Description

Technical Field

[0001] This utility model relates to the field of ointment production, and in particular to a high-efficiency inkjet printing device for outer packaging boxes. Background Technology

[0002] Patent application number "202420905350.1", entitled "A Conveyor Line for Improving the Quality of Inkjet Printing on Outer Packaging Boxes of Ointments", describes a device that uses a conveyor line to transport and inkjet print on outer packaging boxes. Inkjet printing is performed after the outer packaging box is filled with the finished medicine. The filled outer packaging box has a cubic structure and is pushed out laterally from the side for inkjet printing. This method requires manual handling of the filled and shaped outer packaging boxes on the conveyor belt, resulting in high labor intensity (changing to flat, empty boxes would significantly reduce this labor intensity). Furthermore, the cubic structure of the outer packaging box occasionally changes direction when pushed around corners on the conveyor belt, causing errors in inkjet printing position and blurry characters (eliminating right-angle turns and replacing them with straight-line operation would eliminate this phenomenon and improve inkjet printing stability). Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a high-efficiency inkjet printing device for outer packaging boxes, which can improve inkjet printing efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The high-efficiency inkjet printing device for outer packaging boxes includes a roller conveyor line, with an inkjet printing device arranged above the roller conveyor line. A first pushing mechanism is set on one side of the inkjet printing device on the roller conveyor line, and a first positioning plate is set on the other side of the inkjet printing device on the roller conveyor line. Flat, unused outer packaging boxes are transported by the roller conveyor line. When passing the inkjet printing device, the inkjet printing device prints and marks vertically downwards.

[0005] The output end of the roller conveyor line is equipped with an outer packaging box receiving mechanism, which includes a roller receiving line and a lifting mechanism installed at the lower end of the roller receiving line.

[0006] The length of the roller receiving line is consistent with the length of the outer packaging box, and a third positioning plate is fixed at the output end of the roller receiving line.

[0007] The lifting mechanism is a scissor lift mechanism.

[0008] A second pushing mechanism is installed on one side of the roller receiving line in the horizontal direction, and a second positioning plate is set on the other side.

[0009] Both the first pushing mechanism and the second pushing mechanism include a fixed base, on which a first cylinder is mounted. The output end of the first cylinder drives a push rod to move. The push rod is positioned in the gap between the rollers of the roller conveyor line or the outer packaging box receiving mechanism and extends out partially.

[0010] The coding device is mounted and fixed by a bracket, which includes a vertical rod that is fixed to the coding device. The vertical rod is installed in the vertical hole of the cross clamp and locked. The horizontal rod passes through the horizontal hole of the cross clamp and is locked. The two ends of the horizontal rod are fixed to the support rod by the cross clamp.

[0011] This utility model provides a high-efficiency inkjet printing device for outer packaging boxes, which has the following technical effects: 1) By setting up a separate inkjet marking device that was originally located at the end of the packaging line; changing the original horizontal marking to vertical downward marking; and changing the original three-dimensional packaging box after packing to a flat outer packaging box with a flat structure before packaging, the marking is performed vertically downward because the outer packaging box is a folded and flat structure supported by the roller conveyor line. Compared with the existing method, it is not affected by the speed of the previous process of drug packaging. At the same time, the problem of blurry marking and other defects caused by vertical marking on the flat structure before use, compared with the horizontal marking on the three-dimensional structure after packaging, is basically solved.

[0012] 2) By adopting a movable outer packaging box receiving mechanism set on one side of the roller conveyor line, the marked outer packaging boxes can be stacked and collected for convenient subsequent use. Attached Figure Description

[0020] like Figures 1-3 As shown, a high-efficiency inkjet printing device for outer packaging boxes includes a roller conveyor line 1, which is driven to rotate by a chain conveyor mechanism 2 and a motor 3. An inkjet printing device 4 is arranged above the roller conveyor line 1 and is fixedly mounted by a bracket 5. An outer packaging box receiving mechanism 6 is installed at the end of the roller conveyor line 1. Unused outer packaging boxes 7 are flat and folded without adhesive at both ends. The unused outer packaging boxes 7 are placed into the roller conveyor line 1 from the input end. When they reach the inkjet printing device 4, a first pushing mechanism 8 on one side pushes the unused outer packaging box 7 onto a first positioning plate 9 on the other side. After the outer packaging box 7 is in place, the inkjet printing device 4 prints the production date, specifications, etc. Subsequently, the roller conveyor line 1 sends the marked outer packaging boxes 7 onto the outer packaging box receiving mechanism 6 for stacking. The outer packaging box receiving mechanism 6 is pushed by a second pushing mechanism 10 on one side. A second positioning plate 11 is fixed on the other side of the outer packaging box receiving mechanism 6. A third positioning plate 12 is fixed on one side of the second positioning plate 11 and at the end of the outer packaging box receiving mechanism 6. The third positioning plate 12 is connected to the second positioning plate 11 to form an L-shape. The second positioning plate 11 and the third positioning plate 12 can position the stacked outer packaging boxes 7 to ensure that each outer packaging box 7 is stacked neatly.

[0021] The coding device 4 is a conventional carton coding machine, such as the Domino A320 series. The point of application of the coding device 4 is downward.

[0022] like Figure 2 As shown, the bracket 5 includes a vertical rod 4.1 fixed to the upper end of the housing of the coding device 4. The vertical rod 4.1 passes through the vertical hole of the cross clamp 4.2 and is fastened with bolts. A horizontal rod 4.3 passes through the horizontal hole of the cross clamp 4.2 and is fastened with bolts. The two ends of the horizontal rod 4.3 are fixed to the support rod 4.4 by the cross clamp 4.2, and the support rod 4.4 is fixed to the ground.

