Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a printing and overprinting device for paper packaging boxes. Background Technology

[0002] Overprinting, also known as master-slave printing, refers to printing different colors sequentially on the same substrate using multiple printing plates, ensuring that the colors and text completely overlap to form a complete color or multicolor printed product. Packaging boxes require the printing of specific patterns onto their surfaces during production. In the prior art, utility model patent application number 202222405861.0 discloses a printing device for food packaging boxes, mainly composed of a machine and a printing mechanism. When printing on the packaging box, the box is placed and fixed on the machine, and then the printing mechanism prints the pattern on the surface of the box. However, this method has the following problems: dust inevitably adheres to the surface of the packaging box during production, affecting the printing effect and making it inconvenient to use. Therefore, a printing device with the function of cleaning dust from the packaging box surface is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a paper packaging box printing and overprinting device that can clean the dust off the surface of the packaging box before printing, thus ensuring printing quality, and is convenient, reliable, and practical.

[0004] This utility model discloses a paper packaging box printing and overprinting device, including a base plate; it also includes a translation mechanism, a fixing mechanism, a cleaning mechanism, and a printing mechanism. The fixing mechanism is mounted on the base plate via the translation mechanism, which is used to move the fixing mechanism and fix the packaging box. The cleaning mechanism is located above the base plate and is used to clean the packaging box. The printing mechanism is mounted on the base plate and is located to the right of the cleaning mechanism, and it has a printing function. The translation mechanism and the printing mechanism are connected to an external controller, which controls their operation. When it is necessary to print a pattern on the surface of the packaging box... The packaging box is placed on the fixing mechanism and secured, with the side to be printed facing upwards. Then, the fixing mechanism moves the packaging box to the right via the translation mechanism. During this movement, the packaging box first passes under the cleaning mechanism, which cleans the dust from the top surface of the packaging box. After cleaning, the packaging box continues to move to the right with the fixing mechanism until it reaches the printing mechanism. Then, the printing mechanism prints the pattern on the top surface of the packaging box. This method cleans the dust from the packaging box surface before printing, ensuring printing quality. It is convenient to use and highly reliable and practical.

[0005] Preferably, the translation mechanism includes an electric slide rail A and a sliding plate. The electric slide rail A is fixedly installed on the base plate, and the sliding plate is provided on the electric slide rail A. The electric slide rail A is used to move the sliding plate left and right. The fixing mechanism is fixedly installed on the sliding plate. The electric slide rail A is connected to an external controller. When printing on the packaging box, if it is necessary to move the packaging box left and right, the electric slide rail A is opened. The electric slide rail A, through the sliding plate, causes the fixing mechanism to move the packaging box in the left and right direction, thus facilitating the left and right movement of the packaging box.

[0006] Preferably, the fixing mechanism includes a vacuum box, a vacuum pump, and a positioning frame. The vacuum box is fixedly installed on the upper end of the sliding plate. The vacuum box has a chamber inside, and the upper end of the vacuum box has multiple air holes communicating with the chamber. The vacuum pump is fixedly installed on the vacuum box, and the input end of the vacuum pump communicates with the chamber of the vacuum box. The positioning frame is fixedly installed on the upper end of the vacuum box. When fixing the packaging box, the packaging box is placed on the upper end of the vacuum box, and the packaging box is positioned by the positioning frame, with the side of the packaging box to be printed facing upwards. Then, the vacuum pump is turned on to create a negative pressure inside the chamber of the vacuum box, thereby causing the packaging box to be adsorbed and fixed on the upper end of the vacuum box. This facilitates the fixing of the packaging box.

[0007] Preferably, the cleaning mechanism includes a hoisting frame, a hydraulic cylinder, a push rod, a lifting plate, a fixed column, a sliding column, a spring, a fixed frame, and a dust-adhesive roller. The hydraulic cylinder is fixedly installed on the upper end of the hoisting frame, the push rod is slidably installed on the hoisting frame, and the upper end of the push rod is connected to the output end of the hydraulic cylinder. The lifting plate is fixedly installed on the lower end of the push rod, the fixed column is fixedly installed on the lifting plate, the upper part of the sliding column is slidably installed on the fixed column, the upper end of the spring is fixedly installed on the lifting plate, the fixed frame is fixedly installed on the lower ends of the sliding column and the spring, and the dust-adhesive roller is rotatably installed on the fixed frame. When printing on the packaging box, the packaging box is first moved below the dust-adhesive roller. Then, the hydraulic cylinder is opened, and the hydraulic cylinder, through the push rod, causes the lifting plate to lower the spring. The spring causes the fixed frame and the dust-adhesive roller to lower, so that the lower end of the dust-adhesive roller contacts the upper end of the packaging box. Then, the packaging box is moved to the right. During the rightward movement, the dust-adhesive roller fully adheres the dust off the upper surface of the packaging box, facilitating the cleaning of the upper surface of the packaging box and ensuring printing quality.

