Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing roller cooling device for a printing device which is easy to maintain. Background Art

[0002] A printing press is a mechanical device used to reproduce text or images. It is usually composed of mechanisms such as plate mounting, inking, pressing, and paper feeding. The basic principle of a printing press is to reproduce text or images by engraving text or images on metal blocks, then arranging these metal blocks into pages, applying ink, and then pressing them onto paper.

[0003] In the patent with publication number CN219856381U, it is proposed that the existing cooling methods are mostly wind cooling and water cooling. When cooling the printing, the cooling efficiency of the air cooling method is low. The existing water cooling directly returns the circulating liquid directly to the inside of the liquid storage tank. The temperature of the returned coolant is high and will mix with the uncirculated coolant, which will increase the overall temperature of the coolant, thereby affecting the cooling effect of the coolant. The patent includes a cooling box, the upper surface of the cooling box is fixedly connected to the box cover by bolts, the upper surface of the box cover is installed with a servo motor, the output end of the servo motor is fixedly connected to a stirring column, the outer surface of the stirring column is fixedly connected to a stirring rod, the lower surface of the cooling box is fixedly connected to the liquid storage tank, the liquid storage tank A liquid extraction pump is installed inside the printing device, and the output end of the liquid extraction pump is fixedly connected to a liquid infusion tube. The printing equipment uses a printing cooling device. When in use, the liquid extraction pump can extract the coolant inside the liquid storage tank and flow it into the printing roller through the liquid infusion tube to cool the printing roller. The coolant will flow back to the cooling box for storage and will not mix with the coolant inside the liquid storage tank. This will prevent the temperature of the coolant inside the liquid storage tank from rising, thereby ensuring its cooling effect. However, the following problems still exist in this patent: although the heat dissipation and cooling effect of the coolant can be improved during use, in actual use, in order to ensure printing quality, the printing roller usually needs to be disassembled, and the existing device does not have a quick-disassembly and quick-assembly structure for the printing roller, which is inconvenient for maintenance of the printing roller.

[0004] In view of the above problems, it is necessary to design a printing roller cooling device for a printing device that is easy to maintain, so as to overcome the above problems. Utility Model Content

[0012] As a preferred solution of the present invention, the side wall of the liquid storage box is provided with mounting holes corresponding to the infusion tube, the side wall of the cooling box is provided with mounting holes corresponding to the return tube, and the outer wall of the printing roller is slidably connected to the inner wall of the connecting tube.

[0026] In this embodiment, refer to Figure 1 、 Figure 2 and Figure 3As shown, a motor 9 is installed on the end face of the cooling box 1, and a stirring rod 10 is installed on the driving end of the motor 9. Stirring blades 11 are evenly distributed on the outer wall of the stirring rod 10. By installing the stirring rod 10 on the driving end of the motor 9, the stirring blades 11 can evenly stir the coolant inside the cooling box 1 to dissipate heat and cool it down.

[0027] In this embodiment, refer to Figure 1 、 Figure 2 、 Figure 3 ,and Figure 5 As shown, a drain pipe 12 is installed at the bottom of the cooling box 1 through a connecting groove, a control valve 13 is installed on the outer wall of the drain pipe 12, a suction pipe 14 is installed at the suction end of the water pump 4, a liquid inlet 15 is installed on the end surface of the cooling box 1, and a control valve 13 is installed on the outer wall of the drain pipe 12. When the temperature of the coolant in the cooling box 1 drops, the control valve 13 is opened to allow the coolant inside the cooling box 1 to flow into the liquid storage tank 2;

[0028] In this embodiment, refer to Figure 1 、 Figure 2 ,and Figure 3 As shown, a first glass window 16 is provided on the front of the cooling box 1 through the connecting groove, a liquid outlet 17 is provided on the front of the liquid storage tank 2, a second glass window 18 is provided on the front of the liquid storage tank 2 through the connecting groove, and a control panel 19 is installed on the end face of the cooling box 1.

[0030] In this embodiment, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the side wall of the liquid storage tank 2 is provided with mounting holes corresponding to the liquid infusion tube 5, the side wall of the cooling box 1 is provided with mounting holes corresponding to the return pipe 7, and the outer wall of the printing roller 6 is slidably connected to the inner wall of the connecting tube 801;

[0031] Working principle: When the printing roller cooling device for the printing device which is easy to maintain is in use, the motor 9 is first driven to move through the control panel 19. The motor 9 drives the stirring rod 10 to move and drives the stirring blade 11 to move, so that the coolant in the cooling box 1 can quickly reduce the temperature. When the temperature in the cooling box 1 is reduced, the control valve 13 is opened, and the control valve 13 drives the discharge pipe 12 to move, so that the coolant in the cooling box 1 reaches the inside of the liquid storage tank 2. Then the water pump 4 is driven to move through the control panel 19, and the water pump 4 drives the water suction pipe 14 to move, so that the coolant in the liquid storage tank 2 flows into the infusion pipe 5 through the water suction pipe 14, and then flows into the printing roller 6 through the infusion pipe 5, and flows into the return pipe 7 through the printing roller 6, and finally returns to the inside of the cooling box 1. When the printing roller 6 needs to be disassembled, the sliding sleeve 804 is first slid in the direction of the spring 803 and squeezes the spring 803, so that the sliding sleeve 804 and the limiting bead 807 are no longer in contact. , and then the connecting tube 801 is driven to move by the limiting sleeve 802, so that the limiting bead 807 is no longer in contact with the connecting hole 805, thereby separating the printing roller 6 and the connecting tube 801, achieving the effect of quick disassembly. When it needs to be installed, the printing roller 6 is slid into the inner wall of the connecting tube 801, so that the connecting hole 805 and the limiting bead 807 are in contact, and then the sliding sleeve 804 is released. The sliding sleeve 804 can quickly contact the limiting bead 807 through the reset function of the spring 803, thereby achieving the limiting effect and achieving the effect of quick installation. By setting a quick-release and quick-install mechanism, the sliding sleeve 804 can quickly return to its original position by utilizing the reset effect of the spring 803, and the limiting effect of the limiting bead 807 is utilized to make the connecting tube 801 and the printing roller 6 more stably connected, thereby solving the problem that the existing device does not have a quick-release and quick-install structure for the printing roller, which is inconvenient for maintenance of the printing roller, achieving the effect of easy disassembly and assembly, and improving work efficiency.
