Problems solved by technology
[0003] However, in order to ensure that the existing printing roller has sufficient weight, the wall thickness of the cylindrical printing roller is usually set relatively large.
Although the printing stability is solved in this way, the material consumption is large, which increases the production cost of the printing roller

Embodiment Construction
[0029] Such as figure 1 and figure 2 As shown, the printing roller includes a cylinder body 1 in the shape of a cylinder. The counterweight assembly of the printing roller includes an annular concave connection groove 1a on the inner side of the cylinder body 1, and also includes two arc-shaped counterweight bars: bar body one 2 and bar body two 3, and the inner side of the bar body one 2 The end is hinged with the inner end of the bar body two 3, and the outer sides of the above bar body one 2 and the bar body two 3 are embedded in the connecting groove 1a, and there is a gap between the connecting groove 1a and the bar body one 2 that can clamp the two snap-in structure.
[0030] The clamping structure includes a positioning hole 2a in which the side of the strip body 12 is recessed, and the positioning hole 2a has a spring 4 and a ball 5 inside, and the above-mentioned ball 5 partially protrudes from the positioning hole under the elastic force of the spring 4 2a, and t...

The invention provides a balance weight assembly of a printing roll, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The printing roll comprises a cylindrical barrel, the balance weight assembly comprises a connecting groove which is annularly recessed in the inner side of the barrel, and further comprises two arc-shaped balance weight strips, a first strip and a second strip, the inner end of the first strip is hinged to the inner end of the second strip, the outer side of the first strip and the outer side of the second strip are embedded in a connecting groove, a clamping structure is arranged between the connecting groove and the first strip, and by the clamping structure, the connecting groove can be in clamped connection withthe first strip. The balance weight assembly of the printing roll is high in stability.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a counterweight assembly of a printing roller. Background technique [0002] The printing roller is an important accessory of the offset printing machine. In order to ensure the printing quality, usually the printing roller has a certain weight. [0003] However, in order to ensure that the existing printing roller has sufficient weight, the wall thickness of the cylindrical printing roller is generally set relatively large. Although the printing stability is solved in this way, the material consumption is large, which increases the manufacturing cost of the printing roller. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a printing roller counterweight assembly which can improve the stability of the printing roller and has a compact structure. [0005] The purpose of the present inv...