[0008] Preferably, the printing mechanism includes two sets of moving mechanisms, printing plate A, printing plate B, paint tank A, and paint tank B. Both sets of moving mechanisms are mounted on a base plate. Printing plate A and printing plate B are respectively mounted on the two sets of moving mechanisms. Paint tank A and paint tank B are both mounted on the base plate, and the upper ends of paint tank A and paint tank B are open. When printing on the packaging box, the packaging box is first moved below printing plate A. Then, the lower part of printing plate A is moved into paint tank A via the moving mechanism connected to printing plate A, allowing the lower part of printing plate A to pick up paint from paint tank A. Next, printing plate A is moved above the packaging box, and then lowered so that printing plate A contacts the upper end of the packaging box, printing the background color onto the upper end of the packaging box. Then, the packaging box is moved below printing plate B, and printing plate B picks up paint from paint tank B in the same manner. Finally, paint tank B contacts the upper end of the packaging box, printing the pattern onto the background color, completing the overprinting process and facilitating the printing of the packaging box.

[0009] Preferably, the moving mechanism includes an indexing plate, an electric slide rail B, a moving plate, a mounting plate, and a connecting rod. The indexing plate is fixedly mounted on the base plate. The electric slide rail B is mounted on the rotating end of the upper part of the indexing plate.

The mounting plate is fixedly mounted on the moving plate, and the connecting rod is fixedly mounted on the lower end of the mounting plate. Printing plate A and printing plate B are respectively fixedly mounted on the connecting rods of the two sets of moving mechanisms. When printing plate A or printing plate B is moved, the electric slide rail B is opened, and the electric slide rail B moves through... The movable plate allows the mounting plate to drive the connecting rod for height adjustment, thus adjusting the height of printing plate A or printing plate B. When printing plate A or printing plate B needs to be dipped in paint, the indexing plate is opened. The indexing plate drives the electric slide rail B and the movable plate to rotate. The movable plate, through the mounting plate, causes the connecting rod to rotate printing plate A or printing plate B, moving printing plate A or printing plate B above paint tank A or paint tank B. Then, it is lowered into paint tank A or paint tank B to dip in paint. This facilitates the movement of printing plate A or printing plate B. Both printing plates A and B are relief printing plates.

[0010] Preferably, it also includes a pointer, which is fixedly mounted on a sliding plate. A positioning line A and a positioning line B are provided on the base plate. Positioning line A is located below printing plate A, and positioning line B is located below printing plate B. During printing of the packaging box, the sliding plate causes the vacuum chamber to move the packaging box to the right. When the pointer on the sliding plate points to positioning line A, it indicates that the packaging box has moved below printing plate A, and then printing is performed on the packaging box using printing plate A. When the pointer points to positioning line B, the packaging box is located below printing plate B, and then printing is performed on the packaging box using printing plate B, thus facilitating the positioning of the packaging box.

[0011] Compared with the prior art, the advantages of this utility model are: the dust on the surface of the packaging box can be cleaned before printing, which ensures the printing quality, and it is convenient to use, reliable and practical. Attached Figure Description

[0020] like Figures 1 to 6The paper packaging box printing and overprinting device of this utility model includes a base plate 1, a translation mechanism, a fixing mechanism, a cleaning mechanism, and a printing mechanism. The fixing mechanism is mounted on the base plate 1 via the translation mechanism, which is used to move the fixing mechanism and fix the packaging box. The cleaning mechanism is located above the base plate 1 and is used to clean the packaging box. The printing mechanism is mounted on the base plate 1 and is located to the right of the cleaning mechanism, and has the function of printing. The translation mechanism and the printing mechanism are connected to an external controller, which controls their operation. When it is necessary to print a pattern on the surface of the packaging box 28, the packaging box 28 is placed... The packaging box 28 is fixed to the fixing mechanism, with the side to be printed facing upwards. Then, the fixing mechanism moves the packaging box 28 to the right via the translation mechanism. During the rightward movement, the packaging box 28 first passes under the cleaning mechanism, which cleans the dust from the top surface of the packaging box 28. After cleaning, the packaging box 28 continues to move to the right with the fixing mechanism until it reaches the printing mechanism. Then, the printing mechanism prints the pattern on the top surface of the packaging box 28. This mechanism can clean the dust from the surface of the packaging box 28 before printing, ensuring printing quality. It is convenient to use and has high reliability and practicality.

[0021] like Figure 1 and Figure 3 The translation mechanism includes an electric slide rail A2 and a sliding plate 3. The electric slide rail A2 is fixedly installed on the base plate 1, and the sliding plate 3 is provided on the electric slide rail A2. The electric slide rail A2 is used to move the sliding plate 3 left and right. The fixing mechanism is fixedly installed on the sliding plate 3. The electric slide rail A2 is connected to an external controller. When printing on the packaging box 28, if it is necessary to move the packaging box 28 left and right, the electric slide rail A2 is opened. The electric slide rail A2, through the sliding plate 3, causes the fixing mechanism to move the packaging box 28 in the left and right direction, thus facilitating the left and right movement of the packaging box 28.

