Description

Technical Field

[0001] The utility model relates to the technical field of printing paper, in particular to a printing paper flattening device. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate and installed on the printing press. Then, the ink is applied to the places with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed products as the printing plate. Before entering the printing, the existing paper may not fit well due to the elasticity and flatness of the paper, or due to environmental factors, such as the ends of the paper being tilted up or the middle being bulged, which causes the printing press to print unclearly on the paper.

[0003] According to the Chinese patent with announcement number: CN220722925U, a paper printing smoothing device of a printing press includes a support box, a bracket is fixedly installed on the upper surface of the support box, a first cylinder is fixedly installed at the middle position of the upper surface of the bracket, the output end of the first cylinder passes through the top side of the inside of the bracket, and the output end of the first cylinder is fixedly connected to a fixed plate, a slide groove is provided on the fixed plate, two sliders are slidably installed in the slide groove, a driving mechanism is provided on the fixed plate, the driving mechanism is transmission-connected to the slider, and the lower surface of the slider is fixedly connected to a first connecting plate.

[0004] In the above scheme, two pressure rollers are driven by a motor to level the paper, which results in the following disadvantages: when the leveling device is in use, the paper can only be leveled once, so that the paper may still have some wrinkles, resulting in reduced flatness and quality of the paper. Utility Model Content

[0005] The utility model aims to provide a printing paper leveling device to solve the problem that the leveling device can only level the paper once when in use, so that the paper may still have some wrinkles, resulting in reduced flatness and quality of the paper.

[0007] Preferably, the front and rear sides of the inner wall of the installation frame are respectively provided with slide grooves, the front and rear sides of the outer walls of the two moving blocks are respectively fixed with sliders, and the two sliders are respectively slidably arranged in the two slide grooves.

[0008] Preferably, a second hydraulic push rod is fixed to the inner top surface of the first L-shaped plate, a connecting plate is fixed to one end of the telescopic rod of the second hydraulic push rod, and the bottom surface of the connecting plate is fixedly connected to the top surface of the mounting frame.

[0009] Preferably, the bottom surface of the pressing plate is provided with an anti-sticking layer.

[0010] Preferably, two guide plates are fixed to the top surface of the U-shaped seat.

[0011] Preferably, a collection box is fixed to the rear side of the outer wall of the U-shaped seat.

[0012] Compared with the prior art, a printing paper leveling device adopting the above technical solution has the following features:

[0013] Beneficial effects:

[0014] 1. During use, the pressing roller helps to level the paper, and the pressing plate helps to level the paper for the second time, thereby preventing the paper from being partially wrinkled, thereby improving the flatness and quality of the paper;

[0015] Second, during use, the sliding groove and the slider are used to limit the moving block, which is beneficial to prevent the moving block from shifting, thereby improving the stability of the moving block during movement.

The guide plate helps guide the paper to ensure that the position of the paper on the conveyor belt is centered and stable, which helps prevent the paper from shifting or skewing during transportation, and helps improve the accuracy of the position of the paper during transportation. The collection box helps the staff to place and store the flattened paper, which is convenient for the staff to collect uniformly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] During use, the staff first places the paper on the conveyor belt 4 for transportation. When the paper moves to the bottom of the two pressure rollers 12, the conveyor belt 4 is stopped, and the drive motor 7 is started to rotate the bidirectional screw 8, thereby driving the two moving blocks 9 to move away from each other, so that the two pressure rollers 12 roll on the paper, so that the wrinkles of the paper can be flattened. Then the conveyor belt 4 is started again to allow the paper to continue to be transported. When the paper moves to the bottom of the pressure plate 14, the conveyor belt 4 is stopped, and the first hydraulic push rod 13 is started to move the pressure plate 14 downward to flatten the paper. The pressure roller 12 is used to facilitate the flattening of the paper, and the pressure plate 14 is used to facilitate the secondary flattening of the paper, thereby preventing the paper from partially wrinkling, thereby improving the flatness and quality of the paper.

[0025] like Figure 1-Figure 4 As shown, the front and rear sides of the inner wall of the installation frame 5 are respectively provided with slide grooves 15 , and the front and rear sides of the outer walls of the two moving blocks 9 are respectively fixed with sliders 16 , and the two sliders 16 are respectively slidably arranged in the two slide grooves 15 .

[0027] like Figure 1-Figure 4 As shown, a second hydraulic push rod 17 is fixed to the inner top surface of the first L-shaped plate 2, a connecting plate 18 is fixed to one end of the telescopic rod of the second hydraulic push rod 17, the bottom surface of the connecting plate 18 is fixedly connected to the top surface of the mounting frame 5, and an anti-sticking layer 19 is provided on the bottom surface of the pressure plate 14.

[0028] In use, by starting the second hydraulic push rod 17, the connecting plate 18 can be raised and lowered, and the mounting frame 5 and the pressing roller 12 can be raised and lowered, so that printing papers of different thicknesses can be leveled and the practicality of the device can be improved. The anti-sticking layer 19 can prevent the paper from adhering to the bottom surface of the pressing plate 14, so that when the pressing plate 14 is reset, the paper will not be lifted up, which helps to ensure that the paper can be smoothly transported.

[0029] like Figure 1 and Figure 2 As shown, two guide plates 20 are fixed to the top surface of the U-shaped seat 1 , and a collection box 21 is fixed to the rear side of the outer wall of the U-shaped seat 1 .

[0030] In use, the guide plate 20 is used to guide the paper, ensuring that the position of the paper on the conveyor belt 4 is centered and stable, preventing the paper from deflecting or tilting during transportation, and improving the accuracy of the position of the paper during transportation. The collection box 21 is used to facilitate the staff to place and store the flattened paper, so that the staff can collect it uniformly.
