[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figures 1-4, an embodiment provided by the present utility model: A carton printing machine with the prevention of ink splashing phenomenon, including a housing 1. The housing 1 is the main part of the device for installing and protecting the internal structure. Inside the housing 1, an ink cartridge 8, an ink roller 11, and a printing roller 6 are respectively installed. The ink cartridge 8 is used to store ink. The ink roller 11 is in contact with the printing roller 6. The ink roller 11 can guide the ink to move towards the printing roller 6. The printing roller 6 is in contact with the cardboard to print the cardboard. A ink delivery pipe 4 is installed on the left side of the ink cartridge 8. The ink delivery pipe 4 passes through the inside of the installation shell 5. The ink delivery pipe 4 is arranged on the top of the ink roller 11. The ink delivery pipe 4 is used to transport the ink in the ink cartridge 8 to the ink roller 11. A control valve is installed inside the ink delivery pipe 4 to control the opening and closing of the ink delivery pipe 4. A cleaning component 9 is arranged inside the housing 1. The cleaning component 9 is used to adjust the ink on the surface of the ink roller 11. The cleaning component 9 includes a rotating shaft 904. The rotating shaft 904 is rotatably connected inside the housing 1. An installation shell 5 is installed on the outer circumference of the ink roller 11. The rotating shaft 904 is rotatably connected inside the installation shell 5. Rotating the rotating shaft 904 can adjust the inclination angle of the scraping plate 901. A scraping plate 901 is rotatably connected inside the installation shell 5. The scraping plate 901 is fixedly connected to the outer circumference of the rotating shaft 904. The scraping plate 901 is arranged on the outer circumference of the ink roller 11. The scraping plate 901 can scrape off the ink on the surface of the ink roller 11 to adjust the ink transferred from the ink roller 11 to the surface of the printing roller 6. A ratchet gear 903 is fixedly connected to the outer circumference of the rotating shaft 904. A baffle 905 is rotatably connected inside the housing 1. The bottom of the baffle 905 abuts against the ratchet gear 903. The bottom of the baffle 905 is inserted into the ratchet gear 903 to block the rotation of the ratchet gear 903 and thus fix the angle of the scraping plate 901. A second spring 902 is installed on the top side of the baffle 905. The top end of the second spring 902 is installed inside the housing 1. The second spring 902 can push the baffle 905 to rotate so that the baffle 905 is in close contact with the ratchet gear 903. A dial 2 is arranged inside the housing 1. A pointer is arranged inside the dial 2. The pointer is connected to the rotating shaft 904. The pointer can rotate with the rotating shaft 904 and cooperate with the dial 2 to display the inclination angle of the scraping plate 901.

[0035] Refer to Figure 1 , Figure 2 , a ventilation component 3 is arranged on the outer circumference of the housing 1. The ventilation component 3 is used to enhance the ventilation effect inside the housing 1. The ventilation component 3 includes a ventilation pipe 303. The ventilation pipe 303 is fixedly connected to the outer circumference of the housing 1. The ventilation pipe 303 is used to install a fan 301. A fan 301 is installed inside the ventilation pipe 303. The rotation of the fan 301 can drive the air flow. A plurality of uniformly distributed ventilation holes 302 are opened inside the housing 1. The fan 301 is arranged on the right part of the ventilation holes 302. The air flow can enter the inside of the housing 1 through the plurality of ventilation holes 302.

[0036] Refer to Figure 1 , Figure 2 and Figure 5, a filter assembly 7 is arranged inside the ventilation pipe 303. The filter assembly 7 is used to filter impurities in the air flow. The filter assembly 7 includes a filter plate 701. The filter plate 701 is arranged inside the ventilation pipe 303 and is used to filter impurities in the air flow. Installation blocks 704 are fixedly connected to both the upper and lower sides of the filter plate 701. The installation blocks 704 are used to install the clamping blocks 703. Two clamping blocks 703 are arranged inside the installation blocks 704. A first spring 702 is installed on one side of the clamping block 703. The first spring 702 is used to push the clamping block 703 to move. One end of the first spring 702 is installed inside the installation block 704. The left side of the clamping block 703 is slidably connected to the inside of the housing 1, and the right side of the clamping block 703 is slidably connected to the right side of the installation block 704. The clamping block 703 can connect the filter plate 701 and the ventilation pipe 303 to each other. A sealing plate 10 is fixedly connected to one side of the clamping block 703. Two installation grooves are formed inside the installation block 704. The outer periphery of the sealing plate 10 is slidably connected to the inside of the installation groove. Installing the sealing plate 10 can prevent impurities from entering the inside of the installation block 704 and blocking the movement of the clamping block 703. The installation groove is used to receive the sealing plate 10.

[0037] Working principle: When using this printing machine, after putting the cardboard into the housing 1, start the printing machine and start the control valve inside the ink delivery pipe 4 so that the ink inside the ink cartridge 8 enters the installation housing 5 through the ink delivery pipe 4 and contacts the ink roller 11. After the printing machine is started, the ink roller 11 and the printing roller 6 are driven to rotate. The rotation of the ink roller 11 can transport the ink to the printing roller 6, and the rotation of the printing roller 6 can print the cardboard. When it is necessary to adjust the amount of ink on the surface of the ink roller 11, the baffle 905 can be pressed. The baffle 905 rotates to separate the baffle 905 from the ratchet gear 903, and then the inclination angle of the scraping plate 901 is adjusted by rotating the rotating shaft 904, thereby adjusting the amount of ink scraped off the surface of the ink roller 11 by the scraping plate 901, preventing excessive ink on the surface of the ink roller 11 from causing ink droplets to fall on the surface of the cardboard.

[0038] During the printing process, the fan 301 can be started. The rotation of the fan 301 can drive the air flow to enter the housing 1 through the ventilation pipe 303 and a plurality of ventilation holes 302, thereby enhancing the ventilation effect inside the housing 1 and preventing the formation of an ink mist environment by the ink volatiles inside the equipment. When the air flow enters the ventilation pipe 303, the filter plate 701 can block dust from entering the inside of the ventilation pipe 303 along with the air flow. The dust adheres to the surface of the filter plate 701. When it is necessary to clean the surface of the filter plate 701, two adjacent clamping blocks 703 can be pressed to move towards each other, and then the filter plate 701 can be taken out of the ventilation pipe 303 for cleaning.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
