Technical Field

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

[0002] Packaging bags are bags used in daily life and business activities to hold, cover or wrap items. In order to increase the value of goods and their use, as well as to promote products or manufacturers, packaging bags are usually printed with text or patterns. When packaging bags are printed on both sides, a flipping device is needed to turn the packaging bags over.

[0003] Existing packaging bag printing flipping devices have the printing mechanism installed at the top of the printing base frame. After printing one side of the packaging bag, it is necessary to manually flip the packaging bag before printing the other side. However, flipping the packaging bag is slow and requires time to lay it out neatly, which is not convenient for automatic flipping of the packaging bag for printing.

[0004] Therefore, a flipping device for printing packaging bags is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as slow bag flipping, time-consuming neat laying, and inconvenience for automatic bag flipping for printing. Therefore, this invention proposes a bag flipping device for printing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a flipping device for printing packaging bags, including a printing base frame, a lifting frame installed inside the printing base frame, a lifting mechanism provided between the lifting frame and the printing base frame, a printing table movably installed inside the lifting frame, and a clamping mechanism installed on the surface of the printing table;

[0008] The lifting mechanism includes a lifting plate, which is fixed at both ends of the lifting frame and slidably installed inside the printing base frame;

[0009] The clamping mechanism includes a clamping plate, which is elastically mounted on both sides of the printing table, and an anti-slip pad is bonded to its inner side.

[0010] Furthermore, the printing base frame has lifting grooves on both sides inside, the lifting plate slides into the lifting groove, the central rotating hole has a threaded hole structure, the lifting plate has a rectangular plate structure and is horizontally set, and the lifting groove has a rectangular groove structure and is vertically set.

[0011] Furthermore, the lifting groove has a first rotating rod that rotates through it, and the first rotating rod rotates through the rotating hole. A first motor is installed at the top of the first rotating rod, and the first motor is fixedly installed at both ends of the top of the printing base frame.

[0012] Furthermore, the lifting frame is a rectangular frame structure and is horizontally arranged. A second rotating rod is fixedly passed through the middle of the printing table. One end of the second rotating rod rotates through the middle of both sides of the lifting frame, and a second motor is installed at one end. The second motor is fixedly installed in the middle of the outer side of the lifting frame. A moving slot is opened on one side of the printing bottom frame, and the second motor slides into the moving slot.

[0013] Furthermore, the printing table is a rectangular plate structure, with a sliding groove inside and near the second rotating rod. A sliding plate slides through the sliding groove, and the two ends of the sliding plate have first connecting holes.

[0014] Furthermore, a first connecting rod is fixed to both sides of one end of the second rotating rod. The first connecting rod slides through the first connecting hole. The first connecting rod has a threaded rod structure and the gap is set between the lifting frame and the printing table. A first nut is connected to its surface. The first nut is located on both sides of the sliding plate.

[0015] Furthermore, the sliding plate is a rectangular plate structure with second connecting rods fixed at both ends. The gap between the second connecting rods is set on both sides of the printing table, and the second connecting rod is a threaded rod structure.

[0016] Furthermore, the clamping plate has second connecting holes at both ends, the second connecting rod slides through the second connecting holes, the top end of the second connecting rod is connected to a second nut, and a spring is sleeved on the surface of the second connecting rod at the position between the clamping plate and the second nut.

[0017] The present invention provides a flipping device for printing packaging bags, which has the following advantages:

[0018] 1. This utility model installs a lifting frame at the top of the printing base frame. The lifting frame is driven to move up and down by a lifting plate and a first rotating rod, thereby driving the printing table inside the lifting frame to move up and down. The printing table can move to the top of the printing base frame to print packaging bags, or it can descend into the inside of the printing base frame for safe storage.

[0019] 2. In this invention, a sliding plate is movably mounted on the surface of the printing table via a sliding groove and a first connecting rod. Second connecting rods are fixed to the sides of both ends of the sliding plate. Clamping plates are elastically mounted on both sides of the printing table via the second connecting rods and springs. Therefore, when a packaging bag to be printed is placed on the surface of the printing table, the springs press the opening of the packaging bag firmly onto the printing table using the clamping plates and anti-slip pads. After printing on one side of the packaging bag by the printing mechanism, the second motor drives the printing table to rotate 180 degrees to a horizontal position via the second rotating rod, flipping the packaging bag over. This allows for printing on both sides of the packaging bag without the need for manual flipping. Furthermore, two packaging bags can be printed at both ends of the printing table, increasing the printing speed. Attached Figure Description

[0028] The lifting mechanism includes a lifting plate 10, which is fixed at both ends of the lifting frame 4 and slidably installed inside the printing base frame 1.

