[0034] At this time, after the printing plate body is wrapped around the drum body 1, the tail end of the printing plate will be placed in the second clamping groove 3. At this time, the tightening nut 7 is manually rotated to make the tightening nut 7 drive the tightening shaft 4 to rotate, so as to adjust the position of the tightening opening 5 of the tightening shaft 4 so that the tightening opening 5 is exposed in the second clamping groove 3 (to prevent the tightening opening 5 from rotating to the back of the second clamping groove 3 and being hidden). Figure 5 As shown;

[0035] At this time, insert the tail end of the printing plate into the tightening opening 5 of the tightening shaft 4, and then manually rotate the tightening nut 7, so that the tightening nut 7 drives the tightening shaft 4 to rotate, and the tightening shaft 4 rotates and drives the tightening opening 5 to rotate and bite, so that the tail end of the printing plate can be twisted into the gap between the second clamping groove 3 and the tightening shaft 4, so that the twisting and clamping work of the tail end of the printing plate is completed by rotating the tightening shaft 4, so that the entire printing plate can be installed on the drum;

[0036] In order to facilitate the lateral positioning of the printing plate in the second plate clamping groove 3 of the drum, butterfly springs 6 are fixedly sleeved on the outer walls of both ends of the tightening shaft 4;

[0037] During actual use, the butterfly springs 6 on both sides will be in a compressed state, so that a reaction force toward the middle can be formed by the compressed butterfly springs 6 on both sides, so that the printing plate in the first clamping groove 3 can be pressed sideways through the formed reaction force, so that the printing plate can be pressed and positioned conveniently, so that the two sides of the printing plate can be kept vertically flush with the two sides of the roller, so that they are in the same vertical plane, thereby improving the positioning effect of the printing plate during installation, effectively avoiding the side protrusion of the printing plate, and improving the subsequent printing production quality.

[0038] To sum up, the utility model is convenient for installing the printing plate clamping roller, and can drive the tightening shaft to rotate by manual rotation, so that the tail end of the printing plate can be twisted into the second clamping groove 3 through the rotation of the tightening shaft, completing the fixed installation of the tail end of the printing plate. In actual use, it has a more convenient printing plate installation effect, a fast installation speed, and simple and convenient installation operation steps. It has the characteristics of time-saving and labor-saving installation, and the structural performance is good, which is suitable for promotion and use.
