[0031] like Figures 1 to 3 As shown, the present application provides a labeling structure for attaching a label to a material to be labeled. An embodiment of the labeling structure of the present application includes: a base 10, a moving part 20, a labeling part 30, a trigger member 40, and a controller; the moving part 20 includes a driving part and a push rod 21, the push rod 21 is movably arranged on the base 10, and the push rod 21 can move toward or away from the material to be labeled; the labeling part 30 can be floatingly arranged on the push rod 21, the labeling part 30 can be connected to the label, and the push rod 21 moves toward the material to be labeled to drive the labeling part 30 to move, so that the label can contact the material to be labeled; the trigger member 40 is arranged on the push rod 21, and the trigger member 40 is located on the side of the labeling part 30 away from the material to be labeled; the controller is connected to both the driving part and the trigger member 40; wherein the labeling part 30 can trigger the trigger member 40, so that the controller controls the movement of the push rod 21.
[0032] According to the technical solution of the present embodiment, the base 10 is used to carry the various components of the labeling structure. The moving part 20 includes a driving part and a push rod 21. The push rod 21 is movably arranged on the base 10. The driving part is connected to the push rod 21 and drives the push rod 21 to move toward or away from the material to be labeled. The labeling part 30 is arranged on the push rod 21. The labeling part 30 can be connected with a label. When it is necessary to paste a label on the material to be labeled, the push rod 21 is moved toward the material to be labeled, so that the labeling part 30 is also moved toward the material to be labeled until the labeling part 30 contacts the material to be labeled, so that the label is also contacted with the material to be labeled, so that the label is pasted on the material to be labeled; the labeling part 30 can be arranged floatingly, the trigger member 40 is arranged on the push rod 21 and is located on the side of the labeling part 30 away from the material to be labeled, the controller is connected to both the driving part and the trigger member 40, and when the labeling part After the labeling part 30 contacts the material to be labeled, the push rod 21 continues to move toward the material to be labeled. Since the labeling part 30 abuts against the material to be labeled, the labeling part 30 moves toward the triggering part 40 relative to the triggering part 40 until the labeling part 30 triggers the triggering part 40. In the process of the labeling part 30 moving toward the triggering part 40, the labeling part 30 continues to abut against the material to be labeled, so that the label on the labeling part 30 continues to abut against the material to be labeled, so that the label can be more firmly attached to the material to be labeled. When the labeling part 30 triggers the triggering part 40, the triggering part 40 sends a control signal to the controller, and the controller controls the driving part according to the control signal, so that the driving part drives the push rod 21 to move in a direction away from the material to be labeled, so that the labeling part 30 is separated from the material to be labeled, thereby completing the labeling operation of the material to be labeled. Therefore, the technical solution of this embodiment can effectively solve the problem of unstable label pasting in the related art.
[0033] It should be noted that, in the present embodiment, the driving part is a cylinder structure, one end of the push rod 21 is arranged in the cylinder structure, and the cylinder structure can drive the push rod 21 to perform reciprocating telescopic motion.
[0034] like Figure 1As shown, the trigger member 40 includes a mounting portion 41 and a first proximity switch 42 arranged on the mounting portion 41, the mounting portion 41 is arranged on the push rod 21, the first proximity switch 42 is located between the mounting portion 41 and the labeling portion 30, one of the mounting portion 41 and the labeling portion 30 is provided with a through hole 411, and the other of the mounting portion 41 and the labeling portion 30 is provided with a first guide rod 31 inserted in the through hole 411. Specifically, in the present embodiment, the mounting portion 41 is a plate-like structure, the first proximity switch 42 is inserted on the mounting portion 41, and a through hole 411 is provided at each of the four corners of the mounting portion 41. The number of the first guide rods 31 is also four and they are correspondingly inserted in one of the through holes 411. The first guide rods 31 are connected to the side of the labeling portion 30 away from the material to be labeled and can slide in the through hole 411, so as to realize the floating of the labeling portion 30 on the push rod 21, and also realize the position change of the labeling portion 30 relative to the first proximity switch 42. The first proximity switch 42 is located between the mounting portion 41 and the labeling portion 30, so that the first proximity switch 42 can be triggered by the labeling portion 30.
[0035] like Figure 1 As shown, the labeling structure further includes an elastic member 51 sleeved on the first guide rod 31. Specifically, the elastic member 51 is a compression spring, and the elastic member 51 is located between the mounting portion 41 and the labeling portion 30, and the two ends of the elastic member 51 are respectively arranged to abut against the mounting portion 41 and the labeling portion 30; when the labeling portion 30 is separated from the material to be labeled, the elastic member 51 applies a force toward the material to be labeled to the labeling portion 30, so that the labeling portion 30 is separated from the first proximity switch 42 and the labeling portion 30 can be maintained at a position separated from the first proximity switch 42.
[0036] like Figure 1 As shown, the labeling structure further includes a buffer 52 disposed on the mounting portion 41 and located between the mounting portion 41 and the labeling portion 30.

[0037] like Figure 1 As shown, the labeling structure further includes a guide block 53 disposed on the base 10 and a second guide rod 54 connected to the mounting portion 41, and the second guide rod 54 is slidably inserted in the guide block 53. Specifically, the second guide rod 54 and the guide block 53 are guided and matched to make the movement of the labeling portion 30 and the mounting portion 41 more stable.
