Description

Technical Field

[0001] This utility model relates to the field of four-color printing press technology, specifically, to a two-page four-color printing press. Background Technology

[0002] A four-color printing press is a device that enables four-color printing technology. Four-color printing, also known as CMYK printing, is a common printing method that obtains various colors by mixing cyan, magenta, yellow, and black inks in different proportions.

[0003] In existing four-color printing presses, the transmission system starts the machine, enabling all components to operate. The ink supply system provides ink to the printing system, ensuring sufficient ink supply during printing. The printing plate contacts the paper, allowing the ink to be evenly applied. The doctor blade scrapes away excess ink, forming a clear printed pattern. However, in actual use, the following problem exists: when the printed paper is wound up, the ink is not yet dry, and due to the winding process, the ink can easily mix, resulting in damage to the printed pattern and causing trouble for the operators. To address this issue, we propose a two-part four-color printing press to solve the above problems. Utility Model Content

[0012] As a preferred embodiment, mounting blocks are fixedly connected to both sides of the connecting rod, and mounting bolts are provided on the surface of the mounting blocks.

[0013] The above technical solution facilitates the assembly and disassembly of the connecting rod through the installation block and installation bolts.

[0014] As a preferred embodiment, both sides of the inner cavity of the box are fixedly connected to bearing seats, and rollers are rotatably connected to the surface of the bearing seats.

[0018] As a preferred embodiment, the bottom of the printing machine body is fixedly connected to four surrounding posts, and the bottom of each post is fixedly connected to an anti-slip pad.

[0019] The above technical solution, with its fixed column, facilitates the support of the equipment.

[0020] As a preferred embodiment, the box has openings on both sides and a door on the surface of the shell.

[0021] The above technical solution allows the printed paper to be transported through the port.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model provides a four-color printing press with the following advantages.

[0024] 1. This utility model utilizes a hot air blower to effectively generate suction using its own negative pressure, which drives the suction pipe to draw in air. The air is then converted into hot air by the hot air blower and discharged through the combination of the air outlet pipe, air outlet head, and air outlet. At the same time, the air enters the inner cavity of the chamber through the through hole to heat and dry the printed paper, facilitating the subsequent winding process. Through the bearing, the rotating rod can rotate in its inner cavity, thereby driving the rotating blades to rotate. This effectively converts the discharged direct airflow into diffused airflow, which is evenly discharged onto the surface of the paper. It also reduces the wind speed of the discharged airflow and improves the drying efficiency.

[0025] 2. This utility model uses an electric push rod to easily move the push plate, which in turn moves the connecting rod. The connecting rod then moves the limiting wheel downward to fit against the edge of the paper, thus limiting the paper and preventing it from shaking due to the exhaust airflow, thereby improving the stability of drying. The roller and shaft seat allow the paper to slide on its surface, and the limiting groove improves the stability of the push plate's sliding. The mounting block and mounting bolts facilitate the assembly and disassembly of the connecting rod. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present utility model.

[0032] Example 1;

[0033] Please see Figure 1-3 This utility model relates to a four-color printing press, comprising a printing press body 1, a housing 2 fixedly connected to the top left side of the printing press body 1, a shell 3 fixedly connected to the top of the housing 2, an mounting plate 12 fixedly connected to the inner cavity of the shell 3, a hot air blower 13 fixedly mounted on the top of the mounting plate 12, an air suction pipe 14 fixedly connected to one side of the hot air blower 13, a filter head 15 fixedly connected to one side of the air suction pipe 14, an air outlet pipe 16 fixedly connected to the side of the hot air blower 13, an air outlet head 17 fixedly connected to the bottom of the air outlet pipe 16, a bearing 10 fixedly connected to the center of the top of the inner cavity of the housing 2, a rotating rod 11 rotatably connected to the inner cavity of the bearing 10, and rotating blades 9 fixedly connected to all four sides of the rotating rod 11.

