[0002] In existing aluminum plate printing processes, after the aluminum plate is positioned and transferred to the printing position, it needs to be fixed by suction cups to prevent it from sliding during printing and to improve printing quality. For example, an aluminum plate positioning printing device disclosed in patent application CN202111610563.9 (application date December 27, 2021) uses multiple suction cups to perform a vacuum operation on the suction cups to fix the aluminum plate. However, it has at least the following drawbacks: 1. The fixing mechanism has a complex structure, requiring the installation of multiple components such as support tubes and vacuum components; 2. Leakage may occur during the suction process, causing pressure pulse fluctuations in the pipeline. Adjacent suction cups may experience temporary pressure loss during the fluctuations, ultimately causing the aluminum plate to shift position. Summary of the Invention

Detailed Implementation

[0018] Specific Implementation Example 1: Please refer to Figures 1-8 An aluminum plate positioning and high-efficiency printing device includes a printing component 1, a transfer component 2, a positioning component 3, and a clamping component 4.

[0019] The printing assembly 1 is positioned above the positioning assembly 3. The printing assembly 1 includes a screen 11, a printing frame 12, a doctor blade 13, a return ink blade 14, a sliding seat 15, a slide rail 16, and a lifting plate 17. The slide rail 16 is laterally positioned on the side of the lifting plate 17. The other side of the lifting plate 17 is slidably connected to the output end of a lifting motor (not shown in the figure) to drive the lifting plate 17 to move up and down. One end face of the sliding seat 15 is slidably connected to the slide rail 16, and the sliding seat 15 extends away from the lifting plate 17. The doctor blade 13 is positioned behind the return ink blade 14. The upper ends of both the doctor blade 13 and the return ink blade 14 are embedded in the sliding seat 15. The upper ends of both the doctor blade 13 and the return ink blade 14 are connected to the output end of an independent doctor blade cylinder to drive the doctor blade 13 and / or the return ink blade 14 to move up and down, respectively.

[0020] There are two printing frames 12, symmetrically arranged on both sides of the lifting plate 17. The lower ends of the lifting plate 17 are fixedly connected to the upper ends of the printing frames 12. The printing frames 12 extend away from the lifting plate 17, in the same direction as the sliding seat 15. A screen 11 is positioned between the printing frames 12, with both ends fixedly connected to their corresponding printing frames 12. Both the doctor blade 13 and the return blade 14 have doctor blades at their lower ends, located above the screen 11. It should be noted that adding ink to the screen 11 using the doctor blade 13 and the return blade 14 for ink spreading and penetration is a conventional technique; the specific connection relationships and working principles are not detailed here. The length of the screen 11 is smaller than the length of the aluminum plate.

[0021] Positioning component 3 is located on the lower side of printing component 1. Positioning component 3 includes positioning platform 31, longitudinal positioning mechanism 32, and transverse positioning mechanism 33. Positioning platform 31 has a transfer groove 311, a longitudinal positioning groove 312, and a transverse positioning groove 313. Positioning platform 31 has a hollow structure. There are two transfer grooves 311, symmetrically located on both sides of positioning platform 31, with the grooves extending vertically downwards. The length of the transfer grooves 311 is along the longitudinal direction of positioning platform 31, so that the upper side of positioning platform 31 is connected to the front and rear end faces. There are also two longitudinal positioning grooves 312, located between the two transfer grooves 311, arranged sequentially. The longitudinal positioning grooves 312 are located on the upper side of positioning platform 31, with their length along the longitudinal direction of positioning platform 31. There are six transverse positioning grooves 313. Three transverse positioning grooves 313 are symmetrically arranged on the left and right sides of the upper side of the positioning platform 31. The transverse positioning grooves 313 are located on the outside of the transfer groove 311 (away from the longitudinal positioning groove 312). The length direction of the transverse positioning grooves 313 is along the transverse direction of the positioning platform 31.

