Description

Technical Field

[0001] This utility model relates to the field of packaging box labeling technology, and in particular to an adjustable-angle color printing packaging box labeling device. Background Technology

[0002] Color-printed packaging boxes are paper containers used to package goods. Through color printing technology, a variety of patterns, texts, and colors are presented on their surface to achieve functions such as protecting goods and promoting sales.

[0003] In existing technologies, color printing packaging box labeling equipment typically uses a fixed-angle labeling head. Different sizes and shapes of packaging boxes require significantly different angles for the labeling head. The fixed-angle labeling head results in extremely poor equipment versatility. If the type of packaging box needs to be changed, it is often necessary to replace the entire labeling equipment or spend a lot of time on complex mechanical modifications, leading to low production efficiency, high debugging costs, and insufficient practicality. Therefore, it is necessary to redesign an adjustable-angle color printing packaging box labeling equipment to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-angle color printing packaging box labeling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-angle color printing and labeling equipment for packaging boxes includes a conveying device. Multiple support legs are fixedly installed on the bottom wall of the conveying device. A bidirectional screw is rotatably mounted on the bottom wall of the conveying device via a movable frame. A first motor connected to the bidirectional screw is fixedly installed on the outer wall of the movable frame. Two movable sleeves are threadedly installed on the outer wall of the bidirectional screw via a limiting mechanism. Clamping plates are fixedly installed on the upper surfaces of both movable sleeves via a connecting mechanism. The upper surface of the movable frame has a movable opening that cooperates with the two connecting rods. An mounting plate is fixedly installed on the upper surface of the conveying device. The inner wall of the mounting plate is fixed by a lifting mechanism. A connecting frame is fixedly installed, and a rotating rod is rotatably installed inside the connecting frame. A second motor is fixedly installed at the end of the rotating rod. Two connecting blocks are fixedly installed on the outer wall of the rotating rod. Labeling heads are fixedly installed on the bottom walls of the two connecting blocks. A lifting frame is fixedly installed on the upper surface of the mounting plate through the connecting plate. A one-way screw is rotatably installed inside the lifting frame. A third motor connected to the one-way screw is fixedly installed on the upper surface of the lifting frame. A moving plate is threaded onto the outer wall of the one-way screw. A fixed frame is fixedly installed on the bottom wall of the moving plate through a connecting mechanism. A compaction roller is rotatably installed inside the fixed frame.

[0007] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the movable frame, the limiting rod sliding through the two movable sleeves.

[0008] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper end face of the movable sleeve, and the end of the connecting rod is fixedly connected to the outer wall of the clamping plate.

[0009] Preferably, the lifting mechanism includes an electric push rod fixedly installed on the inner wall of the mounting plate, and the telescopic end of the electric push rod is fixedly connected to the upper end face of the connecting frame.

[0010] Preferably, the connecting mechanism includes two connecting rods fixedly installed on the bottom wall of the movable plate, and the upper end faces of the two connecting rods are fixedly connected to the fixed frame.

[0011] Preferably, protective pads are fixedly installed on the inner walls of both clamping plates, and both protective pads are made of rubber.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a second motor, a rotating rod, and connecting blocks, the first motor drives the rotating rod to rotate. When the rotating rod rotates, it drives the labeling head to rotate through the two connecting blocks, which can realize the free rotation and adjustment of the labeling head. It can meet the labeling needs of various complex-shaped packaging boxes such as irregularly shaped packaging boxes and curved packaging boxes. By precisely adjusting the angle of the labeling head, it can ensure that the label is tightly attached and accurately positioned.

