Technical Field

[0001] This application relates to the technical field of labeling devices for external labeling machines, and in particular to a labeling device for an external labeling machine. Background Technology

[0002] Outer packaging machines are generally used to pack inner-packaged goods into medium or large boxes, bags, containers, or cans. After packaging, they mark the outer surface with symbols, stamps, product names, trademarks, etc., and give it a certain shape. Their main function is to ensure the safety of goods in circulation and facilitate loading, unloading, transportation, storage, and safekeeping. During the packaging process, outer packaging machines need to use labeling devices to label the packaging boxes, giving them unique characteristics and making them convenient to use.

[0003] Existing labeling machines label material boxes by placing the boxes on a support plate, then pressing the labeling mechanism onto the boxes to adhere the labels, and then manually replacing the boxes with the next ones, repeating this process.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing labeling machines cannot automatically apply labels during use and require adjustment of the material box position, which easily leads to low work efficiency during use. Utility Model Content

[0007] Optionally, the outer surface of the fixed base is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a first push plate, the outer surface of the first push plate meshes with a connecting toothed plate, and the upper surface of the first push plate is fixedly connected to a second push plate.

[0008] Optionally, a spring is fixedly connected to the inner wall of the slide, and the other end of the spring is fixedly connected to the first push plate.

[0009] Optionally, the upper surface of the fixing frame is rotatably connected to a first connecting post, two second connecting posts, a third connecting post, and a fourth connecting post. A label strip is provided above the fixing frame, and the outer surface of the label strip is rotatably connected to the first connecting post, the two second connecting posts, and the third connecting post.

[0010] Optionally, the outer surface of the label tape is fixedly connected to the label body and the wrapping tape, and the outer surface of the wrapping tape is rotatably connected to both the first connecting post and the fourth connecting post.

[0011] Optionally, a second motor is fixedly installed on the outer surface of the fixing frame, and a transmission mechanism is fixedly connected to the output end of the second motor.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This invention comprises a first motor, a rotating wheel, a triangular plate, a connecting toothed plate, a spring, a first push plate, and a pulley. The first motor rotates at a constant speed, causing the rotating wheel to drive the triangular plate to rotate along its central axis. During this process, the pulley slides on the rotating wheel until it contacts the triangular plate. Then, under the obstruction of the triangular plate, the pulley drives the connecting toothed plate to rotate around the central axis connecting the connecting toothed plate and the fixed base. The engagement of the connecting toothed plate with the first push plate pushes the first push plate horizontally. The spring is then compressed. When the first push plate has completely passed, the spring's rebound force resets the first push plate. This cycle repeats, thus achieving the effect of automatically attaching labels to parcel boxes through the cyclical movement of the first push plate. This invention incorporates components such as a cylinder, a limiting rod, a connecting plate, a second motor, and a transmission mechanism. The second motor drives the transmission mechanism to rotate at a constant speed, allowing material boxes placed on the transmission mechanism to be transported at a uniform speed. The cylinder's activation causes the limiting rod to slide vertically along the connecting plate, thereby adjusting the distance between adjacent material boxes. This achieves the effect of uniform label application and consistent label placement by adjusting the spacing between the material boxes. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0021] This application discloses an external labeling device. For example... Figure 1 , Figure 3 , Figure 4 As shown, the device includes a fixed frame 1. A second motor 20 is fixedly mounted on the outer surface of the fixed frame 1. A transmission mechanism 21 is fixedly connected to the output end of the second motor 20. A screw 18 is threadedly connected to the inner wall of the fixed frame 1. A third push plate 19 is rotatably connected to one end of the screw 18 near the fixed frame 1. The outer surface of the third push plate 19 is slidably connected to the fixed frame 1. When the second motor 20 is started, it drives the transmission mechanism 21 to start running, and the material box can be transported through the transmission mechanism 21. When the screw 18 is rotated, the screw 18 drives the third push plate 19 to slide horizontally along the fixed frame 1. The horizontal sliding of the third push plate 19 can constrain the position of material boxes of different sizes.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixed base 2 is fixedly connected to the upper surface of the fixed frame 1. A sliding groove is provided on the outer surface of the fixed base 2. A first push plate 7 is slidably connected to the inner wall of the sliding groove. The first push plate 7 can slide horizontally in the sliding groove.

[0023] Please see Figure 3 , Figure 4The outer surface of the first push plate 7 meshes with the connecting toothed plate 6. The upper surface of the first push plate 7 is fixedly connected to the second push plate 10. The inner wall of the slide is fixedly connected to the spring 8. The other end of the spring 8 is fixedly connected to the first push plate 7. The horizontal sliding of the first push plate 7 will drive the second push plate 10 to move horizontally. The material box can be labeled by the horizontal movement of the second push plate 10. When the first push plate 7 slides horizontally toward the fixed frame 1, the spring 8 begins to compress. When there is no external force, the spring 8 pushes the first push plate 7 to reset under the action of its rebound force.

