Description

Technical Field

[0001] The utility model relates to a device for automatically sticking a label onto a packaging box, belonging to the technical field of packaging machinery. Background Art

[0002] After the product is packaged, one or more labels need to be affixed to a fixed position on the outer wall of the packaging box. Currently, label paper is affixed to the packaging box basically by hand, which is inefficient and labor-intensive.

[0003] For this reason, many automatic labeling devices have emerged. For example, the Chinese utility model patent "Automatic labeling, label changing and detection device" with the reference number ZL 201922052990.4 (authorization announcement number CN212023232U) can replace manual labeling, but it has the disadvantages of large overall volume and high manufacturing cost. At the same time, after labeling, there is still the disadvantage that the label paper is not flat and easily wrinkled. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a box labeling mechanism with small volume and low cost in view of the above technical status quo.

[0005] The utility model solves the above technical problems by adopting the following technical solution: a box labeling mechanism, characterized in that it includes

[0006] Work rack;

[0007] A label supply mechanism is provided on the aforementioned working frame and can be used to place roll-shaped labels;

[0008] A rotary cylinder is mounted on the work frame;

[0009] A labeling cylinder, which is telescopically arranged at the power output end of the aforementioned rotating cylinder; and

[0010] The suction cup is arranged at the power output end of the aforementioned labeling cylinder and can absorb the label paper from the label supply mechanism.

[0011] Furthermore, the labeling mechanism also includes a conveyor belt for placing the packaging boxes.

[0012] The conveyor belt is rotatably provided with rollers on both sides, which can ensure that the packaging box is kept in a certain state when it is output, so as to facilitate the subsequent processes.

[0013] Preferably, a connecting plate is provided at the power output end of the labeling cylinder, and a plurality of suction cups are arranged on the connecting plate at intervals.

[0014] Furthermore, the working frame is provided with a blowing mechanism which can blow the label paper pasted on the packaging box flat. The blowing mechanism is conducive to making the label paper flatter.

[0015] The blowing direction of the blowing mechanism is opposite to the moving direction of the conveyor belt. This arrangement is conducive to improving the blowing effect.

[0016] Preferably, the blowing mechanism comprises an air pipe and an air nozzle, the air inlet end of the air pipe can be connected to an external air source, and the air nozzle is arranged at the air outlet end of the air pipe.

[0017] Compared with the prior art, the utility model has the advantages that the rotating cylinder and the labeling cylinder cooperate with each other to complete the transfer of the label paper from the label supply mechanism to the packaging box and then bond the label paper to the outer wall of the packaging box. The structure is compact, the cost is low, and it is easy to control. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the box labeling mechanism in this embodiment includes a working frame 5, a label supply mechanism 2, a rotating cylinder 11, a labeling cylinder 12, a suction cup 14, a conveyor belt 4 and a blowing mechanism 3.

[0024] The label supply mechanism 2 is disposed on the work frame 5 and has a roll 22 for placing the rolled label 21; and can transport the label papers 104 one by one at intervals.

[0025] The rotating cylinder 11 is arranged on the working frame 5; the labeling cylinder 12 is telescopically arranged at the power output end of the rotating cylinder 11; the rotating cylinder 11 can drive the labeling cylinder 12 to rotate 90°.

[0026] The suction cup 14 is arranged at the power output end of the labeling cylinder 12, and can suck the label paper from the label supply mechanism 2. Specifically, the power output end of the labeling cylinder 12 is provided with a connecting plate 13, and the suction cup 14 is arranged on the connecting plate 13 in multiple intervals.

[0027] The conveyor belt 4 is used to place the packaging box below the rotating cylinder 11. Rollers 41 are rotatably provided on both sides of the conveyor belt 4.

[0028] Combination Figure 3 As shown, the blowing mechanism 3 is arranged on the working frame 5, and can blow the label paper attached to the packaging box flat, and the blowing mechanism 3 includes an air pipe 31 and an air nozzle 32, the air inlet end of the air pipe 31 can be connected to an external air source, and the air nozzle 32 is arranged at the air outlet end of the air pipe 31. The blowing direction of the blowing mechanism 3 in this embodiment is opposite to the moving direction of the conveyor belt 4.

[0029] Labeling process, combined with Figure 2 and Figure 4 As shown, the labeling cylinder 12 is in motion, the connecting plate 13 drives the suction cup 14 to move forward, sucking the label paper 10 on the label supply mechanism 2, and the labeling cylinder 12 retreats. The rotating cylinder 11 drives the labeling cylinder 12 to rotate 90°, and the labeling cylinder 12 extends out to adhere the label paper 10 to the outer wall of the packaging box. At the same time, the blowing mechanism 3 works to blow the label paper flat. The blowing direction of the blowing mechanism 3 is from front to back, which is opposite to the running direction of the conveyor belt 4.
