Description
Technical Field
The utility model relates to a lithography apparatus field particularly, relates to an automatic compression roller device of compensation.
Background
At present, in the printing and coating industries, in order to transfer ink, glue or paint on a substrate continuously, stably and uniformly, a rubber press roller is used for pressing the substrate on the surface of a metal roller, and the pressing mode of the rubber press roller is various. A motor drives a lead screw which drives the rubber compression roller to move up and down; and a rubber press roller is fixed on a slide block of the linear guide rail, and an air cylinder is connected with the slide block to move up and down.
The rubber compression roller has the hardness, and a plurality of additives are required in the rubber refining process, so that the hardness, the surface smoothness, the plasticity and other properties of the rubber are ensured. Bubbles generated in the banburying process of the rubber are removed, cracks and air holes cannot be formed when the rubber is coated on the outer surface of the steel roller, the rubber is tightly combined with the steel roller, and the delaminating phenomenon cannot be generated.
A motor is used for driving a lead screw to drive a rubber compression roller to be connected with a printing plate roller, and the mode belongs to a hard contact mode and has no flexible buffering performance. The degree of contact between the press roll and the printing plate roll is controlled by the vision and the feeling of an operator, and no data is available for quantifying the degree of contact between the press roll and the printing plate roll. When the pressing is shallow, the printing ink or glue on the metal plate roller cannot be transferred to the substrate in a whole plate, and after the operator finds that the pressing degree of the screw rod is required to be continued; if the pressing depth is large, the base material is stretched, the printing color register position can be deviated, and most seriously, after the rubber roller is seriously pressed, the original elasticity is difficult to recover, permanent damage is caused, even the rubber roller is scrapped, and the loss is caused to a company.
The device also has an imprinting contact mode, wherein the cylinder drives the rubber compression roller to be connected with the printing roller on the linear guide rail and vertically press the printing roller on the metal roller from top to bottom, the imprinting mode also has the problem of lengthening the base material, the equipment needs to be stopped when winding and unwinding, the printing compression roller needs to be lifted, the base material shrinks, and the base material shortens; when the machine is started, the press roller is pushed downwards by the air cylinder until the press roller contacts with the printing plate roller, and the base material is elongated. When the press roller is lifted up, the base material shrinks, when the press roller is pressed down, the material is elongated, and the stretching and shrinking of the material greatly influence the accuracy of printing color register.
No matter the motor drags the compression roller, still the cylinder promotes the compression roller and reciprocates along linear guide, and the substrate all can be elongated or shrink, all influences the effect of printing chromatography, extravagant substrate. The motor drives the screw rod to drive the press roller to be in hard contact with the plate roller, and the rubber press roller is easy to deform and even scrap. The air cylinder is connected with the compression roller to move linearly along the linear guide rail, although the air pressure of the air cylinder can be adjusted, the compression roller and the printing plate roller are not in hard connection in contact, but the material is stretched or shrunk. This is a disadvantage of both stamping methods.
