[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In order to improve the efficiency of carton printing, Figure 1-3 As shown, the utility model discloses a color printing paper box production printing mechanism, comprising:

[0022] The base 1 is provided with at least one group;

[0023] A belt conveyor 2 is arranged on the machine base 1;

[0024] The screen printing unit 3 is located above the belt conveyor 2 and is arranged on the machine base 1;

[0025] The correction part 4 is connected to the machine base 1 .

[0026] When in use, the machine base 1, the belt conveyor 2, the screen printing part 3 and the correction part 4 provide a set of printing mechanisms capable of continuous printing for the paper box, so that the paper box blanks with a fixed structure of a single or multiple paperboards can be continuously conveyed for printing processing, thereby improving the printing processing efficiency of the paper box.

[0027] In order to print the carton blank, for example, Figure 2 As shown, the utility model also includes that the screen printing unit 3 includes:

[0028] The printing tray 301 is connected to the machine base 1;

[0029] The Y-axis electric slide rail 302 is arranged on the machine base 1;

[0030] The X-axis electric slide rail 303 is arranged on the sliding block of the Y-axis electric slide rail 302;

[0031] The sliders 304 are provided in two groups and are slidably connected to the two ends of the X-axis electric slide rail 303 respectively;

[0032] A C-shaped holder 306 connected to the bottom of the slider 304;

[0033] The scraper 307 is disposed on the sliding block of the X-axis electric slide rail 303 .

[0034] When in use, place the graphic screen to be printed on the C-shaped holder 306, inject the required printing pigment onto the screen, and drive the scraper 307 to apply the printing pigment through the X-axis electric slide 303, so that the pigment passes through the mesh of the screen and prints on the top of the paper box blank.

[0035] For example, Figure 2 As shown, the utility model also includes that the slider 304 and the C-shaped holder 306 are both provided with a threaded tightening member 305 .

[0036] When in use, the slider 304 is tightened and fixed to the X-axis electric slide rail 303 through the corresponding threaded tightening piece 305, and the C-shaped clamping seat 306 tightens and fixes the two ends of the screen printing screen that enters through the corresponding threaded tightening piece 305.

[0037] In order to correct the printing position of the carton blank, for example, Figure 3 As shown, the utility model also includes that two groups of the correction parts 4 are provided, and the two groups of the correction parts 4 are provided on the diagonal lines of the printing tray 301 .

[0038] The correction part 4 comprises:

[0039] The cylinder 401 is arranged on the printing tray 301;

[0040] The right-angle sheet metal 402 is disposed on the output end of the cylinder 401 .

[0041] When in use, the cylinder 401 pushes out the right-angled sheet metal 402 so that the right-angled sheet metal 402 can push the diagonal corner of the paper box blank to make the screen printing unit 3 print the paper box blank more neatly.

[0042] The printing tray 301 horizontally penetrates the middle of the belt of the belt conveyor 2 , and both ends of the printing tray 301 are riveted to the machine base 1 .

[0043] The belt conveyor 2 is a step-by-step belt conveyor.

[0044] When the utility model is used, the required number of machine bases 1 are selected, and the belt conveyor 2 is assembled on the machine base 1. The paper box blanks to be printed are conveyed by the belt conveyor 2, so that the paper box blanks pass through the machine base 1 in sequence, and the screen printing unit 3 on the machine base 1 prints the passing paper box blanks in sequence to achieve color printing. After the paper box blanks reach the printing tray 301 area, the cylinder 401 pushes out the right-angle sheet metal 402, so that the right-angle sheet metal 402 pushes the diagonal corners of the paper box blanks. The screen printing unit 3 prints the carton blank more evenly, ensuring the quality of the carton printing. During printing, the graphic screen to be printed is placed on the C-shaped holder 306, and the required printing pigment is injected into the printing screen in advance. The scraper 307 is driven by the X-axis electric slide rail 303 to apply the printing pigment, so that the pigment passes through the mesh holes of the screen and prints on the top of the carton blank. After printing, the printing screen returns to its position until the next group of carton blanks are entered, and this cycle is repeated to complete the continuous printing operation of the carton blanks.