[0024] Please see Figure 4 A first motor 3 is fixedly installed on the outer surface of the fixed base 2. A rotating wheel 4 is fixedly connected to the output end of the first motor 3. A triangular plate 5 is fixedly connected to the outer surface of the rotating wheel 4. When the first motor 3 starts, it will drive the rotating wheel 4 to start rotating. The rotation of the rotating wheel 4 will drive the triangular plate 5 to rotate around the central axis of the rotating wheel 4.

[0025] Please see Figure 4 A connecting toothed plate 6 is rotatably connected to the upper surface of the fixed base 2, and a pulley 9 is fixedly connected to the bottom surface of the connecting toothed plate 6. The outer surface of the pulley 9 is rotatably connected to the triangular plate 5, and the outer surface of the pulley 9 is rotatably connected to the rotating wheel 4. When the rotating wheel 4 rotates, the pulley 9 will slide around the surface of the rotating wheel 4. When the pulley 9 contacts the triangular plate 5, the pulley 9 will slide along the outer surface of the triangular plate 5. At this time, the pulley 9 will drive the connecting toothed plate 6 to rotate around the central axis at the connection point with the fixed base 2. In this way, the first push plate 7 is pushed to slide horizontally through the meshing of the connecting toothed plate 6 and the first push plate 7 until it has completely passed the triangular plate 5. Then, the first push plate 7 is reset by the rebound force of the spring 8. This cycle continues.

[0026] Please see Figure 2 , Figure 3 The upper surface of the fixing frame 1 is rotatably connected to a first connecting post 11, two second connecting posts 12, a third connecting post 13, and a fourth connecting post 14. A label tape 15 is provided above the fixing frame 1. The outer surface of the label tape 15 is rotatably connected to the first connecting post 11, the two second connecting posts 12, and the third connecting post 13. By wrapping the label tape 15 around the first connecting post 11, then around the two second connecting posts 12, and finally around the third connecting post 13, the first connecting post 11, the two second connecting posts 12, the third connecting post 13, and the fourth connecting post 14 will rotate simultaneously, controlled by the PLC circuit inside the fixing frame 1.

[0027] Please see Figure 2 , Figure 3The label body 17 and the wrapping tape 16 are fixedly connected to the outer surface of the label tape 15. The outer surface of the wrapping tape 16 is rotatably connected to the first connecting post 11 and the fourth connecting post 14. The wrapping tape 16 can protect the label body 17. The adhesive side of the label body 17 faces the wrapping tape 16. The label body 17 and the label tape 15 have a certain connection. The wrapping tape 16 separates from the label tape 15 and wraps around the fourth connecting post 14. At this time, the label body 17 is exposed, which facilitates the bonding of the label body 17 to the material box.

[0028] Please see Figure 1 , Figure 2 A fixed plate 24 is fixedly connected to one end of the fixed frame 1 near the second motor 20. A cylinder 22 is fixedly installed on the outer surface of the fixed plate 24. A limit rod 23 is fixedly connected to the output end of the cylinder 22. The outer surface of the limit rod 23 is slidably connected to the fixed plate 24. The cylinder 22 is controlled by the PLC circuit inside the fixed frame 1. When the cylinder 22 is started, it will drive the limit rod 23 to slide vertically in the fixed plate 24. When the material box is placed on the transmission mechanism 21, the transmission mechanism 21 will transport the material box. Then, the material box can be separated by the limit rod 23. The limit rod 23 can block or release the material box according to the distance between two adjacent material boxes, so as to keep the distance between the material boxes equal. Through its cooperation with the transmission mechanism 21 and the second push plate 10, the label is continuously and stably attached.

[0029] The implementation principle of the labeling device for an external labeling machine according to this application embodiment is as follows: First, the material box is placed on the transmission mechanism 21. Then, the cylinder 22 is controlled by the PLC to run, and it drives the limit rod 23 to slide vertically within the fixed plate 24, thereby controlling the distance between two adjacent material boxes. By rotating the screw 18, it drives the third push plate 19 to slide horizontally, thereby limiting the material box according to different sizes, preventing the material box from shifting due to the pushing force during the labeling process. Then, the first motor 3 is started, which drives the rotating wheel 4 to start rotating. The rotation of the rotating wheel 4 drives the triangular plate 5 to rotate around the central axis of the rotating wheel 4. The sliding of the pulley 9 on the rotating wheel 4 and the triangular plate 5, and the connecting toothed plate The engagement of the first push plate 6 with the first push plate 7 allows the first push plate 7 to drive the second push plate 10 to slide horizontally. At this time, the rebound force of the spring 8 can cause the second push plate 10 to move back and forth in a cycle. The second push plate 10 pushes the label tape 15 to make the label body 17 adhere to the material box. During this process, the rotation of the first connecting post 11, the two second connecting posts 12, the third connecting post 13 and the fourth connecting post 14 will cause the label tape 15 to separate from the wrapping tape 16, making it easier to adhere the label body 17. By controlling the rotation of the first connecting post 11, the two second connecting posts 12, the third connecting post 13 and the fourth connecting post 14, as well as the cooperation between the first motor 3 and the second motor 20, this device can automatically label.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
