Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing machines, in particular to an automatic deviation correcting device. Background Art
[0002] A printing press is a machine for printing text and images. Its principle is to first make the text or image to be printed into a printing plate, install it on the printing press, and then apply ink to the place where the text and image are on the printing plate manually or by the printing press, and then directly or indirectly transfer it to paper or other substrates (such as textiles, metal plates). During the printing process, the paper in the paper roll is unrolled and enters the digital printing press. During the unrolling process, the paper is prone to positional deviation, resulting in deviation in the position of the text or image to be printed on the paper, affecting the printing quality, so a correction device is needed.
[0003] The traditional web-correcting device only has the function of correcting the web, which allows the paper to enter the printing press straight. However, the paper may be wrinkled when entering the printing press, which will also affect the printing quality. Utility Model Content
[0004] The utility model aims to provide an automatic deviation-correcting device, which can not only correct the deviation of paper but also level the paper, thereby improving the printing effect and solving the problems mentioned in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic deviation correction device comprises a base, a rectangular groove is horizontally opened in the middle of the upper surface of the base, a screw shaft is rotatably installed in the rectangular groove, and two moving blocks are limitedly installed, the two moving blocks are symmetrically spirally connected to the two ends of the screw shaft, and limiting sleeves are installed on the upper ends of the two moving blocks, a U-shaped frame is horizontally installed in the middle of the upper surface of the base, a steering roller is rotatably installed at the lower end between the U-shaped edges of the two U-shaped frames, the steering roller is stuck in the two limiting sleeves, a lifting electric rod is installed in the middle of the top of the U-shaped frame beam, and light rods are slidably installed at both ends, a mounting plate is jointly installed at the protruding end of the lifting electric rod and the lower ends of the two light rods, two fixed seats are symmetrically installed at both ends of the bottom of the mounting plate, and a clamping roller is rotatably installed between the two fixed seats.
[0006] Preferably, four fixing blocks are installed in pairs at both ends of the front and rear sides of the base, and through holes are provided in the middle of the four fixing blocks. By providing four fixing blocks, the whole device can be easily fixed on the paper inlet of the printing press.
[0007] Preferably, the screws at both ends of the screw shaft are designed to be positive and negative. By setting the threads at both ends of the screw shaft to be opposite, the two moving blocks can move inward or outward at the same time.
[0008] Preferably, the right end of the screw shaft passes through the base and is provided with a knob. By providing the knob, it is convenient to rotate the screw shaft.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] When the utility model is used, the knob is turned, and the rotation of the knob drives the screw shaft to rotate, and the rotation of the screw shaft drives the two moving blocks to move toward the middle, so that the two limit sleeves contact the two sides of the paper and stop, and then the lifting electric rod is started, and the lifting electric rod works to drive the mounting plate to descend, and the mounting plate descends and drives the pressing roller to descend and contact the steering roller, so that not only the deviation of the paper can be corrected, but also the paper can be leveled, thereby improving the printing effect.
