Description

Technical Field

[0001] This utility model belongs to the field of paper pressing technology for printing presses, specifically a paper pressing device for printing presses. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of a plate-mounting, inking, printing, and paper feeding / folding mechanism. 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. Ink is then applied manually or by the printing press to the areas of the printing plate containing the text and images. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate. The invention and development of the printing press has played a vital role in the dissemination of human civilization and culture.

[0003] A patent with publication number CN107297778B discloses a high-efficiency paper pressing device for a paper printing machine, including a frame; a pressure plate for placing paper is provided inside the frame, and sliders are fixed on both sides of the pressure plate. A groove matching the slider is formed on the inner wall of the frame cavity, and the slider slides and engages in the groove; the pressure plate is provided with a height adjustment mechanism; gears are symmetrically arranged on the upper part of the frame, with cranks connected to the bottom of the gears and pressure roller supports connected to the other end of the cranks, on which pressure rollers are mounted; a double-sided rack is provided at the center of the upper inner cavity of the frame, meshing with the gears on both sides; a drive mechanism for moving the double-sided rack is provided at the top of the frame. This invention can effectively eliminate wrinkles on the paper while pressing it, and it is simple to operate and has a good paper pressing effect.

[0004] In current technology, existing paper pressing devices generally use two hydraulic cylinders on the left and right to drive the pressure plate to press the paper. However, when the paper has wrinkles, the pressed paper still has wrinkles. The wrinkles can cause short-touch and discontinuous printing when the printing press is printing.

[0005] Therefore, a paper pressing device for printing presses is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 - Figure 5 This utility model provides a paper pressing device for a printing press, including a paper storage box 12. A placement groove 121 is provided on the bottom inner wall of the paper storage box 12. A motor 125 is fixedly installed on both sides of the paper storage box 12 and at the bottom edge of the placement groove 121. A push roller 126 is fixedly connected to the output end of the motor 125 and is movably sleeved on the inner wall of the paper storage box 12. A cover plate 127 is provided on the outer surface of the paper storage box 12. A lower pressing plate a2 is provided on the top outer surface of the cover plate 127. A lower pressing plate a7 is provided on the bottom surface of the lower pressing plate a2 and is movably sleeved on the bottom inner wall of the cover plate 127. A heating plate a8 is fixedly installed on the bottom surface of the lower pressing plate a7. A connecting heating strip a10 is provided on the top inner wall of the heating plate a8.

[0029] During operation, paper is placed inside the paper storage box 12, and the inclined surface of the placement groove 121 allows the paper to gradually slide down. At this time, the motor 125 rotates the push roller 126, causing the paper to gradually slide from the surface of the placement groove 121 to one side into the interior of the cover plate 127. Then, the lower pressure plate a2 is pressed, and the lower pressure plate a7 on the bottom surface of the lower pressure plate a2 is pressed and adhered to the surface of the paper. As the lower pressure plate a7 continues to press down, the heating plate a8 is heated at high temperature by the connecting heating strip a10. The heat source is used to heat and soften the wood fibers inside the paper, achieving the effect of using the arc groove a9 on the surface of the heating plate a8 to roll and slide on the surface of the paper. At the same time, the wrinkled paper can be smoothed out.

[0030] Furthermore, such as Figures 1 to 3 As shown, the inner walls on both sides of the paper storage box 12 have limiting grooves 122, and the outer surface of the limiting track 123 is fixedly connected with a pressure cardboard 124.

[0031] During operation, the paper is placed inside the paper storage box 12 and processed using the placement sloping groove 121. Then, the limiting rails 123 on both sides of the pressing board 124, under the limitation of the limiting groove 122, press and overlap the paper surface, thereby pressing the paper. The weight of the pressing board 124 and the limiting rails 123 is used to slightly press the paper together, preventing the paper from being too loose and causing multiple sheets of paper to move together during paper feeding.

