[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This invention provides a laser offline coding device for cigarette boxes, comprising: a conveyor belt 1, a coding device 2, and a detection device 3. The conveyor belt 1 transports cigarette boxes along the X-axis, moving them from one end to the other. The coding device 2 is located on one side of the conveyor belt 1 and performs laser coding on the cigarette boxes on the conveyor belt 1.

[0033] The detection device 3 includes a fixed frame 31, a sliding plate 32, a slider 33, a detection camera 34, and a strip light source 35. The fixed frame 31 is installed on one side of the conveyor belt 1. The sliding plate 32 is slidably installed on one side of the fixed frame 31 and can move along the Z-axis on the fixed frame 31. The slider 33 is slidably installed on the sliding plate 32 and can move along the Y-axis on the sliding plate 32. The detection camera 34 is fixedly installed on the slider 33 and the lens of the detection camera 34 faces the conveyor belt 1. The strip light source 35 is installed on the other side of the fixed frame 31 and the LED beads of the strip light source 35 face the conveyor belt 1.

[0034] In this invention, as the cigarette box moves along the conveyor belt 1, it first passes through the coding device 2, which laser-codes the cigarette box. Then, it passes through the detection device 3, where the detection camera 34 detects the code on the cigarette box to determine if it is correct. Based on the detection result of the camera 34, the cigarette box undergoes further processing. This application mounts the detection camera 34 on a slider 33, which moves the camera 34 along the Y-axis, thereby adjusting the distance between the lens of the camera 34 and the cigarette box. Adjusting the position of the sliding plate 32 on the mounting bracket 31 adjusts the position of the camera 34 along the Z-axis, enabling the camera 34 to detect cigarette boxes of different heights, thus improving the applicability of the offline laser coding equipment for formed boxes.

[0035] In a preferred embodiment, the fixing frame 31 is provided with a first drive screw 311 and a first guide rod 312. The first guide rods 312 are arranged in pairs, and the first drive screw 311 is located between the two first guide rods 312, allowing the first drive screw 311 to rotate. The length directions of both the first drive screw 311 and the first guide rods coincide with the Z-axis direction. The slide plate 32 is provided with a first drive hole and a first guide hole. The first drive hole has an internal thread and is connected to the first drive screw 311. The first guide hole is fitted onto the first guide rod 312. Rotating the first drive screw 311 drives the slide plate 32 to move in the Z-axis direction (i.e., the slide plate 32 moves along the first guide rod 312). Similarly, the slide plate 32 is provided with a second drive screw 321 and a second guide rod 322. The second guide rods 322 are arranged in pairs, and the second drive screw 321 is located between the two second guide rods 322, allowing the second drive screw 321 to rotate. The slider 33 is provided with a second driving hole and a second guide hole. The second driving hole is provided with an internal thread and is connected to the second driving screw 321. The second guide hole is fitted on the second guide rod 322.

[0036] Furthermore, the laser offline coding equipment for formed boxes also includes a guiding device, which is located near the first end of the conveyor belt 1. The guiding device includes a pair of guide rails 4, with guide rails 4 on both sides of the conveyor belt 1. Each guide rail 4 includes an interconnected arc-shaped segment 41 and a straight segment 42. The straight segments 42 of the two guide rails 4 are parallel to each other, and the distance between the straight segments 42 of the two guide rails 4 is equal to the width of the cigarette box on the conveyor belt 1. When the cigarette box enters the conveyor belt 1 from the first end, it can enter between the two straight segments 42 under the guidance of the arc-shaped segments 41 of the two guide rails 4. At this time, the long side of the cigarette box is parallel to the straight segment 42. The arc-shaped segments 41 on the guide rails 4 are used to adjust the position of the cigarette box on the conveyor belt 1, thereby facilitating the coding device 2 to code the cigarette box in the correct position.

[0037] Furthermore, the laser offline coding equipment for formed boxes also includes a rejection device 5, which is located near the second end of the conveyor belt 1. The rejection device 5 includes an air nozzle 51 and a waste bin 52. The air nozzle 51 is located on one side of the conveyor belt 1, and the outlet of the air nozzle 51 faces the conveyor belt 1; the waste bin 52 is located on the other side of the conveyor belt 1, and the air nozzle 51 can blow the cigarette boxes on the conveyor belt 1 into the waste bin 52.

[0038] Finally, the laser offline coding equipment for the formed boxes also includes a feeding device 6, which includes a feeding belt 61 and a feeding bin 62. One end of the feeding belt 61 is connected to the first end of the conveyor belt 1. The feeding bin 62 is located above the feeding belt 61, and the bottom of the feeding bin 62 has an opening above the feeding belt 61. A feeding port 63 is provided at the bottom of the feeding bin 62 facing the conveyor belt 1. The cigarette boxes can move from the feeding port 63 onto the conveyor belt 1 under the action of the feeding belt 61. The feeding bin 62 stores cigarette boxes stacked sequentially, and the bottom cigarette box can move through the feeding port 63 onto the conveyor belt 1 under the action of the feeding belt 61.

[0039] The feeding hopper 62 includes a piecing plate 64, which faces the first end of the feeding belt and can move vertically. The space between the bottom of the piecing plate 64 and the feeding belt 61 is the feeding port 63. By adjusting the distance between the bottom of the piecing plate 64 and the feeding belt 61, it can be ensured that only one cigarette box passes through the feeding port 63 and enters the feeding belt each time.

[0040] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above.