[0038] like Figure 1As shown, a trigger block is provided on the second guide rod 54, and the labeling structure also includes a second proximity switch 55 and a third proximity switch 56 connected to the controller. In the moving direction of the push rod 21, the third proximity switch 56 is arranged close to the material to be labeled relative to the second proximity switch 55, and the trigger block is located between the second proximity switch 55 and the third proximity switch 56 and can trigger the second proximity switch 55 and the third proximity switch 56. When the push rod 21 moves toward the material to be labeled to the maximum stroke, the trigger block triggers the third proximity switch 56. Specifically, the second proximity switch 55 and the third proximity switch 56 are arranged on the base 10. The movement of the push rod 21 will drive the installation part 41 to move, thereby driving the second guide rod 54 to move, and then driving the trigger block to move. The trigger block moves between the second proximity switch 55 and the third proximity switch 56; when the labeling part 30 completes labeling of the material to be labeled, the first proximity switch 42 will be triggered and the controller will control the push rod 21 to move in the direction away from the material to be labeled. At this time, the trigger block will also move in the direction away from the material to be labeled, that is, the trigger block will move toward the second proximity switch 55 until the trigger block triggers the second proximity switch 55. After the second proximity switch 55 is triggered, it sends a control signal to the controller, and the controller controls the push rod according to the control signal sent by the second proximity switch 55. 21 stops moving in the direction away from the material to be labeled and moves in the direction close to the material to be labeled, so as to label the next material to be labeled; the function of the third proximity switch 56 is: when the first proximity switch 42 fails or the labeling unit 30 cannot trigger the first proximity switch 42, the push rod 21 moves toward the material to be labeled to its maximum stroke, so that the trigger block triggers the third proximity switch 56, so that the third proximity switch 56 sends a control signal to the controller, and the controller controls the push rod 21 to stop moving toward the material to be labeled and move toward the direction away from the material to be labeled according to the control signal sent by the third proximity switch 56, thereby ensuring that even if the first proximity switch 42 cannot send a control signal to the controller, the push rod 21 can continue to reciprocate.
[0039] like Figures 1 to 3 As shown, the labeling part 30 is a plate-shaped structure, and a plurality of negative pressure suction holes 32 are arranged on the side of the labeling part 30 facing the material to be labeled, and the negative pressure suction holes 32 are connected to the negative pressure source so that the negative pressure suction holes 32 can absorb the labels. Specifically, the negative pressure source is a negative pressure pump, which can make the negative pressure suction holes 32 generate an adsorption force, so that the labeling part 30 can stably absorb the labels.
[0040] like Figure 2 as well as Figure 3As shown, the labeling part 30 includes a detachable first plate 33 and a second plate 34, the first plate 33 is arranged near the material to be labeled, the negative pressure suction hole 32 is arranged through the first plate 33, and a groove 341 is arranged on the side of the second plate 34 near the first plate 33, the slot opening of the groove 341 is arranged correspondingly and connected with the negative pressure suction hole 32, and the groove 341 is connected with the negative pressure source. Specifically, through the arrangement of the groove 341, multiple negative pressure suction holes 32 are connected with the groove 341, so that multiple negative pressure suction holes 32 have adsorption force, and it is not necessary to make each negative pressure suction hole 32 connected with the negative pressure source through a connecting piece, so that the labeling part 30 has the advantages of easy processing and simple structure; in addition, the first plate 33 and the second plate 34 are connected together by bolts, and a sealing ring can also be arranged between the first plate 33 and the second plate 34 at the groove 341, so as to ensure the adsorption force of the negative pressure suction hole 32.
[0041] The present application also provides a labeling assembly, which includes: a conveyor belt 100, a labeling structure and a label brush structure 110, wherein the labeling structure is the above-mentioned labeling structure. The above-mentioned labeling structure can effectively solve the problem of unstable label pasting in the related art, and the labeling assembly with the above-mentioned labeling structure also has the above-mentioned advantages.
[0042] like Figure 4 As shown, the labeling structure and the label brushing structure 110 are both located on the first side of the conveyor belt 100. In the conveying direction of the conveyor belt 100, the label brushing structure 110 is located downstream of the labeling structure. Specifically, the conveyor belt 100 is used to transport a plurality of materials to be labeled, and the labeling structure is used to paste the label on the materials to be labeled. After the label is pasted on the materials to be labeled, the label brushing structure 110 makes the pasted label more firmly pasted. Specifically, in other embodiments, when all the labels are pasted on the same surface of the materials to be labeled, the label brushing structure can be set to swing, and the label brushing structure swings back and forth along the conveying direction of the conveyor belt. After the label brushing structure contacts the label, it swings back and forth to make the label more firmly pasted on the materials to be labeled, thereby preventing the label from falling off.
[0043] like Figure 4As shown, the label brushing structure 110 includes a brush part 1101, and the brush part 1101 can move toward or away from the material to be labeled, so that the brush part 1101 can apply a force to the label in the direction of the second side of the conveyor belt 100. Specifically, in this embodiment, the material to be labeled is a rectangular parallelepiped structure, and the label needs to be pasted on two mutually perpendicular sides of the material to be labeled, namely the first side and the second side. The first side is parallel to the conveying direction of the conveyor belt 100, and the second side is perpendicular to the conveying direction of the conveyor belt 100. The first side is arranged in parallel with the labeling part 30 of the labeling structure, so that the labeling part 30 can paste part of a label on the first side; then, the brush part 1101 moves toward the material to be labeled and can apply a force to the unpasted part of the label in the direction of the second side of the conveyor belt 100, so that the unpasted part of the label can be pasted on the second side, so that the label can be partially pasted on the first side and partially pasted on the second side, so as to meet different requirements for pasting labels.
[0044] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0047] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