[0022] like Figure 3 The fixing mechanism includes a vacuum chamber 4, a vacuum pump 5, and a positioning frame 6. The vacuum chamber 4 is fixedly installed on the upper end of the sliding plate 3. The vacuum chamber 4 has a chamber inside, and the upper end of the vacuum chamber 4 has multiple air holes communicating with the chamber. The vacuum pump 5 is fixedly installed on the vacuum chamber 4, and the input end of the vacuum pump 5 is connected to the chamber of the vacuum chamber 4. The positioning frame 6 is fixedly installed on the upper end of the vacuum chamber 4. When fixing the packaging box 28, the packaging box 28 is placed on the upper end of the vacuum chamber 4, and the packaging box 28 is positioned by the positioning frame 6, with the side of the packaging box 28 that needs to be printed facing upwards. Then, the vacuum pump 5 is turned on to create a negative pressure in the chamber of the vacuum chamber 4, thereby causing the packaging box 28 to be adsorbed and fixed on the upper end of the vacuum chamber 4. This facilitates the fixing of the packaging box 28.

[0023] like Figure 1 and Figure 4 The cleaning mechanism includes a hoisting frame 7, a hydraulic cylinder 8, a push rod 9, a lifting plate 10, a fixed column 11, a sliding column 12, a spring 13, a fixed frame 14, and a dust roller 15.

The fixed frame 14 is fixedly mounted on the lower ends of the sliding column 12 and the spring 13. The dust roller 15... The rotating frame 14 is mounted on the fixed frame; the hoisting frame 7 is fixedly hoisted on the workshop support; when printing on the packaging box 28, the packaging box 28 is first moved below the dust roller 15, and then the hydraulic cylinder 8 is opened. The hydraulic cylinder 8 causes the lifting plate 10 to drive the spring 13 to descend through the push rod 9. The spring 13 drives the fixed frame 14 and the dust roller 15 to descend, so that the lower end of the dust roller 15 contacts the upper end of the packaging box 28. Then the packaging box 28 is moved to the right. During the process of moving to the right, the dust roller 15 fully removes the dust from the upper surface of the packaging box 28, which facilitates the cleaning of the upper surface of the packaging box 28 and ensures the printing quality.

[0024] like Figure 1 , Figure 2 and Figure 5 The printing mechanism includes two sets of moving mechanisms, printing plate A21, printing plate B22, paint tank A23, and paint tank B24. Both sets of moving mechanisms are mounted on the base plate 1. Printing plate A21 and printing plate B22 are respectively mounted on the two sets of moving mechanisms. Paint tanks A23 and paint tank B24 are both mounted on the base plate 1, and the upper ends of paint tanks A23 and B24 are open. When printing on the packaging box 28, the packaging box 28 is first moved below printing plate A21. Then, the lower part of printing plate A21 is moved into paint tank A23 via the moving mechanism connected to printing plate A21. The lower part of printing plate A21 is dipped into the paint in paint box A23. Then, printing plate A21 is moved above packaging box 28 and then lowered so that printing plate A21 contacts the upper part of packaging box 28. The background color is printed on the upper part of packaging box 28 through printing plate A21. Then, packaging box 28 is moved below printing plate B22. In the same way, printing plate B22 is dipped into paint in paint box B24 and then contacts the upper part of packaging box 28. The pattern is printed on the background color through paint box B24, completing the overprinting and facilitating the printing of packaging box 28.

[0025] like Figure 1 , Figure 5 and Figure 6The moving mechanism includes an indexing plate 16, an electric slide rail B17, a moving plate 18, a mounting plate 19, and a connecting rod 20. The indexing plate 16 is fixedly mounted on the base plate 1. The electric slide rail B17 is mounted on the rotating end of the upper part of the indexing plate 16. The moving plate 18 is mounted on the electric slide rail B17 and is used to move the moving plate 18 up and down. The mounting plate 19 is fixedly mounted on the moving plate 18. The connecting rod 20 is fixedly mounted on the lower end of the mounting plate 19. Printing plates A21 and B22 are respectively fixedly mounted on the connecting rods 20 of the two moving mechanisms. When moving printing plates A21 or B22, the electric slide rail B17 is opened, and the electric slide rail B17 moves through the moving plate 18. The mounting plate 19 can drive the connecting rod 20 to adjust the height, thus adjusting the height of printing plate A21 or printing plate B22. When it is necessary to dip printing plate A21 or printing plate B22 into paint, the indexing plate 16 is opened. The indexing plate 16 drives the electric slide rail B17 and the moving plate 18 to rotate. The moving plate 18, through the mounting plate 19, causes the connecting rod 20 to rotate printing plate A21 or printing plate B22, so that printing plate A21 or printing plate B22 is rotated above paint tank A23 or paint tank B24, and then lowered into paint tank A23 or paint tank B24 to dip into paint. This facilitates the movement of printing plate A21 or printing plate B22. Both printing plates A21 and B22 are relief printing plates. Example

[0026] Based on embodiment 1, a pointer 25 is also included. The pointer 25 is fixedly mounted on the sliding plate 3. The base plate 1 is provided with positioning lines A26 and B27. Positioning line A26 is located below the printing plate A21, and positioning line B27 is located below the printing plate B22. When printing the packaging box 28, the vacuum box 4 moves the packaging box 28 to the right by the sliding plate 3.