[0022] There are two longitudinal positioning mechanisms 32, each correspondingly positioned on the lower side of the longitudinal positioning groove 312. Each longitudinal positioning mechanism 32 includes a longitudinal cylinder 321, a first positioning plate 322, a first lifting cylinder 323, and a first lifting rod 324. The output end of the longitudinal cylinder 321 is fixedly connected to one end face of the first positioning plate 322, which has an L-shaped structure. The first lifting cylinder 323 is positioned on the lower side of the first positioning plate 322. The lower end of the first lifting rod 324 is connected to the output end of the first lifting cylinder 323, enabling the first lifting rod 324 to move vertically and horizontally along the longitudinal direction of the positioning platform 31.

[0023] When positioning the aluminum plate, the first lifting rod 324 moves upward and extends out of the upper side of the positioning platform 31. The first lifting rods 324 located on the front and rear sides of the aluminum plate move towards each other to clamp the aluminum plate longitudinally.

[0024] There are two lateral positioning mechanisms 33, which are respectively set on the lower side of the lateral positioning slots 313 on both sides. The lateral positioning mechanism includes a lateral cylinder 331, a second positioning plate 332, a second lifting cylinder 333, and a second lifting rod 334. The output end of the lateral cylinder 331 is fixedly connected to one end face of the second positioning plate 332, which has an L-shaped structure. There are three second lifting cylinders 333, which are respectively set on the lower side of the second positioning plate 332. The positions of the second lifting cylinders 333 match the positions of the lateral positioning slots 313. Each second lifting cylinder 333 is correspondingly provided with a second lifting rod 334, and the lower end of the second lifting rod 334 is connected to the output end of the second lifting cylinder 333, so that the second lifting rod 334 has the ability to move up and down and move horizontally along the positioning platform 31.

[0025] The transfer assembly 2 is located on the upper side of the positioning platform 31. The transfer assembly 2 includes a conveyor belt 21 and a transfer cylinder 22. The conveyor belt 21 is embedded in the transfer groove 311. The transfer cylinder 22 is located on the outer side of the positioning platform 31, and its output end is fixedly connected to the side of the conveyor belt 21 to drive the conveyor belt 21 to move up and down. Specifically, the surface of the conveyor belt 21 is used to transfer aluminum plates. First, the conveyor belt 21 is lifted upward so that the conveying surface of the conveyor belt 21 is higher than the upper side of the positioning platform 31. After the aluminum plate is transported to the appropriate position, the conveying surface of the conveyor belt 21 is lowered to be flush with the upper side of the positioning platform 31. The positioning assembly 3 and the clamping assembly 4 position and clamp the aluminum plate, fixing it in the printing position. Then, the printing assembly 1 prints on the aluminum plate. After printing is completed, the conveyor belt 21 rises again to transfer the aluminum plate.

[0026] The clamping assembly 4 is disposed on the upper part of the second lifting rod 334. The clamping assembly 4 includes a baffle 42, a spring 43, an arc-shaped plate 44, and a slider 45. A clamping groove 41 is formed at the upper end of the second lifting rod 334. The clamping groove 41 is a stepped surface with its opening facing the aluminum plate. The baffle 42 is fixedly disposed on the upper side of the second lifting rod 334. A spring groove 47 is formed on the lower side of the baffle 42, and a vertical sliding groove 46 is formed on the lower side of the baffle 42, located on the side of the clamping groove 41. A protruding slider 45 is provided on the outer side of the arc-shaped plate 44, and the slider 45 is slidably connected to the sliding groove 46. The arc surface of the arc-shaped plate 44 faces downward. The spring 43 is disposed between the baffle 42 and the arc-shaped plate 44. The upper end of the spring 43 abuts against the spring groove 47, and the lower end of the spring 43 abuts against the upper side of the arc-shaped plate 44. When the spring 43 is not compressed, the lower side of the slider 45 abuts against the bottom surface of the groove 46.

[0027] Specifically, when the transverse positioning mechanism 33 positions the aluminum plate, the aluminum plate is located on the upper side of the positioning platform 31. The second lifting rod 334 rises to the lower side of the clamping groove 41 and is flush with the lower side of the aluminum plate. The upper side of the aluminum plate abuts against the lower side of the arc plate 44 to push the arc plate 44 upward until the side of the aluminum plate abuts against the side of the clamping groove 41.

