[0002] Generally, the printing plate is a flat aluminum plate with the pattern to be printed on it. This flat plate cannot be fixed on the printing press. Therefore, before fixing, the printing plate needs to be bent and cut. After bending and cutting, it can be directly and securely fixed to the printing press. The accuracy of bending and cutting directly affects the fixed position and angle, which in turn affects the final printing accuracy, that is, the printing quality.

[0003] In the existing bending and cutting process, the CDD lens and the manual operation adjustment block are used to align the cross calibration line on the printed plate with the cross virtual line on the display, which is cumbersome and inefficient. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a semi-automatic alignment mechanism for printing plates which can automatically separate waste materials and finished products and collect the finished products together, thereby greatly reducing labor costs and improving production efficiency.

The bending plate is rotatably installed on the turning frame, and the outward end surface of the folding plate is set as an inwardly inclined bending surface.

Figure 2 As shown, both sides of the end surface of the printed plate 2 are respectively provided with cross calibration lines 21 arranged in sequence, an adjusting push block 8 driven by a servo motor 7 to extend and retract is installed on one side of the folding plate 4, and a clamping spring 9 corresponding to the adjusting push block 8 is installed on the other side of the folding plate 4. One end of the clamping spring 9 is welded in a groove of a spring seat 10, and the other end of the clamping spring 9 is provided with a push plate 91. The adjusting push block 8 has two positions arranged between the folding plate 4 and the support plate 3. The push plate 91 contacts the side of the printed plate 2 on the support plate 3. The left and right positions of the printed plate 2 can be adjusted by adjusting the adjusting push block, so that the CDD lens 5 is calibrated with the cross calibration line 21 on the printed plate 2 and the printed plate 2 is positioned. The servo motor 7 is connected to the processor, so that the processor can be more aware of the calibration of the CDD lens 5 and drive the adjusting block to push the printed plate 2 to adjust its position through the servo motor 7.

[0018] Specific as Figure 1 , Figure 5 As shown, a guide rod 20 and an optical axis 30 are mounted above the support plate 3, a slide 40 is sleeved on the guide rod 20 and the optical axis 30 and slides, a tension sleeve 50 is arranged on the slide 40, and the tension sleeve 50 is fixed on the optical axis 30 by a tension bolt, and a CDD lens 5 is installed on the slide 40. In this way, the tension bolt is loosened, and the CDD lens 5 slides on the optical axis to align it with the horizontal lines of the cross lines on both sides of the printing plate, and after alignment, the tension bolt is locked.

[0019] Specific as Figure 2 , Figure 3 As shown, an adjustment seat 81 is provided corresponding to the adjustment push block 8, and the adjustment seat 81 is on the base 1. The servo motor 7 is installed at one end of the adjustment seat 81, and a square guide groove 82 is provided at the other end of the adjustment seat 81. The adjustment push block 8 is adapted to the square guide groove 82, and an internal threaded tube 83 is provided on one side of the adjustment push block 8. A threaded rod 71 is provided on the output shaft of the servo motor 7, and the threaded rod 71 is threadedly connected with the internal threaded tube 83, so that the servo motor 7 can drive the adjustment push block 8 to extend and retract along the opening of the square guide groove, so as to achieve the function of automatically adjusting the left and right positions of the plate.

[0020] A turning frame 50 is installed at the end of the folding plate 4, and a pressing plate 501 and a swingable bending plate 502 are installed on the turning frame 50. The bending plate is rotatably installed on the turning frame 50. The outward end surface of the folding plate 4 is set as an inwardly inclined bending surface 41. A movable cutting and punching component 60 is arranged on one of the pressing plates 501. Figure 5 As shown, the structure of the cutting and punching assembly 60 includes a base body and a cutting knife 80 connected to the pressure plate. The base body 100 is rotatably connected with a lever pressure rod 70. The cutting knife 80 includes a cylindrical rod and a square-shaped cutter head connected to the end of the rod. A guide hole matching the cutting knife 80 is provided on the base body. The rod of the cutting knife 80 extends out of the guide hole. The movable end of the lever pressure rod 70 presses down to contact the rod of the cutting knife 80 to drive the square-shaped cutter head of the cutting knife 80 to extend along the guide hole and punch a cutting square opening 90 (the cutting square opening 90 is designed on a bottom plate) at the front position of the outlet end. The brush plate is placed between the cutting square opening 90 and the guide hole outlet. During operation, the flip frame flips so that the pressure plate presses the printing plate, and then the bending plate rotates and presses the edge of the printing plate toward the bending surface for bending. Finally, the printing plate 2 is punched by the cutting and punching assembly, thereby achieving the technical effect of assisting the printing plate in precise bending and cutting. The cutting and punching assembly drives the cutting knife 80 to punch the printing plate 2 through the lever pressure rod 70. After punching, the printing plate 2 has a square positioning hole, thereby ensuring that the printing plate 2 is more accurately and reliably installed on the printing machine.

[0021] By adopting the above technical solution, after the CDD lens 5 and the display 6 are designed as an integral whole, the operator can intuitively see the calibration status of the crosshairs on the printing plate 2. By adjusting the CDD lens 5, it can be aligned with the horizontal line of the crosshairs first, and then the processor controls the servo motor 7 to drive the adjustment block to push the printing plate 2 to adjust the left and right positions, so that it can be quickly aligned with the longitudinal line of the crosshairs. This greatly improves the positioning efficiency of the printing plate 2, facilitates subsequent accurate bending and cutting, and thus the printing plate 2 can be more accurately positioned on the printing press, so that the accuracy of the printed pattern is higher.
