Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A paper correction device for a UV printing machine includes a positioning frame 1 and a correction plate 3. A flexible correction component is provided on the inner side of the positioning frame 1, and the flexible correction component is used to flexibly adjust and correct the deviation. An adjustment component is provided on the front side of the positioning frame 1, and the adjustment component is used to flexibly adjust the position to adapt to different sizes of paper.

[0025] The flexible correction component includes a high-precision push rod 202, and a piston rod 203 is provided at the output end of the high-precision push rod 202. A lifting plate 204 is installed on the top of the piston rod 203. The flexible correction component includes two sets of limiting sliders 301, and the limiting sliders 301 are located inside the positioning frame 1. Two sets of limiting plates 205 are respectively installed on the top of the limiting sliders 301 and on both sides of the lifting plate 204. A drive rod 2 is provided between the limiting plates 205.

[0026] The adjustment assembly includes a stabilizing slider 401, and a movable bracket 403 is mounted on the front of the stabilizing slider 401. An adjustment knob 502 is provided on the inner side of the back of the movable bracket 403, and an adjustment screw 503 is mounted on the back of the adjustment knob 502. A guide frame 504 is provided on the outer side of the adjustment screw 503, and an anti-slip plate 5 is mounted on the back of the guide frame 504. The stabilizing slider 401 is mounted on the back of the movable bracket 403, and the stabilizing slider 401 is located outside the guide frame 504.

[0027] Through the above technical solution, the high-precision push rod 202 can drive the piston rod 203 to adjust the height. The adjustment process is that the lifting plate 204 will rise and pull the drive rod 2, thereby driving the end limit slider 301 to slide along the inner side of the limit slide groove 102. When sliding, the range of the bottom correction plate 3 will be adjusted, thereby clamping the paper. The correction process can be performed by quick clamping, avoiding the problem of offset during printing.

[0028] With the above technical solution, the lateral adjustment can be made along the limiting slide groove 102 by using the stabilizing slider 401. During the adjustment process, after judging the position by the scale line on the top of the positioning frame 1, rotating the adjustment knob 502 can drive the adjustment screw 503 to rotate, thereby driving the guide frame 504 and the anti-slip plate 5 to contact the back side of the inner side of the stabilizing slide groove 104 for locking. The adjustment component can be used to flexibly adapt to different sizes of paper for adjustment. The movable bracket 403 and the reflective photoelectric sensor 4 are fixed by bolts.

[0029] Specifically, fixed brackets 101 are installed at both ends of the positioning frame 1, and the bottom of the fixed brackets 101 is connected to the top of the UV printing machine conveying structure bracket by bolts. Two sets of stabilizing grooves 104 are opened on the front of the positioning frame 1, and the stabilizing grooves 104 are located on the outside of the stabilizing slider 401. Two sets of arc-shaped grooves are opened at the top and bottom of the inner side of the stabilizing grooves 104 respectively.

[0030] Through the above technical solution, the fixed bracket 101 can be fixed to the conveying structure of the printing machine by bolts, and the stabilizing slide 104 can provide a limit for the stabilizing slider 401 and assist in sliding adjustment. The arc groove is used to splice with the limiting slide column 402. The top of the positioning frame 1 is set with scale lines, and the position of the movable bracket 403 can be easily observed by setting a pointer on the movable bracket 403.

[0031] Specifically, two sets of limiting slide grooves 102 are provided on the inner side of the positioning frame 1, and the limiting slide grooves 102 are located on the outer side of the limiting slider 301. A limiting post 103 is installed in the middle of the limiting slide grooves 102, and the limiting post 103 is located in the middle of the limiting slider 301.

[0032] Through the above technical solution, the limiting groove 102, together with the limiting post 103, can restrict the limiting slider 301, and the smoothness of sliding can be increased by adding lubricating oil.

[0033] Specifically, a driver 201 is provided on the front of the lower end of the high-precision push rod 202, and the driver 201 is located at the top of the positioning frame 1. A limit shaft is provided at the connection between the limit plate 205 and the drive rod 2.

[0034] With the above technical solution, when the driver 201 is powered on, it can control the gearbox using the internal motor, and finally drive the internal screw to rotate. The rotation can control the piston rod 203 for adjustment, and the limit shaft can assist the drive rod 2 in flipping adjustment.

[0035] Specifically, the inner side of the limiting slider 301 is provided with a through hole 302, and the through hole 302 is located on the outer side of the limiting post 103. The correction plate 3 is located at the bottom of the limiting slider 301 on the side close to the high-precision push rod 202, and the bottom of the correction plate 3 is provided with a splicing groove 303, which is connected to the outer side of the printing press transmission rotary roller.

[0036] Through the above technical solution, the through hole 302 can slide and adjust along the limiting post 103, and the splicing groove 303 can be spliced ​​with the support roller of the conveying structure at the interval position. Contact should be avoided, and the paper can be corrected by clamping.

[0037] Specifically, a reflective photoelectric sensor 4 is installed on the inner side of the front of the movable bracket 403, and a connecting wire 404 is installed at the input end of the reflective photoelectric sensor 4. Two sets of limiting slide posts 402 are installed at the top and bottom of the stabilizing slider 401, and the limiting slide posts 402 are embedded in the inner side of the arc-shaped groove.

[0038] With the above technical solution, when using the reflective photoelectric sensor 4, a reflector needs to be set at the bottom. By working together, it is possible to determine whether the paper has shifted, and then control the correction device to perform correction processing. Before use, the reflective photoelectric sensor 4 and the high-precision push rod 202 need to be connected to the external controller and display, and the controller is used for control and adjustment.

[0039] Specifically, the adjustment knob 502 is equipped with a combination bearing 501 on both sides, and the combination bearing 501 is located on the inner side of the back of the movable bracket 403.

[0040] Through the above technical solution, the combined bearing 501 can assist the adjustment knob 502 in rotating.

[0041] In use, the high-precision push rod 202 is first controlled by the controller to adjust the height of the lifting plate 204. During the ascent, the drive rod 2 pulls the limit slider 301 to slide along the inner side of the limit groove 102, thereby driving the bottom correction plate 3 to clamp and correct the paper on the inner side. When adjustment is required, the stabilizing slider 401 can be controlled to slide along the inner side of the stabilizing groove 104. The position is determined by the pointer and scale. Finally, the adjusting knob 502 drives the adjusting screw 503 to rotate, thereby using the threaded structure to push the anti-slip plate 5 to squeeze and stabilize.
