[0032] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it is worth specifically explaining that the adjustment component 3 includes a plurality of symmetrically distributed electric push rods 31 fixed to the inner side wall of the frame 1, a plurality of symmetrically distributed channels 32 are opened on one side wall of the frame 1, the electric push rod 31 is located inside the channel 32, a support frame 33 is fixed to the top side wall of the frame 1, and two symmetrically distributed support plates 34 are slidably connected to the inner side wall of the support frame 33, a connecting plate 35 is fixed to one side wall of the support plate 34, a slide groove 36 is opened on one side wall of the support frame 33, the connecting plate 35 is slidably connected to the inside of the slide groove 36, and the output end of the electric push rod 31 is fixed to the bottom side wall of the connecting plate 35; a transmission shaft 37, the transmission shaft 37 is rotatably connected to the side walls of one side of the two support plates 34, a servo motor b38 is fixed to the side wall of one side of one of the support plates 34, and one end of the servo motor b38 It is coaxially fixed with one end of the transmission shaft 37, and two symmetrically distributed connecting seats 39 are fastened and sleeved on the outer surface of the transmission shaft 37.

Not only is the structure simple and compact, but the device adopts the adjustment component 3 to replace the work of the staff, and the angle flipping accuracy of the printing plate is higher, which further improves the printing efficiency of the printing plate, thereby ensuring the quality of the printing plate.

[0033] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that the positioning component 8 includes two mounting plates 81, and the two mounting plates 81 are symmetrically distributed and fixed on the top side wall of the carrying frame 2, and an additional plate 82 is fixed to one side wall of the mounting plate 81, and a driving motor 83 is fixed to one side wall of the additional plate 82, and two symmetrically distributed bearing seats 84 are fixed to one side wall of the mounting plate 81, and a bidirectional threaded rod 85 is connected to the two bearing seats 84 for common rotation; a plurality of through grooves 86, and a plurality of through grooves 86 are symmetrically distributed and opened on one side wall of the two mounting plates 81, and a positioning plate 87 is slidably connected inside the through grooves 86, and the positioning plate 87 is threadedly connected to the external thread of the bidirectional threaded rod 85, and the positioning plate 87 is located directly above the conveyor belt 5.

[0034] This solution has the following working process: when it is necessary to perform eight-color printing on the printed product, first place the printed plate on the conveyor belt 5, and drive it synchronously through two driving motors 83, so that the bidirectional threaded rod 85 rotates synchronously, and the threaded transmission effect between the bidirectional threaded rod 85 and the positioning plate 87 is used to cause the positioning plate 87 to move along the through groove 86, and the positioning plate 87 moves toward the printed plate until the positioning of the printed plate is completed. When the height position of the printed plate needs to be adjusted, the operation control of the wireless controller 10 is used to drive multiple electric push rods 31 synchronously, drive the connecting plate 35 to move synchronously, thereby driving the support plate 34 to move along the support frame 33 after being subjected to force, so as to achieve the purpose of adjusting the height of the printed plate. When the angular position of the printed plate needs to be adjusted, the servo motor a7 is used to drive the transmission shaft 37 to rotate synchronously, drive the connecting seat 39 to operate, thereby driving the angle of the printed plate to be adjusted, so as to achieve the purpose of adjusting the angle of the printed plate.

[0035] According to the above working process, it can be known that: through the setting of the adjustment component 3, the height and angle position of the printing plate can be adjusted according to the printing work requirements, so as to meet the different printing work requirements, with a wide range of applications and high flexibility, and not only the structure is simple and compact, but also the device adopts the adjustment component 3 to replace the work of the staff, and the angle flipping accuracy of the printing plate is higher, further improving the printing efficiency of the printing plate, thereby ensuring the quality of the printing plate, and through the setting of the positioning component 8, the printing plate placed on the top surface of the conveyor belt 5 can be clamped and positioned, thereby ensuring the stability of the printing plate during printing processing, preventing the displacement of the printing plate from affecting the final printing effect, and can be used for positioning printing plates of different sizes, not only flexible and convenient adjustment, but also applicable to a wide range of specifications, effectively improving utilization.

[0036] Further as Figure 1 As shown, it is worth explaining in detail that a rubber plate 9 is fixed to the side wall of one side of the positioning plate 87, and the side wall of one side of the rubber plate 9 is arranged with a chamfered inclined surface. Through the elastic effect of the rubber plate 9 itself, a pre-tightening effect is achieved when the printed plate is clamped and positioned, and the printed plate is effectively prevented from falling due to poor positioning effect, and the clamping and positioning effect of the printed plate is better.

[0037] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that a plurality of anti-skid grooves 11 are arranged on the outer surface of the conveyor belt 5 and are distributed at equal intervals. The projection area of ​​the frame 1 is larger than the projection area of ​​the conveyor belt 5.

The wireless controller 10 is electrically connected to the multiple electric push rods 31. Through the setting of the wireless controller 10, it is convenient for the staff to control multiple electric push rods 31 for synchronous driving at the same time, which is simple to operate and has high stability.

Through the setting of the connecting plate 35, the connection stability between the connecting plate 35 and the supporting plate 34 can be greatly improved to prevent shaking during transmission.

[0040] In summary: the elastic effect of the rubber plate 9 itself can achieve a pre-tightening effect when clamping and positioning the printed plate, effectively preventing the printed plate from falling due to poor positioning, and having a good clamping and positioning effect on the printed plate. The anti-slip groove 11 can be set to achieve an anti-slip effect on the conveying of the printed plate, avoiding slippage when adjusting the position of the printed plate. The wireless controller 10 can facilitate the staff to control multiple electric push rods 31 for synchronous driving at the same time, which is simple to operate and has high stability. The connection stability between the connecting plate 35 and the support plate 34 can be greatly improved through the setting of the connecting plate 35 to prevent shaking during transmission.