[0032] Furthermore, such as Figures 1 to 3 As shown, an elastic wire a3 is fixedly connected to the top surface of the lower pressure plate a7, and the other end of the elastic wire a3 is fixedly connected to the top inner wall of the cover plate 127. A limiting track 123 is slidably sleeved on the inner wall of the limiting groove 122.

[0033] During operation, after the pressure plate 124 lightly presses the paper, the motor 125 rotates the push roller 126. The silicone on the surface of the push roller 126 slides on the surface of the paper, and the anti-slip force of the silicone pulls the paper out from the bottom surface of the pressure plate 124. With the continuous rotation of the push roller 126, the paper is moved into the cover plate 127.

[0034] Furthermore, such as Figures 1 to 6As shown, an arc-shaped groove a9 is formed on the bottom surface of the heating plate a8 and at the two side edges. A slot is formed on the outer surface of the lower pressure plate a7. An electric motor a5 is fixedly installed on both sides of the lower pressure plate a7. A push roller a6 is fixedly connected to the output end of the electric motor a5. The push roller a6 is positioned on the inner wall of the slot. An anti-slip silicone strip a4 is fixedly connected to the outer surface of the push roller a6. A limit post a1 is fixedly connected to the top outer surface of the lower pressure plate a7. The outer surface of the limit post a1 is movably sleeved on the outer surface of the cover plate 127. A printing table 11 is fixedly installed on the bottom surface of the paper storage box 12. A printing controller 111 is set on the top surface of the printing table 11. A closed printing cover 112 is oscillatingly connected to the top surface of the printing table 11 and at the bottom edge of the printing controller 111.

[0035] During operation, the lower pressure plate a2 presses down on the lower pressure plate a7, heating and smoothing the paper. Simultaneously, the electric motor a5 rotates the push roller a6, causing the paper to move along the bottom edge of the lower pressure plate a7. This allows the paper to slide effectively and evenly on the bottom surfaces of the lower pressure plate a7 and the heating plate a8. Driven by the push roller a6, the paper enters the enclosed printing chamber 112, where it is then printed.

[0036] Working principle: The paper is placed inside the paper storage box 12 and processed by the placement sloping groove 121. Then, the limiting rails 123 on both sides of the pressing plate 124 are squeezed and overlapped on the surface of the paper under the limitation of the limiting groove 122, thereby pressing the paper. The weight of the pressing plate 124 and the limiting rails 123 is used to slightly press the paper together, so as to avoid the paper being too loose and multiple papers moving together when the paper is conveyed.

[0037] After the pressure plate 124 lightly presses the paper, the motor 125 rotates the push roller 126, and the silicone on the surface of the push roller 126 slides on the surface of the paper. The anti-slip force of the silicone pulls the paper out from the bottom surface of the pressure plate 124, and the paper is moved into the cover plate 127 under the continuous rotation of the push roller 126.

[0038] At this time, the motor 125 rotates the push roller 126, causing the paper to gradually slide from the surface of the inclined groove 121 to one side into the interior of the cover plate 127. At this time, the lower pressure plate a2 is pressed and the lower pressure plate a7 on the bottom surface of the lower pressure plate a2 is pressed and adhered to the surface of the paper. As the lower pressure plate a7 continues to press down, the heating plate a8 is heated at high temperature by the connecting heating strip a10. The heat source is used to heat and soften the wood fibers inside the paper, so that the arc groove a9 on the surface of the heating plate a8 can be used to roll and slide on the surface of the paper. At the same time, the wrinkled paper can be smoothed out.

[0039] At this time, the lower pressure plate a2 presses down on the lower pressure plate a7, and the lower pressure plate a7 heats and smooths the paper. At the same time, the electric motor a5 rotates the push roller a6, and when the push roller a6 rotates, it can drive the paper to move at the bottom edge of the lower pressure plate a7. The paper can slide effectively and evenly on the bottom surface of the lower pressure plate a7 and the heating plate a8. Under the push of the push roller a6, the paper enters the interior of the closed printing chamber 112, and the closed printing chamber 112 performs printing on the paper inside.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
