[0025] This specific embodiment is a printing head of a vertical printing press, and its structural diagram is as follows Figure 1-Figure 4 As shown, the printing head of the vertical printing press is installed on the workbench 1, and the printing head of the vertical printing press includes a longitudinal lifting seat 2, a first vertical plate 3, a second vertical plate 4, a lifting block 7 and a connecting rod 8. Cylinders are provided at both ends of the longitudinal lifting seat 2. The first vertical plate 3 is fixedly mounted on one end of the longitudinal lifting seat 2, and the second vertical plate 4 is fixedly mounted on the other end of the longitudinal lifting seat 2. An upper fixed plate 5 and a lower fixed plate 6 are fixedly mounted on the side where the first vertical plate 3 and the second vertical plate 4 are close to each other. The lifting block 7 is arranged between the upper fixed plate 5 and the lower fixed plate 6. The cylinder is used to drive the lifting block 7 to move up and down. The connecting rod 8 is fixedly mounted on the lifting block 7. A brush plate seat 9 is fixedly mounted on the bottom end of the connecting rod 8, and a brush plate 10 is fixedly mounted on the brush plate seat 9.

[0026] By setting the cylinder, the brush plate seat 9 and the brush plate 10 can be driven to rise and fall. At the same time, by setting the two cylinders at the front and rear ends of the longitudinal lifting seat 2 respectively, the pressure can be balanced, thereby avoiding missing prints and uneven ink thickness when scraping ink.

[0027] The cylinder is fixedly mounted on the top of the upper fixed plate 5. A through hole is provided on the upper fixed plate 5 for the telescopic end of the cylinder to pass through. The telescopic end of the cylinder passes through the through hole and extends to the bottom of the upper fixed plate 5. The telescopic end of the cylinder is fixedly connected to a connecting block, which is fixedly connected to the lifting block 7.

[0028] Under the action of the through hole, the telescopic rod of the cylinder is able to extend and retract, and at the same time, under the action of the connecting block, the cylinder can drive the lifting block 7 to move up and down.

[0029] A guide hole is provided on the lifting block 7, and a guide rod 11 adapted to the guide hole is fixedly connected to the lower surface of the upper fixed plate 5. The bottom end of the guide rod 11 passes through the guide hole and is fixedly connected to the upper surface of the lower fixed plate 6;

[0030] When the cylinder drives the lifting block 7 to rise and fall, the lifting block 7 can slide on the guide rod 11 through the guide hole. With the cooperation of the guide rod 11 and the guide hole, it can guide the lifting of the lifting block 7 and prevent the lifting block 7 from being offset during the lifting process, thereby guiding the lifting of the connecting rod 8, the brush plate seat 9 and the brush plate 10. At the same time, due to the coordinated setting of the upper fixed plate 5 and the lower fixed plate 6, the lifting block 7 can be prevented from separating from the guide rod 11.

[0031] The first vertical plate 3 is mounted on the transverse motion mechanism 16. The transverse motion mechanism 16 has been disclosed in Patent Publication No. CN213767690U, a built-in high-efficiency fully automatic CCD registration printing device. The installation method of the first vertical plate 3 and the transverse motion principle are both disclosed in the prior art and will not be described in detail here.

[0032] The top of the longitudinal lifting seat 2 is fixedly connected with a sliding block 12, and the side of the sliding block 12 away from the longitudinal lifting seat 2 is slidably connected with a slide rail 13, and the slide rail 13 is fixedly installed on the U-shaped frame 14;

[0033] The lateral movement mechanism 16 enables the first vertical plate 3 to drive the longitudinal lifting seat 2 fixed to it to move horizontally when it moves horizontally. The longitudinal lifting seat 2 can drive the sliding block 12 to slide on the slide rail 13 when it moves horizontally. With the coordinated setting of the sliding block 12 and the slide rail 13, it can guide the movement of the longitudinal lifting seat 2, thereby achieving a guiding effect on the various structures installed on the longitudinal lifting seat 2, making the brush plate seat 9 and the brush plate 10 more stable and firm when moving.

[0034] Both ends of the U-shaped frame 14 are fixedly mounted on the material fixing lifting connecting arm 15, and the material fixing lifting connecting arm 15 is mounted on the transverse motion mechanism 16. The material fixing lifting connecting arm 15 has been disclosed in the patent publication number CN213767690U, a built-in high-efficiency fully automatic CCD registration printing device. The material fixing lifting connecting arm 15 is a prior art and will not be described in detail here.

[0035] A brush head lifting mechanism is fixedly provided on the workbench 1 for driving the brush plate 10 and the material fixed lifting connecting arm 15 to rise and fall. The brush head lifting mechanism and the principle of the brush head lifting mechanism driving the brush plate 10 and the material fixed lifting connecting arm 15 to rise and fall have been disclosed in patent publication number CN213767690U, a built-in high-efficiency fully automatic CCD registration printing equipment. They are all existing technologies and will not be repeated here.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
