Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a packaging box printing device which is convenient for replacing a printing roller. Background Art

[0002] Package printing is printing on various packaging materials. It is to print decorative patterns, designs or words on the packaging to make the packaging box attractive, thereby conveying information and increasing sales. This includes: packaging bottles, packaging boxes and packaging cans, etc. Therefore, package printing is an indispensable part of packaging engineering. There are many kinds of packaging box printing devices currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a general packaging box printing device prints packaging boxes by using a printing roller. The general printing roller can only print one fixed pattern, and it is impossible to replace different printing rollers according to different printing needs. At the same time, the packaging boxes that have just been printed may have ink that is not dry. If they are directly stacked together, the printed patterns on the packaging boxes will be mixed together. In addition, if the packaging boxes are printed without limiting the position of the packaging boxes, the packaging boxes will move during the printing process, which will cause the position of the printed pattern to be inaccurate. Therefore, we propose a packaging box printing device that is easy to replace the printing roller to solve the above problems. Utility Model Content

At the same time, the packaging box that has just been printed may have ink that is not dry. If they are directly stacked together, the patterns printed on the packaging box will be mixed together. In addition, if the packaging box is printed without limiting the packaging box, the packaging box will move during the printing process, which will cause the position of the printed pattern to be inaccurate.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a packaging box printing device that is convenient for replacing a printing roller, comprising: a conveyor belt 1, a support frame 2, a printing roller body 3, a printing pattern 4, a fixing rod 5, a motor 6, a fixing ring 7, a rubber pad 8, an electric telescopic rod 9, a supporting plate 10, a packaging box body 11, a clamping plate 12, a pushing rod 13, a supporting rod 14, a lever 15, a fixing frame 16, an electric fan 17 and a bolt 18;

[0027] like Figure 1 and Figure 4As shown in the figure, a fixing rod 5 is fixedly installed through the right side of the inside of the support frame 2, and the fixing rod 5 is placed above the rubber pad 8 on the right side of the inside of the support frame 2. A fixing ring 7 is connected to the bottom of the rubber pad 8, and the fixing ring 7 and the support frame 2 are connected and fixed. First, the printing roller body 3 is inserted into the inside of the fixing rod 5 from the left side of the fixing rod 5 and engaged with the fixing rod 5. At this time, the left side of the printing roller body 3 is placed above the fixing ring 7 set on the left side of the support frame 2, and then the electric telescopic rod 9 is opened. The top of the electric telescopic rod 9 is connected and fixed by the support plate 10. When the electric telescopic rod 9 is started, the output end of the electric telescopic rod 9 will push the connected fixing ring 7 and rubber pad 8 to move downward, so that the fixing ring 7 and rubber pad 8 connected to the output end of the electric telescopic rod 9 and the fixing ring 7 and rubber pad 8 below the printing roller body 3 are connected. The fixed ring 7 and the rubber pad 8 are engaged and connected, and then fixed by the bolt 18, that is, the fixed ring 7 and the rubber pad 8 are symmetrically fixed to the upper and lower outer sides of the printing roller body 3, which makes the printing roller body 3 more firmly installed. When it is necessary to replace a different printing roller body 3, first unscrew the bolt 18, and then open the electric telescopic rod 9. The output end of the electric telescopic rod 9 will drive the connected fixed ring 7 and the rubber pad 8 to move upward. At this time, the fixed ring 7 and the rubber pad 8 symmetrically on the left and right outer sides of the printing roller body 3 will be separated. At this time, hold the left side of the printing roller body 3 and rotate it to disengage the right side of the printing roller body 3 and the fixed rod 5. In this way, the printing roller body 3 can be taken out from the inside of the support frame 2, so that different printing roller bodies 3 can be replaced at any time according to different work needs;

[0028] like Figure 2 , Figure 3 and Figure 5 As shown in the figure, after the printing roller body 3 is installed, the printing pattern 4 is installed on the outside of the printing roller body 3, the packaging box body 11 is placed above the conveyor belt 1, and the conveyor belt 1 is turned on. The conveyor belt 1 can transfer the packaging box body 11 from front to back to the bottom of the printing pattern 4, and the motor 6 connected to the right side of the fixing rod 5 is turned on. The motor 6 can rotate the printing roller body 3, the printing pattern 4 and the fixing rod 5, and the printing pattern 4 prints the packaging box body 11. When the packaging box body 11 moves to the bottom of the printing pattern 4, the lever is opened. The motor 6 connected in front of the lever 15 will make the lever 15 slide inside the push rod 13. Meanwhile, the push rod 13 is also located inside the support rod 14. The support rod 14 is fixedly connected to the conveyor belt 1 below. In addition, the inner side of the push rod 13 is fixedly connected to the clamping plate 12. When the lever 15 slides inside the push rod 13, the push rod 13 and the clamping plate 12 can be pushed to move left and right, so that the clamping plate 12 moves inward to firmly clamp the packaging box body 11, which is limited, thereby improving the accuracy of the position of the printed pattern 4.

[0029] like Figure 3As shown in the figure, after the printing of the packaging box body 11 is completed, the conveyor belt 1 will move the packaging box body 11 to the bottom of the fixed frame 16. A plurality of electric fans 17 are arranged at equal distances above the interior of the fixed frame 16. When the packaging box body 11 moves to the position below the fixed frame 16, the electric fan 17 is turned on, that is, the electric fan 17 can air-dry the printed pattern 4 on the packaging box body 11 to prevent the printed patterns from being mixed up when the packaging box bodies 11 are stacked together later.
