[0002] Four-color offset printing presses generally refer to offset printing presses that use yellow, magenta, cyan, and black inks to reproduce the various colors of a color original. They are one of the many printing equipment available today and hold an indispensable position in the field of automated printing.

[0003] Existing four-color offset printing machines lack noise blocking and absorption structures, and cannot effectively block and absorb noise from specific directions, so their overall practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a low-noise, sound-insulating four-color offset printing machine that can be easily installed on the outside of the offset printing machine. It can effectively block and absorb noise from a specific direction, reduce the impact of equipment operation on surrounding workers, and is highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A low-noise, sound-insulating four-color offset printing machine includes a base on which four adhesive coating mechanisms are mounted. Two first sound-insulating plates and two second sound-insulating plates are respectively mounted on the side surfaces of the adhesive coating mechanisms. The first and second sound-insulating plates have the same structure. The first sound-insulating plate includes a first perforated plate, sound-absorbing cotton, and a second perforated plate. A support screw is fixedly connected to each of the four corner positions on one side of the first perforated plate. The external threads of the support screw are threaded onto a movable connecting seat. The end face of the movable connecting seat is provided with a snap-fit ​​hole, and a circular permanent magnet is snapped into the inside of the snap-fit ​​hole.

[0007] By adopting the above technical solution, a first sound insulation board and a second sound insulation board can be easily installed to block and absorb noise propagating in a specific direction, thereby reducing the impact of the offset printing machine on surrounding workers.

[0008] Furthermore, a connecting rod is fixedly connected to each of the four corner positions on one side of the outer surface of the first perforated plate. The corner position of the second perforated plate is provided with a mounting hole, and the mounting hole corresponds to the position of the connecting rod. One end of the connecting rod passes through the interior of the mounting hole. The sound-absorbing cotton is located between the first perforated plate and the second perforated plate. One end of the connecting rod is threadedly connected to a limit knob.

[0009] By adopting the above technical solution, the first sound insulation panel and the second sound insulation panel can be easily assembled.

[0010] Furthermore, a transparent plastic baffle is installed between two adjacent second sound insulation panels.

[0011] By adopting the above technical solutions, the sound insulation effect can be further improved.

[0012] Furthermore, two rotating mounting holes are provided on the outer surface of the transparent plastic baffle, and a handle is rotatably mounted inside the rotating mounting holes, with a buckle block fixedly connected to one end of the handle.

[0013] By adopting the above technical solution, the transparent plastic baffle can be installed conveniently, and the position of the transparent plastic baffle can be ensured to be stable.

[0014] Furthermore, the first and second sound insulation panels, which are wrapped around the outside of the same adhesive coating mechanism, are alternately distributed.

[0015] By adopting the above technical solutions, the sound insulation effect is effectively guaranteed.

[0016] Furthermore, a paging machine is installed at one end of the base, and a conveying mechanism is provided between two adjacent glue-applying mechanisms.

[0017] By adopting the above technical solutions, the stable operation of the offset printing machine can be effectively ensured.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model can use a first sound insulation plate and a second sound insulation plate wrapped around the outside of the glue coating mechanism to block sound propagating in a specific direction. Since the first sound insulation plate and the second sound insulation plate are both installed on the surface of the glue coating mechanism through a support screw and a movable connecting seat, there is space between the first sound insulation plate and the glue coating mechanism, which can effectively facilitate the heat dissipation of the glue coating mechanism. Since the first sound insulation plate and the second sound insulation plate are both composed of a first perforated plate and a second perforated plate, and sound-absorbing cotton is placed between the first perforated plate and the second perforated plate, noise can be effectively eliminated, thereby reducing the impact of noise from the offset printing machine on surrounding workers. At the same time, a ring-shaped permanent magnet is snapped on one end of the movable connecting seat, so the first sound insulation plate and the second sound insulation plate can be easily adsorbed and fixed on the outer surface of the glue coating mechanism using the permanent magnet. The installation and operation of the entire sound insulation mechanism is quick and convenient.

[0020] 2. This utility model can use a transparent plastic baffle to further improve the sound insulation effect. At the same time, the staff can easily observe the working status of the glue application mechanism from the transparent plastic baffle. The staff can also easily twist the buckle block with the handle to lock the transparent plastic baffle block into place on the inside of the second sound insulation board to ensure the stability of the transparent plastic baffle.