[0029] The printing base frame 1 has lifting grooves 9 on both sides inside. The lifting plate 10 slides into the lifting groove 9. The central rotating hole 22 is a threaded hole structure. The lifting plate 10 is a rectangular plate structure and is set horizontally. The lifting groove 9 is a rectangular groove structure and is set vertically.

[0030] The lifting groove 9 has a first rotating rod 8 inside it, which rotates through the rotating hole 22. The first rotating rod 8 is mounted on the top of the first motor 5, which is fixedly installed at both ends of the top of the printing base frame 1.

[0031] The lifting frame 4 is driven to move up and down by the lifting plate 10 and the first rotating rod 8, which in turn drives the printing table 6 inside the lifting frame 4 to move up and down. The printing table 6 can move to the top of the printing base frame 1 to print packaging bags, or it can descend into the printing base frame 1 for safe storage.

[0032] The clamping mechanism includes a clamping plate 7, which is elastically mounted on both sides of the printing table 6, and an anti-slip pad 20 is bonded to its inner side.

[0033] The lifting frame 4 is a rectangular frame structure and is set horizontally. The printing table 6 has a second rotating rod 11 fixedly passing through the middle. One end of the second rotating rod 11 rotates through the middle of both sides of the lifting frame 4, and a second motor 3 is installed at one end. The second motor 3 is fixedly installed in the middle of the outer side of the lifting frame 4. A moving slot 2 is opened on one side of the printing bottom frame 1, and the second motor 3 slides into the moving slot 2.

[0034] The printing table 6 is a rectangular plate structure. Inside it, near the second rotating rod 11, there is a sliding groove 13. A sliding plate 12 slides through the sliding groove 13. The two ends of the sliding plate 12 have first connecting holes 19.

[0035] The first connecting rod 14 is fixed on both sides of one end of the second rotating rod 11. The first connecting rod 14 slides through the first connecting hole 19. The first connecting rod 14 is a threaded rod structure, and the gap is set between the lifting frame 4 and the printing table 6. The surface of the first connecting rod is connected to the first nut 15, which is located on both sides of the sliding plate 12.

[0036] The sliding plate 12 is a rectangular plate structure, with second connecting rods 16 fixed at both ends. The second connecting rods 16 are spaced apart on both sides of the printing table 6 and are threaded rods.

[0037] The clamping plate 7 has second connecting holes 21 at both ends. The second connecting rod 16 slides through the second connecting holes 21. The top end of the second connecting rod 16 is connected to the second nut 17. A spring 18 is sleeved on the surface of the second connecting rod 16 at the position between the clamping plate 7 and the second nut 17.

[0038] The packaging bag to be printed is attached to both ends of the printing table 6, and the opening of the packaging bag is pressed onto the printing table 6 by the spring 18 moving the clamping plate 7 and the anti-slip pad 20. Therefore, after printing one side of the packaging bag by the printing mechanism, the second motor 3 drives the printing table 6 to rotate 180 degrees to the horizontal through the second rotating rod 11 and flips the packaging bag over. Thus, both sides of the packaging bag can be printed without manually flipping the packaging bag, and two packaging bags can be printed at both ends of the printing table 6, which improves the printing speed of the packaging bag.

[0039] Working method: By installing a lifting frame 4 at the top of the printing base frame 1, and the lifting frame 4 being driven to move up and down by the lifting plate 10 and the first rotating rod 8, the printing table 6 inside the lifting frame 4 can be moved up and down. The printing table 6 can be moved to the top of the printing base frame 1 to print packaging bags, or it can be lowered into the printing base frame 1 for safe storage.

[0040] On the surface of the printing table 6, a sliding plate 12 is movably mounted via a sliding groove 13 and a first connecting rod 14, and a second connecting rod 16 is fixed to the sides of both ends of the sliding plate 12. The clamping plate 7 is elastically mounted on both sides of the printing table 6 via the second connecting rod 16 and a spring 18. Thus, the packaging bag to be printed is fitted onto both ends of the printing table 6, and the opening of the packaging bag is pressed onto the printing table 6 by the spring 18 moving the clamping plate 7 and the anti-slip pad 20. Thus, after printing one side of the packaging bag by the printing mechanism, the second motor 3 drives the printing table 6 to rotate 180 degrees to the horizontal via the second rotating rod 11 and flips the packaging bag over. This allows printing on both sides of the packaging bag without the need for manual flipping, and allows printing on two packaging bags at both ends of the printing table 6, thus increasing the printing speed of the packaging bag.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