[0023] The height of the coding device 4 can be adjusted up and down by loosening the bolt at the vertical rod 4.1; the horizontal position of the coding device 4 can be adjusted left and right by loosening the bolt at the horizontal rod 4.3.

[0024] like Figure 6 As shown, the first pushing mechanism 8 and the second pushing mechanism 10 have basically the same structure, both including a fixed base 8.1. A first cylinder 8.2 is installed on the fixed base 8.1. The output end of the first cylinder 8.2 drives the push rod 8.3 to move. The push rod 8.3 is located in the gap between the rollers of the roller conveyor line 1 or the outer packaging box receiving mechanism 6. The push rod 8.3 extends a certain length beyond the upper end of the roller. The push rod 8.3 moves along the axis of the roller and pushes the outer packaging box 7 to move laterally.

[0025] Furthermore, if multiple sets of push rods 8.3 need to be set, the bottom ends of each push rod 8.3 are connected by a connecting rod 8.4. The push rods 8.3 at both ends of the connecting rod 8.4 are slidably engaged with the guide rod 8.5, and the two ends of the guide rod 8.5 are fixed to the fixed base 8.1. That is, multiple sets of push rods 8.3 can be driven synchronously by a first cylinder 8.2 through the connecting rod 8.4; by setting the guide rod 8.5, multiple sets of push rods 8.3 can be guided to ensure the stability of multiple sets of push rods 8.3.

[0026] like Figure 4 As shown, the outer packaging box receiving mechanism 6 includes a roller receiving line 6.1. The roller receiving line 6.1 is a roller line without external drive, that is, it consists only of a frame and rollers, without the chain conveyor mechanism 2 and the motor 3. A lifting mechanism 6.2 is installed at the lower end of the frame of the roller receiving line 6.1. The lifting mechanism 6.2 can be a scissor lifting mechanism or a ball screw mechanism. Both scissor lifting mechanisms and ball screw mechanisms are existing technologies. This application uses a scissor lifting mechanism, which includes support rods 6.2.1 that are hinged to each other in the middle. The upper and lower ends of the two support rods 6.2.1 are both hinged to connecting seats 6.2.2. Among the two sets of connecting seats 6.2.2 at the upper end, the left connecting seat 6.2.2 is fixed to the frame of the roller receiving line 6.1, and the right connecting seat 6.2.2 is slidably engaged with the slide rod on the roller receiving line 6.1. Of the two sets of connecting seats 6.2.2 at the lower end, the left connecting seat 6.2.2 is fixed to the movable base 6.2.3, while the right connecting seat 6.2.2 is slidably engaged with the slide rod on the movable base 6.2.3. The slidable connecting seat 6.2.2 is driven to move by the second cylinder 6.2.4.

[0027] The lower part of the movable base 6.2.3 is equipped with casters 6.2.5 with brakes. The casters 6.2.5 facilitate the movement of this device and can be braked and fixed.

[0028] The length of the roller receiving line 6.1 is consistent with the length of the outer packaging box 7. That is, after the power provided by the roller conveyor line 1 makes the outer packaging box 7 fall completely on the roller receiving line 6.1, one side of the outer packaging box 7 is aligned with the inner side of the third positioning plate 12, and the other side is just detached from the roller conveyor line 1.

[0029] Working principle and process: A flat, unused outer packaging box 7 is manually placed at the input end of the roller conveyor line 1. The outer packaging box 7 moves forward driven by the rotation of the rollers. When it reaches the coding device 4, the infrared sensor 13 detects that the outer packaging box 7 is in position in the conveying direction (longitudinal). The roller conveyor line 1 stops. Then, the first cylinder 8.2 of the first pushing mechanism 8 extends, and the push rod 8.3 pushes the outer packaging box 7 to the first positioning plate 9 in the vertical conveying direction (lateral). At this time, the outer packaging box 7 is in position, and the coding device 4 performs coding. Subsequently, the roller conveyor line 1 starts and conveys the outer packaging box 7 to the outer packaging box receiving mechanism 6. Initially, the roller of the outer packaging box receiving mechanism 6 is at the same height as the roller conveyor line 1 or about 5 cm to 10 cm lower than the roller conveyor line. Subsequently, according to the thickness of the outer packaging box 7, after receiving a certain number of outer packaging boxes 7, the roller receiving line 6.1 lowers a certain height (for example, 10 cm each time). Since the length of the roller receiving line 6.1 is consistent with the length of the outer packaging box 7, when the outer packaging box receiving mechanism 6 is close to the roller conveyor line 1, all the power for the outer packaging box 7 to travel from the roller conveyor line 1 to the outer packaging box receiving mechanism 6 is provided by the roller conveyor line 1. When the front end of the outer packaging box 7 reaches the third positioning plate 12, and the end is conveyed by the roller conveyor line 1 and just leaves the roller conveyor line 1, the outer packaging box receiving mechanism 6 receives it in place. The second pushing mechanism 10 then pushes the outer packaging box 7 and attaches it to the second positioning plate 11. At this time, the long side (a) of the outer packaging box 7 is attached to the second positioning plate 11, and the wide side (b) of the outer packaging box 7 is attached to the third positioning plate 12, achieving stacked collection, which can then be directly transferred to the packaging line for use.
