Description

Technical Field

[0001] The utility model belongs to the technical field of labeling machines, and particularly relates to a label pressing device of a labeling machine. Background Art

[0002] In the modern logistics and packaging industry, the labeling process after the goods are packed and packaged is crucial, which is directly related to the identification, tracking and storage management efficiency of the goods. Traditional labeling machines have shown a high level of automation in labeling, and can complete the labeling work efficiently and accurately. However, with the diversification of commodity types and the non-uniformity of packaging specifications, traditional labeling machines face significant challenges in the labeling process.

[0003] Specifically, due to the difference in the number of packed goods, the sizes of boxes vary. Although the labeling machine can flexibly label boxes of different sizes, in the labeling process, due to the problem of fixed height or inconvenient adjustment of the traditional labeling method using a scanning plate and a pressing plate, it is often unable to fit tightly to the surface of boxes of different heights, resulting in false label pressure. This false pressure not only affects the firmness of the label, but also increases the risk of label falling off during subsequent transportation, which may lead to serious consequences such as loss of product information, wrong shipment or delay.

[0004] Therefore, it is necessary to design a more automated and intelligent label pressing device to cooperate with the labeling machine to achieve efficient and accurate label pressing operations. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a label pressing device for a labeling machine to solve the above-mentioned problems.

[0007] Furthermore, an elastic connecting portion is provided between the support rod and the roller seat.

[0008] Furthermore, the elastic connection part includes a rubber rod and a spring, the two ends of the rubber rod are respectively connected to the support rod and the roller seat, and the spring is sleeved on the rubber rod and the two ends are respectively connected to the support rod and the roller seat.

[0009] Furthermore, the elastic pressing sheet is a stainless steel spring sheet, and the surface is coated with a silicone layer.

[0010] Furthermore, the thickness of the elastic pressing sheet gradually decreases from the inner end to the outer end.

[0011] Furthermore, a rotatably connected adjusting screw is provided at the telescopic end of the electric telescopic rod, a "C-shaped" bracket hinged to the support rod is screwed on the adjusting screw, and a handle insertion hole is opened on the adjusting screw.

[0012] Compared with the existing technology, the label pressing device effectively solves the problems of false pressing and falling off of labels on boxes of different sizes by automatically adjusting the height of the pressure roller and the elastic pressure sheet design, improves the firmness of label pasting and logistics efficiency, protects the surface of the box, reduces the complexity of operation, and realizes efficient and precise automated label pressing operations.

[0016] In order to better understand the present invention, Figure 1 and Figure 2 The implementation modes of the present utility model will be explained in detail.

[0017] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0018] The utility model discloses a label pressing device for a labeling machine, comprising a mounting plate 1, wherein the mounting plate 1 is designed with a plurality of mounting holes 2, so as to be stably mounted at an appropriate position of the labeling machine. Below the mounting plate 1, a support rod 3 is connected in a hinged manner, and the support rod 3 is a key component for supporting and adjusting the height.

[0019] On the left and right sides of the support rod 3, a distance sensor 4 and an electric telescopic rod 5 are respectively arranged on the mounting plate 1. The telescopic end of the electric telescopic rod 5 is connected to the support rod 3 in an articulated manner to increase the flexibility and stability of adjustment. The detection head of the distance sensor 4 faces downward, and is used to detect the height information of the box on the conveyor belt in real time, and transmit this information to the control system for subsequent adjustment of the position of the pressure roller 7. The electric telescopic rod 5 drives the support rod 3 to rotate around the hinge point through its telescopic function according to the instructions issued by the control system, and adjusts the height of the bottom end of the support rod 3, thereby achieving adaptation to boxes of different heights.

[0020] A roller seat 6 is fixed at the bottom end of the support rod 3, and a pressing roller 7 is rotatably connected to the roller seat 6. A circle of arc-shaped elastic pressing sheets 8 are evenly arranged around the pressing roller 7. When the pressing roller 7 rotates, these elastic pressing sheets 8 can closely fit the surface of the box body to evenly and effectively compact the label.

[0021] In order to improve the compaction effect, the elastic pressing sheet 8 is made of stainless steel spring sheet, and the surface is also wrapped with a layer of silicone to increase friction and protect the surface of the box from being scratched. In addition, the thickness of the elastic pressing sheet 8 is designed to be gradually thinner from the inner end to the outer end. This design allows the edge of the pressing sheet to gradually apply greater pressure during the rotation of the pressing roller 7, further improving the uniformity and firmness of the compaction.

[0022] In order to further enhance the adaptability and stability of the pressure marking device, an elastic connection part is also provided between the support rod 3 and the roller seat 6. The elastic connection part includes a rubber rod 10 and a spring 11 sleeved on the rubber rod 10. The two ends of the rubber rod 10 and the spring 11 are respectively connected to the support rod 3 and the roller seat 6. When the pressure roller 7 encounters boxes of different heights, the elastic connection part can absorb part of the impact force to prevent the pressure roller 7 from directly hitting the box and causing damage, and also improve the buffering capacity and stability of the device.

[0023] In order to more accurately adjust the height of the pressing roller 7, a rotatably connected adjusting screw 12 is also provided at the end of the telescopic end of the electric telescopic rod 5. A "C-shaped" bracket 13 is screwed on the adjusting screw 12, and the bracket 13 is hinged with the support rod 3. By rotating the adjusting screw 12, the height of the pressing roller 7 can be fine-tuned to adapt to more subtle differences in the height of the box. A handle socket is also provided on the adjusting screw 12 to facilitate the operator to use tools for rotation operation.

[0024] The usage and principle of this utility model:

[0025] First, install the device at the appropriate position of the labeling machine through the mounting hole 2. Then, start the labeling machine for normal labeling operation. When the label is pasted on the box, the distance sensor 4 will detect the height information of the box in real time and transmit this information to the control system. According to the detected height of the box, the control system controls the telescopic end of the electric telescopic rod 5 to extend, driving the support rod 3 to rotate clockwise around the hinge point, so that the pressure roller 7 can be lowered to a suitable height. Next, start the motor 9 to drive the pressure roller 7 to rotate, and the elastic pressure sheet 8 fits tightly to the surface of the box and compacts the label. After compaction is completed, the telescopic end of the electric telescopic rod 5 shrinks and resets, and drives the support rod 3 to rotate counterclockwise around the hinge point, so that the pressure roller 7 rises and resets, preparing for the next label pressing operation. During the whole process, the operator only needs to monitor the operating status of the equipment, and can achieve efficient and accurate label pressing operations without complicated operations.
