Embodiment 1

[0043] A flexible printing plate sticking device, refer to figure 1 , including a frame 1, on which a rotating assembly 2 for installing a printing roller 3 is arranged, when the printing roller 3 is mounted on the frame 1 through the rotating assembly 2, the axis of the printing roller 3 is set horizontally. A platform 4 for placing a flexographic printing plate 6 is provided on the frame 1, and the platform 4 is horizontally arranged at a position flush with the upper part of the printing roller 3, and an alignment ruler 5 is arranged parallel to the top of the platform 4, and the alignment ruler 5 slides horizontally Attached to rack 1. During use, the flexographic printing plate 6 is first placed on the platform 4, then the position of the flexographic printing plate 6 relative to the printing roller 3 can be adjusted, so that the alignment ruler 5 will measure the position of the printing printing plate on the platform 4, and by aligning The sliding of the ruler 5 measu...

Embodiment 2

[0052] A flexible printing plate sticking device, refer to Figure 6 The difference with Embodiment 1 is that the positioning assembly 8 includes a positioning screw 85, the length direction of the positioning screw 85 is arranged parallel to the guide rod 73, and the positioning screw 85 penetrates through the connecting piece 76 and is threadedly connected with the connecting piece 76, and the positioning screw 85 The lower end is used to abut against the beam body 74 . When the positioning screw 85 is rotated, the lower pressing roller 72 can move up or down, so that the lower pressing roller 72 can be positioned at a position away from the printing roller 3, and when the lower end of the positioning screw 85 breaks away from the beam body 74, the lower pressing roller 72 It can keep in contact with the printing roller 3 .

Abstract

The invention relates to the technical field of printing, in particular to a flexible printing plate pasting device. The flexible printing plate pasting device comprises a rack used for rotationally installing a printing roller. A movable platform is arranged on the rack. When the upper surface of the platform is flush with the upper portion of the printing roller, the platform is used for containing a flexible printing plate. An alignment ruler is in sliding connection to the rack and is parallel to the platform, and the sliding direction of the alignment ruler relative to the rack is perpendicular to the axis of the printing roller. A gap is formed in the position, corresponding to the upper portion of the printing roller, of the platform. The flexible printing plate pasting device has the effect that workers can conveniently and rapidly align and paste the flexible printing plate.

Description

technical field [0001] The present application relates to a technical field of printing, in particular to a flexographic printing plate sticking device and method. Background technique [0002] Printing is to transfer the information to be printed to the paper through the printing plate. According to different printing plates and embossing methods, printing machines can be divided into flat press flat presses, flat press round presses, direct round press round presses, and indirect round press round presses, among which round press round presses The printing machine installs the flexible printing plate on the peripheral wall of the cylindrical printing roller, and prints on the paper by driving the flexible printing plate through the rotation of the printing roller. refer to Figure 7 , The flexographic printing plate 6 includes a plate body 64 and a non-stick paper 63 attached to one side of the plate body 64, and glue is coated between the plate body 64 and the non-stick ...
