside of the blocking box 46, and the front end of the blocking block 44 can squeeze the moving end of the telescopic roller 47, causing the moving end of the telescopic roller 47 to slide forward. When the moving end of the telescopic roller 47 slides forward, it can move the storage spring 48. When the collection box 43 is placed in the compressed state, the compressed spring 48 will drive the telescopic roller 47 to move forward. At this time, the moving end of the telescopic roller 47 can drive the collection box 43 to move forward through the blocking block 44. When the collection box 43 moves forward, it will drive the scraper 42 to move at the same time, so that the front side of the scraper 42 can be in contact with the outer surface of the roller 14. As the roller 14 rotates, the scraper 42 can scrape off the ink on the outer surface of the roller 14, thereby shortening the cleaning time of the ink on the surface of the roller 14. As the scraper 42 continues to scrape off the ink, the ink on the upper surface of the scraper 42 can flow into the interior of the collection box 43, making it convenient to collect the scraped ink. When the inside of the collection box 43 is full of ink, the staff can pull out the pin 45 to the right, so that the scraper 42 can be separated from the collection box 43, and the collection box 43 can be easily removed.

[0054] When the ink on the outer surface of the roller 14 is cleaned, and the telescopic roller 47 can completely push the blocking block 44 out of the blocking box 46, the operator can restart the rewinder 4 so that the rewinder 4 can rewind the pull rope 41. When the pull rope 41 moves upward, it will drive the scraper 42 and the collection box 43 to move simultaneously, so that the scraper 42 and the collection box 43 can return to their initial state.