[0034] Through the above technical solution, the hot air blower 13 can effectively utilize its own negative pressure to generate suction and drive the suction pipe 14 to absorb air. The air is converted into hot air by the hot air blower 13 and discharged through the cooperation of the air outlet pipe 16, the air outlet head 17 and the air outlet 18. At the same time, the air enters the inner cavity of the box 2 through the through hole 8 to heat and dry the printed paper, which is convenient for the subsequent winding work. Through the bearing 10, the rotating rod 11 can rotate in its inner cavity, thereby driving the rotating blade 9 to rotate, which can effectively convert the discharged direct air into diffused air and evenly discharge it to the surface of the paper. At the same time, it can also reduce the wind speed of the discharged air and improve the drying efficiency.

[0035] Example 2;

[0036] like Figure 2 and Figure 4 As shown, both sides of the inner cavity of the housing 2 are fixedly connected to the adjustment shell 4. The top of the inner cavity of the adjustment shell 4 is fixedly connected to the electric push rod 19. The bottom of the electric push rod 19 is fixedly connected to the push plate 20. The surface of the push plate 20 is fixedly connected to the connecting rod 21. The surface of the connecting rod 21 is fixedly connected to the limit wheel 5.

[0037] Through the above technical solution, the electric push rod 19 facilitates the movement of the push plate 20, which in turn causes the push plate 20 to move the connecting rod 21. The connecting rod 21 then causes the limiting wheel 5 to move downward and fit against the edge of the paper, thus limiting the paper and preventing it from shaking due to the influence of the exhaust airflow, thereby improving the stability of drying.

[0038] Example 3;

[0039] like Figure 1-4 As shown, limiting grooves are provided on both sides of the inner cavity of the adjusting shell 4, and both sides of the pushing plate 20 are slidably connected to the inner cavity of the limiting groove. Mounting blocks are fixedly connected to both sides of the connecting rod 21, and mounting bolts are provided on the surface of the mounting blocks. Shaft seats 7 are fixedly connected to both sides of the inner cavity of the housing 2, and rollers 6 are rotatably connected to the surface of the shaft seats 7. Through holes 8 are provided on both sides of the top of the inner cavity of the housing 2. An air outlet 18 is provided at the bottom of the inner cavity of the housing 3, and the bottom of the air outlet 18 fits against the top of the through hole 8. Fixing columns are fixedly connected to all four sides of the bottom of the printing machine body 1, and anti-slip pads are fixedly connected to the bottom of the fixing columns. Openings are provided on both sides of the housing 2, and a door is provided on the surface of the housing 3.

[0040] Through the above technical solution, the paper can slide on its surface through the roller 6 and the bearing 7, the sliding stability of the push plate 20 is improved through the limiting groove, and the connecting rod 21 is easy to disassemble and assemble through the mounting block and mounting bolt.

[0041] The working principle of this utility model is as follows: First, the user places the printed paper into the inner cavity of the box 2 through the openings on both sides of the box 2, where it falls onto the surface of the roller 6. Then, the user holds one end of the paper. Next, the user starts the electric push rod 19 through the external controller. The electric push rod 19 facilitates the movement of the push plate 20, which in turn causes the push plate 20 to move the connecting rod 21. The connecting rod 21 then causes the limiting wheel 5 to move downwards and fit against the edge of the paper, thus limiting the paper's position. Then, the user starts the hot air blower 13 through the external controller. 3. It can effectively utilize its own negative pressure to generate suction and drive the suction pipe 14 to absorb air. The air is then converted into hot air by the hot air blower 13 and discharged through the air outlet 16, the air outlet head 17 and the air outlet 18. At the same time, the air enters the inner cavity of the box 2 through the through hole 8 to heat and dry the printed paper. Due to the influence of the airflow, the rotating blade 9 drives the rotating rod 11 to rotate in the inner cavity of the bearing 10, which can effectively convert the discharged direct current hot air into diffused air and evenly discharge it to the surface of the paper. At the same time, it can also reduce the wind speed of the discharge airflow and improve the drying efficiency.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