[0014] 2. By setting up components such as a bidirectional screw, a limiting rod, and clamping plates, the bidirectional screw can drive the moving sleeve to move through cooperation with the limiting rod when it rotates. When the moving sleeve moves, it can cooperate with the connecting rod to adjust the distance between the two clamping plates. This allows for the clamping and fixing of packaging boxes of different sizes, increasing the practicality of the overall equipment. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An adjustable-angle color printing and labeling equipment for packaging boxes includes a conveyor device 1. Multiple support legs 2 are fixedly installed on the bottom wall of the conveyor device 1. A bidirectional screw 4 is rotatably mounted on the bottom wall of the conveyor device 1 via a movable frame 3. A first motor 5, connected to the bidirectional screw 4, is fixedly installed on the outer wall of the movable frame 3. Two movable sleeves 7 are threadedly mounted on the outer wall of the bidirectional screw 4 via a limiting mechanism. The limiting mechanism includes a limiting rod 6 fixedly installed inside the movable frame 3. The limiting rod 6 slides through the two movable sleeves 7, serving as a guide and limiting rod to prevent the movable sleeves 7 from rotating or shifting during movement, ensuring that the two movable sleeves 7 move synchronously along a straight line, thereby achieving clamping. The plate 9 precisely clamps the packaging box. The upper surfaces of the two movable sleeves 7 are fixedly installed with clamping plates 9 through a connecting mechanism. The connecting mechanism includes a connecting rod 8 fixedly installed on the upper surface of the movable sleeve 7. The end of the connecting rod 8 is fixedly connected to the outer wall of the clamping plate 9. The inner walls of the two clamping plates 9 are fixedly installed with protective pads 10. Both protective pads 10 are made of rubber. The rubber protective pads 10 have good elasticity and wear resistance. When clamping the packaging box, they can provide sufficient friction to prevent the packaging box from sliding and effectively protect the surface of the packaging box, avoiding scratches, indentations and other damage caused by excessive clamping force. The upper surface of the movable frame 3 is provided with a movable opening that cooperates with the two connecting rods 8.

[0023] A mounting plate 11 is fixedly installed on the upper surface of the conveying device 1. A connecting frame 13 is fixedly installed on the inner wall of the mounting plate 11 via a lifting mechanism. The lifting mechanism includes an electric push rod 12 fixedly installed on the inner wall of the mounting plate 11. The telescopic end of the electric push rod 12 is fixedly connected to the upper surface of the connecting frame 13. A rotating rod 14 is rotatably installed inside the connecting frame 13. A second motor 15 is fixedly installed at the end of the rotating rod 14. Two connecting blocks 16 are fixedly installed on the outer wall of the rotating rod 14. Labeling heads 17 are fixedly installed on the bottom walls of both connecting blocks 16. The upper surface of the mounting plate 11... A lifting frame 19 is fixedly installed via a connecting plate 18. A one-way screw 20 is rotatably installed inside the lifting frame 19. A third motor 21 connected to the one-way screw 20 is fixedly installed on the upper end face of the lifting frame 19. A moving plate 22 is threadedly installed on the outer wall of the one-way screw 20. A fixed frame 24 is fixedly installed on the bottom wall of the moving plate 22 via a connecting mechanism. The connecting mechanism includes two connecting rods 23 fixedly installed on the bottom wall of the moving plate 22. The ends of the two connecting rods 23 are fixedly connected to the upper end face of the fixed frame 24. A compaction roller 25 is rotatably installed inside the fixed frame 24.

[0024] When using this utility model, the packaging box to be labeled is placed on the conveying device 1. The conveying device 1 starts to operate, moving the packaging box towards the labeling station. At this time, the first motor 5 installed on the moving frame 3 on the bottom wall of the conveying device 1 starts and drives the bidirectional screw 4 to rotate. Since the bidirectional screw 4 adopts a left-right symmetrical thread design, the two moving sleeves 7 move towards or away from each other along the bidirectional screw 4 under the guidance of the limiting rod 6. The moving sleeves 7 drive the clamping plate 9 to move synchronously through the connecting rod 8 until the rubber protective pad 10 stably clamps the packaging box and completes the automatic positioning. After the packaging box is fixed, the electric push rod 12 on the inner wall of the mounting plate 11 extends and retracts according to the preset program, driving the connecting frame 13 to rise and fall vertically and adjust the height of the labeling head 17. At the same time, the second motor 15 at the end of the rotating rod 14 drives the rotating rod 14 to rotate, driving the connecting block 16 and the labeling head 17 fixed on its bottom wall to rotate horizontally, realizing multi-angle adjustment to meet the labeling needs of different surfaces such as flat surfaces, inclined surfaces, and curved surfaces.

[0025] After the labeling head 17 completes the label application, the third motor 21 on the upper surface of the mounting plate 11 starts, driving the one-way screw 20 inside the lifting frame 19 to rotate, causing the moving plate 22 to move downward along the one-way screw 20. The moving plate 22 drives the fixed frame 24 and the internal compaction roller 25 to descend through the connecting rod 23. The compaction roller 25 rolls and compacts the label surface to eliminate air bubbles and wrinkles. After completing the labeling and compaction process, the first motor 5 reverses, the clamping plate 9 is released, the conveying device 1 sends out the finished product, and all components of the equipment are reset, waiting for the next operation instruction. The whole process realizes automated and high-precision labeling operation.
