Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, and more specifically, to a printing roller with adjustable printing size. Background Art

[0002] The printing roller is the core component of the printing machinery. Its surface finish and geometric accuracy will have a significant impact on the quality of the printed product, especially when printing exquisite printed products. The slightest error will reduce the overall effect of the printed product, making both sides of the double-printed product appear blurry or distorted. When printing the product again, due to the different sizes of the products, in order to improve the efficiency of printing the products, it is necessary to replace the rollers of different models according to the size of the products, which will not only easily lead to increased costs, but also require repeated disassembly and installation of the rollers.

[0003] After searching, the Chinese patent with publication number CN206264555U discloses a color printing roller with adjustable size. The advantage of this structure is that the movable cylinder can move left and right through the setting of the card slot, and the mutual movement of the movable cylinder and the supporting cylinder is more portable through the mutual connection of the sliding groove and the sliding bar. The connection between the fastening sleeve and the gasket makes the connection between the screw and the movable cylinder more stable, and the structural strength is improved.

[0004] However, in actual use, since this structure adjusts the size of the printing roller by driving the support cylinder to move along the inside of the movable cylinder through a screw, and usually the printing roller needs to be used with a corresponding brush sleeve, after increasing the distance between the movable cylinder and the support cylinder, in order to meet the size of the printing roller, the corresponding brush sleeve needs to be replaced, which will increase the cost, and when the elastic part is stained with paint, it needs to be cleaned in time, otherwise it will easily affect the ductility of the elastic part and easily cause damage to the elastic part.