[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 3A low-noise, sound-insulating four-color offset printing machine includes a base 1. Four adhesive application mechanisms 3 are mounted on the base 1. Two first sound-insulating plates 4 and two second sound-insulating plates 5 are respectively installed on the side surfaces of the adhesive application mechanisms 3. The first and second sound-insulating plates 4 and 5 have identical structures. The first sound-insulating plate 4 includes a first perforated plate 8, sound-absorbing cotton 9, and a second perforated plate 10. A support screw 13 is fixedly connected to each of the four corner positions on one side of the first perforated plate 8. A movable connecting seat 14 is threaded onto the external surface of the support screw 13. The base 1 has snap-fit ​​holes, and a circular permanent magnet is installed inside the snap-fit ​​holes. A page separator 2 is installed at one end of the base 1. A conveying mechanism 12 is set between two adjacent glue-applying mechanisms 3. The first sound insulation plate 4 and the second sound insulation plate 5 are alternately distributed around the outside of the same glue-applying mechanism 3. A connecting rod 15 is fixedly connected to each of the four corners of the outer surface of one side of the first perforated plate 8. The corners of the second perforated plate 10 are provided with mounting holes, and the mounting holes correspond to the positions of the connecting rods 15. One end of the connecting rod 15 passes through the inner part of the mounting hole. The sound-absorbing cotton 9 is located between the first perforated plate 8 and the second perforated plate 10. One end of the connecting rod 15 is threadedly connected to a limit knob 16. The first sound-insulating plate 4 and the second sound-insulating plate 5, which are wrapped around the glue-applying mechanism 3, can be used to block sound propagating in a specific direction. Since the first sound-insulating plate 4 and the second sound-insulating plate 5 are both mounted on the surface of the glue-applying mechanism 3 through the support screw 13 and the movable connecting seat 14, there is space between the first sound-insulating plate 4 and the second sound-insulating plate 5 and the glue-applying mechanism 3, which can effectively facilitate the heat dissipation of the glue-applying mechanism 3. The operation is convenient because both the first sound insulation plate 4 and the second sound insulation plate 5 are composed of the first perforated plate 8 and the second perforated plate 10. The sound-absorbing cotton 9 is set between the first perforated plate 8 and the second perforated plate 10, which can effectively eliminate noise and reduce the impact of the noise of the offset printing machine on the surrounding staff. At the same time, a ring-shaped permanent magnet is snapped on one end of the movable connecting seat 14, so the first sound insulation plate 4 and the second sound insulation plate 5 can be easily attracted and fixed to the outer surface of the glue coating mechanism 3 by using the permanent magnet. The installation and operation of the entire sound insulation mechanism is quick and convenient.

[0028] Reference Figure 2 , Figure 4 A transparent plastic baffle 6 is installed between two adjacent second sound insulation panels 5. Two rotating mounting holes are provided on the outer surface of the transparent plastic baffle 6, and a handle 7 is rotatably installed inside the rotating mounting holes. One end of the handle 7 is fixedly connected to a buckle block 11. The transparent plastic baffle 6 can be used to further improve the sound insulation effect. At the same time, the staff can easily observe the working status of the glue application mechanism 3 from the transparent plastic baffle 6, and can easily twist the buckle block 11 with the handle 7. The buckle block 11 is used to lock into the inner side of the second sound insulation panel 5 to ensure the stability of the transparent plastic baffle 6.

[0029] Working Principle: When in use, the offset printing machine is installed in the designated location. The collating machine 2 then transports the stacked base paper one by one into the conveying mechanism 12. The conveying mechanism 12 allows the printing base paper to pass through the interior of the coating mechanism 3 one by one. Different coating mechanisms 3 can apply different pigments to the printing base paper, automating the entire printing operation. During operation, the first soundproof plate 4 and the second soundproof plate 5, which are wrapped around the coating mechanism 3, can block sound propagating in specific directions. Since both the first soundproof plate 4 and the second soundproof plate 5 are mounted on the surface of the coating mechanism 3 via the support screw 13 and the movable connecting seat 14, there is space between the first soundproof plate 4 and the second soundproof plate 5 and the coating mechanism 3, effectively facilitating the coating process. The heat dissipation operation of the structure 3 is also improved. Since the first sound insulation plate 4 and the second sound insulation plate 5 are both composed of the first perforated plate 8 and the second perforated plate 10, and the sound-absorbing cotton 9 is placed between the first perforated plate 8 and the second perforated plate 10, the noise can be effectively eliminated, thereby reducing the impact of the noise of the offset printing machine on the surrounding staff. At the same time, a ring-shaped permanent magnet is snapped on one end of the movable connecting seat 14, so the first sound insulation plate 4 and the second sound insulation plate 5 can be easily attracted and fixed to the outer surface of the glue coating mechanism 3 by the permanent magnet. The installation and operation of the entire sound insulation mechanism is quick and convenient. The sound insulation effect can be further improved by using the transparent plastic baffle 6. At the same time, the staff can easily observe the working status inside the glue coating mechanism 3 through the transparent plastic baffle 6.