[0028] Working principle: Aluminum plates are fed from the right side of conveyor belt 21. First, conveyor belt 21 is raised so that the conveying surface of conveyor belt 21 is higher than the upper side of positioning table 31. After the aluminum plate is conveyed to the left to the appropriate position, the conveying surface of conveyor belt 21 is lowered to be flush with the upper side of positioning table 31. Positioning component 3 and clamping component 4 position and clamp the aluminum plate. When the transverse positioning mechanism 33 positions the aluminum plate, the aluminum plate is located on the upper side of positioning table 32. The second lifting rod 334 rises to the lower side of clamping groove 41 and is flush with the lower side of aluminum plate. The upper side of aluminum plate abuts against the lower side of arc plate 44 to push arc plate 44 upward until the side of aluminum plate abuts against the side of clamping groove 41, so that aluminum plate is fixed in the printing position. Then, printing component 1 prints on aluminum plate. After printing is completed, conveyor belt 21 rises again to transport aluminum plate.

[0029] Specific Implementation Example 2: Please refer to Figure 9An aluminum plate positioning and high-efficiency printing device is described, similar to the first embodiment (details omitted here), but differing in that it also includes an edge-limiting component, comprising a limiting strip 51 and a limiting block 52. A limiting groove 53 is formed on the outer surface of the second lifting rod 334, located behind the clamping groove 41. The upper side of the limiting groove 53 is located below the baffle 42, and the lower side of the limiting groove 53 is located above the lower side of the clamping groove 41. The limiting block 52 is fixedly disposed at one end of the limiting strip 51, and the limiting block 52 is slidably connected to the limiting groove 53. When positioning the aluminum plate, the lower side of the limiting strip 51 abuts against the positioning table 31, and one end face of the limiting strip 51 abuts against the side of the aluminum plate, increasing the contact area between the aluminum plate and the transverse positioning mechanism 313 during positioning and enhancing positioning stability. Preferably, in this embodiment, limiting strips 51 are provided on both the left and right sides of each second lifting rod 334.

[0030] Specific Implementation Example 3: Please refer to Figure 10 This is an aluminum plate positioning and high-efficiency printing device. Similarities to Specific Embodiment 1 are not repeated here, but the difference lies in the inclusion of a magnetic suction assembly 6. The magnetic suction assembly 6 includes an upper magnetic suction plate 61, a lower magnetic suction plate 62, and a magnetic suction spring 63. The upper magnetic suction plate 61 has an arc-shaped structure and is fixedly arranged around the outside of the upper baffle 44. The spring 43 is located inside the upper magnetic suction plate 61, and the lower side of the upper magnetic suction plate 61 is located below the lower side of the upper baffle 44. The lower magnetic suction plate 62 is disposed below the clamping groove 41, and its shape and size match the shape and size of the lower side of the clamping groove 41. The magnetic suction spring 63 is disposed between the lower magnetic suction plates 62. The upper magnetic suction plate 61 and the lower magnetic suction plate 62 have opposite magnetic properties, thus attracting each other. The lower magnetic plate 62 and the clamping groove 41 are both provided with placement grooves. The upper and lower placement grooves are shafted together, and the upper and lower ends of the magnetic spring 63 are located in the placement grooves of the lower magnetic plate 62 and the clamping groove 41, respectively.

[0031] When the aluminum plate is positioned and clamped, when the upper side of the aluminum plate abuts against the lower side of the arc plate 44, the arc plate 44 is pushed upward until the side of the aluminum plate abuts against the side of the clamping groove 41; at this time, the upper side of the aluminum plate abuts against the lower side of the upper magnetic plate 61; the aluminum plate presses down the lower magnetic plate 62, and the lower side of the aluminum plate abuts against the upper side of the lower magnetic plate 62. The upper magnetic plate 61 and the lower magnetic plate 62 attract each other, clamping the aluminum plate from top to bottom.

[0032] It should be noted that the aluminum plate itself is not magnetic, but the aluminum plate itself is relatively thin. The magnetic lines of force of the upper magnetic suction plate 61 and the lower magnetic suction plate 62 located on the top and bottom sides are blocked by the aluminum plate, but they are not completely cut off. Some magnetic lines of force can still "pass through" the aluminum alloy plate to generate an attraction between the top and bottom, further improving the stability of the aluminum plate clamping and preventing the aluminum plate from vibrating up and down during the printing process.
