Description

Technical Field

[0001] This invention belongs to the field of printing press technology, and more specifically, relates to a printing press operation displacement deviation compensation and correction device. Background Technology

[0002] A printing press is a machine for printing text and images. Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas with text and images on the printing plate by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates, thereby reproducing a printed product identical to the printing plate. During the printing process, the paperboard may become biased to one side, resulting in misalignment of the printed product.

[0003] Currently, when the cardboard to be printed shows a displacement deviation, the machine needs to be stopped and manually adjusted. It cannot automatically compensate for and correct the misaligned cardboard. In addition, dust or tiny impurities may remain on the surface of the cardboard before printing. Current printing machines cannot automatically clean the surface while the cardboard is moving, which reduces the printing accuracy. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, when the dual-axis motor is working, the two mounting brackets drive the two compensation and correction frames to move inward simultaneously, which achieves an automatic compensation and correction effect on the printing paperboard. The setting of the two sets of compensation and correction shafts allows the two sets of compensation and correction shafts to rotate when the printing paperboard comes into contact with them, thus avoiding damage or wear on the front and back sides of the printing paperboard while achieving the compensation and correction effect.

[0018] In addition, when the two mounting brackets move inward, the two linkage inclined blocks push the four movable mounting blocks outward, causing the four positioning rollers to separate from the printing paperboard, releasing the positioning of the printing paperboard by the four positioning rollers. After the compensation and correction are completed, the four movable mounting blocks are reset under the action of the eight support springs A, so that the four positioning rollers continue to contact the printing paperboard, ensuring that the printing paperboard is in a relatively stable state after the compensation and correction.

[0019] 2. In this invention, because two cleaning sponges are installed on two rectangular cleaning frames and the inner sides of the two cleaning sponges are in contact with the printing paperboard, the surface of the printing paperboard to be printed is automatically cleaned, thus improving the printing quality. Furthermore, because the dust collection box is slidably installed on the outside of the two circular mounting rods C, it collects the dust after cleaning, making it convenient for staff to centrally process the cleaned dust.

[0020] 3. In this invention, when the printed paperboard moves, two rubber friction wheels drive two circular auxiliary shafts to rotate, and the two circular auxiliary shafts can drive four spiral blades to rotate simultaneously, which can help to remove the dust after cleaning.

[0021] In addition, when the two linkage inclined blocks push the four movable mounting blocks outward, the dust collection box can move under the action of the two linkage inclined rods and the two circular push rods, causing the dust in the dust collection box to shake, thus preventing the collected dust from accumulating in the same position and improving the utilization effect of the dust collection box.

[0050] Example 3: Figures 8 to 11As shown, an auxiliary unit 6 is added based on Embodiments 1 and 2. The auxiliary unit 6 includes: rectangular mounting plates 601, circular auxiliary shafts 602, and rubber friction wheels 603. Four rectangular mounting plates 601 are provided, and the four rectangular mounting plates 601 are welded to the right side of four movable mounting blocks 104. Two circular auxiliary shafts 602 are provided, and the two circular auxiliary shafts 602 are rotatably mounted on the four rectangular mounting plates 601.

Furthermore, since the two linkage diagonal rods 606 are welded to the two rectangular mounting plates 601 below, and the two linkage diagonal rods 606 are tangent to the two circular push rods 505, and the four support springs B504 are located on the left and right sides of the dust collection box 502, when the two linkage diagonal blocks 305 push the four movable mounting blocks 104 outward, the dust collection box 502 can move under the action of the two linkage diagonal rods 606 and the two circular push rods 505, causing the dust in the dust collection box 502 to shake, avoiding the dust from accumulating in the same position after collection, and improving the utilization effect of the dust collection box 502.

[0051] The specific usage and function of this embodiment are as follows:

[0052] In use, the operator first connects the printing press connecting frame 101 to the printing press using bolts. Then, the printing paperboard 2 to be printed is passed through two rubber friction wheels 603, two cleaning sponges 403, four positioning rollers 107, and two compensation and correction frames 303. Because the two cleaning sponges 403 are mounted on two rectangular cleaning frames 402, and the inner sides of the two cleaning sponges 403 are in contact with the printing paperboard 2, the surface of the printing paperboard 2 to be printed is automatically cleaned, improving printing quality. Furthermore, because the dust collection box 502 is slidably mounted on two circular mounting rods C... The exterior of 501 collects the cleaned dust, facilitating centralized disposal by staff. When the printing cardboard 2 moves, two rubber friction wheels 603 drive two circular auxiliary shafts 602 to rotate. These shafts, in turn, drive four spiral blades 604 to rotate simultaneously, aiding in the removal of cleaned dust. When two linkage inclined blocks 305 push four movable mounting blocks 104 outwards, the dust collection box 502 moves under the action of two linkage inclined rods 606 and two circular push rods 505, allowing the dust collection box 502 to move. The dust is shaken, preventing the collected dust from accumulating in one place and improving the utilization efficiency of the dust collection box 502. When the sensor detects displacement of the printing paperboard 2, the controller controls the dual-axis motor 306 to work. When the dual-axis motor 306 works, the two mounting brackets 302 drive the two compensation and correction frames 303 to move inward simultaneously, achieving an automatic compensation and correction effect on the printing paperboard 2. The setting of the two sets of compensation and correction shafts 304 ensures that when the printing paperboard 2 comes into contact with the two sets of compensation and correction shafts 304, the two sets of compensation and correction shafts 304 can rotate, thus achieving the compensation and correction effect. Under the premise of achieving the desired effect, damage or wear on the front and back sides of the printing paperboard 2 is avoided. When the two mounting brackets 302 move inward, the two linkage inclined blocks 305 push the four movable mounting blocks 104 outward, causing the four positioning rollers 107 to separate from the printing paperboard 2, releasing the positioning of the printing paperboard 2 by the four positioning rollers 107. After the compensation and correction are completed, the four movable mounting blocks 104 are reset under the action of the eight support springs A105, so that the four positioning rollers 107 continue to contact the printing paperboard 2, ensuring that the printing paperboard 2 is in a relatively stable state after the compensation and correction.
